Background art

In recent years, the widespread use of mobile phones has been remarkable, and the number of functions and the reduction in size and weight are increasing year by year, and the purpose of use is also diverse. Initially, voice communication was mainly used. It is used for image communication using photos, moving pictures, etc., such as communication, television broadcasting, and videophone.

And the functions of mobile phones are also changing according to the purpose of use due to the adoption of various media. Therefore, the display screen that was used primarily to display the other party's phone number etc. will be used for text communication and image communication, and as a result, the display screen will necessarily be upsized. Became.

Therefore, a portable telephone in which the display unit and the operation unit are separately provided to increase the size of the display screen is disclosed, for example, in Japanese Patent Application Laid-Open Nos. 6-37, 7-9, and 9- 1 2 7 7 3 4 Patent Document 2 and JP-A-2001-186626. These mobile phones are, as shown in FIG. 13, a telephone main body 1 having an inner side 13 provided with an operation unit 1 1 including an operation button and a mouthpiece 12 and a display screen 2 1 consisting of a liquid crystal display. The lid body 2 having the inner side surface 23 provided with the ring 2 and the reception ring 2 2 is hinged so as to be openable and closable by the hinge 3 in a state where the both side surfaces 1 3 and 2 3 face each other. It is a foldable mobile phone. This folding mobile phone is folded at the time of non-use such as charging and standby to make it a compact shape, At the time of operation etc., it is used in a state where the lid 2 is spread at a wide angle with the hinge 3 as a fulcrum to expose both inner side surfaces 1 3 and 2 3.

However, since the conventional portable telephone operates the operation unit 11 quickly at the time of operation, with the lid 2 open, the telephone main body 1 is held with one hand and the thumb operates the operation unit 11 composed of operation buttons There is a need to. Therefore, the width of the main body 1 of the telephone is limited, the cover 2 disposed opposite to the main body 1 also has the same width, and the width of the display screen provided on the inner side surface 23 of the cover 2 is also restricted. As a result, it is necessary to form a large size, in order to form a long in the vertical direction.

Therefore, for document communication such as e-mail, there is a problem that even if it is the same sentence, the number of lines increases, it is difficult to display as a series of sentences, and it is difficult to read when reading and reading. Since the image to be displayed is set to be wide in many cases such as the display device of a personal computer, a television, a movie, etc., the effective display area of the display screen is limited to the length in the horizontal direction. It is impossible to expect the effect of enlarging the display screen to such an extent that it is enlarged in the vertical direction only by forming an area.

On the other hand, when using a mobile phone having the above image communication function also for voice communication, in order to secure a good call, the earpiece corresponds to the position of the ear and corresponds to the position of the mouth. The mouthpieces must be placed close to each other at the same time, and an appropriate distance corresponding to the position is required between the two positions. Is almost common.

In addition, when operating the mobile phone, usually hold with one hand and operate with the holding hand, but in such a case, the mobile phone tends to be inclined to the user's line of sight, so push button and placement These characters are also prone to tilt, making it difficult for the operator to see and operate in many cases.

Therefore, it goes without saying that good voice communication can be performed, and it is possible to display an image such as an e-mail or a moving picture on a large horizontal display screen, and it is easy to operate. Development of mobile phones was strongly desired.
