A passbook sending mechanism for returning the completed passbook to the passbook insertion slot is incorporated. As this kind of passbook feeding mechanism, for example, there is one using a transport guide as shown in FIG. 6 (see Japanese Patent Application Laid-Open No. H10-162203).

Referring to the transport guide shown in FIG. 6, a passbook transport path 22 is formed by a pair of opposing plate-like transport guide bodies 20, 21, and a passbook is inserted at the base end of the insertion transport path 22. It is connected to the passbook insertion slot. A plurality of pairs of upper and lower roller shafts 23 and 24 are incorporated at predetermined intervals along the passbook conveying direction on the surface of the pair of plate-like conveying guide bodies 20 and 21 opposite to the surfaces facing each other. The passbook is conveyed by these roller shafts 23 and 24.

One of the roller shafts 23 and 24 (for example, the lower roller shaft 24 in the figure) is used for driving, and the other (for example, the upper roller shaft 23 in the figure) is used for tension. The driving roller shaft 24 has a plurality of driving rollers 25... Mounted on the supporting shaft 24 a at predetermined intervals along the axial direction, and the supporting shaft 24 is forcibly driven by a motor (not shown). By being rotated, the rollers 25 are rotated in forward and reverse directions.
On the other hand, the tension roller shaft 23 has a plurality of tension rollers 26 attached to the support shaft 23a at predetermined intervals along the axial direction, similarly to the drive roller shaft 24. . Further, the tension roller shaft 23 is not structured to be forcibly rotated,
Instead, both ends of the support shaft 23a are springs 2 respectively.
7, 27 are pressed against the driving roller shaft 24 side.

[0005] The plate-like transport guide bodies 20, 2
1 has a plurality of roller insertion openings 20a,.
Are formed, and a part of each of the driving roller 25 and the tension roller 26 is protruded from the roller insertion openings 20a and 21a so as to be opposed to and contact with each other.

In this transport guide, the passbook is sandwiched between the driving roller 25 and the tension roller 26, and in this state, the driving roller 25 is rotated in a predetermined direction to automatically enter the machine. Be drawn in. The completed passbook is automatically returned to the passbook insertion port by rotating the driving roller 25 in the opposite direction.

[0007]

The above-mentioned conventional transport guide has the following problems. The tension roller shaft 23 is a single roller shaft 23.
a, a plurality of tensioning rollers 26 are attached to the roller shaft 23a, and a tension is applied by a spring 27 on both sides of the roller shaft 23a. Only a small tensile force is applied to the tension roller 26, and the tensile forces applied to the tension rollers at both ends and the center tend to be different. For this reason, there has been a problem that the passbook as the object to be conveyed may not be accurately conveyed.

At first glance, the conventional transport guide looks as if the replacement of the tension roller shaft 23 is easy.
Is replaced, the newly installed tension roller 2
There is a problem that the running cost is increased because it takes time to adjust the pressurizing force of No. 6 and skill is required for the rearrangement and adjustment.

The tension roller shaft 23 is required to have a straight shape at the time of assembling and to avoid deformation such as bending during use, and also to be relatively lightweight. . In consideration of these conditions, it is advantageous to use a quenched shaft, but if quenching is performed, it becomes distorted, so straightening work or the like is required to straighten the shaft. Even when a shaft is used, there is a problem that a significant increase in cost cannot be avoided.

Even if one of the plurality of tension rollers 26 attached to the tension roller shaft 23 is damaged, the entire tension roller shaft must be replaced, which is uneconomical. Was.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a transport guide according to the present invention and a roller unit assembled to the transport guide.

FIG. 1 is an enlarged view of a main part of a transport guide according to the present invention. In this figure, reference numerals 1 and 2 denote plate-shaped conveyance guide bodies forming a pair, and a driving roller 3 and a tension roller 4 are incorporated in the upper and lower plate-shaped conveyance guide bodies 1 and 2, respectively. And
The rollers 3 and 4 constitute a transport guide A for transporting a transport object such as a passbook.

