Description

  The present invention relates to a drum-type display device for a gaming machine, and in particular, rotates a plurality of drum bodies arranged side by side while having a central axis coaxially and stops them at predetermined angular positions and applies them to the outer peripheral surface thereof. The present invention relates to a drum-type display device for a gaming machine that displays a given symbol.

  A plurality of drum bodies provided with a plurality of symbols in order along the outer peripheral surface of the cylinder are juxtaposed so that their rotation center axes are coaxial, and these are rotated all at once. After that, the drum body is individually stopped after the player's operation or a predetermined time elapses, and the combination of symbols is displayed in a predetermined direction. Such a drum-type display device of a gaming machine notifies a player of “winning” or “out of game” in a game by a combination of displayed symbols.

  Generally, the drum type display device is provided with a driving unit including a motor for each drum body so that the drum body can be rotated and stopped independently. In addition, a stepping motor is used for the rotation, or various gear mechanisms are incorporated so that a plurality of drum bodies can be rotated synchronously.

  For example, Patent Document 1 discloses a drum type display device for a slot machine in which a driving force by a motor is transmitted to a rotating drum body by a magnetic force instead of a gear mechanism. Specifically, a roller member having an annular magnet body on the outer peripheral surface and a rotating drum body provided with a magnet sheet on the outer peripheral surface are arranged close to each other with their outer peripheral surfaces facing each other. The magnet sheet is provided with magnetic poles so as to reverse the magnetism of the N pole and the S pole for every predetermined length in the circumferential direction. The annular magnet body is provided with a small permanent magnet having alternating magnetic poles arranged in an annular shape so that the N pole and S pole magnetism is inverted every predetermined length in the circumferential direction. When the roller member is rotated by a motor, the magnetic field continuously changes around the annular magnet body. This changing magnetic field causes an attractive force and a repulsive force to act on each magnetic pole of the magnet sheet, and the rotating drum rotates while repeatedly approaching and separating the magnetic poles of the magnet sheet and the annular magnet. It is also said that the transmission of the driving force by the motor to the rotating drum body is not a gear mechanism but a magnetic force, so that a troublesome process of disassembling and assembling the gear mechanism when replacing the rotating drum is unnecessary, and the workability is excellent. .

  By the way, in the vicinity of a center display device in which a drum type display device is generally incorporated, for example, a movable accessory is widely installed. It is also required to be compact. On the other hand, a drum-type display device having a compact size so that a driving unit including a motor provided for each rotating drum can be driven by one motor has been developed.

  For example, Patent Document 2 discloses a compact drum-type display device that rotationally drives a plurality of rotating drums with a single motor. Specifically, the display device includes a rotating shaft that rotates using a motor as a power source, and a plurality of rotating drums that are loosely fitted to the torque and transmit torque by frictional force. Torque is transmitted to each rotating drum by frictional force with the rotating shaft, and a plurality of drums can be rotated by one motor. On the other hand, when the rotating drums are stopped, the pawl-shaped stoppers for stopping the drums are moved and meshed with the ratchet gears fixed to the rotating drums, thereby engaging the frictional force between the rotating shaft body and the rotating drums. The rotation of the rotating drum can be stopped individually.

Torque is transmitted and a plurality of drum bodies can be rotated synchronously. Further, even if the rotation of the drum body is stopped against the magnetic force, the rotation of other drum bodies is not affected. That is, a plurality of drum bodies can be synchronously rotated by one motor and each drum body can be stopped individually.

  In the above-described invention, a plurality of the magnets and / or the magnet attracting bodies may be provided for each position obtained by equally dividing the same circumference into a predetermined number. According to this invention, one of the plurality of magnets and one of the plurality of magnet attractors are selectively associated with each other at the start of rotation, that is, each of the magnet attractors is retained while being obtained. The drum body rotates. Therefore, a plurality of drum bodies are rotated synchronously.

  In the above-described invention, the magnet attracting body may also be made of a magnet. According to this invention, the rotation of the shaft body can be more strongly applied to the drum body via the disk body, and for example, the drum body can be stably rotated even when the drum body is rotated at a high speed.

It is a disassembled perspective view of the principal part of the drum type display apparatus by this invention. It is the (a) side view and (b) front sectional view of the principal part of the drum type display device by the present invention. It is a flowchart which shows operation | movement of a drum type display apparatus. It is a sectional side view of the principal part of a drum type display.

  A drum type display device according to one embodiment of the present invention will be described with reference to FIGS.

