[0022] 2 to 5, the battery cover 10 is configured to openably cover the opening 11a of the battery storage section 11, and the edges of the upper side are engaged by a pair of mounting levers 13, so that the battery cover 10 is attached to the rear surface of the lower case 3 in a state corresponding to the key operation section 5. The battery cover 10 is also provided with a fulcrum protrusion (not shown) at the end of the lower side, and is configured to rotate about the fulcrum protrusion to open and close the battery storage section 11.

[0023] 1 to 3, a grip portion 14 that can be grasped with one hand of a user is provided in the narrow portion 1b located on the lower side of the device case 1, spanning the front surface, which is the first surface, of the device case 1 and the back surface, which is the second surface located on the opposite side. This grip portion 14 is configured so that it can be grasped with one hand of the user in a grasping manner in which the thumb F1 of the user's hand covers the front surface of the device case 1 and the other fingers F2 to F5 extending from the side of the device case 1 support the back surface of the device case 1.

[0024] 1 to 3, the grip portion 14 is made up of a narrow portion of the upper case 2, which is the narrow portion 1b of the device case 1, a narrow portion of the lower case 3, and a battery cover 10 of the lower case 3. In this case, the side surfaces of the narrow portion of the upper case 2 and the narrow portion of the lower case 3 in the grip portion 14 are formed into arc-shaped curved surfaces that naturally curve the hand of the user grasping the grip portion 14 in the above-described grasping manner. In addition, the battery cover 10 of the lower case 3 is formed into a curved shape that gently curves and protrudes from both sides of the lower case 3 toward the back side.

[0025] As a result, as shown in Figures 1 to 3, when the user places his / her thumb F1 over the surface of the device case 1 to operate the key operation unit 5 and supports the back surface of the device case 1 with the other fingers F2 to F5 extended from the sides of the device case 1, the grip portion 14 is formed in a shape that allows the user's other fingers F2 to F5 to naturally bend and wrap around the back surface of the device case 1.

[0026] For this reason, as shown in Figures 1 to 3, when a user holds the device case 1 in one hand in a grasping manner in which the user places the thumb F1 over the surface of the device case 1 and supports the backside of the device case 1 with the other fingers F2 to F5 extended from the side of the device case 1 in order to operate the key operation unit 5 with the thumb F1, the grip portion 14 is formed in a shape that fits the user's grasping hand and makes it easy for the user to hold in one hand regardless of the size of the user's hand.

[0027] Furthermore, the battery cover 10 located on the back side of this grip portion 14 is provided with a finger hook protrusion 15 that protrudes into a shape that creates a bulge between the index finger F2 and middle finger F3 of the user's gripping hand when the user holds the device case 1 in one hand in a grasping manner in which the user places the thumb F1 over the surface of the device case 1 and supports the back side of the device case 1 with the other fingers F2 to F5 extended from the side of the device case 1, as shown in Figures 2, 3, and 5.

[0028] 2, 3, and 5, a recess 16 is provided on the back surface of the device case 1, recessed between the grip portion 14 and the other end of the device case 1 located on an extension of the grip portion 14. In other words, the recess 16 is provided in a recessed state between the finger hook protrusion 15 of the battery cover 10 and the reading protrusion 6a of the optical reading unit 6.

[0029] 2, 3, and 5, when the user holds the grip portion 14 with one hand in a grasping manner in which the user supports the rear surface of the device case 1 with the thumb F1 and the other fingers F2 to F5 extended from the side of the device case 1 to operate the key operation unit 5 with the thumb F1, the finger hook protrusion portion 15 has a mountain-shaped top portion 15a that is located between the index finger F2 and middle finger F3 of the user's grasping hand. The top portion 15a is located between the index finger F2 and middle finger F3 of the user's grasping hand and is formed in a curved shape that continues along the bent shape of the index finger F2 and middle finger F3.

[0030] 2, 3, and 5, the top 15a continues in a curved shape along the bent shape of the index finger F2 and the middle finger F3 in the horizontal direction perpendicular to the longitudinal direction of the device case 1, and is formed so that the intermediate part in the horizontal direction of the continuation protrudes the most toward the back surface of the device case 1, and the protruding length gradually decreases from the intermediate part in the horizontal direction toward both sides in the horizontal direction. The finger hook protrusion 15 also includes a first finger hook region 17 which is the base of one side of the top 15a, and a second finger hook region 18 which is the base of the other side of the top 15a.

