DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic page break device that changes the pages of a booklet-like medium by rolling page breaks.

[Conventional technology]

There is a media processing device that prints on a booklet-like medium or reads data printed on a booklet-like medium. An example of this is a bankbook entry machine used in financial institutions.

In devices that print or read such booklet-like media, if the printing or reading spans multiple pages, an automatic page break device is used to automatically change pages to improve processing efficiency. will be incorporated.

FIG. 3 is a side view showing an example of a conventional automatic page break device having a page break roller. In the figure, 1 is a page break roller that can rotate in both forward and reverse directions using a motor (not shown in this figure) as a drive source. , 2 is a medium press that moves up and down by a plunger magnet (not shown), 3 and 4 are page break guides, 5 is a medium transport path, 6 to 8 are a pair of transport rollers that are rotated in both forward and reverse directions by a motor (not shown), etc., 9 and 10 are medium position detection sensors each comprising a light emitting element and a light receiving element, and 11 is a page break detection sensor also comprising a light emitting element and a light receiving element.

The medium conveyance path 5 is formed of an upper guide plate and a lower guide plate which are vertically opposed to each other with a predetermined interval, and the page break roller 1 is arranged at a predetermined position on the upper guide plate side.

A page break press 2 that is movable up and down is provided on the lower guide plate side so as to face the page break roller 1, and this page break press 2 enters the medium conveyance path 5 by upward movement and will be described later. The booklet-like medium is pushed up to bring the page break roller 1 into close contact with the booklet-like medium.

Further, the conveyance roller pairs 6 to 8 are arranged along the medium conveyance path 5 at intervals shorter than the length of the booklet-like medium when the pages are opened, and the booklet-like medium is held between the conveyor roller pairs 6 to 8. The medium is conveyed through the medium conveyance path 5.

Further, the medium position detection sensors 9 and 10 are arranged so as to detect the booklet-like medium in the vicinity of the conveyance roller pair 6.7 before and after the page break roller 1, respectively, and the page break detection sensor 11
is arranged above the page break roller 1 so as to detect the page of the booklet-like medium turned over by the page break roller 1.

Furthermore, the page break guides 3 and 4 are provided before and after the page break roller 1 so as to form a part of the upper guide plate, and each of them is connected to a plunger magnet (not shown) with the end of the conveyance roller pair 6.7 as a fulcrum. As shown by the broken line, it rotates upward by approximately 90 degrees and opens.

Next, the operation of the above-described configuration will be explained with reference to FIGS. 4 and 5.

FIG. 4 is a side view showing the page break operation process with the above-mentioned configuration, in which reference numeral 12 is a booklet-like medium, and FIG. (a) to (e) correspond to (a) to (e) in FIG. 4.

First, when the booklet-like medium 12 is sent through the medium conveyance path 5, the booklet-like medium 12 is held between the conveyance path roller pair 6, and is transferred to the conveyance path roller pair 7 by the rotation of the conveyance path roller pair 6. The conveyance path roller pair 7 holds the conveyance path roller pair 7.
Further, it is sent to the conveyance path roller pair 8 side.

At this time, when the booklet-like medium 12 reaches the position of the medium position detection sensor 9, the medium position detection sensor 9 detects this and switches from the OFF state to the ON state.

Then, the leading edge of the booklet-like medium 12 reaches the conveyance path roller pair 8 and is held between the conveyance path roller pair 8, and the booklet-like medium 12 is further conveyed by the conveyance path roller pair 80. When the medium position detection sensor 9 passes, the medium position detection sensor 9 turns OFF from the ON state.
From that point on, the booklet-like medium 12
After conveying the booklet-like medium 12 by a specified distance, the rotation of each pair of conveyance rollers 6 to 8 is stopped to stop conveyance of the booklet-like medium 12.

This process is shown in FIGS. 4(a) and 5(a),
As a result, approximately the center of the page on the left side of the center fold (stitch) of the booklet-like medium 12 is positioned below the page break roller 1.

In addition, at this time, the medium position detection sensor 0 detects the booklet-like medium 1.
2 is detected and switched from the OFF state to the ON state, thereby making it possible to confirm that the booklet-like medium 12 has been conveyed correctly.

