Further, in the multi-directional input device of the present embodiment, the gMR element 605 is used as the magnetic detecting element. Since the GMR element 6〇5 is used as the magnetic detecting element in this manner, for example, the amount of operation on the operating shaft 3 can be detected with a higher resolution than when the Hall element is used as the magnetic detecting element. Furthermore, the present invention is not limited to the above embodiment, and various modifications can be made. In the above-described embodiments, the size, shape, and the like shown in the drawings are not limited thereto, and can be appropriately changed within the range in which the effects of the present invention are exerted. Further, it can be carried out as appropriate without departing from the scope of the object of the present invention. For example, in the above-described embodiment, only the rotation detecting means 6a and 6b have H' for the rotational order detection of the i-th driving member 4 and the second driving member $, but the configuration of the rotation detecting means 并非 is not limited to Therefore, it can be changed as appropriate. For example, in addition to the function of the rotation of the driving member 5, the function of detecting the first driving member 4 and the first resetting of the operating shaft 3 to 131100.doc -18-200919517 may be added. Fig. 5 is an enlarged view of the rotation detecting mechanism when the multi-directional wheeling device 1 of the above embodiment is added with a function of resetting the operating shaft 3 to the initial position. When the function of resetting the operating shaft 3 to the initial position is added As shown in FIG. 5, for example, it is considered that the energizing member 6() 7 as the elastic member is disposed at a position closer to the body (10) than the holding member 6〇2, and the holding member 6〇2 is returned to the initial position. The location is done ^. In this case, the first driving member 4 (second driving member 5) coupled to the holder 6〇2 is returned to the initial position in accordance with the ability imparted to the holder 602. Thereby, the operation shaft 3 connected to the fourth moving member 4 (second driving member 5) is returned to the initial position. The energizing member 607 is formed of, for example, an elastic material such as phosphor bronze, and has a substantially rectangular flat plate portion 6〇7& which is provided in a substantially rectangular shape corresponding to the cover 603, and a circular opening portion is formed in a central portion of the flat plate portion 607a. 6 〇. Further, around the opening 607b, the pair of leaf spring portions 607c and 607d having a semicircular arc shape are formed. The leaf spring portion 607c is opened to the lower side shown in Fig. 5, and the leaf spring portion 607d is opened upward in the figure, and is coupled to the flat plate portion 607a by both end portions thereof. A convex protrusion 607e is formed on the side of the holder 6〇2 at the central portion of the shank portion 607c. On the other hand, an accommodating portion 602b in which the projections 6〇7e are accommodated is provided on the upper end portion of the holder 6〇2 shown in Fig. 5 . The accommodating portion 602b is provided at a position where the protruding portion 607e is accommodated in a state where the first driving member 4 (the second driving member 5) is not rotated. Further, a plurality of holes 607f are formed at positions corresponding to the projecting pieces 60A of the cover 603 at the vicinity of the corner portion of the energizing member 6?7. 131100.doc -19- 200919517 When the energizing member 607 is provided, when the first driving member 4 (second driving member 5) rotates in accordance with the skewing operation of the operating shaft 3, and the holding member 602 rotates, The protrusion 607e moves in response to the rotation of the holder 602. At this time, the holding member 602 is given the ability to return the holder 602 to the initial position of the leaf spring 607c. Therefore, when the operation shaft 3 is released from the deflection operation, the first drive member 4 returns to the initial position as the holder 602 returns to the initial position. Thereby, the second drive member y is returned to the first drive member 4 The operation shaft 3 of the (second drive member 5) is returned to the initial position. Thus, when the function of returning the operation shaft 3 to the initial position is added to the rotation detecting mechanism 6a (6b), the energizing member 6〇7 can be used. The holder 6〇2 is returned to the initial position, so that the third driving member 4 (second driving member 5) coupled thereto can be reset to the initial position, and the operating shaft 3 can be reset to the initial position. The energizing member 607 is disposed between the casing 2 and the rotation detecting mechanism 6a (6b), simplifies the configuration in the casing 2, and can reset the operating shaft 3 to the initial position.
