Description of the invention: [Technical field to which the invention belongs] The present invention relates to a multi-directional input device mounted on, for example, a portable telephone or a portable audio device, which can perform a rotary operation and a pressing operation, and particularly relates to- A multi-directional input device that can be miniaturized without reducing operability. & [Prior art] In a portable telephone or the like, a multidirectional input device is known, that is, a rotary switch as a rotary operation type electric part and a tactile switch as a press operation type electric part are close to each other and separately The arrangement is such that a desired telephone number can be sequentially selected from a plurality of telephone numbers displayed on the liquid crystal display unit based on the first electrical signal output from the rotary switch, such as a mobile cursor, and based on the second electrical signal output from the rotary switch. Set the call mode to dial the selected phone number automatically. In addition, a multi-directional input device is disclosed in the following patent document ^, and the switch device is switched by a swing motion of the operating body and a movement in a radial direction intersecting with its swing locus. The device described in Patent Document 的, as shown in FIG. 8, an operating body 120 ′ having an arc-shaped operating end portion 120 a has a fulcrum axis 150 as a fulcrum and a neutral position shown in FIG. It can rotate freely in the counterclockwise direction and slide the operating body 120 on the fulcrum axis 15 to move in the radial direction (γ2 direction shown in the figure) from the neutral position as a starting point. In addition, the winding portion 14 of the torsion coil spring 140 is held by the operation body 120, and the arm portions 140b and 14c of the torsion coil spring 140 are supported by the base portion. The above-mentioned operation body 96749.doc 1242225 is always neutral. The common movable contact 128a and the movable contact 127a are connected to each other on the operating body 120. The base part is provided with the common fixed contacts i3 and 3 which are always in sliding contact with the common movable contact 128a. Switching fixed contacts 丨 丨 〇, i 11, 丨 12. If the operating body 120 rotates clockwise, the movable contact 127a contacts the switching fixed contact 110, and the switching fixed contact passes through the movable contact 127a and the public The movable contact 128a is electrically connected to the common fixed contact 113. In addition, if the operating body 12 is turned counterclockwise, the movable contact 127a is in contact with the fixed contact U1, and the fixed contact 111 is electrically connected to the common fixed contact 113. In addition, If the operating body 120 moves in the radial direction (not shown in the figure), the movable contact 127a is in contact with the fixed contact, and the fixed contact 112 and the common fixed contact 丨 3 are in conduction. Patent Document 1 · · JP 9 -274830 is shown in FIG. 8 In the input device ιο, if the rotation radius R of the operation end portion 120 is too small, hold the operation end portion 12 with a finger to make the rotation range narrow when swinging, and the operability is reduced. Therefore, the rotation radius must be reduced. The ruler is set to a certain length.

In this state, the support portion 4a provided on the operation body 4 is inserted into the bearing portion formed on the base portion 2A of the lower case 2 above. In addition, the base 4 of the operating body 4 is positioned in a gap formed between the aforementioned face 2C and the surface inside the upper case 3. In addition, the surface on the inner peripheral side of the operation end portion 4B is opposed to the front face of the lower case 2 96749.doc -15-1242225 2C. Therefore, the operating body 4 can swing freely around the support portion 乜 as a center in a clockwise (CW) direction and a counterclockwise (ccw) direction. In other words, the operating body 4 uses the clockwise (cw) direction and the counterclockwise (ccw) direction as the swing track, and the support portion 4a serves as the center of curvature of the swing track. On the other hand, the front ends of the pair of arm portions 6b and 6c protruding to the outside of the base portion 4A through the through grooves 4g of the operation body 4 are inserted into the recessed portions 2D and 2D of the lower case 2 and caught by the card. The engaging convex portions 2e and 2e are engaged. Moreover, in a state where the above-mentioned operating body 4 shown in FIG. 4A is installed in the lower housing 2, the pair of arm portions 6b and 6c of the twisted spiral bomb 6 are almost straight in the X direction (the angle Θ and 180 degrees ) To extend. Therefore, the torsion coil spring 6 is also in a natural state or a slightly contracted state in this state, and is in a state where it does not shake in the recessed portion 4b. The operation of the multi-directional input device 1 will be described below. (Neutral State) FIGS. 4A and 4B show a state where the operation body 4 is in a neutral position. In this neutral state, the protrusion 4B1 of the operation end portion 4B provided on the inner peripheral side middle portion faces the guide groove 2a at a position away from the guide groove formed in the middle of the front face 2C toward the outer periphery. 