Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates electronic equipment, and more particularly to electronic equipment having on its front side an openable and closable front panel.
2. Description of the Related Art
Installation of electronic equipment such as an audio device and a navigation device on a vehicle has widely been put into practice.
On the other hand, use of a card-type recording medium having a small size, called a “memory card” has also recently been generalized.
It has recently become possible to store information, which is to be used in the above-mentioned electronic equipment, in the card-type recording medium, so as to provide information sharing between the electronic equipment and a domestic or personal computer, as well as between a plurality of electronic equipment.
With respect to installation of the above-mentioned card-type recording medium on electronic equipment, a casing of the electronic equipment, which has a stationary front panel
101
as shown in
FIG. 9
, is embedded into a dashboard of a vehicle. As a result, it is necessary to form a slot-shaped insertion opening
106
into or from which the card-type recording medium is to be loaded or unloaded, on any place of the front panel
101
.
It is however necessary to provide parts such as an operating dial
102
, operating mode buttons
105
, an operation displaying unit
104
and selection buttons
103
a
and
103
b
, by which the electronic equipment is caused to function, on the above-mentioned front panel
101
. Accordingly, the above-mentioned insertion opening
106
must be formed on a place other than the above-mentioned parts such as the operating dial
102
. Formation of the insertion opening
106
is however restricted by design which is made when determining arrangement of the parts such as the operating dial
102
on the front panel
101
, thus causing problems.
The insertion opening
106
is exposed on the front panel
101
, resulting in an increased possibility that the card-type recording medium loaded into the insertion opening
106
may be stolen, thus also causing problems.
There has also been known electronic equipment, which is to be mounted on a vehicle and has an openable or closable front panel. FIG.
10
(
a
) is a partial side view of typical electronic equipment
200
in which a front panel
201
is opened by swinging the front panel
201
around a pivot shaft
206
provided on the lower side of the front panel
201
, while moving forward a supporting member
202
to which the pivot shaft
206
is connected. FIG.
10
(
b
) is a partial side view of the other typical electronic equipment
200
in which a front panel
201
is opened by swinging the front panel
201
around a pivot shaft
206
.
In either case, there is adopted a structure that an insertion opening
205
for the card-type recording medium MC is formed on an inner wall
204
, which is exposed from the front end opening of the casing of the electronic equipment when the front panel
201
is kept in the opened position (i.e., a state as shown in the lower portions of FIGS.
10
(
a
) and
10
(
b
)), and a connector
203
into which the card-type recording medium MC is to be inserted is further provided in a place corresponding to the insertion opening
205
.
However, the card-type recording medium MC, which has an extremely small size, is connected to the connector
203
so as to project from the above-mentioned inner wall
204
by a small length. As a result, it is not easy to pull out the card-type recording medium MC from the insertion opening
205
, thus causing a problem, even when the front panel
201
is opened as shown in the lower portions of FIGS.
10
(
a
) and
10
(
b
).

having a rack portion
21
a
, a gear train including gears
21
b
,
21
c
, a driving motor (not shown) and a swing arm
25
.
The supporting member
9
, which is formed of a rectangular plate, is placed on the bottom surface of the casing C so as to be slidable back and forth relative to the opening of the casing C. The supporting member
9
has opposite front end portions to which the above-mentioned pivot shafts
7
,
7
are pivotably connected, respectively
The slidable arm
9

has an elongated guide slot
9
b
in its longitudinal direction and the rack portion
21
a
at its rear ends. The slidable arm
9
a
is secured on the one side of the supporting member
9
. The casing C has a supporting pin
28
projecting inwardly so that the supporting pin
28
is inserted into the elongated guide slot
9
b
of the slidable arm
9
a
. The same supporting mechanism or any other mechanism for slidably supporting the supporting member
9
may be provided on the other side of the supporting member
9
. As a result, the slidable arm
9
a
slides together with the supporting member
9
relative to the casing C.