[0031] 2, 3, and 5, first finger rest area 17 is a first inclined surface against which index finger F2 presses when the user grasps grip portion 14 in the above-described grasping manner, and is formed as a steeply inclined surface from the upper side of battery cover 10 toward top 15a. Second finger rest area 18 is an inclined surface against which middle finger F3 to little finger F5 press when the user grasps grip portion 14 in the above-described grasping manner, and is formed as a gently inclined surface from top 15a toward the lower side of battery cover 10.

[0032] That is, as shown in Figures 2, 3, and 5, when the user holds the device in such a manner that the thumb F1 covers the key operation unit 5 and the other fingers F2 to F5 extended from the side of the device case 1 support the back surface of the device case 1 in order to operate the key operation unit 5 with the thumb F1, the first finger rest area 17 is formed on an inclined surface so that the pad of the index finger F2 of the user's holding hand is pressed against the lower edge side of the battery cover 10 in the vertical direction (longitudinal direction), i.e., toward the user's holding hand.

[0033] 2, 3, and 5, the first finger hook region 17 is also the inclined surface of the recessed portion 16 located on the grip portion 14 side, and is formed as an inclined surface rising at a steep angle from the upper edge located on the upper edge side of the battery cover 10 toward the vertex 15a. The first finger hook region 17 is curved in an arc shape corresponding to the bent state of the index finger F2 along the vertex 15a that continues in the horizontal direction perpendicular to the vertical direction (longitudinal direction) of the device case 1.

[0034] For this reason, as shown in Figures 2, 3, and 5, this finger hook protrusion portion 15 is configured so that when the user grasps the grip portion 14 in a grasping manner in which the user places the thumb F1 over the key operation portion 5 and supports the back surface of the device case 1 with the other fingers F2 to F5 extended from the side of the device case 1, the user's index finger F2 is bent along the curvature of the first finger hook area 17, and the pad of the index finger F2 is pressed against the first finger hook area 17, and in this state the first finger hook area 17 is pulled toward the lower side of the device case 1 in the vertical direction, i.e., toward the hand that is grasping the device case 1.

[0035] On the other hand, as shown in Figures 2, 3 and 5, when the user grasps the grip portion 14 in such a manner that the user places the thumb F1 over the key operation portion 5 to operate the key operation portion 5 and supports the back surface of the device case 1 with the other fingers F2 to F5 extended from the side of the device case 1, the pads of the fingers F3 to F5 of the user's grasping hand press the battery cover 10 of the grip portion 14 against the device case 1, and the second finger holding area 18 is formed into a curved surface such that the user's middle finger F3 to little finger F5 are lined up and naturally bent.

[0036] 2, 3, and 5, second finger rest area 18 is formed into a curved surface that gently slopes from top 15a toward the lower side of battery cover 10. As a result, second finger rest area 18 is formed into a gently curved shape that convexly curves toward the back side of battery cover 10 so that when a user grasps grip portion 14 in a grasping manner in which the user places thumb F1 over key operation unit 5 and supports the back side of device case 1 with other fingers F2 to F5 extended from the side of device case 1, the fingers F3 to F5 other than index finger F2 are aligned and bent in a natural manner.

[0037] 1 to 5, the grip portion 14 of the device case 1 is formed in a shape that is symmetrical with respect to the center position in the lateral direction of the device case 1. This allows the user to hold the grip portion 14 in the same way with either the right hand or the left hand.

[0038] 2 to 5, a bottom trigger key 20 is provided in a recess 16 at a location close to the top edge of the battery cover 10 on the lower case 3 of the device case 1. This bottom trigger key 20 is a switch unit for causing the optical reading unit 6 to perform a reading operation, similar to the top trigger key 5a and side trigger key 8 of the key operation unit 5.

[0039] As shown in Figures 6 to 12, this underside trigger key 20 comprises a button portion 21, an elastic member 22, a switch board 23, and a pressure plate 24, and is attached in a state in which the button portion 21, the elastic member 22, and the switch board 23 are pressed against the inner surface of the lower case 3 by the pressure plate 24.

