DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card feeding mechanism for moving a flexible card from a first linear transport path to a second linear transport path by passing through a bent portion having a predetermined angle. More specifically, the present invention relates to a card feeding mechanism suitable for running a card formed by cutting roll paper at a bent portion.

[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, such a card issuing machine has a bent portion 200 in which a card passage inside the device is bent at a right angle, for example, in order to reduce the size of the device.

In the bent portion 200 of the card passage, the transport resistance of the card is larger than that in the straight portion 201, so that the card is likely to be jammed. In order to prevent the occurrence of the jam, a roller set is provided on each of the upstream portion and the downstream portion of the bent portion 200 in the card transport direction F. The first drive roller 202 and the first tension roller 20 sandwiching the card path are provided on the upstream side of the bent portion 200.
3 is provided with a first set of rollers 204. The second drive roller 205 and the second tension roller 20 sandwiching the card path are provided on the downstream side of the bent portion 200.
6 is provided.

[0004] Outside the bent portion 200, each drive roller 2
02 and 205 are installed. Each drive roller 202, 2
The diameter of 05 is large enough to allow the drive rollers 202 and 205 to easily take in the card.

Further, tension rollers 203 and 206 are provided inside the bent portion 200. Here, assuming that the diameter of each tension roller 203, 206 is equal to the diameter of the opposing drive roller 202, 205 in order to make it easier to take in the card into each roller set 204, 207, as shown by a two-dot chain line in the figure, the tension roller 203 ', 206'
They overlap each other. For this reason, the diameters of the tension rollers 203 and 206 are set so as not to overlap each other.

Further, in order to prevent the speed difference of the card from being caused by the large transport resistance at the bent portion 200, the pad pressure at each of the roller sets 204 and 207 is set to the pad pressure at the other portion of the card path. It is set larger than.

[0007]

However, in the above-described mechanism for transporting the card at the bent portion 200, the first roller set 204 and the second roller set 207 are separately provided, and each drive roller 202 is provided. , 205 and the tension rollers 203, 206 have different diameters and apply a large pad pressure.
When the sheet passes through the roller set 204 and reaches the second roller set 207, the take-in is not performed smoothly, and there is a possibility that a speed variation of the card may occur. Further, when the rear end of the card is disengaged from the first roller set 204, the card is rapidly pushed out. At this time, although the central portion of the card is sandwiched by the second roller set 207, there is a possibility that a speed variation of the card may occur. .

If a speed variation occurs on the card, adverse effects such as a change in the recording interval when magnetic data is recorded on the card may occur, so that the occurrence of the speed variation must be prevented.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a card feeding mechanism capable of preventing the occurrence of a speed variation of a card at a bent portion where the transport resistance of the card is large.

[0010]

According to a first aspect of the present invention, there is provided a card feeding mechanism for transferring a flexible card from a first linear conveyance path to a second card via a bent portion having a predetermined angle. And a first drive roller and a second drive roller disposed inside the bent portion and a first drive roller and a second drive roller disposed outside the bent portion. And a gap between the second drive roller and the common roller when the card is sandwiched only between the first drive roller and the common roller, and the second drive roller and the common roller. The common roller is movably held so that a gap is formed between the first driving roller and the common roller when the card is sandwiched only between the first driving roller and the first driving roller. So that and a holding means for urging between the beauty second drive roller.

Therefore, when the card is not sandwiched between each drive roller and the common roller, the urging force of the common roller is divided by each drive roller. Then, when the card is transported from the first linear transport path to the bent portion, the leading end of the card is taken in between the first drive roller and the common roller. At this time, since the pad pressure between the common roller and the first drive roller is about half of the urging force of the holding means,
Cards can be easily taken in.

The card is sandwiched only by the common roller and the first driving roller, so that the common roller is pushed out of the card path by the thickness of the card and moves the holding means. This creates a gap between the second drive roller and the common roller. Here, since the urging force of the common roller by the holding means all acts on the first driving roller, the pad pressure for holding the card is about twice as large as that in the case where the pressure is divided before the card is taken in.

When the card is further transported, the leading edge of the card is taken in between the second drive roller and the common roller.
At this time, since a gap is formed between the second drive roller and the common roller, the leading end of the card is taken into this gap. Therefore, the card can be smoothly taken in.

