Lid member 30 has front side 30a and rear side 30b, and is described below on the assumption that a surface facing and coming into contact with front surface portion 10a of body 10 in the closed state is rear side 30b. Since FIG. 4 is a front view, description of front surface portion 10a of body 10, front side 30a of lid member 30, and the like is provided, but the disclosure is not limited to the terms of the front surface, the rear surface, and the like.

Lid member 30, and front surface portion 10a, rear surface portion 10b, and side surface portions 10c of body 10 (including upper side surface portion lOcl, lower side surface portion 10c2, and right and left side surface portions 10c3 described below) form respectively planar shapes thereby capable of being specified as the planar members. For distinguishing, for example, lid member 30 may be specified as a first planar member, front surface portion 10a may be specified as a second planar member, and rear surface portion 10b may be specified as a third planar member. Of course, lid member 30 may be specified as the third planar member, front surface portion 10a may be specified as the first planar member, and rear surface portion 10b may be specified as the second planar member. Lid member 30 may be specified as the second planar member, front surface portion 10a may be specified as the third planar member, and rear surface portion 10b may be specified as the first planar member.

In the closed state in which portable electronic apparatus 100 is stored in cover 1 and lid member 30 is mounted on front surface portion 10a of body 10, front surface portion 10a of cover 1 is present between lid member 30 and portable electronic apparatus 100, and is disposed along front surface 100a of portable electronic apparatus 100. Rear surface portion 10b of body 10 is disposed along rear surface 100b of portable electronic apparatus 100.

As illustrated in FIG. 5, strap 15 that is capable of being gripped by a user and cushion member 16 protruding in a state of extending in the longitudinal direction of body 10 are provided in the vicinity of the center of body 10 in an axial direction in rear surface portion 10b of body 10. Strap 15 is fixed to body 10 on the lower side of body 10 in the longitudinal direction, cushion member 16 is fixed to body 10 on the upper side of body 10 in the longitudinal direction. Strap 15 and cushion member 16 are respectively divided into independent members and form rear surface protrusions (protrusions) 17. If the user grips strap 15, strap 15 is positioned below cushion member 16.

Since rear surface protrusions 17 are divided into two independent members, strap 15 may be specified as a first member and cushion member 16 may be specified as a second member. Strap 15 may be specified as the second member and cushion member 16 may be specified as the first member.

Rear surface protrusion 17 is disposed along midline X-X of portable electronic apparatus 100 in a state in which portable electronic apparatus 100 is stored in body 10 and protrudes in a direction away relative to portable electronic apparatus 100 (protrusion state refers to FIGS. 7A and 7C). Rear surface protrusion 17 is disposed along the longitudinal direction to include midpoint O in the longitudinal direction of rear surface 100b of portable electronic apparatus 100 and, for example, may be disposed over at least 90% or more in the longitudinal direction. Otherwise, rear surface protrusion 17 may be disposed over at least 80% or more, 70% or more, or 60% or more in the longitudinal direction. Simultaneously, rear surface protrusion 17 includes a predetermined width in a lateral direction of rear surface 100b and, as illustrated in FIG. 5, for example, may include a width of 40% or less in the lateral direction. Otherwise, rear surface protrusion 17 may include the width of 30% or less, 20% or less, 10% or less, or 5% or less in the lateral direction. It is possible to effectively absorb impact to cover 1 as described below while securing ease of use with such a configuration.

Midpoint O may be also considered as center point O of rear surface 100b. Rear surface protrusion 17 may be disposed along a substantially straight line (this can be regarded as the midline) passing through center point O and, for example, rear surface protrusion 17 may be disposed along a diagonal line (passing through center point O) of rear surface 100b that is a substantially rectangular shape in a plan view.

As illustrated in FIG. 6A, upper opening portion 20 corresponding to optical interface unit 111 of portable electronic apparatus 100 storedin body 10 and exposing optical interface unit 111, and pusher 21 covering push type operator 112 are provided in upper side surface portion (planar member) lOcl of body 10. Upper opening portion 20 is opened to expose entire transparent member 110 disposed corresponding to optical interface unit 111. Upper opening portion 20 may expose at least a part of transparent member 110 in addition to the exposing of entire transparent member 110.

Opening and closing lid 22 for storing portable electronic apparatus 100 in body 10 is provided in lower side surface portion (planar member) 10c2 of body 10 (see FIG. 6C). Side opening portions 23 exposing each of operators 130 and 140 that are the physical keys capable of being pushed, of stored portable electronic apparatus 100 are provided in right and left side surface portions (planar members) 10c3 of body 10 (see FIGS. 7A to 7C).

