Description

  The present invention relates to an apparatus for reading and writing magnetic information by a magnetic head that records, reproduces and conveys a magnetic information medium and faces the outer periphery of the drum. More specifically, the present invention relates to an improvement in the structure of a magnetic information medium recording / reproducing apparatus that uses a magnetic information medium along the outer periphery of a drum.

  One of the flexible magnetic information media has a long card length and data read (read) / write (write) like a boarding pass of a passenger aircraft made of paper magnetic cards. Various data such as departure and destination are recorded as magnetic information in the boarding pass, and this data is read by a magnetic card reader installed at the entrance gate of the airport. Written.

  Some magnetic card readers for processing such magnetic information media are configured by a magnetic information medium recording / reproducing apparatus as described below. That is, for example, an apparatus including a rotatable drum, a conveying unit disposed so as to face the outer periphery of the drum, a magnetic head disposed so as to face the outer periphery of the drum, and the like. It is conveyed along the outer periphery, and during that time, magnetic information is read by a magnetic head or magnetic information is newly written (see, for example, Patent Document 1 and Patent Document 2). For example, a flat belt is used as the conveying means.

Japanese Patent No. 2810600 Utility Model Registration No. 2549807

  However, when the magnetic information medium is sandwiched between the outer periphery of the drum and the conveying means (for example, a flat belt) as described above, the magnetic information medium is made of paper. It is difficult to cut with high accuracy, and the dimensions of the magnetic information medium may expand and contract due to moisture, so that the magnetic information medium does not always approach the magnetic head and the magnetic track of the magnetic information medium does not always pass through a predetermined position. For this reason, the track position accuracy may not be sufficient when performing a magnetic information reading or writing operation.

  In addition, when it is difficult to keep the positional relationship between the drum position and the magnetic head constant, it may be possible to press the side surface of the magnetic information medium using a pressing member or the like so as to always pass the predetermined position. Since the magnetic information medium is made of paper, there is a problem that it is difficult to transport the magnetic head to a certain position with respect to the magnetic head because the paper is bent or the side edge of the medium is crushed by a strong pressing force. For this reason, the output at the time of writing or reading of magnetic information may be unstable.

  Therefore, the present invention provides a magnetic information medium recording / reproducing system that improves the track position accuracy and stabilizes the output during reading or writing when magnetic information is read or written while conveying a flexible magnetic information medium along the outer periphery of the drum. An object is to provide an apparatus.

  To achieve this object, the invention according to claim 1 is directed to a rotatable drum whose outer periphery forms a medium conveyance path for the magnetic information medium, and a magnetic information medium disposed opposite to the outer periphery of the drum. In a magnetic information medium recording / reproducing apparatus having a conveying means for conveying along the magnetic recording medium, and a magnetic head disposed at a position facing the magnetic recording portion of the magnetic information medium, the edges of the magnetic information medium in the conveying direction are in contact with each other A medium conveyance reference surface is provided at one side of the medium conveyance path and serves as a reference position of the magnetic recording portion of the magnetic information medium with respect to the magnetic head, and the distance between the drum and the conveyance means in the vicinity of the magnetic head is The drum is inclined relative to the devices other than the drum in the opening direction or the direction in which the pressure between them decreases.

  In this magnetic information medium recording / reproducing apparatus, since the rotating drum is inclined relative to the equipment other than the drum, the distance between the drum and the conveying means is wide (or the magnitude of pressure). Is biased. Moreover, in the case of the present invention, the drum-carrying means is inclined so that the distance between the drum and the conveying means becomes wide (or the pressure decreases) in the vicinity of the magnetic head. For this reason, the magnetic information medium conveyed while being sandwiched between the drum and the conveying means is subjected to the action of a lateral force due to the wide / narrow difference (or pressure difference), and as a result is close to the magnetic head side. Be transported. Since the medium transport reference surface is installed on the magnetic head side, the magnetic information medium is eventually transported in the magnetic information medium recording / reproducing apparatus with the side edge of the medium facing the medium transport reference surface. Will be.

  Further, when the magnetic information medium is separated from the vicinity of the magnetic head, the action of the lateral force due to the wide and narrow gap (or pressure difference) between the drum and the conveying means is reduced, and on the diameter side of the drum relative to the magnetic head. This acts in the opposite direction to the vicinity of the magnetic head. For this reason, when the magnetic information medium is transported along the outer periphery of the drum, the magnetic information medium is alternately separated and approached in the medium width direction with respect to the medium transport reference surface. It is also possible to prevent damage to the magnetic information medium due to excessive shift.

  In such a magnetic information medium recording / reproducing apparatus, it is preferable that the magnetic head is inclined at the same angle as the drum and parallel to the drum. For example, when the magnetic information medium is a paper medium and the drum has an inclination angle of about 1 °, the magnetic information can be recorded and reproduced by a non-tilted magnetic head. If the magnetic head is tilted and level with the drum as described, information recording and reproduction can be performed more reliably.

