Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a width-adjusting mechanism used in a financial terminal, a general-purpose printer, or the like, and more specifically, a width-adjusting roller is used to push a medium on a conveying path to a side portion of the conveying path. The present invention relates to a width-shifting mechanism that contacts a contact member and positions a medium at a reference position in the width direction.

[0002]

2. Description of the Related Art In recent years, computer banking systems have been rapidly developed, and at financial institutions, a bankbook processing (printing) device operated by a teller at a counter or an ATM (automatic deposit payment machine) operated directly by a customer. Etc. are often used. In this device, a medium such as a passbook inserted in the device is brought into contact with an abutting member arranged on the side portion of the conveyance path by a width-adjusting roller to set the medium at a reference position in the width direction. A positioning mechanism for positioning is incorporated.

A magnetic stripe (M) on the passbook inserted in the insertion port is provided in the conveyance path in the width-shifting mechanism of the passbook processing device or the like.
Various parts such as a part of the MS unit for reading or recording S) and a part of the conveying roller of the width-shifting mechanism are projected, and the conveying path has irregularities especially in the ceiling part. Therefore, particularly in a thick medium such as a passbook, the medium may come into contact with the uneven portion of the transport path.

[0004]

In this type of width-adjusting mechanism, when the media is width-adjusted, the width-adjusting roller is lowered, the medium is pressed downward, and then the width-adjusting roller is rotated to move the medium. Is moved in the width direction and brought into contact with the abutting member.

At this time, if the medium is thin, the medium and the uneven portion of the transport path do not come into contact with each other when the medium is pressed downward by the width-shifting roller. However, with closed passbooks and thick media, even when the media is pressed downward with the width-shifting roller,
The contact between the medium and the uneven portion of the transport path may not be eliminated, and a large driving force may be required for sliding the medium in the widthwise direction. At times, it may not be possible to perform width adjustment accurately.

Further, when the operator sets the medium, the abutting portion is too strongly abutted against the abutting member provided on the side portion of the conveying path, and the abutting portion is partially turned up (overabutting). In some cases, the medium cannot be positioned at the reference position in the width direction.

Therefore, the conventional mechanism has a problem that the medium cannot be stably positioned at the reference position in the width direction. The present invention has been made to solve the above problems, and an object thereof is to realize a width-shifting mechanism that can stably position a medium at a reference position in the width direction.

[0008]

According to a first aspect of the invention for solving the above-mentioned problems, the media on the conveying path is brought into contact with an abutting member arranged on a side portion of the conveying path by a width-shifting roller, In a width-shifting mechanism for positioning a medium at a reference position in the width direction, a drive for bringing the medium into contact with the abutting member is performed until the medium is brought into contact with the abutting member until a series of width-shifting sequences are executed and positioning of the medium is completed. It is characterized in that it is repeated a plurality of times with an opposite direction driving for separating from the abutting member interposed therebetween.

According to the present invention, the medium is vibrated in the width direction, and as a result, the sliding frictional force between the medium and its abutting surface is reduced, and the medium is smoothly slid in the width direction. Therefore, even in the case of over-butting, the over-butting state is resolved, and the medium can be easily moved to the reference position in the width direction. Therefore, the medium can be stably positioned at the reference position in the width direction (of course, the posture of the medium can be corrected).

According to a second aspect of the present invention, in the first aspect of the present invention, a pressure member is provided for pressing the medium on the conveying path in the thickness direction thereof and permitting the medium to move in the width direction in the pressed state. However, when the width-shifting roller is driven, the medium is pressed by the pressure member.

According to the present invention, since the pressure member presses the medium when the width-shifting roller is driven, the curvature of the medium is corrected during the positioning operation, and the flatness of the medium is maintained. Even if the medium is used, the medium does not strongly contact the uneven portion of the transport path, and the medium can be moved to the reference position in the width direction more stably.

According to a third aspect of the present invention, in the second aspect of the present invention, a pressure roller having a rotation center axis parallel to the traveling direction of the medium on the conveying path is provided at the contact portion with the medium as a pressure member. It is characterized by using a thing.

