DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll paper mounting mechanism for rotatably supporting a wound roll paper.
More specifically, the present invention relates to a roll paper mounting mechanism suitable for supporting roll paper of a card issuing machine.

[0002]

2. Description of the Related Art In a card issuing machine for issuing cards at a game store such as a pachinko parlor, a roll paper having a thermal surface on a front side and a magnetic surface on a back side is cut into a predetermined length, and magnetic data is written on the magnetic surface. Some cards issue a card by printing a number or the like on the thermal surface while recording.

As shown in FIG. 32, a mounting mechanism 200 for attaching roll paper to a card issuing machine is provided with a fixed shaft 202 vertically screwed to a frame 201 and rotatably fitted to the fixed shaft 202. With roll paper 2
A spindle 205 into which a roll core 204 of 03 is fitted;
Some spindles 205 have an annular fixing screw 206 that is screwed into a screw portion 205a formed on the outer peripheral surface of the end opposite to the frame 201 of the spindle 205. This mounting mechanism 2
00, the fixing screw 206 is tightened to
By pressing the roll core 204 against the flange portion 205b at the outer periphery of the spindle 205 and fixing the roll core 203, the roll paper 203 can be rotatably attached to the fixed shaft 202 integrally with the spindle 205 and the fixing screw 206.

As another roll paper mounting mechanism 200, as shown in FIG. 33, a fixed shaft 202 which is vertically screwed to a frame 201 and in which a roll core 204 of a roll paper 203 is rotatably fitted. And a fixing plate 208 for fixing the roll core 204 to the fixed shaft 202 by screwing to the tip end surface of the fixed shaft 202 to prevent the roll core 204 from falling off the fixed shaft 202. . In this mounting mechanism 200, the roll paper 203 can be rotatably mounted on the fixed shaft 202 by tightening the fixing screw 208 and fixing the holding plate 207 to the fixed shaft 202.

[0005]

However, in the above-described roll paper mounting mechanism 200, the rotating roll core 20 is provided.
Since the fixing screws 206 and 208 are used for fixing the fixing screw 4, for example, when the right screw is used, the fixing screw 2 is used.
When the roll paper 203 is pulled in the left-hand rotation direction and rotated when viewed from the side where 06 and 208 are attached, the tightening is likely to be loosened. To prevent this loosening, the fixing screw 2
Since the tightening direction of the roll paper 203 and the rotation direction of the roll paper 203 need to be the same, the fixing screws 206 and 2 depend on the rotation direction of the roll paper 203 attached to the card issuing machine.
08 must be changed to one with a different tightening direction.

When replacing the roll paper 203,
It is necessary to rotate the fixing screws 206 and 208 to attach and detach the roll paper 203, and the exchange operation becomes complicated using both hands. In addition, when a left-handed screw is used, an uncomfortable operation occurs, and it is difficult to perform a quick replacement operation. Further, when the roll paper 203 suddenly runs out except during maintenance of the card issuing machine, it is difficult to quickly replace the roll paper 203.

Further, in the roll paper mounting mechanism 200 shown in FIG. 32, the contact surface between the fixed shaft 202 and the rotating spindle 205 is a cylindrical surface, and the mounting mechanism 200 shown in FIG.
In this case, since the contact surface between the fixed shaft 202 and the rotating roll core 204 is a cylindrical surface, the frictional resistance during rotation is small in each case. Since the roll paper 203 is a long roll and heavy, the inertia force due to the rotation increases. For this reason, if the roll paper 203 is rotated at the time of issuing a card, the roll paper 203 is rotated by inertia after the issuance of the card and loosened. When the roll paper 203 becomes slack, the slack is conveyed as it is when the next card is issued, but when the slack disappears, the wound roll paper 203 is suddenly pulled. As a result, slipping of the roll paper 203 easily occurs in the transport mechanism, and the transport of the roll paper 203 may not be performed properly.

In view of the above, the present invention can reliably hold the roll paper without loosening regardless of the rotation direction of the roll paper, can replace the roll paper quickly, and reduce the occurrence of slack due to the inertia of the rotation of the roll paper. An object of the present invention is to provide a roll paper mounting mechanism that can be reduced.

