There is.

[0005]

However, according to the conventional telephone body structure as described above, the cover lid panel 3A and the holding frame 4A are provided from the inside of the front case 1a with the front case 1a and the lower case 1b disassembled. There was a problem that the assembly process was troublesome because it had to be fixed with mounting screws or the like.

In view of the problems of the conventional communication equipment structure as described above, an object of the present invention is to easily assemble an indicator and a cover lid panel to a front case regardless of the assembly process of the front case and the lower case. It is to obtain the communication equipment structure.

[0007]

In order to achieve this object, the present invention forms a cutout portion to which a retractable display capable of displaying a dial number or the like can be attached to a surface case of a communication device case. In a communication device structure in which the cutout portion is selectively covered with a cover lid panel, a fulcrum hole and a slot communicating with the fulcrum hole are formed on both sides of the base of the display and the cover lid panel, and these fulcrums A pair of opposed non-circular cross-section projections that can be inserted into the corresponding fulcrum holes through the slots are arranged on both inner side surfaces of the cutout portion corresponding to the holes, and the base of the indicator and the cover lid panel and the bottom surface of the cutout portion. Communication in which a segment tooth is provided on either one of the above, and a semi-fixed claw capable of keeping the segment tooth in a semi-fixed state is projected on the other of the base of the display and the cover lid panel and the bottom surface of the cutout portion. It proposes a vessel structure. In a preferred embodiment of the present invention described later, a pair of fixing claws protruding toward the cutout portion are integrally formed on both side surfaces of the tip end portion of the cover lid panel 3A, and the cutting claws corresponding to these fixing claws are formed. A structure in which a pair of fixing holes are formed on both inner side surfaces of the opening will be described.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the embodiments of the present invention will be described below with reference to FIGS.

FIG. 1 shows a resin-molded telephone case 1 (communication device case) according to the present invention. The telephone case 1 is composed of a front case 1a and a lower case 1b. The arrangement of the function button 5, the dial numeric keypad 6, the office line button 7, etc. is the same as in the conventional case. Then, a cutout portion 8 is formed in a part of the front surface case 1a, and the cover lid panel 3 and the liquid crystal display 2 are selectively attached to the position of the cutout portion 8 by attaching means described later. Become.

That is, fulcrum holes 9 serving as mounting fulcrums are formed on both side surfaces of the semi-cylindrical bases 2a and 3a of the liquid crystal display 2 and the cover lid panel 3, and the width L of these fulcrum holes 9 is formed. _One slot 10 is connected to each other, and a pair of non-circular cross-section projections 11 are opposed to the inner side surface of the cutout portion 8 corresponding to the fulcrum hole 9 in the width direction of the cutout portion 8. It is projected. Abraded surface 1 of the same non-circular cross-section projection 11 having an outer diameter slightly smaller than the diameter of the fulcrum hole 9.
Since the dimension L ₂ between 1a is made slightly smaller than the width L ₁ , each non-circular cross-section projection 11 can be introduced into the corresponding fulcrum hole 9 through the slot 10.

Further, on the outer peripheral surfaces of the bases 2a and 3a of the liquid crystal display 2 and the cover lid panel 3, there are formed segment teeth 13 which mesh with the semi-fixed claws 12 protruding from the bottom surface of the cutout portion 8. . Of course, the relationship between the semi-fixed claw 12 and the segment tooth 13 is that the segment tooth 13 is cut into the opening 8
Although the semi-fixed claw 12 may be provided on the bottom surface of the liquid crystal display 2 and the base portions 2a and 3a of the cover lid panel 3, as shown in FIGS. 9, the semi-fixed claw 12 meshes with one of the segment teeth 13 according to the inclination of the liquid crystal display 2 and the cover lid panel 3, so that the liquid crystal display 2 and the cover lid panel 3
Is placed in a semi-fixed state with the same inclination. The code "1"
4 "is the base portions 2a, 3 of the liquid crystal display 2 and the cover lid panel 3.
It is an arc-shaped guide for guiding a, and these arc-shaped guides 1
By the action of 4, the liquid crystal display 2 and the cover lid panel 3 are prevented from being easily pulled out from the protrusion 11 having the non-circular cross section.

Further, a pair of fixed claws 15 projecting toward the cut-out portion 8 are integrally formed on both side surfaces of the cover lid panel 3 near the front ends thereof, and face the front ends of these fixed claws 15. In addition, a pair of fixing holes 16 are formed on both inner side surfaces of the cutout portion 8. Therefore, when the fulcrum hole 9 of the cover lid panel 3 is passed through the protrusion 11 having a non-circular cross section, and the cover lid panel 3 is pressed downward toward the surface case 1a,
Since the fixing claws 15 of the cover lid panel 3 fall into the corresponding fixing holes 16 of the cutout portion 8, as shown in FIG.
The cover lid panel 3 is completely fixed to a, and it is prevented that the cover lid panel 3 is easily removed by an external force.

Since the telephone structure according to the illustrated embodiment has the above-described structure, the liquid crystal display 2 is assembled to the surface case 1a as shown in FIG. That is, when the non-circular cross-section projection 11 is introduced into the fulcrum hole 9 of the liquid crystal display 2 through the slot 10 and then the liquid crystal display 2 is rotated around the non-circular cross-section projection 11, the liquid crystal display from the surface case 1a is displayed. Although the device 2 does not come off, in this state, the semi-fixed claw 12 meshes with one of the segment teeth 13, so that the liquid crystal display 2 is placed in the same semi-fixed state by the semi-fixed claw 12. Therefore, as shown by the arrow B in FIG. 2, if the liquid crystal display 2 is angled about the non-circular cross-section protrusion 11, the liquid crystal display 2 can be freely adjusted to an angle at which it can be easily observed. Similarly, when the fulcrum hole 9 is introduced into the fulcrum hole 9 of the cover lid panel 3, the cover lid panel 3 cannot be removed from the surface case 1a, but as shown in FIG. When the lid panel 3 is tilted down and the cover lid panel 3 is pressed against the surface case 1a, the fixing claws 15 of the cover lid panel 3 fall into the fixing holes 16 on the inner side surface of the cutout portion 8, so that the cover lid panel 3 is removed. Can be completely fixed to. After all, in the telephone structure of the illustrated embodiment, not only a structure can be obtained in which the cover lid panel 3 or the liquid crystal display 2 is assembled to the surface case 1a independently of the lower case 1b, but also this assembly process requires no tools. It will not be needed.

In the above description of the embodiment, the case of the telephone case is illustrated, but it is pointed out again that the present invention can be applied to not only the telephone case but also other communication equipment structures. Needless to say.

[0015]

As is apparent from the above description, according to the present invention, the cover lid panel or the display can be easily assembled to the communication device case without using any tool. Since the process may be performed only on the surface case forming a part of the communication device case, there is an advantage that it is possible to easily respond to a specification change by a user and a request for adding a function later.
