Description

  The present invention relates to a movable accessory device provided in a ball game machine, and in particular, includes a rotating plate that rotates the front of a display screen of a variable display device in both forward and reverse directions, and the display screen is visible on the rotating plate. The present invention relates to a movable accessory device provided with an opening.

  In some ball game machines represented by pachinko machines, a variable display device and a start prize opening are arranged in the game area of the game board, and the game balls launched toward the game area enter the start prize opening. There are many models in which electronic lottery is performed in response to this, and the variable display device performs variable display and stop display of symbols based on the lottery result. Electronic lottery results include winning (winning) and losing (non-winning). When the lottery results are winning, a special combination of symbols is displayed on the display screen of the variable display device. Transition to game mode. In this special game mode, for example, a game ball enters a big winning opening exposed by opening an attacker, so that the player can acquire many prize balls.

  In such a ball game machine, a movable body capable of changing the movable mode is arranged at an appropriate position in the game area (for example, around the variable display device), and it is movable to the player that the player is elected by electronic lottery. Movable accessory devices that are suggested by the manner in which the body moves are widely used. Such a movable accessory device includes an actuator composed of a motor, a solenoid, and the like, and a movable body that performs various motions using the actuator as a drive source. Conventionally, a ring-shaped rotating plate having an opening is variable. It is arranged around the display device, and this rotating plate is rotated by a predetermined angle in both forward and reverse directions by a rotation drive mechanism, thereby associating the display contents of the variable display device viewed through the opening with the rotating operation of the rotating plate. Such a movable accessory device is known (for example, see Patent Document 1).

  In the conventional movable accessory device disclosed in Patent Document 1, an opening through which the display screen of the variable display device can be seen is formed at the center of the rotating plate, and an annular ring gear is formed inside the outer peripheral edge of the rotating plate. Is provided. The outer peripheral edge of the rotating plate is supported on a supporting base integral with the game board using a plurality of rollers, and a driving motor and a reduction gear train constituting a rotational driving mechanism are mounted on the supporting base. The reduction gear train is composed of a plurality of gears having different numbers of teeth, the first stage gear is fixed to the output shaft of the drive motor, and the last stage gear meshes with the ring gear of the rotating plate. Therefore, when the drive motor rotates forward or backward, the rotation is transmitted from the reduction gear train to the rotating plate via the ring gear, and accordingly, the rotating plate is either forward or reverse in front of the display screen of the variable display device. Since the image is rotated by a predetermined angle in the direction, it is possible to perform an effect in which the rotation operation of the rotating plate is associated with the display content of the display screen.

  By the way, in the conventional movable accessory device described above, the rotating plate having the opening simply rotates in front of the display screen, so that the rotating plate is decorated with gorgeous decoration, the rotating operation of the rotating plate and the display screen. Even if the display contents are associated with each other, it is difficult to make the rotating operation of the rotating plate stand out. Therefore, a movable body that imitates a door, character, etc. and an actuator such as a motor or solenoid are mounted on such a rotating plate, and the actuator enters the opening whose relative angle changes with the display screen according to the rotating operation of the rotating plate. It is conceivable to realize a novel and impactful production that has never existed in the past by moving the movable body in and out using as a drive source. However, in this case, since a heavy actuator needs to be mounted on the rotating plate together with the movable body, the total weight of the rotating plate increases remarkably, and accordingly, a large burden is placed on the drive motor that rotates the rotating plate. A new problem occurs.

  The present invention has been made in view of the situation of the prior art as described above, and an object of the present invention is to smoothly rotate a rotating plate on which a movable body capable of entering and exiting the opening is mounted in front of the variable display device. An object of the present invention is to provide a movable accessory device.

In order to achieve the above object, the present invention provides a movable accessory device that is arranged behind a decorative case having a through hole provided in a game area of a game board and is movable in front of a variable display device. A rotating plate having an opening at a central portion where the display screen of the variable display device can be visually observed, a support base that rotatably supports the rotating plate via a plurality of rollers, and the rotating plate A rotation drive mechanism that rotates the image at a predetermined angle from the initial position in both forward and reverse directions within a plane substantially parallel to the disk surface, and a movable body that can enter and exit the opening using an actuator mounted on the rotating plate as a drive source.

