Description

Technical Field

[0001] This invention relates to the field of card dealing machines, specifically to a card dealing machine with an internal card flipping structure and a card flipping method thereof. Background Technology

[0002] In traditional card games, the dealing process is crucial for ensuring fairness and smooth gameplay. With the continuous development of automation and mechanization in entertainment equipment, card dealing machines have emerged as a substitute for manual dealing. These machines aim to improve dealing efficiency, ensure randomness in dealing, and reduce errors caused by human factors. Card dealing machines utilize the friction between rollers and cards to extract cards one by one as the rollers rotate. The cards are then guided to the dealing slot via specific rails or channels, completing the dealing action and automating the process, thus increasing the speed of dealing.

[0003] For example, the Chinese authorized patent with publication number CN 221998841 U (A Card Dealer with 8-Wheel Card Feeder) includes a card dealer body, with two mounting brackets fixedly connected inside the card dealer body. A mounting plate is fixedly connected inside the card dealer body and to one side of the two mounting brackets. The mounting plate and the two mounting brackets are rotatably connected. The beneficial effect of this invention is that a drive source drives a drive mechanism, which in turn drives a rotating shaft. When the rotating shaft rotates, it drives the conveyor wheels to rotate, thus completing the card dealing process. Compared to the traditional card dealing structure, this device has a larger holding area, can accommodate various card sizes, and uses silicone material for the conveyor wheels, which not only increases the friction between the wheels and the cards but also makes the card dealing process more stable.

[0004] While the existing technologies mentioned above can ensure the stability of the card dealing process, for some card games that require cards to be dealt face-up or face-down in a certain number, current card dealing machines only focus on separating and dealing cards from the deck and cannot automatically perform the flipping function. They can only deal cards face-up, requiring manual flipping by the operator. Therefore, it is necessary to develop a card dealing machine with an internal card flipping structure to effectively manage the card's posture during the dealing process. Summary of the Invention

[0005] The purpose of this invention is to provide a card dealing machine with an internal card flipping structure and a card flipping method thereof, in order to solve the problem mentioned in the background art that in some card games that require the cards to be on both sides, existing card dealing machines are difficult to automatically perform the flipping function, and can only deal cards on the same side, requiring personnel to manually flip the cards.

[0010] Preferably, a second drive motor is installed on one side of the front end of the card dealing chamber, and a ninth rotating gear is connected to the output shaft of the second drive motor. The intermediate shaft of the bidirectional threaded rod extends to one side of the card dealing chamber and is connected to a tenth rotating gear. The tenth rotating gear and the ninth rotating gear are connected by a fourth transmission belt.

[0011] Preferably, a first drive motor is installed on the other side of the front end of the card dealing chamber. The output shaft of the first drive motor is connected to a first rotating gear. The rear end of the card receiving plate is slotted and rotatably connected to a first card-pulling wheel via a shaft. The front end of the card receiving plate is slotted and rotatably connected to a second card-pulling wheel via a shaft. The first and second card-pulling wheels are corresponding to each other. The intermediate shaft of the first card-pulling wheel extends to the other side of the card dealing chamber and is connected to the second rotating gear. The second rotating gear and the first rotating gear are connected by a first transmission belt. The intermediate shaft of the first card-pulling wheel extends to one side of the card dealing chamber and is connected to a third rotating gear. The intermediate shaft of the second card-pulling wheel extends to one side of the card dealing chamber and is connected to a fourth rotating gear. The fourth rotating gear and the third rotating gear are connected by a second transmission belt.

[0012] Preferably, a lower rotating roller is rotatably connected to the lower end of the card dispensing compartment. The intermediate shaft of the lower rotating roller extends to one side of the card dispensing compartment and is connected to a sixth rotating gear. The intermediate shaft of the second card-dispensing wheel extends to the other side of the card dispensing compartment and is connected to a fifth rotating gear. The fifth rotating gear and the sixth rotating gear are connected by a third transmission belt. An upper rotating roller is rotatably connected to the upper end of the card dispensing compartment. A second rectangular groove is provided at the connection position between the end face of the card dispensing compartment and the lower rotating roller and the upper rotating roller for the lower rotating roller and the upper rotating roller to pass through. The intermediate shaft of the upper rotating roller extends to the other side of the card dispensing compartment and is connected to an eighth rotating gear. The intermediate shaft of the lower rotating roller extends to the other side of the card dispensing compartment and is connected to a seventh rotating gear. The eighth rotating gear and the seventh rotating gear are meshed together.