  According to a third aspect of the present invention, in the magnetic information medium recording / reproducing apparatus according to the first or second aspect, another magnetic head is provided at a point-symmetrical position of the magnetic head with the center position of the drum as the center of symmetry. It is.

  According to the magnetic information medium recording / reproducing apparatus of claim 1, in the vicinity of the magnetic head, the magnetic information medium is conveyed while the side edge of the magnetic information medium is in contact with the medium conveyance reference surface. The track position accuracy when reading or writing the magnetic information is further increased, and as a result, the output becomes more stable.

  According to the magnetic information medium recording / reproducing apparatus of the second aspect, since the magnetic head is inclined to be horizontal with the drum, the contact between the magnetic recording unit and the magnetic head is stabilized, so that information recording and reproduction can be performed more reliably. Can be performed.

  According to the magnetic information medium recording / reproducing apparatus of claim 3, even when the magnetic information medium is taken in the apparatus in the reverse direction, the magnetic information medium is provided with both sides of the magnetic information medium. Even in this case, it is possible to accurately read or write new information on the magnetic information of the magnetic information medium conveyed near the frame on the other magnetic head.

  Hereinafter, the configuration of the present invention will be described in detail based on embodiments shown in the drawings.

  1 to 8 show an embodiment of the present invention. A magnetic information medium recording / reproducing apparatus 1 according to the present invention includes a rotatable drum 4, a conveying unit 5 that conveys the magnetic information medium along the outer periphery of the drum 4, a drive unit 6 that drives the conveying unit 5, And a magnetic head 7 for reading or writing magnetic information. The drum 4 and the magnetic head 7 are inclined in the direction in which the distance between the drum 4 and the conveying means 5 in the vicinity of the magnetic head 7 is increased, or in the direction in which the pressure therebetween decreases.

  In this magnetic information medium recording / reproducing apparatus 1, an annular medium conveyance path in which a conveyance means 5 composed of a flat belt is arranged around a drum 4 and travels with the magnetic recording medium sandwiched between the drum 4 and the conveyance means 5. 3 is formed. Further, the information on the magnetic information medium is read / written / verified during rotation with respect to the magnetic recording medium moving around the drum 4 by the recording / reproducing magnetic head 7 which is a recording / reproducing means arranged in the middle of the medium conveyance path 3. A series of information processing such as is continuously processed.

  Further, in the present embodiment, the operation of the flappers 24 and 25 arranged in the middle of the medium conveyance path 3 changes the conveyance direction of the magnetic information medium according to the recording information defect of the magnetic information medium or the necessity of information writing. Switching is performed as appropriate, and a predetermined magnetic treatment is performed, or the discharge port 30 is sent to the next process.

  Note that the drum 4 whose outer periphery serves as the medium conveyance path 3 of the magnetic information medium is not directly driven by the drive unit (for example, drive motor) 6 itself, but friction with the conveyance means 5 disposed around the drum 4. It has a structure that can be rotated by.

  The drum 4 is a rotatable rotating body whose outer periphery forms a medium transport path 3 for a magnetic information medium. For example, in this embodiment, main frames 11 and 12 are formed on both sides of a space where the drum 4 is installed and the medium transport path 3 is formed, and the drum 4 is installed between the main frames 11 and 12. . The main frames 11 and 12 are connected by a rod serving as a spacer, and face each other in parallel at a predetermined interval. The distance between the frames 11 and 12 is slightly wider than the width of the magnetic information medium, and is provided so that a slight clearance is generated when the magnetic information medium is conveyed. In the present embodiment, the main frame 11 is provided at one side of the medium conveyance path 3 so that the edge of the magnetic information medium conveyance direction side portion contacts. That is, the inner side surface of the main frame 11 includes a medium conveyance reference surface 8 that serves as a reference position of the magnetic recording unit of the magnetic information medium with respect to the magnetic head 7.

  The drum 4 is preferably a resin molded product such as polyacetal. That is, it is desirable to use a material having a low friction coefficient in order to slide the magnetic information medium laterally toward the medium conveyance reference surface 8 of the main frame 11, and a resin molded product is suitable. Moreover, if it has a certain amount of softness | flexibility and flexibility, it is preferable at the point that rotation shake can be prevented by rotating while deform | transforming.

  Further, the drum 4 can be rotated in both the forward and reverse directions, and rotates in either direction according to the rotation direction of the drive unit 6 capable of rotating in the normal and reverse directions. In FIG. 2, the rotation direction of the drum 4 is represented as CW in the clockwise direction in FIG. 2 and CCW in the counterclockwise direction (see FIG. 2).

  In addition, although it is possible to use the drum 4 having a solid shape, that is, a non-hollow shape, in the present embodiment, the hollow drum 4 is selected from the viewpoint of weight reduction of the drum 4 and switching speed when the drum 4 is reversed. Adopted. Since the hollow drum 4 is lighter in weight than the solid drum 4, the inertia (inertia) can be reduced, which is advantageous in terms of downsizing the magnetic information medium recording / reproducing apparatus 1 and switching speed when the drum 4 is reversed. is there.

