うにしたことを特徴とする用紙押え機構。A printer that winds up a predetermined amount of cut paper fed from an automatic paper feed mechanism by rotating the platen, then reverses the platen to return the cut paper to a preset position, and then brings the cut paper into close contact with the platen. A paper holding mechanism comprising: a drive gear fixed coaxially with the platen, a gear meshed with the drive gear via an idle gear, a planetary gear interlocked with the gear, and abutting against the platen. A paper presser shaft with a paper presser roller attached thereto, the paper presser shaft supported at one end so as to be parallel to the platen, and a sector gear engageable with the planetary gear formed at the other end; comprises a rotatable arm provided with a pin, a toggle spring acting on the arm so as to hold the arm in a position where the paper press roller contacts the platen or a position where the sector gear meshes with the planetary gear; and a toggle spring provided on the arm. □ with a rotatable operating lever that engages the
By rotating the arm via a pin using an operation lever, the paper presser roller attached to the presser shaft moves away from the platen, and when the platen is reversed, the planetary gear and sector gear engage, rotating the arm. A paper holding mechanism characterized in that the paper holding roller is brought into contact with a platen.
