Control the operation of at least a portion. In a state where the operation unit is attached to the electronic device body, the connectors respectively provided in the electronic device body and the operation unit are fitted to each other and electrically connected, and the control becomes possible. In such an electronic device, when the operating portion is removed from the electronic device main body, since the respective connectors are exposed to the outside, at least the operating portion is provided with a door capable of covering the connector.

With this door, when a user walks around the operation section, dust entering from the connector or the peripheral portion of the connector,
It protects the operating unit from adverse effects by blocking dirt and static electricity.

When the operating section is attached to the main body of the electronic device, the door is attached to the position where the connector is opened, and after the operating section is removed from the main body of the electronic device, the door is attached to the position where the connector is covered. To be

Therefore, it is easy to handle and highly convenient, and it is possible to surely protect the operating portion from the adverse effect.

Preferably, the door is mounted so as to be slidably displaced in a direction intersecting the fitting direction of the connector. The door is slid and displaced to a position where the connector is opened when the operation unit is attached to the electronic device body, and is also slid and displaced to a position where the connector is covered after the operation unit is removed from the electronic device body. .

Therefore, the user can protect the operation section by a simple operation.

Further preferably, the electronic device main body is
A pressing piece is erected upright to face the operation portion, and the operation portion is provided with an elastic member that elastically biases the door in the direction to cover the connector. A guide slope is formed on at least one of the door and the tip of the pressing piece so that the door and the tip of the pressing piece are in sliding contact with each other.

When the operating section is attached to the electronic equipment body,
When the pressing piece presses the guide slope of the door, the direction of the pressing force is converted from the direction parallel to the fitting direction of the connector to the intersecting direction. By this converted force in the cross direction,
The door is pressed against the spring in the opening direction of the door and guided to the position where the connector is opened. When the operation unit is removed from the electronic device body, the elastic member elastically repels the door to the closed position, thereby covering the connector.

Therefore, the user can open and close the connector only by attaching / detaching the operation unit to / from the main body of the electronic device, and the operability can be further improved.

The doors 76 and 77 are respectively supported against the resilience of 0 and 81, and the open state is maintained.

The connector 75 exposed by this
Can be connected to the connector 92. The connection connector 92 is fitted into the connection connector 75 through the window 89,
The operation unit 72 and the electronic device body 71 are electrically connected, and the electronic device 70 can be used.

The operation of the door when the operation portion 72 is removed from the electronic equipment body 71 will be described below. When the operation portion 72 is pulled out, the fitted connecting connectors 75 and 92 are separated from each other. Further, the pressing pieces 94 and 95 slip out of the support holes 96 and 97, and as a result, the doors 76 and 77 that have lost their supporting force.
Are pressed in directions close to each other by the elastic force of the winding springs 80 and 81. The pressed doors 76 and 77 are guided to the closed position by sliding between the pressing pieces 94 and 95 and the guide slopes 82 and 83. Therefore, the doors 76 and 77 are in the closed state, and even if the user walks around the operating section 72, the operating section connecting connector 75 is protected from adverse effects.

In the electronic device 70 having the above-described structure, the user's operation for opening and closing the doors 76 and 77 is unnecessary,
Further, convenience can be improved.

[0040]

As described above, according to the present invention, the operation unit for controlling the operation of at least a part of the main body of the electronic device is provided in the electronic device detachable from the main unit of the electronic device to prevent theft and the like. Since a door is provided to cover at least the operation unit side of the connector that electrically connects to the electronic device main body to prevent dust, the user only has to open or close the door depending on whether or not to use the operation unit. Well, as it does not require a separate structure for dust protection such as the conventional protective case, it eliminates the inconvenience of storing the protective case and putting the operating part in and out of the protective case, improving convenience. can do.

Preferably, since the door is provided so as to be slidably displaced from the position where the connector is covered to the position where it is opened,
You can open and close the door with a simple operation.
