Description of the invention (3) Advance and retreat 'and hold the lid in a closed state by engaging the end of the lid. The engaging member has an engaging portion main body that engages the end of the cover, and an advancing mechanism that advances the main body in the forward and retracting directions, and both the engaging portion main body and the advancing mechanism are integrally formed. Since this integral structure 'the engaging portion main body and the propulsion mechanism can be attached only by mounting the engaging member on the casing main body, this greatly simplifies the assembly operation. Such a case can be used for entertainment devices, such as a CD or DVD player or a game device, and the use of the structure of the present invention on these electronic devices can simplify the structure of the case. 'This makes the electronic device smaller and lighter and It is desirable to reduce its cost. The propulsion mechanism should preferably have a symmetrical structure for distributing a uniform force on the engaging members, and should be formed into a ring shape. It is also suitable that a guide member is provided on the main body of the casing to adjust the movement of the main body of the engaging portion. It is also suitable to construct the meshing member as a one-piece injection molded polyacetal, because polyacetal is a good sliding material and has good fatigue strength. It is also suitable to form an opening for the cover to press fit in the main body of the casing, and to provide a recess on the peripheral edge of the opening, so that in the state that the cover is press fitted into the opening, the peripheral edge of the cover is exposed to the outside of the recess . The casing main body is also suitable for having a pair of accommodating members or casing halves which internally accommodate a device main body having electronic components and the like by interengaging, and is also suitable for forming an exposed portion of the casing main body provided on the device main body. An opening portion of a connection terminal connected to an external device, and the opening portion is suitable to cross a boundary portion of the pair of receiving members. Here, the connection terminals for external device connection may include but are not subject to the Chinese national standard (CNS) A4 specification (210 X 297 mm) for this paper size (please read the precautions on the back first to write this page)

Description of the invention (4) Limited to, for example, the controller connector (terminal) connected to the controller, and used to output signals from the device main body to the television receiver Video output terminals of the device, and power terminals for supplying power from an external power source to the device body. Also, the opening portion that crosses the boundary portion (engagement line) of the pair of accommodating members may include, but is not limited to, an opening portion formed by, for example, an opening formed in each of the pair of accommodating members that faces the boundary portion. And an opening portion formed by an opening formed in one or the other of the pair of accommodating members facing a boundary portion, and the like. Therefore, the pair of accommodating members constituting the main body of the cabinet is normally formed by injection molding using a metal mold having an upper mold (cavity) and a lower mold (heart-shaped). With this, if, for example, an opening portion of a receiving member exposed to a connection terminal provided on a main body of the device is to be formed, the receiving member is formed by (1) a sliding heart shape that engages the upper mold and the lower mold and moves horizontally. Insert into the metal mold, (2) inject the resin into the metal mold, (3) move the sliding heart shape and remove it from the inside of the metal mold, and (4) raise the upper mold and separate the molded part from the mold. However, this must have the additional step of moving the sliding heart shape, which causes a problem of reducing the productivity of the receiving member. Therefore, if the opening portion is formed to cross the boundary portion of the pair of accommodating members instead of forming the opening portion inside the accommodating member, as long as the opening facing the boundary portion is formed in each accommodating member, no sliding is required. Heart-shaped, reduces the number of manufacturing steps, and thus improves the productivity of the receiving member.

Description of the invention (11) (Please read the notes on the back first to write this page) Mobile printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. An inclined surface 27A is formed on the tip of the upper portion 27 of the main body, and it is inclined downward toward the middle portion of the disc mounting portion 20 (see FIG. 4). The tip of the inclined surface 27A protrudes into the disc mounting portion 20 when the button 16 is not pressed down and is pushed toward the disc mounting portion 20 by the pushing mechanism 26. In this manner, the cover 13 can be held in the closed state by the tip of the inclined surface 27A being engaged in the recess 2 1 C of the engaging member 2 1 B. The lower portion 28 of the main body is closely fitted in the opening 14C (FIG. 7). The opening 14C is formed in the upper case main body 14 and is substantially the same as the flat shape of the lower main body portion 28. This also adjusts the engagement in this manner. The movement of the member 24 is perpendicular to the forward and backward directions. The main body upper portion 27 and the lower body portion 28 are formed with substantially square through-holes 29 in their substantially middle portions, respectively. Of the inside surfaces forming the through-holes 29 and perpendicular to the longitudinal direction of the engaging portion main body 25, the inside surface formed on the side of the pushing mechanism 26 is an inclined surface 29A which is inclined toward the disc mounting portion 20. The contact portion 23B of the above-mentioned pressing member 23 is in contact with this inclined surface 29A (Fig. 4). Therefore, when the operator presses the pressing member 23, the inclined surface 29A is pressed by the contact portion 23B, and by the pressure applied to the inclined surface 29A, the engaging member 24 moves in a direction away from the engaging member 2 1B. In other words, the pressure caused by the pressing member 23 is converted into a force in the advancing and retracting direction of the engaging member 24 by the inclined surface 29A, thereby allowing the engaging member 24 to be separated from the engaging member 2 1B. The advancing mechanism 26 is formed in a ring shape in a plan view, and is formed and positioned symmetrically with respect to a center line along the longitudinal direction of the engaging member 24.

Description of the invention (12) (Please read the precautions on the back and write this page) The mechanism 26 maintains a predetermined elastic force between the engaging portion main body 25 and the receiving portion 1 4 D. When the operator removes his hand from the pressing portion 23A or closes the lid 13, the engaging member 24 automatically returns to its original position by the advancing mechanism 26, so that the lid 13 can be automatically engaged by the engaging member 24. The engaging member 24 fits the lower portion 28 of the main body tightly into the opening 1 4C in a state where the portion of the advancing mechanism 26 that is in contact with the receiving portion 1 4D is bent, and the upper case main body 1 4 is fitted after it is installed. It can be attached by releasing the bending of the propulsion mechanism 26 and engaging the propulsion mechanism 26 into the receiving portion 14D. The operation of opening and closing the cover 13 of this entertainment device 1 is as follows. First, when the cover 13 is closed (FIGS. 2 and 4), that is, if the tip of the inclined surface 27A of the upper portion 27 of the main body engages in the recess 2 1 C of the engaging member 2 1 B, when the operator depresses the pressing member At 23 o'clock, the contact portion 23 B of the pressing member 23 is inserted into the through hole 29 of the engaging portion main body 25 and is pressed against the inclined surface 2 9 A. The pressure exerted by the contact portion 2 3 B against the inclined surface 2 9 A causes the engaging member 24 to move in a direction away from the engaging member 21 B. In this way, the tip of the inclined surface 27 A of the upper part 27 of the main body is separated from the engaging member 21 B, and the cover 13 is released by the elastic force of the spring 14 A (FIG. 3).
