DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a page turning apparatus and a page turning method for booklets including a plurality of sheets such as a passbook.

[0002]

2. Description of the Related Art A conventional page turning apparatus is disclosed in
As described in JP-A-00-168270, a recess is provided below the page changing roller on the transport path in order to prevent the pressing force from the page changing roller to the passbook from becoming excessive. A part of the passbook is resiliently submerged in the recess, so that when the turning member of the page changing roller presses the passbook, the contact area between the turning member and the page to be turned increases. Excessive pressing force applied to the passbook is prevented.

[0003] Japanese Patent Application Laid-Open No. 1-222996 discloses a configuration in which a convex portion is provided on a part of a transport path.

[0004]

Problems to be Solved by the Invention JP-A-2000-168
The depression described in Japanese Patent Publication No. 270 aims to prevent the pressing force applied to the passbook from being excessive as described above. In order for the passbook to be elastically deformed, the size of the recess must be large enough to be covered by the passbook. Therefore, the size of the concave portion needs to be equal to or slightly larger than the outer radius of the page changing roller.

[0005] In this case, when the booklet is thick or the rigidity of the paper sheets constituting the booklet is high, the bending rigidity is proportional to the cube of the thickness and the rigidity of the paper sheet itself. It is difficult to obtain the effect of reducing the pressing force by absorbing the pressing force of the page changing roller due to the elastic deformation.

In the case of a passbook as an example, the thickness of the passbook differs depending on whether the number of pages to be turned is large or small, and it is difficult to always obtain a stable effect.

Further, if the passbook has a fold or curl and the paper is deformed along the shape of the recess, the reaction force from the passbook does not act on the pressing force of the page changing roller. However, the effect of the concave portion cannot be obtained, and conversely, it may be a cause of non-pick or turning over of two sheets. In addition, since the deformation behavior of the paper becomes complicated, if the buckling mode of the paper, which is a resistance when turning pages, becomes complicated, excessive page turning resistance will occur, and the pages will be turned halfway and transported. Jams may occur due to this.

In this case, it is necessary to change the shape of the recess, control the spring force of the pressing member, add a damping material, etc., and the structure becomes complicated.

The projections described in Japanese Patent Application Laid-Open No. 1-222996 are provided for deforming booklets in a primary bending mode, but handle booklets having different thicknesses and paper qualities. In this case, if it is attempted to provide a bow-shaped warp with respect to the booklet front page, that is, to give a first-order bending mode, it is necessary to form a large convex portion.

However, there is a limitation in increasing the size of the convex portion because the convex portion blocks the transport path.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a page turning apparatus and a page turning method for stably changing pages of a booklet.

[0012]

In order to achieve the above object, for example, there is provided a transport path for booklets and a page change roller for turning over pages of the booklets, and is opposed to the page change roller of the transport path. A position is provided with a concave portion depressed from the booklet conveying surface of the conveying path, and a convex portion protruding from the booklet conveying surface of the conveying path is provided at an end of the concave portion in the booklet conveying direction.

With this configuration, a predetermined range of page turning force can be stably generated without relying on the elastic deformation reaction force of the passbook or the spring force of the pressing member. The buckling mode, which is a page turning mode, becomes the primary bending mode.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below.

FIG. 1 is a block diagram showing an embodiment applied to a passbook page turning apparatus of the present invention. The passbook page turning device is mounted on, for example, an automatic cash transaction device or a passbook entry device, and prints a transaction history on the passbook. When it is necessary to turn the page of the passbook, turn the page.

The page turning apparatus of this embodiment has a hollow structure made of an elastic material such as rubber, and has a page turning portion 1a made of a member having a large friction coefficient and a core portion 1b made of a low friction member. A page changing roller 1, a pair of conveying rollers for conveying booklets, a paper guide 11, a page changing guide 3, a slope portion 4b and a lower flat portion 4c having an uneven shape between the page changing roller 1 and the conveying roller pair. A transport path 4 for guiding the bottom of the passbook to be transported, a transport space for securing the transport when the passbook is transported, and a shutter 5 that is opened when turning pages, and connected to at least the page changing roller 1 and the driving roller 7. It is formed by a page turning control device (not shown) that controls these rotations.