  Furthermore, in the present embodiment, a plurality of (for example, three in this embodiment) inner support rollers 13 to 15 that support the drum 4 from the inside are disposed in the hollow interior of the drum 4 (see FIGS. 2 and 3). ). For example, in the present embodiment, the inner support rollers 13 to 15 are arranged so as to be evenly spaced approximately every 120 °, and each is rotatably attached to the support shaft 52 (see FIGS. 2 and 3).

One of these inner support rollers 13 is provided in the vicinity of the magnetic head 7 and is attached to the main frame 12 so as to be rotatable by a support arm 34. The support arm 34 is biased toward the outer peripheral side by a biasing means (not shown) such as a coil spring, and as a result, the inner support roller 13 is constantly biased toward the outer peripheral side where the magnetic head 7 is located.

  In addition, an outer roller 16 constituting a part of the conveying means 5 is provided at a position facing the drum 4 (that is, on the outer peripheral side opposite to the inner support roller 13 across the drum 4). The drum 4 is clamped from inside and outside together with the inner support roller 13 (see FIGS. 2, 3, and 8).

  On the other hand, the support shafts 52 that support the remaining inner support rollers 14 and 15 are preferably fixed so as not to move. As a result, the drum 4 is clamped at only one point (for example, in the vicinity of the magnetic head 7 in the case of the present embodiment) where the rotational shake is to be suppressed, and the support is free and the movement is not restricted at other points. Make up structure.

  Here, the inner support roller 13 and the outer roller 16 as well as the magnetic head 7 and its pad roller 26 are preferably arranged side by side on the same line in the direction orthogonal to the conveyance direction of the magnetic information medium. Even if it is slightly back and forth, the effect of suppressing the rotational shake can be made so as not to affect the position of the magnetic head 7.

  In addition, as described above, the embodiment in which the inner support rollers 13 to 15 are equally arranged at three places has been described here, but this is only an example, and for example, four or more places can be arranged.

  The drum 4 of this embodiment has a hollow cylindrical shape, and an annular convex rib 4a is provided on the inner periphery of the cylinder, and the cross-sectional shape thereof is a channel shape (see FIG. 5). ). An annular convex portion 4b projecting inward is provided at the center of the convex rib 4a, and an annular groove portion 13a into which the convex portion 4b is fitted is formed at the center of the outer peripheral surface of the center of the inner support roller 13. (See FIG. 5).

  The inner support roller 13 also functions as a guide that prevents the drum 4 from moving and shaking in the axial direction while holding the drum 4 from the inside in a rotatable state. The inner support rollers 13 to 15 including the inner support roller 13 are rotatably supported by a support shaft 52 fixed to a flange portion formed at the edge of the circular hole of the main frames 11 and 12. Has been. The support shaft 52 is inclined at a predetermined angle by inclining the flange portion according to the inclination of the drum 4. Therefore, in this embodiment, the drum 4 and the inner support rollers 13, 14, and 15 are arranged in parallel. That is, the drum 4 is inclined and arranged by the inclination of the inner support roller 13.

  The transport means 5 is disposed opposite to the outer periphery of the drum 4 in order to transport the magnetic information medium along the outer periphery of the drum 4. Specifically, for example, a flat belt, a roller, or a combination of these can be used as the conveying means 5 that can send out a magnetic information medium along at least a part of the outer periphery of the drum 4.

  Here, the specific configuration of the conveying means 5 in this embodiment will be described. As shown in FIG. 2 and the like, three rubber-circulating belts (indicated by reference numerals 5a, 5b, and 5c in FIGS. 2 and 3). Are arranged so as not to overlap the periphery of the drum 4 (see FIGS. 2 and 3).

  Each belt 5a, 5b, 5c is provided so as to be pressed against the outer periphery of the drum 4 while being stretched by two or three of the pulleys 17-23. As shown in FIG. 2 and FIG. 3, the belts 5a, 5b, 5c of this embodiment are arranged apart from each other, and between the belt 5a and the belt 5c and between the belt 5b and the belt 5c, respectively, Flappers 24 and 25 for changing the transport direction are provided.

  Each of the belts 5a, 5b, and 5c described above is a set of two, and is arranged symmetrically in the width direction (axial direction) of the drum 4 (see FIG. 5).

  As shown in FIG. 5, each belt 5a, 5b, 5c is disposed so as to contact a portion of the outer peripheral surface of the drum 4 where there is no convex rib 4a (see FIG. 5). Further, the pulleys 17 to 23, the outer roller 16 and the like have the left and right equal shapes so that the pair of left and right belts 5a, 5b and 5c can be fed out equally (see FIG. 5).

  In the case of the present embodiment, the length of the outer periphery of the drum 4 is longer than the length (vertical length) of the magnetic information medium in the feed direction, so that the drum 4 is always connected to one of the belts 5a, 5b, 5c. The belts 5a, 5b, and 5c are in contact with each other and receive a rotational force.

