てして搬送される。The apparatus body 2 is connected online to a computer center (not shown). Further, since the passbook has a narrower insertion width than the slip and the width of the insertion slot 1 is set to the width of the maximum width slip or the like, the passbook or the narrow slip or the like is placed on one side wall 60a of the transport path 6a. As the reference surface, it is conveyed by abutting upon insertion.

If you do not do this, the medium 5a will shift when you release your hand after hitting it, or it will bounce off the side wall 60a due to the resilience of the medium 5a, and will be separated from the side wall 60a or inclined, so it will take time to operate. However, in order to cover this, the width of the medium 5a is reduced.

す幅寄せ位置へ送られる。The method of sucking the medium 5a into the passbook printer will be described in detail. As shown in FIG. 11, first, the medium 5a is inserted from the insertion opening 1 in the direction of arrow A and abutted against the stopper 7, and the sensor S detects the medium 5a. Is detected, and a plunger magnet (hereinafter referred to as PM) (not shown) is excited,
The stopper 7 is retracted, the pressing rollers R3, R4 are closed, the feed rollers R1, R2 are rotated by the driving of a pulse motor (hereinafter referred to as a motor) M1, and the medium 5a is fed to the width-shift position shown by the broken line in the figure.

る。As shown in FIG. 12 (b), if only the detection by the sensor S1 (or only the sensors S3, S1 or only the sensors S2, S1) is performed, the medium 5a needs to be width-aligned and the PM The excitation is released, the feed rollers R1 and R3 are opened, the motor M2 rotates, and the pinion G is installed on the motor shaft.
The rack 91 provided on the push plate 9 is moved by the rotation of the push plate 9, and the push plate 9 is moved in the direction of the arrow C, so that the pressing surface 90 of the push plate 9 moves the medium 5a to the left side as shown in FIG. 12 (c). Sidewall 60
When the sensor S2, S3 hits a, and the sensors S2 and S3 detect the widthwise movement, the reverse rotation of the motor M2 causes the push plate 9 to retract and return to the home position, and the medium 5a is sent to the printer unit 8.

13 (Conventional example (2)) As shown in (a) to (c), two driving rollers R5 and R6 having a rhombic cross section are provided in the transport direction and the lateral direction.
And pressing rollers R7 and R facing the driving rollers R5 and R6, respectively.
8, the pressing roller R7 is normally retracted to the lower side of the conveyance path 6b and protrudes into the conveyance path 6b when the width is adjusted.

【００１４】従って、駆動ローラR5,R6 が矢印方向に回

る。As described above, in the conventional method, in the conventional example (1), when the medium is a thin medium such as a slip, when the medium is width-shifted by the push plate, the edge of the medium is narrowed. The part may collide with the side wall and cause buckling or damage, which may result in no reliable effect. Moreover, since the conveyance of the medium is temporarily stopped and the width adjustment is performed, the bookkeeping processing time is long.

いために、複数枚重ね媒体（複写伝票）の層間ズレを引
き起こし易い。In the conventional example (2), the width of the medium can be shifted only in one direction, and when the medium is rotated in the reverse direction, the medium is separated from the side wall. In addition, since the roller and the medium are not reliably gripped, it is easy to cause the interlayer deviation of the multiple-layered medium (copy slip).

い。という問題点がある。Further, as a problem common to the conventional example (1) and the conventional example (2), a mechanism for exclusive use of the width adjustment is required, resulting in high cost. Further, it is difficult to uniformly perform width-shifting processing on media such as passbooks, slips, and certificates having different properties. That is, when a large width-adjusting force is applied in order to move a medium such as a passbook having a large conveyance resistance to a large width, it causes an excessive abutment of the medium such as a slip with a weak stiffness, and folds or wrinkles. However, if the width adjusting force is weakened by adapting to a medium having a low stiffness, the medium having a large conveyance resistance cannot be surely width adjusted. There is a problem.

る。That is, when the roller 11 and the rotating body 12 sandwich and convey the medium 5 by the rotation of the rotating shaft 10, the outer periphery of the roller 11 is pushed by the outer periphery of the rotating body 12 so that the upper end of the V-shape is closed. The amount of deflection and displacement at a constant rotation angle, that is, the amount of movement of the medium 5 is obtained by the operation of shifting from the position where the medium 5 contacts the outer periphery of the roller 11 to the maximum displacement point of the roller 11.

While being conveyed, the width is adjusted in the direction of the side wall 60. In addition, since the amount of bending of the roller 11 varies depending on the thickness of the medium 5, a conveyance resistance and a width-shifting force corresponding to the thickness can be obtained, and reliable width-shifting can be performed.
