Abstract

PROBLEM TO BE SOLVED: To carry a card by only one motor without using a clutch and two motors and prevent the continous feeding of two pieces by setting the feed out speed of a roller for feeding out the card to bigger than the pay out speed of the roller for paying out the card from a stacker. SOLUTION: This device is provided with a first roller 21 for exerting the pay out force on the card of the lowest layer of card group piled in a stacker 12, separating from the card group and paying out from a pay out port 30 and a second roller 27A for exerting a feed out force on the paied out card and feeding out to the position received by an utilizer and the feed out speed by the second roller 27A is set to bigger than the pay out speed by the first roller 21. Thus, even when the former card fed out by the second roller and the latter card paied out from the first roller are stayed, an interval can be produced between the former card and latter card and the continuous feed of two cards can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for storing the lowest order card in a group of cards built in a vending machine or the like and loaded on a stacker.
The present invention relates to a card transport device that separates and transports each card.

[0002]

2. Description of the Related Art In order to surely separate and transport cards one by one, a conventional card transport device separates cards stored in a stacker and transports the separated cards out of the stacker by a delivery roller and a delivery roller. A sending roller for sending the card further to a position available to the user, means for driving two motors or a feeding roller comprising one motor and a clutch and a sending roller, and one detection sensor for detecting the card. I had it.

In transporting cards, in order to prevent continuous feeding of two cards, that is, to ensure that the cards are separated and transported one by one, the feeding roller and the feeding roller are rotated to detect the card. When the sheet is conveyed to the sensor and is shielded from light by the detection sensor, the rotation of the feed roller is first stopped at that time, and then the delivery roller is stopped after a certain period of time or the light emitted from the sensor. The card sent out by the sending roller to a position where the user can obtain the card and stopped is extracted by the user.

[0004]

According to the card conveying apparatus described above, two motors or one motor and a solenoid for driving a clutch and a clutch are provided as drive means for the feeding roller and the delivery roller. Therefore, miniaturization and cost reduction of the apparatus were not sufficient. Accordingly, the present invention provides a small and inexpensive card transport device that does not include a clutch or the like, has only one motor, can drive a feeding roller and a delivery roller to transport a card, and can prevent continuous feeding of two cards. The purpose is to provide.

[0005]

In order to achieve the above object, a card transporting apparatus 1 according to the first aspect of the present invention, as shown in FIG. 1, has a stack including a top card and a bottom card. And a stacker 12 having a pay-out port 30 for receiving the card group of the bottom layer and feeding out the card of the lowermost layer; applying a repeating output to the card of the lowermost layer to separate the card from the card group; A first roller 21 which feeds the card fed through the feed roller 30; and a second roller 27A which feeds the card fed from the feed port 30 by applying a feed power to the card. The feed speed of the second roller 27A depends on the first roller 21. It is characterized in that it is set higher than the feeding speed.

[0006] With this configuration, the sending speed of the second roller is set to be higher than the feeding speed of the first roller. Thus, even if there is a card that has been fed out, an interval can be created between the previous card and the subsequent card, and continuous feeding of two cards can be prevented.

According to a second aspect of the present invention, there is provided a card transporter according to the first aspect, wherein the card is provided between the outlet and the second roller, and is fed out of the outlet. And a second detection sensor for detecting the sent out card; the first detection sensor and the second sensor are used to feed out or send out the card. The card is configured to detect clogging of a card.

According to this structure, the lowermost card separated one by one is detected by the first detection sensor, then detected by the second detection sensor in the process of being fed out and sent out, and then detected. It is no longer detected by the first detection sensor, and then is not detected by the second detection sensor. If the process does not proceed in the order of these steps, or if it exceeds a predetermined time before proceeding to the next step, it is determined that the card is clogged including one caused by continuous feeding of two cards depending on the situation, and for example, the drive source. This can be dealt with by reversing the motor, which can be eliminated. The first sensor receives the output from the feeding roller to detect the fed card, and the second sensor detects the card fed from the feeding roller and further receives the sending output from the sending roller to detect the sent card.

According to a third aspect of the present invention, in the card transporting apparatus according to the first or second aspect, the first roller and the second roller are driven by one driving device. (1) When the first roller and the second roller contact one card at the same time, the transmission output is given priority over the repetition output.

