【Example】

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view showing an external appearance of a card reader / writer 1 to which the present invention is applied. The card reader / writer 1 is placed, for example, next to a register in a department store or the like, and is suitable for use in exchanging information with a user of a prepaid card. On the front surface of the casing 2 of the card reader / writer 1, there is provided an operation unit 1a provided with a card insertion opening, an information display unit, a manual exclusion button, etc. And an information access head (not shown).

On the upper surface of the casing 2, as shown in FIG. 2, a lid 3 for maintenance and inspection of the card reader / writer 1 can be opened and closed upward as shown by an arrow A in the figure. It is provided. The lid 3 is made of, for example, a metal plate, and the rear end of the casing 2 is fixed to the base end of the casing 2 as shown in FIG. Is connected to the movable portion 4a of the hinge body 4. The fixed support portion 4b of the hinge body 4 is fixed to the bottom wall 2a as a casing body in an upright state. Between the fixed support portion 4b and the movable portion 4a, there is formed a thin wall portion 5 as an inverted U-shaped thin wall hinge that projects upward from the upper surface of the casing 2, and the fixed support portion 4b. On the other hand, the lid 3 is hinged so as to be tiltable.

By the way, a hinge cover 6 made of, for example, chloroprene rubber as an elastomer material is attached to the hinge body 4 so as to cover the surface of the thin portion 5 on the convex side. One end of the hinge cover 6 is adhesively fixed to the fixed support portion 4b of the hinge body 4, and the other end is fixed to the end portion of the lid body 3 on the hinge body 4 side and the movable portion 4a of the hinge body 4. It is adhesively fixed so as to be sandwiched between persons.

The fixed support portion 4 b of the hinge body 4 is covered with a metal rear cover 7 formed so as to cover the rear portion of the card reader / writer 1. The free end of the upper surface of the rear cover 7 is in close contact with the hinge cover 6, and the hinge cover 6 is sandwiched between the hinge body 4 and the rear cover 7. Further, the portion 6a that covers the convex portion of the thin wall portion 5 of the hinge cover 6 projects above the surface connecting the upper surface portion of the rear cover 7 and the upper surface of the lid body 3 in the closed state. A display unit 8 for displaying information read from the card is attached to the upper slope of the rear cover 7. Further, the rear cover 7 may be made of synthetic resin (for example, ABS resin).

In this way, the hinge cover 6 is attached so as to cover the surface of the thin portion 5 of the hinge body 4, and the thin portion 5 is white by repeatedly opening and closing the lid body 3 for maintenance and inspection. Even if it is made into a white shape, the white portion can be hidden by the hinge cover 6, so that the appearance is not spoiled. Furthermore, since the hinge cover 6 is attached so as to straddle the thin portion 5, the thin portion 5 can be reinforced, and the durability of the thin portion 5 of the hinge body 4 can be further improved. Moreover, the separation of the lid 3 can be prevented.

Further, as described above, one end of the rubber hinge cover 6 is sandwiched between the lid 3 and the movable portion 4a of the hinge body 4, and the rear cover 7 and the hinge body 4 are fixedly supported. Since the other end of the hinge cover 6 made of rubber is sandwiched between the casing 2 and 4b, the inside of the casing 2 is sealed from the outside. Therefore, it is possible to preferably prevent foreign matter such as dust and water from entering the casing 2 from the outside. Since the hinge cover 6 is made of chloroprene rubber, it can withstand use from a relatively low temperature to a high temperature (-15 ° C to 70 ° C).

Further, when the metallic lid 3 is opened, the end of the lid 3 and the rear cover 7 do not come into direct contact with each other due to the rubber hinge cover 6, and a squeak noise is generated. It can be preferably prevented. Similarly, since there is no direct contact between the end of the lid 3 and the rear cover 7, it is possible to prevent a slight damage due to the contact between the end of the lid 3 and the corresponding end of the rear cover 7.

FIG. 3 is a diagram corresponding to FIG. 2 showing a second embodiment according to the present invention. Similar parts are designated by the same reference numerals and detailed description thereof will be omitted. In the second embodiment, the thin portion 9 of the hinge body 4 has a shape recessed upward, and the portion 6a covering the thin portion 9 of the hinge cover 6 is the same as in the first embodiment. Further, it is bent in a convex shape upward so as to project above a surface connecting the upper surface of the rear cover 7 and the upper surface of the closed lid 3. Therefore, when the lid body 3 is tilted upward and opened, the convex portion of the hinge cover 6 is sandwiched between the lid body 3 and the rear cover 7. Also in the second embodiment, the same effect as that of the first embodiment is obtained.

Further, FIGS. 4 and 5 show third and fourth embodiments. Similar to the above, these figures are also figures corresponding to FIG. 2, and the same parts are denoted by the same reference numerals and detailed description thereof will be omitted. In the third embodiment shown in FIG. 4, the thin portion 10 has a shape recessed downward, and the portion 6b of the hinge cover 6 that covers the thin portion 10 is closed as described above. It is formed in a solid convex shape so as to project above the surface connecting the upper surface of the lid 3 and the upper surface of the rear cover 7 in the open state. In the third embodiment, since it is not necessary to bend the portion 6 of the hinge cover 6 that covers the thin portion 10 in a convex shape, the hinge cover 6 can be easily attached. Further, in the fourth embodiment shown in FIG. 5, the thin portion 11 has a shape symmetrically recessed in both the upper and lower directions, and the portion 6a of the hinge cover 6 which covers the thin portion 11 has the above-mentioned second portion. Similar to the embodiment described above, it is bent in a convex shape upward so as to project above the surface connecting the upper surface of the closed lid 3 and the upper surface of the rear cover 7. In each of these embodiments, the same effect as that of the first embodiment is obtained.

In the present embodiment, the casing of the card reader / writer is shown, but it can be applied to the hinge coupling portion of the lid in various casings using a hinge body made of synthetic resin.
