Description

  According to the present invention, for example, a movable platen surface component that is driven back and forth on a predetermined movement path by a drive mechanism using a gear, a wire, or the like is in a normal stop position due to play caused by a dimensional tolerance of components constituting the drive mechanism or the like. The present invention relates to a gaming machine that has solved the problem of being unable to stop.

  In pachinko machines, various board parts such as a prize opening, windmill, variable display device, and lighting device are provided on the board surface of the game board in order to diversify the contents of the game, winning prizes during the game, and other situation changes The stage effect is enhanced by moving the movable panel surface parts in various directions.

For example, when a game ball wins a start winning opening provided on the game board, the symbol displayed on the variable display device in the game board starts to change, and the symbol stopped after a predetermined time elapses is a predetermined jackpot symbol. When it becomes, it becomes a big hit state, and a player can acquire a lot of balls. In such a gaming machine, various display effects are performed in order to enhance the interest of the game.
For example, in Patent Document 1 related to the proposal of the present applicant, a shoji that opens and closes a display surface of a liquid crystal display device arranged in a game area and a door opening and closing member are opened and closed in a direction substantially parallel to the board surface, and are moved in and out. Has proposed a movable panel surface component that is capable of producing a characteristic effect in the progress of the game.

However, in a drive mechanism using a gear mechanism, the movable platen surface parts are brought to the normal stop position due to backlash, dimensional tolerance of other parts, assembly errors, play due to aging, etc. There is a problem that it cannot be stopped, and the stop position varies and the position shifts.
That is, for example, a case is assumed in which a pair of door-shaped opening / closing members are disposed on the front surface of the liquid crystal display device so as to be freely opened and closed, and the opening / closing members are slidably opened and closed. When the two open / close members that were in the separated open positions are moved to the close position and stopped, the stepping motor is driven in the close direction and moved to a position where the inner edges of the open / close members abut against each other. Stop. By stopping the stepping motor, a static torque is applied, and the motor itself is locked in that state. Therefore, the opening / closing member that has reached the closing position should not return in the opening direction.

  However, in actuality, the opening / closing member has play (backlash) in the opening / closing direction due to dimensional tolerance (variation from the reference dimension) of various parts constituting the drive mechanism and other related parts and backlash. Yes. For this reason, the opening / closing member is released from the normal closing position (stop position) by the distance of the play by the reaction force when contacting the stopper member provided at the closing position or the rebounding force when contacting the opening / closing members. It may stop in the state of reverting to. For this reason, there has been a problem that the screen of the liquid crystal display device that cannot be seen by the player can be seen from the gap between the inner edges of the opening / closing member. Although measures are taken to switch the screen to a dark state so that there is no problem even if the screen of the liquid crystal display device can be seen from the gap between the opening and closing members, it is an effective measure because it causes the control program to become complicated is not.

Such a problem also occurs when the opening / closing member moves to the open position and stops, and the position that is biased in the closing direction by the amount of play from the normal open position due to the rebounding force at the stop position. Therefore, the bag opening / closing member originally retracted from the player's field of view is viewed.
Such a problem occurs in the same manner even when the gear is not used as a drive mechanism. For example, even when a wire or pulley is used as the drive mechanism, the opening / closing member may not be able to be stopped at the normal stop position due to dimensional tolerances, assembly errors, deterioration with time, and the like of each component.
As described above, conventionally, in a movable platen surface component that is driven to advance and retreat on a predetermined movement path by a drive mechanism using a gear, a motor is used to stop the movable platen surface component being moved at a regular stop position. Even when the vehicle is stopped, there is a problem in that it returns backward and stops at a position deviated from the normal stop position due to rebound force at the stop position and play of related parts such as the drive mechanism.
In particular, in a door-like opening and closing member arranged in front of a display device or the like, the inner edges are separated from each other by stopping at a position deviated from the normal closing position to the opening direction. The LCD screen was visible to the player.

In FIG. 1, the gaming machine 1 includes an outer frame 300 that is attached to an island facility of a game store, and a glass frame 310 that is rotatably supported by the outer frame 300 on one vertical side. The outer frame 300 is provided with a game board 2 in which a game area 3 in which game balls flow down is formed. The glass frame 310 supports a glass plate (not shown) that covers the game area 3 so as to be visible in front of the game board 2 (on the player side).

In addition, the glass frame 310 has an operation handle 311 for launching a game ball toward the game area 3 by being rotated, an audio output device (speaker) 312, and upper and lower effect lights having a plurality of lamps. Devices 313a and 313b, an effect button 314 for changing the effect mode by a pressing operation, and left and right effect movable illumination devices 320L and 320R are provided.
A tray unit 315 is provided below the glass frame 310. The tray unit 315 is provided with a ball tray portion that stores a plurality of game balls. The ball tray portion has a downward inclination so that the game balls flow down toward the operation handle 311. . Then, when the player rotates the operation handle 311, the game ball is launched into the game area 3.
When the game ball launched as described above rises between the rails 5a and 5b and exceeds the ball return prevention piece 5c, it reaches the game area 3 and then falls in the game area 3. At this time, the game ball falls unpredictably by a plurality of nails and windmills provided in the game area 3.

Next, the configuration of the game area 3 of the game board 2 will be described.
The game area 3 is provided with a plurality of general winning ports 18. When a game ball wins each of these general winning ports 18, a predetermined prize ball (for example, 10 game balls) is paid out.
In addition, a first start port 13 and a second start port 14 that constitute a start region into which a game ball can enter are provided in a region below the center of the game region 3.
The second start port 14 has an open / close door 14b, and is movable and controlled to a first mode in which the open / close door 14b is maintained in a closed state and a second mode in which the open / close door 14b is in an open state. The Therefore, when the second start port 14 is in the first mode, there is no opportunity for winning a game ball, and when it is in the second mode, the chance for winning a game ball is increased.

The big prize device 16 is normally kept in a closed state with the first big prize opening by a big prize device movable piece (first opening / closing piece) 16b, so that it is impossible to enter a game ball. On the other hand, when a predetermined special game is started, the first opening / closing piece 16b is opened, and the first opening / closing piece 16b functions as a saucer for guiding the game ball into the first big prize opening. Will be able to enter the first grand prize opening. When a game ball enters the first grand prize opening, a predetermined prize ball (for example, 15 game balls) is paid out.
Furthermore, in order to discharge the game balls that have not entered any of the general winning opening 18, the first starting opening 13, the second starting opening 14, and the big winning device 16 into the lowermost area of the gaming area 3. Out port 19 is provided.

