Description

  The present invention relates to a launch operation mechanism of a gaming machine that can be easily assembled.

The launching operation mechanism for the player to perform the operation of launching the ball of the pachinko machine into the game area of the game board is such that when the player rotates the operating body called a handle lever, the operating body electrically controls the operation amount of the operating body. Rotating the volume axis of the variable resistor that converts it into energy. Since the amount of rotation between the operating body and the volume shaft cannot be 1: 1 due to the internal structure of the variable resistor, a drive gear that rotates together with the operating body is provided at the center of the operating body, A driven gear that rotates together with the volume shaft is provided on the shaft, and the drive gear and the driven gear mesh with each other. However, when the drive gear and the driven gear are meshed with each other, if the mutual meshing position is wrong, the rotational movement range of the operating body becomes smaller than the installation range, so the meshing of the drive gear and the driven gear is released. However, once again, the drive gear and the driven gear must be meshed with each other, and there is a drawback that the assembly is troublesome.

The drive gear and the driven gear are moved relative to each other in a direction parallel to the rotation center extending in the front-rear direction of the drive gear and the driven gear, such as moving the driven gear to the front side. The toothed part of the drive gear and the toothed part of the driven gear are meshed with each other, and the rear end of the toothed part of the driving gear is a barrier that prevents the toothed part of the driving gear and the toothed part of the driven gear from engaging with each other. A barrier that prevents the teeth of the drive gear and the teeth of the driven gear from engaging with each other is formed at the front end of the teeth of the driven gear. The barrier of the drive gear and the barrier of the driven gear include the drive gear and A concave tooth portion or a driven gear of the drive gear for determining the mutual meshing position of the drive gear and the driven gear by moving in the front-rear direction parallel to the center of rotation of each driven gear and fitting together. The main feature is that a concave portion connected to the concave tooth portion of the gear and a convex tooth portion of the driving gear or a convex portion connected to the convex tooth portion of the driven gear are formed.

  In the gaming machine launch operation mechanism according to the present invention, the drive gear is provided on the back side of the operating body, the driven gear is provided on the front side of the mechanism housing, and the back side of the operating body and the front side of the mechanism housing face each other. Thus, the drive gear is placed on the front side of the driven gear, the driven gear is placed on the rear side of the drive gear, and in this state, the drive gear and the driven gear are When the drive gear and the driven gear are meshed with each other in the direction parallel to the rotation center extending in both the front and rear directions, the concave or convex portion in the drive gear barrier and the barrier in the driven gear There is an advantage that the convex portions or the concave portions are fitted to each other, and the mutual meshing positions of the driving gear and the driven gear become accurate.

FIG. 6 shows the front of a pachinko machine as a gaming machine to which the launch operation mechanism 1 is attached. In this specification, the directions of “front”, “rear”, “back”, “left”, “right”, “upper”, “lower” are determined from the front side with the gaming machine frame 101 placed in the state of FIG. This is the direction specified when viewed. “Back” and “back” are in the same direction. 1, 3, and 4, the number of teeth of the tooth portion 4; 14 is until the shape of the tooth portion 4; 14 formed with respect to the tooth forming body 5; The number is not limited.

  With reference to FIG. 2, each component of the firing operation mechanism 1 will be described. The firing operation mechanism 1 is called a handle grip, and the drive gear 2 and the driven gear 3 have a characteristic structure. In this characteristic structure, the driving gear 2 is placed on the front side of the driven gear 3, the driven gear 3 is placed on the rear side of the driving vehicle 3, the driving gear 2 is moved rearward, and the driven gear 3 is moved forward. The drive gear 2 and the driven gear 3 are moved relative to each other in a direction parallel to the rotation center extending in the front-rear direction of the drive gear 2 and the driven gear 3 so that the drive gear 2 moves. The tooth portion 4 and the tooth portion 14 of the driven gear 3 are meshed with each other, and at the rear end of the tooth portion 4 of the driving gear 2, the tooth portion 4 of the driving gear 2 and the tooth portion 14 of the driven gear 3 are connected. A barrier 11 for preventing meshing is formed, and a barrier 19 for preventing meshing of the tooth portion 4 of the drive gear 2 and the tooth portion 14 of the driven gear 3 is formed at the front end of the tooth portion 14 of the driven gear 3. 2 and 11 of the driven gear 3 and the driven gear 3. A concave tooth portion of the drive gear 2 for determining the mutual meshing position of the drive gear 2 and the driven gear 3 by being moved closer to each other by moving in the front-rear direction parallel to the respective rotation centers. 4, and a convex portion 20 connected to the convex tooth portion 14 of the driven gear 3.

