Description

  The present invention relates to a slide operation device such as a fader device used to set a parameter such as a volume by moving a moving body in a box by manual operation of an operator.

  Conventionally, a slide operation device such as a fader device mounted on a mixer or the like is known. The slide operation device is generally configured such that the moving body moves in the box. For example, the moving body can be moved by a manual operation while holding the operation element fixed to the moving body. Then, the position of the moving moving body is detected, and various parameters such as volume are set based on the position.

  In general, the movable body is slidably engaged with a round bar-shaped movable guide provided in the box body along the longitudinal direction of the box body, so that the movable body is guided by the movable guide and moves in the longitudinal direction of the box body. Configured to be possible.

There is also known a slide operation device that can adjust sliding resistance when moving a moving body (Patent Document 1 below). In this device, the frictional force at the time of sliding can be adjusted by pinching the moving guide with a U-shaped spring and appropriately setting the pinching force with a screw.
Japanese Patent Laid-Open No. 2002-8907 JP 2006-49302 A

  However, in the above-mentioned Patent Document 1, there is a problem that a U-shaped spring and screw are required for generating friction, and the configuration of the friction generating mechanism is complicated. Further, the U-shaped spring has to be disposed so as to sandwich the movement guide and a screw must be attached, and there is a problem that it is not easy to assemble the friction generating mechanism.

  Particularly, in recent years, there has been known a technique that uses a non-contact type detection device such as a magnetic type instead of a brush or the like for detecting the position of a moving body (Patent Document 2). In this type of device, the sliding resistance between the brush and resistor for position detection cannot be used for sliding resistance, so the moving body can move freely, depending on the mounting angle of the device. There is a risk of unintentional movement, such as free fall. For this reason, it is important to provide a friction generating mechanism as described above so that the sliding resistance in the moving stroke of the moving body is appropriate.

  The present invention has been made to solve the above-described problems of the prior art, and an object of the present invention is to prevent the moving body from unintentionally moving in the box while being easy to assemble and having a simple configuration. An object of the present invention is to provide a slide operation device that can perform the above operation.

  To achieve the above object, a slide operating device according to claim 1 of the present invention includes a box (10) and a movable body (70) that is held in the box so as to be movable along the longitudinal direction of the box. An operating operator (80) fixedly provided on the movable body, a leaf spring (61) provided with latched portions (63) at both ends, and the latched of the leaf spring A locking portion (83a) provided on the moving body corresponding to the portion, and the locked portion of the leaf spring is locked to the corresponding locking portion of the moving body, respectively. Thus, the leaf spring is maintained in a curved state, and the curved convex side portion of the leaf spring becomes a fixed portion (79, 11, 12) with respect to the box body in the moving stroke of the movable body. On the other hand, it is configured so as to be substantially in a sliding contact state.

  Preferably, the movable body is slidably held by a long movement guide (79) provided in the box body along the longitudinal direction of the box body, and the plate moves in the movement stroke of the movable body. The convex side portion of the curved spring is substantially in sliding contact with the moving guide (claim 2).

  In addition, the code | symbol in the said parenthesis is an illustration.

  According to the first aspect of the present invention, it is possible to prevent the moving body from unintentionally moving in the box while being easy to assemble and having a simple configuration.

  According to the second aspect of the present invention, the movement guide can serve both as a guide function and a sliding contact function, so that the structure can be made simpler and more compact.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of a slide operation device according to an embodiment of the present invention. A box which is a casing of the slide operation device is formed by assembling a main case 10 and a sub case 40. FIG. 2 is a perspective view showing a state in which the sub case 40 is removed from the slide operation device.

  As shown in FIG. 2, the moving body 70 is housed in the main case 10 of the slide operation device together with the round bar-shaped upper guide bar 78 and the lower guide bar 79, and the upper part of the main case 10. Is provided with a long member 50 having a U-shaped cross section. A motor 59 is provided on one end side of the long member 50 in the longitudinal direction.

