Abstract

PURPOSE:To simplify and enhance efficiency of work, by a method wherein a sensor for detecting an end of a paper is provided at a paper guide on one side, and determination of a paper width is automatized by moving the paper guide in accordance with the presence or absence of the end of the paper. CONSTITUTION:A motor 4 for moving a guide is rotated while being controlled by a controlling circuit, and the paper guide 2 on the other side is moved by friction with a guide-fixing shaft 5. The shaft 5 fixes the paper guide 1 on one side, and functions as a rail when the paper guide 2 on the other side is moved. A paper-feeding roller 6 is rotated to feed the paper 7. When the paper 7 is detected by the sensor 3 for detecting the end of the paper 7, the controlling circuit 31 rotate the motor 4 in the direction for enlarging the gap (b) between paper-pressing surfaces of the paper guides 1, 2. On the other hand, when the paper 7 is not detected by the sensor 3, the motor 4 is rotated in the direction for reducing the gap (b) between the paper-pressing surfaces.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an improvement in a ticket inserter attached to a printer.

[Technical background of the invention and its problems]

Conventionally, an operator manually determined the paper width of a cut inserter attached to a printer. For this reason, mismatch between the paper width and the cut inserter may occur, causing paper jams, skews, etc. Furthermore, when using many types of paper, proper width determination is required each time, which creates problems such as cumbersome work and forcing the operator to perform extra work.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to easily and reliably determine the paper width of a cut inserter, and to prevent paper jams, paper skews, etc.

[Summary of the invention]

The present invention includes a pair of paper guides, a motor for moving the paper guides, a sensor for detecting the position of the paper edge provided on at least one of the paper guides for detecting the position of the paper edge, and a motor for moving the paper guide. Based on the output signal, if paper is detected by the sensor, the gap between the paper guides is increased,
A sheet inserter comprising a control circuit that controls the rotation of the motor so as to narrow the interval between the paper guides when no paper is detected, and stops the motor when the output value of the sensor is within a certain range. be.

[Embodiments of the invention]

Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a perspective view of a cut inserter employing the present invention. FIG. 2 is a partially cutaway front view showing the main parts when the paper shown in FIG. 1 is inserted. FIG. 6 is a block diagram of the present invention. Note that the same numbers indicate the same items here. Reference numeral 1 designates one paper guide, which is fixed to a guide fixing shaft to be described later. Reference numeral 2 designates the other paper guide, which is movable in the X-axis direction by a guide moving motor, which will be described later, using a guide fixing shaft, which will be described later, as a rail. Reference numeral 6 denotes a paper edge detection sensor, which is fixed at a distance a from the paper pressing surface of the other paper guide 20, which accommodates the paper.

Further, in this embodiment, it is a photo sensor motor and is fixed to the other paper guide 2, and its rotation axis is in contact with the guide fixing shaft. The guide moving motor 4 rotates under the control of a control circuit, which will be described later, and moves the other paper guide 2 by friction with a guide fixing shaft, which will be described later. A guide fixing shaft 5 fixes one paper guide 1 and serves as a rail when the other paper guide 2 moves. A paper feed roller 6 rotates to feed the paper 7. Reference numeral 8 denotes a driving shaft 1 that drives the paper feed roller. 9 is a back paper guide plate, and 10 is a front paper guide plate, which prevents the paper 7 from falling over. A motor 11 drives the drive shaft 8 by a power transmission mechanism (not shown). 12 is a shaft.

In FIG. 6, reference numeral 61 denotes a control circuit, which controls the rotation of the guide movement motor 40 based on the output signal of the paper end detection sensor 3. Further, arrows between each block indicate the flow of signals. The operation of this embodiment will be explained below with reference to FIGS. 1 to 4.

First, the operator moves the other paper guide 2 so that the distance between the paper holding surfaces of the drawing paper guide 1.2 is approximately equal to the paper 70.
Adjust to width. Next, when a switch (not shown) is turned on, the paper edge detection sensor 6 detects the presence or absence of the paper 7.

As shown in FIG. 4, the paper edge detection sensor 3 outputs a voltage V when the presence of paper is detected, and a voltage 2 when no paper is present (ζ).Control circuit 61 is the distance between the paper pressing surfaces of both paper guides 1 and 2 when the output voltage of the paper edge detection sensor B is 2 as shown in FIG. 4, that is, when paper 7 is detected. The guide movement motor 4 is rotated in the spreading direction. - When the output of the blade paper edge detection sensor B is V2, that is, when the paper 7 is not detected, the control circuit 31 moves both paper guides 1 and 20 to the paper pressing surface. The guide moving motor 4 is rotated in the direction of narrowing the interval between.

In this way, the other paper guide 2 moves using the guide fixed shaft 5 as a rail by the rotation of the guide movement motor 4 controlled by the control circuit 61, and the paper edge detection sensor 6 reaches the paper 7 top, and its output voltage But ■. When this happens, the control circuit 61 detects that the other paper guide 2 is in the proper position and stops the guide moving motor 4. In this way, the other paper guide 2 is in a state where there is a preset appropriate distance a between the edge of the paper 7 and the paper pressing surface.
In other words, the paper guide 1.2 stops when the distance between the two paper guides 1.2 reaches the appropriate value b0.

In this embodiment, an optical sensor is used as the paper edge detection sensor 6, but the present invention is not limited to this, and other sensors may be used. In this case, the sensor needs to detect at least three states: when paper is present, when there is no paper, and when the edge of the paper is present on the sensor. For this reason, the sensor requires analog output or digital output of three or more values. Further, in this embodiment, the output of the paper edge detection sensor B is V. In this case, the guide moving motor 4 was stopped assuming that the other paper guide 2 was at the proper position, but it is also possible to give a range to the output of the sensor at the proper position, depending on the purpose of use etc. Just choose. Further, in this embodiment, a guide moving motor 4 is provided on the other paper guide 2, and the other guide 2 is moved by the frictional force between its shaft and the guide fixing shaft 5.

However, the present invention is not limited to this, and other methods may be used, such as fixing the motor to the main body of the sheet inserter and moving the other paper guide 2 using a wire rope or the like, or using the motor 11. There is no problem.

Further, in this embodiment, the paper edge detection sensor 6 is provided on the other paper guide 2, and only this other paper guide 2 is movable.However, paper edge detection sensors 6 are provided on both paper guides, respectively. It is also possible to make the paper guide movable, and this may be selected depending on the purpose of use.

〔Effect of the invention〕

The sheet inserter of the present invention can prevent paper jams, paper skews, etc. that occur due to mismatch between the paper width and the sheet inserter, which conventionally occurred when an operator manually determined the sheet width.

Furthermore, since the paper width determination of the cut inserter is automated, the burden on the operator is greatly reduced when many types of paper are used, which is extremely effective in simplifying and increasing the efficiency of work.
