Description

Technical Field

[0001] The present invention belongs to the technical field of mahjong machines, and in particular relates to a mahjong machine and a flat-pushing card-dealing device thereof. Background Art

[0002] Mahjong, as a leisure and entertainment tool, is widely loved by the people and has been listed as a sports competition event. After the mahjong tiles on the four sides of a traditional mahjong machine rise to the tabletop, they are parallel to the edges of the four sides of the tabletop, and the mahjong tiles are very close to the table edge, with an unreasonable layout. Before touching the tiles, players need to manually move the mahjong tiles forward and obliquely to a proper position. During the process of moving the mahjong tiles, the mahjong tiles are likely to fall, bringing inconvenience to the players.

[0003] Patent documents with publication numbers such as CN117982870A, CN117982871A, and CN117982868A disclose a mahjong machine. The card-supporting plate transmission mechanism in its flat-pushing card-dealing device includes: card-dealing curve cams, two card-dealing curve cams are respectively installed on the left and right sides at the bottom of the card-supporting plate; the left and right ends at the bottom of the card-supporting plate are slidably connected up and down with a card-dealing seat through two guide shafts or sliding sleeves; card-dealing rocker arms, two card-dealing rocker arms respectively cooperate with the two card-dealing curve cams for movement; a card-dealing rocker arm shaft, the card-dealing rocker arm shaft is rotatably installed on the card-dealing seat, and the two card-dealing rocker arms are respectively fixed on the two card-dealing rocker arm shafts; a card-dealing driving cam, the card-dealing driving cam is installed on the card-dealing seat and is driven to rotate by a flat-pushing card-dealing motor; a card-dealing connecting rod, the card-dealing connecting rod is driven by the card-dealing driving cam to move; the card-dealing connecting rod drives the two card-dealing rocker arm shafts to rotate synchronously, so as to drive the two card-dealing rocker arms to rotate to drive the card-supporting plate to move up and down. In this way, the volume of the card-dealing curve cam is small, the installation position of the card-dealing rocker arm is high and it takes intermittent swings, and then the card-dealing rocker arm is suspended and erected forward by extending the card-dealing rocker arm shaft, so that the card-dealing connecting rod and the card-dealing driving cam can be set more backward, making the card-supporting plate transmission mechanism occupy less shuffling space, increasing the diameter of the shuffling disk and increasing the shuffling space. This can not only improve the shuffling efficiency, but also reduce the probability of mahjong tiles hitting each other on the shuffling disk, achieving the effect of reducing shuffling noise. However, the movement of the connecting rod is prone to jamming, the two card-dealing rocker arms are prone to uneven force, the movement stability and synchronism are poor, and the installation and maintenance debugging are difficult. Moreover, the suspended card-dealing rocker arm shaft and the cam connecting rod driving mechanism result in insufficient support strength and weak load-bearing capacity of the card-supporting plate.

