In such a car audio device having a removable front panel, adjustment of electronic components built in the main body side is performed by removing the front panel and operating an operation member arranged on a sub panel on the main body side. For example, if the microcomputer built into the main unit malfunctions due to static electricity during use, it is necessary to reset it urgently.Therefore, there is a reset switch on the sub panel of the main unit. When a malfunction occurs, the front panel is removed and the sub-panel is exposed to operate the reset switch.

Since this reset switch is extremely small and cannot be directly operated with fingers due to the arrangement space and the like, it has been operated with a pin-shaped operation jig.

[0005]

As described above, an operation jig is required to operate a very small part such as a reset switch of a car audio device, but it is used for operation by predicting a situation such as a malfunction from the beginning. There is almost no possibility that a jig will be prepared, and therefore, there is a problem in that it is not possible to immediately perform a reset operation when an emergency reset operation is required.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an electronic apparatus such as a car audio device in which an operating jig can be stored and held in the vicinity of an operating portion.

[0007]

In order to achieve the above object, the present invention relates to an electronic device in which a front panel can be attached to and detached from the device body, for operating the device body side at a required portion of the front panel. The jig is configured to be stored and held.

This operating jig is preferably stored and held on the back side of the front panel.

Further, it is preferable that the accommodating and holding portion of the operating jig is formed by a concave portion.

[0010]

[Function] By storing and holding the operation jig in the required portion of the front panel, for example, when performing an operation such as an emergency reset of the reset switch on the equipment main body side, it is necessary to search for the operation jig or a jig that replaces it. Instead, by removing the front panel, the operation jig can be taken out and quickly operated.
