DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the invention and their features and advantages may be understood by referring to FIGS. 1-8, like numerals being used for like corresponding parts in the various drawings. Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

An image printing apparatus 1 as an example of an electric apparatus is a Multi Function Device (MFD) having a printing function, a copying function, a scanner function, and a facsimile function. In the first example shown in FIG. 1, a housing 2 as an apparatus body in the image printing apparatus 1 is provided. The housing 2 is made up of an injection-molded product formed of synthetic resin.

[Basic Configuration of Image Printing Apparatus]

On an upper surface of the housing 2, an upper body 3 which is made up of an injection-molded product formed of synthetic resin is mounted to an end of the housing 2 via first hinge portions 6 so as to be rotatably openable and closable in the vertical direction. In other words, when a front opening 2a is formed on a front side of the housing 2 (a right front side in FIG. 1), a pivotal axis as an axial line of rotation of the upper body 3 with respect to the housing 2 is positioned on a back side of the housing 2, which is the farthest from the front opening 2a. Arranged on the upper surface of the housing 2 at a portion near the front is an operating panel portion 4 having a display panel 4a and an operating switch 4b. The expressions “left” and “right” (“left side” and “right side”) mean the left and the right with respect to the housing 2 or the image printing apparatus 1 when opposing the front side (the side of the front opening 2a) of the housing 2 (hereinafter).

An image scanning apparatus 5 used for the copying function and the facsimile function is integrated in the upper body 3. The image scanning apparatus 5 includes a glass plate for placing documents thereon and a tight-contact image sensor (CIS: Contact image Sensor) for scanning the document arranged underside of the glass plate (both not shown). A document cover member 7 covers an upper surface of the glass plate and presses the document. The tight-contact image sensor is provided so as to be reciprocally movable along a guide shaft extending in a Y-axis direction in FIG. 1. A rear end of the document cover member 7 which covers an upper surface of the image scanning apparatus 5 is rotatably connected to a back side of the upper body 3 so as to be openable and closable via third hinge portions 8.

On the other hand, a lid member 2b for an ink storage section is provided on one side of the housing 2 (a front surface having the front opening 2a) so as to be openable toward the front. In the ink storage section, cartridges for individual colors, that is, ink cartridges for respective colors, not shown, namely, black (Bk), Cyan (C), Magenta (M), and yellow (Y) in this embodiment, are stored. The respective ink cartridges and ink-jet printheads 14 in an image printing unit 12 are connected with flexible ink supply tubes.

In contrast, as shown in FIG. 1 and FIG. 3, a paper feed cassette 15 (an example of a lower feed tray) configured to accommodate papers in an accumulated manner is arranged on a bottom portion of the housing 2 so as to be movable back and forth in an X-axis direction with respect to the front opening 2a. In this embodiment, the paper feed cassette 15 has a form to allow storage of a plurality of pieces of paper cut into A4 size, letter size, legal size, postcard size, and so on as the recording medium (paper) in a stacked (accumulated) state. One or more pieces of small-sized paper such as postcards can be placed on an auxiliary paper feed cassette (not shown) provided above the paper feed cassette 15 so as to be movable back and forth in the X-axis direction.

An inclined separation panel 16 for paper separation is arranged on an inner side of the paper feed cassette 15. A saw-tooth shaped resilient separation pad (not shown) for urging separation by coming into abutment with a leading end of the paper is provided at a center portion of the inclined separation panel 16 in the paper width direction.

A proximal end portion of a paper feed arm 17a of a paper feed unit 17 is mounted on the side of the housing 2 so as to be rotatable in the vertical direction, and rotation is transmitted from a drive source to a paper feed roller 17b provided at a distal end portion of the paper feed arm 17a by a tooth transmitting mechanism provided in the paper feed arm 17a. Then, the papers accumulated in the paper feed cassette 15 or the auxiliary paper feed cassette are selectively separated one by one and transported individually by the paper feed roller 17b and the resilient separation pad of the inclined separation panel 16. The separated paper is fed to the image printing unit 12 provided on an upper side (high position) of the paper feed cassette 15 via an U-shape path defined by a U-turn transporting unit 18 faced sideward and a substantially horizontal first transporting path 19.

