In this state, the switch holding portion 20c is attached to the inner surface of the battery lid 10 by a screw 23a. As a result, the lower surface trigger key 20 is attached to the inner surface of the battery lid 10.

Then, the battery lid 10 to which the lower surface trigger key 20 is attached is attached to the back surface of the equipment case 1 to cover the battery storage portion 11 provided in the narrow portion 1b of the equipment case 1. At this time, the fulcrum protrusion 10a on the lower side of the battery lid 10 is inserted into the inside of the lower side of the battery storage portion 11 to be locked, and the fulcrum protrusion 10a of the locked battery lid 10 is used as a fulcrum for the battery. The lid 10 is rotated together with the lower surface trigger key 20 to arrange the extension portion 17a of the upper side portion of the battery lid 10 on the lid holding portion 23 of the lower case 3.

Then, the edge portion of the extension portion 17a of the battery lid 10 corresponds to the 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 edge portion of the battery lid 10 is pressed against the back surface of the lower case 3 by the pair of mounting levers 13 to be locked. As a result, the battery lid 10 covers the battery housing portion 11 and is attached to the back surface of the lower case 3.

At this time, the switch board 25 of the lower surface trigger key 20 is electrically connected to the circuit board 22 by the contact pin 22a. That is, the switch board 25 of the switch body 20a of the lower surface trigger key 20 is extended and arranged on the lower surface of the switch holding portion 20c when the battery lid 10 covers the battery housing portion 11 and is attached to the back surface of the lower case 3. The switch board 25 is electrically connected to the circuit board 22 by coming into contact with the contact pin 22a provided on the circuit board 22.

When using such a mobile terminal, the user holds the device case 1 by grasping the grip portion 14 at the position where the battery lid 10 is located with one hand. That is, in order for the user to operate the key operation unit 5 with the thumb F1, the user covers the key operation unit 5 with the other fingers F2 to F5 extending from the side of the device case 1 to cover the back surface of the device case 1. The user grasps the grip portion 14 with one hand in a grasping mode that supports the grip portion 14.

At this time, the thumb F1 is arranged on the key operation portion 5 on the surface of the device case 1, and the crown portion of the raised portion 15 having a shape having a bulge between the index finger F2 and the middle finger F3 of the hand grasped by the user. 15a is arranged, and in this state, the pad of the index finger F2 is pressed against the first finger hooking area 17 in the raised portion 15 of the battery lid 10 located on the back surface side of the device case 1, and the other fingers F3 to F5. Each belly is arranged on the second finger rest area 18 of the raised portion 15.

In this state, in order for the user to operate the key operation unit 5 with the index finger F1, the user puts the index finger F1 on the key operation unit 5 and extends the device case 1 from the side of the device case 1 with the other fingers F2 to F5. The pad of the index finger F2 of the hand grasped by the user is pressed against the inclined surface of the first finger hook region 17 in the raised portion 15 of the battery lid 10 in a grasping mode that supports the back surface of the battery lid 10, and in this state, the first The finger hook area 17 is directed toward the lower side of the device case 1, that is, the hand side to be grasped by the user, and the index finger F2 of the grasping hand is attracted.

In this case, the belly of the index finger F2 is pressed against the inclined surface of the first finger hook region 17 in the raised portion 15 of the battery lid 10 and is pulled toward the lower side of the device case 1, that is, the hand side grasped by the user. Then, the index finger F2 is naturally bent and pressed against the first finger resting region 17 along the curve.

At this time, even if the index finger F2 of the hand grasped by the user is pressed against the first finger hook area 17 in a bent shape along the curve, the pad of the index finger F2 inserts the button of the first finger hook area 17. It does not go deep into the hole 21. Therefore, since the operation button 20b is not pushed by the pad of the index finger F2, the switch body 20a does not turn on.

Further, at this time, in order for the user to operate the key operation unit 5 with the thumb F1, the user covers the key operation unit 5 with the other fingers F2 to F5 extended from the side of the device case 1. Each belly of the other fingers F3 to F5 of the hand grasped by the user is pressed onto the second finger hook region 18 of the raised portion 15 in a grasping mode that supports the back surface of 1. In this state, the fingers F3 to F5 are arranged side by side in a naturally bent state along the curve of the second finger hook region 18.

As a result, the middle finger F3 to the little finger F5 are raised portion 15 in a state where the crown portion 15a of the raised portion 15 having a bulging shape is arranged between the index finger F2 and the middle finger F3 of the hand grasped by the user. It is arranged side by side in the second finger hook area 18 in a state of being naturally bent so as to wrap around the second finger hook area 18. Therefore, the fingers F3 to F5 are well arranged in a stable state along the curved surface of the second finger hook region 18. As a result, the user can surely and satisfactorily grasp the grip portion 14 of the device case 1 with one hand.

In this way, when the user grips 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 gently gentle from both side portions of the grip portion 14 toward the back surface side.
