As illustrated in FIGS. 8A and 8B, the lateral surface projection (projection) projecting from the lateral surface portions 10c defining the storage space of the body 10 outside, is provided around the opening portion of front surface 11 of the body 10. In a state in which the portable electronic device 100 is stored in the body 10, the lateral surface projection 25 projects outside of the portable electronic device 100 relative to the center in the display surface 107 of the screen 102 of the portable electronic device 100. The display surface 107 is substantially quadrilateral in a plan view and the lateral surface projection 25 is arranged along at least one side of the quadrilateral, but may be arranged along an arbitrary first side of the quadrilateral and a second side facing the first side. In the shell illustrated in Figures 8A and 8B, the lateral surface projection 25 is arranged along four sides of the quadrilateral.

In the closed state of the cover element 30, a peripheral part of the cover element 30 is arranged on the lateral surface projection 25. In the shell illustrated in FIG. 9, at least the projection region 26 forming a projection from an arrangement position of the cover element 30 on the outside in a direction along the front surface part 10a during the closed state is provided in the lateral surface projection 25.

The rear surface projection 17 and the side surface projection 25 are described separately, but both the rear surface projection 17 and the side surface projection 25 can be simply specified as a projection part.

A plurality of opening parts are formed in the shell 1. The opening parts are the front surface opening part 11, the upper opening part 12, the upper opening part 20, the parts of side openings 23 and the like and may be respectively specified as parts of openings.

The reinforcing elements will be described in detail with reference to Figure 10 and Figures 17A to 17C. A basic arrangement of the reinforcing elements will be described with reference to Figures 10 to 13A and 13B.

The outermost layer of the shell 1 is formed with a conductive member 40 having a conductivity formed with leather such as cowhide, conductive resin and the like (see Figure 13B). The conductive member 40 is configured with a portion that is formed with a layer and a portion that is formed by layering the reinforcing member 50 to sandwich the reinforcing member 50 in an intermediate portion. The reinforcing member 50 is configured with a portion which is formed with a layer and a portion which is formed by being layered. The reinforcing member 50 is formed, for example, from paper such as impregnated paper made by compressing a plurality of superimposed fine papers and impregnating papers in a predetermined impregnating liquid, a metal plate and the like.

In a case where the reinforcing member 50 is sandwiched in the conductive member 40, the conductive member 40 is specified by being divided into a first layer 41 having a first conductivity and a second layer 42 having a second conductivity. The reinforcing member 50 can be specified as a third layer having a third conductivity in which the predetermined stiffness is guaranteed. The first conductivity and the second conductivity can be equal. In the case in which the first layer 41 and the second layer 42 are formed with the same material, the first conductivity and the second conductivity are equal and their manufacture is facilitated. The first layer 41 and the second layer 42 sandwiching the reinforcing element 50 and thus the shell 1 can obtain the predetermined stiffness.

For explosion-proof measurements, in particular, the conductive element 40 having the conductivity is used in the outermost layer of the shell 1, the reinforcing element 50 is also formed with paper and the like having a conductivity , and thus it is possible to guarantee a superior explosion-proof property. If the conductive element 40 is formed with leather (in particular cowhide), the conductivity is good and the feel is also good, and thus the leather is suitable for the shell 1. In this case, one of the first layer and second layer 42 is formed from leather and the other layer can be formed from another material.

The paper is used for the reinforcing element as a third layer and so

The balance of reinforcement (rigidity) and lightness is improved.

In a case where the paper has a third conductivity of a predetermined size, it is possible to guarantee a high explosion-proof property.

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

Four types of paper having different thicknesses are used for the reinforcing element 50.

The first reinforcing member 50a is the thickest and has, for example, a thickness of 2.0 mm and the second reinforcing member 50b is the second thickest and has, for example, a thickness of 1.25 mm. The third strengthening element

50c is thinner and has, for example, a thickness of 1.0 mm and the fourth reinforcing member 50d is the thinner and has, for example, a thickness of 0.6 mm. In order to improve the resistance by combining approximately each of the first to the fourth reinforcing element 50a, 50b, 50c and 50d, from the first to the fourth reinforcing element 50a, 50b, 50c and 50d can be used by being independently deposited in layers.

In FIGS. 10 to 12A to 12C, the first reinforcing element 50a is illustrated by oblique lines having small inclinations, the second reinforcing element 50b is illustrated by oblique lines lying on the left side, the third reinforcing element 50c is illustrated by transverse oblique lines and the fourth reinforcing element 50d is illustrated by oblique lines on the right side.

The first reinforcing element 50a is disposed in the edge part 33 provided along a lateral surface of the front side 30a of the cover element 30 in the longitudinal direction and a periphery of the upper opening part 20 provided in the upper lateral surface part 10cl. The second reinforcing element 50b is disposed in the entire front surface portion 10a of the body 10 comprising the projection region 26 of the lateral surface projection 25, the entire rear side 30b of the cover element 30, the surface portion rear 10b of the body 10 and a periphery of the lateral opening part 23 provided in the right and left lateral surface parts 10c3 of the body 10.

