The arc-shaped inner rail 61 formed by the above is planted. The inner periphery of the game board 13 is surrounded by the inner rail 61 and the outer rail 62, and the front and rear are surrounded by the game board 13 and the glass unit 16 (see FIG. 1). A game area in which a game is played is formed by the behavior of. The game area is an area formed in front of the game board 13 and defined by the two rails 61 and 62 and a resin outer edge member 73 connecting the rails (a winning opening is provided and fired). Area where the falling sphere flows).

  The two rails 61 and 62 are provided to guide the ball fired from the ball launch unit 112a (see FIG. 4) to the upper part of the game board 13. A return ball preventing member 68 is attached to the front end portion of the inner rail 61 (upper left portion in FIG. 2) to prevent the ball once guided to the upper portion of the game board 13 from returning to the ball guide path again. Is done. A return rubber 69 is attached to the tip of the outer rail 62 (upper right part in FIG. 2) at a position corresponding to the maximum flying portion of the sphere, and the ball launched at a predetermined momentum or more hits the return rubber 69 and gains momentum. Is bounced back to the center while being attenuated.

  First symbol display devices 37A and 37B each having a plurality of LEDs and a 7-segment display as light emitting means are disposed in the lower left portion of the game area when viewed from the front (lower left portion in FIG. 2). The first symbol display devices 37A and 37B display according to each control performed by the main control device 110 (see FIG. 4), and mainly display the gaming state of the pachinko machine 10. In the present embodiment, the first symbol display devices 37 </ b> A and 37 </ b> B are configured to be selectively used depending on whether the ball has won the first prize opening 64 or the second prize opening 640. Specifically, when the ball wins the first winning opening 64, the first symbol display device 37A operates, while when the ball wins the second winning opening 640, the first symbol display device 37A operates. The symbol display device 37B is configured to operate.

  In addition, the first symbol display devices 37A and 37B indicate, by means of LEDs, whether the pachinko machine 10 is in the process of being probable, short-running, or normal, by a lighting state, and whether the pachinko machine 10 is changing or not by a lighting state. , Indicating whether the stop symbol is a symbol corresponding to a probable jackpot, a symbol corresponding to a normal jackpot, or a symbol that is out of place by a lighting state, indicating the number of held balls by a lighting state, and a 7-segment display device, Displays numbers and errors. The plurality of LEDs are configured to have different emission colors (for example, red, green, and blue) of each LED, and the combination of the emission colors may suggest various gaming states of the pachinko machine 10 with a small number of LEDs. it can.

  In the present pachinko machine 10, a lottery is performed in response to winning of the first winning port 64 and the second winning port 640. In the lottery, the pachinko machine 10 determines whether or not it is a big hit (big hit lottery), and also determines the type of the big hit if it is determined to be a big hit. As the jackpot type determined here, 15R probability variation jackpot, 4R probability variation jackpot, and 15R normal jackpot are prepared. The first symbol display devices 37A and 37B not only indicate whether or not the lottery result is a jackpot as a stop symbol after the end of the variation, but if it is a jackpot, a symbol corresponding to the jackpot type is displayed. .

  Here, the “15R probability variation jackpot” is a probability variation jackpot in which the maximum number of rounds shifts to a high probability state after a jackpot of 15 rounds, and “4R probability variation jackpot” is a jackpot with a maximum number of rounds of four. It is a probabilistic jackpot that shifts to a high probability state after. In addition, “15R normal jackpot” is a jackpot that shifts to a low probability state after the maximum number of rounds of 15 rounds and hits a short time during a predetermined number of fluctuations (for example, 100 fluctuations). is there.

  In addition, the “high probability state” means a state in which the jackpot probability thereafter increases as an added value after the jackpot ends, that is, when the probability change is in progress (probability change), in other words, a game that easily shifts to the special game state. It is a state of. The high probability state (during probability change) in the present embodiment includes a game state in which the hit probability of the second symbol, which will be described later, is increased and the ball is likely to win the second winning opening 640. The “low probability state” refers to a time when the probability of jackpot change is not occurring, and a state where the jackpot probability is normal, that is, a state where the jackpot probability is lower than that at the time of probability change. The short time state (short time medium) of the “low probability state” means that the jackpot probability is a normal state, and the jackpot probability remains as it is, and only the hit probability of the second symbol is increased, and the second prize opening 640 is obtained. It means the state of the game where the ball is easy to win. On the other hand, when the pachinko machine 10 is in a normal state is a game state (a state where neither the big hit probability nor the second symbol hit probability is increased) which is neither probabilistic nor short in time.

  During probability change and time reduction, not only does the probability of winning the second symbol increase, but also the time for opening the electric accessory 640a associated with the second prize opening 640 is changed, and the time is longer than normal. Is set. When the electric accessory 640a is in the opened state (open state), the ball wins the second winning opening 640 as compared to the case where the electric accessory 640a is in the closed state (closed state). Easy state. Therefore, during the probability change or the short time, it becomes easy for the ball to win the second winning opening 640, and the number of jackpot lotteries can be increased.

  In addition, during the probability change or during the short time, it is not necessary to change the opening time of the electric accessory 640a associated with the second prize opening 640, or in addition to changing the opening time, It is good also as what changes the frequency | count that the accessory 640a opens more than usual. In addition, the probability of winning the second symbol is not changed during the probability change or in the short time, and the electric accessory 640a is released at the time when the electric accessory 640a associated with the second winning opening 640 is opened and once. It is good also as what changes at least one of the frequency | counts. In addition, during the probability change or in the short time, the time of opening the electric accessory 640a associated with the second winning opening 640 or the number of times of opening the electric accessory 640a per time is not counted, and the second symbol hit Only the probability may be changed so as to increase compared to the normal rate.

  The game area is provided with a plurality of general winning ports 63 through which 5 to 15 balls are paid out as winning balls when the balls win. In addition, a variable display device unit 80 is disposed in the central portion of the game area. The variable display device unit 80 is synchronized with the variable display on the first symbol display devices 37A and 37B by using a winning (start winning) at the first winning port 64 and the second winning port 640 as a trigger. It is composed of a third symbol display device 81 composed of a liquid crystal display (hereinafter simply referred to as “display device”) that performs variable display, and an LED that displays the second symbol in a variable manner with the passage of a sphere of the through gate 67 as a trigger. A second symbol display device (not shown) is provided. The variable display device unit 80 is provided with a center frame 86 so as to surround the outer periphery of the third symbol display device 81.

  The third symbol display device 81 is constituted by a large 9-inch liquid crystal display, and the display content is controlled by the display control device 114 (see FIG. 4). One symbol row is displayed. Each symbol row is composed of a plurality of symbols (third symbol). These third symbols are horizontally scrolled for each symbol column, and the third symbol is variably displayed on the display screen of the third symbol display device 81. It is like that. In the third symbol display device 81 of the present embodiment, the game state is displayed on the first symbol display devices 37A and 37B in accordance with the control of the main control device 110 (see FIG. 4). The decorative display according to the display of the symbol display devices 37A and 37B is performed. Instead of the display device, the third symbol display device 81 may be configured using, for example, a reel.

  Each time the sphere passes through the through gate 67, the second symbol display device alternately turns on the symbol “◯” and the symbol “X” as a display symbol (second symbol (not shown)) for a predetermined time. A variable display is performed. In the pachinko machine 10, when it is detected that the ball has passed through the through gate 67, a winning lottery is performed. As a result of the winning lottery, if the winning symbol is a winning symbol, the symbol “◯” is stopped and displayed on the second symbol display device after the variation of the second symbol is displayed. Further, if the winning lottery results, the symbol of “x” is stopped and displayed on the second symbol display device after the variation of the third symbol is displayed.

  In the pachinko machine 10, when the variable display on the second symbol display device stops at a predetermined symbol (in this embodiment, a symbol “◯”), the electric accessory 640a attached to the second winning opening 640 is displayed for a predetermined time. It is configured to be in an activated state (opened) only.

  The time required for the variable display of the second symbol is set to be shorter during the probability change or during the shorter time than when the game state is normal. As a result, during the probability change and during the time reduction, since the variation display of the second symbol is performed in a short time, the winning lottery can be performed more than during normal. Therefore, since the chance of winning in the winning lottery increases, it is possible to give the player a lot of opportunities for the electric winning component 640a of the second winning opening 640 to be in an open state. Therefore, it is possible to make it easier for the ball to win the second winning opening 640 during the probability change and during the short time.

  It is to be noted that the probability of winning is increased during probability change or time reduction, and other methods such as increasing the opening time and the number of times of opening of the electric accessory 640a per hit are also used to reach the second prize opening 640 during probability change or time reduction. When the ball is in a state where it is easy to win, the time required for the variable display of the second symbol may be constant regardless of the gaming state. On the other hand, when the time required for displaying the variation of the second symbol is set shorter than normal during probability change or short time, the winning probability may be constant regardless of the gaming state, The opening time and the number of opening times of the electric accessory 640a may be constant regardless of the gaming state.

  The through gate 67 is assembled to the game board on the right side in the lower area of the variable display device unit 80, and a part of the ball flowing down to the right side of the game board can pass through the balls launched to the game board. It is configured. When the ball passes through the through gate 67, a winning lottery of the second symbol is performed. After winning the lottery, the 2nd symbol display device displays a variation, and if the winning lottery results, the symbol “○” is displayed as the variable display stop symbol, and the winning lottery result may be off For example, the symbol “x” is displayed as the stop symbol of the variable display.

  The total number of passes through the through-gate 67 of the sphere is held up to a maximum of 4 times, and the number of held balls is displayed by the above-described first symbol display devices 37A and 37B and at the second symbol hold lamp (not shown). Is also displayed. Four second symbol holding lamps are provided for the maximum number of holdings, and are arranged symmetrically below the third symbol display device 81.

  Note that the variable display of the second symbol is performed by switching between lighting and non-lighting of a plurality of lamps in the second symbol display device as in the present embodiment, as well as the first symbol display devices 37A, 37B and the third symbol. A part of the symbol display device 81 may be used. Similarly, the second symbol holding lamp may be turned on by a part of the third symbol display device 81. Further, the maximum number of balls held for passing through the ball of the through gate 67 is not limited to four times, and may be set to three times or less, or five times or more (for example, eight times). Further, the number of through gates 67 to be assembled is not limited to one, and may be plural (for example, two). Further, the assembly position of the through gate 67 is not limited to the right side of the variable display device unit 80, and may be the left side of the variable display device unit 80, for example. In addition, since the number of reserved balls is indicated by the first symbol display devices 37A and 37B, the second symbol hold lamp may not perform lighting display.

  Below the variable display unit 80, a first winning port 64 through which a ball can win is disposed. When a ball wins the first winning port 64, a first winning port switch (not shown) provided on the back side of the game board 13 is turned on, and the main controller 110 is caused by the first winning port switch being turned on. A jackpot lottery is made (see FIG. 4), and a display corresponding to the lottery result is shown on the first symbol display device 37A.

  On the other hand, a second winning port 640 through which a ball can win is disposed on the right side of the first winning port 64 in front view. When a ball wins the second prize opening 640, a second prize opening switch (not shown) provided on the back side of the game board 13 is turned on, and the main controller 110 is caused by the second prize opening switch being turned on. A jackpot lottery is performed (see FIG. 4), and a display corresponding to the lottery result is shown on the first symbol display device 37B.

  Each of the first winning port 64 and the second winning port 640 is also one of winning ports from which five balls are paid out as winning balls when a ball is won. In the present embodiment, the number of prize balls to be paid out when a ball wins the first prize opening 64 and the number of prize balls to be paid out when a ball wins the second prize slot 640 are configured to be the same. The number of prize balls to be paid out when a ball wins the first prize opening 64 is different from the number of prize balls to be paid out when a ball wins to the second prize opening 640, for example, the ball to the first prize opening 64 The number of prize balls to be paid out when a prize is won may be three, and the number of prize balls to be paid out when a ball wins the second prize opening 640 may be five.

  The second winning opening 640 is accompanied by an electric accessory 640a. The electric accessory 640a is configured to be openable and closable. Normally, the electric accessory 640a is in a closed state (reduced state), and it is difficult for the ball to win the second winning opening 640. On the other hand, when the symbol “◯” is displayed on the second symbol display device as a result of the variation display of the second symbol that is triggered by the passage of the ball to the through gate 67, the electric accessory 640a is in an open state (enlarged) State), and the ball is likely to win the second winning opening 640.

  As described above, the probability of hitting the second symbol is higher than that during normal change during the probability change and the short time, and the time required for the variation display of the second symbol is short. "Is easily displayed, and the number of times that the electric accessory 640a is opened (enlarged) is increased. Further, during the probability change and the time reduction, the time for opening the electric accessory 640a also becomes longer than during the normal time. Therefore, it is possible to create a state where the ball is likely to win the second winning opening 640 during the probability change and during the short time compared to the normal time.

  Here, the probability of winning a big hit is the same in both the low probability state and the high probability state when the ball wins the first winning port 64 and when the ball wins the second winning port 640. However, the probability that a 15R probability variation jackpot is selected as the jackpot type selected when the jackpot is won is higher when the ball wins the second winning slot 640 than when the ball wins the first winning slot 64. Is set. On the other hand, the first winning port 64 does not have an electric accessory as in the second winning port 640, and is in a state where the ball can always win.

  Therefore, during normal times, the electric winnings associated with the second winning opening 640 are often in a closed state, and it is difficult to win the second winning opening 640. Then, the ball is fired so that the ball passes to the left of the variable display device unit 80 (so-called “left-handed”), and a lot of opportunities for lottery wins are obtained by winning at the first winning opening 64, resulting in a big hit It is advantageous for the player to aim for this.

  On the other hand, during the probability change or during the short time, passing the ball through the through gate 67 makes it easy for the electric accessory 640a attached to the second winning opening 640 to be in an open state and to easily win the second winning opening 640. Therefore, the ball is fired toward the second prize opening 640 so that the ball passes the right side of the variable display device 80 (so-called “right-handed”), and is passed through the through gate 67 to open the electric accessory. In addition, it is more advantageous for the player to aim for a 15R probability variation jackpot by winning the second winning opening 640.

  As described above, the pachinko machine 10 according to the present embodiment launches a ball to the player in accordance with the gaming state of the pachinko machine 10 (whether it is probable, short, or normal). Can be changed between “left-handed” and “right-handed”. Thus, the player can be changed in the way the ball is hit, so that the game can be enjoyed.

  A first variable winning device 65 is disposed on the upper right side of the first winning port 64, and a specific winning port 65a is provided at a substantially central portion thereof. In the pachinko machine 10, when the jackpot lottery performed due to the winning at the first winning port 64 or the second winning port 640 becomes a jackpot, after a predetermined time (variable time) has passed, The first symbol display device 37A or the first symbol display device 37B is turned on, and a stop symbol corresponding to the jackpot is displayed on the third symbol display device 81 to indicate the occurrence of the jackpot. Thereafter, the gaming state transitions to a special gaming state (big hit) where the ball is easy to win. In this special gaming state, the special winning opening 65a that is normally closed is opened for a predetermined time (for example, until 30 seconds have elapsed or ten balls have been won).

  The specific winning opening 65a is closed when a predetermined time elapses, and after the closing, the specific winning opening 65a is opened again for a predetermined time. The opening / closing operation of the specific winning opening 65a can be repeated up to 15 times (15 rounds), for example. The state in which the opening / closing operation is performed is a form of a special gaming state advantageous to the player, and the player is given out a larger amount of prize balls than usual in order to give a gaming value (game value). Is done.

  Specifically, the first variable winning device 65 includes a front-opening triangular opening / closing plate covering the specific winning opening 65a, and a large opening opening solenoid (not shown) for driving to open / close on the right side about the lower side of the opening / closing plate. )). The special winning opening 65a is normally closed so that the ball cannot win or is difficult to win. In the case of a big win, the large opening opening solenoid is driven to tilt the opening / closing plate to the right side, and an open state in which the ball is likely to win the specific winning opening 65a is temporarily formed. It operates so that these states are repeated alternately.

  Note that the special gaming state is not limited to the above-described form. When the game area is provided with a large opening that is opened and closed separately from the specific winning opening 65a, and the LED corresponding to the jackpot is turned on in the first symbol display devices 37A and 37B, the specific winning opening 65a is opened for a predetermined time, A special game in which a large opening provided separately from the specific winning port 65a is opened for a predetermined time and a predetermined number of times when the ball wins into the specific winning port 65a while the specific winning port 65a is opened. You may make it form as a state. Further, the number of the specific winning opening 65a is not limited to one, and one or more than two (for example, three) may be arranged, and the arrangement position is the lower right side of the first winning opening 64 or the first For example, the left side of the variable display unit 80 is not limited to the lower left side of the winning opening 64.

The slide hole 412 is connected to the approximate center of each base member 410 and has a pair of intermediate slide holes 412a whose extending directions coincide with each other. An outer slide hole 412b formed on the outside of the slide hole 412a (opposite side to which the pair of base members 410 oppose) and an inner side of the intermediate slide hole 412a (opposite side of the pair of base members 410) An inner slide hole 412c. The outer slide hole 412b and the inner slide hole 412c are formed in a staggered manner. That is, for example, when the outer slide hole 412 b is formed in the upper part of the base member 410, the inner slide hole 412 c is formed in the lower part of the base member 410.

  The fixed rack gear member 414 is fastened to the base member 410 while being in contact with the alignment wall 413 for the purpose of transmitting a driving force to the first gear group 440 and the second gear group 450, and has a bar shape with a rectangular cross section. Permanent rack gear 414a engraved over an outer surface that is a member to be formed, which is a side surface that is in contact with alignment wall 413, and a surface opposite to the outer surface that is formed in parallel with the outer surface. And a limited rack gear 414b which is engraved adjacent to the front side (front side in FIG. 10) of the permanent rack gear 414a and which is engraved only near the center of the base member 410.

  The permanent rack gear 414a meshes with the second gear group 450, and the limited rack gear 414b meshes with the first gear group 440, details of which will be described later. Further, the limited rack gear 414b has a start gear tooth 414b1 (end gear tooth) arranged on the side where the first gear group 440 starts to mesh with the deformed gear 441, and is formed larger than the other gear teeth. (See FIG. 10).

  The slide member 420 is a member that is slid up and down while the meniscus member 460 is disposed at the center. The slide members 420 are formed in a pair of upper and lower parts, and since the configuration of each slide member 420 is common (point symmetry at the center point in front view), only one (upper side) slide member 420 will be described, and the other (lower side). Description of the slide member 420 is omitted.

  That is, one slide member 420 is formed in a rectangular plate shape that is elongated in the left-right direction and has a main body portion 421 in which steps are formed on the front side at both ends, and vertically downward from both ends of the main body portion 421. A pair of transmitted leg portions 422 that extend, a pair of side wall portions 423 that extend in a plate shape from the upper and lower ends of the main body portion 421 to the back side (front side in FIG. 11), and a protrusion from the back surface of the main body portion 421 A plurality of first pivot pins 424 that are provided in the left-right direction and a plurality of second pivot pins 425 that project from the back of one end of the main body 421 (to the right in FIG. 11). And mainly.

  The main body portion 421 is disposed so as to face the large-diameter shaft support hole 421a formed in the central portion, the rotation restricting hole 421b formed in an arc shape coaxial with the shaft support hole 421a, and the upper side wall portion 423. And a slide regulating wall portion 421c whose central side is close to the side wall portion 423 and a slide regulating pin 421d that protrudes to the back side at both ends and is formed in a pair of upper and lower sides. The

  The shaft support hole 421a is an opening through which the arcuate wall portion 461c of the meniscus member 460 is inserted, and the shaft support hole 421a has a diameter slightly larger than the outer diameter of the arcuate wall portion 461c. The meniscus member 460 and the reverse gear 453 are connected through the shaft support hole 421a so as not to rotate relative to each other.

  The rotation restricting hole 421b is an opening through which the locking pin 461e of the meniscal member 460 is inserted, and the width of the rotation restricting hole 421b is slightly larger than the diameter of the locking pin 461e. When the locking pin 461e is brought into contact with the end of the rotation restricting hole 421b, further rotation of the meniscus member 460 is restricted.

  The slide regulating wall portion 421c is a portion that accommodates the slide rack 442 of the first gear group 440 between the upper side wall portion 423 of the main body portion 421, and a portion formed in a step has a biasing force on the slide rack 442. The urging spring 442c is applied in such a manner as to stop one end thereof.

