DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a width shifting mechanism for transporting a medium such as a bookkeeping machine used in a financial institution, and more particularly to at least a pair of impellers having different transfer forces depending on the type of the medium. The present invention relates to a medium width shifting mechanism capable of width shifting.

2. Description of the Related Art In recent years, transaction data is recorded by an automatic teller machine (hereinafter referred to as ATM) used in financial institutions and a passbook printer incorporated in a bookkeeping machine. In addition, transaction data is entered in slips of different sizes depending on the type of transaction.

When such a print medium is inserted along the guide surface when inserted into the medium insertion slot of the bookkeeping machine, it is often skewed, and the skew is corrected by the width shifting mechanism. When the medium has a concave warp upward, the end of the warped medium comes into contact with the feed roller, so that the width of the medium is not smoothly adjusted due to friction, and the medium has a weak waist such as a slip. In such a case, the end of the warped medium comes into contact with the impeller and an unnecessary increase in the transfer force is strongly pressed against the abutting surface to cause a jam, so that the warpage is corrected and the width adjustment is normally performed. A method is desired.

[0004]

2. Description of the Related Art A conventional method will be described with reference to FIGS.
The same reference numerals indicate the same objects throughout the drawings.

FIG. 6 shows a bookkeeping machine to which the present invention is applied. As shown in the figure, the bookkeeping machine is a passbook 5a or a slip 50.
A main body 2 having an insertion slot 1 into which a key is inserted, a keyboard (hereinafter referred to as KB) 3 for inputting the customer's account number, transaction details, etc., and a display (hereinafter, referred to as CRT) for displaying the contents of operation processing and the like. ) 4.

The apparatus main body 2 is connected online to a computer center (not shown). Usually, the passbook 5a has a smaller insertion width than the voucher 50, and the width of the insertion slot 1 is set to the width of the maximum width voucher.
50 is conveyed with the side wall 60a of the conveying path 6a as a reference plane.

[0007] Therefore, when the teller inserts the passbook 5a or the slip 50 (to be described below with the passbook) from the insertion slot 1 and inputs the transaction data from the KB3, it is displayed on the CRT4. Then, communication with the computer center is performed, and the transaction data is printed on the passbook 5a and discharged.

Here, the method of inhaling the passbook 5a into the device will be described in detail. First, as shown in FIG.
When the passbook 5a is inserted in the direction of arrow A, the passbook 5a is detected by the sensor S, and the lever mechanism (not shown) is actuated by the excitation of the plunger magnet (hereinafter referred to as PM) 8a to close the pressing rollers R3 and R4. In this state, the feed rollers R1 and R2 rotate by the drive of the motor M1 and the passbook 5a
Is sent to the width-shift position indicated by the broken line in the figure.

At this time, as shown in FIG. 8 (a), if the passbook 5a is guided by the left side wall 60a of the transport path 6a and there is no skew, both sensors S2 and S3 detect the passbook 5a. The passbook 5a is detected, and the leading end of the passbook 5a is detected by the sensor S1, so that the passbook 5a is sent to the printer unit 7 as it is without the need for a width adjustment operation.

As shown in FIG. 8B, if only the detection of the sensor S1 (or only the sensors S3 and S1 or only the sensors S2 and S1) is performed, the passbook 5a needs to be corrected for skew. The width adjustment is performed by the method described below.

Regarding the width shifting mechanism, the present applicant has
Japanese Patent Application No. 62-044755, entitled "Paper Width Shifting Mechanism" and Japanese Patent Application No. 03-168579, "Medium Width Shifting Mechanism", are outlined below with reference to FIG.

As shown in plan and front views of FIGS. 9 (a) and 9 (b), a plurality of impellers 9a to 9c made of a flexible material having a high coefficient of friction, for example, urethane rubber, are used. , Passbook 5a
Provided to rotate in a direction perpendicular to the transport direction of the
The shafts 10a and 10b of the impeller 9a and the impellers 9b and 9c are rotatably supported by the holding member 11.

[0013] The length of the impeller 90a of the impeller 9a is the impeller 9b, 9c.
Of the blades 90b, 90c (ie, the impeller 9a
Is larger than the diameter of the impellers 9b and 9c).
The holding member 11 has a U-shaped cross section with a downward cross section, and a part of a drive mechanism described later is provided therein. Is rotatably supported.

