Description

  The present invention relates to a cleaning pad for a magnetic head and a magnetic stripe processing device built in a passbook processing machine such as a passbook printing mechanism and a passbook issuing device provided in an automatic teller machine.

Generally, when processing passbook magnetic data in a passbook processor, the magnetic data of the magnetic stripe is read and written by running the magnetic head in contact with the magnetic stripe of the passbook to process the magnetic data. Yes.
If foreign matter such as paper dust adheres to the magnetic contact surface of the magnetic head, the output level of magnetic data is lowered, causing a magnetic data processing failure, resulting in a failure of transaction. For this reason, it was necessary to periodically clean the magnetic contact surface of the magnetic head.

  The cleaning of the magnetic head is preferably automated. As an example, a cleaning pad (cleaning cloth) is attached on the traveling path of the magnetic head, and when the traveling magnetic head comes into contact with the cleaning pad, the magnetic head is cleaned. A magnetic head cleaning mechanism that automatically removes dirt has been proposed (see, for example, Patent Document 1).

  However, the magnetic contact surface of the magnetic head comes in contact with the same surface as the magnetic stripe of the passbook, so local wear occurs. When this local wear increases, foreign matter such as paper dust and dust tends to adhere. The magnetic data processing performance deteriorates, and the transaction failure of the passbook often occurs. For this reason, the magnetic head has reached the end of its life when local wear increases.

Here, the result of considering the problem that the life of the magnetic head cannot be extended will be described in detail with reference to FIGS.
First, as shown in FIG. 10A, in the magnetic processing mechanism that travels with the magnetic head 102 in contact with the magnetic stripe 101 of the passbook P, as shown in FIG. The magnetic head 102 reads and writes the magnetic data of the magnetic stripe 101 when it travels in contact with the magnetic stripe 101, and this magnetic data processing is repeatedly executed for each transaction of the bankbook P.

  Therefore, the magnetic contact surface 102a of the magnetic head 102 is gradually worn away when used for a long period of time, and a concave portion (air gap) 103 having a step shape in the shape of a concave groove is formed. In this dent 103, a highly sticking foreign matter 104 such as paper dust or dust enters, adheres and accumulates. Thereby, the magnetic processing performance of the magnetic contact surface 102b in the recess 103 is lowered and poor contact with the magnetic stripe 101 occurs. In other words, the output level of the magnetic data is lowered due to the formation of the step in the recess 103, and a magnetic data processing failure of the magnetic stripe 101 occurs.

  For this reason, the foreign matter 104 adhering to the magnetic contact surface 102a of the magnetic head 102 may be removed. As the foreign matter removing means, as shown in FIGS. 11A and 11B, a cleaning pad 106 is disposed on the traveling path of the magnetic head 102, and the cleaning pad 106 is moved when the magnetic head 102 travels in the arrow direction 105. 106 removes the foreign matter 104. As shown in FIG. 11C, the cleaning pad 106 used here forms a sharp edge 107 at a rectangular corner, and the edge 107 is disposed at a height position along the magnetic contact surface 102a. It is dealt with by.

  When the magnetic head 102 travels in the arrow direction 108 shown in FIG. 12 (A), the foreign matter 104 adhering to the magnetic contact surface 102a of the magnetic head 102, as shown in FIG. 12 (B), It is scraped off by the edge 107 of the cleaning pad 106.

  Further, the magnetic head 102 travels in the arrow direction 109, and when the magnetic head 102 passes through the contact position with the cleaning pad 106, as shown in FIG. 12C, the surface layer accumulated on the upper surface of the magnetic head 102. The foreign matter 104 is removed by the edge 107 of the cleaning pad 106.

  However, since the edge 107 of the cleaning pad 106 cannot enter the recess 103 with respect to the inner layer foreign matter 110 that has entered the recess 103 of the magnetic head 102, the inner layer foreign matter 110 cannot be completely removed. As a result, the magnetic performance of the magnetic head 102 is deteriorated.

  For this reason, as an example of cleaning the dents (dents), a special cleaning card is used, and the “file-like grooves” and “holes” formed on the surface of the card are warped. There has been proposed a dry magnetic head cleaning card that protrudes like a bow and scrapes out foreign matter accumulated in the recess at the protruding edge portion (see, for example, Patent Document 2).