  The slide restricting pin 421d is a cylindrical member that is inserted into the ring-shaped collar member C and inserted into the intermediate slide hole 412a of the base member 410, and the retaining plate B is fastened and fixed at the tip.

  The collar member C (see FIG. 17A) is formed in a ring shape having a flange (large diameter portion). The outer diameter of the flange is formed to be larger than the width of each slide hole 412a to 412c including the intermediate slide hole 412a, and the outer diameter of the ring portion where the flange is formed is each slide hole 412a to 412c including the intermediate slide hole 412a. It is formed slightly smaller than the width. Therefore, the flange is interposed between the main body portion 421 of the slide member 420 and the main body portion 411 of the base member 410, and the ring portion of the collar member C is accommodated in the intermediate slide hole 412a with a slight gap. Thereby, the slide restricting pin 421d is formed to be freely movable in the extending direction of the intermediate slide hole 412a, while the movement in the direction orthogonal to the extending direction of the intermediate slide hole 412a is restricted.

  The retaining plate B (see FIG. 19A) is formed with a width larger than the width of each of the slide holes 412a to 412c including the intermediate slide hole 412a. Therefore, in a state where the retaining plate B is fastened to the slide restriction pin 421d, the slide member 420 is connected to the base member 410 so as not to be pulled out.

  In addition, the retaining plate B has a fastening hole formed on the surface that contacts the end of the slide restricting pin 421d, and the periphery of the fastening hole is built up in the same shape as the ring portion of the collar member C. The built-up portion is accommodated in the intermediate slide hole 412a. As a result, the collar member C is disposed at the root portion of the slide restricting pin 421d and the built-up portion of the retaining plate B is disposed at the tip portion, so that the shaft of the slide restricting pin 421d can be used as the intermediate slide hole. The slide holes 412a to 412c including the 412a can be stably supported while being matched with the opening direction (see FIG. 19A).

  The transmitted leg portion 422 is a portion to which the driving force of the driving device 470 is transmitted, and is the same as the rack gear 422a meshed with the driving gear 473 of the driving device 470 and the slide restriction pin 421d of the main body portion 421. A protruding slide regulating pin 422b, a front side wall portion 422c that covers the side surface of the front side of the rack gear 422a (a direction perpendicular to the gear teeth continuous direction), and a front side wall portion 422c are formed. And a cutout portion 422d which is an arcuate cutout.

  Similar to the slide restriction pin 421d, the slide restriction pin 422b is provided with the collar member C and the retaining plate B, and is inserted into the slide holes 412b and 412c of the base member 410. In this embodiment, the slide restricting pin 422b of the transmitted leg portion 422 on the right side when viewed from the front is inserted into the outer slide hole 412c of the base member 410, and the slide restricting pin of the transmitted leg portion 422 on the left side when viewed from the front. 422b is inserted through the inner slide hole 412c of the base member 410. Thus, in a state where the retaining plate B is fastened to the slide restricting pin 422b, the slide restricting pin 422b is stably supported while being aligned with the opening direction of the slide holes 412b and 412c, and the slide member 420 and the base The member 410 can be connected so that it cannot be pulled out.

  The front side wall portion 422c is formed in a manner capable of overlapping with the gear teeth of the drive gear 473 in a front view in the assembled state (see FIG. 18).

  The notch 422d has a representative circle slightly larger than the tooth tip circle of the drive gear 473 when the pair of slide members 420 are disposed at the retracted position (see FIG. 9A). When the two are arranged together, the representative circle is formed in a portion projected onto the front side wall portion 422c in front view.

  The side wall part 423 includes a notch part 423a that is notched above and below a region where the shaft support hole 421a of the main body part 421 is formed. The notch 423a serves as a portion through which the drive lever 467 of the meniscus member 460 passes.

  The first shaft support pin 424 includes a raised shaft support pin 424a in which a plurality (three in this embodiment) are continuously provided from the back surface of the slide member 420, and a double-layer gear adjacent to the shaft support hole 421a of the slide member 420. The shaft support pin 424b is mainly provided.

  Since the raised shaft support pin 424a includes a ring-shaped portion having the same height around the periphery, the inserted second gear group 450 is raised from the main body portion 421 of the slide member 420 (with a predetermined distance from the main body portion 421). It is pivotally supported. Thereby, the 1st gear group 440 can be arrange | positioned in the space.

  The back cover 430 is a member that covers the body portion 421 and the pair of side wall portions 423 of the slide member 420 by being fastened and fixed to the back surface of the slide member 420, and a pair of insertions through which the slide restriction pins 421d are inserted. A hole 430a is formed in each one end.

  The first gear group 440 is a gear group that is housed between the slide member 420 and the back cover 430 and meshed with the limited rack gear 414b, and has a deformed gear 441 meshed with the limited rack gear 414b and a side surface. The rack gear 442b is engraved and the slide rack 442 is slid along the slide restricting wall portion 421c of the slide member 420, the pair of transmission gears 443 for transmitting the rotation of the deformed gear 441 to the slide rack 442, and the deformed gear. An intermediate plate 444 that is a plate-like member that covers the transmission gear 443 disposed on the deformed gear 441 side from the axial direction, and is fastened and fixed to the main body 421 of the slide member 420. Is mainly provided.

  The deformed gear 441 includes a starting gear tooth 441a which is formed larger than other teeth among the gear teeth to be engraved.

  The deformed gear 441 and the pair of transmission gears 443 are each supported by a plurality of second shaft support pins 425 of the slide member 420.

  The slide rack 442 includes a main body portion 442a formed in a rectangular bar shape, a rack gear 442b formed on one side surface of the main body portion 442a and meshed with the transmission gear 443, and protrudes from the side surface of the main body portion 442a. And an urging spring 442c locked to the protruding portion.

  The urging spring 442c is engaged with the step portion of the slide restricting wall portion 421c of the slide member 420, thereby generating an urging force that pushes the slide rack 442 back to the transmission gear 443 side.

  The intermediate plate 444 is a plate that divides the first gear group 440 and the second gear group 450 into front and rear, and a shaft support pin 444a projects from the front side.

  Of the plurality of gears of the second gear group 450, a transmission gear 451 that is meshed with the permanent rack gear 414a of the base member 410 is pivotally supported by the shaft support pin 444a.

  The second gear group 450 has a role of reversing the meniscus member 460 by rotating the reversing gear 453 using the vertical displacement of the slide member 420, and a plurality of (four in the present embodiment) are arranged in the left-right direction. ) And a plurality of transmission gears 451 whose outer end gear meshes with the permanent rack gear 414a of the base member 410, and an inner end portion of the plurality of transmission gears 451 opposite to the permanent rack gear 414a. A two-layer gear 452 in which gear teeth 452a on the upper layer (rear layer) are meshed with a transmission gear 451 pivotally supported on the shaft, and a split gear tooth 452b on a lower layer (front layer) of the two-layer gear 452 And a reversing gear 453 to be meshed.

  In the transmission gear 451, among the plurality of gears, the gear at the end of the base member 410 on the permanent rack gear 414 a side is pivotally supported by the pivot pin 444 a of the first gear group 440, and the other gears are supported by the raising shaft of the slide member 420. It is pivotally supported by the pin 424a.

  As described above, since the raised shaft support pin 424a includes a ring-shaped portion having the same height around the transmission pin 424a, the transmission gear 451 is raised from the main body portion 421 of the slide member 420 (with a predetermined distance from the main body portion 421). It is pivotally supported. Thereby, the axial direction height of the transmission gear 451 pivotally supported by the pivot pin 444a of the first gear group 440 and the other transmission gear 451 can be matched. That is, the plurality of transmission gears 451 are axially supported with a predetermined distance from the main body 421 of the slide member 420.

  The two-layer gear 452 is formed of a resin material, and gear teeth 452a engraved in the upper layer (back side layer), divided gear teeth 452b engraved in the lower layer (front side layer), upper layer and lower layer And a sliding wall portion 452d that is an arcuate wall surface that is slid by the arcuate recess 453c of the reversing gear 453 (see FIG. 20).

  Since the gear teeth 452a are always meshed with the transmission gear 451, the two-layer gear 452 is always rotated when the slide member 420 slides up and down.

  The lower layer of the two-layer gear 452 is composed of a region in which the dividing gear teeth 452b are engraved and a region in which the sliding wall portion 452d is formed, and another intermediate portion at the boundary between the dividing gear teeth 452b and the sliding wall portion 452d. Starting gear teeth 452b1 larger than the gear teeth 452b2 are engraved. Note that the depressions 452b3 and 452b4 (see FIG. 20) formed on both sides of the starting gear tooth 452b1 as receiving portions of the gear teeth are formed deeper than the depressions between the gear teeth of the intermediate gear teeth 452b2. As a result, the starting gear teeth 453b1 formed larger than the intermediate gear teeth 453b2 of the reversing gear 453, which will be described later, can be received with good meshing (a state where the gear teeth are meshed deeply). Therefore, even when the size of the gear teeth varies from one tooth to another, the meshing relationship between the two-layer gear 452 and the reverse gear 453 can be kept good.

  The depressions 452b3 and 452b4 formed on both sides of the starter gear teeth 452b1 function as receiving parts for the starter gear teeth 453b1 of the reversing gear 453 (see FIG. 23B). Of the recesses 452b3 and 452b4, the side close to the sliding wall 452d is referred to as a first recess 452b3, and the opposite side of the first recess 452b3 is referred to as a second recess 452b4.

  The gear teeth 452b are formed smaller than the starting gear teeth 452b1 of the divided gear teeth 452b and larger than the intermediate gear teeth 452b2. As a result, as will be described later, the misalignment at the start of meshing between the start gear teeth 452b1 of the double-layer gear 452 and the start gear teeth 453b1 of the reversing gear 453 is suppressed, and the rotation accuracy when the meshing continues is improved. Can be made.

  Note that the start of meshing means the time when the starting gear teeth 452b1 of the double-layer gear 452 and the reversing gear 453 start to contact, and is not limited to when the gear teeth start to contact each other. In the present embodiment, it means a time when the starting gear teeth 452b1 of the double-layer gear 452 and the engaging protrusion receiving portion 453d of the reversing gear 453 are brought into contact with each other.

  Further, when the meshing continues, the intermediate gear teeth 452b2 and 453b2 are meshed after the starter gear teeth 452b1 and 453b1 mesh.

  As a method of increasing the size of the starting gear tooth 452b1, a method of increasing the tooth width (the length along the axial direction of the gear) is also conceivable. However, in this embodiment, because the two-layer gear 452 can be easily formed into a two-layer structure, the start gear teeth 452b1 and the intermediate gear teeth 452b2 are formed to have the same tooth width and the tooth thickness (the dimension in the tooth continuous direction). ) And toothpaste are increased.

  The disc portion 452c is formed so as to overlap with the gear teeth of the transmission gear 451 adjacent to the two-layer gear 452 and the gear teeth of the reversing gear 453 adjacent to the two-layer gear 452 in the axial direction (FIG. 21B). reference). As a result, when the transmission gear 451 and the reverse gear 453 move in the axial direction, the gear teeth are brought into contact with the disk portion 452c, thereby preventing the transmission gear 451 and the reverse gear 453 from wobbling. And further movement of the transmission gear 451 and the reverse gear 453 can be suppressed.

  The reversing gear 453 is a member that reverses the meniscus member 460 by being meshed with and rotated by the two-layer gear 452, and a main body portion 453 a formed into a tubular shape through which the cylindrical main body 462 a of the meniscal member 460 can be inserted. A reversing gear tooth 453b formed outwardly from one end of the main body 453a, and a main body 453a formed adjacent to the reversing gear tooth 453b in the direction along the outer periphery of the cylindrical main body 462a. An arc-shaped concave portion 453c that is an arc-shaped wall surface that is disposed on the shaft object and is slid by the sliding wall portion 452d of the two-layer gear 452, and a wide protrusion that forms the arc-shaped concave portion 453c. It mainly includes an engaging protrusion receiving portion 453d and a locking protrusion 453e that protrudes in the radial direction from a position obtained by dividing the outer peripheral surface of the main body 453a into three equal parts.

  The reversing gear teeth 453b are engraved at both ends thereof with starting gear teeth 453b1 larger in size (tooth thickness and tooth injury) than the intermediate gear teeth 453b2 (the gear teeth other than both ends). The recess 453b3 formed between the starting gear tooth 453b1 and the engaging protrusion receiving portion 453d as a gear tooth receiving portion is deeper than the recess formed between the gear teeth of the intermediate gear tooth 453b2. It is formed. Thereby, the starting gear teeth 452b1 formed larger than the intermediate gear teeth 452b2 of the two-layer gear 452 can be received with good meshing (a state where the gear teeth mesh deeply). Therefore, even when the size of the gear teeth varies from one tooth to another, the meshing relationship between the two-layer gear 452 and the reverse gear 453 can be kept good.

  The arc-shaped concave portion 453c is a portion that comes into contact with the sliding wall portion 452d of the two-layer gear 452, and is formed with a radius of curvature substantially the same as the radius of the sliding wall portion 452d.

  The locking projection 453e is fitted in an arc-shaped wall portion 461c formed in the main body portion 461 of the meniscal member 460 in a manner in which relative locking is impossible. Thereby, the reversing gear 453 and the meniscal member 460 are rotated together.

  Next, the meniscal member 460 will be described with reference to FIGS. 14 and 15. FIG. 14 is a front perspective view of the meniscal member 460, and FIG. 15 is a rear perspective view of the meniscal member 460. 14 and 15 show a state where the front cover 466 is removed from the main body 461 of the meniscal member 460.

And a locking pin 461e that protrudes.

  The locking pin 461e is inserted into the rotation restricting hole 421b of the slide member 420 in the assembled state (see FIG. 21A). Thereby, the rotation angle of the meniscus member 460 is regulated.

  The center gear 462 includes a cylindrical main body 462a that is inserted into the connection hole 461a of the main body 461, a flange 462b that is formed in a radial flange shape from one end of the cylindrical main body 462a, and a flange thereof. A drive lever 467 is formed to be fastened and fixed to the gear tooth 462c engraved inward in the radial direction from the outer peripheral surface of 462b and the other end that is opposite to one end of the cylindrical main body 462a. The fastening hole 462d is mainly provided with a claw-like flange portion 462e with one end hooked to the other end of the urging spring locked to the flange portion 461d of the main body portion 461.

  The slide plate portion 463b is inserted into a long hole-like slide hole 466a formed in the front cover 466. Accordingly, the claw member 463 is formed to be slidable in the extending direction of the slide hole 466a of the front cover 466.

  The crank gear 464 is supported by a shaft support pin 461b of the main body portion 461, and a main body portion 464a whose gear teeth are engraved on the outer peripheral surface, and a slide projecting eccentrically with the rotation shaft of the main body portion 464a. A pin 464b.

  The main body 464 a is rotated with the rotation of the central gear 462 by being engaged with the central gear 462 and the transmission gear group 465.

  The slide pins 464b are moved about the respective pivot pins 461b as the main body 464a is rotated. As a result, the slide pin 464b is moved between a first position (see FIG. 14) arranged close to the center gear 462 and a second position arranged away from the center gear 462. By the movement of the slide pin 464b, the claw member 463 is moved along the slide hole 466a of the front cover 466 (see FIG. 26B).

  The lever portion 467a (see FIG. 13) is a portion that is pushed by the slide rack 442. When the lever portion 467a is pushed by the slide rack 442, the center gear 462 is rotated.

  Returning to FIG. 10 from FIG. The driving device 470 is disposed so as to be raised to the front side at the center portion of the base member 410 and fastened and fixed to the base member 410, and a drive motor 472 fastened and fixed to the fastening plate portion 471. And a drive gear 473 inserted through the drive shaft of the drive motor 472.

  The fastening plate portion 471 includes a pair of restriction wall portions 471a and 471b that are formed in a circular arc shape along the outer shape of the motor case of the drive gear 472 and extend to the front side, and one restriction wall portion 471a ( The inner side in the assembled state is extended to a substantially intermediate position of the motor case, and the other regulating wall portion 471b (outer side in the assembled state) is extended longer than the extending end of the one regulating wall portion 471a. The pair of restriction wall portions 471a and 471b are used as a guide when the drive motor 472 is pulled out from the fastening plate portion 471.

  The drive gear 473 is arranged to face the rack gear 422a of the pair of slide members 420 from both sides, and meshes from both sides.

  Next, an overview of the movement of the pair of slide members 420 of the combined operation unit 400 will be described with reference to FIGS. 16 and 18 are partial front views of the combined operation unit 400, FIG. 17A is a partial cross-sectional view of the combined operation unit 400 taken along the line XVIIa-XVIIa in FIG. 16, and FIG. 17A is a partial cross-sectional view of the composite operation unit 400 after the drive device 470 is moved from FIG. 17A, and FIG. 19A is a partial cross-sectional view of the composite operation unit 400 taken along the line XIXa-XIXa in FIG. FIG. 19B is a partial cross-sectional view of the combined operation unit 400 after the drive motor 472 is separated from the drive gear 473 from FIG. 19A. 16 and 17 illustrate a state where the pair of slide members 420 are disposed at the retracted position, and FIGS. 18 and 19 illustrate a state where the pair of slide members 420 are disposed at the extended position.

  As shown in FIGS. 16 and 18, the pair of slide members 420 sandwich the drive gear 473 of the drive device 470 between the transmitted leg portions 422. At this time, the rack gear 422a of the transmitted leg portion 422 that is opposed to the drive gear 473 is engaged with the single drive gear 473. As a result, the drive gear 473 is rotated by the drive motor 472, so that the transmitted leg portions 422 opposed to each other across the drive gear 473 are slid and moved in synchronization.

  That is, in the state where the slide member 420 is disposed at the retracted position (see FIG. 16), the drive gear 473 is rotated clockwise in front view, so that the upper slide member 420 is moved downward and the lower slide member 420 is moved downward. Are moved upward at a constant speed. At this time, the pair of drive motors 472 arranged on the left and right are controlled synchronously, and the pair of slide members can be stably slid.

  Further, the weights of the pair of slide members 420 are applied in directions opposite to the drive gear 473. For example, the right driving gear 473 is weighted in the direction of rotating the driving gear 473 clockwise from the upper slide member 420, and the driving gear 473 is counterclockwise rotated from the lower slide member 420. The weight is applied in the direction of rotation. Thus, if the weights of the pair of slide members 420 are equal to each other, the drive gear 473 can be kept stopped by the balance of the weights of the pair of slide members 420 even when the power of the drive motor 472 is cut off. Therefore, even if the power of the drive motor 472 is cut off when the pair of slide members 420 are arranged at arbitrary positions, the pair of slide members 420 can be kept stopped at that position.

  The pair of transmitted leg portions 422 of the slide member 420 are engaged with the drive gear 473 from the same direction. That is, for example, the pair of left and right transmitted leg portions 422 of the upper slide member 420 are engaged with the drive gear 473 from the right side when viewed from the front, and the pair of left and right transmitted leg portions 422 of the lower slide member 420 are left and right. Both are engaged with the drive gear 473 from the left side when viewed from the front.

  As a result, even if one of the transmitted leg portions 422 meshed with the drive gear 473 suddenly moves (for example, when the distance from the meshed drive gear 473 increases) The other transmitted leg 422 connected to one transmitted leg 422 via the main body 421 is moved in the same direction as the one transmitted leg 422. That is, since it moves in the direction away from the drive gear 473 engaged, it can suppress applying a big load to the drive gear 473 engaged with the other to-be-transmitted leg part 422.

  Here, for example, one transmitted leg portion 422 of the slide member 420 is engaged with the drive gear 473 from the right side when viewed from the front, and the other transmitted leg portion 422 is engaged with the drive gear 473 from the left side when viewed from the front. Then, one of the transmitted leg portions 422 is moved from the drive gear 473 in a direction in which the distance increases, so that the other transmitted leg portion 422 is pressed against the drive gear 473. As a result, a large load is applied to the drive gear 473 engaged with the other transmitted leg portion 422.

  On the other hand, in the present embodiment, as described above, it is possible to prevent a large load from being applied to the drive gear 473. Therefore, the proper meshing relationship between the drive gear 473 and the rack gear 422a of the transmitted leg 422 is appropriate. Can be achieved. Moreover, the shape of a pair of slide member 420 can be made equivalent, and a member can be made shared.

