Abstract

PURPOSE: To provide a paper conveyance detection circuit of low cost and high accuracy, the number of times of testing and adjustment of which at the starting of a paper conveyor is greatly reduced, by using an analog-digital converter and a nonvolatile memory.
CONSTITUTION: At the starting of a paper conveyor, a desired sensor is selected by a multiplexer 5 and the digital value of the signal of the sensor is applied to a shift register 2. An instructed slice value in a register file 6 set through a register 4b is set in a comparator circuit 3 by a microprocessor. Said instructed slice value and the digital value in the shift register 2 are compared with each other. The result of the comparison is written in an external register 4a.