  As shown in FIG. 1, the drive gear 2 includes a disc-shaped tooth forming body 5 in which the tooth portions 4 are formed, an operation body receiving portion 6 that protrudes forward from the front surface of the tooth forming body 5, Each of the plurality of mounting feet 7 projecting forward from the outer peripheral surface of the body receiving portion 6, the shaft 8 projecting rearward from the back surface of the tooth forming body 5, the recess 10, and the barrier 11 are integrally formed. The outer diameter of the operating body receiving portion 6 and the outer diameter of the shaft 8 are smaller than the outer diameter of the tooth forming body 5. That is, the operating body receiving portion 6 and the shaft 8 are thinner than the tooth forming body 5. The mounting leg 7 sandwiches the rotation center extending in the front-rear direction of the operating body receiving portion 6 and relatively heels in the radial direction of the operating body receiving portion 6. That is, the mounting foot 7 is located on the diameter line of the operation body receiving portion 6. The attachment leg 7 is provided with an attachment hole 9 penetrating in the front-rear direction. Although the tooth portion 4 is continuous in the direction of the outer periphery of the tooth forming body 5, the rotational movement range of the operating body 43 is about 90 degrees, and thus the tooth formation is performed in the same range as the rotational motion range of the operating body 43. An uneven shape is formed on the outer peripheral surface of the body 5. That is, the tooth forming body 5 is a spur gear in which a concave tooth portion 4 and a convex tooth portion 4 are formed on a part of the outer peripheral surface.

  One concave portion 10 is formed at one end portion in the circumferential direction of the tooth portion 4 in the drive gear 2 between the convex tooth portion 4 at the one circumferential end portion and the outer peripheral surface of the tooth forming body 5. . Since the recess 10 has a groove shape that is open in the front-rear direction and the radially outer side parallel to the center of rotation of the drive gear 2, it can also be conceptualized as a concave tooth portion 4. In the tooth forming body 5, a barrier 11 is formed at the rear end of the tooth portion 4 over the entire tooth portion 4 except the recess 10. The outer peripheral surface of the barrier 11 is located in the same plane as the outer peripheral surface of the tooth forming body 5. That is, in the drive gear 2, the curvature radius that is the distance from the rotation center of the tooth forming body 5 to the outer peripheral surface of the tooth forming body 5 and the curvature that is the distance from the rotation center of the tooth forming body 5 to the outer peripheral surface of the barrier 11. The radius and the radius of curvature, which is the distance from the rotation center of the tooth forming body 5 to the crest surface (outer peripheral surface) of the convex tooth portion 4, have the same dimensions. Therefore, the barrier 11 is connected to the rear ends of the convex teeth 4 adjacent to each other, and closes the rear ends of the concave teeth 4. The structure in which the tooth forming body 5 is provided with the recess 10 and the barrier 11 is a characteristic structure of the drive gear 2. The barrier 11 of the drive gear 2 is provided with a concave relief 12. The relief portion 12 moves the drive gear 2 and the driven gear 3 in a direction approaching each other in a direction parallel to the rotation center extending in the front-rear direction of the drive gear 2 and the driven gear 3. 10 and the convex portion 20 of the driven gear 3 are engaged with each other, the one convex tooth portion 14 adjacent to the convex portion 20 of the driven gear 3 and the one convex tooth portion 14 are connected. In order to escape the corner portion 21 of the barrier 19, the groove shape is opened to the front and rear direction parallel to the rotation center of the drive gear 2 and radially outward. The escape portion 12 has such a size that the convex portion 20 of the driven gear 3 cannot enter.