With this configuration, in a situation where the repetitive output by the first roller and the repetitive output by the second roller are simultaneously applied to one card, the repetitive output is applied to the card prior to the repetitive output. Since the driving device for the first roller and the driving device for the second roller are the same and one, the apparatus can be made smaller and inexpensive.

According to a fourth aspect of the present invention, in the card transporting device according to any one of the first to third aspects, the contact portion of the lowermost card which contacts the first roller is provided. The contact portion is located on a side opposite to the feeding port from a center of a surface of the lowermost card.

[0012] With this configuration, the contact portion of the lowermost card in contact with the first roller is disposed on the opposite side of the center of the card surface from the feeding port. When contacting the card to apply repetitive output, the rear end of the card opposite to the repetition exit rises,
The attitude of the card to be fed out is stable without the leading end on the feeding port side rising, and the card to be fed can pass through the feeding port smoothly.

The feed roller shaft 20 vertically penetrates the side surface of the feed roller 21 at a position eccentric from the center. The bottom wall 17 has an opening 23, and when the feed roller 21 is rotated, the stacker 12 is opened from the opening 23 at a predetermined time in the cycle.
A part of the card protrudes inside, contacts the lower surface of the lowest card, and applies a repetitive output to the card to draw out the card. When the feeding roller 21 applies a repeating output to the card,
Generally, the feeding roller 21 is in contact with the card while rotating.

The delivery mechanism 25 includes a lower delivery roller shaft 26A and a lower delivery roller shaft 2 that are horizontally supported.
6A, a lower delivery roller 27A as a second roller attached to the center in the longitudinal direction, and the lower delivery roller shaft 26A and the lower delivery roller 27A are located below the card guide path 24 in the roller storage section. 13. The delivery mechanism 25 further includes an upper delivery roller shaft 26B and an upper delivery roller shaft 26 that are horizontally supported.
Upper delivery roller 27 attached to the center in the longitudinal direction of B
B, and the upper delivery roller shaft 26B and the upper delivery roller 27B are arranged in the motor housing 14 above the card guide path 24.

The lower delivery roller shaft 26A penetrates the side wall 12D of the roller housing 13 and protrudes to the outside of the roller housing 13, and an end of the protruding portion has a pulley 2A.
8A (see FIG. 2) is attached. The lower delivery roller shaft 26A vertically penetrates the center of the lower delivery roller 27A. Two roller pins 50A, D and four roller pins 50B, C, E, F are attached to the side surface of the lower delivery roller 27A at an equal distance from the center at every 60 degrees, and vertically penetrate the side surface. I have. The roller pin 50D is attached at a distance of 180 degrees from the roller pin 50A, protrudes from both side surfaces of the lower delivery roller 27A, and the protruding lengths of both side surfaces are equal to each other (see FIG. 2). The roller pins 50B, C, E, and F protrude only from the side surface of the lower delivery roller 27A opposite to the side wall 14A (see FIG. 2). The upper delivery roller shaft 26B also has an upper delivery roller 27 like the lower delivery roller shaft 26A.
B penetrates vertically through the center. The upper delivery roller shaft 26B is not connected to the driving machine, and the upper delivery roller 27B rotates freely.

One end of the upper delivery roller shaft 26B of the upper delivery roller 27B is rotatable on one end 53A of a plate-like upper delivery roller support plate 53 having an inverted "-" shape in FIG. Attached to. The upper delivery roller support plate 53 penetrates the central portion 53B and is attached to the horizontally arranged upper delivery roller support pin 54,
The upper feed roller support pin 54 is attached to a lower portion of the side wall 14A so as to be vertically fixed to the side wall 14A. The upper delivery roller support plate 53 is attached to the upper delivery roller support pin 54, and is partially rotatably fixed in a plane perpendicular to the upper delivery roller support pin 54. A spring pin 55 is mounted on a surface on the side of the side wall 14A of the other front end portion 53C of the upper sending roller support plate 53 so as to be perpendicular to the mounting surface thereof, that is, horizontally (see FIG. 2).

