Description

TECHNICAL FIELD The present invention relates to a cover-turning mechanism of a passbook printer mounted on an automatic teller machine or the like.

FIG. 4 shows an example of a medium, that is, a passbook used in the passbook printer to which the automatic cover-turning mechanism of the present invention is applied. In the figure, (a) is a plan view of the passbook 1 in an open state,
Similarly, (B) is a side view of the passbook 1 in an open state, and (C) is a plan view of the passbook 1 in a closed state. The passbook 1 is a vertically-opening passbook having a cover sheet 2 and an inner sheet 3, and a printing direction A is parallel to a folding direction B.
On the medium traveling path, the medium is fed in the medium feeding / discharging direction CC '.

When the passbook is inserted into the automatic teller machine in a closed state, the cover of the passbook needs to be automatically turned inside the automatic teller machine in order to print on the inside paper by the printer. Also, when carrying out the processing of carrying over the passbook that has been used on the automated teller machine, in order to issue this passbook after printing the necessary items on a new passbook that has been set in the closed state in advance, You need to flip the cover.

[Conventional technology]

Conventionally, as a mechanism for turning over the cover of a passbook, an attempt has been made to use a mechanism for turning over a middle paper (page turning).

FIG. 5 shows a front view showing the procedure of the work of turning over the front cover by using the mechanism for turning over the inner paper. The passbook 1 provided by rotating a large number of feed rollers 5 arranged along the medium running path 4 in the D direction is positioned at the position shown in FIG. Next, the protruding lever 6 is raised in the E direction to bend the passbook 1 to the state shown in FIG.
Is raised in the F direction to press the vicinity of the end of the passbook 1 against the turning roller 8 with a predetermined pressure. Next, when the turning roller 8 is rotated in the G direction, the cover 2 is separated from the passbook 1 and bulges as shown in FIG. Therefore, the pressure 7 is lowered in the F'direction to release the vicinity of the end of the passbook 1 from the turning roller 8, and the protruding lever 6 is lowered in the E'direction to forcibly bend each leaf other than the cover 2 of the passbook 1. solve. At this time, the cover 2 is still bent due to the frictional force with the turning roller 8, and by further rotating the turning roller 8 in the G direction, the cover 2 is turned as shown in FIG. It is flipped up above the roller 8. When the passbook 1 is fed in the C'direction by stopping the rotation of the turning roller 8 and rotating the feed roller 5 in the D'direction, the cover 2 of the passbook 1 is turned over.

[Problems to be solved by the invention]

In the case of the above-mentioned configuration, since the cover uses a paper much harder than the middle paper, the passbook in the closed state has extremely high bending rigidity as compared with the open state, and thus the fifth pass is used. In order to bend the passbook closed by the protruding lever 6 in the figure (b), a passbook bending mechanism having a strong power source is required. If the power source is made strong, not only is it economically disadvantageous in itself, but the entire passbook bending mechanism becomes large in size, so that it is difficult to provide it in a narrow space along the medium running path.

Therefore, it has been forced to insert the automatic teller machine with the passbook always opened without providing the automatic cover-turning mechanism in the automatic teller machine.

[Means for solving problems]

The present invention provides an automatic cover-turning mechanism that does not use a protruding lever that solves the above-mentioned problems.
A medium traveling path that conveys a medium, a curvilinear curved path that is connected to the medium traveling path, a feed roller that conveys the medium and feeds the medium into the curved path, and a curved path that is provided to sandwich the medium, A pair of curved feed rollers for transporting and fixing, a turning roller that is provided near the boundary between the medium running path and the curved path, and that turns the pages of the medium, and the turning rollers that turn the medium during the page turning operation of the medium by the turning rollers. It is made by an automatic cover-turning mechanism, which is equipped with a pressing force and.

[Action]

The automatic cover-turning mechanism flips the cover using a turning roller and pressure for a medium bent in a curved path in the medium running path, so there is no need to use a protruding lever and a drive mechanism for bending the medium, Therefore, the structure of the cover-turning mechanism can be simplified and the cost can be reduced. Also, in the passbook positioned on the curved path, the base end and the front end of the cover are facing different tangential directions, so that when the cover is raised by the turning roller, an excessive load is not applied to the turning roller and operation is performed. Stabilize.
Therefore, even a cover sheet that is much harder than the middle sheet can be reliably turned over.

