FIG. 1 shows an embodiment of the present invention and shows the width-shifting device 30 described above. 31 is the first clamping means,
Reference numeral 32 is a second clamp means.

A pair of clamp arms, an upper clamp arm 33 and a lower clamp arm 34, is attached to the first clamp means 31 on a slide bracket 35 so as to be rotatable about a shaft 36, respectively.

A guide roller 37 is rotatably attached to each of the clamp arms 33 and 34, and a friction member 38 is fixed to each of the tip ends thereof, so that a medium 39 such as a passbook or a certificate can be sandwiched. The clamp spring is configured to engage with a constant force.

The slide bracket 35 and the rack 40 are slidable in the horizontal direction, and both slide while being pressed against each other by the spring 41.

When the slide bracket 35 moves in the horizontal direction, the upper and lower guide rollers 37 rotate along the plate cam 42, whereby the upper and lower clamp arms 33,
34 sandwiches or separates the medium 39.

The lower part of the rack 40 is an idle gear 43.
The idle gear 43 is connected to a motor gear 45 fixed to the motor 44.

When the motor 44 is driven and the motor gear 45 rotates in the direction of arrow A, the upper and lower clamp arms 33,
34 moves in the direction of arrow A ', and the motor gear 45 moves in the direction of arrow B.
When rotated in the direction, the upper and lower clamp arms 33 and 34 move in the arrow B'direction.

Home position sensor (HP sensor) 46
Is a switch such as an optical sensor, a micro switch, or a pressure sensor, which is used to manage the rotation amount of the motor 44 and set the origin position when the power is turned on.

The detection sensor 47 is for detecting whether or not the medium 39 is attracted to the reference surface 48, and is provided at a position slightly apart from the reference surface 48, and when the detection sensor 47 is turned on, the width adjustment is performed. It is determined to be OK.

The HP sensor 46 and the detection sensor 47 are optical sensors composed of a light emitting element and a light receiving element in this embodiment, and will be described as ON when the optical axis from the light emitting element is blocked.

A pair of upper and lower guide members 49 for regulating the front and back positions of the medium 39 form a conveying path for the medium 39, and hold the medium 39 together with the pressure contact portion 50 of the second clamp means 32.

The pressure contact portion 50 presses the medium 39 with a weak force, but the load in the pulling direction due to the medium pushing force is weaker than the pulling force of the first clamp means 31, and the tip portion thereof does not hinder the conveyance of the medium 39. Thus, it is configured in a round shape such as a hemisphere or a narrow roller shape.

The slide bracket 35,
The rack 40, the idle gear 43, the motor 44, the HP sensor 46, etc. are attached to the frame 51.

FIG. 4 is a flow chart of the width-shifting operation of the embodiment of the present invention, FIG. 5 is a diagram showing the relationship between the rotation of the motor and the specified movement amount of the clamp arm, and FIG. 6 is the width-shifting operation of the embodiment of the present invention. FIG.

As shown in FIG. 6 (I), first, the medium 39 clamped by the roller pair 15 (which will be described below in the example of the passbook) is separated from the reference surface 48 by a magnetic stripe read / read. It is conveyed to the light unit 16.

At this time, the upper and lower clamp arms 33 and 34 are open, the rack 40 is at a predetermined position, and a part of the rack 40 blocks the optical axis of the HP sensor 46. Therefore, the HP sensor 46 is in the ON state.

As shown in FIG. 1, when the motor 44 is rotated in the direction of arrow B to perform the width-shifting operation (step S1), the upper and lower clamp arms 33 and 34 are integrated with the slide bracket 35 and the rack 40. Then, the HP sensor 46 is switched off (S2).

When the motor 44 is rotated by a prescribed amount in this state, the upper and lower clamp arms 33, 34 move by the prescribed amount K1 shown in FIG. 5, and the friction member 38 as shown in FIG. 6 (II).
The passbook 39 is sandwiched by (S3).

Further, by a magnet or the like not shown, the lower roller of the roller pair 15 is separated from the passbook 39 to be in a clamp-off state, and the passbook 39 is set in a free state.

At this time, the passbook 39 is clamped by the upper and lower clamp arms 33 and 34 which are the first clamp means, and the pressure contact portion 50 of the second clamp means 32 is conveyed by the conveying path 6.
The passbook 39 is pressed into contact with the upper guide member 4 by projecting inward.
Since the passbook 39 is sandwiched between 9 and 9, it does not slide down the transport path 6 (S4).

From this state, the motor 44 is further rotated to move the upper and lower clamp arms 33 and 34 by the specified amount K2 in FIG. 5, and the motor 44 is stopped (S5).

At this time, as shown in FIG. 6 (III), the passbook 39 is sandwiched between the upper and lower clamp arms 33 and 34, drawn toward the reference plane 48, and abuts against the reference plane 48. At this point, the slide bracket 35 does not move and the rack 4
Only 0, overcomes the force of the spring 41 and moves a specified amount.