By providing the pressure member with the pressure roller, the flatness of the medium is maintained, and the sliding frictional force in the width direction of the medium is further reduced to facilitate the movement of the medium.
The medium can be positioned at the reference position in the width direction more stably.

A pair of fitting portions are coaxially formed on the pressure member at regular intervals, and the drive shaft, to which a carrying roller for carrying the medium is attached, is provided with the pair of fitting portions and the carrying roller. The pressure member can be easily attached by sandwiching it in the axial direction and rotatably fitting it. Further, in this case, since the pressure member can be arranged in the vicinity of the transport roller, which is the uneven portion of the transport path, the contact between the medium and the uneven portion of the transport path can be efficiently eliminated even with a closed passbook or a thick medium.

Further, a rotary shaft is arranged in parallel with a drive shaft, to which a transport roller for transporting the medium is attached, at a constant interval, a push arm is fixed to the rotary shaft, and the tip end portion is A width-shifting roller is rotatably attached to the tip of the swingable link that can be lowered, and the rotation of the rotation shaft is rotated by a certain angle to transmit the motion of the push arm to the swing link via the link mechanism. If the contact roller is pressed against the medium, the width roller can be easily moved up and down.

Further, if the pressure member is fitted to the drive shaft so as to be able to descend, and the base end of the elevating arm whose front end engages with the pressure member is fixed to the rotary shaft, the rotary shaft can be rotated at a fixed angle. By moving
The pressure member can be pressed against the medium in synchronization with the pressing of the width-shifting roller against the medium, which simplifies the configuration.

A driven arm protruding in the direction of the radius of rotation is provided at one end of the rotating shaft, and an output shaft of a solenoid having a constant stroke is connected to the tip of the driven arm so that the rotating shaft is rotated in the forward and reverse directions. By rotating it by a certain angle, the rotation range of the rotation shaft can be set accurately,
The lowered positions of the pressure member and the width-shifting roller can also be set accurately.

1 is a perspective view showing a main part of an embodiment of the present invention, and FIG. 2 is a plan view with a cover and the like attached.
In these figures, the medium 1 (see FIG. 2) is inserted into the insertion slot 2 by the operator.

The transport rollers 4, 5 for transporting the medium 1 inserted in the insertion slot 2 are fixed to the drive shaft 6, and the drive shaft 6 is driven by a transport motor (not shown) to rotate the transport rollers 4, 5. It is designed to let you.
A pinch roller (not shown) capable of pressing the medium 1 on the surface of each of the transport rollers 4 and 5 is arranged to face each of the transport rollers 4 and 5. The pinch roller conveys the medium 1 to the conveying rollers 4, 5
Pressed against the surface of the sheet (conveyor roller closed state)
At, the medium 1 can be transported by rotating the transport rollers 4 and 5.

On the drive shaft 6, pressure members 7 and 8 having the same shape and function are fitted so as to be able to descend. The pressure members 7 and 8 press the medium 1 on the transport path 3 in its thickness direction. The pressure member 7 (8) will be described in detail with reference to FIG.
The pressure member 7 (8) has a pressing roller 7 having a rotation center axis parallel to the traveling direction of the medium 1 on the transport path 3 in order to smoothly move the medium 1 in the width direction in the pressed state.
a, 7b (8a, 8b) are provided at the contact portion with the medium 1.

A pair of bifurcated arc-shaped fitting portions 7c, 7d (8c, 8d) are coaxially formed on the pressure member 7 (8) at regular intervals. The pair of fitting portions 7c, 7d (8c, 8d) are rotatably fitted to the drive shaft 6 so that they sandwich the conveyance roller 4 (5) from the axial direction.

