Description

  The present invention relates to a magnetic information reading mechanism for reading magnetic information from a magnetic medium.

  Some magnetic information reading mechanisms are configured to be able to read magnetic information from a magnetic medium formed in a booklet shape such as a bankbook (for example, see Patent Document 1). Such a magnetic information reading mechanism is mainly used in equipment used in financial institutions, such as a passbook / book entry machine, an automatic transaction apparatus (ATM), a window apparatus, and the like.

  FIG. 7 shows a configuration example of the magnetic information reading mechanism. FIG. 7 is a schematic explanatory diagram of a conventional magnetic information reading mechanism. FIG. 7A shows the configuration of the magnetic information reading mechanism viewed from above, and FIG. 7B shows the configuration of the magnetic information reading mechanism viewed from the lateral direction. In FIG. 7B, the symbol “l1” represents the length of the magnetic stripe 221 of the second medium 200b described later. Reference numeral “LL1” represents a movable range of a magnetic head 4 described later, and reference numeral “LL2” represents a range in which magnetic information can be read (hereinafter referred to as “reading range”). .

  As shown in FIG. 7, in the magnetic information reading mechanism 50, a transport path 8 for transporting the magnetic medium 200 is formed by the transport upper guide 5 and the transport lower guide 6. A magnetic medium 200 is inserted into the transport path 8 by the user from the insertion port 9 when reading magnetic information. Here, it is assumed that “passbook” is inserted as the magnetic medium 200.

  The transport upper guide 5 is provided with a transport roller 2 that is rotationally driven by a drive mechanism (not shown). On the other hand, the conveyance lower guide 6 is provided with a pressure roller 3 that rotates following the rotation of the conveyance roller 2. The pressure roller 3 is moved upward by a moving mechanism (not shown) so as to be in close contact with the transport roller 2 or downward so as to be separated from the transport roller 2.

  The conveyance roller 2 conveys the magnetic medium 200 to a predetermined reading position by being rotationally driven while sandwiching the magnetic medium 200 inserted into the conveyance path 8 with the pressure roller 3. The “reading position” is a stop position of the magnetic medium 200 defined for reading magnetic information from the magnetic medium 200. The magnetic medium 200 is stopped in a state where it is abutted against the conveyance guide abutting surface 7 provided on the side of the conveyance lower guide 6 on the reading position, for example.

  The magnetic information reading mechanism 50 has the magnetic head 4 that moves along the arrow shown in FIG. The magnetic head 4 is normally retracted below the guide surface of the transport lower guide 6 and moves along the arrow shown in FIG. 7B when reading magnetic information. As a result, the magnetic head 4 comes into contact with the magnetic stripe (magnetic stripe 211 in the illustrated example) of the magnetic medium 200 and reads magnetic information from the magnetic medium 200.

  By the way, in the passbook which is the magnetic medium 200, as shown in FIG. 8, a magnetic stripe 211 provided in a direction intersecting with the binding 206 (hereinafter referred to as “first medium 200a”), FIG. As shown in FIG. 3, there is a magnetic stripe 221 provided in a direction parallel to the stitch 206 (hereinafter referred to as “second medium 200b”).

  FIG. 8 is a configuration diagram of the first medium, and FIG. 9 is a configuration diagram of the second medium. FIG. 8A, FIG. 8B, and FIG. 8C show the configuration of the first medium 200a in an open page state when viewed from the front direction, the downward direction, and the right direction, respectively. On the other hand, FIG. 9A, FIG. 9B, and FIG. 9C show the configuration of the second medium 200b in an open page state viewed from the front direction, the downward direction, and the right direction, respectively.

  The first medium 200a and the second medium 200b have the same external dimensions. Further, the first medium 200a and the second medium 200b have the same width and lateral position of the magnetic stripes 211 and 221. However, the first medium 200a and the second medium 200b differ in the direction of the binding 206, the lengths of the magnetic stripes 211 and 221 and the information written in the magnetic stripes 211 and 221.

  The magnetic information reading mechanism 50 cannot determine whether the magnetic medium 200 is the first medium 200a or the second medium 200b until the magnetic information is read from the magnetic medium 200. Therefore, the magnetic information reading mechanism 50 has the second movable range LL1 and the reading range LL2 of the magnetic head 4 so that the magnetic information can be read from the magnetic medium having the longer magnetic stripe (that is, the second medium 200b). The length is set in accordance with the length l1 of the magnetic stripe 221 of the medium 200b (see FIG. 7B). Therefore, in the magnetic information reading mechanism 50, the movable range LL1 and the reading range LL2 of the magnetic head 4 are set slightly longer than the length l1 of the magnetic stripe 221 of the second medium 200b. The length l1 of the magnetic stripe 221 is also the length of the magnetic medium 200 in the vertical direction (length in the transport direction). Therefore, the magnetic information reading mechanism 50 moves the magnetic head 4 in a range longer than the longitudinal length 11 of the magnetic medium 200.

