Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a scanner device which reads film of a predetermined format and a control method thereof, and a film feeding device.
2. Description of Related Art
Services are currently available for users to have laboratory shops process negative or positive developed silver-salt-type film (135 mm film) by cutting the film in strips of six frames which are stored in negative sheets and returned to the user along with the prints, or mounting the film one frame at a time in mounts for use with a projector.
On the other hand, there is a new-standard film which is developed silver-salt-type film stored within a case which provides users with a service wherein a 40-exposure film for example is developed and processed in the laboratory shop, and following exposure, the film is wound again into the light-shielding case and stored therein, and the user is provided with a so-called index print on which all of the photographed frames are printed with the index numbers thereof.
Also, such developed silver-salt-type film of printed photographs can be read into a computer using a specialized scanner device which reads images with a photo-electric converting device, following which the image data can be output after certain processing, using various types of digital output devices such as ink-jet printers. Thus, users can obtain printed photographs without relying on laboratory shops. However, achieving such an arrangement is difficult in reality, since a great number of types and formats of scanners are required for scanner-reading and computer processing of all images on silver-salt-type film including 135 mm film, and reversible film mounted in slide mounts, resulting in a large system.
A known scanner device which handles two types of film, namely film strips and film stored in cartridges is disclosed in Japanese Patent Laid-Open No. 5-145838. However this arrangement is insufficient in handiness since attachments must be changed in order to deal with a plurality of film types, and the operator must make his/her own judgment whether or not a film is being processed.
Further, this arrangement is insufficient in that electrical circuit are required for each switch in the event that an opening/closing switch for mounting film stored in a cartridge and a force-eject switch for forcibly ejecting film being processed are separately provided, and the switching circuitry including the layout becomes complicated.
Now, the new-standard film is handled by the user and operator in the state of the film being wound and stored within the case, and ease of loading to cameras is the greatest advantage thereof.
U.S. Pat. No. 4,841,319 discloses a thrust-type film cartridge. This film cartridge is configured such that the film is ejected from a film ejecting opening by opening a light-shielding door provided to the ejecting opening and rotating a film supplying spool within the film cartridge. The new-standard film is approximately of the same construction.
Film feeding mechanisms for devices which use this thrust-type cartridge (i.e., cameras) include such as proposed in Japanese Patent Laid-Open No. 4-86633, for example, constructed such that the film is fed by driving with a roller, and the amount of film feeding is detected by the amount of roller rotation, following which driving force to the roller is cut off.
Also, the thrust-type cartridge returns to the user in the state that the film is completely wound within the cartridge following developing of the film, as well.
Accordingly, scanner devices which handle new-standard film comprised of developed silver-salt-film stored in a case must also provide ease of use, the same as the cameras.
The film which is extracted from the new-standard film case and sequentially run by a scanner is comprised to be rewound into the case following the reading thereof at the photo-electric conversion reading unit, but it cannot be said that there is no chance of trouble such as jamming occurring due to unforeseen causes, so damage to the film must be minimal in the event that such trouble does occur.
Accordingly, in the case of scanning film with a film scanner, the film must be fed from the cartridge, and the film must be fed at a constant speed. To this end, an actuator appropriate for constant-speed feeding such as a step motor or the like is employed, and a method is employed wherein the driving force thereof is transferred to a roller in the same manner as with a camera to feed the film.
Now, regarding the thrust-type cartridges, the film must be returned to the user in a completely wound state, following reading of the film with a film scanner, as well. In other words, the film is subjected to a process of being ejected from the cartridge (wound) within the film scanner and a process of being rewound within the cartridge.
Accordingly, it is desirable that scanning can be performed at both the time of winding the film and rewinding the film. Such an arrangement allows for pre-scanning to be performed at the time of winding the film so as to detect the state of the images and set the reading conditions thereof, and perform actual scanning at the time of rewinding. It is necessary to make the feeding speed of the film constant at the time of winding and at the time of rewinding and also prevent any warping from occurring in the film, in order to perform such bi-directional scanning.
Now, with the method wherein the film is fed by spool driving, such as proposed in Japanese Patent Laid-Open No. 4-69634, the outer diameter grows greater as the spool winds the film, resulting in the problem that accurate film feeding cannot be carried out.
Now, known original document transporting type scanner devices use silicon-elastomer rubbers for the cylindrical elastic portion of the driving roller for transporting the originals, so as to obtain desired friction.
Such silicon-elastomer rubbers are used in various devices, since the desired resistance can be obtained thereby, and such can be manufactured relatively inexpensively.
However, such silicon-elastomer rubbers have viscosity, which causes problems of adhesion of dust, and in cases the adhered dust may accumulate and be transferred into the surface of the original or onto the film, which has been seriously problematic in the event that the original or film is read with such dust thereupon.
Also, the known scanner device has independently provided a sensor for detecting whether or not a film strip has been mounted and a sensor for reading bar-code data provided to the film strip relating to the film are provided separately, so electrical circuits are required for each sensor, and the sensor circuitry including the layout becomes complicated, meaning that this arrangement falls short in this aspect also.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following is a detailed description of the preferred embodiments of the present invention, with reference to the attached drawings. First,
FIG. 1
is an external perspective view relating to the embodiments, showing the overall construction of the system for using the scanner device
1
.
In the Figure, there are various types of use of the scanner device
1
, but a representative method of use thereof will be briefly described with reference to the overall constructional diagram of the system as shown in FIG.
1
.
This scanner device
1
performs the following operations: (i) performs main scanning and sub-scanning of a negative or positive image recording medium on which a color or monochrome analog image is recorded; (ii) performs analog/digital conversion of the analog image obtained by photo-electric conversion of an image recorded on an image recording medium, by means of a photo-electric converter including a built-in high-resolution line image sensor; (iii) sends the digital signals obtained by this A/D conversion to an image processing unit
3
a
of a personal computer
3
via an interface cable
2
such as a SCSI cable or the like; (iv) the user confirms the read image on the screen
4
a
of the display device
4
which is a monitor device, and changes the image as desired by operating the operating unit
3
b
which includes a mouse, keyboard, etc., to synthesize, enlarge, reduce, paste, etc.; and (v) outputs the image thus obtained in color or monochrome on recording sheets of a certain size including standard paper by means of a recording device
5
including ink-jet printers, thus obtaining a recorded sheet P recorded with the image recorded at a desired size.
With the above-described as a basic usage form, the formats of image recording medium carrying analog images which can be handled with this scanner device
1
are can be generally divided into the following four groups:
First, a first image recording medium is negative and positive film F used for silver-salt-type cameras which are in widespread use today. For example, a 36-exposure developed strip of 135 mm film is cut into strips of 6 continuous frames, each strip being the same length, and stored in a negative sheet case and handed to the user along with the prints.
Consideration has be made so that the scanner device is capable of structurally handling 36-exposure 135 mm film which has not yet been cut into 6-frame slits, as well.
On the other hand, a second image recording medium is mounted film MF which is comprised of developed positive (reversible) film cut in single frames and mounted in slide frames to enable use mainly with slide projectors.
Also a third image recording medium is color or monochrome silver-salt photographs and various printed materials, these being reflective original documents G from which an analog image recorded on the surface thereof is read by reflection, such as an original document G of a panorama photograph which is inserted in the longitudinal direction in the direction of the arrow and is read.
