  In such a structure in which two bundled thin cords are passed through the mounting holes provided in the housing, it is very troublesome to pass the cords regardless of the type of portable device such as a folding type, an integrated type, and a sliding type. It was troublesome. Further, depending on the opening area of the attachment hole (for example, if the opening area is too small), the thin string is difficult to reach the outlet completely. For this reason, it has often been seen that the thin string is pulled up (guided) to the outlet opening with a bar-like tip such as a pen tip.

  In addition, there are various straps on the market, and the diameter and material (stiffness) of the thin string are various. For example, if the diameter of the thin string is too thick or the material is too soft for the size and length of the mounting hole, it may be difficult to reach the outlet of the mounting hole. In addition, in such an insertion structure, in order to fix the strap, it is necessary to pass the thin string after insertion through the strap again. On the contrary, if the material is too hard, it is difficult to fix the strap. There is. Recently, there are many users who attach a plurality of straps to one strap attaching portion, and when attaching many straps, it becomes more difficult to reach the outlet of the attaching hole.

  On the other hand, when paying attention to the shape of the hand strap attachment structure on the housing side, a general mold structure for forming an attachment hole having two openings is more complicated than a normal mold structure. Further, as the strap attachment portion 99 shown in FIG. 13, the appearance of the strap attachment structure becomes a projection shape, which deteriorates the appearance and becomes a negative element for the appearance.

  Moreover, in the hand strap attachment structure with which the portable terminal device of patent document 1 is provided, it is possible to attach easily by making it the structure which hooks a strap string inside a housing | casing. However, in the structure in which the strap is held by hooking the strap attachment portion 46 having a circular cross section, the strap may not be completely held depending on the direction and strength of the force applied to the hand strap. is there. Although Patent Document 1 shows a structure for preventing the strap attachment part 46 from being detached, the structure for providing the bent part 62 is complicated, and a fitting groove is provided in the battery lid 34. In the case of the structure provided, there is a possibility that it cannot be applied to the slide type.

  Accordingly, the present invention provides a strap attachment structure and a portable device that can be easily attached and detached without distinguishing straps having various characteristics and can hold the strap more firmly. With the goal.

In the side wall portion of the rear housing 3, two cutout openings 6-2 for guiding the thin string 5-1 fitted in the U-shaped groove 6-1 to the outside are formed.

  In addition, the shape of the U-shaped groove 6-1 does not necessarily need to be U-shaped, and when the end of the annular thin string 5-1 is stored, the thin string 5-1 is not affected by the tension in the opening direction. For example, a U-shape may be used as long as it can be hooked. In addition, the hand strap attaching portion 6 does not necessarily have to be provided with a groove, and the thin string 5-1 is formed inside the U-shaped recess provided in the rear housing 3 with respect to the U-shaped recess. The U-shaped groove 6-1 may be formed by fitting a U-shaped part smaller than the diameter. Hereinafter, the site | part inside the U-shaped groove | channel 6-1 may be expressed as the hand strap attachment part (inward) 3-1. Similarly, a portion outside the U-shaped groove 6-1 may be expressed as a hand strap attachment portion (outside) 3-2.

  In the present embodiment, as shown in FIGS. 4 to 6, in order to hold the hand strap 5 more firmly, the battery cover 4 has a U-shape when the battery cover 4 is attached to the rear housing 3. A thin string presser rib 4-4 is provided so as to enter the groove 6-1. The thin string pressing rib 4-4 is more preferably provided at a position corresponding to at least the groove of the notch opening 6-2 in consideration of the external force applied to the thin string 5-1. . When the mobile terminal device 1 slides and attaches the battery cover 4, a groove corresponding to at least the slide width is provided from the notch opening 6-2 so as to be parallel to the sliding direction, and the groove is parallel. What is necessary is just to arrange | position the string holding rib 4-4 in the position corresponding to.

  Next, a method for attaching the strap will be described. FIG. 7 is a cross-sectional view (cross-sectional view taken along line A-A ′ in FIG. 1) of the hand strap attachment portion 6 cut along a plane parallel to the longitudinal direction of the mobile terminal device 1. Fig.7 (a) is sectional drawing of the hand strap attachment part 6 of the state which mounted | wore with the hand strap. FIG.7 (b) is a fragmentary sectional view of the hand strap attachment part 6 (b part) in the state which mounted | wore with the hand strap. FIG.7 (c) is a fragmentary sectional view of the hand strap attachment part 6 (b part) in the state which mounted | wore with multiple hand straps. First, in order to attach the hand strap 5 to the mobile terminal device 1, the battery cover 4 must be in a state of being detached from the mobile terminal device 1 (main device). From this state, the user drops (inserts) the thin string 5-1 of the hand strap 5 into the U-shaped groove 6-1 of the hand strap attachment portion 6 provided in the rear housing 3. If the battery cover 4 is attached to the main body device in this state, the process is completed. In addition, what is necessary is just to reverse this operation | movement when removing a hand strap. As shown in FIG. 7C, a plurality of straps can be hooked (hanged and stopped) by increasing the depth of the U-shaped groove 6-1.

