Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic page feed mechanism for a passbook entry machine installed in a financial institution such as a bank or a post office to print on a passbook.

[0002]

2. Description of the Related Art FIG. 4 is a schematic diagram showing a conventional automatic page break mechanism. In FIG. 4, reference numeral 21 denotes a passbook, which is formed into a booklet by binding a front cover, a spine cover, and a plurality of inner sheets 22 to a center hold 21a that is the center of folding. Reference numeral 23 denotes a page break roller, which has a proper friction on the circumferential surface, and a part of the circumferential surface is brought into contact with the inside paper 22 to rotate the page break roller 23 to flip the inside paper 22. .. A pinch roller 24 is provided so as to face the page break roller 23 and to move in a direction of approaching and separating from the page break roller 23.
At the time of page break, the passbook 21 is pressed against the page break roller 23.

Reference numeral 25 is a separator, and one end of each separator has an arc portion 25a located inside the circumferential surface of the page-break roller 23. In addition, the other end of each is the inclined portion 2
It has 5b and is supported by a rotation fulcrum 26 so as to face each other. 27 is a spring and the separator 25
Is stretched in the direction to open the outside. 28 is a plunger magnet for opening and closing the separator 25, and 29 is the plunger magnet 28 and the lever 30.
Is a link that connects. The lever 30 rotates at a rotation fulcrum 31 so as to be retracted from the inclined portion 25b of the separator 25 by the operation of the plunger magnet 28. Reference numeral 32 is a spring that engages the lever 30 with the inclined portion 25b of the separator 25 with a stronger force than the spring 27 stretched around the separator 25.

When the plunger magnet 28 is excited as shown in FIG.
Link 29 around the rotation fulcrum 31 by overcoming the tension of 2
The separator 25 rotates so as to retract from the inclined portion 25b of the separator 25. Then, the tension of the spring 27 causes the separator 25 to open around the rotation fulcrum 26.

Next, the page-breaking operation of the conventional passbook will be described with reference to FIGS. 4 and 5. First, the passbook 21 is conveyed and stopped at a predetermined position where the page feed roller 23 and the page to be paged face each other.
Then, the passbook 21 is sandwiched between the pinch roller 24 and the page-breaking roller 23, and the page of the passbook 21 to be page-changed is fed by the page-breaking roller 2.
Press into contact with 3. Subsequently, if the page break roller 23 is rotated in the direction of arrow A without rotating the pinch roller 24, the page to be paged is turned. When the page break roller 23 turns a certain amount, the pinch roller 24 is released from pressure contact, and the page break roller 23 is further rotated to move the inside paper 22 to the page break roller 23.
Bounce up more.

Next, when the pinch roller 24 is pressed against the passbook 21 and the plunger magnet 28 is excited, the separator 25 opens as shown in FIG.
Is separated from the page feed roller 23. While maintaining this state, the page feed roller 23 is rotated in the direction of arrow B to pass the passbook 21.
Is conveyed in the direction of arrow G to complete the page break. When the excitation of the plunger magnet 28 is released, the tension of the spring 32 returns the separator 25 to the state shown in FIG.

[0007]

However, in the automatic page-breaking mechanism having the above structure, when the inside paper 22 is pulled away from the page-breaking roller 23, the separator 2 is pulled by the tension of the spring 27.
5 was open. Further, the lever 30 is engaged with the inclined portion 25b of the separator 25 by using the spring 31 having a stronger force than the tension of the spring 27. Therefore, the plunger magnet 28 is required to overcome the strong tension of the spring 31, and as a result, the plunger magnet 28 becomes large and power consumption increases.

According to the present invention, in order to prevent the page to be changed from being rolled up, the page to be changed is retracted to the position where it is separated from the page change roller. With a simple structure, the power consumption of the apparatus can be reduced. The purpose of the present invention is to provide an automatic page break mechanism.

