Description

  The present invention relates to a card-like medium transport mechanism. More specifically, the present invention relates to a card-like medium transport mechanism having a head such as a print head.

  As a device for issuing a card-like medium such as a ticket by cutting a roll paper into a predetermined length, for example, there is a ticket issuing device disclosed in Japanese Patent Laid-Open No. 10-21430. This ticket issuing apparatus is shown in FIG. The roll paper 501 is fed out by the conveying means 502, cut into a predetermined length by the cutter unit 503, ticket information such as station name information is printed on the cut ticket 504 by the printing unit 505, and station name information and money amount information are printed by the magnetic head 506. After the magnetic data is written, it is discharged from the issuing port 507. In addition, a reading magnetic head 509 that reads magnetic information of issued tickets inserted from the insertion port 508 is provided.

  The ticket conveyance path branches downstream of the reading magnetic head 509 into a conveyance path leading to the issuing port 507 and a conveyance path leading to the insertion port 508. Further, between this branch point and the reading magnetic head 509, a conveyance path leading to a waste ticket punch 510 that takes in a ticket to be discarded and performs a punching process is branched.

  In this ticket issuing apparatus, magnetic heads 506 and 509 and a waste ticket punch 510 are arranged on the downstream side of the printing unit 505 in the ticket issuing direction. For this reason, the issued ticket inserted from the insertion port 508 and the waste ticket conveyed to the waste ticket punch 510 do not go backward toward the printing unit 505 upstream. In other words, since it is possible for the printing unit 505 to transport the ticket in the reverse direction to cause jamming, the printing unit 505 does not transport the ticket in the reverse direction.

  As another type of ticket issuing apparatus, there is an apparatus that shares an issue port and an insertion port and issues a new ticket and takes in issued tickets using the same port. In such a ticket issuing apparatus, in addition to the main conveyance path passing through the printing section and the like necessary for issuing a new ticket, a bypass conveyance path that bypasses the printing section and the like of the main path is provided so that the printing section does not convey the ticket in the reverse direction. I have to. When the roll paper is cut and a new ticket is issued, the new ticket is transported using the main passage, printed and magnetic data processed, and then issued from the common port. On the other hand, issued tickets taken from the common port initially enter the main conveyance path, but are sent to a detour conveyance path that branches in the middle, bypass the printing unit, return to the main conveyance path, and return to the collection unit Be transported.

In a ticket issuing apparatus that issues a card-like medium by cutting roll paper such as these to a predetermined length, the cut card-like medium may be curled due to being wound on the roll paper. is there. For this reason, guides are provided on both sides of the conveyance path to prevent the tip of the curled card-like medium from being caught by a member provided in the middle of the conveyance path.
JP-A-10-21430

  However, it is difficult to provide a guide for preventing the curled card-like medium from being caught at the position of the print head provided in the middle of the conveyance path. In other words, the print head is wider than the transport roller and magnetic head provided in the middle of the transport path, and the guides can be installed on both sides of the transport roller and magnetic head, but the guides are installed on both sides of the print head. There is no space to install. For this reason, the guide is interrupted at the position of the print head, and the card-like medium may be caught at this portion.

  This problem is also a problem with a structure in which a ticket passes only in one direction with respect to the printing unit 505 as in the above-described ticket issuing apparatus, or a ticket issuing apparatus that employs an end face type as a print head. This is a significant problem in a ticket issuing apparatus in which the card-like medium passes through the print head from both directions and a ticket issuing apparatus that employs a flat type as the print head.

  Further, in the ticket issuing apparatus described in the above-mentioned JP-A-10-21430, the issue port 507 and the insertion port 508 are provided separately, and the conveyance paths leading to each are provided separately, so that the structure becomes complicated. At the same time, the number of parts increases and the apparatus becomes larger. Further, even in the ticket issuing apparatus provided with the detour conveyance path in addition to the main conveyance path described above, similarly, the structure is complicated due to the large number of conveyance paths, the number of parts is increased, and the apparatus is enlarged. There is.

  An object of the present invention is to provide a card-like medium transport mechanism that can prevent catching at the head position even when the card-like medium is curled. It is another object of the present invention to provide a card-shaped medium transport mechanism that can transport a card-shaped medium in any of the reciprocating directions at the head position.

In order to achieve this object, the present invention provides a card-like medium transport mechanism that transports while pressing the head against a card-like medium transported on a transport path, and the head moves so as to enter and retract in the transport path. When the head is in the retracted state, a guide portion is provided that moves along the card-like medium conveyance direction to form a conveyance path, and the guide portions are located upstream and downstream in the card-like medium conveyance direction with the head interposed therebetween. It is provided with two movable guides that are opened and closed by moving in opposite directions along the conveyance path, and the opposite ends of the movable guides are formed with irregularities that are staggered, and when the movable guide is closed , When protrusions viewed from the width direction of the card media enters the recess of the mating and overlapping opposite ends of the movable guide, the movable guide arrangement between the fixed guides arranged at opposite sides of the conveying path Those which are.

Therefore, when the head is not used, the head is retracted from the conveyance path. Then, when the guide portion is moved to the position where the head is, the gap around the head is closed. The card-like medium is guided by the guide portion and passes through this position. On the other hand, when the head is used, the head can enter the transport path by returning the guide portion to the original position. Further, the card-like medium can be transported in any of the reciprocating directions at the head position.
In the card-like medium transport mechanism of the present invention , the movable guide is disposed between fixed guides disposed on both sides of the transport path.

  In the card-like medium transport mechanism of the present invention, the head moves so as to be able to enter and retract in the transport path, and when the head is in the retracted state, the guide section moves along the card-shaped medium transport direction to form the transport path. Therefore, the gap at the position where the head is located can be closed by moving the guide portion. For this reason, when using a card-like medium that is not deformed, even if the card-like medium is curled or curved, the card-like medium is smoothly transported without being caught at the head position. can do. Further, the card-like medium can be transported in any of the reciprocating directions at the head position. For this reason, it is not necessary to provide each card conveyance path for each conveyance direction, the structure is simplified, the number of dimension points can be reduced, and the mechanism can be reduced in size and weight.

  Hereinafter, the configuration of the present invention will be described in detail based on the best mode shown in the drawings. In this embodiment, the card-like medium is described by taking a roll paper as an example. However, the card-like medium is not limited to the card-like medium from which the roll paper is cut, and may be a card-like medium having a card shape from the beginning. The card-like medium is not limited to a paper card, and may be a card-like medium made of plastic, metal, or other material.