  Further, at least one of the pulleys 17 to 23 and the outer roller 16 that spans the belts 5a, 5b, and 5c is dynamically connected so that the driving force from the driving unit 6 is transmitted. Yes. For example, in the case of the present embodiment, the power transmission belt 31 is stretched around the output shaft of the drive unit 6, the pulley 67, the pulley 68, the pulley 69, and the idler 32, and the power of the drive unit 6 is supplied to the pulleys 17, 19, 22. Via the belt 5a, 5b, 5c (see FIG. 6).

  The drive unit 6 is a drive source that drives the transport unit 5, and, for example, in the case of this embodiment, is configured by a stepping motor that can rotate forward and backward (hereinafter also referred to as the drive motor 6).

  The arrangement of the drive motor 6 is not particularly limited to any position. However, in the present embodiment, the drive motor 6 is arranged inside the drum 4 having a hollow structure as described above to effectively use the space. I am trying.

  The driving force by the driving motor 6 is transmitted to the pulleys described above to operate the belts 5a, 5b, 5c. The drive motor 6 is provided so that a magnetic information medium is detected by a sensor (not shown) disposed in the medium conveyance path 3 and the like, and the motor rotation speed is appropriately controlled.

  The drive motor 6 is fixed to one main frame, for example, the left main frame 11 in FIG.

  The motor mounting plate 53 is fixed to the main frame 11 in a state of being arranged near the edge of the drum 4 by, for example, a plurality of connecting pins 59.

  A knob 60 for manually rotating the motor shaft is provided on the front side of the drive motor 6. When the drive motor 6 cannot be driven for some reason, the respective conveyor belts 5a, 5b, 5c can be manually rotated. It is like that.

  The magnetic head 7 is a head for reading magnetic information recorded in a magnetic recording portion of a magnetic information medium or writing new magnetic information. The magnetic head 7 of this embodiment is installed in a position facing the outer periphery of the drum 4 at a position facing the magnetic recording portion of the magnetic information medium (see FIGS. 2, 3, and 5).

  Further, a rotatable pad roller 26 is attached to a position facing the magnetic head 7 in contact with the magnetic head 7 (see FIG. 5). The pad roller 26 presses the magnetic recording portion of the magnetic information medium passing between the magnetic head 7 and the pad roller 26 toward the magnetic head 7 so that the magnetic information can be reliably read and written. It has become.

  As shown in FIG. 5, the pad roller 26 and the magnetic head 7 are respectively supported by a gimbal (elastic) on a support frame 61 fixed to the main frame 11. As the support frame 61, for example, a box-shaped frame (with a space provided therein) as shown in FIG. 4 is adopted.

  The medium conveyance reference surface 8 is a surface that serves as a reference position of the magnetic recording portion of the magnetic information medium with respect to the magnetic head 7. It is provided on the inner surface of the frame 11 (the side with the drum 4) (see FIG. 5). When the magnetic information medium is transported in a state where the edge of the magnetic information medium is in contact with the medium transport reference surface 8, the track position accuracy when reading or writing the magnetic information is increased, leading to stable output.

  The medium transport reference surface 8 may be formed by an independent member, but in the case of this embodiment, one of the left and right main frames 11 and 12 that define both sides of the medium transport path 3, preferably The inner surface of the main frame 11 on the side close to the magnetic head 7 is used. When the magnetic information medium is transported in a state where the edge thereof is in sliding contact with the medium transport reference surface 8, the magnetic information section travels at a certain position in the width direction of the medium transport path 3, The track position accuracy when reading or writing is increased, leading to stable output.

  Further, the magnetic information medium recording / reproducing apparatus 1 is provided with intake ports 27 to 29 for taking the magnetic information medium into the apparatus and an outlet 30 for sending it out of the apparatus (see FIGS. 2 and 3). .

  In the case of the magnetic information medium recording / reproducing apparatus 1 of the present embodiment, the magnetic information medium is provided with three inlets, ie, a first inlet 27, a second inlet 28, and a third inlet 29. It can be taken in from the corresponding intake.

  The flappers 24 and 25 are configured as switching means for switching the feeding direction of the magnetic information medium transported through the medium transport path 3. Of these, the flapper 24 is provided between the belt 5b and the belt 5c, and switches the feeding direction of the magnetic information medium conveyed in the CCW direction. That is, the magnetic information medium is sent to the medium conveyance path 3 toward the discharge port 30 if the flapper 24 is moved to the drum 4 side, while the flapper 24 is separated from the rotating drum 4. It is sent to a conveyance path along the outer periphery of the drum 4 (see FIGS. 2 and 3).

  Further, the flapper 25 is provided between the belt 5a and the belt 5c, and the position thereof is changed according to the manner in which the magnetic information medium is conveyed. That is, when the magnetic information medium is taken in from any of the intake ports 27 to 29 and conveyed to the drum 4, the flapper 25 approaches the drum 4 to secure the medium conveyance path 3 for the magnetic information medium, When the taken magnetic information medium is transported around the rotary drum 4, the medium transport path 3 for the magnetic information medium is secured in the same manner away from the drum 4 (FIGS. 2 and 2). 3).