[0009]

A first solution provided by the present invention to solve the above-mentioned problems is a conveyance path for conveying a passbook and a passbook fixed to a rotary shaft provided on the conveyance path. A page break roller that rotates in the page break direction and the conveyance direction in contact with the turning page, a pinch roller that presses the passbook against the page break roller at the time of page break of the passbook and during conveyance, and a page break page that is the page break roller. In an automatic page break mechanism having a separator that rotates so as not to contact and a drive mechanism that rotates the separator, one end of the separator is rotatably attached to the drive mechanism, and the other end is a flipped page. A contact portion that is in contact with and a cut portion is provided in the contact portion,
The rotary shaft is inserted into the cut portion, and the separator is rotated within the range of the cut portion.

As a second means for solving the problem, a passbook is held by a page break roller and a pinch roller fixed to a rotary shaft,
In the automatic page break mechanism for rotating the page break roller in the forward direction to turn the page, separating the turned page from the page break roller by the separator, and then reversing the page break roller to carry the passbook, the separator is Direction and the opposite direction thereof are rotatably disposed within a certain range, one end is rotatably attached to the rotary shaft of the page break roller, the other end is engaged with the separator, and the rotary shaft is attached by a sliding friction mechanism. A switching arm that rotates with the rotation to rotate the separator may be provided.

[0011]

According to the first solving means, the separator is directly driven by the driving means at the time of the page break operation, and the other end of the separator rotates within the range of the notch so that the inside paper is surely fed from the page break roller. Pull away. Since the separator is directly driven by the driving means, the number of springs used is smaller than in the prior art. Further, since the tension of the spring used may be relatively small, the driving means can be miniaturized.

According to the second solving means, when the page-break roller is rotated in the forward direction to turn over the page of the passbook, the switching arm is rotated in the same direction by the sliding friction mechanism as the page-break roller is rotated. Then, the separator is rotated in the transport direction. When the separator rotates by a certain amount, the rotation is stopped, but the page-break roller further rotates, and the page-turning page is turned over the page-break roller. Next, when the page break roller is rotated in the reverse direction, the switching friction arm is also rotated in the same direction by the sliding friction mechanism to rotate the separator in the direction opposite to the conveying direction, and the separator comes into contact with the page break roller to turn over pages. Pull it away from the page break roller. After that, the page feed roller is further rotated in the reverse direction, and the passbook is nipped and conveyed together with the pinch roller. As described above, only by the reverse rotation operation of the page-break roller, the page-turning page can be reliably separated from the page-break roller. Therefore, according to the second solution,
The driving means for driving the separator is not required, and the power consumption of the device can be greatly reduced.

The passbook 2 is formed by the pinch roller 24 and the page break roller 23.
1, the inside paper 22 of the passbook 21 is pressed against the page break roller 23. When the page break roller 23 is rotated in the direction of arrow A without rotating the pinch roller 24, the inside paper 22 is turned. When the page break roller 23 has turned a certain amount, the pinch roller 24 is released from the pressure contact, and the page break roller 23 is further rotated so that the inside paper 22 is flipped up above the page break roller 23. When the flipping up is completed, the page feed roller 23
Stop rotating. Next, the plunger magnet 8 is excited to rotate the separator 5 in the direction of the arrow D within the range of the cut 5a about the rotation fulcrum 6 as shown in FIG. Separate 22.
Continuing, while keeping the excitation of the plunger magnet 8,
The pinch roller 24 is again brought into pressure contact with the page break roller 23, and the page break roller 23 is rotated in the direction of the arrow B to cause the pinch roller 24 to rotate.

Next, referring to FIG. 3, description will be given of the case where the page is turned over too much when the page is turned and the back-turning operation is performed. First, the passbook 21 is conveyed to a predetermined position where it is turned over and stopped. Then, the plunger magnet 8 is excited, and the passbook 21 is sandwiched between the pinch roller 24 and the page break roller 23, and the inner paper 22b of the passbook 21 to be paged is brought into pressure contact with the page break roller 23. Then, the page break roller 23 is rotated in the direction of the arrow B to perform page break in the same manner as described above. When the energization of the plunger magnet 8 is released after the flipping up of the inside paper 22 is completed, the separator 5 is rotated by the tension of the reset spring 7 to a position where the inside paper 22b is separated from the page feed roller 23. Then, the passbook 21 is conveyed to a predetermined position and the returning operation is completed.

