Abstract

PURPOSE:To perform the accurate page turning operation by discriminating the turning state of each sheet of paper based on the detection result of a turning detection means to control the operation of a page turning means. CONSTITUTION:A mechanical driving part 13 is operated by the control of a control part 12 to press a turning roll 32 and a retaining rod 33 to sheets of paper (transparent or opaque) of a bankbook P. The turning roll 32 is rotated and driven in the direction of an arrow to turn over a sheet of paper of the bankbook P. When the apex of the sheet of paper intercepts the optical path of an optical sensor 8, the output signal of a photodetector 8b is changed irrespectively of the sheet of paper is transparent or opaque, and the control part 12 controls the mechanical driving part 13 to remove the turning roll 32 from the periphery of the sheet of paper. Thus, the double turning state that the sheet of paper following the sheet of paper to be turned over is erroneously turned over also is prevented, and only one sheet of paper is surely turned over.

Description

Detailed Description of the Invention [Objective of the Invention] (Industrial Application Field) The present invention relates to a page turning device for paper sheets, and more particularly, to a page turning device for paper sheets having a plurality of sheets such as a bankbook. The present invention relates to a page turning device for paper sheets that turns pages.

(Prior Art) A conventional example of this type of page turning device is shown in Figs. 6(a) to (e).
).

Passbook P was brought in with the cover open and spread out,
As shown in FIG. 6(a), it is controlled to stop while being held at one end by the conveyance rollers 31.

From this state, the turning roller 32 with a high friction coefficient
As shown in FIG. 6(b), the presser rods 33 are driven to press against the passbook P by a drive unit (not shown), and further, the flipping reroller 32 is rotated in the direction of the arrow to rotate a specific sheet of the passbook P. is flipped up.

The turning height of this paper sheet is detected by a microswitch 34 in a contact state. At this time, the turning roller 32
If the turning roller 32 is located at the end of the turned sheet and continues to rotate, the turning roller 32 will turn over the next sheet, so the rotation of the turning roller 32 is temporarily stopped.

Next, an arm 35 as shown in FIG. 6(C) is inserted by a drive unit (not shown) into a position that prevents the turned up sheet from returning to its original position. evacuate.

Further, by rotating the arm 35 in the direction of the arrow as shown in FIG. 6(d), the page turning for one sheet is completed.

As shown in FIG. 6(e), a device has also been proposed in which a detection means consisting of a transmitter 36 and a receiver 37 is arranged in place of the microswitch 34 to detect page turning without contact. .

By the way, the turning height of the paper leaf is detected and the turning roller 3
It is important to avoid turning over two or more sheets of paper, but in the case of the conventional device described above, for example, when the turned over sheet is an extremely soft transparent member (transparent sheet), the micro It is extremely difficult to turn on (or turn off) the switch 34.

In addition, a device that detects page turning using only an optical sensor is convenient because it operates without contact, but since light passes through the transparent member, accurate page turning detection cannot be performed.

Furthermore, conventional devices do not determine whether the flipped up paper sheet is a transparent member or not, and as a result, the transparent member attached to it due to static electricity and the adjacent opaque member are turned over together. It also causes some inconvenience.

(Problems to be Solved by the Invention) The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a page-turning device for paper sheets that can perform accurate page-turning operations. be.

[Structure of the Invention] (Means for Solving the Problems) The present invention is a page-turning device for turning the pages of paper sheets having a plurality of sheets and at least one sheet or a portion of one sheet being a transparent member. , a page turning means for turning the pages of each of the sheets; a turning detecting means arranged facing the turning area of the sheet and comprising a transparent member responsive sensor and a transparent member non-reactive sensor; and this turning detecting means. and a determination control means for determining the turning state of each sheet based on the detection result of and controlling the operation of the page turning means.

(for production) The operation of the device having the above structure will be explained below.

For example, when the page turning means of this device turns over a sheet made of a transparent member among the sheets, the detection signal of the transparent member responsive sensor of the turning detection means remains unchanged; The detection signal of the sensor changes.

The determination control means determines that the paper sheet at this time is a transparent member based on changes in the detection signals of both the sensors, and controls the page turning means to perform the next page turning operation.

Further, when the non-transparent member or the non-transparent member and the transparent member are fitted together, the detection signal of the transparent member-reactive sensor changes, and the detection signal of the transparent member-reactive sensor also changes. Thereby, the determination control means determines that the paper sheet at this time includes only a non-transparent member or both a non-transparent member and a transparent member, and controls each page turning means based on the result of this determination.

(Example) Examples of the present invention will be described below.

The page turning device 1 for paper sheets shown in FIGS. 1 and 2 includes a conveyance means 2 for conveying a bankbook P, which is a type of paper sheet, along a conveyance path R, and a conveyance means 2 for detecting the conveyance position of the bankbook P. The conveyance detecting means 3 performs this, the turning detecting means 4 detects the page turning state of the bankbook P, and the turning reroller 32 as the page turning means includes a presser bar 33 and an arm 15.

The conveyance means 2 is arranged above and below the conveyance path R, and
It includes a pair of first and second conveyance rollers 5 and 6 arranged in contact with each other.