  As shown in FIG. 1, the driven gear 3 includes a disc-shaped tooth forming body 15 in which the tooth portions 14 are formed, a mounting portion 16 protruding forward from the front surface of the tooth forming body 15, and a tooth forming body. 15, the fitting hole 17 provided at the rotation center 15, the stopper 18 provided on the outer peripheral surface of the tooth forming body 15, the barrier 19, and the convex portion 20 are integrally formed. The tooth portion 14 is continuous in the direction of the outer periphery of the tooth forming body 15, but is formed in an uneven shape on the outer peripheral surface of the tooth forming body 15 only in a range where it engages with the tooth portion 4 of the drive gear 2. That is, the tooth forming body 15 is a spur gear in which a concave tooth portion 14 and a convex tooth portion 14 are formed on a part of the outer peripheral surface. The tooth forming body 15 has a barrier 19 between one convex tooth 14 at the other circumferential end of the tooth 14 in the tooth forming body 15 and one concave tooth 14 adjacent thereto. It is formed at the front end of the tooth portion 14 over the other tooth portions 14. The outer peripheral surface of the barrier 19 is located in the same plane as the outer peripheral surface of the convex tooth portion 14. That is, in the driven gear 3, the radius of curvature, which is the distance from the rotation center of the tooth forming body 15 to the outer peripheral surface of the tooth forming body 15, and the valley surface (outer periphery) of the concave tooth portion 14 from the rotation center of the tooth forming body 15. The radius of curvature, which is the distance to the surface), has the same dimensions. A radius of curvature that is the distance from the rotation center of the tooth forming body 15 to the outer peripheral surface of the barrier 19 and a radius of curvature that is the distance from the rotation center of the tooth forming body 15 to the mountain surface (outer peripheral surface) of the convex tooth portion 14. Are the same dimensions. Therefore, the barrier 19 is connected to the front ends of the convex teeth 14 adjacent to each other, and closes the front ends of the concave teeth 14. Thus, the barrier 19 that blocks the front end of the concave tooth portion 14 over the tooth portion 14 other than the one convex tooth portion 14 and the one adjacent concave tooth portion 14 on the tooth forming body 15. In the tooth forming body 15 in which the barrier 19 does not exist, one convex tooth portion 14 at the other circumferential end of the tooth portion 14 forms a convex portion 20 that fits into the concave portion 10 of the drive gear 2. This is a characteristic structure of the driven gear 3.

  Then, the drive gear 2 and the driven gear 3 are arranged such that the drive gear 2 is placed on the front side, the driven gear 3 is placed on the rear side, the drive gear 2 is moved to the rear side, and the driven gear 3 is moved to the front side. When the drive gear 2 and the driven gear 3 are meshed with each other by moving in a direction that is relatively parallel to the rotation center that extends in the front-rear direction, the concave portion 10 of the drive gear 2 and the driven gear 3 are engaged. The drive gear 2 and the driven gear 3 cannot be meshed with each other unless the projections 20 are fitted together. That is, when the drive gear 2 and the driven gear 3 are moved in a direction approaching each other in a direction parallel to the rotation center extending in the longitudinal direction of both, the drive gear 2 and the driven gear 3 are engaged with each other. If the concave portion 10 of the gear 2 and the convex portion 20 of the driven gear 3 are fitted to each other, the driving gear 2 and the driven gear 3 can be engaged with each other as shown in FIG. 2, when the concave portion 10 of the driven gear 3 encounters the barrier 19 of the driven gear 3, or when the convex portion 20 of the driven gear 3 encounters the barrier 11 of the driving gear 2, the driving gear 2 and the driven gear 3 are engaged with each other. I can not match. The attachment portion 16 is provided at the center of the tooth forming body 15. The fitting hole 17 is a deformed hole whose cross section in the direction orthogonal to the rotation center of the driven gear 3 is formed in a half-moon shaped deformed shape and is recessed from the back surface of the driven gear 3 into the mounting portion 16.

