  Next, the cover part 30 is demonstrated using FIG.12 and FIG.13. FIG. 12 is a perspective view illustrating a schematic configuration of the cover portion, and FIG. 13 is a perspective view illustrating a schematic configuration of the cover portion. As shown in FIGS. 12 and 13, the cover portion 30 is a lid that covers the battery mounting portion 31 and the concave portion 40 on the back side of the rear case 22 </ b> B, and includes protrusions 72 and 74 and a cover claw portion 76.

  The protrusions 72 and 74 are protrusions provided at the end on the hinge part 4 side (opposite to the recess 40) in the longitudinal direction when the cover part 30 is mounted on the rear case 22B. The rear case 22B has insertion portions 78 and 79 into which the protrusions 72 and 74 are inserted. Note that the insertion portions 78 and 79 are recessed portions that are not connected to the sealed waterproof space of the second housing 22.

  The cover claw portion 76 is a claw provided at the end portion on the concave portion 40 side (the side opposite to the hinge portion 4) in the length direction when the cover portion 30 is attached to the rear case 22B. The cover claw portion 76 protrudes in the thickness direction when the cover portion 30 is attached to the rear case 22B, and the tip extends toward the hinge portion 4 side (projection portions 72 and 74 side) in the length direction. It is. The cover claw portion 76 has an L-shaped cross section orthogonal to the width direction. Moreover, the cover nail | claw part 76 is the shape (L-shape with fixed thickness) extended in the width direction. Further, the cover claw portion 76 has a length in the width direction substantially the same as or slightly smaller than the opening 60 of the connecting member 34.

  Next, a state where the cover portion 30 is fitted into the connecting member 34 and the concave portion 40 (the concave portion 40 in which the connecting member 34 is fitted) will be described with reference to FIGS. 14 is a cross-sectional perspective view showing the relationship between the second housing, the connecting member, and the cover portion, and FIG. 15 is a cross-sectional perspective view showing the relationship between the second housing, the connecting member, and the cover portion, FIG. 16 is a perspective view illustrating a relationship among the second housing, the connecting member, and the cover portion.

  The cover part 30 inserts the protrusion 72 into the insertion part 78 and inserts the protrusion 74 into the insertion part 79 to fix the end on the hinge part 4 side to the rear case 22B. The cover part 30 fixes the end part on the opposite side to the hinge part 4 to the rear case 22B by fitting (inserting) the cover claw part 76 into the recess 40 in which the connecting member 34 is fitted.

  Specifically, the cover claw portion 76 is engaged with the central claw portion 62 of the connecting member 34 by being inserted into the opening 60. Note that the cover claw portion 76 has a surface facing the cover portion 30 (a surface farthest from the bottom surface of the concave portion 40 of the claw protruding portion, a surface on the cover portion 30 side) facing the bottom surface of the concave portion 40 of the central claw portion 62. Facing the surface (the surface closest to the bottom surface of the concave portion 40 of the protrusion, the surface on the rear case 22B side) and in contact with the surface in this embodiment.

  The cover part 30 becomes a mechanism held by the connecting member 34 held by the rear case 22B by the cover claw part 76 engaging with the central claw part 62, and the cover part 30 is separated from the rear case 22B in the thickness direction. Even when a force to leave is applied, movement in the thickness direction is suppressed. In other words, the protrusions of the claw portion of the connecting member 34 and the claw portion of the cover portion 30 or the recess 40 of the rear case 22B are engaged, so that each portion has moved in a direction that is relatively separated in the thickness direction. In this case, since the claws facing each other are caught, it is possible to suppress the relative movement of each member in the thickness direction. Thereby, the cover part 30 is hold | maintained so that it may not remove | deviate from the rear case 22B.

  Moreover, the cover claw part 76 is arrange | positioned facing the surface on the opposite side to the surface in which the protrusion part is formed of the outer side claw part 58. FIG. The cover claw portion 76 and the outer claw portion 58 are disposed at a position closer to the protruding amount of the outer claw portion 58 in the width direction. As a result, when the outer claw portion 58 is deformed in the direction away from the housing claw portion 48, the outer claw is removed before the overlap between the protruding portions of the outer claw portion 58 and the housing claw portion 48 in the width direction becomes zero. The part 58 contacts the cover claw part 76. Accordingly, the outer claw portion 58 cannot be deformed to a position where the overlap of the protruding portion with the housing claw portion 48 becomes zero. Thereby, by attaching the cover part 30 to the rear case 22 </ b> B, the outer claw part 58 can be made difficult to come off from the housing claw part 48. Thereby, it can suppress that the connection member 34 remove | deviates from the recessed part 40. FIG. Thus, like this embodiment, the cover claw part 76 of the cover part 30 reinforces the connection part of the connection member 34 and the recessed part 40 (it regulates it hard to come off), and the cover part 30 is rear case. 22B can hold | maintain firmly and can maintain a waterproof space (waterproof space containing the battery mounting part 31 formed with the cover part 30 and the rear case 22B) more appropriately.