Therefore, the movable body that moves in and out of the opening by moving the movable body into and out of the opening whose relative angle changes with the display screen according to the rotation of the rotating plate. A novel and impactful production can be realized by associating with the display content. In addition, the total weight of the rotary plate on which the movable body and the actuator are mounted is large, but the rotary drive mechanism that rotates the rotary plate is driven by the drive motor mounted on the support base and the output shaft of the drive motor. A reduction gear train interposed between ring gears provided on the outer peripheral surface of the plate, and the final gear and the ring gear of the reduction gear train are positioned in the vicinity of a perpendicular passing through the rotation center of the rotating plate. Because of the meshing, the load torque applied to the drive motor when rotating the rotating plate from the initial position in the forward direction and the reverse direction is equalized, and the rotating plate can be smoothly rotated in front of the variable display device.

In the above configuration, the fall prevention piece which faces are provided with presence an outer circumferential surface a predetermined distance of the rotation plate to the lower side of the support base, the fall prevention member in the vicinity of the final gear of the reduction gear train If the outer peripheral edge of the rotating plate is in contact with the upper end of the fall prevention piece, if the further movement is restricted , the roller supporting the rotating plate should be damaged, Even if the rotating plate comes off the roller due to external impact force, etc., the rotating plate will not drop any more when it comes into contact with the fall prevention piece, so it is possible to reliably prevent the rotating plate from dropping. It is preferable.

In the above configuration, a small diameter portion is provided in the upper portion of the rotating plate at the initial position, and a large diameter portion having a diameter larger than the small diameter portion is provided in the lower portion thereof, and these small diameter portions are provided. And the large-diameter portion are continuous via a pair of left and right flat portions, and the support base is provided with a pair of stopper protrusions that are opposed to each other via a perpendicular line passing through the rotation center of the rotation plate. If it is configured so that one flat part and one stopper projection abut when rotating in either the forward or reverse direction based on the position, the height dimension of the rotating plate rotating in both forward and reverse directions can be suppressed. This is preferable.

  In the above configuration, the number of movable bodies and the movement form are not particularly limited, but the movable body is composed of a pair of slide plates that can reciprocate in the direction of approaching and leaving the opening, and It consists of a pair of motors mounted on a rotating plate with the perpendicular passing through the center of rotation as the axis of symmetry, and has a pair of screw shafts that convert the rotational motion of each motor into the linear motion of the corresponding slide plate. When supported by the rotating plate in a state shifted in the front-rear direction on the same plane substantially orthogonal to the axis, the pair of slide plates can be compactly arranged around the variable display device having a large display screen.

Has been placed.

  As shown in FIGS. 7 and 8, a rectangular opening 33 is formed at the center of the synthetic resin rotating plate 23, and the display screen 14 a of the variable display device 14 can be seen through the opening 33. ing. The upper portion of the rotating plate 23 is a small diameter portion 23a, and the small diameter portion 23a and the large diameter portion 23b below the small diameter portion 23a are continuous via a pair of left and right flat portions 23c. A pair of guide holes 23e are formed below the small diameter portion 23a, and these guide holes 23e extend in the left-right direction along the upper side of the opening 33. Further, a thin portion 23d is formed on the outer peripheral edges of the small diameter portion 23a and the large diameter portion 23b, and the thin plate portion 23d is supported by three rollers 34 as shown in FIG. Is rotatably supported on the support base 22 via each roller 34. All of these rollers 34 have a double roller structure, which will be described later. Hereinafter, this double roller structure will be described by taking as an example a roller 34 that supports the lower left portion of the rotating plate 23.

  As shown in FIG. 6, the roller 34 that supports the lower left portion of the rotating plate 23 includes an upper roller half 34a and a lower roller half 34b that sandwich the thin portion 23d of the rotating plate 23 in the plate thickness direction. The upper roller half 34 a and the lower roller half 34 b are coaxially arranged on a support shaft 35 planted on the support base 22, and are supported rotatably about the support shaft 35. However, a gap S1 is formed between the outer peripheral end of the thin portion 23d and the shaft portion of the upper roller half 34a, and the thin portion 23d is in the radial direction with respect to the upper roller half 34a and the lower roller half 34b. Contactless. The roller 34 that supports the lower right portion of the rotating plate 23 has the same configuration. When the left and right lower portions of the rotating plate 23 are supported by the roller 34 having the double roller structure, the upper roller half 34a having a large diameter and the lower It is possible to rotate the rotating plate 23 smoothly by reducing the frictional resistance generated between the rotating plate 23 and the roller 34 after the rotating plate 23 is reliably supported by the side roller half-off 34b. The remaining roller 34 that supports the central upper portion of the rotating plate 23 has a similar double roller structure with a slightly smaller diameter. However, since the weight of the rotating plate 23 does not act on the roller 34 at the upper center, the roller 34 does not necessarily have a double roller structure, and a general single roller structure roller can also be used.

