Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a card transport apparatus that is internally configured in an IC card reader of, for example, an automatic transaction machine, and more specifically, a card transport apparatus that can accurately determine a card transport stop position and perform accurate data processing. About.
[0002]
[Prior art]
In general, this type of card transport device performs magnetic data processing, punch hole processing, printing processing, etc. on a card, so that it is required to accurately stop the transport of the magnetic card to a predetermined data processing position. The magnetic card guided on the road is detected by a card detection sensor, and the output of the transfer motor is controlled based on the detection signal to stop the transfer of the magnetic card to a fixed position.
[0003]
[Problems to be solved by the invention]
However, depending on the surrounding temperature environment, the card conveying member such as a rubber roller expands or contracts to change the outer diameter, and the card feed amount fluctuates accordingly, processing of magnetic data to the card, punch hole processing, etc. In some cases, data processing such as printing processing cannot be accurately performed with a deviation from a fixed position on the card surface.
[0004]
Similarly, when the IC card is positioned at a fixed position by the IC card reader, the leading edge or the trailing edge of the IC card is similarly detected by the card detection sensor, and the IC card is stopped from being transported to the fixed position based on the detection signal. Therefore, in order to position the IC card in a fixed position, a card detection sensor is always required. Therefore, when the number of positioning is large, many card detection sensors must be arranged in proportion to this, Further, when changing the card stop position, it is necessary to change the arrangement of the card detection sensor, which is troublesome and cannot be easily changed.
[0005]
It is also possible to position using a card detection sensor and motor encoder, or add a timer function, but in this case, when the card slips or transport irregularities occur due to speed fluctuations. However, the accuracy of the card stop position for stopping the card at the regular position is poor and the card cannot be positioned correctly.
[0006]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a card transport apparatus that can accurately stop and transport a card to a predetermined data processing position, and can easily change the setting of the stop position.
[0007]
[Means for Solving the Problems]
The invention according to claim 1 is a card transport device that transports a card to a fixed position on the transport path to process data, a card position detection sensor that detects the current position of the card, and a width direction of the transport path. A roller arranged in a substantially central portion and rotating around the card surface; an encoder fixed to the same shaft as the roller and detecting the travel distance of the card directly based on the rotation amount of the roller; and the card position A stop position determining means for determining a stop position of the card based on the output signal of the detection sensor and the output signal of the encoder is provided.
[0008]
The invention according to claim 2 is characterized in that the card position detection sensor and the roller are arranged at substantially the same position in the transport direction of the transport path.
[0009]
[Action and effect of the invention]
According to the present invention, the travel distance of the card is directly determined by the output signal of the card position detection sensor that detects the current position of the card and the roller that rotates around the card surface at the approximate center in the width direction of the transport path. Based on the output signal of the encoder to be detected, it is possible to accurately determine the travel distance of the card actually traveled from the position of the card before travel, so the current position of this card is accurately identified and card transport is stopped. The position can be accurately determined by the stop position determining means.
[0010]
As a result, since the card can be accurately positioned at the stop position and the conveyance can be stopped, the card can be accurately positioned at a predetermined position to perform accurate data processing. Further, when changing the card stop position, it is possible to arbitrarily set the card conveyance stop position to be changed because it is possible to measure the exact movement distance by directly contacting the card. For this reason, the card stop position can be changed without requiring a structural change, and a highly accurate card transport stop function can be obtained with a simple structure. Further, even if card conveyance unevenness occurs on the card conveyance path, it is possible to accurately detect the position of the card and correctly position it at a regular stop position.
[0011]
Furthermore, the card position detection sensor and the roller are arranged at substantially the same position in the transport direction of the transport path, thereby facilitating accurate measurement of the moving distance, and even when the card stop position is changed. Positioning can be performed accurately.
[0012]
【Example】
An embodiment of the present invention will be described below in detail with reference to the drawings.
FIG. 1 shows an IC card reader 11, which is provided with a card transport path 15 for holding and transporting an IC card 14 in a horizontal direction inwardly communicating with a card insertion slot 13 of a card reader body 12. A magnetic data processing unit 16, an IC data processing unit 17, and an encoder 18 are arranged on the card transport path 15.
[0013]
The above-described card transport path 15 is provided with a plurality of pairs of sandwiching transport rollers R and a plurality of card position detection sensors S that are vertically opposed to each other along the transport direction, and the card is inserted based on the drive of the transport motor M. The IC card 14 inserted into the slot 13 is taken inward and guided to the magnetic data processing unit 16 and the IC data processing unit 17. After the prescribed data processing is performed on the IC card 14, the card is inserted backward and then inserted into the card insertion slot. 13 is returned. In addition, a card width detection switch 13a, a magnetic stripe detection head 13b, and a shutter 13c are disposed near the inner side of the card insertion slot 13 to manage the proper use of the IC card 14.
[0014]
The magnetic data processing unit 16 is provided with a head-corresponding roller 16a and a magnetic head 16b on the upper and lower positions across the card transport path 15, and performs magnetic data processing on the IC card 14 guided here.
[0015]
The IC data processing unit 17 arranges an IC card contact mechanism 19 for bringing the IC contact into contact with the contact of the IC card 14 led here, and performs IC data processing on the IC card 14.
