Abstract
Abstract A coin actuated print control device for operating a conventional electrostatic or bond copy machine, the device having a coin-operated mode and a direct print bypass mode. The device is easily and quickly coupled to a conventional electrostatic or bond copy machine, eliminating complex, electrical modifications of the conventional copy machine circuitry for providing for reliable coin actuated or bypass operation. The control device circuitry includes a power control relay which provides power to a receptacle plug in the device which is connected to the copy machine, a variable time delay circuit to allow warm-up time between coin actuation and print actuation, and a variable print process timing circuit to allow for power process print time (necessary for different copy machines) prior to shut down of the device.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
153 words
A control device for converting a conventional, electrostatic or bond copy machine from a manual print operation to a two-mode device for both coin operation or manual operation, the device comprising: an inlet power source; an electrical plug receptacle for receiving an inlet power line of the conventional copy machine; a coin actuated switch connected to the inlet power source; a power control relay coupled to said coin actuated switch; a print signal actuating circuit connected to a print actuating control switch of the conventional copy machine; time delay circuit means connected between said power control relay and said copy machine print actuating control switch for delaying a signal from the power relay to the print actuating control switch of the conventional copy machine; and a shut down relay connected to said time delay means and said power control relay for shutting off said power control relay after a predetermined amount of time.
Claim 2
Dependent Claim
153 words
A control device for converting a conventional, electrostatic or bond copy machine from a manual print operation to a two-mode device for both coin operation or manual operation, the device comprising: an inlet power source; an electrical plug receptacle for receiving an inlet power line of the conventional copy machine; a coin actuated switch connected to the inlet power source; a power control relay coupled to said coin actuated switch; a print signal actuating circuit connected to a print actuating control switch of the conventional copy machine; time delay circuit means connected between said power control relay and said copy machine print actuating control switch for delaying a signal from the power relay to the print actuating control switch of the conventional copy machine; and a shut down relay connected to said time delay means and said power control relay for shutting off said power control relay after a predetermined amount of time.
Claim 3
Dependent Claim
32 words
A control device, as in claim 1, including: a by-pass switch connected to said coin actuated switch and said power control relay; and a by-pass print switch connected to said by-pass switch.
Claim 4
Dependent Claim
54 words
A control device, as in claim 2, wherein: said time delay means including a warm-up time delay circuit means connected to said power control relay and said copy machine actuating print switch for providing a warm-up delay after power is applied to said copy machine receptacle to delay the actuation of the print switch.
Claim 5
Dependent Claim
49 words
A control device, as in claim 3, including: a process timing circuit connected to said warm-up circuit and said shut down relay, said process timing circuit being variable to allow for printing of a copy in a conventional machine prior to shutting down the power to the copy machine.