  However, when the magnetic contact surface of the magnetic head is cleaned using the dry magnetic head cleaning card, it is necessary for an attendant or maintenance staff to introduce the cleaning card into the passbook processor as a maintenance operation for cleaning the magnetic head. It was. In addition, it does not automatically clean in the transaction process of the passbook, it uses a cleaning card periodically, and it takes time and effort to do it manually, and there is an automatic transaction machine such as an automatic teller machine. Had a problem that the operation had to be interrupted every time the magnetic head had to be cleaned.

The drawing shows a magnetic head cleaning pad provided in a magnetic stripe processing apparatus of a passbook printing mechanism, showing an embodiment in which the cleaning performance of the magnetic head is enhanced.

  FIG. 1 shows a passbook printing mechanism 12 having a magnetic stripe processing apparatus 11 according to an embodiment of the present invention. The passbook printing mechanism 12 has a passbook insertion port 14 for inserting the passbook P on the front surface of the printing mechanism main body 13, and a passbook transport path 15 for horizontally transporting the passbook P inwardly communicating with the passbook insertion port 14. Is provided. A magnetic stripe processing device 11, an image reader 16, a passbook printing unit 17, and a page turning mechanism unit 18 are arranged in this order along the passbook transport path 15.

  FIG. 2 shows the magnetic processing state of the passbook P guided to the magnetic stripe processing device 11. In the magnetic stripe processing device 11 on the passbook transport path 15, the passbook P is transported on the opposite side across the transport width of the passbook P. A conveyance reference plate 21 serving as a reference surface is opposed, and a width guide plate 22 that presses the passbook P against the conveyance reference plate 21 is provided on the other side opposite to the conveyance reference plate 21.

  At the position of the magnetic stripe processing device 11, the passbook P is inserted into the passbook insertion port 14 with the printed page opened upward, and the inserted passbook P stops being conveyed at the processing position of the magnetic stripe processing device 11. Is done. Then, the bankbook P is subjected to magnetic data processing by the magnetic head 25 in a conveyance stopped state.

  The bankbook P is provided with a magnetic stripe 23 on which magnetic data is recorded and a bar code 24 representing page information of the bankbook P. The magnetic stripe 23 is provided on the lower surface of the bankbook P, and the traveling path 27 of the magnetic head 25 is opposed to the lower position facing the magnetic stripe 23. The magnetic head 25 is shown in FIG. As indicated by the arrow, the vehicle travels in the magnetic head travel direction 26. At this time, the passbook data of the magnetic stripe 23 is read and written by magnetism. At the position of the magnetic stripe processing device 11 of the bankbook P, there is an arrangement relationship in which the longitudinal direction of the magnetic stripe 23 is arranged orthogonal to the bankbook transport direction. When the magnetic head 25 travels in contact with the magnetic stripe 23 at this magnetic data processing position, the magnetic data of the magnetic stripe 23 is processed.

  Further, the barcode 24 positioned on the upper surface of the opened page is read by the image reader 16. Further, the transaction information is printed in the printing field of the passbook P by the passbook printing unit 17 at the subsequent stage, and the page turning mechanism unit 18 appropriately performs the page turning operation.

  FIG. 3 is a perspective view specifically showing the magnetic head traveling mechanism 31 of the magnetic stripe processing apparatus 11. The magnetic head travel mechanism 31 includes a carrier 33 slidably supported by a travel guide shaft 32 installed along the magnetic head travel direction 26 and a wire disposed at one end of the carrier 33 in the slide direction. It comprises a driving pulley P1 and a carrier driving wire 34 stretched between a wire driven pulley P2 disposed at the other end.

  In the magnetic head traveling mechanism 31, each traveling component is supported by a frame body 35 that is long along the traveling direction. At one end of the frame body 35, a magnetic head drive motor 36 serving as a drive source for the magnetic head traveling mechanism 31 is disposed. When the magnetic head drive motor 36 is driven, the power is transmitted to the carrier 33 through the wire 34. The carrier 33 holds the magnetic head 25, and the carrier 33 that receives power in the traveling direction via the wire 34 travels on the travel guide shaft 32 together with the magnetic head 25. When the magnetic head 25 is traveling, the upper surface (magnetic contact surface 25a) of the magnetic head 25 is in contact with the lower surface (magnetic stripe 23) of the bankbook P, and read / write processing is performed on the magnetic stripe 23 (see FIG. 2).

