Title:
【発明の名称】ペ-パ-ム-ビングプロッタのロ-ル紙巻取制御方法
Document Type and Number:
Japanese Patent JP2893220
Kind Code:
B2
Abstract:
Shock or impact forces applied to a paper sheet when the paper sheet is rolled up in a paper-moving type plotter are relieved thereby preventing the paper sheet from being torn or from being displaced from between a pinch roller and a drive roller. While a part of the rolled paper sheet 15 hanging down at a side of the rolling scroll 2, is rolled up due to the rotation of the rolling scroll 2, a load of the drive roller 11 gripping the paper sheet 15 on the platen 1 is monitored by an output of the encoder 20. When a load is applied to the drive roller 11 and rotation of the rolling motor 4 driving the rolling scroll 2 is paused, a part of the rolled paper sheet 15, which part substantially corresponds to the rotation volume due to inertia of the rolling scroll 2, is fed to a side of the rolling scroll 2 by a rotation of the drive roller 11. As a result, no shock or impact is applied to the rolled paper sheet 15 when the rolled paper sheet is wound on the rolling scroll 2.