[0040] In this case, the button portion 21 of the underside trigger key 20 and the first fingerhold area 17, which is the first inclined surface of the fingerhold protrusion portion 15 of the grip portion 14, are spaced apart so that the index finger F2 of the user's gripping hand can be positioned when the user grips the grip portion 14 with one hand in the above-described gripping manner, as shown in FIG. 3 .

[0041] 6 to 9, the button portion 21 of this lower trigger key 20 comprises a button body 25 and a head portion 26. The button body 25 comprises a seat portion 25a integrally formed with the head portion 26, a pair of arms 25b extending from the seat portion 25a, and a shaft portion 25c provided between the tips of the pair of arms 25b. In this case, the outer periphery of the seat portion 25a is formed larger than the inner periphery of a button hole 27 provided on the inner surface of the lower case 3.

[0042] As a result, as shown in Figures 6 to 9, the button body 25 is arranged in a state where the seat portion 25a corresponds to the button hole 27 provided on the inner surface of the lower case 3, and the shaft portion 25c is rotatably arranged on the shaft holding portion 28 provided on the inner surface of the lower case 3 on the opposite side of the finger hook protrusion portion 15 of the grip portion 14, sandwiching the button hole 27 of the lower case 3, so that the outer peripheral edge of the seat portion 25a abuts against the inner peripheral edge of the button hole 27 of the lower case 3 in a manner that allows it to come into and out of contact with it.

[0043] As shown in Figures 6 to 9, the head 26 is provided on the seat portion 25a of the button body 25, and is inserted into the button hole 27 of the lower case 3 from the inside to the outside of the lower case 3, and is configured to rotate and move in the vertical direction together with the rotation of the button body 25 around the shaft portion 25c of the button body 25.

[0044] 6 to 9, a second inclined surface 26a is provided on the upper surface of head 26. Second inclined surface 26a is higher at one end of grip portion 14 on the finger hook protrusion 15 side and gradually decreases toward the other end opposite finger hook protrusion 15, with the second inclined surface 26a being provided at approximately the same inclination as first finger hook region 17 of finger hook protrusion 15.

[0045] As a result, as shown in Figures 6 to 9, the head 26 of the button portion 21 is inserted into the button hole 27 of the lower case 3 from the inside to the outside of the lower case 3, and in this state the shaft portion 25c of the button body 25 is rotatably arranged on the shaft holding portion 28 provided on the inner surface of the lower case 3, and the outer peripheral edge of the seat portion 25a is configured to abut against the inner peripheral edge of the button hole 27 of the lower case 3 in a manner that allows it to come into and out of contact with it.

[0046] In this case, as shown in Figures 6 to 9, the height of the button portion 21 protruding from the button hole 27 of the lower case 3 to the outside of the lower case 3 is lower than the height of the first finger hook area 17, which is the first inclined surface of the finger hook protrusion 15 of the grip portion 14, and is formed to be, for example, approximately half the height of the first finger hook area 17, which is the first inclined surface of the finger hook protrusion 15.

Each of the mounting portions 41 includes a screw insertion hole 41a into which a screw (not shown) is inserted, and a rib portion 41b provided in a substantially C-shape around the screw insertion hole 41a. In this case, the rib portion 41b is formed slightly higher than the thickness of the switch board 23.

[0060] 6 to 8 and 12, when the presser plate 24 is positioned on the inner surface of the lower case 3 by the pair of presser plate positioning parts 40, the multiple mounting parts 41 are arranged to correspond to the multiple fixing parts 42 provided on the inner surface of the lower case 3. In this case, the multiple fixing parts 42 are boss parts having screw holes 42a provided on the outside of the four corners of the annular groove part 29 provided on the inner surface of the lower case 3, as shown in FIG.

[0061] As a result, as shown in Figures 6 to 8 and 12, when the multiple mounting portions 41 correspond to the multiple fixing portions 42 provided on the inner surface of the lower case 3, the rib portions 41b of the mounting portions 41 abut against the fixing portions 42 of the lower case 3, and the screw insertion holes 41a of the mounting portions 41 correspond to the screw holes 42a of the fixing portions 42 of the lower case 3.

[0062] As shown in Figures 6 to 8 and 12, this pressure plate 24 is configured to press down on the switch board 23 and attach to the inner surface of the lower case 3 by inserting screws (not shown) into the screw insertion holes 41a of the mounting parts 41 and screwing them into the screw holes 42a of the fixing parts 42 and tightening them, with the multiple mounting parts 41 corresponding to the multiple fixing parts 42 provided on the inner surface of the lower case 3.