In addition, an opening 3A is formed at the center of the game area 3, and a decorative member 6 that affects the flow of the game ball is provided along the periphery of the opening 3A. An image display device (display device) 7 composed of a liquid crystal display device or the like is provided on the back surface (rear surface) side of the game board, which is a substantially central portion (open portion) of the decorative member 6.
The image display device 7 displays an image during standby when no game is being performed, or displays an image according to the progress of the game. Among them, three effect symbols 8 for informing the result of the jackpot lottery to be described later are displayed, and a combination of specific effect symbols 8 (for example, 777) is stopped and displayed as a jackpot lottery result. Is notified.
Specifically, when a game ball enters the first start port 13 or the second start port 14, the three effect symbols 8 are scroll-displayed, and the scroll is stopped after a predetermined time has elapsed. The symbol 8 is stopped and displayed. Further, by displaying various images, characters, and the like during the variation display of the effect symbol 8, a high expectation that the player may win a big hit is given to the player.

The moving members (moving parts) 60 and 70 disposed in front of the image display device are opened and closed in a substantially horizontal direction, and give the player a sense of expectation depending on the operation mode. In addition, liquid crystal display devices (sub liquid crystal display devices) 62 and 72 are mounted on each moving member, and an image is displayed there. Various combinations of feelings of expectation are given to the player by combining the change of the movement mode of the moving member and the video effect by the liquid crystal display device.
Furthermore, in addition to the above-mentioned various effects devices, the audio output device 312 outputs BGM (background music), SE (sound effects), etc., and performs effects by sound. The effect lighting devices 313a and 313b are The lighting direction and the emission color of each lamp are changed to produce an effect by illumination.

<Description of Embodiment of Movable Plate Surface Parts>
Next, FIG. 3 is a perspective view showing a state in which the game board unit and the glass frame are assembled to the outer frame so as to be freely opened and closed, and FIG. 4 is a state in which the game board, the movable board surface parts, and the base frame are separated. 5 is an exploded perspective view of the front side of the movable platen surface part, and FIG. 6 is an exploded perspective view of the front side of the moving member, guide unit, and drive mechanism constituting the movable platen part. It is.
As shown in FIG. 3, a game board unit U and a glass frame 310 are assembled to the outer frame 300 so as to be freely opened and closed.
The game board unit U has a configuration in which a base frame 30 and an image display unit are assembled on the back of the game board 2.
As shown in FIG. 3, FIG. 4, etc., a base frame (liquid crystal base frame) 30 having an opening 30 a penetrating in the front-rear direction (the thickness direction of the display device ) on the back surface (rear surface) of the game board 2. Is assembled, and an image display unit (image display device and image display cover) (not shown) is assembled on the back side (rear side) of the base frame so as to close the opening 30a.

  The movable platen surface component 40 in the pachinko gaming machine according to the present invention is closed by causing each inner edge to contact (or approach) while being slidably guided by the guide portion 50 with the inner edges 60a, 70a facing each other. A pair of moving members (moving portions) 60 and 70 that move back and forth in a substantially horizontal direction between a position (approaching position) and a separated open position (separating position), and a suitable position of each moving member, in this example, supports the lower part Two drive mechanisms M that open and close in a closing direction that approaches each other and an opening direction that separates them, and a stop positioning device (stop positioning unit) 90 that reliably stops each moving member at an arbitrary stop position. .

The stop positioning device (stop positioning unit) 90 varies when the moving members 60 and 70 that are driven to open and close by the drive mechanisms M reach the closed position (closed stop position) and the open position (open stop position), respectively. It is a means for determining the stop position so that it can stop at the normal closed position and the open position.
That is, since each drive mechanism M includes a plurality of gears, each moving member is brought into a normal closed position or an open position due to backlash between gear crests of each gear and dimensional tolerance of other drive parts. It stops at a position that is deviated in the opening direction or the closing direction by the amount of backlash from the normal closing position or the opening position. This is the cause of giving the player the impression that the operation performance of the movable surface parts is low. In addition to the backlash between the gears, the moving member inherently has play in its opening / closing operation direction due to dimensional tolerances of parts constituting the drive mechanism and other related parts, assembly accuracy errors, aging deterioration, etc. Therefore, it may not be able to stop correctly at the stop position due to play.

Hereinafter, the movable surface parts in the gaming machine of the present invention will be described in more detail.
As shown in FIGS. 1 to 5, the movable board surface component 40 has a base member 41 as a fixed member fixed to the game board 3 and the like, and a lower portion guided by a guide portion 50 provided on the base member 41 in the horizontal direction. A pair of left and right moving members (moving portions) 60, 70 as movable members that move, rack gear members 61, 71 fixed horizontally to the lower portions of the moving members 60, 70, and rack gear portions 61a of the rack gear members, A pinion gear (drive transmission unit) 80c that moves the moving members 60 and 70 forward and backward in the opening direction and the closing direction by rotating in mesh with the 71a, a motor 81 that drives each rack gear member, and a driving force from the motor Are transmitted to the pinion gear 80c (drive transmission units) 80a and 80b. The transmission gear 80 a is also an output gear integrated with the output shaft of the motor 81.

The inner edges 60a, 70a of the moving members 60, 70 extend in a straight line in the vertical direction, and when the moving members are in the closed position as shown in FIG. It is configured to form a slight gap within an allowable range such that a gap is not formed by contact or proximity over the area, or the back cannot be visually recognized.
Of course, the inner edge of the moving member does not have to be a vertical straight line, and can take various forms.
As shown in FIGS. 4, 5, 6, and the like, the guide portion 50 includes two left and right guide rails 51 and 52 extending in the horizontal direction, and the two guide rails have an inner end portion positioned on a positioning member (positioning portion). ) Are connected by a connecting member that also serves as 42. Each moving member may be guided by a single long guide rail.

The moving members (moving portions) 60 and 70 are supported by the guide rails 51 and 52 so as to be able to advance and retract in the horizontal direction. For example, the guide rails 51 and 52 are configured to be engaged with guided portions (guide holes) 61b and 71b provided in the rack gear members 61 and 71 so as to be slidable in the horizontal direction and not to be dropped off. .
The drive mechanism M for opening and closing the moving members 60 and 70 includes a pinion gear (transmission gear) 80c, transmission gears 80a and 80b, and motors (stepping motor, brushless DC motor, torque motor, AC servo motor, DC motor). Etc.) 81 and control means (not shown) for controlling the motor.
The stepping motor, the brushless DC motor, the torque motor, and the AC servo motor can obtain a static torque not only during energization (excitation) but also during deenergization (non-excitation) as is well known. In particular, when the supply of the pulse is stopped, the generation of the driving force can be stopped accurately at that time, so that accurate rotation angle control can be performed.
The moving members 60 and 70 according to this example include small liquid crystal display devices (sub liquid crystal display devices) 62 and 72, and rack gear members 61 and 71 fixed to the lower part of the small liquid crystal devices.

