The invention concerns a device for the bidirectional displacement of an information support in which one drives alternatively the supplier spool for the rewinding or the receiver spool for the unwinding of the information support by means of mechanical driving means comprising only one motor and in which the inversion of the direction of displacement of the support is obtained through the reversal of the direction of rotation of the motor. The device comprises a frame provided with means intended to receive an information support and receiver and supplier spools; mechanical driving means comprising a motor as well as a member tilting between two positions, the one in which the supplier spool is driven in rotation and the other in which the receiver spool is driven in rotation and in which the inversion of the direction of rotation of the motor causes the movement of this tilting member from one of the said positions into the other.
A device for the bidirectional feeding of an information support having first and second spools about which the support is wound, a reversible motor with a driving shaft, an idle roller, means mounting said idle roller for movement between three positions, said idle roller contacting said driving shaft and said first spool in one of said positions, said idle roller contacting said driving shaft and said second spool in a second of said positions, and said idle roller being out of contact with said driving shaft in the third of said positions, and means for moving said idle roller selectively to any of said three positions.
A device for the bidirectional feeding of an information support having first and second spools about which the support is wound, a reversible motor having a driving shaft, pivotally mounted support means upon which the reversible motor is mounted, and means urging said driving shaft into frictional contact with the first or second spools depending upon the direction of motor rotation, the last-named means comprising a plate, and resilient means yieldably urging an edge of said plate into frictional contact with said driving shaft, whereby rotation of said motor to rotate said driving shaft in one direction causes said driving shaft and motor to move along said edge in one direction until said driving shaft is in frictional contact with one of said spools, and reversal of said motor thereby to rotate said driving shaft in the opposite direction causes said driving shaft and motor to move along said edge in the opposite direction until the driving shaft is in frictional contact with the other of said spools.
A device for the bidirectional feeding of an information support having first and second spools about which the support is wound, a reversible motor having a driving shaft, pivotally mounted support means upon which the reversible motor is mounted, and means urging said driving shaft into contact with the first or second spools depending upon the direction of motor rotation, the last-named means including an inertia wheel on the driving shaft.
