Further, the card shooter device 2 includes a card guide unit 7 that guides the cards 1 manually drawn out from the card storage unit 2C one by one toward the game table, and a card 1 from the card storage unit 2C by a casino dealer or the like. Win / loss of the card game based on the code reading unit 8 that reads the code C representing the number (number, rank) of the card 1 when manually withdrawn, and the number (rank) of the cards 1 that are sequentially read by the code reading unit 8. The winning / losing determination unit 10 for determining the above is provided, and the output means 11 for outputting the determination result of the winning / losing determination unit 10 is provided.

FIG. 4 shows the cards 1 constituting the shuffle playing card 1s. On the card 1 used for a table game such as a baccarat, a number is coded and printed as a mark M with UV ink or the like which is normally invisible. The code C composed of the mark M is provided point-symmetrically on the upper side and the lower side of the card 1. It is desirable that the code C is printed with a paint that is visualized by receiving ultraviolet light, and is printed at a position that does not overlap with the card type notation or index.

Next, the details of the code reading unit 8 that reads the code C representing the number (number, rank) of the card 1 from the card 1 when the card 1 is manually withdrawn from the card accommodating unit 2C will be described with reference to FIG. FIG. 5 is a plan view of a main part of the card shooter device 2. In the figure, the code reading unit 8 is provided in the card guide unit 7 that guides the cards 1 manually taken out one by one from the opening 13 in front of the card storage unit 2C onto the game table. The card guide portion 7 is an inclined surface, and a card guide cover 14 that also serves as a sensor cover is attached to the edge portions on both sides. Further, each of the two card guide covers 14 can be attached and detached with screws or the like (not shown). When the card guide cover 14 is removed, the sensor group 15 of the code reading unit 8 is exposed. The sensor group 15 is composed of four sensors, two ultraviolet reaction sensors (UV sensors) 20, 21 and an object detection sensor 22, 23. A UV reaction sensor 24 for reading the set code SC is provided near the two UV reaction sensors (UV sensors) 20 and 21, and has the same function as the UV reaction sensors 20 and 21 and has the same function as the set code SC. An output signal is output depending on the presence or absence of.

The object detection sensors 22 and 23 are optical fiber type sensors that detect the presence / absence of the card 1 and can detect the movement of the card 1. The object detection sensor 22 is located on the upstream side of the card guide unit 7 along the flow direction of the card 1 (arrow F), and the other object detection sensor 23 is located on the downstream side. As shown in the figure, both object detection sensors 22 and 23 are provided on the upstream side and the downstream side with the UV sensors 20 and 21 interposed therebetween. The UV sensors 20 and 21 include an LED (ultraviolet LED) that emits ultraviolet rays and a detector. The mark M is printed on the card 1 with ultraviolet light emitting ink that develops color when exposed to ultraviolet rays, the card 1 is irradiated with ultraviolet rays (black light), and the reflected light of the mark M of the code C of the card 1 is detected by the detector. Detected. The UV sensors 20 and 21 are connected to the control unit 12 of the code reading unit 8 via a cable. In the code reading unit 8, the combination of the marks M is determined from the output signals of the detectors of the UV sensors 20 and 21, and the number (rank) corresponding to each code C is determined.

The code reading unit 8 is controlled by the control unit 12 to start and stop reading the UV sensors 20 and 21 based on the detection signals of the object detection sensors 22 and 23. Further, the control unit 12 determines whether or not the card 1 has normally passed through the card guide unit 7 based on the detection signals of the object detection sensors 22 and 23. As shown in FIG. 4, square marks M representing card ranks (numbers) and suits (hearts, spades, etc.) are arranged on the edge of card 1 in two columns and four rows. When the UV sensors 20 and 21 detect the mark M, they output an on signal. The code reading unit 8 determines the relative relationship between the two signals input from the two UV sensors 20 and 21. As a result, the code reading unit 8 identifies the code based on the relative difference between the two marks M detected by the two UV sensors 20 and 21, and the number (rank) and type (suit) of the corresponding card 1. To identify.