FIGS. 7A and 7B are a front view and a rear view of the open state in which each moving member is stopped at the most spaced position, and FIGS. 8A and 8B are just before the moving member reaches the closed position. FIG. 9A and FIG. 9B are a front view and a rear view in a closed state in which each moving member has moved to the innermost side (approaching position).
10 is a front view showing the state of the driving mechanism and the stop positioning device when the moving members are separated from each other. FIG. 11 is a driving mechanism when the moving member is in a state immediately before the closing position. FIG. 12 is a front view showing the state of the stop positioning device, and FIG. 12 is a front view showing the state of the drive mechanism and the stop positioning device when the moving member is in the closed state. 13 (a) and 13 (b) are a plan view transverse sectional view showing a state of the elastic biasing member corresponding to the separated state of FIG. 10, and a front view showing a meshed state of the rack gear member and the pinion gear. 14 (a) and 14 (b) are a plan view transverse sectional view showing the state of the elastic biasing member corresponding to the state of FIG. 11, and a front view showing the meshing state of the rack gear member and the pinion gear. 15 (a) and 15 (b) are a plan view transverse sectional view showing a state of the elastic biasing member corresponding to the closed state of FIG. 12, and a front view showing a meshed state of the rack gear member and the pinion gear.
The control means controls the motor 81 to rotationally drive the transmission gears 80a, 80b, and 80c in the forward rotation direction (in the closing direction), thereby moving the moving members 60 and 70 in the closing direction via the rack gear members 61 and 71. Move. In order to move each moving member in the opening direction, the control means controls the motor 81 to rotate the transmission gears 80a, 80b, 80c in the reverse direction (in the opening direction), thereby rotating the moving gears via the rack gear members 61, 71. The moving members 60 and 70 are moved in the opening direction.

A characteristic configuration of the gaming machine according to the present invention includes a moving unit that moves toward a stop position, a driving unit (motor) that generates driving force, and the driving force of the driving unit to the moving unit (rack gear member). A driving force transmission unit (transmission gear) for transmitting, and a stop positioning device (stop positioning unit) 90 for stopping the moving unit at a stop position, the stop positioning device being before the predetermined part of the moving unit reaches the stop position Alternatively, after reaching the stop position, there is an elastic biasing member (biasing part) 100 that biases the moving part in a direction different from the moving direction to the stop position.
That is, the gaming machine of the present invention moves (moves in one direction or reciprocates) along a predetermined track (movement path), and stops at a stop position provided on the track during movement in at least one direction. At least one moving member (moving unit) 60, 70, a stop positioning device 90 for determining the stop position of the moving member, a motor (driving unit) 81 for moving the moving member, and each movement from the motor And a driving mechanism M including transmission gears (driving force transmitting portions) 80a, 80b, and 80c that transmit the driving force to the members.

A characteristic configuration of the stop positioning device 90 is that the predetermined position of the moving member (for example, the front end portion in the moving direction) reaches the stop position (or after the stop position), the moving member is defined as the one direction. An elastic biasing member 100 that elastically biases (starts elastic biasing) in different directions (including the reverse direction, the return direction, and other directions) is provided. As the elastic biasing member 100, any elastic member such as a coil spring, a leaf spring, a compression spring, a tension spring, rubber, an elastic resin, or the like can be used.
As shown in FIGS. 10 to 15, in this example, each elastic biasing member 100 made of a coil spring is disposed so as to be movable relative to the outer periphery of each guide rail 51, 52 in the axial direction. Thus, the moving members 60 and 70 are configured to move along the guide rail. Each elastic urging member includes a coil spring (elastic member) 101 that is supported by a part of each moving member and holds a cylindrical contact piece 102 at the other part. The contact piece 102 compresses and deforms the coil spring 101 by abutting (pressing contact) with the positioning member 42 disposed at the closed stop position (on the movement path), and the moving member is moved in a direction different from the moving direction so far ( A force that pushes in a different direction is generated. The coil spring 101 is not necessarily arranged on the outer periphery of the guide rail, and may be arranged anywhere near the inner end of each moving member.

Further, when the elastic urging member 100 is provided in the vicinity of the distal end portion in the moving direction of the moving member, the distal end portion of the elastic urging member (the distal end portion of the contact piece 102) is moved in the opened state of the moving member shown in FIG. It is not always necessary to protrude the moving direction (closing direction) ahead of the tip edge of the member. Even if the tip of the elastic urging member in the open state is placed outside the inner edge of the moving member (in the opening direction), the contact portion of the positioning member is outside the tip of the moving member when closed. This is because it may be configured to enter.
Next, the stop positioning device 90 has predetermined portions of the moving members 60 and 70, in this example, the front end portion in the moving direction (the left end portion when moving in the closing direction and the right end portion when moving in the opening direction) as shown in FIG. The elastic biasing member 100 is actuated immediately before reaching the normal closed position (closed stop position) or before the normal open position (open stop position) shown in FIG. 7 (or after reaching the open position). By energizing each moving member in a direction opposite to the previous moving direction (other different directions), the gear portions (rack gear portions 61a, 71a) of the driven gear members (rack gear members 61, 71) are moved. Reverse the rotation (reverse), and return the rotation angle of the driving gear member (pinion gear 80c), which is the mating counterpart, to the limit of the movable range due to the play of the moving member, and rotate in the return direction beyond the limit angle A means for holding its state without come.

  The moving member usually has play (backlash) along the moving direction due to dimensional tolerances of parts constituting the drive mechanism or the like, and this play is a rebound (reaction force) when the moving member stops. This causes variations in the stop position, and causes a stop at the regular stop position.

  In this embodiment, before the stop position (or after reaching the stop position), the elastic urging member 100 moves in a direction different from the previous movement direction (in the reverse direction in this example) by the return action of the elastic biasing member 100. By pressing the member (rack gear member), the pinion gear 80c that drives the moving member is pressed to reverse the amount of play and the state is maintained. The pinion gear is in a state where it is pressed by the rack gear member until it reaches a limit state where it cannot be rotated further in the return direction, and the play of the moving member due to play is eliminated. In this play free state, the gear crests of the rack gear members 61a and 71a that are driven gear members and the gear crest of the pinion gear 80c that is the drive side gear member are kept in contact with each other, and are not separated. Even if force in the return direction is further applied to the member, the pinion gear cannot be rotated further in the return direction. In this state, when the pinion gear is rotated in the original movement direction (direction toward the stop position), the moving member can move toward the stop position without play, and transmission of driving force from the pinion gear can be performed. When the motor stops, the motor can be stopped reliably (without return due to play) at the stop position by the stationary torque of the motor.