The card-like medium carrying mechanism 201 conveys the card-like medium 3 conveyed on the conveying path 202 while pressing the head 129, and the head 129 moves into the conveying path 202 so as to enter and retreat, When the head 129 is in the retracted state (the state shown in FIG. 1), a guide unit 203 is provided that moves along the transport direction (the direction of arrow A in FIG. 1) of the card-like medium 3 and forms the transport path 202. In the present embodiment, a card-like medium transport mechanism 201 employed in a card issuing machine 1 that issues a card-like medium (hereinafter referred to as a card) 3 such as a ticket will be described as an example. However, it is needless to say that the card issuing machine 1 is not limited to a ticket issuing machine. Further, as the head 129, for example, a print head 129 that performs printing on the card 3 is employed. However, the print head 129 is not limited, and other heads may be used.

  The card issuing machine 1 is used for issuing a card 3 such as a ticket, and cuts a roll paper 2 having a printing surface on the front side and a magnetic surface on the back side into a predetermined length, and transfers magnetic data to the magnetic surface. In addition to recording, the card 3 is issued by thermally printing characters on the printing surface. FIG. 33 shows the card 3. Marks 257 are attached to one side of the surface of the roll paper 2 at predetermined intervals, and the card issuing machine 1 determines the length of the roll paper 2 based on the marks 257 and cuts the card into a predetermined length to cut the card. 3. Note that an area denoted by reference numeral 258 in FIG. 33 is an area where data is written and used as a magnetic stripe on the magnetic surface on the back surface. In addition, a hole indicating entry when a card 3 is used is formed at a position indicated by reference numeral 259, and a hole indicating entry is formed at a position indicated by reference numeral 260.

  The card issuing machine 1 includes a roll paper attachment mechanism 4 that holds the roll paper 2, a first take-in mechanism 5 that takes in and transports the roll paper 2 held by the attachment mechanism 4, and the roll paper 2 that is being conveyed. A loop mechanism 6 that forms the slack of the sheet, a second take-in mechanism 7 that takes in and transports the roll paper 2 from the loop mechanism 6, a cut mechanism 8 that cuts the roll paper 2 into a card 3, and a card 3 A card standby unit 9 for standby, a card feeding mechanism 10 for transporting the card 3 while changing its direction at right angles, a write lead unit 11 for recording and reproducing magnetic data on the magnetic surface of the card 3, and a printing surface of the card 3 A printing unit 12 for performing printing, a card issuing unit 13 for carrying out a completed card 3 to the outside, and collecting and storing the card 3 when there is an abnormality in recording and reproduction of magnetic data on the card 3 With the collection unit 14 It is provided.

  As shown in FIGS. 4 to 6, each part of the card issuing machine 1 is accommodated in a thin rectangular parallelepiped casing 15. A main body chassis 210 is fixed in the casing 15. The main body chassis 210 includes a frame guide 211 for attaching the guide portion 203 to the main body chassis 210, and the first take-in mechanism 5, the loop mechanism 6, the second take-in mechanism 7, and the cut mechanism between the main body chassis 210. 8, a frame plate (not shown) for attaching the card standby unit 9, the card feeding mechanism 10, and the write lead unit 11 is attached. The first take-in mechanism 5, the loop mechanism 6, the second take-in mechanism 7, the cut mechanism 8, the card standby unit 9, the card feed mechanism 10, the write lead unit 11, the print unit 12, and the card issue unit 13 are the roll paper 2. They are arranged in order along the transport path. Further, the collection unit 14 is disposed continuously to the card feeding mechanism 10.

  As shown in FIG. 1, the conveyance path 202 includes a vertical first linear conveyance path 159 from the cutting mechanism 8 to the card feeding mechanism 10 and a horizontal second line from the card feeding mechanism 10 to the printing unit 12. It comprises a straight conveyance path 160 and a bent portion 98 positioned between the first straight conveyance path 159 and the second straight conveyance path 160. The bent portion 98 has an arc shape and changes the direction of the first straight conveyance path 159 and the second straight conveyance path 160 to 90 degrees. Thereby, size reduction of the card issuing machine 1 can be achieved. Further, the first straight conveyance path 159 includes a first guide 28 and a second guide 29 facing each other. The second straight conveyance path 160 includes a second guide 29 and a third guide 30 that face each other. The bent portion 98 includes a second guide 29, a first guide 28, and a third guide 30. In the present embodiment, the bent portion 98 changes the direction of the card 3 to 90 degrees, but is not limited to this, and other bending angles can be set according to the arrangement of the conveyance path 202 in the card issuing machine 1. .

  As shown in FIGS. 3 and 4, the casing 15 is provided with a guide door 246. The guide door 246 is attached by hinges 19 and 19 so as to be opened and closed. A spacer plate 248 is fixed to the inner side surface of the guide door 246.

  When the guide door 246 is closed, one side in the width direction of the conveyance path 202 is restricted by the inner side surface of the guide door 246 or the spacer plate 248, and the other side in the width direction of the conveyance path 202 is controlled by the main body chassis. Regulated by 210. Then, the card 3 is conveyed with the main body chassis 210 as a reference plane. A cover plate 32 as shown in FIG. 3 is attached to the upper side of the guide door 246.

  As shown in FIGS. 7 and 11, the roll paper 2 mounting mechanism 4 rotates a rotatable spindle 34 on which a roll core 33, which is a central hole of the rolled paper 2, is fitted, and rotates the spindle 34. A fixed shaft 35 that supports the roll paper 2 and a roll paper attachment member 36 that fixes the roll paper 2 to the spindle 34 are provided. The roll paper mounting member 36 includes a pressing portion 37 positioned on the side of the roll core 33 and a held portion 38 that is inserted and held in the fixed shaft 35. Here, the roll paper 2 is rotatably supported by fitting the roll core 33 to the spindle 34. In FIG. 7, reference numeral 262 denotes a side frame fixed to the main body chassis 210.

  The fixed shaft 35 includes an elastically biased locking portion 39 that locks the inserted held portion 38. The fixed shaft 35 has a substantially cylindrical shape. In detail, the base end surface of the fixed shaft 35 is fixed to a roll paper chassis 247 described later by screwing. A spindle 34 is rotatably fitted on the outer periphery of the fixed shaft 35. A C-ring 41 is fitted to the distal end portion of the fixed shaft 35 to prevent the spindle 34 from falling off the fixed shaft 35.

