As a conventional paper feeding device for a printer, there is one shown in FIG. 4, for example. In the figure, reference numeral 1 denotes a pair of support brackets, on which a platen 2, a drive shaft 3, and a guide shaft 4 are supported. The drive shaft 3 is connected at one end to a drive gear 7 of a drive source via a pulley 5 and a belt 6, and as the drive shaft 3 rotates, the drive shaft 3 and the guide shaft 4 are connected.
A tractor 8 attached to the vehicle is operated. The tractor 8 rotates the tractor belt 9 as the drive shaft 3 rotates, and engages the plurality of protrusions 10 protruding from the tractor belt 9 with the feed holes 12 of a predetermined pitch of the continuous paper 11 for printing. The continuous paper 11 is fed in the direction of arrow A in the figure. However, if the tension applied to the continuous paper 11 is too small, paper feeding accuracy will deteriorate, and conversely, if the tension is too large, it may cause a jam. Continuous paper 1
I was trying to adjust the tension in step 1.

定の経路長としかすることができなかつた。 However, in the paper feeding device of such a conventional printer, a tensioner using a spring is used to adjust the tension of the continuous paper 11, so it is only possible to apply a constant tension to the continuous paper 11, and therefore It was not possible to deal with the expansion and contraction of paper due to changes in paper type, temperature, humidity, etc. That is, the continuous paper 1 is moved between the platen 2 and the tractor 8 in accordance with changes in paper expansion and contraction.
It is not possible to arbitrarily change the length of the path 1, and the path length can only be kept constant.

The paper feeding device of the printer of the present invention passes paper through one of the upper and lower sides of a tractor placed between a pair of support brackets, and then passes the paper through the other one of the upper and lower sides of the tractor via a platen that is spaced apart from the tractor in the paper feeding direction. In a printer that feeds paper by driving a tractor, a long hole is formed through both brackets along the paper feeding direction, and the tractor is rotatably held in conjunction with a drive motor, and both ends are connected to the long hole. The above-mentioned problems of the conventional art can be solved by adopting a configuration that includes a drive shaft that passes through the drive shaft, a pair of square sesame that penetrates through both ends of the drive shaft, and a pair of locking bodies that support the square sesame so that they can be moved and locked in the paper feeding direction. has been resolved.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Note that, in the following, parts common to those in the prior art will be denoted by common reference numerals, and repeated explanations will be omitted. The paper feeding device of this printer has a slide mechanism 20 for adjusting the tension of the continuous paper 11, which allows the tractor 8 to move relative to the support bracket 1.
Specifically, this slide mechanism 20 moves the tractor 8 by enabling the drive shaft 3 to move forward and backward in the feeding direction of the continuous paper 11 (direction of arrow A). The shaft insertion hole 21 is formed as a long hole extending in the direction of the arrow A, and the drive shaft 3 is movable within the range of this long hole. The guide shaft insertion hole 22 of the tractor 8 is formed into a long hole similar to the drive shaft insertion hole 21,
It is designed to allow movement of the tractor 8. Furthermore, both ends of the drive shaft 3 are
It is supported by a bearing 23, which is slidably held by a bearing holder 24 fixed to the support bracket 1. In addition, the bearing holder 24 on the side connected to the drive source
has an insertion hole 25 formed into a long hole similar to the drive shaft insertion hole 21 of the support bracket 1, and allows the drive shaft 3 to move. Further, the belt 6 connected to the drive shaft 3 is provided with an idler 26 for adjusting the tension of the belt 6 when the drive shaft 3 is moved. Furthermore, the bearing holder 24 is provided with a bearing fixing screw 27 that comes into contact with the bearing 23 and tightens and fixes it, so that the bearing 23 can be fixed at a predetermined moving position. Therefore, when adjusting the tension of the continuous paper 11 in response to expansion and contraction of the paper due to changes in paper type, temperature, and humidity, first loosen the bearing fixing screw 27, and then move the tractor 8 with the bearing 23 in a slidable state. Then, by moving the drive shaft 3 and placing the tractor 8 in the optimum position, in this state, the bearing fixing screw 27 is tightened to fix the bearing 23, so that the drive shaft 3 and the tractor 8 are also fixed in that position. As a result, the path length of the continuous paper 11 driven by the tractor 8 changes, and the optimum tension can be obtained regardless of the paper type, temperature, and expansion and contraction of the paper due to changes in humidity.

As explained above, since the paper feed device of the printer of the present invention has the above-described configuration, it is possible to move the tractor and change its position by the slide mechanism, and as a result, the paper feed device of the printer of the present invention can move the tractor and change its position. The paper path length can be changed arbitrarily to easily accommodate paper expansion and contraction due to changes in paper type, temperature, and humidity, and optimal tension can be applied to continuous paper to prevent poor paper feeding accuracy due to insufficient tension. This has the effect of reliably preventing the occurrence of jams due to excessive tension.

る。 Further, since the above-mentioned simple structure is easy to assemble and adjust, remarkable effects on workability can be obtained. Further, even if the tractor is adjusted, the state of engagement between the protrusion (pin) of the tractor and the hole in the paper does not change, and jams do not occur, allowing stable paper feeding at all times and improving quality.