  It is to be noted that the backlash caused by play is eliminated when the elastic biasing member 100 biases and returns each moving member in the direction opposite to the moving direction so far, and the rack gear portions 61a and 71a of the rack gear member. Not only between the pinion gear 80 c and the pinion gear 80 c but also between the pinion gear 80 c and the transmission gear 80 b, and between the transmission gear 80 b and the transmission gear 80 a, rattling due to play (addition beyond the limit position). The possibility of reversing is also eliminated. That is, the elastic urging member can reverse the drive-side gear crest by the driven-side gear crest at the meshing portions of all the gears included in the drive mechanism. In other words, the play amount of the moving member that is eliminated by the elastic biasing member is the total play amount obtained by accumulating the amount of play caused by backlash between all the gears constituting the drive mechanism and others (the moving member is at the stop position). This corresponds to all play amounts that cause a reversal).

The control means continues to drive the motor 81 in the closing direction or the opening direction until the sensor S detects that the moving member has reached the stop position. Thus, the gear members 61, 71, 80a, 80b, and 80c are continuously driven until the moving members 60 and 70 reach the closed stop position or the open stop position against the biasing force of the elastic biasing member. When the sensor S detects that each moving member has reached the closing stop position or the opening stop position, the motor is stopped.
As a result, the moving member is closed at the closed stop position and opened by play of the moving member due to backlash between gear crests, component tolerance, etc., and the return of the moving member due to bounce when the moving member reaches the stop position. The problem of being unable to stop correctly at the stop position can be solved.
As the sensor S, any means such as a photo interrupter or a limit switch can be used. For example, a sensor made of a photo interrupter is arranged on the base member 41 so that when the moving member reaches a normal stop position, a detection piece provided on the moving member is detected by the sensor.

The stop positioning device 90 of the present invention is not limited to the variation in the stop position of the moving member due to backlash between the gear members constituting the drive mechanism, but the accuracy error of other parts constituting the drive mechanism, etc. The variation (play) of the stop position of the moving member caused by an assembly accuracy error, deterioration, or the like can be eliminated by cooperation with the motor, and the moving member can be accurately stopped at the stop position.
By setting the urging force of the elastic urging member 100 to be weaker than the driving force (static torque) from the motor 81, the opening / closing position as described above can be positioned. That is, the spring pressure of the elastic biasing member is set to be smaller than the static torque of the motor.

<Operation of drive mechanism, stop positioning device, etc.>
The stop positioning device 90 having the above configuration and the movable platen part 40 having the drive mechanism M operate as follows.
First, in the open state of the moving member shown in FIGS. 10 and 13, when the motor 81 starts driving in the closing direction, the gear crest of each pinion gear 80c that is a driving side gear is a rack gear that is a driven side gear. The rack gears 61a and 71a of the members rotate in the closing direction prior to the rack gears 61a and 71a. For this reason, as shown in detail views A and D of the main part in FIG. 10 and FIG. 13A, the gear crests of the pinion gears 80c move the rack gear parts 61a and 71a of the rack gear members in the closing direction (inward in the moving direction). By pressing, each moving member integrated with each rack gear member moves in the closing direction, and the inner edges 60a and 70a of each moving member approach each other.
When the motor 81 starts to rotate in the closing direction, as shown in each of the main part detailed views B, C, E, and F in FIG. 10, similarly, the meshing part between the transmission gears 80 a, 80 b, and 80 c is driven similarly. The gear crest of the side gear presses the gear crest of the driven gear in the closing direction.
At this time, each elastic biasing member 100 is in the most inoperative state as shown in FIG. 10A and FIG. 13A, and the tip end of each contact piece 102 is It is not in contact with any other member.

  In this embodiment, the elastic urging members 100 provided in the vicinity of the inner edges 60a and 70a of the respective moving members are in contact with the positioning member 42 provided at the same position when reaching the position immediately before the closing stop position. The elastic force is exerted by compressing and deforming, and each moving member is urged to return in a direction different from the moving direction so far.

  11 and 14 show a state immediately before both moving members reach the closing stop position. At this stage, each elastic biasing member 100 has already started to come into contact with the positioning member 42 and is compressed (see G in FIG. 11). In the state and FIG. 14 (a)), each moving member 60, 70 is started to be urged in the opening direction. For this reason, as shown in a detailed diagram A of the main part in FIG. 11, the rack gear portions 61a and 71a of the rack gear members 61 and 71, which are driven gear members, are starting to be urged in the opening direction. The pinion gear 80c is urged in the opening direction in contact with the gear crest of the pinion gear 80c. For this reason, the rack gear portion and the pinion gear can be kept in pressure contact with each other, and the pinion gear is fully rotated in the opening direction within the range of play, and is further rotated in the opening direction. It cannot be moved.

When the elastic urging member 100 urges the moving member in the opening direction, as shown in detail drawings B, C, E, and F of each main part in FIG. 11, the other transmission gears 80b and 80c are engaged with each other. Similarly, the driven gear portion is in a pressure contact state in which the driving gear portion is pressed in the opening direction to the limit within the range of play, and the driven gear cannot rotate further in the opening direction. It has become.
Note that, regardless of whether or not the other transmission gears 80b and 80c are reversely driven to the limit in the opening direction, if the pinion gear 80c is reversely rotated to the limit angle by the rack gear member, The play cancellation function by cooperation with the motor can be exhibited.
At this time, the contact piece 102 of each elastic urging member 100 is more than the most stretched state by contacting the positioning member 42 as shown in the detail view G of FIG. 11 and FIG. 14A. In a compressed state, the movable members 60 and 70 (rack gear members 61 and 71) are biased in the opening direction (or in a state where biasing has started).
At this time, the motor 81 does not stop driving, but continues to drive in the direction of closing the moving member.

Even after the transition to the state of FIG. 11, the motor 81 is continuously driven in the closing direction, so that the pinion gears 80c as drive side gears remain in contact with the rack gear portions 61a and 71a shown in FIG. Continue to rotate in the closing direction. Since the pinion gear 80c is in a limit position (a state in which play is eliminated) in which the pinion gear 80c cannot further rotate in the opening direction, the pinion gear 80c rotates after the pinion gear starts to rotate in the closing direction. When stopped (the state of FIGS. 12 and 15), the stopped angle is maintained and it does not rotate in the opening direction.
That is, as shown in FIGS. 12 and 15, the inner end edges 60a and 70a of the respective moving members have reached the closing stop position, or have come into contact (or close proximity to contact). When the motor 81 that has received the detected signal from the sensor S stops driving, both moving members can be stopped at the closed stop position as shown in FIG. Since the motor 81 stops driving and the rotation of its output shaft is fixed by the static torque, any of the gears 80a, 80b, 80c (particularly the pinion gear 80c) cannot rotate in either forward or reverse direction. Then, the driven-side gear meshing with the driving-side gear is stopped in a state where it is pressed in the closing direction. Therefore, there is no room for the rack gear member to move in the opening direction by the distance of play of the moving member due to the reaction force when the moving member stops.

