  An opening / closing lid 22 for housing the portable electronic device 100 in the main body 10 is provided on the side surface portion (planar member) 10c2 at the lower portion of the main body 10 (see FIG. 6C). Further, the left and right side surface portions (planar members) 10c3 of the main body 10 are provided with side surface opening portions 23 that expose the respective operation portions 130 and 140 that are physical keys that can be pressed on the stored portable electronic device 100. (See FIG. 7).

  As shown in FIG. 8, around the surface opening portion 11 of the main body 10, a side protrusion (protrusion) 25 that protrudes outward from the side surface 10 c that defines the storage space of the main body 10 is provided. In a state where the mobile electronic device 100 is housed in the main body 10, the side protrusion 25 protrudes outward from the mobile electronic device 100 with reference to the center of the display surface 107 of the display unit 102 of the mobile electronic device 100. The display surface 107 has a substantially quadrangular shape in plan view, and the side protrusions 25 are arranged along at least one side of the quadrilateral, but the second side facing the first side and the arbitrary first side of the quadrangle. It may be arranged along the side. In the present embodiment, the side protrusions 25 are arranged along the four sides of the rectangle.

  Further, in the closed state of the lid member 30, the peripheral portion of the lid member 30 is disposed on the side protrusion 25. In the present embodiment, the side protruding portion 25 is provided with a protruding region 26 that protrudes outward from at least the position where the lid member 30 is disposed in the direction along the surface portion 10a in the closed state (see FIG. 9).

  In this embodiment, although the back surface protrusion part 17 and the side surface protrusion part 25 were demonstrated separately, you may specify either the back surface protrusion part 17 or the side surface protrusion part 25 as a protrusion part simply.

  In the present embodiment, a plurality of openings are formed. The surface opening 11, the upper opening 12, the upper opening 20, the side opening 23, and the like, and each may be simply specified as the opening.

  The reinforcing member will be described in detail with reference to FIGS. The basic arrangement of the reinforcing members will be described with reference to FIGS.

  The outermost layer of the cover 1 is formed of a conductive member 40 having a conductivity made of leather such as cowhide, conductive resin or the like (see FIG. 13B, etc.). The conductive member 40 is composed of a portion formed of one layer and a portion formed of a laminate sandwiching the reinforcing member 50 in the middle. The reinforcing member 50 is also composed of a part formed from one layer and a part formed by lamination. The reinforcing member 50 is made of, for example, paper such as impregnated paper, a metal plate, or the like manufactured by stacking and compressing a plurality of thin papers and impregnating them with a predetermined impregnation liquid.

When the reinforcing member 50 is sandwiched in the conductive member 40, the conductive member 40 is divided into a first layer 41 having a first conductivity and a second layer 42 having a second conductivity. The reinforcing member 50 may be specified as a third layer having a third conductivity with a predetermined rigidity secured. Here, the first conductivity and the second conductivity may be the same. When the first layer 41 and the second layer 42 are made of the same material, the first conductivity and the second conductivity are the same, and the manufacture is facilitated. When the first layer 41 and the second layer 42 sandwich the reinforcing member 50, the cover 1 can obtain a predetermined rigidity.

  The use of the conductive member 40 having electrical conductivity for the outermost layer of the cover 1 is particularly for the purpose of explosion protection, and the reinforcing member 50 is also formed of paper having electrical conductivity, thereby ensuring higher explosion prevention. be able to. Further, if the conductive member 40 is leather (particularly cowhide), it has good conductivity and good touch and is suitable for the cover 1. In this case, either the first layer 41 or the second layer 42 may be formed of leather, and the other may be formed of another material. And the balance of reinforcement (rigidity) and lightness is made favorable by using the paper as a 3rd layer for the member 50 for reinforcement. When the paper has a third conductivity of a predetermined size, high explosion-proof performance can be ensured.

  An example of a specific arrangement of the reinforcing member 50 will be described (see FIG. 13B and the like).

  In this embodiment, the reinforcing member 50 uses four types of paper having different thicknesses. The first reinforcing member 50a is the thickest, for example, a thickness of 2.0 mm, and the second reinforcing member 50b is the next thickness, for example, a thickness of 1.25 mm. The third reinforcing member 50c is thinner, for example, a thickness of 1.0 mm, and the fourth reinforcing member 50d is the thinnest, for example, a thickness of 0.6 mm. Further, in some cases, the first to fourth reinforcing members 50a, 50b, 50c, and 50d are appropriately combined and used independently in order to increase the strength.