  A plurality of slide operation devices are mounted on a mixer device or the like as fader devices or the like, and the direction at the time of mounting is not fixed. Therefore, hereinafter, for convenience of explanation, the up, down, left, and right directions will be referred to based on the direction when viewed from the sub case 40 side with the knob 81 of the operation element 80 on the upper side. Therefore, it is assumed that the knob 81 side is the upper side, the motor 59 (see FIG. 2) side is the left side, and the front side in FIG. 2 is the front side.

  As shown in FIG. 2, the main case 10 has a bottom plate portion 11, a main plate 12 on the back side, a left side plate 13, a right side plate 14 and an upper plate portion 15. Further, both left and right end portions of the upper plate portion 15 extend forward and become attachment pieces 16 and 16 for attaching the long member 50. The main case 10 is formed by bending and forming a conductive metal plate such as a steel plate.

  The left side plate 13 and the right side plate 14 of the main case 10 have holding holes 20 and 21 for holding the upper guide bar 78 on the upper side and holding holes 22 and 23 for holding the lower guide bar 79 on the lower side, respectively. Each is formed on the side. As shown in FIG. 1, a cable insertion hole 24 is formed at the center of the main case 12 in the longitudinal direction of the main case 10.

  FIG. 3 is a plan view of the slide operating device. As shown in FIG. 2, the long member 50 is fixed to the main case 10 with screws 25 and 26 via the attachment piece 16 of the main case 10. As shown in FIGS. 2 and 3, a slit 55 for moving the operating element 80 along the longitudinal direction is formed at the bottom of the long member 50. Further, attachment pieces 51 and 52 are provided in the vicinity of both left and right end portions of the upper portion of the long member 50. The completed assembly type slide operation device is screwed into the holes (not shown) of the mounting pieces 51 and 52 with screws 53 and 54 via a panel plate or the like of the mixer device (not shown), so that the mixer device etc. It is attached.

  As shown in FIG. 3, a pulley 56 attached to an output shaft (not shown) of the motor 59 protrudes from the left end portion of the long member 50. A belt receiving pin 58 projects from the right end of the long member 50, and a rubber belt 57 is wound between the pulley 56 and the belt receiving pin 58. A belt attaching portion 85 is fixed to the operating element 80, and one place of the rubber belt 57 is fixed to the belt attaching portion 85. As a result, the knob portion 81 reciprocates along the longitudinal direction of the long member 50 together with the moving body 70 via the rubber belt 57 by forward and reverse rotation of the motor 59. For example, at the time of a scene recall or the like, a driving current is applied to the motor 59, and the moving body 70 is automatically driven to a desired position. In addition, the user can hold the knob 81 and move the moving body 70 to an arbitrary position by manual operation. The knob portion 81 is made of a conductive material (described later), but the knob portion 81 is covered with a grip portion 34 made of rubber or the like (see FIG. 2). Is operated by holding the holding portion 34.

  The sub case 40 (see FIG. 1) is integrally formed of resin or the like in a U shape in plan view. The sub case 40 is assembled to the main case 10 by snap fitting, for example, by engaging engaging portions (not shown). As shown in FIG. 1, the left side plate 41 of the sub case 40 is formed with notches 42 and 43 corresponding to the upper guide bar 78 and the lower guide bar 79. Although the right side plate of the sub case 40 is not illustrated, it is configured similarly to the left side plate 41 in the left-right symmetry.

  As shown in FIG. 2, the moving body 70 is also provided with a substrate 72. The board 72 is attached to the front surface of the rear portion 71a (see FIG. 4B) of the gondola 71 of the moving body 70 by screwing or the like through a board mounting hole (not shown). On the front surface of the substrate 72, a magnetic sensor unit 73 composed of an IC including a Hall element is disposed.