[0009]

To achieve the above object, a roll paper mounting mechanism according to a first aspect of the present invention comprises a rotatable roll paper setting spindle into which a center hole of a wound roll paper is fitted. A fixed shaft that rotatably supports the spindle, a center hole of the roll paper is fitted to the spindle, and the roll paper rotatably supports the roll paper so that the outer peripheral end of the wound roll paper can be pulled out. The mounting mechanism includes a roll paper mounting member having a pressing portion located on the side of the periphery of the center hole of the roll paper and a held portion inserted and held in the fixed shaft, and is inserted into the fixed shaft. And a resiliently biased locking portion for locking the roll paper to the spindle while being locked to the held portion.

Therefore, the roll paper is fitted to the spindle and fixed by the roll paper mounting member. Here, the held portion of the roll paper mounting member is elastically urged and locked by the locking portion of the fixed shaft, and the locking does not require tightening of the screw member. Regardless of the rotation direction of the spindle, the roll paper is always held without looseness with respect to the spindle.

Further, the held portion of the roll paper mounting member is elastically urged and locked by the locking portion of the fixed shaft, and this locking does not require tightening of a screw member. Therefore, if the held portion is pulled out from the fixed shaft with a force larger than the urging force, the roll paper mounting member can be removed from the spindle. In this state, the roll paper can be attached to and detached from the spindle. For this reason, the replacement of the roll paper can be performed by pulling out the held portion from the fixed shaft with a force larger than the urging force.

Further, since the held portion of the roll paper mounting member is elastically urged and locked by the locking portion of the fixed shaft, when the held portion rotates with respect to the fixed shaft. Friction is provided by the locking portion. Therefore, when the pulling of the roll paper is stopped, the roll paper stops due to the friction between the held portion and the locking portion. Thereby, it is possible to reduce the occurrence of slack in the roll paper due to the rotation by the inertia of the roll paper.

Further, in the roll paper mounting mechanism according to the second aspect, the held portion has an engaging concave portion into which the locking portion provided on the fixed shaft is fitted and locked, and is formed at the center of the fixed shaft. The center axis is inserted into the center hole. Therefore, since the locking portion is locked in the engaging concave portion having the step in the mounting / removing direction of the held portion, the held portion can be securely fixed.

Further, in the roll paper mounting mechanism according to the third aspect, the pressing portion presses the peripheral edge of the center hole of the roll paper from the side by the elastic urging of the engaging concave portion and the locking portion and fixes the roll paper to the spindle. In such a manner as to apply a biasing force in the direction of the movement. Therefore, the pressing portion presses the peripheral edge of the center hole of the roll paper from the side and fixes the roll paper to the spindle, whereby the roll paper is securely fixed without rattling to the spindle.

Further, in the roll paper mounting mechanism according to the fourth aspect, the locking portion is a plurality of balls urged toward the center of rotation by a spring. Therefore, since the ball is locked to the held portion, the held portion can be smoothly rotated with respect to the fixed shaft, and the held portion can be easily removed. In addition, a light moderation feeling can be obtained by locking the ball and the held portion.

The mounting mechanism 4 for the roll paper 2 is shown in FIGS.
As shown in FIG. 7, a rotatable spindle 34 into which a roll core 33 which is a center hole of the rolled roll paper 2 is fitted.
And a fixed shaft 3 rotatably supporting the spindle 34.
5 and a roll paper mounting member 36 for fixing the roll paper 2 to the spindle 34. Roll paper attachment member 36
Has a holding portion 37 located on the side of the roll core 33 and a held portion 38 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.

The fixed shaft 35 has an elastically urged locking portion 39 for locking the inserted held portion 38.
The fixed shaft 35 has a substantially cylindrical shape. The base end surface of the fixed shaft 35 is fixed to the frame of the casing 15 by screwing. A spindle 34 is rotatably fitted on the outer periphery of the fixed shaft 35. A C-shaped ring 41 is fitted to the distal end of the fixed shaft 35 to prevent the spindle 34 from dropping off the fixed shaft 35.