12A and 12B and FIG. 15B show the state of the meshing portion of each gear at this point.
At this time, each contact piece 102 is in a state where the elastic urging member is compressed most by coming into contact with the positioning member 42 as shown in detail G of FIG. 12 and FIG. 15A. At this time, the moving members 60 and 70 (rack gear members 61 and 71) are stopped at the closed stop position in a state where play is eliminated, and the inner end edges 60a and 70a are kept in contact or in proximity. Can do.

<Embodiment when stopping the moving member at the open stop position>
In the above-described embodiment, the configuration example is shown in which the stop position of the two moving members that are opened and closed by the stop positioning device 90 is determined so that there is no deviation due to play. However, the stop positioning device of the present invention moves along a predetermined trajectory. In general, the present invention can be applied to a case where the moving member to be stopped is accurately stopped at an arbitrary stop position without being displaced due to play.
Therefore, for example, when the moving member is stopped at the open stop position shown in FIG. 7, the stop positioning device 90 can be used. In this case, as shown in FIG. 7, the elastic urging member 100 constituting the stop positioning device is provided outside the moving members 60 and 70, and the elastic urging member is arranged at the open stop position. The movable member (rack gear member) may be compressed by contact with the movable member and returned to the closing direction by a distance of play of the movable member.
As the moving member returns to the closing direction by the amount of play in the opening and closing movement direction, the rack gear portions 61a and 71a of the rack gear members 61 and 71 press the gear portion of the pinion gear 80c in the closing direction, and further in the closing direction. Set to the limit state where it cannot rotate. By continuing to drive the motor in the opening direction in this state, it is possible to move the outer end of the moving member to the normal opening stop position, and further, due to play by stopping the motor after moving to the opening stop position. It is possible to eliminate the variation in the stopped position, stop the moving member at the open stop position, and maintain the state.

FIGS. 16 to 22 show configuration examples when the stop positioning device 90 is arranged on the opening stop position side of the moving member, and FIGS. 23 to 25 are explanatory views showing a procedure for stopping the moving member at the opening stop position. is there.
16A and 16B are perspective views showing the configuration of the stop positioning device provided on the open stop position side of the left moving member 60, and the stop provided on the open stop position side of the right moving member 70. FIGS. 17A and 17B are an exploded perspective view showing a configuration of a left stop positioning device, and an exploded perspective view showing a configuration of a right stop positioning device. 18 is an enlarged perspective view showing the configuration of the left stop positioning device, FIG. 19 is an enlarged front view showing the configuration of the left stop positioning device, and FIG. 20 is an enlarged perspective view showing the configuration of the right stop positioning device. FIG. 21 is an enlarged front view showing the configuration of the right stop positioning device, and FIG. 22 is a front longitudinal sectional view of FIG.

The left stop positioning device 90L shown in FIGS. 16 (a), 17 (a), 18 and 19 includes an elastic biasing member 100 supported by an attachment member 110 fixed to the base member 41. Yes. The elastic urging member includes a coil spring (elastic member) 101 and a cylindrical contact piece 102 disposed at the end of the elastic member. The contact piece 102 contacts the appropriate position of the moving member 60 that moves to the open stop position on the outer side (left side) along the guide rail 51 so that the coil spring 101 can be compressed and deformed. It is arranged at a position along the movement path (position where it can come into contact with the moving member). In this example, the coil spring 101 and the contact piece 102 are disposed above the guide rail 51 in parallel with the guide rail. Reference numeral 115 denotes a bracket provided with a guide cylinder 115a that fixes the end of the guide rail 51 to the mounting member 110 and guides the contact piece 102 so as to advance and retreat in the axial direction. The bracket 115 is fixed to the mounting member 110 with screws.
The sensor S fixed to the mounting member 110 is, for example, a photo interrupter, and a light emitting sensor and a light receiving sensor are disposed to face each other in a groove in the drawing. The outer edge of the moving member 60 has a detection piece that enters the groove of the sensor, and when the moving member reaches the opening stop position, the detection piece enters the groove of the sensor, thereby opening the stop position. Is detected, and a detection signal is output to the control means.

  The right stop positioning device 90R shown in FIGS. 16B, 17B, 20, 21, and 22 is supported by an elastic member 100 that is supported by a mounting member 120 that is fixed to the base member 41. It has. The elastic urging member includes a coil spring (elastic member) 101 and a cylindrical contact piece 102 disposed at an end of the elastic urging member. The contact piece 102 contacts the appropriate position of the moving member 70 that moves to the open stop position on the outer side (right side) along the guide rail 52 so that the coil spring 101 can be compressed and deformed. It is arranged at a position along the movement path. In this example, the coil spring 101 and the contact piece 102 are disposed below the guide rail 52 in parallel with the guide rail. Reference numeral 125 denotes a bracket provided with a guide cylinder 125a for fixing the end of the guide rail 52 to the mounting member 120 and guiding the contact piece 102 so as to advance and retreat in the axial direction. The bracket 125 is fixed to the mounting member 120 with screws.

As shown in the cross-sectional view of FIG. 22, the coil spring 101 is disposed in the cylindrical contact piece 102, and the contact piece can be stably advanced and retracted in the axial direction by the guide cylinder 125a.
The sensor S fixed to the attachment member 120 is, for example, a photo interrupter, and has the same configuration as the sensor S of FIG. The outer edge of the moving member 70 has a detecting piece that enters the groove of the sensor, and when the moving member reaches the opening stop position, the detecting piece enters the groove of the sensor so that the opening stop position is reached. Is detected, and a detection signal is output to the control means.

FIG. 23 is an overall front view showing a state in which each moving member is moving toward the opening stop position, and FIG. 24 is a diagram showing a play between components by the elastic biasing member immediately before the moving member is in the opening stop position. FIG. 25 is an overall front view showing a state in which the movement member is returned in the closing direction by FIG. 25, and FIG. 25 shows a state in which the moving member is correctly stopped at the open stop position by stopping the motor (drive unit). It is a whole front view.
In the stage of FIG. 23, the transmission gears 80a, 80b, 80c are rotated in the opening direction indicated by the arrows by driving the motor 81 in the opening direction, and accordingly, the moving members integral with the rack gear members 61, 71 are rotated. 60 and 70 also move in the opening direction. At this time, the elastic biasing member 100 is in an inoperative state.