  The locking portion 39 includes two through holes 42, 42 positioned on one diameter line formed in the vicinity of the center portion of the fixed shaft 35 and, for example, a steel ball slidably accommodated in each through hole 42. And a spring 44 made of a leaf spring screwed to the outside of each through-hole 42. The spring 44 is screwed to the D-cut surface of the fixed shaft 35 so that the free end closes the outside of each through hole 42. Here, since the ball 43 is used, the held portion 38 can smoothly rotate with respect to the fixed shaft 35. In addition, since a steel ball is used as the ball 43, the life of the rotation can be extended.

  In the present embodiment, the two through holes 42 are arranged on a straight line, but the present invention is not limited thereto, and may be arranged at an appropriate angle such as 90 degrees. In this embodiment, two sets of the through hole 42, the ball 43, and the spring 44 are provided. However, the present invention is not limited to this, and one set or three or more sets may be provided. Further, in the present embodiment, the spring 44 is a leaf spring, but is not limited thereto, and for example, as shown in FIG. 12, a compression coil spring that presses the ball 43 toward the center of the fixed shaft 35 can be used. In this case, a contact plate 154 that holds the outer peripheral side of the spring 44 is attached to the D-cut surface of the fixed shaft 35. In the present embodiment, the ball 43 is a steel ball. However, the present invention is not limited to this. For example, the ball 43 may be a plastic ball or another material. In this case, it is possible to change the feeling of moderation and operation when attaching / detaching the held portion 38. That is, when a steel ball is used for the ball 43 as in the present embodiment, a hard and hard feeling can be obtained, whereas when a plastic ball is used for the ball 43, a soft operation feeling can be obtained.

  A flange portion 34 a that protrudes to the outer peripheral side is formed at an end portion of the spindle 34 on the frame side. The roll core 33 fitted to the spindle 34 is fixed in contact with the flange portion 34a. Here, the length of the surface of the flange 34 a of the spindle 34 with which the roll core 33 abuts and the front end surface of the spindle 34 are slightly shorter than the width of the roll core 33. Therefore, the pressing portion 37 of the roll paper mounting member 36 attached to the fixed shaft 35 abuts on the roll core 33 and creates a slight gap with respect to the spindle 34. Thereby, the press part 37 can press the roll core 33 against the flange 34a without a gap.

  The held portion 38 is a central axis that is inserted into the central hole 35 a of the fixed shaft 35. The tip of the held portion 38 in the insertion direction is conical. The held portion 38 is formed with an engaging recess 45 into which the balls 43 and 43 as the locking portions 39 are fitted and locked. The engaging recess 45 is formed in an annular shape near the distal end in the insertion direction of the held portion 38. Further, the step on the leading end side in the insertion direction of the engaging recess 45 is a pressing surface 45a inclined on the outer peripheral side toward the leading end.

  Further, the pressing portion 37 is a disk whose outer diameter is slightly larger than the inner diameter of the roll core 33 of the roll paper 2. In the present embodiment, the holding portion 37 is a disk whose outer diameter is slightly larger than the inner diameter of the roll core 33, but is not limited to this, for example, a disk larger than the entire outer diameter of the roll paper 2, or FIG. As shown in FIG. 4, a cross-shaped plate having two arms longer than the outer diameter of the roll paper 2 can be obtained. In these cases, when the roll paper 2 wound in a cylindrical shape is misaligned with the center and the outer periphery of the rolled paper 2 being axially displaced or in a cylindrical shape, Since the roll paper 2 can be rotated while being pressed by the pressing portion 37, the roll paper 2 can be stably supplied.

  A knob 46 is screwed to the end surface of the held portion 38 opposite to the insertion direction with the pressing portion 37 interposed therebetween. Here, the formation position of the engaging recess 45 in the held portion 38 is such that the balls 43 and 43 are engaged when the held portion 38 is inserted into the fixed shaft 35 and the pressing portion 37 contacts the roll core 33. The pressing surface 45a of the recess 45 is a position to be pressed. In the present embodiment, the held portion 38, the pressing portion 37, and the knob 46 of the roll paper mounting member 36 are separate members, but the present invention is not limited to this, and the whole may be integrally formed.

  When the held portion 38 is inserted into the center hole 35 a of the fixed shaft 35, the tip end portion of the held portion 38 moves the balls 43, 43 against the springs 44, 44 to the outer peripheral side. Then, the held portion 38 is inserted until the pressing portion 37 contacts the roll core 33. Thereby, the balls 43 and 43 are pressed toward the center by the springs 44 and 44 and are fitted into the engaging recesses 45. Here, the ball 43 abuts against the pressing surface 45 a of the engaging recess 45. Since the pressing surface 45a has the outer peripheral side inclined toward the insertion direction, the held portion 38 is urged toward the insertion direction. Therefore, it is possible to prevent the roll core 33 from rattling after the roll paper mounting member 36 is mounted on the fixed shaft 35.

  Further, the loaded roll paper 2 is rotated with respect to the fixed shaft 35 integrally with the spindle 34 and the roll paper attachment member 36. Further, when the knob 46 is pulled, the pressing surface 45 a of the engaging recess 45 moves the balls 43, 43 against the springs 44, 44. Then, the held portion 38 can be extracted from the fixed shaft 35.

  Then, the roll paper 2 taken out from the roll paper attachment mechanism 4 is drawn into the first take-in mechanism 5. The first take-in mechanism 5 includes a first take-in roller 47, a first drive motor composed of a DC motor that rotates the first take-in roller 47, and a tension that presses the roll paper 2 against the first take-in roller 47. And a roller 49. The first take-in roller 47 is rotatably supported by a frame plate (not shown) and the main body chassis 210. The tension roller 49 is rotatably supported by the holder 51. The holder 51 is swingably supported by the frame plate and the main body chassis 210. Further, the holder 51 urges the tension roller 49 against the first take-in roller 47 by a spring (not shown).