The transport roller pair is supported by an elastic member such as a spring, and is movable in the thickness direction of the passbook.
And a drive roller 7 which comes into contact with the transport roller 6 or the passbook to be transported, and pinches and transports the passbook with the transport roller 6.

The slope portion 4b is a region on the transport path connecting the convex portion and the concave portion, and is a convex portion protruding from the passbook transport surface of the transport path 4 and a concave portion recessed from the passbook transport surface of the transport path 4. It is connected to the lower flat portion 4c and is provided on both sides of the page change roller 1.

The length L ₁ from the rotation center of the page replacement roller 1 to folding of the distal end of the paper guide 11 is determined by the spread length of the passbook, in this embodiment, for example, spread the length of the passbook in the world The length is shorter than 63.5 mm to 91.5 mm, which is half of 127 mm to 183 mm.
Handling defines a length L ₁ by passbook, a structure for holding the passbook by the conveying roller 6 and the driving roller 7 when turning pages.

Further, the tip of the convex portion of the slope portion 4b provides a trigger for changing the buckling mode of the page to be turned into the primary bending mode. Distance L ₂ from the convex mold portion distal to the rotational center of the page replacement roller 1 is about approximately half the length L _1. This is because the tip of the convex part is a trigger and is near the antinode (maximum amplitude) of the first-order mode of the formed bending.

Further, the distance L ₃ to the rotational center of the the lower flat portion 4c page replacement roller 1 has a maximum outer circumference R is smaller than the page turning portion 1a of the page replacement roller 1. This is to generate an appropriate page turning force even when the passbook is extremely thin. Passbook thickness and the distance L
₃ and the sum of the difference between the maximum outer circumference R of the page turning roller 1 of the page changing roller 1 is the page turning portion 1 of the page changing roller 1.
a. The relationship between the maximum outer peripheral R and the distance L ₃ will be described later.

The distance from the lower flat portion 4c to the shutter 5 is at least larger than the thickness of the passbook. It will be described later distance h ₁ to the convex tip of the lower flat portion 4c and the inclined surface portion 4b.

FIG. 2 shows a page turning section 1 having a hollow structure.
It is a figure which shows the mechanical characteristic of a. In an elastic body such as rubber having a hollow structure, when compressed and deformed as shown in the figure,
A non-linear phenomenon called Snap-Through occurs. In this phenomenon, the relationship 10 between the deformation and the reaction force is not linear, and the increase in the amount of deformation is significantly larger than the increase in the reaction force.
0a is present. In this page change, the page is changed in the non-linear area 10a of the drawing, that is, an area in which the change in the reaction force is small even if the passbook thickness changes. In other words, the relationship between the distance L ₃ between the maximum outer peripheral R and the lower flat portion 4c of the page turning portion 1a to the rotational center of the page replacement roller 1 is defined by the non-linear region 10a.

[0024] Here, the reaction force corresponds to the force applied to the passbook during page replacement, the sum of the difference between the maximum outer circumference R of the page turning portion 1a of the thickness and the distance L ₃ and page replacement roller 1 of the passbook deformation The quantity X. In a two-page spread passbook, the thickness of the turning-side passbook differs depending on whether the number of pages on the turning side is large or small, but if the difference in the thickness is within the range of the non-linear area 10a, the page is turned on. There is little change in the force given to the passbook when changing pages, and stable page changing can be performed.

[0025] That is, the distance L ₃ of the maximum outer peripheral R and a lower flat portion 4c to the rotational center of the page replacement roller 1, so as to be within the scope of the non-linear region 10a by a difference in thickness of the side of the page turning Is determined.

The passbook conveyed to the page turning device to change pages is conveyed by the conveying roller 6 and the driving roller 7 so that the front end of the passbook in the conveying direction is on the lower flat portion 4c and the downstream slope in the conveying direction. It is set at a predetermined position before the portion 4b is engaged. That is, the lower flat portion 4 of the present embodiment has a size such that the end of the page to be turned out of the spread surface of the passbook fits in the lower flat portion 4c.
Although not shown, an optical sensor is provided at a predetermined position to determine the position of the passbook.