  As shown in FIG. 19A, the drive gear 473 and the front side wall portion 422c interfere in the front-rear direction (FIG. 19A, the vertical direction on the paper surface). On the other hand, in a state where the pair of slide members 420 are disposed at the retracted position (see FIG. 16), the drive gear 473 can be visually recognized in a state of being spaced from the outer shape of the notch 422d in front view. The positional relationship between the slide member 420 and the drive gear 473 will be described as a specific phase position. “The drive gear 473 can be visually recognized in a state of being spaced from the outer shape of the notch 422d in front view”.

  Therefore, in a state where the pair of slide members 420 are disposed at the retracted position (specific phase position) that is the end of the movable range, the drive gear 473 can be pulled out through the notch portion 422d formed in the transmitted leg portion 422. . Thereby, the drive gear 473 can be replaced without removing the slide member 420 from the base member 410 (see FIG. 17B). Therefore, maintainability of the drive gear 473 can be improved.

  Here, the pair of slide members 420 are disposed opposite to each other with the drive gear 473 interposed therebetween, and meshed with the drive gear 473 by the rack gear 422a of each transmitted leg portion 422. In this state, it is necessary to form a state in which the pair of slide members 420 are similarly disposed at the retracted position (see FIG. 16). Therefore, the drive gear 473 and the rack gear 422a are engaged with each other with arbitrary gear teeth. It ’s not good. That is, the drive gear 473 and the rack gear 422a of the pair of slide members 420 are fixed so that the gear teeth meshing with each other are fixed (representative gear teeth of the rack gear 422a that are brought into contact with the representative gear teeth of the drive gear 473 when engaged. Is formed).

  In order to form the proper meshing state, the notch 422d of the slide member 420 can be used. That is, the cutout portion 422d has a representative circle slightly larger than the addendum circle of the drive gear 473 when the pair of slide members 420 are disposed at the retracted position (see FIG. 16) as described above. When the shaft and the center axis are arranged together, it is formed in a portion projected onto the front side wall portion 422c in the front-rear direction (the vertical direction in FIG. 16).

  Therefore, the notch portion 422d is disposed to face the pair of slide members 420 in a state where the pair of slide members 420 are disposed at the retracted position (see FIG. 16). In this state, the drive gear 473 is moved through the notch 422d (moved in the direction perpendicular to the plane of FIG. 16), so that the drive gear 473 and the rack gear 422a can be meshed with each other in an appropriate meshing state.

  In a state in which the pair of slide members 420 are arranged at the retracted position (specific phase position), the pair of slide members 420 is blocked from moving outward in the vertical direction (the upper slide member 420 is the upper slide member and the lower slide member is the upper slide member 420). 420 is blocked from further movement downward). That is, when the slide member 420 is randomly moved to the retracted position side, the slide member 420 is stopped at least at the retracted position (moving resistance increases).

  Therefore, in adjusting the position of the slide member 420 when the maintenance worker replaces the drive gear 473, even if the slide member 420 is randomly moved in the retract direction, the slide member 420 is the retracted position (specific phase) that is the end of the movable range. Position). Accordingly, the drive gear 473 can be easily taken out through the notch 422d, and the drive gear 473 can be easily meshed with the rack gear 422a of the pair of slide members 420 in this state. Therefore, maintainability can be improved.

  The arrangement of the driving device 470 will be described with reference to FIG. As described above, since the notch portions 422d are formed in the pair of slide members 420, the assembled driving device 470 is fastened and fixed to the base member 410 in a state where the pair of slide members 420 are disposed at the retracted position. be able to. Thereby, the arrangement | positioning freedom degree of the drive device 470 can be improved.

  That is, when the notch portion 422d is not formed in the front side wall portion 422c of the slide member 420 (for example, when the front side wall portion 422c is formed in the entire region of the rack gear 422a), the driving device 470 is attached to the base member 410. Even if it tries to assemble | attach, the drive gear 473 will contact | abut to the front side wall part 422c, and the drive device 470 cannot be assembled | attached to the base member 410. FIG. Therefore, the driving device 470 has to be disposed on the opposite side of the front side wall portion 422c, and the degree of freedom in arranging the driving device 470 is low.

  On the other hand, in the present embodiment, the notch 422d is formed in the front side wall 422c, so that the drive gear 473 is moved in the front-rear direction through the notch 422d, so that the drive device 470 is moved to the slide member 420. It can be disposed on the front side (the side on which the front side wall portion 422c is disposed). Therefore, the degree of freedom of arrangement of the driving device 470 can be improved.

  Further, a front side wall portion 422c of the slide member 420 is formed in a layer between the drive gear 473 and the drive motor 472, and the drive gear 473 and the front side wall portion 422c are moved back and forth by moving the slide member 420 from the retracted position. They can be overlapped in a direction view (viewed in the vertical direction in FIG. 16). Accordingly, when the drive device 470 is replaced, it is possible to select whether to remove the drive motor 472 and the drive gear 473 together or to remove only the drive motor 472 while leaving the drive gear 473.

  That is, the drive motor 472 and the drive gear 473 can be separated by pulling out the drive motor 472 while keeping the drive gear 473 in contact with the front side wall portion 422c of the slide member 420 (see FIG. 19B). . As a result, the drive motor 472 can be replaced while maintaining the meshing state between the drive gear 473 and the rack gear 422a of the transmitted leg 422. Therefore, before and after replacement of the drive motor 472, it is not necessary to adjust the meshing between the drive gear 473 and the rack gear 422a of the transmitted leg portion 422 again, and the maintainability can be improved.

  At this time, the drive gear 473 overlaps with the front side wall portion 422c of the pair of transmitted leg portions 422 arranged to face each other with the drive gear 473 interposed therebetween (see FIG. 18). Therefore, when the drive gear 473 is pulled out from the drive motor 472, a force is applied to the drive gear 473 from at least two points arranged opposite to each other with the rotation shaft interposed therebetween. Therefore, the drive motor 472 is restrained from tilting with respect to the drive gear 473.

  Further, when the drive motor 472 is pulled out from the fastening plate portion 471, the drive motor 472 can be moved along the restriction wall portions 471a and 471b while being pressed against the restriction wall portions 471a and 471b. Inclination of the shaft center with respect to the drive gear 473 can be suppressed. Thereby, it can suppress that the drive gear 473 deform | transforms.

  As shown in FIG. 19A, one regulating wall portion 471 a is formed so as to retract from the front end surface of the motor case of the drive motor 472 toward the fastening plate portion 471. As a result, the drive motor 472 can be pulled out with the extended end of one of the restriction walls 471a as the fulcrum S. That is, since the extending end of the one regulating wall portion 471a and the side surface of the drive motor 472 are disposed adjacent to each other, the extending end of the one regulating wall portion 471a is used as a fulcrum S and the side surface of the driving motor 472 (FIG. 19). In (a), for the sake of easy understanding, the distance between the fulcrum S and the action point W when the force is applied to the drive motor 472 with the action point W being shown as an action point W in the drive motor 472 is minimized. It can be. As a result, the force required to pull out the drive motor 472 can be suppressed depending on the setting of the power point. FIG. 19A shows the relationship between the fulcrum S and the action point W and a virtual insulator.

  In addition, the drive motor 472 can be pulled out while pressing the drive motor 472 against the other restriction wall 471b disposed to face the one restriction wall 471a. Accordingly, it is possible to suppress the degree of inclination of the drive motor 472 with respect to the drive gear 473 when the drive motor 472 is pulled out.

  As shown in FIG. 19A, the other restriction wall 471b is formed to project forward (upward in FIG. 19A) from the extending end of the one restriction wall 471a. As a result, when the drive motor 472 is pulled out with the one restriction wall 471a as the fulcrum S, the drive motor 472 is moved from the other restriction wall 471b in the state W1 where the action point W is closest to the other restriction wall 471b. For this reason, it is possible to apply a force toward the direction of pushing back to the action point W. Therefore, the other restriction wall 471b can prevent the drive motor 472 from moving in the direction perpendicular to the drive shaft. Accordingly, when the drive motor 472 is pulled out, the drive motor 472 can be reliably prevented from moving in a direction away from the one regulating wall portion 471a.

  Next, the two-layer gear 452 related to the rotation of the meniscal member 460 of the combined operation unit 400 will be described with reference to FIG. 20A is a front view of the two-layer gear 452, and FIG. 20B is a rear view of the two-layer gear 452.

  As shown in FIGS. 20A and 20B, the two-layer gear 452 is a gear member in which different gear teeth are engraved on the front side and the back side with the disc portion 452c as a boundary. As shown in FIG. 20A, the starting gear teeth 452b1 adjacent to the sliding wall portion 452d are formed larger than the intermediate gear teeth 452b2. Therefore, as will be described later, the starter gear teeth 452b1 can be provided with durability that can withstand a collision (contact) with the reversing gear 453. In the present embodiment, only the starting gear teeth 452b1 adjacent to the sliding wall 452d are formed in a large size, and the intermediate gear teeth 452b2 are formed in a small size, so that the durability is improved and the material cost is suppressed. Both can be achieved.

  The double-layer gear 452 includes a hollow bottom wall 452e as a wall surface that forms the bottom of the first hollow 452b3 and the second hollow 452b4, and a push-back rib 452f that connects the hollow bottom wall 452e and the ring-shaped rib. .

  Here, the second depression 452b4 needs to have a sufficient depth as a depression for receiving the starting gear teeth 453b1 of the reversing gear 453 (see FIG. 23), while the first depression 452b3 is engaged with the reversing gear 453. This is a recess into which the protruding receiving portion 453d enters. For this reason, the depth of the second depression 452b4 is not required, but in the present embodiment, the first depression 452b3 and the second depression 452b4 are formed with substantially the same depth. As a result, the amount of heat shrinkage of the resin material in the vicinity of the first dent 452b3 and the second dent 452b4 when the two-layer gear 452 is molded can be made uniform, and the moldability of the two-layer gear 452 can be improved. it can.

  As shown in FIG. 20A, a space is formed in a region surrounded by the wall portion formed by the bottom of the sliding wall 452d and the intermediate gear teeth 452b2 and the hollow bottom wall 452e. At this time, the sliding wall 452d and the hollow bottom wall 452e are formed with substantially the same thickness, so that the occurrence of sink marks peculiar to resin molding can be suppressed. Moreover, the material cost of the resin material can be suppressed.

  Here, the hollow bottom wall 452e is not necessarily required to ensure the function of the two-layer gear 452. On the other hand, the starting gear teeth 452b1 and the sliding wall portion 452d are formed in such a manner that they are connected by the hollow bottom wall portion 452e. Therefore, it is possible to disperse the impact when the starting gear teeth 452b1 abut on the reversing gear 453 (see FIG. 23B).

  The push-back rib 452f is connected to the recess bottom wall 452e of the second recess 452b4. Here, the direction of the line of force F (see FIG. 23B) generated when the reversing gear 453 is brought into contact with the starter gear teeth 452b1 is directed toward the pushback rib 452f. Accordingly, even when a space is formed in the region surrounded by the wall portion formed by the sliding wall portion 452d of the double-layer gear 452 and the bottom portion of the intermediate gear teeth 452b2, and the hollow bottom wall portion 452e, the push-back rib 452f is formed. As a result, the resistance to the force F can be improved. Therefore, it is possible to prevent the start gear teeth 452b1 from being deformed by an impact at the time of contact.

  As shown in FIG. 20B, the gear teeth 452a are formed around the periphery of the double-layer gear 452. Since the gear teeth 452a are always meshed with the transmission gear 451 (see FIG. 21B), the two-layer gear 452 is always rotated when the slide member 420 slides up and down (see FIG. 21A). .

  Next, with reference to FIGS. 21 to 26, the details of the movement of the combined operation unit 400, that is, the operations of the slide member 420 and the meniscal member 460 that are moved by transmitting the driving force of the driving device 470 will be described. To do. FIG. 21 to FIG. 26 illustrate the operation of the composite operation unit 400 in time series. 21 to 26, the back cover 430 is not shown for easy understanding.

  21A and 22A are rear views of the composite operation unit 400, and FIGS. 21B and 22B are rear views of the double-layer gear 452 and the reverse gear 453. FIG. FIG. 21 illustrates a state in which the pair of slide members 420 are disposed at the retracted position. In FIG. 22, the pair of slide members are slid by a predetermined distance from the retracted position, and the engagement protrusion of the reversing gear 453 is illustrated. The state where the end portion of the shape receiving portion 453d is arranged to face the first hollow portion 452b3 of the two-layer gear 452 is illustrated. 21B and 22B, in the double-layer gear 452, the divided gear teeth 452b and the sliding wall portion 452d are illustrated by solid lines, and the gear teeth 452a and the disk portion 452c are illustrated by imaginary lines. The

  As shown in FIG. 21B, in the state where the pair of slide members 420 are disposed at the retracted position, the reverse gear 453 has the arcuate recess 453c of the engagement protrusion receiving portion 453d sliding on the double-layer gear 452. The wall is circumscribed by the wall 452d. Thereby, the posture of the reversing gear 453 can be maintained.

  In this case, the mechanical fitting between the engaging protrusion receiving portion 453d and the sliding wall portion 452d acts as a holding mechanism that maintains the posture of the reversing gear 453. Therefore, it is not necessary to dispose other members such as an elastic spring in order to maintain the posture of the reversing gear 453.

  Further, the sliding wall portion 452d of the two-layer gear 452 and the engagement protrusion receiving portion 453d of the reverse gear 453 are in contact with both sides of a straight line connecting the rotation shaft of the two-layer gear 452 and the rotation shaft of the reverse gear 453. Is done. Therefore, the rotation of the reverse gear 453 can be prevented regardless of the rotation direction of the reverse gear 453, and the posture of the reverse gear 453 can be maintained.

  As shown in FIG. 22B, when the pair of slide members 420 are moved, the transmission gear 451 that meshes with the permanent rack gear 414 a of the base member 410 among the plurality of transmission gears 451 is rotated. Along with the rotation, the other transmission gear 451 and the two-layer gear 452 meshed with the transmission gear 451 by the gear teeth 452 are also rotated. On the other hand, since the reverse gear 453 is not meshed with the double-layer gear 452, it is maintained in the same posture as the retracted position.

  While the pair of slide members 420 are moving, the arc-shaped concave portion 453c of the engagement protrusion receiving portion 453d receives sliding friction from the sliding wall portion 452d of the two-layer gear 452. In the present embodiment, the arcuate concave portion 453c of the engagement protrusion receiving portion 453d is circumscribed on the surface of the sliding wall portion 452d of the two-layer gear 452, thereby suppressing the sliding friction from being concentrated in one place, Frictional force can be dispersed throughout the arcuate recess 453c. Thereby, it is possible to suppress a large force from being applied locally to the reversing gear 453 from the two-layer gear 452. Moreover, the effect of maintaining the posture of the reverse gear 453 can be improved by increasing the number of locations where the two-layer gear 452 and the reverse gear 453 come into contact.

  FIG. 23A and FIG. 23B are rear views of the two-layer gear 452 and the reverse gear 453. FIG. 23 (a) shows a state in which the two-layer gear 452 is rotated by a predetermined amount counterclockwise in the rear view from FIG. 22 (b), and FIG. 23 (b) shows the state of FIG. The state in which the two-layer gear 452 is further rotated by a predetermined amount counterclockwise in the rear view is shown in the figure. In FIG. 23, the split gear teeth 452b and the sliding wall portion 452d are illustrated by solid lines, and the gear teeth 452a and the disk portion 452c are illustrated by imaginary lines.

  As described above with reference to FIG. 22 (b), before the reversing gear 453 is brought into contact with the starting gear teeth 452b1 of the double-layer gear 452, the end of the engaging protrusion receiving portion 453d of the reversing gear 453 is the double-layer gear. The first recess 452b3 of 452 is disposed opposite to the first recess 452b3.

  At this time, since the end of the engagement protrusion receiving portion 453d disposed to face the first recess 452b3 is not in contact with the two-layer gear 452, the effect of maintaining the posture of the reversing gear 453 is released, and at least 1 can be rotated in the direction of rotation (clockwise direction in FIG. 22B).

  As shown in FIG. 23A, the two-layer gear 452 is rotated by a predetermined amount counterclockwise in FIG. 23A, so that the reversing gear 453 is brought into contact with the starting gear teeth 452b1 of the two-layer gear 452. Rotated before That is, the reverse gear 453 is rotated by the sliding friction applied from the sliding wall portion 452d of the double-layer gear 452 to the engaging protrusion receiving portion 453d of the reverse gear 453. At this time, the reversing gear 453 is rotated in such a manner that the engaging protrusion receiving portion 453d enters the first recess 452b3 of the double-layer gear 452.

  That is, the reversing gear 453 is slightly rotated by the sliding friction applied from the sliding wall portion 452d of the two-layer gear 452 to the engaging protrusion receiving portion 453d of the reversing gear 453 (see FIG. 23A). It contacts the starting gear tooth 452b1 of the layer gear 452 (see FIG. 23B). Thereby, the impact when the reversing gear 453 and the starting gear tooth 452b1 of the double-layer gear 452 come into contact with each other can be suppressed.

  As shown in FIG. 23B, the position where the starting gear teeth 452b1 of the two-layer gear 452 and the reversing gear 453 start to contact is a straight line connecting the rotation axis of the two-layer gear 452 and the rotation axis of the reversing gear 453. Rather, it is formed at a position (upward in FIG. 23B) returned to the opposite side of the rotational direction of the double-layer gear 452.

  As a result, the force applied to the reverse gear 453 when the starting gear teeth 452b1 of the double-layer gear 452 and the reverse gear 453 start to contact each other is directed to the rotational direction of the reverse gear 453, and the rotational shaft of the reverse gear 453. It is divided into components that are suitable for Therefore, it is possible to prevent the reverse gear 453 from rotating too much at the start of contact between the start gear teeth 452b1 of the two-layer gear 452 and the reverse gear 453.

  That is, when the starting gear teeth 452b1 of the double-layer gear 452 start to come into contact with the reversing gear 453, they are not meshed with each other by a plurality of teeth from the beginning. Therefore, when the force applied in the rotation direction of the reversing gear 453 when contacting the starting gear teeth 452b1 of the two-layer gear 452 is excessive, the reversing gear 453 rotates at a higher speed than the rotation speed of the two-layer gear 452 ( Move). In that case, there is a possibility that the meshing of the two-layer gear 452 and the reverse gear 453 may fail.

  On the other hand, according to the present embodiment, the force applied from the two-layer gear 452 to the reversing gear 453 at the start of contact is also generated in the direction perpendicular to the rotation direction of the reversing gear 453 (direction toward the rotation axis). The rotational resistance of the reversing gear 453 can be temporarily increased. That is, the rotation resistance can be increased by pressing the reversing gear 453 against the rotation shaft. Thereby, it is possible to prevent the reverse gear 453 from rotating too much at the start of contact of the two-layer gear 452 with the starter gear teeth 452b1.

  Further, since the starting gear teeth 452b1 and 453b1 are formed larger than the gear teeth 452a of the two-layer gear 452, it is possible to prevent tooth disengagement at the start of engagement between the two-layer gear 452 and the reverse gear 453. .

  Here, since the play (backlash) formed becomes larger as the gear teeth become larger, the shift in the positional relationship (phase relationship) between the gears meshed from the middle can be tolerated more greatly as the teeth become larger. become. That is, when the gear teeth are downsized, there is a possibility that the teeth to be engaged will be shifted by one even if the positional relationship (phase relationship) between the gears to be engaged is slightly shifted.

  In this embodiment, the play of the double-layer gear 452 is greater than the play (backlash) generated between the transmission gear 451 to which the drive force of the drive device 470 (see FIG. 10) is transmitted and the gear teeth 452a of the double-layer gear 452. The play (backlash) generated between the start gear teeth 452b1 and the start gear teeth 453b1 of the reverse gear 453 becomes larger. That is, the phase relationship shift of the two-layer gear 452 caused by the relationship with the transmission gear 451 is smaller than the phase relationship shift generated between the two-layer gear 452 and the reversing gear 453 and is acceptable. Thereby, the shift | offset | difference of the tooth | gear at the time of the meshing start of the two-layer gear 452 and the inversion gear 453 can be prevented.

  When the two-layer gear 452 starts to come into contact with the reversing gear 453 in the rotation direction, the starting gear tooth 452b1 of the two-layer gear 452 starts to come into contact with the engaging protrusion receiving portion 453d of the reversing gear 453. That is, the engagement protrusion receiving portion 453d is used as a substitute for the gear tooth that starts to mesh with the starter gear tooth 452b1. Thereby, the durability of the reversing gear 453 can be improved.