  As for the transport system in the magnetic information medium recording / reproducing apparatus 1, rollers for transporting the magnetic information medium from the respective intake ports 27 to 29 to the outer periphery of the drum 4 or from the outer periphery of the drum 4 to the discharge port 30 are appropriately used. Although these transport systems of the magnetic information medium recording / reproducing apparatus 1 in the present embodiment are not particularly novel parts, a known transport system is sufficient, and detailed description thereof will be given in this specification. Is omitted.

  Reference numeral 45 is a rotatable cover that can open the magnetic head 7 and its peripheral portion, and reference numeral 54 is a rotatable cover that can open a part of the medium transport path 3 (FIGS. 4, 7, etc.). reference).

  Furthermore, in the magnetic information medium recording / reproducing apparatus 1 of this embodiment, the drum 4 and the magnetic head 7 are connected to the main frame 11 from the viewpoint of further improving the track position accuracy when reading or writing magnetic information and stabilizing the output. , 12 and so on. That is, in the direction in which the gap between the drum 4 and the outer roller 16 is increased in the vicinity of the magnetic head 7 or in the direction in which the pressure between them decreases (for example, a counterclockwise direction in FIG. 5 when described with reference to FIG. 5). The drum 4 and the magnetic head 7 are slightly tilted with respect to the main frames 11, 12, etc. (see FIG. 5, etc.).

  Specifically, the drum 4 is inclined with respect to the left and right main frames 11 and 12 that regulate the travel width of the magnetic information medium, on the plane connecting the rotation center of the magnetic head 7 and the drum 4. The magnetic head 7 is also tilted with respect to the main frames 11 and 12 so that the magnetic head 7 contacts the tilted magnetic information medium in parallel.

  The inclination angle in this case is set to 1 ° in the magnetic information medium recording / reproducing apparatus 1 of the present embodiment, for example, but is not limited to a certain value, and the configuration of the apparatus, the type of the magnetic information medium, etc. Various values can be taken according to the above. If the conventional rotating drum 4 is mounted perpendicular to the main frames 11 and 12 and θ = 90 ° in FIG. 5, in the case of the present embodiment in which the inclination angle is 1 ° as described above. Is θ = 91 ° (see FIG. 5).

  Here, the configuration for inclining the drum 4 as described above is not particularly limited, but it is needless to say that the configuration is as simple as possible. For example, in the present embodiment, as described above, the inner support rollers 13 to 15 are arranged so as to be evenly spaced approximately every 120 ° and are rotatably attached to the main frame 12 (see FIGS. 2 and 3). At this time, first, three bracket-like projecting pieces (hereinafter referred to as brackets) 51 projecting inwardly are provided on the main frame 12, and the inner support rollers 13 to 15 are provided on the support shafts 52 supported by the brackets 51. Is attached (see FIGS. 2 and 3). Then, the support shaft 52 and the inner support rollers 13 to 15 are also inclined by slightly bending each of the brackets 51, whereby the rotary drum 4 is also inclined. More specifically, the bracket 51 that supports the inner support roller 13 is slightly bent toward the opposite side of the main frame 11 in FIG. 5 (the front side of the page in FIGS. 2 and 3).

  Further, the bracket 51 that supports the inner support roller 15 is slightly bent toward the side of the main frame 11 in FIG. 5 (in the depth direction of the paper surface in FIGS. 2 and 3), and supports the inner support roller 13. 51 and parallel. Furthermore, the bracket 51 that supports the inner support roller 14 is slightly bent while being twisted, and is parallel to the brackets 51 described above. According to the brackets 51 bent as described above, the drum 4 is tilted at a predetermined angle (in the case of this embodiment) via the support shafts 52 and the inner support rollers 13 to 15 that are inclined by the same angle. 1 °) can be inclined. In addition, a through hole 51a is formed at the base portion of each bracket 51 to facilitate folding when the bracket 51 is slightly bent (see FIGS. 2 and 3). For example, in the present embodiment, these through holes 51a are formed as substantially rectangular holes that are long in the circumferential direction. However, this is an example, and the shape is limited to such a shape as long as the bracket 51 is easily bent. There is nothing.

  Further, in this embodiment, the opposite side of the support shaft 52 is received by the motor mounting plate 53, but a part of the motor mounting plate 53 is also bent as appropriate (see FIG. 6). That is, the portion of the motor mounting plate 53 that receives the upper support shaft 52 (support shaft that supports the inner support roller 13) 52 is the side where the main frame 12 is located in FIG. 5 (the depth direction of the paper in FIG. 5). Folded slightly.

  On the other hand, the portion of the motor mounting plate 53 that receives the lower support shaft (support shaft that supports the inner support rollers 14 and 15) 52 is the side opposite to the main frame 12 in FIG. 5 (in FIG. 5). It is slightly bent toward the front of the paper. After all, since both are bent to the extent that they are parallel to the bracket 51, the mounting operation is simple in that each support shaft 52 can be mounted vertically.