  A flat cable 30 is attached to the substrate 72. The flat cable 30 is disposed in the main case 10 and includes a cable base 31 fixed to the substrate 72 and an extending part 32 extending rightward from the cable base 31. The extending portion 32 is extended rightward through the cable escape portion 96a of the right wall portion 96 of the gondola 71, is bent rearward in the middle, and is folded leftward, so that the cable insertion hole 24 (FIG. 1). (See below). The extended portion 32 has a curved position that changes at any time according to the position of the moving body 70 in the left-right direction, and can follow the movement of the moving body 70.

  FIG. 4A is a schematic view of the moving body 70 as viewed from the front. FIG.4 (b) is sectional drawing which follows the AA line of the figure (a). In FIG. 4A, illustration of the substrate 72 and the sensor unit 73 is omitted.

  As shown in FIGS. 4A and 4B, the moving body 70 has a resin gondola 71 configured in a rectangular box shape with an opening on the front side, and the operating element 80 is fixed to the gondola 71. Become. The operation element 80 is composed of the above-described knob portion 81 that is T-shaped in front view and a fixed portion 82 that is lower than the knob portion 81 and has a rectangular shape in front view, and is integrally formed of a conductive material. A fixing portion 82 is fixed to the gondola 71 by outsert molding or adhesion.

  The left wall portion 95 and the right wall portion 96 of the gondola 71 are respectively formed with through holes (not shown) penetrating in the left-right direction one above the other. A guide bar 78 and a lower guide bar 79 penetrate therethrough. Thereby, the gondola 71 is slidable with respect to the upper guide bar 78 and the lower guide bar 79, and the movement is guided by the both guide bars 78, 79.

  The mechanism for detecting the position of the moving body 70 is a known mechanism similar to that disclosed in JP-A-2006-49302. First, as shown in FIG. 2, a magnetic pole surface 88 is provided on the lower surface of the upper guide bar 78 so as to finely polarize the N pole and the S pole over substantially the entire length in the longitudinal direction. Although not shown in the drawing, the lower surface of the magnetic pole surface 88 which is also the lower surface of the upper guide bar 78 is a flat surface. The position of the gondola 71 in the vertical and front-rear directions is regulated by the upper guide bar 78. That is, the upper guide bar 78 defines the trajectory of the gondola 71 movement. Thereby, the stable movement of the moving body 70 is ensured, and as a result, the position detection accuracy of the moving body 70 is high.

  Although not shown, a rotation prevention mechanism for the upper guide bar 78 is provided in any part of the box that is the casing of the slide operation device, and the magnetic pole surface 88 of the upper guide bar 78 always faces downward. It is like that. The anti-rotation mechanism includes, for example, the through hole (not shown) of the gondola 71 through which the upper guide bar 78 passes, or the holding holes 20 and 21 of the main case 10, and the cross-sectional shape of the upper guide bar 78 (a flat portion at the bottom) You may comprise by forming in the circle which has. The sensor unit 73 (see FIG. 2) faces the magnetic pole surface 88 with a slight gap (gap) with respect to the magnetic pole surface 88 of the upper guide bar 78 immediately below the upper guide bar 78.

  When the sensor unit 73 moves with respect to the magnetic pole surface 88 of the upper guide bar 78 as the moving body 70 moves, the sensor unit 73 performs a pulse corresponding to the reversal of the polarity between the N pole and the S pole of the magnetic pole surface 88. Output a signal. The amount of movement of the moving body 70 can be detected from the number of pulse signals. Further, the magnetic poles of the magnetic pole surface 88 are composed of, for example, two rows, and the magnetic pole pattern is shifted in phase by 1 / 2π in the longitudinal direction of the upper guide bar 78. Outputs a pulse signal out of phase. Therefore, the moving direction (right or left) of the moving body 70 is detected based on the opposite direction of the phase shift. Furthermore, the information on the position of the moving body 70 before moving is always stored by a control circuit in the mixer device (not shown). From the position information of the moving body 70 and the detected moving amount and moving direction, The current position of the moving body 70 is detected. It goes without saying that the moving operation of the moving body 70 is detected by the sensor unit 73 even in the manual operation.