  That is, the engagement protrusion receiving portion 453d in which the arc-shaped recess 453c is formed is not a portion that engages with the gear teeth of the two-layer gear 452, but is in contact with the outer peripheral surface of the two-layer gear 452, thereby reversing the gear. This is the part of the role of maintaining the posture of 453. Therefore, the size is not limited according to the size of the mating gear tooth to be engaged, like a gear tooth. In addition, it is desirable that the portion of the double-layer gear 452 that is in contact with the engagement protrusion receiving portion 453d and the reversing gear 453 at the start of contact is large and strong, and the engagement protrusion receiving portion 453d is used as that portion. By using it, the durability of the reversing gear 453 can be improved.

  When the slide member 420 is moved by the driving force of the driving device 470 (see FIG. 10), the transmission gear 451 meshed with the permanent rack gear 414a is rotated, and accordingly, the double-layer gear 452 is rotated. That is, the driving device 470 and the two-layer gear 452 are not directly meshed, and at least the transmitted leg 422 meshed with the driving gear 473 is interposed between the driving device 470 and the two-layer gear 452. To do. Thereby, the impact at the time of contact between the starting gear teeth 452b1 of the two-layer gear 452 and the reverse gear 453 is transmitted to the driving device 470 in a relaxed state. Therefore, it is possible to prevent the driving device 470 from being damaged by an impact at the time of contact.

  24A and 25A are rear views of the composite operation unit 400, and FIGS. 24B and 25B are rear views of the double-layer gear 452 and the reverse gear 453. FIG. 24 shows a state where the pair of meniscus members 460 are rotated by a predetermined amount from the state of FIG. 22A, and FIG. 25 shows the pair of meniscus members 460 from the state of FIG. A state immediately after the rotation by 180 degrees is illustrated. In FIG. 24B and FIG. 25B, the double-layer gear 452 has the divided gear teeth 452b and the sliding wall portion 452d illustrated by solid lines, and the gear teeth 452a and the disk portion 452c illustrated by imaginary lines. The

  As shown in FIG. 24B, in a state where the meniscal member 460 is rotated, the intermediate gear teeth 452b2 of the double-layer gear 452 and the intermediate gear teeth 453b2 of the reverse gear 453 are engaged.

  In the present embodiment, the starting gear teeth 452b1 of the double-layer gear 452 are formed larger than the intermediate gear teeth 452b2. Therefore, the durability of the starting gear teeth 452b1 that abut on the reversing gear 453 at the start of abutting with the reversing gear 453 is improved, and damage to the two-layer gear 452 can be prevented.

  Further, as shown in FIG. 24B, the double-layer gear 452 and the reverse gear 453 are engaged with each other by the intermediate gear teeth 452b2 and 453b2, so that the backlash occurs at the time of continuing the engagement rather than at the start of the engagement. Can be reduced. Thereby, the rotation of the reversing gear 453 when the meshing is continued can be made smooth. Therefore, it is possible to achieve both the improvement of the durability of the starting gear teeth 452b1 colliding at the start of the engagement and the improvement of the smoothness of the rotation of the reversing gear 453.

  Further, since the intermediate gear teeth 452b2 of the two-layer gear 452 are formed smaller than the gear teeth 452a, the intermediate gear teeth 452b2 of the two-layer gear 452 and the intermediate gear teeth 453b2 of the reverse gear 453 are meshed in the circumferential direction. This error (play) is smaller than the meshing error between the gear teeth 452a and the transmission gear 451. As a result, the accuracy of the operation of the reversing gear 453 when the meshing is continued can be maintained below the meshing error between the gear teeth 452a and the transmission gear 451.

  As shown in FIG. 25, when the half-moon member 460 has finished rotating 180 degrees, the engagement between the two-layer gear 452 and the reverse gear 453 is released, and the sliding wall portion 452d of the two-layer gear 452 and the circle of the reverse gear are released. The arc-shaped concave portion 453c is brought into contact with the surface. Therefore, the posture of the reversing gear 453 is maintained, and the locking projection 453e (see FIG. 12) of the reversing gear 453 and the arcuate wall portion 461c (see FIG. 15) are fitted so as not to be relatively rotatable. The attitude is also maintained.

  Next, the operation of the claw member 463 of the meniscal member 460 will be described with reference to FIG. 26A and 26B are partial rear views of the combined operation unit 400. FIG.

  In FIG. 26, the permanent rack gear 414a of the base member 410 is partially omitted, and the limited rack gear 414b is visible and the portion is enlarged. FIG. 26A shows a state immediately before the start gear tooth 441a of the deformed gear 441 contacts the start gear tooth 414b1 of the limited rack gear 414b, and FIG. 26B shows the state in which the slide rack 442 moves. The state of reaching the end is illustrated.

  The meshing between the deformed gear teeth 441 and the limited rack gear 414b becomes defective when the deformed gear 441 is not in contact with the limited rack gear 414b in an appropriate posture. That is, if the deformed gear 441 is in contact with the limited rack gear 414b in a posture in which the start gear teeth 441a of the deformed gear 441 and the start gear teeth 414b1 of the limited rack gear 414b are in contact with each other, a good mesh is achieved. On the other hand, for example, when the gear teeth of the deformed gear 441 other than the start gear teeth 441a and the start gear teeth 414b1 of the limited rack gear 414b are brought into contact with each other, a mesh failure occurs in the middle of the engagement. The rotation of the deformed gear 441 cannot be continued. In this case, the slide movement of the slide member 420 is also stopped, so that the slide member 420 malfunctions.

  In the present embodiment, the slide rack 442 is maintained laterally outward by the biasing force of the biasing spring 442c. The deformed gear 441 receives a force from the slide rack 442 via the transmission gear 443. Therefore, the posture of the deformed gear 441 can be maintained in the appropriate posture described above.

  As shown in FIG. 26B, the deformed gear 441 is engaged with the limited rack gear 414b and rotated, whereby the transmission gear 443 is rotated and the slide rack 442 is moved. The slide rack 442 contacts the drive lever 467 during the movement, and the drive lever 467 rotates. Since the drive lever 467 is fastened and fixed to the center gear 462 (see FIG. 15) of the meniscus member 460, the center gear 462 rotates when the drive lever 467 rotates. As a result, the crank gear 464 is rotated (see FIG. 14), and the claw member 463 is moved in a protruding direction. Therefore, the claw member 463 can be moved in conjunction with the movement of the slide member 420.

  Next, the combined operation unit 2400 according to the second embodiment will be described with reference to FIGS. 27 and 28.

  In the first embodiment, a case has been described in which the notched portion 422d of the transmitted leg 422 is disposed to face the front side of the drive gear 473 in a state where the slide member 420 is disposed at the retracted position. In the combined operation unit 2400, the notch portion 2422 d of the transmitted leg portion 2422 is opposed to the front side of the drive gear 473 while the slide member 2420 moves from the retracted position to the extended position. In addition, the same code | symbol is attached | subjected to the part same as each embodiment mentioned above, and the description is abbreviate | omitted.

  27 and 28 are front views of the pair of slide members 2420. FIG. 27 illustrates a state in which the pair of slide members 2420 are disposed at the retracted position, and FIG. 28 illustrates the start gear teeth 452b1 and the start of the second gear group 450 when the pair of slide members 2420 are moved from the retracted position. A state in which the gear 453b1 (see FIG. 23B) starts to come into contact is illustrated. Further, the illustration of the driving device 470 is omitted for easy understanding.

  As shown in FIG. 27, in a state where the pair of slide members 2420 are disposed at the retracted position, the front side of the drive gear 473 (the front side in FIG. 27) covers the front side in the tooth width direction of the rack gear 422a. The front side wall portion 2422c is overlapped.

  As shown in FIG. 28, the pair of slide members 2420 are arranged at positions where the start gear teeth 452b1 of the double-layer gear 452 and the start gear teeth 453b1 (see FIG. 23B) of the reverse gear 453 start to abut. In the state, the notch portion 2422d is formed on the front side of the drive gear 473 (front side in FIG. 27). The notch portion 2422d is formed in a circular shape slightly larger than the tooth tip circle of the drive gear 473.

  As shown in FIG. 28, the drive gear 473 can be visually recognized in a state of being separated from the outer shape of the notch portion 2422d in the front view (specific phase position). Therefore, the drive gear 473 can be pulled out through the notch portion 2422d formed in the transmitted leg portion 2422, so that the drive gear 473 can be replaced without removing the slide member 2420 from the base member 2410. Therefore, maintainability of the drive gear 473 can be improved.

  In the present embodiment, the specific phase position is set in a state where the pair of slide members 2420 are moved from the retracted position and the start gear teeth 452b1 and the start gear teeth 453b1 (see FIG. 23A) of the second gear group 450 start to contact each other. Therefore, the maintenance worker can move the slide member 2420 to the specific phase position by relying on the increase in resistance when the slide member 2420 is moved.

  That is, when the slide member 2420 is moved, the transmission gear 451 (see FIG. 24A) is always meshed with the permanent rack gear 414a of the base member 2410. Therefore, if the rotation resistance of the transmission gear 451 increases, it can be grasped as the movement resistance of the slide member 2420. Here, since the transmission gear 451 is meshed with the two-layer gear 452, resistance generated when the two-layer gear 452 and the reverse gear 453 start meshing is transmitted to the transmission gear 451. Then, since the resistance of rotation of the transmission gear 451 increases, the movement resistance of the slide member 2420 increases. Thereby, the maintenance worker can move the slide member 2420 to the specific phase position by relying on the movement resistance of the slide member 2420 increasing.

  Here, at the specific phase position, the front side wall portion 2422c does not overlap with the drive gear 473, so that the effect of suppressing the wobbling at the time of rotation of the drive gear 473 by abutting the front side wall portion 2422c with the drive gear 473 is weakened.

  In the present embodiment, a specific phase position (a state in which the notch portion 2422d matches the drive gear 473) is formed while the pair of slide members 2420 are moving, that is, while the drive gear 473 is rotating. Therefore, when the drive gear 473 reaches the specific phase position, the drive gear 473 has a sufficient speed in the rotation direction (axial vertical direction). Therefore, the wobble of the drive gear 473 that tends to occur at the specific phase position can be mitigated by the momentum of the drive gear 473 in the rotational direction.

  The base member 2410 includes a triangular protrusion 2415 that protrudes toward the center side (center side in FIG. 27) in the assembled state. It is possible to easily move the pair of slide members 2420 to the specific phase position by using the triangular protrusion 2415.

  Here, in the maintenance of the gaming machine 13, when the drive motor 472 is removed together with the drive gear 473, the slide member 2420 needs to be arranged at a specific phase position. However, since the drive motor 472 is arranged on the front side so as to hide the slide member 2420 (see FIG. 9), it is difficult to visually recognize the state in which the notch portion 2422d matches the drive gear 473 from the front side. is there. Therefore, it is difficult to arrange the slide member 2420 at the specific phase position.

  On the other hand, since the triangular protrusion 2415 is disposed at a position that can be visually recognized from the front side, it is possible to easily perform the alignment of the slide member 2410 by relying on the triangular protrusion 2415 for maintenance. In the present embodiment, when the pair of slide members 2420 are arranged at a specific phase position, the triangular protrusion 2415 and the triangular pattern formed on the end of the slide member 2420 form a series of patterns. Thereby, it can be made easy for the maintenance worker to remove the drive gear 473 and perform maintenance.

  Next, the two-layer gear 3452 and the reverse gear 3453 in the third embodiment will be described with reference to FIGS. 29 and 30.

  In the first embodiment, the case where the starting gear teeth 452b1 and 453b1 of the double-layer gear 452 and the reversing gear 453 are formed large in the rotational axis direction, that is, the case where the tooth depth and the tooth thickness are increased has been described. The two-layer gear 3452 and the reverse gear 3453 in the third embodiment are formed in a large size in the axial direction while the starter gear teeth 3452b1 and 3453b1 are formed in the same shape as the other gear teeth when viewed in the rotation axis direction. That is, the tooth width is formed large. In addition, the same code | symbol is attached | subjected to the part same as each embodiment mentioned above, and the description is abbreviate | omitted.

  FIG. 29A is a front view of the two-layer gear 3452, FIG. 29B is a bottom view of the two-layer gear 3452, and FIG. 29C is a side view of the two-layer gear 3452. .

  As shown in FIG. 29, the two-layer gear 3452 is disposed adjacent to the sliding wall 452d and has a start gear tooth 3452b1 formed with a large tooth width, and a tooth base side of the start gear tooth 3452b1. A circumferential rib 3452e extending from a circumferential side surface along a concentric circle of the two-layer gear 3452 and fixed to the front end surface of the intermediate gear tooth 452b2 near the starting gear tooth 3452b1, the starting gear; A radial rib 3452f that mainly extends from the radial side surface of the tooth 3452b1 toward the rotation shaft and is fixed to the front end surface of the main body portion of the double-layer gear 3452 is mainly provided.

  The starting gear teeth 3442b1 have substantially the same tooth depth and tooth thickness as the intermediate gear teeth 452b2, but have a larger tooth width than the intermediate gear teeth 452b2. Thereby, the rigidity of the starter gear teeth 3452b1 can be improved, and the starter gear teeth 3452b1 can be prevented from being damaged at the start of meshing with the reversing gear 3453.

  The circumferential rib 3452e is formed to be the widest in the axial direction of the double-layer gear 3452 at the side surface of the start gear tooth 3452b1, that is, the extended base point, and the width is gradually shortened as the distance from the start gear tooth 3452b1 increases. That is, as shown in FIG. 29B, it is visually recognized in a substantially triangular shape when viewed from the bottom. The circumferential rib 3452e can improve the rigidity of the starter gear teeth 3452b along the circumferential direction of the double-layer gear 3452, and can prevent the starter gear teeth 3452b1 from bending in the rotational direction.

  Further, the circumferential rib 3452e extends to the intermediate gear teeth 452b2 in the vicinity of the starter gear teeth 3452b1 (up to two adjacent to the starter gear teeth 3452b1 in this embodiment). Accordingly, it is possible to generate a force that pulls the tooth base of the intermediate gear tooth 452b2 toward the start gear tooth 3452b1 by using the circumferential rib 3452e.

  That is, when the intermediate gear teeth 452b2 and the reverse gear 3453 in the vicinity of the starter gear teeth 3452b1 mesh with each other, deformation (deformation toward the direction away from the starter gear teeth 3352b1) that occurs in the intermediate gear teeth 452b2 is caused by the circumferential rib 3452e. Can be suppressed.

  The circumferential rib 3452e is fixed only to the intermediate gear teeth 452b2 in the vicinity of the starter gear teeth 3452b1 because the intermediate gear teeth 452b2 located away from the starter gear teeth 3452b1 are reversed after the rotation is in a steady state. By meshing with the gear 3453.

  That is, when the intermediate gear tooth 452b2 (for example, the intermediate gear tooth 452b2 near the middle of the pair of starter gear teeth 3352b1) distant from the starter gear tooth 3352b1 is meshed with the reverse gear 3453, the rotation is already in a steady state. The reversing gear 3453 has a sufficient rotational speed. For this reason, the force received by the intermediate gear teeth 452b2 from the reversing gear 3453 is small, and the reinforcement by the circumferential rib 3452e is unnecessary.

  Since the radial rib 3452f extends from the radial side surface of the start gear tooth 3452b1 toward the rotation shaft and is fixed to the front end surface of the main body of the double-layer gear 3452, the start gear tooth The rigidity in the radial direction of 3452b1 can be improved. As a result, the reversing gear 3453 meshed with the two-layer gear 3452 is moved in the axial direction, and the back end (the upper end in FIG. 29 (b)) of the starting gear tooth 3442b1 is forced toward the rotating shaft. Even if it is received, it is possible to prevent the starter gear tooth 3452b1 from falling down. Accordingly, it is possible to improve the durability of the starter gear teeth 3452b1.

  30A is a front view of the reversing gear 3453, FIG. 30B is a bottom view of the reversing gear 3453, and FIG. 30C is a side view of the reversing gear 3453.

  As shown in FIG. 30, the reversing gear 3453 extends along the concentric circle of the reversing gear 3453 from the starting gear tooth 3453b1 adjacent to the arcuate recess 453c and the side surface on the base side of the starting gear tooth 3453b1. And a circumferential rib 3453f fixed to the main body of the reversing gear 3453.

  The start gear tooth 3453b1 has substantially the same tooth width and tooth thickness as the other intermediate gear teeth 453b2, while the tooth width is larger than that of the other intermediate gear teeth 453b2. Thereby, the rigidity of the start gear tooth 3453b1 can be improved.

  The circumferential rib 3453f is formed to be the widest in the axial direction at the side surface of the starting gear tooth 3453b1, that is, at the extended base point, and the width is gradually shortened as the distance from the starting gear tooth 3453b1 increases. That is, as shown in FIG. 30B, it is visually recognized in a substantially triangular shape when viewed from the bottom. The circumferential rib 3453f can prevent the starting gear tooth 3453b1 from being bent in the rotational direction.

  Further, the circumferential rib 3453f extends toward the engaging protrusion receiving portion 453d adjacent to the starter gear tooth 3453b1. As a result, the rigidity of the starter gear teeth 3453b1 with respect to the direction in which force is applied from the two-layer gear 3452 (the direction from the starter gear teeth 3453b1 toward the adjacent engaging projection receiving portion 453d) is improved. Therefore, the durability of the starter gear teeth 3453b1 can be improved.

  Next, with reference to FIGS. 31 and 32, the two-layer gear 4452 and the reverse gear 4453 in the fourth embodiment will be described.

  In the first embodiment, the case where the starting gear teeth 452b1 of the double-layer gear 452 are formed large in the rotational axis direction, that is, the case where the tooth depth and the tooth thickness are increased is described. The double-layer gear 4452 has the start gear teeth 4442b1 formed in the same shape as the other gear teeth in the direction of the rotation axis, while having a large tooth width, and the intermediate gear teeth 4452b2 sandwiched between the start gear teeth 4452b1. The tooth width is formed in such a manner that the tooth width is further shortened as the distance from the starting gear tooth 4442b1 increases. In addition, the same code | symbol is attached | subjected to the part same as each embodiment mentioned above, and the description is abbreviate | omitted.

  FIG. 31A is a front view of the two-layer gear 4452, FIG. 31B is a bottom view of the two-layer gear 4452, and FIG. 31C is XXXIc-XXXXIc of FIG. 31B. FIG. 6 is a cross-sectional view of a two-layer gear 4452 in line.

  As shown in FIG. 31, the double-layer gear 4452 includes a pair of starter gear teeth 4452b1 adjacent to the sliding wall 452d, intermediate gear teeth 4452b2 formed between the starter gear teeth 4452b1, and a starter gear. It mainly includes a plate-like portion 4452e that covers the front side surfaces of the teeth 4452b1 and the intermediate gear teeth 4452b2.

  As shown in FIG. 31 (b), the tooth width of the divided gear tooth 4452b composed of the start gear tooth 4452b1 and the intermediate gear tooth 4452b2 is the maximum in the start gear tooth 4452b1, and the tooth width of the intermediate gear tooth 4452b2 is started. As the distance from the gear teeth 4452b1 increases, the gear teeth 4452b1 are shortened in a stepped manner with reference to the starter gear teeth 4452b1.

  The plate-like portion 4452e is formed so as to project from the tooth bottom side of the divided gear teeth 4452b to a position equivalent to the tooth tip circle in a front view, and is covered on the front side surface of the divided gear teeth 4452b. The plate-like portion 4452e is formed in a mode in which a smooth curve is drawn in a bottom view in accordance with the formation position of the front side surface of the divided gear teeth 4452b (see FIG. 31B).

  Here, a case is considered where the front side surface of the split gear teeth 4452b is formed on the same plane, and the plate-like portion 4452e is also formed on the plane. In this case, the disk portion 452c and the plate-like portion 4552e are used to increase the permissible amount of displacement of the reversing gear 4453 in the axial direction of the two-layer gear 4452 at the start of meshing between the reversing gear 4453 and the two-layer gear 4452. Is increased, the axial position of the rotating reversing gear 4453 cannot be determined. On the other hand, if an attempt is made to accurately determine the axial position of the reversing gear 4453 during rotation, the reversing gear 4453 is slightly displaced in the axial direction at the start of meshing, so that the reversing gear 4453 becomes the outer periphery of the plate-shaped portion 4453e. Contact with the surface may result in poor meshing.

