Description

Technical Field

[0001] This invention belongs to the field of poker machine technology, and specifically relates to a poker machine. Background Technology

[0002] Currently, poker machines primarily focus on arranging the deck to save users time and enhance the entertainment experience. Existing poker machines can perform a series of actions, including shuffling, arranging, and dealing the cards.

[0003] Typically, a poker machine has a base and a panel. In the middle of the panel is a control panel, which is driven to rise and fall by a lifting mechanism. When the control panel rises, the card slot is exposed, allowing players to push the cards into the slot. When the control panel falls, it covers the card slot.

[0004] The lifting mechanism of poker machines in the existing technology usually adopts a structure of multiple hollow tubes connected to each other, which has the problems of complex structure, many moving parts, large space occupation of poker machine, and poor stability.

[0005] Poker machines have a card feeding mechanism that transports the cards. In the existing technology, the card feeding mechanism often uses a belt structure when feeding cards. The belt structure is complex and prone to slippage. Especially in the application of poker machines, because the cards are thin, the cards are easy to get stuck in the gaps at the edge of the belt. Summary of the Invention

[0131] The positive and progressive effects of this invention are as follows:

[0132] 1. This invention uses a rotating conveyor roller to feed cards, which has the advantages of simple structure and good card feeding stability compared with the conveyor belt structure.

[0133] The control panel lifting mechanism of the present invention adopts a threaded drive method. It only requires two threaded lifting rods to be sleeved together. The lifting purpose can be achieved by rotating one lifting rod to raise or lower the other lifting rod.

[0134] This invention has the advantages of simple structure, easy control and good stability, and can be well applied to poker machines.

[0135] 2. This invention employs an upper-layer card-feeding mechanism and a lower-layer card-feeding mechanism to form a two-layer card-feeding channel, resulting in a longer card-feeding channel and enabling better shuffling and card-feeding operations. When there are many cards, the design of the two-layer card-feeding channel allows the cards to be distributed in various locations, greatly avoiding the phenomenon of cards clustering together and the problem of cards being stuck together and difficult to play.

[0136] 3. The upper card delivery channel of the present invention guides the cards from the card delivery port to the lower card delivery channel through a card guide component. Before the cards are delivered, the disordered cards can be straightened by a rotating column so that the cards are all in a vertical position when they are delivered from the card delivery port.

[0137] 4. The lower conveyor roller of the present invention is a variable diameter structure with a large outer diameter at one end and a small outer diameter at the other end. When applied to a poker machine, the outer side is high and the inner side is low. Compared with the belt conveyor structure, the card feeding drive mechanism of the present invention drives the conveyor roller to rotate. When the card is conveyed on the conveyor roller, it is easy to control the card to run on the preset conveyor track, which makes it easy to sort the cards and avoids the phenomenon of the card being stuck on the outer side. There will also be no problems such as card jamming.

[0138] 5. The present invention uses a card feeding drive mechanism combined with a card feeding gear assembly to drive one or more conveying rollers to rotate, which has the advantages of simple structure, easy control, good stability and high card sorting efficiency.

[0139] 6. This invention incorporates a card-dispensing roller and a floating roller-like structure on the card-dispensing component. When a card passes between the two, it is dispensed under the floating of the roller-like structure, effectively limiting the number of cards dispensed and ensuring that only a single card is output between the card-dispensing roller and the roller-like structure. The card-dispensing design of this invention is simple in structure and has good stability.

[0140] 7. The present invention can guide a single card or several cards to the card-dispensing roller and roller-like structure in a better way through the card-dispensing guide plate, avoiding the card-dispensing jamming problem caused by a large number of cards being transported between the two.

[0141] 8. Since the card-dispensing roller and roller-like structures themselves do not have rotational force, the present invention, through the design of several transition rollers, can send the card body fed into the card-dispensing component to the space between the card-dispensing roller and roller-like structures via the driving mechanism of the card-dispensing drive mechanism. The card body sent out by the transition roller can smoothly and stably achieve the purpose of single card output under the action of the card-dispensing roller and roller-like structures.

[0142] 9. The card delivery guide plate of the present invention can limit the number of cards that pass through, so that a single card is delivered to the card dispensing component for dispensing.

[0143] 10. In this invention, the upstream section of the lower card delivery channel is designed with a structure in which the height gradually decreases from the card inlet along the card delivery direction, so that the upstream section of the lower card delivery channel has a certain slope. The cards delivered from the upper card delivery channel can slide down the slope better, avoiding the problem of the cards getting stuck in the upstream section and being difficult to deliver.

The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0174] It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0175] In the description of this invention, it should be noted that the directional terms such as "outer side", "middle section", "inner", "outer" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this invention.

[0176] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this invention, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0177] Example 1:

[0178] Reference Figures 1 to 5 This invention provides an upper card feeding mechanism, which is applied in a poker machine. The upper card feeding mechanism 10 includes a plurality of rotating upper conveying rollers 11, an upper card feeding channel 12, and a rotating column 13.

[0179] Several upper conveying rollers 11 are arranged at intervals on the upper card delivery channel 12 in a direction perpendicular to the upper card delivery channel 12. The upper conveying rollers 11 can rotate around their axial direction to drive the cards on the upper card delivery channel 12 forward.

[0180] The rotating column 13 is located on one side of the upper card delivery channel 12. When a card touches the rotating column 13, a force is applied to the card so that the length of the card tends to be in the direction of the upper card delivery channel 12.

[0181] Reference Figure 1When the card is delivered to the rotating column 13 in the upper card delivery channel 12, if the card is transported in the normal length direction, the card will not touch the rotating column 13 and will be normally delivered to the card delivery opening in the upper card delivery channel 12. If the card is transported at an angle, the inner side of the card will touch the rotating column 13. At this time, when the rotating column 13 moves counterclockwise, its direction of movement is the same as the card delivery direction of the upper card delivery channel 12. When the rotating column 13 moves the card that it touches on the side forward, it will turn and rotate the card until the card is turned to the normal length direction. At this time, the card will not touch the rotating column 13, the card will be straightened, the card will be separated from the rotating column 13, and the card will be normally delivered to the card delivery opening in the upper card delivery channel 12. When the rotating column 13 moves clockwise, its direction of movement is opposite to the card delivery direction of the upper card delivery channel 12. When the rotating column 13 moves the card it touches to the rear, it turns and moves the card. The card may continue to be delivered in the upper card delivery channel 12 behind the rotating column 13, or the card may gradually turn to the normal length direction. The card will not touch the rotating column 13. The card is turned upright, the card is separated from the rotating column 13, and the card is normally delivered to the card delivery port in the upper card delivery channel 12.