When the card is further conveyed, the rear end of the card is located between the first drive roller and the common roller. The card escapes from between the first drive roller and the common roller and is held by only the second drive roller and the common roller. At this time, a gap is maintained between the first drive roller and the common roller. Here, since all the urging force of the common roller by the holding means acts on the second drive roller, the pad pressure for holding the card is about twice as large as that in the case of partial pressure. For this reason, when the rear end of the card comes out of the space between the first drive roller and the common roller, a sudden pushing force acts, but at the same time, the pad pressure of the second drive roller and the common roller becomes about twice, so that the card Can be prevented from occurring.

Further, when the card is conveyed, the rear end of the card is located between the second drive roller and the common roller.
Then, the card comes out of the space between the second drive roller and the common roller, and is conveyed from the bent portion to the second linear conveyance path.

Further, in the card feeding mechanism according to the second aspect, the contact point between the first drive roller and the common roller is formed by the bent portion and the first drive roller.
Is slightly closer to the bent portion than the boundary of the
The contact point between the drive roller and the common roller is located at the boundary between the bent portion and the second linear transport path. Therefore, the leading end of the card is taken in by the first drive roller and the common roller when the card slightly enters the bent portion from the first linear transport path. When the leading end of the card reaches the boundary between the bent portion and the second linear transport path, the card is taken in by the second drive roller and the common roller.

Furthermore, in the card feeding mechanism of the third aspect,
The holding means includes a tension lever that is slidable in a direction perpendicular to a line connecting the rotation centers of the first drive roller and the second drive roller and that is position-adjustable in a line direction connecting the rotation centers. I have to. Therefore, the first
When the card is sandwiched only between the driving roller and the common roller, the tension lever is moved to the first driving roller and the second driving roller.
A gap can be formed between the second drive roller and the common roller by sliding the drive roller in a direction orthogonal to a line connecting the rotation centers of the drive roller. Further, when the card is sandwiched only between the second driving roller and the common roller, the tension lever is slid in a direction perpendicular to a line connecting the rotation centers of the first driving roller and the second driving roller. A gap can be formed between the first driving roller and the common roller.

Further, by adjusting the position of the tension lever in the direction of the line connecting the rotation centers, the urging force of the common roller with respect to the first drive roller and the second drive roller can be made uniform. For this reason, when the card is transported by the two rollers of the first drive roller and the second drive roller, it is possible to eliminate a speed change due to slippage of the card between the first drive roller and the second drive roller. it can.

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. 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,
It is possible to change a moderation feeling and an operation feeling at the time of attaching and detaching the held portion 38. That is, as in the present embodiment, the ball 43
When a steel ball is used for the ball 43, a crisp and firm moderation feeling can be obtained, while 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 face of the held part 38 opposite to the insertion direction with the holding part 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.

Roll paper mounting mechanism 4 and first take-in roller 4
7 between the mounting sensor 2 attached to the door 18.
0 is arranged. The mounting sensor 20 can detect whether the roll paper 2 is mounted or whether the roll paper 2 has been completely used and has been lost.

Then, the roll paper 2 taken out from the roll paper mounting mechanism 4 is drawn into the first take-in mechanism 5.
As shown in FIG. 9, the first take-in mechanism 5 includes a first take-up roller 47, a drive motor 48 including a DC motor for rotating the first take-up roller 47, and a first take-up roller 47. And a tension roller 49 for pressing the paper 2. The first intake roller 47 is rotatably supported by the first side plate 50 and the base plate 16. The first intake roller 47 is connected to a drive motor 48 by a gear train 156 and rotates. The tension roller 49 is the holder 5
1 rotatably supported. The holder 51 is swingably supported by the second side plate 52 and the base plate 16. Further, the holder 51 uses a spring (not shown) to connect the tension roller 49 to the first intake roller 47.

6 so as to be rotatable. The support position is such that the loop lever 54 straddles the shortest path (indicated by a dashed line in FIG. 10) of the roll paper 2 between the first intake roller 47 and the second intake roller 55. And the loop lever 5
A guide protrusion 56 is formed on the back side of the fourth. Also,
The base plate 16 facing the guide protrusion 56 has a structure shown in FIG.
As shown in FIG. 13, an arc-shaped slide hole 57 is formed. 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. 5
3 presses down the roll paper 2 by its own weight, and the loop lever 54 is in 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.
The loop lever 54 can be slid up and down as shown in FIG. Also in this case, the loop lever 54 'is straddled over the shortest path of the roll paper 2 between the first take-in roller 47 and the second take-up roller 55, so that when the roll paper 2 is mounted, the loop lever 53' is forgotten to be hung on the loop roller 53. Can be prevented.

