Description of the Related Art In recent years, there has been an increasing demand for printers with good print quality that are less susceptible to environmental changes and operator operations. Along with this trend, a paper feeding mechanism has been proposed to cope with expansion and contraction of the printing paper in the width direction caused by changes in humidity and the like. As a conventional technique in this field, a sheet feeding mechanism disclosed in Japanese Patent Laid-Open No. 3-216447 is known. As shown in FIG. 5, the content disclosed herein is such that the tractor 2 is supported by the tractor 2 so as to be movable within a predetermined range in the lateral direction (the left-right direction which is the width direction of continuous paper). And the pin belt 3 provided between the pin belt 3 and the tractor 2.
The spring member 6 for urging the sheet to the right (the direction in which the width of the continuous sheet is widened) and the sheet pressing plate 12 for preventing the continuous sheet (not shown) from coming off the tractor 2 were provided.

た。However, in the above structure, the pin belt 3 is moved so that the pin 4 of the pin belt 3 formed in the paper pressing plate 12 has a nib for the pin 4 and a paper feed hole (not shown). Engagement confirmation hole (not shown)
Therefore, there is a drawback that the pressing force of the paper pressing plate 12 is reduced and the paper is displaced from the pin 4.

が発生する危険があった。Further, by the spring force of the spring member 6 for urging the pin belt 3 to the right (the direction in which the width of the continuous paper is widened),
There is a risk that the sliding load between the pin belt 3 and the holder (not shown) becomes large, and the pin belt, which is important for the paper feeding mechanism, is worn.

い欠点があった。Since the spring member 6 urges the pulley (not shown) around which the pin belt 3 is stretched, the side surface of the pulley (not shown) and the holder (not shown).
There is a drawback that the load on the surface becomes large and stable paper feeding cannot be performed.
【0008】また、プーリ部とホルダ部での紙幅方向の

点があった。Further, since the abutting force in the paper width direction at the pulley portion is different from that at the holder portion, there is a drawback that continuous paper is fed obliquely.

るという欠点があった。Further, in contrast to the above, one side surface of the tractor that slides by the guide of the guide shaft is locked to a frame which is a member by interposing a spring material which is an elastic member, and A structure in which a frame is provided with a lock mechanism is proposed in Japanese Patent Laid-Open No. 1-271344. However, in the above-described configuration, when setting the paper, the operator needs to position the tractor 2 so that the pin belt 3 comes to the center of the movable range of the tractor. For this reason,
At the same time that there is variation in the paper set by the operator, at the same time it is necessary to carefully check the pin belt 3 section to confirm the set position, there is the drawback that the variable amount in the paper width direction with respect to the paper width set is not stable. In addition, there is a drawback that it is erroneously set so as to hit the inner side of the tractor at worst.

対応がなされないという欠点があった。Further, by widening the space between the holders so that the pin of the rotating body is located outside the center of the feeding hole of the continuous paper, tension in the width direction is applied to the continuous paper, and when the lock lever is operated, the braking member is operated. Japanese Patent Application Laid-Open No. 1-267247 proposes a structure in which is engaged with and fixed to a guide shaft. However, the above-described configuration has a drawback that the structure in only one direction (the direction in which the paper is stretched) cannot deal with the case where the continuous paper is shrunk.

It is an object of the present invention to provide a paper feeding mechanism with improved structural defects.

動可能な溝11が設けられている。A drive shaft 7 and a guide shaft 8 are arranged in parallel with a platen (not shown) on a side frame (not shown) of the printer (not shown), and the drive shaft 7 is rotatably supported. Has been done. A pair of tractors 1 and 2 are slidably attached to these shafts. The tractor 2 is provided with a pin belt 3 having a plurality of pins 4 formed at equal intervals, and the pin belt 3 has a structure that is movable as the drive shaft 7 rotates. A paper pressing plate 12 having a pin hole (not shown) of a pin 4 is attached to the upper portion of the tractor 2 so as to be openable and closable around a support shaft (not shown) as a fulcrum. Then, the pressing force of the paper pressing plate 12 is determined by the spring force of the spring member 14 suspended on the tractor 2 and the paper pressing plate 12. A spring member 6 interposed between a holder 2b that rotatably supports a pulley 5 around which a pin belt 3 is stretched and a frame member 19 is sandwiched so as to bias the tractor 2 to the left. The frame member 1 is provided on the side surface of the tractor 2.
A lock mechanism is provided for fixing 9 to the guide shaft 8 and for moving the tractor 2. The cylindrical portion 18 formed on the side surface of the tractor 2 and the lock lever 9 adjacent to the outer side of the tractor 2 slide relative to each other in the axial direction of the guide shaft 8 by a connecting shaft (not shown) by a distance indicated by a dimension line B. The sleeve 20 is fitted between the lock lever 9 and the cylindrical portion 18. Further, the groove 11 which is movable in the distance is provided on the outer peripheral surface of the cylindrical portion 18 formed on the side surface of the tractor 2.

The paper feed plate 17 is closed by engaging the feed hole 17a formed on the right side. Lock lever 10
Thus, the guide shaft 8 and the tractor 1 are engaged and locked. Then, the pin 4 of the pin belt 3 provided on the other tractor 2 is engaged with the feeding hole 17a formed on the left side of the continuous paper 17 to close the paper pressing plate 12. Next, FIG.
As shown in (b), the guide shaft 8 and the tractor 2 are engaged and locked by the lock mechanism provided on the left tractor 2. At this time, since the tractor 2 slides in the direction in which the continuous paper 17 is stretched (the direction of arrow C) and the spring member 6 is biased, a constant tension is automatically applied to the continuous paper 17.

As a result, variations in sheet setting by the operator are eliminated, and stable sheet setting is always possible, and operability can be improved. Further, since a tractor capable of following a change in the width of the paper due to a change in humidity is formed, it is possible to prevent a jam of the paper due to a hole passing through the paper.
