Abstract

PURPOSE:To perform an accurate operation without malfunction, by constructing a sheet and a mode in which memory contents can be rewritten freely to correlate to each other in 1:1. CONSTITUTION:In case of mode switching, the knob of mode change-over switch 7 is returned to the most left end to release the set of the current mode. Sheets are so selected that sheet 9c of the mode to be set newly becomes the top page; and when mode change-over switch 7 is released from fingers, it moves to the right automatically and is brought into contact with notch part 9c' of sheet 9c to set the mode. Consequently, an accurate operation without malfunctions is possible by depressing key top 5 dependently upon memory contents written on sheet 9c.
