Description

  According to the present invention, two parallel action pins are synchronously moved on two trajectories having the same shape in a circular motion or a reciprocating arc motion at the same angular velocity so that an operating member linked thereto is reciprocated linearly. It relates to the motion direction changing mechanism.

  Recently, pachinko machines, which are a type of gaming machine, have gained popularity in which a variable display device is disposed on the surface of the gaming board and a start winning opening and a winning device are disposed below the variable display device. The pachinko machine stops when a predetermined time elapses because information displayed on the display unit of the variable display device fluctuates when a game ball wins the start winning opening. Then, when the information at that time is aligned with predetermined specific information (for example, “777”), it becomes a big hit state that is advantageous to the player, and the winning device is released, under a certain condition at a time. Many prize balls are obtained (for example, refer to Patent Document 1).

In addition, there is a decorative member that is associated with the game, in particular, a movable decorative movable member that is expected to increase the excitement of the game (see, for example, Patent Document 2). ).
Japanese Patent Laying-Open No. 2004-41579 (page 4, FIG. 3) JP-A-7-255937 (page 3-4, FIG. 2, FIG. 3)

  However, in the pachinko machine of Patent Document 2, the decorative movable member is exclusively attached to the tip of a solenoid plunger, and the decorative movable member reciprocates linearly in the front-rear direction as the solenoid is excited or demagnetized. I try to let them. In this way, the decorative movable member has its reciprocating linear motion determined by the advance / retreat operation of the solenoid, and since it always moves at a constant speed, the movement speed cannot be freely changed. There is a problem that it is difficult to move the decorative movable member at a speed suitable for the image.

  Further, since the decorative movable member is attached to the tip of the plunger in a cantilevered manner, for example, if the decorative movable member is relatively large and heavy relative to the plunger, the plunger will rattle during long use. There is also a problem that the advancing / retreating operation becomes unstable and a smooth operation of the decorative movable member cannot be expected.

  Therefore, the present invention has been made in view of the above problems, and it is possible to freely change the speed of the reciprocating linear motion using a mechanism that converts a circular motion or a reciprocating arc motion into a reciprocating linear motion. It is an object of the present invention to provide a motion direction conversion mechanism that can be performed extremely stably and smoothly.

  In order to achieve such an object, the present invention, when converting circular motion to reciprocating linear motion, performs two circular motions at the same angular velocity in synchronism with each other on circular trajectories of the same radius around two parallel central axes. A parallel working pin and an actuating member having a groove width substantially the same as the outer diameter of the working pin and provided with a long groove into which each working pin can be fitted and circularly moved. The operation member is made to reciprocate linearly while being simultaneously pushed by the two action pins by circularly moving the action pins at the same angular velocity.

  Specifically, the present invention relates to two rotating bodies that are arranged so that their central axes are parallel and rotationally move with each other, and an actuating member that is arranged so as to reciprocate linearly in a plane perpendicular to the central axes. And a working pin is provided on each side surface of the two rotating bodies on a circular locus having the same radius around the central axis, and the working pin is provided on the working member. By providing a long groove having the same groove width as that of the outer diameter of each of the working pins and capable of circular motion, the two rotating bodies are rotated at the same angular velocity by a driving means as appropriate. A configuration is adopted in which the member is reciprocated linearly while being simultaneously pushed by the two action pins.

  In addition, when reciprocating arc motion is converted into reciprocating linear motion, the present invention is configured to perform two reciprocating arc motions at the same angular velocity in synchronism with each other on arc trajectories having the same radius around two parallel central axes. A parallel working pin and an actuating member having a groove width substantially equal to the outer diameter of the working pin and provided with a long groove into which each working pin is fitted and capable of reciprocating arc motion. The operating members are reciprocally arc-moved at the same angular velocity in synchronism, so that the operating member is reciprocated linearly while being simultaneously pushed by the two operating pins.