[0182] In this embodiment, the rotating column 13 can straighten the disordered cards, so that the length direction of the cards tends to be in the direction of the upper card delivery channel 12 and then they are sent out from the card delivery port.

[0183] In some embodiments, the distance between the rotating column 13 and the other side of the upper card delivery channel 12 is greater than the width of the card body and less than the length of the card body.

[0184] In some embodiments, the rotating column 13 is longitudinally disposed on one side of the upper card delivery channel 12.

[0185] In some embodiments, the upper card delivery channel 12 is an arc-shaped card delivery channel, and the rotating column 13 is located on the inner side of the arc-shaped upper card delivery channel 12.

[0186] In some embodiments, the annular upper card delivery channel 12 has an upstream end and an end end, the end end of the upper card delivery channel 12 has a card delivery port 121, and the rotating column 13 is located upstream of the card delivery port 121.

[0187] In some embodiments, the end of the arc-shaped upper card delivery channel 12 is lower than the upstream end, and the longitudinal space between the end and the upstream end forms the card delivery opening 121.

[0188] In some embodiments, the bottom surface of the arc-shaped upper card delivery channel 12 is an inclined card delivery channel with a higher outer side and a lower inner side.

[0189] At this time, the axial tilt angle of the upper conveyor roller 11 is consistent with the tilt angle of the upper card delivery channel 12, so that the axial direction of the upper conveyor roller 11 is parallel or approximately parallel to the width of the upper card delivery channel 12.

[0190] In some embodiments, the portion of the upper conveying roller 11 that contacts the plate body has a uniform diameter structure with the same outer diameter along the axial direction.

[0191] In some embodiments, the rotation direction of the rotating column 13 at the contact position with the card body is the same as or opposite to the rotation direction of the upper conveying roller 11 at the contact position with the card body.

[0192] like Figure 1 As shown, when the upper conveyor roller 11 rotates clockwise, the rotating column 13 also rotates clockwise to drive the card body to move upstream and turn into a longitudinal state, so that the card body can pass smoothly when it passes the rotating column 13 again.

[0193] Of course, when the upper conveyor roller 11 rotates clockwise, the rotating column 13 can also rotate counterclockwise to drive the card body to turn into a longitudinal state and be sent out from the card feeding port under the combined action of the upper conveyor roller 11.

[0194] In some embodiments, the outer side of the arc-shaped upper card delivery channel 12 has a card delivery seat wall 122 that can cooperate with the rotating column 13 to apply force to the card body so that the length direction of the card body tends to the direction of the upper card delivery channel 12.

[0195] In some embodiments, the rotating column 13 is a rotating column that can cooperate with the upper conveying roller 11 to apply force to the card body so that the length direction of the card body tends to the direction of the upper card delivery channel 12.

[0196] In some embodiments, the upper card feeding mechanism 10 further includes a card guide 14, which is located in front of the card feeding port 121 and guides the card body out of the card feeding port 121.

[0197] The cards, which have been arranged in a vertical position by the rotating column 13, can still be sent out in a vertical position under the guidance of the card guide 14.

[0198] In some embodiments, the guide card 14 is disposed at an angle in front of the card delivery port 121, with its upper part close to the rear side of the card delivery port 121 and its lower part far away from the rear side of the card delivery port 121.

[0199] In some embodiments, the upper card feeding mechanism 10 further includes a card feeding drive mechanism, which directly or indirectly drives the inner side of the upper conveying roller 11. The card feeding drive mechanism drives the upper conveying roller 11 to rotate, so as to drive the cards on the upper conveying roller 11 to move forward in a preset direction.

[0200] In some embodiments, the card feeding drive mechanism is connected to the inner side of the upper conveying roller 11 via a card feeding gear assembly.

[0201] In some embodiments, the outer side of the upper conveying roller 11 is fixed to the card-feeding seat 30 by a conveying bearing.

[0202] In some embodiments, the upper card delivery mechanism 10 further includes a card delivery drive mechanism, which directly or indirectly drives the rotating column 13, and the rotating column 13 is driven to rotate by the card delivery drive mechanism 15.

[0203] In some embodiments, the card feeding drive mechanism is connected to the rotating column 13 via a card feeding gear assembly.

[0204] In some embodiments, the card feeding drive mechanism 15 is a motor, which is fixed on the mounting base 40.

[0205] The mounting base 40 is fixed in one piece and can also serve as the mounting base for a poker machine.

[0206] In this invention, the card-feeding seat 30 is fixed relative to the upper conveying roller 11. The card-feeding seat 30 is usually located above the fixed seat 40 and is rotatable relative to the fixed seat 40, usually rotating about vertically, so that the card-feeding seat 30 and the upper conveying roller 11 thereon rotate about vertically to the target position.

[0207] In some embodiments, the upper conveying roller 11 and the rotating column 13 share a set of card feeding drive mechanism 15 and card feeding gear assembly 16.

[0208] The card-feeding gear assembly 16 includes multiple roller gears 165, face gears 166, and a sixth gear 167.

[0209] The card-feeding drive mechanism 15 is directly or indirectly connected to the face gear 166. Multiple roller gears 165 are fixed to one end of corresponding upper conveyor rollers 11, and these roller gears 165 are sequentially meshed with the periphery of the face gear 166, so that the card-feeding drive mechanism 15 drives the upper conveyor rollers 11 to rotate, thereby causing the cards on the upper conveyor rollers 11 to move forward in a preset direction. The card-feeding drive mechanism 15 is directly or indirectly connected to the sixth gear 167. The rotating column 13 is a gear component with gears on its outer peripheral surface, and the rotating column 13 is meshed with the sixth gear 167.

[0210] In some embodiments, the card-feeding gear assembly 16 further includes a first gear 161, a second gear 162, a third gear 163, and a fourth gear 164.