Next, the page break guides 3 and 4 are rotated upward and opened by plunger magnets (not shown), respectively.
At the same time, the page break press 2 rises to bring the left page portion of the booklet-like medium 12 into close contact with the page break roller 1, and then the page break roller 1 rotates in the forward direction.

This process is shown in FIGS. 4(b) and 5(b).

Next, the page in contact with the page break roller 1 is turned over by the rotation of the page break roller 1, and when the free end of the turned page reaches the height of the page break detection sensor 11, The page break detection sensor 11 detects this and switches from the OFF state to the ON state, thereby confirming that the page has been turned, and the rotation of the page break roller 1 is stopped.

This process is shown in FIGS. 4(C) and 5(C),
At this time, the turned-up page is in a state leaning against the page feed roller 1.

Next, after the page break press 2 descends and returns to its original position, each conveyance path roller pair 7 to 8 rotates in the opposite direction to the above-mentioned time, whereby the booklet-like medium 12 is transported in the opposite direction.

This process is shown in FIG. 4(d) and FIG. 5(d),
As the booklet-like medium 12 is conveyed, the turned-up stem turns over and falls onto the right side of the booklet-like medium 12 (.

Then, when the page enters the underside of the page break roller 12 and completely falls down, the page break guides 3 and 4 rotate downward and close.

This process is shown in FIGS. 4(e) and 5(e),
This completes the page feed operation.

Incidentally, when performing page breaks for a plurality of sheets, the above-mentioned operation is repeated a plurality of times.

In addition, the center fold (stitch) of the booklet-like medium 12
If you want to change pages on the right side of the border, use booklet media 1
2, the leading edge of which is detected by the medium position detection sensor 10.
After that, the booklet-like medium 12 is transported in the opposite direction, and after the booklet-like medium 12 is transported a specified distance from the time when the medium position detection sensor 10 turns OFF, the transport is stopped. , thereby positioning approximately the center of the right page below the page break roller 1.

The subsequent operations are the same as those described above, except that the page break roller 1 is rotated in the opposite direction, and after the pages are turned up, the booklet-like medium 12 is conveyed in the opposite direction, that is, toward the conveyance roller pair 8 side. By doing this, the page on the right side will be changed to a new page.

[Problems to be Solved by the Invention] However, the above-mentioned conventional automatic page break device has only a page break function, and therefore has the following problems.

In other words, with conventional automatic page break devices, when a page break operation is performed, it is not possible to know whether the target page is open at that time, that is, whether the page break is being performed correctly. Once the booklet-like medium is conveyed to a processing section such as a printing section or a reading section in the next process, the true mark printed in advance on a predetermined position on each page is detected using a page reading sensor installed in the processing section. I am checking whether the page break is done correctly by reading it, but one page break operation results in multiple page breaks, which opens a page other than the intended page. In this case, the booklet-like medium must be fed backwards again to the page break roller position, a page break is performed by reversely turning the pages, and the booklet-like medium is sent back to the processing section again, which increases the processing time. was there.

Conversely, even if you want to make multiple page breaks, the booklet-like medium is conveyed to the processing unit after each page, and the pages are checked and sent back to the page break roller position to start the next page break. Since the target page has to be opened by repeating this operation multiple times, there is also the problem that the processing time becomes long.

The present invention was made in order to solve such problems, and an object of the present invention is to realize an automatic page break device with a page break number detection mechanism that can shorten the page break processing time. .

[Means to solve the problem]

In order to achieve this object, the present invention brings a booklet into close contact with a page break roller disposed on a medium conveyance path, turns the pages of a booklet-like medium by rotation of the page break roller, and frees the pages of the turned page. In an automatic page break device that performs a page break by conveying the booklet-like medium in a direction opposite to the rotational direction of the page-break roller after detecting the end with a page-break detection sensor, the page break roller detects the end of the booklet-like medium a rotatable detection arm disposed such that one end contacts the booklet-like medium due to its own weight on or near an extension of a straight line that is in contact with; a rotation angle detection means for detecting a rotation angle of the detection arm; and a number of page breaks. The apparatus includes a first storage means for storing basic data for detection, a second storage means for storing detection data of the rotation angle detection means, and a determination means for determining the number of page breaks.

