Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a medium conveyance abutting guide used for a passbook slip printer and guiding the end portion of the medium during conveyance.

[0002]

[Prior art]

 Conventionally, as a medium carrying abutting guide used for a passbook slip printer and guiding the end of the medium at the time of transportation, a lower guide that abuts against its side wall is used. Hereinafter, such a conventional medium conveying butting guide will be described with reference to the drawings.

FIG. 4 is a schematic view of a conventional passbook slip printer, FIG. 5 is a detailed view of part A of FIG. 4, FIG. 6 is a perspective view showing the shape of a lower guide, and FIG. 7 is a perspective view showing a conventional butting guide. 8 is a sectional view taken along the line BB 'of FIG. 5, and FIG. 9 is a sectional view taken along the line CC' of FIG.

In FIG. 4, a passbook voucher printer 1 for carrying a medium such as a passbook or a voucher has upper and lower insertion stages 2 and 3. The two conveying paths 4 and 5 are joined together in front of the printing unit 8 including the print head 6 and the platen 7. The medium 9 inserted from the insertion slot 2 passes through the conveyance path 4 and is printed by the printing unit 8 and then discharged from the insertion slot 2 through the conveyance path 4 again. When the medium 9 is inserted through the insertion port 3, the medium 9 passes through the conveyance path 5, is printed by the printing unit 8, and then is ejected from the insertion port 3 through the conveyance path 5 again.

Next, the detailed structure of the portion A in FIG. 4 will be described. In FIG. 5, the transport path 4 is composed of three guides, a butting guide 10, a lower guide 11, and an upper guide 12. As shown in FIG. 7, the abutting guide 10 has an L-shaped cross section having a step between the side wall 13 which is a medium abutting surface and the upper guide abutting surface 14. The abutting guide 10 serves as a reference end for the printing unit 8 when the medium 9 is conveyed and guides the end of the medium 9 so that the medium 9 is not bent. The lower guide 11 has an abutting surface 15 as shown in FIG. The abutting surface 15 has a shape along the back surface 16 of the abutting guide 10 as shown in FIG. 7, and abuts against the side wall 13 of the abutting guide 10 to be fixed. The upper guide 12 has a shape along the upper guide abutting surface 14, and as shown in FIGS. 8 and 9, is fixed in contact with the upper guide abutting surface 14.

By the way, as shown in FIG. 8, a groove 17 is formed at an abutting portion between the lower guide 11 and the butting guide 10 due to variations in bending accuracy between the lower guide 11 and the butting guide 10, processing, assembly and the like. Further, as shown in FIG. 9, a gap 19 is formed between the side wall 13 of the butting guide 10 and the claw portion 18 of the lower guide 11. The end portion 20 of the medium 9 may enter the groove 17 and the gap 19 during transportation or ejection of the medium 9.

[0007]

[Problems to be solved by the device]

 In the conventional media transport abutting guide, if the edge of the medium abuts against the side wall of the media transport abutting guide during the transport and discharge of the medium, the edge of the medium will move between the media transport abutting guide and the lower guide. Since it may get caught in a groove or a gap and get caught, there is a problem that the medium is not properly conveyed such as bending in the conveying direction, tearing of the medium, and jamming.

According to the present invention, when the end of the medium hits the side wall of the medium feeding abutting guide during the feeding and discharging of the medium, the medium feeding does not occur such as bending of the medium, tearing of the medium, and jamming. It is intended to provide an end-to-end guide.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, in the medium conveying butting guide of the present invention, a step is formed between the contact surface between the lower guide and the medium conveying butting guide and the medium butting surface of the medium conveying butting guide. Was set up.

[0010]

[Action]

 When the medium is conveyed along the medium abutting surface of the medium conveying abutting guide configured as described above, the medium abutting surface between the lower guide and the medium conveying abutting guide and the medium abutting surface of the medium abutting guide are formed. Since there is a step between them, even if there is a gap between the medium transport abutting guide and the lower guide, the edge of the medium should enter the contact surface between the medium transport abutting guide and the lower guide. Transported without. Therefore, according to the present invention, bending of the medium, tearing of the medium, and jamming or other defective conveyance of the medium do not occur.

[0011]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. Note that the same reference numerals are given to elements common to each drawing.

FIG. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a detailed view corresponding to the portion A of FIG. 4 in this embodiment, and FIG. 3 is a sectional view taken along the line DD 'of FIG.

The present embodiment is different from the conventional example in that a step is provided between the contact surface between the lower guide and the medium conveying abutting guide and the medium abutting surface of the medium conveying abutting guide.

In FIG. 1, the abutting guide 10 is provided with a step portion 32 having a step 31 with respect to the side wall 13 as shown in FIG. The lower guide 11 has a shape along the step portion 32, and the lower guide 11 is abutted and fixed to the side portion 33 of the step portion 32. In FIG. 2, the upper guide 12 is brought into contact with and fixed to the upper guide abutting surface 14 of the abutting guide 10 as in the prior art. In this way, the abutment guide 10, the lower guide 11, and the upper guide 12 form the conveying path 4.

When the medium 9 is conveyed through the conveying path 4, the end portion 20 of the medium 9 abuts the medium abutting surface 34 of the abutting guide 10 as shown in FIG. Even if a gap 35 is formed at the contact portion between the abutting guide 10 and the lower guide 11 due to the same cause as in the conventional technique, the end portion 20 of the medium 9 is conveyed without entering the gap 35.

[0016]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

That is, since a step is provided between the contact surface between the lower guide and the medium conveying butting guide and the medium butting surface of the medium conveying butting guide, the medium is conveyed and ejected during medium ejection. Even if the edge hits the side wall of the medium conveyance abutting guide, it prevents bending of the medium in the conveying direction, breakage of the medium, jamming, and other medium conveyance defects, and improves the stability of conveyance and ejection.