When the set screw 79 is fastened to the screw mounting hole 33 of the spring stop portion 29 through the screw insertion hole by the mounting foot 78, the mounting foot 78 is fixed to the spring stop portion 29. By attaching the return spring 75 to the operating body 43 and the mechanism housing 22 in this way, the return spring 75 gives a spring force to the operating body 43 so as to rotate the operating body 43 in the direction of the minimum rotation stop position. When the operating body 43 rotates in the direction of the minimum rotation stop position by the spring force of the return spring 75, at least one of the plurality of escape holes 53 in the operating body 43 is at least one of the outer peripheral surfaces of the plurality of supporting pillars 27.

  With reference to FIG. 6, a pachinko machine exemplified as a gaming machine to which the firing operation mechanism 1 is attached will be described. The gaming machine frame 101 of the pachinko machine is attached to a gaming machine installation facility called an island of a pachinko shop. The gaming machine frame 101 includes a front decorative body 102, a dish device 103, and a firing operation mechanism 1 on the front surface, and a firing mechanism 104 inside. The dish apparatus 103 constitutes a mating member 87 shown in FIG. The game board 105 is housed inside the gaming machine frame 101, so that the inner game area 107 surrounded by the guide rail 106 on the front surface of the game board 105 closes the window 108 of the front decorative body 102 or a synthetic glass. It is covered with a light-transmitting front panel 109 made of resin. The launch mechanism 104 and the input / output line 62 and the wiring 86 shown in FIG. 5 drawn to the back side of the dish device 103 are connected to a control device (not shown) attached to the back side of the gaming machine frame 101 or the back side of the game board 105. Connected. Then, when the control device is activated by power supply, a ball is put in the dish device 103, and the player touches the operation body 43 of the firing operation mechanism 1, the contact detector 60 shown in FIG. A signal as a result of sensing human contact via the metal coating layer is output to the control device. In this state, when the player rotates the operation body 43 from the minimum rotation stop position to the maximum rotation stop position against the spring force of the return spring 75 shown in FIG. 5, for example, to the right, the variable shown in FIG. The resistor 37 outputs a variable resistance value corresponding to the rotational operation amount of the operating body 43 to the control device, and the control device emits a firing output corresponding to the variable resistance value, for example, with a pulse signal having a cycle of less than 100 per minute. Output to the mechanism 104. The launching mechanism 104 thus driven launches the balls supplied from the dish device 103 toward the game area 107 one by one. This launched ball is launched into the space between the front panel 109 and the game area 107 via the launch passage 110 partitioned by the guide rail 106, and the ball launched into this space flows down the space. When a winning component 111 in the game area 107 is won, a winning ball detector (not shown) that detects a winning ball in the winning component 111 outputs a winning detection signal to the control device, and the control device receives a winning ball corresponding to the winning detection signal.

