2. Description of the Related Art In recent years, mobile phones, which have become widespread in Japan, have become smaller and lighter each year, and have become easier to carry on a daily basis. Various functions such as connection and e-mail are added, and various usages are possible, and the market has been significantly expanded from adults to children, and with the spread of such portable terminal devices, similar A variety of portable devices having an image display unit, such as portable game machines, digital cameras, remote controllers, portable GPS, portable learning machines, electronic dictionaries, portable translators, electronic books, etc., utilizing technology are successively developed and sold. While these portable devices are becoming smaller and lighter every day, technological innovations are remarkable toward colorization, higher image quality and larger screen of the image display, and many people are busy with their choice. Rather, has fallen to the situation are forced to considerable difficulty in mastering the instrument.

A portable device, particularly a portable telephone, which forms the center of the device, must have a shape suitable for a handset in addition to its form. In addition to the mainstream that the operation parts are arranged and formed respectively, the shape of the image display part is also vertically long and the width is relatively narrow, and it is often the case that it is set vertically, so that it is not necessarily visible with both eyes Because it is not suitable and the displayed characters and images are fine, it is considered to be one of the factors that cause eyestrain for modern people who often face displays and small displays all day. However, similar to this mobile phone, even in the case of other mobile devices, the enlargement of the image display unit is contrary to the reduction in size and weight of the main body. To satisfy the needs that has become a very difficult task.

In order to eliminate the inconvenience caused by the image display unit which must accompany the miniaturization of the main body, for example, a pair of portable telephone bodies disclosed in Japanese Patent Application Laid-Open No. 2000-174865 for holding the main body from the front and back sides. The enlarged display device of the mobile phone, in which the convex lens can be manually attached to the image display unit as needed by manually attaching the convex lens by the holder described in JP-A-11-133234. A transparent hologram for a display window formed so that a transparent hologram having a lens-like optical function can be attached on the image display unit has been developed and proposed, but in the former case,
The convex lens is rotatably moved between the front surface and the back surface of the mobile phone body along a pair of holders, and it is difficult to perform the operation with one hand, and in addition to providing an angle adjuster. Also, there is a problem that it is difficult to hold the convex lens parallel to the image display unit and obtain an image without distortion at that position, and in the latter case, the transparent hologram is placed at a predetermined height on the image display unit. Since the technology for holding the transparent hologram is not disclosed, it is considered that the transparent hologram is directly adhered to the image display unit. However, there was a limit to this, and it was impossible to avoid the drawback of not being able to achieve a sufficient purpose.

In the present invention, as described above, the portable device itself has to give priority to the reduction in size and weight of the main body. Therefore, the size of the image display unit is naturally limited, and the portable device itself is not necessarily used. Not everyone is satisfied, and everyone has noticed that it's extremely hard to use, especially for users with poor eyesight or eye strain, but so far especially for that Questioned that the situation was being left without effective measures being taken, and from the determination that one of the users who felt the same inconvenience could not solve this problem, quickly We started development and research and repeated trial and error over a long period of time and many prototypes and experiments.As a result, this time, we finally expanded the portable device display unit with a new structure.
