DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device mounted so that a panel is driven by a driving mechanism.

[0002]

2. Description of the Related Art In general, some electronic devices such as a car stereo mounted on an automobile have a means for preventing theft by hiding the electronic device mounted on a vehicle when a user leaves the vehicle.

In a vehicle-mounted electronic device equipped with such anti-theft means, a front panel portion on which an operation unit, a display unit, and the like are arranged is rotatably mounted on, for example, a device body by a gear mechanism. In this front panel part,
An operation display surface on which an operation unit, a display unit, and the like are arranged is provided on the surface thereof, and a rear panel of the operation display surface is configured as a panel having a design consistent with the peripheral portion of the device body in the instrument panel in the vehicle cabin. Provide a camouflage surface.

[0004] When the user leaves the car,
The in-vehicle electronic device rotates (turns) the front panel by driving a gear mechanism so that the camouflage surface of the front panel portion faces the interior of the vehicle. Thereby, the in-vehicle electronic device is hidden by covering the front surface of the device main body with the camouflage surface, and is camouflaged as if the device main body does not exist.

Conventionally, as a vehicle-mounted electronic device capable of automatically reversing the front panel portion as described above, for example, one disclosed in Japanese Patent Application Laid-Open No. 9-267699 has been proposed.

In the on-vehicle electronic device described in Japanese Patent Application Laid-Open No. 9-267699, the operation panel is mounted on the front surface of the device main body so as to move the rotation axis while rotating the operation panel by a driving gear mechanism. A first operation state in which a normally used operation surface of the operation panel is driven by the driving gear mechanism to be a front surface, and a second operation state in which a blind plate surface on the back side of the operation panel is a front surface. Perform a transition operation.

In this drive gear mechanism, a rotation shaft is disposed at one end in the width direction of the operation panel. Also, the rotation axis of the operation panel is mounted so as to move between the upper front part and the lower front part of the electronic device.

[0008] In this drive gear mechanism, the operation panel is rotated by 180 ° during the operation of moving the rotation axis of the operation panel between the upper front part and the lower front part of the electronic device. Perform the operation of turning it upside down by rotating it in front of the vehicle-mounted electronic device.

[0009]

In such a vehicle-mounted electronic device, the driving gear mechanism rotates the operation panel in front of the vehicle-mounted electronic device to turn it over. For this reason, the drive gear mechanism strictly performs the operation of moving the rotation axis of the operation panel between the upper front part and the lower front part of the electronic device and the operation of rotating the operation panel 180 ° at a predetermined accurate timing. In addition, since the operations must be performed simultaneously and in parallel, a large number of gears are used, and the configuration is complicated.

For this reason, the operation panel driven and operated by the driving gear mechanism using a large number of gears in a complicated manner has a first operation state in which the normally used operation surface of the operation panel is the front side, and an operation state. When set to the second operation state in which the blind plate surface on the back side of the panel is the front surface, the backlash in a gear train using a large number of gears and the manufacturing error of the driving gear mechanism cause so-called rattling. As a result, there is a problem that the operation panel is moved in the rotation direction by the amount of backlash or backlash of the gear.

In a state where the operation panel is set to the second operation state in which the back side of the blindfold plate faces the front side, when the user touches the backside blindfold surface of the operation panel, the operation panel is backlashed. If the operation panel is unstable due to backlash or rattling, or if the operation panel is unstable due to backlash or backlash, it gives the user a kind of discomfort and has this unstable operation panel The quality of electronic equipment is reduced.

Further, even when the operation panel is set in the second operation state in which the back side of the blindfold plate is in front,
If the operation panel moves so as to rattle, there is a possibility that the electronic device main body is easily installed at the back of the operation panel having the blindfold plate surface as the front surface.

In consideration of the above facts, the present invention supports the panel so that it does not move when the panel is set in a predetermined operation state, and holds the panel in a predetermined operation state. It is an object of the present invention to newly provide an electronic device that can easily exhibit a function when set, and that can be manufactured at a low cost with a simple configuration.

[0014]

In the electronic device according to the first aspect of the present invention, a shaft rod is rotatably supported by a panel mounting portion of an apparatus main body, and is rotated to select a front surface or a back surface. A panel to be displayed, a biasing member fixed to a shaft rod of the panel, a biasing operation unit that is a spring member bent to form an inclined surface that is elastically deformable in a part of the biasing member, and a panel. And a starting unit that presses the urging operation unit to stop the panel integrated with the urging member from easily rotating around the shaft bar when the state shifts to a predetermined state.