  On the other hand, in the present embodiment, the misalignment in the axial direction (upward in FIG. 31 (b)) that may occur before the reversing gear 4453 is meshed with the double-layer gear 4452 is detected as the meshing start position. It is possible to tolerate as much as possible in the vicinity of the starting gear tooth 4452b1.

  Further, the plate-like portion 4452e is formed in such a manner as to draw a smooth curve in which the distance from the disc portion 452c is shortened as the plate-like portion 4552e is separated from the starting gear teeth 4452b1 in a bottom view (see FIG. 31B). For this reason, the reversing gear 4453 is brought into contact with the plate-like portion 4552e, so that the position of the reversing gear 4453 in the axial direction can be largely corrected as the meshing proceeds (moving downward in FIG. 31 (b)). Can do). Therefore, the positional deviation in the axial direction at the time of meshing between the two-layer gear 4452 and the reverse gear 4453 can be corrected as the meshing progresses.

  32A is a front view of the reversing gear 4453, FIG. 32B is a bottom view of the reversing gear 4453, and FIG. 32C is a view in the direction of arrow XXXIIc in FIG. 32A. 14 is a partial side view of a reversing gear 4453. FIG.

  As shown in FIG. 32, the reversing gear 4453 includes a pair of starter gear teeth 4453b1 disposed adjacent to the pair of arcuate recesses 453c, and an intermediate formed between the starter gear teeth 4453b1. Gear teeth 4453b2.

  As shown in FIG. 32B, the reversing gear 4453 is formed in such a manner that the tooth width of the starting gear tooth 4453b1 is maximized, and the tooth width of the intermediate gear tooth 4453b2 is shortened as the distance from the starting gear tooth 4453b1 increases. . The degree of shortening (inclination of the line connecting the upper ends of the gear teeth in FIG. 32B) is the degree of shortening of the tooth width of the split gear teeth 4452b of the double-layer gear 4452 (each gear tooth in FIG. 31B). (Gradient of the line connecting the upper ends of the two).

  As shown in FIG. 32 (c), the gear teeth 4453b1 and 4453b2 of the reversing gear 4453 are end faces in the width direction except for the intermediate gear teeth 4453b2 formed farthest from the pair of engaging projection receiving portions 453d. (FIG. 32 (b) upper end surface) is formed so as to be inclined downward toward the engagement protrusion receiving portion side. As a result, the displacement can be corrected more rapidly while maintaining a large allowable amount of relative displacement in the axial direction at the start of meshing between the reversing gear 4453 and the double-layer gear 4452.

  That is, when the gear teeth 4453b1 and 4453b2 of the reversing gear 4453 are meshed with the two-layer gear 4452, the gear teeth 4453b1 and 4453b2 are on the engagement protrusion receiving portion side (the tooth width is the shortest side, FIG. 32C). Start meshing from the right). Therefore, for example, compared with the case where the dimension in the tooth width direction of each gear tooth 4453b1 and 4453b2 is constant on the tooth width longest side (left side in FIG. 32 (c)), A large space (play) between the gear teeth 4453b1 and 4453b2 can be secured. Therefore, a large allowable amount of positional deviation in the axial direction at the start of meshing between the reversing gear 4453 and the double-layer gear 4452 can be secured.

  On the other hand, when the meshing between the gear teeth 4453b1 and 4453b2 of the reversing gear 4453 and the double-layer gear 4452 proceeds, the longest tooth width side (the left side in FIG. 32 (c)) of each gear tooth 4453b1 and 4453b2 It enters into the back side of plate-like part 4452e (the lower part of Drawing 31 (b)). Thereby, for example, compared with the case where the dimension in the tooth width direction of each gear tooth 4453b1 and 4453b2 is constant on the tooth width shortest side (the right side in FIG. 32 (c)), the meshing is released (the teeth of each other are The distance (play) between the immediately preceding plate-like portion 4452e and the gear teeth 4453b1 and 4453b2 can be reduced.

  Therefore, when each gear tooth 4453b1 and 4453b2 meshes with the two-layer gear 4452, between the start of meshing for each gear tooth 4453b1 and 4453b2 and the meshing release, between the plate-shaped portion 4453e and each gear tooth 4453b1 and 4453b2 The interval (play) can be reduced. This makes it possible to correct the misalignment between the reversing gear 4453 and the two-layer gear 4452 more rapidly.

  Further, in the present embodiment, the inclination of the plate-like portion 4452e (see FIG. 31B) is formed in the opposite direction to the inclination of the gear teeth 4453b1 and 4453b2 of the reversing gear 4453 (see FIG. 32C). Further, it is possible to improve the effect of making the correction of the misalignment more abrupt while maintaining a large allowable amount of misalignment in the axial direction at the start of meshing between the reversing gear 4453 and the double-layer gear 4452 described above.

  Note that the end face in the width direction (upper end face in FIG. 32 (b)) of the intermediate gear teeth 4453b2 formed farthest from the pair of engaging projection receiving parts 453d is formed by a plane perpendicular to the rotation axis of the reversing gear 4453. The

  Next, the second gear group 5450 in the fifth embodiment will be described with reference to FIGS. 33 to 35.

  In the first embodiment, the case where the two-layer gear 452 is formed of only a single resin material has been described. However, the two-layer gear 5452 in the fifth embodiment has a magnetic material embedded in the starter gear teeth 5452b1. The In addition, the same code | symbol is attached | subjected to the part same as each embodiment mentioned above, and the description is abbreviate | omitted.

  FIG. 33 is a front view of the two-layer gear 5452. As shown in FIG. 33, in the double-layer gear 5452, an embedding hole 5452g is formed in the starting gear tooth 5452b1 along a direction parallel to the rotation axis, and an embedding member 5452h is embedded in the embedding hole 5452g.

  The embedded hole 5452g is formed in a bottomed hole shape having a circular cross section, and the embedded member 5452h is formed in a columnar shape having a diameter that is the same as or slightly larger than the diameter of the embedded hole 5452g. As a result, the embedded member 5452h is fitted and fixed in the embedded hole 5452g.

  The embedded member 5452h is a cylindrical member formed of a metal magnetic material or a plastic magnetic material, and the S pole and the N pole are divided into two parts along a plane along the axis. In FIGS. 33 to 35, the black side of the embedded member 5452h is formed with the N pole, and the opposite side is formed with the S pole.

  FIG. 34 is a partial front view of the second gear group 5450. FIG. 34 shows a state immediately before the starting gear teeth 5542b1 of the double-layer gear 5252 abuts on the engaging protrusion receiving portion 453d of the reversing gear 5453. In addition, the disk portion 452c and gear teeth 452a of the double-layer gear 5452 and the transmission gear 451 are illustrated by imaginary lines.

  As shown in FIG. 34, in the reversing gear 5453, an embedding hole 5453f is formed in the starting gear tooth 5453b1 along a direction parallel to the axis, and an embedding member 5453g is embedded in the embedding hole 5453f. Thereby, the embedded member 5453g is fitted and fixed in the embedded hole 5453f.

  The embedded member 5453g is a cylindrical member formed of a metal magnetic material or a plastic magnetic material, and the S pole and the N pole are divided into two parts in a plane along the axis.

  As shown in FIG. 34, the plane that divides the magnetic pole into two is formed along the radial direction and passes through the axis, and the starter gear teeth 5452b1 and 5453b1 are embedded with the opposite poles facing each other. That is, the starter gear tooth 5453b1 is formed with an N pole on the side (upper side in FIG. 34) facing the starter gear tooth 5453b1 when engaged, and the starter gear tooth 5453b1 is on the side (lower side in FIG. 34) facing the starter gear tooth 5252b1. S pole is formed on the side). Thereby, in the meshing of the two-layer gear 5452 and the reverse gear 5453, a magnetic force that attracts the meshing gear teeth 5452b1 and 5453b1 is generated.

  That is, as the double-layer gear 5452 is rotated counterclockwise in FIG. 34 from the state shown in FIG. 34, the distance between the embedding members 5452h and 5453g is shortened, so that the magnetic force generated between them increases, and the start gear teeth 5453b1 Attracted to 5452b1. As a result, the reversing gear 5453 is rotated by the magnetic force and rotated before the starting gear teeth 5452b1 of the double-layer gear 5452 and the engaging projection receiving portion 453d of the reversing gear 5453 come into contact with each other. Therefore, as compared with the case where the start gear teeth 5452b1 are in contact with the reversing gear 5453 in the stationary state, the impact at the time of contact and the load received by the two-layer gear 5452 and the reversing gear 5453 at the time of contact can be reduced.

  FIG. 35 is a partial front view of second gear group 5450. FIG. 35 shows a state in which the two-layer gear 5452 is rotated counterclockwise by a predetermined amount from the state of FIG. In addition, the disk portion 452c and gear teeth 452a of the double-layer gear 5452 and the transmission gear 451 are illustrated by imaginary lines.

  As shown in FIG. 35, a gap is formed between the two-layer gear 5452 and the reverse gear 5453 in front of the two-layer gear 5453 in the rotation direction. As a result, the load applied to the engagement protrusion receiving portion 453d not only when the contact between the two-layer gear 5452 and the reverse gear 5453 is started but also while the two-layer gear 5452 and the reverse gear 5453 are rotated by meshing. Can be suppressed. Therefore, the strength required for the engaging protrusion receiving portion 453d can be reduced, and the degree of freedom in designing the engaging protrusion receiving portion 453d can be improved.

  Next, the second gear group 6450 in the sixth embodiment will be described with reference to FIGS. 36 and 37.

  In the first embodiment, the case where the two-layer gear 452 is integrally formed has been described. However, the two-layer gear 6452 in the sixth embodiment omits the starting gear teeth 452b1 and is different from the intermediate gear teeth 452b2. The body is provided with a deformed gear tooth member 6452g. In addition, the same code | symbol is attached | subjected to the part same as each embodiment mentioned above, and the description is abbreviate | omitted.

  FIG. 36 is a front exploded perspective view of the two-layer gear 6452. FIG. 36 shows a state in which the deformed gear tooth member 6452g is removed from the disc portion 452c. In the present embodiment, the deformed gear tooth member 6452g is formed of a metal material such as iron, so that it is a portion other than the deformed gear tooth member 6452g of the two-layer gear 6452 and a portion integrally formed from a resin material. Thus, the rigidity of the deformed gear tooth member 6452g is increased. Further, by partially using a metal material, the weight of the two-layer gear 6452 can be reduced as compared with the case where the entire two-layer gear 6452 is formed of a metal material, and the driving force required to rotate the two-layer gear 6452 can be suppressed. it can.

  As shown in FIG. 36, the double-layer gear 6452 includes a pair of deformed gear tooth members 6452g, a hole through which the deformed gear tooth member 6452g is inserted, and a hole 6452c1 formed in the disc portion 452c. A gear tooth side notch 6452b5 that is a notch formed between the first recess 452b3 and the second recess 452b4 and into which the gear tooth main body 6452g1 of the deformed gear tooth member 6452g is sandwiched, and a sliding wall 452d. The sliding part notch 6452d1 between which the sliding receiving part 6452g3 of the deformed gear tooth member 6452g is sandwiched and the flanges formed in the L-shaped saddle shape at both ends of the sliding wall part 452d The mold receiving part 6452d2 is mainly provided.

  The deformed gear tooth member 6452g includes a gear tooth main body portion 6452g1 having a shape obtained by extending the starting gear tooth 452b1 in the first embodiment toward the tooth bottom side, and a back surface from an end opposite to the tooth tip of the gear tooth main body portion 6452g1. A cylindrical insertion pin 6452g2 projecting on the side, a sliding receiving portion 6452g3 whose side surface forms part of the sliding wall portion 452d in the assembled state (see FIG. 37), and a gear tooth main body portion 6452g1. It mainly includes a connecting portion 6452g4 that connects the receiving portion 6452g3.

  The gear tooth main body portion 6452g1 is formed such that the tooth thickness of the portion sandwiched between the gear tooth side notches 6452b5 is equal to or slightly larger than the dimension of the gear tooth side notches 6452b5. Thus, the gear tooth main body portion 6452g1 is sandwiched between the gear tooth side notches 6452b5 in the assembled state (see FIG. 37).

  The sliding receiving portion 6452g3 is formed in a state where the outer peripheral surface is smoothly connected to the outer peripheral surface of the sliding wall portion 452d in the assembled state (see FIG. 37). The outer peripheral surface of the connecting portion 6452g4 is disposed opposite the recessed bottom wall portion 452e in an assembled state (see FIG. 37) with a slight gap.

  In the assembled state (see FIG. 37), the insertion pin 6452g2 is inserted through the insertion hole 6452c1, and the gear tooth main body portion 6452g1 is sandwiched between the gear tooth side cutouts 6452b5. Further, the connecting portion 6452g4 is disposed to face the recessed bottom wall portion 452e of the second recessed portion 452b4 with a slight gap, and the inner peripheral side of the sliding receiving portion 6452g3 is in contact with the saddle-shaped receiving portion 6452d2. As a result, the rotation amount of rotation about the insertion hole 6452c1 can be suppressed by the gear tooth main body 6452g1 coming into contact with the reversing gear 453.

  FIG. 37 is a front view of the double-layer gear 6452 and the reverse gear 453. In FIG. 37, a state in which the gear tooth main body portion 6452g1 of the deformed gear tooth member 6452g is in contact with the engagement protrusion receiving portion 453d of the reverse gear 453 is illustrated, and the disk portion 452c is illustrated by an imaginary line. Is done.

  As shown in FIG. 37, the load applied by the deformed gear tooth member 6452g from the reversing gear 453 can be received by the engaging protrusion receiving portion 453d of the reversing gear 453.

  That is, even if the deformed gear tooth member 6452g is formed from a metal material, the portion that supports the deformed gear tooth member 6452g is formed from a resin material. In addition, the two-layer gear 6452 is not sufficiently rigid because the radial thickness is formed to be substantially constant in order to prevent the occurrence of sink marks during molding. Therefore, when the deformed gear tooth member 6452g moves (rotates about the insertion hole 6452c1) due to a load generated when the two-layer gear 6452 and the reverse gear 453 come into contact with each other, a pressing force is applied from the deformed gear tooth member 6452g. There is a risk that parts other than the deformed gear tooth member 6452g (such as the hollow bottom wall 452e) receiving the damage may be damaged.

  On the other hand, in the present embodiment, the deformed gear tooth member 6452g starts to move in a direction to fill a slight gap formed between the outer peripheral surface of the coupling portion 6452g4 and the hollow bottom wall portion 452e (with the insertion hole 6452c1 as an axis). When the rotation starts, the slide receiving portion 6452g3 of the deformed gear tooth member 6452g is pressed against the arc-shaped recess 453c of the reverse gear 453. The arc-shaped recess 453c is a portion having a sufficient radial thickness and a large rigidity.

  As a result, the load applied by the deformed gear tooth member 6452g from the reversing gear 453 can be received by the engaging protrusion receiving portion 453d of the reversing gear 453, and is a portion of the double-layer gear 6452 and other than the deformed gear tooth member 6452g. The load applied to the portion (the bottom wall portion 452e, etc.) can be suppressed. Further, the deformed gear tooth member 6452g can be supported using the arcuate recess 453c of the reversing gear 453.

  Next, with reference to FIGS. 38 to 45, the combined operation unit 7400 in the seventh embodiment will be described.

  In the first embodiment, the case where the position of the slide member 420 when the meniscus member 460 rotates is limited to one way. However, the combined operation unit 7400 according to the seventh embodiment is configured to rotate the meniscus member 460. The slide member 420 can be formed in at least two positions. In addition, the same code | symbol is attached | subjected to the part same as each embodiment mentioned above, and the description is abbreviate | omitted.

  FIG. 38A to FIG. 38C are rear views of the two-layer gear 7452. FIG. 38A shows a stationary state in which the rotation of the two-layer gear 7452 is stopped, and FIG. 38B shows a first rotation in which the rotation speed V of the two-layer gear 7452 is lower than the boundary speed Vb. A state in which the speed is V1 is illustrated, and in FIG. 38C, a state in which the rotational speed V of the two-layer gear 7452 is the second rotational speed V2 higher than the boundary speed Vb is illustrated.

  In order to facilitate understanding, the gear teeth 452a and the disk portion 452c are not shown. The same applies to the subsequent drawings. Further, the boundary speed Vb means the rotational speed V of the two-layer gear 7452 when the protruding gear member 7452e is switched from the immersive state to the overhanging state.

  As shown in FIG. 38, the two-layer gear 7452 is formed with a guide groove 7452d that is a groove having a rectangular cross section formed radially outward from the rotation shaft, and a width that is slightly smaller than the groove width of the guide groove 7452d. And a projecting gear member 7452e whose tip is formed in a gear tooth shape, and a biasing spring 7452f that couples the projecting gear member 7452e and the rotating shaft of the two-layer gear 7452.

  The guide groove 7452d is formed at three locations by arranging the outer periphery of the two-layer gear 7452 into three equal parts in the circumferential direction, and a protruding gear member 7452e and a biasing spring 7452f are provided in each guide groove 7452d. Further, intermediate gear teeth 452b2 are formed on the outer peripheral surface of the double-layer gear 7452 connecting the guide grooves 7452d.

  In the protruding gear member 7452e, the protruding gear members 7452e1 to 7451e3 are formed with the same mass, and the urging springs 7452f are formed with the same spring constant.

  As shown in FIG. 38A, when the two-layer gear 7452 is in a stopped state, the protruding gear member 7452e is immersed closer to the rotating shaft than the surface where the bottoms of the intermediate gear teeth 452b2 are connected. At this time, the incorrect spring 7452f has a natural length.

  As shown in FIG. 38B, when the two-layer gear 7452 is rotated at the first rotation speed V1 lower than the boundary speed Vb, the protruding gear member 7452e is moved outward in the radial direction of the two-layer gear 7452. Force to do. The protruding gear member 7452e is extended to a position where the force and the urging force by the urging spring 7452f are balanced. In the overhanging state, the protruding gear member 7452e is positioned closer to the rotating shaft than the surface where the tooth tips of the intermediate gear teeth 452b2 are connected (immersion state).

  Therefore, as will be described later, when the double-layer gear 7452 is rotated at the first rotational speed V1, the double-layer gear 7453 does not start meshing with the reverse gear 7453 (see FIG. 42). In other words, the two-layer gear 7452 rotates idly with respect to the reverse gear 7453.

  As shown in FIG. 38C, when the two-layer gear 7452 is rotated at the second rotational speed V2 higher than the boundary speed Vb, the protruding gear member 7452e is moved outward in the radial direction of the two-layer gear 7452. Force to do. The protruding gear member 7452e is extended to a position where the force and the urging force by the urging spring 7452f are balanced. In the overhanging state, the protruding gear member 7452e is overhanging radially outward from the surface where the tooth tips of the intermediate gear teeth 452b2 are connected.

  Therefore, as will be described later, when the two-layer gear 7452 is rotated at the second rotational speed V2, the projecting gear member 7452e of the two-layer gear 7452 abuts on the reverse gear 7453 (see FIG. 39), thereby The layer gear 7452 starts to mesh with the reverse gear 7453.

  That is, whether or not the two-layer gear 7452 starts to mesh with the reversing gear 7453 (see FIG. 39) depending on whether the rotational speed V of the two-layer gear 7452 is higher or lower than the boundary speed Vb. You can choose. Therefore, the half-moon member 460 (see FIG. 40) is obtained by changing the rotational speed V of the double-layer gear 7452 during the rotation (by changing the moving speed of the slide member 420 (see FIG. 40) during the movement). A plurality of variations of the arrangement of the slide member 420 when the is rotated can be prepared.

  Next, variations in the arrangement of the slide member 420 when the meniscus member 460 begins to rotate will be described with reference to FIGS. 39 to 44. First, with reference to FIGS. 39 to 41, the case where the main drive gear 7452 is rotated at the second rotational speed V2 immediately after the movement member 420 starts to move from the retracted position (first speed pattern) will be described.

