The acute inclination angle (angle α) of the hook-shaped protrusion 8e1 and the acute inclination angle (angle γ) of the first locking portion 11e1 with respect to the tongue piece 8c are configured to be substantially the same. .

  Further, as shown in FIG. 4, the protruding piece 8e is formed so that the width t in the thickness direction of the tongue piece 8c is longer than the minimum gap interval c of the storage gap 9. When inserting the tongue piece 8c into the gap 9, the acute angle of inclination of the first protrusion 8e1 with respect to the tongue 8c is reduced and the obtuse angle of the second protrusion 8e2 with respect to the tongue 8c. The inclination angle is increased.

  Furthermore, as shown in FIGS. 3 and 4, a relief portion 8 f with a reduced thickness is formed at a position of the tongue piece portion 8 c where the first projecting piece portion 8 e 1 faces. When the protruding piece 8e and the tongue piece 8c are inserted, the first protruding piece 8e1 is easily bent and the first protruding piece 8e1 enters the escape portion 8f so that the thickness of the tongue piece 8c is increased. The width of the projecting piece 8e can be reduced.

  Further, as shown in FIGS. 3 and 4, the protruding piece 8 e and the tongue piece 8 c can be easily inserted and the tongue piece 8 c is accommodated on the opening 7 side of the first locking portion 11 e 1. A concave portion 12 is provided in the opening 7 so as to be smoothly recessed adjacent to the first projecting piece 8e1 so that the bent portion 8g of the tongue piece 8c is accommodated when being drawn out from the gap 9.

When inserted into 9, the U-shaped portion is elastically deformed in the width direction of the lower housing 2b (the left-right direction in FIG. 5), the minimum gap c is widened, and the protruding piece 8e can be easily inserted. It is like that. The back case 2b2 is provided with a protruding portion 13 that protrudes toward the storage gap 9 when joined to the key case 2b1, and the tongue piece 8c is positioned at the storage gap 9. In this case, the protrusion 13 restricts movement in the thickness direction (upward in FIG. 5).

  Further, the tongue piece portion 8c has a substantially constant thickness width, and the bent portion 8g protrudes and curves so as to face the inner surface side of the cover body 8a. Therefore, the inner surface side of the cover body 8a in the bent portion 8g is formed in a curved surface shape.

  Next, the operation of the illustrated example will be described.

  In the manufacturing process of the portable electronic device 1, after various inspections are performed using the interface connector, the cover member 8 is attached to the opening 7 formed in the lower housing 2 b of the portable electronic device main body 1 in the final step. In such a case, the tongue piece portion 8c formed with the protruding piece portion 8e having the first protruding piece portion 8e1 and the second protruding piece portion 8e2 is inserted into the storage gap portion 9, but the first protruding piece portion The tip shape of the tongue piece portion 8c formed with the protruding piece portion 8e having the 8e1 and the second protruding piece portion 8e2 is a shape in which the T-shape is inclined to the I-shape, It becomes easy to deform.

  In addition, when the tongue piece 8c formed with the protruding piece 8e is inserted into the storage gap 9, the acute inclination angle of the first protruding piece 8e1 with respect to the tongue piece 8c is reduced and the The projecting piece 8e bends so that the obtuse inclination angle of the second projecting piece 8e2 with respect to the tongue piece 8c increases, and the first projecting piece 8e1 bends and enters the escape portion 8f. The width t of the projecting piece 8e in the thickness direction of 8c can be reduced, and in addition to this, the opening 7 side of the first locking portion 11e1 can be smoothly smoothed as shown in FIGS. 5. A concave portion 12 having a concave shape is provided. Further, as shown in FIG. 5, a direction in which an inlet portion having a minimum gap interval c of the storage gap portion 9 having a U-shaped cross-sectional shape opened to the back side is widened. For example, the tongue piece 8c of the protruding piece 8e is elastically deformed. Also the width t in the direction of longer than the minimum gap spacing c of the receiving gap portion 9, it is easy to insert the tongue portion 8c to the housing gap portion 9.

  And after inserting the tongue piece part 8c in which the said protruding piece part 8e was formed in the accommodation gap | interval part 9, the 1st protruding piece part 8e1 and the 2nd protruding piece part 8e2 return to the original form, but here Since the tongue piece 8c is shaped to warp the outer surface of the cover body 8a, when the cover member 8 is fitted to the key side case 2b1, the tongue piece 8c and the projecting piece 8e. Is located on the outer peripheral side of the inside of the key side case 2b1, and it is not necessary to expand the storage space of the tongue piece 8c, and it is possible to make it compact.

  When the tongue piece portion 8c is further inserted into the storage gap portion 9, the bent portion 8g of the tongue piece portion 8c is accommodated in the recess 12 and movement is restricted. Therefore, in this state, the tongue piece 8c is positioned in the storage gap 9.

