Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a magnetic card reader suitable for use in devices such as an automatic fee settlement machine and an automatic teller machine, and in particular, as a magnetic card, a code number, a name, or a company name on the card surface. The present invention relates to a magnetic card reader suitable for use in various devices using a so-called embossed card formed with embossed characters and various patterns.
[0002]
[Prior art]
A general magnetic card used in various devices as described above has a magnetic stripe formed on the right side of the surface with respect to the insertion direction, and the magnetic card is inserted according to the directions of the arrows printed on the card surface. When inserted into the insertion slot of the card reader, the transport device transports the magnetic card along the card travel path, and the magnetic head provided on the upper right side of the card travel path contacts the magnetic stripe during the transport. The magnetic information is read / written.
[0003]
However, when the direction of the magnetic card is not sufficiently confirmed because it is dark or when you are in a hurry, it is often the case that you insert it in the wrong direction. A magnetic card reader that correctly reads and writes magnetic information regardless of the direction of the front and back and the front and back, that is, from four directions (the horizontal direction is handled by the size of the insertion slot), because it is complicated and time consuming. Development of was desired.
[0004]
Therefore, the present applicant, for example, as shown in Japanese Patent Application Laid-Open No. 2-168464 and Japanese Patent Application Laid-Open No. 4-302859, forms magnetic stripes of the inserted magnetic card on the upper and lower sides of the card insertion slot. A total of 2 or 4 detectors that detect and determine the front and back of the card are attached, and the left and right sides of the card transport passage for transporting the magnetic card inserted into the insertion slot are configured to be reversible by a motor. When the up-and-down direction of the magnetic head attached to each of these inversion plates does not match the orientation of the front and back of the inserted magnetic card, the above motor inverts the inversion plate and We have developed a magnetic card reader that can be inserted in four directions by configuring the magnetic stripe to read and write magnetic information with a magnetic head.
[0005]
[Problems to be solved by the invention]
However, all of the conventional magnetic card readers described above can be used without any difficulty when using a general magnetic card having only a magnetic stripe. For example, a card such as a credit card such as a bank card can be used. In the case of a magnetic card having a magnetic stripe and an embossed portion on the surface, the portion where the emboss is formed is thicker than the card surface on which the magnetic stripe is formed, and this emboss is opposite to the magnetic stripe. When the magnetic card is inserted into a magnetic reader having a plurality of magnetic heads, the embossed portion of the magnetic card other than the magnetic head currently reading / writing corresponding to the magnetic stripe The magnetic card hits the head, that is, the magnetic head on the opposite side that is not currently turned on. Or no longer able to pass through, since the problem of hurt magnetic head occurs when using a magnetic card embossing is formed could not card handling in four directions insertion.
[0006]
Therefore, the technical problem of the present invention is to make the embossed portion collide with the magnetic head when reading and writing magnetic information in four directions insertion even when a magnetic card having an emboss is formed as the magnetic card. The present invention also provides a magnetic card reader equipped with a magnetic head reversing function devised so that it can be performed without any trouble.
[0007]
[Means for Solving the Problems]
Means taken in the present invention to solve the above technical problems are as follows.
[0008]

[0011]
According to the means according to claim 1 described in the above (1), regardless of the insertion direction of the magnetic card, the insertion direction is detected and either the left or right magnetic head is reversed in the direction of the magnetic stripe. Magnetic information can be read and written with two magnetic heads for inserting the direction, and even if the magnetic card is an embossed magnetic card with embossing, the opposite side when reading and writing the magnetic stripe is used. Since the magnetic head does not exist in the embossed passage area, the emboss collides with the magnetic head and the card cannot be fed or the magnetic head is not damaged, and the magnetic information can be read and written smoothly. Allowing you to proceed.
[0012]
Further , according to the means according to claim 1 described in the above (1), since the left and right magnetic heads are mounted with phases different from each other by 90 degrees, one of the magnetic heads is attached. When reading or writing to the magnetic stripe, the other magnetic head is always retracted 90 degrees upward or downward, so the emboss of the magnetic card collides with the retracted magnetic head. This makes it possible to carry out the card smoothly.
