[0002] A mahjong machine is a machine used to automatically sort, stack, and lift cards, usually used in mahjong games. It can save time, reduce manual sorting, stacking, and placing operations, and ensure the fairness of the game process.
[0003] In the prior art, card receiving recognition and control are all carried out by using photoelectric eyes. The disadvantages of this control recognition are as follows: the photoelectric eyes have a decay in lifespan; the photoelectric eyes can recognize white or light colors close to white, and misrecognize when the color deepens; the photoelectric eyes are easily interfered by strong light; the photoelectric eyes are interfered by the reflection or shielding of stains and foreign objects (such as paper scraps, foam scraps, hair) on the mahjong cards; the acrylic protective layer on the surface of the photoelectric eyes will age and wear over time, becoming blurred on the surface, which also affects its recognition accuracy; when the card stacking motor (synchronous motor) of the mahjong machine catches the incoming cards, there is a small probability of occasional small flips, manifested as the receiving seat that should continue to sink suddenly lift up, and the probability that the photoelectric eye recognizes it as two incoming cards at this time is very high.
[0004] Therefore, a card receiving control mechanism of a mahjong machine that replaces photoelectric control with magnetic control is provided to solve the above problems. Content of the Utility Model
[0005] A card receiving control mechanism of a mahjong machine that replaces photoelectric control with magnetic control proposed by the utility model aims to solve the problem of easy errors in photoelectric control recognition existing in the prior art.

The incoming card pendulum 33 is connected to the sliding rod 3 through the connecting plate 31, and the incoming card pendulum 33 is driven to rotate by the rotation of the sliding rod 3 in the sliding groove.
[0026] In one embodiment, two mounting holes 111 are provided on the base plate 11; the C-shaped block includes a first block 14 and a second block 15; the two mounting holes 111 are located on the base plate 11 and close to one side of the two support plates 12; the distance between the first block 14 and the second block 15 corresponds to the height of the incoming card magnetic control 4; the card blocking seat 1 is provided with a movable hole 13 and is located on the left side of the C-shaped block, the two second fixed blocks 21 are located on both sides above the movable hole 13, and the two first fixed blocks 2 are located on both sides of the two second fixed blocks 21.

A limiting convex column 34 is arranged on the upper edge of the incoming card pendulum 33. When the inertia of the back swing of the incoming card pendulum 33 is large, its position is limited to the maximum back swing position. The front end arc tip of the incoming card pendulum 33 is flush with the front facade of the card blocking seat 1. A counterweight through hole 32 is arranged on the lower end of the incoming card pendulum 33, and a steel shaft counterweight can be added to the left end according to actual conditions. There is a cylindrical strong magnetic hole on the right side to assemble the strong magnetic back When the magnetron Hall sensor is swung to the corresponding position, the magnetron receives the signal to sense the incoming cards and feed it back to the PC mainboard to control the mahjong machine to complete actions such as stacking cards, counting, and pushing codes. The simple structure realizes the completion of the incoming card recognition action, avoiding the six disadvantages of the photoeye, especially the slight reversal of the motor to lift the card receiving seat will not cause the magnet of the incoming card pendulum 33 to retreat to the position of the magnetically controlled Hall sensor, nor will it cause card viewing recognition errors, thereby causing final counting errors of the mainboard and other sensors. That is, the error probability of the existing mahjong machine induction control system using the photoeye to recognize the incoming cards is almost eliminated.