As shown in FIG. 9, the second taking-in mechanism 7 includes a second taking-in roller 55, a driving motor 60 composed of a stepping motor for rotating the second taking-in roller 55, and a second taking-in roller. 55 is provided with a tension roller 61 for pressing the roll paper 2.

And are connected by The tension roller 61 is rotatably supported by a holder 65. This holder 6
5 is swingably supported by the third side plate 66 and the base plate 16. Further, the holder 65 is held by the tension roller 61 by an urging spring 67 composed of a torsion coil spring.
To the second intake roller 55.

The cut positioning sensor 21 attached to the door 18 is arranged between the second intake roller 55 and the cutting mechanism 8. The cut positioning sensor 21
By detecting a hole formed in the roll paper 2, the roll paper 2 is transported to the cutting mechanism 8 by a length corresponding to one card.

Further, a cut length sensor 22 attached to the door 18 is disposed downstream of the card standby section 9. When the leading end of the roll paper 2 is detected by the cut length sensor 22, the cut mechanism 8 is operated to cut the roll paper 2 to produce the card 3.

The cutting mechanism 8 includes a rotary cutter 68 and a drive motor 69, as shown in FIGS. As shown in FIG. 14, the rotary cutter 68 includes a fixed blade 71 fixed to a bracket 70 and a fixed blade 7 fixed to the bracket 70.
The rotary blade 72 includes a rotary blade 72 provided in a rotatable manner in parallel with the rotary blade 1 and a cutter arm 73 fixed to one end of the rotary blade 72. The rotary blade 72 has a D-shaped cross section obtained by chamfering a part of a cylinder. And the chamfered surface 72a of the rotary blade 72
The roll paper 2 is passed between the fixed blade 71 and one side edge of the fixed blade 71, and the rotary blade 72 is rotated to cut the roll paper 2 by the shearing force between the fixed blade 71. The cutter arm 73 has a longitudinal groove 73a. A cam roller 75 on a cam ring 74 rotated by a drive motor 69 is inserted into the groove 73a. Therefore, the rotation of the drive motor 69 causes the rotary blade 72 to rotate via the cam ring 74, the cam roller 75, and the cutter arm 73, thereby cutting the roll paper 2. The roll paper 2 is cut into the card 3.

On the back side of the base plate 16, a cutter sensor 76 for detecting the position of the cutter arm 73 is attached. The cutter arm 73 is provided by the cutter sensor 76.

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.

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. 5 and 6, 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 intake 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 issue command signal, the transport motor 83 is rotated. Thus, the card 3 at the standby position is transported to the bent portion 98.

Here, when the card 3 is not sandwiched between the driving rollers 99 and 100 and the common roller 97, the urging force of the common roller 97 by the urging spring 112 is equal to the driving rollers 99 and 100. Partial pressure. Then, when the leading end of the card slightly enters the bent portion 98 from the first linear conveyance path 159, the card is taken in by the first drive roller 99 and the common roller 97. At this time, the pad pressure between the common roller 97 and the first drive roller 99 is adjusted by the biasing spring 11
Since the urging force of the card 2 is about half, the card 3 can be easily taken in.

Then, as shown in FIG. 1, when the card 3 is conveyed and sandwiched between the first drive roller 99 and the common roller 97, the common roller 97 is pushed out of the card path by the thickness of the card 3. It moves together with the holding means 161 against the urging spring 112. Here, since the sliding direction S of the common roller 97 is the same angle θ with respect to each of the driving rollers 99 and 100, the distance between the first driving roller 99 and the common roller 97 is increased by the thickness of the card 3 so that the sliding direction S is increased. The space between the second drive roller 100 and the common roller 97 is also substantially the same.
At this time, all the urging forces of the urging springs 112 are applied to the common roller 9.
Act between the first drive roller 7 and the first drive roller 99 to pinch the card 3. As a result, the pad pressure for holding the card 3 can be approximately doubled before the card is taken in, so that the speed of the card 3 can be prevented from changing even at the bent portion 98 having a large conveyance resistance.