The locking portion 39 has two through holes 4 formed on one diameter line formed near the center of the fixed shaft 35.
2, 42, a ball 43, 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 covers the outside of each through hole 42. here,
Since the ball 43 is used, the held portion 38 can rotate smoothly with respect to the fixed shaft 35. Further, since a steel ball is used as the ball 43, the life of rotation can be extended.

In the present embodiment, the two through-holes 42 are arranged on a straight line. However, the present invention is not limited to this, and they may be arranged at an appropriate angle such as 90 degrees. Further, 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 to this, and may be a compression coil spring that presses the ball 43 toward the center of the fixed shaft 35 as shown in FIG. 29, for example. In this case, a contact plate 154 for pressing the outer peripheral side of the spring 44 is attached to the D-cut surface of the fixed shaft 35. Further, in the present embodiment, the ball 43 is a steel ball, but is not limited to this. For example, a plastic ball or another material can be used. In this case, a sense of moderation and a sense of operation when attaching and detaching the held portion 38 can be changed. That is, when a steel ball is used for the ball 43 as in the present embodiment, a crisp and firm moderation can be obtained, whereas when a plastic ball is used for the ball 43, a soft operation feeling can be obtained.

At the end of the spindle 34 on the frame side, a flange portion 34a protruding outward is formed. Then, the roll core 33 fitted to the spindle 34 contacts and is fixed to the flange portion 34a. Here, the length of the surface of the flange 34 a of the spindle 34 abutting on the roll core 33 and the distal end surface of the spindle 34 are slightly shorter than the width of the roll core 33. For this reason, the pressing portion 37 of the roll paper mounting member 36 mounted on the fixed shaft 35 comes into contact with the roll core 33 and a slight gap is formed with respect to the spindle 34. As a result, the pressing portion 37 is
Can be pressed against the flange 34a without any gap.

The held portion 38 has a central hole 35 of the fixed shaft 35.
The center axis is inserted into a. The tip of the held portion 38 in the insertion direction has a conical shape. And the held part 3
8 is formed with an engagement recess 45 into which the balls 43, which are the engagement portions 39, are fitted and locked. Engaging recess 45
Is formed in an annular shape near the tip of the held portion 38 in the insertion direction. Further, the step on the distal end side in the insertion direction of the engagement concave portion 45 has a pressing surface 45a whose outer peripheral side is inclined toward the distal end side.

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 outer diameter of the pressing portion 37 is the roll core 33.
The disk is slightly larger than the inner diameter of the roll paper 2, but is not limited thereto. For example, the disk may be larger than the entire outer diameter of the roll paper 2 or may be longer than the outer diameter of the roll paper 2 as shown in FIG. It can be a cross-shaped plate having the arms of a book.
In these cases, when the center and the outer peripheral portion of the wound roll paper 2 are displaced in the axial direction to be conical or the roll paper 2 wound in a cylindrical shape is not aligned and has irregularities on the side surface, Since the side surface of 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 a holding portion 37 interposed therebetween. Here, the formation position of the engagement concave portion 45 in the held portion 38 is determined by inserting the held portion 38 into the fixed shaft 35 and pressing the balls 43, 4 when the pressing portion 37 abuts on the roll core 33.
Reference numeral 3 denotes a position at which the pressing surface 45a of the engaging recess 45 is pressed. In the present embodiment, the held portion 38, the pressing portion 37, and the knob 46 of the roll paper attachment member 36 are separate members, but the invention is not limited to this, and the whole may be integrally formed.

The held portion 38 is inserted into the center hole 35a of the fixed shaft 35.
Is inserted, the tip of the held portion 38 is
3 is moved to the outer peripheral side against the springs 44, 44. Then, the held portion 38 is inserted until the pressing portion 37 comes into contact with the roll core 33. As a result, the balls 43, 43 are pressed toward the center by the springs 44, 44 and fit into the engagement recesses 45. Here, the ball 43 comes into contact with the pressing surface 45 a of the engaging recess 45. Since the pressing surface 45a has its outer peripheral side inclined toward the insertion direction, the held portion 38 is urged in 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.

