Abstract: A CPU built in a portable telephone (or a PHS terminal), receiving the control signal from a doorway base station, detects the present operation mode. If the present mode is the call enable mode, it is assumed that the user has entered a use inhibit area and the operation mode is changed to any one of the sleep #1 mode and sleep #2 mode previously specified, these two modes belonging to the call inhibit mode. The CPU then performs call incoming control or call originating control. In a case where the present mode is the call inhibit mode when the CPU receives the mode change signal, it is assumed that the user has left the use inhibit area and the operation mode is returned to the standby mode, the call enable mode, and call incoming control and call originating control in the present operation mode are performed.

Abstract: A spelling check apparatus checks a spelling of a word entered from a keyboard, and also displays a word having a spelling similar to the spelling of the input word. The input word is modified by way of plural preselected methods, and when this modified word coincides with a word which has been stored in a word dictionary memory employed in this spelling check apparatus, this modified word is regarded as the similar word. The similar word is displayed every time the modification process for the input word by one preselected method has been accomplished.