  As shown in FIGS. 1 and 2, the display device 1 includes a motor 2, a shaft 3 rotated by the motor 2, three disks 10 fixed to the shaft 3, and a disk 10. 3 drums 20 arranged side by side and three stop devices 30 arranged behind each drum 20 as main components.

  The motor 2 is connected to a shaft 3 supported by a bearing or the like (not shown) through a speed reducer and the like, and can give the shaft 3 rotation about the rotation axis R. The motor 2 is connected to a motor drive board (not shown) so as to be supplied with drive power, and is driven based on a signal such as a motor start signal transmitted from a control device (not shown) toward the motor drive board. The motor 2 is controlled to be capable of driving in both forward and reverse directions by a motor drive board.

  A total of three substantially disc-shaped disks 10 are fixed to the shaft 3 at predetermined intervals so that their main surfaces face each other. The disk 10 can be rotated about the rotation axis R by the rotation of the shaft 3. That is, the respective disks 10 move together as the shaft 3 rotates. As shown in FIGS. 3 and 4, the disk 10 has three magnets attracting the same number as the number of symbols to be described later on a circle C <b> 1 centering on the rotation axis R on the main surface on the drum 20 side forming the pair. The members 11 are arranged and planted at equal intervals. Further, the magnet attracting member 11 is arranged so that the rotation angles are aligned between the magnet attracting members 11 arranged on the other discs 10 when the three discs 10 co-operate. In other words, each disk 10 is fixed to the shaft 3 with the magnet attracting members 11 arranged evenly aligned. As the magnet attracting member 11, a screw made of a ferromagnetic material such as iron can be used.

  Each drum 20 has a substantially cylindrical drum end 21 on each disk 10 side, and a substantially cylindrical drum main part 22 extending from the drum end 21 to the opposite side of the disk 10 so that the outer peripheral surface thereof is continuous. Have The drum end portion 21 has a through hole 8 at the center thereof, and is rotatably supported by a shaft 3 inserted through the through hole 8. Thereby, the rotational torque is hardly transmitted from the shaft 3 to the drum 20. The drum main portion 22 is hollow and has a backlight (not shown) therein. Since the drum main part 22 is hollow, it can transmit the light inside. Thereby, for example, the entire front side of the drum main portion 22, that is, the entire symbol displayed on the front side can be displayed brightly.

  On the end face of each drum end 21 on the disk 10 side, three groove portions 23 having the same number as the number of symbols to be described later are provided at equal intervals. Each of the groove portions 23 has a predetermined positional relationship with a pattern to be described later given to the outer peripheral surface of the drum main portion 22, and extends from the outer peripheral surface of the drum end portion 21 toward the rotation axis R to a length that is approximately half of the radius. ing. Further, a substantially cylindrical magnet 24 is further implanted on the end surface of each drum end 21 on the disk 10 side. The magnet 24 faces the circle C1 where the magnet attracting member 11 implanted in the disk 10 is arranged, and is arranged at one place on the circle C2 having the same diameter as the circle C1, and the disk 10 is rotated. Sometimes, one of the magnet attracting members 11 is attracted to each other by magnetic force, and the drum 20 can be rotated following the rotation of the disk 10. In particular, referring to FIG. 3, the magnet 24 is disposed at a position where the rotation angle is substantially opposite to the rotation axis R with the groove 23 positioned near the upper end of the “7” symbol, which will be described later. Thus, the magnet 24 is arranged at a predetermined position having a predetermined positional relationship with a predetermined symbol arranged on each drum 20.

  On the outer peripheral surface of the drum main portion 22, a symbol sheet on which three symbols of “3” and “7” Arabic numerals and a symbol indicating “star” are printed is the groove portion 23 and the predetermined position described above. Given to be in a relationship. In other words, the symbols are positioned so that the vicinity of the upper end of each groove 23 opened on the outer peripheral surface of the drum end portion 21 is close to each other, and are equally disposed on the outer peripheral surface of the drum main portion 22. Due to this positional relationship, when a stopper 34 (described later) is inserted into the groove 23, the symbol immediately below the symbol adjacent to the groove 23 is positioned in front of the display device 1.

  Referring to FIGS. 1 and 2 again, each stop device 30 is arranged behind each drum 20 forming a set, and a stop device main body 31 erected facing the outer peripheral surface of the drum main portion 22. A stopper shaft 32 protruding from the lower side of the stop device body 31, a rod-shaped stopper support 33 connected to the stopper shaft 32 and extending upward, and substantially horizontally from the upper end of the stopper support 33. A stopper 34 extending forward is included.

