IPC: B43L13/00
Filed: 1987-11-30
Abstract: PURPOSE: To enhance writing accuracy by providing means for pressing a pen upward against a position in the way where a shifted pen is brought into a writing region thereby eliminating fluctuation in the height of the pen being gripped by a carriage. CONSTITUTION: When a carriage 7 moves above a pressing means 17 after shifting a pen 8, it is stopped temporarily and the gripping claw 7c of the carriage 7 is released by such extent as the pen 8 can slide up and down. The pen 8 is then moved upward by a distance (d) by the pressing means 17 until the flange part 8a of the pen 8 abuts against the gripping arm 7a of the carriage 7 thus eliminating fluctuation in the height of the pen 8 and keeping a constant height of the pen 8. The gripping claw 7c is closed again under that state and the pen 8 is gripped rigidly before the pen 8 is moved to a writing region. When the height of the pen 8 is corrected in such a manner, writing accuracy can be enhanced.

Title: Paper feeder
Inventor: OGAWA HIROSHI
IPC: B65H3/52
Filed: 1986-12-22
Abstract: PURPOSE:To secure such a paper feeder that is stable in paper conveying performance, by handing a paper separation part and a part feed part with the same part, and installing a paper guide. CONSTITUTION:Paper 22 on a friction plate 19 goes forward to the side of a printer 1 by dint of turning frictional force of a paper feed belt 14. The paper 22 is conveyed by the paper feed belt 14 and fed to the inside of the printer 1 after being separated piece by piece at a ramp 17 for paper separation. A feed paper guide 9 has plural projections 32, and a tip of the paper 22 is moved along the projection 32, whereby a surface of the paper 22 comes into contact with a surface of the feed paper guide 9, thus feed paper resistance is prevented from being varied. Since paper separation and paper feed is carried out by a combination of the paper feed belt 14 and a paper separation base 16, a distance contacting with paper can be made longer as compared with the conventional roller paper feeding system, so that stable paper separation and paper feeding both are performable.