  The loop mechanism 6 includes a loop roller 53 and a loop lever 54 that rotatably supports the loop roller 53. The base end portion of the loop lever 54 is rotatably supported by the frame plate and the main body chassis 210. This support position is such that the loop lever 54 extends over the shortest path (indicated by a one-dot chain line L in FIG. 1) of the roll paper 2 between the first take-in roller 47 and the second take-in roller 55. Further, an arc-shaped slide hole 57 is formed in the main body chassis 210 facing the loop lever 54 as shown in FIG. The slide hole 57 is formed at a position where the loop lever 54 can rotate within a range in which the loop lever 54 is inclined approximately 45 degrees downward from a substantially horizontal state.

  Further, a loop sensor (not shown) for detecting the presence of the loop lever 54 is attached to the bottom of the slide hole 57 on the back side of the main body chassis 210. For this reason, when the loop lever 54 is in the lowest position, the loop lever 54 is detected by the loop sensor. Further, when the loop lever 54 is rotated upward, the loop lever 54 is detached from the loop sensor and is not detected.

  Thereby, when the roll paper 2 forms a sufficiently long loop 59 between the first take-in mechanism 5 and the second take-in mechanism 7, the loop roller 53 pushes down the roll paper 2 with its own weight. Since the loop lever 54 is in the lowest position, the loop lever 54 is detected by the loop sensor. When the loop length of the roll paper 2 is short between the first take-in mechanism 5 and the second take-in mechanism 7, the roll paper 2 pushes up the loop roller 53 and the loop lever 54 rotates upward. Therefore, the loop lever 54 is not detected by the loop sensor. The non-detection of the loop sensor activates the first take-in mechanism 5 to make the loop 59 of the roll paper 2 sufficiently long. According to the loop mechanism 6, the loop lever 54 straddles the shortest path between the first take-in roller 47 and the second take-in roller 55. It is possible to prevent the route from being short-cut.

  The second take-in mechanism 7 includes a second take-up roller 55, a second drive motor (not shown) including a stepping motor that rotates the second take-in roller 55, and a roll on the second take-in roller 55. A tension roller 61 that presses the paper 2 is provided. The second take-in roller 55 is rotatably supported by the frame plate and the main body chassis 210.

  A mark detection sensor 21 is disposed between the second take-in roller 55 and the cutting mechanism 8. The mark detection sensor 21 detects the mark 259 formed on the roll paper 2 to convey the roll paper 2 to the cutting mechanism 8 by the length of one card.

  As shown in FIG. 14, the cutting mechanism 8 includes a rotary cutter 68 and a cutter drive motor (not shown). The rotary cutter 68 includes a fixed blade 71 fixed to the bracket 70, a rotary blade 72 provided in parallel with the fixed blade 71 so as to be rotatable, and a cutter arm 73 fixed to one end of the rotary blade 72. is doing. The rotary blade 72 is chamfered on a part of a cylinder to have a D-shaped cross section. Then, the roll paper 2 is passed between the chamfered surface 72 a of the rotary blade 72 and one side edge of the fixed blade 71, and the roll paper 2 is cut by the shearing force between the rotary blade 72 and the fixed blade 71. . A longitudinal groove 73 a is formed in the cutter arm 73. A cam roller (not shown) on a cam ring (not shown) rotated by a cutter drive motor is placed in the groove 73a. For this reason, when the cam ring is rotated by the rotation of the cutter driving motor, the cam roller performs a circular motion, and the rotary blade 72 rotates through the cutter arm 73 to cut the roll paper 2. Then, the roll paper 2 becomes a card 3 by being cut.

  The card standby unit 9 holds and waits for the card 3 until a command to convey the card 3 is issued from the host. The card standby unit 9 includes a standby conveyance roller 78 and a standby tension roller 79. The standby conveying roller 78 and the standby tension roller 79 are rotatably supported by the frame plate and the main body chassis 210. The standby conveyance roller 78 is rotated by a conveyance motor (not shown) composed of a DC motor.

  The card 3 cut by the cutting mechanism 8 is a standby conveying roller 78 and a standby tension roller 79, driving rollers 99 and 100 and a pad roller 97, a recording unit conveying roller 125 and a recording unit tension roller 126, a reproducing unit conveying roller 115 and a reproducing unit. The section tension roller 127 transports the transport path 202 in the order of the first straight transport path 159 → the bending 98 → the second straight transport path 160, and is transported to the printing unit 12.

  The bent portion 98 is provided with a card feeding mechanism 10. The card feeding mechanism 10 is configured to allow the bendable card 3 to travel to the second straight conveyance path 160 from the first straight conveyance path 159 through a bent portion 98 having a predetermined angle. The card feeding mechanism 10 is disposed on the inner side of the first driving roller 99 and the second driving roller 100 disposed on the outer side of the bent portion 98, and on the inner side of the bent portion 98, and simultaneously on the first driving roller 99 and the second driving roller 100. A common roller 97 capable of contacting is provided.

  The first drive roller 99 protrudes from the opening of the first guide 28 to the conveyance path 202. The second drive roller 100 protrudes from the opening of the third guide 30 into the conveyance path 202. The common roller 97 is a tension roller that protrudes from the opening of the second guide 29 into the conveyance path 202 and presses the first drive roller 99 and the second drive roller 100. The diameter of the common roller 97 is small enough to prevent adverse effects such as curling of the card 3 when the card 3 is transported through the bent portion 98 and being caught by the printing portion 12 or the like. For this reason, size reduction of the card feed mechanism 10 can be achieved.

  The first drive roller 99 and the second drive roller 100 are rotated by the transport motor described above.

  Incidentally, the downstream end of the first guide 28 is located between the first drive roller 99 and the second drive roller 100. The second guide 29 is bent at right angles in a circular arc along the common roller 97 and continues to the printing unit 12. Further, the third guide 30 continues from the collection unit 14 to the printing unit 12 through the second drive roller 100.

  Here, a selector 117 is provided between the collection unit 14 and the downstream end of the first guide 28. The selector 117 is a flat plate spring as shown in FIG. 15, and the end on the collection unit 14 side, that is, the upper end 117 a is bent downward at a right angle and is screwed to the reject stacker 121. The opposite end of the selector 117, that is, the lower end 117 b is slightly bent upward at the downstream end of the first guide 28 and is positioned on the card transport surface of the second guide 29.

  The selector 117 is usually positioned below with spring pressure and closes the conveyance path 202. When the card 3 is conveyed in the forward direction, the lower end portion 117b of the selector 117 is pushed up and passes through the bent portion 98. When the card 3 is conveyed in the reverse direction from the write read unit 11, the card 3 is guided upward by the lower end portion 117 b of the selector 117 and is not taken into the first drive roller 99 and the common roller 97. 14 is conveyed.