  As shown in FIG. 3, a ring gear 36 is attached to the lower outer peripheral edge on the surface side of the rotating plate 23, and the final gear 30 b of the reduction gear train 30 described above is a perpendicular line passing through the rotation center O of the rotating plate 23.

As a result, the rotation of the drive motor 29 is transmitted to the rotating plate 23 via the reduction gear train 30, and the drive motor 29, the reduction gear train 30 and the ring gear 36 constitute a rotation drive mechanism. In the case of this embodiment, the rotary drive mechanism rotates the rotary plate 23 by about 45 degrees in both forward and reverse directions (clockwise and counterclockwise) with reference to the initial position. The rotation angle of the rotating plate 23 in the clockwise direction is regulated by the left flat portion 23c coming into contact with one stopper projection 27, and the rotation angle of the rotating plate 23 in the counterclockwise direction is controlled by the right flat portion 23c. It is regulated by coming into contact with the other stopper projection 28. Further, the outer peripheral edge of the rotating plate 23 and the above-described drop prevention piece 24 are opposed to each other with a predetermined interval, so that the fall prevention piece 24 does not hinder the rotation operation of the rotation plate 23. However, when the roller 34 supporting the rotating plate 23 is damaged or the rotating plate 23 is detached from the roller 34 due to an external impact or the like, the outer peripheral edge of the rotating plate 23 contacts the upper end of the fall prevention piece 24. Since the further movement is restricted at the time, the fall accident of the rotating plate 23 can be surely prevented.

  As shown in FIG. 8, a light shielding plate 37 is attached to the outer peripheral edge on the back surface side of the rotating plate 23, and a short light shielding wall 37a and a long light shielding wall 37b stand up concentrically on the light shielding plate 37. It is installed. The pair of photo interrupters 25 and 26 described above are located on the rotation locus of the light shielding walls 37a and 37b, and the initial position and the rotation direction of the rotating plate 23 can be detected based on the output signals of both the photo interrupters 25 and 26. It is like that. Specifically, when the rotating plate 23 is in the initial position, the short light shielding wall 37a is in a position crossing the optical path of one photointerrupter 25, and the long light shielding wall 37b crosses the optical path of the other photointerrupter 26. Since it is in the position, both of the photo interrupters 25 and 26 output off signals. Further, when the rotating plate 23 rotates clockwise from the initial position, the short light shielding wall 37a moves to a position deviating from the optical path of one photointerrupter 25, and the long light shielding wall 37b also moves from the optical path of the other photointerrupter 26. In order to move to a position that deviates, both of the photo interrupters 25 and 26 output ON signals. On the contrary, when the rotating plate 23 rotates counterclockwise from the initial position, the short light shielding wall 37a moves to a position out of the optical path of one photo interrupter 25, while the long light shielding wall 37b moves to the other photo interrupter. In order to move in the optical path 26, an on signal is output from one photo interrupter 25 and an off signal is output from the other photo interrupter 26.

A pinion 48 is fixed to one end portion of the first screw shaft 43, and the rotation of the first motor 42 is connected to the first screw shaft 43 by connecting the pinion 48 and the pinion 46 via a relay gear 49. It is to be transmitted. Further, a pinion 50 is fixed to one end of the second screw shaft 45. By connecting the pinion 50 and the pinion 47 via the relay gear 51, the rotation of the second motor 44 is rotated to the second screw shaft 45. 45 is transmitted. That is, the first screw shaft 43 extends from the output shaft of the first motor 42 toward the second motor 44, and the second screw shaft 45 extends from the output shaft of the second motor 44 toward the first motor 42. I'm out.

