Abstract

PURPOSE: To make it possible to discriminate easily needed input keys by selectively displaying only titles of needed input keys by functions on a key title liquid-crysatl display unit by a driving signal from CPU.
CONSTITUTION: Fixed clocking operation is performed by CPU11 and on the basis of the operation, fixed display driving signals and driving signals X, Y and Z driving signals are supplied to output information liquid-crystal unit 2 to display the time. Furter, driving signal X is supplied from CPU11 to key title liquid-crystal display unit 5 and at the timing of driving signal X, a display driving signal is also supplied, thereby displaying key title CAL of input key 45. This key is operated to set a computer mode and each key title is displayed on unit 5 by driving signal Y from CPU11. Consequently, only titles of needed input keys are selectively displayed by functions, so that needed input keys can easily be discriminated.