Next, in the stage of FIG. 24, the coil spring (elastic member) 101 constituting each elastic urging member 100 is compressed and deformed by coming into contact with the moving members 60 and 70, and exhibits elasticity in the closing direction. ing. For this reason, each rack gear member 61, 71 urges each pinion gear 80c to push back in the closing direction. Since each moving member has play (backlash) in the moving direction due to dimensional tolerances of the drive mechanism and other related parts, the pinion gear 80c (and other transmission gears) is equivalent to this play. Then, it is pushed back in the closing direction opposite to the moving direction so far and reverses. When the rotation angle of the pinion gear 80c reaches a limit position where it cannot be reversed any more, the rack of the rack gear member and the pinion gear maintain the contact in this state.
During this time, since the driving force from the motor in the opening direction is transmitted to the pinion gear, when the limit position is reached, transmission of the driving force from the pinion gear to the rack gear member is resumed, and the moving member becomes normal. Move until reaching the open stop position. When each sensor S detects that each moving member has reached the open stop position, the control means stops the motor 81 based on the detection signal from the sensor. As a result, the moving member accurately stops at the open stop position without variation, and this stopped state can be maintained (FIG. 25).

<Other embodiments>
Depending on how the urging force of the elastic urging member 100 is set (strong or weak), or depending on the speed at which the motor moves the moving member to each stop position, the moving-side tip of the moving member reaches the normal stop position. Thus, the moving member may return in the opposite direction to the previous moving direction by the amount of play due to the biasing force of the elastic biasing member. In other words, the elastic biasing member cannot reverse the moving member before the moving-side tip of the moving member reaches the normal stop position, and returns the moving member after it reaches the normal stop position. Sometimes.

Also in this case, by continuing to move the moving member in the original moving direction by the motor 81, when the normal stop position is reached again from the reverse position, the normal member is detected based on the signal from the sensor that has detected this. If the motor is controlled to stop at the stop position, it can be accurately stopped at the stop position by the stationary torque of the motor. Assuming such a case, the motor is not stopped when the first detection signal is output when the moving member is first detected by the sensor, and the motor is not stopped within a predetermined time from the first detection signal. Control is performed to stop the motor when the detection signal of the second time is output from the sensor. In this case, after the first detection signal is output, control is performed to stop the motor when the second detection signal is not output within a predetermined time.
This will be further explained. When the urging force of the elastic urging member 100 is too small compared to the momentum when the moving member reaches the closing stop position, the elastic urging member returns the rack gear members 61 and 71 in the opening direction. Before the operation, the inner edge (predetermined part) of the moving member may reach the closed stop position. In this case, after the moving member reaches the closing stop position, the elastic urging member urges the rack gear members 61 and 71 to return in the opening direction by the backlash caused by the play of the moving member. For this reason, the pinion gear 80c is also rotated in the opening direction by the amount of play, and can no longer be rotated in the opening direction. In this case, after reaching the closing stop position once, the moving member moves from the closing stop position to the opening direction for a short time, but immediately returns to the closing stop position by the driving force from the motor 81 and is in the closed state. Therefore, there is no problem by setting the time for the moving member to return in the opening direction to a short time (for an instant) that the player cannot visually recognize.

An elastic biasing member may be provided on both the moving member side and the base member side.
Moreover, in each said embodiment, although one elastic biasing member was provided in order to stop and position each moving member, several elastic biasing members are provided in the different location of each moving member, or the different location of a base member. May be provided.

<Other embodiments>
In the embodiment shown in FIGS. 4 to 15, the elastic biasing member 100 is provided on the moving member side and brought into contact with the positioning member (positioning portion) 42 provided on the base member 41 side to be compressed and deformed. The elastic urging member is provided on the moving path (in this example, the positioning member 42 (base member 41)) side, and the elastic urging member is provided on the elastic urging member. When the moving member comes into contact, it is compressed and deformed, and the moving member is pushed back in the direction different from the previous moving direction (for example, the reverse direction) by the amount of play formed by backlash and dimensional tolerance of each part. You may comprise as follows.
When the elastic biasing member is provided at the front end of the moving member in the moving direction, the positioning member 42 in contact with the elastic biasing member is disposed at the center of the moving path as shown in FIGS. However, when the elastic biasing member is disposed at a part other than the front end of the moving member in the moving direction, for example, at the intermediate part in the moving direction or at the rear part in the moving direction, the positioning member 42 is not the central part of the moving path but each elastic It arrange | positions in the other position which can contact a biasing member and can compress-deform this.

Even when the elastic urging member is arranged on the moving path instead of the moving member side, the elastic urging member comes into contact with the tip in the moving direction of the moving member and compresses the moving member when the moving member stops. It is not necessary to have a configuration for biasing in the return direction. That is, a contact portion with the elastic biasing member is provided at a location other than the front end portion in the moving direction of the moving member, for example, an intermediate portion in the moving direction and a rear end portion in the moving direction, and when the moving member approaches the stop position, You may comprise so that a moving member may be urged | biased in a return direction by a contact part and an elastic urging | biasing member contacting.
That is, when the elastic urging member 100 is not provided on the moving member side, that is, when the elastic urging member is provided on the moving path, the moving member side is positioned before or after the moving member reaches the stop position. The elastic urging member may contact any part of the moving member as long as the urging force in the returning direction can be generated by contact.

<Structure and operation explanatory diagram of stop positioning device according to another embodiment>
Next, in FIGS. 26A and 26B, the elastic biasing member 100 is provided only on one moving member 60 without providing the positioning member 42 on the base portion 41 side, and this elastic biasing member is moved on the other side. By making contact with the inner edge of the member 70 and other parts, the two moving members are released by one elastic biasing member by the amount of play formed by the dimensional tolerances of the parts constituting the drive mechanism M, etc. In this configuration example, the moving member is stopped at the closing stop position without shifting the stopping position by returning to the closing stop position in this state. The locking control for moving the moving member to the closing stop position by the motor 81 and stopping the motor in this state after both moving members return to the opening direction by the elastic biasing member is the same as in the above embodiment.
Each moving member is provided with an elastic urging member, and when the moving member is closed, the elastic urging member provided on one moving member is brought into contact with the other moving member so as to ensure the elastic force in the opening direction. It may be.
Thus, without providing a positioning member for compressing and deforming the elastic urging member at the stop position, the elastic urging member 100 is provided only at an appropriate position of one moving member 60, for example, the front end in the moving direction. You may comprise so that an elastic biasing member may be compressed and deformed by making it contact with the appropriate position (non-elastic member) of the other moving member 70. In this case, not only the moving member 60 but also the other moving member 70 is opened by the amount of play of the parts constituting the drive mechanism by one elastic biasing member 100 provided on one moving member 60. It is possible to exhibit the function of returning to the state and continuing to maintain the state.

