Japanese Patent JPS5149208
Kind Code:
B2
Abstract:
A device for moving an information card, microfiche, or the like, including a reversible drive shaft, a clutch associated therewith, solenoid-operated means for controlling the clutch to produce a predetermined angular increment of output rotation from the clutch each time the solenoid is energized, and a set of gears for transmitting drive from the clutch to an output shaft that is connectable to move an information card. The clutch comprises a toothed wheel connected to the drive shaft, a separately rotatable disk, and a pair of arms pivotally mounted on the disk for engaging the toothed wheel to drivingly connect the drive shaft to the disk. The clutch-controlling means comprises a pair of levers respectively engageable with the clutch arms, and movable by the solenoid to cause movement of the arms into and out of operation engagement with the teeth of the wheel. The transmitting gears include a first gear connected to the disk, a sun gear connected to the output shaft, and a planet gear meshing with the first gear and sun gear and mounted so as to be movable about the sun gear when the first gear is stationary to effect minor angular displacement of the output shaft for fine adjustment of the position of the information card.
