PURPOSE:To attain cooling by means of a cooling fan and the OFF operation of a power supply switch to easily execute cooling operation and power OFF operation by arranging a data transmitter on a prescribed position of a cooling tray. CONSTITUTION:A switch operation hole 11 is formed on a heat insulating case 4 for the data transmitter 3 and a blocking piece 12 consisting of a heat resisting material to be used also for the operation chip of the power supply switch 10 is elastically connected to an inside aperture. On the other hand, the cooling tray 13 on which the data transmitter 3 is to be mounted is fixed to a data receiver 7 and the mounting of the data transmitter 3 is detected by a sensor 15. The cooling fan 16 fixed to the side of the data receiver 7 is automatically driven to forcedly cool the data transmitter 3, and when an operating projection 14 is inserted into the operation hole 11, the power supply switch 10 is turned off through the blocking piece 12. Consequently, the cooling operation and the power OFF operation can easily be executed. |
