Abstract: A mobile terminal 10 includes a fixing member 20 which fixes a plate shaped member 18 to a case 13 of a casing 12. The fixing member 20 is formed substantially in the shape of a frame including a first member 21 to a fifth member 25 extending along a first side surface 35 to a fourth side surface 38 of the case 13. The first member 21 to the fifth member 25 have sectional forms which are engaged with edge parts 18B of the plate shaped member 18 and engaged with stepped surfaces 46 of the case 13. The fixing member 20 is formed to be deformable so that a dimension L1 of a space between the fourth member 24 and the fifth member 25 may be increased or decreased.

Abstract: Provided is a handheld terminal device in which an excellent seal can be obtained without causing twisting, air bubbles, or gaps in double-sided tape. The handheld terminal device (100) has a water-resistant construction for a camera unit (113), a speaker unit (114), a charging terminal unit (116), a keypad (117), an antenna unit (118), a main display (121), and a sub-display (122). Said water-resistant construction comprises convex ribs having edge-shaped protrusions that press on water-resistant double-sided tape. For example, the sub-display (122) is provided with: a display unit (151) having a display opening (151a); a water-resistant wall (152) that is formed on the surface of the display unit (151) and has a convex rib (153); and water-resistant double-sided tape (154) that attaches the upper face of the water-resistant wall (152) having a convex rib (153) to the inner face of a sub-display exterior case (155).

Abstract: A foldable portable terminal apparatus includes: a first casing including an operation portion, and a second casing including a display portion, which are connected through a connection portion so as to allow the second casing to open and close with respect to the first casing in a first direction and a second direction different from the first direction. The portable terminal apparatus includes a slide sheet printed with a character or symbol for operation purpose. The slide sheet slides in association with opening and closing actions in the first direction and has a hole formed along a sliding direction thereof.

Abstract: Orientation of display of an operation portion can be changed according to a screen of a display portion in a portable terminal apparatus capable of opening and closing a second casing with respect to a first casing in a first direction and a second direction. A portable terminal apparatus includes a first casing 1 including an operation portion and a second casing 2 including a display portion which are connected through a connection portion 3. The connection portion 3 includes a first rotation shaft 9 capable of rotating the second casing 2 in a first direction and a second rotation shaft 10 capable of rotating the second casing 2 in a second direction perpendicular to the first direction. The first rotation shaft 9 includes a protrusion portion 12.

Abstract: A portable terminal in which, even when an impact caused by dropping or the like acts on an engaging portion of a second rotating member, it is possible to prevent a lock pin for fixing the second rotating member, and an engaging portion from being broken is provided. A second housing portion 56 in which a magnet 63 of a second engaging portion 46 is disposed attracts an engaging pin 45 formed by a magnetic material, by a magnetic force to project the engaging pin 45 from the surface 11A of a first case 11, and a second case 12 is caused to rotate about a second rotating axis 32, whereby a second projecting portion 52 is housed in the second housing portion 56 and the engaging pin 45 is locked. The second projecting portion 52 is rotatable about the axis of a first projecting portion 51.
