DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-vehicle electronic device for driving an operation panel, and more particularly, to a vehicular in-vehicle electronic device which is useful for hiding the in-vehicle electronic device when a user leaves the vehicle to prevent theft. The present invention relates to a device anti-theft device.

[0002]

2. Description of the Related Art There is known a device for hiding electronic devices mounted on a vehicle to prevent theft when the user leaves the vehicle. FIGS. 3 and 4 show an example of an anti-theft device for in-vehicle electronic devices proposed by the present applicant in Japanese Patent Application No. 6-339875.
Shown in In the figure, reference numeral 104 denotes a chassis for accommodating on-vehicle audio equipment, which is inserted and mounted in a mounting recess of a car. The escutcheon 106 is fixed to the chassis 104 and rotatably supports the frame 107.

FIG. 3A shows a state of use of an on-vehicle audio device, and an operation panel 108 is located in front.
Reference numeral 108a denotes a cassette insertion port provided on the operation panel 108. When the start switch of the anti-theft device is pressed in the state shown in FIG.
The frame 107 is rotated to the horizontal position as shown in FIG. In this state, the cover 105 is moved from a position above the inside of the chassis 104 into a groove provided inside the frame 107. At the same time, the operation panel 108 is moved backward. FIG. 4A shows a state in which the cover 105 and the operation panel 108 have moved.

Next, as shown in FIGS. 4 (b) and 4 (c), the frame 107 is rotated to the original vertical position.
In this state, the cover 105 covers the operation panel 108, so that the in-vehicle audio device cannot be seen and theft is prevented. The operation opposite to the above is performed to bring the on-vehicle audio device into a use state.

[0005]

However, the above-mentioned conventional anti-theft device for in-vehicle electronic equipment has a problem that a driving mechanism for moving the operation panel 108 horizontally becomes complicated. Further, a space for horizontally moving the operation panel 108 is required, and the space utilization efficiency is poor. In addition, the operation panel 108 is separated from the playing device, and it is necessary to devise a mechanism for inserting and discharging a disk, a cassette tape, and the like. There is a problem that the mechanism becomes complicated and the cost increases.

The present invention has been made in view of the above points, and has as its object to simplify a drive mechanism by rotating an operation panel, and to insert and discharge a disk or a cassette tape. It is an object of the present invention to provide a device for preventing theft of an in-vehicle electronic device, which can simplify a mechanism for inserting and discharging a disk, a cassette tape, and the like by reducing a stroke for the electronic device.

[0007]

According to the present invention, there is provided an electronic apparatus comprising:
An operation panel disposed in front of the device and rotatably supported by a rotation shaft provided on a chassis; and a closed position disposed on a front surface of the operation panel and covering a front surface of the operation panel, and at least the operation panel. A cover whose one end is exposed to the outside and is supported at a position above the operation panel so as to be able to move back and forth and rotatably so as to take an open posture accommodated in the housing; When transitioning from the state to the non-use state, the operation panel is turned from the first state in which at least a part thereof protrudes outside the housing of the device to a second state housed inside the housing. The cover is configured to change from the open position to the closed position after the operation panel is in the second state.

The electronic device according to the present invention is the electronic device, wherein the operation panel is inclined upward in the first state.

In such a configuration, the operation panel only needs to be rotated, and the driving mechanism is simplified. In addition, the moving distance of the insertion opening for a disk, cassette tape, or the like can be reduced, and the stroke for insertion and ejection can be reduced. In use, since the operation panel is inclined upward, the operation becomes easy.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an anti-theft device for a vehicle-mounted audio device according to an embodiment of the present invention. FIG.
1 is a perspective view showing an appearance of an antitheft device for an in-vehicle audio device according to an embodiment of the present invention. The audio equipment main body is housed in a chassis 5 to which an escutcheon 3 for mounting a car is fixed in front, and an operation panel 1 is rotatably supported in a frame of the escutcheon 3. The cover 2 is moved between a position covering the front surface of the operation panel 1 and a position hidden in the chassis 5.

FIG. 1A shows a state of use of a vehicle-mounted acoustic device. At this time, the operation panel 1 is inclined so as to face upward, and the cassette is inserted from the cassette insertion opening 1a provided in the operation panel 1 and guided by the cassette guide 4 fixed to the mechanism chassis to be drawn into the audio equipment main body. It is.
FIG. 1B shows a state in the transition from the use state to the non-use state, and FIG. 1C shows the non-use state. When not in use, first, the operation panel 1 is set in the upright state as shown in FIG. 1B, and then the cover 2 is placed at a position covering the front surface of the operation panel 1 as shown in FIG. Move.

FIG. 2 shows a drive mechanism of the operation panel 1 and the cover 2. FIGS. 2A, 2B, and 2C correspond to the states shown in FIGS. 1A, 1B, and 1C, respectively. The cover driving member 7 shown in the figure is slidably supported by a shaft 7b erected on the mechanism chassis, and the gear 6 rotatably supported by the mechanism chassis and the rack 7a of the cover driving member 7 mesh with each other. I have. A hook 7c provided at the tip of the cover driving member 7 locks one end of the cover 2.

The operation panel driving member 9 is slidably supported by a shaft 9b provided upright on the mechanism chassis. A gear 8 rotatably supported by the mechanism chassis and a rack 9a of the operation panel driving member 9 mesh with each other. ing. The tip of the operation panel driving member 9 is rotatably connected to a lower portion of the operation panel 1 by a pin. The upper portion of the operation panel 1 is rotatably supported by a shaft 1b erected on a mechanism chassis.

When shifting from the use state to the non-use state shown in FIG. 2A, first, the gear 8 is rotated counterclockwise by a drive mechanism (not shown). The operation panel driving member 9 moves rightward, and the operation panel 1 is in an upright state as shown in FIG. Next, the gear 6 is rotated counterclockwise by a drive mechanism (not shown). The cover driving member 7 moves to the left, the cover 2 is sent to the left (forward), and rotates downward by its own weight to cover the operation panel 1 as shown in FIG. Since the audio equipment is hidden when not in use, theft is prevented. In the use state, the operation panel 1 is inclined upward, so that the operation is easy. Even if the operation panel 1 rotates, the operation panel 1 is
The distance (t shown in FIG. 2A) projecting rearward is smaller and the movement stroke of the cassette is smaller. Therefore, the cassette tape insertion / ejection mechanism can be simply configured. Note that the operation panel 1 may be covered after the cover 2 is accommodated in a frame as in the configuration of Japanese Patent Application No. 6-339875.

[0015]

According to the anti-theft device for in-vehicle electronic equipment of the present invention, the operation panel simply rotates, and the driving mechanism of the operation panel is simplified. In the use state, the operation panel is inclined upward, so that it is easy to operate.

Further, by reducing the stroke for inserting / ejecting a disk, a cassette tape, or the like, the mechanism for inserting / ejecting a disk, a cassette tape, or the like can be simplified.