[0211] The first gear 161 is fixedly connected to the card feeding drive mechanism 15. The second gear 162 is meshed with the first gear 161. The third gear 163 is fixedly connected to the second gear 162. The fourth gear 164 is meshed with the third gear 163. The face gear 166 is fixedly connected to the fourth gear 164. The sixth gear 167 is fixedly connected to the fourth gear 164.

[0212] The card-feeding drive mechanism 15 drives the first gear 161 to rotate, which in turn drives the second gear 162 to rotate. The third gear 163, which is fixedly connected to the second gear 162, rotates accordingly. The third gear 163 drives the fourth gear 164 to rotate, which in turn drives the face gear 166, which is fixedly connected to the fourth gear 164, to rotate. The face gear 166 drives the roller gear 165 to rotate, which in turn drives the upper conveyor roller 11, which is fixedly connected to the roller gear 165, to rotate. The sixth gear 167, which is fixedly connected to the fourth gear 164, rotates accordingly, and drives the rotating column 13 to rotate.

[0213] Of course, the card-feeding gear assembly 16 can also be configured in other ways so that the card-feeding drive mechanism 15 can ultimately drive the upper conveying roller 11 to rotate and drive the rotating column 13 to rotate.

[0214] In some embodiments, the second gear 162 and the third gear 163 are fixedly connected by a first fixed shaft 168, which is fixed to the card feeding seat 30 by a first bearing.

[0215] In some embodiments, the fourth gear 164 is fixedly connected to the face gear 166 and the sixth gear 167 via a second fixed shaft 169, which is fixed to the fixed sleeve 41 of the fixed base 40 via a second bearing.

[0216] The fixing sleeve 41 is typically fixed to the fixing base 40, and preferably integrally formed with the fixing base 40. Therefore, the fixing sleeve 41 is in a fixed state, and it can also serve as the fixing sleeve for the poker machine. The fourth gear 164 and the face gear 166 can be fixed to the fixing sleeve 41 via the second bearing.

[0217] In some embodiments, the second fixed shaft 169 is a hollow shaft, and a second bearing is disposed inside the hollow shaft.

[0218] The fixed sleeve 41 is typically vertical in the axial direction and located in the middle of the poker machine. The hollow shaft design allows the fixed sleeve 41 to pass through the second fixed shaft 169, which is fixedly connected to the fixed sleeve 41 through an internal second bearing.

[0219] In some embodiments, the rotating column 13 is fixed to the card-feeding seat 30 by a third bearing.

[0220] In some embodiments, the upper card delivery channel 12 is disposed on the card delivery seat 30.

[0221] Example 2:

[0222] Reference Figures 6 to 11 This invention provides a lower card feeding mechanism, which is applied in a poker machine. The lower card feeding mechanism 20 includes a plurality of rotating lower conveying rollers 21 and an arc-shaped lower card feeding channel 22.

[0223] The lower card delivery channel 22 adopts an arc-shaped channel structure with a preset width. The bottom surface of this arc-shaped channel structure can be a planar structure. Preferably, the bottom surface of this arc-shaped channel structure is a spiral structure, and the height of the card inlet of the lower card delivery channel 22 is higher than the height of the card outlet. More preferably, the lower card delivery channel 22 has an upstream section, the upstream end of which has a card inlet, and the height of the upstream section gradually decreases from the card inlet along the card delivery direction. That is, in the lower card delivery channel 22, except for the upstream section which is a channel with a certain slope, the rest can be a planar structure without slope.

[0224] Several lower conveyor rollers 21 are arranged at intervals on the lower card delivery channel 22 in a direction perpendicular to the lower card delivery channel 22. The lower conveyor rollers 21 have a large end on the outer side and a small end on the inner side. The lower conveyor rollers 21 can rotate around their axial direction, so that the cards lying flat on the lower conveyor rollers 21 can always maintain an arc-shaped direction and move forward.

[0225] Since the lower conveyor rollers 21 are not arranged circumferentially but in an arc, a gap will be left, which can be used to place the card-dispensing component 23.

[0226] In some embodiments, the lower card feeding mechanism 20 further includes a card dispensing component 23, which is located on the side of the lower conveying roller 21 at the end of the lower card feeding channel 22. The card dispensing component 23 receives the cards conveyed from the lower conveying roller 21 and dispenses the cards.

[0227] In some embodiments, the lower conveying roller 21 is arranged on the lower card delivery channel 22 in a manner that is parallel to the axial direction and the horizontal direction.

[0228] In some embodiments, the outer diameter of the larger end is larger than the outer diameter of the smaller end.

[0229] In this embodiment, the lower conveyor roller 21 is typically positioned with its larger end on the outside and its smaller end on the inside. The travel distance from the larger end to the smaller end is the effective conveying width of the conveying channel, and the cards are conveyed on the lower card delivery channel 22. Due to the variable diameter structure design of the lower conveyor roller 21, which is higher on the outside and lower on the inside, it is easy to control the cards to run on the preset conveying track when they are conveyed on the lower conveyor roller 21. This facilitates card sorting, avoids the phenomenon of cards getting stuck on the outside, and eliminates problems such as card jamming.

[0230] In some embodiments, the outer diameter decreases smoothly and linearly from the large end to the small end, so that the card body can be stably and smoothly conveyed by the lower conveyor roller 21.

[0231] In some embodiments, the distance from the large end to the small end is greater than the width of the card and less than the length of the card.

[0232] In some embodiments, refer to Figure 8 The lower conveyor roller 21 includes a conveyor contact portion 211 and a conveyor shaft 212.

[0233] The conveying contact part 211 has a frustum-shaped structure, and a contact connection hole is provided along its axial direction. The conveying shaft 212 passes through the contact connection hole, and both ends of the conveying shaft 212 extend out of the conveying contact part 211.

[0234] The lower conveying roller 21 in this embodiment has the two parts mentioned above. The two parts can be made as one piece or separately. The two parts are connected together. When the conveying shaft 212 rotates along its axial direction, it drives the conveying contact part 211 to rotate along its axial direction, thereby driving the card body in contact with the conveying contact part 211 to be conveyed.

[0235] At this time, the end with the larger outer diameter of the conveying contact part 211 is considered to be the large end of the lower conveying roller 21, and the end with the smaller outer diameter of the conveying contact part 2111 is considered to be the small end of the lower conveying roller 21. The card body only contacts the conveying contact part 211 and does not contact the conveying shaft 212.