As illustrated in FIGS. 8A and 8B, side surface protrusion (protrusion) 25 protruding from side surface portions 10c defining the storing space of body 10 to the outside is provided around front surface opening portion 11 of body 10. In a state in which portable electronic apparatus 100 is stored in body 10, side surface protrusion 25 protrudes to the outside from portable electronic apparatus 100 relative to the center in display surface 107 of display 102 of portable electronic apparatus 100. Display surface 107 is a substantially quadrangle in a plan view and side surface protrusion 25 is disposed along at least one side of the quadrangle, but may be disposed along an arbitrary first side of the quadrangle and a second side facing the first side. In the cover illustrated in FIGS. 8A and 8B, side surface protrusion 25 is disposed along four sides of the quadrangle.

In the closed state of lid member 30, a peripheral portion of lid member 30 is disposed on side surface protrusion 25. In the cover illustrated in FIG. 9, at least protrusion region 26 protruding from an arrangement position of lid member 30 to the outside in a direction along front surface portion 10a during the closed state is provided in side surface protrusion 25.

Rear surface protrusion 17 and side surface protrusion 25 are described separately, but both rear surface protrusion 17 and side surface protrusion 25 may be simply specified as the protrusion portion. A plurality of opening portions are formed in the cover 1. The opening portions are front surface opening portion 11, upper opening portion 12, upper opening portion 20, side opening portions 23, and the like, and may be respectively specified as the opening portions.

Reinforcing members will be described in detail with reference to FIG. 10 to FIGS. 17A to 17C. A basic arrangement of the reinforcing members will be described with reference to FIG. 10 to FIGS. 13A and 13B.

The outermost layer of cover 1 is formed of conductive member 40 having a conductivity formed of leather such as calfskin, conductive resin, and the like (see FIG. 13B). Conductive member 40 is configured of a portion that is formed of one layer and a portion that is formed by laminating reinforcing member 50 to sandwich reinforcing member 50 in an intermediate portion. Reinforcing member 50 is configured of a portion that is formed of one layer and a portion that is formed by being laminated. Reinforcing member 50 is formed of, for example, paper such as impregnated paper manufactured by compressing a plurality of superimposed thin paper and impregnating paper into predetermined impregnation liquid, a metal plate, and the like.

In a case in which reinforcing member 50 is sandwiched within conductive member 40, conductive member 40 is specified by being divided into first layer 41 having a first conductivity and second layer 42 having a second conductivity. Reinforcing member 50 may be specified as a third layer having a third conductivity in which predetermined rigidity is secured. The first conductivity and the second conductivity may be equal to each other. In a case in which first layer 41 and second layer 42 are formed of the same material, the first conductivity and the second conductivity are equal to each other and manufacturing thereof is facilitated. First layer 41 and second layer 42 sandwich reinforcing member 50 and thereby cover 1 can obtain predetermined rigidity.

For the explosion-proof measures, particularly, conductive member 40 having the conductivity is used in the outermost layer of cover 1, reinforcing member 50 is also formed of paper and the like having a conductivity, and thereby it is possible to secure higher explosion-proof. If conductive member 40 is formed of leather (particularly, calfskin), the conductivity is good and feeling is also good, and thus leather is suitable for cover 1. In this case, one of first layer 41 and second layer 42 is formed of leather and the other may be formed of another material. Paper is used for reinforcing member 50 as the third layer and thereby balance of reinforcement (rigidity) and lightness is improved. In a case in which the paper has a third conductivity of a predetermined size, it is possible to secure high explosion-proof.

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

Four types of paper having different thicknesses are used for reinforcing member 50. First reinforcing member 50a is the thickest and has, for example, a thickness of 2.0 mm, and second reinforcing member 50b is the second thickest and has, for example, a thickness of 1.25 mm. Third reinforcing member 50c is thinner and has, for example, a thickness of 1.0 mm, and fourth reinforcing member 50d is the thinnest and has, for example, a thickness of 0.6 mm. In order to improve the strength by appropriately combining each of first to fourth reinforcing members 50a, 50b, 50c, and 50d, first to fourth reinforcing members 50a, 50b, 50c, and 50d may be used by being independently laminated.

In FIG. 10 to FIGS. 12A to 12C, first reinforcing member 50a is illustrated by oblique lines having low slopes, second reinforcing member 50b is illustrated by oblique lines falling to the left side, third reinforcing member 50c is illustrated by cross oblique lines, and fourth reinforcing member 50d is illustrated by oblique lines falling to the right side.