  Here, in this embodiment, the distance between the first slide plate 40 and the second slide plate 41 is intentionally changed, and the distance between the opposite ends on the free end (upper end) side of both slide plates 40 and 41 is changed. On the other hand, the distance between the opposing ends on the drive end (lower end) side is set in advance. For this reason, as shown in FIG. 15, when the corner portions on the free end side of the first slide plate 40 and the second slide plate 41 are in contact with each other, the corner portions on the drive end side are not yet in contact with each other, A triangular gap S <b> 2 is formed between the opposing surfaces of the first slide plate 40 and the second slide plate 41 with the drive end side as the base. When the rotation of the first motor 42 and the second motor 44 is continued from this state, the first slide plate 40 and the second slide plate 41 move so as to narrow the bottom of the gap S2 while keeping the free end side in contact, The rotations of the first motor 42 and the second motor 44 are stopped when the corners on the driving end side of the first slide plate 40 and the second slide plate 41 come into contact with each other. As a result, as shown in FIG. 16, the variable display device in which the opposing surfaces of the first slide plate 40 and the second slide plate 41 are in contact with each other from the free end side to the drive end side and face the opening 33. 14 display screens 14 a are reliably shielded by the first slide plate 40 and the second slide plate 41.

  As shown in FIGS. 17 and 18, the cable guide 31 is composed of a rear case 31a and a front case 31b. These cases 31a and 31b are fixed to the support base 22 in a joined and integrated state. ing. A circuit board 56 is housed inside the cable guide 31, and this circuit board 56 is connected to a control board (not shown) disposed on the back side of the game board 3. In addition, two fixed-side connectors 57 are mounted on the circuit board 56, and one end portions of the two flat cables 32 are connected to the fixed-side connector 57, and the other end portions of the two flat cables 32 are connected to each other. It is connected to a movable connector 58 attached to the outer periphery of the rotating plate 23 (see FIG. 3). Therefore, the control signals from the control board are applied to the electric components such as the motors 42 and 44 mounted on the rotating plate 23 rotating in both the forward and reverse directions and the LEDs in the slide plates 40 and 41 regardless of the rotation angle. Can be reliably transmitted via the flat cable 32. The two flat cables 32 are stacked in close contact except for the connection portion with the fixed connector 57. Since the appearance is not much different from one flat cable, the two flat cables 32 will be referred to below. It will be described as a single sheet.

  The inner wall surface facing the arcuate space S of the cable guide 31 has a curved surface shape, and a guide groove 59 is formed in the entire region from the upper end portion to the lower end portion of the inner wall surface. A guide port 60 is formed at a position slightly below the center of the guide groove 59, and the flat cable 32 connected to the fixed connector 57 inside the cable guide 31 is led out downward from the guide port 60. After that, the direction is changed upward by the reversing part 32 a and connected to the movable connector 58 of the rotating plate 23. The guide groove 59 has a function of regulating the position of the flat cable 32 led out from the lead-out port 60 in the width direction, and the width dimension is set to be the same throughout the extending direction of the guide groove 59. The dimensions are partially changed in the extending direction of the guide groove 59. Specifically, the depth dimension of the guide groove 59 is gradually increased downward from the outlet 60, and is set to have the maximum depth d1 at the deepest position 59a above the lower end of the guide groove 59. . A portion from the outlet 60 to the upper end of the guide groove 59 is an extension guide 59b. The groove depth of the extension guide 59b is set to the same minimum depth d2 as the vicinity of the outlet 60. Yes.

  The relative position between the guide groove 59 and the reversing portion 32a of the flat cable 32 varies depending on the rotation angle of the rotating plate 23. When the rotating plate 23 is at the initial position, the reversing portion 32a is indicated by a solid line in FIG. The guide groove 59 is located in the vicinity of the deepest position 59a. In this case, the distance between the groove bottom surface of the guide groove 59 and the outer peripheral edge of the rotating plate 23 (the width dimension of the arcuate space S) becomes maximum at the deepest position 59a, so that the radius of curvature of the reversing portion 32a can be kept sufficiently large. This reduces the bending stress on the flat cable 32. When the rotating plate 23 rotates clockwise from the initial position, the reversing portion 32a is displaced to a position protruding from the lower end portion of the guide groove 59 as shown by a two-dot chain line in FIG. Since the portion of the flat cable 32 reaching the reversing portion 32a is regulated in the width direction by the guide groove 59, the reversing portion 32a protruding from the guide groove 59 does not collide with surrounding members and be damaged. On the contrary, when the rotating plate 23 rotates counterclockwise from the initial position, the reversing portion 32a moves away from the deepest position 59a of the guide groove 59 to the vicinity of the outlet 60 as shown by the broken line in FIG. However, in this case, the bending radius applied to the flat cable 32 is reduced because the radius of curvature of the reversing portion 32a is kept large by the presence of the outlet 60. Moreover, since the groove depth of the guide groove 59 is set so as to gradually increase from the outlet 60 toward the deepest position 59a, when the rotating plate 23 rotated to the end position in the counterclockwise direction is returned to the initial position, The reversing part 32a can be smoothly moved in the guide groove 59 and guided to the vicinity of the deepest position 59a.

