Title: Discrimination data fetching device of character
Inventor: TOOYAMA TERU
IPC: G06V10/10
Filed: 1980-01-21
Abstract: PURPOSE:To make circuit configuration simpler and reliability of character discrimination higher by so constituting a device as to discriminate characters by segmenting characters into one direction, reading them as analog signals and digitizing these analog signals. CONSTITUTION:As a card is run with respect to a magnetic head 3, the analog signals for detecting characters are inputted to an integrating circuit 4 and a monostable multi 5, respectively. The circuit 4 integrates the input signals and outputs the integrated signal to an offset circuit 6 and a holding circuit 7. The monostable multi 5 outputs a pulse to a clock oscillator 8 every time when the signal is inputted. While this pulse is continuous, a sampling pulse oscillator 9 outputs a sampling pulse to the circuit 7 and a discrimination circuit 14. The circuit 7 holds the voltage of the input signal at the point of this sampling pulse. The outputs of the circuits 6, 7 are applied to comparators 10, 11, which in turn apply the signals indicating whether the output of the circuit 4 is of increasing tendency or decreasing tendency to the circuit 14 via FF12, 13. The circuit 14 discriminates the characters of the card by these input signals.

Title: Level detector
Inventor: ISOGAI TOSHIAKI
IPC: G01R19/165
Filed: 1989-01-13
Abstract: PURPOSE:To absorb errors due to a DC voltage in an input signal by connecting an output of detection of an input AC signal to inputs of a capacitor and a variable level shift circuit to compare an output of the level shift circuit with a reference voltage by a comparator circuit. CONSTITUTION:An AC signal V1=VMsinomegat+VA (VM is amplitude of AC component) is applied to an input terminal 1 and a capacitor 11 is charged by a DC signal V2=VM+VA detected and an output thereof is inputted into a variable level shift circuit 14. When a shift voltage of the level shift circuit 14 is represented by VL, Vr=V2-VL=VM+VA-VL is given because an output voltage of the level shift circuit can be detected by a change in an output of a comparator circuit 12 when it is equal to an output voltage Vr of a reference voltage generation circuit 13 and hence, the output voltage is detected with a level VT of an input AC signal expressed by VT=Vr+VL-VA. When a change occurs in the DC component VA of an input signal, the level shift voltage VL also changes to be cancel it. This enables the absorption of a change in the DC component containing the input signal thereby eliminating adjustment of a reference voltage generator.