JP 2008-2226013 A

  However, in the magnetic information reading mechanism 50, since the movable range LL1 and the reading range LL2 of the magnetic head 4 are set according to the length l1 of the magnetic stripe of the second medium 200b, the first medium 200a is used as the magnetic medium 200. When used, the magnetic head 4 and the binding 206 of the first medium 200a come into contact with each other. Due to the impact at the time of contact, the first medium 200a is pressed in the F direction (see FIG. 7A) from the magnetic head 4, and as a result, the first medium 200a may be inclined in the R direction. Further, the magnetic head 4 was worn by the impact.

As described above, in the conventional magnetic information reading mechanism, when the first medium (that is, the magnetic medium provided with the magnetic stripe in the direction intersecting the binding) is used as the magnetic medium, the magnetic head and the first medium are used. There was a problem of contact with the stitches.
Thus, in the conventional magnetic information reading mechanism, the first medium is inclined or the magnetic head is worn.

The present invention has been made to solve the above-described problem , and can read magnetic information from two types of media having different magnetic stripe directions with a single magnetic head, and the magnetic head and the magnetic medium. It is a main object of the present invention to provide a magnetic information reading mechanism that is prevented from coming into contact with the seam.

To achieve the above object, the present invention provides a magnetic information reading mechanism for reading magnetic information from a magnetic medium by moving a single magnetic head so as to face a magnetic stripe provided on the magnetic medium. The magnetic medium provided in the direction in which the magnetic stripe intersects with the binding is the first medium, the magnetic medium provided with the magnetic stripe in the direction parallel to the binding is the second medium, and from the first medium to the A first reading position for reading magnetic information and a second reading position for reading the magnetic information from the second medium are defined in advance, and the first reading position is determined by the magnetic head of the first medium. It is defined at a position not in contact with the seam, when reading the magnetic information, the magnetic medium, from the set to the first reading position, the magnetic f Reading the magnetic information in de, when said magnetic medium from a read result of the first reading position is determined to be the second medium, said magnetic medium, after setting the second reading position The magnetic information is read by the magnetic head .

According to the present invention , magnetic information can be read by a single magnetic head from two types of media having different magnetic stripe directions, and contact between the magnetic head and the stitches of the magnetic medium is prevented. A magnetic information reading mechanism can be provided.

  Compared with the conventional magnetic information reading mechanism 50, the magnetic information reading mechanism 100 has the following features.

  (1) In the conventional magnetic information reading mechanism 50, the movable range LL1 and the reading range LL2 of the magnetic head 4 are set according to the length l1 of the magnetic stripe 221 of the second medium 200b (see FIG. 7B). ). On the other hand, in the magnetic information reading mechanism 100, the movable range L1 and the reading range L2 of the magnetic head 181 are the magnetic stripe of the first medium 200a so that the magnetic head 181 and the binding 206 of the first medium 200a do not contact each other. 211 is set in accordance with the length l2. That is, the magnetic information reading mechanism 100 is set such that the movable range L1 and the reading range L2 of the magnetic head 181 are slightly longer than the length l2 of the magnetic stripe 211 of the first medium 200a. Note that the length l2 of the magnetic stripe 211 is shorter than half of the longitudinal length of the magnetic medium 200 (that is, the length l1 of the magnetic stripe 221 of the second medium 200b). Therefore, the magnetic information reading mechanism 100 moves the magnetic head 181 within a range shorter than the reading range LL2 of the magnetic head 4 of the conventional magnetic information reading mechanism 50.

  (2) In the conventional magnetic information reading mechanism 50, the “reading position” is set at one place. On the other hand, the magnetic information reading mechanism 100 has a plurality of “reading positions” (in the first embodiment, two positions (refer to FIG. 3) of the first reading position and the second reading position). The “first reading position” is a stop position of the magnetic medium 200 defined for reading magnetic information from the first medium 200a. However, the magnetic information reading mechanism 100 temporarily stops all the magnetic media 200 at the “first reading position” in the first reading operation regardless of the type of the first medium 200a and the second medium 200b. The first reading position is defined as a position where the magnetic head 181 does not contact the binding 206 of the first medium 200a. The “second reading position” is a stop position of the magnetic medium 200 defined for reading magnetic information from the second medium 200b. The positional relationship between the “first reading position” and the “second reading position” will be described later with reference to FIG.

