DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a form processing device.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional passbook / slip printer as an example of a conventional form processing apparatus. In this conventional example, a passbook / slip printer includes a passbook transport path 4A and a slip transport path 4B.
And a processing transport path 8 extending from a confluence with the passbook transport path 4A and the slip transport path 4B. A printing section 7 is disposed at the end of the processing transport path 8. The passbook inserted from the passbook insertion slot 10 is delivered to the pair of transport rollers 11 of the processing transport path 8 by the pair of transport rollers 11 arranged in the passbook transport path 4A, and then subjected to necessary processing in the printing unit 7, and The paper is discharged from the passbook insertion slot 10 through the route.

On the other hand, a slip inserted into the slip insertion slot 12 is transferred to a pair of transport rollers 11 in a processing transport path 8 by a pair of transport rollers 11 in a slip transport path 4B, and then required processing is performed in a printing unit 7. The document is discharged from the slip insertion port 12 through the same route.

However, in the above-described conventional example, the transport roller pairs 11 of the passbook transport path 4A and the slip transport path 4B are driven by separate drive motors 5, so that the number of drive motors 5 is increased and the apparatus is increased. There is a problem that the size is increased and the cost is increased. In FIG. 5, arrows indicate the correspondence between each pair of transport rollers 11 and the drive motor 5 for driving the pair of transport rollers 11.

In order to solve this problem, as shown in FIG. 6, a pair of transport rollers 11 of a passbook transport path 4A and a slip transport path 4B are driven by the same drive motor 5. That is, in this conventional example, the passbook transport path 4A
And the transport roller pair 11 of the slip transport path 4B include a drive roller 2 fixed to the drive gear 1, and one of the drive gears 1 is selected by the selection gear 6. A selection gear 6 to which the driving force of the drive motor 5 is transmitted via a timing belt (not shown) is supported by a swing lever 14 that can swing around a support shaft 13, and the selection gear 6 swings the swing lever 14. The driving operation causes the drive roller 2 to be meshed with one of the drive gears 1 and connected to the drive gear 1 to be driven.

However, in this conventional example, the selection gear 6
When the gear is rocked to mesh with one of the drive gears 1, the selection gear 6 cannot rotate idle and the load of the drive roller 2 is applied to the drive gear 1. As a result, wear and damage of the cutting edge are likely to occur. In addition, at the time of meshing, the drive gear 1 side has room to rotate by a maximum of one pitch against the resistance force in the rotation direction, but the rotation direction is determined by the positional relationship of the tooth tips and is not determined uniquely. . For this reason, as shown in FIG. 7, for example, when the slip 3A is held in the slip transport path 4B and the presence of the slip 3A is detected by the sensor 15, the slip transport path is When the drive gear 1 of 4B rotates toward the slip-drawing side (direction A in the drawing), the sensor 15 senses slip-drawing and stops the apparatus.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned drawbacks, and is intended to reduce the size and cost of the apparatus by sharing a drive motor, and to further improve the operation reliability of the form. It is intended to provide a processing device and a passbook / slip printer.

[0008]

According to the present invention, the above object is achieved by a plurality of medium transport paths 4 which are arranged adjacent to each other and are capable of transporting a medium 3 in a predetermined direction by a drive roller 2 driven by a drive gear 1. A selection gear that is rotatably driven by a drive motor 5 between drive gears 1 of each medium transport path 4 and meshes with one of the drive gears 1 so that a meshing partner can be changed. 6 is disposed, and the selection gear 6 is a form processing device that moves to a meshing position at an approach angle at which a component force in a predetermined rotational direction is applied to the drive gear 1 when the tip circles contact the drive gear 1. Achieved by providing.

The form processing apparatus has a plurality of medium transport paths 4, and a drive roller 2 to which a drive gear 1 is fixed is disposed in each medium transport path 4. The driving roller 2 is a driven roller 16
Along with this, a pair of transport rollers 11 is formed to transport the medium 3 in a predetermined direction in the medium transport path 4 while sandwiching the medium 3. Selection gear 6
Can selectively mesh with one of the plurality of drive gears 1, and applies the driving force of the drive motor 5 to only the selected drive gear 1.