[Effect]

The present invention having the above-described configuration includes a rotation angle detecting means that detects the rotation angle of the detection arm when the one end falls from the page to the page below when the page break roller turns over a page of the booklet-like medium. After storing the detection data output from the rotation angle detection means in the second storage means, the determination means combines the basic data for detecting the number of page breaks stored in the first storage means and the first The page break count data stored in the storage means 2 is compared, calculated, or collated to determine how many pages have actually been broken by the page turning operation of the page break roller or the like.

Therefore, according to this, after the page turning operation of the page break roller, etc.
You can know the number of page breaks on the spot without having to send the booklet-like media to the processing unit and read the page marks as in the past.
This allows you to judge whether further page breaks or reverse page turning is necessary, and perform the necessary page break operations until the desired page is opened, reducing the page break processing time. becomes possible.

〔Example] Examples will be described below with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention, in which (a) is a perspective view of a main part, and (c) is a block diagram of a control system.

In FIG. 1(a), a motor 13 serves as a rotational drive source for the page feed roller 1, and the page feed roller 1 is rotated in both forward and reverse directions by the motor 13 via a belt 14.

Note that this page change roller 1 is disposed on the passbook conveyance path as in the conventional case. That is, as shown in FIG. 3, page break guides 3, 4, conveyance rollers 6-8, medium position detection sensor 9.
10 and a page break detection sensor 11, it is arranged together with a page break press 2 on a passbook transport path 5.

A detection arm 5 is supported by the spindle 16 so as to be rotatable about the spindle 16 in a direction perpendicular to the rotational direction of the page break roller 1.
5 is arranged such that one end 15a thereof is in contact with the booklet-like medium 12 on or near the straight line where the page break roller 1 contacts the booklet-like medium 12 due to its own weight, and a retaining bin 15b is placed on the other end. It is provided.

Note that the tip 15a of the detection arm 15 is connected to the booklet-like medium 12.
It is desirable that the shape of the contact portion with the booklet-like medium 12 be in the shape of an arc or a 7-shape as shown in the figure so as not to impede the conveyance of the booklet-like medium 12.

Reference numeral 17 denotes an angle sensor as a rotation angle detection means for detecting the rotation angle of the detection arm 15, 18 a rotatable detection shaft provided on this angle sensor 17, and 19 a retaining piece fixed to this detection shaft 18. , 19a is a guide groove 19a provided in this retaining piece 19, and the pin 15b of the detection arm 15 is slidably engaged with this guide groove 19a. When it rotates around , the rotation is transmitted to the shaft 18 via the bottle 15b and the guide groove 19a, so the shaft 18 rotates, and the angle sensor 17 detects the rotation angle of the shaft 18, that is, the rotation angle of the detection arm 15. A voltage corresponding to the voltage is output.

In FIG. 1 (b), 20 is an amplifier that amplifies the output of the angle sensor 17, and 21 is an A that converts the output of this amplifier 20 into a digital value and outputs it as rotation angle data.
/D converter.

22 is a CPU; 23 is a program memory used as a first storage means for storing a control program for the apparatus and basic data for detecting the number of page breaks; 24 is a rotation output from the A/D converter 21; This is a temporary storage memory serving as a second storage means for temporarily storing corner data, page break number designation data given in advance from a host device, etc. It functions as a control means for controlling the overall operation, and also has a function as a determining means for determining the number of pages to be changed by the page break roller 1.

In this embodiment, the basic data for detecting the number of page breaks stored in the program memory 2 is the rotation angle data corresponding to the rotation angle data when the detection arm 15 rotates by one page of the booklet-like medium 12. Use angle data.

FIG. 2 is a side view illustrating the operation of the tip 15a of the detection arm 15, and the operation of the above-described configuration will be explained with reference to FIG. 2 together with FIG. 1.

Note that since the page feed operation by the page feed roller 1 is performed in the same manner as in the prior art, the operation for detecting the number of page breaks will be mainly described here.

First, the page break press 2 brings the side of the booklet-like medium 12 where the page should be broken (left side of the center fold of the booklet-like medium 12) into close contact with the page-break roller 1, and the tip of the detection arm 15 is placed directly above the page break roller 1. When the page break roller 1 rotates as shown in FIG. 2(a) while the pages 15a are in contact with each other due to their own weight, the page in contact with the page break roller 1 is gradually turned over by the rotation.