[0004] Patent documents such as CN119656572A, CN119680179A, CN119701316A, and CN119524380A disclose a mahjong machine. The card-supporting plate transmission mechanism in its flat-pushing card-dealing device includes: a card-dealing seat and a card-supporting plate for sending multiple stacks of mahjong cards to the tabletop at one time; two card-dealing curve cams, which are respectively installed on the left and right sides at the bottom of the card-supporting plate; two card-dealing rocker arms, which respectively cooperate with the two card-dealing curve cams in motion; two card-dealing rocker arm shafts, which are rotatably installed on the card-dealing seat, and the card-dealing rocker arms are fixedly arranged on the card-dealing rocker arm shafts; two card-dealing rocker arm cams, which are fixedly connected to the card-dealing rocker arm shafts, and cam grooves are provided on the card-dealing rocker arm cams; two first gears, which are rotatably installed on the card-dealing seat, and the first gears are in cooperative transmission with the card-dealing rocker arm cams through cranks; the two first gears are driven by a flat-pushing card-dealing motor to rotate synchronously. However, in the process of the cooperative transmission between the first gear and the card-dealing rocker arm cam through the crank in this structure, the roller (or roller) on the crank moves back and forth between the two ends of the card-dealing rocker arm cam, and the rotation axis (card-dealing rocker arm shaft) of the card-dealing rocker arm cam is set at one of its ends, while the first gear rotates at a constant speed. This causes the swing of the card-dealing rocker arm cam not to be uniform, and the lifting process of the card-supporting plate is not uniform either. The speed of some cam curve segments is too fast, resulting in unstable and unreliable lifting motion; moreover, the transmission cooperation between the roller (or roller) on the crank and the cam groove on the card-dealing rocker arm cam is a loose fit (unilateral limit fit), and it is impossible to achieve bilateral limit fit for the entire cam curve, and the transmitted torque is limited, which will also cause unstable operation. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a mahjong machine and its flat-pushing card-dealing device. Its card-supporting plate transmission mechanism adopts all-gear transmission, enhances the torque transmission ability and load-bearing capacity, improves the stability and reliability of the lifting motion of the card-supporting plate, has a more reasonable transmission structure, and is more convenient for maintenance and installation.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A flat pushing and card placing device for a mahjong machine, comprising a card placing seat, a card receiving plate for receiving and arranging multiple stacks of mahjong tiles, a card supporting plate for sending multiple stacks of mahjong tiles onto the tabletop at one time, and a card pushing plate for flat pushing multiple stacks of mahjong tiles on the card receiving plate onto the card supporting plate. A card storage channel for storing and arranging multiple stacks of mahjong tiles is formed on the card receiving plate. The card supporting plate is located inside the card receiving plate and can move up and down. The card pushing plate is located outside the card receiving plate and pushes the cards from outside to inside. It also includes a card supporting plate transmission mechanism for driving the card supporting plate to move up and down. The card supporting plate transmission mechanism includes: two card placing curve cams, which are respectively installed on the left and right sides of the bottom of the card supporting plate. There are card placing curve cam grooves on the two card placing curve cams; two card placing rocker arms, which respectively cooperate with the two card placing curve cams; two card placing rocker arm shafts, which are installed on the card placing seat in a rotatable manner. The card placing rocker arm is fixedly connected or integrally formed with the card placing rocker arm shaft; two card placing rotating gears, which are installed on the card placing seat in a rotatable manner. The card placing rotating gear is fixedly connected or integrally formed with the card placing rocker arm shaft; two first gears, which are installed on the card placing seat in a rotatable manner. The first gear is an incomplete gear, with a toothed part and a toothless part on the first gear. The first gear is in meshing transmission with the card placing rotating gear: when the toothed part on the first gear meshes with the card placing rotating gear, the first gear drives the card placing rotating gear to rotate; when the toothless part on the first gear meshes with the card placing rotating gear, the card placing rotating gear does not rotate; the two first gears are driven by a flat pushing and card placing motor to rotate synchronously.

[0008] Preferably, the first gear is driven by a flat pushing and card placing motor to rotate reciprocally, and the maximum rotation range of the first gear is 120° - 280°.

[0009] Preferably, a card placing rocker arm, a card placing rocker arm seat and a card placing rotating gear are sequentially sleeved on the card placing rocker arm shaft from front to back, and the card placing rocker arm shaft and the card placing rocker arm seat can rotate relative to each other.

[0010] Preferably, the card placing rotating gear is a sector gear.

[0011] Preferably, it further includes two second gears, which mesh with each other and rotate synchronously. The first gear is a double - linked gear. The toothed part and the toothless part are arranged on the front gear of the double - linked gear. The rear gear of the double - linked gear meshes with the second gear for transmission, and one of the second gears is driven by a flat pushing and card placing motor to rotate.

[0012] Preferably, it further includes a card pushing plate transmission mechanism for driving the card pushing plate to flat push. The card pushing plate transmission mechanism includes a flat pushing cam and a flat pushing swing rod. The upper end of the flat pushing swing rod is movably connected to the card pushing plate, and the lower end of the flat pushing swing rod is hinged to the card placing seat. The flat pushing and card placing motor drives the flat pushing swing rod to swing back and forth through the flat pushing cam, thereby driving the card pushing plate to move back and forth to implement card pushing.

[0013] Preferably, the flat push cam is coaxially fixed and synchronously rotated with the first gear or the second gear; the cam curve of the flat push cam includes a non-driving section and a driving section: when the flat push cam is in the non-driving section, it does not drive the card pushing plate to move. At this time, the toothed part on the first gear meshes with the upper card rotating gear for transmission, and the first gear drives the upper card rotating gear to rotate, thereby driving the card supporting plate to move up and down; when the flat push cam is in the driving section, it drives the card pushing plate to push the cards or reset. At this time, the toothless part on the first gear cooperates with the upper card rotating gear, and the upper card rotating gear does not rotate.