Although various means such as a slide means can be employed for driving the selection gear 6, the operation of the present invention will be described with an example in which a swing lever 14 is used. As shown in FIG. 1, the swing lever 14 is rotatable about a swing center 17, and the selection gear 6 rotatably supported at the tip of the swing lever 14 is provided with a power such as a timing belt 18. The transmission unit transmits the rotational power of the drive motor 5.
In FIG. 1, the selection gear 6 and the driving gear 1 are indicated by tooth tips, and the two driving gears 1 and 1 indicate the driving gears 1 on different medium transport paths 4.

In FIG. 1, meshing with the driving gear 1 shown on the right side (for example, the driving gear 1A on the passbook conveying path side) is released, and meshing with the driving gear 1 shown on the left side (for example, the driving gear 1B on the slip conveying path side). The selection gear 6 moves from the passbook transport path 4A to the drive gear 1B on the slip transport path 4B along a swing locus L indicated by a chain line. Now, assuming that the addendum circle diameters of the drive gear 1B and the selection gear 6 are the same, the locus L 'in FIG. 1A is the swing locus of the select gear 6 of the conventional example, and The common normal H at the time of contact passes through the rotation center of the drive gear 1B. In this state (hereinafter referred to as the “neutral position”), no rotational force is applied to the drive gear 1, so that the rotational direction of the drive gear 1 </ b> B at the time of meshing is fluctuated until the pitch circles contact each other. It is determined only by the positional relationship of the teeth when moving, and cannot be predicted in advance.

On the other hand, in the present invention in which the selection gear 6 moves along the locus L, the contact point P between the addendum circles of the selection gear 6 and the drive gear 1 is clockwise from the neutral position in the illustrated example. And the instantaneous approach direction line of the contact point (perpendicular line drawn from the contact point P with respect to the line segment connecting the contact point P and the swing center 17) and the rotation center of the drive gear 1 on the slip conveyance path 4B side. An interval δ is formed between them. On the other hand, since the drive motor 5 is connected to the selection gear 6 and idling is prohibited, a rotational force is applied to the drive gear 1 by the instantaneous approach direction line and the interval δ. Since the magnitude of the rotational force varies depending on the posture of the teeth when the teeth mesh with each other, the magnitude of the rotational force is not constant, but the rotational direction is uniquely determined, and in the illustrated example, the rotational direction is clockwise.

Therefore, in the present invention, as shown in FIG. 2, different medium transport paths 4, 4 can be switched and driven by the same drive motor 5, so that the apparatus can be downsized.
Cost reduction is achieved. The direction of rotation of the drive gear 1 that is the meshing partner of the selection gear 6 is determined by the contact point P
Is uniquely determined in the direction deviated from the neutral position, so that the fine movement direction of the medium 3 held by the drive gear 1 in the corresponding transport path can be predicted. Therefore, FIG.
As shown in (a), when the sensor 15 detects the leading end of the medium 3, the medium 3 reliably moves only in the direction of the arrow and does not move in the opposite direction. No longer sends out the medium 3 extraction signal,
Operational reliability is improved.

The form processing apparatus is a passbook / slip printer in which a passbook transport path 4A and a slip transport path 4B are connected to a processing transport path 8 having a printing unit 7 near the end thereof. A selection gear 6 that oscillates between the driving gears 1A and 1B for driving the driving roller 2A and the driving roller 2B of the slip conveyance path 4B, respectively, and meshes with one of the driving gears 1;
A drive motor 5 for driving the selection gear 6, wherein the selection gear 6 is brought into a meshing position at an approach angle at which a component force in a predetermined rotation direction is applied to the drive gear 1 when the drive gear 1 and the addendum circle contact each other. A moving passbook / slip printer can be configured.