  39 (a) to 39 (e) are rear views of the double-layer gear 7452 and the reverse gear 7453 illustrating the rotation of the double-layer gear 7452 and the reverse gear 7453 in time series, and FIG. 40 (a) and FIG. 40 (b), FIG. 41 (a), and FIG. 41 (b) are front views of the composite operation unit 7400 that illustrates the slide movement of the slide member 420 and the posture change of the meniscal member 460 in time series. For ease of understanding, the gear teeth 452a and the disk portion 452c are not shown in FIG. 39, and the fastening plate portion 471 and the drive motor 472 are not shown in FIGS. 40 and 41.

  39 (a) and FIG. 40 (a), FIG. 39 (b) and FIG. 40 (b), FIG. 39 (c) and FIG. 41 (a), and FIG. 39 (d) and FIG. 41 (b). Are diagrams of substantially simultaneous points, which correspond to each other. Also, in FIG. 39, the rotation direction of the two-layer gear 7452 is shown by an arrow, and as shown in FIG. 39, the arc-shaped recess 453c is circumscribed by a circle connecting the tooth tips of the intermediate gear teeth 452b2 of the two-layer gear 7452. It is formed in the mode.

  As shown in FIG. 39A, the double-layer gear 7452 is rotated at the second rotational speed V2 immediately after the start of movement of the slide member 420 (see FIG. 40A), and the double-layer gear 7452 is rotated by a predetermined amount. The first protruding gear member 7452e1 is brought into contact with the engaging protruding receiving portion 453d of the reversing gear 7453 (see FIG. 39B). Thereby, the reverse gear 7453 starts to rotate, and the half-moon member 460 starts to change its posture (see FIG. 40B).

  After the reversing gear 7453 starts to rotate, the intermediate gear teeth 452b2 of the double-layer gear 7453 and the intermediate gear teeth 453b2 of the reversing gear 7453 are engaged with each other, whereby the rotation of the reversing gear 7453 is continued and the posture change of the half-moon member 460 is performed. Is continued (see FIG. 39 (c) and FIG. 41 (a)).

  After the intermediate gear teeth 452b2 of the two-layer gear 7452 and the intermediate gear teeth 453b2 of the reversing gear 7453 mesh with each other, the two-layer gear 7452 is further rotated, so that the arc-shaped recess 453c of the reversing gear 7453 is again re-layered. (See FIG. 39D), the rotation of the reverse gear 7453 is stopped, and the posture of the meniscal member 460 with respect to the slide member 420 is fixed (see FIG. 41B).

  Thereafter, the two-layer gear 7452 is rotated until the slide member 420 finishes sliding (see FIG. 26B), and the rotation is stopped when the slide member 420 is stopped (see FIG. 39E). Thereafter, the projecting gear member 7452e is moved inward in the radial direction of the two-layer gear 7452 by the biasing force of the biasing spring 7452f.

  Here, when the two-layer gear 7452 is rotated from the state shown in FIG. 39D to the state shown in FIG. 39E, the third projecting member 7452e3 and the first projecting member 7452e1 are brought into contact with the engaging projecting receiving portion 453d. There is a risk that the two-layer gear 7452 and the reversing gear 7453 will mesh again.

  On the other hand, in the present embodiment, an arc-shaped chamfered portion 7453e is formed at one end (the upper end in FIG. 39 (e)) of the engaging protrusion receiving portion 453d.

  When the third projecting member 7452e3 and the first projecting member 7452e1 are brought into contact with the chamfered portion 7453e, a force directed to the inner side in the radial direction of the two-layer gear 7452 is applied to the third projecting member 7452e3 and the first projecting member 7452e1. Thereby, before the 3rd protrusion member 7452e3 and the 1st protrusion member 7452e1 mesh | engage with the inversion gear 745, the 3rd protrusion member 7452e3 and the 1st protrusion member 7452e1 can be made into an immersion state, respectively. Therefore, it is possible to prevent the double-layer gear 7452 and the reverse gear 7453 from meshing again.

  Next, referring to FIGS. 42 to 44, immediately after the movement of the moving member 420 from the retracted position, the two-layer gear 7452 is rotated at the first rotation speed V1, and the two-layer gear 7452 is rotated second during the rotation. A case (second speed pattern) in which rotation is performed at the speed V2 (the rotation speed V is changed) will be described.

  42 (a) to 42 (e) are rear views of the two-layer gear 7452 and the reverse gear 7453 illustrating the rotations of the two-layer gear 7452 and the reverse gear 7453 in time series, and FIG. 43 (a) and FIG. 43 (b), FIG. 44 (a), and FIG. 44 (b) are front views of the combined operation unit 7400 that illustrates the slide movement of the slide member 420 and the posture change of the meniscal member 460 in time series. For ease of understanding, the gear teeth 452a and the disk portion 452c are not shown in FIG. 42, and the fastening plate portion 471 and the drive motor 472 are not shown in FIGS. 43 and 44.

  42 (a) and FIGS. 40 (a), 42 (b) and 43 (a), 42 (c) and 43 (b), 42 (d) and 44 (a). ), And FIG. 42 (e) and FIG. 44 (b) are diagrams of substantially simultaneous points, which correspond to each other. In FIG. 42, the rotation direction of the double-layer gear 7452 is indicated by an arrow. As shown in FIG. 42 (a), the arc-shaped recess 453c is a circle formed by connecting the tooth tips of the intermediate gear teeth 452b2 of the double-layer gear 7452. Formed in a circumscribed manner.

  As shown in FIG. 42 (a), the double-layer gear 7452 is rotated at the first rotation speed V1 immediately after the start of the movement of the slide member 420 (see FIG. 40 (a)). Form.

  Therefore, even if the two-layer gear 7452 is rotated by a predetermined amount, the first projecting gear member 7452e1 is not brought into contact with the engagement protrusion receiving portion 453d of the reversing gear 7453, and therefore the meshing between the two-layer gear 7452 and the reversing gear 7453 is It is not started (see FIG. 42B). Thereby, the slide member 420 is moved while the posture of the half-moon member 460 is maintained (see FIG. 43A).

  The rotation speed V of the two-layer gear 7452 is changed to the second rotation speed V2 until the second-layer gear 7452 continues to rotate and the second protruding gear member 7452e2 approaches the engagement protrusion receiving portion 453d of the reverse gear 7453. Is done. As a result, the protruding gear member 7452e forms an overhanging state (see FIG. 42C), and the reversing gear 7453 is rotated by the second protruding gear member 7452e2 coming into contact with the engaging protruding receiving portion 453d. At the same time, the half-moon member 460 starts to change its posture (see FIG. 43B).

  After the reversing gear 7453 starts to rotate, the intermediate gear teeth 452b2 of the double-layer gear 7453 and the intermediate gear teeth 453b2 of the reversing gear 7453 are engaged with each other, whereby the rotation of the reversing gear 7453 is continued and the posture change of the half-moon member 460 is performed. (See FIG. 42D and FIG. 44A).

  After the intermediate gear teeth 452b2 of the two-layer gear 7452 and the intermediate gear teeth 453b2 of the reversing gear 7453 mesh with each other, the two-layer gear 7452 is further rotated, so that the arc-shaped recess 453c of the reversing gear 7453 is again re-layered. (See FIG. 42E), the rotation of the reverse gear 7453 is stopped, and the posture of the meniscal member 460 with respect to the slide member 420 is fixed (see FIG. 44B).

  Thereafter, the two-layer gear 7452 is rotated until the slide member 420 finishes sliding (see FIG. 26B), and the rotation is stopped when the slide member 420 is stopped.

  Since the rotational speed V of the two-layer gear 7452 and the moving speed of the slide member 420 are proportional, it is easy to change the rotational speed V of the two-layer gear 7452 by changing the rotational speed of the drive motor 472. Can be done.

  Thus, according to the present embodiment, the position of the slide member 420 is changed at least in two ways when the half-moon member 460 starts to rotate while the slide member 420 is slid from the retracted position to the extended position. be able to. That is, compared with the case where the double-layer gear 7452 is rotated at the second rotation speed V2 from the start of rotation (see FIGS. 39 to 41), the first rotation speed V1 is changed to the second rotation speed V2 during the rotation. When changed (see FIGS. 42 to 44), the arrangement of the slide member 420 when the meniscal member 460 rotates can be moved to the center side (vertical center side) (FIG. 40B and FIG. 43 (b)). Thereby, the variation of production can be increased.

  Next, representative examples of the first speed pattern and the second speed pattern described above will be described with reference to FIG. FIG. 45 is a graph showing changes in the speed of the two-layer gear 7452. 45, the horizontal axis indicates the position (P) of the slide member 420 between the retracted position (P = 0) and the extended position (P = Pmax), and the vertical axis indicates the slide of the slide member 420. The rotational speed V of the double-layer gear 7451 that is rotated during movement is shown.

  In the horizontal axis of FIG. 45, the first position P1 means a position (see FIG. 39B) where the first projecting gear member 7452e1 is initially arranged to face the reversing gear 7453, and the second position P2 is , The second protruding gear member 7452e2 is the position where the first reverse gear 7453 is opposed to the first position (FIG. 42C). The solid line indicates the first speed pattern described above, and the broken line indicates the second speed pattern described above. Indicated.

  As described above, in the present embodiment, when the two-layer gear 7452 is rotated at the first speed pattern, the posture of the half moon member 460 starts to change immediately after the slide member 420 reaches the first position P1. On the other hand, when the double-layer gear 7452 is rotated at the second speed pattern, the half-moon member 460 starts to change its posture immediately after the slide member 420 reaches the second position P2.

  That is, by changing the rotational speed V of the double-layer gear 7452 during the sliding movement of the sliding member 420, the position of the sliding member 420 when the posture of the meniscus member 460 starts to change can be changed. Therefore, variations in the effects of the slide member 420 and the half moon member 460 can be increased.

  Next, the combined operation unit 8400 in the eighth embodiment will be described with reference to FIGS. 46 to 48.

  In the seventh embodiment, the case where the position of the slide member 420 is changed when the half-moon member 460 is rotated by changing the rotation speed V of the double-layer gear 7452 in the middle of the rotation has been described. The combined operation unit 8400 is formed such that the position of the slide member 420 when the meniscus member 460 rotates can be changed while the rotation speed of the double-layer gear 8452 is maintained at a constant speed. In addition, the same code | symbol is attached | subjected to the part same as each embodiment mentioned above, and the description is abbreviate | omitted.

  46 (a) and 46 (b) are rear views of the two-layer gear 8452. FIG. 46A shows a state in which the two-layer gear 8452 is rotated at the separation rotational speed V3, and FIG. 46B shows a state in which the two-layer gear 8452 is rotated at the common rotational speed V4. Is done. The stationary state in which the rotation of the two-layer gear 8452 is stopped is the same as that in FIG.

  In order to facilitate understanding, the gear teeth 452a and the disk portion 452c are not shown. The same applies to the subsequent drawings. Further, the separation rotation speed V3 means a rotation speed at which the first protruding gear member 7452e1 forms an immersive state while the second protruding gear member 7452e2 forms an overhanging state, and the joint rotation speed V4 means the first rotation speed V4. It means a rotation speed at which the first protruding gear member 7451e1 and the second protruding gear member 7452e2 together form an overhanging state.

  As shown in FIG. 46 (a), when the two-layer gear 8452 is rotated at the separation rotational speed V3, the protruding gear members 7452e are moved outward in the radial direction of the two-layer gear 8252 with different overhang amounts. (At least the second protruding gear member 7452e2 has a larger movement amount than the first protruding gear member 7452e1).

  In the present embodiment, the spring constants of the urging springs 8452f that connect the protruding gear members 7452e and the rotation shafts of the two-layer gears 7452 are different from each other. That is, the spring constant of the first biasing spring 8452f1 that connects the first projecting gear member 7452e1 and the rotation shaft of the two-layer gear 8452 is the first that connects the second projecting gear member 7452e2 and the rotation shaft of the two-layer gear 8452. It is made larger than the spring constant of the 2 biasing springs 8452f2. Note that the spring constant of the third biasing spring 8452f3 is larger than the spring constant of the first biasing spring 8452f1.

  As shown in FIG. 46 (a), when the two-layer gear 7452 is rotated at the separation rotational speed V3, the first projecting gear member 7452e1 is positioned closer to the rotation shaft than the surface connecting the tooth tips of the intermediate gear teeth 452b2. Then, the second projecting gear member 7452e2 projects outward in the radial direction from the surface where the tooth tips of the intermediate gear teeth 452b2 are connected (extended state).

  Therefore, as will be described later, when the double-layer gear 8452 is rotated at the separation rotational speed V3, the double-layer gear 8252 does not start meshing with the reversing gear 7453 in the first protruding gear member 7452e1, but the second protruding gear. The member 7452e2 meshes with the reverse gear 7453.

  As shown in FIG. 46B, when the two-layer gear 8452 is rotated at the joint rotation speed V4, a force is generated to move the protruding gear member 7452e outward in the radial direction of the two-layer gear 8452. The protruding gear member 7452e is extended to a position where the force and the urging force by the urging spring 8452f are balanced. In the projecting state, at least the first projecting gear member 7452e1 and the second projecting gear member 7452e2 are projecting radially outward from the surface where the tooth tips of the intermediate gear teeth 452b2 are connected (projected state).

  Therefore, when the two-layer gear 8452 is rotated at the joint rotation speed V4, the first projecting gear member 7252e1 of the projecting gear member 7451e of the two-layer gear 8452 abuts on the reversing gear 7453, whereby the two-layer gear 7452 is obtained. Begins to mesh with the reversing gear 7453.

  The operations of the two-layer gear 8452, the reversing gear 7453, and the slide member 420 when the two-layer gear 8452 is rotated at a constant speed at the common rotation speed V4 are the same as the operations illustrated in FIGS. Description is omitted.

  47 (a) to 47 (e) are rear views of the two-layer gear 8452 and the reverse gear 7453 illustrating the rotation of the two-layer gear 8452 and the reverse gear 7453 in time series. In the description of FIG. 47, FIGS. 40, 43, and 44 are referred to as appropriate, and in FIG. 47, the gear teeth 452a and the disk portion 452c are not shown for easy understanding.

  Note that FIG. 47 (a) and FIGS. 40 (a), 47 (b) and 43 (a), 47 (c) and 43 (b), FIG. 47 (d) and FIG. ), And FIGS. 47 (e) and 44 (b) are diagrams of substantially simultaneous points, which are in correspondence with each other. In FIG. 47, the rotation directions of the double-layer gear 8452 and the reverse gear 7453 are illustrated by arrows, and the arc-shaped recess 453c is connected to the teeth of the intermediate gear teeth 452b2 of the double-layer gear 8452 as shown in FIG. It is formed so as to be circumscribed by a circle.

  As shown in FIG. 47 (a), the double-layer gear 8452 is rotated at the separation rotational speed V3 immediately after the start of the movement of the slide member 420 (see FIG. 40 (a)), so that the first protruding gear member 7452e1 is in the immersed state. And the second protruding gear member 7452e2 forms an overhanging state.

  Therefore, even if the two-layer gear 8452 is rotated by a predetermined amount, the first projecting gear member 7452e1 is not brought into contact with the engagement protrusion receiving portion 453d of the reversing gear 7453. It is not started (see FIG. 47 (b)). Thereby, the slide member 420 is moved while the posture of the half-moon member 460 is maintained (see FIG. 43A).

  The double-layer gear 8452 continues to rotate at the separation rotational speed V3, the second projecting gear member 7452e2 comes into contact with the engaging projecting receiving portion 453d, the reversing gear 7453 begins to rotate, and the meniscal member 460 is in the posture. It starts to change (see FIG. 43 (b)).

  After the reversing gear 7453 starts to rotate, the intermediate gear teeth 452b2 of the double-layer gear 8452 and the intermediate gear teeth 453b2 of the reversing gear 7453 mesh with each other, so that the rotation of the reversing gear 7453 continues and the posture change of the half-moon member 460 Is continued (see FIG. 47 (d) and FIG. 44 (a)).

  After the intermediate gear teeth 452b2 of the two-layer gear 8452 and the intermediate gear teeth 453b2 of the reversing gear 7453 are engaged with each other, the two-layer gear 8452 is further rotated, so that the arc-shaped recess 453c of the reversing gear 7453 is again formed by the two-layer gear 8452. (See FIG. 47E), the rotation of the reverse gear 7453 is stopped, and the posture of the meniscal member 460 is fixed (see FIG. 44B).

  Thereafter, the double-layer gear 8452 is rotated until the slide member 420 finishes sliding (see FIG. 26B), and the rotation is stopped when the slide member 420 is stopped.

  Thus, according to the present embodiment, the position of the slide member 420 is changed at least in two ways when the half-moon member 460 starts to rotate while the slide member 420 is slid from the retracted position to the extended position. Therefore, the speed change during the slide movement of the slide member 420 is not required.

  That is, compared with the case where the double-layer gear 8452 is rotated at a constant speed at the joint rotation speed V4 (see FIGS. 40 and 41), the double-layer gear 8452 is rotated at a constant speed at the separation rotation speed V3 (FIG. 43). 44), the arrangement of the slide member 420 when the meniscus member 460 rotates can be moved to the center side (vertical center side) (see FIG. 40B and FIG. 43B). Thereby, the variation of production can be increased.

  Next, with reference to FIG. 48, the separation rotational speed V3 and the joint rotational speed V4 described above will be described as a graph. FIG. 48 is a graph showing the rotational speed V of the double-layer gear 7451. 48, the horizontal axis represents the position (P) of the slide member 420 between the retracted position (P = 0) and the extended position (P = Pmax), and the vertical axis represents the slide member 420. The rotational speed V of the double-layer gear 7451 rotated during the sliding movement is shown.

  In the horizontal axis of FIG. 48, the first position P1 means a position (see FIG. 39B) where the first projecting gear member 7452e1 is first arranged to face the reversing gear 7453, and the second position P2 is The second projecting gear member 7452e2 is a position where the second projecting gear member 7452e2 is initially arranged to face the reversing gear 7453 (refer to FIG. 42C).

  As described above, in the present embodiment, when the two-layer gear 7452 is rotated at the joint rotation speed V4, the posture of the half moon member 460 starts immediately after the slide member 420 reaches the first position P1. On the other hand, when the double-layer gear 7452 is rotated at the separation rotational speed V3, the posture of the half-moon member 460 starts to change immediately after the slide member 420 reaches the second position P2.

  That is, if two types of slide movement speeds of the slide member 420 are set, the slide member 420 when the posture of the half-moon member 460 starts to change without changing the slide movement speed of the slide member 420 during the movement is set. The position of can be changed. Therefore, variations in the effects of the slide member 420 and the half moon member 460 can be increased.

  Although the present invention has been described based on the above embodiment, the present invention is not limited to the above embodiment, and various modifications can be easily made without departing from the spirit of the present invention. It can be guessed.

  In each of the above-described embodiments, a part or all of the configuration in one embodiment may be combined with or replaced with a part or all of the configuration in the other embodiments to form another embodiment.

  In each of the above embodiments, the case where the claw member 463 of the meniscal member 460 moves due to the movement of the slide rack 442 has been described, but the present invention is not necessarily limited thereto. For example, the locking pin is disposed in a rotational locus in which the driving lever 467 is rotated by the rotation of the meniscal member 460, and the meniscal member 460, the driving lever, and the like are blocked by the locking pin. A mode in which a difference in rotation angle is generated during the movement of the claw member 463 may be employed. In this case, the rotation of the half-moon member 460 and the movement of the claw member 463 can be interlocked.

  In each of the above-described embodiments, the case where the notch 422d of the slide member 420 is formed in an arc shape has been described, but the present invention is not necessarily limited thereto. For example, it may be cut out in a rectangular shape in a direction away from the drive gear 473. As a result, the degree of freedom in designing the notch 422d can be improved and the material required for the slide member 420 can be reduced.

  In each of the above-described embodiments, the case where the shape of the drive gear 473 connected to the tooth tips is substantially circular has been described, but the present invention is not necessarily limited thereto. For example, the drive gear 473 may be divided into four in the circumferential direction, and the gear teeth may be different for each of the divided portions. In this case, by attaching the drive gear 473 with the gear teeth having a short tooth portion directed toward the transmitted leg 422, the size required for the notch 422d of the transmitted leg 422 in order to pass the drive gear 473. The thickness can be reduced. On the other hand, the transmission of the driving force to the transmitted leg 422 can be ensured at the portion where the gear teeth have long teeth. In addition, in the divided | segmented part mentioned above, there may be a part in which a gear tooth is not formed.