The image printing unit 12 is supported by a box-shaped main frame 21 and a pair of left and right side panels thereof as shown in FIG. 3, and is formed between laterally elongated plate-shaped first and second guide members (not shown) extending in the Y-axis direction (primary scanning direction). A carriage having the ink-jet printhead 14 mounted on a lower surface thereof in the image printing unit 12 is slidably supported across the first guide member on an upstream side in the paper discharging direction and the second guide member on a downstream side thereof, and hence is reciprocally movable in the Y-axis direction.

In order to cause the carriage to make a reciprocal movement, a timing belt (not shown) is arranged so as to extend in the primary scanning direction (Y-axis direction) on an upper surface of the second guide member arranged on the downstream side in the paper discharging direction, and a CR (carriage) motor (not shown) that drives the timing belt is fixed to a lower surface of the second guide member.

A flat-shaped platen 26 extends in the Y-axis direction so as to face a lower surface of the printhead 14 of the carriage.

On the upstream side of the platen 26 in the paper discharge direction, a drive roller and a nip roller arranged below the drive roller so as to oppose thereto are arranged as a transporting (registration) roller pair 27 for transporting the paper to the underside of the printhead 14 as shown in FIG. 3. Also arranged on the downstream side of the platen 26 in the paper discharging direction is a paper discharge roller pair 28 including a paper discharge drive roller driven to transport the paper passed through the image printing unit 12 along the paper discharging direction and a spur roller urged toward the paper discharge drive roller so as to oppose thereto.

A paper discharge tray 20 in which the paper subjected to printing in the image printing unit 12 is discharged with a printed surface thereof faced upward is formed integrally on a front side of the auxiliary paper feed cassette (not shown), and a paper discharge port communicating with the paper discharge tray 20 is opened commonly with the front opening 2a of the housing 2.

[Configuration of First Manual Feed Tray]

Referring now to FIG. 3, FIG. 5A, and FIG. 5B, the configuration of the first example of a first manual feed tray 30 will be described.

The first manual feed tray 30 includes a pair of left and right arms 31, a placing panel 32 configured to connect the pair of arms 31, and side guides 33 provided on a front surface of the placing panel 32. Provided at proximal ends of the respective arms 31 are second hinge portions 34 for connecting the arms 31 to a back surface portion of the housing 2 so as to be rotatable in the vertical direction. The placing panel 32 is configured to place the printing medium to be manually fed, and an edge 32a of the placing panel 32 is positioned on the side close to axial centers 35 of the second hinge portions 34. The arms 31 are thicker than the placing panel 32.

In the first example, the first manual feed tray 30 is provided so as to be rotatable (pivotable) in the vertical direction about an axis of the second hinge portions 34. The second hinge portions 34 are set at positions on the side of an upper portion of a back side opening 41, which are slightly higher than a standard height of a second transporting path 22 and lower than the first hinge portions 6.

The side guides 33 include a pair of sliders apart from each other in the width direction, abutting panels 37 provided on the sliders so as to extend upright and hold both side edges of the printing medium in the width direction orthogonal to the feeding direction of the printing medium placed on the placing panel 32 from both sides so as to come into abutment therewith, rack rods 38 extending from the respective sliders in the width direction, and a pinion 39 rotatably provided on a lower surface of the placing panel 32 and engages the both rack rods 38. The abutting panels 37 are formed to increase in height from the placing panel 32 as they approach free ends of the arms 31. Conversely, the abutting panels 37 are formed to be lowered as they approach the second hinge portions 34. Therefore, they have a function as knobs which allow a user to hold and operate the abutting panels 37 with fingers easily.

The distance between the pair of the abutting panels 37 can be displaced in the wider and narrower direction by the user by holding one of the abutting panels 37 with his or her fingers and moving the same in the width direction of the printing medium. A lock member which is provided on a lower surface of the slider and is displaceable in engagement with engaging teeth formed on a back surface of the placing panel 32 (both not shown) is provided. Accordingly, the positions of the pair of abutting panels 37 can be maintained in a state in which a desired distance between the pair of abutting panels 37 is achieved.

