The magnetism erasing ring 13 is wound on the outside of the winding part and the core so that the middle in the width direction agrees with the middle of spacing of the gap in terms of position of magnetic flux direction. The magnetism erasing ring 13 is connected to a frame ground GND through a parallel circuit of a resistor R2 and a capacitor C2.

摘要： PROBLEM TO BE SOLVED: To solve the problem that an ink, which is not dried by simply being left, is normally used for stencil printing so that clogging does not occur by a solidified ink in a plate cylinder even if a long period of time passes from a printing end to the next printing start, but there are some uses in which drying as quick as possible is required depending on uses or papers, and an ink, which is not expensive and has hardening action without using a special device such as an ultraviolet irradiation device or the like, is required. SOLUTION: When a plate cylinder unit using an ink having a quick drying/curing property is mounted, the stencil printing device can recognize it. In the case that a plate cylinder is not scheduled to be reused immediately after a printing, the device monitors a not-in-use time, displays a predetermined warning in a plurality of stages if necessary, and therefore prevents the plate cylinder from becoming unusable due to clogging while storing as much as possible.