In this case, as shown in FIG. 1B, a stopper ring 9 concentric with the addendum circle is provided on the selection gear 6 and the drive gear 1.
Are provided, and the stopper rings 9 are brought into contact with each other to regulate the biting depth of the teeth. The control of the biting depth of the teeth can be performed by controlling the swing angle of the swing lever 14, but the use of the concentric stopper ring 9 for the drive gear 1 reduces errors.

[0016]

FIG. 2 shows an embodiment of the present invention configured as a passbook / slip printer. The passbook / slip printer is provided with a passbook transport path 4A and a slip transport path 4B adjacent to each other.
Linked to In each medium transport path 4, a plurality of transport roller pairs 11 including a drive roller 2 and a driven roller 16 are arranged.

A passbook insertion slot 10 is formed by opening the start end of the passbook transport path 4A to the front wall of the housing 19. When the passbook is inserted into the passbook insertion slot 10, after the insertion of the slip is confirmed by the sensor 15 described later, the passbook is transported to the terminal side,
The image is transferred to the processing transport path 8 and printed by the printing unit 7 disposed at the end of the processing transport path 8. The printed passbook is conveyed in the reverse direction, and is again returned from the passbook insertion slot 10 to the housing 19.
It is discharged outside.

The slip transport path 4B has a leading end opening at the front wall of the housing 19 to form a slip insertion port 12, and the end is connected to the junction of the passbook transport path 4A and the processing transport path 8. Also,
A sensor 15 for confirming that the slip is being supplied to the slip transport path 4B is arranged near the end of the slip transport path 4B. The slip inserted into the slip insertion slot 12 is
After confirming the end of the passbook printing process, the transported roller pair 11 transports the document to the processing transport path 8 side, and the printed slip is discharged from the slip insertion slot 12 in the reverse direction.

A method of driving each medium transport path 4 will be described. First, the plurality of drive rollers 2 arranged in the processing transfer path 8 are fixed to the drive shaft 2a, respectively, and the medium 3 can be transferred in the forward and reverse directions by rotating the drive shaft 2a. The drive shaft 2a is driven by one drive motor 5, and a drive belt 5 or a timing belt (not shown) is used to transmit the drive force. In FIG. 2, the driving roller 2 to which the rotational force is transmitted by the driving motor 5 is indicated by a broken arrow from the driving motor 5.

On the other hand, the passbook transport path 4A and the slip transport path 4B are driven by the same drive motor 5. A part of the drive rollers 2 of the passbook transport path 4A and the slip transport path 4B is driven by being transmitted with power from a drive motor 5 by a timing belt or the like in the same manner as the processing transport path 8 described above, and is partially switched.
0 is driven.

The switching unit 20 supplies the medium 3 (hereinafter, referred to as both “passbook” or “slip” or simply “medium” when referring to one that is not specified) to the printing unit 7 by passing the passbook transport path 4A or The transfer is performed from one of the slip transport paths 4B, and the two medium transport paths 4 (hereinafter referred to as passbook transport paths 4B).
A or both the slip transport path 4B and one not specified are simply referred to as “medium transport path”. ) Need not be driven at the same time, and is provided by reciprocating between the drive gears 1A and 1B provided on the passbook transport path 4A and the slip transport path 4B, and between the drive gears 1A and 1B. And a selection gear 6 for transmitting a driving force to the selected one of the driving gears 1.

In this embodiment, the passbook transport path 4A
The drive gear 1A on the side is directly fixed to the drive shaft 2a, while the drive gear 1B on the slip transport path 4B meshes with the relay gear 21 fixed on the drive shaft 2a, and the rotation direction of the drive shaft 2a is changed. It matches the feed direction of the other drive rollers 2 on the slip transport path 4B. In this manner, by interposing an appropriate gear train between the drive shaft 2a of the medium transport path 4 to be switched and the selection gear 6, the rotation direction of the transport roller pair 11 can be adjusted. Since the drive gears 1 can be arranged close to each other, the length of the movement path of the selection gear 6 can be shortened, and the reliability is improved.