[0013]
According to the means according to claim 2 described in the above (2) , the magnetic card is read and written to the magnetic stripe while the magnetic card is inserted between the magnetic head and the head roller. It makes it possible to read and write information in a stable state.
[0014]
As described above, the technical problems described above can be solved by the means (1) and (2) , and the problems of the conventional techniques can be solved.

When 7D is driven and rotated by the card transport motor 7M, the card transport belt 7V is operated to transport the magnetic card CK inserted into the insertion slot 1T.
[0019]
5R and 6R are left and right reversing plates mounted on the inner side surfaces of the left and right seat plates 1A and 1A so as to be able to rotate freely. 5A and 6A are rotating parts. Guide grooves for guiding both side edges of the magnetic card CK conveyed by the card conveying belt 7V on the inner surface of each of the reversing disks 5R and 6R by the left and right head reversing motors that rotate simultaneously and individually. 5H and 6H are recessed in a substantially cross shape.
[0020]
The left and right magnetic heads 5 and 6 are attached to the inner side surfaces of the left and right reversing plates 5R and 6R with phases different from each other by 90 degrees. The magnetic roller CK is a head roller that is mounted with an interval through which the magnetic card CK is inserted. The magnetic card CK is provided with guides 6H or 5H that are recessed in the left and right reversing plates 5R and 6R according to the movement of the conveying belt 7V. While being guided, a portion of the magnetic stripe ST is inserted between the magnetic head 5 or 6 and the head roller 5S or 6S to read / write magnetic information with respect to the magnetic stripe ST.
[0021]
The state shown in FIG. 2 shows a state when the detector 4 in the upper right detects that the magnetic card CK has been inserted with its magnetic stripe ST in the upper right as shown in FIG. When a detection signal is sent from the upper right detector 4, the left and right reversing motors 5M and 6M are driven so that the left and right reversing disks 5R and 6R have a phase angle of 90 degrees between the two magnetic heads 5 and 6. The magnetic heads 5 and 6 are rotated as they are maintained, and the magnetic heads 5 and 6 are in the state shown in the drawing, that is, the magnetic head of the magnetic card CK that is sent in is positioned with the right magnetic head 6 positioned directly above the transfer line of the magnetic card CK. The structure is such that magnetic information is read / written on the stripe ST.
[0022]
During this read / write operation, the left magnetic head 5 that is not related to the read / write operation is positioned 90 degrees upward to avoid collision with the embossed portion EB. The magnetic card CK can be transported and read / written without any trouble without damaging the magnetic head 5.
[0023]
In addition, when the magnetic card CK is inserted with the magnetic stripe ST in the upper left (the state in which the front and rear are reversed as in FIG. 1) and the upper left detector 3 detects the magnetic stripe ST, The reversing motors 5M and 6M rotate the left and right reversing disks 5R and 6R 90 degrees counterclockwise from the state of FIG. 2 so that the left magnetic head 5 is positioned immediately above the conveying line of the magnetic card CK. 6 can be moved to the lower 90 ° position on the lower side of the transport line to enable reading / writing of magnetic information to / from the magnetic stripe ST and to avoid collision between the embossed portion EB and the right magnetic head 6. it can.
[0024]
Similarly, when the lower right detector 4 'detects the magnetic stripe ST, the reversing motors 5M and 6M rotate the reversing plates 5R and 6R 180 degrees counterclockwise from the state of FIG. The head 6 can be positioned in a readable / writable state immediately below the magnetic card CK conveyance line, and the left magnetic head 5 can be rotated to avoid the above-mentioned line at a position 90 degrees below the line. When the device 3 'detects the magnetic stripe ST, the reversing motors 5M and 6M rotate the reversing plates 5R and 6R 90 degrees clockwise from the state of FIG. 2, and the left magnetic head 5 is moved to the magnetic card CK. The right magnetic head 6 is positioned so as to be readable / writable immediately below the transport line, and the right magnetic head 6 is rotated around the line 90 degrees above the line.
