Abstract
Abstract First and second comparing circuits each include respective first and second counter circuits wherein pulses generated by a pulse generator are initially compared by the first comparator with a stored number representing the width of a character to be photographed. In response to an output from the first comparator indicating coincidence with the stored number therein, the second comparator counts pulses from the pulse generator until coincidence with a stored digital factor representing the type size of the character to be photographed. An output signal from the second comparator is fed back to stop the pulse generating device.

Claim 1
Independent Claim
210 words
An automatic feed control device for a photographic typesetter comprising: pulse generating means for generating pulses in response to an input signal; pulse responsive means for receiving said generated pulses; film feeding means controlled in accordance with the number of pulses received by said pulse responsive means for feeding a film; first comparing means including a first counter circuit for counting said generated pulses; first memory means for storing a digital number corresponding to the width of a character to be photographed, a first coincidence detector for generating an output signal when the number of pulses in said first counter circuit and stored pulses in said memory means coincide to reset said first counter circuit; second comparing means including a second counter circuit for counting said generated signals from said first comparing means, second memory means for storing a digital factor representative of the type size to be photographed, and a second coincidence detector for generating an output signal when the number of pulses in said second counter circuit and stored pulses in said second memory device coincide to reset said second counter circuit; and means for feeding back said generated output signal from said second comparing means to said pulse generating device and for stopping said pulse generating device.

An automatic feed control device for a photographic typesetter comprising: pulse generating means for generating pulses in response to an input signal; pulse responsive means for receiving said generated pulses; film feeding means controlled in accordance with the number of pulses received by said pulse responsive means for feeding a film; first comparing means including a first counter circuit for counting said generated pulses; first memory means for storing a digital number corresponding to the width of a character to be photographed, a first coincidence detector for generating an output signal when the number of pulses in said first counter circuit and stored pulses in said memory means coincide to reset said first counter circuit; second comparing means including a second counter circuit for counting said generated signals from said first comparing means, second memory means for storing a digital factor representative of the type size to be photographed, and a second coincidence detector for generating an output signal when the number of pulses in said second counter circuit and stored pulses in said second memory device coincide to reset said second counter circuit; and means for feeding back said generated output signal from said second comparing means to said pulse generating device and for stopping said pulse generating device.
Claim 3
Dependent Claim
61 words
A feed control device as set forth in claim 1, wherein said pulse generating means includes a pulse source, a gate circuit interposed between said pulse source and said first comparing device and for gating the pulses from said pulse source, and a flip-flop circuit for controlling said gate circuit; and said flip-flop circuit is switched by said second output signal.