A spring 56 urged in the contraction direction has one end connected to the spring pin 55 and the other end attached to an upper portion of a projection plate 47A projecting from the front end wall 12A at right angles to the front end wall 12A in the extending direction. It is arranged so as to be connected to the attached spring pin 57. Due to the contraction force of the spring 56, the upper delivery roller support plate 53 rotates around the upper delivery roller support pin 54 in a counterclockwise direction in FIG. 1, and presses the upper delivery roller 27B toward the lower delivery roller 27A. When the card passes between the lower delivery roller 27A and the upper delivery roller 27B, the upper delivery roller 27B moves upward by approximately the thickness of the card. The movement of the upper delivery roller 27B acts in the direction of pulling the spring 56 via the upper delivery roller support plate 53, and the length of the spring 56 increases. After the card passes, the upper delivery roller 27B moves downward due to the contraction force of the spring 56, contacts the lower delivery roller 27A, and is pressed against the lower delivery roller 27A.

The card guide path 24 has an opening 29, and the lower sending roller 27A has a part of the circumferential side surface protruding from the opening 29 to come into contact with the lower surface of the fed-out card. Send out the card by applying the sending power.
The card guide path 24 gradually descends vertically downward with respect to the card feeding direction, and the upper surface (uppermost circumferential surface) of the lower sending roller 27A and the bottom wall 17 of the stacker 12 are arranged.
Are placed on a horizontal plane. When the sending roller 27 (the lower sending roller 27A and the upper sending roller 27B) applies sending power to the card, generally, the sending roller 27 is in contact with the card while rotating.

The confirmation sensors S1 and S2 (see FIG. 3) are provided near the upper side of the side wall 13A at a position where the card fed out along the card guide path 24 is vertically sandwiched.
The confirmation sensor S1 and the confirmation sensor S2 are provided in this order from the side closer to 0, and the light receiving units 36B and 37B on the upper side of the card guide path 24 and the light emitting unit 3 on the lower side of the card guide path 24 are provided.

Holes (not shown) are formed in the card guide path 24 corresponding to between the light-emitting portions 36A and 37A and the light-emitting portions 36A and 37A to allow light to pass therethrough.

The motor housing 14 is provided with pulleys 22 and 28A.
14A form one side, the front end wall 12A of the stacker forms one side, and the card guide path 24 forms a bottom. Motor storage unit 1
4, the surface facing the front end wall 12A and the surface facing the side wall 14A are open (see FIG. 2). A cutout portion 14B is provided at substantially the center of the side wall 14A, and a motor 32 as a driving device is horizontally mounted on the cutout portion 14B with its center line arranged perpendicular to the surface of the side wall 14A (see FIG. 2). . The shaft 33 of the motor 32 penetrates the side wall 14A and protrudes from the side opposite to the side wall 14A.
4 is attached. A belt 35 is hung on the pulley 34. The belt 35 couples the pulley 22 and the pulley 28A described above, and drives the feed roller shaft 20 and the lower feed roller shaft 26A, respectively (see FIG. 6).

The lowermost card fed out from the feeding port 30 by the feeding roller 21 is conveyed along the card guide path 24 and sent out by the sending roller 27.
Conveyed. Cards that can pass through the feeding port 30 at a time have the stoppers 31 that are adjusted so that one card can pass from the bottom wall 17 of the stacker 12 as described above.
Only one sheet. The leading end of the fed card in the feeding direction is detected by shielding the confirmation sensor S1 serving as the first detection sensor immediately before the card is sandwiched by the feeding roller 27, and the leading end of the card in the feeding direction of the card sent by the feeding roller 27 is detected. The leading end is detected by shielding the confirmation sensor S2 as a second detection sensor from light, and the rear end of the card (the end opposite to the feeding direction) passes through the confirmation sensor S1, so that the confirmation sensor S1 is thrown. The card is illuminated and the card is not detected. In this state, the motor 32 stops, so that the conveyance of the card is stopped, the card waits at that position, and then when the user removes the card, the rear end of the card passes the confirmation sensor S2, and the confirmation sensor S2 is turned off. The light is emitted and the card is not detected. The detection by the confirmation sensor means light shielding, and the non-detection means light projection.

The cards in the stacker 12 are fed by the feeding rollers 21.
In a series of operations performed by the feeding roller 27, the feeding speed of the feeding roller 27 is made faster than the feeding speed of the feeding roller 21 so that even if the card is continuously fed, the end of the first sheet is obtained. An interval is formed between (the opposite side in the traveling direction) and the tip of the second sheet (in the traveling direction). It is assumed that the feeding speed of the feeding roller 21 is lower than the feeding speed of the feeding roller 27 which should be the same, and if the output of the motor 32 is the same, the feeding roller 2
It can be said that the repetition output of No. 1 has increased.

