  FIG. 20 is a flowchart for explaining a second embodiment of the control by the computer 1.

  The EC / KBC 106 confirms the state of the connection detection unit 49 (step S200).

  When the EC / KBC 106 determines that the state of the connection detection unit 49 is the “connection detection state” in which it is detected that the main body 11 and the waterproof case 50 are connected (Yes in step S200), the EC / KBC 106 Instructs the CPU 100 to lower the value of the frequency of the clock signal used by the CPU 100 itself (step S201).

  The CPU 100 decreases the frequency value of the clock signal used by the CPU 100 in accordance with the instruction from the EC / KBC 106 (step S202).

  When the waterproof case 50 is attached to the main body 11, the intake hole portion and the exhaust hole portion are blocked by the waterproof case 50, so that the FAN 48 cannot function. Therefore, by reducing the frequency value of the clock signal of the CPU 100, it is possible to reduce the heat generated by the CPU 100 and adapt the CPU 100 to a natural air cooling state in which the FAN 48 is not driven.

  In the embodiment described with reference to FIGS. 19 and 20, when the EC / KBC 106 detects that the waterproof case 50 is connected to the main body 11, the rotation of the FAN 48 is stopped or the CPU 100 is used. However, the present invention is not limited to this configuration, and it is detected by the EC / KBC 106 that the waterproof case 50 is connected to the main body 11 and detected by the temperature sensor 100a. When the CPU 100 reaches a predetermined temperature, the rotation of the FAN 48 may be stopped, or the frequency value of the clock signal used by the CPU 100 may be lowered.

  The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
