The page break operation, which will be described later with reference to FIG. 29, is controlled. In each of FIGS. 24 to 29, only the components necessary to explain the operation among the components described with reference to FIG. 24 are shown.

First, when the booklet medium 1 is inserted into this mechanism with a predetermined page open and a page break is made by turning one of the inner sheets 1a, the booklet medium 1 passes through a predetermined transport path. When conveyed to the position shown in FIG. 24, the clamp roller 2 is locked and fixed by a lock mechanism (not shown). At this time, the pinch roller 5 is in a state of pressing the booklet medium 1 against the rotating body 4 by the urging force of the spring 12.

[0017]

However, in the above-mentioned conventional automatic page breaker, only one inner sheet 1a of the booklet medium 1 is inflated by the inflating operation shown in FIG. Should turn only the booklet medium 1
There is a case where a plurality of inner paper sheets 1a are inflated and the plurality of inner paper sheets 1a are rolled as they are. In such a case, since the process cannot be executed as it is, it is necessary to eject the booklet medium 1a and return it to the operator or the like to turn the pages manually.

The following factors can be considered as factors that cause the two or more inner sheets 1a to be rolled up as described above. Usually, the bending stiffness (buckling force) of the paper itself is more than the force that causes the second paper to swell due to the friction between the first inner paper to be rolled and the second inner paper below. Is large, the second inner paper does not swell.

However, for example, when the stiffness of the paper is weakened by the moisture absorption of the inner paper, or when the inner paper is deformed (warped in the bulging direction), the binding portion of the booklet medium 1 becomes weak. If the buckling force of the inside paper is reduced due to such a situation, the frictional force between the first and second sheets becomes larger and the second inside sheet also expands. The same situation occurs when the friction between the inner sheets is large due to deformation or printing.

The present invention was devised in view of the above-mentioned problems, and inflates only one inner sheet during the inflating operation to surely realize the page break operation one by one,
An object of the present invention is to provide a highly reliable automatic page break method and automatic page break device that do not bother an operator or the like.

The plate 70 and the lock magnet 7 are connected to the driving force transmission system 1) so that the clamping roller 41 can be locked / fixed at the time of a page break operation so that the driving force transmission system can be disconnected.
1, a lock mechanism including a drive member 72, a spring 73, and a lock gear 74 is provided. That is, the gear 64
A plate 70 is rotatably attached to the rotary shaft 64a, and a gear 63 is rotatably attached to the plate 70. A drive member 72 of the lock magnet 71 is rotatably connected to the plate 70 via a rotary shaft 72a.

The lock magnet 71 is an electromagnet mechanism, which moves the position of the drive member 72 by switching between excitation and non-excitation, thereby rotating the plate 70 around the rotation shaft 64a and fixing the gear 63 to the pulley gear 62 or fixed. One of the lock gears 74 is engaged with the other. The plate 70 is biased by a spring 73 in a direction in which the gear 63 meshes with the pulley gear 62.

Therefore, in the non-excited state of the lock magnet 71, the driving member 72 is arranged at the position shown by the solid line in FIG. 6, the gear 63 meshes with the pulley gear 62, and the rotational driving force from the pulse motor 53 is the same as that described above. It is adapted to be transmitted to the rotary shaft 35 and the clamp roller 41 via the driving force transmission system. Also, the lock magnet 71
6, the plate 70 rotates around the rotation shaft 64a against the urging force of the spring 73 by the movement of the drive member 72 to the left in FIG. 6, and the gear 63 shows the dotted line in FIG. As shown by, it is separated from the pulley gear 62 and meshes with the non-rotating lock gear 74. As a result, the drive force transmission system from the pulse motor 53 is disconnected, and the rotary shaft 35, the clamp roller 41, the rotary shaft 33, and the medium carrying roller 3 are cut off.
6 can be switched to a locked / fixed state in which it does not rotate at all. In FIG. 3, the pulley gear 62, the gears 63, 63, the pulley 65, the plate 70, the lock magnet 71, the drive member 72, and the spring 7 described above are used.
3, illustration of the lock gear 74 and the like is omitted.