  Further, a reject conveying roller 118 and a tension roller 119 that presses the card 3 against the reject conveying roller 118 are arranged facing each other in the conveying path 202 near the upper end portion 117a of the selector 117. The reject conveyance roller 118 is rotatably supported by the frame plate and the main body chassis 210. The reject conveying roller 118 is connected to the first driving roller 99 by a gear. Therefore, for example, when the card 3 is transported in the reverse direction (left direction) in FIG. 1, the corner transport rollers 99 and 100 are rotated in the clockwise direction, so that the reject transport roller 118 is rotated in the counterclockwise direction. The card 3 is conveyed to the collection unit 14. Further, the tension roller 119 is rotatably supported by a holder (not shown). This holder is rotatably supported by the frame plate and the main body chassis 210. Further, the holder urges the tension roller 119 against the reject conveying roller 118 by a spring (not shown).

  Here, the positional relationship between the upper end portion of the selector 117 and the reject conveying roller 118 and the tension roller 119 is such that, as shown in FIG. 16, the center of gravity W of the portion ahead of the upper end portion of the selector 117 of the card 3 just before discharge is a power point. When the upper end of the selector 117 is a fulcrum and the reaction force R to the tension roller 119 is an action point, the ratio m: n of the distance m between the force point and the fulcrum and the distance n between the fulcrum and the action point is about 4 .5: 1. By setting this ratio, the front end side of the card 3 becomes sufficiently heavy immediately before being ejected and the rear end of the card 3 is flipped up by the rotation of the tension roller 119. Dropped downward. For this reason, it can be prevented that the leading edge of the card 3 jumps up due to the ejection and is caught on the upper portion of the reject stacker 121 and is again drawn into the transport path 202 by the reject transport roller 118 and the tension roller 119.

  As shown in FIGS. 16 and 17, the collection unit 14 includes a reject stacker 121 and a regulation guide 122. The reject stacker 121 includes a side plate portion 121a located below the upper end portion of the selector 117, and a bottom plate portion 121b located from the lower end of the side plate portion 121a to the side portion of the casing 15. The bottom plate 121b is inclined with the side of the casing 15 facing downward.

  The restriction guide 122 is provided on the extension line of the selector 117, that is, on the upper side along the card 3 ejection direction. For this reason, as shown in FIG. 17, even when the card 3 is curved upward by the curl when being ejected by the reject conveying roller 118, the curving of the card 3 is corrected downward by the regulation guide 122. For this reason, it is possible to prevent the discharged card 3 from being stalled and caught on the upper portion of the reject stacker 121 and drawn into the transport path 202 again. Moreover, since the discharged cards 3 are stacked in order, it is possible to easily manage defective cards and the like.

  The card 3 normally conveyed from the card feeding mechanism 10 is guided to the conveyance path 202 including the second guide 29 and the third guide 30 and conveyed to the write lead unit 11. The write read unit 11 includes a recording head 123 for recording predetermined magnetic data on the card 3 and a reproducing head 124 that is arranged on the downstream side of the recording head 123 and reads the magnetic data recorded on the card 3. I have. The head surfaces of the heads 123 and 124 protrude from the opening of the second guide 29 to the conveyance path 202 and are in pressure contact with a backup roller (not shown). The backup roller protrudes from the opening of the third guide 30 to the conveyance path 202.

  Further, a recording unit conveying roller 125 is provided coaxially with the backup roller of the recording head 123. A reproducing unit conveying roller 115 is provided coaxially with the backup roller of the reproducing head 124. These transport rollers 125 and 115 protrude into the transport path 202 from the opening of the third guide 30.

  Further, a recording unit tension roller 126 is provided at a position facing the recording unit conveyance roller 125 across the conveyance path 202, that is, a position overlapping the recording head 123 in the width direction of the card 3 to press the recording unit conveyance roller 125. ing. Further, a reproduction unit tension roller 127 is provided at a position facing the reproduction unit conveyance roller 115 with the conveyance path 202 interposed therebetween, that is, a position overlapping the reproduction head 124 in the width direction of the card 3, and presses the reproduction unit conveyance roller 115. ing. These tension rollers 126 and 127 protrude from the opening of the second guide 29 into the conveyance path 202.

  The recording unit conveyance roller 125 and the reproduction unit conveyance roller 115 are rotatably supported by the frame plate and the main body chassis 210. The recording unit conveying roller 125 and the reproducing unit conveying roller 115 are rotated by a motor (not shown) together with the second driving roller 100 of the card feeding mechanism 10.

  The recording unit tension roller 126 and the reproducing unit tension roller 127 are rotatably supported by holders (not shown). Each holder is rotatably supported by the frame plate and the main body chassis 210. Further, each holder urges each tension roller 126, 127 to each conveying roller 125, 115 by a spring (not shown).

  A print timing sensor (not shown) is disposed between the write lead unit 11 and the print unit 12. The timing for printing on the thermal surface of the card 3 is achieved by this print timing sensor.

  The printing unit 12 includes a print head 129. The print head 129 is a thermal head, for example. The print head 129 is moved between the retracted position shown in FIG. 1 and the print position (entrance position) shown in FIG. 2 by the drive mechanism shown in FIG. In this embodiment, as the print head 129, a planar print head used in a state where it is inclined with respect to the conveyance path 202 is used. However, a flat type print head used in a horizontal state with respect to the conveyance path 202 may be used, and furthermore, an end face type print head may be used.

  As shown in detail in FIGS. 18 to 31, the guide unit 203 includes two front and rear guide units 205 and 206 disposed with the thermal head 129 and the platen roller 204 interposed therebetween, and driving means for driving the guide units 205 and 206. 207. Each of the guide units 205 and 206 includes two upper fixed guides 208 disposed on both sides of the conveyance path 202 and a movable guide 209 disposed between the upper fixed guides 208.

  The upper fixed guide 208 of each guide unit 205, 206 is fixed to the main body chassis 210 or the frame guide 211. The upper fixing guide 208 is disposed with a predetermined gap between the upper fixing guide 208 and the lower fixing guide 212 fixed to the main body chassis 210 or the frame guide 211. It is a conveyance path 202. The lower fixed guide 212 is provided on the front and rear (the upstream side and the downstream side in the card 3 conveyance direction) with the platen roller 204 interposed therebetween.