  Specifically, the present invention relates to two rotating bodies that are arranged so that their central axes are parallel and reciprocate in a reciprocating arc, and operations that are arranged so as to reciprocate linearly in a plane perpendicular to the central axes. And a working pin is provided on each side surface of the two rotating bodies on an arc locus having the same radius centered on each central axis, while the working member is provided with the above-mentioned action. By providing a long groove that has approximately the same groove width as the outer diameter of the pin and is capable of reciprocating arc motion in which each working pin is fitted, and appropriately reciprocating arc motion of the two rotating bodies at the same angular velocity by a driving means. The operation member is configured to reciprocate linearly while being simultaneously pushed by the two action pins.

  By the way, if it is broadly understood that the curved motion is converted into a reciprocating linear motion, the present invention includes two parallel action pins that perform curved motion at the same speed on two trajectories having the same shape, and An actuating member having a groove width that is substantially the same as the outer diameter of the working pin and provided with a long groove into which each working pin fits and can move in a curved line, and the two working pins are synchronized by appropriate driving means. A configuration is adopted in which the actuating member is reciprocated linearly while being simultaneously pushed by the two action pins by performing a curved motion at the same speed.

  The movement direction conversion mechanism according to the present invention is configured to cause the two working pins to perform a circular motion or a reciprocating arc motion by appropriately driving means so that the actuating member is reciprocated linearly while being simultaneously pushed by the two working pins. Therefore, by appropriately changing the rotational speed of the driving means, for example, the stepping motor, the speed of the operating member, that is, the decorative movable member that is linked to the operating member and has a relationship with the game can be freely changed. Therefore, the decorative movable member can be easily operated at a speed suitable for the image, and the player's expectation can be sufficiently met.

  The actuating member is reciprocated linearly while being simultaneously pushed by two action pins, that is, supported by two points and reciprocated linearly. Therefore, the linear motion is extremely stable and smooth. There is no such thing. Therefore, the decorative movable member provided integrally with the operating member has an effect that a stable operation can be performed at a predetermined speed. Moreover, for example, the guide portion that guides the actuating member is not subjected to a biased load due to the deviation of the actuating member, and the guide portion is less consumed by friction. In addition, since an extra load is not applied to the driving means such as a stepping motor, the durability of these products themselves can be improved.

It is action | operation explanatory drawing of the movement direction conversion mechanism which concerns on a form.

  The pachinko machine P has an outer frame 1 having a vertically long rectangular frame shape, and a main body frame 3 on which one side is pivotally attached to the outer frame 1 and a game board 2 is installed is detachably mounted. A transparent plate holding frame 4 is attached to the upper front surface of the main body frame 3 and is disposed on the front surface of the game board 2 with one side pivotally attached. The transparent plate holding frame 4 is provided with a window opening 5 in the upper center facing the front of the game board 2, and a glass plate or a synthetic resin plate, which is a set of two transparent plates 5a, is disposed in the window opening 5. The opening 5 is blocked. Further, below the window opening 5, an upper ball tray 6 is mounted for storing game balls supplied as a hit ball to a hit ball launching unit (not shown). A lower ball tray 7 for storing game balls overflowing from the upper ball tray 6 is mounted on the lower front surface of the main body frame 3, and an ashtray 8 is provided on one side thereof. On the other hand, an operation handle 9 for adjusting the hitting force of the hit ball is attached to the other side of the lower ball tray 7.

  An inner guide rail 10a and an outer guide rail 10b are spirally laid on the front surface of the game board 2, and a game portion 2a is formed surrounded by the inner and outer guide rails 10a and 10b. The game unit 2a is equipped with, for example, a variable display device 11 having a display unit 11a that variably displays various types of information at the center thereof, and a game ball wins below the display unit of the variable display device 11 A start winning opening 12 for changing the information of 11a is mounted. Further, when the display on the display unit 11a is aligned with specific information (for example, “7, 7, 7”) below, the door 13a is opened, and a large number of winning balls can be obtained at a time under certain conditions. A large winning device 13 is mounted.