  In this embodiment, the motor mounting plate 53 is provided with an elongated through hole and a folding line (indicated by reference numerals 53a and 53b in FIGS. 3 and 6, respectively) so that a predetermined portion of the motor mounting plate 53 can be easily bent. (See FIG. 5).

  Further, a driving force from a driving unit (for example, a driving motor) 6 is applied to any one of the pulleys 17, 18, 19, 21, 22, and 23 at both ends where the belts 5 a, 5 b, and 5 c are stretched. Are respectively wound around the power transmission belt 31 so as to be transmitted simultaneously. For example, in the case of the present embodiment, the power transmission belt 31 is stretched over the pulley 44 fixed to the motor shaft of the drive motor 6, the pulley 67, the pulley 68, the pulley 69, and the idler 32. Are simultaneously transmitted to the belts 5a, 5b, 5c via the pulleys 17, 19, 22 so as to be rotated synchronously (see FIG. 6).

  Reference numerals 20 and 32 in the figure are idlers (idle pulleys) that prevent the conveyor belt 5b and the power transmission belt 31 from interfering with each other or allow them to be sufficiently wound around the drive pulley 44. .

  Here, the first conveyor belt 5 a is supported by a frame 45 including a pair of plates that can swing around a pivot 47 that penetrates the left and right main frames 11 and 12, and swings around the pivot 47. Thus, the rotary drum 4 can be exposed away from the drum 4. Such a structure can be easily taken out when the magnetic information medium is jammed immediately after being taken in. Pulleys 17, 18 and an outer pulley 16 are rotatably supported by the frame 45, and the pulleys 17, 18, the outer pulley 16 and the conveying belt 5 a stretched around these are integrated together via the frame 45. It moves as one block. This frame 45 is provided with a connecting pin 46 that can slide in the long hole 49, and the connecting pin 46 is hooked on a claw 48 formed on the main frame 12 side so that the frame 45 has a fixed position. Fixed in a relationship. The connecting pin 46 is hooked by a cover 50 that can slide in the same direction. The cover 50 is provided so as to be detached from the claw 48 by sliding.

  In the present embodiment, the magnetic head 7 and the rotating drum 4 are arranged side by side between the left and right main frames 11 and 12. That is, the width between the left and right main frames 11 and 12 is the width of the medium transport path 3 through which the magnetic information medium passes, and is slightly wider than the width of the magnetic information medium. It is set so that a clear clearance will occur. As described above, the main frames 11 and 12 are connected to each other with a rod serving as a spacer interposed therebetween, so that the main frames 11 and 12 face each other at a predetermined interval. On the inner surface of each main frame 11, 12, a magnetic information medium carry-in path frame 35, a discard path frame 42 and a discharge path frame 43 are fixed by screws or the like, and both side edges of the magnetic information medium are fixed. It is provided so as to support and form a conveyance path. In the space between the carry-in path frame 35, that is, the central space between the main frames 11, 12, the first to third take-in rollers 36a, 36b, 37a for sandwiching and transporting the magnetic information medium are used. , 37b, 38a, 38b are respectively arranged. These rollers 36 a, 36 b, 37 a, 37 b, 38 a, 38 b are driven by a belt 62 branched from the drive motor 6. Further, another take-in roller 39 is provided behind these rollers.

  Further, the magnetic information medium recording / reproducing apparatus 1 includes first to third intake ports 27 to 29 for taking the magnetic information medium into the device, a discharge port 30 for sending it out of the device, and a waste port 41, respectively. The frame 35, the waste path frame 42 and the discharge path frame 43 are formed. In the case of the present embodiment, there are provided three inlets of the first inlet 27, the second inlet 28, and the third inlet 29, and magnetic information media of different types and categories are respectively provided from the corresponding inlets. It is provided so that it can be incorporated. Each of the frames 35, 42 and 43 is composed of a set of two plates arranged with a certain space so as to sandwich both side edges of the magnetic information medium, and screwed to the left and right main frames 11, 12 respectively. It is fixed by.

  Reference numeral 54 in the figure denotes a frame that supports an optical scanner 56 that optically reads a magnetic information medium immediately before being taken into the medium conveyance path 3, and can swing around a pivot 55 that penetrates the main frames 11 and 12. As a result, the carry-in route can be opened. Further, the optical scanner 56 is configured to be swingable about a shaft 62 so as to be opened and closed.

  According to the magnetic information medium recording / reproducing apparatus 1 of this embodiment in which the drum 4 and the magnetic head 7 are inclined as described above, the following operation is given to the magnetic information medium. That is, as a result of inclining the drum 4 slightly with respect to the main frames 11, 12, etc. by inclining a part of the motor mounting plate 53 for supporting the drum 4, the bracket 51, and the support shaft 52, for example, the drum 4 And the outer roller 16 are biased (or there is a pressure difference between them), and the medium conveyance path 3 in the vicinity of the magnetic head 7 is narrower near the main frame 12, and the main The one closer to the frame 11 has a slightly wider shape (see FIG. 5). When the magnetic information medium is conveyed through the medium conveyance path 3 with a bias in the interval or pressure in this way, the lateral force is directed from the narrow side to the wide side (or from the high pressure side to the low side). As a result, the magnetic frame moves toward the main frame 11, and as a result, the side edge of the magnetic information medium is conveyed while being in contact with the medium conveyance reference surface 8. As a result, the track position accuracy when reading or writing the magnetic information on the magnetic information medium is further increased, and the output becomes more stable.