Next, the roller pair 15 is clamped on by a magnet or the like (not shown), and the press contact portion 50 is retracted to the outside of the conveying path 6 accordingly (S6).

When the detection sensor 47 shown in FIG. 6 is turned on, it is determined that the passbook 39 has been drawn to the reference surface 48, and the width adjustment is OK (S7).

Next, the motor 44 is rotated in the direction of arrow A shown in FIG. 1 (S8), and after the HP sensor 46 is turned on (S8).
9), the upper and lower clamp arms 33 and 34 are moved by the specified amount K3 shown in FIG. 5, and the motor 44 is stopped (S10).

The state at this time is as shown in FIG.
The passbook 39 is brought into contact with the reference surface 48, and the width-shifting state is completed.

On the other hand, in step S2, the HP sensor 4
When 6 is on, the process returns to the beginning and the motor 44 is rotated in the direction of arrow B.

In step S7, the detection sensor 4
If 7 is not turned on, the width adjustment is insufficient. Therefore, it is determined whether or not a retry operation for width adjustment is necessary (S11), and the operations of S1 to S7 are performed until N times of operations are executed. Repeat.

Although this retry operation is shown as N times in FIG. 4, it normally ends after about 3 times, and an error occurs when the detection sensor 47 still causes imperfect alignment.

FIG. 7 is a plan view showing the positional relationship of the width adjustment, with respect to the clamp arms 33 and 34 of the first clamp means.
The pressure contact portion 50 of the second clamp means is arranged substantially on its extension line. The size of the medium 39 to be used is determined so that it can be pinched even with the smallest size.

With this arrangement, the medium 39 can be supported at two points, that is, the friction member 38 and the pressure contact portion 50, when the medium 39 is moved toward the reference surface 48 as indicated by the alternate long and short dash line.

8 and 9 are sectional views taken along the line CC of FIG. 7 showing an embodiment of the second clamping means of the present invention.

FIG. 8 shows that when the roller pair 15 is clamped off,
FIG. 9 shows the state when the clamp is on.

Here, the roller pair 15 will be described by distinguishing between the upper feed roller 15a and the lower pressure roller 15b.

The press contact portion 50 is fixed to the tip of the push shaft 61. The push shaft 61 is slidably supported in a direction orthogonal to the transport path 6, but the supporting means is not shown.

Reference numeral 62 denotes a spring, the position of which is regulated by a stopper ring 63 which is inserted into the push shaft 61 and whose upper end is the lower surface of the press contact portion 50 and whose lower end is fixed to the push shaft 61.

Reference numeral 64 is a reset spring, which applies tension in the direction of arrow D shown in the figure.

Reference numeral 65 is a push lever having a tip end that abuts on the stopper ring 63.

The push lever 65 is rotatably supported by a rotation fulcrum 66, and the rotation fulcrum 66 is supported by a frame (not shown).

Reference numeral 65a is a substantially U-shaped engaging portion provided at the other end of the push lever 65.

Reference numeral 67 is an arm fixed to the pressure roller shaft 69, and the post 67a at the tip thereof is the engaging portion 6.
5a is fitted.

Reference numeral 68 denotes a pressure roller arm that rotatably supports the pressure roller 15b, and is rotatable in the directions of arrows E and F by the rotation operation of the pressure roller shaft 69. Further, by a known technique (not shown), a constant pressure can be applied to the feed roller 15a.

The pressure roller shaft 69 is rotatably supported by a frame (not shown) and is rotated by a predetermined angle by a drive source (plunger magnet etc.) not shown.

Next, the operation will be described. In FIG. 9, when the pressure roller shaft 69 is rotated by a predetermined angle by a drive source (plunger magnet or the like) not shown in FIG. 9, the pressure roller arm 68 rotates in the direction of arrow E. By the operation, the pressure roller 15b comes into pressure contact with the feed roller 15a.

The arm 67 is rotated by the rotation of the pressure roller shaft 69, and the push lever 65 is rotated clockwise.

The push shaft 61 moves in the direction of the arrow D by the tension of the reset spring 64, and the pressure contact portion 50 retreats from the transport path 6 so that the transport operation of the medium 39 is not hindered.

In FIG. 8, when the driving source (not shown) is turned off, the restoring force (not shown) restores the pressure roller 15b.
Moves away from the feed roller 15a.

At the same time, when the arm 67 rotates, the push lever 65 rotates counterclockwise and the push shaft 63 rotates.
Is pushed up, and the medium 39 is sandwiched between the medium 39 and the upper guide member 49 constituting the transport path 6.

The spring 62 is compressed by this pushing-up force, and this force is applied to the pressure contact portion 50 to become the medium pressing force.

[0074]

As described above in detail, according to the present invention, the medium is supported at two points by the first clamping means and the second clamping means at the time of width-shifting. There is an effect that is prevented from rotating due to the action of gravity to slide down the transport path and shift its position.

Further, when it is used in the horizontal conveyance path, it is possible to stabilize the width-shifting operation.
