PURPOSE:To aim at the automation of a device and improvements in its quality, by installing a luminous intensity sensor, detecting a stain and a hole at every partition of a sheet of split roll paper, and a marker device connected thereto, in a space between a stencil paper roll and a take-up roller as well as in a takeout part. CONSTITUTION:Each sensor part of a luminous intensity sensor unit 20 is connected to each solenoid 25 of each marker device 10 via a control panel 21 respectively. Next, during operation for stencil paper winding, in the case where a stain or a hole is found in part of a sheet of stencil paper P, in time of passing the stain or the hole, luminous intensity varies instantaneously and thereby a sensor part corresponding to a luminous intensity variation part among these sensors monitoring a stencil paper traveling surface detects this variation and a signal thereof is transmitted to the control panel 21. And, at the marker device 10, a marker member 26 rises up as shown by 26' when the solenoid 25 is excited by a signal out of the sensor part, so that its tip end comes into contact with the surface of a long sheet of roll paper 8 and thus can put a mark thereon. |