[0063] 6 to 8 and 12, the presser plate 24 is further provided with connection holes 43 corresponding to the pair of connection terminals 37 of the switch board 23. A connection member 44 such as an interconnector is arranged inside the connection holes 43. The connection member 44 electrically connects the pair of connection terminals 37 of the switch board 23 to a circuit board 45 inside the device case 1.

[0064] Next, the operation of such a portable terminal will be described. First, we will explain how to attach the bottom trigger key 20 to the lower case 3. In this case, the button portion 21 is placed on the inner surface of the lower case 3. At this time, the head portion 26 of the button portion 21 is inserted into the button hole 27 of the lower case 3 from inside the lower case 3, and in this state, the shaft portion 25c of the button body 25 is placed in the shaft holding portion 28 of the lower case 3.

[0065] As a result, button portion 21 is arranged to be rotatable in the vertical direction around shaft portion 25c with head portion 26 protruding from inside lower case 3 to the outside. In this state, second inclined surface 26a of head portion 26 protruding from lower case 3 is arranged approximately parallel to and at the same inclination as first finger hook region 17 of finger hook protrusion 15 in grip portion 14 of device case 1.

[0066] In this case, the button portion 21 of the underside trigger key 20 is positioned with a distance between it and the first fingerhold area 17, which is the first inclined surface of the fingerhold protrusion portion 15 of the grip portion 14, such that when the user grasps the grip portion 14 with one hand in the above-mentioned grasping manner, the index finger F2 of the user's grasping hand will be positioned there.

[0067] In this state, the elastic member 22 is attached to the inner surface of the lower case 3. In this case, first, the bulge 31 provided on the elastic sheet portion 30 is aligned with the pressing protrusion 25d of the button portion 21, and the shaft pressing portion 32 provided on the elastic sheet portion 30 is aligned with the shaft portion 25c of the button portion 21. In this state, the frame-shaped packing portion 34 provided on the outer periphery of the elastic sheet portion 30 is fitted into a groove portion 29 provided on the inner surface of the lower case 3 so as to surround the button hole 27 and the shaft holding portion 28.

[0068] As a result, the elastic member 22 is attached to the inner surface of the lower case 3. In this case, when the packing portion 34 is fitted into the groove portion 29 on the inner surface of the lower case 3, the elastic sheet portion 30 is arranged to cover the inside surrounded by the groove portion 29 of the lower case 3. Therefore, the lower trigger key 20 is made waterproof by the elastic member 22.

[0069] At this time, the pressing protrusion 25d of the button 21 is elastically fitted into the hole 31a provided in the bulge 31 of the elastic sheet 30. As a result, the bulge 31 of the elastic member 22 elastically deforms in accordance with the rotation of the button 21. At this time, the shaft pressing portion 32 of the elastic sheet 30 elastically presses the shaft 25c of the button 21 so as to allow it to rotate.

[0070] In this state, the switch board 23 is placed on the inner surface of the lower case 3. At this time, first, the pair of board positioning portions 38 of the switch board 23 are aligned with the pair of positioning pins 39 of the lower case 3, and the pair of positioning pins 39 are inserted into the pair of board positioning portions 38. As a result, the switch board 23 is positioned on the inner surface of the lower case 3 with the elastic member 22 covering it.

[0071] As a result, the switch element 35 of the switch board 23 comes into contact with the switch pressing portion 31a in the bulge 31 of the elastic member 22. At this time, the chip component 36 of the switch board 23 is disposed in the relief recess 33 of the elastic member 22 in correspondence with the relief recess 33.

[0072] In this state, the presser plate 24 is attached to the inner surface of the lower case 3. At this time, first, the pair of presser plate positioning portions 40 of the presser plate 24 are aligned with the pair of board positioning portions 38 of the switch board 23, and in this state, the pair of positioning pins 39 of the lower case 3 inserted into the pair of board positioning portions 38 of the switch board 23 are inserted into the pair of presser plate positioning portions 40 of the presser plate 24. In this way, the presser plate 24 is positioned.

