JPS6036181A - Paper-feeding mechanism for printing part in printer for sheet form paper - Google Patents

Abstract

PURPOSE:To enable to perform continuous automatic printing by a printer for sheet form paper, by a method wherein a printing medium constituting a printing line orthogonal to the feeding direction of a paper is provided between two adjacent sets of rollers. CONSTITUTION:A sheet form paper, particularly a thick paper card, is fed so that information stored in a computer can be printed on the paper while assuming that the paper is continuously supplied. Namely, the sheet form paper 1 is fed toward the printing medium 5 by feeding rollers 2. In this case, stability of position in vertical and transverse directions relative to the feeding direction is secured by a feeding surface 3 and a guide 4, while a required feed quantity is obtained by the rotation of the rollers 2. In this condition, the paper is passed between the printing medium 5 and a platen 6 while being printed, then the leading end of the apper 1 reaches the second feeding rollers 2', thereafter the paper 1 is separated from the first feeding rollers 2, and is fed by the second feeding rollers 2'. The sheet form paper feeding mechanism thus constructed can contrive to automatically feed the paper into the printing part and to automatically discharge the paper from the printing part. In addition, thick paper cards which are difficult to bend can be also fed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing cloth paper feeding mechanism for a sheet-fed paper printer used in a computer terminal printer for printing on sheet-fed paper such as Car F''In1. be.

2. Description of the Related Art Conventionally, printers that print information stored in a computer on paper have generally used continuous paper in the form of a band, and paper feed mechanisms have generally used feed holes. In other words, using a series of paper is the paper feeder (1) that has become the method of continuous paper feeding and feeding direction position control. (Although the print medium is within the size of the paper feed direction of the two sets, there is no paper feed mechanism that is used between the set feed 1" and 1"), and sheet-fed paper is used. It is not suitable for continuous paper feeding and printing.

This invention is applicable to sheet-fed paper, especially cardboard paper 1"J:+'i
A paper feeder 1f that can print out 'If information stored in a computer assuming continuous feeding of paper.
The purpose of Li is to obtain 'i.

This invention will be explained with reference to figures showing embodiments of the invention. A sheet-fed paper (J,) is conveyed by a feed roller (2) toward a printing medium (5). At this time, transfer surface (:()

(The leading edge of the paper (1) is caught, and then it leaves the feed roller (2) of one set 1-1 and is carried out by the feed rollers of two sets 1-1 (powder).

The sheet-fed paper transport mechanism configured as described in 1-1 can automate the feeding of paper to the printing section and the transport of paper from the printing section. Furthermore, since the paper conveyance surface is configured linearly, it is possible to easily convey cardboard cards that are difficult to bend.

As explained above, this invention makes it possible to continuously and automatically print computer-held information on sheet-fed paper, especially cardboard carts such as F-bills, and makes a great contribution to the streamlining of office work.
(This is an invention.
