PURPOSE:To prevent a form from rushing to a cleaner part because of separation defect by providing a displacement detecting shaft interlocked with a separating claw. CONSTITUTION:A device consists essentially of a displacement detecting shaft 12 interlocked with the separating claw and a separation detector 13. Though the front end of the form is brought into contact with a separating claw 11 when the form 10 is attracted to a drum 1 because of separation defect, there are no problems if the form is separated from the drum 1; but if the form passes through the separating claw 11 by some influence while attracted to the drum, the displacement detecting shaft 12 interlocked with the separating claw by the thickness (t) of the form is moved for length t'. The separation detector 13 is provided in this position to which the shaft 12 is moved, and the displacement detecting shaft 12 and the displacement angle t' are set by combination. Though physical oscillation is generated when the front end of the form 10 is brought into contact with the separating claw 11, there are no problems if some time lag is given to a control circuit 14 though the signal from the separation detector 13 is inputted to the control circuit 14. |
