2. Description of the Related Art An on-vehicle audio device has an operation member, also called a nose, disposed on the front of the device main body, and various operation buttons, an LCD display element and the like are arranged on the operation surface of the operation member. . Normally, this operating member is fixed to the front surface of the device body by means such as screwing.
As described in Japanese Patent No. 1683, an operation device of an electronic device in which an operation member is detachable from a device main body is also known. According to such an operating device for an electronic device, for example, by removing the operating member from the device main body and holding it during parking or the like, the operation of the internal mechanism and the internal circuit of the device main body left in the automobile is disabled. Therefore, it is possible to prevent the device main body from being stolen from the automobile.

The operating device for an electronic device disclosed in the above publication has a hook and a lock mechanism on the left and right sides on the front of the device body, and the left and right sides of the operating member are connected to the hook and the lock mechanism. Each is configured to be locked. The lock mechanism includes a lock member and an auxiliary member connected via a common shaft, a release button for rotating the lock member, and the like, and the lock member receives a rotational urging force about the axis by a spring. The auxiliary member receives a pushing urging force in front of the apparatus main body and a turning urging force around the axis by another spring.

[0004] In the operation device of the electronic device having such a schematic configuration, when the operation member is mounted on the device body,
After the one end of the operating member is hooked on the hook, and the other end of the operating member is pushed in with the hook as a pivot point, the lock member and the auxiliary member are respectively moved to the other end of the operating member. The operation member can be firmly attached to the device main body. When the operating member is detached from the device main body, when the lock member is rotated by pressing the release button, the lock between the lock member and the operating member is released, but the auxiliary member locks the operating member. Since the operating member is pushed out to the front of the device main body while being maintained, the operating member is rotated by a predetermined angle with the hook portion as a fulcrum, and the other end side of the operating member is in a temporary holding state protruding from the front surface of the device main body by a predetermined amount. When the operating member is grasped by hand and pulled in the temporary holding state, the auxiliary member rotates around the axis and comes off the operating member, and when the operating member is pulled as it is, the auxiliary member comes off the hooking portion. Can be removed from.

[0005]

By the way, according to the above-mentioned prior art, when the operating member is detached from the apparatus main body,
The operating member is projected to the front of the device main body while being locked by the auxiliary member, and the auxiliary member rotates around the axis against the spring force of the spring by grasping and pulling the operating member at this projected position by hand. As a result, the auxiliary member and the operating member need to be securely locked while the operating member protrudes forward of the device main body. For this reason, a large spring force is required for the spring for urging the auxiliary member, and when the operating member is detached from the auxiliary member at the projecting position, it must be pulled with a large force. There was a problem of bad.

[0006]

According to the present invention, the operating member is projected forward of the apparatus main body while being clamped by the clamp bar, and the clamp bar is elastically held at a fixed position by a biasing means. With this configuration, the clamp bar is retracted from the fixed position when the operating member is mounted, and the urging means stores a returning force for pushing the clamp bar to the fixed position. When the lock member that locks the operation member to the device main body is released, the clamp bar is pushed out in the fixed position direction by the accumulation of the urging means. Direction (retraction direction)
Since the tension is applied as a brake, the operating member is stably held at the protruding position while being clamped by the clamp bar, and it is possible to prevent the operating member from dropping off from the clamp bar even when the clamping force is set small. Further, when the operating member is grasped and pulled by hand at the protruding position, the clamp bar and the operating member follow the fixed position forward by a fixed amount while maintaining the clamped state, and the biasing means returns the clamp bar to the fixed position. The return force is stored. Since the clamp between the clamp bar and the operation member is released in the following process, the operation member is accelerated in the pulling-out direction when the clamp is released, and the apparent clamping force can be reduced.