  The stop device main body 31 has a solenoid (actuator) (not shown) for rotating the stopper shaft body 32 therein. Such a solenoid is connected to the control device via a stopper operation board (not shown), and can be operated by electric power supplied from the stopper operation substrate based on a stopper intrusion signal output from the control device. The solenoid includes a return spring, and can return to the origin based on a stopper removal signal output from the control device. The stopper support 33 and the stopper 34 are located behind the drum end 21. The stop device 30 can cause the stopper 34 to enter the groove portion 23 of the drum end 21 by the rotation of the stopper shaft 32 by the solenoid, and can be removed. The stopper 34 has a curved surface that protrudes toward the distal end so that the stopper 34 can smoothly enter the groove 23 that moves as the drum 20 rotates. Further, the shape of the curved surface is substantially symmetric with respect to the rotation direction of the drum 20, and can smoothly enter the groove portion 23 even when the drum 20 rotates in the reverse direction.

  Next, the operation of the display device 1 will be described in detail with reference to FIG. 5, with reference to FIG. 1, FIG. 2, and FIG.

  Referring to FIGS. 1 and 2 together with FIG. 5, in the motor start step S1, the motor 2 is driven based on a motor start signal transmitted from the control device in response to a winning of a game ball at a specific winning opening. . As a result, the shaft 3 rotates by itself and the three disks 10 fixed to the shaft 3 are rotated at the same rotation angle. Here, the magnet 24 at each drum end portion 21 is attracted to each other by the magnetic force of the magnet attracting member 11 that is first opposed to each other. At this time, as shown in FIG. 6A, the stopper 34 does not enter the groove 23 and is relatively rotatable. For this reason, the magnet 24 is caused to follow the movement of the magnet attraction member 11 while maintaining this attraction relationship, and each drum 20 is transmitted with the rotational torque to each disk 10 and rotates following the rotation. As described above, since each disk 10 is fixed to the shaft 3 and co-operates, each drum 20 rotates in synchronization with the disk 10. Depending on the positional relationship between the magnet attracting member 11 and the magnet 24, there may be a time lag between the start of rotation of the disk 10 at the start and the acquisition of the attracting relationship described above. In the present embodiment, since the three magnet attracting members 11 are evenly arranged on the circumference of the circle C1, the maximum value of the time lag can be reduced, thereby making it possible to start each drum 20 smoothly.

  As described above, each disk 10 is fixed to the shaft 3 so that the magnet attracting member 11 is aligned. Moreover, the magnet 24 is arrange | positioned in the defined position which has predetermined | prescribed positional relationship with the symbol arrange | positioned at each drum 20. FIG. That is, while the drum 20 is rotating, the magnet 24 attracts one of the three magnet attracting members 11 and maintains a positional relationship opposite to each other, so that the magnet attracting member 11 has a predetermined positional relationship with one of the symbols. Will keep. Since the number of symbols and the number of magnet attracting members 11 are the same, and each is arranged at an equal angle in the rotation direction, the three drums 20 maintain their relative angles with each other, that is, adjacent drums. The upper 20 and the lower end of the symbols on 20 are aligned with each other, and the rotation cycle is synchronized. For example, as shown in FIG. 1, the combination of “7”, “3”, and “star” is rotated while being aligned. Thereby, it can show to a player intelligibly that the rotation cycle of the three drums 20 is synchronizing. Further, since the magnet attracting member 11 maintains a predetermined positional relationship with the groove portion 23 in the same manner as the design, the start timing of each drum 20 can be synchronized.

  In the stopper entry step S2, a stopper entry signal is transmitted at a predetermined timing from a control device (not shown). Based on this, power is supplied from the stopper operation board and the solenoid operates to rotate the stopper shaft body 32 and move the stopper 34 toward the drum end 21. By this movement, the stopper 34 once abuts on the outer peripheral surface of the drum end 21 and then slides on the outer peripheral surface, and then enters the groove 23 that has reached first as shown in FIG. 6B. By this intrusion, the stopper 34 and the groove 23 are engaged, and the rotation of the drum 20 is stopped. Then, the attracting relationship between the magnet 24 and the magnet attracting member 11 is cut off. Even if this attraction is cut off, that is, even if one of the three drums 20 is stopped against the magnetic force, the rotation of the disk 10 continues and the rotation of the other drums 20 is not affected. That is, the rotation of the drum 20 can be stopped individually while maintaining the rotation of the disk 10.

  As described above, the groove portion 23 has a positional relationship with respect to the symbol such that one of the symbols is positioned in front when the stopper 34 is inserted into the groove portion 23. Since the rotation stop position of the drum 20 is defined by the positions of the groove portions 23 given at equal intervals, one of the accurately positioned symbols is displayed on the front surface of the drum 20 whose rotation has been stopped. is there. Since the number of grooves 23 is the same as the number of symbols and they are arranged equally, all the display positions of each symbol of each drum 20 can be determined at a predetermined position on the front.