  Next, the operation of the movable accessory device 13 configured as described above will be described mainly with reference to FIGS. 19 to 21 are operation explanatory views of the movable accessory device 13 as viewed from the front side of the game board 3, and both the slide plates 40 and 41 mounted on the rotating plate 23 and the both motors which are driving devices thereof. 42 and 44 and both screw shafts 43 and 45 are not shown.

  In the movable accessory device 13 according to the present embodiment example, the rotating plate 23 is in the initial position shown in FIG. 19 in a normal gaming state, and the opening 33 of the rotating plate 23 and the through hole 11 of the decorative case 12 are in this initial position. It is kept in a matching landscape shape. In this case, the first slide plate 40 and the second slide plate 41 are in the retracted positions hidden on the left and right sides of the opening 33, and the display screen 14 a of the variable display device 14 is exposed in the opening 33 through the through hole 22 a of the support base 22. doing. In addition, the movable connector 58 attached to the outer peripheral portion of the rotating plate 23 faces the central portion of the cable guide 31 through the arc space S, and the reversing portion 32 a of the flat cable 32 connected to the movable connector 58. Is located in the vicinity of the deepest position 59 a of the guide groove 59 formed on the inner wall surface of the cable guide 31.

  When the drive motor 29 is rotationally driven in either of the forward and reverse directions in this state, the rotation of the drive motor 29 is transmitted from the reduction gear train 30 to the rotary plate 23 via the ring gear 36, so that the rotary plate 23 is moved from the initial position. Rotate clockwise. Then, when the rotating plate 23 is rotated clockwise by about 45 degrees from the initial position, as shown in FIG. 20, the flat portion 23c on the left side of the rotating plate 23 comes into contact with one stopper projection 27, and the drive motor is at that position. 29 is stopped to stop the rotation of the rotating plate 23. As a result, the opening 33 is inclined 45 degrees to the right with respect to the display screen 14 a, and a part of the decorative cover 38 disposed on the front surface of the rotating plate 23 is exposed from the through hole 11 of the decorative case 12. As the rotating plate 23 rotates, the movable connector 58 moves to the vicinity of the lower end of the cable guide 31, and the reversing portion 32 a of the flat cable 32 moves downward from the deepest position 59 a of the guide groove 59. Therefore, the portion of the flat cable 32 extending from the movable connector 58 to the lower end portion of the cable guide 31 becomes the reversing portion 32a having a large curvature radius.

  On the other hand, when the drive motor 29 is rotationally driven to the other side with the rotary plate 23 in the initial position, the rotary plate 23 rotates counterclockwise from the initial position. When the rotating plate 23 rotates counterclockwise from the initial position to about 45 degrees, as shown in FIG. 21, the flat portion 23c on the right side of the rotating plate 23 comes into contact with the other stopper projection 28 and is driven at that position. The driving of the motor 29 is stopped and the rotation of the rotating plate 23 is stopped. As a result, the opening 33 is inclined 45 degrees to the left with respect to the display screen 14 a, and a part of the decorative cover 38 is exposed from the through hole 11 of the decorative case 12. Further, as the rotating plate 23 rotates, the movable connector 58 moves to the vicinity of the upper end portion of the cable guide 31, and the reversing portion 32 a of the flat cable 32 follows the lead port 60 from the deepest position 59 a of the guide groove 59. Therefore, the flat cable 32 led out from the lead-out port 60 reaches the movable connector 58 through the arcuate space S facing the extension guide portion 59b. In this case, although the width dimension of the arc-shaped space S located on the side of the outlet 60 is narrower than that of the deepest position 59a, the presence of the outlet 60 formed by cutting out the groove bottom surface of the guide groove 59 is provided. Since the curvature radius of the reversing part 32a is kept large, the bending stress applied to the flat cable 32 is reduced. In addition, the rotating plate 23 is maintained at the initial position in most cases, and the frequency of the rotating plate 23 rotating to the position shown in FIG. Even if it becomes temporarily small, there is no possibility that the flat cable 32 may be damaged thereby.

