Title: Integrating circuit of time-limit relay
Inventor: MORI SHIGERU
IPC: H03K17/28
Filed: 1978-02-24
Abstract: PURPOSE: To shorten feedback time and also to make reproduciveness better by procedure in which a discharge circuit consisting of semi-conductor switching elements is directly added to condenser and the charge of the condenser of integrating circuit is discharged promptly and completely.  
     CONSTITUTION: When the input 1 is lower than the voltage of the (+) terminal of the comparator 2 which is determined by the resistance values R 1  and R 2 , the transistors Tr and Tr30 become ON and thus the condenser C is not charged. When the input 1 exceeds the voltage of the (+) terminal of the comparator 2, the transistors Tr and Tr30 become OFF and thus the condenser C is charged. When the voltage exceeds a certain value, the comparator 3 gives off a output. When the input 1 becomes below a predetermined value, the transistors Tr and Tr30 become ON again and the charge of the condenser C is thus discharged promptly through the transistor 30.

Abstract: PURPOSE:To surely carry a small-sized film such as a cabinet in a short time by providing a means detecting the fall of the film on a belt, and driving the belt after the falling is detected and a prescribed time set in advance with film size lapses. CONSTITUTION:The film F finished to be developed and carried out from a film taking out unit is guided in a B-direction at a film feeding position by a guide 23, and falls along the belt 21. At this time, light from a light emitting element 37a constituting a film sensor is interrupted by the film F, and does not reach a light receiving element 37b, so that the fall of the film F can be detected. At this time, a control circuit 40 is delayed for a fixed time by delaying circuit inside and a belt driving signal is outputted. Consequently, a driving circuit 41 drives a belt driving motor 42 and rotates a driving roller 28. Thus, even a small-sized film is surely carried in a short time as much as possible.