  Further, on the diameter side of the rotary drum 4 with respect to the magnetic head 7, the medium transport path 3 is narrower near the main frame 11 and wider near the main frame 12. The information medium approaches the main frame 12. For this reason, the magnetic information medium is alternately separated from and brought close to the main frames 11 and 12 in the vicinity of the magnetic head 7 and the diameter side of the drum 4 when the magnetic information medium is circulated and conveyed on the conveyance path 3. Therefore, the side edge of the magnetic information medium is not damaged by being too far from the main frame on one side.

  Here, a brief description of the operation of the magnetic information medium recording / reproducing apparatus 1 will be added. First, by operating the drive motor 6, the power transmission belt 31, the pulleys 67, 68, 69, and the pulleys 17 are operated. , 19 and 22 rotate the belts 5a, 5b and 5c, respectively. Further, the drum 4 that is in contact with the belts 5a, 5b, and 5c also rotates with this. Here, the magnetic information medium taken into the apparatus through the inlets 27 to 29 rotates and moves together with the drum 4 while being sandwiched between the drum 4 and the belts 5a, 5b, 5c. The magnetic information medium thus transported passes under the magnetic head 7 in the meantime, and at this time, the magnetic information is written in the magnetic recording unit. When this magnetic information writing is completed, the driving unit 6 once stops rotating and rotates in the reverse direction to rotate the drum 4 in the CCW direction (see FIGS. 2 and 3). When the magnetic information medium transported in the CCW direction passes through the magnetic head 7 again, this time, magnetic information verify read (read operation for information confirmation) is performed. At this time, the flapper 24 is switched to a position away from the drum 4 and guides the magnetic information medium conveyed in the CCW direction to the discharge port 30.

  In addition, as a specific application example of the magnetic information medium recording / reproducing apparatus 1 that performs such an operation, for example, any one of a plurality of magnetic information media connected by perforations is folded in a bellows shape. A case where the processing is performed by taking in from the intakes 27 to 29 will be described.

  First, when it is detected by a sensor (not shown) that the magnetic information medium has been inserted (for example, provided in the vicinity of the insertion opening of the roller 39), the drive motor 6 is operated, and the three power transmission belts 31 are used. The drive pulleys 17, 19, 22 of the transport means 5 and the transport belts 5 a, 5 b, 5 c wound around these are rotated. Along with this, the drum 4 in contact with the belts 5a, 5b, 5c rotates. When the magnetic information medium at the front end of the continuous ticket is taken into the medium conveyance path 3 by the conveyance belt 5a, pre-reading is performed, and when information such as a ticket type and a serial number is recorded in advance on the magnetic information medium, the information is read. Is determined. And when it is a genuine magnetic information medium, it is cut off from the perforation by the cutter 33 and taken as a single magnetic ticket. The cutter 33 used here is mounted so as to be able to move linearly, and it is possible to apply a blade almost perpendicularly to the bill (see FIGS. 2 and 3).

  Here, in the case of the magnetic information medium recording / reproducing apparatus 1 of the present embodiment, since the drum 4 is provided in a slightly inclined state, the gap between the horizontally disposed conveyor belt 5a and the drum 4 is set. The frictional force on the magnetic information medium is biased (the frictional force closer to the main frame 12 is larger and the frictional force closer to the main frame 11 is smaller). A skid force that biases the medium conveyance reference surface 8 acts. For this reason, the magnetic information medium sandwiched between the drum 4 and the transport belt 5a passes through the vicinity of the magnetic head 7 with the edge of the side pressed against the medium transport reference surface 8. As a result, when reading or writing the magnetic information on the magnetic information medium, high track position accuracy is realized, and as a result, the output becomes more stable.

  In the magnetic information medium recording / reproducing apparatus 1 of the present embodiment, the outer circumference of the drum 4 is longer than the length of the magnetic information medium (the length in the transport direction). The belt always comes into contact with any one of the conveyor belts 5a, 5b, 5c and receives a rotational force from the belt. Therefore, the drum 4 of this embodiment continues to rotate while being supported by the inner support rollers 13, 14, 15 and the surrounding transport belts 5a, 5b, 5c. At this time, the drum 4 is sandwiched between the pair of rollers 13, 16 from inside and outside. The roller 4 is supported between the rollers 13 and 16 and the remaining fixed inner support rollers 14 and 15 so as to swing around the contact point between the outer peripheral surfaces of the drum 4 and the roundness and rotational vibration of the drum 4 itself. Regardless, there is an advantage that the drum 4 passes through the same place in the vicinity of the point sandwiched between the rollers 13 and 16. In particular, in the case of the drum 4 of the present embodiment configured by a flexible resin molded product, the rotating drum 4 itself is deformed during rotation, so that the inner peripheral surface of the drum 4 is all the inner support rollers 13. , 14 and 15, the rotational vibration of the drum 4 itself can be suppressed. Therefore, the positional relationship between the position of the drum 4 and the magnetic head can be kept constant, and the writing / reading output of magnetic data is stabilized.