  The variable display device 11 operates on the upper front surface of the mounting plate portion 14 surrounding the display portion 11a as the game progresses, and for example, a decorative movable member for exciting the game in this state in a big hit state 15 is mounted. The decorative movable member 15 has a shape resembling a worm, and reciprocates linearly in the left-right direction when the pachinko machine P in FIG. 1 is viewed from the front as the game progresses.

  More specifically, as shown in FIGS. 3 and 4, a horizontally long case body 16 whose front surface is closed is fixed to the front surface of the mounting plate portion 14, and the decorative movable member 15 is disposed on the front surface of the front plate 16a. The On the other hand, a plate-like operating member 17 that is long in the left-right direction is disposed along the back surface of the front plate 16 a of the case body 16. A pair of leg rods 18 and 18 are provided on the front surface of the operating member 17 as guide portions that project forward at the vertical positions on the left and right sides. Each leg rod 18 protrudes forward through a through hole 19 as a guide portion provided in the front plate 16 a, and the front end of each leg rod 18 is fixed to the back surface of the decorative movable member 15. As a result, the decorative movable member 15 reciprocates linearly along the front surface of the front plate 16a together with the actuating member 17.

  Further, spur gears 20a, 20b, and 20c, which are three rotating bodies that are located in the case body 16 and are substantially parallel to the back side of the actuating member 17 and can rotate by meshing with each other, are juxtaposed in the left-right direction. The The spur gears 20a, 20b, and 20c have the same number of teeth and the same pitch circle diameter. In this case, the spur gears 20b and 20c on the center and one side (right side) as viewed from the front of FIG. The spur gear 20a on the other side (left side) is mounted on the back side of the mounting plate portion 14 as viewed from the front. It is attached to a drive shaft 23 of a stepping motor 22 as means. The stepping motor 22 is held by a fixing member 24 provided on the back surface of the mounting plate portion 14, and the drive shaft 23 protrudes to the front side of the mounting plate portion 14 through a through hole 25 provided in the mounting plate portion 14. .

  Therefore, by driving the stepping motor 22, the spur gear 20a on the other side directly connected to the drive shaft 23 of the stepping motor 22 rotates in the clockwise direction as shown by the arrow in FIG. The gear 20b rotates counterclockwise. Further, the spur gear 20c on one side rotates in the clockwise direction. Therefore, although the spur gears 20b and 20c located at the center and one side rotate at the same angular velocity, the rotation directions are different.

  Then, action pins 26b and 26c projecting forward are provided at predetermined positions on one side of the spur gears 20b and 20c located on one side with the center, that is, on the front side. These action pins 26b and 26c are projected from the respective support shafts 21 which are central axes while maintaining the same distance. In other words, the action pins 26b and 26c are circularly moved at the same angular velocity in synchronization with the rotational movement of the spur gears 20b and 20c on a circular locus having the same radius around the support shaft 21. . Further, the action pins 26b and 26c are fitted into long grooves 27b and 27c opened correspondingly to the operation member 17, respectively, whereby the spur gears 20b and 20c and the operation member 17 are linked. Each of the long grooves 27b and 27c is linear and has the same length, and is provided in parallel along a direction orthogonal to the linear motion direction of the actuating member 17 to the left and right sides.

  If the spur gears 20b and 20c rotate in the opposite directions with the action pins 26b and 26c fitted in the long grooves 27b and 27c, the action pins 26b and 26c are always in the opposite directions at the same angular velocity. And move in the long grooves 27b and 27c in opposite directions. Accordingly, the actuating member 17 reciprocates linearly while being simultaneously pushed by the two action pins 26b and 26c.

