ABSTRACT:
A low-noise, paper pick or other single cycle mechanism is obtained by employing a rotary solenoid (15) which has a force to a detent position which may be overcome by force from a drive roller (1). In the detent position the drive roller faces a blank sector (5) of a gear (3) which is integral with a shaft (7), which is the shaft to be turned. An electrical control signal to the solenoid rotates gear (3) through gear (13), which is directly driven by the solenoid, and which turns gear (11) on the shaft. The drive gear overcomes the force of the solenoid until it is disengaged after one cycle, at which time the detent force of the solenoid holds the mechanism in its detent position.
