FIG. 4A is a front view of the width-adjustment feed roller, and FIG. 4B is a side view of the width-adjustment feed roller. Reference numeral 35 denotes a rubber chip provided on the width-adjusting feed roller 14. The rubber chip 35 is provided at two opposite positions on the circumferential surface of the width-adjusting feed roller 14,
The rubber portion is provided so as to protrude from the circumferential surface of the width-adjusting feed roller 14. Since the feed roller 14 is made of a material having a low friction coefficient, the circumferential surface of the feed roller 14 has a low friction coefficient. On the other hand, the rubber chip 35 has a high coefficient of friction with respect to the width adjusting feed roller 14. Therefore, when the width-adjusting feed roller 14 rotates while the medium is pressed against the width-adjusting feed roller 14 by the width-adjusting pressure roller 15, a conveying force is mainly generated at the rubber chip 35.

Numerals 36 are tapered portions formed at both ends of the circumferential surface of the width-adjusting feed roller 14. As described with reference to FIG. 1, the width-adjusting feed roller 14 faces in a direction orthogonal to the medium transport direction. For this reason, the taper portions 36 are provided at both ends of the circumferential surface of the width-adjusting feed roller 14 so that the end of the medium is not caught by the width-adjusting feed roller 14 when the medium is conveyed by the conveyance feed roller 10. .

FIG. 5 is an explanatory diagram showing the relationship between the width adjusting feed roller and the upper surface guide. Width feed roller 1
Numeral 4 is always in a state of protruding from the guide surface of the upper surface guide 12, and the height from the guide surface of the upper surface guide 12 to the portion of the circumferential surface of the feed roller 14 where the rubber chip 35 is not provided is equal to the upper surface. The height from the guide surface of the guide 12 to the circumferential surface of the feed roller 10 is the same.

When the medium is caught on the rubber chip 35 when the medium is conveyed by the conveyance feed roller 10 or when the medium is inserted or removed by the operator, the medium may be prevented from being conveyed or the medium may be soiled. Therefore, it is necessary to create a state in which the rubber chip 35 is retracted. For this reason, the feed roller 1
The rubber chips 35 are provided at two opposing positions on the circumferential surface of No. 4, and the ratio of the rubber chips 35 to the circumferential length of the width-adjusting feed roller 14 is approximately 15 ° to 30 °, respectively. When the width adjustment feed roller 14 and the upper surface guide 12 are positioned within the range, when the width adjustment feed roller 14 is stopped in a state where the rubber chip 35 is horizontal, the rubber chip 35 The rubber chip 35 is set in a retracted state so as not to protrude from the guide surface of the guide 12.

When the width adjusting feed roller 14 is in a state where the rubber chip 35 is horizontal, the home position of the width adjusting feed roller 14 is set. 14 is stopped at this home position.
That is, when the medium is caught by the rubber chip 35 when the medium is conveyed by the conveyance feed roller 10 or when the medium is inserted or removed by the operator, the conveyance of the medium may be hindered or the medium may be stained. Except during the width adjustment operation by the width adjustment feed roller 14, the width adjustment feed roller 14 is stopped at this home position so that the rubber chip 35 does not protrude from the guide surface of the upper surface guide 12. As described above, the width-adjusting feed roller 14 is used for the rubber chip 3.
Parts other than 5 are made of a material having a low coefficient of friction.
The shape is provided with tapered portions on both side ends of the circumferential surface, so that if the width-adjusting feed roller 14 is set at the home position, the medium is conveyed by the conveyance feed roller 10 or when the medium is inserted or removed by the operator. , Does not hinder its operation.

By providing the rubber chip 35 on the width-adjusting feed roller 14, during the width-adjusting operation by the width-adjusting feed roller 14, when the rubber chip 35 contacts the medium, a necessary and sufficient conveying force is provided. Occurs and the media can be moved. The number of rubber chips 35 is not limited to two, but when three or more rubber chips 35 are provided, in order to create a state in which the rubber chips 35 are retracted, the stop position accuracy of the width adjustment feed roller 14 and the width adjustment feed It is necessary to improve the accuracy of the amount of protrusion of the roller 14 from the guide surface of the upper surface guide 12 and the amount of protrusion of the rubber chip 35 from the circumferential surface of the feed roller 14 to increase the cost. In addition, by providing the rubber chip 35 at two opposing positions on the circumferential surface of the width-adjusting feed roller 14, the rubber chip 35 can be brought into contact with the medium twice evenly during one rotation of the width-adjustment feed roller 14. As a result, the medium can be moved in a short time, and a thin medium does not generate an excessive transport force. in this way,
The rubber chips 35 are desirably provided at two opposing positions on the circumferential surface of the width-adjusting feed roller 14.