The mounted roll paper 2 rotates with respect to the fixed shaft 35 integrally with the spindle 34 and the roll paper mounting member 36. Further, when the knob 46 is pulled, the pressing surface 45a of the engaging concave portion 45 moves the balls 43, 43 against the springs 44, 44. And the held part 3
8 can be withdrawn from the fixed shaft 35.

6 so as to be rotatable. This support position is such that the loop lever 54 straddles the shortest path (shown by a dashed line in FIG. 7) of the roll paper 2 between the first take-in roller 47 and the second take-up roller 55. And the loop lever 54
A guide projection 56 is formed on the back side of the. Further, an arc-shaped slide hole 57 is formed in the base plate 16 facing the guide projection 56 as shown in FIGS. 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 downward by about 45 degrees from a substantially horizontal state.

Further, a loop sensor 58 for detecting the presence of the guide projection 56 is attached to the lower side of the slide hole 57 on the back side of the base plate 16. Therefore, when the loop lever 54 is at its lowest position, the guide protrusion 56 is detected by the loop sensor 58. Further, when the loop lever 54 is rotated upward, the guide protrusion 56 is disengaged from the loop sensor 58 and is not detected.

Accordingly, when the roll paper 2 forms a loop 59 having a sufficient length between the first taking-in mechanism 5 and the second taking-in mechanism 7 as shown in FIG. 53
Pushes down the roll paper 2 by its own weight, and the loop lever 54 is lowered to the lowest position. Therefore, the guide protrusion 56 is detected by the loop sensor 58. When the loop length of the roll paper 2 is short between the first capture mechanism 5 and the second capture mechanism 7, the roll paper 2 pushes up the loop roller 53 and the loop lever 54 rotates upward ( (Shown by a two-dot chain line in the figure), so that the guide projection 56 is not detected by the loop sensor 58. By the non-detection of the loop sensor 58, the first take-in mechanism 5 is operated, and the loop 59 of the roll paper 2 is made to have a sufficient length. 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-up roller 55. It is possible to prevent a shortcut from being applied to a route.

In this embodiment, the loop lever 54 is rotatable. However, the present invention is not limited to this, and the loop lever 54 can be slid up and down as shown in FIG. Also in this case, the loop lever 54 'is connected to the roll paper 2 of the first take-in roller 47 and the second take-up roller 55.

The arm 90 is urged by an urging spring 94 composed of a torsion coil spring in a direction in which the standby tension roller 79 advances into the card path. The pin 91 is connected to the iron core 96 of the solenoid 89 via the intermediate lever 95. Therefore, the arm 90 is rotated against the biasing spring 94 by the excitation of the solenoid 89. As a result, the standby tension roller 79 is retracted from the card path.

When the solenoid 89 is excited and the standby tension roller 79 is retracted from the card path, the push plate 77 protrudes into the card path so that the push plate 77 cannot move with the fourth guide 29 sandwiching the card 3 and stands by. Since the conveying roller 78 idles, the card 3 enters a standby state. When the solenoid 89 is demagnetized and the standby tension roller 79 projects into the card path by the urging spring 94, the standby transport roller 78 sandwiches the card 3 together with the standby tension roller 79 and transports the card 3.

On the downstream side of the cut length sensor 22, a corner 98 is formed by bending a card passage at a right angle in order to reduce the size of the card issuing machine 1. This corner 9
8 is provided with a corner transport mechanism 10. As shown in FIGS. 6 and 14 to 16, the corner transport mechanism 10 includes a corner tension roller 97 located inside the corner 98 of the card passage, and a corner tension roller 97 located upstream of the corner 98. The first transport roller 99 which is pressed by the corner and the corner portion 9
8 and a corner second transport roller 100 that is located at a downstream portion of the printer 8 and is pressed by the corner tension roller 97. The corner tension roller 97 is exposed to the card passage from the opening of the fourth guide 29. The corner first transport roller 99 is exposed to the card path from the opening of the third guide 28. Corner second transport roller 100 is the fifth
It is exposed to the card passage from the opening of the guide 30.

Then, the corner tension roller 97
Is rotatably attached to the tip of the tension lever 101. The diameter of the corner tension roller 97 is set small enough to prevent the card 3 from being curled when the card 3 is conveyed through the corner 98 and adversely affecting the card.
For this reason, the size of the corner transport mechanism 10 can be reduced.