  The movable guide 209 of the front side (upstream in the transport direction) guide unit 205 is supported by one fixed guide shaft 213 so as to be slidable from the position shown in FIG. 18 to the rear side, and on the rear side (downstream in the transport direction). The movable guide 209 of the guide unit 206 is supported by two fixed guide shafts 213 so as to be slidable from the position shown in FIG. Although there is one fixed guide shaft 213 for supporting the movable guide 209 of the front guide unit 205, the movable guide 209 is connected to the slide lever 214 of the driving means 207, so that the movable guide 209 is fixed guide. There is no swinging around the shaft 213. Side plates 209a are provided on both sides of the movable guide 209, and each side plate 209a is provided with an elongated slot 215 that is elongated in the card 3 transport direction. The movable guide 209 is supported so as to be slidable in the transport direction A by passing the fixed guide shaft 213 through the long holes 215. Guide spacers 216 are fitted at both ends of each fixed guide shaft 213 so that the center of the upper fixed guide 208 on both sides is not biased to either side with respect to the upper fixed guide 208 on both sides of the movable guide 209. The movable guide 209 is positioned at the position.

  The opposite ends of the movable guides 209 of the front and rear guide units 205 and 206 are formed with irregularities that are staggered. In the present embodiment, two concave portions 217 are provided at the rear end of the movable guide 209 of the front guide unit 205, and two convex portions 218 are provided at the tip of the movable guide 209 of the rear guide unit 206.

  The movable guide 209 of the front guide unit 205 is provided with a long hole 209d for causing the pad roller 219 to protrude into the conveyance path 202. The pad lever 220 that rotatably supports the pad roller 219 is disposed so as to overlap the movable guide 209 of the front guide unit 205, and is supported by the fixed guide shaft 213 together with the movable guide 209. A pad spring 221 is provided between the pad lever 220 and the main body chassis 210 in an extended state, and the pad roller 219 is urged by the pad spring 221 in a direction in which the pad roller 219 protrudes into the conveyance path 202. A drive roller 222 is provided below the pad roller 219.

  Since the pad lever 220 is arranged so as to overlap the movable guide 209 in this way, the mechanism can be reduced in size. Further, by supporting the pad lever 220 and the movable guide 209 with a common fixed guide shaft 213, the fulcrum shaft of the pad lever 220 and the guide shaft of the movable guide 209 can be shared, so the mechanism is downsized. can do.

  Further, the movable guide 209 of the rear guide unit 206 is provided with a long hole 209 b for projecting the pad roller 223 into the transport path 202 and a long hole 209 c for projecting the pad roller 224 into the medium transport path 202. The pad lever 225 that rotatably supports the pad roller 223 is disposed so as to overlap the movable guide 209 of the rear guide unit 206, and is supported by the fixed guide shaft 213 together with the movable guide 209. The pad lever 226 that rotatably supports the pad roller 224 is disposed so as to overlap between the pad lever 225 and the movable guide 209, and is supported by the fixed guide shaft 213 together with the movable guide 209. A pad spring 227 is extended between the pad lever 225 and the pad lever 226 and the main body chassis 210, and the pad rollers 223 and 224 are urged by the pad spring 227 in a direction in which the pad rollers 223 and 224 protrude into the conveyance path 202. Has been. Drive rollers 228 and 229 are provided below the pad rollers 223 and 224, respectively.

  As described above, the pad lever 225 and the pad lever 226 are overlapped and arranged so as to overlap the movable guide 209, so that the mechanism can be miniaturized. Further, by supporting the pad lever 225 and the movable guide 209 by a common fixed guide shaft 213, the fulcrum shaft of the pad lever 225 and the guide shaft of the movable guide 209 can be shared, and the pad lever 226 and the movable guide 209 are movable. By supporting the guide 209 with the common fixed guide shaft 213, the fulcrum shaft of the pad lever 226 and the guide shaft of the movable guide 209 can be shared, so that the mechanism can be miniaturized.

  The driving means 207 includes a solenoid 230 fixed to the main body chassis 210, a solenoid lever 232 that is attached to the main body chassis 210 so as to be swingable by the solenoid lever fulcrum shaft 231, and is swung by the solenoid 230. Two slide levers 214 that move in the direction, and two levers 233 that connect the slide lever 214 and the movable guide 209 of the rear guide unit 206 are provided. The two slide levers 214 slide together as a result of their front and rear portions being connected by interlocking shafts 234 and 235. A solenoid lever 232 is connected to the rear interlocking shaft 235. In addition, an arm 236 is integrally formed at the front end of each slide lever 214, and the tip of each arm 236 is connected to the movable guide 209 of the front guide unit 205 by an interlocking shaft 237. The lever 233 is swingably attached to a shaft 238 to which the driving roller 229 is fixed via a lever sleeve 239. One end of the lever 233 is connected to the slide lever 214 via the shaft 262, and the other end is connected to the movable guide 209 of the rear guide unit 206 via the shaft 263. A shaft 264 is attached to the solenoid lever 232, and a coil spring 240 is extended between the shaft 264 and the main body chassis 210.

  When the solenoid 230 is off, the solenoid lever 232 is attracted to the position shown in FIG. 18 by the coil spring 240, and the slide lever 214 moves the movable guide 209 of the front guide unit 205 to the front side. The lever 233 moves the movable guide 209 of the rear guide unit 206 to the rear side. That is, the front and rear movable guides 209 are open.

  When the solenoid 230 is turned on from this state, the solenoid 230 swings the solenoid lever 232 against the urging force of the coil spring 240 as shown in FIG. For this reason, the slide lever 214 slides rearward, and the movable guide 209 of the front guide unit 205 is slid rearward. Further, the lever 233 is swung by the slide of the slide lever 214, and the movable guide 209 of the rear guide unit 206 is moved to the front side. For this reason, the front and rear movable guides 209 are closed. In the closed state, the convex portion 218 of the movable guide 209 of the rear guide unit 206 enters the concave portion 217 of the movable guide 209 of the front guide unit 205, and the end portion of each movable guide 209 when viewed from the width direction of the card 3. It has a structure that overlaps. For this reason, the card | curd 3 can pass smoothly between any movable guide 209 units 205 and 206 in any direction of a reciprocating direction.

  When the solenoid 230 is turned off from this state, the solenoid lever 232 returns to the original position shown in FIG. 18 and the slide lever 214 is returned to the front position, so that the front and rear movable guides 209 are opened.