  The movement direction conversion mechanism according to the first embodiment is configured as described above, and when the stepping motor 22 is stopped, the decorative movable member 15 is stopped as shown in FIGS. 2 (a) and 5 (a). The action pins 26b and 26c are located approximately at the center of the long grooves 27b and 27c, respectively. In this state, for example, when the stepping motor 22 is driven to increase the fun of the game during the game, the action pins 26b and 26c of the central spur gear 20b and the spur gear 20c on one side are circularly moved in opposite directions, As shown in FIG. 5 (b), the long grooves 27b, 27c shown in FIG. 5 (a) proceed in the opposite directions as shown in FIG. Accordingly, the actuating member 17 linearly moves to the left while being simultaneously pushed by the two action pins 26b and 26c.

  Further, as the spur gears 20b and 20c rotate, the action pins 26b and 26c are again positioned at the center of the long grooves 27b and 27c as shown in FIG. 5C, and further shown in FIG. In this way, the long grooves 27b and 27c travel in opposite directions. In this way, the actuating member 17 is reciprocated linearly in the left-right direction by being simultaneously pushed by the action pins 26b, 26c. While the stepping motor 22 is driven and the spur gear 20a on the other side is rotating, the decorative movable member 15 repeats the reciprocating linear motion at a constant speed in the left and right directions as shown in FIG.

  Next, the motion direction conversion mechanism according to the second embodiment will be described. In addition, the detailed description is abbreviate | omitted by attaching | subjecting the same number to the site | part same as the site | part demonstrated in 1st embodiment. 6 is a front view of a main part of a game board to which the motion direction conversion mechanism according to the second embodiment is applied, FIG. 7 is an enlarged front sectional view of the same part, and FIG. 8 is an enlarged sectional view taken along the line ZZ in FIG. FIGS. 9A to 9D are operation explanatory views of the motion direction conversion mechanism according to the second embodiment.

  The variable display device 11 to which the motion direction conversion mechanism according to the second embodiment is applied is provided with a decorative movable member 30 on one side of the mounting plate portion 14, as shown in FIG. Has been. The decorative movable member 30 has a shape resembling a heel, faces upward, has a head portion 30a and a tail portion 30e fixed thereto, and three trunk portions 30b to 30d therebetween are axially attached at the center in the vertical direction. ing. The body portions 30 b to 30 d can swing left and right along the front surface of the mounting plate portion 14 on the front side of the mounting plate portion 14. In order to be interlocked with an operation member 37 described later, a pair of engagement rods 31, 31 projecting rearward are provided on the back surface of the body portion 30c at the intermediate position.

  On the other hand, a vertically long second case body 32b is provided on the front surface of the mounting plate portion 14 so as to face the decorative movable member 30 and the front surface is closed, and further, a first case body 32a of the same size is provided on the front side. Provided integrally. In the first case body 32a, guide members 35, 35 are fixed to the front upper and lower positions of the front plate 33b of the second case body 32b by screws 36. The upper and lower guide members 35, 35 have guide grooves 34, 34 as horizontal guide portions facing inward from each other. An operation member 37 is disposed between the guide members 35 and 35. The operating member 37 is also a vertically long flat plate and is formed in a rectangular shape, and upper and lower end portions 37a and 37a intervene in the upper and lower guide grooves 34 and 34, respectively. Further, the upper and lower end portions 37a, 37a of the actuating member 37 are provided with protrusions 38, 38 having the same height at both end portions thereof. This is to reduce the contact resistance between the both end surfaces of the upper and lower end portions 37a, 37a of the operating member 37 and the inner bottom surfaces of the guide grooves 34, 34, and to make the operation of the operating member 37 smooth.

