Title: Printer
Inventor: SASAKI TOSHIYUKI
IPC: B41J11/00
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To propose a paper feeding mechanism capable of providing an accurate paper feeding pitch without generating jamming of a recording paper in a printer having a plurality of paper feeding rollers. SOLUTION: Since a sub paper feeding roller mechanism 13 of a printer is provided capable of being opened or closed by comprising a roller opening and closing mechanism 20, and the distance of conveying a slip paper by a main paper feeding roller mechanism 12 and the sub paper feeding roller mechanism 13 simultaneously, slackening of the slip paper due to difference of the paper feeding amounts is not generated, and thus jamming can be prevented. Moreover, since a sub paper feeding roller 13a comprises a brake mechanism for providing a constant load, a wheel row can be maintained in the state without a backlash, and thus the paper feeding pitch cannot be disturbed from immediately after the contact of the sub paper feeding roller mechanism 13.  Furthermore, the brake mechanism prevents the paper feeding pitch disturbance due to the impact at the time the roller opening and closing mechanism is operated. Besides, since the lateral direction rattle of the sub paper feeding roller 13a is always forced to one side, printing disturbance caused by lateral movement of a slip paper 5 for the rattle of the sub paper feeding roller mechanism 13 can be prevented.

Filed: 1988-06-29
Abstract: PURPOSE:To prevent the wasteful use of a cut paper by reducing picture data by matching to the size of the cut paper when the size of the picture data is larger than the cut paper in a prescribed range. CONSTITUTION:The coding picture data stored in a code data memory 5 are decoded by a coding decoding circuit 7 and the decoding picture data are stored into a page memory 8.

When an RTC signal exists in a first area 8a of the page memory 8, the size of the picture data is smaller than the size of the paper and the picture data are held in the condition as they are. When the RTC signal exists in a second area 8b of the page memory 8, the size of the picture data is larger than the size of the cut paper a little, the picture data are transferred into a reducing circuit 11 and reduced by matching to the size of the cut paper. Thus, the wasteful use of the cut paper can be prevented.