  10-12, the 1st reinforcement member 50a is shown by the oblique line with few inclinations, the 2nd reinforcement member 50b is shown by the oblique line which falls to the left side, the 3rd reinforcement member 50c is shown by the cross oblique line, The fourth reinforcing member 50d is indicated by a diagonal line descending to the right.

  The first reinforcing member 50a is disposed around the edge portion 33 provided along the longitudinal direction on one side surface of the front side 30a of the lid member 30 and the upper opening portion 20 provided in the upper side surface portion 10c1. Has been. Further, the second reinforcing member 50b includes the entire surface portion 10a of the main body 10 including the protruding region 26 of the side protrusion 25, the entire back surface 30b of the lid member 30, the back surface portion 10b of the main body 10, and the main body 10. It is arrange | positioned around the side surface opening part 23 provided in the right and left side surface part 10c3.

  The third reinforcing member 50 c is disposed on the presser portion 21 provided on the side surface portion 10 c 1 at the top of the main body 10. In addition, the fourth reinforcing member 50 d is disposed over substantially the entire area of the lid member 30.

  By devising the structure of each part and arranging the reinforcing members 50 having different thicknesses, the strength of the entire cover 1 is increased and the portable electronic device 100 that is housed is protected from impact and the like. An example of a specific embodiment will be further described with reference to FIG.

As shown in FIG. 13B, when the portable electronic device 100 is housed inside the main body 10 and the lid member 30 is placed on the surface portion 10 a of the main body 10 to be in the closed state, the portable electronic device 100 is placed on the back side 30 b of the lid member 30. The second reinforcing member 50b is disposed on the main body 10 side. The fourth reinforcing member 50d disposed on the front side 30a of the lid member 30 is disposed on the front side of the cover 1 in the closed state. That is, the third layer 51 of the reinforcing member 50 sandwiched between the first layer 41 and the second layer 42 of the conductive member 40 is the fourth reinforcing member 50d and the second reinforcing member 50d. It is comprised with the 5th layer which is the member 50b. In this way, by constituting at least two layers (the fourth reinforcing member 50d and the second reinforcing member 50b), it becomes difficult for the impact to be transmitted between the layers, so that the impact can be effectively absorbed.
The arrangement is such that the thin fourth reinforcing member 50d (fourth layer) is on the top and the thick second reinforcing member 50b (fifth layer) is on the bottom. That is, the thick second reinforcing member 50b (fifth layer) is disposed at a position closer to the display unit 102 of the portable electronic device 100 than the thin fourth reinforcing member 50d (fourth layer). According to this configuration, the impact applied from the front side of the lid member 30 is greatly absorbed by the thin layer, and then the impact is dispersed by the thick layer that is strong and difficult to bend. The impact can be effectively absorbed without increasing the thickness (including the fourth reinforcing member 50d and the second reinforcing member 50b), and the display portion 102 partially formed of glass or the like is protected. It becomes possible.

  By projecting outward from the side surface portion 10c that defines the storage space of the main body 10 and providing a thick and strong side surface projection portion 25, when the cover 1 housing the portable electronic device 100 falls, the projection portion The impact received by the projecting portion 25 is transmitted to the second reinforcing member 50b disposed along the display surface 107, and is transmitted from the entire main body 10 to the portable electronic device 100. It is possible to reduce the impact on 100. Further, since the outermost layer of the cover 1 is the conductive member 40, it has an explosion-proof structure even if it is dropped on a metal floor or the like, and the portable electronic device 100 can be used safely without causing an electric spark or the like. It is said.

  As shown in FIG. 14C, the second reinforcing member 50b is arranged at the center of the protruding region 26 so as to sandwich the first reinforcing member 50a and the fourth reinforcing member 50d from both sides. The laminated structure is four layers thicker than other parts.

  The protruding region 26 of the side protruding portion 25 protrudes outward from the position where the lid member 30 is disposed in the closed state in which the surface opening 11 is covered by the lid member 30 while also protecting the surface opening 11 of the main body 10. Thus, the impact resistance strength of the cover 1 is increased. Further, the projecting region 26 is formed of a four-layer laminated structure of the reinforcing member 50 and is thicker than the other regions of the side projecting portion 25, so that the impact resistance is further enhanced.

  In the present embodiment, an example in which the side protrusions 25 are protruded from all the side parts 10c of the main body 10 in order to further improve the impact property has been described, but the location and number of protrusions are not limited, and the side protrusions 25 May protrude from at least one side surface portion 10c. Of course, the side protrusions 25 may be protruded from the two opposite side faces 10c.