[0013] Preferably, the upper support platform is equipped with an outer decorative shell, the card dispensing compartment forms a card dispensing channel inside, the card dispensing channel is connected to the inclined channel, the front end face of the card dispensing compartment is provided with a card dispensing groove, and the card dispensing channel, inclined channel, through channel, card dispensing through groove and card receiving plate have the same inclination angle.

[0014] Preferably, a first reversing motor is installed at the rear end of one side of the support base, a drive gear is installed at the output shaft end of the first reversing motor, an intermediate limiting tube is fixed in the center inside the support base, a rotating gear ring is rotatably connected to the outside of the intermediate limiting tube, the rotating gear ring is fixed at the middle of the lower end of the upper support platform, and an outer rotating shell is fixed around the lower end of the upper support platform.

[0015] A method for flipping playing cards includes the following steps:

[0016] Step 1: The second drive motor drives the ninth rotating gear to rotate, which in turn drives the bidirectional threaded rod to rotate through the intermediate transmission relationship. This causes the two upper sliding blocks to move outward synchronously. The retraction of the scissor lifting bracket causes the lower sliding block to move outward along the lower fixed rod, pulling the card pressing mechanism upward along the fixed upright rod. The distance between the lower protrusion and the card set placement cavity increases, placing the card set inside the card set placement cavity. The second drive motor then drives the ninth rotating gear to rotate in the opposite direction, causing the lower protrusion to move downward and press against the upper end of the card set.

[0017] Step 2: The first drive motor drives the first rotating gear to rotate, which in turn drives the second card-dispensing wheel and the first card-dispensing wheel to rotate through the intermediate transmission relationship. The rotation of the second card-dispensing wheel and the first card-dispensing wheel moves the cards at the bottom of the card set. The cards pass through the card-dispensing slot, through the channel and the inclined channel to reach the card-dispensing compartment.

[0018] Step 3: The first drive motor works, which in turn drives the lower and upper rotating rollers to rotate through the intermediate transmission relationship. The lower and upper rotating rollers rotate synchronously towards the card direction, pushing the cards in the card dispensing chamber to move and be dispensed through the card dispensing slot.

[0019] Step 4: After a card is dealt, the first reversing motor drives the drive gear to rotate, and through the meshing relationship between the drive gear and the rotating gear ring, it drives the upper support platform and its upper structure connected to the rotating gear ring to rotate.

[0020] Step 5: The first drive motor and the first reversing motor work alternately to deal cards; after a card is dealt, the second drive motor drives the ninth rotating gear to rotate in the opposite direction, and under the elastic action of the pressure spring, the lower protrusion always exerts downward pressure on the card set;

[0021] Step Six: When it is necessary to flip the playing card, when the playing card enters the passage under the pushing action, the second reversing motor drives the playing card flipping mechanism to rotate. The playing card is located in the passage, and the middle rotating shaft and the outer fixed plate rotate along the annular rotating groove and the annular limiting groove, and the playing card is flipped 180 degrees.

[0022] Step 7: The first drive motor operates to push out the next card. The next card pushes the flipped card, causing it to reach between the lower and upper rotating rollers and be pushed out as the lower and upper rotating rollers rotate.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] (1) In this invention, by setting an internal card flipping mechanism, the cards are flipped 180 degrees according to actual needs during the dealing process, thereby effectively managing the dealing posture of the cards during the dealing process, enriching the function of the card dealing machine, meeting more diverse scenarios and special needs, eliminating the need for manual card flipping, and solving the problem that existing card machines cannot automatically perform the flipping function in some card games that require the front and back sides of the cards, and can only deal the cards on the same side, requiring personnel to manually flip the cards.

[0025] (2) In this invention, a card-pressing mechanism is provided. Through the cooperation of a bidirectional threaded rod, a scissor lifting bracket, and other structures, the distance between the lower protrusion and the card set inside the card set placement cavity can be controlled, thereby achieving stable fixation and downward pressure on the card set. During the card dealing process, the card set is not easily displaced, ensuring the continuity and accuracy of card dealing.