As shown in FIG. 16, the tension lever 101 is slidable on a dividing line D that substantially bisects a right angle portion of the corner portion 98. Specifically, the tension lever 101 is installed on the front side of the base plate 16 so as to be slidable in the sliding direction S, and is attached to the tip of the roller shaft 102 for supporting the corner tension roller 97.
A first guide shaft 106 protruding from the rear side of the base plate 16 through the first hole 103 of the base plate 16 and the adjustment slot 105 of the adjustment plate 104, and a second hole 107 of the base plate 16. Second guide shaft 1 protruding from the back side of base plate 16
08 is attached.

The first guide shaft 106 and the roller shaft 102 are located coaxially and screwed with one bolt 109. The first hole 103 is formed to be larger than the diameter of the first guide shaft 106. For this reason, the first guide shaft 106 is
It can be moved in each direction while being inserted into the hole 103. The adjustment slot 105 of the adjustment plate 104 is a slot along the sliding direction S of the tension lever 101 and has a width equal to the diameter of the first guide shaft 106. Therefore, the first
The guide shaft 106 is guided by the adjustment slot 105 and moves in the sliding direction S. Further, the adjusting plate 104 has fastening slots 110, 110 extending in a direction perpendicular to the sliding direction S. Then, fine adjustment of the direction of the tension lever 101 is performed while shifting the tension lever 101 in a direction perpendicular to the sliding direction S, and then the fastening slots 110, 110 are screwed to the back side of the base plate 16. Here, the adjustment plate 10
As shown in FIG. 16, the center position L of the corner tension roller 97 and the corner first transport roller 99 is equal to the center distance L of the corner tension roller 97 and the corner second transport roller 100, as shown in FIG. , A line connecting the center of the corner tension roller 97 and the center of the corner first transport roller 99 around the extension line of the tension lever 101 in the sliding direction S, the center of the corner tension roller 97 and the corner second transport roller 100. The line connecting the center and the line makes an equal angle θ.

As shown in FIG. 15, the second hole 107 is a long hole along the sliding direction S of the tension lever 101 and has a width equal to the diameter of the second guide shaft 108. Therefore, the second guide shaft 108 is guided by the second hole 107 and moves in the sliding direction S. Then, the first guide shaft 106
Is guided by the adjustment elongated hole 105 and the second guide shaft 108 is guided by the second hole 107, so that the tension lever 101 is slid in the sliding direction S.

In this embodiment, the position of the first guide shaft 106 can be adjusted in the direction perpendicular to the sliding direction S by the adjusting plate 104, and the second guide shaft 108 cannot be adjusted in the direction perpendicular to the sliding direction S. However, the present invention is not limited to this, and the second guide shaft 108 is supported by the adjustment plate 104 so as to be adjustable in a direction perpendicular to the sliding direction S, and the first guide shaft 106 is orthogonal to the sliding direction S. It may not be possible to make adjustments in the direction to be performed. In the present embodiment, the position of the first guide shaft 106 is adjustable by the adjustment plate 104. However, the present invention is not limited to the use of the adjustment plate 104. For example, the first guide shaft 10 can be used without using the adjustment plate 104.
6 may be an eccentric shaft rotatable with respect to the tension lever 101, and the sliding direction S of the tension lever 101 may be finely adjusted by rotation of the first guide shaft 106.

Further, between the first guide shaft 106 and the second guide shaft 108 on the back side of the base plate 16,
11 is fixed. An urging spring 112 formed of a tension coil spring is stretched between the spring hook shaft 111 and the second guide shaft 108. Therefore, the tension lever 101 urges the corner tension roller 97 in a direction in which the corner tension roller 97 comes into contact with each of the corner transport rollers 99 and 100.
Here, since the corner conveying rollers 99 and 100 are arranged at the same angle θ with respect to the sliding direction S of the tension lever 101, the urging force from the corner tension roller 97 is applied to the corner conveying rollers 99 and 100. Divided equally. The slot 113 in the figure is for avoiding interference with a portion of the spring hanging shaft 111 slightly projecting to the front side of the base plate 16.

