Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a passage forming guide for a card reader or the like which has improved dimensional accuracy of a passage width of a card or the like.

(Prior art)

Conventionally, to form the card running path 7, the left and right side plates 1, 2 are held at equal intervals by upper and lower columns 3, 4 as shown in FIGS. The upper and lower guide plates 5 and 6 are attached, and as the mounting structure, screw holes 8b and 8b are formed in the guide plates 5 and 6 by screws 8 and 8 passing through the fool holes 1a and 2a of the left and right side plates 1 and 2. Screwed to 5e, 6e.

When the card running path is formed as described above, the interval between the side plates 1 and 2, that is, the length of the columns 3 and 4 and the width of the guide plates 5 and 6 do not match due to variations in the bending dimensions of the guide plates. . For this reason, the width of the guide traveling path 7 becomes inaccurate.
Also, since the dimensions do not match, the side plates 1, 2 or the guide plates 5, 6
Is distorted. Since the bending dimensions of the guide plates 5 and 6 must be strictly controlled, there are disadvantages such as an increase in cost.

[Purpose of the invention]

In view of the above drawbacks, the present invention makes it possible to accurately set the distance between the side plates, that is, the width of the card running path to the length of the support column, to increase the bending tolerance of the guide plate, and to prevent the side plate and the guide plate from being distorted. It is to propose a guide for forming a passage such as a card reader.

[Structure of device]

In the present invention, a pair of side plates are held in parallel by a column, and a pair of guide plates facing each other with bent ends on both ends are disposed between the side plates to form a passage for a card reader or the like. In the forming guide, one bent piece of each of the pair of guide plates is screwed and fixed to this side plate through a hole provided in one side plate and longer in the longitudinal direction than the screw diameter, and the other bent piece is formed. In this method, a hole having a length substantially equal to the width of the protrusion in the vertical direction is formed with respect to the protrusion made of a screw screwed to the other side plate, and this hole is fitted to the protrusion made of the screw.

〔Example〕

Hereinafter, the present invention will be described with reference to the illustrated embodiments. In this passage forming guide such as a card reader, left and right side plates 1 and 2 are held in parallel by upper and lower columns 3 and 4 in FIGS. Upper and lower guide plates 5 and 6 are attached to the left and right side plates 1 and 2 to form a card passage 7.

The mounting structure of the upper and lower guide plates 5 and 6 to the left and right side plates 1 and 2 is such that the one side plate 1 side is provided with a vertical fool hole 1a, that is, a screw 8 in one side plate 1 as shown in FIGS. A hole 1a that is longer than the diameter in the vertical direction is drilled, a screw 8 is passed through, and a screw is formed by drilling a hole in one of the bent pieces 5a, 6a of the upper and lower guide plates 5, 6. A screw 8 is screwed into the holes 5b and 6b and fixed.

On the other side plate 2 side, as shown in FIGS. 1 and 4, a hole is formed in the other side plate 2 and a screw hole 2a in which a screw is carved is formed. Combined, upper and lower guide plate
Projections 9 made of a screw are passed through holes 5d, 6d formed in the other bent pieces 5c, 6c of substantially the same width as the projections 9 and longer than the projections 9 in the longitudinal direction.

The interval between the upper and lower guide plates 5 and 6 is determined by the clearance between the long longitudinal hole 1a and the screw 8 formed in one side plate 1 and the other bent piece 5c and 6c of the upper and lower guide plates 5 and 6. Drilled projection 9
It is adjusted by holes 5d and 6d which are approximately the same width as the above and which are long in the vertical direction. on the other hand,
The upper and lower guide plates 5 and 6 cannot move in the card running direction.

Upper and lower guide plates with screws 8 on one side plate 1 as described above
One of the bent pieces 5a, 6a is fixed, and the other side plate 2 is provided with a projection 9, and the bent pieces 5 of the upper and lower guide plates 5, 6 are fixed.
Since the protrusions 9 were passed through the holes 5d and 6d which are long in the vertical direction of c and 6c,
Even if the bending dimensions of the bent pieces 5a, 6a, 5c, 6c of the upper and lower guide plates 5, 6 vary, the spacing between the side plates 1, 2
If the lengths of the guide plates 5 and 6 are shorter than the lengths of the lengths 3 and 4, the width of the card running path 7 can be accurately determined. In addition, the bending tolerance of the guide plates 5 and 6 can be increased, the cost can be reduced, and the cost is reduced.
No distortion occurs in 5,6. Furthermore, by removing the screws 8 and 9 on both sides, the guide plates can be
Only 5 and 6 can be removed, and disassembly and assemblability as a device such as a card reader can be improved.

A longitudinally long hole formed in the one side plate 1 is provided.
1a may not be a long hole, but may be a circular hole having substantially the same shape as the screw 8 having some clearance with the screw 8.

[Effect of the invention]

Since the present invention is configured as described above, even if there is variation in the bending dimensions of the bent pieces of the upper and lower guide plates, if the interval between the side plates, that is, shorter than the length of the column, the width of the card running path is reduced. It is possible to provide accurate effects, increase the bending tolerance of the guide plate, and produce practically excellent effects such as disassembling and assembling the passage easily by not distorting the side plate and the guide plate and making the protrusions screws. A guide for forming a passage such as a card reader can be provided.