  The magnetic head drive motor 36 is driven forward / reversely by control from a control unit (not shown). Based on this forward / reverse drive, the magnetic head 25 moves forward or backward in the horizontal direction at a constant speed, and reciprocates once with a running length that is equal to or longer than the length of the magnetic stripe 23.

  Further, in the magnetic head running direction 26, a magnetic head cleaning pad (hereinafter referred to as a cleaning pad) that performs cleaning by contacting the magnetic head 25 at the other end of the frame main body 35 that is opposite to the magnetic head driving motor 36. 37 is disposed.

  The cleaning pad 37 is attached to the traveling path 27 of the magnetic head 25 at a height in contact with the upper surface of the magnetic head 25 with respect to the magnetic head 25 arranged with the magnetic contact surface 25a (see FIG. 4) facing upward. . Specifically, a metal plate 38 is horizontally fixed to the other end of the frame main body 35 on the traveling path 27 of the magnetic head 25, and the cleaning pad 37 is attached to the lower surface of the metal plate 38 with double-sided tape, screws, or the like. Install and arrange so that the cleaning surface is facing down.

  The cleaning pad 37 is in contact with the upper surface of the magnetic head 25 at the traveling end of the magnetic head 25 that has processed the magnetic stripe 23 with magnetic data. In this contact, the cleaning pad 37 is configured to perform automatic cleaning that removes dirt adhering to the magnetic head 25.

FIG. 4 shows an enlarged view of the magnetic head 25 to be cleaned. 4A shows a side view of the magnetic head 25, and FIG. 4B shows a front view of the magnetic head 25.
The magnetic head 25 travels in the magnetic head traveling direction 26 (see FIG. 3), and the upper surface of the magnetic head 25 is formed into a mountain-shaped magnetic contact surface 25a so that stable contact can be obtained during traveling. Further, swing support protrusions 25b are projected on both sides of the magnetic head 25 as viewed from the side, and are supported on the carrier 33 so as to be swingable. By this swinging support, the magnetic head 25 is swingably supported in the conveyance width direction, and the magnetic contact surface 25a of the magnetic head 25 stably contacts the contact surface of the magnetic stripe 23 of the bankbook P.

  FIG. 5 shows a state in which the magnetic head 25 has been worn and a state in which foreign matter has adhered. FIG. 5A shows a state in which the magnetic contact surface 25a of the magnetic head 25 is worn, and FIG. 5B shows a foreign matter adhesion state in which foreign matter has adhered to the magnetic contact surface 25a of the magnetic head 25. The magnetic contact surface 25a is gradually worn by contact with the magnetic stripe 23, and only the width of the magnetic stripe is worn by long-term use, and a step is formed in the concave groove U. The concave groove U is formed with a wear surface m1 formed to be recessed in the center and a non-wear surface m2 that does not contact the magnetic stripe 23 on both sides of the concave groove U.

  At this time, the inner layer foreign matter 41 such as paper powder, metal powder, dust, and dust having high adhesiveness adheres to the worn surface m1 that is recessed corresponding to the magnetic stripe width. Similarly, the outer layer foreign matter 42 such as paper powder, metal powder, dust, and dust having high adhesiveness adheres to the non-wear surface m2. These foreign substances 41 and 42 deteriorate the performance of the magnetic head 25 and cause a magnetic data processing failure, so it is necessary to remove them quickly.

  Therefore, in order to remove these foreign substances 41 and 42, as shown in FIG. 5C, the cleaning pad 37 corresponding to the portion where the magnetic contact surface 25a is worn and becomes the concave groove U is brought into contact. Both foreign substances 41 and 42 can be efficiently removed at once.

  FIG. 6 shows an enlarged view of the cleaning pad 37. The cleaning pad 37 is composed of a small wear surface pad 37a and a non-wear surface pad 37b as a base thereof. These pads 37a and 37b can be made of a material suitable for removing foreign substances, for example, a resin material. These pads 37a and 37b are integrated and set on the traveling path 27 of the magnetic head 25 so as to be set in a direction perpendicular to the conveying direction of the magnetic head 25.