Is detected. When the sensor 39 detects the wing portion 38, the width adjusting feed roller 14 and the slit disk 37 are in a positional relationship such that the width adjusting feed roller 14 becomes the home position. When the feed roller 14 is stopped, the sensor 39
When the wing portion 38 detects the wing portion 38, the rotation of the width adjusting feed roller 14 is stopped, so that the width adjusting feed roller 14 stops at the home position. Since the rubber chips 35 are provided at two opposing positions on the circumferential surface, two slit disks 37 are also provided at the positions where the wings 38 oppose each other. Even when the width adjustment feed roller 14 is detected, the width adjustment feed roller 14 is at the home position, and there is a timing at which the home position can be detected twice while the width adjustment feed roller 14 rotates once.
When it is necessary to stop the rotating feed roller 14 that is rotating, the feed roller 14
Can be stopped at the home position without rotating.

2 is attached to the support shaft 41. One end of the arm 42 is rotatably attached to the support shaft 41, and can operate independently of the leaf spring 40 synchronized with the rotation of the support shaft 41. Therefore, the conveyance pressure roller 11 and the width adjustment pressure roller 15 can independently switch between contact and non-contact with the medium.

The pressure roller 15 is attached to the arm 42 via a bracket assembly 43. 8A and 8B are explanatory views of the bracket assembly. FIG. 8A shows a state where a thin medium is pressed against the feed roller 14 and FIG. 8B shows a state where a thick medium is pressed against the feed roller 14.

When two sets of the transport pressure rollers 11 are provided in the transport direction as in the passbook stage 3 described with reference to FIG. 3, the DC motor 54 is used in common.
A mechanism for transmitting the driving force of the C motor 54 is provided so that the two sets of transport pressure rollers can be moved up and down in synchronization. Next, a driving mechanism of the transport feed roller and the width feed roller will be described. FIG. 12 is an explanatory diagram showing a driving force switching mechanism.

It is connected to the feed roller 10 via a shaft, a gear train, or the like. Reference numeral 61 denotes a width shifting gear, and the width shifting gear 61 is connected to the width shifting feed roller 14 via a shaft, a gear train, or the like. Reference numeral 62 denotes a slide gear which slides along a guide shaft 63 and engages with either the transport gear 60 or the width shifting gear 61. The slide gear 62 has a width indicated by a solid line in FIG. It engages with the shift gear 61 or engages with the transport gear 60 at the position shown by the broken line in FIG.

Reference numeral 8 denotes a driving force switching cam.
8 is attached to the switching shaft 53. The driving force switching cam 68 is a cam provided with a slope on a side surface. The arm 69 has one end in contact with the slope of the driving force switching cam 68 and the other end in the slide gear 6.
2 is connected to the slide gear 62 in a movable and rotatable state. The arm 69 is rotatable about a shaft 70, and one end of the arm 69 is always in contact with the driving force switching cam 68 by a spring 71. As a result, the driving force switching cam 68 rotates, so that one end of the arm 69 has one end.
And the shaft 70 rotates about the fulcrum. Then, the slide gear 62 is moved by the other end of the arm 69, and the slide gear 62 meshes with the transport gear 60 or the width shifting gear 61. Thus, the driving force from the pulse motor 67 can be switched so as to be transmitted to either the transport feed roller 10 or the width-adjusting feed roller 14. Can be shared. The width feed roller 14 and the transport feed roller 1
Since 0 is different in the direction of the rotating shaft, a bevel gear is inserted in the transmission path of the driving force.

As described above, the driving force switching cam 68 is fixed to the switching shaft 53. Since the first cam 51 and the second cam 52 are attached to the switching shaft 53 as described above, the vertical movement of the transport pressure roller 11 and the width adjusting pressure roller 15 and the width of the transport feed roller 10 Switching of the driving force of the shift feed roller 14 is linked, and this can be performed by one driving source, here, the DC motor 54.

The relationship between the vertical movement of the transport pressure roller and the width adjusting pressure roller and the switching of the driving force of the transport feed roller and the width adjusting feed roller will be described below. The transport P is performed by the first cam and the second cam.
In the OFF / width shift POFF state, the slide gear 62

In the transport POFF / width-adjustment PON state, the slide gear 62 is moved to a position where it engages with the width-adjustment gear 61 by the driving force switching cam 68. In the transport POFF / width-adjustment PON state, the slide gear 62 is driven toward the width-adjustment feed roller 14 side. Power is transmitted.