The third reinforcement element 50c is disposed in the pusher 21 provided in the upper lateral surface part 10cl of the body 10. The fourth reinforcement element 50d is disposed substantially throughout the cover element 30.

The resistance of the entire shell 1 is increased and the shock and the like against the portable electronic device 100 is prevented by designing the structure of each part and arranging the reinforcing elements 50 having different thicknesses. A specific example will be further described with reference to Figures 13A and 13B in Figures 17A to 17C.

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

1 element of reinforcement element

portable electronics 100 by providing protruding from the storage surface portion of the body 10 and therefore, the impact relative to the side apparatus 10c defining having the thick thickness it is possible to reduce portable electronics 100.

Since the outermost layer of the shell 1 is the conductive element 40, for example, the shell 1 has the flameproof structure even if the shell 1 is dropped on a metallic and similar floor and it is possible to use the portable electronic device 100 safely without causing an electrical spark and the like.

As illustrated in FIG. 14C, the second reinforcement elements 50b are arranged in order to interpose the first reinforcement element 50a and the fourth reinforcement element 50d on both sides and the four-layer laminate structure which is thicker than the other parts , is provided in the central part of the projection region 26.

The protrusion region 26 of the lateral surface protrusion 25 protrudes from the arrangement position of the cover member 30 on the outside, in the closed state in which the front surface opening portion 11 is covered by the cover element 30 also serving for the protection of the front surface opening part 11 of the body 10 and thus the impact resistance of the shell 1 is increased. Since the projection region 26 is formed with the four-layer laminate structure of the reinforcing member 50 and has a thicker thickness than the other regions of the side surface projection 25, the impact resistance is further increased.

The shell illustrated in Figures 8A and 8B is an example in which the lateral surface projection 25 projects from the lateral surface portion 10c throughout the body 10 to further increase the impact property is described, but the locations and the the number of protrusions is not limited and the lateral surface protrusion 25 can protrude from at least one side surface portion 10c. Of course, the lateral surface protrusions 25 can project from the two lateral surface portions 10c facing each other.

As illustrated in FIG. 15C, the actuator covering part 13 covering the thrust actuator 103 of the portable electronic device 100 provided in the front surface part 10a of the body 10 has an actuator region 13a, the region peripheral 13b and the adjacent region 13c adjacent to the outside with respect to the actuator region 13a. The two second reinforcing elements 50b which are the third layer sandwiched between the first layer 41 and the second layer 42 are arranged in the actuator region 13a. The third layer is rigid, has a resistance greater than that of the first layer and of the second layer and facilitates the operation of the thrust actuator 103.

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

As illustrated in FIG. 16B, the upper opening part 20 which can use the transparent element 110 and the optical interface unit 111 provided in the upper side surface 100c of the portable electronic device 100 is provided in the part of upper side surface 10cl of the body 10. The thick part 20a comprising a predetermined thickness is provided in at least part of a periphery of the upper opening part 20. At least part of the thick part 20a is arranged to overlap with the housing 101 of the periphery of the transparent element 110 of the portable electronic device 100.

The thick part 20a comprises the thick part 20a1 and the thick part 20a2 disposed on both sides of the upper opening part 20, and is formed to be thicker than the upper side surface part lOcl different from the thick part 20a.

The thick part 20al has a three-layer structure of the first layer 41 and the second layer 42 of the conductive element 40 and the first reinforcement element 50a sandwiched between the first layer 41 and the second layer 42. C ' that is, since the upper side surface portion 10cl basically has a structure with a conductive element layer 40, the thick part 20al having the three-layer structure is thicker than the upper side surface part lOcl. A laminating direction of the three-layer structure is a vertical direction away from the upper side surface portion 10cl and the upper side surface 100c of the portable electronic device 100. On the other hand, the thick part 20a2 is the projection region 26 (see FIGS. 14B and 14C) described above and a direction of lamination of the thick part 20a2 is arranged along the upper side surface part lOcl and the upper side surface 100c of the electronic apparatus portable 100. As illustrated in FIGS. 16A and 16B, the thick part 20a2 comes into contact with the housing 101 of the periphery of the transparent element 110 of the portable electronic device 100 without the upper lateral surface part 10cl.

The transparent element 110 and the optical interface unit 111 are explosion-proof and in particular, the transparent element 110 whose resistance is lower than that of the housing 101 is protected against impact and the like by providing the thick part. 20a in the periphery of the upper opening portion 20. That is, it is possible to prevent the entry of a flammable gas into the optical interface unit 111 due to the rupture of the transparent element 110 made from resin and the like. It is conceivable that the conductors of an electrical circuit are exposed to the atmosphere by shock and the like in the optical interface unit. The transparent element 110 is not broken and thus it is possible to suppress the flammable gas which comes into contact with the conductors and suppress the ignition of the inflammable gas due to the conductors supplied. Since the thick part 20a has a structure coming into contact with the housing 101 directly or via the lateral surface part 10cl, the shock received by the thick part 20a is not directly applied to the transparent element 110.