  (3) The conventional magnetic information reading mechanism 50 sets the magnetic medium 200 at a predetermined reading position in a single reading operation regardless of the types of the first medium 200a and the second medium 200b, thereby providing magnetic information. Read. On the other hand, the magnetic information reading mechanism 100 prevents the magnetic head 181 from contacting the binding 206 of the first medium 200a in the first reading operation regardless of the types of the first medium 200a and the second medium 200b. When the magnetic medium 200 is set to the first reading position, the magnetic information is read, and when it is determined from the reading result at the first reading position that the magnetic medium 200 is the second medium 200b, the second time In the reading operation, the magnetic medium 200 is set at the second reading position, and then the magnetic information is read.

<Relationship of reading position>
Hereinafter, the positional relationship of the reading positions of the magnetic information reading mechanism 100 according to the first embodiment will be described with reference to FIG. FIG. 3 is an operation explanatory diagram of the magnetic information reading mechanism according to the first embodiment. FIG. 3 shows the positional relationship of the reading positions of the magnetic information reading mechanism 100. 3A shows the reading range L2 of the magnetic information reading mechanism 100. FIG. FIG. 3B shows the positional relationship between the reading range L2 and the first reading position, and FIG. 3C shows the positional relationship between the reading range L2 and the second reading position.

  Here, as shown in FIG. 3A, the movable range of the magnetic head 181 of the magnetic information reading mechanism 100 is “L1”, and the reading range of the magnetic head 181 is “L2”. It will be explained as a thing.

  Here, the description will be made assuming that the dimensions of the first medium 200a and the second medium 200b are as follows.

  As shown in FIG. 3B, the first medium 200 a has a length of “l1” in the longitudinal direction and a length of the magnetic stripe 211 of “l2”. The distance to the front end of the stripe 211 is “l3”, the length of the blank area between the rear end of the magnetic stripe 211 and the magnetic writing area 212a is “l4”, and the magnetic writing area 212a Is “l5”. The seam 206 of the first medium 200a is provided at a distance of (l1 / 2) from the front end (or rear end) of the first medium 200a. The magnetic stripe 211 of the first medium 200a is provided at a distance of “w1” from the left end (side end) of the first medium 200a.

  On the other hand, in the second medium 200b, as shown in FIG. 3C, the length in the vertical direction and the length of the magnetic stripe 221 are “l1”, and the magnetic writing area extends from the rear end of the magnetic stripe 221. The length of the blank area up to 222a is “l4”, and the length of the magnetic writing area 222a is “l6”. The magnetic stripe 221 of the second medium 200b is provided at a distance of “w1” from the left end (side end) of the second medium 200b.

In such a positional relationship, as shown in FIG. 3B, the “first reading position” is defined as a position within the range from the stitch 206 of the first medium 200a to the front end of the magnetic stripe 211. .
That is, the “first reading position” is defined at a position represented by the following expression (1), where “lm” is the distance from the front end of the first medium 200a to the first reading position.
(L1 / 2) <lm <((l1 / 2) + l3) (1)

In addition, as shown in FIG. 3C, the “second reading position” is defined as a position where the distance from the front end of the second medium 200b is smaller than the first reading position.
That is, the “second reading position” is defined as a position represented by the following expression (2), where “ln” is the distance from the front end of the second medium 200b to the second reading position.
ln <lm (2)
However, the “second reading position” is such that an area (in the illustrated example, the magnetic writing area 222a of the second medium 200b) to be read of magnetic information is included in the reading range L2 of the magnetic head 181. Stipulated.

<Operation of magnetic information reading mechanism>
Hereinafter, the operation of the magnetic information reading mechanism 100 according to the first embodiment will be described with reference to FIG. FIG. 4 is a flowchart for explaining the operation of the magnetic information reading mechanism according to the first embodiment.

In the magnetic information reading mechanism 100, the insertion slot shutter 151 is normally closed, and the conveyance path 125 is thereby closed (see FIG. 1).
A user of the magnetic information reading mechanism 100 inserts the magnetic medium 200 into the insertion slot 127 when reading magnetic information. As a result, the magnetic information reading mechanism 100 starts a magnetic information reading operation.