  According to this best mode, in FIG. 2, the drive gear 2 is attached to the back side of the operating body 43, the driven gear 3 is attached to the front side of the mechanism housing 22, and the back side of the operating body 43 and the front side of the mechanism housing 22 When the operator meshes the tooth portion 4 of the drive gear 2 and the tooth portion 14 of the driven gear 3 with each other in the process in which the operating body 43 and the mechanism housing 22 are combined with each other, the drive gear 2 and the driven gear 2 are driven. The gear 3 becomes a darkness hidden by the operating body 43, but the rear end of the tooth portion 4 of the drive gear 2 is closed with the rear end of the concave tooth portion 4 and the tooth portion 4 of the drive gear 2 and the driven gear. 3 is formed, and the barrier 11 of the drive gear 2 is brought close to and fitted to the barrier 11 of the drive gear 2 by moving in the front-rear direction parallel to the rotation centers of the drive gear 2 and the driven gear 3. By driving gear Is formed in the front end of the toothed portion 14 of the driven gear 3 at the front end of the toothed portion 14 of the driven gear 3. A barrier 19 is formed to prevent the engagement between the portion 4 and the tooth portion 14 of the driven gear 3. The barrier 19 of the driven gear 3 is moved in the front-rear direction parallel to the rotation centers of the drive gear 2 and the driven gear 3. Protrusions 20 connected to the convex teeth 14 of the driven gear 3 for determining the mutual meshing positions of the drive gear 2 and the driven gear 3 are formed by close fitting with each other. Therefore, when the drive gear 2 and the driven gear 3 move in a direction approaching each other in a direction parallel to the rotation center extending in the longitudinal direction of both, the drive gear 2 and the driven gear 3 are meshed with each other. If the concave portions 10 and the convex portions 20 do not meet each other, the tooth portion 4 of the drive gear 2 and the tooth portion 14 of the driven gear 3 cannot mesh with each other. There is an advantage that the mutual meshing positions in and are accurate.

  A radius of curvature that is the distance from the rotation center of the tooth forming body 5 to the outer peripheral surface of the tooth forming body 5 in the drive gear 2; and a radius of curvature that is the distance from the rotation center of the tooth forming body 5 to the outer peripheral surface of the barrier 11; The radius of curvature, which is the distance from the rotation center of the tooth forming body 5 to the outer peripheral surface of the tooth forming body 5, has the same dimensions as each other, and the outer peripheral surface of the tooth forming body 15 from the rotation center of the tooth forming body 15 in the driven gear 3. And the radius of curvature, which is the distance from the rotation center of the tooth forming body 15 to the outer peripheral surface of the concave tooth portion 14, have the same dimensions, and the tooth forming body 15 in the driven gear 3. The radius of curvature, which is the distance from the center of rotation to the outer peripheral surface of the barrier 19, and the radius of curvature, which is the distance from the center of rotation of the tooth forming body 15 to the outer peripheral surface of the convex tooth portion 14, have the same dimensions. . Therefore, when the drive gear 2 and the driven gear 3 move in directions that are relatively close to each other in a direction parallel to the rotation center extending in the front-rear direction of both, the drive gear 2 and the driven gear 3 are engaged with each other. The barrier 11 of the gear 2 appropriately passes from the front side to the rear side without interfering with the tooth part 14 of the driven gear 3, and the barrier 19 of the driven gear 3 interferes with the tooth part 4 of the driving gear 2. Without any barrier 19 in the driven gear 3 passing through the barrier 11 of the drive gear 2 and passing through the barrier 11 of the drive gear 2. An advantage is that one convex tooth portion 4 adjacent to the diametrically opposed tooth portion 4 is opposed in the radial direction, and one convex portion 20 of the driven gear 3 and one concave portion 10 of the driving gear 2 are appropriately fitted to each other. is there. Since the concave portion 10 of the drive gear 2 is connected to the tooth portion 4 and the convex portion 20 of the driven gear 3 is connected to the tooth portion 14, when the concave portion 10 and the convex portion 20 are fitted as described above, When the gear 2 rotates in the direction of the minimum rotation stop position that is one direction in the circumferential direction, the tooth portion 4 of the drive gear 2 and the tooth portion 14 of the driven gear 3 mesh with each other, and the driven gear 3 rotates the drive gear 2. The advantage is that it rotates properly.