First reinforcing member 50a is disposed in edge portion 33 provided along one side surface of front side 30a of lid member 30 in the longitudinal direction and a periphery of upper opening portion 20 provided in upper side surface portion 10c 1. Second reinforcing member 50b is disposed in entire front surface portion 10a of body 10 including protrusion region 26 of side surface protrusion 25, entire rear side 30b of lid member 30, rear surface portion 10b of body 10, and a periphery of side opening portion 23 provided in right and left side surface portions 10c3 of body 10.

Third reinforcing member 50c is disposed in pusher 21 provided in upper side surface portion lOcl of body 10. Fourth reinforcing member 50d is disposed in substantially entire lid member 30.

The strength of entire cover 1 is increased and stored portable electronic apparatus 100 is prevented from the impact and the like by devising the structure of each portion and disposing reinforcing members 50 having different thicknesses. A specific example will be further described with reference to FIGS. 13A and 13B to FIGS. 17A to 17C.

As illustrated in FIG. 13B, in the closed state by storing portable electronic apparatus 100 in the inside of body 10 and disposing lid member 30 in front surface portion 10a of body 10, second reinforcing member 50b disposed in rear side 30b of lid member 30 is disposed on body 10 side. Fourth reinforcing member 50d disposed in front side 30a of lid member 30 is disposed on the front side in cover 1 of the closed state. That is, third layer 51 of reinforcing member 50 sandwiched by first layer 41 and second layer 42 of conductive member 40 is configured of a fourth layer that is fourth reinforcing member 50d and a fifth layer that is second reinforcing member 50b. As described above, the impact is unlikely to be transmitted between layers and it is possible to effectively absorb the impact by configuring reinforcing member 50 with at least two layers (fourth reinforcing member 50d and second reinforcing member 50b).

The arrangement is in a state in which fourth thin reinforcing member 50d (fourth layer) is disposed on the upper side and second thick reinforcing member 50b (fifth layer) is disposed on the lower side. That is, second thick reinforcing member 50b (fifth layer) is disposed in a position closer to display 102 of portable electronic apparatus 100 than fourth thin reinforcing member 50d (fourth layer). According to the configuration, the impact applied from the front side of lid member 30 is greatly absorbed by the thin layer and then the impact is dispersed by the thick layer of which the rigidity is strong and which is hard to be bent. Therefore, it is possible to effectively absorb the impact and to protect display 102 a part of which is configured of glass and the like, without increasing the entire thickness (including fourth reinforcing member 50d and second reinforcing member 50b).

When cover 1 storing portable electronic apparatus 100 is dropped, protrusion 25 is hit first, the impact received by protrusion 25 is transmitted to second reinforcing member 50b disposed along display surface 107, and the impact is transmitted from entire body 10 to portable electronic apparatus 100 by providing side surface protrusion 25 protruding on the outside from side surface portion 10c defining the storing space of body 10 and having the thick thickness and the strength. Therefore, it is possible to alleviate the impact with respect to portable electronic apparatus 100. Since the outermost layer of cover 1 is conductive member 40, for example, cover 1 has the explosion-proof structure even if cover 1 is dropped on a metal floor and the like, and it is possible to safely use portable electronic apparatus 100 without causing an electrical spark and the like.

As illustrated in FIG. 14C, second reinforcing members 50b are disposed so as to interpose first reinforcing member 50a and fourth reinforcing member 50d from both sides and four-layered laminated structure that is thicker than other portions is provided in the center portion of protrusion region 26.

Protrusion region 26 of side surface protrusion 25 protrudes from the arrangement position of lid member 30 to the outside in the closed state in which front surface opening portion 11 is covered by lid member 30 also serving for the protection of front surface opening portion 11 of body 10 and thereby impact resistance strength of cover 1 is increased. Since protrusion region 26 is formed of the four-layered laminated structure of reinforcing member 50 and has the thickness thicker than other regions of side surface protrusion 25, the impact resistance is further increased.

The cover illustrated in FIGS. 8A and 8B is an example in which side surface protrusion 25 protrudes from side surface portion 10c in entire body 10 to further increase impact property is described, but locations and the number of the protrusions are not limited, and side surface protrusion 25 may protrude from at least one side surface portion 10c. Of course, side surface protrusions 25 may protrude from two side surface portions 10c facing each other.

As illustrated in FIG. 15C, operator covering portion 13 covering pushing operator 103 of portable electronic apparatus 100 provided in front surface portion 10a of body 10 has operator region 13a, peripheral region 13b, and adjacent region 13c adjacent to the outside relative to operator region 13a. Two second reinforcing members 50b that are the third layer sandwiched between first layer 41 and second layer 42 are disposed in operator region 13a. The third layer is rigid, has strength greater than those of the first layer and the second layer, and facilitates the operation of pushing operator 103.

