Although there is a method of incorporating the cover 8 into the opening 7 of the lower housing 2b, in the following description including the present invention, the cover 8 is inserted into the rear case 12 as shown in FIG. The structure to be assembled will be described.

  FIG. 12 is a view of the cover 8 attached to the terminal device main body 1 from the inside. The cover 8 is a cover having a size covering the opening 7 of the storage medium 6 opened in the terminal device main body 1 of FIG. The main body 8a and a hinge portion 8c that extends integrally from one end side in the longitudinal direction of the cover main body 8a and includes a hook-shaped protruding piece portion 8b at the tip end portion. The cover body 8a is formed of a hard resin such as polycarbonate or ABS, and the hinge portion 8c having the hook-shaped protruding piece portion 8b is formed of a flexible material such as an elastomer. The main body 8a and the hinge portion 8c are integrated with each other by two-color molding or heat welding. The other end of the cover body 8a opposite to the hinge 8c is provided with a side claw 8d that can be engaged and disengaged on the side of the opening 7, and the cover body 8a A lower claw 8e that can be engaged and disengaged is provided on the bottom of the opening 7 on the lower side.

  As shown in FIG. 15, the terminal device main body 1 is formed with a hinge storage gap 14 extending adjacent to one end in the longitudinal direction of the opening 7 of the storage medium 6. Ribs 15 and 16 are provided at the end on the 7 side. The cover 8 is inserted and attached to the terminal device main body 1 from vertically above with respect to the paper surface of FIG. 15. At this time, the hook-shaped projecting piece 8b is inserted into the hinge storage gap 14; The hinge portion 8c is lightly press-fitted between the ribs 15 and 16. The rib 15 is configured to lock the hook-shaped projecting piece 8b, and restricts the hinge 8c from being pulled out to the opening 7 side. Further, as shown in FIGS. 13 and 14, the side of the opening 7 is an engaging portion 17 in which a side claw 8d provided on the cover body 8a is engaged and disengaged. As shown in FIG. 15, an engaging portion 18 is formed at the bottom surface of the opening 7. The engaging portion 18 is a groove portion that engages with a lower claw 8 e provided on the lower side of the cover body 8 a.

  In order to attach the cover 8 to the terminal device main body 1 so as to close the opening 7, the hinge 8c on one end side of the cover main body 8a in FIG. 12 is replaced with the hook-shaped protruding piece 8b as shown in FIGS. The hinge portion 8c is inserted between the ribs 15 and 16 in a light press-fit state so as to correspond to the hinge storage gap portion 14, while the side claw 8d on the other end side is engaged with the engaging portion 17 on the side of the opening 7. And the lower claw 8e provided on the lower side of the cover body 8a is engaged with the engaging portion 18 by the groove. As a result, the opening 7 is closed by the cover body 8a.

Slide in direction B. At this time, since the cover main body 8a is not restrained from moving vertically upward at right angles to the paper surface, the lower claw 8e can be easily pulled out of the engaging portion 18 by the groove portion. When the cover body 8a is moved away from the opening 7 so as to be bent in the direction, the opening 7 is opened.

For example, Patent Document 1 shows a structure in which an opening of a storage medium opened in the terminal device body is covered with a cover.
JP-A-10-190803

  Incidentally, the cover 8 shown in FIG. 11 is not completely fixed until the front case 9 and the rear case 12 are fitted in the manufacturing process, and the cover 8 is temporarily fixed to the rear case 12. It flows and is transported inside. In this temporarily fixed state, the hinge portion 8c of the cover body 8a is inserted between the ribs 15 and 16 of the hinge housing gap portion 14 in FIG. 15 and the side claw 8d is engaged with the engaging portion 17 on the side of the opening portion 7. The lower claw 8e is engaged with the engaging portion 18 by the groove portion, but is not sufficiently fixed in the A ′ direction in FIG. 17 which is opposite to the insertion direction A of the cover 8 shown in FIG. Moreover, it is conceivable that the cover 8 comes out of the terminal device body 1 (rear case 12). In order to cope with this problem and increase the fixing strength, it is conceivable to set the interval between the ribs 15 and 16 so that the hinge portion 8 c is press-fitted between the two ribs 15 and 16. However, if the press-fitting of the hinge portion 8c with respect to the ribs 15 and 16 is set too tight, there is a problem that the assemblability is deteriorated. There is a possibility that it cannot be kept in a sufficiently fixed state.

  Further, as shown in FIG. 16, when the cover 8 is slid in the B direction so as to open the opening 7, the side claw 8 d and the lower claw 8 e are connected to the engaging portions 17 and 18 of the terminal device body 1. Since it is released from the engagement, the cover 8 can easily fall down in the direction C of FIG. 16 and the restraining force is further weakened. Therefore, the cover 8 can easily fall off in the direction A ′ of FIG. There is a possibility.

  The present invention has been made in view of such circumstances, and intends to provide a cover structure of a terminal device that prevents the cover body from falling off the terminal device body and a terminal device including the cover structure. Is.