By the way, in the apparatus of this embodiment, as shown in FIG. 7, the pulse motor 5 described above with reference to FIGS.
3, a control unit 76 for controlling the operations of the lock magnet 71 and the roller magnet 51 is provided. The control unit 76 performs the control operation according to the flowchart shown in FIG. 9, and based on the detection signals from the sensors 46A, 46B. The page break operation is controlled as will be described later with reference to FIGS.

Next, the operation of the automatic page breaker of the present embodiment constructed as described above will be described with reference to FIGS. 10 to 23 according to the flowchart (steps S1 to S24) shown in FIG. In each of FIGS. 10 to 18, among the constituent parts described with reference to FIGS.
Only the components necessary to explain the operation are shown. 19 to 23 are schematic side views for explaining the principle of the preliminary expansion operation by the page break mechanism of this embodiment.

When performing page break processing on the booklet medium 31, first, the rotational driving force from the pulse motor 53 is transmitted through the driving force transmission system and the rotary shafts 33 to 35 to the medium conveying roller 36 and the page turning roller. 37, clamp roller 41
Is transmitted to the booklet medium 31 by the rotation of these rollers 36, 37, 41 (counterclockwise rotation in the figure).
Is conveyed to the position (page break position) shown in FIG. 10 while being sandwiched between the pinch rollers 42 and 47 (step S1), and the pulse motor 53 is stopped (step S).
2).

At the page break position, as shown in FIG. 10, the booklet medium 31 is sandwiched between the clamp roller 41 and the pinch roller 42 on the side of the binding portion 31b, and is turned over to the end side of the inside paper 31a to be turned. 37 comes into contact. At such a page break position, the lock magnet 71 is turned on (excitation state) (step S3), the drive force transmission system from the pulse motor 53 is cut, and the rotary shaft 35 and the clamp roller 41 are not locked at all and locked. The booklet medium 31 is fixed by switching to the state.

At this time, the roller magnet 51 is in the non-excited state, and as shown in FIG.
Is in a state of pressing the booklet medium 31 against the page-turning roller 37, and in such a state, the pulse motor 53
Is operated to rotate the turning roller 37 counterclockwise (step S4). As a result, as shown in FIG. 11, the inner paper 31a that contacts the turning roller 37 starts to swell due to the frictional force on the surface of the turning roller 37. The rotational drive of the turning roller 37 in step S4 is performed until the paper guide 43 is pushed up by the swelling of the inner sheet 31a and the sensor 46A is turned on (step S5), that is, the swelling amount reaches a predetermined amount. , The opening degree (rotation angle) of the paper guide 43 reaches a predetermined angle,
It is continued until the light blocking state by the blocking portion 45a is released.

When the sensor 46A is turned on, FIG.
As shown in, the roller magnet 51 is turned on (excited state) (step S6), and the pressing state of the booklet medium 31 against the page-rolling roller 37 by the pinch roller 47 is released. In this state, the pulse motor 53 is operated to further rotate the turning roller 37 counterclockwise (direction of arrow A in FIG. 12) by a predetermined step (step S
7) The rotation direction of the pulse motor 53 is reversed, and the turning roller 37 is rotationally driven clockwise (direction of arrow B in FIG. 12) by a predetermined step (the same amount as in step S7) (step S8).

By such a preliminary expanding operation (preliminary expanding operation), as will be described later with reference to FIGS. 19 to 23, even when two or more sheets of inner paper 31a are inflated, the inner paper 31a is rolled up. It is possible to separate one sheet that comes into contact with 37 and the other sheet, and drop the inner sheets 31a after the second sheet. After this preliminary inflating operation, a normal inflating operation (main inflating operation) and a repelling operation that are generally performed are performed. That is, the roller magnet 51 is turned off again (non-excited state) (step S9),
Rolling roller 37 for booklet medium 31 by pinch roller 47
Then, the lock magnet 71 is turned off (non-excited state) (step S10), and the clamp roller 41 is released from the locked / fixed state.