In order to facilitate the pushing operation of pushing operator 103, second reinforcing member 50b that is the third layer is not disposed in peripheral region 13b. The third layer is disposed in adjacent region 13c and the third layer is configured of one second reinforcing member 50b. That is, in order to reliably perform the pushing operation of pushing operator 103, a thickness (thickness of two second reinforcing members 50b) of the third layer of operator region 13a is thicker than a thickness (one second reinforcing member 50b) of the third layer of adjacent region 13c.

As illustrated in FIG. 16B, upper opening portion 20 capable of using transparent member 110 and optical interface unit 111 provided in upper side surface 100c of portable electronic apparatus 100 is provided in upper side surface portion lOcl of body 10. Thick portion 20a including a predetermined thickness is provided in at least a part of a periphery of upper opening portion 20. At least a part of thick portion 20a is disposed to overlap with housing 101 of the periphery of transparent member 110 of portable electronic apparatus 100.

Thick portion 20a includes thick portion 20al and thick portion 20a2 disposed on both sides of upper opening portion 20, and is formed to be thicker than upper side surface portion 10c 1 other than thick portion 20a.

Thick portion 20al has a three-layered structure of first layer 41 and second layer 42 of conductive member 40, and first reinforcing member 50a sandwiched between first layer 41 and second layer 42. That is, since upper side surface portion 10c 1 has basically a one-layered structure of conductive member 40, thick portion 20al having the three-layered structure is thicker than upper side surface portion 10c 1. A laminating direction of the three-layered structure is a vertical direction away from upper side surface portion lOcl and upper side surface 100c of portable electronic apparatus 100. On the other hand, thick portion 20a2 is protrusion region 26 (see FIGS. 14B and 14C) described above and a laminating direction of thick portion 20a2 is disposed along upper side surface portion 10c 1 and upper side surface 100c of portable electronic apparatus 100. As illustrated in FIGS. 16A and 16B, thick portion 20a2 comes into contact with housing 101 of the periphery of transparent member 110 of portable electronic apparatus 100 without upper side surface portion 10c 1.

Transparent member 110 and optical interface unit 111 are explosion-proofed and particularly, transparent member 110 of which the strength is weaker than that of housing 101 is protected from the impact and the like by providing thick portion 20a in the periphery of upper opening portion 20. That is, it is possible to prevent flammable gas from entering optical interface unit 111 due to brokenness of transparent member 110 made of resin and the like. It is conceivable that conductors of an electric circuit are exposed to the atmosphere by the impact and the like in the optical interface unit. Transparent member 110 is not broken and thereby it is possible to suppress the flammable gas that comes into contact with the conductors and to suppress ignition of flammable gas due to energized conductors. Since thick portion 20a has a structure coming into contact with housing 101 directly or via upper side surface portion lOcl, the impact received by thick portion 20a is not directly applied to transparent member 110.

Upper opening portion 20 is opened so as not to overlap with transparent member 110, but may partially overlap with transparent member 110.

As illustrated in FIGS. 16A and 16C, pusher 21 covering push type operator 112 of portable electronic apparatus 100 is provided adjacent to upper opening portion 20. Particularly, pusher 21 is disposed between upper opening portion 20 and thick portion 20a 1. Third reinforcing member 50c is sandwiched between first layer 41 and second layer 42 in pusher 21. The entire thickness of thick portion 20a is defined as a first thickness and the entire thickness of pusher 21 is defined as a second thickness. As a relationship between the first thickness and the second thickness, it is possible to select one of cases in which the first thickness and the second thickness are equal to each other, the first thickness is thicker than the second thickness, and the first thickness is thinner than the second thickness. If the first thickness and the second thickness are equal to each other, manufacturing is facilitated, if the first thickness is thicker than the second thickness, protection strength of operator 112 is enhanced, and if the first thickness is thinner than the second thickness, operator 112 is easily operated.

As illustrated in FIGS. 12B, 12C, and the like, side opening portions 23 exposing operators 130 and 140 respectively that are the physical keys capable of being pushed, of stored portable electronic apparatus 100 are provided in right and left side surface portions 10c3 of body 10 and have the same configuration. Thus, left side surface portion 10c3 and operator 130 will be describedin FIGS. 17Ato 17C.

