Description

Description: TECHNICAL FIELD The present invention relates to an adjustment method of an emboss reading device capable of automatically mounting and adjusting the emboss reading device in an automatic transaction device equipped with the emboss reading device.

(Prior Art) Conventionally, in an automatic transaction apparatus equipped with an emboss reading device, a mounting adjustment method of the reading device has been performed as follows.

That is, an emboss reading device including a reading sensor is attached to a predetermined position on the card travel path using a jig or the like so as to cover the area of the emboss data on the surface of the card on the card travel path.

Next, the adjustment medium is placed under the reading sensor, an image of the surface of the adjustment medium is illuminated from above with a light source, and the reflected light is converted to a voltage by the CCD sensor according to the amount of reflected light, and the voltage is converted to an oscilloscope. Then, while observing the level, finely adjust the mounting position of the reading device so that the reading area matches.

(Problems to be solved by the invention) However, the above-described conventional technology has the following problems.

That is, the adjustment cannot be performed without a measuring device that measures the voltage level output by the CCD sensor according to the amount of reflected light. Usually, a measuring instrument is not placed at a place where an automatic transaction apparatus equipped with an emboss reading device is installed (a bank or the like). Furthermore,
To make adjustments, you must carry a measuring instrument.

Make fine adjustments while checking the voltage level on the measuring instrument.
It can only be seen when the adjusting medium is stationary under the emboss reading sensor. Therefore, when reading the image on the surface of the card while the card runs under the embossed reading sensor, or when the reading sensor moves above the card, the mounting position is adjusted once the card or the reading sensor is stationary. Then, while moving the card or the reading sensor, read the image of the card, and output the image to an output device such as a printer or CRT,
The quality of the movement of the card or the reading sensor was judged.

The present invention has been made in view of the above points, and in an automatic transaction device equipped with an emboss reading device, a measuring device is required when adjusting the emboss reading device, for example, a place where the automatic transaction device is installed Therefore, when adjusting the emboss reading device, the position where the emboss reading device is mounted is determined by oneself to eliminate the problem that the measuring device becomes indispensable, and the reading area of the reading device is automatically corrected by itself. Only the correction result is notified to the adjuster. It is an object of the present invention to provide a method of adjusting an emboss reading device that does not require a measuring device, only by checking the result by an adjuster.

(Means for Solving the Problems) According to an adjustment method of an emboss reading device of the present invention, an adjustment medium holding mounting position detection emboss data for detecting a mounting position of a reading device is put into a reading device, and Using the reading device to measure the mounting position using the reference position detection emboss data held in the adjustment medium, according to the measured value, to adjust the reading area of the reading device,
The adjustment medium holding the reading state detection emboss data for detecting the reading state of the reading apparatus is inserted into the reading apparatus, and the reading apparatus uses the reading state detection emboss data held on the adjustment medium by the reading apparatus. The reading state of the reading device is measured by using the reading device, and the reading state of the reading device is adjusted according to the measured value.

(Operation) In the adjusting method of the emboss reading device of the present invention, the reading device detects a reference position indicated by the mounting position detecting emboss data held on the adjustment medium, and determines the reference position and the reference value of the reading device. Compare with position. Then, the reading position of the reading device is corrected according to the correction value obtained from the comparison result. The reading device detects a reference reading state based on the reading state detection emboss data held on the adjustment medium, and outputs the detection result. Then, the reading of the reading device is corrected according to the output value.
Therefore, a measuring device is not required, and the adjustment work is easy.

When the area of the emboss data on the surface of the adjustment medium 2 and the center of the area to be read by the reading sensor 3 are aligned,
That is, when the attachment is performed without error, the value of the data at the center position among the N data for one line becomes the minimum value. That is, the value of the N / 2-th data becomes the minimum value.

Here, the position of the detected minimum data is N in one line.
If the position of the minimum data is not at the center position (N / 2th) of the data, the detected minimum data position is the center of the area of the emboss data on the surface of the adjustment medium 2. Is used as valid data, and image processing is performed only on the valid data.

Bright output uniformity = (maximum value−minimum value) / (maximum value + minimum value) × 100% If the maximum value max is abnormal, that fact is output (steps S64 and S65), and the average value av is abnormal. If there is, that fact is output (steps S66, S67).

FIG. 7 is a graph showing the procedure for calculating the resolution, and FIG. 8 is a flowchart showing the procedure for calculating the resolution.

In the part of the reading resolution determination emboss data 24, as shown in FIG.
x and the minimum value min are searched (steps S91 and S92), and the reading resolution is calculated by the following equation (step S93).

Reading resolution = (maximum value−minimum value) / (maximum value + minimum value) × 100% After measuring the above contents with respect to these data, the image result of reading the adjustment medium 2 is printed.
The measured data is also printed at the same time, and the adjuster is notified of the mounting position and the state of the reading sensor.

FIG. 9 is a flowchart of an adjustment procedure of the reading device.

First, the adjustment medium is inhaled (step S31), and the emboss data on the adjustment medium is read (step S32).
Then, the embossed image is printed by the printing unit (step S33). Next, the center position, level, and resolution of the emboss data are calculated according to the procedures shown in FIGS. 4, 6, and 8 (step S34). Then, these calculation results are printed on the receipt (step S35). After the printed receipt is prepared for discharge (step S36),
It is discharged (step S37). Next, it is determined whether or not the adjustment has been completed (step S38).
Return the adjusting medium to the position at the time of inhalation.

On the other hand, if the adjustment has been completed,
The program is written in M (step S41), and the adjustment medium is returned (step S42). In this manner, adjustment of the center position, level, resolution, and the like can be automatically performed only by inhaling the adjustment medium.

(Effects of the Invention) As described above, according to the adjustment method of the emboss reading device of the present invention, the emboss data serving as various references is stored in the adjustment medium and read by the reading device. It is possible to measure the mounting position of the reading sensor with the medium and calculate the effective reading area by the reading device itself. Then, by registering it as an adjustment value in the battery backup memory,
Image processing of valid data can be performed based on this adjustment value. Further, once the image of the adjusting medium is read, not only the mounting position but also the white output level, bright output uniformity and reading resolution (focus) of the reading sensor when reading the reference white document can be measured. These values can then be reported to the coordinator and can be registered in the battery backup memory.

As described above, the adjuster can measure the state of the reading sensor only with the adjusting medium without using the measuring device. In addition, since no measuring device is required, not only the manufacturing stage of the reading device,
Even in a place where an automatic transaction device or the like having a reading device is installed, the operation state of the reading device can be checked and adjusted.