[0073] As a result, the connection holes 43 of the presser plate 24 correspond to the pair of connection terminals 37 of the switch board 23, and the multiple mounting portions 41 of the presser plate 24 correspond to the multiple fixing portions 42 provided on the inner surface of the lower case 3. As a result, the rib portions 41a of the multiple mounting portions 41 of the presser plate 24 are pressed against the multiple fixing portions 42 provided on the inner surface of the lower case 3, and the screw insertion holes 41a of the multiple mounting portions 41 of the presser plate 24 correspond to the screw holes 42a of the multiple fixing portions 42 of the lower case 3.

[0074] In this state, screws (not shown) are inserted into the screw insertion holes 41a of the multiple mounting portions 41 of the presser plate 24, and then screwed into the screw holes 42a of the multiple fixing portions 42 of the lower case 3 and tightened. As a result, the presser plate 24 presses down on the switch board 23 and is attached to the inner surface of the lower case 3.

[0075] At this time, switch board 23 pressed by press plate 24 presses elastic member 22 against the inner surface of lower case 3, and shaft pressing portion 32 of elastic member 22 rotatably presses shaft portion 25c of button portion 21. As a result, switch board 23, elastic member 22, and button portion 21 are pressed and attached against the inner surface of lower case 3 by press plate 24. In this state, one end of connecting member 44 is inserted into connection hole 43 of press plate 24 and pressed against a pair of connecting terminals 37 of switch board 23.

[0076] Then, by pressing the other end of this connection member 44 against the circuit board 45 inside the device case 1, the pair of connection terminals 37 of the switch board 23 and the circuit board 45 inside the device case 1 are electrically connected by the connection member 44. In this way, the bottom trigger key 20 is assembled to the lower case 3.

[0077] Furthermore, when attaching the battery lid 10 to the back surface of the device case 1, i.e., the back surface of the lower case 3, the battery lid 10 is attached so as to correspond to the battery storage section 11 provided in the narrow width section 1b of the device case 1. At this time, a fulcrum protrusion (not shown) on the bottom edge of the battery lid 10 is inserted into the inside of the bottom edge of the battery storage section 11 to lock it in place, and the battery lid 10 is then rotated around the fulcrum protrusion of the locked battery lid 10 to place it in the lower case 3.

[0078] Then, the edges of the battery cover 10 correspond to a pair of mounting levers 13 provided on the back surface of the lower case 3. Therefore, by rotating the pair of mounting levers 13, the edges of the battery cover 10 are pressed against and locked by the pair of mounting levers 13 against the back surface of the lower case 3. In this way, the battery cover 10 is attached to the back surface of the lower case 3, covering the battery storage section 11. In this way, a grip portion 14 is provided on the device case 1.

[0079] In this state, the first finger hook region 17 of the finger hook protrusion 15 of the grip portion 14 and the button portion 21 of the underside trigger key 20 are arranged at a predetermined distance, that is, at a distance where the index finger F2 of the user's grasping hand will be positioned when the user grasps the grip portion 14 with one hand in the above-described grasping manner. Also, in this state, the second inclined surface 26a provided on the head portion 26 of the button portion 21 and the inclined surface of the first finger hook region 17 of the finger hook protrusion 15 are arranged substantially parallel with the same inclination.

[0080] Next, a case where such a mobile terminal is used will be described. In this case, the user holds the device case 1 with one hand by grasping the grip portion 14 at the location of the battery cover 10. That is, in order to operate the key operation unit 5 with the thumb F1, the user grasps the grip portion 14 with one hand in such a manner that the thumb F1 covers the key operation unit 5 and the other fingers F2 to F5 extending from the side of the device case 1 support the back surface of the device case 1.

[0081] At this time, the thumb F1 is placed on the key operation section 5 on the surface of the device case 1, and the top 15a of the finger hook protrusion 15, which is shaped to create a bulge, is placed between the index finger F2 and middle finger F3 of the user's grasping hand.In this state, the pad of the index finger F2 is pressed against the first finger hook area 17, which is the first inclined surface of the finger hook protrusion 15 of the battery cover 10 located on the back side of the device case 1, and the pads of the other fingers F3 to F5 are placed on the second finger hook area 18 of the finger hook protrusion 15.

