Title: Paper feeder for electrophotographic copier
Inventor: KAWAKUBO TOSHIO
IPC: B65H1/00
Filed: 1978-04-10
Abstract: PURPOSE: To insert various sizes of paper into a relatively small device so that a single feeder may be applied to a common use, while simplifying the mechanism, by providing a fixing device, which is operative to selectively fix a plurality of copy paper receiving container, at a paper feeding section.  
     CONSTITUTION: The guide rails 11, which are disposed at the both sides and in the vicinity of a paper feeding section while taking an upright position, are operative to guide a number of paper feed cassettes while the latter are accommodated inbetween, and are formed at their center with a curved passage 12 directed toward the paper feeding section. The cassette 20 is equipped at its both side walls 21 with rollers 24 which are brought into sliding engagement with the guide rails 11 so that the cassette 20 can be moved up and down. A magnet 23 for indicating the size of the copy paper is buried in a suitable position of the front wall 22 of the cassette 20. A magnetic sensor 32 is disposed in the end wall of the paper feeding section, which is in contact with the front wall 22. Thus, the size of the paper used can be detected. As a result, it is possible to improve the paper feeding performance by the common use of the single paper feeding device.

Title: Cutting body feeding device in cutting machine
Inventor: OUMI YUMA
IPC: B26D3/30
Filed: 1990-02-21
Abstract: PURPOSE:To correctly hold a cutting body on a center line, by providing an inside tension member at the inside of a transfer belt and forming a structure of approaching the transfer belt to the center line mutually by giving an energizing force to the tension member. CONSTITUTION:A moving shaft 70 is pulled to the left by the elastic force of a compression spring 82 in a normal state. Accordingly the inside tension rollers 51, 51 connected to the moving shaft 70 via a link member 80 and connection plate 62 is drawn to the direction approaching to a center line X and so a transfer belt 20 is pushed out in the center line X direction. When one part of the inside tension rollers 51 is pushed in the direction apart from the center line X, the moving shaft 70 is drawn to the right side against the compression spring 82. The other part of the inside tension roller 51 is then moved in the direction apart from the center line X as well similar to the above because of its being connected to the same moving shaft 70. The both inside tension rollers 51, 51 are thus held at the symmetrical position to the center line X and a cutting body is correctly held on the center line.