The selection gear 6 is rotatably mounted on the tip of a swing lever 14 rotatable about a swing center 17, and is driven to rotate by power transmitted from the drive motor 5.

As described above in detail, the selection gear 6 moves along a rocking trajectory L in which a rotational component in a certain direction is generated in a state where the tip circle is in contact with the driving gear 1 to be meshed. I do. In this embodiment, the addendum circle of the selection gear 6 comes into contact with the addendum circle of the drive gear 1B on the slip conveyance path 4B side at a position shifted clockwise from the neutral position.
At the time of meshing, the driving gear 1B rotates clockwise, and the relay gear 21 meshing with the driving gear 1B is driven counterclockwise. As a result, the slip captured by the slip transport path 4B surely slightly moves to the terminal side, so that it does not come off the slip detection sensor 15, and the slip extracting signal is not issued unnecessarily.

FIGS. 3 and 4 show details of the switching unit 20. FIG.
The swing lever 14 includes an operation portion 14a extending from the swing center 17 in a direction opposite to the pivot portion of the selection gear 6. A relay pulley 22 is pivotally mounted on the swing center 17, and the power from the drive motor 5 is transmitted to the relay pulley 22 via a timing belt 18 '.
8 to the selection gear 6. In FIG. 4, reference numeral 23 denotes a transmission pulley fixed coaxially with the selection gear 6 and around which the timing belt 18 is wound.

The operating portion 14a is connected to a plunger magnet 25 via a tension spring 24, and the swing lever 14 is driven by driving the plunger magnet 25.
Can be rotated to engage the selection gear 6 with the drive gear 1. Further, the selection gear 6 and the driving gears 1A, 1
A cylindrical stopper ring 9 is coaxially mounted on the gear B and is freely rotatable. The stopper ring 9 is in a state where the selection gear 6 is meshed with the drive gear 1,
That is, the pitch circles come into contact with each other in a state where they are in contact with each other, and the engagement depth is regulated.

Further, in this embodiment, the switching section 20 includes a pair of stopper racks 26 corresponding to the driving gear 1. The stopper rack 26 is formed at the tip of a pair of stopper levers 27 rotatable about the same axis as the swing lever 14, and the ends of the stopper lever 27 are connected by a tension spring 28. Stopper lever 27
The swing lever 14 swings so that the stopper rack 26 meshes with the drive gear 1 on the opposite side to the drive gear 1 on the side where the selection gear 6 meshes (in the illustrated example, the drive gear 1A on the passbook transport path 4A side). The drive gear is driven in synchronization with the moving operation, and the rotation of the opposite drive gear is prohibited by the stopper rack 26.

Therefore, in this embodiment, at the start of work, the selection gear 6 is driven by the drive gear 1 on the slip transport path 4B.
When B is selected and a passbook is inserted from the passbook insertion slot 10 and a slip is inserted from the slip insertion slot 12, the slip is transported in the slip transport path 4B and stopped until the sensor 15 detects the tip of the slip. Thereafter, the selection gear 6 passes through the passbook transport path 4A.
The passbook is switched to the side, and the passbook is sent out to the processing conveyance path 8, and after the printing section 7 performs the printing process, it is sent back to the passbook conveyance path 4A again. Next, the selection gear 6 is switched to the slip transport path 4B, and after confirming the presence of the slip in the slip transport path 4B, the slip is printed and discharged from the slip insertion port 12, and then the passbook transport path 4A. The passbook that has been waiting in the bank is updated with magnetic stripe information and the like, and the passbook is discharged from the passbook insertion slot 10.

Although the form processing apparatus has been described above by taking a passbook / slip printer as an example, the present invention can be configured as various other form processing apparatuses.

[0030]

As is apparent from the above description, according to the present invention, since the drive motor can be shared by different medium transport paths, the size and cost of the apparatus can be reduced. In addition, since the fine movement direction of the transport roller can be set in advance when the drive of the medium transport path is switched,
Operation reliability can be improved.
