Description of the Related Art In recent years, some image printers have an automatic paper feed mechanism for continuously and automatically supplying a special recording paper to a recording section in the apparatus. Among simple paper feeding methods, there are generally a nail method and a slit type paper feeding method as disclosed in Japanese Patent Laid-Open No. 54-8595. However, due to curling, electrostatic contact, etc., the paper feeding reliability is high. I can't say. Therefore, conventionally, in order to improve reliability, a friction retard type sheet feeding mechanism has been adopted.

な搬送を得られる。FIG. 2 (a) is a sectional view of a main part in the embodiment of the present invention, and FIG. 2 (b) is a side view of the same. The limiting member 9 is rotatably supported by the shaft 8a of the paper feed roller 8 and is rotatable within a range limited by a stopper. The upper surface 9b of the tapered surface guides the recording paper 12 and the lower surface of the tapered surface. A plurality of recording papers 12 can be formed by reducing the distance from 9a.
The recording paper 12 below is judged by sequentially restricting. The end portion of the limiting member 9 is set to be slightly wider than one sheet of the recording paper 12 (for example, the paper thickness is 0.2 mm).
If it is 0.25 mm), leave 1 sheet of recording paper 1
2 will pass. Here, by setting the narrowest slit part immediately after the paper feed roller 8, the reliability can be improved without being affected by the curl of the recording paper 12. Further, as shown in FIG. 2B, the limiting member 9
Paper feed roller 8 through which the recording paper 12 of FIG.
Since c is most strongly influenced by the curl of the recording paper 12, a smooth conveyance can be obtained by setting a sufficiently wide gap (for example, 10 mm) that matches the curl characteristic of the recording paper 12 used.