  In a state where the battery cover 4 is attached to the rear housing 3, the battery cover 4 is in a state of covering the hand strap attachment portion 6, so that the thin string 5-1 of the hand strap 5 jumps out of the U-shaped groove 6-1. (Does not come off). Originally, the battery cover functions to prevent the battery from falling off due to a drop collision, but in the present embodiment, the battery cover also functions as a cover lid for preventing the hand strap 5 from being detached.

  Even if a strong force is applied to the hand strap 5 in the direction in which the thin string 5-1 is pulled out from the U-shaped groove 6-1 (rear housing side), the fixing hook (lower part 4-3) of the battery cover 4 is applied. As long as the hook hooking portion (lower portion 3-3) of the rear housing 3 is fitted, the hand strap 5 does not come off from the U-shaped groove 6-1.

  In consideration of the ability of the thin string 5-1 to withstand the force of pulling out of the U-shaped groove 6-1, it is more desirable that a part of the fixing hook is disposed on both sides of the hand strap attachment portion 6.

  The battery cover 4 desirably covers all of the U-shaped groove 6-1. For example, when the battery cover 4 has a mountain shape and contacts only the side wall portion of the rear housing 3, as shown in FIG. 7, the hand strap attachment portion (inward) 3-1 and the hand strap attachment portion (Outside) The height of 3-2 may be increased according to the battery cover 4. Further, even if the entire U-shaped groove 6-1 is not covered, for example, the thin string pressing rib 4-4 is provided at a position corresponding to a total of three locations of the opening and the center of the U-shaped groove 6-1, By adjusting the number and position of the thin string pressing ribs 4-4, the role of the lid can be sufficiently achieved.

  As described above, according to the present embodiment, the hand cover can be removed by simply removing the battery cover and fitting the hand strap into the U-shaped groove 6-1 without assembling a dedicated hand strap attachment part in the housing or the like. The strap can be easily attached and detached. In addition, in the present invention, the string can be moved by fitting the string in the U-shaped groove 6-1 as compared with the structure in which the protrusion shape and the cap are brought into close contact with each other and the string is hooked. The area can be reduced. Therefore, the string can be held more firmly. Moreover, since the movable range of the string in the opening can be further reduced by providing the thin string pressing rib 4-4 in the vicinity of the opening, against the external force on the opening, such as vibration of the hand strap 5, Further, the string can be held firmly.

  Further, in terms of appearance, most of the hand strap attachment structure is covered with the battery cover, so that the design impact (grooves and holes exposed to the appearance) can be minimized. In addition, the exposed hole can also be made into one thin string, and a more excellent external appearance can be maintained compared with the conventional design impact.

  On the other hand, the number of straps that can be hooked can be increased according to the depth of the U-shaped groove 6-1, so that more hand straps can be attached than ever. Even if a plurality of hand straps are hooked, they can be securely held, and the attachment method does not become difficult due to an increase in the number of hand straps.

Embodiment 2. FIG.
The second embodiment of the present invention will be described below with reference to the drawings.

In the present embodiment, as shown in FIGS. 8 and 9, the removal preventing protrusion 6-3 is a U-shaped substantially central portion, and has an inner sidewall of the U-shaped groove 6-1 (ie, hand strap attachment). A protrusion is provided at the cover side end of the portion (inside) 3-1. Note that the amount of protrusion of the drop prevention protrusion 6-3 is set such that the width of the U-shaped groove 6-1 is smaller than the diameter of the thin string 5-1 of the hand strap 5.

  For this reason, when attaching and detaching the thin string 5-1, the thin string is slightly crushed and press-fitted (pressed with pressure). However, according to the present embodiment, even if the battery cover 4 is not attached, the thin string 5-1 cannot be easily detached from the U-shaped groove 6-1, and in particular, a plurality of straps are mounted. It can be predicted that the convenience of the users who are present will improve. Note that the escape prevention protrusion 6-3 is not limited to the substantially central portion of the U-shape of the U-shaped groove 6-1, but may be provided other than the substantially central portion or a plurality of the protrusion prevention projections 6-3. For example, it is also conceivable to provide two positions that approach the curve from the U-shaped opening.

  Further, it is conceivable that when the thin string 5-1 is first fitted into the U-shaped groove 6-1, it becomes difficult to be caught by the drop preventing protrusion 6-3 by providing the drop preventing protrusion 6-3. . In such a case, the bottom surface area of the U-shaped groove 6-1 is provided by, for example, providing a mounting portion guide 7 that fixes the hand strap mounting portion (inward) 3-1 from the inside of the rear housing 3.
