Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a reader / writer in which a microcomputer and a memory are incorporated in a plastic card and an IC card is manually input, and in particular, an IC card can be smoothly introduced into a main body of a read / write device mounted in a case. About what to do.
[0002]
[Prior art]
Generally, the edge of the card introduction portion into the card accommodation gap where the read / write portion of the electronic board in the reader / writer main body of the conventional IC card reader / writer extends linearly.
[0003]
[Problems to be solved by the invention]
Since the card introduction portion edge extends linearly, when the IC card is curved, the leading edge surface of the IC card and the introduction opening edge surface are in linear contact with each other to enter the card accommodation gap. There was a disadvantage that the introduction of the IC card was easily hindered. An object of the present invention is to eliminate this inconvenience, and an object of the present invention is to provide an IC card reader / writer that solves this problem.
[0004]
[Means for Solving the Problems]
The reader / writer of the card of the present invention has a read / write device main body fixed in a case having a card insertion slot. The read / write device main body is provided with an electronic circuit, and has an electronic board having a read / write unit, and the card insertion slot. An IC card reader / writer which is formed by overlapping a card guide positioned corresponding to the card guide, and forms a card accommodation gap between the card guide accommodation plate and the electronic substrate. The receiving plate edge, which is the edge of the receiving gap, is configured to be recessed toward the back side of the card receiving gap.

DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. 1 is a perspective view of a reader / writer, FIG. 2 is a plan view of a read / write device body, FIG. 3 is a plan view of a card guide, FIG. 4 is a back view of the card guide, and FIG. 6 is a cross-sectional view taken along line BB in FIG. 3, FIG. 7 is a cross-sectional view taken along line CC in FIG. 3, FIG. 8 is a side view, and FIG. 9 is a cross-sectional view taken along line DD in FIG. 10 is a cross-sectional view taken along line EE in FIG. 3, and FIG. 11 is a cross-sectional view taken along line FF in FIG.
[0006]
As shown in FIGS. 1 and 2, a card reader / writer 1 has a read / write device body 4 fixed in a case 3 having a card insertion slot 2. The case 3 is configured such that the cover 3b is covered with the bottom 3a and fixed by a connecting member (not shown) provided on both sides, and the above-described card insertion is inserted into one end of the cover 3b. Mouth 2 is provided. Further, the bottom portion 3a and the cover body 3b are integrated with each other by sandwiching the fixed pieces 5 provided at the four corners of the read / write device main body 4 with screws.
[0007]
The read / write device body 4 guides the electronic board 6 on which an electric circuit is printed and a signal line 6a for connection to a terminal device (not shown) is connected, and an IC card 7 to be inserted. A card guide 9 configured so that a read / write data input / output unit (not shown) is positioned corresponding to the read / write unit 8 of the first and second through holes 10 and 11 provided in the electronic board 6 and the card. The first locking claw 12 and the second locking claw 13 provided on the guide 9 are integrated.
[0008]
As shown in FIGS. 3 to 11, the card guide 9 corresponds to the edge 14 of the four sides, the guide plate 15 (side integrated with the electronic substrate 5), the receiving plate 16, and both sides of the guide plate 15. The guide plate 15 and the belt-like guide 17 provided at a predetermined interval are integrally formed by plastic molding. When the electronic substrate 6 is overlapped and integrated with the card guide 9 to form the read / write device body 4, a card accommodation gap 18 into which a card can be inserted is formed between the accommodation plate 16 and the electronic substrate 6.
[0009]
The introduction portion for introducing the IC card 7 into the card accommodation gap 18 is constituted by a gap between the accommodation plate edge 16a and the guide plate 15 edge, and the accommodation plate edge 16a is located on the back side of the card accommodation gap 18. It is formed in a circular arc shape that is recessed toward. Thus, by forming the receiving plate edge 16a into a concave arc shape, the leading edge of the IC card 7 to be introduced makes point contact with two points of the receiving plate edge 16a. The IC card 7 is smoothly introduced into the card accommodation gap 18 without the tip edge of 7 and the edge of the accommodation plate edge 16a being in linear contact.
[0010]
As shown in FIGS. 3, 4, 6, 9, and 11, the end portion of the IC card 7 that enters the card guide 9 is placed inside the opposing edge portion 14 of the card accommodation gap 18. A pair of side guide pieces 19 are provided so that they can be guided sideways. When both sides of the IC card 7 entering between the accommodation plate 16 and the electronic substrate 6 are bent toward the accommodation plate 16, the side guide pieces 19 are pressed toward the accommodation plate 16 and the shape is changed to a plane. Then, it enters between the accommodation plate 16 and the electronic substrate 6.
[0011]
Further, the leading ends of the guide plate 15 and the belt-like guide 17 are formed on inclined surfaces that become thinner toward the outside so that the IC card 7 can easily enter, and the card insertion slot 2 when fixed to the case 3. It is configured to correspond to
[0012]
As shown in FIGS. 2, 3, 5, and 7, the card guide 9 has a convex portion 20 that is positioned near the back of the receiving plate 16 and is pressed against the read / write unit 8 of the electronic substrate 6. Form. Then, the data input / output part (not shown) of the IC card 6 introduced into the card accommodation gap 18 between the accommodation plate 16 and the electronic board 6 abuts on the read / write part 8 of the electronic board 6 to read / write data. Write.
[0013]
Each of the first locking claws 12 protrudes from the edge 14 of the card guide 9 and is provided with a bent edge 21 at the tip, and U-shaped cuts 22 and 22 are formed in the edge 14 near both sides thereof. Is provided. Each of the other second locking claws 13 protrudes on the guide plate 15 substantially at the center of the card guide 9 and has a bent edge 23 at the tip. The bent edge 21 of the first locking claw 12 and the bent edge 23 of the second locking claw 13 are projected so as to face each other.
[0014]
In order to integrate the electronic board 6 and the card guide 9 (to constitute the read / write device main body 4), the first through holes 10, the first locking claws 12, and the second through holes 11 Each 2nd latching claw 13 is made to correspond, and each latching claw 12,13 is inserted in each through-hole 10,11. During the insertion, the bent edges 21 and 23 are pushed outward by the inner edges of the first and second through holes 10 and 11, and the first and second locking claws 12 and 13 are bent outward. Get over the inner edge of each of the first and second through holes 10 and 11. Thus, when the bent edges 21 and 23 get over the inner edges of the first and second through holes 10 and 11, the bent edges 21 and 23 are locked to the inner edges, and the electronic board 6 And the card guide 9 are fixed.
[0015]
Note that the present invention is not limited to the above-described embodiment. For example, the receiving plate edge 16a is not formed in an arc shape recessed toward the back side of the card receiving gap 18, but the card receiving gap 18 is formed. It is good also as a shape dented in V shape toward the back side. Furthermore, the reading / writing of the read / write data of the IC card 7 may be performed in a non-contact state between the read / write contact of the electronic substrate 6 and the read / write data input / output unit of the IC card 7.
[0016]
【Effect of the invention】
As described above, since the reader / writer of the IC card of the present invention is formed in a shape in which the receiving plate edge is recessed, the tip edge of the inserted IC card is in point contact with only two points of the receiving plate edge, Unlike the prior art, the leading edge of the IC card and the edge of the receiving plate are not in surface contact, and the IC card is smoothly introduced into the card receiving gap.