Here, the feeding speed of the feeding roller is obtained by multiplying the rotation speed of the feeding roller by the distance between the rotation center of the feeding roller and the contact portion of the feeding roller with the card. The delivery speed of the delivery roller is obtained by multiplying the rotation speed of the delivery roller by the distance between the rotation center of the lower delivery roller and the contact portion of the lower delivery roller with the card.

The lever 40 has two lever plates 40A arranged in parallel. As shown in FIG. 7, a lever support pin 45 is provided in the feed port 30 of the front end wall 12A of the stacker 12 on the motor housing portion 14 side. Can be partially rotated around
It is urged by a spring and attached to the opposite side of the feeding direction. The lever support pin 45 is horizontally arranged and attached to a projection plate 47A and a projection plate 47B projecting from the front end wall at right angles to the front end wall 12A in the extending direction. The projection plate 47A is located closer to the side wall 14A than the projection plate 47B.

Next, the transfer of the card and the position of the lever will be described. In the standby state, the lever 40 is in a state of contact with the roller pin 50B on the side of the feed port 30 and is in contact with the leading end of the roller pin 50B that is in contact with the roller pin 50B on the side of the port 30. Between the positions CC, the two slits 41 formed in the card guide path 24 are positioned such that their leading ends are down.

When the feeding of the card (not shown in FIG. 7) is started, the lever 40 is pushed from one of the standby states by the end of the card in the feeding direction, starts moving, and rides on the upper surface of the card. BB is located in a state where the card is pressed against the card guide path 24. In this state, when the card is pulled out by the customer and the end of the card opposite to the payout direction is moved to a position ahead of the position BB, the lever 40 is moved.
Is quickly returned to the position of AA in the standby state by the urging force of the spring.

The lever 40 has its tip positioned below the card guide path 24, thereby preventing the card from being inserted into the stacker 12 due to an error or mischief by the user.

Next, the problem of the speed difference between the rollers (the feed roller 21 and the feed roller 27) will be described. In order to be able to provide the aforementioned speed difference for each roller,
Has a structure in which, during rotation, the rotation speed of the feeding roller shaft 20 driven by the motor 32 in the direction of rotation can be further rotated by a predetermined angle. Further, the rotation of the feeding roller 21 is eccentric in order to intermittently feed the card, and the card is contacted with the lowest card in order to be further fed by the sending roller 27 before the feeding of the card by the feeding roller 21 is completed. The feed amount per one rotation to be fed out from the feeding port 30 of the stacker 12, that is, the distance L from the position of the stopper 31 to the position of the feed roller 27 is α.
Was added.

After the card is fed by the feeding power of the feeding roller 21 by a distance L, the card is sandwiched by the feeding roller 27 and fed by the feeding power of the feeding roller 27. The card is also in contact with the feeding roller 21 while the card is advanced by the distance α after being sent out by the sending roller 27, but the feeding output acts on the repeating output in priority, and the repeating output does not act on the card. That is, the card is transported at the feeding speed by the distance L, and thereafter, is transported at the feeding speed while being in contact with the feeding roller 21 and the feeding roller 27 while the card is advanced by the distance α. That is, while the distance α is being advanced, the feeding roller 21 rotates in contact with the card at a speed higher than the feeding speed. During this time, since the feeding roller shaft 20 is driven by the motor 32 at a rotation speed corresponding to the feeding speed, the feeding roller 21 advances ahead of the feeding roller shaft 20, and slippage occurs between the two. The specific structure that makes this possible will be described later. A specific numerical value of the feed amount (L + α) of the card conveyed per rotation of the feeding roller while the card is in contact with the feeding roller 21 is 30 mm.

The feeding roller 21 acts only on the lowest card in one rotation, and does not act on the second card during conveyance by the sending roller 21, so that the cards are reliably separated and fed one by one. Have been. This will be described below with specific numerical values.