In this state, the pulse motor 53 is operated to rotate the rollers 36, 37, 41 clockwise (step S11), and the booklet medium 31 is inserted into the insertion port 30.
The sheet is returned in the a direction (left side in the figure) and is conveyed to the main inflating operation position as shown in FIG. At this time, the turning roller 37
Is located on the left side of the binding portion 31b of the booklet medium 31 and substantially in the center of the inside paper 31a to be turned.

In this embodiment, steps S3 to S9.
By the pre-inflation operation and steps S12 to S described later.
With the main inflation operation by 16, the arrangement position of the booklet medium 31 is changed. The larger the distance between the page turning roller 37 and the binding portion 31b of the booklet medium 31 (the position of the clamp roller 41 in the preliminary expansion operation shown in FIGS. 11 and 12), the weaker the restoring force of the inner paper 31a and the easier it is to perform a page break. Therefore, at the time of the preliminary expansion operation, first, the booklet medium 31 is arranged at a position where the restoring force of the inner paper 31a is the weakest, and only the first inner paper 31a to be rolled is surely inflated,
During the main inflation operation, the second and subsequent inner sheets 31a are arranged in a state where the restoring force is large, and the first inner sheet 31a is arranged.
Only inflated so that it can be flipped up.

Now, in step S11, the booklet medium 3
1 is placed in the full inflation position, the sensor 46A
Confirms the on / off state (step S12). If the sensor 46A is in the ON state, it is determined that the amount of swelling of the inner paper 31a is sufficient, and the process moves to the flip-up operation after step S17. If the sensor 46A is in the off state, the lock magnet 71 is turned on (excited state) at the main inflation position (step S13), the driving force transmission system from the pulse motor 53 is disconnected, and the rotary shaft 35 and The clamp roller 41 is switched to a locked / fixed state in which it does not rotate at all, and the booklet medium 31 (the already-wrapped portion on the right side of the binding portion 31b in the drawing) is fixed.

In this state, the pulse motor 53 is operated to rotationally drive the turning roller 37 counterclockwise (step S14), and as shown in FIG. Further, it is further expanded by the frictional force on the surface of the turning roller 37. In the rotational driving of the turning roller 37 in step S14, the paper guide 43 is pushed up by the swelling of the inside paper 31a, and the sensor 46A.
Continues until is turned on (step S15).
When the sensor 46A is turned on, the lock magnet 71 is turned off (non-excited state) (step S16), and the locked / fixed state of the clamp roller 41 is also released.

Then, the pulse motor 53 is operated to drive the rollers 36, 37 and 41 to rotate counterclockwise (step S17), and the booklet medium 31 is again sucked to the right side in the drawing, as shown in FIG. It is transported to the rebounding position.
At this flip-up operation position, the lock magnet 71 is turned on (excitation state) (step S18), the drive force transmission system from the pulse motor 53 is cut off, and the rotary shaft 35 and the clamp roller 41 are not locked at all and locked. The booklet medium 31 is fixed by switching to the state, the roller magnet 51 is turned on (excited state) (step S19), and the state where the pinch roller 47 presses the booklet medium 31 against the page-rolling roller 37 is released.

In this state, the pulse motor 53 is operated to rotationally drive the repelling roller 38 counterclockwise by a predetermined number of steps (step S20). At this time, of course,
The turning roller 37 also rotates integrally with the flip-up roller 38. As a result, as shown in FIG. 16, the first inner sheet 31a is repelled, and the first inner sheet 31a is passed over the turning roller 37, the repelling roller 38, and the guide roller 39 to be completely separated. This flip-up is detected when the sensor 46B changes from the off state to the on state. Step S21
If the sensor 46B cannot detect the ON state of the sensor 46B by determining the ON / OFF state of the sensor 46B, it is determined that a normal page break operation cannot be performed, and error processing is performed. Transition.

When the on-state of the sensor 46B is detected, as shown in FIG. 17, the lock magnet 71 is also turned off (non-excited state) (step S22), and the locked / fixed state of the clamp roller 41 is released. With
The roller magnet 51 is turned off (non-excited state) (step S23) and the pinch roller 47 presses the booklet medium 31 against the page-rolling roller 37.