[0026] (3) In this invention, multiple card-dispensing wheels and rotating rollers work together. The card-dispensing wheels move the cards at the bottom of the deck, and the rotating rollers push the cards to move, ensuring that the cards can be dealt stably and smoothly, effectively avoiding problems such as card jamming and unsmooth card dealing.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0041] Please see Figures 1-12This invention provides an embodiment of a card dealing machine with an internal card flipping structure, comprising a support base 1, which provides a stable support foundation for the entire card dealing machine. A rotating bracket 5 is rotatably connected to the upper end of the support base 1. The rotating bracket 5 includes an upper support platform 6, and an outer decorative shell 9 is installed on the outer periphery of the upper end of the upper support platform 6, serving both aesthetic and protective functions for the internal structure. A first reversing motor 2 is installed at the rear end of one side inside the support base 1. A drive gear 3 is installed at the output shaft end of the first reversing motor 2. A centrally fixed intermediate limiting tube 4 is fixed inside the support base 1, and a rotating gear ring 8 is rotatably connected to the outside of the intermediate limiting tube 4. The rotating gear ring 8 is fixed at the lower middle of the upper support platform 6, and an outer rotating shell 7 is fixed on the outer periphery of the lower end of the upper support platform 6. After a card is dealt, the first reversing motor 2 drives the drive gear 3 to rotate, and through the meshing relationship between the drive gear 3 and the rotating gear ring 8, the upper support platform 6 and its upper structure connected to the rotating gear ring 8 rotate.

[0042] The upper support platform 6 has a card-dealing chamber 10 connected to its rear end via a support member. The lower surface of the card-dealing chamber 10 is configured as a card-receiving plate 11, which is tilted forward and downward to facilitate the sliding of playing cards under gravity. A card-dealing passage groove 14 is formed along the front end of the card-receiving plate 11 on the front surface of the card-dealing chamber 10, providing a channel for the playing cards to be issued. An external fixed tube 15 with closed sides is connected to the middle of the upper end of the upper support platform 6 via a support member. An internal moving cavity 16 is provided inside the external fixed tube 15, providing internal space for the playing cards to flip. The upper front end of the upper support platform 6 is connected to a card-dispensing chamber 18 via a support member. The external fixed tube 15, the card-dealing chamber 10, and the card-dispensing chamber 18 are all fixedly connected. An inclined channel 17 is formed at the connection between the external fixed tube 15 and the card-dispensing chamber 18, allowing the playing cards to smoothly enter the card-dispensing chamber 18 through the inclined channel 17.

[0043] A second reversing motor 37 is installed on one side of the outer fixed tube 15. An inner card flipping mechanism 38 is installed inside the inner actuating cavity 16 along the output shaft end of the second reversing motor 37. The inner card flipping mechanism 38 includes a rotating component 39, which forms a passageway 40 through its front and rear ends. Cards pass through the passageway 40 during the dealing process. Fixing rings 41 are fixed on the left and right sides of the front and rear ends of the upper and lower ends of the rotating component 39. A middle rotating shaft 42 is rotatably connected between the two fixing rings 41 at each end. An outer fixed plate 44 is fixed at both ends of the middle rotating shaft 42. A limiting rotating roller 43 is fixed in the middle of the outside of the middle rotating shaft 42. A first rectangular groove is provided at the connection position between the end face of the card dispensing chamber 18 and the limiting rotating roller 43 for the limiting rotating roller 43 to pass through. An annular rotating groove 45 is opened on the inner side of the outer fixed tube 15 along the rotation trajectory of the middle rotating shaft 42. An annular limiting groove 46 is opened on the inner side of the outer fixed tube 15 along the rotation trajectory of the outer fixed plate 44. When the cards need to be flipped, the second reversing motor 37 drives the card flipping mechanism 38 to rotate. The cards are pushed into the passageway 40. The four limiting rollers 43 are located at the top, bottom, front, and back positions of the cards, which limit and guide the cards. The middle rotating shaft 42 and the outer fixed plate 44 rotate along the annular rotating groove 45 and the annular limiting groove 46 to ensure that the cards are stable in position during the flipping process and will not deviate, so that they can be flipped smoothly 180 degrees.