The corner first transport roller 99 is rotatably supported by the fourth side plate 82 and the base plate 16 as shown in FIG. The corner first transport roller 99 is rotated by a transport motor 83 connected to a motor pulley 84, a drive belt 87, a large transport pulley 85, a small transport pulley 86, and a toothed belt 88. Further, the corner second transport roller 100 is rotatably supported by the sixth side plate 114 and the base plate 16. The corner second transport roller 100 is provided with a transport pulley 84
, A driving belt 87, a large conveying pulley 85, a reproducing unit conveying roller 115, and a toothed belt 116 for rotation.

As shown in FIG. 16, when the card 3 is conveyed and is sandwiched between the first corner conveying roller 99 and the corner tension roller 97, the corner tension roller 97 is opposed to the urging spring 112 and the card path is moved. Extruded from. Here, the sliding direction S of the corner tension roller 97 is the same angle θ with respect to each of the corner transport rollers 99 and 100, so that the distance between the corner first transport roller 99 and the corner tension roller 97 is equal to the thickness of the card 3. As a result, the space between the second corner conveying roller 100 and the corner tension roller 97 is also substantially the same. At this time, all the urging forces of the urging springs 112 act between the corner tension roller 97 and the corner first transport roller 99 to pinch the card 3. As a result, the card 3 can be clamped at about twice the pressure before taking in, so that the card 3 can be held even in the corner portion 98 where the conveyance resistance is large.
Can be prevented from changing.

Further, when the card 3 is conveyed and taken in by the corner second conveying roller 100, the corner second
Since there is a gap between the transport roller 100 and the corner tension roller 97, it is possible to easily take in the paper.
Can be prevented from changing.

When the card 3 is further conveyed and separated from the first corner conveying roller 99 and nipped by only the second corner conveying roller 100, a gap is formed between the first corner conveying roller 99 and the corner tension roller 97. Occurs. Thereby, the corner second transport roller 100
And the card 3 can be clamped by the corner tension roller 97 with a pressure about twice as high as that before taking in.
It is possible to prevent the speed of the card 3 from changing even at the corner 98 where the conveyance resistance is large.

As shown in FIGS. 6 and 7, the downstream end of the third guide 28 is located between the first corner conveying roller 99 and the second corner conveying roller 100. The fourth guide 29 is bent at a right angle in an arc shape along the corner tension roller 97 and continues to the printing unit 12. Further, the fifth guide 30 is provided with the storage mechanism 14.
Through the corner second transport roller 100 to the printing unit 12.

Here, from the storage mechanism 14 to the third guide 28
The selector 117 is provided up to the downstream end of the selector 117. The selector 117 is a flat plate-shaped leaf spring as shown in FIG. 31 and has an end on the storage mechanism 14 side, that is, an upper end 117a.
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 third guide 28, and is located on the card conveying surface of the fourth guide 29. The selector 117 is normally located below by a spring pressure to close the card passage. And
When the card 3 is transported in the forward direction, the selector 117
Pushes the lower end portion 117b of the upper end portion of the upper end portion of the upper end portion 117b to pass through the corner portion 98. When the card 3 is conveyed from the write / read section 11 in the reverse direction, the card 3 is guided upward by the lower end 117 b of the selector 117 and is not taken in by the corner first conveying roller 99 and the corner tension roller 97. It is transported to the storage mechanism 14.

In the card path near the upper end of the selector 117, a reject transport roller 118 and a tension roller 119 for pressing the card 3 against the reject transport roller 118 are arranged to face each other. The reject transport roller 118 is rotatably supported by the fourth side plate 82 and the base plate 16. The reject conveyance roller 118 is connected to the first corner conveyance roller 99 by a gear as shown in FIG. Therefore, for example, when the card 3 is transported in the reverse direction in FIGS. 6 and 7, the corner transport rollers 99 and 100 are rotated clockwise, and the reject transport roller 118 is rotated counterclockwise to rotate the card 3. 3 is transported to the storage mechanism 14. Further, the tension roller 119 is attached to the holder 120.
Are supported rotatably. The holder 120 is rotatably supported by the sixth side plate 114 and the base plate 16. Further, the holder 120 urges the tension roller 119 against the reject conveyance roller 118 by a spring (not shown).