As the page is turned up, when the free end of the page passes the tip 15a of the detection arm 15, the tip 15a falls onto the next page as shown in FIG. , whereby the detection arm 15 rotates the support shaft 1 by that amount.
Rotate around 6.

This rotation of the detection arm 15 is controlled by the pin 15b and the guide groove 19.
a, the shaft 18 rotates, and the angle sensor 17 outputs a voltage corresponding to the rotation angle of the shaft 18, that is, a voltage corresponding to the number of pages turned up by the page break roller 1. be done.

The output from this angle sensor 17 is amplified by an amplifier 20 and then input to an A/D converter 21.
The /D converter 21 converts it into a digital value, and outputs it to the CPU 22 as rotation angle data.

The CPU 22 temporarily stores the rotation angle data sent from the A/D converter 21 in the temporary storage memory 24, and reads out this rotation angle data and basic data for detecting the number of page breaks stored in the program memory 23. By comparing or dividing both data, it is determined how many pages have been changed in the page change operation.

Thereafter, the CPU 22 reads out page break designated sheet number data given in advance from a host device or the like and stored in the time storage memory 24, and compares this number with the page break number obtained from the above judgment result.

As a result, if the actual number of sheets of page break is smaller than the number of sheets specified by the page break designation number data, the page on the left side of the booklet-like medium 12 is further changed using the procedure explained in FIGS. 4 and 5. page.

Then, in the same way as described above, the CPU 22 determines how many pages have been broken based on the rotation angle data from the angle sensor 17 due to the rotation of the detection arm 15, and determines whether there is a need for further page breaks. If necessary, repeat the same operation to create the required number of pages.

On the other hand, as a result of comparing the number of pages according to the page break specified number of sheets data and the number of sheets actually page-broken, if the number of sheets actually page-broken is greater than the number of sheets according to the page break specified number of sheets data, the predetermined operation is performed. Accordingly, the page on the right side of the centerfold of the booklet-like medium 12 is brought into close contact with the page break roller 1 by the page break press 2, and the page break roller 1 is rotated in the opposite direction to perform a page break in the opposite direction.

Then, based on the output of the angle sensor 17 due to the rotation of the detection arm 15 accompanying this page break operation, the CPU 22 determines how many pages have been broken, and determines whether there is still a need for page breaks. Repeat the same action further if necessary.

In this way, pages are first changed by the number of sheets specified by the specified page break number data given from the host device or the like.

In the embodiment described above, data corresponding to the rotation angle data when the detection arm 15 rotates by one page of the booklet-like medium 12 is stored in the program memory 23, which is the first storage means, for detecting the number of page breaks. However, a table representing the relative relationship between the rotation angle of the detection arm 15 and the number of page breaks is set in the program memory 23, and the rotation angle data from the angle sensor 17 and the table are stored in the CPU 22. The number of pages changed in one page change operation may be determined by comparing the page numbers.

Further, in the embodiment described above, the page break press 2 is raised to press the booklet-like medium 12 against the page break roller 1 at the time of page break, but the page break roller 1 is made vertically movable.
At the time of page break, the page break roller 1 may be pressed against the booklet-like medium 12 on the lower guide plate to bring it into close contact, and in this way, the page break press 2 can be omitted.

〔Effect of the invention 〕

As explained above, in the present invention, when the page break roller turns over a page of a booklet-like medium, the rotation angle of the detection arm when one end of the detection arm falls from the page to the page below it is determined as the rotation angle. After the detection data detected by the detection means and output from the rotation angle detection means is stored in the second storage means, the determination means combines the basic data for detecting the number of page breaks stored in the first storage means with the detection data outputted from the rotation angle detection means. The data stored in the second storage means is compared, calculated, or collated to determine how many pages have actually been changed by the page turning operation of the page change roller, which is different from the conventional method. After the page break operation by the page break roller, etc., the number of page breaks can be known on the spot without sending the booklet-like medium to the processing unit and reading the page marks, and this allows you to check whether further page breaks are necessary or not. Since it is possible to determine whether reverse page turning is necessary and perform the necessary page break operations until the desired page is opened, the effect of reducing the page break processing time can be obtained. Furthermore, since the number of page breaks can be determined immediately after the page turning operation by the page break roller, fine control is possible and stable operation of the apparatus can be expected.
