US 4,437,404 A · Electric data recorder

Abstract

An electrically operated data recorder of generally upstanding configuration, bias hinged near the bottom, a gate or side section permitting swinging movement of the hinged section between an open and a closed position. The hinged section serves as a bed of the machine against which a roller platen is designed to act during imprinting of a form from an embossed credit card placed on the bed. The gate is manually moved to the closed position and latched, which energizes an electric motor, setting the roller platen in motion to effect an imprinting operation. When the roller platen reaches the end of the printing stroke, the gate opens, the motor shuts off and is disconnected from driving attachment with the platen moving means. The released roller platen and its moving means are rapidly returned to home position by a spring, and the driving attachment is then reestablished to ready the device for a subsequent operation. In addition, lever means is provided for manually overcoming the latched condition of the gate in case of a jam.

Dependent claims

In a data recorder of the type comprising an upstanding main frame, a roller platen carried on the frame, a fork pivoted on the frame arranged to sweep the platen from a home position horizontally through a substantially erect plane printing path and return, a gate including a bed for carrying a form to receive a printing impression, said gate pivotally mounted to swing between an open loading position and a closed printing position, means biasing the gate towards open position, electric motor means for driving said form to sweep the platen through said printing path including a crank engageable in a slot in the fork for driving the same, and switch means for controlling the energization of said motor, the improvement comprising:

means to cause imprinting of said form by said motor means solely during the printing stroke and to then interrupt the said driving connection between the fork and the motor means;
spring means acting on the fork to restore the same to a location placing the platen in home position once the driving connection is interrupted;
and
means to effect reestablishment of the driving connection in readiness for a subsequent cycle of operation.

In a data recorder of the type comprising an upstanding main frame, a roller platen carried on the frame, a fork pivoted on the frame arranged to sweep the platen from a home position horizontally through a substantially erect plane printing path and return, a gate including a bed for carrying a form to receive a printing impression, said gate pivotally mounted to swing between an open loading position and a closed printing position, means biasing the gate towards open position, electric motor means for driving said fork to sweep the platen through said printing path including a crank engageable in a slot in the fork for driving the same, and switch means for controlling the energization of said motor, the improvement comprising:

the slot in said form having an open end and being so configured that the crank drives the fork in the printing direction only and then allows the crank to escape from the slot as the platen reaches the end of its printing stroke, spring means for moving the fork in a direction to restore the roller platen to home position when the crank has escaped from the slot;
a control bail pivoted on the frame including means for latching the gate in closed position in response to pivoting of the bail in the opposite direction;
means directly responsive to bail motion for closing said switch in response to bail pivoting in said latching direction and for opening said switch in response to bail pivoting in the release direction;
a lateral arm on said fork;
and
means connected with said bail and providing an obstruction in the path of said arm, the position of said obstruction being so callibrated as to cause said arm to pivot said bail to non-latching position as the fork reaches the end of its stroke in the printing direction, thereby substantially simultaneously opening said switch and said gate at the time said fork is restored to home position by said spring means.