The gears
21
b
,
21
c
are rotatably supported on one of base frames
20
,
20
of the casing C. The gear
21
c

The swing arm
25
that is placed on the opposite side to the slidable arm
9
a
in the casing C, has one end, which is pivotably connected to the casing C by means of a pin
26
(which is a first pivot shaft) as shown in FIGS.
3
(
a
) and
3
(
b
), and the other end, which is pivotably connected to the upper portion of the front panel
3
A by means of the other pin
29
(which is a second pivot shaft). The same swing arm
25
may be provided on the other side.
The opening and closing mechanism having the above-described structure moves the front panel
3
A from the closed position to the opened position so that the front surface of the front panel
3
A faces generally upward, while pushing forward a lower portion of the front panel
3
A toward a user of the electronic equipment
1
A and lowering an upper portion thereof. As a result, the inner wall
1
a
of the casing C, which is concealed by means of the front panel that is kept in the closed position, is exposed from the opening of the casing C by moving the front panel
3
A from the closed position to the opened position. Accordingly, when the front panel
3
A is opened, it is possible to insert an optical disc into the slot
2
provided on the inner wall
1
a
of the casing C. The optical disc is loaded from the slot
2
so that the reproducing unit reproduces information such as musical information recorded in the optical disc.
As shown in FIG.
2
(
b
), the recording medium receiving unit
11
includes a receiving member
30
, a holding mechanism
31
, a plurality of terminals
32
, an eject lever
10
a
and a return spring
30
a
. The receiving member
30
has an insertion hole
35
into or from which a card-type recording medium MC is to be inserted or removed. The holding mechanism
31
holds the card-type recording medium MC inserted into the insertion hole
35
of the receiving member
30
, or relieves the holding of the card-type recording medium MC. The terminals
32
electrically connect the card-type recording medium MC to the reproducing unit to output information, which has been recorded in the card-type recording medium MC, into the reproducing unit, on the one hand, and to input information from the reproducing unit into the card-type recording medium MC. The eject lever
10
a
is slidably mounted on the receiving member
30
in the horizontal direction so that the front end of the eject lever
10
a
can come into contact with the eject button
10
provided on the front panel
3
A, in case where the front panel
3
A is kept in the opened position. The eject lever
10
a
slides between an operation position and an ejection position. The return spring
30
a
imparts a resilient force for returning the eject lever
10
a
to the operation position to the eject lever
10
a
. The recording medium receiving unit
11
having the structure described above is mounted on the central portion of the supporting member
9
.
When the card-type recording medium MC is inserted into the receiving member
30
in a direction shown by an arrow in FIG.
2
(
b
), terminals of the card-type recording medium MC come into electric contact with the plurality of terminals
32
of the recording medium receiving unit
11
. As a result, there can be carried out execution of outputting information, which has been recorded in the card-type recording medium MC, into the reproducing unit, on the one hand, and of inputting information from the reproducing unit into the card-type recording medium MC.
When the card-type recording medium MC is inserted into the recording medium receiving unit
11
to be kept operable, the eject lever
10
is kept in the operating position by means of the return spring
30
a
so that the front end of the eject lever
10
moves toward the rear end of the eject button
10
provided on the front panel
3
A. Accordingly, if the front panel
3
A is kept in the opened position, it is possible to push the eject button
10
as exposed so as to eject the card-type recording medium MC.
Now, description will be given below of operation of the front panel
3
A with reference to FIGS.
3
(
a
) and
3
(
b
). FIG.
3
(
a
) is a cross sectional view cut along the line III—III in FIG.
2
(
a
), illustrating a state in which the front panel
3
A is kept in the closed position as shown in FIG.
1
(
a
). FIG.
3
(
b
) is a cross sectional view illustrating a state in which the front panel
3
A is kept in the opened position as shown in FIG.
1
(
b
).
When the front panel
3
A is kept in the closed position as shown in FIG.
