2. Description of the Related Art In recent years, in-vehicle audio equipment has been upgraded and multifunctional. For this reason, theft accidents frequently occur, which is a problem. To cope with this problem, there has been proposed an audio device having anti-theft measures. For example, an in-vehicle acoustic device including a device main body fixed to a vehicle and an operation unit detachably attached to the device main body has been receiving high demand.

[0003] In such an acoustic device, when the user leaves the vehicle, the operation unit can be detached from the device body and carried. That is, once the operation unit is removed from the device main body, the device main body can be made inoperable. As a result, theft accidents are suppressed.
Moreover, if the operation unit is removed, it cannot be determined from the appearance whether or not the device main body is installed in the vehicle. Therefore, there is no possibility that only the main body of the device is subjected to the theft accident.

[0004] The above-mentioned on-vehicle audio equipment has an anti-theft effect by carrying an operation unit. That is, removal of the operation unit is a prerequisite for securing the anti-theft effect. Therefore, it is necessary that the operation of removing the operation unit be simple. In general, strong vibrations are applied to the on-vehicle audio equipment due to running of the vehicle or the like, so that the operation unit must be firmly attached to the main body of the equipment. That is, an on-vehicle audio device in which an operation unit is detachably attached to a device main body is required to have a simple operation of attaching and detaching the operation unit and a strong attachment force of the operation unit to the device main body.

[0005] In order to satisfy such demands, conventionally, an operation unit attaching / detaching device as shown in FIGS. 13 and 14 has been proposed. The in-vehicle acoustic device to which the operation unit attaching / detaching device is used is a CD player, and includes a device main body 1 and an operation unit 2 for operating the same. The device body 1 is fixed to a console or the like on the vehicle side. The device body 1 is a horizontally long front 1
a, where a support portion (not shown) for supporting the operation portion 2 is provided.

The operation unit 2 is a substantially rectangular parallelepiped member having a horizontally long front and back surfaces. The front and back of the operation unit 2 are set slightly larger than the front of the device body 1. The front of the operation unit 2 is provided with an operation button, a CD insertion slot, a display unit, and the like. A release button 3 that is movable in the left-right direction is provided on the upper edge of the front surface of the operation unit 2.

Further, a lock release mechanism (not shown) is provided inside the operation unit 2. When the front surface of the device body 1 and the back surface of the operation unit 2 come into contact with each other, the lock release mechanism engages with the device body 1 to perform a locking operation for fixing the operation unit 2 to the device body 1, and a release button. When the device 3 operates, a release operation for releasing the lock operation is performed. The lock release mechanism performs the lock operation when
At least the vicinity of both ends of the front surface 1a of the device main body 1 is engaged.

In the operation section attaching / detaching apparatus having the above structure, when the operation section 2 is fixed to the apparatus main body 1, the operation section 2 is attached to a support section (not shown) of the front surface 1a, and
The back surface of the operation unit 2 is brought into contact with the front surface of. At this time, the operation unit 2 is fixed to the device main body 1 by the lock release mechanism performing the locking operation. At this time, since the lock release mechanism is engaged at least near both ends of the front surface 1a of the device main body 1, the operation unit 2 can be fixed to the device main body 1 with a strong mounting force.

When the operation unit 2 is detached from the main body 1, the lock release mechanism performs a release operation by sliding the release button 3. As a result, the operation unit 2 is disengaged from the device main body 1, and the operation unit 2 can be detached from the device main body 1. Then, the operation unit 2 is detached from the device main body 1 so that the operation unit 2 is pulled out. As described above, according to the operation unit attaching / detaching device, the operation of detaching the operation unit 2 from the device main body 1 can be performed only by performing the sliding operation of the release button 3.

[0010]

The above-mentioned lock release mechanism is configured to engage at least near both ends of the front surface 1a of the main body 1 in order to obtain a strong mounting force. Therefore, a member that covers the entire area of the operation unit 2 in the left-right direction is indispensable for the lock release mechanism. As a result, the constituent members of the lock release mechanism have become large, and the manufacturing cost of the operation unit attaching / detaching device has increased.

Further, since the lock release mechanism is provided in the operation section 2, the operation section 2 becomes considerably large. Even so, there is a strong tendency that the size of the operation unit 2 is increased due to the multifunctionality of the audio equipment. When the operation unit 2 becomes large, it becomes bulky and obstructive when it is removed from the device body 1 and carried. When the operation unit 2 is in the way, it is troublesome for the user to remove the operation unit 2 from the device main body 1. As described above, since the removal of the operation unit 2 is a prerequisite for securing the anti-theft effect, the deterioration of the portability of the operation unit 2 leads to a decrease in the anti-theft effect.

As described above, in the conventional operation unit attaching / detaching device, an increase in manufacturing cost due to an increase in the size of the device causes an increase in manufacturing cost.
Deterioration of portability of the operation unit has been a problem. The present invention
It is proposed to solve such a problem,
It is an object of the present invention to provide an operation unit attaching / detaching device that reduces manufacturing costs by downsizing the device and enhances portability of the operation unit by downsizing the operation unit to ensure an excellent anti-theft effect.
