A printer that prints desired characters, numbers, or symbols on a printing sheet is generally configured to be able to use both single-cut sheets and continuous sheets. In this case, the single-cut sheet feeding device is composed of a paper set table on which the single-cut sheets are placed and a paper feed mechanism mainly composed of rollers for feeding the single-cut sheets (example Japanese Laid-Open Publication No. 57-84884, Japanese Laid-Open Publication No. 60-8
No. 3753 gazette) is common. The edges of both sides of the cut sheet set on the sheet setting table are regulated by the reference side plate and the sheet guide to prevent the positional deviation in the width direction.
The paper guide is arranged so that it can be moved and adjusted in the width direction of the paper, that is, in the direction in which it approaches and separates from the reference side plate, so that it can accommodate various sizes of paper. A warp prevention member is provided above the front end of the paper set base on the side of the reference side plate, and a warp prevention member is provided to prevent the side end of the cut sheet from rising and rising. A pick roller for feeding a single-cut sheet is arranged in the center of and. The pick roller is configured so that it is always set and held in the widthwise center of the paper regardless of the size of the paper by moving in the same direction at a speed half that of the guide in conjunction with the paper guide. There is.
