BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described with reference to the drawings. Note that the dimensions, materials, shapes, relative arrangements, and the like of the components in the illustrated example are not intended to limit the scope of the present invention, but are merely illustrative examples, unless otherwise specified.
[0022]
First, referring to FIG. 1, a portable information terminal apparatus shown (PDA), the user is a size capable of being held in the palm, the liquid crystal panel 12 on a front surface of the exterior case 11, with the touch panel 12a over substantially its entire surface There are arranged (the touch panel 12a, for example, is arranged on the surface of the liquid crystal panel 12). Furthermore, as will be described later, a control switch (hereinafter, referred to as a side controller) 13, an escape switch 14, a power on / off switch (hereinafter, referred to as a power switch) 15, and an insertion into which an external memory medium is inserted are inserted into the outer case 11. A slot 16, an external connection terminal 17 used for transmitting and receiving various data, and a storage unit 19 for storing a touch pen (stylus pen) 18 are provided.
[0023]
As shown in FIG. 1, the side controller 13, the escape switch 14, and the power switch 15 are arranged in a line on the side surface of the outer case 11. In the illustrated example, the side controller 13, the escape switch 14, And the power switch 15. The side controller 13 so as to outer casing 11 liquid crystal panel 12 comes in front, for example, when gripped by the left hand side controller 13 left thumb is placed in a position likely to be located.
[0024]
An outwardly extending protrusion 11 a is formed above the side controller 13, and a part of the side controller 13 is exposed on a side surface of the outer case 11. The side controller 11 is configured to be swingable (rotatable) within a predetermined range in a direction (vertical direction) indicated by a solid arrow A in the drawing, and a shaft (not shown) extending from the front (front) to the back of the outer case 11. ), And supported in a direction perpendicular to the shaft body (a direction inward from the side surface in the drawing) (solid arrow B). The pivot (swing) range is limited substantially in a single push-up or push down operation to the rotation (swinging) operable range by the left thumb. Then, on the exposed surface of the side controller 13, for example, protruding portions 13a of the waveform is formed.
[0025]
As described above, the side controller 13 is rotated (swinged) or pressed by the left thumb, for example. At this time, the left thumb touches the protrusion 13a. The side controller 13 is located at a predetermined position (hereinafter referred to as a reference position) when not operated, and when the left thumb is pushed upward from the reference position, the side controller 13 is moved by a predetermined rotation amount (swing amount).
