DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of separating a middle sheet when turning a middle sheet of a passbook or the like in an automatic page breaking mechanism such as a passbook certificate issuing machine used in a financial institution or the like.

[0002]

2. Description of the Related Art Conventionally, in an automatic page-breaking mechanism, for example, a page-break roller is pressed against a center sheet of a passbook to be broken, and the page-break roller is rotated to turn the middle sheet to perform a page break. . When turning the inner sheet, a plurality of sheets may be stacked and turned up. In such a case, it is necessary to separate the uppermost sheet. FIG. 9 is an explanatory view showing a conventional automatic page break mechanism, which will be described below with reference to the drawings.

In FIG. 9, a passbook 1 is conveyed to a page turning position by feed rollers 2a, 2b, 3a and 3b in a double-page spread state. Above the inner sheet 4 to be turned of the passbook 1,
Movable guide plates 5 and 6 are provided, and a page break roller 7 is rotatably disposed on the right side thereof. A feed roller 8 is disposed so as to face the page break roller 7 and sandwich the passbook 1. The feed roller 8 is moved toward and away from the passbook 1 by driving means (not shown). Above the middle sheet 4, detection sensors 9, 1 for detecting that the middle sheet 4 has been turned up
0 is arranged. Each of the detection sensors 9, 10 includes a light emitting element 9a, 10a and a light receiving element 9b, 10b.

[0004] Next, the operation of separating the inner sheet in the page break operation of the above-described conventional mechanism will be described with reference to the operation explanatory diagrams of FIGS.

First, the movable guide plate 6 is opened in the direction of the arrow by a drive source (not shown) to a position shown by a solid line, and the space above the inner paper 4 of the passbook 1 is opened. Next, the page feed roller 7 is reciprocally rotated alternately in the directions of arrows A and B. At this time, if the rotation amount in the A direction is a and the rotation amount in the B direction is b, a
> B. When this reciprocating rotation is repeated several tens of times, the page break roller 7 moves in the direction indicated by the arrow A by the ratio difference (ab).
As shown in FIG. 9, the inner paper 4 is gradually lifted up. Such a small reciprocating rotation of the page feed roller 7 promotes the separation of the middle sheet when a plurality of the middle sheets are stacked and lifted.

When the lifted inner sheet 4 is detected by the detection sensor 9 (FIG. 10), the feed roller 8 is lowered,
Move away from bankbook 1. This further promotes the separation of the inner sheet.
The page feed roller 7 is still reciprocating, and when the inner sheet 4 is detected by the detection sensor 10 (FIG. 11), the reciprocating rotation of the page feed roller 7 is stopped.

Next, the page break roller 7 is rotated in the direction of arrow B,
The middle paper 4 is returned by a fixed amount (FIG. 12). This further promotes the separation of the inner sheet. After returning by a certain amount, the page break roller 7 is rotated in the direction of arrow A, and the inner paper 4 is flipped up (FIG. 1).
3). In this state, the feed rollers 2a, 2b, 3a,
3b, the passbook 1 is moved in the direction of arrow C shown in FIG.

[0008]

However, in the above-mentioned conventional method for separating middle sheets, there is a problem that the separation of a plurality of middle sheets wound up simultaneously due to friction between the middle sheets or static electricity is not sufficiently performed. was there.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to return a middle sheet lifted to a certain height by a certain amount, and then lift it up to the certain height again, and then flip it up. By doing so, it is possible to improve the separation of the inner sheet and to eliminate the occurrence of errors due to multiple turns.

[0010]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to press a page-break roller against a middle sheet of a booklet-shaped medium,
In the middle sheet separation method of turning the middle sheet by rotating the page break roller and separating the wound middle sheet one by one by the above-described sheet break roller, the middle sheet is fixed by rotating the page break roller in one direction. The inner page is returned by a certain amount by lifting up to the height and making small reciprocating rotations with the amount of rotation in the other direction slightly greater than the other direction, and then rotating the page break roller in one direction than the other direction. The middle paper was lifted to the above-mentioned fixed height by slightly reciprocating rotation with a slightly increased amount, and then the page break roller was rotated in one direction to jump up the middle paper.

[0011]

According to the present invention having the above-described structure, the inner sheet once lifted to a certain height is reciprocated in small increments by rotating the page-break roller slightly in the other direction than in one direction. Return a certain amount. At this time, the inner paper that has been lifted together by static electricity or the like is promoted to be separated. After being returned by a certain amount, the inner sheet is lifted again to a certain height by rotating the page break roller in small increments of reciprocating rotation slightly larger in one direction than in the other direction, and also separated at this time. Is prompted. As described above, the separation of the inner sheet is performed favorably. Therefore, the occurrence of errors due to multiple turns is reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments according to the present invention will be described below in detail with reference to the drawings. Elements common to the drawings are assigned the same reference numerals. FIG. 1 is a flowchart showing a method for separating a middle sheet according to an embodiment of the present invention, and FIG. 2 is a block diagram showing a control system of an automatic page break mechanism of the embodiment. The structure of the automatic page break mechanism in this embodiment is the same as that of the conventional example shown in FIG. 9, and therefore, the description thereof is omitted, and the control system will be described here.

