PURPOSE:To prevent securely the equipment from being left powered on forgetfully when it is not used by projecting a switch operation part in an earphone storage part and operating a switch with an earphone. CONSTITUTION:The earphone 12 is pressed against the operation part 32 of the leaf switch 31 while the earphone 12 is stored in the earphone storage part 11, and its contact 34 is set in its off state. When a lid 29 is opened and the earphone 12 is taken out of the storage part 11, the pressing force of the earphone 12 is removed from the operation part 32 and the contact 34 is made. Therefore, when the switch 31 is turned off, the power source is turned on and off automatically by taking the earphone out and storing it. Thus, the equipment is prevented securely from being left powered on forgetfully when not used. |
