  For example, the alignment plate 34 is moved to the second position b when the width dimension of the bankbook T is detected, and when the width dimension of the statement sheet Sb wider than the bankbook T is detected, the alignment plate 34 is moved to the second position b. When the width dimension of the statement sheet Sb narrower than the passbook T is detected, it is moved to the third position a.

  Further, when the bankbook T or the statement sheet Sb inserted from the fascia section 2 reaches the alignment area 31, the control unit 24 raises the alignment roller 33 to contact the lower surface side of the bankbook T or the statement sheet Sb. In addition, the passbook T or the statement sheet Sb is moved toward the alignment plate 34 by being rotated.

  Next, the printing operation of the printing apparatus configured as described above will be described.

  First, a case where printing is performed using the thermal paper 4 will be described.

  The leading end side of the thermal paper 4 is sandwiched between the first and second platen rollers 20 and 21 and the first and second thermal heads 17 and 18 as shown in FIG. When the ment issue button 27 is turned on, the first drive motor 25 is driven to rotate the platen rollers 20 and 21. By this rotation, the thermal paper 4 is conveyed, and information is printed on the front and back surfaces of the thermal paper 4 by the heat generated by the first and second thermal heads 17 and 18. After this printing, the thermal paper 4 passes through the cutting section 8 and is nipped and conveyed by the thermal-side feed roller pair 14, and when the leading edge is detected by the thermal paper detection sensor 28 as shown in FIG. Rotates and the thermal paper 4 is cut to a predetermined size to form the statement paper Sa. The statement sheet Sa is conveyed along the conveyance path 6b by the reverse rotation of the feed roller pair 15, the conveyance roller pair 11, and the loading / unloading roller pair 12 as shown in FIG.

  Next, a case where printing is performed on the passbook T inserted from the fascia section 2 or a plurality of types of statement sheets Sb having different width dimensions will be described.

  When the bankbook T or the statement sheet Sb is inserted from the fascia section 2, it is detected by the insertion detection sensor 29 as shown in FIG. When this is detected, the second drive motor 26 operates to rotate the entrance / exit roller pair 12, the transport rollers 11a to 11e, and the feed roller pair 15 in the first direction. By this rotation, the bankbook T or the statement sheet Sb is conveyed along the conveyance path 6 b, and the width dimension is detected by the width detection sensor 30. Based on this detection, the alignment plate motor 46 is driven, and the alignment plate 34 is moved to the first position a as shown in FIG. 8 or the second position b as shown in FIG. 9 or as shown in FIG. To the third position c.

  That is, FIG. 8 shows the position of the alignment plate 34 when the statement sheet Sb wider than the bankbook T is conveyed to the alignment area 31, and FIG. 9 illustrates the alignment when the bankbook T is conveyed to the alignment area 31. FIG. 10 shows the position of the alignment plate 34 when the statement sheet Sb narrower than the passbook T is conveyed to the alignment area 31.

  When the bankbook T or the statement sheet Sb reaches the alignment area 31, the alignment roller 33 is raised and contacts the lower surface side of the bankbook T or the statement sheet Sb and rotates. As a result, the bankbook T or the statement sheet Sb is moved toward the alignment plate 34. In the case of the bankbook T, the alignment is performed by contacting the alignment plate 34 moved to the second position b as shown in FIG. In the case of the statement sheet Sb wider than the bankbook T, as shown in FIG. 8, the statement sheet Sb is brought into contact with and aligned with the alignment plate 34 moved to the first position a, and is narrower than the bankbook T. In the case of Sb, as shown in FIG. 10, the alignment is performed by contacting the alignment plate 34 moved to the third position c.

  The passbook T or statement paper Sb positioned in this way is conveyed to a printing position as shown in FIG. 11 and printed by the dot head 9a. When printing is completed, the second drive motor 26 causes the pair of entrance rollers 12, the feed roller pair 15, and the transport rollers 11 a to 11 e to rotate in the second direction. By this reverse rotation, the bankbook T or the statement sheet Sb is fed back and sent out from the fascia section 2.

  As described above, according to this embodiment, since the position of the alignment plate 34 is varied along the width direction of the print medium based on the width dimension of the print medium such as the passbook T and the statement paper Sb, a single Even the alignment plate 34 has an advantage that printing media having various width dimensions can be positioned, the configuration can be simplified, and the cost can be reduced.
