Abstract

PURPOSE:To decrease the number of function keys, by previously calling out a desired one of the function keys which are written into an ROM and providing a key that can be used exclusively for the desired function. CONSTITUTION:A power supply switch 4 is turned on, and a function FK set key 5 is pressed. The number corresponding to the desired FK is supplied as shown by 01, 06, 13 and so on by means of a 10-key block 6. After this, an FK key 7 is depressed. Thus the FK called out of an ROM is designated to an f1 key 7 by an RAM, and the key 7 can be used as the ordinary FK keys sin, arctan, etc. In the same way, either one of 17 FK keys shown in the diagram can be selected and used also for an f2 key 8 and an f3 key 9, respectively. An old FK is erased if a new FK is supplied later, and the supplied FK is erased when the power supply is switched off. In such a way, the number of FK keys can be decreased without decreasing the number of functions FK.
