Further, the spring body 57 is individually crimped and fixed to the other blocks 34 and 36 by the crimping fixing portions 34B and 36B shown in FIG.

  Reference numeral 41 denotes a frame made of a metal plate formed in a square cylindrical shape. The frame body 41 is provided with three holding holes 43 arranged side by side at equal intervals on one side surface portion 42 that is parallel to the longitudinal direction of the belt 31 (see FIG. 3), and the other side surface portion. Similarly, the guide holes 45 are provided at the three positions 44 in opposition to the individual holding holes 43 (see FIG. 3). The guide hole 45 has a substantially rectangular shape portion extending downward with a constant width. The holding hole 43 and the guide hole 45 are provided so that the blocks 34 to 36 with the spring body 57 constituting the holding base 33 can be tilted with respect to the frame body 41.

  That is, as shown in FIG. 7, one leg 34 </ b> A (35 </ b> A, 36 </ b> A) side of the block 34 (35, 36) has a positioning protrusion 37 provided on the outer surface thereof and a spring disposed so as to overlap therewith. One end side of the body 57 is inserted and engaged with the holding hole 43 of the side surface portion 42 with a slight gap in the vertical direction (corresponding to the horizontal direction in FIG. 7). A hook portion 58 that is bent downward is formed on one end side of the spring body 57. As can be seen from FIG. 2, the hook portion 58 has an inner surface that contacts the outer surface of the side surface portion 42. They are arranged in contact with each other.

  On the other leg 34A (35A, 36A) side of the block 34 (35, 36), as shown in FIG. 8, a guide projection 38 provided in the vicinity of the center height position of the outer surface is provided as a guide hole. 45 is inserted and arranged. In this state, the space of the guide hole 45 extends below the guide protrusion 38 (corresponding to the right in FIG. 8), and the guide protrusion 38 can move downward within the space. It has become. In addition, as for each block 34-36 distribute | arranged to the frame 41 as mentioned above, the adjacent blocks contact | abut in the arrangement | positioning state.

The part 34A (35A, 36A) side is configured to be capable of tilting downward.

  Further, in the arrangement state, the spring body 57 fixed to each block 34 (35, 36) also has one end side corresponding to one side portion 42 side at the lower surface of the positioning projection 37 and the lower end portion of the holding hole 43. By being sandwiched, it becomes a root portion in a fixed state, and the other end side is in a cantilever form that moves downward in accordance with the inclination operation of each block 34 (35, 36). Note that lower projections are provided on the other end side of the spring body 57 so as to correspond to a press switch 71 described later.

  Further, as shown in FIGS. 3 and 9, a bar-shaped magnet installation location 34C is further provided on the outer surface of the block 34 on the one leg 34A side, and a bar-shaped magnet 53 made of a permanent magnet is arranged there. Has been. The rod-shaped magnet 53 corresponds to the second magnet of the claims, and is arranged in such a manner that one pole is horizontally adjacent to the peripheral surface of the ring magnet 51.

  The rod-shaped magnet 53 affects the rotation state of the first rotating shaft 21 by the attractive repulsion force of the magnetic force with the ring magnet 51 when the first rotating shaft 21 rotates, and the influence causes the belt 31 to pass through the belt 31. It is for generating a click that is arranged to be transmitted to the finger to be operated. As will be described in detail later, a first plate member 54 through which magnetism is passed is disposed on the bar-shaped magnet 53 so as to overlap therewith, and the lower surface of the first plate member 54 covering the lower surface side of the bar-shaped magnet 53 is disposed at the position where the bar-shaped magnet is installed. Adhesive fixed to 34C. And the frame 41 part according to the arrangement position of the rod-shaped magnet 53 is made into the shape notched by upper opening. This is to eliminate interference between the bar-shaped magnet 53 and the corresponding frame body 41 during operation.

  The frame body 41 in which the respective parts are combined as described above is coupled to the hollow frame-shaped case 60 by, for example, locking the attachment portion 41A with a screw (not shown).

  On the other hand, reference numeral 61 denotes a wiring board disposed below the frame body 41. On the upper surface thereof, as shown in FIG. 3 and the like, three push-type switches 71 are disposed according to the position of the lower protrusion of the spring body 57. Further, two magnetic detection elements 75 are arranged corresponding to the lower position of the ring magnet 51. As shown in FIG. 3, if the case 60 and the wiring board 61 are provided with a shape portion having concavities and convexities that engage with each other, it is easy to align the above-mentioned parts only by combining them. preferable. Further, as a means for joining the wiring board 61 to the case 60, it may be joined by screws 80 or the like, but the method is not particularly limited. Further, the case 60 may be eliminated, and the frame body and the wiring board may be combined and combined with each other, and may be attached to the device housing via the mounting portion 41A.