As shown in FIG. 3, a plurality of roller insertion ports 2a are formed in the lower plate-shaped conveyance guide body 2, and the tension rollers 4 are provided in these roller insertion ports 2a.
It is incorporated in the form of a roller unit 5. The tension roller 4 in the roller unit 5 includes the upper plate-shaped transport guide body 1 on the opposite side to the lower plate-shaped transport guide body 2 on which the tension roller 4 is assembled by the coil spring 7, that is, It is urged toward the driving roller 3 and is capable of retreating in a direction opposite to the urging direction. In FIG. 3, reference numeral 8 denotes a paper guide formed so as to protrude from the plate-shaped transport guide main body 2 for transporting an object to be transported such as a passbook in a normal posture without swinging left and right.

A plurality of the driving rollers 3 are attached to the support shaft 3a at predetermined intervals along the axial direction, similarly to the above-described driving roller 25 shown in FIG. 6, and are integrally formed with the support shaft 3a. It is forcibly rotated in the forward and reverse directions by a motor (not shown).

The roller unit 5 includes a housing 10 inserted into the roller insertion opening 2a of the plate-shaped conveyance guide body 2 in an inserted state, and left and right sides 11, 1 of the housing 10.
A shaft 13 movably supported in the long hole 12 formed in the first hole 1 along the longitudinal direction of the long hole 12, the tension roller 4 supported by the shaft 13, and the housing 10 and the shaft 13. Shaft 1 interposed in
And the coil spring 7 for urging the long hole 3 along the long axis direction of the long hole 12.

The housing 10 is formed in a box shape with an open top so that the tension roller 4 is housed therein, and one of the peripheral sides is outward. The coil spring storage portion 15 is formed to extend. A flange 16 is formed at the upper end of the left and right sides 11, 11 of the housing 10 to protrude outward.
2), the flange portion 16 is
When 0 is inserted into the roller insertion opening 2a of the plate-shaped conveyance guide body 2 in an inserted state, it serves as a locking portion that is locked by the roller insertion opening 2a (see FIG. 1). When the housing 10 is mounted in the roller insertion opening 2a in an inserted state, the upper surface of the distal end of the coil spring storage portion 15 contacts the lower surface of the plate-shaped conveyance guide body 2 (see FIG. 1).

The shaft 13 is, as shown in FIG.
Both sides are formed to have a substantially elliptical cross-section that is flattened off, and the upper surface and the lower surface at the center are each formed in an arc shape bulging outward. Also, shaft 1
Locking grooves 13a, 13a are formed on the lower surfaces of both ends of 3 and the extension 7c of the coil spring 7 is locked in the locking grooves 13a, 13a (see FIGS. 1 and 4).

The tension roller 4 is a cylindrical roller having an appropriate radius, and has a through hole formed in the center thereof through which the shaft 13 passes. A material having a large coefficient of friction such as rubber is adhered to the surface of the tension roller 4 or the driving roller 3 as necessary.

The coil spring 7 is bent into a U-shape at the center, and has a locking portion 7a which is locked in a locking hole 15a formed in the front surface of the coil spring storage portion 15 of the housing (FIG. 1). 1, see FIG. 4), coil portions 7b, 7b wound on opposite sides on both sides thereof, and extension portions respectively linearly extended from the coil portions 7b, 7b so as to be substantially perpendicular to the axis of the coil. 7c, 7c. A shaft 17 supported and attached to the coil housing 15 of the housing 10 passes through the center of the coil spring 7.

The coil spring 7 is prepared in advance with various spring loads, and a plurality of shaft rods 17 are also prepared in different colors according to the load of the coil spring 7. And the coil spring and the shaft 17
Is assembled into the coil unit 5 in a pair with
The load of the coil spring 7 used can be understood only by looking at the color 7. The housing 10, tension roller 4, shaft 13, shaft 17
Are made of resin in consideration of cost and weight reduction, respectively.

Next, the operation of the transport guide having the above configuration will be described. When, for example, a passbook, which is an object to be conveyed, is conveyed to the conveyance guide A and reaches between the driving roller 3 and the tension roller 4, a sensor (not shown) detects the fact and outputs an output signal. Based on this, a signal is issued from a controller (not shown), and the driving roller 3 is forcibly rotated in a predetermined direction by a motor (not shown) based on the signal, whereby the passbook is drawn into the machine. After that, after the passbook is filled in the machine, the driving roller is rotated in the opposite direction to the above, so that the passbook is returned in the insertion direction opposite to the above.