[0014] Preferably, the card pushing plate transmission mechanism further includes a card pushing frame and a flat push slider. The flat push slider slides back and forth on the card pushing frame. The card pushing plate is fixed on the flat push slider. The upper end of the flat push swing rod is movably connected to the flat push slider. The lower end of the flat push swing rod is hinged to the upper card seat through the flat push swing rod shaft. A flat push rocker arm is fixed on the flat push swing rod shaft. The swinging end of the flat push rocker arm is movably matched with the flat push cam through a roller. The flat push card placing motor drives the flat push swing rod to swing back and forth through the flat push cam, thereby driving the flat push slider and the card pushing plate to slide back and forth to implement card pushing.

[0016] A mahjong machine includes the flat push card placing device of the mahjong machine as described above.

[0017] Due to the adoption of the above technical solutions in the present invention, the card supporting plate transmission mechanism using all-gear transmission has a more reasonable transmission structure, smoother movement coordination, larger transmission torque, better load-bearing capacity of the card supporting plate, better stability and reliability of the lifting movement of the card supporting plate, more convenient installation and debugging, more convenient maintenance and disassembly, and lower manufacturing cost.

[0056] Embodiment 1:

[0057] As Figure 1 and Figure 2 shown, a flat-pushing card-dealing device of a mahjong machine includes a card-holding plate 72 for receiving and arranging multiple stacks of mahjong tiles, a card-supporting plate 74 for sending multiple stacks of mahjong tiles onto the tabletop at one time, and a card-pushing plate 73 for flat-pushing multiple stacks of mahjong tiles on the card-holding plate 72 to the card-supporting plate 74. A card-storing channel for storing and arranging multiple stacks of mahjong tiles is formed on the card-holding plate 72. The card-supporting plate 74 is located inside the card-holding plate 72 and can move up and down, and the card-pushing plate 73 is located outside the card-holding plate 72 and pushes the cards from outside to inside. It further includes a card-dealing seat 70 and a flat-pushing card-dealing motor 71. The card-holding plate 72 is fixedly arranged on the card-dealing seat 70. A card-dealing transmission mechanism is provided on the card-dealing seat 70. The flat-pushing card-dealing motor 71 drives the card-pushing plate 73 to translate and push the cards and drives the card-supporting plate 74 to move up and down for card dealing through the card-dealing transmission mechanism. The card-dealing transmission mechanism includes a card-supporting plate transmission mechanism for driving the card-supporting plate 74 to move up and down and a card-pushing plate transmission mechanism for driving the card-pushing plate 73 to flat-push. In other embodiments, the card-holding plate 72 can also be arranged on the card-dealing seat 70 in a manner that it can move up and down and is driven to move up and down by the flat-pushing card-dealing motor 71.

[0058] In this embodiment, one end of the card-holding plate 72 extending along the length direction is the card inlet of the card-storing channel. A card-holding block of the card-pushing device is arranged outside the card inlet. A side baffle is provided at the other end of the card-holding plate 72 extending along the length direction. The front and rear blocks of the card-storing channel are respectively a front baffle 742 and the card-pushing plate 73. The front baffle 742 is fixedly connected to or integrally formed with the card-supporting plate 74.

[0059] In this embodiment, as Figure 1 shown, the card-supporting plate transmission mechanism includes:

[0060] Two card-dealing curve cams 744, which are respectively installed on the left and right sides at the bottom of the card-supporting plate 74. Card-dealing curve cam grooves 7441 are provided on the two card-dealing curve cams 744;

[0061] Two upper card swing arms 743, and the two upper card swing arms 743 are respectively in cooperative movement with two upper card curve cams 744;

[0062] Two upper card swing arm shafts 745, and the upper card swing arm shafts 745 are installed on the upper card seat 70 in a rotatable manner;

[0063] Two upper card rotating gears 746, and the upper card rotating gears 746 are installed on the upper card seat 70 in a rotatable manner, and the upper card rotating gears 746 are fixedly connected or integrally formed with the upper card swing arm shafts 745;