[0016]
As shown in FIG. 3, the encoder 18 is in contact with the upper surface of the IC card 14 led to the central portion in the width direction of the card transport path 15 having the card transport width between the left and right frames 15a and 15b. The encoder roller 20 that rotates is disposed, the encoder plate 22 is attached to the other end of the rotating shaft 21 that rotates integrally with the encoder roller 20, and the amount of rotation of the encoder plate 22 is detected and measured. The conveyance distance can be obtained by actual measurement.
[0017]
Therefore, if the current position of the IC card 14 is obtained by the card position detection sensor S... Disposed on the card conveyance path 15 and the conveyance distance of the IC card 14 is obtained by the encoder 18, the vehicle actually travels from the card detection position. Therefore, if the output of the transport motor M is controlled, the IC card 14 can be accurately positioned and stopped at the transport stop position.
[0018]
FIG. 4 shows a card stop mechanism 41. The card stop mechanism 41 sends the output of the transport motor M to the drive side of the card transport path 15 via a drive belt B1 and a driven belt B2 stretched between pulleys P (see FIG. Power is transmitted to the nipping and conveying rollers R on the middle and lower side, and the IC card 14 is conveyed in the take-in direction or the return direction based on the forward / reverse drive of the conveyance motor M. Stop feeding accurately at the position.
[0019]
The IC card stop control at this time is
L: Distance from the detection position of the card to the stop position π: Circumference r: Radius of the encoding roller X: Number of output signals from the encoder when the IC card moves n: Number of output signals per rotation of the encoding roller When
L = 2πrX / n
Is required.
[0020]
Even when the position of the IC data processing unit 17 is changed on the card transport path 15, the encoding roller 20 is in close contact with the upper surface of the IC card 14 and is in direct rolling contact with the card 14. Since the movement distance can be accurately measured as the amount of roller rotation, the conveyance stop position of the card 14 to be changed can be freely set, and in particular, the card can be conveyed without requiring structural changes such as changing the sensor position. The stop position can be changed.
[0021]
FIG. 5 shows a control circuit block diagram of the IC card reader 11. The CPU 51 controls each circuit device in accordance with a program stored in the ROM 52 and stores the control data in a readable manner by the RAM 53. Further, the shutter solenoid SOL is driven by a control signal of the CPU 51 to control opening / closing of the shutter 13c of the card insertion slot 13.
[0022]
Next, the IC card processing operation of the IC card reader 11 configured as described above will be described.
Now, when the IC card 14 is inserted into the card insertion slot 13, the CPU 51 drives the transport motor M to take in and transport the inserted IC card 14 onto the card transport path 15 at a constant speed. When the magnetic data processor 16 passes through the position of the magnetic data processor 16, the magnetic stripe of the card 14 contacts the magnetic head 16 b and magnetic data processing is performed. Thereafter, the IC card 14 is transferred to the inner IC card processor 17. Led.
[0023]
At this time, the CPU 51 obtains the current position of the IC card 14 conveyed on the card conveyance path 15 by each of the card position detection sensors S arranged at a plurality of locations on the card conveyance path 15, and further the IC card 14 conveyed. The encoder roller 20 is in contact with the upper surface of the IC card 14 to obtain the actually measured card conveyance distance from the encoder 18, and the movement distance in which the IC card 14 is actually conveyed is accurately calculated based on the current position of the IC card 14 being conveyed. Based on this, the CPU 51 accurately determines the transport stop position of the IC card 14, stops the transport of the card 14 accurately at the data processing position of the IC data processing section 17, and the IC data is detected at the proper data processing position. Execute the process. For this reason, even if the IC card 14 is unevenly transported on the card transport path 15, the IC card 14 is correctly transported and stopped at the proper stop position, and the IC card 14 is always subjected to accurate data processing. Can do.
[0024]
Then, after the IC data processing, the card transport path 15 is reversely sent to return the data-processed IC card 14 to the card insertion slot 13 to confirm that the IC card 14 has been removed. One transaction ends.
[0025]
Further, when changing the transport stop position of the IC card 14, the card detection sensor S accurately detects and confirms the position of the IC card 14, and measures the contact with the surface of the IC card 14 to which the encode roller 20 is transported. Therefore, the movement distance of the IC card can be accurately measured, and the setting can be arbitrarily changed to the conveyance stop position of the IC card to be changed. For this reason, the IC card stop position can be changed without requiring any change in the internal structure such as a change in the sensor position.
[0026]
As described above, based on the output signal of the card position detection sensor that detects the current position of the IC card and the output signal of the encoder that directly contacts the IC card surface and directly detects the travel distance of the IC card, Since the movement distance of the IC card actually traveled can be obtained accurately from the position of the IC card, the current position of the IC card can be accurately identified and the IC card conveyance stop position can be accurately determined by the CPU. Can do.
[0027]
Therefore, accurate data processing can be performed by accurately positioning the IC card at the position of the IC data processing unit. Further, when changing the IC card stop position, the exact moving distance can be measured by directly contacting the IC card, so that the IC card transport stop position to be changed can be freely set and changed. For this reason, the stop position of the IC card can be changed without requiring a structural change such as a change of the sensor position, and a highly accurate IC card transport stop function can be obtained with a simple structure. Further, even if the IC card is unevenly transported on the card transport path, the position of the IC card can be accurately detected and correctly positioned at the proper stop position.
