[Industrial applications]

 The present invention relates to an anti-theft device for an on-vehicle electronic device for preventing theft by removing an operating part.

[0002]

[Prior art]

 In-vehicle electronic devices, especially audio devices, are prone to theft when the user is away from the car, so some kind of antitheft measures must be taken. A common method of preventing theft is to remove the main body of the audio equipment from the car and carry it when the user leaves the car. However, the main body case of the audio equipment is large in size to cover the entire equipment and is heavy, which makes it inconvenient to carry. In addition, since the built-in amplifier of an audio device generates heat, the case of the main unit becomes hot during use. Therefore, it is easy to get burned if the case is removed immediately after use.

Therefore, conventionally, a method of removing only the operation unit of the audio device has been proposed. As shown in FIG. 12, this operation unit is a panel equipped with operation buttons for the audio equipment, and is detachably attached to the main body case of the audio equipment. Therefore, if the user removes the operation part when leaving the vehicle and carries it, the audio device becomes unusable, and it becomes impossible to determine whether the device body is installed in the vehicle from the outside, thus preventing the theft. Can be expected. This operation unit is smaller and lighter than the main unit case, so it is easy to carry. In addition, the operating part is not equipped with a heat generating member such as an amplifier, so no burns will occur if it is removed immediately after use.

Various anti-theft devices for vehicle-mounted electronic devices by such a method for attaching and detaching the operation unit have been proposed in the past. One example is a device provided in a CD player which is an audio device. Will be described with reference to the drawings. When viewed from the front of the body case 1 of the CD player, the vertical direction is vertical, the horizontal direction is horizontal, the front is the front, and the back is the rear. As shown in FIG. 13, the main body case 1 has a rectangular parallelepiped shape, and the portion other than the front surface 1a is embedded in a vehicle dashboard or the like. The front surface 1a is provided with a protruding portion 1b, a plug 2 and a support portion 3. Of these, the protruding portion 1b is a portion in which the upper side of the front surface 1a is protruded in a prismatic shape, and is provided parallel to the upper side of the front surface 1a. A laterally long hole having a size that allows the disc to be inserted and removed in the front and rear direction is provided on the side surface of the projecting portion 1b, and serves as a disc insertion opening 1c. Further, recesses are provided at both ends of the upper surface of the protruding portion 1b to form the engaging hole 1d. The plug 2 is provided below the protruding portion 1b. The rear of the plug 2 is connected to the circuit of the CD player inside the main body case 1. Further, the front of the plug 2 is exposed from the front surface 1a and has elasticity to urge the front. Further, a U-shaped rod-shaped support portion 3 is provided below the plug 2 in parallel to the bottom side of the front surface 1a by fixing both ends thereof to the front surface 1a.

On the other hand, as shown in FIG. 12, the operating portion 4 has a rectangular parallelepiped shape, and a front portion 4 a which is a front side surface thereof is provided with a release button 5, a disc insertion opening 6 and an operating button 7. Of these, the release button 5 is provided above the front portion 4a and is movable in the left-right direction. Below the release button 5, there is provided a horizontally long hole having a size that allows the disc to be taken in and out, and serves as a disc insertion port 6. The disc insertion opening 6 is provided at a position corresponding to the disc insertion opening 1c of the main body case 1. The operation button 7 is a switch for operating the circuit of the CD player, and is provided below the disc insertion slot 6.

Further, as shown in FIG. 14, a pressing roller 8 and a connector 9 are provided on the back surface of the operation section 4. The presser roller 8 is provided above the back surface of the operation unit 4 and moves up and down as the release button 5 slides. The pressing roller 8 is engaged with the engaging hole 1d of the main body case 1. The connector 9 is connected to the rear of the operation button 5 and is exposed from below the rear surface of the operation unit 4. The connector 9 is connected to the plug 2 of the main body case 1. Further, a groove portion 10 is provided on the lower surface of the operation portion 4. The groove portion 10 is engaged with the support portion 3 of the main body case 1.

The operation of the conventional example having the above configuration is as follows. That is, the presser roller 8 engaged with the engaging hole 1d moves up and down according to the slide movement of the release button 5, and therefore when the release button 5 is moved with a finger, the presser roller 8 is pressed as shown in FIG. The roller 8 moves upward and disengages from the engagement hole 1d. Then, the elastic force of the plug 2 pushes the operation portion 4 forward. At this time, since the groove portion 10 on the lower surface of the operation portion 4 is engaged with the support portion 3 of the main body case 1, the operation portion 4 pivots downward with the support portion 3 as a fulcrum, and the plug 2 and the connector 9 are connected.