In the transport PON / width-adjusting PON state, neither the transport feed roller 10 nor the width-adjusting feed roller 14 is driven. The stage is switched to the shifting gear 61 or the stage is switched from the shifting gear 61 to the transport gear 60.

Next, a control system of the passbook slip printer according to the present embodiment will be described. FIG. 13 is a control block diagram of the passbook slip printer. It should be noted that the control blocks shown in FIG. 13 focus on the control blocks of the inserter unit. Reference numeral 80 denotes a main control unit, which controls the inserter unit 5, the printing unit 6, and the ATP unit 7 described with reference to FIG. The details of the printing unit 6 and the ATP unit 7 are not shown here.

In the inserter unit 5, the main controller 80 includes, on the passbook stage 3, right width detection sensors 32 a and 32 b, left width detection sensors 33 a and 33 b,

In the following description, the passbook stage 3 will be described as an example, but the same operation is performed on the slip stage 2 as well. In FIG. 1, the medium (passbook) is placed on the right reference plane 3.
An example will be described in which the process is performed in a state where the process hits 0.
When the operator sets the medium on the passbook stage 3, the main control unit 80 sets the inhalation detection sensors 34a and 34b
Is detected, it is determined that the medium has been set. In addition, two inhalation detection sensors were provided.
This is to prevent a malfunction by detecting a finger or the like when there is only one inhalation detection sensor.

When determining that the medium has been set, the main control unit 80 monitors the outputs of the right width shift detection sensors 32a and 32b, and determines whether the medium has hit the right reference plane 30. The main control unit 80 includes a right width shift detection sensor 32a,
If both of them are ON, it is determined that the medium is abutted against the right reference plane 30. The reason why the two width shift detection sensors are provided in the transport direction is to enable detection of skew. If the width shift detection sensors before and after the transport direction are ON, the medium is positioned straight on the reference surface. It is struck and it is determined that the position is correct.

When it is determined that the medium is abutted against the right reference plane 30, the main control unit 80 monitors the output of the sensor 57 and detects the slit 56e.
From the number of detections 6a to 56d, the conveyance POFF / width adjustment PO
The DC motor 54 is rotated from the state of the FF to the state of the conveyance PON / width shift POFF. When the main control unit 80 determines from the output of the sensor 57 that the state is the conveyance PON / width adjustment POFF state, the main motor 80 stops the DC motor 54. In the transport PON / width shift POFF state, the medium is transported by the transport pressure roller 11 to the transport feed roller 10.
, And the slide gear 62 is
The driving force of the pulse motor 67 is transmitted to the feed roller 10 side.

Next, the main control unit 80 rotates the pulse motor 67 in the normal direction, rotates the transport feed roller 10 in the take-in direction, takes in the medium, and sends it to the printing unit 6 at the subsequent stage. In addition, the transport PON / width shift POF at the time of media transport
In the state F, the width adjusting pressure roller 15 is retracted from the guide surface of the lower surface guide 13, and the medium is not pressed against the width adjusting feed roller 14. Also, as described with reference to FIG. 5, except for the time of the width shifting operation, the rubber tip 35 is used for the width shifting feed roller 14.
Since the rubber chip 35 is stopped at the position retracted from the guide surface of No. 2, the rubber chip 35 does not come into contact with the medium at the time of conveyance and does not hinder the conveyance.

When the main control unit 80 determines that the medium has been set, if at least one of the right width shift detection sensors 32a and 32b is OFF, the sensor 5
While monitoring the output of No. 7, the DC motor 54 is rotated until the state of transport POFF / width shift PON is reached. The main control unit 80 determines the conveyance POFF / width adjustment P from the output of the sensor 57.
If it is determined that the state is ON, the DC motor 54 is stopped. In the state of conveyance POFF / width adjustment PON, the medium is pressed against the width adjustment feed roller 14 by the width adjustment pressure roller 15, and the slide gear 62 moves and meshes with the width adjustment gear 61, and the pulse motor 67 is moved.

The slide gear 62 meshes with the width adjustment gear 61, and the driving force of the pulse motor 67 is transmitted to the width adjustment feed roller 14 side. It is moved in the direction of the surface 30. As described with reference to FIG. 4, the width-adjusting feed roller 14 is provided with the rubber chips 35 at two opposing positions on the circumferential surface. Occurs and moves the media. Then, the main control unit 80 controls the right width shift detection sensor 32
When both a and 32b are ON, when the wing portion 38 is detected a plurality of times from the output of the sensor 39, here twice,
The drive of the pulse motor 67 is stopped at the time of the second detection.
When the pulse motor 67 is stopped, the sensor 39
Is detected, the feed roller 14 is adjusted as shown in FIG.
Stop at the home position shown in.