Then, as shown in FIG. 18, the pulse motor 53 is operated to rotationally drive the rollers 36, 37 and 41 in the clockwise direction (step S 24), and the booklet medium 31.
While pulling out to the insertion opening 30a (left side in the drawing), the flipped up inside paper 31a is turned over, and the page break operation is completed. Next, referring to FIGS. 19 to 23, steps S3 to S described above are performed.
The principle of the preliminary expansion operation by the page break mechanism of this embodiment, which is executed in 9, will be described.

Here, in the figure, μ1 is the friction coefficient between the inner paper 31a and the turning roller 37, μ2 is the friction coefficient between the inner paper 31a (where μ1> μ2), and P is the inner paper 31a turning roller. 37, a force for inflating the first inner paper 31a, a force for inflating the second inner paper 31a, a force for inflating the second inner paper 31a,
Q and Qh are restoring forces that cause the inner paper 31a to swell and bend and return to the original state, Q is a tangential force at the contact point between the turning roller 37 and the inner paper 31a, Qh is a horizontal restoring force, and ω
Is an angle within a range where the inner paper 31a and the turning roller 37 are in contact with each other.

First, the booklet medium 3 is moved by the pinch roller 47.
1 is pressed against the turning roller 37, the pulse motor 5
Rolling roller 37 in the direction of inflating inner paper 31a by 3
To rotate. At this time, when P1> Q and P2> Q from the state shown in FIG. 19, both inner sheets 31a begin to swell as shown in FIG. 20, and the surface of the winding roller 37 is stronger than the restoring force of the inner sheet 21a. Inflate until the frictional force is large.

The sensor 46A causes the inside paper 31a to be a predetermined amount.
When it is detected that the swelling has occurred, the pinch roller 47 is opened as shown in FIG. At this time, P1 = Q and P2 = Q, and the two inner paper sheets 31a remain inflated. In this state, the page motor 31 is rotated by the pulse motor 53 by a certain number of steps in the direction in which the inner sheet 31a is further expanded.

At this time, the force P1 for inflating the first inner sheet 31a is given by the frictional force of the portion in contact with the turning roller 37 (angle 0 to ω) as shown in the following formula (1). Meanwhile, the force P2 for inflating the second inner sheet 31a is 1
The frictional force between the first inner sheet 31a is given by the following equation (2).

[0070]

[Equation 1]

Since there is a relationship of μ1> μ2, naturally P1> P2, and as shown in FIG. 22, the second inner paper 31a is displaced from the first inner paper 31a. Cause Then, the turning motor 37 is driven by the pulse motor 53.
Is rotated by the predetermined steps in a direction opposite to the direction in which the inner paper 21a is inflated. By slightly returning the inflated state in this way, as shown in FIG. 23, the first inner sheet 31a is turned over by the friction roller 37 by the frictional force when P1> Q.
It remains attached to the second inner paper 31a.
Completely separates from the first inner sheet 31a, and the bulge disappears, resulting in a substantially flat state.

Thus, according to one embodiment of the present invention,
Even when a plurality of inner papers 31a are inflated by performing a preliminary inflating operation on the inner paper 31a of the booklet medium 31 at the time of starting the page break operation for the booklet medium (when inflating operation), Since the paper 31a can be separated into one sheet that comes into contact with the turning roller 37 and another sheet, the subsequent processing can be smoothly performed,
The page break operation for each page is surely executed, and an extremely reliable page break operation that does not bother an operator or the like can be realized.

In the above-described embodiment, the case where the present invention is applied to the passbook printer to perform page break of the passbook as the booklet medium 31 has been described, but the present invention is not limited to this. Not only can it be applied to a mechanism for automatically turning the inside paper of a passbook in a cash transaction machine, etc., but it can also be applied to a mechanism for making page breaks by binding various slips as a booklet medium. In this case as well, it is possible to obtain the same effects as those of the above-described embodiment.

[0074]