The first manual feed tray 30 in use takes an obliquely upward position (an example of a feeding position and an example of a protruding position) on the outside of the back surface of the housing 2 (see the state indicated by a solid line in FIG. 3), and the recording medium on the first manual feed tray 30 can be fed to the substantially horizontal second transporting path 22 communicating with the first transporting path 19 and extending to a back surface 2c of the housing 2. The fed printing medium is transported from the second transporting path 22 to the image printing unit 12 via the registration roller pair 27, and is discharged from the first transporting path 19 to the front opening 2a after printing.

Provided on the back surface 2c of the housing 2 is the back side opening 41 which allows storage of the first manual feed tray 30 in a back side storage space 40 on a back side of the U-turn transporting unit 18 with a free end thereof faced downward. Therefore, when not in use, the first manual feed tray 30 can be stored in the back side storage space 40 on the back side with respect to the U-turn transporting unit 18 in a downwardly oriented position (an example of a retracted position), which is a position with the free end thereof faced downward (see the state indicated by a double-dashed chain line in FIG. 3). In this case, the entire unit of the side guides 33 of the first manual feed tray 30 is also stored in the back side storage space 40. A stopper (not shown) which can hold the oblique position of the first manual feed tray 30 when in use is provided.

According to the configuration as described above, the first manual feed tray 30 can be stored in the back side storage space 40 on the back side of the housing 2 when not in use without increasing the height of the housing 2 and, in contrast, a free end side of the first manual feed tray 30 approaches the upper surface of the upper body 3 when the first manual feed tray 30 is set to the position in use, so that visibility from an upper front side of the housing 2 for the user is advantageously ensured. Even when the upper body 3 is rotated in the opening direction about the first hinge portions 6 in a state in which the first manual feed tray 30 is stored in the back side storage space 40, the upper body 3 and the first manual feed tray 30 do not interfere with each other on the back side of the housing 2. In addition, when rotating the first manual feed tray 30 in a state of being stored in the back side storage space 40 to the position in use, the user can easily rotate the first manual feed tray 30 by holding a higher portion of the abutting panel 37 (a lower end side of the first manual feed tray 30 (free end side)).

Referring now to FIG. 4, a specific tray (also referred to as a label tray) which allows so-called label printing on a surface of an optical disk such as a CD-R or a DVD as an example of a third printing medium will be described.

[Configuration of Specific Tray]

FIG. 4 is a schematic perspective view of a specific tray 45, and a circular groove 47 which allows setting of an optical disk 46 such as the CD-R and the DVD as an example of the third printing medium is formed on a front surface of the specific tray 45 formed of synthetic resin so as to be depressed therefrom. A projecting portion 47a which is fitted to a center hole 46a of the optical disk 46 is formed at a center portion of the circular groove 47 having the same diameter as the optical disk 46, and the projecting portion 47a has a height which is the same as a depth of the circular groove 47. A front surface of the optical disk 46 is a label printing area 46b which allows printing of a label such as a title with the printing unit 12. In contrast, a back surface of the optical disk 46 is a recording area for data such as images or music.

Provided on the side of the front opening 2a in the housing 2 is a auxiliary transporting unit 48 configured to support both sides of the specific tray 45 including the optical disk 46 set thereon in the width direction and transport the specific tray 45 in the direction of the printing unit 12 along the first transporting path 19 (see FIG. 5A).

At a position in preparation where the specific tray 45 is not set, the auxiliary transporting unit 48 stops in the housing at a position close to the front opening 2a. When a tray set command is supplied to the image printing apparatus 1, the auxiliary transporting unit 48 is slightly lowered and then is partly exposed toward the front from the front opening 2a. In this state, the specific tray 45 including the optical disk 46 set thereon is placed on the auxiliary transporting unit 48. Subsequently, when a label print preparation command is issued, the auxiliary transporting unit 48 is moved toward the printing unit 12. At this time, vertical distances between the drive rollers and the driven rollers (spur roller) of the registration roller pair 27 and the paper discharge roller pair 28, respectively, are increased, and the specific tray 45 is inserted into a gap therebetween. Then, the distances between the drive rollers and the driven rollers (spur roller) are decreased and hence the specific tray 45 is clamped between the upper and lower rollers, and is passed through the second transporting path 22 by the reverse rotation of the two drive rollers, whereby the specific tray 45 can be transported to the position in preparation where a trailing end of the specific tray 45 projects outward from the back side opening 41 of the housing 2 by an adequate distance L1 (see FIG. 5A). Subsequently, when a label print command is issued, printing on the label printing area 46b of the optical disk 46 placed on the specific tray 45 is performed while the two drive rollers rotate intermittently in the normal direction.