Finally, a fourth image recording medium cartridge film CF corresponding to the Advanced Photo System. This Cartridge film CF is known art, but to make a brief description thereof, a 40-exposure film for example is wound on a built-in spool and stored in a case which shields the film from external light. The film is stored again in the case in a wound state following camera photography and processing by a laboratory shop, the user being provided with the film along with a so-called index print which has all of the frames printed with index numbers. Accordingly, the user indicates the desired index numbers in order to obtained the desired photographs. This film is capable of recording photography conditions and the like using electromagnetic means along with the image, and the user indicates this information when scanning the image.
This scanner device
1
is capable of handling all of the above first through fourth image recording mediums. The following is a schematic description of the operation procedures of each of the image recording mediums, with reference to FIG.
1
.

1
.
Accordingly, the continuous film unit
100
is provided so as to be insertable in the direction shown by an arrow A from the right opening portion
13
shown by broken lines, provided so as to open to the right and left as shown in the Figure at the front
1
a
of the scanner device
1
. In the event that the presence of the continuous film unit
100
is detected by an optical sensor which also serves as a bar-code reader for barcode provided to the top and bottom portions of the film, this sensor being the sensor k
3
provided near the right opening
13
of the device
1
, a later-described built-in motor m
2
is automatically activated upon reception of the second detection results, so that the inserted tip of the continuous film unit
100
is transported to the left opening
14
shown with solid lines, and the arrangement is such that the unit
100
automatically stops at the left opening
14
.
Following mounting of this continuous film unit
100
to the device
1
, preliminary sub-scanning of the film F is performed by manually setting a negative or positive film F of six continuous frames in the unit
100
in the direction indicated by the arrow B. The film F is transported in the reverse direction so as to perform sub-scanning of the image recording medium upon which the analog image is recorded, (i) main scanning and sub-scanning of the image recording medium upon which the analog image is recorded is performed, (ii) photo-electric conversion of the analog image recorded on the film F is performed by means of the photo-electric conversion including the aforementioned built-in high-resolution line image sensor while performing, the operations of (iii) through (v) are performed, and thus obtaining a recorded sheet P of output on recording sheets of a certain size including standard paper by means of a recording device
5
including ink-jet printers. Accordingly, this continuous film unit
100
is indispensable.
Also, in order to handle slide-mounted film MF of film mounted in a slide mount which is the second image recording medium, the slide film unit
200
is used in the state of the above continuous film unit
100
being removed from the device
1
.
This slide film unit
200
is constructed such that six slide-mounted films MF can be set from the upper opening thereof such that each are retained in certain positions. The overall length thereof is slightly linger than that of six frames of continuous film F, and the width dimensions ahead of and behind the slide film unit
200
is set at approximately 5 mm.
On the other hand, the width dimensions of the above continuous film F is around 0.15 mm, meaning that the later-described transporting functions are necessary for both.
This slide film unit
200
can be automatically mounted to the scanner device
1
in the same manner as with the above continuous film unit
100
, and accordingly, is provided so as to be insertable in the direction shown by an arrow A from the right opening portion
13
shown by broken lines, provided so as to open to the right and left as shown in the Figure at the front la of the scanner device
1
. In the event that the presence of the slide film unit
200
is detected by the optical sensor provided near the right opening
13
of the device
1
, the built-in motor is automatically activated upon reception of the detection results.
Consequently, the slide film unit
200
is transported to the left in the drawing to an appropriate position via the left opening
14
illustrated in the Figure in solid lines, and preliminary sub-scanning of the six mounted films MF in the slide mounts is performed by transporting in the reverse directions so as to perform sub-scanning. For example, preliminary sub-scanning of six of the mounted films MF set in slide mounts is performed, (i) the mounted films are transported in the reverse direction to perform sub-scanning, (ii) photo-electric conversion of the analog image is performed by means of the photo-electric converter including the aforementioned built-in high-resolution line image sensor, the operations of (iii) through (v) are performed, thus obtaining a recorded sheet P of output on recording sheets of a certain size including standard paper by means of a recording device
5
including ink-jet printers. Incidentally, the image formed on the emulsion surface of the film F mounted to the continuous film unit
100
and transported, and the image formed on the emulsion surface of the mounted film MF set to the slide film unit
200
differ in distance from the image reading surface of the later-described line image sensor, so the a converging lens is provided with an automatic focusing mechanism. Accordingly, accurate focusing of the image can be performed even in the event that the film F and the mounted film MF are each set backwards.
Also, the reflective original document G which is a third image recording medium includes original documents which are quite long in the sideways direction, such as panorama photographs and the like. The device
1
is constructed such that such original documents G and standard so-called service-size print photographs can be inserted in the direction of the arrow C in the document inserting/ejecting opening
8
provided to the lower portion of the front la of the device
1
as shown in the Figure, whereby the original document is automatically drawn in and read. After the reading operation, the original document is then ejected from the same inserting/ejecting opening
8
.
Accordingly, the external dimensions of the device
1
following the forward/rear directions are determined with consideration to the dimensions of panorama photographs following the longitudinal dimensions thereof. Provided to this inserting/ejecting opening
8
are original width adjusting plates
9
which are original width adjusting plates
9
which restrict the original document G in the width direction, these being arranged according to known arrangement such that moving one or both causes the plates to either be removed from a center position.
The cartridge film CF which is the fourth image recording medium is set in the direction shown by the arrow D to the cartridge film mounting unit
11
provided next to the left opening
14
in the front
1
a
of the device
1
as shown in broken lines in the Figure. Accordingly, the device
1
is provided with an opening
10
for allowing the mounting unit
11
to move forwards and backwards, so as to allow for storage of the cartridge film cartridge CF via the mounting hole
12
formed in the mounting unit
11
, following forward movement as described later.
Next, an indicator
7
comprised of a light-emitting diode or the like which is continuously lit according to the state of the main power being switched on to serve as an indicator for indicating the on/off state of the main electrical power switch provided to the rear
1
d
or the side
1
b
or
1
c
of the device
1
is provided to a portion to the upper right corner of the front
1
a
of the device
1
which does not interfere with the above units
100
or
200
when mounted.
Also, provided to the front
1
a
between the above left and right openings
13
and
14
is an indicator
15
which indicates the reading operation state of cartridge film, an indicator
16
which indicates the reading operation state of standard film F including 135 mm film and mounted film MF, and an indicator
17
which indicates the reading operation state of original documents G, these indicators being arrayed from the left to the right respectively, each constructed so as to indicate each mode as follows: a solid green for a waiting state, a blinking green for a normal operating state, and a blinking red for an abnormal state such as incorrect operation such as jamming.
Formed below these indicators
15
,
16
, and
17
is an eject switch
6
to be pressed in order to move the cartridge film Cartridge film mounting unit
11
from the opening
10
toward the front of the device
1
.
FIG. 2
is an external perspective view of the device
1
, showing the state wherein reading of an original has been completed and the eject switch
6
has been pressed.
In the Figure, the constructions which have already been described with reference to
FIG. 1
are denoted with the same reference numerals and description thereof will be omitted, with description being limited to unexplained portions. At the point that the eject switch
6
is pressed, a later-described mounting unit moving mechanism is activated, and the mounting unit
11
of the cartridge film CF is moved toward the front of the device
1
in the direction of the arrow D
1
via the opening
10
, so as to fill the left opening
14
. Accordingly, in this state, other mediums, i.e., film F or mounted film MF can not be accepted, at least visually.