  Since the solenoid 230 is used to open and close the movable guide 209, the movable guide 209 can be opened and closed quickly.

  The host of the card issuing machine 1 turns off the solenoid 230 when the card issuing machine 1 is in a waiting state waiting for a customer. For this reason, the movable guide 209 is in an open state. When the card issuing machine 1 is operated by the customer, that is, when the card issuing machine 1 is activated, the host turns on the solenoid 230 to close the movable guide 209.

  While the card issuing machine 1 is operating, the host closes the front and rear movable guides 209 when the thermal head 129 is retracted, and causes the thermal head 129 to enter the medium conveyance path 202 in order to print on the card. Only when the front and rear movable guides 209 are opened.

  A structure for moving the print head 129 is shown in FIG. The print head 129 is fixed to a head support lever 351 attached to the main body chassis 210 so as to be swingable about a shaft 354. An arm 352 is attached to the head support lever 351, and a coil spring 353 is extended between the arm 352 and the main body chassis 210. Accordingly, the print head 129 is always urged by the coil spring 353 in the direction to enter the transport path 202. A head drive motor (not shown) is attached to the main body chassis 210, and the head support lever 251 is raised and lowered by rotating a cam attached to the rotation shaft of the head drive motor.

  The head driving motor is operated by the host. When the head drive motor is rotated by the operation of the host, the cam attached to the rotation shaft of the head drive motor is rotated, and the head support lever 351 is lifted against the urging force of the coil spring 353 to raise the print head 129. When the print head 129 is raised to the retracted position, the host stops the head driving motor.

  In this state, the urging force of the coil spring 353 acts in the direction in which the head support lever 351 is lowered, but the cam does not rotate even when this force acts on the cam. For this reason, unless the head driving motor rotates the cam, the head support lever 351 is not lowered. That is, when the head drive motor is stopped, the print head 129 is held at the retracted position.

  On the other hand, when the head drive motor is rotated by the operation of the host, the force that lifts the head support lever 351 by rotating the cam is released. Therefore, the head support lever 251 is lowered by the urging force of the coil spring 353, and the print head 129 enters the conveyance path 202.

  In the vicinity of the print head 129, guide rollers 252 and 253 for guiding the ink ribbon 251 and guide pins 254 are provided. The ink ribbon 251 wound around the supply-side reel 255 passes between the guide roller 252 and the pad roller 219, passes between the print head 129 and the conveyance path 202, and passes between the guide pin 254 and the guide roller 253. It is taken up by a take-up reel 256. The take-up reel 256 is driven by a motor (not shown). By winding the ink ribbon 251 wound around the supply-side reel 255 by the take-up reel 256, new portions of the ink ribbon 251 are successively supplied to the print head 129.

  The printed card 3 is issued from the issue port 261.

  The operation of the card issuing machine 1 will be described. First, the roll paper 2 is loaded as shown in FIGS. This loading is performed by fitting the roll core 33 of the roll paper 2 to the spindle 34 and attaching the roll paper attachment member 36 to the fixed shaft 35. Then, with the guide door 246 opened, the outer peripheral end of the roll paper 2 is attached to the cutting mechanism 8 through the first take-in mechanism 5, the loop mechanism 6, and the second take-in mechanism 7.

  Then, the guide door 246 is closed and a feed switch (not shown) is pushed to rotate the take-in rollers 47 and 55 and the transport motor. Here, the card is conveyed while being cut sequentially into the number of cards corresponding to the outermost circumference of the roll paper 2 and taken into the collecting unit 14 to be invalidated. This is because the outer peripheral surface of the roll paper 2 is a magnetic surface, so that malfunctions due to scratches and dirt on the magnetic surface are avoided. The take-in to the collection unit 14 is performed by rotating the transport motor forward so that the card 3 is positioned between the second guide 29 and the third guide 30, and then rotating the transport motor to rotate the selector 117 and the reject transport roller 118. After that.

  When the reject operation ends, the first first card 3 enters a standby state. As a result, the set is completed. In this state, the solenoid 230 is off and the movable guide 209 of the guide unit 203 is open.

  When the card issuance command signal is output by the host, the transport motor is rotated. As a result, the card 3 in the card standby unit 9 is conveyed from the first straight conveyance path 159 to the bending 98 to the second straight conveyance path 160. At the same time, the solenoid is turned on, and the movable guide 209 of the opened guide unit 203 is closed.

  In this card 3, magnetic data is written by the recording head 123 and magnetic data is read by the reproducing head 124. Here, if the data reading is normal, the card 3 is conveyed to the position of the print head 129 of the printing unit 12. In this state, since the movable guide 209 is closed, even if the card 3 is curled or curved, the leading edge of the card 3 is removed from the conveyance path 202 and enters the gap on the near side of the print head 129. Can be prevented.

  At this time, when the card 3 is detected by a print timing sensor (not shown), the host turns off the solenoid 230, so that the movable guide 209 is opened. At the same time, the host operates the head drive motor to cause the print head 129 to enter the transport path 202. Thereby, printing is performed on the card 3. Then, the printed card 3 is discharged from the card issuing slot 261. The host operates the head drive motor to retract the print head 129 from the card transport path, and closes the movable guide by turning on the solenoid.

  If there is an abnormality in the reading of magnetic data due to scratches or dust on the card 3, the transport motor reverses when the error is detected, and the card 3 is sent to the collection unit 14 via the selector 117. As a result, the card 3 in which an abnormality has occurred is taken into the reject stacker 121.

  On the other hand, the issue of the next card is started by rotating the second take-in roller 55 when the rear end of the preceding card reaches the vicinity of the recording head 123. For this reason, the roll paper 2 for creating the next card 3 is sent from the cutting mechanism 8 to the card standby unit 9. The roll paper 2 is cut into a card 3 having a predetermined length by the same operation as described above, and waits in the card standby unit 9.

  Here, when the loop 59 is shortened by the rotation of the second take-in roller 55, the loop mechanism 6 is activated and the first take-in roller 47 is rotated. Thereby, the loop 59 can always be secured to a predetermined length.