As described above, after both of the right width shift detection sensors 32a and 32b are turned on during the width shift operation, the sensor 39 detects the wing portion 38 a plurality of times, for example, twice. As the rotation continues, the rubber chip 35 comes into contact with the medium at least once. This allows
Even if the medium has a large thickness, it can reliably hit the right reference plane 30. When the medium is a thin one such as a slip, the feeding roller 14 has a small conveying force except for the rubber chip 35, so that the medium is not damaged.

Next, the main control unit 80 rotates the DC motor 54 while monitoring the output of the sensor 57 until the state of PON / conveyance POFF is reached. Main control unit 80
When it is determined from the output of the sensor 57 that the state is the conveyance PON / width shift POFF state, the DC motor 54 is stopped. In the transport PON / width shift POFF state, the medium is transported by the transport pressure roller 11 to the transport feed roller 10.
, And the slide gear 62 is
The driving force of the pulse motor 67 is transmitted to the feed roller 10 side.

Next, the main controller 80 rotates the pulse motor 67 in the normal direction, rotates the feed roller 10 in the take-in direction, takes in the medium, and sends it to the printing unit 6 in the subsequent stage. After sending the medium to the printing unit 6, the main controller 80 controls the transport PO in the inserter unit 5.
While the state of N / width shift POFF is maintained, when discharging the medium, the pulse motor 67 is rotated in the reverse direction to discharge the medium. When the main control unit 80 determines that the medium has been conveyed to the predetermined position, the main control unit 80 monitors the output of the sensor 57 while conveying the medium.
DC motor 5 until FF / width shift POFF
Rotate 4. When the main control unit 80 determines from the output of the sensor 57 that the state is the conveyance POFF / width adjustment POFF state, the main motor 80 stops the DC motor 54. As described above, by setting the conveyance POFF / width adjustment POFF, the medium is not pressed against the feed roller by any of the pressure rollers, and the operator can extract the medium.

In the above description of the operation, the operation of abutting the medium on the right reference plane 30 has been described.
1, the main control unit 80 monitors the outputs of the left-side shift detection sensors 33 a and 33 b, and if the medium needs to be shifted, changes the rotation direction of the width-adjustment feed roller 14 to the left. The same is true except that the direction of conveyance is in the direction of the reference surface 31.

[0070]

As described above, the present invention includes a width-adjusting feed roller that conveys a medium set on a stage in a reference plane direction, and a width-adjusting pressure roller that presses the medium against the width-adjusting feed roller. Since the rollers are used to adjust the width of the medium by abutting the medium against the reference surface, a mechanism for the width adjustment operation can be installed in a small space, and the inserter unit can be reduced in size.

Further, the transport pressure roller has a first shape for moving the medium to a position where the medium is pressed against the feed roller and a shape for moving the medium to a position where the medium is retracted from the stage.
And a second cam having a shape for moving the width adjusting pressure roller to a position where the medium is pressed against the width adjusting feed roller and a shape for moving the medium to a position where the medium is retracted from the stage. A driving force transmitting means for transmitting a driving force between the cams, and a driving means for applying a driving force to the driving force transmitting means. It can be realized with one drive source, and the inserter section can be downsized.

Further, a transport drive means for driving the transport feed roller and the width feed roller, and a driving force for switching the transmission path of the driving force from the transport drive means to either the transport feed roller or the width feed roller. A driving force switching cam for operating the driving force switching means, wherein the driving force switching cam transmits the driving force between the first cam and the second cam; And the driving means receives the driving force, so that a single driving source can selectively drive the conveyance feed roller and the width-adjustment feed roller, and the switching of the driving force transmission path is performed by the conveyance pressure. Since the drive source is used in common with a drive source for vertically moving the roller and vertically moving the width approach pressure roller, the inserter unit can be downsized.

As described above, by reducing the size of the inserter unit, it is possible to reduce the size of the entire medium processing apparatus. Further, in performing the width shifting operation with the roller, the width shifting feed roller is provided with a high friction member that generates a force for conveying the medium on a part of the circumferential surface, and the other circumferential surface is formed of a low friction member. By doing so, it is possible to prevent an excessively strong transport force from being generated when narrowing a thin medium, and to generate a sufficient transport force when narrowing a thick medium, whereby reliable width adjustment can be performed.

Further, a position managing means for managing the position of the high friction member is provided, and when the width adjusting feed roller is stopped, it is stopped when the high friction member is retracted to a position where it does not come into contact with the medium. The high-friction member of the width-adjusting feed roller does not hinder the operation of the medium when the medium is transported or when the operator sets or removes the medium.