  As shown in FIG. 2, in the state where the gondola 71 is engaged with the upper guide bar 78 and the lower guide bar 79, the upper guide bar 78 and the lower guide bar 79 have both ends at the holding holes of the main case 10. 20, 21 and holding holes 22 and 23 are respectively held by being inserted. At this time, the position of the upper guide bar 78 in the rotational direction is set so that the magnetic pole surface 88 faces downward.

  As shown in FIGS. 4A and 4B, holes 71b and 83 corresponding to each other are formed in the rear portion 71a of the gondola 71 of the moving body 70 and the fixing portion 82 of the operation element 80, respectively. In the hole 83 of the fixing portion 82, a pair of left and right cutout portions 83a is formed at a position where the lower guide bar 79 is disposed in the vertical direction. An escape portion 71ba is also formed in the hole 71b of the rear portion 71a of the gondola 71 corresponding to the notch portion 83a. A sliding contact assembly 60 is interposed between the lower guide bar 79 and the fixed portion 82. The sliding contact assembly 60 is engaged with and attached to the fixed portion 82.

  FIG. 5A is a front view of a leaf spring that constitutes a part of the sliding contact assembly 60. FIG. 5B is a front view of an insulating sheet constituting a part of the sliding contact assembly 60. FIG. 5C is a schematic view corresponding to a plan view showing an aspect of assembly of the sliding contact assembly 60 and engagement mounting to the fixing portion 82.

  The sliding contact assembly 60 is formed by assembling an insulating sheet 64 to a leaf spring 61. The leaf spring 61 is made of a conductive metal and has claw portions 63 at both longitudinal ends of the body portion 62. The leaf spring 61 has a bend that is curved as a single unit (convex upward in FIG. 4C), and pressing the convex side makes the posture stable even when the bending direction is reversed. It has the characteristics to be maintained. The leaf spring 61 may be flat in a free state.

  On the other hand, the insulating sheet 64 is integrally formed of an insulating material such as resin. As shown in FIG. 5B, a pair of engagement holes 66 corresponding to the claw portions 63 of the leaf springs 61 are formed at both ends in the longitudinal direction of the insulating sheet 64 and at the center in the longitudinal direction for discharge. One through hole 65 is formed. In order to create the sliding contact assembly 60, as shown in FIG. 5C, the plate spring is inserted into the engagement hole 66 of the insulating sheet 64 with the concave side of the plate spring 61 corresponding to the insulating sheet 64. Each of the 61 claw parts 63 is penetrated. Then, the convex side of the leaf spring 61 is pressed to reverse the bending direction of the leaf spring 61. Then, the insulating sheet 64 is brought into close contact with the newly convex surface of the leaf spring 61 so that they are integrated.

  5D is an enlarged view of a portion A in FIG. 5C, and FIG. 5E is an enlarged view of a portion B in FIG. 5C. The created sliding contact assembly 60 is attached to the gondola 71 at a stage before the upper guide bar 78 and the lower guide bar 79 are passed through the gondola 71. That is, as shown in FIGS. 4 (b) and 5 (d), the claw portion 63 of the leaf spring 61 protruding from the engagement hole 66 of the insulating sheet 64 is replaced with the notch portion 83 a of the hole 83 of the fixing portion 82. The sliding contact assembly 60 is mounted on the fixing portion 82 in a state of being maintained in a curved state by being inserted and locked. Thereafter, the upper guide bar 78 and the lower guide bar 79 are passed through the gondola 71.