The edge 32a of the placing panel 32 of the first manual feed tray 30 is positioned closer to the axial centers 35 of the second hinge portions 34 and a standard position of the specific tray 45 extending along the second transporting path 22 is positioned downward of the edge 32a of the placing panel 32 of the first manual feed tray 30 in a state of facing downward. Therefore, after the trailing end of the specific tray 45 advances and hits against the back surface of the placing panel 32, the first manual feed tray 30 can be rotated upward in association with further advancement of the specific tray 45.

The dimension L1 of outward projection of the trailing end of the specific tray 45 from the back side opening 41 of the housing 2 is set to be smaller than a maximum amount of projection L2 of a distal end (free end) of the first manual feed tray 30 when the first manual feed tray 30 is rotated upward from the stored position to the position in use, and to be smaller than the amount of projection of the distal end of the first manual feed tray 30 in the upward oblique position when in use (see FIG. 6).

Subsequently, detection of the position (rotated state) of the first manual feed tray 30 and presence or absence of insertion of the specific tray 45 into the housing 2, and a control unit 50 configured to perform an action of the image printing apparatus 1 on the basis of a detection signal therefrom will be described.

As shown in FIG. 3, FIG. 5A, and FIG. 6, a first sensor 51 for sensing the position (rotated state) of the first manual feed tray 30 is provided in the housing 2 in the vicinity of the second hinge portions 34 of the first manual feed tray 30. In contrast, a second sensor 52 which is capable of sensing whether or not the trailing end of the specific tray 45 inserted into the housing 2 projects from the back side opening 41 is provided in the housing 2 in the vicinity of the back side opening 41. As shown in FIG. 6, the first sensor 51 is a transmissive photo interrupter 51a or the like, and outputs an ON-OFF signal depending on the presence or absence of a detected portion 51b provided on a base portion of the first manual feed tray 30 so as to rotate integrally therewith.

In the example, the detected portion 51b intercepts light from the transmissive photo interrupter 51a (see the state indicated by a double-dashed chain line in FIG. 6) within a range of rotation from a position where the first manual feed tray 30 extends horizontally on the outside from the back surface (which corresponds to the maximum amount of projection L2) to a position where the first manual feed tray 30 is in use, that is, a position where the first manual feed tray 30 takes the oblique position, that is, a position where the free end side comes upper side on the outside of the back surface of the housing 2, so that the detection signal is “ON”. In a range of rotation from a position where the first manual feed tray 30 is positioned with the free end side faced downward to a state in which the first manual feed tray 30 is accommodated in the interior of the storage space 40, the detected portion 51b is positioned outside of the transmissive photo interrupter 51a and hence does not interrupt the light (see the state indicated by a solid line in FIG. 6), the detection signal is “OFF”.

The second sensor 52 provided in the second transporting path 22 is made up of a limit switch or the like, and when the trailing end of the specific tray 45 has passed through the second sensor 52 and is positioned on the outside of the back surface of the housing 2 (which corresponds to a printable position of the optical disk 46 on the specific tray 45), the detection signal is turned on. In the state therebefore, the detection signal is OFF.

FIG. 7 is a block diagram for control. The electronic control unit 50 such as a microcomputer is provided with a CPU 50a, a ROM 50b having a control programs stored therein and a RAM 50c for storing various data such as the detection signal therein, although they are not shown in the drawings. The first sensor 51, the second sensor 52, the operating switch 4b, the display panel 4a, the image scanning apparatus 5, the printing unit 12, and the auxiliary transporting unit 48 described above are connected to the control unit 50.

