In FIG. 2, the voltage proportional to the moving speed of the printing tape 1 in FIG. It is integrated. On the other hand, the two outputs from the printed matter 2 detected by the photoelectric switches 3 and 4 are logically multiplied by an AND circuit 8, and the logical product output is waveform-shaped into one pulse by a waveform shaping circuit 9. is amplified by relay 11
make it work. When the relay 11 operates, the output from the integrator 7 is discharged to ground in the discharger 12. The integrated voltage from the integrator 7 is compared with the above-mentioned predetermined voltage in a comparator 14 to which a predetermined voltage is inputted from the voltage setting device 13. If the integrated voltage is higher, the comparator 14 indicates a printing deviation. Output 15 is output.