[0064] Two first gears 747, and the first gears 747 are installed on the upper card seat 70 in a rotatable manner. The first gears 747 are incomplete gears, and tooth portions 7471 and toothless portions 7472 are provided on the first gears 747. The first gears 747 are in cooperative transmission with the upper card rotating gears 746: when the tooth portions 7471 on the first gears 747 are engaged with the upper card rotating gears 746 for transmission, the first gears 747 drive the upper card rotating gears 746 to rotate; when the toothless portions 7472 on the first gears 747 are in cooperation with the upper card rotating gears 746, the upper card rotating gears 746 do not rotate; the two first gears 747 are driven by a flat push upper card motor 71 to rotate synchronously.

[0065] In this way, by adopting a full gear transmission mechanism, the structure is reasonable, the movement is smooth, the transmission torque is large, the stability and reliability of the lifting movement of the card supporting plate are better, the installation and debugging are more convenient, the maintenance and disassembly are also more convenient, and the manufacturing cost is lower.

[0066] In this preferred embodiment, during the lifting process of the card supporting plate 74, the two upper card swing arms 743 rotate synchronously in opposite directions, and the two first gears 747 rotate synchronously in opposite directions. In this way, the lifting structure of the card supporting plate is reasonable and the movement is smooth.

[0067] In this preferred embodiment, the first gears 747 are driven by the flat push upper card motor 71 to rotate reciprocally, and the maximum rotation range of the first gears 747 is 120° to 280°. In this way, the first gears drive the upper card rotating gears and the upper card swing arms to rotate reciprocally (forward and reverse), which can further reduce the occupation and influence of the upper card swing arms and the upper card rotating gears on the shuffling space.

[0068] In this preferred embodiment, an upper card swing arm 743, an upper card swing arm shaft seat, and an upper card rotating gear 746 are sequentially sleeved on the upper card swing arm shaft 745 from front to back, and the upper card swing arm shaft 745 and the upper card swing arm shaft seat can rotate relative to each other. In this way, not only can the occupation and influence of the upper card rotating gears on the shuffling space be reduced, but also the transmission structure is more stable and reliable.

[0069] Preferably, in this embodiment, the bottom of the upper card swing arm shaft seat is supported by the shuffling barrel or the card feeding device, or by an independent support column which is fixedly connected or integrally formed with the upper card seat. This can maximize the support strength and load-bearing capacity of the card holding plate.

[0070] Preferably, in this embodiment, the front end of the upper card swing arm shaft 745 is fixedly connected or integrally formed with the upper card swing arm 743, the rear end of the upper card swing arm shaft 745 is fixedly connected or integrally formed with the upper card rotating gear 746, and the upper card swing arm shaft 745 is installed on the upper card seat 70 through a bearing. This can maximize the avoidance of the upper card swing arm and the upper card rotating gear occupying the shuffling space.

[0071] Preferably, in this embodiment, the two upper card rotating gears 746 are sector gears to reduce costs and save space. In other embodiments, the two upper card rotating gears 746 can also be complete gears.

[0072] Preferably, in this embodiment, it further includes two second gears 748. The two second gears 748 mesh with each other and rotate synchronously. The first gear 747 is a double gear. The toothed part 7471 and the toothless part 7472 are arranged on the front gear of the double gear. The rear gear of the double gear meshes with the second gear 748 for transmission. One of the second gears 748 is driven to rotate by the flat push upper card motor 71. In this way, the first gear adopts a double gear structure and meshes with the second gear and the upper card rotating gear respectively for transmission, with low manufacturing cost, compact structure, small occupied space, stable and reliable transmission, and convenient installation and maintenance. Among them, the double gear can be integrally formed, or the front gear and the rear gear can be formed separately and then fixedly connected into one body.