Subsequently, a mode of control by the control unit 50 will be described. As shown in a flowchart in FIG. 8, in a subroutine of a label printing process, whether or not the first sensor 51 is ON is determined first. If the user takes out the first manual feed tray 30 from the storage space 40, rotates upward, and sets the first manual feed tray 30 from the horizontal state to the usable state (state of being inclined obliquely upward), the first sensor 51 is determined to be ON (S1: yes). As shown in FIG. 6, the amount of projection when the first manual feed tray 30 is in the horizontal state is the maximum amount of projection L2. Therefore, by setting the image printing apparatus 1 at a position securing a horizontal distance between other objects (wall, etc.) 53a and the back surface 2c of the housing 2 to be larger than L2, the vertical rotation of the first manual feed tray 30 is not hindered. In contrast, is a horizontal distance between other objects (wall, etc.) 53b and the back surface 2c of the housing 2 is smaller than L2, the free end of the first manual feed tray 30 which is coming out from the storage space 40 is supported by the other objects (wall, etc.) 53b, so that the first sensor 51 is kept in an OFF state. In this case (S1: no), a massage “Open First Manual Feed Tray” is displayed (S2) on the display panel 4a. Therefore, the user inspects the position of the first manual feed tray 30.

The action to rotate the first manual feed tray 30 upward may be insertion of the specific tray 45 (referred as CD Holder in a flowchart provisionally) from the front opening 2a of the housing 2. In this case, as shown in FIG. 6, the trailing end of the specific tray 45 presses the back surface of the placing panel 32 of the first manual feed tray 30 faced downward, and pushes the first manual feed tray 30 upward about the second hinge portions 34. Anyhow, when the first sensor 51 is in an ON state (S1: Yes), a message “Set CD Holder” is displayed on the display panel 4a (S3). Since when the trailing end of the specific tray 45 (CD Holder) projects from the back surface of the housing 2 by the predetermined amount L1, the second sensor 52 is turned ON (S4: Yes), it is determined that printing on the optical disk 46 is possible, so that the label printing on the optical disk 46 on the specific tray 45 is performed (S5). When the label printing on one optical disk 46 is finished, the auxiliary transporting unit 48 is activated automatically, and the specific tray 45 (CD Holder) is ejected out from the front opening 2a of the housing 2 (S6).

With the control as described above, by securing a horizontal distance between a back surface of the image printing apparatus 1 and other objects such as a wall of a room to be slightly larger than the maximum amount of projection L2 of the first manual feed tray 30 at a position of installation of the image printing apparatus 1, the first sensor 51 and the second sensor 52 are both turned ON by inserting the specific tray 45 (CD Holder) using the auxiliary transporting unit 48, so that the label printing on the optical disk 46 is performed safely, reliably, and quickly. In addition, the other objects do not hinder the upward rotation of the first manual feed tray 30 or the projection of the trailing end of the specific tray 45 later, so that removal of hindrance of the label printing using the specific tray 45 is ensured.

Also, by holding the first manual feed tray 30 at a working position, manual feed printing using the first manual feed tray 30 can be performed in the state shown in FIG. 3. In this case, with the first manual feed tray 30 in the position in use, it is preferable that an upper side of an auxiliary horizontal guide plate extending from an upper end of the U-turn transporting unit 18 toward the back side opening 41 forms the second transporting path 22 so that the printing medium placed on the placing panel 32 is guided smoothly from the second transporting path 22 to the registration roller pair 27 (see FIG. 5A, FIG. 6).

As another embodiment, an auxiliary placing panel (not shown) for supporting a trailing end of the printing medium may be provided so as to be expandable or foldable in the first manual feed tray 30.

It is needless to say that the invention can be applied not only to the multifunctional image printing apparatus 1, but also to a single-function image printing apparatus. In this case as well, the invention achieves the effects and advantages as described above.

In the embodiments described above, the first sensor 51 detects the position of the first manual feed tray 30. Therefore, the first sensor 51 and the first manual feed tray 30 serves as a detecting device which detects whether a space is existing outside the apparatus. Alternatively, a sensor which detects whether the space is existing or not by detecting an object within a predetermined distance from the sensor can be applied. For example, the sensor may be configured to detect a light reflected from the object.