[0236] In some embodiments, the conveying contact 211 is an integral frustum-shaped structure.

[0237] In some embodiments, the conveying contact portion 211 has a multi-segment frustum-shaped structure.

[0238] The distance between each segment of the conveyor contact 211 is small, for example, less than the width of the plate body, preferably less than half the width of the plate body, and more preferably just enough to accommodate the timing belt.

[0239] The design of this embodiment is mainly for the synchronous belt installation function when the lower conveyor roller 21 is used as a driven conveyor roller.

[0240] In some embodiments, the conveying contact 211 is an elastic contact made of an elastic material.

[0241] In some embodiments, the conveying contact 211 is an elastic contact made of rubber or polyurethane material.

[0242] In some embodiments, one end of the lower conveying roller 21 near the large end is fixed to the card feeding seat 30 via a conveying bearing, and at least one end of the lower conveying roller 21 near the small end is connected to the card feeding drive mechanism.

[0243] In this embodiment, the card-feeding drive mechanism is located inside the lower conveyor roller 21, relative to the lower conveyor roller 21. When there are multiple lower conveyor rollers 21, they are arranged around the card-feeding drive mechanism. This design makes the overall structure of the present invention more compact.

[0244] In some embodiments, when the lower card feeding mechanism 20 has a plurality of lower conveying rollers 21, due to the limited arrangement of the lower conveying rollers 21, some of the lower conveying rollers 21 may not be able to connect with the card feeding drive mechanism. However, these lower conveying rollers 21 also need to rotate to drive the card body on them to be conveyed. Therefore, this embodiment adopts the following design:

[0245] Reference Figure 8 Among the plurality of lower conveyor rollers 21, at least one is an active conveyor roller 21a and at least one is a driven conveyor roller 21b, and at least one driven conveyor roller 21b is disposed on the side of the active conveyor roller 21a.

[0246] When there are multiple driven conveying rollers 21b, each driven conveying roller 21b can be set on the side of each driving conveying roller 21a. However, when there are too many driven conveying rollers 21b to meet this arrangement, the driven conveying rollers 21b can also be set on the side of another driven conveying roller 21b.

[0247] One end of the active conveyor roller 21a near the larger end is fixed to the card feeding seat 30 via a conveyor bearing, and the other end of the active conveyor roller 21a near the smaller end is connected to the card feeding drive mechanism. That is, the active conveyor roller 21a is driven to rotate by the card feeding drive mechanism. Of course, the card feeding drive mechanism can be directly connected to the active conveyor roller 21a, or it can be indirectly connected through a transmission component, such as a card feeding gear assembly.

[0248] Both ends of the driven conveyor roller 21b are fixed to the card-feeding seat 30 via conveyor bearings. The driven conveyor roller 21b is connected to the driving conveyor roller 21a or another driven conveyor roller 21b on its side via the conveyor timing belt 21c. That is, the power source of the driven conveyor roller 21b comes from the driving conveyor roller 21a or another driven conveyor roller 21b on its side.

[0249] In some embodiments, the lower card feeding mechanism 20 has a card feeding drive mechanism 24, which directly or indirectly drives the lower conveying roller 21. The lower conveying roller 21 is rotated by the card feeding drive mechanism 24 so as to drive the cards on the lower conveying roller 21 forward in an arc direction.

[0250] In some embodiments, the card feeding drive mechanism 24 is a motor, which is fixed on the mounting base 40.

[0251] The mounting base 40 is fixed in one piece and can also serve as the mounting base for a poker machine.

[0252] In some embodiments, the card feeding drive mechanism 24 is driven by the card feeding gear assembly 25 and connected to the lower conveyor roller 21.

[0253] In some embodiments, the card-feeding gear assembly 25 includes a plurality of roller gears 255 and a face gear 256.

[0254] The card feeding drive mechanism 24 is directly or indirectly connected to the face gear 256. Multiple roller gears 255 are fixed to one end of the corresponding multiple lower conveyor rollers 21. The multiple roller gears 255 are sequentially meshed with the periphery of the face gear 256 so that the card feeding drive mechanism 24 drives the lower conveyor rollers 21 to rotate, thereby driving the cards on the lower conveyor rollers 21 to move forward in a preset direction.

[0255] In some embodiments, the card-feeding gear assembly 25 further includes a first gear 251, a second gear 252, a third gear 253, and a fourth gear 254.

[0256] The first gear 251 is fixedly connected to the card feeding drive mechanism 24. The second gear 252 meshes with the first gear 251. The third gear 253 is fixedly connected to the second gear 252. The fourth gear 254 meshes with the third gear 253. The face gear 256 is fixedly connected to the fourth gear 254.

[0257] The card delivery drive mechanism 24 drives the first gear 251 to rotate, the first gear 251 drives the second gear 252 to rotate, the third gear 253, which is fixedly connected to the second gear 252, rotates accordingly, the third gear 253 drives the fourth gear 254 to rotate, the face gear 256, which is fixedly connected to the fourth gear 254, rotates accordingly, the face gear 256 drives the roller gear 255 to rotate, and the lower conveyor roller 21, which is fixedly connected to the roller gear 255, rotates accordingly.

[0258] Of course, the card feeding gear assembly 25 can also be configured in other ways so that the card feeding drive mechanism 24 ultimately drives the lower conveyor roller 21 to rotate. For example, the card feeding drive mechanism 24 is directly fixedly connected to the face gear 256. The card feeding drive mechanism 24 drives the face gear 256 to rotate, the face gear 256 drives the roller gear 255 to rotate, and the lower conveyor roller 21, which is fixedly connected to the roller gear 255, rotates accordingly.

[0259] In some embodiments, the second gear 252 and the third gear 253 are fixedly connected by a first fixed shaft 257, which is fixed to the card feeding seat 30 by a first bearing.

[0260] In this embodiment, the card feeding seat 30 is fixed relative to the lower conveying roller 21. The card feeding seat 30 is usually located above the fixed seat 40 and is rotatable relative to the fixed seat 40. It usually rotates around the vertical direction so that the card feeding seat 30, the lower conveying roller 21 and the card dispensing assembly 23 on it rotate, and the card dispensing assembly 23 is rotated to the target position to dispense cards.