Here, the positional relationship between the upper end of the selector 117 and the reject conveyance roller 118 and the tension roller 119 is, as shown in FIG. When W is a force point, the upper end of the selector 117 is a fulcrum, and the reaction force R to the tension roller 119 is an action point, a ratio m: n between 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 of the card 3 becomes sufficiently heavy just before the card 3 is 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 is possible to prevent the card 3 from jumping up due to ejection and being caught on the upper portion of the reject stacker 121 and being drawn into the card path again by the reject transport roller 118 and the tension roller 119.

A reject sensor 25 attached to the door 18 is disposed in a card path sandwiched between the transport roller 118 and the tension roller 119. The reject sensor 25 detects whether or not the discharged card 3 has passed through the transport roller 118 and the tension roller 119, that is, whether or not the card 3 has been correctly discharged.

The regulating guide 122 is provided on the extension of the selector 117, that is, on the upper side along the ejection direction of the card 3. For this reason, as shown in FIG. 18, even when the card 3 is curving upward due to curl when being ejected by the reject conveyance roller 118, the curving of the card 3 is corrected downward by the regulating guide 122.
For this reason, it is possible to prevent the discharged card 3 from stalling, being stuck on the upper portion of the reject stacker 121, and being drawn into the card path again. Moreover, since the ejected cards 3 are stacked in order, it is possible to easily manage defective cards and the like.

The regulating guide 122 is formed integrally with the cover plate 32 as shown in FIG. For this reason, it is possible to prevent an increase in the number of parts and to prevent the assembly work of the card issuing machine 1 from being complicated. In the present embodiment, the regulation guide 122 is formed integrally with the cover plate 32. However, the present invention is not limited to this.

Here, when the platen lever 143 is rotated to the lowest released state, a part of the platen lever 143 is brought into contact with the door projection 18b of the door 18, as shown in FIGS. ing. Therefore, the door 18 cannot be completely closed while the door 18 is opened and the platen lever 143 is kept lowered. When the door sensor 40 detects that the door 18 is open, the card issuing machine 1 does not operate. Accordingly, when the platen lever 143 is released during maintenance such as cleaning of the print head 129 or when the card 3 is jammed in the printing unit 12, the card issuing machine 1 is operated in the same state, and a defect without printing is performed. A malfunction of issuing a card can be prevented.

When the platen lever 143 is set to the operating position and the door 18 is closed, the door projection 18b
As a result, the lower side of the platen lever 13 cannot be reached, and the release knob 158 of the lock mechanism of the platen lever 13 cannot be operated. Thereby, the platen lever 1

The printed card 3 is conveyed to the card issuing unit 13. The card issuing unit 13 includes an issuing roller 145
, A tension roller 146 for pressing the card 3 against the issuing roller 145, and a card issuing port 17. The issue roller 145 is connected to the issue motor 147 via a motor pulley 148, a toothed belt 149, and a pulley 150 and rotated. For this reason, when the issuing motor 147 is driven, the issuing roller 145 rotates and the completed card 3 is issued from the card issuing port 17. Here, an issue sensor 151 is attached to a card path near the issue roller 145. This issuance sensor 151
By this, it is detected whether or not the card 3 has been issued away from the issuing roller 145.

The operation of the card issuing machine 1 will be described. First, as shown in FIGS. 1 and 2, the roll paper 2 is loaded. In this loading, the roll core 33 of the roll paper 2 is fitted to the spindle 34 and the roll paper mounting member 36 is fixed to the fixed shaft 35.
It is performed by attaching to. Then, with the door 18 opened, the outer peripheral end of the roll paper 2 is attached to the cutting mechanism 8 through the first taking-in mechanism 5, the loop mechanism 6, and the second taking-in mechanism 7 shown in FIG.

