According to the first electric signal output from the rotary switch, for example, a cursor is moved, a dialectical number can be selected from a plurality of telephone numbers displayed on the liquid crystal display section. The selected telephone number is automatically dialed based on the second electric signal 'output from the rotary switch, for example, the call mode. In addition, in the following patent document, a multi-directional input device is disclosed, in which a switch device is switched by a swing motion of an operating body and a movement in a radial direction crossing its swing locus. As shown in FIG. 8, the device described in Patent Document 1 includes an operating body 120 ′ having an arc-shaped operating end coffee. The fulcrum axis 150 is used as a fulcrum, and the neutral position shown in FIG. 8 is used as a starting point in a clockwise direction. It can rotate freely in the counterclockwise direction, and by sliding the operating body m on the fulcrum axis 15o, it can move in the radial direction (the direction shown in Fig. 2) from the neutral position as a starting point. In addition: The twisted portion of the spiral spring meal 14G i4Ga is held by the operating body 12 (), and the torsion coil springs! The arms 140b and 140c of the 40 are supported by the base portion. The above-mentioned operating body ⑵ 96749.doc 200525569 always orders Apply force in the upright position. On the operating body 120, the common movable contact 128a and the movable contact 127a are electrically connected to each other. The base part is provided with the above-mentioned common fixed contact 113 which is always in sliding contact with the common fixed contact 113 and three switching fixed contacts 丨 i 〇, 1 丨 丨, 丨 i 2. When the right operating body 120 is rotated clockwise, the movable contact 12 is in contact with the switching fixed contact 110, and the switching fixed contact is conducted to the public fixed contact 113 via the movable contact 127 & and the common movable contact 128a. In addition, when the operating body 12 is rotated counterclockwise, the movable contact 127a contacts the fixed contact ^ 丨, and the fixed contact ill and the common fixed contact 113 are conducted. In addition, when the operating body 120 moves in the radial direction (downward direction shown in the figure), the movable contact 127a comes into contact with the fixed contact 112, and the fixed contact 112 and the common fixed contact 113 are conducted. Patent Document 1 · Japanese Patent Application Laid-Open No. 9-274830 In the input device 101 shown in FIG. 8, if the turning radius R of the operation end portion i20a is too small, the operation end portion 12a is held with a finger to make it. The turning target has a narrow circumference during swinging, which reduces the operability. Therefore, it is necessary to set the turning radius r to a certain length. However, the input device 101 is provided with a winding portion of the torsion coil spring 140 serving as a resetting device around the rotation center 0 (the center of the fulcrum shaft 15G) of the operating body 120. The torsion coil spring ⑽ The twisted portion 140a is subjected to torsional deformation around the rotation center 0 as a center. Therefore, in this input device 101, the winding portion 14 needs to be provided on the Y2 side (the side opposite to the installation side of the operation end portion 12a) than the imaginary line PP extending laterally through the rotation center 0. 〇3 The lower half locates the area of size H1. In addition, the movable contact 127a and each fixed contact u0, ^, 96749.doc 200525569 112 are arranged further downward than the lower end of the illustration of the above-mentioned operating body i2〇. Therefore, it is necessary to use it below the area of H1. The area is similar to the size of the contact. For this reason, the overall size 方向 in the γ direction of the input device 101 shown in the figure needs to be at least the size of the lower half H1 of the winding portion 14a and the fixed contact n0 ~ added to the rotation radius R. The size of U2 is larger than the size of H2 (Η-R + Η1 + H2). Therefore, it is difficult to miniaturize the entire size Η of the input device 101.
