  Next, the operation of the electronic device according to the first embodiment will be described.

(1) When the operation display device 2 is fixed to the device body 1

  When the operation display device 2 is fixed to the device main body 1, the operation display device 2 functions as a user interface of the device main body 1 while being connected to the device main body 1.

  The controller 25 of the operation display device 2 receives a request from the main controller 15 via the communication circuits 16 and 26 and displays an operation screen corresponding to the request on the display device 21. When a user operation on the operation screen is detected by the input device 22, the controller 25 transmits the operation information to the main controller 15 via the communication circuits 16 and 26. The main controller 15 executes processing according to the operation information.

For example, in the case of an organic EL (Electro-Luminescence) display, the pixel emits light, so that the amount of light output from the display device 21 is increased by displaying white over the entire area without displaying objects such as images and characters.

  Thereafter, the operation display device 2 continuously operates as an emergency light (step S4).

  As described above, when the user removes the operation display device 2 from the device main body 1, the operation mode of the operation display device 2 shifts to the emergency mode, and the power stored in the power storage unit 24 is changed to each unit in the operation display device 2. The operation display device 2 operates as an emergency light using the display device 21 as a light source. Then, the user can carry the removed operation display device 2 and use it as an emergency light.

  After that, when the user fixes the operation display device 2 to the device main body 1, the attachment / detachment detection unit 27 detects that the operation display device 2 is fixed to the device main body 1 and notifies the controller 25. At that time, the controller 25 operates the operation display device 2 as the user interface of the apparatus main body 1 as described above when there is power supply from the apparatus main body 1 and when there is no power supply from the apparatus main body 1. Shuts down the operation display device 2.

  As described above, according to the first embodiment, the operation display device 2 can be attached to and detached from the device main body 1, and the controller 25 of the operation display device 2 is used for controlling the device main body 1 at normal times. The operation screen is displayed on the display device 21, user operation information for the operation screen detected by the input device 22 is transmitted to the device main body 1, and it is detected that the operation display device 2 has been detached from the device main body 1. Immediately after being detected by the unit 27, the amount of light emitted from the display device 21 is increased using the power stored in the power storage unit 24.

  Thus, when the operation display device 2 is removed from the apparatus main body 1 by the user, the operation display device 2 can be used as an emergency light, and the emergency light can be provided to the user.