  Horizontal long holes 39, 39, 39 as horizontal guide portions are formed in the upper end portion, the intermediate portion, and the lower end portion of the operating member 37, respectively, between the upper elongated portion 39, the horizontal elongated holes 39, 39, and in the intermediate portion and the lower end. Straight long grooves 40a and 40b are formed in the center between the horizontally long holes 39 and 39 in a vertical line. The long grooves 40a and 40b are set to have the groove widths substantially the same as the outer diameters of the working pins 51a and 51b described later, and the working pins 51a and 51b are fitted into the long grooves 40a and 40b. Thereby, spur gears 45a and 45b, which will be described later, and the operating member 37 are linked. The long grooves 40a and 40b are orthogonal to the linear motion direction of the actuating member 37 along the upper and lower guide members 35 and 35. Although the two long grooves 40a and 40b are separately provided, if they are not provided with the horizontally long hole 39 in the middle portion, they may be one continuous. A pair of engagement holes 41, 41 are provided between the horizontally long hole 39 at the upper end and the horizontally long hole 39 at the middle part, and the engagement holes 41 protrude from the decorative movable member 30 to the back side. Each engagement rod 31 is loosely fitted. These engagement rods 31, 31 protrude rearward through insertion holes 42, 42 formed in the front plate 33a of the first case body 32a. Thereby, the operation member 37 and the decorative movable member 30 are interlocked.

  Three bosses 43, 43, 43 project forward from the upper and lower guide members 35, 35 on the front surface of the front plate 33 b of the second case body 32 b. The bosses 43 are juxtaposed in a straight line along the center vertical direction. Then, each boss 43 is inserted into each laterally long hole 39 opened to face the operating member 37. Further, a retaining plate 44 having a width wider than the groove width of each laterally long hole 39 is attached to the front end portion of each boss 43 by screwing a screw 36. As a result, the operating member 37 does not fall off and moves linearly in the horizontal direction while being supported by the upper and lower guide members 35, 35 and the bosses 43.

  In the second case body 32b, three spur gears 45a, 45b, 45c, which are rotating bodies, are arranged in a straight line in the vertical direction. Of these, the upper two spur gears 45a and 45b are attached to a support shaft 46 projecting forward from the front surface of the mounting plate portion 14, and the lower spur gear 45c is a drive shaft of a stepping motor 47 as a drive source. 48 is attached to the shaft. The stepping motor 47 is held by a fixing member 49 provided on the back surface of the mounting plate portion 14 in the same manner as described above, and the drive shaft 48 is disposed on the front side of the mounting plate portion 14 through a through hole 50 formed in the mounting plate portion 14. Is projected to.

  On the front surface of the upper two spur gears 45a and 45b, action pins 51a and 51b projecting forward from the respective support shafts 46 and 46, which are central axes, are provided. That is, in this case as well, the action pins 51a and 51b are circularly moved at the same angular velocity in synchronization with the rotational movement of the spur gears 45a and 45b on a circular locus having the same radius around the support shaft 46. Become. Further, circular holes 52, 52 centered on the respective support shafts 46 are formed in the front plate 33b of the second case body 32b so as to face the front surfaces of the two spur gears 45a, 45b from which the action pins 51a, 51b are projected. The working pins 51 a and 51 b are projected forward through the circular holes 52. Then, the action pins 51 a and 51 b are fitted into the long grooves 40 a and 40 b of the operation member 37. Thereby, both the spur gears 45a and 45b and the operation member 37 interlock | cooperate.

  When the spur gears 45a and 45b rotate in the opposite directions with the action pins 51a and 51b fitted in the long grooves 40a and 40b, the action pins 51a and 51b are always synchronized and opposite to each other at the same angular velocity. And move in the long grooves 40a and 40b in opposite directions. Accordingly, the operating member 37 reciprocates linearly while being simultaneously pushed by the two action pins 51a and 51b.

  The motion direction conversion mechanism according to the second embodiment has the above configuration, and the operation thereof will be described next. When the stepping motor 47 is stopped, the decorative movable member 30 is stopped as shown by solid lines in FIGS. 6 and 9 (a), and the action pins 51a and 51b are located at the lower and upper ends of the long grooves 40a and 40b. They are close to each other. In this state, for example, when the stepping motor 47 is driven to increase the fun of the game during the game, the upper and central spur gears 45a and 45b rotate in opposite directions as indicated by arrows in FIG. At the same time, the action pins 51a and 51b are circularly moved in directions opposite to each other and are positioned at substantially the center of the long grooves 40a and 40b. Along with this, the action pins 51a and 51b simultaneously push the inner surfaces of the long grooves 40a and 40b to cause the actuating member 37 to linearly move in the direction of the arrow in FIG.