[0025]
Next, the above operation will be described with reference to the flowchart shown in FIG. 3. When the card detection sensor 1S detects the magnetic card CK inserted into the insertion slot 1T in the first step S1, the process proceeds to the next step S2 to carry the card. The motor 7M is rotated to start card conveyance, and then the process proceeds to the next step S3 to determine whether or not the upper right detector 4 (pre-head) has detected the magnetic stripe ST, and if YES, the next step In S4, the right magnetic head 6 reads / writes magnetic information. If NO, the process proceeds to Step S5.
[0026]
In step S5, it is determined whether or not the lower right detector 4 'has detected the magnetic stripe ST. If YES, the process proceeds to step S6 and the reversing motors 5M and 6M turn the reversing disks 5R and 6R in FIG. Then, after rotating 180 degrees in the counterclockwise direction, the process proceeds to step S4 to read / write magnetic information by the right magnetic head 6. If NO, the process proceeds to step S7.
[0027]
In step S7, it is determined whether or not the upper left detector 3 has detected the magnetic stripe ST. If YES, the process proceeds to step S8 where the reversing motors 5M and 6M counter the reversing plates 5R and 6R in FIG. After rotating 90 degrees in the clockwise direction, the process proceeds to step S4 and the magnetic information is read / written by the left magnetic head 5, but if NO, the process proceeds to step S9.
[0028]
In step S9, it is determined whether or not the lower left detector 3 'has detected the magnetic stripe ST. If YES, the process proceeds to step S10 and the reversing motors 5M and 6M turn the reversing disks 5R and 6R in FIG. After rotating 90 degrees in the clockwise direction, the process proceeds to step S4 to read / write magnetic information by the left magnetic head 5, but if NO, the process returns to step S3 and repeats the process. It is made up.
[0029]
Therefore, according to the magnetic card reader having the magnetic head reversing function according to the present invention, the magnetic heads 5 and 6 can be rotated in response to the insertion of the magnetic card CK in four directions. When the magnetic information is read / written by 6 or 6, the other magnetic head 5 or 6 that is not used for read / write is rotated around the magnetic card CK so that it is embossed on the magnetic card CK to be used. Even if the portion EB is formed, the card can be conveyed without any trouble without causing the other magnetic head 5 or 6 to collide with the embossed portion EB.
[0030]
In the illustrated embodiment, the left and right reversing plates 5R and 6R are reversed by different reversing motors 5M and 6M, respectively, but the phases of the left and right magnetic heads 5 and 6 are 90 as illustrated. In the case where the magnetic heads 5 and 6 are connected to each other with a shift, the magnetic heads 5 and 6 can be rotated 90 degrees, 180 degrees, and -90 degrees by one reversing motor.
[0031]
Further, as shown in the figure, the left and right reversing disks 5R, 6R are controlled and rotated in different directions by different reversing motors 5M, 6M, respectively, so that one of the necessary magnetic heads 5 or 6 is brought into a position where it can be read / written. The other magnetic head 5 or 6 that is not required may be set so as to avoid and rotate to an arbitrary angular position on the upper side or the lower side, and the selection is optional.
[0032]
Furthermore, in the above-described embodiment, the state of the reversal rotation of the magnetic heads 5 and 6 with respect to the four-direction insertion is the state shown in FIGS. 1 and 2, that is, the magnetic stripe ST on the upper right is the right magnetic head 6. However, this is for convenience only, and the magnetic heads 5 and 6 are not necessarily stopped at the angular positions shown in FIG. Since there is no limitation, the reversing motors 5M and 6M are controlled and rotated to an optimum direction and angle in accordance with the insertion posture of the magnetic card CK each time, and each magnetic head 5 and 6 is read / written with magnetic information. Of course, the position and the avoidance position are reversed and set.
[0033]
【The invention's effect】
As described above, according to the magnetic card reader having the magnetic head reversing function according to the present invention, the magnetic information is stable with respect to the magnetic stripe corresponding to the card insertion in four directions by the two magnetic heads. However, in the present invention, the other magnetic head, which is not used for read / write, of the two magnetic heads is rotated around the card conveying line so as to avoid rotation. Even if the emboss is formed on the magnetic card, this emboss does not collide with the other magnetic head, so that card feeding and reading / writing of magnetic information can be performed without any trouble, It is possible to provide a magnetic card reader that can handle card insertion in four directions even when the magnetic card has embossing.
