たがって、蛇行送りを確実に防止することができる。Note that since the support surface 68 is shifted outward by the dimension a from the reference surface 66 and the guide surface 67, when the postcard 24 is pressed by the guide piece 69, the front of the postcard 24 in the direction of travel is shifted as shown in FIG. It comes into contact with the reference surface 66 and the support surface 68 in a state where it leans inward and the rear side leans outward. On the other hand, since the paper feeding roller 29 rotates with an axis perpendicular to the reference surface 66, the postcard 24 is brought closer to the width as the paper feeding operation progresses and comes into contact with the reference surface 66 and the guide surface 67. It will be fed parallel to the surface 66 and the guide surface 67. Therefore, meandering feed can be reliably prevented.

有する。Effects of the Invention Since the present invention is configured as described above, the ticket in the first cassette case is pulled out by the paper feed roller, conveyed from the ticket conveyance path to the printing section, and printed. When printing on a paper, attach a second cassette case to the front of the housing, press the cards stored in the second cassette case against the paper feed roller using a pressing member, and separate the cards one by one using a gate. The cards can be fed out continuously, and the pressing body is urged by a plate spring to press the cards, but by engaging the locking piece of this plate spring with the second cassette case. This has the advantage that a clamp mechanism for locking the cover in a closed state can be omitted.

項記載の給紙装置。[Claims] 1. A first cassette case located at the bottom of the housing of the printing machine and accommodating a large number of tickets in a stacked state, and a portion near the front edge of the first cassette case. A paper feed roller located at an upper portion, a printing section, and a ticket conveyance path that extends from the front edge of the first cassette case toward the front upper part, passes through a curved surface, and reaches the printing section at the rear are provided. A second cassette case with an opening at the top and having a mounting surface that supports sturdy cards in a stacked state facing an extension surface extending forward from the latter half of the conveyance path after the curved surface is attached to the printing machine. The second cassette case is detachably attached to the front surface of the cassette, and includes a paper feed roller that contacts the cards on the lowest layer, and a paper feed roller that is detachably attached to the second cassette case. A pressing body is provided with gates facing each other with a gap, a cover for opening and closing the top opening of the second cassette case is vertically movably connected to the second cassette case, and a pressing part for pressing the cards is formed at one end. The other end is rotatably connected to the cover, and a plate spring is provided on the rotatable free end side of the cover to bias the pressing body toward the placement surface of the second cassette case. A paper feeding device characterized in that a locking piece that elastically engages with the second cassette case is integrally formed on the plate spring. 2. The paper feeding device according to claim 1, wherein the pressing member is provided with a stopper that comes into contact with the inner surface of the cover to determine the rotation angle of the pressing member. 3. Claim 1, characterized in that the pressing part of the pressing body is located at a position where it does not come into contact with the outer peripheral surface of the paper feed roller.
