Title: Double-feed error detector of printing machine
Inventor: TAKAHASHI SATOSHI
IPC: B65H7/12
Filed: 1984-08-17
Abstract: PURPOSE:To always detect a double-feed error correctly computing the average value of light transmission quantity of normally fed printing paper and tolerance determined from the average value, and deciding to be a double-feed error when the light transmission quantity of paper exceeds the tolerance. CONSTITUTION:When a printing machine is operated, according to a paper feed detection signal (s) from a comparator 2 to which an output signal of a photoelectric sensor 1 is input, a microcomputer 6 decides whether it is under paper feed operation or not, and during detection of paper feed, a detection voltage (x) from A/D converter 3 is input to the microcomputer. Modification data Xa is creased by subtracting a fixed value (a) from the detection voltage (x). Subsequently, the average value (x0) of output signals of the photoelectric sensor 1 and tolerance epsilon determined from the average value (x0) are computed, and then it is decided whether a difference between the average value (x0) and the modification data Xa is smaller than the tolerance epsilon. If no, it is decided to be a double-feed error. When a double-feed error is decided, a tape inserter 8 is driven to insert a tape as a mark, and an alarm device 9 is operated.

Filed: 1980-12-06
Abstract: PURPOSE:To facilitate control over the absorption of longitudinal vibration of a tape and to apply the best DC tension to the tape simultaneously with and independently of the said control, by detecting the tape tension. CONSTITUTION:The output signal 53 of a tape tension detector TD using, for example, an optical slit plate is amplified 32 and then supplied to a differentiating circuit 33 and a low-pass filter 36.