[0082] In this state, in order for the user to operate the key operation unit 5 with the thumb F1, the user places the thumb F1 over the key operation unit 5 and supports the back of the device case 1 with the other fingers F2 to F5 extended from the sides of the device case 1, and presses the pad of the index finger F2 of the grasping hand against the inclined surface of the first finger hook area 17 of the finger hook protrusion 15 of the battery cover 10, and in this state, the first finger hook area 17 is directed toward the bottom side of the device case 1, i.e., the side of the user's grasping hand, and the index finger F2 of the grasping hand is pulled in.

[0083] In this case, when the pad of the index finger F2 is pressed against the inclined surface of the first finger-hold area 17 of the finger-hold protrusion 15 of the battery cover 10 and is drawn toward the bottom side of the device case 1, i.e., toward the user's grasping hand, the index finger F2 is naturally bent along the curve of the first finger-hold area 17 and pressed against it. At this time, the index finger F2 of the user's grasping hand is positioned between the first finger-hold area 17 and the button 21 of the lower surface trigger key 20. In this state, the button 21 of the lower surface trigger key 20 is not operated by the index finger F2 of the user's grasping hand.

[0084] Also, at this time, in order for the user to operate the key operation unit 5 with the thumb F1, the user places the thumb F1 over the key operation unit 5 and supports the back surface of the device case 1 with the other fingers F2 to F5 extended from the sides of the device case 1, with the pads of the other fingers F3 to F5 of the user's gripping hand being pressed against the second fingerhold region 18 of the fingerhold protrusion 15. In this state, the fingers F3 to F5 are arranged side by side in a state where they are naturally bent along the curve of the second fingerhold region 18.

[0085] As a result, with the crown 15a of the bulging finger hook protrusion 15 positioned between the index finger F2 and middle finger F3 of the user's grasping hand, the middle finger F3 to little finger F5 are positioned side by side in the second finger hook region 18, naturally curved so as to wrap around the second finger hook region 18 of the finger hook protrusion 15. Therefore, the fingers F3 to F5 are positioned stably and favorably along the curved surface of the second finger hook region 18. This allows the user to reliably and favorably grasp the grip portion 14 of the device case 1 with one hand.

[0086] In this way, when the user grasps the grip portion 14 of the device case 1, the grip portion 14 is provided in the narrow portion 1b of the device case 1 and is formed in a curved shape that gently curves and protrudes from both sides of the grip portion 14 toward the back side, so that the user can securely and comfortably grasp the grip portion 14 of the device case 1 with the hand that is holding it, and the user's hand can fit into the grip portion 14.

[0087] Furthermore, when a user holds the grip portion 14 of the device case 1 with one hand, the user can securely and comfortably hold the grip portion 14 of the device case 1 with either the right or left hand because the grip portion 14 is formed in a shape that is symmetrical about the center position in the lateral direction of the device case 1. In this case, too, the lower surface of the grip portion 14 is formed in a gently curved, protruding shape, so that the user's grasping hand fits snugly around the grip portion 14 when holding the grip portion 14 of the device case 1 with one hand.

[0088] In this way, when the user grips the grip portion 14 of the device case 1, the thumb F1 is positioned on the key operation portion 5 without blocking the display portion 4, so that while looking at the information displayed on the display portion 4, the user can freely move the thumb F1 on the key operation portion 5 to operate the keys on the key operation portion 5 smoothly, and can also move the thumb F1 to the side of the device case 1 to operate the side trigger key 8.

[0089] Furthermore, when the user operates the lower surface trigger key 20 while gripping the grip portion 14 of the device case 1, the user moves the fingertip of the index finger F2 of the grasping hand to the head 26 of the button portion 21 of the lower surface trigger key 20. At this time, the height of the button portion 21 is low, about half the height of the first finger hook region 17 of the finger hook protrusion 15, so the fingertip of the index finger F2 of the grasping hand can be easily moved to the head 26 of the button portion 21 of the lower surface trigger key 20.

[0090] Then, the user can move the index finger F2 of the grasping hand to the head 26 of the button 21 and press the head 26 of the button 21 in a pulling manner. At this time, because the upper surface of the head 26 of the button 21 is formed as the second inclined surface 26a having the same inclination as the inclined surface of the first finger-hook region 17 of the finger-hook protrusion 15, the button 21 of the lower-surface trigger key 20 can be easily operated with the index finger F2 by pressing the head 26 in a pulling manner with the fingertip of the index finger F2 of the grasping hand.