One end of a lever 13 is fixed to the rotating shaft 12, and the other end is connected to a PM 14a and a recovery spring 15.
The holding member 11 swings in the directions of arrows C and D due to the excitation / de-excitation of “a”.

The holding member 11 is normally at a position shown by a two-dot chain line in the figure, that is, at a position rotated in the direction of arrow D.
In 9a to 9c, the tips of the blades are retracted from the transport path 6a. When the holding member 11 is turned in the direction of arrow C, the holding member 11 is stopped at a horizontal position by a stopper (not shown).
9c enter the transport path 6a from the holes 16a to 16c provided in the upper plate 61 of the transport path 6a, and the tip of the blade 90a is slightly bent by contacting the upper surface of the lower plate 62 of the transport path 6a. 90b, 90c is lower plate
The length is set so as to be slightly away from the upper surface of 62.

As shown in FIG. 10 (a), a pulley P1 sliding on the rotating shaft 12, a pulley P2, P3 on the shaft 10b, a pulley P4 on the shaft 10a, and a pulley P1 via the belt B1 are provided. The pulley P1 and the pulley P2, and the pulley P3 and the pulley P4 are connected by belts B2 and B3, respectively. Therefore, the rotation of the motor M2 causes the impellers 9a to 9c to rotate.

The feed rollers R1 and R2 are not shown for simplification of the drawing. With such a configuration, when correcting the skew of the passbook 5a, the excitation of the PM 8a is released to open the rollers R3 and R4, and at the same time, the impellers 9a to 9c are driven by the motor M2 to move the arrows E to E. While rotating in the direction, when the PM 14a is excited and the impellers 9a to 9c enter the transport path 6a and come into contact with the passbook 5a, the passbook 5a moves due to the bending and friction of the rotating impellers 9a to 9c, Side wall of transport path 6a
It is shifted to 60a.

When the sensors S2 and S3 detect the width shift, the motor M2 is stopped, the excitation of the PM 14a is released, the impellers 9a to 9c are retracted to the normal position, and then the PM 8a is excited to excite the pressing roller. R3 and R4 are closed, and the passbook 5a is sent to the printer unit 7 by driving the feed rollers R1 and R2. The passbook 5a on which the transaction data is printed by the printer unit 7 is conveyed in the direction of arrow B and sent out from the insertion slot 1.

In the skew correction in the case of a single form such as the form 50, as shown in FIG. 10B, since the form 50 is thinner than the passbook 5a, the impellers 9b and 9c It is not brought into contact with 50, but is moved closer to the side wall 60a only by the impeller 9a.

That is, in the case of a thin and slim medium such as the slip 50, if the transfer force of the width shift is large, the end of the slip 50 is pressed against the side wall 60a, and a jam occurs due to buckling, which is prevented. For this reason, the width is adjusted only by the transfer force of the impeller 9a.

[0021]

According to the above-mentioned conventional method, when the bankbook 5a is concavely deformed upward, that is, when the passbook 5a is warped, the impeller 9b and the impeller 9c are arranged at intervals. Although the warp near that position is corrected, it is not corrected at a distant position, for example, at the position of the impeller 9a, and as shown in FIG. 11, the end of the passbook 5a comes into contact with the feed rollers R1 and R2 to cause friction. The load becomes large, and smooth rotation of the impellers 9a to 9c due to rotation is not possible.

If the cut-sheet medium such as the slip 50 is warped, the slip 50 comes into contact with the impellers 9b and 9c which should not be in contact with each other. Car 9
Unnecessary transfer forces b and 9c are applied, and are strongly pushed by the side wall 60a, so that buckling may cause a jam. There is a problem.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a width shifting mechanism which can smoothly adjust the width of a medium having a warp for correcting skew.

[0024]