In the state shown in the Figure, a lid
19
provided above the mounting unit
11
and axially borne is rotated in the direction of the arrow, so that the cartridge film CF film extracting opening CFa can face the device, regarding the mounting hole
12
of the mounting unit
11
. This resembles the film loading system for Advanced Photo System cameras, so users can use without feeling difficult.
Once set in the mounting hole
12
, the cartridge film CF is detected by a micro switch built into the mounting unit
11
, this detection causing the mounting unit moving mechanism to operate, moving the mounting unit
11
in the direction of the arrow D
2
, and at the same time the lid
19
closes.
The external dimensions of the device
1
defined by the width dimensions W and depth dimensions Y and height dimensions H are such that take into consideration usage in the state of a flatbed-type scanner for an A
4
size document, for example. Accordingly, the mounting operations of the above various mediums can be all performed from the front
1
a
side of the device
1
, in the case that a flatbed-type scanner is mounted. Also, consideration is taken so that the overall height is small when a flat-bed-type scanner is mounted.
In other words, each of the later-described transporting systems and optical systems are set according to such considerations.
Incidentally, regarding the preset embodiment, the arrangement is such that each of the units are mounted from the right, taking into consideration the face that the majority of people are right-handed, but it is needless to say that the device can be set to appropriately deal with left-handed people.
Next,
FIG. 3A
is an external perspective view illustrating the state of the continuous film unit
100
mounted to the device
1
, and
FIG. 3B
is an external perspective view illustrating the state of the slide film unit
200
mounted to the device
1
.
First, in
FIG. 3A
, once the continuous film unit
100
is mounted via the right opening
13
shown by broken lines to the device
1
and is automatically moved to the predetermined position, the resultant state is such as shown in the Figure. Now, the operator holds the certain film F including 135 mm film so as not to directly touch the image surface, and sets the film in the continuous film unit
100
. The film F is then transported in the reverse direction (arrow H) from the left opening
14
and sub-scanning thereof is performed.
Also, in
FIG. 3B
, once the slide film unit
200
set with up to six mounted films MF beforehand is mounted via the right opening
13
shown by broken lines to the device
1
and is automatically moved to the predetermined position, the resultant state is such as shown in the Figure. This is then transported in the reverse direction (arrow H) so that there is partway protrusion from the left opening
14
and sub-scanning thereof is thus performed.
The above construction means that new cartridge film CF cannot be handled in this state, at least visually.
FIG. 4
is an exterior perspective view illustrating the mechanism of device
1
, and the constructions which have already been described are denoted with the same reference numerals and description thereof will be omitted.
First, the original G reading unit
20
shown with broken lines is constructed as follows: Force is obtained from a first motor m
1
such as a stepping motor or the like, and urethane rubber is used for right and left elastic members
21
a
which come into direct contact with the surface of the original. A pair of roller pairs, comprised of the elastic members being fixed to shafts
21
b

21
and idlers
22
which are in constant contact with the drive rollers
21
at a certain pressure and follow the rotation thereof, is provided, with another such roller pair being also provided downstream, and further two sets being provided to an unshown base.
Provided between these roller pairs are two cold cathode tubes
23
by which high brightness can be obtained at low temperature, fixed to the base (unshown), so as to irradiate the surface of the original document G.
Provided above the two cold cathode tubes
23
is a reflecting mirror
24
having a reflecting surface

1
from the surface of the original in between the two cold cathode tubes
23
toward a converging lens
25
, converging to a line image CCD
26
of a certain resolution fixed to the base, so as to perform main scanning of the original document surface.
Incidentally, these are stored in an unshown dark box, shielded from exterior light. Also, the state of transportation of the original document G is continuously monitored by sensor K
1
and sensor K
2
which are optical sensors comprised of photo-emitting photo-receptor diodes provided to the positions shown in the Figure, thus enabling detecting of presence or absence of original documents, and detecting of completion of the reading operation.
Next, the construction of the 135 mm film F reading unit
30
is as follows: fixed to the unshown base is a second motor m
2
which is capable of reverse rotation such as a stepping motor and is driven according to set driving pulses, so as to drive the total four first drive rollers
32
via a force transmitting mechanism shown is solid lines in the Figure regarding this second motor m
2
.
Each of the first drive rollers
32
is comprised of a shaft
32
b
upon which is provided a pair of elastic members
32
a
using urethane rubber at the upper and lower portions where direct contact is made with the outer surface of the image recording portion of each frame of the film F.
Also, provided to positions opposing each of the first drive rollers
32
are idler rollers
33
, rotatable and pressed, so as to maintain a gap smaller than the approximately 5 mm which is the width of the above slide film unit
200
, these being provided rotatably to the base
31
.
On the other hand, a cathode tube
34
is provided between the first drive rollers
32
centrally positioned, such that the image of the film F is directed toward the converging lens
44
, converging to the line image CCD
46
of the certain resolution fixed to the base, so as to perform main scanning and sub-scanning of the film F and the mounted film MF. Also, these are stored in later-described dark box, shielded from exterior light.
Also, an optical path converting mechanism
40
provided with a reflecting mirror
48
is provided in the optical axis L
3
shown in the Figure by a single-dot broken line connecting the converging lens
44
and cathode tube
34
, arranged so as to be rotatable by 45/ by means of a fourth motor m
4
, constructed so as to be in states of shielding the optical axis L
3
and directing the optical axis L
3
to the converging lens
44
.
Further provided between this optical path converting mechanism
40
and the converging lens
44
is a filter converting mechanism
41
having a plurality of filters, provided so as to be rotated by a fifth motor m
5
, constructed so as to insert an appropriate filter
42
into the optical axis L
3
, according to the concentration of the film F negative, positive, or image of the various stipulations.
Next, the cartridge film CF reading unit which is the fourth image recording medium is constructed as follows:
A sensor K
4
comprised of a micro switch is provided to the base plane of the mounting hole
12
of the above mounting unit
11
to which the cartridge film CF is to be mounted. Also provided to the bottom plane of the mounting hole
12
is a dowel member
61
shown by broken lines, with a member constructed so as to engage the film winding spool of the cartridge film CF being provided rotatably thereto, so that the mounting unit
11
meshes with this dowel member
61
via an unshown planetary gear mechanism as to a seventh motor m
7
at the position shown by solid lines.
Also, a rack
62
is extended from the mounting unit
11
as shown in the Figure, such that the mounting unit
11
is driven to the solid-line and broken-line positions in the Figure via the opening
10
of the above device
1
, by reverse driving of an eighth motor m
8
provided to the output shaft of a pinion
63
which constantly meshes with this rack
62
.
In the state of this mounting unit
11
being mounted such, a cold cathode tube
64
is provided downstream from the film extracting opening CFa of the cartridge film CF, and with the optical axis L
2
(shown by single-dot broken line) connecting the cold cathode tube
64
and the above optical path converting mechanism
40
is directed to the above converging lens
44
by the optical path converting mechanism
40
being rotated about 45/ to rotate to the position shown by broken line, thus sharing the line image CCD
46
of the certain resolution between the above films F and MF.