48 is in a state where it is not biased in either direction. The pair of arm portions 6b and 6c of the torsion coil spring 6 form a straight line and are parallel to the X axis. The support portion 4a provided on the operating body 4 is in contact with the inner surface of the circular arc portion of the bearing portion 2b formed in the inverted U-shape and provided on the lower housing 2 toward the γ1 side in the figure. status. 96749.doc -16- 1242225 In the above neutral state, the movable contact 5b3 provided on the other sliding arm 5b side of the above-mentioned sliding sheet 5 is in contact with the common fixed contact 14, and the movable contact 5b is provided on the one sliding arm 5a side. The contact 5a3 is located in the small space 2A1. Therefore, 'between the fixed contact 11 for rotation detection and the common fixed contact 14, between the fixed contact 12 for rotation detection and the common fixed contact 14, and between the fixed contact 13 for motion detection and the common fixed Each of the contacts 14 is set to the OFF state (high impedance state). Furthermore, "as shown in Fig. 7", the movable contact 5a3 of the sliding piece 5 is elastically crimped at the small space 2A1, and the movable contact 5b3 is elastically crimped to the common fixed contact ι4 (not shown in Fig. 7). Therefore, the operation body 4 is pushed in the direction shown in FIG. 21, and the contact portions 4i and 4i formed on the surface of the first frame portions 4d and 4d of the operation body 4 press the inner surface (surface on the Z2 side) of the upper case 3. As shown by the solid line in FIG. 7, in the neutral state, the uppermost portion 6 a1 on the Z1 side of the winding portion forming the torsion coil spring 6 is opposite to the convex portion provided on the upper case 3. Opposite the position on the Y1 side of the picture. (Pressing operation) As shown in Fig. 5A and Fig. 5B, if the operator presses "F1" and presses the operation end portion 4B in the direction of Y2 shown in the figure, the above The support part 移动 moves toward the end in the Y2 direction shown in the bearing portion hole, and the protrusion 4B1 enters the guide groove 2a, and the operating body 4 slides in the Y2 direction shown in the figure. At this time, as shown in FIG. 5B, the above The movable contact outside the other sliding arm of the sliding piece 5 slides on the common fixed contact 14, and the movable contact 5a3 which is one sliding arm moves from the base portion 28 forming the small space 2A1 to the detection. The fixed contact 13 is used. Therefore, the above-mentioned movement 96749.doc 17 I242225 detection fixed contact 13 and the common fixed contact 14 can be switched to the ON state (low impedance state) via the sliding sheet 5. In addition, at this time, as shown in FIG. 5A, the torsion coil spring 6 is also operated as described above. The working body 4 moves together in the direction of Y2 shown in the figure, and the front ends of the pair of arm portions 讣 and ^ are engaged by the engaging convex portions 2e and 2e. Therefore, the pair of arm portions 讣 and the heart elastically deform into a substantially V shape. That is, in the state shown in FIG. 5A, the elastic resetting force fl generated by the torsion spiral bomb 6 is applied to the operating body 4 in the direction of Y1 in the figure. Therefore, if the pressing force F1 is released, then The operating body 4 is reset to the neutral position shown in FIG. 4 by using the elastic resetting force of the torsion helical spring 6. Therefore, the fixed contact ^ 3 for the above-mentioned movement detection and the common fixed contact 14 can be reset. The second switching device is switched between ON and OFF states between the movable contact 5a3 and the above-mentioned fixed contact 13 for motion detection. In addition, as shown in FIG. 7 As shown, if the operating body 4 moves in the direction γ2 shown in the figure, the uppermost part 6 a1 on the zeta side of the illustration of the winding portion 6 a forming the torsion coil spring 6 reaches the position shown by the dotted line. At this time, the uppermost part 6al is set to the Y2 side in the figure. The convex portion 3a on the upper casing 3 can give the operator a click feeling. In addition, when the pressing force is released! ^, The operation body 4 moves toward ¥ 1 as shown in the figure, and it is possible on that day. Since the uppermost part 6a1 crosses the convex part 3a toward the side of the figure Υ1, it can also give the operator a snapping feeling. (Swinging operation in a clockwise direction) The following is shown in FIG. 6A and FIG. 6B As shown, if an operating force F2 is applied in a clockwise direction (cw direction) to the operation portion 4B, the operation body 96749.doc • 18-1242225 4 can be moved from the neutral position toward the support portion 4a. Cw direction swing. At this time, as shown in FIG. 6B, the movable contact 5b3 of the other sliding arm 讣 of the sliding sheet 5 slides on the common fixed