IPC: B41J13/00
Filed: 1995-03-29
Abstract: PURPOSE: To reduce the consumption quantity of an ink ribbon while reducing operation cost by unwinding the ink film by the length corresponding to one raw ticket after usual printing is applied to the raw ticket and applying reversal printing to journal paper. CONSTITUTION: At a time of note issuing, at first, a raw ticket is sent out of a hopper 1 to be fed to the gap between a thermal head 7 and a platen by a feed roller 3. At this time, the thermal head 7 is allowed to fall through a cam 6 by the rotation of a motor 20 to bring the raw ticket 2 into close contact with an ink film 25. Next, the rotation of the platen 8 is started by rotating motors 9, 20 and, at the same time, printing is applied to the raw ticket by the thermal head 7 while the ink film 25 is taken up. When the discharge of the raw ticket (customer delivery ticket) 2 is completed, journal paper is sent out of the hopper 21 and the so-called reversal printing wherein the characters printed on the raw ticket 2 by the previous operation are extracted white is performed to discharge the journal paper after printing.

Title: Plastic continuous rolling mill
Inventor: AOSHIMA ATSUSHI
IPC: B29C55/00
Filed: 1984-04-11
Abstract: PURPOSE:To restrain generation of voids resulting from rolling by providing on a pressure vessel a delivery port for a long rolled plastic which is s constituted as to be freely adjustable according to the cross-section form and size of the plastic passing through the delivery port. CONSTITUTION:A delivery port for a long rolled plastic provided on a pressure vessel 1 is so constituted that it is freely adjustable according to the cross-section form and size of the plastic passing through the delivery port. That is, the constitution is such that although the delivery port for a long rolled plastic accommodates the cross- section form and size of a long rolled plastic passing through the delivery port as is the case with a feeding port, the delivery port is freely adjustable so as to meet the cross-section form and size of the plastic which are different from the original ones because it is rolled in a sealed vessel. The form and size of the delivery port after adjustment shall eliminate substantial leakage of a pressurized fluid in the vessel while allowing the long rolled plastic to pass through the delivery port smoothly because of its low friction resistance or permit leakage or outflow of the pressurized fluid in a small quantity. For instance, the delivery port shall be similar to the cross-section form of the long rolled plastic and wide than the circumference of the plastic by approx. 0.000005-2.0mm. of clearance.