<Structure and operation explanatory diagram of stop positioning device according to another embodiment>
Next, in FIGS. 27A and 27B, without providing the positioning member 42, the distal end portions of the elastic urging members 100 provided in the vicinity of the inner edges of the respective moving members 60 and 70 are moved to each other. By abutting at the time of closing and compressing both, the two moving members are returned to the opening direction by the amount of play formed by the dimensional tolerances of the parts constituting the driving mechanism M, and in this state, the closing stop position is reached. A configuration example is shown in which the moving member is stopped at the closed stop position without being shifted by the stop position. The locking control for moving the moving member to the closing stop position by the motor 81 and stopping the motor in this state after both moving members return to the opening direction by the elastic biasing member is the same as in the above embodiment.
Thus, the elastic urging members 100 are provided at the positions where the inner edges of the two moving members 60 and 70 are opposed to each other, and the respective elastic urging members come into contact with each other when the moving members reach the closed position. You may comprise so that each moving member may be returned in an open direction.
Alternatively, the elastic urging members 100 are provided at positions where the inner end portions of the two moving members 60 and 70 do not face each other, and each elastic urging member contacts the other moving member when each moving member reaches the closed position. Then, each moving member may be configured to return backward in the opening direction.

<Description of stop positioning method>
Next, according to the stop positioning device according to each of the above embodiments, the following stop positioning method of the moving unit can be realized.
That is, in the stop positioning method according to the present embodiment, the step of starting movement of at least one moving unit 60 (70) toward the stop position by the drive unit 81, and a predetermined part of the moving unit (for example, a tip in the moving direction) The urging unit 100 urges the moving unit in a direction (including the reverse direction) different from the moving direction up to that point, before or after reaching the stop position; The drive unit moves the moving unit to the stop position against the urging force by the step, and the drive source is stopped when a predetermined part of the moving unit reaches the stop position. is there.

<Structure and operation explanatory diagram of stop positioning device according to another embodiment>
In each of the embodiments described above, it is assumed that the moving member stops at the stop position and then returns to a different direction (reverse direction). However, in the movable platen part of the present invention, the moving member stops at the stop position. It can also be configured to continue to advance in the same direction after passing through the stop position. That is, the positioning member (positioning portion) 42 arranged at the stop position is configured to be able to advance and retreat from the movement path. When the positioning member 42 is positioned in the movement path, it comes into contact with the elastic biasing member provided on the movement member and compresses it. Let Further, when the positioning member is retracted from the moving path, the moving member can be passed in the same direction beyond the stop position.
When the elastic urging member is arranged on the moving member stop position or other movement path, the elastic urging member can be moved forward and backward from the movement path to move the moving member beyond the stop position. It is possible to move in the same direction.

When the urging member and the positioning unit are arranged at positions other than the moving member in this way, the urging member and the positioning unit are positioned on the moving path by configuring them so as to be retractable from the moving path of the moving member. When it is set, any position other than the end of the moving path can be set as the stop position. Further, when the urging member and the positioning part are retracted from the stop position on the movement path, the moving part can be moved beyond the stop position.
A drive source such as a solenoid or a motor can be used as a means for moving the positioning member and the elastic biasing member so as to move forward and backward from the movement path.

<Summary of actions and effects of gaming machine of the present invention>
In the gaming machine of the present invention described above, before or after the moving member (moving part) moving to the stop position reaches the stop position, the moving member is moved in a direction different from the previous moving direction (reverse direction). , A return direction and other directions). Due to the urging force of this urging member, the moving member moves in the opposite direction by the amount of play formed due to dimensional tolerances of drive transmission parts such as gears constituting the drive mechanism and other related parts, and other different directions. Move to. When the moving member returns in the reverse direction or the like, the drive transmission component positioned between the motor and the drive unit is reversed or moved in the reverse direction to the limit of the play amount. For this reason, the drive transmission component is driven in the normal direction in the original direction by the motor while maintaining the posture in which the drive transmission component can no longer reversely move in the reverse direction, and when the moving member reaches the stop position, it cannot be reversed due to play. . If the motor is stopped at this stage, the moving member can continue to maintain the position and posture at the moment when the motor is stopped by the stationary torque of the motor.

  The above operation will be described with respect to a configuration example in which the moving member is moved by a drive mechanism using a gear. The rack gear portion (driven gear portion) of the rack gear member fixed to the moving member meshes with the rack gear portion. The driven pinion gear (driven gear portion) is moved toward the stop position by forward rotation. Since the stationary positioning device is arranged so that the elastic urging member 100 operates when the moving member reaches the stop position or when the moving member reaches the stop position, the moving member is moved backward by the elastic urging member. Be energized by. Then, the gear crest of the rack gear portion tries to push back the gear crest of the pinion gear in the direction opposite to the forward rotation direction. When there is play between the rack gear portion and the pinion gear portion, the pinion gear rotates in the reverse direction by the limit of play by this biasing in the reverse direction, and cannot be reversed any further. The transition to the limit state where it cannot be reversed any more can be quickly achieved in a very short time by the biasing force from the elastic biasing member. As soon as the pinion gear reaches the reverse rotation limit state (limit angle), the pinion gear resumes normal rotation by the driving force in the normal rotation direction continuously transmitted from the motor. When the forward rotation of the pinion gear is resumed, the moving member integrated with the rack gear member continues to move toward the stop position, and when the stop position is reached, the motor is turned off and the moving member stops at the same time, and this stopped state is maintained. For this reason, the stop state can be maintained in a state in which the stop position of the predetermined part of the moving member is matched with the normal stop position on the moving path.

  The principle of the stop positioning device 90 of the present invention is not limited to the case where the moving member is moved by the gear mechanism, but when the moving member is moved by any kind of driving mechanism, the component tolerance, the assembly tolerance, and the deterioration with time. It is generally applicable when the moving member cannot be stopped at the normal stop position due to various causes such as loosening (when play is formed at the stop position of the moving member). Therefore, the drive transmission unit is not limited to a transmission mechanism using a gear mechanism. For example, even in a configuration in which the moving member is moved forward and backward using a wire wound and fed by a pulley, a spring for pulling out the wire, and a motor that drives the pulley and winds the wire, the play of the moving member is stopped at the stop position. Therefore, when the variation occurs, the stop positioning device of the present invention can be used.

Moreover, although the case where the two moving members open and close between the stop positions separated from each other and the close stop positions are illustrated in the above embodiment, the present invention is not limited to the number of moving members. The present invention can be applied to a movable platen surface component configured such that the moving member moves toward the stop position.
Further, the moving direction of the moving member is not limited to the horizontal direction, and the moving path of the moving member is not limited to linear motion. In short, the movement route and the movement direction may be any direction.