The conveyance detection means 3 includes a light emitting element 7a and a light receiving element 7b, and these elements 7a and 7b form an optical path that intersects with the conveyance path R before the first pair of conveyance rollers 5. .

The turning detection means 4 is a transparent member responsive sensor arranged above the conveyance path R facing the turning area of the paper sheet (opaque paper sheet, paper sheet made of a transparent material) formed by the passbook P. It is composed of a sensor 8 and an ultrasonic sensor 9 which is also a transparent member non-reactive sensor.

The optical sensor 8 includes a light emitting element 8a and a light receiving element 8b.

The ultrasonic sensor 9 includes a transmitter 9a that emits ultrasonic waves and a receiver 9b that receives the ultrasonic waves.

Next, the control system of the page turning device 1 will be explained with reference to FIG.

This page turning device 1 is equipped with a control means 10 consisting of a determination section 11 for determining the state of page turning and a control section 12 for overall control. A sensor 8 and an ultrasonic sensor 9 are connected. Furthermore, the control section 12 controls the conveyance of the conveyance means 2 and the mechanism drive section 13 that drives the turning roller 32, presser bar 33, and arm 15.

Next, the operation of the page turning device 1 having the above-mentioned structure is mainly for turning pages of paper sheets made of a transparent member (transparent film) of the passbook P and opaque paper sheets made of paper, etc. Figure (a). (b). This will be explained with reference to (c) as well.

The passbook P conveyed in the direction of the arrow shown in FIG. 1 by the first pair of conveyance rollers blocks the optical path of the conveyance detection means 3, thereby causing a signal change of the light receiving element 7a. The control unit l2 that receives this signal change controls the conveyance means 2 and
is temporarily stopped at the position shown in Fig. 1.

Next, the mechanism drive unit 13 operates under the control of the control unit 12, and as shown in FIG. paper leaf)
Press each.

Next, the reroller 32 is rotated in the direction of the arrow as shown in FIG. 4(b), and the paper sheet of the passbook P is turned over.

When the vertex of the turned-up paper sheet blocks the optical path of the optical sensor 8 as shown in FIG. 4(b), the output signal of the light-receiving element 8b changes regardless of whether the paper sheet is transparent or opaque. As a result, the control section 12 controls the mechanism drive section 13 to retract the turning roller 32 from the vicinity of the sheet.

Thereby, it is possible to prevent the so-called double-turning condition in which the next sheet that is the next page of the sheet to be turned is also turned over.

Next, a mechanism drive unit 13 that operates under the control of the control unit 12
As shown in FIG. 3(C), the arm 15 is inserted into a position that prevents the turned-up sheet from returning to its original position, and the presser bar 33 is retracted.

This ensures that only one sheet of paper can be turned over.

In the above-mentioned sheet turning operation, if the sheet is a transparent member, the optical sensor 8 enters a light transmitting state when the sheet is turned over, and the amount of light input to the light receiving element 8b remains unchanged. Therefore, no change occurs in the output signal of the light receiving element 8b. However, in the ultrasonic sensor 9, the ultrasonic waves do not reach the receiving section 9b due to the presence of the paper sheet, so the output signal of the receiving section 9b decreases.

The output signals of the light receiving element 8b and the receiving section 9b are respectively sent to the discriminating section 12 by the control section l2.

Based on these signals, the determination unit 11 determines that the paper sheet at this time is transparent, and sends a signal to the control unit 1 indicating that the leaf has been successfully turned.
Send to 2.

As a result, the control unit 12 controls the mechanism drive unit 13 to turn up the next sheet.

On the other hand, due to the influence of static electricity or the like, transparent paper sheets and opaque paper sheets may come into close contact with each other and be turned up together.

In this case, the light does not reach the light receiving element 8b of the optical sensor 8 mentioned above, and therefore the output signal of the light receiving element 8b decreases, and the ultrasonic wave does not reach the receiving part 9b of the ultrasonic sensor 9. The output signal of the receiving section 9b also decreases.

At this time, the control unit 12 sends these signals to the determining unit 11, and the determining unit t1 determines that the flipping up at this time is a failure. This determination result is sent to the control unit 12, and the control unit 12 thereby controls the mechanism drive unit 3 to perform retry processing or performs error processing.

As described in detail above, according to the device 1 of the present embodiment, it is possible to automatically determine whether or not the turning of a particularly transparent paper leaf has been successful, and to perform appropriate processing.

After the passbook P has been successfully turned over, it is sent to the next processing section (not shown) by a pair of conveying rollers 5 and 6 that operate under the control of the control section (2).

The present invention is not limited to the embodiments described above,
Various modifications are possible within the scope of the gist.

For example, the arrangement of the optical sensor 8 and the ultrasonic sensor 9 may be reversed to that described above.

Further, the transmitting section 9a and the receiving section 9b of the ultrasonic sensor 9 can be arranged in a reflective manner as shown in FIG.

[Effects of the Invention] According to the present invention described in detail above, with the above structure, paper sheets, including particularly transparent paper sheets, can be reliably turned one by one. A page turning device can be provided.
