Abstract

PROBLEM TO BE SOLVED: To stabilize paper traveling and improve paper traveling accuracy, by grabbing paper with a belt to eliminate effect of a gap in a paper traveling route and by restraining insertion of a lateral perforation into the gap. SOLUTION: By grabbing paper 7 virtually with a belt 3, gaps in a traveling route of the paper 7 decreases, and the paper 7 traveling is stabilized. In this time, the belt 3 supports range from a tractor 5 to a platen 2. The belt 3 is pinched at sprocket hole 8 parts which are at the right and left of the paper 7. However, gaps occur at the borders between the tractor 5 and the belt 3, and between the belt 3 and the platen 2. Therefore, by attaching a plate 4 to the gap, the insertion of a lateral perforation 9 is prevented. To prevent the scratching jam of the lateral perforation 9 and others which is caused by insertion of the plate 4 and to feed the paper 7 smoothly, the plate 4 is arch shaped.

れる。[0003] The paper 7 is used as a continuous form.
In many cases, the horizontal perforations 9 are evenly inserted into an arbitrary page length of each continuous form in order to separate the paper 7 into each form and to fold the form at the time of packing, etc., because it is often used as a copy sheet of a form. ing. A feed hole 8 is used to feed the sheet 7 by line feed and page break in the direction of the arrow shown in the figure.

写紙は特に折り目がきつい。In many cases, the paper 7 is folded and packed, and therefore, as shown in FIG. 3, a horizontal perforation 9 is creased in a mountain fold 10 and a valley fold 11 with respect to a printing surface. Even if the fold is stretched flat once, it is easy to break, and the copy paper is particularly sharp.

す。When the paper 7 is transported, the roller applies a load to the paper 7 by a transport route of the paper 7 (particularly, a printer of a winding type of the paper 7), and the load and the paper 7 described above are applied.
The gap 13 in the transport route affects the transport of the sheet 7.

か行っていない。The tractor 5 pushes the paper 7 toward the print head at the paper 7 suction port (hereinafter referred to as a push tractor system) or pulls the paper 7 above the print head 1 (hereinafter referred to as a pull tractor). However, only the pin 6 portion of the tractor 5 is fixed in the sense that the paper 7 travels accurately, and the other portions only secure the paper 7 feed route. Not.

詰まりと言う問題が発生する。Since the sheet 7 has a degree of freedom in the transport direction, when a load is applied to the sheet 7 during traveling, the sheet 7 bends at the portion of the horizontal perforation 9, and the bent horizontal perforation 9 is formed as described above. The fold of the horizontal perforation 9 enters the gap 13 and the paper 7 is insufficiently fed. If the paper 7 feed amount is insufficient, the effect on printing will be such that the line feed amount is insufficient, and if image data such as hard copy is received and a line feed operation is included in the character, a problem of print clogging occurs.

Since the insufficient amount of paper 7 may be sent, overfeeding may occur. If overfeeding of paper 7 occurs, the effect on printing will be caused by overfeeding of line feeds, when image data such as hard copy is received, and line feeds are inserted in characters.
A problem called white line may occur.