  When the sliding contact assembly 60 is attached to the fixed portion 82, the sliding contact assembly 60 is curved so as to contact the lower guide bar 79. Strictly speaking, the central portion in the longitudinal direction of the insulating sheet 64 that is the convex portion of the sliding contact assembly 60 (just the position where the through hole 65 is located) abuts the lower guide bar 79 (see FIG. 5E). . This contact is also maintained when the moving body 70 moves, and the sliding contact assembly 60 is in sliding contact with the lower guide bar 79 during the entire movement of the moving body 70. Thereby, since suitable friction arises, the movement which the moving body 70 does not intend is suppressed. The leaf spring 61 itself is not in contact with the lower guide bar 79 during the entire movement of the moving body 70 due to the interposition of the insulating sheet 64. However, the insulating sheets 64 are close to each other with a constant interval corresponding to the thickness of the insulating sheet 64 (about 100 μm or less), and in particular, close to the inside of the through hole 65 without any inclusions.

  The frictional force between the sliding contact assembly 60 and the lower guide bar 79 is determined by factors such as the degree of curvature and length of the sliding contact assembly 60 and the spring constant of the leaf spring 61. For example, the frictional force is strong enough that the moving body 70 does not fall freely even when the slide operation device is mounted on the mixer device in such a posture that the lower guide bar 79 is in the vertical direction. Is set.

  FIG. 6A is a schematic diagram illustrating a state of wiring connection related to the operation element 80 and the substrate 72. In FIG. 2A, the gripping portion 34 is shown as a cross section. As described above, the grip portion 81 is covered with the grip portion 34 made of rubber or the like (see FIG. 2). As shown in FIG. 6A, the grip portion 34 is fitted and fixed to the knob portion 81. In the grip portion 34, the conductive plating portion 28 is continuously formed not only on the front side surface that is directly operated, but also on the inner side surface in contact with the knob portion 81. Therefore, the surface of the grip part 34 is in a state of being electrically connected to the fixed part 82 through the knob part 81.

  As wiring, there are a power line 92, three signal lines 93 (93-1, 93-2, 93-3) as lead lines for extracting signals output from the sensor unit 73, and a hum noise detecting line. 94 exists. Although not shown in FIG. 2, these lines are included in the flat cable 30 and are arranged in parallel along the longitudinal direction of the extending portion 32.

  In the substrate 72, the power supply line 92 and the three signal lines 93 are connected to the sensor unit 73. When this apparatus is used, a voltage of +5 V is applied to the power supply line 92. The pulse signal output from the sensor unit 73 is extracted by the signal line 93, and the current position of the moving body 70 is detected. The hum noise detection line 94 is electrically connected to the fixed portion 82 via the connection line 36, and both are always at the same potential.

  Further, when considering the path leading to the conductive plating portion 28, the knob portion 81, the fixing portion 82, the sliding contact assembly 60, the lower guide bar 79, and the main case 10, as described above, the sliding contact assembly 60 is provided. Only between the leaf spring 61 and the lower guide bar 79 is an electrically insulated portion having a distance corresponding to the thickness of the insulating sheet 64. The conductive plated portion 28 to the leaf spring 61 are electrically conductive and are not grounded. By the way, when the slide operating device is attached to the mixer device, the main case 10 is electrically grounded through the mixer device. Since the lower guide bar 79 is always in contact with the main case 10, the lower guide bar 79 is also in a grounded state.

  FIG. 6B is a block diagram of a touch detection circuit that realizes a touch sense function configured on the substrate 72. A plurality of slide operation devices having the same configuration are arranged in a mixer device (not shown), but the touch sense function is currently operated among the plurality of slide operation devices arranged. This is a function that makes the mixer device know. With this function, for example, in a mixer device, a channel corresponding to a slide operation device that is in contact with the gripping part 34 for operation by a user becomes active, or data can be rewritten according to the operation. It is. In the mixer device, the touch state is determined when the user touches the grip portion 34, and the non-touch state is determined when the finger is removed from the grip portion 34.