  Further, when the rotary plate 23 is in an arbitrary rotational position including the initial position in this way, the slide plates 40 and 41 are opened and closed by performing the opening and closing operations of the first slide plate 40 and the second slide plate 41 described above. It is possible to realize an effect with an impact that associates the opening / closing direction of the image and the display content of the variable display device 14. For example, both slide plates 40 and 41 are reciprocated horizontally with respect to the display screen 14a while keeping the rotating plate 23 at the initial position during normal reach, or the rotating plate 23 is rotated clockwise or counterclockwise during super reach. If the slide plates 40, 41 are reciprocated in the oblique direction with respect to the display screen 14a during the rotation or at the rotation end position, the jackpot is made according to the opening / closing operation and the opening / closing direction of the slide plates 40, 41. It is possible to make the player suggest the degree of possibility.

  As described above, in the movable accessory device 13 according to the present embodiment, the pair of slide plates 40 and 41 and the pair of slide plates 40 and 41 are provided on the rotary plate 23 provided with the opening 33 through which the display screen 14a of the variable display device 14 can be viewed. Motors 42, 44, etc. are mounted, and the rotating plate 23 is driven to rotate in both forward and reverse directions from the initial position, so that the relative angle with the display screen 14a changes according to the rotating operation of the rotating plate 23. By moving the slide plates 40 and 41 into and out of the opening 33, the slide plates 40 and 41 that reciprocate in the opening 33 are associated with the display content of the display screen 14a to realize a novel and impactful effect. Can do. In addition, the drive motor 29 mounted on the support base 22 and the reduction gear train 30 that transmits the rotation of the drive motor 29 to the ring gear 36 on the outer periphery of the rotary plate 23 constitute a rotational drive mechanism. Since the final gear 30b and the ring gear 36 are engaged in the vicinity of the perpendicular L passing through the rotation center O of the rotating plate 23, the drive motor 29 for rotating the rotating plate 23 from the initial position in the forward direction and in the reverse direction. The rotating plate 23 having a large total weight can be smoothly rotated in front of the variable display device 14.

  Further, a drop prevention piece 24 that is opposed to the outer peripheral surface of the rotating plate 23 with a predetermined interval is integrally formed on the support base 22, and the drop preventing piece 24 is positioned on a perpendicular L that passes through the rotation center O of the rotating plate 23. Therefore, even if the roller 34 supporting the rotating plate 24 is damaged or the rotating plate 23 is detached from the roller 34 due to an external impact force or the like, the rotating plate 23 contacts the fall prevention piece 24. At the time of contact, it does not fall any further, and the fall accident of the rotating plate 23 can be reliably prevented.

  Further, a thin-walled portion 23d extending in a ring shape is formed on the outer peripheral edge of the rotating plate 23, and at least two rollers 34 supporting the left and right lower portions of the rotating plate 23 plate the thin-walled portion 23d with a pair of roller halves 34a and 34b. Since the double roller structure sandwiched in the thickness direction is formed and the gap S1 is formed between the outer peripheral end of the thin portion 23d and both roller halves 34a, 34b, the roller halves 34a, The rotating plate 23 can be smoothly rotated by reducing the frictional resistance generated between the thin-walled portion 23d and the roller 34 after the rotating plate 23 is securely supported by 34b.

  In the above embodiment, the slide plates 40 and 41, the motors 42 and 44, and the screw shafts 43 and 45 are mounted on the rotary plate 23, and the slide plates 40 and 44 are rotated by the screw shafts 43 and 45, respectively. , 41 has been described with respect to the movable accessory device 13 in which the pair of slide plates 40, 41, which are movable bodies, move within the opening 33 of the rotating plate 23 in the approaching / separating direction. The number of bodies, the form of motion, and the like are not limited thereto, and one or three or more movable bodies may be moved in and out of the opening 33 using an actuator such as a solenoid or a motor as a drive source.