Next, a second embodiment of the present invention will be described in detail with reference to the drawings. FIG. 6 is a schematic configuration diagram of an automatic page feed mechanism showing a second embodiment of the present invention, and FIG. 7 is a schematic side view of the second embodiment.

In FIGS. 6 and 7, the separator 41 provided in the automatic page break mechanism 40 engages with a rotation fulcrum 42a formed on the support 42 and is rotatably suspended by this. .. The support 42 is fixed to a part of the device.
A stopper 42b is formed on the support 42,
The stopper 42b is loosely fitted in the long hole 41a formed in the separator 41 and regulates the rotation amount (angle) of the separator 41.

One end of the separator 41 has an arc portion 41b which is slightly smaller than the circumference of the page break roller 23.
A notch 41c is formed at the center of 1b. The rotary shaft 3a to which the page break roller 23 is fixedly passes through the notch 41c.

A switching arm 44 is rotatably attached to the rotary shaft 3a. A post 44a is formed at one end of the switching arm 44, and is movably engaged with another long hole 41d formed in the separator 41. Further, as shown in FIG. 7, two bosses 45 and 46 are fixed to the rotary shaft 43 on both sides of the switching arm 44.
An elastic member 47 is provided between the switching arm 44 and the switching arm 44.

The elastic member 47 uses, for example, a wave washer or the like, and is configured to press the switching arm 44 against the boss 45 by constantly applying a constant lateral pressure to the switching arm 44. Therefore, when the rotating shaft 3a rotates, the switching arm 44 also rotates in the same direction as the rotating shaft 3a due to sliding friction unless there is something that prevents the rotation of the post 44a of the switching arm 44. Then, the post 44a pushes the long hole 41d, whereby the separator 41 is rotated. Other structures are similar to those of the conventional art.

Next, the operation of the automatic page break mechanism in the above structure will be described with reference to FIGS. 6, 7 and 8. FIG. 8 is an explanatory view showing the page turning operation of the second embodiment of the present invention.

In FIGS. 6 and 7, the passbook 21 is conveyed between the page break roller 23 and the pinch roller 24 with the page break side first. At this time, the pinch roller 24 is moved to a position away from the page break roller 23, but when the passbook 21 is conveyed by a predetermined distance and stopped, the pinch roller 24 moves to the page break roller 23 side and together with the page break roller 23. The passbook 21 is clamped under pressure.

Next, the rotary shaft 3a is rotated to rotate the page break roller 2.
When 3 is rotated in the direction of arrow A, the inside paper 22 which is the page of the passbook 21 to be turned over is turned over, and the state shown in FIG. 6 is obtained.
Further, as the page break roller 23 is rotated, the switching arm 44 is also rotated by the frictional force generated by the side pressure applied by the elastic member 47.
It rotates in the direction of arrow A together with a. And switching arm 4
By the rotation of 4, the post 44a of the switching arm 44 pushes the separator 41, and the separator 41 rotates in the transport direction of the passbook 21, that is, in the arrow C direction.

After the inner paper 22 is turned by a predetermined amount by the page break roller 23, the pressing of the pinch roller 24 against the page break roller 23 is released, and the page break roller 23 is further rotated in the direction of arrow A. The tip 22a of the sheet jumps upward from the page feed roller 23.

On the other hand, the rotation of the separator 41 is stopped by the stopper 42b of the support 42 hitting the elongated hole 41a of the separator 41, but the elastic member 47 causes the switching arm to move while the rotating shaft 3a rotates. Continuing to slip on the surface of 44, the separator 41 is kept in the stopped state shown in FIG.