  The touch detection circuit 37 is provided in a slide operation device, and the mixer device is provided with a CPU 99. The touch detection circuit 37 includes an OSC (oscillator) 38 that generates a sine wave and various circuits 39. Various circuits 39 include, for example, a full-wave rectifier, a differential amplifier, an A / D converter, and the like, although not shown.

  As shown in FIG. 6A, the operator 80 (gripping part 34) is connected to the lower guide bar 79 with a high impedance, so that the same as the conductive plating part 28 of the gripping part 34. The hum noise detection line 94, which is a potential, picks up hum noise generated by the user's contact with the grip portion 34. By detecting this hum noise, a touch on the operating element 80 of the slide operating device is detected.

  That is, when the user touches the operating element 80 (the gripping portion 34), the capacitance of the system from the user's human body to the hum noise detection line 94 changes due to the resistance and capacitance of the user's body, and thus the OSC 38 (FIG. 6). The amplitude level of an LPF (low-pass filter) not shown in FIG. A change in amplitude at that time is detected by various circuits 39 and output to the CPU 99 as a change signal. Thereby, CPU99 of a mixer apparatus can grasp | ascertain the touch state / non-touch state in each slide operation device.

  In such a configuration, when a statically charged user operates the operation element 80, a high voltage is instantaneously applied to the leaf spring 61 through the conductive plating part 28, the knob part 81, and the fixing part 82 of the grip part 34. When an excessively high voltage (for example, 5 kV or more) is applied, a spark occurs between the leaf spring 61 and the lower guide bar 79 through the through hole 65, and discharge occurs through the lower guide bar 79 and the main case 10. Is done.

  According to the present embodiment, the curved convex side portion of the sliding contact assembly 60 is in sliding contact with the lower guide bar 79 in the entire movement of the moving body 70. Regardless of the posture of the present apparatus, it is possible to suppress the unintended movement of the moving body 70 within the housing. Moreover, the sliding contact assembly 60 includes a leaf spring 61 and an insulating sheet 64 (see FIG. 5C), and is attached to the fixed portion 82 by locking the claw portion 63 to the notch portion 83a. (See FIGS. 4 (b) and 5 (d)), fixing with screws or the like is not required, the configuration is simple, the cost is low, and the assembly is easy.

  Particularly, since the sensor unit 73 is a non-contact type and does not generate a physical resistance against the movement of the moving body 70, it is suitable for adopting a friction generating mechanism by the sliding contact assembly 60. It is. However, the sensor unit 73 may not be a non-contact method such as a magnetic sensor or an optical sensor, and the method is not limited.

  The sliding contact assembly 60 is slidably contacted with the lower guide bar 79, which functions as both the moving guide function of the moving body 70 and the brake function by sliding contact. Is easy.

  Also according to the present embodiment, since the leaf spring 61 of the sliding contact assembly 60 is always in non-contact with the lower guide bar 79 in the entire movement of the moving body 70, the touch sensing function is realized. be able to. Nevertheless, in the entire moving process of the moving body 70, the insulating sheet 64 of the sliding contact assembly 60 is in sliding contact with the lower guide bar 79, and the leaf spring 61 is constant by the thickness of the insulating sheet 64. Since the gaps are always close to each other with a gap therebetween, a discharge path for static electricity applied to the operation element 80 can always be secured through the through hole 65 of the insulating sheet 64. As a result, while realizing the touch sense function, even if a user with high static electricity touches the operation element 80, the possibility of causing a malfunction or failure due to a high voltage is reduced.

  Various modifications may be employed as will be described with reference to FIGS.

