Abstract

PURPOSE:To increase the reliability of read-in, by monitoring the state of delivery of medium, and detecting the slope if the medium has a slope in which the data on the medium is difficult to read in. CONSTITUTION:When the carrying of medium 5 has no slope and the tip of the medium 5 is detected at two detectors almost at the same time, the time difference between the detection signals 201, 202 is slight. When one shot multivibrator 206 detects the trailing of the waveform 201 or 202, a given time of output is produced. At the NAND gate 207, the logical product between the one shot output and the output of inverters 203, 204 is taken, and the Q' output of FF208 is lower with the detection signal 202 which is slower, and no output is produced at the terminal 210. If the medium 5 is carried with a slope, a greater time difference is caused to the detection signals 201 and 202, FF209 is set in the timing of the read-in start signal 212 to obtain the slipe detection signal 210.