[0261] In some embodiments, the fourth gear 254 and the face gear 256 are fixedly connected by a second fixed shaft 258, and the second fixed shaft 258 is fixed to the fixed sleeve 41 of the fixed seat 40 by a second bearing.

[0262] The fixing sleeve 41 is typically fixed to the fixing base 40, and preferably integrally formed with the fixing base 40. Therefore, the fixing sleeve 41 is in a fixed state, and it can also serve as the fixing sleeve for the poker machine. The fourth gear and the face gear 256 can be fixed to the fixing sleeve 41 via the second bearing.

[0263] In some embodiments, the second fixed shaft 258 is a hollow shaft, and a second bearing is disposed inside the hollow shaft.

[0264] The fixed sleeve 41 is typically vertical in the axial direction and located in the middle of the poker machine. The hollow shaft design allows the fixed sleeve 41 to pass through the second fixed shaft 258, which is fixedly connected to the fixed sleeve 41 through an internal second bearing.

[0265] In some embodiments, the lower card delivery channel 22 is disposed on the card delivery seat 30.

[0266] In some embodiments, the card-playing component 23 includes a card-playing roller 231 and a roller-like structure 232.

[0267] A floating gap is formed between the roller structure 232 and the card-dispensing roller 231 in the axial direction, allowing the card body to be squeezed through.

[0268] In some embodiments, the card-dispensing roller 231 and the roller-like structure 232 are disposed opposite to each other. The roller-like structure 232 is floatable relative to the card-dispensing roller 231, allowing the roller-like structure 232 to switch between a first state and a second state. In the first state, the roller-like structure 232 is in contact with the card-dispensing roller 231 or has a gap with the card-dispensing roller 231 that prevents the card from passing through. In the second state, a gap is formed between the roller-like structure 232 and the card-dispensing roller 231 for the card to pass through.

[0269] In some embodiments, a floating gap is formed between the roller structure 232 and the card-dispensing roller 231 in the axial direction, allowing only a single card to be squeezed through.

[0270] That is, the floating gap should preferably only allow a single card to pass through.

[0271] In some embodiments, the positional relationship between the card-dispensing roller 231 and the roller-like structure 232 can be as follows: Figures 10 to 11 As shown, the card-dispensing roller 231 is located below the roller structure 232. Of course, it is also possible to design the card-dispensing roller 231 to be located above the roller structure 232.

[0272] In some embodiments, the two ends of the card dispensing roller 231 are fixed to the card feeding seat 30 by card dispensing bearings.

[0273] The card-dispensing roller 231 in this embodiment can achieve passive rotation without being connected to a power source.

[0274] In some embodiments, the portion of the card-dispensing roller 231 that contacts the card body has a uniform diameter structure with the same outer diameter along the axial direction.

[0275] The structure of the card-dispensing roller 231 can be a conventional rotating roller that can rotate around its axial direction.

[0276] In some embodiments, elastic members 233 are connected to both ends of the roller structure 232, and elastic members 233 apply elastic force toward the card dispensing roller 231 to the roller structure 232, thereby forming a floating gap between the roller structure 232 and the card dispensing roller 231 in the axial direction, through which the card body can be squeezed and passed.

[0277] The elastic element 233 is preferably positioned on the side of the roller structure 232 away from the card-dispensing roller 231. For example, when the card-dispensing roller 231 is located below the roller structure 232, the two elastic elements 233 are respectively positioned on the upper sides of both ends of the roller structure 232.

[0278] In some embodiments, the elastic element 233 is a spring.

[0279] Of course, other elastic structures with elastic deformation capabilities can also be used for elastic component 233.

[0280] In some embodiments, the roller structure 232 has both ends inserted into the seat cavity of the roller structure support 2321, and one end of the elastic member 233 abuts against the inner wall of the seat cavity, while the other end abuts against the side end of the roller structure 232.

[0281] In some embodiments, the roller structure 232 is a rubber roller or one or more rollers arranged side by side.

[0282] When the roller structure 232 is a roller, it can be fixedly connected to the card-dispensing shaft. In this case, elastic elements can be connected to both ends of the card-dispensing shaft to make the roller structure 232 floatable.

[0283] In this embodiment, the roller structure 232 can achieve passive rotation without being connected to a power source. The roller structure 232 and the card-dispensing roller 231 rotate passively towards each other to deliver the cards.

[0284] In some embodiments, the card-dispensing assembly 23 further includes a card-dispensing guide plate 234, which is located behind the roller-like structure 232. The card-dispensing guide plate 234 has a card-dispensing arcuate guide surface 2341 facing the card-dispensing roller 231, and there is a fixed gap between the card-dispensing arcuate guide surface 2341 and the card-dispensing roller 231 for the card body to pass through.

[0285] The gap may allow one or more cards, such as two or three cards, to pass through, but preferably only a single card can pass through.

[0286] In some embodiments, the card-playing component 23 further includes a plurality of transition rollers 235 and a card-playing drive mechanism 26.

[0287] Several transition rollers 235 are arranged side by side behind the card-dispensing roller 231 along the card-dispensing direction. The transition rollers 235 are located on the side of the lower conveyor roller 21 at the end of the lower card-dispensing channel 22, and receive the cards conveyed from the lower conveyor roller 21. The card-dispensing drive mechanism 26 directly or indirectly drives the transition rollers 235, and the card-dispensing drive mechanism 26 drives the transition rollers 235 to rotate.

[0288] In this embodiment, the card body is driven by several transition rollers 235 to be sent between the card delivery roller 231 and the roller structure 232 along the card delivery direction. Under the conveying of the transition rollers 235, the card body continues to move forward, squeezing the roller structure 232 to make it float and form a floating gap that allows the card body to pass through. The card body continues to move forward and is successfully delivered.

[0289] In some embodiments, the two ends of the transition roller 235 are respectively fixed to the card feeding seat 30 by card feeding bearings.

[0290] In this embodiment, the transition roller 235 can be a rotating roller with the same specifications and structure as the card-dispensing roller 231. Unlike the card-dispensing roller 231, the transition roller 235 is connected to a power source, that is, the transition roller 235 is connected to the card-dispensing drive mechanism 26, and the card-dispensing drive mechanism 26 drives the transition roller 235 to rotate around its axial direction.

[0291] In some embodiments, the card-playing drive mechanism 26 is a motor, which is fixed on the mounting base 40.