Provided further downstream from the cold cathode tube
64
is a driving roller
68
having an elastic cylindrical urethane rubber member as the driving portion thereof, arranged so as to directly receive force from a ninth motor m
9
, and is constructed so as to pinch the cartridge film CF being fed from the film extracting opening CFa for the cartridge film CF by means of driving of the above seventh motor m
7
between this driving roller
68
and an idle roller
67
provided so as to oppose this driving roller
68
, such that the cartridge film CF passes over the cold cathode tube
64
at a constant speed, thereby performing main scanning and sub-scanning reading operations.
Provided further downstream from the driving roller
68
and idle roller
67
is a winding spool
66
arranged to obtain force from the above ninth motor m
9
via a clutch
65
, and the cartridge film CF is temporarily all wound into the winding spool
66
after reading.
Following the above reading operation, the ninth motor m
9
is reversed, and the cartridge film is fed out backwards with an appropriate amount of back tension provided to the cartridge film CF and the spool within the case of the cartridge film CF is rotated by the dowel member
61
by driving the seventh motor m
7
, thereby storing all. Subsequently, this is ejected from the opening
10
.
In this way, moving the mounting unit
11
in the direction following the film ejecting direction for cartridge film CF structured to wind film on a spool stored within a cartridge, damage to the film can be kept at a minimal level in the event of jamming of the film.
Specifically, in the event that the indicator
15
shown in
FIG. 1
turns red, the winding operation can be terminated and the top plate of the device
1
opened, allowing for the film to be directly grasped from above.
FIG. 5
is an explanatory diagram of the operations of the reading units of FIG.
4
. The constructions in the Figure which have already been described are denoted with the same reference numerals and description thereof will be omitted.
First, at the point that the original document G is inserted into the reading unit
20
, the sensor Kl detects the leading edge of the original, activates the first motor m
1
and rotates the drive roller
21
in a counter-clockwise direction, causing the original document G to run past two cold cathode tubes
23
, and directs the optical axis Ll to the converging lens
25
with a reflecting mirror
24
having a reflecting surface
24
a
of the width of the original document G, thereby reading at the CCD
26
. The drive roller
21
here can be constantly kept clean, since urethane rubber which has less viscosity than silicone rubber is used at the portions coming into direct contact with the surface of the original. Accordingly, the user's originals can be kept from being soiled. Once this reading is completed, the first motor m
1
is reverse-rotated and the original is ejected.
Next, after standard film F is set in the continuous film unit
100
or mounted film MF is set in the slide film unit
200
, detection of starting of mounting is detected by a sensor K
3
, causing the second motor m
2
to be activated which rotates the four first drive rollers
32
, thereby performing the certain reading operation.
At this time, each of the first drive rollers
32
is constructed such that a pair of elastic members
32
a
using urethane rubber is provided on the shaft
32
b
at the positions at which direct contact is made with the outer sides of each of the frames of the film F.
Next, the reading operation of the cartridge film CF which is the fourth image recording medium is performed as follows: Once the mounting unit
11
is moved to the position shown by solid lines by means of operation of the eighth motor m
8
, the seventh motor m
7
is activated, the film of the cartridge film CF is fed between the drive roller
68
and idle roller
67
, past the cold cathode tube
64
to the downstream of the film extracting opening CFa of the cartridge film CF. Next, the ninth motor m
9
is activated, driving the drive roller
68
and idle roller
67
, so as to perform reading while winding the whole with the winding spool
66
. Following the above reading operation, the ninth motor m
9
is reversed and the cartridge film CF is fed out backwards with an appropriate amount of back tension provided to the cartridge film CF and the spool within the case of the cartridge film CF is rotated by the dowel member
61
by driving the seventh motor m
7
, thereby storing all. Subsequently, this is ejected from the opening
10
.
Next, the slide film unit
200
as described above is constructed in a storable manner so that six slide mounted films MF can be set from the upper opening and retained in a certain position, the overall length being somewhat longer that six frames of developed continuous film F, and since the forward and back width dimensions of the slide film unit
200
is approximately 5 mm and the width dimensions of the continuous film F is 0.15 mm, the space between the drive roller
32
and idle roller
33
must be 5 mm or more, and description will be made with reference to the cross-sectional diagrams of principal members of FIG.
6
and
FIG. 7
regarding a mechanism which enables use of both the units
100
and
200
. Here, the constructions which have already been described are denoted with the same reference numerals and description thereof will be omitted.

FIG. 6
, the converging lens
44
is constructed of a lens
45
built into a lens barrel, configured so as to converge the optical axes L
2
and L
3
to the CCD
46
, with a screw-hole member
47
further provided to this lens barrel. This screw-hole member
47
screws to a worm screw
43
fixed to an output shaft of a sixth motor m
6
fixed to the unshown base. The above construction provides for an automatic focusing mechanism. Also, an opening for introducing the optical axis L
2
is formed to the dark box
36
at the position shown in the Figure.
Also, an engaging recessed portion
50
for fixing the continuous film unit
100
unmovable at the time of setting is provided to the dark box
36
. Each of the idle rollers
33
are provided in a state pressed toward the drive rollers
32
by means of spring
51
, and constructed so as to come into contact with the free roller
52
and rotate in the state that the continuous film unit
100
has been mounted, as shown in the Figure.
On the other hand, sensors K
3
, K
5
, K
6
, and K
7
are provided at the positions shown in the Figure, monitoring each operation. Also, an aperture
38
is provided at the center position facing the cathode tube
34
.
Now,
FIG. 7
illustrates the state in which the slide film unit
200
is mounted and being transported in the direction of the arrow H, in which case the slide film unit
200
is pinched between the idle roller
33
and the drive roller
32
. That is, the width dimensions t of the unit
200
are approximately 5 mm, so the slide film unit
200
can be transported as such.
The configuration of the continuous film unit
100
will be described based on the frontal view shown in FIG.
8
and the cross-sectional diagram of the principal components shown in FIG.
9
.
In
FIG. 8
, the continuous film unit
100
is provided with a base

56
and aperture
74
for passing light source from the cathode tube, and also has rotatably built in a total of eight of the above free rollers
52
. The continuous film unit
100
also has free rollers
53
rotatably built in, as well.
Next, making reference further to
FIG. 10
, the base
55
is arranged such that the lever
58
is movable in the left and right directions, and is provided with the plate
77
integrally. The end

a
of this plate
77
operates upon an operating end
80
a
of a member
80
which is provided rotatably around a pin
78
and also pressed in a counter-clockwise direction by a torsion spring
79
, constructed such that the unit
100
is inserted from the right opening
13
shown in FIG.
1
and moved to the predetermined mounting position, whereupon the member
80
engages the recessed portion
50
as shown in FIG.
9
.
In order to disengage this engaged state, the operator operates the lever
58
in the right direction, and removes the member
80
from the recessed portion
50
.
FIG. 11
is a plan view describing the construction of the drive rollers
32
and idle rollers
33
.

and
FIG. 13
, each of the drive rollers
32
are axially borne in a rotatable manner by the base
90
and each having gears
94
fixed to the ends of the shafts. Also, the elastic member portions
32
a
protrude from windows opened in the base
90
, and the windows are arranged along the protrusions
91
guiding the units
100
and
200
, so that the elastic member portions
32
a
come into contact with the outer plane pair each of the units, thus providing transporting force.
On the other hand, in
FIG. 12
, the above idle rollers
33
are arranged so as to partly protrude from the windows
71
in the base
70
.