  FIGS. 7A to 7D are views showing a first modification of the operation element 80 and the sliding contact assembly 60. FIG. FIG. 4A is a partial front view of the fixing portion 82 of the operating element 80, and FIGS. 4B to 4D are front views of the sliding contact assembly 60 having different lengths. As shown in FIGS. 5B to 5D, a plurality of types (for example, three types) of sliding contact assemblies 60A to 60C having different lengths are provided. At the same time, as shown in FIG. 5A, the fixing portion 82 of the operation element 80 is provided with a pair of engagement holes 86 (86A, 86B). When the sliding contact assembly 60 is mounted on the fixed portion 82, one of the sliding contact assemblies 60A to 60C is selected, and the claw portion 63 of the selected sliding contact assembly 60 is engaged with the engagement hole 86A. , 86B. Thereby, the degree of curvature of the sliding contact assembly 60 or the contact strength with the lower guide bar 79 can be adjusted, and the generated frictional force can be adjusted. In this example, six stages of adjustments are possible depending on the combination of the sliding contact assembly 60 to be selected and the engagement hole 86 for locking the claw 63. The number of types of the sliding contact assemblies 60 and the number of pairs of the engagement holes 86 are examples, and may be increased.

  Moreover, in the said embodiment, the insulating sheet 64 of the assembly 60 for sliding contact played the role which maintained the leaf | plate spring 61 and the lower side guide bar 79 at the fixed space | interval which adjoined. However, from the standpoint of securing the discharge path, the conductive portion that is spaced from the lower guide bar 79 is at the same potential as the conductive plating portion 28 of the operation element 80 (see FIG. 6A). Any conductive portion provided on the moving body 70 side may be used, and the plate spring 61 is not limited.

  FIG.7 (e) is a horizontal sectional view which shows the 2nd modification of the assembly for sliding contact. As shown in FIG. 4E, a curved elastic insulating member 164 is brought into contact with the lower guide bar 79. The conductor 67 is fixed in a buried state in the hole 165 of the insulating member 164, and a constant interval is provided between the tip 67 a of the conductor 67 and the lower guide bar 79. Although not shown, the conductor 67 is set to the same potential as the conductive plating portion 28 through the fixing portion 82. In addition, as the insulating member 164, a member having no spring property may be employed. In that case, it may be configured by a combination of a sheet and a leaf spring similar to the insulating sheet 64, and the leaf spring may be used only for maintaining the curved state of the sheet, not the discharge path.

  Even in the configuration of the second modified example, when high static electricity is applied to the operation element 80, a discharge path is formed in the hole 165 between the tip 67a of the conductor 67 and the lower guide bar 79. With respect to securing the discharge path, the same effects as in the above embodiment can be obtained.

  Moreover, in the said embodiment, although the assembly 60 for sliding contact was assembled | attached and comprised with the insulating sheet 64 and the leaf | plate spring 61, it is not restricted to this. FIG. 7F is a front view showing a third modification of the sliding contact assembly. In the sliding contact assembly 160, the insulating coating 68 is applied to the surface of the leaf spring 61 on the side facing the lower guide bar 79. The insulating coating 68 is provided with a non-coating portion 68a corresponding to the through hole 65 (see FIG. 5B) for securing a discharge path.

  Further, in the above embodiment, the object to which the sliding contact assembly 60 is slidably contacted is the lower guide bar 79. However, when the effect of combining the movement guide function of the moving body 70 and the brake function by sliding contact is not required, the object to be slid contacted is the main case 10 as illustrated in FIGS. On the other hand, any portion that is a fixed portion and is in an electrically conductive state with respect to the main case 10 may be used.

  FIGS. 8A and 8B are a side view and a plan view schematically showing a modification of the arrangement mode of the sliding contact assembly 60. As shown in FIGS. 8A and 8B, the sliding contact assembly 60 is attached to the fixed portion 82 of the operation element 80, and the curved convex side is the rear, that is, the main plate 12 of the main case 10. It is arranged to face the side. Then, the convex side portion of the sliding contact assembly 60 is in sliding contact with the main plate 12 in the entire moving process of the moving body 70.