[0091] That is, when the button portion 21 of the lower trigger key 20 is pressed by the fingertip of the index finger F2 of the user's grasping hand, the button portion 21 rotates around the shaft portion 25c of the button body 25, and the pressing protrusion 25d of the button body 25 presses the bulging portion 31 of the elastic member 22, causing the bulging portion 31 to elastically deform and collapse. Then, the switch pressing portion 31a in the bulging portion 31 presses the switch element 35 of the switch board 23 to turn it on.

[0092] In this way, when the bottom trigger key 20 is turned on, the optical reading unit 6 provided on the back surface of the wide portion 1a of the device case 1 is activated, and the laser reading unit emits a laser beam from the first window 6b of the reading protrusion 6a to the outside of the device case 1, and receives the reflected light of the laser beam to read the barcode of the item, etc. At this time, the imaging unit of the optical reading unit 6 also takes an image of the item to be read by the laser reading unit through the second window 6c.

[0093] Incidentally, when the index finger F2 of the user's grasping hand is positioned between the first fingerhold area 17 and the button portion 21 of the lower trigger key 20, even if the back of the index finger F2 of the user's grasping hand, i.e., the back opposite the pad of the index finger F2, comes into contact with or is pressed against the button portion 21 of the lower trigger key 20, the button portion 21 will not rotate around the shaft portion 25c of the button body 25.

[0094] That is, the button 21 of the lower surface trigger key 20 rotates at the other end thereof around the shaft 25c provided at one end of the button 21 opposite the first fingerhold region 17 of the fingerhold protrusion 15, so that even if the back of the index finger F2 of the user's grasping hand comes into contact with or presses against the button 21, the button 21 of the lower surface trigger key 20 will not be inadvertently operated by the index finger F2 of the user's grasping hand. This prevents the lower surface trigger key 20 from being accidentally operated by the index finger F2 of the user's grasping hand.

[0095] As described above, this mobile terminal comprises device case 1, which is the terminal main body having grip section 14 provided with finger hook protrusion 15 having first finger hook area 17, which is a first inclined surface against which the index finger F2 of the user's hand is pressed when the mobile terminal is held in one hand, and bottom trigger key 20, which is a switch section having button section 21 provided opposite first finger hook area 17 on the first finger hook area 17 side of finger hook protrusion 15, and provided with second inclined surface 26a having approximately the same inclination as the inclined surface of first finger hook area 17, making it easy to hold with one hand and improving the operability of bottom trigger key 20.

[0096] That is, with this mobile terminal, when the user grasps the grip portion 14 with one hand, the index finger F2 of the grasping hand can be pressed against the first fingerhold area 17 of the fingerhold protrusion 15, so that the grip portion 14 can be grasped securely and properly. Even when the grip 14 is grasped in this way, the button portion 21 of the underside trigger key 20 will not be operated as a switch by the index finger F2 of the grasping hand, so that the erroneous operation of the underside trigger key 20 can be prevented.

[0097] Furthermore, with this mobile terminal, when the user operates the lower trigger key 20 while grasping the grip portion 14 with one hand, by moving the fingertip of the index finger F2 of the grasping hand to the button portion 21 of the lower trigger key 20, the user can place the fingertip of the index finger F2 of the grasping hand against the second inclined surface 26a of the button portion 21. This allows the user to operate the second inclined surface 26a of the button portion 21 by pulling the fingertip of the index finger F2 of the grasping hand toward it, making it possible to easily and satisfactorily operate the button portion 21 of the lower trigger key 20 and thereby improving the operability of the lower trigger key 20.

[0098] In this case, the grip portion 14 is configured so that when the user grasps it with his / her hand, the thumb F1 of one hand covers the top surface, which is the first surface of the device case 1, and the user's other fingers F2 to F5 naturally wrap around from the side of the device case 1 to the bottom surface, which is the second surface of the device case 1, the index finger F2 of the user's hand is pressed against the first fingerhold area 17 of the fingerhold protrusion 15, thereby allowing the user to grasp the grip portion 14 well with one hand.