Also,
FIG. 14
is a front view of the device
1
as viewed from the inside outwards, with springs
51
operating on each of the idle rollers
33
as shown in the Figure, and with the idle rollers
33
coming into contact as to the running direction of the slide film unit
200
.
Also, FIG.
15
and
FIG. 16
illustrate the state of activation following mounting of the above continuous film unit
100
, and is configured in the Figure such that the elastic portion
32
a
of each of the drive rollers are positioned to the portion with bar-code formation which is the feeding perforation portion of the film F.
Also, the sensor K

100
upside down.
FIGS. 17A through 17E
are diagrams for describing the operation of the running state of the film F. In
FIGS. 17A and 17B
, pre-pre-scanning of the film F is performed, scanning of one line in the vertical direction in the generally center position of the first frame is executed, and an automatic focusing adjustment mechanism is activated so that the contrast is maximal based on this data. Filter replacement is performed based on judgment made from the image concentration, focusing of the converging lens and setting of the desired filter is performed, following which the film is returned in the reverse direction in
FIG. 17C
, preparation is made for pre-scanning. All frames are fed in FIG.
17
D and pre-scanning is performed, and reverse transporting is made in
FIG. 17E

[Description of Operation of the Scanner Device]
Next, description of operation of the scanner device according to the present embodiment will be made.
<First Embodiment>
First, description will be made regarding a first embodiment according to the present invention. FIG.
19
and
FIG. 20
are flowcharts illustrating the operations of the first embodiment.
With the first embodiment, the scanner device is arranged such that, for example, in the event that mounting of the continuous film unit
100
or the slide film unit
200
is attempted for processing 135 mm film while cartridge film CF is being processed, control is made so that mounting of the continuous film unit
100
or the slide film unit
200
is prohibited until reading processing of the cartridge film is completed.
Making more specific description, as shown in
FIG. 19
, in step S
2
, the CPU judges whether or not the eject switch
6
is on or not. In the event that the eject switch
6
is on in step S
2
(Yes in step S
2
), the flow proceeds to step S
4
, and in the event that the eject switch
6
is not on in step S
2
(No in step S
2
), the flow proceeds to a later-described step S
18
.
In step S
4
, the CPU judges whether any of the film types is being currently processed. Judgment of whether processing of film is being performed or not is made according to the detection signals of the sensor K
3
shared for bar-code, the CF present sensor F
4
, and the original document presence sensor K
2
. In the event that processing of film is not being performed in step S
4
(No in step S
4
), the flow proceeds to step S
6
and sends the Cartridge film mounting unit
11
to the open position. The operator mounts the cartridge film CF to the mounting hole
12
in step S
8
, and the detection signals for the CF detecting sensor K
4
are output to the CPU
323
. In the case that judgment is made in step S
10
that cartridge film CF is present, based on the output signals of the CF detecting sensor K
4
, the Cartridge film mounting unit
11
is stored in the closed position. Subsequently, the flow proceeds to step S
200
, and executes a later-described sub-routine program for processing the cartridge film images.
In the event that processing of film is being performed in step S
4
(Yes in step S
4
), the flow proceeds to step S
12
and judges whether or not the film being processed is cartridge film CF or not. In the event that the film being processed in step S
12
is cartridge film CF (Yes in step S
12
), the flow proceeds to step S
14
and forbids acceptance of film, and also blinks the red light of the cartridge film CF indicator
15
to notify the user that cartridge film CF is being processed. In the event that the film being processed in step S
12
is not cartridge film CF (No in step S
12
), the flow proceeds to step S
16
and forbids acceptance of any type of film.
Next, as shown in
FIG. 20
, in the event that the eject switch is not on in step S
2
(No in step S
2
), the flow proceeds to step S
18
, and makes judgment whether any of film F, cartridge film CF, or original documents G have been mounted to the scanner device, based on detection signals of the sensor K
3
shared for bar-code, CF presence sensor K
4
or original document sensor K
2
. Now, the sensor K
3
shared for bar-code detects mounting of negative film, unmounted positive film, and mounted positive film. In the event that any of the sensors detects mounting in step S
18
(Yes in step S
18
), the flow proceeds to step S
20
, and in the event that none of the sensors detects mounting in step S
18
(No in step S
18
), the flow returns to step S
2
.
In step S
20
, the CPU
323
makes judgment whether any of types of film are being processed. Judgment of whether any of types of film are being processed or not is made based on detection signals of the sensor K
3
shared for bar-code, CF presence sensor K
4
or original document sensor K
2
. In the event that film is not being processed in step S
20
(No in step S
20
), the flow proceeds to step S
22
and judges the type of film mounted to the scanner device. In the event that 135 mm film F is mounted in step S
22
, the flow proceeds to step S
100
, and performs the 135 mm film image processing sub-routine program described in FIG.
24
. Also, in the event that an original document G is mounted in step S
22
, the flow proceeds to step S
300
, and performs the original document image processing sub-routine program described in FIG.
27
.
Next, in the event that there is film being processed in step S
20
(Yes in step S
20
), the flow proceeds to step S
24
and forbids acceptance of any type of film.
Hence, according to the first embodiment, the operator can be notified by forbidding processing a one type of film while another is being processed, thereby preventing mistaken operation.
<Second Embodiment>
Next, description will be made regarding a second embodiment according to the present invention. FIG.
21
and
FIG. 22
are flowcharts illustrating the operations of the second embodiment.
With the second embodiment, the scanner device is arranged such that, for example, in the event that mounting of the 135 mm film is attempted while cartridge film CF is being processed, control is made so that the 135 mm film is accepted and image processing preparations are made, and processing of the 135 mm film is conducted following processing of the cartridge film being completed. In other words, with the second embodiment, control is performed so that image processing is performed in the order that the 135 mm film, cartridge film or original document is mounted.
Making more specific description, as shown in
FIG. 21
, in step S
32
, the CPU judges whether or not the eject switch
6
is on or not. In the event that the eject switch
6
is on in step S
32
(Yes in step S
32
), the flow proceeds to step S
34
, and in the event that the eject switch
6
is not on in step S
32
(No in step S
32
), the flow proceeds to a later-described step S
58
.
In step S
34
, the CPU
323
judges whether any of the film types is being currently processed. Judgment of whether processing of film is being performed or not is made according to the detection signals of the sensor K
3
shared for bar-code, the CF present sensor F
4
, and the original document presence sensor K
2
. In the event that processing of film is not being performed in step S
34
(No in step S
34
), the flow proceeds to step S
50
and sends the Cartridge film mounting unit
11
to the open position. The operator mounts the cartridge film CF to the mounting hole
12
in step S
8
, and the detection signals of the CF detecting sensor K
4
are output to the CPU
323
. In the case that judgment is made in step S
54
that cartridge film CF is present, based on the output signals of the CF detecting sensor K
4
, the Cartridge film mounting unit
11
is stored in the closed position. Subsequently, the flow proceeds to step S
200
, and executes a sub-routine program described in
FIG. 26
for processing the cartridge film images.