3
(
a
), the supporting member
9
and the slidable arm
9
a
are retracted in the left-hand direction in FIG.
3
(
a
) together with the recording medium receiving unit
11
in which the card-type recording medium MC is received. In such a state, the end of the card-type recording medium MC, which is projected from the receiving member
30
as shown in FIG.
3
(
a
), is concealed by means of the lower portion of the front panel
3
A. Accordingly, when the front panel
3
A is kept in the closed position, the recording medium receiving unit
11
is inaccessible so that neither insertion of the card-type recording medium MC into the receiving member
30
nor removal of it therefrom can be carried out.
Operation of the driving motor (not shown) causes the gears
21
b
and
21
c
to rotate so that the slidable arm
9
a
, which has the elongated slot
9
b
into which the supporting pin
28
of the casing C is inserted, slides forward (i.e., in the right-hand direction in FIG.
3
(
b
). The recording medium receiving unit
11
also slides forward together with supporting member
9
and the slidable arm
9
a.
The opposite front end portions of the supporting member
9
are pivotably connected to the pivot shafts
7
,
7
provided on the lower opposite sides of the front panel
3
A, respectively. In addition, the upper portion of the front panel
3
A is connected to the casing C by means of the swing arm
25
. Accordingly, slide of the supporting member
9
causes the lower portion of the front panel
3
A to be pushed forward toward a user of the electronic equipment
1
A and the upper portion thereof to be lowered so that the front surface of the front panel
3
A faces generally upward, with the result that the front panel
3
A moves from the closed position as shown in FIG.
3
(
a
) to the opened position as shown in FIG.
3
(
b
).
When the front panel
3
A is kept in the opened position in this manner, the inner wall
1
a
is exposed from the opening of the casing C and the recording medium receiving unit
11
, which is mounted on the supporting member
9
, moves forward so that the insertion hole
35
thereof is exposed and accessible through the recess
3
b
of the front panel
3
A. In the light of the mounting structure of the recording medium receiving unit
11
, the supporting member
9
serves as a device for sliding the recording medium receiving unit
11
between a retracted and inaccessible position and an extended and accessible position in the same direction as the moving direction of the lower portion of the front panel
3
A in synchronization with movement thereof utilizing the opening and closing mechanism.
As a result, the card-type recording medium MC received in the recording medium receiving unit
11
moves forward to a prescribed position in which the recording medium MC can easily be removed from the insertion hole
35
. In such a state, a pushing operation of the eject button
10
relieves the hold of the card-type recording medium MC, which is caused by the holding mechanism
31
, and moves forward the card-type recording medium MC. The card-type recording medium MC can therefore be pulled out from the recording medium receiving unit
11
.
In the above-described first embodiment of the electronic equipment of the present invention, the recording medium receiving unit
11
is concealed and inaccessible in case where the front panel
3
A is in the closed position and the recording medium receiving unit
11
is displaced along with movement of the front panel
3
A so as to be exposed and accessible when the front panel
3
A moves from the closed position to the opened position. It is therefore possible to carry out an easy operation of loading and unloading the card-type recording medium MC and to reduce the possibility of theft of the card-type recording medium MC.
In addition, it is not necessary to form any insertion hole for the card-type recording medium MC on the front surface of the front panel
3
A, thus relieving restriction in design of the front panel
3
A.
The recording medium receiving unit
11
is mounted on the supporting member
9
, which is movable along with the movement of the front panel
3
A, thus ensuring a stable and smooth slide of the recording medium receiving unit
11
.
[II] Second Embodiment
Now, the second embodiment of the present invention will be described with reference to FIGS.
4
(
a
) and

, which projects from the end of the card compartment
51
on the opposite side to the insertion hole
43
.
The pair of base plates
53
is formed of a metallic plate so as to serve as a mounting base. Each of the base plate
53
has a slot
53
a
. The base plates
53
are secured on the bottom of the recess formed on the rear surface of the front panel
3
E by means of screws, respectively, so as to be in parallel to each other. The base plate
53
projects upward in a perpendicular direction to the rear surface of the front panel
3
E.