[0044] Two guide plates 12 are symmetrically fixed on both sides of the upper end of the card receiving plate 11. The guide plates 12 have a straight end and an outwardly flared end, with the outwardly flared end connected to the rear end of the straight end. Fixed uprights 47 are fixed at four points (front, back, left, right) inside the card dealing chamber 10. A card pressing mechanism 48 is installed inside the card dealing chamber 10. The card pressing mechanism 48 includes an upper connecting plate 49 and a lower pressing plate 50. The upper connecting plate 49 is located above the lower pressing plate 50. The upper connecting plate 49 and the lower pressing plate 50 slide along the fixed uprights 47, allowing the card pressing mechanism 48 to move up and down, thus fixing and pressing down the card set. A pressure spring 53 is fixed between the upper connecting plate 49 and the lower pressing plate 50 along the outside of the fixed uprights 47. The pressure spring 53 provides stable elastic force, ensuring that the lower pressing plate 50 always exerts downward pressure on the card set. An inclined plate 51 is integrally connected to the front end of the lower pressing plate 50. The inclined plate 51 is tilted forward and upward, which facilitates the smooth entry of the cards into the card set placement cavity 13. A lower protrusion 52 is integrally connected to the lower middle of the pressure plate 50. The height of the lower protrusion 52 is the same as the height of the straight end of the guide plate 12, and the width of the lower protrusion 52 is the same as the distance between the straight ends of the two guide plates 12. A card set placement cavity 13 is formed inside the card chamber 10 along the area between the lower protrusion 52, the card receiving plate 11, and the two guide plates 12. The card set is placed in the card set placement cavity 13, and during the dealing process, the lower protrusion 52 can stably press down on the card set to prevent the card set from shifting, thus ensuring the accuracy and continuity of the dealing.

[0045] A lower rectangular groove 54 is formed on the upper end face of the upper connecting plate 49. A lower fixing rod 55 is horizontally fixed inside the lower rectangular groove 54. Lower sliding blocks 56 are symmetrically arranged on both sides of the lower fixing rod 55. The lower sliding blocks 56 slide along the lower rectangular groove 54 and the lower fixing rod 55. A lower fixing seat 57 is fixed to the upper end of the lower sliding block 56. An upper rectangular groove 60 is formed through the upper end face of the card dealing chamber 10 along the upper end of the lower rectangular groove 54. A bidirectional threaded rod 61 is rotatably connected inside the upper rectangular groove 60. Upper sliding blocks 64 are symmetrically arranged on both sides of the bidirectional threaded rod 61. The upper sliding blocks 64 are threadedly connected to the bidirectional threaded rod 61. An upper fixing seat 65 is fixed to the lower end of the upper sliding blocks 64. A scissor lifting bracket 66 is rotatably connected between the two upper fixing seats 65 and the two lower fixing seats 57 through a shaft. A second drive motor 58 is installed on one side of the front end of the card dealing chamber 10. The output shaft of the second drive motor 58 is connected to a ninth rotating gear 59. The intermediate shaft of the bidirectional threaded rod 61 extends to one side of the card dealing chamber 10 and is connected to a tenth rotating gear 62. The tenth rotating gear 62 and the ninth rotating gear 59 are connected by a fourth transmission belt 63. When the card set needs to be placed into the card set placement cavity 13, the second drive motor 58 drives the ninth rotating gear 59 to rotate. Through the transmission relationship between the ninth rotating gear 59, the tenth rotating gear 62 and the fourth transmission belt 63, the bidirectional threaded rod 61 connected to the tenth rotating gear 62 is driven to rotate. The upper sliding block 64, threadedly connected to the bidirectional threaded rod 61, moves outward synchronously. Through the axial rotational connection between the upper fixed seat 65, the scissor lifting bracket 66, and the lower fixed seat 57, the lower sliding block 56, fixed to the lower fixed seat 57, moves outward along the lower fixed rod 55. This pulls the card-pressing mechanism 48 upward along the fixed upright rod 47, increasing the distance between the lower protrusion 52 and the card set placement cavity 13, facilitating the placement of the card set within the cavity. After the card set is placed, the second drive motor 58 drives the ninth rotating gear 59 to rotate in the opposite direction, causing the lower protrusion 52 to move downward and press against the upper end of the card set. This method of controlling the lifting and lowering of the card-pressing mechanism 48 via the bidirectional threaded rod 61 and the scissor lifting bracket 66 enables displacement control, ensuring that the pressure of the lower protrusion 52 on the card set is moderate, preventing damage to the cards and guaranteeing the stability of the card set during the dealing process.