The rotation speed of the motor 32 is 120 rpm, that is, 2 rpm. The diameter of the feeding roller 21 is 26 mm,
The diameter of the lower delivery roller 27A is 30 mm. The gear ratio of the pulley 34 of the motor 32, the pulley 22 of the feeding roller 21, and the pulley 28A of the lower delivery roller 27A is 40: 2.
6 to 40. Here, the second card is conveyed only by the feeding roller 21 and the first card is sent by the sending roller 2.
7, it is assumed that the feed roller 21 is not eccentric to the feed roller shaft 20 and is attached at the center thereof.

The number of revolutions per second of the delivery roller is 2 × (26/40) = 1.3 rps The number of revolutions per second of the delivery roller is 2 × (40/40) = 2 rps The delivery speed of the delivery roller is 26 × π × 1.3 = 106.18 mm / s (1 mm
The delivery time per unit is 9.42 ms / mm. The delivery speed (delivery speed of the delivery roller and the delivery roller) is 30 × π × 2 = 188 mm / s (the delivery time per 1 mm is 5. 32 msec / mm) The feed amount per rotation of the feed roller is 26 × π = 81.68 mm The feed amount of the feed roller per rotation of the feed roller is 30 × π × (46/26) = 144.99. mm, and a feeding roller 1 is provided between the first card and the second card.
There will be an interval of about 63 mm per revolution.

Next, with reference to FIG. 5, the driving mechanism of the feeding roller 21 will be described. As shown in FIGS. 5A and 5B, the feed roller 21 is attached to the feed roller shaft 20, and the feed roller 21 is connected to the feed roller shaft 20.
It is rotatable with respect to. Feeding roller shaft 2
0 penetrates the eccentric position of the feeding roller 21. Two driven pins 38 are erected vertically on one side surface of the feeding roller 21, and one driving pin 39 is passed through the feeding roller shaft 20 in a state perpendicular to the longitudinal center line of the feeding roller shaft 20. Stand up. Each tip of the drive pin 39 is at an equal distance from the circumference toward the center when viewed from the longitudinal direction of the feeding roller shaft 20. FIG. 5 (B) is FIG. 5 (A)
FIG.

As shown in FIG. 5A, when the shaft center is higher than the roller center, the feeding roller 21 is not in contact with the lower surface of the lowest card 2 in the stacker 12. In the drawing, the feeding roller 21 rotates clockwise as indicated by an arrow. The feeding roller shaft 20 driven by the pulley (not shown in FIG. 5A) rotates, and when the feeding roller shaft 20 rotates, the driving pin 39 rotates, and the driving pin 39 is connected to the two driven pins 38. Because it touches one side,
The feeding roller 21 rotates. The feeding roller 21 is shown in FIG.
5A, the circumference of the rotating feeding roller 21 gradually approaches the lower surface of the lowermost card 2 and, when rotated by a predetermined angle as shown in FIG. The card 2 comes into contact with the lower surface of the card 2 and receives the repetitive output from the feed roller 21 after the contact, and is fed rightward in FIG.

When the feeding roller 21 rotates from the state shown in FIG. 5 (C), the card 2 is fed in the feeding direction, and the end 2B of the card 2 which is opposite to the feeding direction is directed upward to the bottom wall 17 (see FIG. 1). ), The end 2 of the card 2 in the feeding direction
Since A is kept in contact with the bottom wall 17 and is located below the end 2B, the card 2 is slightly inclined. When the feeding roller 21 is in contact with the card 2, the feeding roller 21 is arranged such that the contact portion is closer to the end 2 B than the center of the surface of the card 2. Occurs, and the end 2A is conveyed in contact with the bottom wall 17 and smoothly enters and passes through the outlet 30.
Here, the center of the surface refers to a small area including a center line perpendicular to the center line in the longitudinal direction which is the card advancing direction on the surface of the card on the feeding roller side. However, it is assumed that the card floats only in the direction about the horizontal axis perpendicular to the above-mentioned feeding direction, and that the card does not tilt around the axis parallel to the feeding direction.

As described above, when the card 2 is fed out and transported by the distance L, the end 2A of the card reaches the delivery roller 27, and the card 2 is sandwiched by the delivery roller 27 and comes into contact with the card to receive the delivery output. . In this state, the vicinity of the end 2B of the card 2 is also in contact with the feeding roller 21. Card 2
When the card 2 receives the sending output from the sending roller 27, the sending speed is higher than the feeding speed, and the card 2 is conveyed at the sending speed without receiving the repeating output.