Here, the tension roller 4 is provided with a plurality of roller insertion openings 2a provided in the plate-shaped conveyance guide body 2.
In the form of roller units 5, they are individually assembled in a state where they are individually urged toward the upper driving roller 3 by coil springs 7. Therefore, in the transport guide A, a plurality of tension rollers 4 are incorporated along the length direction of the shaft 13 and the transport direction, respectively. However, the urging force of the tension rollers 4 toward the drive roller 3 is small. For example, the same value can be set by using the coil spring 7 having the same spring load.

Therefore, as described in the prior art,
Although a large tensile force is applied to the tension rollers 26 at both ends, only a small tensile force is applied to the tension roller 26 at the central portion, and it is possible to avoid a situation in which a passbook or the like cannot be accurately conveyed. Can be transported.

Further, as described above, the tension roller 4
Are individually biased by the coil springs 7, so that, for example, it is possible to freely adjust a part of the coil spring 7 or set a part of the coil spring to a weak spring load. it can. That is, the urging force of the tension roller 4 on the center side of the transport guide A can be set to be stronger than that of the tension rollers 4 on both sides, and vice versa. It is also possible to set the urging force of the tension roller 4 on the center side weaker than that of the tension rollers 4 on both sides.

Further, when the tension roller 4 is damaged, only the damaged roller 4 can be easily replaced, which is advantageous from the viewpoint of running cost.

When the passbooks or the like are transported, even if the thickness between the passbooks to be transported changes, or the thickness of the location where the tension roller 4 hits during the transport of one passbook changes. However, the shaft 13 can be freely moved along the long axis direction of the long hole 12 formed in the housing 10 accordingly, so that the biasing force of the upper and lower drive rollers 3 and the tension roller 4 to the passbook is substantially reduced. It is kept constant, and the passbook can be transported accurately from this point.

In addition, since the upper and lower surfaces of the center of the shaft 13 are formed in arcs bulging outward, the tension roller 4 comes into contact with the shaft 13 at points. Therefore, the shaft 13
The friction between the tension roller and the tension roller 4 is reduced, and the tension roller rotates smoothly. Further, since the tension roller 4 can swing right and left, even when the tension roller receives a moment such that the tension roller touches the right and left due to the contact surface with the passbook, the tension roller 4 moves in that direction accordingly. Swing is possible, and also in this point, the object to be conveyed can be smoothly conveyed.

Also, since the various coil springs 7 having different spring loads and the shaft rods 17 of which colors are changed in accordance with the coil springs are incorporated in the coil unit 5 in advance, the shaft rods 17 are provided.
The color of the coil unit 7 can be easily determined simply by looking at the color of the coil unit 5. Therefore, it is easy to cope with a case where the spring load needs to be increased a little for maintenance or a case where the spring load needs to be reduced slightly. it can.

The extension 7 of the coil spring 7
c engages with locking grooves 13 a at both ends of the shaft 13, whereby the coil spring 7 urges the tension roller 4 via the shaft 13 toward the driving roller 3, and 13 is also prevented from falling out of the housing 10. That is, the coil spring 7
Is not limited to merely urging the tension roller 4 in a predetermined direction, and also serves to prevent the shaft 13 from coming off.

Further, in the housing 10, a flange portion 16 is formed at the upper end of both sides 11 supporting the shaft 13 so as to be engaged with the roller insertion opening 2a of the plate-shaped conveyance guide body 2. Opening 2a of the plate-shaped transport guide body 2 near the portion supporting the shaft 13 as shown in FIG.
Since the locking portion (flange portion) is provided, the shaft 13 can be supported by a relatively strong force, and the tension roller 4 can be smoothly rotated in this point as well.

In the above embodiment, the transport guide A assembled to the ATM has been described as an example. However, the transport guide A and the roller unit 5 according to the present invention are not limited to the ATM. Of course, it is also possible to use by being assembled to another device. Further, in the above-described embodiment, the metal coil spring 7 is used as a member for urging the tension roller 4, but another member such as a resin coil spring may be used instead. Alternatively, a resin plate may be used.