  The magnetic ticket / paper magnetic card (magnetic information medium) separated by the cutter 33 as described above is necessary when the outer periphery of the drum 4 rotates once in the CW direction and then passes through the magnetic head 7 again. Information is written. When it is detected by a sensor (not shown) that writing has been completed (the magnetic information medium has reached a predetermined position), the drive motor 6 temporarily stops and then reversely rotates (reversely rotates the drum 4). The information medium is conveyed in the CCW direction, and the magnetic head 7 is again passed in the reverse direction to perform verify read, and the written contents are collated. If there is no problem in the collation result, the flapper 24 is switched and the magnetic information medium is discharged from the discharge port 30 (see FIGS. 2 and 3). If the collation result is inconvenient, the discard flapper 40 is switched without switching the flapper 24, and the drum 4 is rotated as it is and discarded from the discard path 41.

  The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the scope of the present invention. For example, in the present embodiment, a case where a flexible magnetic information medium such as an airline ticket is read or written by the magnetic head 7 is described as an example. However, the present invention is not limited to this, and a flexible medium such as a check or a postcard is used. The present invention can also be applied to an apparatus that performs the above inspection. Furthermore, for example, the present invention can be applied to an apparatus provided with an optical scanner or a barcode reader as information reading means. In other words, the present invention can be applied to any device that is configured to pass a magnetic information medium along a reference plane along a certain reference surface, regardless of whether the object is to be read or written, such as magnetism, an image, and a barcode. It can be applied to improve the track position accuracy and stabilize the output.

  Further, in the portion of the outer periphery of the drum 4 that is the opposite of the magnetic head 7 (in the vicinity of the pulleys 20 and 21 in FIGS. 2 and 3), the magnetic information medium being transported is closer to the main frame 12 side. The case where it sticks to the surface of the main frame 12 may occur. In view of such a case, another magnetic head 7 can be provided on the main frame 12 in advance. In such a case, since the pair of magnetic heads are symmetrically arranged across the center position of the drum 4, a device capable of reading and writing information regardless of the direction at the time of taking in the magnetic information medium is configured. can do. That is, when the magnetic information medium is taken into the apparatus in the correct orientation, reading (writing) is performed by the magnetic head 7 while moving along the medium conveyance reference plane 8 as described in the present embodiment. If the magnetic information medium is taken in the opposite direction, the magnetic information medium is read while being conveyed while the edge is in contact with the main frame 12. (Writing) may be performed, and any case can be handled.

  In the present embodiment, the form in which the drum 4 is slightly inclined by inclining a part of the motor mounting plate 53, the bracket 51, and the support shaft 52 has been described. This is a magnetic information medium being conveyed. It is only one aspect for bringing the to the side. That is, as described above, in the magnetic information medium recording / reproducing apparatus 1, the distance between the drum 4 and the conveying means 5 in the vicinity of the magnetic head 7 gradually opens as the medium conveying reference plane 8 is approached (or those Since the magnetic information medium can be moved to the side if it is configured so that the pressure in between decreases gradually as it approaches the medium conveyance reference plane 8, the drum 4 and the conveyance means 5 are eventually obtained. The interval (or pressure) between and may be relatively open (or decreased). Therefore, in the case of a device in which a part of the motor mounting plate 53, the bracket 51, the support shaft 52, and the drum 4 are kept horizontal without being tilted, and other members such as the conveying means 5 are slightly tilted. In addition, the same effect as the apparatus of the present embodiment can be obtained.

  Furthermore, although the embodiment in which the drum 4 and the magnetic head 7 are inclined has been described in the present embodiment, this is also an example of a preferred embodiment of the magnetic information medium recording / reproducing apparatus 1 and is not limited thereto. That is, in the magnetic information medium recording / reproducing apparatus 1 as in the present embodiment, from the viewpoint of more reliably recording and reproducing information, the magnetic head 7 is inclined at the same angle as the drum 4 and parallel to the drum 4. It is most desirable that the inclination angle of the magnetic head 7 with respect to the magnetic magnetic recording portion of the magnetic information medium is 0 (zero). For example, the magnetic information medium is a paper medium and the drum 4 is inclined as in this embodiment. If the angle is about 1 °, the magnetic information is recorded even if the inclination angle of the magnetic head 7 with respect to the magnetic recording unit is not 0 (specifically, about 1 °). It is possible to play or play. In particular, when the pad roller 26 and the magnetic head 7 are supported by the gimbal (elastic) as in the present embodiment, the magnetic head 7 may be opposed to the magnetic information medium at an inclination angle of 0. Therefore, even if the magnetic head 7 is not tilted from the beginning, it is possible to sufficiently perform magnetic recording and reproduction.