  In this way, the display device 1 sequentially stops the rotation of the three drums 20 forming a set by the three stop devices 30, and displays the combination of the three symbols on the front surface. Here, a detection device that detects the symbol displayed on the front side is provided, and the detection result can be transmitted to the control device, and a hit determination can be performed based on the detection result. In addition, in order to display a combination of symbols according to the result of the jackpot determination separately performed, it is also possible to detect the position of the rotating symbol and provide a stopper intrusion signal accordingly.

  After stopping all the three drums 20, in the motor stop step S3, the motor drive board stops the drive of the motor 2 based on the motor stop signal from the control device. Along with this, the rotation of the shaft 3 stops, and the rotation of the three discs 10 fixed to the shaft 3 also stops.

  In the stopper removal step S4, control is performed so that the stopper operation substrate returns the solenoid to the origin based on a stopper removal signal from a control device (not shown). Accordingly, as shown in FIG. 6C, the stopper shaft body 32 rotates in the returning direction, and the stopper 34 is removed from the groove portion 23. Thereby, the drum 20 can be rotated again in the motor start step S1.

  Thus, the display device 1 can repeatedly display a combination of three symbols by repeating the motor starting step S1 to the stopper removing step S4.

  It is also possible to repeatedly display a combination of three symbols on the display device 1 while the motor 2 is rotated. For example, after the motor start step S1 is performed once, the stopper entry step S2 and the stopper removal step S4 are repeated.

  Further, since the motor 2 can be rotated in both forward and reverse directions, the drum 20 can also be rotated in the reverse direction. Even in this case, the rotation of the drum 20 can be stopped by operating the stop device 30 in the same manner as described above to cause the stopper 34 to enter the groove 23. By utilizing this, a so-called return effect can be performed. For example, after stopping the two drums 20 in the stopper intrusion step S2, the motor 2 is temporarily stopped and then rotated in the reverse direction, and the remaining one drum 20 following this is reversely rotated. An effect of rotating the three drums 20 in reverse can also be performed.

  As described above, according to the present embodiment, it is possible to provide the drum-type display device 1 that can rotate the three drums 20 in synchronism with one motor 2 and can stop each drum body individually. .

  Since the drum end portion 21 into which the stopper 34 enters is arranged separately from the drum main portion 22, the drum main portion 22 does not have a member or the like that contacts the outer peripheral surface around which the design sheet is wound. It can prevent the pattern sheet from being contaminated or damaged.

  In this embodiment, three symbols are arranged on one drum 20, but the number of symbols can be increased. In that case, the symbols can be displayed at a predetermined position on the front surface of the display device 1 by arranging the groove portions 23 in the same number as the number of symbols and having a predetermined relationship with the positions of the symbols.

  In addition, by arranging at least one of the magnets 24 and the magnet attracting members 11 to be equal in number to the symbols, the drums 20 are similarly arranged with the relative angles of the respective drums 20 maintained, that is, the upper ends of the symbols. And the lower end can be rotated in synchronization with each other while keeping the bottom end aligned with each other. That is, the number of the magnet attracting members 11 may be the same as the number of symbols as in the above, and the number of the magnets 24 may be the same as the number of symbols, or both the magnet attracting members 11 and the magnets 24 may be the same as the number of symbols. It may be.

  Further, since the magnet and the magnet attracting member need only attract each other and maintain the attracting relationship, the magnet may be disposed on the disk 10 and the magnet attracting member may be disposed on the drum end 21. Furthermore, a magnet can be used as the magnet attracting member so that the magnets can attract each other. By using both as magnets, the rotational torque of the shaft 3 can be more strongly transmitted to the drum 20 via the disk 10, and for example, even if the rotation speed of the drum 20 is increased, stable rotation can be maintained. it can. Such a combination of the magnet attracting member 11 and the magnet 24 makes it easy to cause the drum 20 to follow the disc 10 during rotation, and to cut off the attraction relationship by stopping the drum 20 by the stop device 30. Depending on the distance from the drum end 21, a combination that provides a magnetic force capable of obtaining an appropriate attractive force can be selected as appropriate.

  As mentioned above, although the typical Example by this invention and the modification based on this were demonstrated, this invention is not necessarily limited to this, If it is those skilled in the art, the main point of this invention, or the scope of the attached claim Various alternative embodiments and modifications may be found without departing from the invention.
