る。A pin feed unit, which is generally used as a paper feeding mechanism of a printer, is removable from the printer, which is a recording device. FIG. 1 is a perspective view of the printer 2 equipped with a pin feed unit 4. This pin feed unit 4 engages the holes of the continuous paper 6 with holes on the image side with the pins of the pin wheel 8, and 6 is held between the tractor 10 and the tractor lid 12. In the figure, 14 is a gear chamber, and the gear (not shown) in the gear chamber 14 and the gear (not shown) in the printer 2 are engaged, and the gear in the printer 2 is rotationally driven. The driving force is the gear chamber 14
The paper 6 is conveyed through the inner gear, the square shaft 16, and the pinwheel 8, and the pinwheel 8 rotates, thereby feeding the paper 6.

を有した。The inside of the printer 2 is usually equipped with a frictional rotation means (not shown) so that continuous paper 6 with holes on both sides can be used, as well as paper with no holes on both sides. Paper can be transported. However, when using continuous paper 6 with holes on both sides, if the friction rotation means and the pinwheel 8 are both driven to feed the paper, synchronization cannot be achieved, so the friction rotation means is not driven and the pinwheel is fed. It is customary to feed the paper using only the 8. However, at this time, the engagement between the paper 6 and the frictional rotation means is shortened, causing the paper 6 to sag. For this purpose, there has conventionally been a method in which the printer 2 or the like is provided with a paper presser made of wire or the like, and this paper presser is applied to the paper 6 before it is inserted into the printer 2 to take up the slack in the paper 6. However, this method has the disadvantage that the structure of the paper pressing means is complicated, leading to an increase in cost.

りに支障を来たすことがあった。Furthermore, when using cut paper without holes on both sides with the pin feed unit 4 attached, the friction rotation means inside the printer 2 is used to feed the cut paper without using the pin wheel 8. However, the edges of cut paper are often curled, and therefore, the edges of the cut paper may get caught between the tractors 10 and M12, causing problems in subsequent paper feeding.

る。FIG. 3 is an enlarged perspective view of a portion corresponding to section (■) in FIG.
B is the paper feeding side of the printer 2. In the figure, the paper control means 20 is shown in a state where it is overturned to the paper delivery side A, and in this state, the thickness of the protrusion 24 formed on the paper control means 20 is greater than the thickness of the tractor lid 12. FIG. 4 is a sectional view taken along the line MM in FIG. 2.
The paper control means 20 when tipped over to the paper feed side A is shown by a solid line (and broken line), and the paper control means 20 when turned over to the paper feed side B of the printer 2 is shown by a dashed line. It represents. As shown in the figure, a paper control means 20 is provided on the paper sending side.
When the paper control means 20 is overturned, the protruding portion 24 is projected, and when the paper control means 20 is overturned on the paper feeding side B, the upper surface of the paper control means 20 is configured to be approximately horizontal. In addition, 26.
Reference numeral 28 denotes a paper feed port and a paper feed port respectively provided in the printer.

れる。即ち、紙制御手段２０は用紙６の案内となる。Next, the effect will be explained. FIG. 5 is a sectional view of the bin feed unit 4 when using continuous paper 6 with holes on both sides, and at this time the paper control means 20 is turned over to the paper feed side B of the printer 2. When using continuous paper 6 with holes on both sides, the rotary friction means built into printer 2 is not interlocked, and the paper is fed by pinwheel 8 (FIG. 1). For this reason, as mentioned above, slack occurs in the paper, but the paper control means 2
0 is placed on the continuous paper 6 with holes on both sides on the paper feed side, p-pack tension is applied by the weight of the paper control means 2o, and the slack of the continuous paper 6 with holes on both sides is removed. Furthermore, the continuous paper 6 with holes on both sides sent out from the delivery port 28 of the printer 2 is conveyed along the upper surface of the paper control means 20, but since the upper surface of the paper control means 20 is approximately horizontal, it is conveyed smoothly. . That is, the paper control means 20 serves as a guide for the paper 6.

ことができる。FIG. 6 shows a case where a cut paper 30 without holes on both sides is used. In this case, the rotary friction means built in the printer 2 and the cut paper 30 come into contact, and the cut paper 30 is friction fed. The cant paper 30 is fed by this. At this time, if the paper control means 20 is turned over to the paper delivery side A of the printer 2, the protrusion 22 provided on the paper control means 20 will cause the tip of the cut paper 30 to touch the tractor 1o and the tractor lid 12 (first (Figure) can be prevented from being caught between the two.
尚本発明は上記実施例に限定するものではなく、例えば

に、記録装置に一体となったものであっても良い。It should be noted that the present invention is not limited to the above-mentioned embodiments; for example, the tractor may be a belt type instead of a pin feed type, and the main paper feeding mechanism may not be attached to or detached from the recording apparatus, but may be integrated with the recording apparatus. It may be something that