  In addition, when taking in the card 3 that has been issued once, the host rotates the drive rollers 229 and 228, the platen roller 204, and the drive roller 222 in reverse when an unillustrated EJS sensor detects the card 3 inserted into the issue port 261. Then, the printing unit 12 is reversed and conveyed to the write lead unit 11, and the conveyance motor is further reversed to feed the card 3 to the collection unit 14 via the selector 117. At this time, the movable guide 209 of the guide unit 203 is closed, and even if the card 3 is curved or curled, it does not enter the gap around the print head 129, and the card 3 is prevented from jamming and smoothly conveyed. In addition, the tip of the card 3 can be prevented from being damaged or broken.

  As described above, the card-like medium transport mechanism 201 can smoothly transport the card 3 since the gap of the printing unit 12 can be closed by the movable guide 209 except during printing on the card 3 during operation. And jam can be prevented. In particular, if a flat type is used as the print head 129, jamming is likely to occur. However, the card-like medium transport mechanism 201 can reliably prevent jam even if the flat type print head 129 is used. Further, when the flat type print head 129 is employed, printing can be performed quickly, so that the card 3 can be issued quickly. Furthermore, since the printing unit 12 can reciprocate the card 3 in the reciprocating direction, there is no need to separately provide a conveyance path for issuing the card 3 and a conveyance path for taking in the card once issued. It becomes simple, the number of parts can be reduced, the manufacturing cost can be reduced, and the mechanism can be reduced in size and weight.

  On the other hand, according to the attachment mechanism 4 of the roll paper 2 of the present embodiment, the held portion 38 of the roll paper attachment member 36 is elastically urged and locked to the locking portion 39 of the fixed shaft 35. Since the fastening by the screw member is not required for the locking, the roll paper 2 can be held without being loosened or rattling with respect to the spindle 34 regardless of the rotation direction of the roll paper 2 and the spindle 34. it can. For this reason, the roll paper 2 can be supplied stably.

  Further, according to the attachment mechanism 4 of the roll paper 2, the held portion 38 is elastically urged and locked by the locking portion 39, and the locking is tightened by a screw member. Since it is not necessary, the roll paper attachment member 36 can be removed from the spindle 34 by pulling the held portion 38 from the fixed shaft 35 with a force larger than the urging force. In this state, the roll paper 2 can be attached to and detached from the spindle 34. For this reason, the roll paper replacement operation can be quickly performed with one touch, and workability can be improved.

  Further, since the held portion 38 is elastically biased and locked to the locking portion 39, when the held portion 38 rotates with respect to the fixed shaft 35, the locking portion 39 makes a long period of time. Of stable friction. For this reason, when the pulling of the roll paper 2 is stopped, the roll paper 2 is stopped by the friction between the held portion 38 and the locking portion 39. As a result, it is possible to reduce the occurrence of slack between the roll paper 2 and the first take-in mechanism 5 due to the continued rotation due to the inertia of the roll paper 2, so that the next time the first take-in mechanism 5 is operated. When the roll paper 2 is pulled from the slack state, the slack disappears and the tension rapidly increases. For this reason, slip of the roll paper 2 can be prevented and stable conveyance can be maintained.

  As described above, the card-like medium transport mechanism 201 is a roller configured by, for example, the first take-in roller 47, the tension roller 49, the second take-in roller 55, and the tension roller 61 arranged in the transport path 202 for the roll paper 2. The roll paper 2 pulled out by the means 241 and conveyed by the roller means 241 is cut into a predetermined length to form a card 3, and the card 3 is conveyed. The storage unit 242 in which the roll paper 2 is stored protrudes outward from the reference surface 243 of the transport path 202 of the card 3 and has a width W2 larger than the width of the roll paper 2 as shown in FIG. The conveying path 202 that conveys the card 3 is provided with a regulating means 244 that regulates the width direction of the card 3 conveyed to a position upstream of the cutting mechanism 8.

  In the storage unit 242, a window 245 having a slightly larger diameter than the roll paper 2 is provided in the main body chassis 210, and the window 245 is closed by a roll paper chassis (magnetic roll paper mounting plate) 247. With this structure, the width W <b> 2 of the storage portion 242 is increased by the thickness of the main body chassis 210.

  Here, the main body chassis 210 is a member that determines the position on the far side in the width direction of the transport path 202, and the inner side surface of the main body chassis 210 is a reference surface 243 of the transport path 202. The storage unit 242 that stores the roll paper 2 is generally formed with reference to the reference surface 243. That is, conventionally, the storage unit 242 is configured by the main body chassis 210 that is the reference surface 243 of the conveyance path 202 and the guide door 246. In this structure, a space that can absorb the turbulence of the roll paper 2 can be provided on the front side of the storage unit 242 (on the roll paper attachment unit 36 side), but on the back side of the storage unit 242 (on the main body chassis 210 side). Cannot provide a space for absorbing the turbulence of the roll paper 2.

  In contrast, in this embodiment, the reference surface 243 of the transport path 202 is the main body chassis 210, but the width W <b> 2 of the storage unit 242 is determined by the roll paper chassis 247 and the guide door 246 outside the main body chassis 210. ing. For this reason, the width W2 of the storage portion 242 can be widened to the back side. That is, the space S1 that can absorb the turbulence of the roll paper 2 can be provided on the front side of the storage unit 242, and the space S2 that can absorb the turbulence of the roll paper 2 also on the back side of the storage unit 242. Can be provided. Therefore, even if the roll paper 2 is turbulent, the roll paper 2 can be smoothly rotated. Further, it is possible to prevent contact between the roll paper 2 and the members constituting the storage unit 242 (in this embodiment, the roll paper chassis 247, and in the conventional configuration, the main body chassis). It is possible to prevent crushing. For example, the width of the storage portion 242 is increased by 0.6 mm.

  The restricting means 244 is provided on the inner surface of the guide door 246. In the present embodiment, the restricting means 244 is a convex portion that guides and positions the roll paper 2 so as not to be displaced in the width direction. In the present embodiment, one restricting means 244 is provided in the vicinity of the first take-in mechanism 5 on the transport path of the roll paper 2, and two restricting means 244 is provided in the vicinity of the second take-in mechanism 7. Yes. By providing the restricting means 244, the roll paper 2 can be positioned in the width direction even if the width W2 of the storage portion 242 is larger than the width W1 of the transport path 202 in the cut mechanism 8, the write lead portion 11, and the printing portion 12. It can supply to the cutting mechanism 8 in the performed state.

  The collection unit 14 that collects the conveyed card-like medium 3 and the conveyance path 202 in the vicinity of the collection unit 14 are formed with a width W3 that is larger than the width of the card 3.