Next, a page turning operation according to this embodiment will be described with reference to FIGS. This page turning operation is controlled by a page turning control device (not shown). The page turning control device includes at least the driving roller 7.
The operation of the drive roller 7 and the page changing roller 1 is controlled so as to follow the procedure described below.

The passbook 9 is sandwiched between the transport roller 6 and the drive roller 7, and the front end 9a of the passbook 9 is
Upper boundary 4a with the slope 4b on the downstream side in the transport direction
Is set at a predetermined position just before. At this time, the passbook 9 is held near its binding portion by the transport roller 6 and the drive roller 7, and is held so as not to move (FIG. 3).

In this state, the page changing roller 1 is attached to the passbook 9.
Starts to rotate in a clockwise direction in the figure with a predetermined rotation pattern in order to turn up the page on the front surface.

The cored bar 1b formed of the low friction member of the rotated page changing roller 1 comes into contact with the facing surface of the passbook 9,
The facing surface is pushed down toward the lower flat portion 4c. The passbook 9 is deformed into a primary bending mode with the tip of the convex portion of the slope portion 4b of the transport path 4 as a fulcrum. The passbook 9 is the lower flat part 4
By being pressed against c, an initial deformation is given so as to be in a bow shape, that is, a first-order bending mode before contact with the page turning portion 1a. In addition, flattening is performed, and a bending habit or a curl habit that is a resistance to page turning is corrected.

Of the kinks and curls, those which are likely to cause page turning resistance are, for example, those which are folded or curled in a direction perpendicular to the binding portion. Such bending habits and curling habits are flattened by the cored bar 1b, thereby reducing the page turning resistance.

Further, the shutter 5 for securing a transport space during the passbook transport opens in synchronization with the rotation of the page changing roller 1 (FIG. 4).

When the page changing roller 1 rotates by an arbitrary angle, the page turning portion 1a having a hollow structure comes into contact with the booklet surface page 9b, and when the page changing roller 1 further rotates, the contact point with the booklet surface page 9b becomes the passbook. The page is turned in the direction of the binding section and turned up, and the deformation is further advanced in the already deformed primary bending mode (FIG. 5).

The page turning section 1a of the page changing roller 1
When the user contacts the passbook 9, it is desirable to lower the rotation speed of the page changing roller 1. The reason is that in the case of a high rotation speed, the deformation speed of the booklet paper cannot often sufficiently follow the outermost peripheral speed of the page changing roller 1. In this case, a deformation different from the whole deformation may appear on a part of the paper. A new force for converting the local deformation into the entire deformation is required, and the page turning force from the page changing roller 1 may be insufficient. Therefore, the page change cannot turn the page sufficiently, and a non-pick or a conveyance jam due to the non-pick occurs.

The critical rotation speed at which the pages can be turned over is determined by the material, rigidity, etc. of the page turning portion 1a and the booklet front page 9b.

When the page turning portion 1a is brought into contact with the booklet surface page 9b at a low rotation speed, the bending in the first mode shows a resistance almost equal to the Euler buckling load of the linear buckling analysis, and the page changing roller 1 Then, the user turns over the booklet front page 9b while overcoming the resistance (FIG. 6).

Further, the page changing roller 1 rotates, and the page turning unit 1a further turns the turned page 9b. The turned page comes into contact with the page change guide 3 and its end so that it does not return to the original state even if the contact with the page turning section 1a is released.

The page change guide 3 is made of a member having a low coefficient of friction, and guides the page flipped up due to contact with the end of the page along the end face of the page change guide 3. The turned-up page has a shape that is opposite to the bowed shape when turned up, and the deformation mode changes (FIG. 7).

Further, the driving roller 7 is driven in this state,
The page turning is completed by conveying the passbook 9 in the direction A (FIG. 8).

