Title: Paper jam detecting mechanism
Inventor: SHIRAKU YUTAKA
IPC: B65H26/02
Filed: 1988-03-15
Abstract: PURPOSE:To detect anything unusual in paper running by comparing a pulse signal outputting by a sensor with a reference pulse signal when detecting a paper feed hole where a line printer is running. CONSTITUTION:A continuous sheet of paper 1 is fed by a paper discharge roller 4 and discharged out of a paper discharge port 2. A sensor consists of a light emitting side sensor 5 and a light receiving side sensor 6, detecting a feed hole 3 for the continuous paper 1. An 'H' signal is outputted to a terminal 20 only when a phototransistor of the light receiving side sensor 6 10 has received infrared light out of LED 8 of the light emitting side sensor 5 run past the feed hole 3. This signal outputs 'H' or 'L' repeatedly according to the presence of the feed hole 3. An interval of this pulse signal is synchronized with a reference pulse signal in advance by a central processing unit(CPU), and with this timing shifted, anything unusual in paper running is detected. In addition, since a paper jam is detectable simultaneously with the occurrence of paper abnormality, paper burning and fuming at a fixing part of a printer can be perfectly prevented from occurring.