  In the magnetic information reading operation, the magnetic information reading mechanism 100 first sets the magnetic medium 200 to the first reading position (see FIG. 3B) (S105). The process of S105 is performed as follows.

  That is, in the magnetic information reading mechanism 100, first, the conveyance control unit 101a (see FIG. 2) detects the insertion of the magnetic medium 200 by the insertion detection sensor 131, and in response thereto, the shutter drive mechanism 111 and the conveyance rotor. The drive mechanism 112 is operated. As a result, the shutter drive mechanism 111 opens the insertion slot shutter 151, and the transport rotor drive mechanism 112 rotates the transport roller 161 to take the magnetic medium 200 into the magnetic information reading mechanism 100.

  When the magnetic medium 200 is taken into the magnetic information reading mechanism 100, the transport control unit 101a operates the transport rotor drive mechanism 112 while detecting the travel position and travel state of the magnetic medium 200 by the travel monitoring sensor 132. Then, the magnetic medium 200 is transported to the position where the abutting block 171 is provided.

  When the magnetic medium 200 is transported to the position where the abutting block 171 is provided, the transport control unit 101a stops the rotation of the transport roller 161. Then, the conveyance control unit 101a operates the pressure roller moving mechanism 113 (see FIG. 2) to lower the pressure roller 162 so that the upper end position of the pressure roller 162 is lower than the guide surface of the conveyance lower guide 122. Move in the direction.

  When the pressure roller 162 moves, the conveyance control unit 101a operates the abutting block moving mechanism 114 to move the abutting block 171 from the initial position shown in FIG. 1 toward the conveyance guide abutting surface 126.

  When the abutting confirmation sensor 133 detects the abutting of the magnetic medium 200 against the conveying guide abutting surface 126, the conveyance control unit 101a temporarily stops the movement of the abutting block 171. Thereafter, the conveyance control unit 101a operates the abutting block moving mechanism 114 again to return the abutting block 171 to the initial position.

  When the abutting block 171 returns to the initial position, the conveyance control unit 101a operates the pressure roller moving mechanism 113 (see FIG. 2) to move the pressure roller 162 upward. As a result, the magnetic medium 200 is sandwiched between the pressure roller 162 and the transport roller 161.

When the pressure roller 162 moves upward, the transport control unit 101a operates the transport rotor drive mechanism 112 while detecting the travel position and travel state of the magnetic medium 200 by the travel monitoring sensor 132, and the magnetic medium 200 is detected. Is conveyed to the first reading position.
In this way, the process of S105 is performed.

  After the processing of S105, the magnetic information reading mechanism 100 reads magnetic information from the magnetic writing area 212a (see FIG. 3B) of the first medium 200a (S110). The process of S110 is performed as follows.

That is, in the magnetic information reading mechanism 100, the magnetic head control unit 101b operates the magnetic head moving mechanism 115. Thereby, the magnetic head moving mechanism 115 moves (runs) the magnetic head 181 along the arrow shown in FIG. At this time, the magnetic head 181 contacts the magnetic stripe 211 or 221 of the magnetic medium 200 and reads magnetic information from the magnetic medium 200 within the reading range L2. In the first embodiment, the magnetic head control unit 101b controls the magnetic head 181 so as to read magnetic information from the magnetic writing area 212a (see FIG. 3B) of the first medium 200a. And
In this way, the process of S110 is performed.

  Note that, as described above, the first reading position is defined as a position where the magnetic head 181 does not contact the binding 206 of the first medium 200a. For this reason, in the process of S110, the magnetic head 181 does not contact the binding 206 of the first medium 200a.

  After the process of S110, the magnetic information reading mechanism 100 determines whether or not the magnetic medium 200 is the first medium 200a by the magnetic information determination unit 101c (see FIG. 2) (S115).

  When it is determined in S115 that the magnetic medium 200 is the first medium 200a (in the case of “Yes”), the magnetic information reading mechanism 100 ends the magnetic information reading operation.

On the other hand, when it is determined in S115 that the magnetic medium 200 is not the first medium 200a (that is, the magnetic medium 200 is the second medium 200b) (in the case of “No”), the process proceeds to S120.
In this case, the magnetic information reading mechanism 100 operates in the same manner as the process of S105, and sets the magnetic medium 200 to the second reading position (S120).

  After the process of S120, the magnetic information reading mechanism 100 operates in the same manner as the process of S110 to read the magnetic information from the magnetic writing area 222a (see FIG. 3C) of the second medium 200b (S125), The magnetic information reading operation is terminated.