[0292] In some embodiments, the card-playing drive mechanism 26 drives the connected transition roller 235 via the card-playing gear assembly 27.

[0293] In some embodiments, refer to Figure 10 and Figure 11 The card-playing gear assembly 27 includes a first bevel gear 271, a second bevel gear 272, a plurality of synchronous pulleys 273 and a plurality of card-playing synchronous belts 274.

[0294] The first bevel gear 271 is fixedly connected to the card-dispensing drive mechanism 26. The second bevel gear 272 meshes with the first bevel gear 271. Each synchronous pulley 273 is fixedly connected to one end of a corresponding transition roller 235. One of the synchronous pulleys 273 is fixedly connected to the second bevel gear 272. Adjacent synchronous pulleys 273 are connected by a card-dispensing synchronous belt 274.

[0295] The card-playing drive mechanism 26 drives the first bevel gear 271 to rotate, the first bevel gear 271 drives the second bevel gear 272 to rotate, the synchronous pulley 273 fixedly connected to the second bevel gear 272 rotates accordingly, and through each card-playing synchronous belt 274 drives other synchronous pulleys 273 to rotate, and finally drives each transition roller 235 to rotate accordingly.

[0296] In implementation, the synchronous pulleys fixed to each transition roller 235 can be determined to be either single-tooth or double-tooth synchronous pulleys based on the position of the synchronous pulleys fixed to the second bevel gear 272 and the number of transition rollers 235. For example, Figure 11 As shown, the rear synchronous pulley is fixedly connected to the second bevel gear 272, and the intermediate transition rollers adjacent to other transition rollers on both sides are fixedly connected to double-tooth synchronous pulleys. The other transition rollers are fixedly connected to single-tooth synchronous pulleys. The synchronous rotation of each transition roller can be achieved through two card-dispensing synchronous belts 274.

[0297] Of course, the card-playing gear assembly 27 can also be configured in other ways so that the card-playing drive mechanism 26 drives each transition roller 235 to rotate.

[0298] In some embodiments, refer to Figure 6The lower card feeding mechanism 20 also includes a card feeding guide plate 28, which is located in the lower card feeding channel 22. The card feeding guide plate 28 has a card feeding arc-shaped guide surface 281 facing the conveying direction. The card feeding arc-shaped guide surface 281 is arranged opposite to one of the lower conveying rollers 21 and there is a fixed gap between them for the card body to pass through.

[0299] The gap allows only a single card to pass through, so that the cards sent from the lower conveyor roller 21 to the card dispensing assembly 23 are single cards.

[0300] Example 3:

[0301] Reference Figures 12 to 23 This invention provides a control panel lifting mechanism, which is applied in a poker machine. The control panel lifting mechanism 70 includes a lifting drive mechanism 71, a first lifting rod 72, and a second lifting rod 73.

[0302] The lifting drive mechanism 71 has a rotating end, which is usually axially vertical, meaning that the rotating end rotates vertically.

[0303] The second lifting rod 73 is provided with an external thread 731. The second lifting rod 73 is connected to the rotating end of the lifting drive mechanism 71, and the second lifting rod 73 is driven to rotate by the rotation of the lifting drive mechanism 71.

[0304] The first lifting rod 72 has a hollow internal structure and an internal thread 721. The first lifting rod 72 is sleeved on the outside of the second lifting rod 73. The internal thread 721 of the first lifting rod 72 is threaded to the external thread 731 of the second lifting rod 73. The first lifting rod 72 can be used to connect to the control panel of the poker machine. The first lifting rod 72 and the control panel are raised and lowered by the rotation of the second lifting rod 73.

[0305] In some embodiments, the lifting drive mechanism 71 includes a motor 711, preferably a servo motor. The motor shaft of the motor 711 is a rotating end.

[0306] In some embodiments, the motor is fixed to the mounting base 40.

[0307] The mounting base 40 is fixed in one piece and can also serve as the mounting base for a poker machine.

[0308] In some embodiments, the rotating end of the motor 711 can be directly connected to the second lifting rod 73, or they can be indirectly connected through a transmission mechanism.

[0309] In this embodiment, the two are indirectly connected, specifically:

[0310] Reference Figures 13 to 22The lifting drive mechanism 71 also includes a lifting gear assembly, which includes a first lifting gear 741 and a second lifting gear 742. The first lifting gear 741 is fixed on the motor shaft of the motor 711, and the second lifting gear 742 is meshed with the first lifting gear 741.

[0311] In some embodiments, the second lifting gear 742 is connected to the second lifting rod 73.

[0312] When the motor 711 rotates, the first lifting gear 741 rotates, which in turn rotates the second lifting gear 742 that meshes with the first lifting gear 741, ultimately driving the second lifting rod 73 to rotate.

[0313] In some embodiments, the second lifting rod 73 is integrally formed with the second lifting gear 742.

[0314] In some embodiments, refer to Figure 20 and Figure 22 The lifting drive mechanism 71 also includes a sensing element 751 and a sensor 752. The sensing element 751 is disposed on the second gear 742 for lifting, and the sensor 752 faces the sensing element 751.

[0315] At this time, the sensor 751 rotates along with the second gear 742 for lifting. During its rotation, it is continuously detected by the sensor 752 to determine the number of rotations. Once the required number of rotations is met, the lifting drive mechanism 71 is driven to stop working.

[0316] The sensor 752 can be a Hall displacement sensor or a tunnel magnetoresistive sensor, etc., as is the case in the prior art, and the sensing element 751 can be a magnetic element, etc.

[0317] Of course, the sensing element 751 and the sensor 752 can also be used as sensing components in other existing technologies.

[0318] In the above-described design of this embodiment, there are no other designs or obstructions outside the first lifting rod 72, so that the first lifting rod 72 can be inserted into the fixed sleeve and limited and guided by the fixed sleeve.

[0319] In some embodiments, the sensing element 751 is disposed at the bottom of the second lifting gear 742, and the sensor 752 is disposed below the second lifting rod 73 and facing the sensing element 751.

[0320] In some embodiments, when the sensing element 751 is disposed at the bottom of the lifting second gear 742, it can be embedded, that is, a mounting groove is provided at the bottom of the lifting second gear 742, and the sensing element 751 is installed in the mounting groove. The bottom surface of the sensing element 751 is preferably embedded or flush with the bottom surface of the lifting second gear 742.