Here, as shown in FIG. 5D, the feed roller 21 rotates at a rotation speed corresponding to the sending speed.
Since the feeding roller shaft 20 is rotating at a rotation speed corresponding to the feeding speed, the feeding roller 21 is further rotated than the feeding roller shaft 20 and the driving pin 39
Are not in contact with the driven pin 38.

The feeding roller shaft 20 is rotating at a constant angular velocity. However, when the feeding roller 21 is driven by the feeding roller shaft 20 and the card 2 is fed, the rotation center of the feeding roller 21 and the card 2 are rotated. Since the distance of the contact point changes depending on the rotation of the feed roller 21, the feed speed is not constant, and when the drive pin 39 comes in the vertical direction, the center of the feed roller shaft 20 is
The feed speed of the feed roller 21 becomes maximum when the feed roller 21 is located below the center of the outer circumference circle 1, but the maximum feed speed is set to be lower than the feed speed.

After the card 2 is fed to the delivery roller 27 and the end 2B of the card 2 is separated from the delivery roller 21, the delivery roller 21 may be given a rotational force from the card 2 (from the delivery roller 27). Since it disappears, the feeding roller 21 stops. The feeding roller 21 is driven to rotate by the rotation of the feeding roller shaft 20, and the driving pin 39 comes into contact with the driven pin 38 again from the stop.

The card conveying device of the present invention sets the conveying speed of each roller as described above, so that the card is not only smoothly conveyed, but also detected by the confirmation sensors S1 and S2 and processed as follows. By doing so, the card is transported smoothly.

FIG. 8 is an operation diagram showing the relationship between the feeding mechanism 18, the feeding mechanism 25, and the confirmation sensors S1 and S2.

First, the operation starts when the card transport device is started (step S01). When the device is started, the motor rotates forward (step S02), and the timer T1 operates (step S03). By the forward rotation of the motor, the feeding roller 21 feeds out the card, and it is determined whether or not the fed-out card shields the confirmation sensor S1 (step S0).
4). If the confirmation sensor S1 is shielded (in the case of YES), the operation of the timer T1 is stopped, and the timer T2 is activated simultaneously with the interruption of the confirmation sensor S1 (step S05). The card is further fed out and sent out by the sending roller 27, and it is determined whether or not the sent-out card shields the confirmation sensor S2 (step S06). Confirmation sensor S
In the case where the light of the second sensor 2 is shielded (in the case of YES), the operation of the timer T2 is stopped, and the timer T3
Operates (step S07).

Next, the card is further sent out by the sending roller 27, and it is determined whether or not the sent-out card has finished blocking light of the confirmation sensor S1, that is, whether or not S1 has emitted light (step S08). When the confirmation sensor S1 emits light (in the case of YES), the operation of the timer T3 stops, and the motor stops simultaneously with the emission of the confirmation sensor S1 (step S3).
09), the card also stops immediately.

At the same time when the motor is stopped, the timer T4 is activated (step S10), and it is determined whether or not the user has removed the card and the card has stopped shading the confirmation sensor S2, ie, whether or not the confirmation sensor S2 has emitted light. (Step S11). When the confirmation sensor S2 is emitted, the operation of the timer T4 stops, and the operation ends because the user has removed the card (step S13). The above is the normal operation without any abnormality.

If it is determined in step S11 that the confirmation sensor S2 does not emit light (NO), it is determined whether the timer T4 has passed a set time (step S12). If not (NO), Returning to step S11, if the user removes the card and the confirmation sensor S2 emits light, the operation ends (step S13), and if it has passed (in the case of YES), the card conveyed to the position of the confirmation sensor S2 is removed. It is determined that the user has forgotten to take it, and the apparatus is abnormally stopped (step S33).

In step S04, if the confirmation sensor S1 is not shielded from light (NO), it is determined whether the timer T1 has passed a set time (step S21), and if not, (NO). Returns to step S04, and if it has elapsed (in the case of YES), it can be determined that the card has not reached the position of the confirmation sensor S1 and is clogged. The motor is set to timer T
5 (step S2).
2) Next, it is determined whether or not the number of reverse rotation operations of the motor has exceeded the set value X (step S23). If not (NO), the process returns to step S02, and the normal rotation operation and the like are performed. When the clogging is completed and the clogging is resolved, the operation shifts to a normal operation. If it exceeds (YES), it is determined that the clogging is not resolved despite the forward and reverse rotations of the motor X times, and the apparatus is abnormally stopped (step S33).

