Portable terminal

1. A portable terminal comprising:

a casing;

a circuit board housed in the casing;

a display device arranged parallel to the circuit board in the casing and exposed on an outside of the casing;

a fixing portion which fixes the circuit board to the casing to allow the circuit board to move within a given range along a surface direction of the circuit board;

a battery housing portion provided at a position in the casing located along a thickness direction of the circuit board;

a battery pack housed in the battery housing portion through a battery opening provided in the casing;

a board-side connecting portion provided at the circuit board;

a battery-side connecting portion provided at the battery pack and connected to the board-side connecting portion; and

a restraining member which restrains a movement of the battery pack with respect to the circuit board along a surface direction of the circuit board.

2. The portable terminal according to claim 1 , further comprising:

a chassis which holds the circuit board,

wherein the restraining member is fixed to the chassis.

3. The portable terminal according to claim 2 ,

wherein the chassis comprises a first surface and a second surface opposite to the first surface, the first surface being closer to the battery pack than the second surface,

wherein said portable terminal further comprises:

a board fixing screw which is screwed to the chassis and which fixes the circuit board to the first surface of the chassis; and

a restraining member fixing screw which is screwed to the chassis and which fixes the restraining member to the first surface of the chassis,

wherein the display device is arranged on the second surface of the chassis, and

wherein a tip end of one of the board fixing screw and the restraining member fixing screw does not contact the display device.

4. The portable terminal according to claim 3 , further comprising:

a fixing buffer member interposed between the circuit board and the chassis,

wherein the fixing buffer member is penetrated by the board fixing screw.

5. The portable terminal according to claim 1 , further comprising:

a chassis which holds the circuit board; and

a chassis buffer member which is provided at a plane angle portion and which contacts an inner surface of the casing.

6. The portable terminal according to claim 1 ,

wherein the casing is formed by two-color molding so as to expose a hard resin on an inner surface of the casing and so as to expose a soft resin to an outer surface of the casing, and

wherein a display device buffer member is interposed between an end surface of the display device and the inner surface of the casing.