  As shown in FIG. 15 (c), the operation portion covering portion 13 covering the pressing operation portion 103 of the portable electronic device 100 provided on the surface portion 10a of the main body 10 includes an operation portion region 13a, a surrounding region 13b, and an operation portion. And an adjacent region 13c adjacent to the outside on the basis of the partial region 13a. Two second reinforcing members 50b that are third layers sandwiched between the first layer 41 and the second layer 42 are disposed in the operation portion region 13a. The third layer is rigid and stronger than the first layer and the second layer, facilitating the operation of the pressing operation unit 103.

  In order to make the pressing operation of the pressing operation unit 103 easier, the second reinforcing member 50b that is the third layer is not arranged in the surrounding region 13b. Further, the third layer is disposed in the adjacent region 13c, and this third layer is composed of one second reinforcing member 50b. That is, in order to more reliably perform the pressing operation of the pressing operation unit 103, the thickness of the third layer of the operation unit region 13a (the thickness of the two second reinforcing members 50b) is set to the thickness of the third layer of the adjacent region 13c. It is thicker than (one second reinforcing member 50b).

  As shown in FIG. 16 (b), the upper side opening 20 that enables use of the transparent member 110 and the optical interface unit 111 provided on the upper side surface 100 c of the portable electronic device 100 is provided in the upper side surface portion 10 c 1 of the main body 10. It has been. A thick part 20 a having a predetermined thickness is provided at least at a part of the periphery of the upper opening 20. At least a part of the thick portion 20 a is disposed so as to overlap the casing 101 around the transparent member 110 of the portable electronic device 100.

  The thick part 20a includes a thick part 20a1 and a thick part 20a2 arranged on both sides of the upper opening 20, and is formed thicker than the thickness of the upper side part 10c1 other than the thick part 20a.

  The thick portion 20a1 has a three-layer structure including a first layer 41 and a second layer 42 of the conductive member 40, and a first reinforcing member 50a sandwiched between the first layer 41 and the second layer 42. ing. That is, since the upper side surface portion 10c1 is based on the single layer structure of the conductive member 40, the thick portion 20a1 having a three-layer structure is thicker than the upper side surface portion 10c1. The stacking direction of the three-layer structure is a vertical direction away from the upper side surface portion 10c1 and the upper side surface 100c of the portable electronic device 100. On the other hand, the thick portion 20a2 is the above-described protruding region 26 (see FIGS. 14B and 14C), and the stacking direction of the thick portion 20a2 is the upper side surface portion 10c1 and the upper side surface of the portable electronic device 100. It is arranged along 100c. Also, as shown in FIGS. 16A and 16B, the thick portion 20a2 is in direct contact with the casing 101 around the transparent member 110 of the portable electronic device 100 without passing through the upper side surface portion 10c1.

  By providing the thick portion 20a around the upper opening 20, the transparent member 110 and the optical interface portion 111 are explosion-proof, and in particular, the transparent member 110 having a lower strength than the housing 101 is protected from impact or the like. That is, it is possible to prevent the transparent member 110 made of resin or the like from breaking and entering the optical interface unit 111 with combustible gas or the like. It is considered that the conductor of the electric circuit is exposed to the atmosphere due to an impact or the like in the optical interbase part. However, since the transparent member 110 is not cracked, the flammable gas is prevented from coming into contact with the conductor and energized. It is possible to suppress the ignition of the combustible gas by the conductive wire. Further, since the thick portion 20a is in contact with the casing 101 directly or via the upper side surface portion 10c1, the impact received by the thick portion 20a is not directly applied to the transparent member 110. .

  In addition, although the upper side opening part 20 is opened so that it may not overlap with the transparent member 110, you may overlap partially.

  As shown in FIGS. 16A and 16C, a pusher portion 21 that covers the push-type operation portion 112 of the portable electronic device 100 is provided adjacent to the upper opening 20. In particular, the pusher portion 21 is disposed between the upper opening 20 and the thick portion 20a1. In the pusher portion 21, the third reinforcing member 50 c is sandwiched between the first layer 41 and the second layer 42. Here, the total thickness of the thick portion 20a is defined as the first thickness, and the total thickness of the presser portion 21 is defined as the second thickness. As the relationship between the first thickness and the second thickness, one of the same, the first thickness is larger than the second thickness, and the first thickness is smaller than the second thickness can be selected. . If it is the same, manufacturing is easy, and if the first thickness is greater than the second thickness, the protection of the operation unit 112 is enhanced. If the first thickness is less than the second thickness, the operation unit 112 is It becomes easy to operate.