The root ends
52
b
of the supporting arms
52
and the corresponding ends of the base plates
53
are pivotably connected to each other by means of a pair of pivot shafts
42
, respectively. The pivot shafts
42
extend in parallel to the rear surface of the front panel
3
E so as to be co-axial to each other. Accordingly, the card compartment
51
is swingable in both directions as shown in arrows in FIG.
8
(
b
) on a plane perpendicular to the rear surface of the front panel
3
E.
Each of the extension coil springs
55
, which is placed in the slot
53
a
of the base plate
53
, has one end
55
b
that is connected to a spring engaging portion
53
b
formed on the base plate
53
and the other end
55
a
that is connected to a spring engaging portion
52
d
formed on the root end
52
b
of the supporting arm
52
. Such coil springs
55
impart a resilient force to swing the card compartment
51
to the projected position.
The locking mechanism
57
is composed of a lock lever
58
, a hook member
56
and a coil spring
60
. The lock lever
58
, which has an L-shape as shown in FIG.
8
(
b
), is provided at its one end with an engaging pin
58
a
. The lock lever
58
is pivotably mounted on the inner surface of one of the base plate
53
by means of a supporting pin
59
so that the supporting pin
59
and the above-mentioned engaging pin
58
a
extend in parallel to the above-mentioned pivot shafts
42
. The hook member
56
is formed on the lower and portion of the supporting arm
52
on the opposite side to the root end
52
b
so as to be capable of engaging with the above-mentioned engaging pin
58
a
of the lock lever
58
. The coil spring
60
is mounted on the lock lever
58
so as to impart a resilient force to turn the lock lever
58
counterclockwise in FIG.
8
(
b
) to the lock lever
58
. There is also provided a stopper (not shown) to limit the swing range of the lock lever
58
in the counterclockwise direction mentioned above.
The lock releasing mechanism is composed of a release button
61
and a link mechanism for mechanically connecting the release button
61
to the lock lever
58
. The pushing operation of the release button
61
causes the lock lever
58
to turn clockwise in FIG.
8
(

) to release the locking condition.
Now, description of operation of the swing mechanism as described above will be given below. When the card-type recording medium MC is loaded, the release button
61
is pushed to swing the card compartment
51
to the projected position under the function of the extension coil springs
55
. In such a state, the card-type recording medium MC is inserted into the insertion hole
43
of the card compartment
51
by a manual operation.
Then, when the card compartment
51
is pushed down against the extension coil springs
55
by a manual operation so that it reach the prescribed position, the hook member
56
of the supporting arm
52
comes into contact with the engaging pin
58
a
of the lock lever
58
to turn the lock lever
58
clockwise in the FIG.
8
(
b
) against the coil spring
60
. Continued pushing operation causes the lock lever
58
to turn counterclockwise under the function of the coil spring
60
, while engaging the engaging pin
58
a
of the lock lever
58
with the hook member
56
of the supporting arm
52
. Consequently, the card compartment
51
is locked in the retracted position and the loading operation of the card-type recording medium MC is completed in this manner.
When the card-type recording medium MC is unloaded, the release button
61
is pushed to turn the lock lever
58
clockwise in FIG.
8
(
b
) against the coil spring
60
so as to swing the card compartment
51
to the projected position under the function of the extension coil springs
55
. In such a state, the card-type recording medium MC can be removed from the insertion hole
43
of the card compartment
51
by a manual operation.
In the fifth embodiment, the recording medium receiving unit
11
is swingable on the plane perpendicular to the rear surface of the front panel
3
E. The loading or unloading operation of the card-type recording medium MC can therefore be facilitated. In addition, it is possible to effectively utilize the area of the front panel
3
E, permitting use of the recording medium receiving unit
11
having a relatively large size without enlarging the front panel
3
E.
