However, when a specific portable information terminal realizes a function different from the original purpose, it must be provided with operability corresponding to the function. Specifically, when used as a mobile phone, it is desired to have a four-direction input + 1 fixed input function and a 360-degree omnidirectional coordinate input function when used as a game machine. In order to reduce the size, it is desirable that the four-direction input + 1 confirmation input function and the coordinate input function can be realized by one key operation and that a reliable operation feeling at the time of operation can be obtained.

In this multi-directional switch 60, four outer peripheral contacts 6 are provided on the lower surface of the input operating portion 62 which is divided into four parts with the central contact 61 provided on the substrate P as the center.
3, 63, 63, 63 are provided, and an inverted bowl-shaped disc spring 64 for generating a click feeling at the time of operation is attached to each contact. Pressers 66a, 66b for pressing the apex portion 65 of the inverted bowl-shaped disc spring 64 are provided at four locations in the central portion of the lower surface and the outer peripheral portion of the lower surface of the input operation portion 62 opposed to the inverted bowl-shaped disc spring 64. Of these, the vertical stroke that can be switched by the central pressing element 66a is set shorter than the vertical stroke that can be switched by the other outer pressing elements 66b.

In this pointing device 70, an inverted bowl-shaped disc spring 72 is fixed on a contact point 71 provided on the substrate P, and is separated from directly above a vertex 73 of the inverted bowl-shaped disc spring 72. While having opposing curved resistance surfaces 74,
A dome-shaped elastic member 76 having a leg portion 75 attached to the substrate P is provided apart from the outer periphery of the inverted bowl-shaped disc spring 72. Voltages in two directions orthogonal to each other are supplied to the bending resistance surface 74 from electrodes (not shown) arranged at positions that divide the circumference in contact with the substrate P and the leg portions 75 into four.

An operation shaft 78 is provided at the center of the dome-shaped elastic member 76 so as to project upward from the casing 77. When the operation shaft 78 is pushed down, the bending resistance surface 74 causes the inverted bowl-shaped disc spring. The variable resistance or voltage of the pointing device 70 is supplied at the contact position of the apex portion 73 of 72. Therefore, when the operation shaft 78 is tilted to the substrate P side, the bending resistance surface 74 rolls on the upper surface of the inverted bowl-shaped disc spring 72, and the contact position between the bending resistance surface 74 and the inverted bowl-shaped disc spring 72 changes, thereby changing. The resistance or voltage changes, and the position data of the operating shaft 78 can be read from this change. When the operating shaft 78 is further pushed down, the dome-shaped elastic member 76 is further deformed downward, and the bending resistance surface 74 is changed to the inverted bowl-shaped disc spring 7.
The second apex portion 73 is brought into contact with the contact 71 on the substrate P, and the fluctuating resistance or voltage is supplied to the contact 71. At this time, since the apex portion 73 of the inverted bowl-shaped disc spring 72 is reversed, a so-called click feeling can be obtained.

However, in the conventional multi-directional switch 60 described above, due to the size of the inverted bowl-shaped disc spring 64 for generating a click feeling at the time of operation, the distance between the adjacent contacts is reduced. Therefore, the operation direction is limited to about four directions. If the distance between adjacent contacts is too narrow, a malfunction that the contact different from the intended one will operate,
Switching reliability cannot be obtained and it cannot be used.