[0073] Preferably, in this embodiment, as Figure 2 shown, the card pushing plate transmission mechanism includes a card pushing frame 731, a flat push slider 7311, a flat push cam 732 and a flat push swing rod 734. The flat push slider 7311 slides back and forth on the card pushing frame 731 along the guide rod. The card pushing plate 73 is fixed on the flat push slider 7311. The upper end of the flat push swing rod 734 is movably connected to the flat push slider 7311. The lower end of the flat push swing rod 734 is hinged to the upper card seat 70 through the flat push swing rod shaft 735. A flat push swing arm 733 is fixed on the flat push swing rod shaft 735. The swinging end of the flat push swing arm 733 is movably matched with the flat push cam 732 through a roller. One first gear 748 is driven to rotate by the flat push upper card motor 71, and the other first gear 748 is fixedly connected and rotates synchronously with the flat push cam 732. Thus, the flat push upper card motor 71 drives the flat push slider 7311 to slide back and forth through the flat push cam 732 and the flat push swing rod 734 to implement card pushing. Further preferably, the flat push swing arm 733 is arranged between the flat push upper card motor 71 and the flat push cam 732. Further preferably, a card pushing cover plate is fixedly arranged above the card pushing plate 73.

[0074] In another embodiment of the pushing card plate transmission mechanism, the upper end of the flat pushing swing rod 734 is hinged to the pushing card plate 73, the lower end of the flat pushing swing rod 734 is hinged to the upper card seat 70 through the flat pushing swing rod shaft 735, a flat pushing rocker arm 733 is fixed on the flat pushing swing rod shaft 735, the swinging end of the flat pushing rocker arm 733 is movably matched with the flat pushing cam 732 through a roller, and the flat pushing upper card motor 71 drives the flat pushing swing rod 734 and the pushing card plate 73 to swing back and forth through the flat pushing cam 732 to implement pushing the card. In other embodiments, the pushing card plate transmission mechanism can also refer to various embodiments disclosed in patent documents such as the patent publications with the publication numbers of CN109381855A, CN109794059A, CN112023390A, CN114247127A, CN114146397A, CN117982871A, etc.

[0075] In this embodiment, preferably, the flat pushing cam 732 is coaxially fixed and synchronously rotated with a second gear 748. In other embodiments, the flat pushing cam 732 can also be coaxially fixed and synchronously rotated with a first gear 747, or be independently driven by the flat pushing upper card motor. As Figure 3 and Figure 4 shown, the cam curve of the flat pushing cam 732 includes a non-driving section 7321 and a driving section 7322: when the flat pushing cam 732 is in the non-driving section 7321, it does not drive the pushing card plate 73 to move. At this time, the toothed part 7471 on the first gear 747 meshes with the upper card rotating gear 746 for transmission, and the first gear 747 drives the upper card rotating gear 746 to rotate so as to drive the card supporting plate 74 to move up and down; when the flat pushing cam 732 is in the driving section 7322, it drives the pushing card plate 73 to push the card or reset. At this time, the toothless part 7472 on the first gear 747 cooperates with the upper card rotating gear 746, and the upper card rotating gear 746 does not rotate, and the card supporting plate 74 does not move up and down.

[0076] In this embodiment, preferably, as Figure 3 and Figure 4 shown, the angular range a of the non-driving section 7321 on the flat pushing cam 732 is 70° to 130°, and the angular range b of the driving section 7322 is 70° to 130°; as Figure 5 and Figure 6 shown, the angular range of the toothed part 7471 on the first gear 747 is greater than the angular range a of the non-driving section 7321 on the flat pushing cam 732, and the angular range of the toothless part 7472 is greater than the angular range b of the driving section 7322 on the flat pushing cam 732. In this way, the flat pushing upper card speed is reasonable, and the operation is stable and reliable.

[0077] In other embodiments of the flat pushing cam, as Figure 20 shown, after reaching the highest point in the driving section 7322, a card pushing in-place holding section 7323 is further provided. This setting ensures the card pushing in-place, as well as the stability and reliability of the card pushing, and reduces the assembly difficulty and debugging difficulty.

[0078] In this embodiment, preferably, a signal source magnet is provided on the flat push cam 732, and a control circuit board 737 for detecting the motion state of the flat push cam is installed on the upper card seat 70. Two control elements for sensing the signal source magnet are provided on the control circuit board 737, and the two control elements respectively correspond to the signal for the tray board to stay at the highest position and the signal for the motor to start reversing. In other embodiments, the control circuit board 737 can also be fixedly arranged on the cam cover 736, as Figure 21 shown, the control circuit board 737 is fixed behind the cam cover 736, which makes disassembly, installation and maintenance more convenient. In other embodiments, the signal source magnet can also be provided on the upper card rotating gear 746, the first gear 747 or the second gear 748.