  When the drive gear 2 is attached to the back side of the operation body 43, the concave portion 10 of the drive gear 2 has a structure that can be seen through the residue hole 49 from the front side of the operation body 43. When covering, the recessed portion 10 of the drive gear 2 can be confirmed from the front side of the operation body 43 through the residue hole 49, and the driven gear 3 and the column 27 in the mechanism housing 22 can be confirmed through the escape hole 53 of the operation body 43. There is an advantage that it becomes easy. In a state where the stopper 18 collides with the receiving portion 41 of the mechanism housing 22 and the volume shaft 38 is stopped at the maximum rotation stop position, the concave portion 10 of the driving gear 2 and the convex portion 20 of the driven gear 3 are fitted together. Since it is a structure, there exists an advantage that the recessed part 10 of the drive gear 2 and the convex part 20 of the driven gear 3 can be easily fitted, without the stop position of the driven gear 3 moving. The mechanism housing 22 is provided with a receiving portion (not shown) where the stopper 18 collides at the minimum rotation stop position of the volume shaft 38. The stopper 18 collides with the receiving portion (not shown) so that the volume shaft 38 is at the minimum rotation stop position. In the state where the driving gear 2 is stopped, one concave portion 10 is formed in the driving gear 2 so that the concave portion 10 of the driving gear 2 and the convex portion 20 of the driven gear 3 are fitted to each other. If the concave tooth portion 14 adjacent to this and the driven gear 3 are formed, the stop position of the driven gear 3 does not move at the minimum rotation stop position, and the concave portion 10 of the drive gear 2 and the driven gear 3 are not moved. There is the same advantage that the convex portion 20 can be easily fitted. In addition, the structure is more complicated than forming one recess 10 and one protrusion 20, but the volume shaft 38 is stopped at the maximum rotation stop position and the volume shaft 38 is stopped at the minimum rotation stop position. The concave portion 10 is formed in the driving gear 2 so that the concave portion 10 of the driving gear 2 and the convex portion 20 of the driven gear 3 are fitted to each other, and the convex portion 20 is formed on the driven gear 3. There is the same advantage that the concave portion 10 of the driving gear 2 and the convex portion 20 of the driven gear 3 can be easily fitted.

  As shown in FIG. 7, the drive gear 2 may be fitted into the operating body 43 without being fixed with a set screw. Specifically, the mounting leg 121 of the drive gear 2 protrudes to the front side of the operating body receiving portion 6. The mounting foot 121 is similar to the mounting foot 7 shown in FIG.

The long hole is located at the intersection with the circumference and has a long length in the direction of the diameter of the pedestal 45. Then, the front end portion of the mounting foot 121 protruding forward from the operating body receiving portion 6 is fitted into the gear mounting hole 122 from the back side of the operating body 43 so that the drive gear 2 rotates together with the operating body 43. The operating body 43 is attached to the operating body 43, and the front surface of the operating body receiving portion 6 of the drive gear 2 contacts the back surface of the operating body 43 around the base 45. Since the shaft 8 of the drive gear 2 is fitted into the bearing portion 25 of the mechanism housing 22, the drive gear 2 does not rattle in the radial direction due to the fitting of the mounting foot 121 into the gear mounting hole 122. Therefore, compared with the case where the drive gear 2 is fixed to the operating body 43 with a set screw, there is an advantage that the fitting between the mounting foot 121 and the gear mounting hole 122 which is a long hole is easy and the structure is simple. .

The concave relief 12 is not provided in the barrier 11 of the drive gear 2 but is provided in the barrier 19 of the driven gear 3. The relief portion 12 moves the drive gear 2 and the driven gear 3 in a direction approaching each other in a direction parallel to the rotation center extending in the front-rear direction of the drive gear 2 and the driven gear 3. When the convex portion 125 and the concave portion 126 of the driven gear 3 are fitted to each other, the one convex tooth portion 4 adjacent to the convex portion 125 of the drive gear 2 and the one convex tooth portion 4 are connected. In order to escape the corner portion 21 of the barrier 11, the groove shape is opened to the front-rear direction and the radially outer side parallel to the rotation center of the driven gear 3.