The rotating shaft 10 is arranged in parallel with the drive shaft 6 at a constant interval, and a driven arm 11 projecting in the radial direction of rotation is provided at one end of the rotating shaft 10. The output shaft of the solenoid 12 is connected to the tip of the drive arm 11. The solenoid 12 has an output shaft that linearly reciprocates with a constant stroke, and the drive of the solenoid 12 can rotate the rotating shaft 10 in the forward and reverse directions.

As can be seen from the conceptual configuration diagram (the state in which the pressure members 7 and 8 and the width-adjusting roller 20 are lowered) viewed from the insertion port 2 side shown in FIG. 7 and FIG. An abutting member 15 to which the medium 1 on the transport path 3 is abutted is arranged in the. The width-shifting roller 20 feeds the medium 1 on the conveying path 3 to the abutting member 15 side and abuts against the abutting member 15 to position the medium 1 at a reference position in the width direction.

The width-shifting roller 20 and the pressure member 7,
When the width-shifting roller 20 is driven, the reference numeral 8 is both in the lowered position, and is raised and lowered in synchronization. Therefore, the rotating shaft 10 has a pushing arm 31 for transmitting the rotation of the rotating shaft 10 to the width-shifting roller 20 side, and the rotation of the rotating shaft 10 for transmitting the rotation of the rotating shaft 10 to the pressure members 7 and 8. And an elevating arm 32 for fixing.

In particular, as shown in FIG. 6, the pushing arm 31 is
Is for pushing the one end of the passive link 35 whose middle portion is rotatably supported by its tip. The other end of the passive link 35 is connected to the base end of an L-shaped swing link 37 via an intermediate link 36. This L
The swinging link 37 having a character shape rotates about a corner, and like the passive link 35 and the intermediate link 36, constitutes one link of a four-bar rotary chain.

The width-shift roller 20 is rotatably supported at the tip of the swing link 37, and the rotary shaft 10 is shown in FIG.
When rotated in the clockwise direction (arrow direction) in FIG. 6, the swing link 37 rotates in the counterclockwise direction (arrow direction) in FIG. 6, and the width-adjusting roller 20 descends.

Further, as shown in FIG.
The two arm portions 32a and 32b are fitted in the locking holes 7h and 8h (see FIG. 4) of the pressure members 7 and 8, respectively, and the rotating shaft 10 is rotated clockwise (in the direction of arrow) in FIG. When moved, the pressure members 7 and 8 are configured to be pushed down. Therefore, by rotating the rotating shaft 10 in the clockwise direction in FIGS. 5 and 6, the pressure members 7 and 8 are pressed against the medium 1 in synchronization with the pressing of the width-shifting roller 20 against the medium 1. it can.

Since the pressing of the width-shifting roller 20 against the medium 1 and the pressing of the pressure members 7 and 8 against the medium 1 are performed by the rotation of one rotation shaft 10, the width is reduced. The processing tolerance or the like may also be a situation in which one of the approaching roller 20 and the pressure members 7 and 8 has moved to the end point position and stopped, but the other has not reached the end point position at this point. In order to eliminate such an inconvenience, for example, the intermediate link 36 may be divided into two in the longitudinal direction, and a buffer mechanism such as a tension spring may be provided between the two.

The rotation drive of the descending width-adjusting roller 20 is
This is performed by a width-shifting motor (not shown). This width-shifting motor is composed of a stepping motor or the like, and its rotation output is transmitted to the width-shifting shaft 44 via the pulley 41, the belt 42, and the pulley 43, and is transmitted to the width-shifting shaft 44, as shown in FIG. It is configured to rotate the attached bevel gear 45.

As shown in FIG. 3, a bevel gear 46 meshes with the bevel gear 45, and further, the bevel gear 46.
A spur gear 48 is connected to the shaft via a shaft 47.
Here, the shaft 47 also rotatably supports the corner portion of the L-shaped swing link 37 (see FIG. 6), and itself is rotatably supported by a stationary member (not shown) on the housing side. ing.

The spur gear 48 meshes with a spur gear 49 provided coaxially with the width-shifting roller 20. Therefore, when the width-shifting motor is driven, the width-shifting shaft 44 rotates,
The rotation is bevel gear 45, bevel gear 46, shaft 4
7, the spur gear 48, the spur gear 49, and the width-shifting roller 20.
And the width-shifting roller 20 is rotated.