  The wear surface pad 37a is provided in a small flat plate shape having a width L1 corresponding to the width of the magnetic stripe that can enter the concave groove U of the magnetic head 25 and a slight thickness L2. Further, the wear surface pad 37a has a corner (for example, 90 degrees) on one side in the width length L1 direction which is the opposite side in the forward movement direction of the magnetic head 25 as a cleaning edge 37c for the wear surface. Parallel to the width direction, the thickness L2 is vertically provided. When the wear surface pad 37a corresponds to the magnetic head 25, the wear surface pad 37a enters the groove of the magnetic head 25, and the inner layer foreign matter 41 adhering to the groove is cleaned for the wear surface. The edge 37c is scraped and cleaned.

  The cleaning edge 37c for the wear surface is formed to be at least as short as the width of the magnetic stripe 23 or shorter. Thereby, the cleaning edge 37c for the wear surface surely enters the concave groove of the magnetic head 25 and functions as a cleaning pad dedicated to the concave groove for reliably removing the inner layer foreign matter 41.

  On the other hand, the non-wearing surface pad 37b has a horizontally long flat plate shape longer than the width of the magnetic head 25, and has a corner (for example, 90 degrees) on one side of the horizontally long direction (the side facing the forward direction of the magnetic head 25). ) Becomes the cleaning edge 37d for the non-wearing surface, and when the non-wearing surface pad 37b corresponds to the magnetic head 25, the cleaning edge 37d for the non-wearing surface is non-wearing on both sides of the groove where the magnetic head 25 is not worn. The outer layer foreign matter 42 adhering to the surface m2 is removed.

  Then, the wear surface pad 37a is formed to have a stepped structure by making the wear surface pad 37a protrude slightly from a part of the flat lower surface that becomes the cleaning surface of the non-wear surface pad 37b. As a result, the cleaning pad 37 does not contact the magnetic head 25 in the same plane, but has a two-stage contact surface structure of the wear surface pad 37a and the non-wear surface pad 37b. A two-stage contact structure in which both the (concave groove U) and the non-wear portion can be simultaneously contacted is obtained. It should be noted that the position where the wear surface pad 37a is disposed is positioned at a position corresponding to the center of the magnetic head 25 in the width direction.

  Each of the cleaning edges 37c and 37d is set to have an edge shape and an edge angle suitable for removing foreign matters attached to the magnetic head 25. For example, in addition to the flat plate-like right edge portions of the cleaning edges 37c and 37d, the edge portions may be provided on an inclined surface having a predetermined inclination angle to enhance the foreign matter removing effect.

Next, the cleaning processing operation for removing the foreign matter attached to the magnetic head 25 will be described with reference to FIG.
When the magnetic head 25 is used for a long period of time, the magnetic contact surface 25a is gradually worn by contact with the magnetic stripe 23, and a step shape of a concave groove is formed on the magnetic contact surface 25a by the wear surface m1 and the non-wear surface m2. The

  In FIG. 7A, if the magnetic head 25 is used for a long time, a groove is formed on the magnetic contact surface 25a, the inner layer foreign matter 41 adheres to the wear surface m1 of the groove, and the outer layer foreign matter 42 appears on the non-wear surface m2. In the case of the attached magnetic head 25, the magnetic head 25 travels when processing magnetic data, and is transported to the cleaning pad 37 side arranged at the end of the magnetic head traveling direction 26.

  7B, when the magnetic head 25 travels and reaches the cleaning pad 37, the magnetic head 25 comes into contact with the non-wearing surface cleaning edge 37d of the non-wearing surface pad 37b. Cleaning is started such that the cleaning edge 37d scrapes off the outer layer foreign matter 42 adhering to the non-wear surface m2 of the magnetic head 25.

  In FIG. 7C, when the magnetic head 25 further travels in the magnetic head traveling direction 26, the magnetic head 25 also contacts the wear surface pad 37a following the contact with the non-wear surface pad 37b. At this time, the wear surface pad 37a enters the groove of the magnetic head 25, and the wear surface cleaning edge 37c of the wear surface pad 37a scrapes and cleans the inner layer foreign matter 41 in the groove.

  Thereafter, when the magnetic head 25 further travels and travels to a position that has passed the cleaning pad 37 as indicated by an imaginary line in FIG. 7C, the cleaning of the magnetic head 25 is completed.