In the event that processing of film is being performed in step S
34
(Yes in step S
34
), the flow proceeds to step S
36
and judges whether or not the film being processed is cartridge film CF or not. In the event that the film being processed in step S
36
is cartridge film CF (Yes in step S
36
), the flow proceeds to step S
56
and forbids acceptance of film, and also blinks the red light of the cartridge film CF indicator
15
to notify the user that cartridge film CF is being processed. In the event that the film being processed in step S
36
is not cartridge film CF (No in step S
36
), the flow proceeds to step S
38
and sends the Cartridge film mounting unit
11
to the open position. The operator mounts the cartridge film CF to the mounting hole
12
in step S
38
, and the detection signals of the CF detecting sensor K
4
are output to the CPU
323
. In the case that judgment is made in step S
42
that cartridge film CF is present, based on the output signals of the CF detecting sensor K
4
, the Cartridge film mounting unit
11
is stored in the closed position. Subsequently, in step S
44
, other film is being processed, so the state is that of waiting for image processing of cartridge film. In this image processing waiting state, the mounted cartridge film is held in the Cartridge film mounting unit
11
in the event that it is not in use. In step S
46
, the CPU
323
waits until the processing of the other film is completed, and when the processing of the other film is completed (Yes in step S
46
), judgment is made in step S
48
whether or not there is other film waiting for processing or not. In the event that there is other film waiting for processing in step S
48
, (Yes in step S
48
), the flow returns to step S
46
and waits until the processing of the other film is completed. In the event that there is no other film waiting for processing in step S
48
, (No in step S
48
), the flow proceeds to step S
200
, and executes a sub-routine program described in
FIG. 26
for processing the cartridge film images.
Next, as shown in
FIG. 22
, in the event that the eject switch is not on in step S
32
(No in step S
32
), the flow proceeds to step S
58
, and makes judgment whether any of film F, cartridge film CF, or original documents G have been mounted to the scanner device, based on detection signals of the sensor K
3
shared for bar-code, CF presence sensor K
4
or original document sensor K
2
. In the event that any of the sensors detects mounting in step S
58
(Yes in step S
58
), the flow proceeds to step S
60
, and in the event that none of the sensors detects mounting in step S
58
(No in step S
58
), the flow returns to step S
32
.
In step S
60
, the CPU
323
makes judgment whether any of types of film are being processed. Judgment of whether any of types of film are being processed or not is made based on detection signals of the sensor K
3
shared for bar-code, CF presence sensor K
4
or original document sensor K
2
. In the event that film is not being processed in step S
60
(No in step S
20
), the flow proceeds to step S
62
and judges the type of film mounted to the scanner device. In the event that 135 mm film F is mounted in step S
62
, the flow proceeds to step S
100
, and performs the 135 mm film image processing sub-routine program described in FIG.
24
. Also, in the event that an original document G is mounted in step S
62
, the flow proceeds to step S
300
, and performs the original document image processing sub-routine program described in FIG.
27
.
Next, in the event that there is film being processed in step S
60
(Yes in step S
60
), the flow proceeds to step S
64
, and since other film is being processed, the state is that of waiting for image processing of the 135 mm film or original document. In this image processing waiting state, the mounted the 135 mm film or original document is held in the continuous film unit
100
or the reflective original document reading unit
20
in the event that it is not in use. In step S
66
, the CPU
323
waits until the processing of the other film is completed, and when the processing of the other film is completed (Yes in step S
66
), judgment is made in step S
68
whether or not there is other film waiting for processing or not. In the event that there is other film waiting for processing in step S
68
, (Yes in step S
68
), the flow returns to step S
66
and waits until the processing of the other film is completed. In the event that there is no other film waiting for processing in step S
68
, (No in step S
68
), the flow proceeds to step S
62
and judges the type of film mounted to the scanner device, and executes subsequent processing.
Hence, according to the second embodiment, film is processed in the order that it is mounted, so there is no need to wait for film being processed to finish in order to mount film, meaning that processing efficiency and handiness is improved.
<Third Embodiment>
Next, description will be made regarding a third embodiment according to the present invention.
FIG. 23
is a flowchart illustrating the operations of the third embodiment.
With the third embodiment, the scanner device is arranged such the eject switch
6
serves both for opening and closing the Cartridge film mounting unit
11
and forced ejection functions of film being processed. In the event that the operator presses the eject switch
6
during processing of any of the 135 mm film, cartridge film, or original document, the processing is terminated and the film is ejected, or, in the event that there is no film being processed, the Cartridge film mounting unit
11
is open/close controlled.
Making more specific description, as shown in
FIG. 23
, in step S
72
, the CPU judges whether or not the eject switch
6
is on or not. In the event that the eject switch
6
is on in step S
72
(Yes in step S
72
), the flow proceeds to step S
74
, and in the event that the eject switch
6
is not on in step S
72
(No in step S
72
), the flow proceeds to either the above-described step S
18
or step S
58
.
In step S
74
, the CPU
323
judges whether any of the film types is being currently processed. Judgment of whether processing of film is being performed or not is made according to the detection signals of the sensor K
3
shared for bar-code, the CF present sensor F
4
, and the original document presence sensor K
2
. In the event that processing of film is not being performed in step S
74
(No in step S
74
), the flow proceeds to step S
80
and sends the Cartridge film mounting unit
11
to the open position. The operator mounts the cartridge film CF to the mounting hole
12
in step S
8
, and the detection signals of the CF detecting sensor K
4
are output to the CPU
323
. In the case that judgment is made in step S
84
that cartridge film CF is present, based on the output signals of the CF detecting sensor K
4
, the Cartridge film mounting unit
11
is stored in the closed position. Subsequently, the flow proceeds to step S
200
, and executes a sub-routine program described in
FIG. 26
for processing the cartridge film images.
In the event that film is being processed in step S
74
(Yes in step S
74
), the flow proceeds to step S
76
and terminates the film image processing that is currently being processed, and ejects the film of which processing has been terminated in step S
78
. Subsequently, the flow proceeds to step S
80
, and sends the Cartridge film mounting unit
11
to the open position.
Thus, according to the third embodiment, sharing functions of the film opening and closing switch and forced ejection switch simplifies the switching circuitry and reduces costs.
<Image Processing Operation for 135 mm Film>
Next, image processing operation of 135 mm film with the scanner device will be described. FIG.
24
and
FIG. 25
are flowcharts illustrating this image processing operation of 135 mm film.
With the image processing operation of 135 mm film, the scanner device performs both detection of insertion and reading of the bar-code with the sensor K
3
shared for bar-code. The 135 mm film is fed out to around the center of the first frame in the first pre-scan, around the center of the first frame of the 135 mm film is read, and AF processing is executed. Subsequently, the 135 mm film is returned to the original position, all of the frames of the 135 mm film are fed out in the second pre-scan in which the various parameters are set, following which control is performed to read image data from the 135 mm film in the main scan. Incidentally, as shown in
FIG. 1
, the 135 mm film is developed negative film F, unmounted positive film, and mounted positive film MF.
Specifically, as shown in
FIG. 24
, in step S
102
, the CPU
323
waits for the continuous film unit to be mounted. In the event that mounting of the continuous film unit is detected in step S
102
(Yes in step S
102
), the second motor is driven in step S
104
and the continuous film unit is driven to the predetermined position. After the continuous film unit is detected by the sensor K
3
shared for bar-code, the second motor is driven until detected by the end sensor K
5
.
