(57) [Summary] [Object] The present invention relates to a front detachment mechanism of an electronic device, and by detaching only the key of the main switch on the front part of the electronic device, the detachment mechanism can be realized with simple parts. It is intended to reduce manufacturing cost and facilitate portability. A key 6 that is detachably attached to a front panel 2 of an electronic device and that turns on a switch 15 of a power supply circuit when attached, and an elastic locking member 13 that locks the key 6 to the front panel 2 are provided. To configure.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a front detachment mechanism of an electronic device, for example, an improvement of a front detachment mechanism of an electronic device, which removes a front portion of a car stereo player or the like to prevent the car from being stolen when it goes out of the vehicle. .

[0002]

[Prior art]

 Conventionally, this type of front detachment mechanism is generally one in which the entire front portion of a car stereo player called a nose piece is attached and detached.

[0003]

[Problems to be solved by the device]

 However, in such a conventional front detachment mechanism, since the nose piece is attached and detached, various parts such as an IC for exclusive use of detachment, a front panel for detachment, a lever, a connector of a spring contact, etc. are required. Not only the number of points is increased and the manufacturing cost is increased, but since the entire front part is carried outside the vehicle, the weight is also large, which is inconvenient to carry.

The present invention has been made in view of such a conventional problem, and a detaching mechanism can be implemented with a simple component by detaching a main switch knob of a front portion of an electronic device. It is an object of the present invention to provide a front detachment mechanism for electronic devices that can be manufactured and can be easily carried while reducing manufacturing costs.

[0005]

[Means for Solving the Problems]

 The present invention is characterized in that it is detachably mounted on a front panel of an electronic device, and has a key for turning on a switch of a power supply circuit when mounted, and an elastic locking member for locking the key to the front panel. It is what

[0006]

In the present invention, when the key is mounted on the front panel, the spring member elastically locks the key to prevent the key from coming off due to vibration, etc., and at the same time, the switch is turned on and the electronic device is powered on and can be used. It becomes the state of. When the key is pulled out against the urging force of the spring member, the spring member is released from the lock, and at the same time the switch is turned off and the electronic device becomes unusable, and the electronic device is detached from the front panel to perform the front detach function. The keys are small and lightweight.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are views showing an embodiment of a front detachment mechanism of an electronic device according to the present invention.

First, the configuration will be described. In FIG. 1, reference numeral 1 is a main body case of an electronic device, 2 is a front panel on the front surface of the main body case 1, the front panel 2 is provided with a display section 3 and a control key 4, and the detachment shown in FIG. The key 6 of the mechanism 5 is detachably attached to the guide hole 7 of the front panel 2. The key 6 is a small and lightweight resin member and is convenient to carry.

In FIG. 2, a guide member 8 forming the guide hole 7 is fixed to the back surface of the front panel 2, and a head 9 of the key 6 is slidably fitted in the guide hole 7. It A shaft 10 is fixed inside the head portion 9, and the shaft 10 is loosely inserted in the circular hole 11 of the guide member 8. A circumferential groove 12 is formed at the tip portion of the shaft 10, and the tip bent portions 13a of a pair of leaf springs 13 are elastically engaged with the circumferential groove 12. The base end of the leaf spring 13 is fitted in the recess 14 on the outside of the guide member 8. The leaf springs 13 may be provided on the left and right sides of the guide member 8, or may be another spring member instead of the leaf spring. Reference numeral 15 denotes a leaf switch attached to the substrate 16, which has contacts 18 and 18 inside the pair of leaves 17 and 17 and a contact portion 19 that contacts the tip of the shaft 10.

Next, the operation will be described. The key 6 is inserted into the guide hole 7, and at the position where the bent portion 13a of the leaf spring 13 is engaged with the circumferential groove 12 of the shaft 10 (the position in FIG. 2), the contact portion 19 of the leaf switch 15 is provided with the shaft 10 of the shaft 10. The tip is hit, the leaf switch 15 is turned on, the power is turned on, and the electronic device is ready for use. The leaf spring 13 is set to such a strength that the key 6 cannot be removed by vibration or the like unless it is manually attached and detached. When detaching the key 6, if the head 9 is pulled out, the leaf spring 13 comes off the circumferential groove 12 of the shaft 10 and can be easily removed. The shaft 10 is separated from the leaf switch 15 and is automatically turned off, so that the electronic device cannot be used. The key 6 is small and lightweight, which makes it extremely convenient to carry.

[0011]

[Effect of device]

 As described above, according to the present invention, by detaching only the key for the power circuit of the front part of the electronic device, the conventional detaching front panel, detaching IC, detaching lever, etc. It is not necessary anymore, the detachment mechanism can be realized with simple parts, the manufacturing cost can be reduced, and the small and lightweight detachable parts make it extremely easy to carry.