FIG. 1 is a diagram showing the principle of the present invention, in which (a) is a plan view and (b) is a front view. In the figure, 5 is a medium, 6 is a transport path, 10 is an axis, 60 is a side wall, 19 is a medium detecting means for detecting that the medium 5 transported on the transport path 6 has reached a predetermined position on the transport path 6, 21 Is a skew detecting means for detecting the presence or absence of skew of the medium 5 when the medium 5 is detected by the medium detecting means 19, and 20 is located at a predetermined position before the medium detecting means 19 in the direction of conveyance of the medium 5. At least one pair of feed rollers, which are provided at right angles to each other, protrude into the transport path 6 from above and below, and pinch and transport the medium 5, are skew detecting means.
Evacuation means for retreating at least the lower feed roller 20 from the conveyance path 6 when the skew is detected by 21, and the conveyance path 6, which is about half the length of the medium 5 from the medium detection means 19, is provided.
Upper vertically movably provided on the flexible and, small crows and <br/> also one of the impeller 17 is freely least fixed or rotating to one side of the impeller 9 to the impeller 9 coaxially A guide plate 14 having a predetermined diameter is provided. When the skew detecting means 21 detects the presence of skew, the impeller 9 and the guide plate 17 enter the transport path 6 so that at least the impeller 9 Lifting means 22 for lowering the impeller 9 to a predetermined position in contact with 5, and drive control means 22 for rotating the impeller 9 in a predetermined direction when the impeller 9 has lowered to the predetermined position.

Accordingly, the rotation of the impeller 9 conveys the medium 5 toward one of the side walls 60 of the conveyance path 6, and the drive control means 22 drives the impeller 9 until the skew detecting means 21 detects no skew. Is configured to continue.

[0026]

The medium 5 transported along the transport path 6 is supplied to the medium detecting means 19.
Is detected, the skew detecting means 21 detects the presence or absence of skew of the medium 5.

Subsequently, when the impeller 9 and the guide plate 17 are lowered by the elevating means 14 and enter the transport path 6 and at least the impeller 9 comes into contact with the medium 5, the impeller 9 is rotated by the drive control means 22. The medium 5 is transported in the direction of one of the side walls 60 by the flexibility and frictional force to narrow the width.

If the medium 5 has a concave warp upward, when the impeller 9 and the guide plate 17 descend, the guide plate 17 comes into contact with the warped end of the medium 5 and warps the medium 5. Is corrected, and the rotation of the impeller 9 moves the medium 5 toward the side wall 60.

When the skew detecting means 21 detects that the medium 5 is not skewed, the rotation of the impeller 9 by the drive control means 22 is stopped. In this manner, when the medium 5 is warped, the end of the medium 5 can be pressed down by the guide plate 17 to correct the warp.
This can prevent an increase in load at the time of width adjustment due to friction due to contact, and can smoothly perform width adjustment for skew correction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention (corresponding to claims 1 and 2) will be described with reference to FIGS. 2 is a block diagram showing the embodiment, FIG. 3 is a control block diagram of the embodiment, and FIG. 4 is an explanatory diagram of the embodiment. The same reference numerals indicate the same objects throughout the drawings.

The sensors S1, S2 and S3 and the drive control section 22a of FIGS. 2 and 3 correspond to the medium detection means 19, the skew detection means 21 and the drive control means 22 of FIG. 1, respectively. 4
The passbook 5a and the slip 50 correspond to the medium 5 in FIG. 1, and the feed rollers R1, R2 and the press rollers R3, R4 in FIGS. 2 and 3 correspond to the feed roller 20 in FIG.

The PM8a and lever mechanism shown in FIGS.
80 corresponds to the retracting means 8 in FIG. 1 and the holding member in FIG.
11, the rotating shaft 12, the lever 13, the PM 14a and the recovery spring 15
This corresponds to the elevating means 14 in FIG.

As shown in FIGS. 2A and 2B, the impeller 9a
Disc-shaped guide plates 17a and 17b each having a diameter slightly smaller than that of the impeller 9a are coaxially fixed to both ends of the shaft 10a, and the shafts of the impellers 9b and 9c.
At both ends of 10b, do not touch the impellers 9b, 9c.
Disc-shaped guide plates 17c and 17d having substantially the same diameter as 9b and 9c are
Holes 18a and 18b (corresponding to the hole of claim 2) larger than b are fitted.

A spacer having a diameter larger than the holes 18a, 18b is fitted to the end of the shaft 10b outside the guide plates 17c, 17d so that the guide plates 17c, 17d do not fall off the shaft 10b.
However, in FIG. 2B, the inside is shown without spacers.

The dimensional difference between the diameter of the shaft 10b and the diameter of the holes 18a, 18b is set at least to the maximum thickness of the passbook 5a, so that the guide plates 17c, 17d are only the maximum thickness of the passbook 5a relative to the shaft 10b. Can move up and down.

The guide plates 17a and 17b do not contact each other when the holding member 11 is in the horizontal position and the passbook 5a or the slip 50 on the transport path 6a does not have any upward concave warp. When it comes to contact with the passbook 5a or the slip 50, the warp is corrected to be small.

