(See FIG. 6). Also,
To prevent this, if the urging force of the pressing spring 106 is reduced in order to reduce the force with which the postcard a is pressed against the guide wall 102, the upper roller 103 bounces greatly against the postcard a riding on the lower roller 104. Therefore, there is a problem that the contact time is short, and the transmission of the width-shifting force to the postcard a is small, and the contact cannot be sufficiently performed. FIG. 8 shows the upper roller 1 due to the repulsive force received from the postcard a when the postcard a passes between the upper roller 103 and the lower roller 104 in this conventional example.
03 shows a bouncing phenomenon in which after jumping up from postcard a against the urging force of pressing spring 106, it comes into contact with postcard a again with the urging force. In the case of a small size such as postcard a, if the cycle of the bouncing is long, the upper roller 103 may be used while the postcard a passes between the rollers 103 and 104.
Can contact the postcard a only several times, in the case shown in the figure, only three times, and the transmission of the width shifting force to the postcard a is small.

The upper roller 21 can be displaced in the vertical direction with respect to the lower roller 22 by being freely supported and by allowing the support shaft 21a of the upper roller 21 to swing vertically about the fulcrum 24. It is. A pressing spring 2 pressed by a pressing member 25 is provided above the support shaft 21a.

書ａへ幅寄せ力の伝達が足りないことがわかる。The pressing spring 26 always applies an urging force to the support shaft 21a. However, when the postcard a passes between the upper roller 21 and the lower roller 22, the upper roller 21 receives a repulsive force from the postcard a. After jumping up, a bouncing phenomenon occurs in which the card comes into contact with the postcard a again by the urging force. The damper 27 does not always exert any action, but generates a force for absorbing the swinging power when the support shaft 21a swings upward. Therefore, after the upper roller 21 jumps up as described above, the time until the contact with the postcard a again, that is, the bounce period is shortened. As shown in FIG. 22, for example, after seven times contact with postcard a,
The force to shift the width is sufficiently transmitted. By the way, in the case of the conventional example, since the thing corresponding to the damper 27 of the present embodiment is not provided, as shown in FIG.
Can contact the postcard a only, for example, three times, and it can be understood that the transmission of the width shifting force to the postcard a is insufficient.

a, 22a rotatably supported on a support shaft 28a parallel to the
In the transport path 4 near the width-adjusting portion 23 in the forward direction of the single-sheet paper a, the upper outer peripheral surface thereof is higher than the transfer surface of the postcard a in the width-adjustment portion 23.
That is, the transport belts 4a and 4b are arranged to be lifted upward.

ある。The roller 28 causes the postcard a, which is being width-adjusted by the width-adjusting portion 23, to ride over the postcard a, thereby transforming the postcard a three-dimensionally into a curved state when viewed from the lateral direction. Even if the postcard a is pressed against the wall 20, the postcard a is less likely to be warped and wrinkles are less likely to be formed.

あるいは雑スタッカ装置１２に向かう。Next, the operation of the width shifting device 1 will be described. When the postcard a is supplied from the paper supply section 3 to the transport path 4, the postal code is read by the code reader 5, and the control section 17 determines whether the postal code is legitimate. If the postal code is legitimate, the sorting stacker device 6a, 6b, and is controlled to be sent to the reject stacker device 13 or the miscellaneous stacker device 12 if it is not regular. The postcard a is conveyed while being sandwiched between the upper conveyance belt 4a and the lower conveyance belt 4b of the conveyance path 4. When the postcard a reaches the width adjusting portion 23 of the width adjusting device 1, the postcard a is sandwiched between the upper roller 21 and the lower roller 22 while receiving the pressing force of the pressing spring 26.
Begin skew to the side. Subsequently, the skewed postcard a rides on the roller 28, hits the guide wall 20 while being curved and deformed in the traveling direction, and is conveyed along the corrected conveyance path while being pressed. As described above, since the postcard a abuts on the guide wall 20 in a state of being curved in a substantially U-shape, the postcard a does not warp or wrinkle. Then, according to the control of the control unit 17, the reject stacker device 13, the sorting stacker devices 6a, 6b
Or, it goes to the miscellaneous stacker device 12.

The deposited postcard a is obtained. The deposited postcard a is transferred to the display tag attaching device 7a, and after the discount tag is placed, the band 8 is hung in the width direction by the first banding device 9a. Further, when the postcard a has been accumulated in the sorting stacker device 6a by the predetermined number, the postcard a conveyed through the conveying path 4 is prevented from being carried into the carrying path of the other sorting stacker device 6a, and is carried into the sorting stacker device 6b. And
The same operation as described above is sequentially performed during the transfer to the display tag attaching device 7b and the first strapping device 9b.

い。The present invention is not limited to the above-described embodiment. For example, the upper roller 21 may be replaced with the lower roller 2.
Instead of urging it against the lower roller 2
2 may be configured to urge the upper roller 21 against the upper roller 21. If the roller 28 extends across the transport path 4, the upper roller 21 or the lower roller 22 may be used.
It is not necessary to provide the axes of each other in parallel. Further, instead of the sponge, the damper 27 may be replaced by another spring or the like that generates a force for absorbing the displacement force only when the upper roller 21 is displaced upward.

いう効果を奏する。As described above, according to the first aspect of the present invention, there is provided a width-adjusting portion for pressing one roller against the other roller, and an outer peripheral surface crossing the conveying path. Since the upper side is provided with a roller that is higher than the transfer surface of the single-sheet paper in the width-adjusting unit, the single-sheet paper during the width-adjustment is three-dimensionally deformed into a curved state when viewed from the side and pressed against the guide wall. It has the effect of being less likely to warp and wrinkles less likely to occur.

を単片用紙に充分に伝達できるという効果を奏する。According to a second aspect of the present invention, there is provided a width adjusting portion for pressing one roller against the other roller, and the width adjusting portion is arranged so as to cross a conveying path and to have an upper outer peripheral surface thereof. Since the rollers that are higher than the transfer surface of the single-sheet paper in the section are provided, the single-sheet paper being width-adjusted is three-dimensionally deformed into a curved state when viewed from the side, and is not easily warped even when pressed against the guide wall. In addition, wrinkles are less likely to be formed, and a damper is provided on the one roller. Only when this one roller is displaced in the direction opposite to the biasing direction, the damper absorbs this displacing force. This has the effect of shortening the bounce period of one roller on the single-sheet paper, and sufficiently transmitting the width shifting force to the single-sheet paper.