[0079] The operation process of the flat push upper card device in this embodiment is as follows:

[0080] When the mahjong tiles on the card holding plate 72 are stored completely, as Figures 7 to 9 shown, the tray board 74 is in the raised state. When flat pushing and putting on the card, the flat push card putting motor 71 drives the second gear 748 to rotate forward 70° - 130°, the second gear 748 drives the first gear 747 to rotate backward 70° - 130°, the toothed part 7471 of the first gear 747 meshes with the upper card rotating gear 746 to drive the upper card rotating gear 746 to rotate forward 60° - 90°, the upper card rotating gear 746 drives the upper card rocker arm 743 to rotate forward 60° - 90°, and the tray board 74 descends; at the same time, the flat push cam 732 is driven by the flat push card putting motor 71 to rotate forward 70° - 130°, and the swing end roller of the flat push rocker arm 733 moves on the non-driving section 7321 of the flat push cam 732, and the card pushing plate 73 does not move.

[0081] The tray board 74 moves from the highest point to the lowest point, as Figures 10 to 12 shown. At this time, the toothed part 7471 on the first gear 747 just disengages from the meshing with the upper card rotating gear 746, and the toothless part 7472 starts to cooperate with the upper card rotating gear 746, and the tray board 74 stops moving; the swing end roller of the flat push rocker arm 733 moves to the junction position of the non-driving section 7321 and the driving section 7322 of the flat push cam 732, and the card pushing plate 73 is ready to start pushing the card.

[0082] As Figures 13 to 15As shown, the flat-push card-dealing motor 71 drives the second gear 748 to continue rotating forward 70° to 130°. The second gear 748 continues to drive the first gear 747 to rotate backward 70° to 130°. The toothless part 7472 of the first gear 747 does not drive the card-dealing rotating gear 746 to rotate. The card-dealing rotating gear 746 and the card-dealing rocker arm 743 do not rotate. The card-holding plate 74 remains stationary at the lowest point to receive the cards. At the same time, the flat-push cam 732 is driven by the flat-push card-dealing motor 71 to continue rotating forward 70° to 130°. The swing-end roller of the flat-push rocker arm 733 moves on the driving section 7322 of the flat-push cam 732, moving from the lowest point to the highest point, thereby driving the card-pushing plate 73 to flat-push the mahjong tiles on the card-receiving plate 72 onto the card-holding plate 74.

[0083] Then, the flat-push cam 732 is driven by the flat-push card-dealing motor 71 to rotate backward 70° to 130°. The swing-end roller of the flat-push rocker arm 733 moves on the driving section 7322 of the flat-push cam 732, returning from the highest point along the original path to the lowest point. The card-pushing plate 73 resets, as Figure 16 and Figure 17 shown. At the same time, the flat-push card-dealing motor 71 drives the second gear 748 to rotate backward 70° to 130°. The second gear 748 drives the first gear 747 to rotate forward 70° to 130°. The toothless part 7472 of the first gear 747 does not drive the card-dealing rotating gear 746 to rotate. The card-dealing rotating gear 746 and the card-dealing rocker arm 743 do not rotate. The card-holding plate 74 remains stationary at the lowest point. As the first gear 747 rotates back to its original position, the toothed part 7471 of the first gear 747 is ready to start meshing with the card-dealing rotating gear 746.

[0084] The flat-push card-dealing motor 71 drives the second gear 748 to continue rotating backward 70° to 130°. The second gear 748 continues to drive the first gear 747 to rotate forward 70° to 130°. The toothed part 7471 of the first gear 747 meshes with and drives the card-dealing rotating gear 746. The first gear 747 drives the card-dealing rotating gear 746 to rotate backward 60° to 90°. The card-dealing rotating gear 746 drives the card-dealing rocker arm 743 to rotate backward 60° to 90°. The card-holding plate 74 rises to the highest point, thereby lifting the mahjong tiles on it onto the tabletop, as Figure 18 and Figure 19 shown. At the same time, the flat-push cam 732 is driven by the flat-push card-dealing motor 71 to continue rotating backward 70° to 130°. The swing-end roller of the flat-push rocker arm 733 moves on the non-driving section 7321 of the flat-push cam 732, moving away from the junction position between the non-driving section 7321 and the driving section 7322. The card-pushing plate 73 remains stationary.