The guide plates 17c, 17d are set to have substantially the same diameter as the impellers 9b, 9c. When the holding member 11 is in a horizontal position, the guide plates 17c, 17d contact the passbook 5a or the slip 50 on the transport path 6a by their own weight.
The vertical position is determined according to the thickness.

Therefore, when the impeller 9a rotates, the guide plates 17a,
17b also rotates, but even if impellers 9b and 9c rotate, the guide plate
17c and 17d do not rotate. However, when the passbook 5a or the slip 50 is moved by the rotation of the impellers 9a to 9c,
The guide plates 17c and 17d also rotate according to the movement.

In FIG. 3, the drive control section 22a
A PU and a control program are provided, and the CPU controls each unit according to the control program, and controls the transport and width adjustment of the passbook 5a or the slip 50 based on the medium detection signal and the skew detection signal of the sensors S, S1 to S3. .

Reference numeral 23 denotes a sensor amplifier, 24 denotes a magnet driver, and 25 denotes a motor driver. With such a configuration, similarly to the description of the conventional example, the passbook 5a inserted into the insertion slot 1 is detected by the sensor S, and the PM 8a is excited by the control of the drive control unit 22a to press the pressing rollers R3, R4. Is closed, the feed rollers R1 and R2 rotate by the drive of the motor M1, and the passbook 5a is conveyed.

When there is no skew when guided by the left side wall 60a of the transport path 6a to the width approaching position, both sensors S2 and S3 detect the passbook 5a, and furthermore, the passbook 5a
Is detected by the sensor S1, so that the passbook 5a is sent to the printer unit 7 without any need for a width adjustment operation.

If only the detection of the sensor S1 (or the sensor S1
(3, S1 only or sensors S2, S1 only), the excitation of PM8a is released and the holding rollers R3, R4 retreat from the conveyance path 6a, and then the motor M2 is driven, and the PM14a is excited. The holding member 11 rotates in the direction of arrow C and is positioned horizontally.

Then, all the tips of the rotating impellers 9a to 9c contact the passbook 5a on the upper surface of the lower plate 62 of the transport path 6a, and the passbook 5a
If there is no upward warp, the guide plates 17a and 17b do not contact the passbook 5a, but the guide plates 17c and 17d contact the passbook 5a by its own weight, and rotate the passbook 5a to the side wall 60a by rotation of the impellers 9a to 9c. The sheet is transported in the direction and the width is adjusted.

At this time, if the passbook 5a has a concave warp upward, as shown in the main part front view of FIG.
17b rotates and makes contact with the warped up portion of the passbook 5a and pushes it down.
Correct the warpage so as not to contact R1 and R2. The guide plates 17a and 17b which rotate in contact with the passbook 5a in this state slightly contribute to an increase in the transfer force for moving the passbook 5a to the width.

Further, the guide plates 17c and 17d cannot correct the warp by their own weights, and are located above the upper surface of the lower plate 62 of the transport path 6a in a state of being in contact with the warped passbook 5a. Therefore, it is possible to prevent an increase in load due to friction caused by the contact between the passbook 5a and the feed rollers R1 and R2.

FIG. 4 (b)
As shown in the side view, when the holding member 11 is positioned horizontally by the excitation of the PM 14a, the tip of the impeller 9a is in contact with the slip 50, but if the slip 50 has no concave warpage upward, the guide The tips of the plates 17a, 17b and the impellers 9b, 9c are located slightly above the chit 50 surface, and the guide plates 17c, 17d contact the chit 50 surface by their own weight, and the chit 50 is moved only by the transfer force due to the rotation of the impeller 9a. The width is shifted toward the side wall 60a.

At this time, if the voucher 50 has a concave warp upward, the guide plates 17a to 17d come into contact with the warped up portions of the voucher 50 and press down, and the guide plates 17a and 17b The guide plates 17c, 17d correct the warpage so that the ends do not contact the feed rollers R1, R2, and the guide plates 17c, 17d prevent the warped slip 50 from contacting the impellers 9b, 9c.

Therefore, it is possible to prevent an increase in load due to friction generated by the contact between the slip 50 and the feed rollers R1 and R2, and to prevent the slip caused by the slip of the slip 50 from contacting the impellers 9b and 9c. Since an increase in the force can be prevented and the width is shifted only by the impeller 9a, the occurrence of a jam due to the buckling of the slip 50 can be prevented.