With this configuration, in this electronic device, when the panel is in a predetermined state in the panel mounting portion of the apparatus main body, the urging operation unit of the urging member is connected to the operation end of the starting unit. It is supported so that it does not move easily when pressed. Therefore, when a predetermined state is set at the panel predetermined position, the panel is prevented from moving in an unstable manner, such as wobbling, and the function when the panel is set to the predetermined operation state can be exhibited well. To improve the user's feeling of use.

Further, since the biasing member for the panel can be constituted by a spring member having a simple shape, it can be manufactured at low cost.

According to a second aspect of the present invention, in the electronic device according to the first aspect, the urging member has a pair of opposing urging operation units, and each of the pair of urging operation units is substantially Formed as a cantilever leaf spring bent in a V-shape, when the panel transitions to a predetermined state, one biasing operation part is an opening formed in a member fixed to the apparatus main body. The panel integral with the urging member is urged to rotate in a predetermined direction around the shaft rod by pressing against one operation end of the activation unit to hold the panel so as not to move easily, or The biasing operation part is simultaneously pressed against each operation end of the starting part, which is an opening formed in a member fixed to the apparatus main body, to stop the shaft from rotating easily. It is characterized by.

With the above-described configuration, in addition to the operation and effect of the first aspect of the present invention, when the panel is shifted to one predetermined state, one of the urging operation sections is activated by the activation section. By pressing against one of the operation ends, the panel integral with the urging member is urged to rotate in a predetermined direction around the shaft bar, and the panel can be held so as not to move easily. Furthermore, when the panel is shifted to another predetermined state, the pair of biasing operation parts simultaneously presses against the respective operation ends of the activation part, respectively, thereby stopping the shaft from being easily rotated, thereby preventing the panel from rotating easily. Can be held so as not to move easily.

Therefore, when the panel shifts to the two predetermined states by the combination of the configuration of the pair of biasing members and the activation portion, each of the panels can be held so as not to move easily. The combination of the configuration of the member and the activation section can exert two stopping actions, which can contribute to simplification of the configuration.

The urging operation portions 102 and 104 of 00 are elastically deformed and slidably pressed against the plane of the support member 58.

In this state, the driven gear 16 is
By 0, no biasing force is applied in the direction of rotation. However, the plane of the support member 58 and each of the urging operation units 102, 104
The operation of the display panel 12 integral with the driven gear 16 such as rattling is reduced by the frictional force between the driven gear 16 and the driven gear 16.

Next, the display panel 12 is rotated in the direction of arrow D, and turned 90 degrees as shown in FIG. (compact disc) or MD
(Mini disc) or the like, so that the recording medium can be loaded or unloaded.

In the loaded state, the urging member 100 rotates integrally with the driven gear 16 that rotationally drives the display panel 12, and one of the urging operation units 104 fits in the starting unit 110. In this state, the oblique side of the tip of the urging operation unit 104 is pressed against the operation end 112 to urge the urging member 100 to rotate in the direction of arrow D.

Thus, the display panel 12 has the shaft 1
A biasing force rotating in the direction of arrow D around the center 5 acts on the driven gear 16 of the drive mechanism for driving the display panel 12 and the sector portion 62 meshing with the driven gear 16, the cam mechanism, or the drive motor 24. The backlash in the gear train, the play for smooth operation, and the backlash are absorbed to prevent the display panel 12 from easily moving.

By rotating the driven gear 16 meshing with the driven gear 16 in the direction of arrow D, the display panel 12 integrated with the driven gear 16 is moved to the position shown in FIG.
14 through the state shown in FIG. 14 to the closed state shown in FIGS. 3 and 15 in the direction of arrow D.

FIGS. 2, 4, 5, 11, and 13
During the operation from the load state to the closed state shown in FIG. 7, the hidden panel 76 pivotally mounted on the display panel 12 has the driven member 80 exiting from the exit of the rotation introducing guide groove 82 and entering the guide part 86, The guide panel 86 guides the hidden panel 76 to rotate about the shaft 78 so as to rise from the end face of the display panel 12 and to insert the insertion port 74 into FIG.
And it is moved to the closed state which closes as shown in FIG.

In this closed state, the urging member 100 rotates integrally with the driven gear 16 for driving the display panel 12 to rotate, and the two urging operation sections 102 and 104 are both fitted in the activation section 110, The urging member 100 is urged to be held at a predetermined position in an immobile state.

For this reason, the display panel 12 has the shaft 1
The urging force for stopping the rotation of 5 acts to stop the display panel 12 from moving easily.

With this configuration, the display panel 12 can be prevented from moving or vibrating in an unstable manner due to a user touching or vibrating in a state where the display panel 12 faces the front side of the blindfold plate. The display panel 12 having a kind of discomfort to the user and further having the front surface of the blind plate.