  The three push-type switches 71 are arranged in a line at an internal position along the other side surface portion 44 of the frame body 41.

  The individual configuration of the push-type switch 71 is omitted in FIG. 2, but a thin metal plate that connects and separates the plurality of fixed contacts 62 (see FIG. 3) disposed on the wiring board 61 and the fixed contacts 62. A dome-shaped movable contact 63 made of a material, an adhesive is formed on the lower surface, and a flexible insulating sheet 64 for covering and positioning the dome-shaped movable contact 63 to be mounted on the wiring board 61. It is comprised from the operation protrusion 65 made. In other words, in the configuration, the dome-shaped movable contact 63 is held by the adhesive formed on the lower surface of the insulating sheet 64, and the surrounding adhesive part is adhered on the wiring board 61 to press the switch 71. Is used.

  When the operation projection 65 is pushed down, the push-type switch 71 having this configuration applies a push-down force to the dome-shaped movable contact 65 from above via the insulating sheet 64, and when the force exceeds a predetermined magnitude, the dome-shaped movable contact 63 The center part is reversed and the fixed contact 62 is made conductive by the contact of the lower surface thereof. This is preferable because the switch operation stroke is relatively short and a thin structure can be obtained that provides a modest feel during operation. It should be noted that another switch configuration may be mounted, or a single switch completed product may be mounted and arranged.

  Further, as shown in FIG. 2, a lower protrusion formed on the movable side of the spring body 57 described above is in contact with the operation protrusion 65 of each push-type switch 71.

  On the other hand, the arrangement positions of the two magnetic detection elements 75 arranged on the wiring board 61 so as to correspond to the ring magnet 51 are set so that a pulse signal output at the time of magnetic detection has a predetermined phase difference. .

  And between the ring magnet 51 and the magnetic detection element 75, as shown in FIG.3 and FIG.9, the 2nd board | plate material 76 which lets magnetism pass independently for every magnetic detection element 75 is distribute | arranged. The mounting method is not particularly limited, but it is preferable that the mounting is performed by attaching the magnetic detection element 75 on the magnetic detection element 75.

  The second plate member 76 is arranged to collect the magnetic flux from the ring magnet 51 positioned above the second plate member 76 and guide it to the magnetic detection element 75. As the material of the second plate member 76, for example, a magnetic material such as permalloy that easily transmits magnetic flux is preferably used, and the second plate member 76 allows the magnetic flux to act strongly on the magnetic detection element 75.

  On the other hand, the rod-shaped magnet 53 arranged for generating the click is provided with the first plate material 54 that allows magnetism to pass through the lower surface side that is the magnetic detection element 75 side as described above.

  The first plate 54 is arranged to prevent the magnetic flux from the bar-shaped magnet 53 from being detected by the magnetic detection element 75, and the path of the magnetic flux from the bar-shaped magnet 53 on the lower side is as follows. It mainly plays a role of looping through the first plate 54. As a result, the magnetic detection element 75 disposed below the first plate 54 is hardly affected by the magnetic flux of the bar magnet 53. As the first plate material 54, it is preferable to select and use a material that passes magnetism but is hard to be magnetized.

  The wiring patterns connected to the pressing switch 71 and the magnetic detection element 75 are routed on the wiring board 61 as shown in FIG. 3, and these patterns are led out from the wiring board 61 through terminals and the like. ing.

  The rotary operation type component according to this embodiment is configured as described above, and is mounted on a device to be used with at least the entire upper portion of the belt 31 exposed to the outside.

  Next, the operation of the rotary operation type component according to the embodiment will be described.

  First, the belt 31 is rotated by translating it in the tension direction using the belly of the finger on the upper part of the belt 31 exposed. As shown in each drawing, if a protrusion is provided on the outer surface of the belt 31, the belt 31 can be operated satisfactorily without finger slipping when the belt 31 is rotated. When the finger is moved in parallel, a downward pressing force is applied to the belt 31 below. However, if the holding base 33 is arranged in the belt 31, the belt 31 is not greatly bent downward. Rotational operability is good.

  The first and second rotary shafts 21 and 22 and the auxiliary roller 25 rotate in synchronization with the rotation of the belt 31, and the ring magnet 51 fixed to the first rotary shaft 21 also rotates synchronously. According to the rotational movement of the ring magnet 51, the operation in which the N pole and the S pole of the ring magnet 51 alternately approach on the two magnetic detection elements 75 is repeated. Then, the magnetic flux from the ring magnet 51 is guided downward through the respective second plate members 76 that allow magnetism to act on the two magnetic detection elements 75, and accordingly, a predetermined phase difference is generated from the two magnetic detection elements 75. A pulse signal having Based on the signal, the rotation direction and the rotation amount of the belt 31 can be detected by a control unit (not shown) of the device. The reason why the second plate member 76 is arranged independently for each magnetic detection element 75 is to eliminate mutual interference.

