Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a medium positioning method for stopping a continuous sheet of paper such as a receipt, ticket, ticket, etc. at a desired position to perform printing, cutting, etc.

[Conventional technology]

For example, a printer for recording transactions such as an automatic teller machine uses two sheets of copy paper, one of which is given to the customer as a receipt, and the other is rolled up as a journal for recording. Therefore, it is necessary to cut the receipt side into individual pages and then position them in the line feed direction.

Conventionally, as a method for this positioning other than manual methods, there are the following automatic methods.

The position of the paper is determined by reading marks attached to the medium, such as printed marks or the edges of the paper, using a sensor, and the required position is determined by adjusting the sensor position.

[Problem that the invention seeks to solve]

Such an automatic adjustment method requires delicate position adjustment of the sensor, and this adjustment work is very difficult and takes a long time because it is not easy.

[Means to solve the problem]

The present invention provides a positioning sensor for detecting a line-feeding medium, a means for determining a correction value for a medium line-feed, a means for setting the obtained correction value, and a means for controlling line-feeding of the correction value. It is equipped with the following.

[Effect]

With each of the above means, the present invention allows a medium set at a predetermined position to feed a line while calculating the number of line feeds, calculates the number of line feeds until a positioning sensor detects the medium, and calculates the number of line feeds until a positioning sensor detects the medium and the number of line feeds until a predetermined correct position is reached. Find the difference from the number of line feeds, set the difference as a correction value, then align the leading edge of the medium with the predetermined position, feed the line until the positioning sensor detects the medium, and then move the medium by the correction value. Position the media at the correct position by adding or subtracting line breaks.

〔Example〕

An embodiment of the present invention will be described below using an automatic transaction device.

Figure 2 is a block diagram for positioning the medium, Figure 3 is a flowchart for determining switch settings,
FIG. 4 is a flowchart for positioning the medium, and FIG. 5 is a side view of the automatic transaction device according to the present invention.

In FIG. 5, reference numeral 1 denotes a medium storage section, and 2 a sprocket, which are connected to a feed motor (not shown) which rotates in forward and reverse directions. 3 is paper cutter, 4
1 is a cutting knife, 5 is paper as a medium, 6 is a positioning sensor, 7 is a printer, 8 is a winding unit, 9, 1
0 is a drive roller.

In Figures 1 and 2, 11 is a CPU;
Reference numeral 12 is a memory, and 13 is a display section, which is composed of LEDs, liquid crystals, and the like. Reference numeral 14 represents a control circuit for controlling the feeding of the medium, and reference numeral 15 represents a line feed mechanism section, which is comprised of the feed motor, power transmission means, and sprocket.

Reference numeral 16 denotes a detection circuit, which includes the positioning sensor 6 used to stop the medium 5 at a desired position on the medium running path and a circuit for generating an output signal thereof. 17 is a switch, and 18 is a switch reading circuit.

Next, the operation of the above configuration will be explained.

The medium 5 stored in the medium storage section 1 is fed by the sprocket 2, the recording journal is wound on the winding section 8, and the receipt to be given to the customer is sent to the cutting knife 4.
The pages are cut one by one by the drive rollers 9 and 10.
sent by.

The receipt positioning operation is performed as follows. The receipt is sent to the drive roller 9 by the sprocket 2, and further sent to the positioning sensor 6, and after being detected by the positioning sensor 6, the receipt feed is further increased/decreased according to a switch setting value described later to determine the position. .

The above operation will be explained in more detail with reference to FIGS. 1 to 4.

First, a method for determining the above-mentioned switch setting values will be explained with reference to FIGS. 1 and 3.

Operate the switch 17 to run the medium 5 and find the positioning sensor 6 while calculating the number of line breaks. When the positioning sensor 6 is found, the number of line feeds up to that point is compared with the number of line feeds up to the correct installation position predetermined in the memory 12, an increase or decrease in the number of line feeds is determined, and this is displayed as the switch setting value. Displayed in section 13. This displayed number is set in the switch 17 and used as the switch setting value.

Next, positioning of the medium 5 will be explained with reference to FIGS. 2 and 4. When the switch 17 is operated, the medium 5 travels and feeds the line until it finds the positioning sensor 6. When the positioning sensor 6 is found, the positioning operation of the medium 5 is completed by adding or subtracting the number of line feeds of the switch setting value obtained above to the number of line feeds so far.

Note that the above switch setting values can also be set programmatically and do not necessarily require a switch on the machine. The positional deviation of the positioning sensor may be corrected by reading out the correction value.

〔Effect of the invention〕

According to the present invention described above, since the positioning operation of the medium is corrected by the switch setting value, there is no need to adjust the position of the positioning sensor provided in the traveling path of the medium, and the manufacturing of the device is facilitated. At the same time, operability will also improve.
