Portable information processor
First Claim
1. A portable information processor comprising:
- first and second portions superposable in stacked form relative to each other;
a deformable member connecting said first and second portions so as to allow said first and second portions to be superposed in said stacked form;
a light-emitting device and a photodetector provided in one of said first and second portions;
a light reflection member, provided in either the other portion or said deformable member, for reflecting light emitted from said light-emitting device toward said photodetector when said first and second portions are disposed in a predetermined superposed state; and
a processing unit for determining, based on incidence of said emitted light on said photodetector, whether or not said first and second portions are in said superposed state, and for carrying out a predetermined process on a determination that said first and second portions are in said superposed state.

Abstract
A portable information processor includes a computer main body and a digitizer connected by a flexible hinge defined in a cover. The hinge allows the computer main body and the digitizer to assume different superposed states by means of a flexible separable portion of the cover. In the superposed state of the computer main body and the digitizer, arbitrariness in folding back the separable portion causes runout between the computer main body and the digitizer. In spite of this runout, the superposed state can be accurately detected by means of an optical sensor, including an infrared radiator and an infrared-ray detector, disposed in the computer main body. A flexible reflection member is fixed to a predetermined surface of the separable portion of the leather cover, while assuring a predetermined area. If the computer main body and the digitizer assume a superposed state, light emitted from the infrared radiator is reflected by the flexible reflection member and is incident on the infrared-ray detector.

11. A portable information processor comprising:
-
first and second portions superposable in stacked form relative to one another;
a deformable member connecting said first and second portions, deformable so as to allow said first and second portions to be superposed and to be separated in a predetermined range;
a supersonic wave transmitter provided in one of said first and second portions;
a supersonic wave receiver, provided in one of said first and second portions, for receiving supersonic waves, transmitted from said supersonic wave transmitter, and reflected by the other portion or deformable member when said first and second portions are disposed in a superposed state; and
a processing unit for determining, based on the reception of said supersonic waves at said supersonic wave receiver, whether or not said first and second portions are in said superposed state, and carrying out a predetermined process when judging said first and second portions to be in said superposed state.

12. A portable information processor comprising:
-
first and second portions which can be superposed in stacked form with each other;
a deformable member connecting said first and second portions, while allowing said first and second portions to be superposed and to be separated in a predetermined range by deforming;
a light-emitting device provided in one of said first and second portions;
a photodetector, provided in either the other portion or said deformable member, for receiving light emitted from said light-emitting device, when said first and second portions go to a predetermined superposed state; and
a processing unit for judging, based on incidence of light from said light-emitting device on said photodetector, whether or not said first and second portions are in said superposed state, and carrying out a predetermined process when judging said first and second portions to be in said superposed state.
