８，４１５に記載されている。Conventionally, this type of paper feeding device feeds the cut paper on the paper feeding device to the platen when the platen is reversed, and aligns the leading edge of the cut paper by pressing the leading edge of the cut paper against the paper suction port of the platen. The cut paper was conveyed to a predetermined position by normal rotation of the platen. A conventional paper feeding device of this type is the Japanese Patent Publication No. 5G-6633 or USP 4,24.

とを特徴とする。The present invention provides a paper feeding device used in conjunction with a printing device having a platen, which includes a paper separation roller that separates cut sheets one by one and feeds the paper to the platen, and a paper separation roller that separates cut sheets sheet by sheet and feeds the sheets to the platen, and a driving force of the platen that separates the sheets. The intermittent drive device includes an intermittent drive device that can transmit information to the roller or separate and do not transmit the information, and a unidirectional rotation drive device that allows the paper separation roller to rotate only in the forward rotation direction, and the intermittent drive device With the drive force being transmitted, the platen rotates forward, causing the paper separation roller to feed the cut paper to the platen, and the leading edge of the cut paper to or from the lower entrance between the platen and the indexing/feeding roller. After reaching the innermost part of the paper, without transmitting the driving force to the intermittent drive device, the leading edge of the cut paper, which has been sucked once by reversing the platen, is returned to the lower entrance, and after the cut paper is started, the platen is moved again. The cut paper is fed to a predetermined position by normal rotation of the cut paper.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
第１図は本発明の一実施例の正面図であり、第２図〜第
４図は本実施例の動作を説明するための側面図である。FIG. 1 is a front view of one embodiment of the present invention, and FIGS. 2 to 4 are side views for explaining the operation of this embodiment.
プラテン１の回転は歯車列からなる駆動伝達装置２によ

転するようにされている。The rotation of the platen 1 is transmitted by a drive transmission device 2 consisting of a gear train to an intermittent drive device 3 consisting of an electromagnetic clutch or the like. The intermittent drive device 3 further transmits the rotation from the drive transmission device 2 to the paper separation roller 5 or interrupts this transmission based on commands from a control section (as shown). Further, the paper separation roller 5 is provided with a negative direction drive device 4 so as to rotate only in the forward rotation direction.

の伝達を中止させる。First, the platen 1 is rotated forward with the intermittent drive device 3 transmitting the rotation from the drive transmission device 2 to the paper separation roller 5, and as shown in FIG.
When the leading edge 8 of the cut paper 6 is fed to the lower entrance of the platen 1 and the beginning/feeding roller ruff, or deeper than that, the intermittent drive device 3 is made to stop transmitting the rotational force to the paper separation roller 5.
次に、第３図に示すように、プラテン１を逆転させて、
カット紙６の先端を低級入口まで戻し、用紙先端を揃え

転させて、カット紙６を所定の位置まで送る。Next, as shown in FIG. 3, the platen 1 is reversed and
Return the leading edge of the cut paper 6 to the lower entrance, align the leading edges of the paper, and then rotate the platen 1 in the normal direction again while the intermittent drive device 3 stops transmitting rotation to the paper separation roller 5, as shown in FIG. , feed the cut paper 6 to a predetermined position.
以上説明したように本発明は、用紙先端を揃えてから用

行を無くす効果がある。As described above, the present invention has the effect of increasing the positional accuracy of cueing and eliminating skewed feeding of the paper because the paper is fed after aligning the leading edges of the paper.

する給紙装置。A paper feeding device used in conjunction with a printing device having a platen includes a paper separation roller that separates cut sheets one by one and feeds them to the platen, and a paper separation roller that transmits the driving force of the platen to the paper separation roller. an intermittent drive device that can be separated and not transmitted; and a unidirectional rotation drive device that allows the paper separation roller to rotate only in the forward rotation direction, and transmits driving force to the intermittent drive device. In this state, the paper separation roller feeds the cut paper to the platen by normal rotation of the platen, and the leading edge of the cut paper reaches the paper suction port between the platen and the beginning/feeding roller, or is deeper than that. After reaching the point, the leading edge of the cut paper that has been sucked in by reversing the platen is returned to the paper suction port without transmitting the driving force to the intermittent drive device, the leading edge of the cut paper is returned to the paper suction port, and the platen is rotated again in the correct direction. A paper feeding device characterized in that the cut paper is fed to a predetermined position by rotating the cut paper.