Further, when the card 3 is conveyed, the card 3 is taken into the second drive roller 100 and the common roller 97 when the leading end of the card 3 reaches the boundary between the bent portion 98 and the second linear conveyance path 160. . At this time, the second drive roller 1
Since there is a gap G between the second roller 00 and the common roller 97, the card 3 can be easily taken in. For this reason, the card 3 can be smoothly taken in, and the speed of the card 3 can be prevented from changing even at the bent portion 98 having a large conveyance resistance.

When the card 3 is further conveyed, the rear end of the card 3 is located between the first drive roller 99 and the common roller 97. The card 3 escapes from between the first drive roller 99 and the common roller 97 and the second drive roller 100
And the common roller 97 alone. At this time,
A gap is maintained between the first drive roller 99 and the common roller 97. Here, since all the urging force of the urging spring 112 acts on the second drive roller 100, the pressure is about twice as large as that in the case where the pad pressure for clamping the card 3 is divided. Therefore, when the rear end of the card 3 comes out of the space between the first drive roller 99 and the common roller 97, a sudden pushing force is applied. At the same time, the pad pressure of the second drive roller 100 and the common roller 97 is reduced. Since the speed is approximately doubled, it is possible to prevent the speed displacement of the card 3 from occurring.

Further, when the card 3 is conveyed, the rear end of the card 3 is located between the second drive roller 100 and the common roller 97. Then, the card 3 is moved to the second drive roller 10
When the paper exits between the zero and the common roller 97, the paper is conveyed from the bent portion 98 to the second linear conveyance path 160.

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 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 conveyance motor 83 rotates in the reverse direction when the error is detected, and the card 3 is switched to the selector 11.
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.
It is started when the take-in roller 55 is rotated. For this reason, the roll paper 2 for preparing the next card 3 is sent from the cutting mechanism 8 to the card standby section 9. The roll paper 2 is cut into cards 3 of a predetermined length by the same operation as described above, and is waited in the card standby unit 9.

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

According to the card feeding mechanism 10 of the present embodiment, when the card 3 is taken into the bent portion 98, the pad pressure between the common roller 97 and the first drive roller 99 is reduced to about the urging force of the urging spring 112. Since it is half, the card 3 can be easily taken in. For this reason, it is possible to prevent the velocity displacement of the card.

When the card 3 is sandwiched only between the first driving roller 99 and the common roller 97, the second driving roller 1
Since a gap G is generated between 00 and the common roller 97, the pad pressure for holding the card 3 can be approximately doubled before the card is taken in. Therefore, it is possible to prevent the speed of the card 3 from changing even at the bent portion 98 having a large transport resistance.

When the card 3 is sandwiched between the first driving roller 99 and the second driving roller 100 with respect to the common roller 97, the pad between the first driving roller 99 and the second driving roller 100 is formed by the common roller 97. Pressure is adjusting plate 10
Since the pressure is equally divided by the adjustment of 4, the paper can be stably conveyed without any speed change due to slippage with the card 3.

Further, the card 3 is moved to the second drive roller 100
When the card 3 is taken in by the common roller 97, the card 3 can be easily taken in because there is a gap G between the second drive roller 100 and the common roller 97. For this reason, the card 3 can be smoothly taken in, and the speed of the card 3 can be prevented from changing even at the bent portion 98 having a large conveyance resistance.

The rear end of the card 3 is connected to the first drive roller 9.
9 and the common roller 97, a sudden pushing force is applied.
Since the pad pressure of 00 and the common roller 97 is approximately doubled, it is possible to prevent the speed of the card 3 from being changed.

On the other hand, the roll paper mounting mechanism 4 of this embodiment
According to this, the held portion 38 of the roll paper attachment member 36 is elastically urged and locked by the locking portion 39 of the fixed shaft 35, and this locking does not require tightening by a screw member. Therefore, regardless of the rotation direction of the roll paper 2 and the spindle 34, the roll paper 2 can always be held without loosening or rattling with respect to the spindle 34. For this reason, stable supply of the roll paper 2 can be performed.

Further, according to the roll paper mounting mechanism 4, the held portion 38 is elastically urged and locked by the locking portion 39, and the locking is performed by a screw member. Since no attachment is required, 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 greater than this urging force.
In this state, the roll paper 2 can be attached to and detached from the spindle 34. 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 38 is elastically urged and locked by the locking portion 39, the held portion 3
When the shaft 8 rotates with respect to the fixed shaft 35, a long-term stable friction is given by the locking portion 39. Therefore, when the pulling of the roll paper 2 is stopped, the roll paper 2 stops due to 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 capture mechanism 5 due to the continuous rotation of the roll paper 2 due to the inertia, so that when the first capture mechanism 5 is operated next time, In this case, it is possible to reduce a situation in which the roll paper 2 is pulled from a slack state to a state in which the slack disappears and the tension is suddenly increased. For this reason, it is possible to prevent the roll paper 2 from slipping and maintain stable transport.