If the conveying path 4 does not have the inclined surface 4b and the lower flat portion 4c, there is no guarantee that the page subjected to the external force from the page changing roller 1 will be deformed as a whole in the same direction. For example, if the page has a bending habit or a curling habit, the deformation direction of the page is not necessarily limited to the turning direction shown in FIG.
The deformation according to the habit occurs, and in this case, the page is not turned, and there is a possibility that a jam occurs.

FIG. 9 is a side view of a page turning apparatus according to another embodiment of the present invention.

In this page turning apparatus, the lower flat portion 4c is placed on the slope portion 4b and the lower flat portion 4c as shown in FIG.
An elastic thin plate 12 such as a thin plate of rubber or spring steel whose surface is made to have a low friction with fluorine or the like is provided so as to cover the surface. The elastic thin plate 12 reduces the impact force when the page changing roller 1 comes into contact with the bankbook, and bends and deforms due to the force applied to the bankbook 9 from the page changing roller 1. Due to this deformation, it is possible to prevent a large buckling resistance from being generated on the page due to the passbook 9 being bent.

Further, the effect that the occurrence rate of the conveyance jam can be reduced by the above-described concavo-convex shape conveyance path 4 is exerted similarly to the above-described embodiment.

In FIG. 7, when there is a second page turned up together with the page to be turned, the passbook 9 is used in order to shake off the second page.
Is also effective. It is also effective to rotate the page change guide 3 about the rotation axis 8. In the state of FIG. 6, vibration may be applied to the rotation speed of the page changing roller 1 for the above-described reason.

The lower flat part 4c at the tip of the convex part of the slope part 4b
The height h ₁ of from, it is necessary to determine by passbook handling.

[0046] Figure 10 is a diagram showing the relationship between the height h ₁ from the lower flat portion 4c of the convex tip of the embodiment of the page turning passbook page turning success rate and the inclined surface portion 4b by the device. Note that the height from the transport surface of the transport path 4 to the tip of the convex portion is 1.0 mm.

The polygonal line 20 indicates a change in the success rate of turning over a passbook having a thickness of about 0.12 mm and a page number of 10 and having no kinks or curls. In this case, the page can be turned with high certainty.

However, according to the polygonal line 22 showing the change in the success rate of the passbook having a sheet thickness of about 0.08 mm and 18 pages and having no kinks or curls, the height h
_{When 1} becomes 5 mm, the performance drops extremely.

The cause is that the page change roller 1 to the passbook 9
This is due to the direction of the force applied to the surface. In other words, when the step is increased, the inclination of the page to be turned of the passbook 9 when the page changing roller 1 comes into contact with the passbook 9 increases. When performing a page change, it is necessary to apply a force to the page to be turned in the direction of the binding portion of the passbook 9 and in the tangential direction. However, when the step is increased, the inclination of the page to be turned is increased. In addition, it becomes difficult for the page changing roller 1 to apply a force in a tangential direction to a page to be turned. Thus, the step increases, i.e. extremely degraded performance when the height h ₁ is increased. In other words, in consideration of the thickness of the height-h ₁ is handled passbook, it is necessary to set the high range success rate of page turning.

[0050] According to a line 21 which indicates the success rate of the passbook with broken habit a page number 18 pages in thickness 0.08mm about the paper, the success rate when the value of the height-h ₁ is smaller Falls.

When there is no convex portion, since there is no convex portion which triggers the first bending mode for the page to be turned, there is a case where the concave portion 4b is deformed along the inclination. . In particular, a passbook having a curl habit or a folding habit tends to be in this state.

When the passbook is deformed along the slope of the slope 4b as shown in FIG. 11, a bending mode node may be formed at a position corresponding to the slope 4b in the transport path of the booklet front page 9b. Is larger than in the first-order bending mode. At this time, booklet front page 9
b has a drawback that it is difficult to directly enter the primary bending mode, and it is difficult to perform stable page turning.

By providing a conveyed portion with a concave portion and a convex portion as in the present embodiment, deformation along the inclined portion of the conveying path can be avoided, and the above-mentioned problem can be solved. An inexpensive page turning device on which a force acts can be provided.

[0054]