[0046] The card dispensing compartment 18 forms a card dispensing channel 19, which is connected to the inclined channel 17. The front end of the card dispensing compartment 18 is provided with a card dispensing groove 20. The card dispensing channel 19, the inclined channel 17, the passage channel 40, the card dispensing passage groove 14 and the card receiving plate 11 have the same inclination angle. This design of the same angle ensures that the playing cards can slide smoothly in each channel, reducing the resistance of the playing cards during the transmission process.

[0047] A first drive motor 21 is installed on the other side of the front end of the card-dealing chamber 10. The output shaft of the first drive motor 21 is connected to a first rotating gear 22. A slot is cut at the rear end of the end face of the card-bearing plate 11, and a first card-pushing wheel 23 is rotatably connected to it via a shaft. A slot is cut at the front end of the end face of the card-bearing plate 11, and a second card-pushing wheel 26 is rotatably connected to it via a shaft. The first card-pushing wheel 23 and the second card-pushing wheel 26 are corresponding to each other. The intermediate shaft of the first card-pushing wheel 23 extends to the other side of the card-dealing chamber 10 and is connected to a second rotating gear 24. The second rotating gear 24 and the first rotating gear 22 are connected by a first transmission belt 25. The intermediate shaft of the first card-pushing wheel 23 extends to one side of the card-dealing chamber 10 and is connected to a third rotating gear 27. The intermediate shaft of the second card-pushing wheel 26 extends to one side of the card-dealing chamber 10 and is connected to a fourth rotating gear 28. The fourth rotating gear 28 and the third rotating gear 27 are connected by a second transmission belt 29. A lower rotating roller 31 is rotatably connected to the lower end of the card dispensing chamber 18. The intermediate shaft of the lower rotating roller 31 extends to one side of the card dispensing chamber 18 and is connected to a sixth rotating gear 32. The intermediate shaft of the second card-dispensing wheel 26 extends to the other side of the card dispensing chamber 10 and is connected to a fifth rotating gear 30. The fifth rotating gear 30 and the sixth rotating gear 32 are connected by a third transmission belt 33. An upper rotating roller 34 is rotatably connected to the upper end of the card dispensing chamber 18. A second rectangular groove is provided at the connection position between the end face of the card dispensing chamber 18 and the lower rotating roller 31 and the upper rotating roller 34 for the lower rotating roller 31 and the upper rotating roller 34 to pass through. The intermediate shaft of the upper rotating roller 34 extends to the other side of the card dispensing chamber 18 and is connected to an eighth rotating gear 36. The intermediate shaft of the lower rotating roller 31 extends to the other side of the card dispensing chamber 18 and is connected to a seventh rotating gear 35. The eighth rotating gear 36 and the seventh rotating gear 35 are meshed together. During the card dealing process, the first drive motor 21 drives the first rotating gear 22 to rotate. Through the transmission relationship between the first rotating gear 22, the second rotating gear 24, and the first transmission belt 25, the first card-dispensing wheel 23 and the third rotating gear 27, connected to the second rotating gear 24, rotate. Then, through the transmission relationship between the third rotating gear 27, the fourth rotating gear 28, and the second transmission belt 29, the second card-dispensing wheel 26, connected to the fourth rotating gear 28, rotates. The rotation of the second card-dispensing wheel 26 and the first card-dispensing wheel 23 moves the cards at the bottom of the card set. The cards pass through the card-dispensing slot 14, through the channel 40, and the inclined channel 17 to reach the card-dispensing compartment 18. Since the fifth rotating gear 30 is coaxial with the second card-dispensing wheel 26, it rotates. Through the transmission relationship between the fifth rotating gear 30, the sixth rotating gear 32, and the third transmission belt 33, the lower rotating roller 31, connected to the sixth rotating gear 32, rotates. Because the seventh rotating gear 35 on the other side of the lower rotating roller 31 is meshed with the eighth rotating gear 36, it drives the upper rotating roller 34 connected to the eighth rotating gear 36 to rotate coaxially and in opposite directions. The lower rotating roller 31 and the upper rotating roller 34 rotate synchronously towards the card direction, pushing the cards in the card dispensing chamber 18 to move and be dispensed through the card dispensing slot 20.This multi-stage transmission and the coordinated operation of multiple card-pulling wheels and rotating rollers ensure that the playing cards are subjected to stable and uniform force during the dealing process, achieving smooth dealing.