  Furthermore, after the actuating member 37 reaches the position indicated by the solid line in FIG. 9 (b) along with the rotational movement of the spur gears 45a and 45b, it linearly moves in the opposite direction, which is the direction of the arrow as described above. Furthermore, the actuating member 37 reaches the solid line position in FIG. 9D through the solid line position in FIG. 9 and thereafter moves linearly in the opposite direction as shown in FIG. Return to the solid line position of b). In this way, the above operation is repeated, and the decorative movable member 30 imitating a bag as shown in FIG. 6 moves its trunk portions 30b, 30c, and 30d between the solid line position and the imaginary line position, and the entertainment of the game. To increase.

  In the movement direction conversion mechanism according to the first and second embodiments, the action members 17 and 37 are moved into two action pins by causing the action pins 26b and 26c or the action pins 51a and 51b to move circularly by the stepping motors 22 and 47, respectively. 26b, 26c or action pins 51a, 51b are simultaneously pushed and reciprocated linearly, so that the operating members 17, 37, that is, the decorative movable members 15, 30 are changed by changing the rotational speed of the stepping motors 22, 47. You can change the speed freely.

  The actuating members 17 and 37 reciprocate linearly while being pushed simultaneously by the two working pins 26b and 26c or the working pins 51a and 51b. That is, since it is supported at two points and reciprocates linearly, the linear motion is extremely stable and smooth and does not rattle. In addition, the load is not applied to the id portion due to the offset, and the wear due to the friction of the guide portion is small. Therefore, even if the decorative movable members 15 and 30 are integrally provided on the operating members 17 and 37, the decorative movable members 15 and 30 can perform a stable operation at a predetermined speed. Originally, if the operating members 17 and 37 are pushed simultaneously by the two operating pins 26b and 26c or the operating pins 51a and 51b, the operating pins 26b and 26c or the operating pins 51a and 51b of the operating members 17 and 37 are used. The object of the present invention can be achieved without any significant problem. However, like the operation members 17 and 37 according to the first and second embodiments, the two operation pins 26b and 26c or the operation pins 51a and 51b are separated from each other along the direction orthogonal to the linear motion direction. If the actuating members 17 and 37 are pushed in this state, the actuating members 17 and 37 can be pushed in a balanced manner and operate more stably.

  In the movement direction changing mechanism according to the first and second embodiments, the spur gear has been described as the rotating body, but is not limited to this, and is a gear or pulley such as a helical gear. It is sufficient if the support shafts are rotating bodies parallel to each other. In addition, the number of rotating bodies interposed between rotating bodies provided with projecting pins is not limited to the case where there is no such as in the present embodiment, but one, two, three, four, and five. Or more than that. The long groove includes both those that have penetrated and those that have not penetrated. Further, although not shown in the drawings, a crank portion may be provided on each central axis without using a rotating body, and the action pin may be provided on the tip thereof. Furthermore, each rotating body including the central shafts and the working pins including the first and second embodiments may be rotated by a stepping motor that is a separate driving source.

  In the movement direction conversion mechanism according to the first and second embodiments, the case where the working member is reciprocated linearly by circularly moving the working pin has been described. The operating member may be reciprocated linearly by moving it. In this case, the long groove of the actuating member into which the action pin is inserted is provided along a direction orthogonal to the linear motion direction of the actuating member, but other than this, for example, a circle curved in a convex or concave shape in the linear motion direction You may make it provide in arc shape. In addition, although the example in which any of the motion direction conversion mechanisms is applied to the decorative movable member mounted on the front surface of the variable display device on the game board surface, it is applied to the decorative movable member mounted on the main body frame or the transparent plate holding frame. Of course, it may be.