  In each of the above-described embodiments, the case where the drive gear 473 is attached / detached through the notch portions 422d formed in the pair of the transmitted leg portions 422 arranged to face each other is not necessarily limited thereto. For example, the notched portion 422d is not formed in the transmitted leg portion 422, and the transmitted leg portion 422 may be formed to be movable in a direction away from each other (a direction perpendicular to the sliding direction). In this case, the drive gear 473 cannot be removed when the pair of transmitted leg portions 422 are arranged close to each other, while the drive gear 473 is removable when the pair of transmitted leg portions 422 are arranged at a distance. can do.

  In the fifth embodiment, the case has been described in which the embedded member 5452h formed of a magnetic material is embedded in the embedded hole 5452g of the two-layer gear 5452. However, the present invention is not necessarily limited thereto. For example, a mode in which the periphery of the starting gear tooth 5452b1 of the two-layer gear 5452 is covered with a magnetic material may be used. Accordingly, since the magnetic material can be disposed outside the starter gear teeth 5542b1, the interval between the reversing gear 5453 and the magnetic material can be reduced, and the engagement between the two-layer gear 5452 and the reversing gear 5453 is started. Magnetic force can be made stronger.

  In the fifth embodiment, the case where the embedding hole 5453f is formed in the starting gear tooth 5453b1 of the reversing gear 5453 has been described, but the present invention is not necessarily limited thereto. For example, the embedding hole 5453f may be formed in the engaging protrusion receiving portion 453d and the embedding member 5453g may be embedded. In this case, the embedding members 5452h and 5453g are buried so that the magnetic force of the embedding member 5453g and the magnetic force of the embedding member 5452h embedded in the two-layer gear 5452 are repelled, thereby reversing the two-layer gear 5452. The impact at the time of contact of the gear 5453 can be reduced. That is, the reversing gear 5453 is rotated away from the starting gear teeth 5452b1 by the repulsive magnetic force before the starting gear teeth 5452b1 of the double-layer gear 5452 are brought into contact with the engaging protrusion receiving portion 453d of the reversing gear 5453. Can do. Accordingly, it is possible to improve the durability of the starter gear teeth 5452b1.

  In the seventh embodiment, the case where the masses of the protruding gear members 7452e are equal to each other has been described. However, the present invention is not necessarily limited thereto. For example, the protruding gear members 7452e may be formed with different masses, and the spring constant of the biasing spring 7452f that biases the protruding gear member 7452e having a larger mass may be formed larger. Thereby, the difference in how the protruding gear member 7452e protrudes due to the size of the mass can be mitigated by the magnitude of the urging force of the urging spring 7452f.

  In the seventh and eighth embodiments, the protruding gear member 7452e of the two-layer gears 7452 and 8452 is formed so as to be movable, so that the timing of contact between the two-layer gears 7452 and 8452 and the reverse gear 7453 can be changed. However, the present invention is not necessarily limited to this. For example, the reversing gear 7453 may be formed so as to be movable in the direction perpendicular to the axis of the double-layer gears 7451 and 8452. In this case, the reversing gear 7453 can be separated from the two-layer gears 7452 and 8452 to form a state in which the reversing gear 7453 is not in contact with each other. It can be. Therefore, even when the movable projecting gear member 7452e is not necessary, the timing of contact between the two-layer gears 7452 and 8452 and the reverse gear 7453 can be changed.

  In the seventh and eighth embodiments, the protruding gear member 7452e of the two-layer gears 7452 and 8452 is formed so as to be movable, so that the timing of contact between the two-layer gears 7452 and 8452 and the reverse gear 7453 can be changed. However, the present invention is not necessarily limited to this. For example, the two-layer gears 7452 and 8452 may be capable of forming a first state in which the reversing gear 7453 and the transmission gear 451 are not engaged and a second state in which the reversing gear 7453 and the transmission gear 451 are engaged. In this case, in the first state, the driving force is not transmitted to the two-layer gears 7452 and 8452, while in the second state, the driving force can be transmitted to the two-layer gears 7452 and 8452. Therefore, even when the movable projecting gear member 7452e is not necessary, the timing at which the reversing gear 7453 starts to operate can be changed.

  In the eighth embodiment, the case where the masses of the protruding gear members 7452e are equal and the spring constants of the biasing springs 8252f are different from each other has been described. However, the present invention is not necessarily limited thereto. For example, the spring constants of the urging springs 8452f may be the same, and the masses of the protruding gear members 7452e may be different. As a result, it is possible to adjust the amount of protrusion of each projecting gear member 7452e more easily than adjusting the spring constant.

  In each of the above embodiments, the case where the drive gear 473 is pivotally supported at one point on the drive shaft of the drive motor 472 has been described, but the present invention is not necessarily limited thereto. For example, a plurality of pins protrude from the end of a shaft support member fixed to the drive shaft of the drive motor 472, and a plurality of fitting portions into which a plurality of pins are fitted to the rotating body portion of the drive gear 473 are formed. In addition, the shaft support member and the drive gear 473 may be engaged at a plurality of points. In this case, since the phase relationship between the drive shaft of the drive motor 472 and the drive gear 473 can be maintained by the pin being hooked on the drive gear 473 in the rotation direction, the fit between the drive gear 473 and the plurality of pins is formed loosely. can do.

  As a result, the force required to separate the drive motor 472 and the rotating body portion of the drive gear 473 can be reduced, so that the front side wall portion 422c of the transmitted leg portion 422 is deformed or excessive stress is applied to the drive motor 472. It can be prevented from being added.

  You may implement this invention in the pachinko machine etc. of a different type from said each embodiment. For example, once a big hit, a pachinko machine that raises the expected value of the big hit until a big hit state occurs (for example, two times or three times) including that (for example, a two-time right item, a three-time right item) May also be implemented. Further, after the jackpot symbol is displayed, it may be implemented as a pachinko machine that generates a special game that gives a player a predetermined game value on the condition that a ball is won in a predetermined area. Further, the present invention may be implemented in a pachinko machine that has a special area such as a V-zone and has a special gaming state as a necessary condition for winning a ball in the special area. Further, in addition to the pachinko machine, the game machine may be implemented as various game machines such as an alepatchi, a sparrow ball, a slot machine, a game machine in which a so-called pachinko machine and a slot machine are integrated.

  In the slot machine, for example, a symbol is changed by operating a control lever in a state where a symbol effective line is determined by inserting coins, and a symbol is stopped and confirmed by operating a stop button. Is. Accordingly, the basic concept of the slot machine is that it is provided with a display device for confirming and displaying the identification information after variably displaying the identification information string composed of a plurality of identification information, and resulting from the operation of the starting operation means (for example, the operation lever) The variation display of the identification information is started, and the variation display of the identification information is stopped and fixedly displayed due to the operation of the operation means for stop (for example, the stop button) or when a predetermined time elapses. It is a slot machine that generates a special game that gives a player a predetermined game value on the condition that the combination of identification information at the time is a specific condition. In this case, the game medium is typically a coin, medal, etc. Take as an example.

  In addition, as a specific example of a gaming machine in which a pachinko machine and a slot machine are fused, a display device is provided that displays a symbol after a symbol string composed of a plurality of symbols is variably displayed, and has a handle for launching a ball. What is not. In this case, after throwing a predetermined amount of spheres based on a predetermined operation (button operation), for example, the change of the symbol is started due to the operation of the operation lever, for example, due to the operation of the stop button, or With the passage of time, the variation of the symbol is stopped, and a special game that gives a predetermined game value to the player is generated on the condition that the determined symbol at the time of stoppage is a so-called jackpot symbol. In this case, a large amount of balls are paid out to the lower tray. If such a gaming machine is used in place of a slot machine, only a ball can be handled as a gaming value in the gaming hall. Therefore, the gaming value seen in the current gaming hall in which pachinko machines and slot machines are mixed is used. Problems such as the burden on equipment due to the separate handling of medals and balls and restrictions on the location of the gaming machine can be solved.

  The concept of various inventions included in the above-described embodiment in addition to the gaming machine of the present invention is shown below.

<An example of a technical idea in which the drive gear 473 and the notch 422d overlap>
A gear tooth is engraved on a side surface supported by a base member and includes a first gear member and a second gear member engaged with each other. At least the first gear member is formed of a rotating gear, and the second gear member Is provided with a plate-like portion covering the side surface of the gear tooth, and the plate-like portion is the gear tooth of the first gear member in the rotation axis direction view of the first gear member, and the second gear tooth. A gaming machine formed so as to be able to overlap with the gear teeth engaged with a gear member, wherein the plate-like portion is passed from a tooth tip side to a tooth bottom side of the gear teeth of the second gear member. The cutout portion is formed, and the cutout portion and the first gear member are disposed at predetermined positions, so that at least the first gear member and the plate-like portion rotate the first gear member. It is possible to form specific phase positions that are visible at intervals when viewed in the axial direction. Gaming machine A1, characterized in that.

  Here, in a gaming machine such as a pachinko machine, a plate-like portion is formed on the side surface of the gear tooth of one of the pair of gear members engaged with each other. There is a gaming machine that prevents the other gear member, which is the gear member on the opposite side of one gear member, from moving in the axial direction (see, for example, Japanese Patent Application Laid-Open No. 2012-217702). However, in the conventional gaming machine described above, when the other gear member is extracted, it is necessary to extract one gear member in advance. For this reason, there is a problem that the maintainability is lowered.

  On the other hand, according to the gaming machine A1, the notch portion is formed in the plate-like portion, so that the plate-like portion and the first gear member are at least at the specific phase position as viewed in the rotation axis direction of the first gear member. Visible at intervals. Therefore, since the first gear member can be pulled out through the notch portion of the plate-like portion at the specific phase position, the first gear member can be exchanged without removing the second gear member in advance. Therefore, the maintainability of the pair of gear members to be engaged can be improved.

  Since the first gear member is formed of a rotating gear, the second gear member on which the plate-like portion is formed may be a rotating gear or a rack gear.

  In the gaming machine A1, the notch portion has a width formed along the direction in which the gear teeth of the second gear member are arranged on the tooth tip side of the second gear member. The distance between the points where the outer shape of the second gear member intersects the tooth tip circle of the first gear member is set equal to or slightly larger than the distance along the gear tooth continuous direction of the second gear member. A gaming machine A2.

  According to the gaming machine A2, in addition to the effects produced by the gaming machine A1, the period in which the first gear member overlaps the notch portion when viewed in the rotation axis direction of the first gear member can be shortened to the minimum. Thereby, the effect | action which controls that a 1st gear member moves to a rotating shaft direction can be ensured by a plate-shaped part.

  The shape of the notch is not particularly limited, and may be an arc shape or a rectangular shape.

  Also, the size of the gear teeth of the second gear member need not be uniform. For example, when the second gear member is divided into four in the circumferential direction, and the size of the gear teeth (particularly the tooth depth) is different for each of the divided portions, the tip circle of the small gear teeth and the second gear Compared to the case where the notch is formed based on the tooth tip circle of a large gear tooth by forming the notch at the distance between the points where the outer shape of the member's tooth tips intersects. It can suppress that a part enlarges. Therefore, the action of restricting the movement of the first gear member in the rotation axis direction can be ensured by the plate-like portion. In addition, in the divided | segmented part mentioned above, there may be a part in which a gear tooth is not formed.

  In the gaming machine A1 or A2, the notch is a circle formed coaxially with the first gear member and formed with a diameter slightly larger than the tooth tip circle of the first gear member. A gaming machine A3, which is formed in an overlapping shape when projected onto the plate-like portion from the rotational axis direction of one gear member.

  According to the gaming machine A3, in addition to the effects produced by the gaming machine A1 or A2, the notch is formed to have a diameter slightly larger than the tooth tip circle of the first gear member, and a circle coaxial with the first gear member is formed. It is formed in an overlapping shape when projected onto the plate-like portion from the rotational axis direction of one gear member. Therefore, it is possible to minimize the size of the notch portion, to ensure the maximum formation area of the plate-like portion, and to improve the rigidity of the plate-like portion.

  Note that the size of the gear teeth of the second gear member need not be uniform. For example, when the second gear member is divided into four in the circumferential direction, and the size of the gear teeth (particularly the tooth depth) is different for each of the divided portions, the tip circle of the small gear teeth and the second gear Compared to the case where the notch is formed based on the tooth tip circle of a large gear tooth by forming the notch at the distance between the points where the outer shape of the member's tooth tips intersects. It can suppress that a part enlarges. Therefore, the formation area of the plate-like portion can be ensured to the maximum, and the rigidity of the plate-like portion can be improved. In addition, in the divided | segmented part mentioned above, there may be a part in which a gear tooth is not formed.

  In the gaming machine A2 or A3, the gear teeth engraved on the first gear member and the gear teeth engraved on the second gear member are in a proper meshing state in which the relationship between meshing gear teeth is fixed In the proper meshing state, the first gear member is moved along the notch formed in the second gear member and meshed with the second gear member. A gaming machine A4 characterized by being formed.

  According to the gaming machine A4, in addition to the effects produced by the gaming machine A2 or A3, the first gear member and the second gear member are moved along the outer shape of the notch of the plate-like portion of the second gear member. When meshing with the gear member, the gear teeth are meshed in a proper meshing state.

  Therefore, in the case where the first gear member and the second gear member are engaged with each other in the proper meshing state, the first gear member and the second gear member are aligned at the notch portion of the plate-like portion. It can be carried out. Thereby, since the meshing adjustment of the first gear member and the second gear member can be facilitated, the maintainability of gear replacement can be improved.

  Note that the case where the relationship between the teeth in which the first gear member and the second gear member mesh with each other is fixed is an incomplete gear in which the rotating gear member to be engaged is engraved with teeth on a part of the side surface. There are cases where there is a case where a movable rack member that reciprocates with respect to the rotating gear member is engaged.

  When changing gears, for example, there is a problem of which tooth of the second gear member is engaged with each tooth of the first gear member. In this case, the proper engagement state is established in relation to the teeth meshing with each other. In order to mesh the teeth, it is only necessary to prevent the gear teeth meshing with each other from shifting by at least one tooth.

  In the gaming machines A1 to A4, the gaming machine A5 is characterized in that a movement resistance of at least one gear member of the first gear member or the second gear member is increased at least in the specific phase position.

  According to the gaming machine A5, in addition to the effects produced by the gaming machines A1 to A4, the movement resistance of at least one of the first gear member and the second gear member increases at least at the specific phase position. For this reason, the maintenance worker can make the operation of engaging the pair of gear members (inserting the gear members at the proper meshing positions) easy, for example, by relying on the increase in movement resistance.

  That is, in a state where the first gear member and the second gear member are stopped in the middle of movement, if the notch portion of the plate-shaped portion does not match the first gear member, the first gear member is removed. Even if it is going to be brazed, the plate-like part is in the way and cannot be removed. Therefore, it is necessary to move the second gear member. In this case, by moving the second gear member to a position where the resistance increases, the notch portion of the plate-like portion can be formed at a position that matches the first gear member, and the first gear member is removed. Becomes easy.

  The movement resistance increases when, for example, a friction member that rubs against at least one of the first gear member and the second gear member at the specific phase position is disposed, or at the specific phase position, Examples include a case where at least one of the second gear members reaches the end of movement.

  In the gaming machines A1 to A4, the first gear member and the second gear member are formed so as to move to the moving end, and the first gear member and the second gear member are arranged at the moving end. In such a case, the gaming machine A6 is characterized in that the plate-like portion and the first gear member at least partially overlap each other when viewed in the rotation axis direction of the first gear member.

  According to the gaming machine A6, in addition to the effect of any of the gaming machines A1 to A4, when the first gear member and the second gear member are arranged at the movement end, the first gear member is viewed in the direction of the rotation axis. The plate-like portion and the first gear member at least partially overlap each other. That is, a specific phase position (a state in which the notch portion matches the first gear member) is formed at a position different from the moving end of the first gear member and the second gear member. Therefore, when the first gear member and the second gear member are moved and the first gear member approaches the specific phase position, the first gear member has a sufficient speed in the rotational direction (axial vertical direction). . Therefore, the wobble of the first gear member that tends to occur at the specific phase position can be mitigated by the momentum in the rotation direction of the first gear member.

  The gaming machines A1 to A6 each include a drive motor that generates a driving force, and the first gear member is pivotally supported by the drive motor in a detachable manner, and a layer between the drive motor and the first gear member. The gaming machine A7 is characterized in that the plate-like part is formed on the machine.

  According to the gaming machine A7, in addition to the effects produced by the gaming machines A1 to A6, the first gear member is pivotally supported by the drive motor in such a manner that it can be pulled out.

  Here, even if the first gear member is engaged with the second gear member from the side where the plate-like portion is formed, the first gear member is brought into contact with the plate-like portion to prevent movement, so that the first gear member is prevented from moving. The gear member and the second gear member cannot be engaged with each other. Therefore, when the first gear member is pivotally supported by the drive motor, there is a possibility that the arrangement position of the drive motor is limited.

  On the other hand, according to the gaming machine A7, since the first gear member can pass through the notch portion of the plate-like portion, the arrangement position of the drive motor is not limited by the relationship with the plate-like portion. The degree of freedom in arranging the motor can be improved.

  In addition, since the plate-like portion of the second gear member is formed in a layer between the drive motor and the first gear member, when replacing the drive motor, the drive motor and the first gear member should be removed together. It is possible to select whether to remove only the drive motor.

  That is, the drive motor and the first gear member can be easily separated by pulling out the drive motor while keeping the first gear member in contact with the plate-like portion. By exchanging the drive motor in this way, the drive motor can be replaced while maintaining the meshed state of the first gear member and the second gear member, and the first gear member and the second gear member can be replaced again. It is possible to eliminate the need for adjusting the meshing. Thereby, maintainability can be improved.

  In addition, as a case where the first gear member is pivotally supported in such a manner that it can be pulled out from the drive motor, the case where the first gear member is fitted and fixed to the drive shaft of the drive motor, or the tip of the drive shaft of the drive motor. A case where a plurality of pins project from the disposed adapter and the plurality of pins are inserted into the first gear member is exemplified.

  In the gaming machine A7, the first gear member includes a shaft portion whose one end portion is fixed to the drive shaft of the drive motor and the other end portion opposite to the one end portion of the shaft portion. A rotating body portion coupled to the end portion, wherein the shaft portion and the rotating body portion are formed so as to be separable, and the shaft portion protrudes in an axial direction from an end surface of the other end portion. Provided with a plurality of projecting pins, the rotating body portion includes a plurality of fitting portions into which the plurality of projecting pins are respectively fitted, and the connection between the shaft portion and the rotating body portion is the plurality of the projecting pins. A gaming machine A8, wherein projecting pins are formed by being fitted into the plurality of fitting portions.

  Here, in order to bring the first gear member into contact with the plate-like portion and pull it out directly from the drive shaft of the drive motor, a force greater than the static friction generated between the drive shaft of the drive motor and the first gear member is required. Thus, a force greater than the static friction is applied to the second gear member through the plate-like portion in contact with the first gear member. The static friction is set to be large in order to maintain the phase relationship between the drive shaft of the drive motor and the first gear member, so that the plate-like portion may be deformed or excessive stress may be applied to the drive motor. .

  On the other hand, according to the gaming machine A8, in addition to the effect produced by the gaming machine A7, a plurality of projecting pins are projected at the end of the shaft portion fixed to the drive shaft of the drive motor, and the rotating body portion is projected. A plurality of fitting portions into which the installation pins are fitted are formed. That is, by engaging the shaft portion and the rotating body portion at a plurality of points, the phase relationship between the drive shaft of the drive motor and the first gear member can be maintained without increasing static friction.

  Therefore, the force required to separate the drive motor and the rotating body portion of the first gear member can be reduced. Therefore, it can prevent that the plate-shaped part of a 2nd gear member deform | transforms, or an excessive stress is added to a drive motor.

  In addition, as a fitting part, the hollow formed in a through-hole or a bottomed cylindrical shape is illustrated.

  In the gaming machine A7 or A8, the game machine is disposed in the vicinity of the drive motor, and extends in a direction opposite to the extending direction of the drive shaft of the drive motor along the side surface of the motor case of the drive motor. A gaming machine A9, comprising a restriction unit.

  According to the gaming machine A9, in addition to the effects produced by the gaming machine A7 or A8, when pulling out the driving motor from the first gear member, while pressing the driving motor against the restricting portion extending along the side surface of the driving motor Can be pulled out. Thereby, it can suppress that the axial center of a drive motor inclines with respect to a 1st gear member, and can suppress that a 1st gear member deform | transforms.

