Abstract

PURPOSE:To facilitate the positioning of a paper guide in the widthwise direction to make it possible to stably feed paper, by coupling and associating the paper guide with a tractor for continuously feeding paper. CONSTITUTION:When a tracter 1 is moved along a support shaft 6 in accordance with the width of a continuous paper sheet 3 to be used, a paper guide 8 coupled to the tractor 1 slides on the guide surface of a guide bracket 9 in association with the movement of the tractor 1 to guide the widthwise position of the continuous paper sheet 3 as indicated by the arrow B with respect to the feeding direction of the continuous paper sheet 3 as indicated by the arrow A. Accordingly, the continuous paper sheet 3 is prevented from being obliquely directed, and therefore is led precisely. Further, the continuous paper sheet 3 led by the paper guide 8 is turned in its feed direction while pins 4 on the tractor 1 are successively fitted into sprocket holes 2. Accordingly, the paper sheet is fed into a printer section for printing.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a paper feed device for conveying continuous paper to an output device of an information processing device, and in particular to a paper feed device with an improved mechanism for preventing skewing of continuous paper having sprocket holes. It is related to.

[Prior Art] Conventionally, as shown in FIG. 3, this type of paper feeding device has a tractor 13 that feeds paper 11 by inserting a pin 12 into a sprocket hole formed in continuous paper 11, and a tractor 13 that feeds paper 11 continuously. Paper guides 14 are provided independently to prevent the paper 11 from being tilted during feeding.

[Problems to be solved] In the conventional paper feeding device described above, the tractor 13 and the paper guide 14 are separated and each is independent, so when setting the continuous paper 11, it is necessary to Both the tractor 13 and the paper guide 14 must be operated by the machine, which is a complicated operation.If alignment is insufficient, the continuous paper 11 may become skewed, and the continuous paper 11 may come off the tractor 13, resulting in unstable operation. The drawback is that it cannot be done.

[Means for Solving the Problems] The present invention solves the above-mentioned conventional problems, and provides a paper feeding device for transporting continuous paper guided by a paper guide by a tractor, which includes a side plate, a support shaft attached to the side plate, and a support shaft attached to the side plate. a tractor that is positioned by sliding along an inscription support shaft according to the paper width of the continuous paper, and transports the continuous paper by sequentially inserting its pins into sprocket holes provided in the continuous paper; The paper guide is connected to the tractor, moves in conjunction with the tractor, and is positioned in accordance with the paper width of the continuous paper.

[Examples] Examples of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the configuration of a paper feeding device in a printer device according to an embodiment of the present invention.

In the figure, reference numeral 1 denotes a tractor that sequentially fits continuous paper 3 having sprocket holes 2 at equal intervals in the longitudinal direction onto pins 4 and sends it out. The tractor 1 is slidably supported in the support portion 1a by a support shaft 6 attached to a side plate 5, and is rotatably driven by a drive motor (not shown) via a drive shaft 7.

A paper guide 8 is coupled to the support portion 1a of the tractor 1, and is configured to move in conjunction with the tractor 1. This paper guide 8 is movable along a guide bracket 9 attached to the side plate 5 in parallel with the support shaft 6.

Next, the operation of the paper feeding device in the printer device having the above configuration will be explained. That is, when the tractor 1 is moved along the support shaft 6 according to the width of the continuous paper 3 used, the paper guide 8 connected thereto slides on the guide surface of the guide bracket 9 in conjunction with the tractor 1. The feeding direction of the continuous paper 3 is indicated by arrow A in FIG. ),
The position of the continuous paper 3 in the width direction (indicated by arrow B in FIG. 1) is guided.

Therefore, the continuous paper 3 is prevented from being tilted to the feeding direction by the paper guide 8, and is accurately guided in the feeding direction. As shown in FIG. 2, the continuous paper 3 guided by the paper guide 8 has its feeding direction changed by the feed roller 10, and further, the pins 4 of the tractor 1 are sequentially fitted into the sprocket holes 2, and the continuous paper 3 is sent to a printer section (not shown). Printing is performed.

[Effects of the Invention] As explained above, the paper feeding device of the present invention is configured such that a paper guide for preventing the continuous paper from being tilted with respect to the paper feeding direction is connected to the tractor that feeds the continuous paper, and the paper guide is operated in conjunction with the tractor. Therefore, it is possible to easily position the paper guide in the width direction, improve operability, and stably feed the paper.