  When the magnetic information reading operation is completed, the magnetic information reading mechanism 100 transports the magnetic medium 200 to a predetermined predetermined operation (for example, a printing unit, a page reading unit (not shown), etc. Process).

  As described above, according to the magnetic information reading mechanism 100 according to the first embodiment, at the time of reading magnetic information, the magnetic head 181 is read regardless of the type of the first medium 200a and the second medium 200b. The magnetic medium 200 is set to the first reading position so that the magnetic medium 200 is not contacted with the stitches 206 of the first medium 200a, the magnetic information is read, and the magnetic medium 200 is read from the reading result at the first reading position. When it is determined that it is 200b, the magnetic information is read after the magnetic medium 200 is set at the second reading position in the second reading operation.

According to such a magnetic information reading mechanism 100, it is possible to prevent the magnetic head 181 and the binding 206 of the first medium 200a from contacting each other (of course, the binding 206 of the second medium 200b).
As a result, according to the magnetic information reading mechanism 100, it is possible to prevent the first medium 200a from being inclined and the magnetic head 181 from being worn.

[Embodiment 2]
In the second embodiment, when the magnetic medium 200 is the second medium 200b having a plurality of magnetic writing areas, the magnetic information reading mechanism 100 reads the magnetic information from each magnetic writing area in multiple times. It is characterized by.
In the second embodiment, the configuration of the magnetic information reading mechanism 100 is the same as that of the first embodiment (see FIGS. 1 and 2). Further, the operation conforms to the operation of the first embodiment (see FIG. 4).

  Hereinafter, the details of the second embodiment will be described with reference to FIGS. 5 and 6. 5 and 6 are operation explanatory views of the magnetic information reading mechanism according to the second embodiment, respectively.

  FIG. 5 shows a configuration of the second medium 200b having a plurality of magnetic writing areas (in the illustrated example, two locations of the magnetic writing area 222a and the magnetic writing area 222b). In the example shown in FIG. 5, in the second medium 200b, the length of the blank area between the magnetic writing area 222a and the magnetic writing area 222b is “l7”, and the length of the magnetic writing area 222b. Is “l8”, and the length of the blank area between the magnetic writing area 222b and the front end of the magnetic stripe 221 is “l9”. In the example shown in FIG. 5, the length l6 of the magnetic writing area 222a is drawn so as to be longer than the length l8 of the magnetic writing area 222b. Also, the number of magnetic writing areas can be three or more.

  FIG. 6A shows the reading range L <b> 2 of the magnetic information reading mechanism 100. FIG. 6B shows the positional relationship between the reading range L2 and the first reading position when magnetic information is read from the magnetic writing area 222a, and FIG. 6C shows the magnetic relationship from the magnetic writing area 222b. The positional relationship between the reading range L2 and the second reading position when reading information is shown.

The magnetic information reading mechanism 100 moves the magnetic medium 200 (here, the second medium 200b) as shown in FIG. 6B in the first reading operation (that is, the processing of S105 and S110 shown in FIG. 4). At the first reading position, the magnetic information written in the magnetic writing area 222a is read.
Thereafter, the magnetic information reading mechanism 100 performs the determination of S115 shown in FIG. 4 (that is, determination of whether or not the magnetic medium 200 is the first medium 200a).
Then, the magnetic information reading mechanism 100 determines in S115 that the magnetic medium 200 is not the first medium 200a (that is, the magnetic medium 200 is the second medium 200b) (in the case of “No”). In the second reading operation (that is, the processing of S120 and S125 shown in FIG. 4), as shown in FIG. 6C, the magnetic medium 200 (here, the second medium 200b) is set at the second reading position. Then, the magnetic information written in the magnetic writing area 222b is read.

  The magnetic information reading mechanism 100 preferably has the position of the second reading position or the number of readings so that the magnetic information can be read from all the magnetic writing areas when there are three or more magnetic writing areas. It may be set in advance.

  As described above, according to the second embodiment, magnetic information is read from each magnetic writing area in a plurality of times. Thus, according to the second embodiment, the length 11 (see FIG. 6B) of the magnetic stripe 221 is longer than the length 12 (see FIG. 3B) of the magnetic stripe 211 of the first medium 200a. Even for the second medium 200b, the reading range L2 of the magnetic head 181 can be set in the same manner as when reading magnetic information from the first medium 200a. Therefore, according to the second embodiment, the magnetic information reading mechanism 100 can be downsized.

  The present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the gist of the present invention.