  Further, as shown in FIG. 16, when the cover portion 30 is attached to the rear case 22 </ b> B, the specific portion 63 can be seen from the notch 49, that is, between the rear case 22 </ b> B and the cover portion 30.

  Next, the operation of removing the cover 30 from the rear case 22B will be described with reference to FIGS. FIG. 17 is an explanatory diagram for explaining the removing operation of the cover portion, FIG. 18 is an explanatory diagram for explaining the removing operation of the cover portion, and FIG. 19 explains the removing operation of the cover portion. It is explanatory drawing for.

  In the state in which the cover 30 is attached to the rear case 22B as illustrated in FIG. 17, the portable electronic device 1 is configured such that when the specific portion 63 of the connecting member 34 is pressed from the notch 49 with a finger or the like, The connecting member 34 is deformed by the pressed force to have a shape like a connecting member 34a shown in FIG. The connecting member 34a slides and moves to the hinge part 4 side (in the direction of the arrow in FIGS. 17 and 18) by the force with which the specifying part 63 is pressed. When the state of the connecting member 34a is reached, the central claw portion 62 provided in the specifying portion 63 also moves in the arrow direction. In addition, as shown in FIG. 19, the connection member 34 is deform | transformed into the state of the connection member 34a when the specific part 63 is pushed in the arrow direction. At this time, the connecting member 34 is deformed with the fulcrum support portions 52 and 54 as fulcrums. As a result, the central claw portion 62 and the cover claw portion 76 are not overlapped with each other on the surface orthogonal to the thickness direction.

  Furthermore, the portable electronic device 1 is moved away from the rear case 22B by moving the end of the cover 30 away from the rear case 22B with a finger or the like while the nail is not caught. The

  Thus, the user can remove the cover part 30 from the rear case 22B simply by putting a finger into the cutout part 49 and then moving the cover part 30 in a direction away from the rear case 22B. Thus, the operation of placing a finger to remove the cover 30 can be an operation of removing the mechanism that connects the cover 30 and the rear case 22B. Thereby, the user can remove the cover part 30 by simple operation.

  Further, the specific portion 63 is deformed into the shape shown in the connecting member 34a when an external force in the direction indicated by the arrow in FIG. 19 is applied from the cutout portion 49, but is in a state in which no external force acts because of elastic deformation. Then, the state returns to the state of the connecting member 34 shown in FIG. That is, since the fulcrum support portions 52 and 54 are deformed as fulcrums, the restoring force is applied when the external force is not applied, and the shape returns to the shape when no external force is applied. As a result, when no external force is applied, the center claw portion 62 and the cover claw portion 76 overlap each other on the surface orthogonal to the thickness direction, and the cover portion 30 does not come off the rear case 22B.

  Thus, the portable electronic device 1 can prevent the cover part 30 from being detached from the rear case 22B by providing a mechanism including the connecting member 34. Specifically, the cover 30 can be prevented from being detached from the rear case 22B even if the portable electronic device 1 is accidentally dropped on the floor or the like. Further, since the movement in the thickness direction can be restricted by the claw portion, the distance between the cover portion 30 and the rear case 22B can be set to a certain distance or less. Thereby, the deviation | shift amount of each part can be grasped | ascertained and the sealing performance by the waterproof mechanism in the case of providing a waterproof function like this embodiment can be made higher. That is, by suppressing the shift, a more appropriate waterproof mechanism such as packing can be used, and the waterproofness can be increased.

  Further, the portable electronic device 1 has a shape in which the mechanism that connects the cover 30 and the rear case 22B (the mechanism that holds the cover 30 to the rear case 22B) is hardly visible from the outside. Thereby, the design property of the portable electronic device 1 can be made higher. Further, even when the mechanism connecting the cover part 30 and the rear case 22B is not visible, a waterproof structure is realized and a finger or the like is inserted into the cutout part 49 to remove the cover part 30. When the part 30 is separated from the rear case 22B, the cover part 30 can be removed from the rear case 22B. Moreover, since the state in which the cover part 30 is fitted in the rear case 22B is always locked, there is no need to arrange a lock lever or the like at a visible position, and an indication indicating the lock position (locked state). Display) is also unnecessary.

  In addition, since the connecting member 34 is also detachable, the connecting member 34 can be easily replaced. Moreover, it can be assembled easily at the time of assembly. Further, by using the connecting member 34 as a member that is elastically deformed, it is possible to reduce the possibility that the claw portion or the like is damaged when the connecting member 34 is deformed during attachment or detachment or when an impact is applied from the outside. That is, the durability of the device can be increased.

  Here, the connecting member 34 is preferably made of a material having lower rigidity than the rear case 22B (second housing 22) and the cover portion 30. Further, the connecting member 34 is preferably made of a material having a higher elastic modulus than the rear case 22B (second housing 22) and the cover portion 30. The material constituting the connecting member 34, the rear case 22B (second housing 22), and the cover portion 30 satisfies any of the above, so that the durability of each portion is increased and the rear case 22B (second housing) is increased. It is possible to make it difficult to remove the cover 30 from the body 22). For example, since the connecting member 34 is more easily deformed than other members, it is difficult for damage to occur even when the connecting member 34 is deformed. Moreover, it can also suppress that the nail | claw part which is contacting is damaged.