  Further, when the tongue piece 8c is pushed into the storage gap 9 with a predetermined force or more, the tongue piece 8c is elastically deformed due to its flexibility, and moves over the first locking portion 11e1. Then, the cover body 8a is pushed into the opening 7, and the claw 8d of the cover main body 8a is engaged with the claw receiving recess of the lower housing 2b so that the cover member 8 is housed in the lower housing 2b and integrated. It can be made.

  On the other hand, while the cover body 8a is moved in the direction in which the tongue piece 8c is pulled out toward the opening 7 along the storage gap 9, the tongue piece 8c is bent to move the cover body 8a to the portable electronic device. When the opening 7 is opened so as to be separated from the lower housing 2b of the device body 1, first, the bent portion 8g of the tongue piece portion 8c is deformed to get over the first locking portion 11e1 and enter the recess 12. Housed inside. At this time, the bent portion 8g protrudes and curves toward the inner surface side of the cover main body 8a, and at least the inner surface of the cover main body 8a of the bent portion 8g is formed in a curved shape. By pulling on, it is possible to get over the first locking portion 11e1 and to give a click feeling.

  And since the tongue piece part 8c is accommodated in the recessed part 12, the movement of the tongue piece part 8c is controlled and can be positioned in the accommodation space. That is, since the cover body 8a is formed in a bent state with respect to the tongue piece 8c, when the cover body 8a is pulled out from the opening 7, the cover body 8a is opened by the elastic restoring force of the tongue piece 8c. Positioning can be performed in an open state separated from. Therefore, the user can easily grasp the cover main body 8a, and the cover member 8 can be easily handled. When the cable connecting portion is arranged in the lower housing 2b and the cable connecting surface is arranged in the opening 7, The interface connector connection workability can be greatly improved, and the card insertion workability can be improved when the card insertion portion is arranged in the lower housing 2b and the card insertion slot is arranged in the opening 7. It can be greatly improved.

  When the tongue piece 8c is further moved so as to be pulled out from the storage gap 9, the first protruding piece 8e1 and the second protruding piece 8e2 are connected to the first locking portion 11e1 and the first engaging portion 11e1, as shown in FIG. It latches to the two latching | locking part 11e2.

  From this state, when the cover member 8 is pulled in the pulling direction, the first projecting piece 8e1 is in pressure contact with the first locking portion 11e1, and receives a counterclockwise reaction force in FIG. A force in the counterclockwise direction in FIG. 4 also acts on the second protrusion piece 8e2, and the second protrusion piece 8e2 is pressed against the second locking portion 11e2.

  As a result, even if the cover member 8 is pulled in the pulling direction, the first protruding piece 8e1 and the second protruding piece 8e2 bite into the first locking portion 11e1 and the second locking portion 11e2, respectively. The cover member 8 is strongly hooked in a direction that prevents the cover member 8 from being pulled out, and cannot easily be removed.

  In this way, the tongue piece 8c can be easily inserted into the storage gap 9 and can be made difficult to remove without being affected by design restrictions, the position of the opening 7, and the like.

  Note that the case body and the portable electronic device having the cover member of the present invention are not limited to the illustrated examples described above, and it is needless to say that various modifications can be made without departing from the gist of the present invention. .

  For example, the first locking portion 11e1 that locks the first protruding piece portion 8e1 is formed to be inclined at an acute angle with respect to the tongue piece portion 8c, and the first protruding piece portion 8e1 with respect to the tongue piece portion 8c. Although it is configured to have an acute inclination angle (angle γ) that is substantially the same as the acute inclination angle (angle α), the first locking portion 11e1 is not limited to this configuration, and the first locking portion 11e1 is a cover member. If the tongue piece 8c is slid in the direction in which the tongue piece 8c is pulled out toward the opening 7 along the storage gap 9 and pulled in the pulling direction, the first protruding piece 8e1 is locked. good. Moreover, the 2nd latching | locking part 11e2 should just be a structure which latches the 2nd protrusion piece part 8e2 when it pulls in the direction which pulls out the cover member 8. FIG. Furthermore, for example, the second locking portion 11e2 may be shaped along the tongue piece portion 8c and the second projecting piece portion 8e2.

  Further, when the cover member 8 is pulled in the pulling direction, the first protruding piece 8e1 and the second protruding piece 8e2 are simultaneously locked to the first locking portion 11e1 and the second locking portion 11e2, respectively. However, before the second protruding piece 8e2 is locked to the second locking portion 11e2, the first protruding piece 8e1 is first locked to the first locking portion 11e1, and the hook-shaped protruding piece 8e1. After the cover member 8 is further pulled out from the state of being pressed against the first locking portion 11e1 and a counterclockwise force is applied to the second protruding piece portion 8e2, the second protruding piece portion 8e2 is locked into the second locking portion. You may comprise so that it may press-contact to the part 11e2.