Next, when the rotary shaft 3a is reversely rotated to rotate the page break roller 23 in the direction of arrow B, the switching arm 44 is also rotated in the same direction by the frictional force between the elastic member 47 and the switching arm 44. To do. The rotation of the switching arm 44 causes the post 4 to move.
4a pushes the separator 41 to rotate it in the direction of arrow D,
As shown in FIG. 8, the inside paper 22 is separated from the page break roller 23 by the arc portion 41b.

In the above state, the rotation of the page break roller 23 is once stopped, the pinch roller 24 is pressed against the passbook 21 again, and then the rotary shaft 3a is rotated in the reverse direction to move the page break roller 23 to the arrow B.
And the pinch roller 24 is rotated in the arrow E direction to convey the passbook 21 in the arrow G direction. Separator 4
Although the rotation of No. 1 is stopped by the stopper 42b, the elastic member 47 slips on the surface of the switching arm 44, so that the separator 41 is kept in the stopped state and the non-contact state between the inside paper 22 and the page break roller 23 is maintained. It

Although the page break is completed as described above, the page turning operation in the case where two or more sheets of the inner paper 22 are turned and the page breaks will be described below with reference to FIG. FIG. 9 is an explanatory view showing the operation of turning over the pages in the second embodiment.

After the page break is completed, when it is detected that a plurality of pages are turned over by a detecting means (not shown), the page break roller 23 and the pinch roller 24 are rotated to convey the passbook 21 and perform a turning-back operation. Stop at the specified position.

Next, the page break roller 23 is rotated in the direction of arrow B to turn over the inside paper 22b to be returned. At this time, the switching arm 44 also rotates in the same direction, and the separator 41 rotates in the direction of arrow D. Then, after the inside paper 22b is turned over by a certain amount,
The pinch roller 24 is released from pressure contact, and the page break roller 2
3 is rotated, and the leading end of the inside paper 22b is flipped up from the page break roller 23 as in the page break operation.

Next, when the rotary shaft 3a is rotated to rotate the page break roller 23 in the direction of arrow A, the switching arm 44 is also rotated in the same direction, and the separator 41 is rotated in the direction of arrow C. Due to the rotation of the separator 41, the inside paper 22b that was in contact with the page break roller 23 is separated from the page break roller 23 by the arc portion 41b.

After the inner paper 22b is separated from the page break roller 23 by the arc portion 41b, the pinch roller 24 is pressed against the passbook 21 again, and then the page break roller 23 is rotated in the direction of arrow A to move the pinch roller 24. The passbook 21 is conveyed in the direction of arrow K by rotating in the direction of arrow J. At this time, since the separator 41 is stopped in the state of being rotated in the C direction,
When the passbook 21 is conveyed, the inside paper 22b is turned over.
It should be noted that the above operation is performed for the number of pages that have been turned over.

By the way, the rotation amount of the separator 41 is regulated by the stopper 42b coming into contact with the elongated hole 41a, but instead of providing the stopper 42b, the separator 4 is provided.
The notch 41c of No. 1 may be engaged with the rotation shaft 43 to regulate the rotation amount of the separator 41.

Further, instead of mounting the elastic member 47 between the switching arm 44 and the boss 46, for example, a rubber collar or the like is mounted on the rotary shaft 3a at the position where the switching arm 44 comes into contact with the rotary shaft 3a. When rotating, the switching arm 44 may be rotated by using the frictional force generated between the rubber collar and the switching arm 44, and the separator 41 may be rotated.

In the second embodiment, the separator 41 is operated by transmitting the rotational force of the rotary shaft 3a to the separator 41 via the switching arm 44 without using a dedicated power source, so that the first embodiment is adopted. Power consumption can be saved more than that.

[0037]

As described in detail above, according to the present invention, the separator is formed of a single member, and the turning of the separator separates the turning page from the page break roller. Therefore, the power consumption for driving the separator is reduced as compared with the conventional one. As a result, the power consumption of the device is also reduced.

Further, since the separator can be stopped within this rotation range, it is possible to surely perform a page break and turn over.