  In addition, as the connecting member 34, various resin materials and rubber materials can be used. For example, polyacetal can be used.

  The rear case 22B (second housing 22) and the cover 30 are preferably made of a material having high rigidity, specifically, a Young's modulus of 4000 or more. By manufacturing (constructing) the rear case 22B (second housing 22) and the cover portion 30 with a material having a high Young's modulus, a waterproof mechanism between the rear case 22B (second housing 22) and the cover portion 30 is used. It can be waterproofed more appropriately. That is, even if a force acts on the rear case 22B (second housing 22) and the cover portion 30 so that a gap is not generated by a waterproof mechanism such as packing, the wall surface can be prevented from being deformed and waterproofed. it can. In addition, as a material, the polycarbonate etc. which contained glass by a fixed ratio (for example, 10%), the nylon etc. which contained glass by a fixed ratio (for example, 45%) or more can be used. Even when a material having high rigidity is used for the rear case 22B (second housing 22) and the cover portion 30, the connecting member 34 is a deformable material, and the rear case 22B (second housing 22) and the cover portion 30 are used. The nails do not touch each other. For this reason, even if rigidity is made high, it can suppress that the mechanism which has connected both is damaged.

  In the above embodiment, only one of the outer claw portions faces the cover claw portion. However, the present invention is not limited to this. FIG. 20 is a cross-sectional view illustrating a schematic configuration of another embodiment of the connecting member. A connecting member 80 shown in FIG. 20 has the same configuration as the connecting member 34 except for the outer claw portion 82. Therefore, only the points different from the connecting member 34 will be described below. The outer claw portion 82 is provided at the same position as the outer claw portion 56 of the connecting member 34. The outer claw part (second claw part) 82 has a shape protruding in the thickness direction and extending in a direction away from the fulcrum support part 54 in the width direction. Further, the outer claw portion 82 faces the cover claw portion 76 on the surface opposite to the surface on which the protruding portion is provided. That is, the outer claw portion 82 has a shape obtained by inverting the outer claw portion 58 with the center in the width direction as the axis of symmetry. Note that the housing claw portion provided corresponding to the outer claw portion 82 also has a claw protruding direction opposite to the housing claw portion 46 of the above embodiment.

  In this way, by having a structure in which both of the outer claw portions face the cover claw portion 76, the outer claw portion and the cover claw portion 76 can be more difficult to come off when the cover portion 30 is attached, and the connecting member 80 and rear case 22B can be made harder to come off. Thereby, except when the external force acts on the specific part from the notch part, the cover part 30 can be more difficult to be detached from the rear case 22B. When the connecting member shown in FIG. 20 is used, it is difficult to mount the connecting member by sliding the connecting member in one direction with respect to the recess and engaging the claw portion as described above, but the connecting member has elasticity. Can be worn.

  In addition, since the rear case 22B (concave portion) can be made difficult to come off from the connecting member, the surface of the outer claw portion on which the protruding portion is not provided faces the cover claw portion in the vicinity as in the present embodiment. However, the outer claw portion does not necessarily have to face the cover claw portion.

  Further, as described above, by providing the outer claw portion and the housing claw portion, it is possible to make it difficult for the rear case 22B (concave portion) to come off from the connecting member, but the connecting member is fixed (held) to the rear case. ) The method is not limited to this. Moreover, in the said embodiment, since it was easy to assemble and an apparatus structure could be simplified, it was set as the structure which can attach or detach a connection member with respect to a recessed part, However, It is good also as a structure which fixes a connection member to a recessed part. Even when the connecting member is held in the recess with a structure other than the claw portion or when the connecting member is fixed to the recess, if an external force is applied from the notch portion 49, it is fixed in a deformed state, as described above. The cover portion can be held with respect to the housing while being easily detachable.

  The portable electronic device according to the above-described embodiment of the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope described in the claims.

  In the above description, the holding structure including the connecting member is used as a mechanism for fixing and holding the cover 30 covering the battery to the housing, but the present invention is not limited to this. The above-described holding structure can be used as a holding structure for various cover portions attached to the housing. Also, as described above, it is used as a holding structure for a cover part of a portable electronic device having a waterproof function that is required to be held more firmly (a cover part that is a part of a mechanism for realizing watertightness). However, it may be used as a cover portion of a portable electronic device that does not have a waterproof function.

  In the above description, the casing has been described as including two casings that can be closed, that is, the first casing and the second casing. However, the casing includes three or more casings. Alternatively, it may be composed of one.

  The casing of the portable electronic device 1 described above is not limited to a foldable structure. For example, the casing of the mobile electronic device 1 is in a state in which both casings are closed, in other words, from the overlapped state, one casing (first casing) and the other casing (second casing). Can be slidable with respect to each other, or can be rotated about one axis around the overlapping direction or via a two-axis hinge. What connected both the housing | casing may be used.

  As described above, the portable electronic device according to the present invention is suitable for application to various portable electronic devices including a cover part that can be attached to and detached from the housing.