In step S06, if the confirmation sensor S2 is not shielded from light (NO), it is determined whether or not the set time of the timer T2 has elapsed (step S24), and if it has not elapsed (NO). Returns to step S06, and when the time has elapsed (in the case of YES), it is determined that the card has reached the position of the confirmation sensor S1, but has not reached the position of the confirmation sensor S2, and has clogged. Step 22 is executed as follows.

If it is determined in step S08 that the confirmation sensor S1 does not emit light (NO), it is determined whether or not the timer T3 has exceeded a set time (step S25). If it has not elapsed (NO) ) Returns to before step S08, and if it has elapsed (in the case of YES), the card is stuck between the position of the confirmation sensor S1 and the position of the confirmation sensor S2 (including the case where the card is slipped and not conveyed), Can be determined to have been continuously transported without interruption, and the motor 32 is stopped (step S26). In addition,
When the two cards are conveyed continuously without interruption, the set time of the timer T3 is set before the time when the second card passes the confirmation sensor S1.

Simultaneously with the stop of the motor, the card is immediately stopped, and the timer T6 is operated (step S27), and it is determined whether the light blocking of the confirmation sensor S2 is completed, that is, whether the confirmation sensor S2 emits light. (Step S28). If the confirmation sensor S2 emits light (YES), it is determined whether the confirmation sensor S1 emits light (step S2).
9) When the confirmation sensor S1 emits light (in the case of YES)
Is terminated at a position where the user can pull out one card, and it can be determined that the user has pulled out the card within the time of the timer T6, thus ending the normal operation (step S13). When the confirmation sensor S1 does not emit light (in the case of NO), two cards are conveyed continuously and the first card is clogged at a position where the user can remove the card. Within 2 hours
Since the first card is in a position where the user can not remove it,
The motor is rotated in reverse for the time set by the timer T7. After the reverse rotation, it is determined whether or not the confirmation sensor S1 is projected (step S32). If the confirmation sensor S1 is projected (YE).
In the case of S), it is determined that the second card has returned to the stacker, and the normal operation ends (step S33). If the confirmation sensor S1 does not emit light (in the case of NO), the second card is clogged. It is determined that the release cannot be performed, and the apparatus is abnormally stopped (step S33).

If the confirmation sensor S2 does not emit light in the step S28 (NO), it is determined whether or not the timer T6 has passed the set time (step S30), and if not, (NO). Returns to the step before step S28, and if it has elapsed (in the case of YES), it is a blockage in a state where the confirmation sensor S1 and the confirmation sensor S2 are shielded from light, and a blockage or a blockage occurs in a place where the user cannot remove it. It is determined that the user has forgotten to take the card, and the apparatus is abnormally stopped (step S33).

In the above description, the set time of the timer T2 is
Based on the time during which the feeding roller makes one rotation, the value is smaller than the value obtained by subtracting the set time of the timer T3 from this value.
That is, this is the time when the next card does not reach the confirmation sensor S1. The set time of the timer T3 is determined based on the transport time per 1 mm obtained from the feeding speed of the feeding roller and the feeding roller and the length of the card. This is a time during which at least the second card does not reach the confirmation sensor S2.

The positional relationship between the rollers 21 and 27 and the confirmation sensors S1 and S2 will be described with reference to FIG. Stacker 1

As described above, according to the present invention, the sending speed of the second roller is set to be higher than the feeding speed of the first roller. Thus, even when there is a card after being fed by the first roller, an interval can be generated between the preceding card and the following card, and continuous feeding of two cards can be prevented.

Further, a first detection sensor for detecting a card fed from the feeding port of the stacker and a second detection sensor for detecting a card sent out are provided, and the first detection sensor and the second detection sensor are provided. When the sensor detects a fed-out or fed-out card, the card is clogged, including the one caused by continuous feeding of two cards, depending on the detection, non-detection, order, transition time to the next step, etc. Is detected and, for example, by reversing the drive source, it is possible to deal with clogging of the card and prevent it.

Further, when the first roller and the second roller are driven by one driving device and the first roller and the second roller contact one card at the same time, the sending output is repeated. If the configuration is made so as to give priority to the output, the size and cost of the apparatus can be reduced.