[0321] In some embodiments, refer to Figures 14 to 16 , Figures 19 to 20 A connecting bearing 76 is provided on the outside of the second lifting rod 73. The connecting bearing 76 is located above the second lifting gear 742. The second lifting rod 73 is fixed on the fixed base 40 through the connecting bearing 76.

[0322] In some embodiments, refer to Figure 12 and Figure 14 The control panel lifting mechanism 70 also includes a fixed sleeve 41 fixed on the fixed base 40. The fixed sleeve 41 is sleeved on the outside of the first lifting rod 72, and a guide block 411 is provided on the fixed sleeve 41 along the lifting direction.

[0323] The bottom end of the first lifting rod 72 is provided with several limiting flanges 722, and a spline groove 723 is formed between two adjacent limiting flanges 722. The limiting flanges 722 are restricted within the fixed sleeve 41, and the spline groove 723 is slidably connected to the guide block 411.

[0324] When the first lifting rod 72 passes through the fixed sleeve 41, the limiting flange restricts the lifting rod 72 inside the fixed sleeve 41, limiting the upward range of the first lifting rod 72 and preventing it from rising too much.

[0325] The spline groove 723 and the guide block 411 are slidably connected to provide stable guidance for the lifting and lowering of the first lifting rod 72.

[0326] In some embodiments, the fixing base 40 and the fixing sleeve 41 are integrally formed.

[0327] In some embodiments, a plurality of limiting flanges 722 are evenly arranged around the first lifting rod 72.

[0328] In some embodiments, the top end of the first lifting rod 72 is provided with a lifting connection part 77, and the first lifting rod 72 is connected to the control panel of the poker machine through the lifting connection part 77.

[0329] Specifically, the first lifting rod 72 and the lifting connection part 77 can be detachably fixed together by several fixing pins.

[0330] The lifting connection part 77 may be provided with several fixing holes for detachable connection with the control panel.

[0331] The lifting connection 77 is preferably a cone-shaped structure that is wider at the top and narrower at the bottom.

[0332] Example 4:

[0333] This invention provides a control panel lifting mechanism, which is applied in a poker machine.

[0334] The control panel lifting mechanism of this embodiment differs from that of Embodiment 3 in the following ways, while the rest is the same as that of Embodiment 3, and will not be described again here.

[0335] In this embodiment, the first lifting rod has an internal thread, and the lifting drive mechanism is connected to the first lifting rod. The lifting drive mechanism drives the first lifting rod to rotate, thereby driving the second lifting rod to rise and fall.

[0336] In some embodiments, the first lifting rod has a blind hole internal thread or a through hole internal thread.

[0337] In some embodiments, when the lifting drive mechanism has a lifting gear assembly, the second lifting gear is connected to the first lifting rod.

[0338] When the motor rotates, the first lifting gear rotates, which in turn rotates the second lifting gear that meshes with the first lifting gear, ultimately driving the first lifting rod to rotate.

[0339] In some embodiments, the first lifting rod and the second lifting gear are integrally formed.

[0340] In some embodiments, a connecting bearing is provided on the outside of the first lifting rod, and the first lifting rod is fixed to the fixed base by the connecting bearing.

[0341] In some embodiments, a fixing sleeve fixed on a fixing base is sleeved over the second lifting rod, and a guide block is provided on the fixing sleeve along the lifting direction.

[0342] The second lifting rod is provided with several limiting flanges, and a spline groove is formed between two adjacent limiting flanges. The limiting flanges are restricted in the fixed sleeve, and the spline groove is slidably connected to the guide block.

[0343] In practice, it is preferable to each of the first lifting rod and the fixing sleeve be fitted with a section of the second lifting rod to prevent mutual interference.

[0344] In some embodiments, the top end of the second lifting rod is provided with a lifting connection part, and the second lifting rod is connected to the control panel of the poker machine through the lifting connection part.

[0345] Example 5:

[0346] Reference Figures 24 to 28 This invention provides a poker machine, which includes a card feeding mechanism and a control panel lifting mechanism.

[0347] The card delivery mechanism includes a ring-shaped or arc-shaped card delivery channel. The center of the ring or arc of the card delivery channel forms a vertically connected clearance through hole, and the control panel lifting mechanism is located in the clearance through hole.

[0348] In some embodiments, the card feeding mechanism further includes a plurality of rotating conveying rollers, which are arranged at intervals on the card feeding channel in a manner perpendicular to the card feeding channel direction, so as to drive the cards on the card feeding channel forward.

[0349] In some embodiments, the control panel lifting mechanism includes a first lifting rod and a second lifting rod, the first lifting rod passing through a clearance through hole. The second lifting rod passes through the first lifting rod and is threadedly connected to the first lifting rod. The second lifting rod moves relative to the first lifting rod, such that one of the first and second lifting rods can extend out of the clearance through hole and the card feeding channel.

[0350] When applied to a poker machine, this embodiment typically includes a control panel fixed to a first or second lifting rod, which raises and lowers the control panel. A card feeding mechanism is located below the control panel. When the control panel rises to expose the card slot, the player pushes the cards into the slot, and the cards fall into the card feeding channel of the feeding mechanism for subsequent processing such as card arrangement. Therefore, in this embodiment, the first or second lifting rod can pass through the card feeding channel, raising and lowering the control panel to expose or cover the card slot.

[0351] In some embodiments, the poker machine further includes a fixed sleeve, which is fixed to a fixed base and passes through an clearance hole. A first lifting rod and a second lifting rod pass through the fixed sleeve, and the fixed sleeve separates the card feeding mechanism from the control panel lifting mechanism.

[0352] Each component of the card feeding mechanism and the control panel lifting mechanism can be fixed to a fixed sleeve using independent bearings, so that the card feeding mechanism can feed cards stably and the control panel lifting mechanism can lift and lower stably.

[0353] In some embodiments, the license plate delivery mechanism includes an upper license plate delivery mechanism and a lower license plate delivery mechanism.

[0354] The upper card feeding mechanism includes an annular upper card feeding channel and several rotating upper conveyor rollers. The upper conveyor rollers are arranged at intervals on the upper card feeding channel with their axial direction perpendicular to the upper card feeding channel, so as to drive the cards on the upper card feeding channel forward.

