Abstract

PROBLEM TO BE SOLVED: To provide a folding portable telephone set which can also be used as a mirror, etc., besides as a telephone set. SOLUTION: A signal changeover switch 19 is arranged on a side of the folding telephone set 1. The cutoff/pass of an input signal from a display controlling part 18 to a mirror reflection type liquid crystal 20 is controlled in such a manner that a user performs an on/off operation of the switch 19. When the switch 19 is turned off, the input signal from the part 18 to the liquid crystal 20 is interrupted to make the liquid crystal 20 usable as the use of a mirror. When the switch 19 is turned on, the input signal from the part 18 to the liquid crystal 20 is made to pass as it is, so a dial number, etc., when transmission and reception are performed, is displayed on the liquid crystal 20.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable portable telephone, and more particularly to a foldable portable telephone whose housing can be folded.

[0002]

2. Description of the Related Art Conventionally, a portable telephone is provided with a liquid crystal display for displaying a telephone number of a caller and a callee, a name of a callee, and the like. It is arranged on the same plane as the operation key unit for inputting.

However, when the operation key section is exposed together with the liquid crystal screen, the operation key section may be depressed when the mobile phone is stored in a pocket, a bag, or the like. The operation key portion is locked, or the operation key portion is covered with an openable / closable flip, or the housing itself is configured to be foldable.

[0004]

In the above-mentioned conventional portable telephone, when the housing itself is configured to be foldable in order to protect the operation key portion, in addition to the protection of the operation key portion, a liquid crystal screen is provided. Can be made the same size as the operation key section. However, the liquid crystal screen can only display characters, figures, and the like.

It is an object of the present invention to solve the above-mentioned problems and to provide a foldable portable telephone which can be used not only as a telephone but also as a mirror.

[0006]

A foldable portable telephone according to the present invention is folded with at least a display screen for displaying characters and codes and an operation key unit for inputting the characters and codes facing each other. A foldable mobile phone including a housing, comprising a display element forming the display screen and serving as a mirror-like reflective surface when the characters and codes are not displayed.

Another foldable portable telephone according to the present invention includes a housing in which at least a display screen for displaying characters and codes and an operation key unit for inputting the characters and codes are folded to face each other. A foldable mobile phone in which power is supplied only to necessary parts when the housing is closed, a detecting unit that detects whether the housing is closed, and a detecting unit that detects whether the housing is closed. Control means for controlling the supply of the power according to the detection result, a display element constituting the display screen and serving as a mirror-like reflective surface when the characters and codes are not displayed, and from the detection means to the control means. And a switch member for switching between blocking and passing of the detection signal according to an external instruction.

That is, the folding type portable telephone of the present invention uses a specular reflection type liquid crystal as a liquid crystal screen, and makes it possible to use the specular reflection type liquid crystal surface as a mirror when the portable telephone function is not used.

More specifically, the foldable portable telephone according to the present invention has a display portion composed of a specular reflection type liquid crystal and a liquid crystal frame, and the specular reflection type liquid crystal displays a liquid crystal when an input signal is present. In the case where there is no input signal, like a mirror, it is a liquid crystal capable of projecting a face or an object facing the reflection surface. The liquid crystal frame uses a reflective element capable of projecting a face or an object facing the reflective surface, similarly to the specular reflective liquid crystal.

Turning on / off an input signal to the specular reflection type liquid crystal
A switch for switching off is arranged on the side surface or the front surface of the mobile phone, and the use can be switched by this switch.
