Abstract

PURPOSE:To make adjustment possible easily independently of the amplification charactertistic of a tape deck, by measuring the time width of a shaped pulse waveform in the cash register side to decide and display whether the reproducing level in the tape deck side is proper or not. CONSTITUTION:The deck side signal is caused to pass through cable 5 and is amplified by amplifier 7 of electronic apparatus 3 and is rectified and integrated by integrating equipment 8, thereby obtaining a square wave in waveform shaping circuit 9. The pulse time width of this wave is measured by measuring circuit 10. Decision circuit 11 compares time width T of the measured pulse with a set value and outputs true value 1 and true value 1 to output end d1 and output end d2 respectively for larger time width T and smaller time width T respectively. Signal H passes through AND gate 14 to display signal H indicating an excessive level on display part 16, and signal e2 at output end d2 passes through AND gate 15 to display M indicating a proper level on display part 16. Reproducing level detection circuit 17 detects a level lower than a prescribed value to inhibit the operation of circuit 11, and simultaneously, circuit 17 sends a signal indicating a too-small level through AND gate 19 to display L on the display part.
