Claim:
A portable terminal equipment comprising: a plurality of operation keys each to which a predetermined character and a predetermined function are assigned, and which are provided in an operation section so as to be capable of each being pushed down, each being released from a condition of being pushed down, and each sliding; a display section which displays various information; a touch sensor section which detects each of said operation keys being pushed down and being released from the condition of being pushed down; a moving detecting section which detects each of said operation keys sliding; and a control section which executes said predetermined function assigned to each of said operation keys, when said touch sensor section detects each of said operation keys being pushed down and then detects each of said operation keys being released from the condition of being pushed down, said control section making said predetermined character assigned to each of said operation keys be displayed in said display section, when said moving detecting section detects each of said operation keys sliding while said touch sensor section is detecting each of said operation keys being pushed down, wherein a plurality of characters are assigned to each of said operation keys, said control section making said plurality of characters assigned to each of said operation keys to be displayed sequentially in said display section, every time said moving detecting section detects each of said operation keys sliding while said touch sensor is detecting each of said operation keys being pushed down, after said control section making said plurality of characters assigned to each of said operation keys be displayed sequentially in said display section, every time said moving detecting section detects each of said operation keys sliding while said touch sensor section is detecting each of said operation keys being pushed down, said control section making one of said characters being displayed in said display section at that time be settled, when said touch sensor section detects each of said operation keys being released from the condition of being pushed down, wherein making said predetermined character assigned to each of said operation keys be displayed in said display section is a function, said function being performed only when each of said operation keys is sliding and each of said operation keys is being pushed down, and no part of said function is performed when each of operation keys is just sliding and not being pushed down or each of operation keys is just being pushed and not sliding.