  FIGS. 8C and 8D are a side view and a front view schematically showing another modified example of the arrangement mode of the sliding contact assembly 60. As shown in FIGS. 8C and 8D, the fixing portion 82 of the operation element 80 has an extending portion 82a that extends forward in the lower portion. The sliding contact assembly 60 is mounted on the extending portion 82a of the fixed portion 82, and is disposed so that the curved convex side faces downward, that is, the bottom plate portion 11 side of the main case 10. Then, during the entire movement of the moving body 70, the convex side portion of the sliding contact assembly 60 comes into sliding contact with the bottom plate portion 11.

  Moreover, in the said embodiment, the insulating sheet 64 which is an insulating part which performs an insulating function in the path | route from the operation element 80 to the main case 10 was provided in the moving body 70 which is a moving side. However, as illustrated in FIGS. 9A to 9D, the insulating portion may be provided on the fixed side of the main case 10 or the like, or on both the moving side and the fixed side.

  FIGS. 9A, 9B, and 9C are a perspective view, a plan view, and a front view schematically showing a modification of the arrangement of the insulating portions. As shown in FIGS. 9A to 9C, the insulating portion 97 (97A, 97B) is fixed to the front surface of the main plate 12 of the main case 10 along the left-right direction. A slit 98 for providing a discharge path is provided between the insulating portions 97A and 97B in the same manner as the through hole 65 (see FIG. 5B). The thickness of the insulating portion 97 is approximately the same as that of the insulating sheet 64 (see FIG. 5B).

  On the other hand, the slidable contact leaf spring 260 corresponding to the slidable contact assembly 60 is configured as a single plate spring without the insulating sheet 64 being assembled. The slidable contact leaf spring 260 is attached to the fixed portion 82 of the operation element 80, and is arranged so that the curved convex side faces rearward, that is, the main plate 12 side of the main case 10. In the entire travel of the movable body 70, the convex side portion of the sliding contact leaf spring 260 is in sliding contact with both of the insulating portions 97A and 97B, and maintains an interval corresponding to the thickness of the insulating portion 97 with respect to the main plate 12. .

  In this configuration, when high static electricity is applied to the operation element 80, a discharge path is formed between the sliding plate spring 260 and the main plate 12 in the slit 98. The same effect can be achieved.

  In addition, as FIG.9 (d) shows typically the other modification of the arrangement | positioning aspect of an insulating part, you may provide an insulating part in both the movement side and a fixed side. That is, on the fixed side, the insulating portions 97A and 97B are provided on the main plate 12 of the main case 10 in the same manner as in FIGS. On the other hand, on the moving side, a sliding contact assembly 60 (see FIG. 5) including the leaf spring 61 and the insulating sheet 64 is provided. In this case, a discharge path is formed in the slit 98 between the insulating portions 97A and 97B and the through hole 65 of the insulating sheet 64. However, in this case, since the distance between the main plate 12 and the leaf spring 61 is the sum of the thickness of the insulating portion 97 and the thickness of the insulating sheet 64, the sum of both thicknesses is set to about 100 μm or less and the distance is set appropriately. It is desirable to do.

  In the above-described embodiment and each modification, in order to allow the sliding contact assemblies 60, 160, and 260 to be attached to the fixing portion 82 of the operation element 80, the claw portion 63 and the fixing portion 82 are attached to the leaf spring 61. Although the notch 83a and the engagement hole 86 are provided in the above, it is sufficient that the sliding contact assembly 60 and the like can be maintained in a curved state, and the configuration is not limited to the exemplified one. For example, in place of the notch 83a and the engagement hole 86, a form such as a recess may be used. Further, the leaf spring 61 may be provided with a notch or an engagement hole, and the fixing portion 82 may be provided with a claw portion. Furthermore, two or more to-be-latched parts, such as a nail | claw part, may be provided in each right and left, and according to it, multiple latching parts, such as a notch part and an engagement hole, may be provided.

  If it is not necessary to provide the touch sense function, static electricity noise can be obtained if the operating element 80 and the main case 10 are kept at the same potential in advance by, for example, eliminating the insulating sheet 64 in the sliding assembly 60. It is easy to secure measures.