contact 14, and the movable contact 5a3 of the one sliding arm & is formed from the small space 2A1 described above. The base part 2 is moved to the fixed contact 1 丨 for rotation detection. Thereby, the fixed contact 丨 丨 for motion detection and the common fixed contact 14 can be switched to the ON state (low impedance state) via the sliding sheet 5. In addition, at this time, as shown in FIG. 6A, on the magic side, the arm portion 6b of the torsion coil spring 6 is maintained in a state of being engaged above the engaging convex portion, and On the one hand, the arm portion 6c is pushed up by the latching portion 4h of the operation body * and separated from the engaging convex portion. Therefore, the pair of arm portions 6b and 6c are elastically deformed so that the included angle θ is 180 ° or less . In other words, in the state shown in FIG. 6A, the two arm portions 6 b and 6 c of the torsion coil spring 6 are changed into a substantially V-shape and contracted, and the buckling portion 牝 on the X2 side of the operating body 4 is contracted. The elastic resetting force f2 generated by the torsion coil spring 6 is applied in the direction of ccw shown in the figure. Therefore, when the clockwise operation force F2 is released, the operating body 4 is reset to the neutral position shown in FIG. 4 by the elastic resetting force f2 generated by the torsion coil spring 6. At the same time, the movable contact 5b3 of the slider 5 is returned to the small space 2A1. Therefore, the month b switches the fixed contact for the rotation detection and the common contact 14 to the OFF state again. That is, the first switching device for switching the ON state and the ON state of the switch is formed between the movable contact 5a3 and the fixed contact 11 for rotation detection. (Swing operation in the counterclockwise direction) 96749.doc -19-! 242225 Similarly, if an operation force F3 is applied in the counterclockwise direction (ccw direction) to the operation portion 4B, the operation body 4 can be supported by the operation. The central part is swung from the neutral position to the CCW direction from the neutral position (refer to the dotted line in FIG. 6 and FIG. 60). At this time, as shown in FIG. 6C, the movable contact 5b3 outside the other sliding arm of the sliding piece 5 is in the public The fixed contact 14 slides, and the one movable movable contact 5a3 is moved from the base portion 2A forming the small space 2A1 to the fixed contact 12 for rotation detection. Thus, the sliding contact 5 The fixed contact 12 for rotation detection and the common fixed contact 14 are switched to the ON state (low-impedance state). At this time, the buckle portion on the χι side of the operating body 4 is shown in the figure. The elastic resetting force f3 (not shown) generated by the torsion coil spring 6 is applied in the CW direction. Therefore, when the above-mentioned counterclockwise operating force F3 is released, the operating body 4 is caused to use the torsion coil spring. The above-mentioned elastic weight force f3 of 6 is reset The neutral position shown in Figure 4-8. At the same time, the movable contact 5b3 of the sliding sheet $ returns to the small space 2 magic, so the fixed contact 12 and the common contact 14 for the above-mentioned rotating $ test can be switched again. 〇 卯 state. That is, between the movable contact & 3 and the fixed contact for rotation detection, the above-mentioned} contact portion of the ON state and the FF state of the switch is formed. In the above-mentioned multi-directional input device !, as shown in FIG. 4B, the radius between the support portion buckle and the #work end portion 4B ensures that the operation t of the operating body 4 does not decrease the size R. Moreover, the torsion coil spring 6 and the above-mentioned switching devices are all provided on the side having the operating body 4 (the Y1 side in the figure) more than the supporting portion 4a. Therefore, it is not necessary to have an operation 96749 in a direction more than the supporting portion 乜. doc -20- 1242225 Arrange any component in the area on the opposite side of the body 4, and the minimum required size hl that can be used to form the lower case 2 etc. is sufficient. From this, 'the whole of the above-mentioned multi-directional input device The dimension h may be a ruler with a necessary minimum added to the above-mentioned radius R. Since the size of inch hi (h == R + hl), the overall size of the multidirectional input device 1 (especially the size in the Y direction shown in the figure) can be miniaturized. Furthermore, in the above-mentioned embodiment, it is a neutral resetting device. The use of a torsion coil spring has been described as an example. However, the present invention is not limited to this, and a leaf spring or the like that is substantially V-shaped in a natural state may be used. The movable contacts 5a3, 5b3w / bone moving piece 5, and a structure in which fixed contacts are provided on the base portion 2a of the lower casing 2 are not limited to this, and the present invention may also be adopted in the above-mentioned bases. The seat is provided with a sliding piece and a fixed contact provided on the operating body.
