摘要

An electronic device has an operating section (11) having a plurality of input keys (12). The operating section is detachably connected to a body (1) of the device in such a manner that the contacts of the operating section are electrically connected to the contacts of the body when the operating section is connected to the body. The body includes a connection detecting section (2) for detecting the connection of the operating section to the body to output a connection detection signal. A control section (3,5) makes the connection of the contacts of the body and of the operating section effective a predetermined period of time after provision of the connection detection signal.