  In the gaming machine A9, the restriction portion is formed in a pair with the motor case of the drive motor interposed therebetween, and the extending end of one restriction portion of the pair of restriction portions is the motor case of the drive motor. The game machine A10 is characterized in that it is formed on the drive shaft side from an end surface opposite to the end surface on which the drive shaft is disposed.

  According to the gaming machine A10, in addition to the effects produced by the gaming machine A9, the extended end of one of the regulating portions formed in a pair is formed closer to the drive shaft than the end surface of the motor case of the drive motor. Therefore, the extended end of one of the restricting portions can be effectively used as a fulcrum for pulling out the drive motor. That is, since the extending end of the restricting portion and the side surface of the drive motor are disposed adjacent to each other, the extending end of the restricting portion is used as a fulcrum and the force is applied to the drive motor using the side surface of the drive motor as an operating point. The distance to the action point can be made the shortest. Thereby, the force required for extraction can be suppressed.

  Further, when pulling out the drive motor using the extended end of one restricting portion as a fulcrum, the drive motor can be pulled out while pressing the drive motor against the restricting portion on the opposite side of the one restricting portion. Thereby, when pulling out the drive motor, the degree of inclination of the drive motor with respect to the other gear can be suppressed.

  In the gaming machine A10, of the pair of restricting portions, the other restricting portion, which is the restricting portion on the opposite side of the one restricting portion, projects in the same manner as the extended end of the one restricting portion, or The gaming machine A11 is characterized in that it is formed so as to protrude from the extending end of the one restricting portion to the opposite side of the drive shaft of the drive motor.

  According to the gaming machine A11, in addition to the effects produced by the gaming machine A11, the other restricting portion to which the drive motor is pressed when the drive motor is pulled out is at least more than the extending end of the one restricting portion. It is formed to project to the opposite side. Therefore, when the drive motor is pulled out with the extended end of one restricting portion as a fulcrum, the action point is closest to the other restricting portion (that is, the action point is a plane perpendicular to the drive shaft of the drive motor In the state of being arranged on a plane including the extended end of one restricting portion), the other restricting portion can prevent the drive motor from moving.

  Thereby, when pulling out the drive motor, it is possible to reliably prevent the drive motor from moving in a direction away from the one restricting portion.

  The gaming machines A7 to A11 include a moving contact member that is disposed opposite to the second gear member with the first gear member interposed therebetween, and the moving contact member of the first gear member is at the specific phase position. The plate-like portion of the second gear member is disposed at a distance from the first gear member in the axial direction view, and overlaps the first gear member in the axial direction view of the first gear member. The gaming machine A12, wherein in at least one of the states, the first gear member and the moving contact member overlap each other when viewed in the axial direction of the first gear member.

  According to the gaming machine A12, in addition to the effects exerted by the gaming machines A7 to A11, the first gear member is simultaneously applied to the plate-like portion of the second gear member and the moving contact member disposed to face the second gear member. Abutted. Thereby, the inclination of the first gear member when the first gear member is pulled out from the drive motor can be suppressed.

<An example of the technical idea that the start gear teeth 452b1 for meshing are formed in a large size>
A main driving gear member formed as a rotating gear, and a driven gear member that starts meshing during rotation of the main driving gear member, and at least one of the main driving gear member and the driven gear member is contacted at the start of the meshing. A game comprising: a meshing tooth to be contacted; and an intermediate tooth meshing when the meshing tooth is engaged after the meshing tooth is engaged, and the meshing tooth is formed larger than the intermediate tooth. Machine B1.

  Here, there is a gaming machine in which the engagement between the main driving gear member and the driven gear member (the side to which the rotation of the main driving gear member is transmitted) is started while the main driving gear member (the side rotated by the drive motor) is rotating. (For example, see JP 2013-244210 A). However, in the conventional gaming machine described above, the teeth that mesh at the start of meshing between the main driving gear member and the driven gear member are subject to collision at the beginning of meshing and are easily damaged. On the other hand, if the gear teeth are made larger, the gear teeth can be prevented from being damaged, but the backlash is increased and it becomes difficult to smoothly rotate the driven gear member. For this reason, it has been difficult to achieve both durability and smooth rotation.

  On the other hand, according to the gaming machine B1, since the meshing teeth are formed larger than the intermediate teeth, at least one of the main driving gear member and the driven gear member has durability of the meshing teeth that meshes at the start of the meshing. The meshing teeth can be prevented from being damaged. Further, since the backlash between the main driving gear member and the driven gear member can be reduced in the intermediate teeth, the rotation of the driven gear member can be smoothly performed when the intermediate teeth are engaged after the meshing teeth are engaged. can do. Thereby, the durability improvement of a meshing tooth and the improvement of the smoothness of rotation of a driven gear member can be made to make compatible.

  Note that the start of meshing means a state in which the meshing teeth formed on at least one of the main gear member and the driven gear member start to come into contact with the other gear member on the opposite side of the one gear member.

  Further, forming the meshing teeth in a large size means that at least one of the tooth width, the tooth thickness, or the toothpick is formed larger than the intermediate teeth.

  The gaming machine B2 includes a holding mechanism that holds the posture of the driven gear member.

  According to the gaming machine B2, in addition to the effects produced by the gaming machine B1, the holding mechanism for holding the attitude of the driven gear member is provided, so that the attitude of the driven gear member in a state where it is not meshed with the main driving gear member can be stabilized. Can do.

  Examples of the holding mechanism include a mechanism that holds the driven gear member in the axial direction and a mechanism that holds the driven gear member by mechanical alignment.

  In the gaming machine B2, the driven gear member includes a cutout portion that is cut out in a direction of retreating from the main drive gear member, and the cutout portion is in contact with the outer periphery of the main drive gear member at at least two points. The holding mechanism is formed by the gaming machine B3.

  According to the gaming machine B3, in addition to the effects produced by the gaming machine B2, a holding mechanism that holds the driven gear member can be formed by abutment of the main driving gear member and the driven gear member at two points. As a result, a separate member for maintaining the posture of the driven gear member can be dispensed with.

  The cutout portion may be any shape as long as it does not interfere with the tooth tip circle of the main gear member, and the shape is not limited. However, at least the radius of curvature of the cutout portion is equal to that of the tooth tip circle of the main gear member. It is formed below the radius.

  In the gaming machine B3, the notch is formed as an arcuate recess that circumscribes the main driving gear member.

  According to the gaming machine B4, in addition to the effect achieved by the gaming machine B3, the notch portion of the driven gear member is brought into contact with the outer periphery of the main driving gear member to improve the effect of maintaining the posture of the driven gear member. Can be made.

  That is, the notch portion of the driven gear member is brought into contact with the outer periphery of the main drive gear member so that the frictional force at the time of contact is prevented from being concentrated on one place, and the frictional force is applied to the entire notch portion. Can be dispersed. Thereby, the location which holds a driven gear member with a main gear member can be increased, and the effect of maintaining the attitude | position of a driven gear member can be improved.

  In addition, the aspect in which a notch part is circumscribed by the main drive gear member is not specifically limited. That is, for example, a form circumscribing the tooth tip circle of the main driving gear member may be employed, or a form in which the gear tooth is omitted from the main driving gear member and circumscribing the omitted surface may be employed.

  In the gaming machine B4, the main driving gear member and the notch portion of the driven gear member have their contact points drawn from the central axis of the main driving gear member to the surface connecting the roots of the driven gear member. A gaming machine B5 formed on at least both sides of a perpendicular.

  According to the gaming machine B5, in addition to the effects achieved by the gaming machine B4, the contact point between the main driving gear member and the notched portion of the driven gear member is on the surface where the root of the driven gear member is connected from the central axis of the main driving gear member. Since it is formed on at least both sides of the drawn perpendicular line, it is possible to prevent the driven gear member from rotating (moving) in both directions when the notch is in contact with the main driving gear member.

  Examples of the driven gear member include a rotating gear member formed as a rotating gear and a rack gear formed as a gear that moves in parallel.

  In any one of the gaming machines B2 to B5, the driven gear member includes an engagement projection receiving portion that is formed larger than the meshing teeth, and the notch portion is formed in the engagement projection receiving portion. The game machine B6 is characterized in that the meshing between the main driving gear member and the driven gear member is started after the meshing teeth of the main driving gear member and the engaging projection receiving portion contact each other. .

  According to the gaming machine B6, in addition to the effects of any of the gaming machines B2 to B5, the engagement protrusion receiving portion is used as a substitute for the teeth that come into contact with the main driving gear member, so that the durability of the driven gear member is increased. Can be improved.

  The engagement protrusion receiving portion in which the notch portion is formed is not originally a portion that engages with the gear teeth of the main driving gear member, but is in contact with the outer peripheral surface of the main driving gear member so that the posture of the driven gear member is This is the part of the role of maintenance. Therefore, the size is not limited according to the size of the gear teeth to be engaged like the gear teeth. Therefore, the durability of the driven gear member is improved by using the engagement protrusion receiving portion formed more robustly than the gear teeth at the portion where the main gear member and the driven gear member are brought into contact with each other at the start of engagement. Can be made.

  In the gaming machine B6, the main gear member includes a hollow portion that is a recess formed adjacent to the meshing tooth, and the meshing tooth of the main gear member is brought into contact with the engagement protrusion receiving portion. The gaming machine B7, wherein the driven gear member is rotated in such a manner that the engaging protrusion receiving part enters the recess part before.

  According to the gaming machine B7, in addition to the effect produced by the gaming machine B6, the driven gear member is rotated before the meshing teeth of the driven gear member abut on the engaging projection receiving portion of the driven gear member. And the driven gear member can be suppressed from impact at the start of meshing.

  Here, when the driven gear member is in contact with the outer peripheral surface of the main driving gear member at two points, even if the main driving gear member rotates, the driven gear member maintains its posture. On the other hand, when the meshing teeth of the main driving gear member come close to the engaging projection receiving portion of the driven gear member, the recess formed adjacent to the meshing teeth faces the engaging projection receiving portion. Since the hollow portion is not in contact with the engagement protrusion receiving portion, the effect of maintaining the posture of the driven gear member is released. Then, the driven gear member is slightly rotated by the frictional force generated between the outer peripheral surface of the main driving gear member and the engaging protruding receiving portion, and the engaging protruding receiving portion enters the recess. As a result, the driven gear member starts to rotate before the meshing teeth of the main driving gear member come into contact with the engaging projection receiving portion of the driven gear member, so that the main driving gear member and the driven gear member start meshing. The impact at the time of doing can be suppressed.

<An example of a technical idea in which the protruding gear member 7452e moves in the radial direction of the two-layer gear 7452>
A driving source for generating a driving force, a main driving gear member rotated by the driving force of the driving source, a first moving member moved in conjunction with the rotation of the main driving gear member, and rotation of the main driving gear member A driven gear member that starts moving in conjunction with the main driving gear member, a second moving member that moves in conjunction with the movement of the driven gear member, and the main driving gear member and the driven gear member. An adjusting device for starting, and the first moving member is moved within a moving range from a moving base end to a moving end, and the driven gear member starts moving in conjunction with the main driving gear member by the adjusting device. A plurality of positions of the first moving member at the time can be formed, the gaming machine C1.

  Here, in a gaming machine such as a pachinko machine, there is a gaming machine that includes a first moving member and a second moving member that are moved by a driving force of a single driving source (see, for example, JP 2009-125092 A). ). However, in the conventional gaming machine described above, there is a problem in that there are few variations in production because the mode of the second moving member at a specific position during the movement of the first moving member is limited to one way.

  On the other hand, according to the gaming machine C1, the adjustment device can form a plurality of positions of the first moving member when the driven gear member starts to move in conjunction with the main driving gear member. A plurality of positions of the first moving member when the moving member starts moving can be formed. Therefore, a plurality of variations of effects of the first moving member and the second moving member can be formed.

  When the driven gear member starts to move in conjunction with the main driving gear member, the driven gear member and the driven gear member may be moved by meshing the main driving gear member and the driven gear member. A mode in which the driven gear member is moved by friction generated between the gear member and the main gear member and the driven gear member are formed of a magnetic material, and a magnetic force generated between the main gear member and the driven gear member. The mode etc. in which a driven gear member is moved are illustrated.

  The adjustment device may be formed in such a manner that at least one gear tooth of the main driving gear member or the driven gear member is formed so as to extend in a direction away from the rotation shaft, or between the shafts of the main driving gear member and the driven gear member. The aspect etc. which are formed so that a distance can be changed are illustrated.

  In the gaming machine C1, the interlocking between the main driving gear member and the driven gear member is based on meshing, and the adjusting device is disposed on the main driving gear member and moves in the radial direction of the main driving gear member. A projecting member that is allowed to protrude from the rotational direction of the main driving gear member to a position where it can abut on the driven gear member; An immersion state disposed at an impossible position can be formed, and the projecting member contacts the driven gear member when the projecting member rotates while the projecting member forms the projecting state. The game machine C2 is configured to start meshing between the main driving gear member and the driven gear member.

  According to the gaming machine C2, in addition to the effects achieved by the gaming machine C1, the manner in which the main driving gear member and the driven gear member are linked differs depending on whether the protruding member of the adjusting device is in an overhanging state or in an immersive state. Can be made.

  Here, the start and release of the engagement between the main driving gear member and the driven gear member can also be performed by changing the inter-axis distance between the main driving gear member and the driven gear member. However, in that case, it is necessary to move the rotating shaft in the direction perpendicular to the axis while maintaining the parallelism of the rotating shaft in order to suppress the meshing resistance between the main driving gear member and the driven gear member. Required. Therefore, the mechanism for moving the main driving gear member and the driven gear member may be complicated.

  On the other hand, in the gaming machine C2, the main driving gear member includes a protruding member formed to be movable in the radial direction, and the main driving gear member and the driven gear when the protruding member protrudes (when the protruding state is formed). Engagement with the member is started. Therefore, it is not necessary to move the rotation shafts of the main driving gear member and the driven gear member, so that the parallelism of the rotation shaft is maintained. Therefore, accuracy is not required for the mechanism for moving the protruding member, and the mechanism for moving the protruding member can be simplified.

  In addition, as a method of forming the protruding member in the extended state, a method in which the protruding member is extended by centrifugal force generated when the main driving gear member is rotated, or a solenoid is disposed inside the protruding member, and the solenoid is driven. Examples include a method of projecting the protruding member. One or more protruding members may be provided.

  In the gaming machine C2, the projecting member receives the urging force generated toward the rotation shaft side of the main driving gear member, thereby forming the immersion state at least in a stationary state of the main driving gear member, and rotating the main driving gear member. The gaming machine C3 is formed so as to be switchable between the immersive state and the overhanging state by switching the rotation speed.

  According to the gaming machine C3, in addition to the effects produced by the gaming machine C2, by changing the rotational speed of the main driving gear member, the protruding state where the protruding member contacts the driven gear member, and the protruding member with respect to the driven gear member Can be switched to the immersive state.

  As a result, the control of the operating speed of the driving source and the state of the protruding member can be linked, so that the interlocking between the main driving gear member and the driven gear member can be made, for example, as compared with the case where the protruding member is extended by a solenoid. Control can be simplified.

  Examples of the member that generates the urging force include elastic springs such as a coil spring and a torsion spring, and members made of a rubber material having sufficient stretchability.

  A plurality of projecting members may be arranged on the main driving gear member with different phases. In this case, by adjusting the weight of each projecting member and the urging force acting on each projecting member, the amount by which each projecting member protrudes can be adjusted.

  In the gaming machine C2 or C3, the projecting member includes a first projecting member and a second projecting member formed out of phase with the first projecting member, the first projecting member and the second projecting member, Are substantially equal in amount overhanging by the rotation of the main gear member, the main gear member includes a first rotation speed at which the first projecting member and the second projecting member form the immersion state, and the first projecting member. The first projecting member and the second projecting member can form a second rotational speed that forms the overhanging state, and the rotational speed of the main driving gear member can be set between the first rotational speed and the second rotational speed. The game machine C4 can be switched during the rotation of the main driving gear member.

  According to the gaming machine C4, in addition to the effect produced by the gaming machine C2 or C3, the phase at which the first protruding member starts to contact the driven gear member by changing the rotational speed of the main driving gear member during rotation, The main drive gear member can be brought into contact with the driven gear member in at least two types of phases, that is, the phase in which the two protruding members start to come into contact with the driven gear member.

  That is, the main gear member is rotated at the first rotation speed, and the rotation speed of the main gear member is changed to the second rotation speed immediately before the first projecting member is positioned on the driven gear member side. Engagement with the driven gear member can be started with one projecting member. On the other hand, the main drive gear member is rotated at the first rotation speed, and the rotation speed of the main drive gear member is changed to the second rotation speed immediately before the second projecting member is positioned on the driven gear member side. Thus, the engagement with the driven gear member can be started by the second projecting member.

  In other words, by arbitrarily selecting the timing at which the rotational speed of the main gear member is increased, the timing for projecting and immersing the protruding member can be arbitrarily selected. That is, even when the movement speed at the start of movement of the first moving member is the same, the timing for moving the second moving member can be changed by the timing for increasing the moving speed of the first moving member. As a result, it is difficult to predict the subsequent effects simply by confirming the speed at the start of the movement of the first moving member, and the attention of the operations of the first moving member and the second moving member can be improved. . Therefore, the effect of the first moving member and the second moving member can be improved.

  In the case where the first projecting member and the second projecting member project with substantially the same projecting amount, the masses of the first projecting member and the second projecting member are made equal and applied to each other. When the forces are equal, or because the mass of the first and second projecting members is different, the radially outward force generated by the rotation of the main driving gear member is different. The case where the urging | biasing force applied to a member is changed is illustrated. For example, when the urging force is generated by an elastic spring, the spring constants of the elastic spring that applies the urging force to the first protruding member and the elastic spring that applies the urging force to the second protruding member are exemplified.

  In the gaming machine C2 or C3, the projecting member is formed with a first projecting member and a phase difference from the first projecting member, and the first projecting member becomes the driven gear member during the rotation of the main driving gear member. A second projecting member that is proximate to the driven gear member after approaching, and the first projecting member and the second projecting member are formed with different projecting amounts projecting by the rotation of the main driving gear member. The main driving gear member includes a separation rotational speed in which the first projecting member of the projecting member forms an immersive state and the second projecting member forms the projecting state, and the first projecting member, A gaming machine C5, wherein both of the second projecting members can form a joint rotation speed at which the projecting state is formed.

  According to the gaming machine C5, in addition to the effect produced by the gaming machine C2 or C3, the state in which the first projecting member abuts the driven gear member without changing the rotational speed of the main driving gear member during rotation, A state in which the protruding member abuts on the driven gear member can be formed.

  That is, the main driving gear member is rotated at a constant speed at the separation rotational speed, so that the main driving gear member is engaged with the driven gear member by the second projecting member. On the other hand, when the main driving gear member is rotated at the common rotation speed, the main driving gear member is engaged with the driven gear member by the first projecting member.

  That is, in order to change the position of the first moving member when the second moving member starts to move, it is not necessary to change the rotational speed of the driving source during the rotation of the main driving gear member. Can be

  One of the gaming machines A1 to A12, B1 to B7, and C1 to C5, wherein the gaming machine is a slot machine. Above all, the basic configuration of the slot machine is “equipped with variable display means for confirming and displaying the identification information after dynamically displaying an identification information string composed of a plurality of identification information, and for operating the starting operation means (for example, an operation lever). As a result, the dynamic display of the identification information is started, and the dynamic display of the identification information is stopped due to the operation of the stop operation means (stop button) or after a predetermined time has elapsed. The game machine is provided with special game state generating means for generating a special game state advantageous to the player on the condition that the confirmed identification information is specific identification information. In this case, examples of the game media include coins and medals.

Above all, the basic configuration of a pachinko gaming machine is provided with an operation handle, and a ball is launched into a predetermined game area according to the operation of the operation handle, and the ball is placed in an operation port disposed at a predetermined position in the game area. As a necessary condition for winning (or passing through the operating port), the identification information dynamically displayed on the display means is determined and stopped after a predetermined time. In addition, when a special gaming state occurs, a variable winning device (specific winning opening) disposed at a predetermined position in the gaming area is opened in a predetermined manner so that a ball can be won, and a value corresponding to the number of winnings is obtained. Examples include those to which values (including data written on magnetic cards as well as premium balls) are given.