In FIG. 2, a main control section 11 controls the operation of the entire apparatus. A page break operation control circuit 12 connected to the main control unit 11 controls the page break operation. The page feed roller drive motor drive circuit 13 drives a page feed roller drive motor 14. The passbook transport motor drive circuit 15 drives a transport motor 16 that transports the passbook. The page mark matching circuit 17 checks the page mark printed on the passbook, and the page mark / line information recognition circuit 18 recognizes the page mark and the print line of the passbook. Page mark / line information detection circuit 1
9 detects a page mark and line information based on the output of the reflection sensor 20 and outputs it to the page mark / line information recognition circuit 18.

The passbook position detecting circuit 21 detects the position of the passbook based on the output of the passbook position detecting sensor 22. The inner sheet detection circuit 23 detects the turning-up of the passbook based on the outputs of the detection sensors 9 and 10.

FIG. 3 is an explanatory diagram for explaining the middle sheet separating operation of the embodiment. In FIG. 3, the feed roller 2
a, 2b, 3a, 3b and 8 are driven by a passbook transport motor 16, and the page feed roller 7 is a page feed roller drive motor 1
4.

Next, the separation operation of the inner sheet according to the present embodiment will be described with reference to the flowchart of FIG. 1 and FIGS.
FIG. 4 to FIG. 8 are explanatory views for explaining the middle sheet separating operation of the embodiment. The operation described below is controlled by the main control unit 11 and the page break operation control circuit 12 shown in FIG.

Prior to the page break operation, the passbook 1 is sandwiched between the page break roller 7 and the feed roller 8 at the page break position with the middle sheet 4 to be broken. In this state, a page break operation is started.

First, the movable guide plate 6 is opened in the direction of the arrow shown in FIG. 3 by a motor (not shown). Next, the page feed roller 7 is rotated forward, that is, rotated in the direction of arrow A by the page feed roller drive motor 14 (step 1). Thereby, the inner paper 4 is gradually lifted. Inner paper 4 by detection sensor 9
Is detected (Step 2), the feed roller 8 is turned off (Step 3), and the feed roller 8 is separated from the passbook 1 as shown in FIG. By separating the feed roller 8, separation of the inner sheet 4 that has been simultaneously wound up is promoted.

When the inner sheet 4 is further lifted and reaches the height of the detection sensor 10 (FIG. 5), it is detected by this sensor 10 (step 4), and the page feed roller 7 is alternately moved in the directions of arrow A and arrow B. (Figure 6). At this time, assuming that the rotation amount in the A direction is a and the rotation amount in the B direction is b, the rotation is performed at a ratio of a <b (step 5). By repeating this reciprocating rotation several tens of times, the rotation is gradually performed in the direction of the difference (ba) B in the rotation amount, and the inner sheet 4 is returned by a fixed amount. This fixed amount is set based on the difference between the rotation amounts and the number of reciprocating rotations. The small reciprocating rotation of the page feed roller 7 promotes separation of the inner paper 4 that has been simultaneously wound up, especially the inner paper 4 that is stuck by static electricity. In FIG. 6, reference numeral 4 a denotes a middle sheet that is attached to the middle sheet 4 to be broken and separated here.

When the inner sheet 4 is returned by a fixed amount (step 6), the page feed roller 7 is reciprocated at the ratio of a> b (step 7). Thereby, the inner sheet 4 is lifted again.
Also at this time, separation of the inner sheet 4 is promoted. Then, as shown in FIG. 7, when the detection sensor 10 detects the inner sheet 4 (step 8), the reciprocating rotation of the page feed roller 7 is stopped, and the page feed roller 7 is rotated in the direction of arrow A so that the inner sheet 4 is moved. Jump up (step 9). In this state, the feed rollers 2a, 2b, 3
The passbook 1 is moved in the direction of arrow C shown in FIG.

[0021]

As described above in detail, according to the present invention, the inner sheet lifted to a certain height by the page feed roller is returned by a predetermined amount by repeating the small reciprocating rotation of the page feed roller, and then lifted up again. Since the sheet is flipped up later, the separation of the plurality of inner sheets turned up at the same time is favorably promoted, and an error caused by multiple turns can be prevented.