[0099] Furthermore, in this mobile terminal, the first finger hook area 17 of the finger hook protrusion 15 of the grip section 14 and the button section 21 of the underside trigger key 20 are spaced apart so that the index finger F2 of the user's grasping hand can be positioned when the user grasps the grip section 14 with one hand in the above-described grasping manner. Therefore, when the user grasps the grip section 14 with one hand, the index finger F2 of the user's grasping hand can be positioned well between the first finger hook area 17 of the finger hook protrusion 15 and the button section 21 of the underside trigger key 20, thereby preventing the underside trigger key 20 from being inadvertently switched on by the index finger F2 of the user's grasping hand.

[0100] Furthermore, in this mobile terminal, the button portion 21 is formed lower than the height of the finger hook protrusion 15. Therefore, when the user operates the underside trigger key 20 while grasping the grip portion 14 with one hand, the height of the button portion 21 is lower than the height of the finger hook protrusion 15, so that the user can easily move the fingertip of the index finger F2 of the grasping hand to the button portion 21 of the underside trigger key 20. This allows the fingertip of the index finger F2 of the grasping hand to be easily and satisfactorily placed on the second inclined surface 26a of the button portion 21, thereby improving the operability of the underside trigger key 20.

[0101] Furthermore, the button portion 21 of this underside trigger key 20 rotates at the other end side of the finger hook protrusion 15, with one end side opposite the finger hook protrusion 15 as a fulcrum. Therefore, even if the index finger F2 of the user's hand holding the grip portion 14 with one hand is pressed against the first finger hook area 17 of the finger hook protrusion 15 and the index finger F2 of the user's holding hand comes into contact with or presses against the button portion 21, the button portion 21 will not rotate at the one end side opposite the finger hook protrusion 15 as a fulcrum. This also prevents the underside trigger key 20 from being inadvertently switched on by the index finger F2 of the user's holding hand.

[0102] In addition, in this mobile terminal, the bottom trigger key 20 is provided with an elastic member 22 that is elastically deformed when pressed by the button portion 21, and this elastic member 22 also has waterproofing properties that make the bottom trigger key 20 waterproof.Therefore, even if water enters between the head 26 of the button portion 21 and the button hole 27 provided in the lower case 3 of the device case 1, the elastic member 22 can prevent this infiltrating water from entering the device case 1, thereby making the bottom trigger key 20 waterproof.

[0103] Furthermore, this mobile terminal is provided with a battery cover 10 that is attached to the device case 1 and opens and closes the battery storage section 11 that is provided inside the device case 1 and opens on the underside, which is the second surface side of the grip section 14, and that forms the underside of the grip section 14.As a result, a finger hook protrusion 15 can be provided on the battery cover 10, so that the shape of the device case 1 having the grip section 14 does not become complex, and the shape of the device case 1 can be simplified.

[0104] Furthermore, this mobile terminal is equipped with a device case 1 having a grip section 14 provided with a finger hook protrusion 15 having a first finger hook area 17 which is a first inclined surface against which the index finger F2 of the user's grasping hand is pressed when the device case 1 is held with one hand, and a bottom trigger key 20 which is provided on the device case 1 on the first finger hook area 17 side of the finger hook protrusion 15 so as to face the first finger hook area 17, and which prevents the index finger F2 from pressing against the first finger hook area 17 to operate the switch of the button section 21. This makes the device easy to hold with one hand and improves the operability of the bottom trigger key 20.

[0105] That is, with this mobile terminal, when the user grasps the grip portion 14 with one hand, the index finger F2 of the grasping hand can be pressed against the first fingerhold area 17 of the fingerhold protrusion 15, so that the grip portion 14 can be grasped securely and properly. In this way, when the user grasps the grip 14, the index finger F2 pressed against the first fingerhold area 17 will not operate the button portion 21 of the underside trigger key 20 as a switch, so that the erroneous operation of the underside trigger key 20 can be prevented.

[0106] Furthermore, with this mobile terminal, when the user operates the lower trigger key 20 while holding the grip portion 14 with one hand, the user can easily and satisfactorily operate the button portion 21 of the lower trigger key 20 by moving the fingertip of the index finger F2 of the holding hand to the button portion 21 of the lower trigger key 20, thereby improving the operability of the lower trigger key 20.

[0107] In the above-described embodiment, the display unit 4 and the key operation unit 5 are provided on the surface of the device case 1, but the present invention is not limited to this. For example, the key operation unit may be formed of a transparent touch panel and the input display unit may be formed by stacking a display panel on top of it.