Then, the door 18 is closed and a feed switch (not shown) is pressed to rotate each of the take-in rollers 47 and 55 and the transport motor 83. Here, the roll paper 2 is sequentially cut and transported into cards of the number corresponding to the outermost circumference of the roll paper 2,
This is taken into the storage mechanism 14 and invalidated. this is,
Since the outer peripheral surface of the roll paper 2 is a magnetic surface, a malfunction due to scratches and dirt on the magnetic surface is avoided. When the card 3 is positioned between the fourth guide 29 and the fifth guide 30 by rotating the transport motor 83 in the forward direction, the transport motor 83 is rotated in the reverse direction.
17 and a reject conveyance roller 118.

When the reject operation is completed, the solenoid 89 shown in FIG.
Escapes from the card passage. Then, the roll paper 2 is taken in while being pressed by the push plate 77 to the cutting position, and the card 3 cut by the rotary cutter 68 is in a standby state. Then, each take-in roller 47,5
5 and the conveyance motor 83 are stopped, the solenoid 89 is demagnetized, and the standby tension roller 79 projects into the card path. Thus, the setting is completed.

When the host issues a card issuance command signal, the transport motor 83 is rotated. As a result, the card 3 at the standby position is conveyed, the magnetic data is written by the recording head 123, and the reproduction head 1
24 reads magnetic data. Here, if the reading of data is normal, the card 3 is further conveyed and subjected to thermal printing in the printing unit 12. After that, the card 3 is discharged from the card issuing port 17 through the card issuing unit 13.

If there is an abnormality in reading magnetic data due to scratches or dust on the card 3, the transport motor 83 rotates in the reverse direction and the card 3
7 and is sent to the storage mechanism 14. Thereby, the card 3 in which the abnormality has occurred is taken into the reject stacker 121.

On the other hand, the next card is issued when the rear end of the preceding card has passed the write timing sensor 23.

Here, the held portion of the roll paper mounting member is elastically urged and locked by the locking portion of the fixed shaft, and this locking does not require tightening with a screw member. Regardless of the rotation direction of the roll paper and the spindle, the roll paper can always be held without looseness with respect to the spindle. Therefore, stable supply of roll paper can be performed.

The held portion is elastically biased by the locking portion and locked, and the locking does not require tightening by a screw member, so that the holding force is larger than the biasing force. If the held portion is pulled from the fixed shaft by force, the roll paper mounting member can be removed from the spindle. In this state, the roll paper can be attached to and detached from the spindle.
For this reason, the replacement operation of the roll paper can be performed quickly with one touch, and the workability can be improved.

Further, since the held portion is elastically urged by the locking portion and locked, the locking portion rotates for a long time when the held portion rotates with respect to the fixed shaft. Friction is given. Therefore, when the pulling of the roll paper is stopped, the roll paper stops due to the friction between the held portion and the locking portion. As a result, it is possible to reduce the occurrence of slack in the roll paper due to continuous rotation due to the inertia of the roll paper, so that when the transport mechanism is operated next, the roll paper is pulled from the slack state and the slack disappears, and the tension is reduced. The surge can be reduced. For this reason, it is possible to prevent the roll paper from slipping and maintain stable conveyance.

In the roll paper attaching mechanism according to the second aspect, the held portion has an engaging concave portion into which the engaging portion provided on the fixed shaft is fitted and locked, and is formed at the center of the fixed shaft. Since the central shaft is inserted into the central hole, the engaging portion is engaged with the engaging concave portion having a step in the attaching / detaching direction of the held portion. Thus, the held portion can be securely fixed.

Further, in the roll paper mounting mechanism according to the third aspect, the pressing portion presses the peripheral edge of the center hole of the roll paper from the side by the elastic urging of the engaging concave portion and the locking portion, and fixes the roll paper to the spindle. The pressing part presses the peripheral edge of the center hole of the roll paper from the side and fixes it to the spindle by applying the urging force in the direction of
The roll paper can be securely fixed to the spindle without rattling. Thereby, stable supply of roll paper can be performed.

Further, in the roll paper mounting mechanism according to the fourth aspect, since the locking portion is a plurality of balls urged toward the rotation center by the spring, the ball is locked to the held portion. . Therefore, rotation of the held portion with respect to the fixed shaft can be made smooth, and the held portion can be easily removed with one touch. In addition, since a light feeling of moderation can be obtained by locking the ball and the held portion,
Operation feeling can be improved.