When the skew of the passbook 5a or the slip 50 is corrected, the drive control unit 22a stops driving the motor M2 and stops the rotation of the impellers 9a and 9c by detecting the sensors S2 and S3. The excitation is released and the holding member 11 is rotated in the direction of arrow D to retract the impellers 9a and 9c from the transport path 6a.

Then, the PM 8a is excited to hold down the press rollers R3, R4.
To close the feed roller R by driving the motor M1.
The passbook 5a or the slip 50 is conveyed to the printer unit 7 by the rotation of R1 and R2.

FIG. 5 shows a different embodiment (corresponding to claims 2 and 3). FIG. 5 differs from the embodiment described in FIG. 2 in that disc-shaped guide plates 17a and 17b are used instead of disc-shaped guide plates 17a and 17b.
It is an impeller-shaped guide.

That is, as shown in the side view of FIG.
Guide wheels 17e, 17f formed of the same material and the same diameter and shape as the impellers 9b, 9c at both ends of the shaft 10a of the 9a (that is, the impellers 9b, 9c
And the same) are fixed.

With such a configuration, when the bankbook 5a has a concave warp upward, the holding member 11 is used to correct skew.
Is positioned horizontally, the tips of the rotating impellers 9a to 9c contact the bankbook 5a, and the guide wheels 17e, 17f rotate and contact with the warped and raised portions of the bankbook 5a to push down and warp the bankbook. The warpage is corrected so that the end of 5a does not contact the feed rollers R1 and R2.

Then, the passbook 5a is transferred in the direction of the side wall 60a by the transfer force due to the rotation of the impellers 9a to 9c, and the width is adjusted. Therefore, it is possible to prevent an increase in load due to friction caused by the contact between the passbook 5a and the feed rollers R1 and R2.

When the slip 50 has a concave warp upward,
When the holding member 11 is positioned horizontally for skew correction, the tip of the rotating impeller 9a contacts the slip 50, and the guide wheels 17e, 17f contact the warped and raised portion of the slip 50 while rotating. Press down to correct the warp,
17c and 17d correct the warpage so that the warped slip 50 does not contact the impellers 9b and 9c, and the width is adjusted by the transfer force due to the rotation of the impeller 9a.

In this case, the guide wheels 17e and 17f and the impeller
9b, since 9c is the same member can be used in common, component type
Types can be reduced. In this way, passbook 5a
Alternatively, even if the media having different thicknesses such as the slip 50 have concave warpages upward, the warpage can be corrected by the guide plates 17a to 17d or the guide wheels 17e, 17f and the guide plates 17c, 17d. Therefore, it is possible to smoothly perform width adjustment for correcting skew.

In the above-described embodiment, the case where the guide plates 17a, 17b are fixed to both ends of the shaft 10a of the impeller 9a has been described. However, the transfer force of the width shifting due to the rotation of the guide plates 17a, 17b together with the impeller 9a. If it is not necessary to increase the number of guide plates 17a,
17b may be rotatably mounted, and the same effect can be obtained.

[0058]

As described above, according to the present invention, according to the first aspect, a guide plate having a predetermined diameter is provided coaxially with the impeller on at least one side of the width adjusting impeller for correcting skew of the medium. By fixing or rotating freely, when the medium has a concave warp upward, the warp is corrected and the end of the medium is prevented from contacting the feed roller to increase the friction, and the width is smoothly adjusted. It can be performed.

According to the second aspect, the guide plate has a hole having a diameter larger by a predetermined dimension than the shaft of the impeller, and the hole is fitted into the shaft, whereby the guide plate can be moved up and down by a predetermined size. The guide plate can correct the warp by its own weight when a thin and weak cut-sheet medium such as a slip has a concave warp upward.

Accordingly, when a plurality of impellers having different diameters are used and the guide plate is fitted on the shaft of the impeller having a small diameter as in the above embodiment and different embodiments, the medium having a thin and weak waist is warped. By correcting the warpage so that the end does not contact the impeller, it is possible to prevent an unnecessary increase in the media transfer force, and the media is strongly pushed by the side wall and a buckling causes a jam. Can be prevented.

According to the third aspect of the present invention, the guide plate fixed to the shaft of the impeller is formed in the shape of an impeller using the same material as the impeller, so that the warpage of the medium can be corrected and the number of parts can be reduced. And cost can be improved. This has the effect.