The upper opening part 20 is open so as not to overlap with the transparent element 110, but may partially overlap with the transparent element 110.

As illustrated in FIGS. 16A and 16C, the pusher 21 covering the push-type actuator 112 of the portable electronic device 100 is provided adjacent to the upper opening part 20. In particular, the pusher 21 is arranged between the upper opening part 20 and the thick part 20al. The third reinforcing element 50c is sandwiched between the first layer 41 and the second layer 42 in the pusher 21. The entire thickness of the thick part 20a is defined as the first thickness and the entire thickness of the 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 the cases among which the first thickness and the second thickness are equal, 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, manufacture is facilitated, if the first thickness is thicker than the second thickness, the protective resistance of the actuator 112 is improved, and if the first thickness is thinner than the second thickness, the actuator 112 is easily actuated.

As illustrated in Figures 12B, 12C and the like, the side opening portions 23 exposing the actuators 130 and 140 respectively which are the pushable physical keys of the portable electronic device 100 are provided in the right side surface portions and left 10c3 of body 10 and have the same configuration. Thus, the left side surface portion 10c3 and the actuator 130 will be described in Figures 17A to 17C.

Similar to the upper opening part 20, the thick part 23a is provided in the periphery of the lateral opening part 23. The first thick part (thick part) 23al arranged along the longitudinal direction of the lateral surface part left 10c3 has a three-layer structure in which the second reinforcing element 50b is sandwiched between the conductive elements 40 (the first layer 41 and the second layer 42). The first thick part 23al is thicker than the thickness of the lateral surface part 10c. On the other hand, the second thick part (thick part) 23a2 disposed along the lateral direction of the left lateral surface part 10c3 is configured with the conductive element 40. A first thickness of the first thick part 23al is formed for be greater than a second thickness of the thick second part 23a2 and reduce the shock from the outside. The actuators 130 and 140 are explosion-proof by providing a conductive element 40 having a conductivity in the periphery of the operators 130 and 140. That is to say that even in a case in which a charged human body (for example: the finger) tries to come into contact with the actuators 130 and 140 and the like, the human body comes into contact with the conductive element 40 of the periphery so that the charged electric charge escapes from the conductive element 40 having a predetermined conductivity and then the human body comes into contact with the operators 130 and 140. Therefore, it is possible to suppress the loading of the actuators 130 and 140. Thus, it is possible to suppress the ignition of the gas and the like due to the loading of the actuators 130 and 140. The second thick part 23a2 is likely to come into contact with the finger of the user who is trying to gain access to the lateral opening part 23, but is formed ée to be thinner than the first thick part 23al and thus has little chance of interfering with access.

In the embodiment, the thick part 20a and the thick part 23a are configured by a laminated structure of the conductive element 40 and

The reinforcing element 50, but the thick parts

20a and 23a can be configured by the first layer and the second layer 42 of the conductive element 40.

The taking case in which the foreign bodies storing the electronic device fall, it is possible to absorb strap 15 is arranged on the side in consideration the ease the user and the absorption of shocks is guaranteed by the damping element 16 disposed on the upper side from the strap 15.

As illustrated in FIG. 18B, if the portable electronic device 100 is stored in the body 10, the shell 1 is naturally inclined to the left or right side due to the weight of the portable electronic device 100 and the shock due to the Falling foreign bodies from the outside onto the portable electronic device 100 is reduced. That is, the portable electronic device 100 is supported and fixedly disposed on a portion of the rear surface portion 10b of the body 10 on one end side or the other end side relative to to the rear surface projection 17 and the rear surface of the rear surface projection 17 and the shock is reduced by an elastic force of the rear surface projection 17. In FIG. 18B, the damping element 16 is not not illustrated, but the latter is simply concealed by the shadow and the body 10 also includes the damping element 16 in FIG. 18B.

As described above, the resistance of the whole shell 1 is increased and the portable electronic device 100 stored is protected against impact and the like by designing the structure of each part of the shell 1 and having reinforcing elements 50 having different thicknesses. In particular, the portable electronic device 100 used at a construction site, a work site, a security processing site, a factory inspection site and the like is heavier than a normal mobile phone and a fall impact force is also important. The deflagration property and impact resistance of the portable electronic device 100 are improved by a combination of the lamination of the conductive member 40 and the reinforcing member 50. The thicknesses of the thick portions 20a and 23a are modified, and explosion-proof measurements are made in the actuators 112, 130 and 140 and the operability is improved.
