Abstract
PURPOSE: To improve the reliability and to save the arrangement space of keys with regard to a switch unit for control over a paper tape reader, by generating a momentary signal and lock signal with one switch.
CONSTITUTION: With momentary switch 1 depressed for a shorter time than the prescribed time characteristic to monostable multivibrator 6, momentary signal F is generated at the 1st output terminal 7, but since monostable multivibrator 6 is triggered, no output is sent from terminal 15. With momentary switch 1 pushed for a longer time than the prescribed time characteristic to monostable multivibrator 6, momentary signal F is sent from output terminal 7, but FF3 is set later to generate lock signal G at output terminal 15. This signal continues through the latch operation of FF3 even after mometary switch 1 is released from the depression. When momentary switch 1 is pushed again for a short time, lock signal G is reset.