  As shown in FIGS. 12B, 12C, etc., the left and right side surface portions 10c3 of the main body 10 expose the respective operation portions 130 and 140 that are physical keys that can be pressed on the stored portable electronic device 100. Since the opening portion 23 is provided and has the same configuration, the left side surface portion 10c3 and the operation portion 130 will be described with reference to FIG.

A thick portion 23 a is provided around the side opening 23 in the same manner as the upper opening 20. In the first thick portion (thick portion) 23a1 arranged along the longitudinal direction of the left side surface portion 10c3, the second reinforcing member 50b is replaced with the conductive member 40 (the first layer 41 and the second layer 42). It is a three-layer structure sandwiched. The first thick part 23a1 is larger than the thickness of the side part 10c. On the other hand, the second thick portion (thick portion) 23a2 arranged along the short side direction of the left side surface portion 10c3 is composed of the conductive member 40. The first thickness of the first thick part 23a1 is formed to be larger than the second thickness of the second thick part 23a2, and mitigates external impacts and the like. By providing a conductive member 40 having conductivity around the operation units 130 and 140, the operation units 130 and 140 are explosion-proof. That is, even when a charged human body (for example, a finger) is likely to come into contact with the operation units 130, 140, etc., the charged electric charge comes into contact with the surrounding conductive member 40, and the charged charge is applied to the conductive member 40 having a predetermined conductivity. Since it comes into contact with the operation units 130 and 140 after escaping, the operation units 130 and 140 can be prevented from being charged. Thereby, the ignition to the gas etc. by the operation parts 130 and 140 being charged can be suppressed. The second thick part 23a2 is easily touched by a finger of a user who is trying to access the side opening 23, but is formed thinner than the first thick part 23a1, and prevents the access. It is hard to become.

  In the present embodiment, the thick portion 20a and the thick portion 23a are configured by the laminated structure of the conductive member 40 and the reinforcing member 50. However, the thick portions 20a and 23a are the first layer 41 and the first layer 41 of the conductive member 40. You may comprise with two layers 42.

I explained that. The rear surface protrusions 17 each have a predetermined width with respect to the short side direction of the rear surface part 10b, and are arranged with a predetermined width shift.

  The protrusion in the separating direction is for giving elasticity, and the strap 15 is separated in a curved shape from the back surface portion 10b of the main body 10 so that the user can easily hold it, and the cushion member 16 is partially rounded. It is comprised from the strip-shaped member.

  The rear surface protrusion 17 is divided into two independent members, the strap 15 and the cushion member 16, and has elasticity in a direction away from the portable electronic device 100 while enabling different roles. Therefore, even when a foreign object falls on the cover 1 housing the portable electronic device 100 or when the cover 1 falls, the impact can be effectively absorbed. In consideration of user convenience, the strap 15 is disposed on the lower side, and the cushion member 16 provided on the upper side of the strap 15 ensures shock absorption.

  As shown in FIG. 18B, when the portable electronic device 100 is housed in the main body 10, the cover 1 naturally tilts to the left or right due to the weight of the portable electronic device 100, and foreign matter from the outside to the portable electronic device 100 is removed. Reduces shocks caused by falling. That is, with the back surface protruding portion 17 as a reference, the back surface portion 10 b of the main body 10 is supported by a part on one end side or the other end side of the main body 10 and the back surface of the back surface protruding portion 17 and is allowed to stand. Is done. In FIG. 18B, the cushion member 16 is not drawn, but this is simply hidden behind, and the main body 10 in FIG. 18B also includes the cushion member 16.

  As described above, by devising the structure of each part of the cover 1 and arranging the reinforcing members 50 having different thicknesses, the strength of the cover 1 as a whole is increased and the portable electronic device 100 stored therein is protected from impacts and the like. ing. In particular, the portable electronic device 100 used at a construction site, a work site, a safety processing site, an inspection site in a factory, and the like is heavier than a normal mobile phone and has a large drop impact force. The explosion-proof and impact resistance of the portable electronic device 100 is improved by the combination of the lamination of the conductive member 40 and the reinforcing member 50. Further, the thickness of the thick portions 20a and 23a is changed, and an explosion-proof measure is taken in the operation portions 112, 130, and 140 to improve operability.

  Although the cover 1 and the portable electronic device 100 have been described separately above, the portable electronic device 100 may include the cover 1.
