Abstract

The information terminal body may be designed to foldably pivot a pair of flat cases each having a display unit through a hinge which is equipped with a photographing optical system for the camera function unit of which optical axis of lens is perpendicular to an axial center of the hinge. The display units display information from communication channels and images taken in by the camera. The cases may have the display units such that the display units face outside in a folded state. At least one of the two display units may be a finder for photographers, while the other may be a finder for the subject persons. The terminal is equipped with a shutter button and a terminal operation button. The terminal operation button works also as a shutter button. The information terminal is also equipped with a viewfinder for the camera lens system.

Claims

1. A portable information terminal which comprises:

a camera unit;

a shutter button for said camera;

a viewfinder of which optical axis is parallel to that of lens of said camera; and

a display unit for displaying information from transmission channels or image taken in by said camera,

wherein said lens and said viewfinder on the front side of said portable information terminal are directed to a subject and said display unit is placed on the rear side.

2. The portable information terminal according to claim 1, wherein:

said viewfinder is retractable; and

said viewfinder is positioned at an upper corner of the information terminal, while said shutter button is positioned at the another upper corner.

3. A portable information terminal which comprises:

a camera unit;

a housing for said camera; and

a pair of flat cases which pivots through a hinge,

wherein;

each of said cases is equipped with a display unit for displaying information from transmission channels or image taken in by said camera;

said hinge is equipped with said housing;

an optical axis of lens of said camera is perpendicular to an axis of said hinge; and

said hinge has a structure in which said cases are pivoted by two shafts parallel to the axis of said housing; and

said display units face inside said information terminal body in a folded state and they face outside said information terminal in an unfolded state.

4. The portable information terminal according to claim 3, wherein one of said display units faces a subject and displays a mirror image of an image as taken in by said camera.

5. A portable information terminal according to claim 3, wherein said display units are positioned such that the cases are opposite to each other when said display units are folded, while they face the same side when said display units are unfolded at 180°

.

6. The portable information terminal according to claim 3, wherein said housing is rotated by 360°

so as to locate said display units inside or outside said information terminal in a folded state, while said housing is rotated so as to locate said display units on the same side in an unfolded state.