[0048] The card flipping method of the present invention includes the following steps:

[0049] Step 1: The second drive motor 58 drives the ninth rotating gear 59 to rotate, which in turn drives the bidirectional threaded rod 61 to rotate through the intermediate transmission relationship. This causes the two upper sliding blocks 64 to move outward synchronously. The retraction of the scissor lifting bracket 66 causes the lower sliding block 56 to move outward along the lower fixed rod 55, pulling the card pressing mechanism 48 upward along the fixed upright rod 47. The distance between the lower protrusion 52 and the card set placement cavity 13 increases, placing the card set inside the cavity. The second drive motor 58 then drives the ninth rotating gear 59 to rotate in the opposite direction, causing the lower protrusion 52 to move downward and press against the upper end of the card set.

[0050] Step 2: The first drive motor 21 drives the first rotating gear 22 to rotate, which in turn drives the second card-dispensing wheel 26 and the first card-dispensing wheel 23 to rotate through the intermediate transmission relationship. The rotation of the second card-dispensing wheel 26 and the first card-dispensing wheel 23 moves the cards at the bottom of the card set. The cards pass through the card-dispensing slot 14, through the channel 40 and the inclined channel 17 to reach the card-dispensing compartment 18.

[0051] Step 3: The first drive motor 21 operates. Since the fifth rotating gear 30 is coaxial with the second card-dispensing wheel 26, it drives the fifth rotating gear 30 to rotate. Through the transmission relationship between the fifth rotating gear 30, the sixth rotating gear 32 and the third transmission belt 33, the lower rotating roller 31 connected to the sixth rotating gear 32 is driven to rotate. Since the seventh rotating gear 35 on the other side of the lower rotating roller 31 is meshed with the eighth rotating gear 36, it drives the upper rotating roller 34 connected to the eighth rotating gear 36 to rotate coaxially and in opposite directions, pushing the cards in the card-dispensing chamber 18 to move and be dispensed through the card-dispensing slot 20.

[0052] Step 4: After a card is dealt, the first reversing motor 2 drives the drive gear 3 to rotate. Through the meshing relationship between the drive gear 3 and the rotating gear ring 8, the upper support platform 6 connected to the rotating gear ring 8 and its upper structure rotate, thus realizing the flexible adjustment of the card dealing direction.

[0053] Step 5: The first drive motor 21 and the first reversing motor 2 work alternately to deal cards. After a card is dealt, the second drive motor 58 drives the ninth rotating gear 59 to rotate in the opposite direction. Under the elastic action of the pressure spring 53, the lower protrusion 52 always exerts downward pressure on the card set, ensuring the stability of the card set during the dealing process and avoiding problems such as card set displacement.

[0054] Step Six: When it is necessary to flip the cards, as the cards enter the passageway 40 under the pushing action, the second reversing motor 37 drives the card flipping mechanism 38 to rotate, and the cards are always located in the passageway 40, and the cards are flipped 180 degrees.

[0055] Step 7: The first drive motor 21 operates to push out the next card. The next card pushes the flipped card, causing it to reach between the lower rotating roller 31 and the upper rotating roller 34. As the lower rotating roller 31 and the upper rotating roller 34 rotate, the card is pushed out. At this time, the next card enters the passage 40.

[0056] When the cards do not need to be flipped, the cards enter the passageway 40 and, under the driving force, will travel along the inclined passageway 40 to the card dispenser 18, and be pushed out as the lower rotating roller 31 and the upper rotating roller 34 rotate. When the cards need to be flipped, since the length of the passageway 40 is greater than the length of the cards, when the cards slide along the passageway 40, the card flipping mechanism 38 is driven to rotate. The cards are blocked by the inner wall of the outer fixed tube 15. After the cards are flipped 180 degrees, since there is no initial driving force, the speed of falling along the passageway 40 is slow. The next card gives a driving force to the flipped card, making it quickly reach between the lower rotating roller 31 and the upper rotating roller 34.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