Similar to upper opening portion 20, thick portion 23a is provided in the periphery of side opening portion 23. First thick portion (thick portion) 23al disposed along the longitudinal direction of left side surface portion 10c3 has a threeTayered structure in which second reinforcing member 50b is sandwiched between conductive members 40 (first layer 41 and second layer 42). First thick portion 23a 1 is thicker than the thickness of side surface portion 10c. On the other hand, second thick portion (thick portion) 23a2 disposed along the lateral direction of left side surface portion 10c3 is configured of conductive member 40. A first thickness of first thick portion 23al is formed to be greater than a second thickness of second thick portion 23a2 and alleviates the impact from the outside. Operators 130 and 140 are explosion-proofed by providing conductive member 40 having a conductivity in the periphery of operators 130 and 140. That is, even in a case in which a charged human body (for example: finger) tries to come into contact with operators 130 and 140, and the like, the human body comes into contact with conductive member 40 of the periphery so that the charged electric charge is escaped to conductive member 40 having a predetermined conductivity and then the human body comes into contact with operators 130 and 140. Therefore, it is possible to suppress that operators 130 and 140 are charged. Thus, it is possible to suppress ignition of gas and the like due to charging of operators 130 and 140. Second thick portion 23a2 is likely to come into contact with the finger of the user trying to access side opening portion 23, but is formed to be thinner than first thick portion 23al, and thus is unlikely to interfere with the access.

In the embodiment, thick portion 20a and thick portion 23a are configured by a laminated structure of conductive member 40 and reinforcing member 50, but thick portions 20a and 23a may be configured by first layer 41 and second layer 42 of conductive member 40.

As illustrated in FIGS. 18A and 18B, rear surface protrusion 17 having strap 15 and cushion member 16 is provided in rear surface portion 10b of body 10. In FIG. 5, rear surface protrusion 17 is described to be disposed along midline X-X of portable electronic apparatus 100 and to protrude in the direction away relative to portable electronic apparatus 100 in a state in which portable electronic apparatus 100 is stored in body 10. Rear surface protrusions 17 include respectively predetermined widths in the lateral direction of rear surface portion 10b and are disposed to be displaced by a predetermined width.

The protrusion in the away direction is for providing elasticity, strap 15 is separated from rear surface portion 10b of body 10 in a curved shape so that the user easily grips strap 15, and cushion member 16 is configured of a belt-like member that is partially rounded.

Rear surface protrusion 17 is divided into strap 15 and cushion member 16 that are two independent members and has elasticity in the direction away relative to portable electronic apparatus 100 while enabling different roles respectively. Therefore, even in a case in which foreign matters are dropped on cover 1 storing portable electronic apparatus 100 or cover 1 is dropped, it is possible to effectively absorb the impact. Strap 15 is disposed on the lower side by considering ease of use of the user and impact absorption is secured by cushion member 16 disposed on the upper side from strap 15.

As illustrated in FIG. 18B, if portable electronic apparatus 100 is stored in body 10, cover 1 is naturally inclined to the left or right side due to the weight of portable electronic apparatus 100 and the impact due to dropping of the foreign matters from the outside to portable electronic apparatus 100 is alleviated. That is, portable electronic apparatus 100 is supported and stationary disposed on a part of rear surface portion 10b of body 10 on one end side or the other end side relative to rear surface protrusion 17 and the rear surface of rear surface protrusion 17, and the impact is alleviated by an elastic force of rear surface protrusion 17. In FIG. 18B, cushion member 16 is not illustrated, but this is simply hidden in the shadow and body 10 also includes cushion member 16 in FIG. 18B.

As described above, the strength of entire cover 1 is increased and stored portable electronic apparatus 100 is protected from the impact and the like by devising the structure of each portion of cover 1 and disposing reinforcing members 50 having different thicknesses. Particularly, portable electronic apparatus 100 used in a construction site, a work site, a safety processing site, an inspection site in a factory, and the like has a weight heavier than that of a normal mobile phone and a dropping impact force is also great. The explosion-proof and the impact resistance of portable electronic apparatus 100 are improved by a combination of the lamination of conductive member 40 and reinforcing member 50. The thicknesses of thick portions 20a and 23a are changed, the explosion-proof measures are performed in operators 112, 130, and 140, and the operability is improved.

Cover 1 and portable electronic apparatus 100 are described above separately, but portable electronic apparatus 100 may include cover 1.

The disclosure is not limited to the examples described above and modifications, improvements, and the like can be made appropriately. Moreover, a material, a shape, dimensions, numerical values, a form, the number, an arrangement position, and the like of each configuration element in the examples described above are arbitrarily and are not limited as long as it can attain the disclosure.

Explosion-proof required in a chemical plant site and the like, and the impact resistance required in a construction site, a work site, a safety processing site, and the like are satisfied by using the cover and the portable electronic apparatus of the disclosure, and it is possible to appropriately use the cover and the portable electronic apparatus of the disclosure.