The above embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be made without departing from the spirit of the present invention. For example, in the present embodiment, the card feeding mechanism 10 is employed in the bent portion 98 of a card issuing machine that issues cards at a game store such as a pachinko parlor, but the present invention is not limited to this. And various types of entrance tickets and ticket issuing machines, etc.

[0116]

As is apparent from the above description, the card feeding mechanism according to the first aspect of the present invention provides a flexible card by moving a flexible card from the first linear transport path to the second straight line via a bent portion having a predetermined angle. In a card feeding mechanism adapted to run on a conveying path, a first driving roller and a second driving roller disposed outside a bent portion are provided.
A driving roller, a common roller disposed inside the bent portion and capable of simultaneously abutting on the first driving roller and the second driving roller, and a common roller when the card is sandwiched only between the first driving roller and the common roller. A common roller is formed to form a gap between the second drive roller and the common roller and to form a gap between the first drive roller and the common roller when a card is sandwiched only between the second drive roller and the common roller. Holding means for movably holding the common roller and biasing the common roller toward between the first drive roller and the second drive roller. Is not sandwiched, the urging force of the common roller is divided by the driving rollers. And the card is the first
When the card is taken in between the drive roller and the common roller, the card pressure can be easily taken in because the pad pressure between the common roller and the first drive roller is about half of the urging force of the holding means. . For this reason, it is possible to prevent the velocity displacement of the card.

Since the card is sandwiched only between the first drive roller and the common roller, a gap is generated between the second drive roller and the common roller. Therefore, the pad pressure for sandwiching the card is reduced before the card is taken in. It can be about twice as high as the case of partial pressure. For this reason, it is possible to prevent the card from being speed-displaced even in a bent portion having a large transport resistance.

When the leading edge of the card is taken in between the second drive roller and the common roller, a gap is formed between the second drive roller and the common roller, so that the card can be taken in smoothly. Can be. For this reason, it is possible to prevent the velocity displacement of the card.

When the rear end of the card comes out of the space between the first drive roller and the common roller, a sudden pushing force is applied. At the same time, the pad pressure of the second drive roller and the common roller increases by about twice. Therefore, it is possible to prevent the velocity displacement of the card.

Further, in the card feeding mechanism of the second aspect,
The point of contact between the first drive roller and the common roller is slightly closer to the bend than the boundary between the bend and the first linear transport path, and the point of contact between the second drive roller and the common roller is the bend and the second roller.
At the boundary of the linear transport path, the card is taken in by the first drive roller and the common roller when the leading end of the card slightly enters the bent portion from the first linear transport path, and When the leading end reaches the boundary between the bent portion and the second linear transport path, it is taken in by the second drive roller and the common roller. For this reason, all the cards sent from between the second drive roller and the common roller are located in the second linear conveyance path, so that the cards sent from the card feeding mechanism can be smoothly conveyed. .

In the card feeding mechanism according to the third aspect, the holding means is slidable in a direction perpendicular to a line connecting the rotation centers of the first drive roller and the second drive roller, and connects the rotation centers. Since the tension lever which can adjust the position in the radial direction is provided, when the card is sandwiched only between the first driving roller and the common roller, the tension lever is moved between the first driving roller and the second driving roller. A gap can be formed between the second drive roller and the common roller by sliding in a direction orthogonal to the line connecting the rotation centers. Further, when the card is sandwiched only between the second drive roller and the common roller, the tension lever is slid in a direction perpendicular to a line connecting the rotation centers of the first drive roller and the second drive roller. A gap can be formed between the first driving roller and the common roller.

Further, by adjusting the position of the tension lever in the direction of the line connecting the centers of rotation, the urging force of the common roller with respect to the first drive roller and the second drive roller can be evenly adjusted. For this reason, when the card is transported by the two rollers of the first drive roller and the second drive roller, the transport speed of the first drive roller and the transport speed of the second drive roller can be equalized. Transporting without speed change becomes possible.