In step S
106
, the flow waits for the 135 mm film to be mounted. Once the sensor K
3
shared for bar-code detects mounting of the 135 mm film in step S
106
(Yes in step S
106
), the second motor is driven in step S
108
and is sent to the initial position. In step S
110
, the barcode provided to the top and bottom portions of the film is read by the sensor K
3
shared for bar-code as the 135 mm film F is fed to the initial position. This bar-code has recorded information such as the film manufacture, ISO value, and so forth.
In step S
112
, the cold cathode tube which serves as an illumination light source is lit. In step S
114
, the F indicator
16
blinks green to indicate that film is being scanned. In step S
116
, the 135 mm film or slide film unit is fed out to around the center of the first frame in the first pre-scan (See FIG.
17
(
b
)), and in step S
118
, around the center of the first frame of the film is read, and in step S
120
judgment is made from the image concentration of the read first frame whether the film is negative or positive film. In the event that the film fed in step S
120
is positive film, the flow proceeds to step S
122
, and executes AF processing as an initial setting. Also, in the event that the film fed in step S
120
is negative film, the flow proceeds to step S
130
, the filter
41
is set, and executes AF processing as an initial setting in step S
132
. The reason that the filter is set in step S
130
is in order to remove the orange color of the negative film.
In step S
124
, the 135 mm film or slide film unit is returned to the initial position (See FIG.
17
(
c
)), and in step S
126
all of the frames of the 135 mm film or slide film unit are fed out as a second pre-scan (See FIG.
17
(
d
)), and in step S
128
, parameters such as brightness of the light source, accumulation time for the CCD, exposure amount such as gain, are set, thereby preparing to read the image.
Next, as shown in
FIG. 25
, in step S
134
, the second motor is reversed as main scanning and the film is fed in the reverse direction (See FIG.
17
(
e
)), and the image of each frame is read in step S
136
. In step S
138
, the processing of steps S
134
and
136
is repeated until the images of all frames have been read, and at the point that images of the certain number of frames have been read, the flow proceeds to step S
140
and switches the F indicator
16
from blinking green to solid green, indicating that image reading has been completed. In step S
142
, the cold-cathode
34
serving as the light source is turned off, and the second motor is stopped in S
144
and image processing of the 135 mm film or positive film is completed.
As described above, the scanner device performs both detection of insertion and reading of the bar-code with the sensor K
3
shared for bar-code, meaning that the number of sensors can be reduced, simplifying the sensor circuitry and reducing cost.
Also, performing auto-focusing and judging whether the film is negative film or positive film in a first pre-scan using the first frame of the film prior to the second pre-scan for setting film parameters allows for image reading with the film format having been accurately judged.
<Image Processing Operation of Cartridge Film>
Next, the image processing operation of cartridge film will be described.
FIG. 26
is a flowchart indicated the image processing operation of cartridge film.
With image processing operation of cartridge film, the scanner device is controlled so as to first feed out all frames of the cartridge film in a pre-scan and perform color correction, and then subsequently read the images from the cartridge film in the main scanning.
Specifically, as shown in
FIG. 26
, in step S
202
, the CPU
323
activates the fourth motor, and in step S
204
sets the reflecting mirror
48
in the direction of the cartridge film. In step S
206
, the cold cathode tube
64
which serves as an illumination light source is lit. In step S
208
, the film indicator
16
blinks green to indicate that film is being scanned. In step S
210
, the ninth motor is activated, and in step S
212
, film is fed out to around the center of the first frame approaches the imaging optical axis as a first pre-scan, and one line of image is read. After executing AF processing with that data in step S
213
a
, the film is rewound to the initial position in step S
213
b
, following which all of the frames are fed out as a second pre-scan and roughly read in step S
213
c
. In step S
214
, the various parameters are set, thereby preparing to read the image.
Next, in step S
216
, the cartridge film of which all frames had been fed out is rewound to original position. In step S
218
, the cartridge film is fed out again for main scanning, and the image of the certain frames is read in step S
220
. In step S
222
, the processing of steps S
218
and S
220
is repeated until the images of all frames have been read, and at the point that images of the certain number of frames have been read, the flow proceeds to step S
224
and switches the film indicator
16
from blinking green to solid green, indicating that image reading has been completed. In step S
226
, the cold-cathode
64
serving as the light source is turned off, and the seventh motor is driven in steps S
228
and S
230
to rewind the cartridge film, and the eighth motor is driven in steps S
232
and S
234
to move the Cartridge film mounting unit
11
to the open position, thus completing image processing of the cartridge film.
<Image Processing Operation of Original Documents>
Next, the image processing operation of original documents will be described.
FIG. 27
is a flowchart indicated the image processing operation of original documents.
With image processing operation of original documents, the scanner device is controlled so as to first feed out the entire original document in a pre-scan and perform color correction, and then subsequently read the image from the original document in the main scanning.
Specifically, as shown in
FIG. 27
, in step S
302
, the CPU
323
lights the cold cathode tube
23
which serves as an illumination light source. Upon the sensor K
1
detecting insertion of the original document in step S
303
, the G indicator
16
blinks green in step S
304
to indicate that an original document is being scanned. In step S
306
, the first motor is activated, and in step S
308
, the entire original document is fed out as a pre-scan, and in step S
310
, the various parameters are set, thereby preparing to read the image.
Next, in step S
312
, the first motor is reversed, main scanning is performed in step S
314
, and the entire image of the original document is read in step S
316
. The flow waits in step S
318
until the main scanning is completed, and once the main scanning is completed, the flow proceeds to step S
320
and switches the original document indicator
17
from blinking green to solid green, indicating that image reading of the original document has been completed. In step S
322
, the cold-cathode
23
serving as the light source is turned off, and the first motor is reverse-driven in step S
324
to return the original document to the original document insertion/ejecting opening, thus completing image processing of the original document.
[Fourth Embodiment]
FIG. 28
is an external perspective view of the film scanner device according to the fourth embodiment. This film scanner device is connected to an unshown host computer, and operations other than inserting and removing the film cartridge (e.g., reading a film image) are performed according to commands input from a host computer.
In
FIG. 28
,
401
denotes a cartridge tray, and
402
is an eject switch for causing the cartridge tray to extend from or to be stored inside the main unit.
FIGS. 29 through 31
illustrate the detailed construction of the cartridge tray
411
. In FIG.
29
and
FIG. 31
,
401
a
denotes a rack portion (with the rack teeth and the like being omitted and indicated by slanted lines), wherein driving force being transmitted from an unshown motor to the rack portion causes the cartridge tray
401
to be extended from or stored to the main unit. As shown in
FIG. 31
, formed above the cartridge tray
401
is a cartridge chamber
401
b
of which the top is open, the cartridge CF being mounted to and removed from this cartridge chamber
401
b.
403
denotes a tray lid, which is rotatably attached to the upper portion of the cartridge tray
401
by a pin
404
. A cartridge depressor
406
is formed on the rear side of this tray lid
403
, positioning the cartridge CF within the cartridge chamber
401
b
in the event that the tray lid
403
is closed, as shown in FIG.
29
and
FIG. 30. 405
denotes a torsion spring, which presses the tray lid
403
in the direction of opening.
The cartridge tray
1
constructed such is extended from the cart tray
1
, as shown in FIG.
