Moreover, the first mounting base 5 is composed of a U-shaped member, and the orientation of the mounting hole 6 provided in one side portion of the U-shaped member can be adjusted by the degree of folding and the degree of folding elasticity. The mounting angle of the rotating shaft portion 8 that penetrates and engages with the mounting hole 6 can be appropriately set so that the second member 4 can be opened and closed along the overlapping surface from the state where the second member 4 is superimposed on the first member 2. Easy to do.
[0015]
Further, since the first mounting base 5 is formed of a U-shaped member and has a folded structure, a load is applied to the rotating shaft portion 8 engaged with the mounting hole 6 of the first mounting base 5. Even if added, the pressure can be absorbed, and a smooth rotation operation can be performed at all times, and the durability is greatly improved.
[0016]
Therefore, for example, if the first member 2 is the main body portion 2 provided with the operation portion 1 and the second member 4 is the overlapping portion 4 provided with the display portion 3, the end devices are overlapped and connected by the hinge device H. By doing so, the overlapping portion 4 can be connected to the main body portion 2 so as to be rotatable in a substantially horizontal direction. When the operation portion 1 is not operated, the main body portion 2 In this compacted polymerization state, the display unit 3 is disposed on the upper surface side of the polymerization unit 4, so that the display unit 3 can be operated even if the operation unit 1 cannot be operated. If the display unit 3 can be seen and the display unit 3 is configured to function, for example, a date or calendar set in advance by the operation unit 1 can be displayed, or a data communication display (for example, a mobile phone can be displayed). If or to perform the display, etc.), a display unit 3 enables various uses for visible, or spread intended use, improved functionality, very convenient and makes practical (commercial value) is increased.

In addition, when operating the operation unit 1, the operation unit 1 is rotated by approximately 180 degrees in the substantially horizontal direction instead of rotating the overlapping unit 4 to expose the operation unit 1. Part 1 can be exposed.
[0018]
Therefore, even if the display unit 3 is provided on the upper surface side which is the exposed side when the operation unit 1 is concealed by the superimposing unit 4 as described above, the operation is performed by horizontally rotating the superimposing unit 4 even if the display unit 3 is enhanced. Since the unit 1 can be exposed, the display unit 3 remains exposed even when the operation unit 1 is exposed, and the conventional use in which the operation unit 1 is operated and displayed on the display unit 3 is also possible.
[0019]
In addition, since the operation unit 1 can be exposed by a horizontal pushing operation for horizontal rotation instead of up-and-down rotation, the opening operation can be easily performed and handled as compared with the conventional up-and-down rotation operation.
[0020]
Further, the rotation shaft portion 8 of the hinge device H is configured to penetrate through the mounting hole 6 provided in the first mounting base 5 as described above, and the first mounting base 5 is folded U. Since the mounting hole 6 is provided on one side of the folded portion and the rotation shaft portion 8 is set so as to penetrate through at a predetermined angle, the axial direction of the rotation shaft portion 8 can be easily set. It can be set, and even if there is an error in the orientation of the rotating shaft part during installation, it can be absorbed and attached, and even if a load is applied to the rotating shaft part, it will be absorbed and compressed. An electronic device that can be opened and closed horizontally is easily realized, easy to assemble, and can be rotated smoothly at all times. It is a revolutionary hinge device with excellent durability and a portable device using this hinge device. Electronic devices such as telephones and mobile phones.