  For example, when it is desired to stop a moving member that makes a circular movement (one-way movement or two-way movement) along an endless moving path at a predetermined position on the moving path, an elastic biasing member (applied to the moving member side) By accurately compressing and deforming the urging portion) in contact with a positioning portion that is provided so as to be able to move in and out at the stop position (or fixedly arranged), it is possible to realize an accurate stop that eliminates variations in the stop position due to play. When the moving member is resumed to circulate in the same direction, the positioning member capable of advancing and retreating may be retracted from the moving path so as to pass the moving member. An elastic biasing member is disposed at a stop position on the movement path so that the elastic biasing member can freely move back and forth. When the movement member moves to the stop position, the elastic biasing member protrudes on the movement path and is compressed by contact with the movement member. You may make it deform | transform and urge in the direction (backward direction etc.) different from the moving direction so far, and you may make it stop without variation. In the case where the moving member resumes circulation in the same direction, the elastic urging member may be retracted from the moving path so as to pass the moving member.

Also, when the rotating body is rotated, if the stopping position varies due to play caused by the dimensional accuracy of the parts constituting the driving mechanism or the like, the stopping position can be reduced by applying the stop positioning device of the present invention. Variations can be eliminated. Also in this case, the elastic biasing member may be arranged on the moving member side, or the positioning part may be arranged on the moving path side of the moving member.
Further, in the above embodiment, a stepping motor, a brushless DC motor, a torque motor, an AC servo motor, etc. excellent in static torque are exemplified as motors (driving units) used in the driving mechanism. However, when a normal DC motor is used Even so, a static torque can be obtained by performing excitation at the time of stopping. For this reason, there is no restriction | limiting in the range of the motor which can be used.

Furthermore, the main configurations, operations, and effects according to the present invention are summarized as follows.
A gaming machine according to a first aspect of the present invention includes a moving unit that moves toward a stop position, a driving unit, a driving force transmitting unit that transmits a driving force of the driving unit to the moving unit, and a stop positioning device. The stop positioning device includes an urging unit that urges the moving unit in a direction different from the moving direction before the moving unit reaches the stop position or after reaching the stop position. It is characterized by having.
The moving direction of the moving unit may be unidirectional or bidirectional (reciprocating). When the moving unit stops at the stop position provided on the moving path, the urging unit constituting the stop positioning device moves the moving member before the moving member reaches the stop position or after reaching the stop position. It is biased (pressed) in a direction (reverse direction, other direction, etc.) different from the direction toward the stop position. Thereby, the part tolerance which exists in the drive transmission part which was the cause which gave the movement to the moving direction of a moving part can be eliminated, and it can be set as a state without play. The drive transmission unit may be of any type.
The urging unit may be provided on the moving member (movable member) or on the moving path (fixed member) including the stop position. That is, the elastic urging member may be provided on the inner edge side (or the corresponding base member 41 side) of the moving member so as to operate when the moving member moves toward the closing position. You may provide in the outer edge (or corresponding base member 41 side) of a moving member so that it may operate | move when moving to an open position.

Alternatively, the urging unit may be provided on both the moving member and the fixed member.
The urging unit is, for example, an elastic urging member, and there is no limitation on the configuration and material thereof, and any means such as a compression spring or a tension spring can be used.
In short, the configuration of the elastic urging member and the position where the elastic urging member is arranged are not limited, and the drive mechanism M is configured immediately before (or immediately before) the moving member moves to the stop position or after moving to the stop position. Return the distance corresponding to the play amount of the moving member caused by the dimensional tolerance of the parts group to the limit in the direction opposite to the previous movement direction (other different direction) to the limit, and set the limit state Any means may be used as long as it acts to maintain.

In the second invention, the urging portion is disposed in the moving portion, and a positioning portion is disposed at a position where the urging portion comes into contact with the urging portion when the urging portion moves to the stop position. The portion is configured to bias the moving portion in the different direction by contacting the positioning portion.
When the urging unit is arranged in the moving unit, the locating unit and the urging unit provided at appropriate positions such as the stop position and the moving path come into contact with each other to compress and deform, thereby moving the moving unit in a different direction (reverse direction etc. ) To generate a force to be energized. The location of the positioning unit may be anywhere as long as the moving unit moves toward the stop position and is in contact with the urging unit to generate the urging force.
The third aspect of the present invention is characterized in that the urging portion is disposed at a position in contact with the moving portion that has moved to the stop position.
When the urging unit is not located at the moving part but at the stop position, the movement path, or other part, the urging part is in contact with any part of the moving part to determine the moving part up to that point. Generates forces that bias in different directions.

The fourth aspect of the present invention includes the two moving parts that move between a stop position separated from each other and a close stop position, and the urging part is disposed in at least one of the moving parts. To do.
The approach includes a case where two moving parts are in contact with each other and a state where they are slightly separated. By applying pressure to the urging parts mounted on both moving parts in contact with positioning parts provided at positions where they can contact each urging part, both moving parts are applied in a direction different from the previous moving direction. When the urging force is applied, the urging portion is provided only on one moving portion, and the urging portion provided on one moving portion is brought into contact with the other moving portion when approaching, so that both moving portions are moved in the previous direction. It includes the case of energizing in different directions.
5th invention is equipped with two said moving parts which move between the stop position spaced apart from each other, and the approaching stop position, and each said moving part moves the said urging | biasing part to each said stop position It is arranged at a position in contact with each moving part in the process.
The urging portion is not necessarily arranged on the moving member. Each moving part is arranged by placing an urging part at a position where the moving member is stopped or on a moving path other than the stopping position, or in a position where the moving part comes into contact with the moving part and is brought into contact with each moving part. May be biased in a direction different from the moving direction so far.

The sixth invention is characterized in that the urging portion or the positioning portion can be moved forward and backward from the stop position or the moving path of the moving portion.
When the urging unit and the positioning unit are arranged at positions other than the moving unit, the urging unit and the positioning unit are positioned on the moving path by configuring them so as to be retractable from the moving path of the moving unit. Sometimes a position other than the end of the movement path can be set as the stop position. Further, when the urging unit and the positioning unit are retracted from the stop position on the movement path, the moving unit can be moved beyond the stop position.
In a seventh aspect of the invention, the moving unit is configured to move around in an endless moving path in one direction or in both directions, and the urging force is applied to the moving member, the stop position, or the moving path. It is characterized by arranging the parts.

In an eighth aspect of the present invention, the urging portion disposed on the movement path is configured to be movable forward and backward from the movement path.
The ninth invention is characterized in that the urging force of the urging unit is smaller than the driving force by which the driving unit moves the moving unit.
Since the drive unit moves the moving unit to the stop position against the urging force of the urging unit, the driving force needs to be larger than the urging force of the urging unit.