The width-shifting sensors 51 and 52 in FIG. 2 detect the medium 1 and are arranged in the vicinity of the abutting member 15 on the upstream side and the downstream side. The insertion sensor 53 is a sensor that detects that the medium 1 has been inserted from the insertion port 2, and is arranged at the center of the transport path 3 in the width direction. These sensors 51 to 53 are a pair of a light emitting element and a light receiving element, and detect the absence / presence of the medium 1 by transmitting / blocking (blocking) light between the two.

The output signals of these sensors 51 to 53 are input to a control unit (not shown) that executes a width-shifting operation, and based on these signals, the control unit causes the control unit to convey the motor, the pinch roller, and the width-shifting motor. , The solenoid 12, etc. are controlled. In the series of width-shifting sequences performed by this control unit, the drive for bringing the medium 1 into contact with the abutting member 15 is performed until the medium 1 is abutted against the abutting member 15 until the positioning is started and the medium 1 is finished. It is characterized in that it is repeated a plurality of times with the driving in the opposite direction interposed therebetween.

Next, using the flowchart of FIG.
The width-shifting operation of this embodiment will be described. In the initial state, the pinch roller is in a state of being separated from the conveying rollers 4 and 5 (conveying roller open state), and the width adjusting roller 20 and the pressure members 7 and 8 are moving upward and retracted from the conveying path 3 (width The pulling roller is open and the pressure member is open. The pinch roller is in contact with the conveying rollers 4 and 5 (conveying roller close state).

In this state, when the insertion sensor 53 detects that the medium 1 has been inserted into the insertion port 2, the conveyance rollers 4,
5 is driven to convey the medium 1 inserted between the conveying rollers 4 and 5 and the pinch rollers to the width-adjustment execution position and stop (S1). Then, the solenoid 12 is driven and the rotating shaft 10 is rotated. 5 and 6 is rotated clockwise by a certain angle. As a result, the width-adjusting roller 20 moves the medium 1
Then, the pressure members 7 and 8 press the medium 1 (S2). After shifting to this state, the pinch roller is separated from the transport rollers 4 and 5 (S3).

Next, the step of executing a specific width adjustment of the medium 1 will be described. Before starting the width adjustment, the position of the medium 1 is confirmed. As shown in FIG. 8, when the sensors 51 and 52 do not detect the medium 1 (S4), first, the width adjustment roller 20 is normally rotated. Then, the medium 1 is moved in the abutting direction and brought into contact with the abutting member 15 (S6), and then the width-adjusting roller 20 is rotated in the reverse direction so that the medium 1 is not detected by the sensors 51 and 52. It is separated from the abutting member 15, and the width-shifting roller 20 is again rotated in the forward direction to move the medium 1 in the abutting direction to abut the abutting member 15. In this way, the width-shifting roller 20 is caused to alternately perform normal rotation and reverse rotation, and the abutting operation by the forward rotation of the width-shifting roller 20 is repeated N times (a plurality of times) (S4 to S7). That is, the drive for bringing the medium 1 into contact with the abutting member 15 is repeated N times with the drive in the opposite direction for separating the medium 1 from the abutting member 15 in between.

On the other hand, at the time of executing the specific width adjustment of the medium 1, as shown in FIG.
9 is detected (the over-abutting state is shown in FIG. 9, but it is also the case when it is not over-abutting), first, the sensor 5 is moved in the direction in which the medium 1 is once separated from the abutting member 15.
1, 52 move until the medium 1 is no longer detected (S4
~ S5). After that, as in the case of FIG. 8, the medium 1 is moved in the abutting direction and brought into contact with the abutting member 15 (S6), and then the sensor 51, The medium 52 moves until it no longer detects the medium 1, and again moves the medium 1 in the abutting direction to abut the abutting member 15. This abutting operation is repeated N times as in the case of FIG. 8 (S4 to S7). Here, the number of repetitions of the abutting is, for example, about several times (N = 5), and the repetition speed is about 5 times per second.