  Thus, each time the magnetic head 25 travels and magnetic data processing is performed on the magnetic stripe 23, the magnetic contact surface 25a of the magnetic head 25 contacts the cleaning pad 37 and is automatically cleaned during the traveling process. At that time, even if the magnetic contact surface 25a contacting the magnetic stripe 23 is worn and a groove is formed by the wear surface m1 and the non-wear surface m2 on the magnetic contact surface 25a, the shape depends on the shape of the groove. Since the shaped cleaning pad 37 can be brought into contact, the magnetic head 25 can be reliably cleaned regardless of the occurrence of the concave groove.

  Therefore, even if the inner layer foreign matter 41 adheres to the concave groove, it can be reliably removed. For this reason, the magnetic contact surface 25a always maintains good magnetic performance. As a result, the cleaning accuracy of the magnetic head 25 can be improved accurately, and the life of the magnetic head 25 can be reliably extended.

  In the above embodiment, the corner of one side of the cleaning pad 37 that contacts when the magnetic head 25 travels forward is used as the cleaning edge 37c, but the corner of the other side of the cleaning pad 37 that contacts when the magnetic head 25 travels backward is used. You may comprise so that it may clean as a cleaning edge.

  Further, the cleaning edge 37c on one side of the cleaning pad 37 is brought into contact with the magnetic head 25 in the forward movement, and the cleaning edge on the other side is brought into contact with the magnetic head 25 in the backward movement. The cleaning efficiency can be increased by cleaning.

  Next, when considering the durability of the cleaning pad 37 described above, the cleaning contact pressure is equal to the thickness L2 (see FIG. 6) in which the cleaning edge 37c for the wear surface protrudes from the cleaning edge 37d for the non-wear surface. Becomes higher and wears earlier than the cleaning edge 37d for the non-wear surface. For this reason, the structural example of an early wear avoiding means is demonstrated with reference to FIG.

  FIG. 8A shows an example of a highly durable cleaning pad 37 corresponding to the wide magnetic stripe 23. The cleaning pad 37 has two long and wide wear surface pads 81 arranged in the running direction of the magnetic head 25 as early wear avoiding means.

  As a result, two identical wide wear surface pads 81 are arranged in parallel in the traveling direction of the magnetic head 25. Therefore, even if the edge of one wide wear surface pad 81 is worn, the edge of the other wide wear surface pad 81 remains. Since the same cleaning function is fulfilled, the cleaning ability of the wide wear surface pad 81 can be maintained for a long period of time.

  FIG. 8B shows an example of a highly durable cleaning pad 37 corresponding to the narrow magnetic stripe 23. This cleaning pad 37 has two narrow and narrow wear surface pads 82 arranged in the running direction of the magnetic head 25 as early wear avoiding means.

  As a result, two identical narrow wear surface pads 82 are arranged in parallel in the traveling direction of the magnetic head 25, so that even if the edge of one narrow wear surface pad 82 is worn, the other narrow wear surface pad 82. Since these edges serve as a similar cleaning function, the cleaning ability of the narrow wear surface pad 82 can be maintained for a long period of time.

  FIG. 8C shows an example of a highly durable cleaning pad 37 that can be cleaned in common with two types of magnetic stripes having different magnetic stripe widths. This cleaning pad 37 is an arrangement in which two pads 81 and 82 of a wide wear surface pad 81 and a narrow wear surface pad 82 are arranged in the running direction of the magnetic head 25 as an early wear avoidance means.

  Thereby, since the two wear surface pads 81 and 82 having different widths in the running direction of the magnetic head 25 are arranged in parallel, it is possible to correspond to a plurality of passbooks having different magnetic stripe widths.

  FIG. 8D shows an example of a highly durable cleaning pad 37 that can be cleaned in common for two types of magnetic stripes having different magnetic stripe widths. This cleaning pad 37 is used as a means for avoiding early wear, and a total of four pads 83, 84 of two parallel wide wear surface pads 81 and two parallel narrow wear surface pads 82 are run of the magnetic head 25. They are arranged side by side in the direction.