32
. Since the tray lid
403
does not come into contact with the X portion of the scanner main unit in this extended state, so the tray lid
403
opens by means of the pressing force of the torsion spring
405
, thereby allowing mounting of the cartridge CF to the cartridge chamber
401
b
. Then, once the cartridge tray
401
is stored within the scanner main unit, as shown in
FIG. 30
, the tray lid
403
is pressed by the X portion of the scanner main unit, and is closed against the force of the torsion spring

is a line sensor, which is fixed to a base plate provided to the side of the imaging surface side. This line sensor

434
.
436
denotes a tray guide bar, which guides the movement of the cartridge tray
401
relative to the scanner main unit.
Next, description will be made regarding the operation of the scanner device. First, when the eject switch
402
shown in
FIG. 28
is pressed, the cartridge tray
401
receives driving force from an unshown motor to the rack portion
401
a thereof, and is extended from the scanner (see FIG.
32
), being guided by the cart tray guide bar
436
. Then, the cartridge CF is inserted from the top into the cartridge chamber of which the tray lid
403
is opened. Pressing the eject switch
402
once more causes the aforementioned unshown motor to rotate in reverse, so that the cartridge tray
401
is stored within the scanner main unit (see FIG.
30
). At this time, the tray lid
403
is pressed by the X portion and gradually closes against the force of the torsion spring
405
.
Next, film feeding operation in the direction of winding the film is started, by instruction from the unshown host computer. First, an unshown door motor is rotated forwards, thus driving the transmission gear
413
shown in
FIG. 33
, and rotating the door gear in the forward direction.
In the event that the thrust motor
407
is rotated forwards in this state, the planetary gear
409
a
meshes with the fork gear
411
, causing forward rotation thereof, so the film is fed out from the cartridge CF.
In the event that the stepping motor
414
is also rotated forwards while the thrust motor
407
is rotated forwards, the driving force thereof is transmitted to the feeding roller
422
, via the lower friction gear
417
, idling gear
425
, roller deceleration gear
426
, and roller driving gear
423
. The film which has been fed out to the position at which it is pinched between the feeding roller
422
and sub-roller
424
begins being driven in the winding direction by these rollers
422
and
424
. Incidentally, the film feeding speed of the fork gear
411
is made to be slower than the film feeding speed of the feeding roller
422
, thereby placing driving force from the film upon the fork gear
411
so that the engagement between the planetary gear
409
a
and the fork gear
411
is dissolved, and consequently the fork gear
411
rotates freely. Accordingly, the only member driving the feeding of the film is the feeding roller
422
alone, and accurate film feeding can be conducted by controlling the stepping motor
414
. Moreover, the film feeding speed of the fork gear
411
is made to be slower than the film feeding speed of the feeding roller
422
, so there is no flexing of film positioned between the feeding roller
422
and the spool within the cartridge (fork gear
411
). Accordingly, reading of the film image by the line sensor can be performed properly.
On the other hand, the rotation of the lower friction gear
417
is transmitted to the upper friction gear
416
by friction between the washer
420
and pressure spring
419
, is further transmitted to the spool gear
427
a
via the spool transmission gear
494
, and the clutch planetary gear
431
which has orbited to a position of meshing with the clutch sun gear
430
and spool gear
427
a
, thereby rotating the winding spool
427
. The winding spool
427
winds the film which has been fed into the spool chamber by means of the feeding roller
422
. The film winding speed of the winding spool
427
is set to be somewhat faster than the film feeding speed of the roller
422
by means of the gear ratio of the gears, so there is no flexing of film positioned between the feeding roller
422
and the winding spool
427
and the film is wound onto the winding spool
427
.
Now, since the film wound onto the winding spool
427
increases in diameter as the amount of the film increases, the film winding speed at the perimeter of the film increases even though the rotation speed of the winding spool is the same. However, in the event that the film winding speed as to the film feeding speed by the feeding roller accelerates to a speed exceeding a certain range (a range within which there is no effect on film feeding by the feeding roller
422
), the rotational load of the winding spool
427
which pulls the film nipped between the feeding roller
422
and the sub-roller
424
increases, so slippage occurs between the washer
420
attached to the upper friction gear
416
to which the load is transmitted and the pressure spring
419
, thereby decreasing the rotational speed of the winding spool
427
. Accordingly, the film winding speed is automatically controlled so that there is always an appropriate degree of tension to the film feeding speed by the roller
422
, and consequently, the feeding roller
422
can constantly feed film in the winding direction at a constant speed.
In the event that a rewinding instruction is input from the host computer, the stepping motor
414
starts reverse rotation. Accordingly, the feeding roller
422
also reverse and the film is driven in the direction of being rewound.
Also, the thrust motor
407
is also rotated in reverse simultaneously with the reverse rotation of the stepping motor
414
. Accordingly, the planetary gear
409
a
and the fork gear
411
mesh and the fork gear
411
rotates, so the spool is rotated within the cartridge engaged with the fork
411
a
and film rewinding is started.
Now, the film rewinding speed by the fork gear
411
(spool within the cartridge) is set to be somewhat faster than the film feeding speed of the roller
422
, so there is no flexing of film and the film is rewound into the cartridge CF at a constant speed.
On the other hand, in the event that the stepping motor is reversed, the meshing between the planetary gear
431
and the spool gear is disengaged, so the winding spool is free. Accordingly, the only member driving the feeding of the film is the feeding roller
422
alone, and accurate film feeding can be conducted by controlling the stepping motor
414
. Moreover, the film rewinding speed of the fork gear
411
and spool in the cartridge is made to be faster than the film feeding speed of the feeding roller
422
, so there is no flexing of film positioned between the feeding roller
422
and the spool within the cartridge (fork gear
411
). Accordingly, reading of the film image by the line sensor
433
can be performed properly even during the process of rewinding.
Incidentally, in the event that the film rewinding speed increases according to the increase in film wound onto the spool within the cartridge, it is preferable for means to be provided for controlling the driving speed of the fork gear
411
so that the film rewinding speed as to the film feeding speed by the feeding roller
422
does not accelerate to a speed exceeding a certain range (a range within which there is no effect on film feeding by the feeding roller
422
), so that the feeding roller
422
can constantly feed film in the rewinding direction at a constant speed.
Once the film has been thus rewound, the unshown door motor is reversed and the transmission gear
413
is driven, reversing the door gear
412
so that the light-shielding door of the cartridge CF is closed. Then, pressing the eject switch
402
extends the cartridge tray
401
from the scanner main unit, thereby allowing the cartridge CF to be removed from the cartridge tray
401
.
Incidentally, in the above embodiment, the driving by the feeding roller
422
and winding spool
427
is performed by a single stepping motor
414
at the time of winding film, in order to reduce the number of motors and related parts, but the present intention can be applied to a scanner of a construction wherein the feeding roller
422
and winding spool
427
are driven by separate motors.
As described above, according to the present embodiment, the film between the feeding roller and cartridge can be fed at a constant speed and without flexing, for both winding and rewinding of the film. Accordingly, employing the film feeding device according to the present invention facilitates realizing of a film reading device which is capable of accurate reading of film images for both winding and rewinding of the film.
Also, employing means for maintaining the difference between the film winding speed by the winding spool and the film feeding speed by the feeding roller within a certain range, and means for maintaining the difference between the film rewinding speed by the spool within the cartridge and the film feeding speed by the feeding roller within a certain range, allows for the film feeding speed by the feeding roller to be maintained at a constant speed regardless of the amount of film on either spool.