When the number of repetitions reaches N (S7),
After the driving of the width-shifting roller 20 is stopped (S8) and the medium 1 is pressed against the conveying rollers 4 and 5 by the pinch roller (S8).
9) Then, the width-shifting roller 20 and the pressure members 7 and 8 are moved upward to be retracted from the transport path 3 (S1).
0). After that, the conveying rollers 4 and 5 are driven to carry the medium 1 into the inside (S11). During this loading, the sensors 51, 5
When the skew feeding is detected from the output of 2, the process returns to the step S4 and the above operation is repeated.

In the present embodiment, since the width-shifting roller 20 is caused to alternately perform forward rotation and reverse rotation, the medium 1 vibrates in the width direction, and as a result, the medium 1 and its abutting surface are vibrated. The sliding friction force becomes small, and the sliding of the medium 1 in the width direction becomes smooth. Further, even if the over-abutting is performed by this drive, the over-abutting state is eliminated, the medium 1 can be easily moved to the reference position in the width direction, and the posture (skew) of the medium 1 is also corrected. it can.

Furthermore, since the pressure members 7 and 8 press the medium 1 when the width-shifting roller 20 is driven, the curvature of the medium 1 is corrected during the positioning operation, and the flatness of the medium is maintained. Even with a closed passbook or thick medium,
The medium 1 does not come into strong contact with the uneven portion (obstacle) of the transport path 3, and the sliding frictional force in the width direction of the medium 1 does not become excessively large. Therefore, the medium 1 can be more stably moved to the reference position in the width direction.

Further, by providing the pressure members 7 and 8 with the pressure rollers 7a, 7b, 8a and 8b, the sliding frictional force in the width direction of the medium 1 is further reduced, and the medium 1 can be easily moved. The medium 1 can be more stably positioned at the reference position in the width direction.

In the above embodiment, the pressure members 7, 8 are
A pair of fitting portions are coaxially formed at a predetermined interval, and the pair of fitting portions are rotatably fitted to the drive shaft 6 so as to sandwich the transport rollers 4 and 5 from the axial direction. Therefore, the pressure members 7 and 8 can be easily attached. Further, in this embodiment, the pressure members 7 and 8 are provided in the vicinity of the transport rollers 4 and 5 which are also uneven portions of the transport path 3.
Because of the arrangement, the contact between the medium 1 and the concavo-convex portion of the transport path 3 can be efficiently eliminated even with a closed passbook or a thick medium.

Further, the push arm 31 is fixed to the rotating shaft 10, and the width-adjusting roller 20 is rotatably attached to the tip of the swinging link 37 whose tip can be lowered, so that the rotating shaft 10 is rotated at a fixed angle. By rotating, the movement of the pushing arm 31 is transmitted to the swinging link 37 via the link mechanism to press the width-shifting roller 20 against the medium 1. Therefore, the width-shifting roller 20 can be easily moved up and down. .

Further, the pressure members 7 and 8 are fitted to the drive shaft 6 so as to be able to descend, and the base end portion of the elevating arm 32 whose tip end engages with the pressure member 7 and 8 is fixed to the rotary shaft 10. Therefore, the rotating shaft 10
Is rotated by a certain angle, in synchronization with the pressing of the width-shifting roller 20 against the medium 1, the pressure members 7, 8 are synchronized.
Can be pressed against the medium 1, which simplifies the structure.

A driven arm 11 protruding in the radial direction of rotation is provided at one end of the rotary shaft 10, and a solenoid 12 having a constant stroke is provided at the tip of the driven arm 11.
Since the output shafts are connected and the rotating shaft 10 is rotated forward and backward by a certain angle, the rotating range of the rotating shaft 10 can be accurately set, and the pressure members 7, 8 and the width-adjusting roller 20 are lowered. The position can be set accurately.
