Control system of coin-operated locker

A control system of a coin-operated locker which comprises:

• a time-lapse detecting section for producing a time-lapse output signal whenever a predetermined unitary period of time has passed starting from the time instant when said locker is used;
• b. a control section for producing a control signal by receiving, as input condition signals, the time lapse output signal from said time-lapse detecting section, and a signal generated by operating a key of a lock provided on said locker;
• c. a stepping drive mechanism which under the control of said control section is driven by stepping drive means to advance stepwise in one direction when said lock is unlocked and when an overtime fee charging operation is effected, and to advance stepwise in the opposite direction when a coin is inserted into said locker;
• and
• d. means for stopping, when said stepping drive mechanism is advanced stepwise in the one direction during said overtime fee charging operation, the operation of an opposite direction stepping drive section relating to the drive of said stepping drive mechanism in the opposite direction, so as to continue the drive of said stepping drive mechanism in the one direction.