  Then, according to the rotational movement of the ring magnet 51, the N pole and S pole of the ring magnet 51 are repeatedly brought close to the rod magnet 53. When the different poles come close to each other, an attractive force is generated, and the same poles are A repulsive force is generated when approaching. The suction force and the repulsive force affect the rotation state of the first rotating shaft 21, and this is felt as a click feeling to the finger operating via the belt 31. In the non-operating state, the ring magnet 51 and the bar magnet 53 are maintained in an attracted state, so that unnecessary rotation of the belt 31 can be prevented.

  And the thing of the said structure used as the above operation states can perform rotation operation more efficiently than a conventional thing. That is, in the thing of the said structure, since the belt 31 can be horizontally moved within the range along the longitudinal direction where the belt 31 between the 1st and 2nd rotating shafts 21 and 22 was stretched, the belt 31 can be rotated, This is because a large amount of movement can be secured by a single operation.

  Moreover, since the product thickness in the vertical direction is mainly determined by the diameters of the first and second rotating shafts 21 and 22 and the thickness of the belt 31, the thickness is thin and easy to use, hardly affecting the operation distance. Can be.

  In order to smooth the rotation of the belt 31 during the rotation operation, the holding base 33 is provided with a linear uneven portion 33A along the longitudinal direction in which the belt 31 is stretched (FIGS. 2 and 5). Or a linear uneven portion thereof is provided on the inner surface of the belt 31 to reduce friction between them. In addition, when providing the linear uneven part 33A in the holding stand 33, it is important to provide the linear uneven part 33A on the upper surface side of the holding base 33 that is likely to be in contact with the rotating operation. Furthermore, it is preferable that the inner surface of the belt 31 is subjected to a textured process, or a combination thereof is used to obtain a synergistic effect.

  Next, when the belt 31 is pushed down from above the belt 31 at the center position, the central block 35 of the holding base 33 is pushed via the upper belt 31, and the block 35 is connected to the other side surface of the frame body 41. The part 44 side is tilted down. With this tilting operation, the position of the movable side of the spring body 57 is also lowered, and as shown in FIG. 10, the corresponding operation projection 65 is pushed down by the lower projection of the spring body 57, and the switching of the corresponding push-type switch 71 is performed. Made. At this time, the blocks 34 and 36 at both ends are not tilted and maintained at their original positions, and the state of the press switch 71 corresponding to them remains unchanged. In FIG. 10, the belt 31 is not shown for easy understanding of the position of each block.

  When the pressing force is removed, the dome-shaped movable contact 63 of the push-type switch 71 self-restores to the original upward convex dome shape and returns to the switch OFF state, and the spring body 57 is pushed up, and the cantilever spring The restoring force of the body 57 is also applied, and the central block 35 returns to the normal state shown in FIG.

  On the other hand, when the vicinity of the end position in the longitudinal direction where the belt 31 is stretched is pushed down, the block 34 (or 36) located on the end side of the holding base 33 is similarly tilted, and the spring body 57 is movable. The corresponding pressing type switch 71 is switched on the side. At this time, the block that has not been operated does not move, and the state of the push-type switch 71 is not switched accordingly. When the pressing force is removed, the corresponding pressing switch 71 returns to the original switch OFF state, and the restoring force of the spring body 57 is also applied to return the block 34 (or 36) to the original state.

  When the belt 31 is pushed down, the belt 31 is partially twisted. In any case during the pushing operation, the ring magnet 51 and the bar magnet 53 are attracted by different polarities, i.e. Since the stopped state of the one rotating shaft 21 is maintained, there is no problem. The configuration in which the ring magnet 51 and the bar magnet 53 are mounted on the same block 34 is particularly preferable.

  As described above, the rotary operation-type component can be realized as a thin product having a large operation amount during the rotary operation. Moreover, it can also be configured such that a switch operation disposed below the belt 31 can be performed by a pressing operation from above the belt 31. Further, the configuration in which the three push-type switches 71 described above can be individually operated can be applied to various uses as the number of devices that require a plurality of function selections increases.

  Note that the number of the push-type switches 71 is not limited to three. For example, the number of the push-type switches 71 may be one as in the prior art or may be two. Further, three or more push-type switches 71 may be arranged, and further, the push-type switch 71 may not be provided, and the structure may be used with only the rotating component part.

  As described above, the rotary operation type component according to the present invention can be configured to be thin so that the operation amount at the time of the rotation operation can be increased by one finger movement operation. Therefore, the items displayed on the display unit of the device can be scrolled. It is suitable for various electronic devices that are selected and operated, especially portable devices.