Further, during the cover-turning operation, since the medium is in a bent posture in the curved path, page sorting is performed and the reliability of the turning-up operation is improved.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an essential part of an embodiment of the present invention as (a) a longitudinal sectional view and (b) a developed plan view, and FIG. 2 shows the position of the automatic cover-turning mechanism of FIG. 1 in the entire apparatus. A side view is shown. The same parts are denoted by the same reference numerals throughout the drawings. In the figure, an automatic teller machine 9 is provided with a medium running path 4 from the insertion port 10 of a passbook 1 which is a medium, and a feed roller 5 is arranged above and below the medium running path 4. An inserter unit 11 for reading various information of the passbook 1 and a print head 12 along the medium traveling path 4.
And the printing unit 14 including the platen 13 is provided,
An automatic cover-turning mechanism 15 is provided behind the printing unit 14.

In the automatic cover-turning mechanism 15, a part of the medium traveling path 4 is a curved path 16 that bends downward, and a part of the upper wall of the curved path 16 is supported by a hinge 17 so that the movable wall 18 can be freely restrained.
Has become. A turning roller 8 is arranged near the boundary between the medium conveying path 4 and the curved path 16, and an in-curved path feed roller 5'is provided in the curved path 16.
A stopper 19 for blocking the curved path 16 and positioning the passbook 1 is provided behind it.

FIG. 3 is a vertical sectional view showing the procedure of the automatic cover-turning operation using the mechanism shown in FIG. With the turning roller 8 stopped rotating and the pressure 7 descending, the respective feed rollers 5, 5'rotate in the D direction, so that the passbook 1 moves in the medium traveling path 4 in the C direction. To reach Curved Road 16. When the base end portion 20 of the passbook 1 collides with the stopper 19, the rotation of the feed roller 5'in the curved road is stopped and the passbook is positioned, and the pressure 7 rises in the F direction to move the passbook 1 near the tip portion 21 thereof. Press it against the turning roller 8. Next, the turning roller 8 rotates in the G direction.

In this case, μ ₁ = coefficient of friction between the surface of the turning roller 8 and the cover 2 of the passbook 1 μ ₂ = coefficient of friction between the cover 2 of the passbook 1 and the inside paper F ₁ = pressure 7 presses the passbook 1 against the turning roller 8. Pressure pressure F ₂ = Rigidity of cover 2 F ₃ = Rigidity of middle paper, under the conditions of F ₂ > F ₃ , conditions are set so that μ ₁ >> μ ₂ and the value of F ₁ is set to the appropriate pressure. By adjusting to, μ ₁ F ₁ > F ₂ > F ₃ > μ ₂ F ₁ (1) Equation (1) can be satisfied. When the formula (1) is satisfied, only the cover 2 can be separated from the passbook 1 by the rotation of the turning roller 8 and expanded as shown in FIG. The load applied to the cover 2 by the movable part 18 is sufficiently small.

When the sensor (not shown) detects that the cover sheet 2 is raised to the state shown in FIG. 3B, the pressure 7 is lowered in the F'direction to prevent the two sheets from being turned over, and the turning roller 8 is continuously rotated in the G direction. To do.

When the cover sheet 2 is flipped up above the turning roller 8 as shown in FIG. 3C, this state is detected by a sensor (not shown) and the rotation of the turning roller 8 is stopped. Next, when the feed roller 5 rotates in the D'direction, the passbook 1
Are fed in the C'direction and the front cover 2 is turned over.

As described above, since the cover sheet is turned in the state that the passbook is bent at the curved portion 16, the cover sheet can be surely turned without the need for a protruding lever or the like.
Moreover, since the direction of the base end portion 20 of the passbook 1 or the portion of the passbook sandwiched between the feed rollers 5'in the curved road and the direction of the vicinity 21 of the leading end of the passbook 1 are different, the feed roller 5'in the curved road The force required to put the passbook 1 in such a bent state is as compared with the case where the center portion of the passbook is pushed up by the protruding levers while holding both ends of the passbook in the same direction as shown in FIG. A small amount is enough.

〔The invention's effect〕

As described above, according to the present invention, since the cover is turned over in a state where the passbook is bent in a curved path, the projecting lever is not used and a strong power source for bending operation is not used.
The cover can be surely turned over, the mechanism can be simplified, and the cost can be reduced.