[0355] The lower-level card feeding mechanism includes an arc-shaped lower-level card feeding channel and several rotating lower-level conveyor rollers. The lower-level card feeding channel is located below the upper-level card feeding channel, and its inlet is connected to the outlet of the upper-level card feeding channel. The lower-level conveyor rollers are arranged at intervals on the lower-level card feeding channel, with their axial directions perpendicular to the lower-level card feeding channel.

[0356] The bypass through-hole is formed at the center of the upper card delivery channel and the center of the arc of the lower card delivery channel.

[0357] In some embodiments, the upper card delivery mechanism adopts the upper card delivery mechanism 10 provided in each embodiment of Embodiment 1.

[0358] In some embodiments, the lower card delivery mechanism is the lower card delivery mechanism 20 provided in each embodiment of Embodiment 2. The lower card delivery channel 22 of the lower card delivery mechanism 20 receives the cards delivered from the card delivery port 121.

[0359] In some embodiments, the upper card feeding mechanism 10 and the lower card feeding mechanism 20 share the same set of card feeding drive mechanisms, which directly or indirectly drive the upper conveying roller, the rotating column and the lower conveying roller respectively.

[0360] In some embodiments, the card-feeding drive mechanism is a motor.

[0361] In some embodiments, the card feeding drive mechanism is connected to the upper conveying roller, the rotating column, and the lower conveying roller respectively via a card feeding gear assembly.

[0362] In some embodiments, refer to Figures 25 to 28 The card-feeding gear assembly 50 includes two face gears, multiple roller gears, and a sixth gear 51. The two face gears are the upper gear 52a and the lower gear 52b, the multiple roller gears serve as the upper roller gear 53a, and the multiple roller gears serve as the lower roller gear 53b.

[0363] The card-feeding drive mechanism 60 is directly or indirectly connected to the upper gear 52a and the lower gear 52b, respectively. The gear faces of the gears on the upper gear 52a and the lower gear 52b face the same direction. Of course, the gear faces of the gears on the two gears can be set on the top or bottom surface according to actual needs. Figure 28 As shown, the gear surfaces of both the upper gear 52a and the lower gear 52b are located on the top surface.

[0364] The upper roller gear 53a is sequentially meshed with the periphery of the upper gear 52a, and the lower roller gear 53b is sequentially meshed with the periphery of the lower gear 52b. One end of each upper conveying roller 11 is fixedly connected to the upper roller gear 53a, and one end of each lower conveying roller 21 is fixedly connected to the lower roller gear 53b.

[0365] The card delivery drive mechanism 60 is directly or indirectly connected to the sixth gear 51. The rotating column 13 is a gear component with gears on its outer peripheral surface, and the rotating column 13 is meshed with the sixth gear 51.

[0366] In some embodiments, there are two upper gears 52a, one upper gear 52a is located above or below the outer side of the other upper gear 52a, and one or more upper roller gears 53a are meshed on both upper gears 52a.

[0367] When the card body is thin and there is only one upper gear 52a, there may be a problem that the arrangement of the upper roller gear 53a along the circumference is restricted. Therefore, two upper gears 52a are designed. Most of the upper roller gears 53a are meshed and connected to the inner upper gear 52a, and a small part of the upper roller gears 53a are meshed and connected to the outer upper gear 52a.

[0368] In some embodiments, the outer diameter of the upper roller gear 53a meshing with the lower upper gear 52a is larger than the outer diameter of the upper roller gear 53a meshing with the upper upper gear 52a.

[0369] In some embodiments, the card-feeding gear assembly 50 further includes a first gear 54, a second gear 55, a third gear 56, and a fourth gear 57.

[0370] The first gear 54 is fixedly connected to the card feeding drive mechanism 60. The second gear 55 meshes with the first gear 54. The third gear 56 is fixedly connected to the second gear 55. The fourth gear 57 meshes with the third gear 56. The upper gear 52a and the lower gear 52b are fixedly connected to the fourth gear 57 respectively. The sixth gear 51 is fixedly connected to the fourth gear 57.

[0371] In some embodiments, the second gear 55 and the third gear 56 are fixedly connected by a first fixed shaft 58, which is fixed to the card feeding seat 30 by a first bearing.

[0372] In this embodiment, the card-feeding seat 30 is fixed relative to the upper conveying roller 11 and the lower conveying roller 21. The card-feeding seat 30 is usually located above the fixed seat 40 and is rotatable relative to the fixed seat 40. It usually rotates around the vertical direction so that the card-feeding seat 30 and the upper conveying roller 11, the lower conveying roller 21 and the card-dispensing assembly 23 on it rotate, and the card-dispensing assembly 23 is rotated to the target position to dispense cards.

[0373] Specifically, the clearance through hole also extends through the card delivery seat 30. The card delivery seat 30 and the fixing sleeve 41 of the fixing seat 40 can be connected by a bearing so that when the card delivery seat 30 rotates, the fixing seat 40 and the fixing sleeve 41 remain relatively stationary.

[0374] In some embodiments, the fourth gear 57 is fixedly connected to the upper gear 52a, the lower gear 52b and the sixth gear 51 via a second fixed shaft 59, and the second fixed shaft 59 is fixed to the fixed sleeve 41 of the fixed base 40 via a second bearing.

[0375] The fixing sleeve 41 is typically fixed to the fixing base 40, and preferably integrally formed with the fixing base 40. Therefore, the fixing sleeve 41 is in a fixed state, and it can also serve as the fixing sleeve for the poker machine. The fourth gear 57, the upper gear 52a, the lower gear 52b, and the sixth gear 51 can be fixed to the fixing sleeve 41 via the second bearing.

[0376] In some embodiments, the second fixed shaft 59 is a hollow shaft, and a second bearing is disposed inside the hollow shaft.

[0377] The fixed sleeve 41 is typically vertical in the axial direction and located in the middle of the poker machine. The hollow shaft design allows the fixed sleeve 41 to pass through the second fixed shaft 59, which is fixedly connected to the fixed sleeve 41 through an internal second bearing.

[0378] In some embodiments, the control panel lifting mechanism adopts the control panel lifting mechanism 70 provided in each embodiment of Embodiment 3 or the control panel lifting mechanism provided in each embodiment of Embodiment 4.

[0379] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