  As a result, of the four wear surface pads 81 and 82 arranged in parallel, the parallel set of pads corresponds to contact with the concave groove of one magnetic head 25, so that the concave groove is reliably subjected to the cleaning process operation. Polished. Therefore, it is possible to cope with a plurality of passbooks having different magnetic stripe widths while reliably avoiding early wear.

FIG. 9 shows a cleaning pad 37 having an elastic support mechanism.
FIG. 9A shows an example of a wear surface pad structure in which the cleaning pad 37 itself has elasticity, and an inclined wear surface pad 91 in which a part of a horizontal flat-plate-like cleaning pad 37 is cut down and inclined downward is projected. Configure. The inclined wear surface pad 91 is cantilevered as an elastic support mechanism on the inclined base end side, and the inclined distal end side is allowed to be elastically displaced in the vertical direction with the cantilever support portion as an elastic fulcrum, and the inclined distal end portion is a cleaning edge for the wear surface. 91a.

  When the inclined wear surface pad 91 corresponds to the magnetic head 25, the cleaning edge 91 a for the wear surface comes into contact with the elastic head in the vertical direction so as to follow the depth of the concave groove of the magnetic head 25. Therefore, stable contact can be ensured regardless of the groove depth.

  FIG. 9B shows an example of a wear surface pad structure in which the cleaning pad 37 itself has elasticity, and a plate shape in which a part of a horizontal flat cleaning pad 37 is cut downward and protruded into a trapezoidal cross section. Alternatively, an annular elastic wear surface pad 92 is formed. The elastic wear surface pad 92 is thin and has an elastic support structure that is elastically displaced in the vertical direction. The lower end corner of the elastic wear surface pad 92 is provided on the cleaning edge 92a for the wear surface.

  When the elastic wear surface pad 92 corresponds to the magnetic head 25, the wear surface cleaning edge 92 a is elastically displaced in the vertical direction so as to follow the depth of the concave groove of the magnetic head 25 and reliably contact. Therefore, stable contact can be ensured regardless of the groove depth.

  FIG. 9C shows an example of the elastic support mechanism of the cleaning pad 37. This elastic support mechanism uses a biasing force of a coil spring 93 that expands and contracts in the vertical direction. That is, the upper end of the coil spring 93 is attached to the fixing member 94 and the lower end is attached to the cleaning pad 37.

  As a result, the cleaning pad 37 is supported so as to expand and contract in the vertical direction. When the magnetic head 25 is guided to the position of the cleaning pad 37, the cleaning pad 37 elastically corresponds to the cleaning pad 37 that contacts the upper surface of the magnetic head 25. Sometimes, the cleaning pad 37 can be brought into contact with the magnetic head 25 in the depth direction of the concave groove with certainty. Therefore, stable contact can be ensured regardless of the depth of the groove or the inclination of the magnetic head 25.

  As described above, even if the magnetic contact surface 25a of the magnetic head 25 is worn, the cleaning pad 37 corresponding to the concave groove U shape of the worn wear surface comes into contact and cleans, so the magnetic contact surface 25a is worn. Substantially complete cleaning corresponding to the concave U shape is possible. Therefore, even if the cleaning of the magnetic head 25 is automated, the entire surface of the wear surface m1 in the concave groove of the magnetic contact surface 25a and the non-wear surface m2 on both sides thereof can be reliably cleaned. As a result, the magnetic head 25 can maintain a stable magnetic processing performance without lowering the magnetic performance. Further, since the cleaning operation of the magnetic head 25 is executed every time the magnetic head 25 is run, the magnetic contact surface 25a is always free of foreign matter, so that stable magnetic performance can be secured and the life of the magnetic head 25 can be extended. it can. Even if foreign matter is attached to the magnetic contact surface 25a, the foreign matter attached by the running operation of the magnetic head 25 can be immediately removed. As a result, the worn groove U of the magnetic head 25 is also reliably cleaned, and the manual cleaning work can be reduced and maintenance-free can be realized.

  The present invention is not limited to the configuration described in the above-described embodiments, and can be applied based on the technical idea described in the claims. For example, although the bankbook P is used as an example of the magnetic recording medium in the above-described embodiment, the present invention can be applied to other media such as a card having the magnetic stripe 23.

  It can be used for a passbook printing mechanism or a passbook issuing machine configured inside an automatic transaction machine such as an automatic teller machine.