FIG. 6 shows the relationship between the code C and the outputs of the on signals of the two UV sensors 20 and 21. A predetermined combination of marks M can be specified based on the comparison result of the relative change of the output of the on signal of the UV sensors 20 and 21. As a result, 4 types of marks M in the upper and lower 2 rows are combined, and if this is printed in 4 rows, 256 types of codes can be configured by 4 types of 4th power. 52 kinds of cards of playing cards are assigned to any of 256 kinds of codes, and this is stored in a memory or a program as a comparison table, and the code reading unit 8 identifies each code C and determines in advance. The number (rank) and type (suit) of card 1 are specified from the comparison table (not shown). In addition, 256 types of codes can be associated with 52 types of cards in any combination and stored in a comparison table, so that the combination can be complicated, and 256 types of code C and 52 types of cards can be stored depending on the time and place. You can change the combination of suits and ranks. It is desirable that the code C is printed with a paint that is visualized by receiving ultraviolet light, and is printed at a position that does not overlap with the card type notation or index.

Next, the control unit 12 will be described in detail. The control unit 12 is a computer device, and includes, for example, a win / loss determination unit 10 that automatically determines the outcome of a game, and these processing functions (in the control unit 12) include a program for determining the outcome in a computer. It has been realized and this program is executed on the processor of the computer. Further, the shuffle card ID that can individually identify the shuffle playing card 1s from the bar code 3 read by the bar code reader 100 is stored in the reading memory 12M. The control unit 12 reads the barcode 3 by the barcode reader 100, stores the shuffle card ID that can be individually identified, and the shuffle playing card 1s as a card set currently used in the game in association with the shuffle card ID. Is specified and memorized together with the current time. The control unit 12 further associates the following specific occurrences that occurred while using the shuffle playing card 1s specified by the shuffle card ID in the game table with the current time for each specific occurrence in the memory 12M. Remember. In addition, the occurrence of a specific occurrence is the number of the shuffle playing card 1s currently in the card shooter device, or an individual game using the shuffle playing card 1s (whether the player wins for each individual game). , The winning or losing judgment of whether the bunker wins or not is made, and the next individual game starts after the bet chip is settled).

Items of specific occurrence items to be stored in association with the shuffle card ID include at least one of the following items.
(1) There was an error in reading the specified shuffle playing card in the card reading unit 8.
(2) The game is terminated by the operation of the end button 53 that ends the use of the shuffle playing card 1s currently in the card shooter device 2, or the game is terminated by the appearance of the cut card 1c from the existing shuffle playing card 1s. (3) An attempt was made to withdraw a card when it should not have been withdrawn according to the rules of the card game.
(4) The card was about to move or be inserted in the opening 13 in the direction opposite to the withdrawal direction.
(5) An abnormal operation preset in advance so that the card shooter device 2 determines that it is abnormal has occurred.
It has a configuration that includes at least one of them.

It should be noted that the reading error of (1) is caused by the code reading unit 8 reading the two marks M of the card 1, the code being not a predetermined code and not being able to be specified from a comparison table or the like, or the number of cards 1 corresponding to the code ( It means that the rank) and type (suit) could not be specified. (2) When the use of the shuffle playing card 1s currently in the card shooter device 2 is terminated, the end button 53 is pressed. By this operation, the end of the game is registered in the card shooter device 2. If a cut card 1c appears from the shuffle playing card 1s currently existing in the card shooter device 2, the game ends after or several games after the game in which the cut card 1c appears, and the remaining shuffle playing card 1s is a game thereafter. Not used for. The fact that the card was to be withdrawn when the card should not be withdrawn according to the rules of the card game in (3) will be described later. The fact that the card was about to be inserted in the opposite direction from the opening 13 in (4) means that the object detection sensors 22 and 23 move the card in the direction opposite to the movement of the card 1 in the state (arrow F). It detects fraudulent activity such as being inserted. It is assumed that the object detection sensors 22 and 23 detect the movement of the card 1 in the direction opposite to the arrow F. The abnormal situation stored in advance by the card shooter device 2 shown in (5) so as to determine that it is abnormal means, for example, when the card 1 abnormally stagnates on the object detection sensors 22 and 23 for a predetermined time, and the memory. It is input and stored as a program in advance in 12M.

The memory 12M stores that a security item has occurred in association with the shuffle card ID for each shuffle card ID read from the barcode 3, and also stores the time when the security item has occurred when the security item is stored. Therefore, it is equipped with a clock 12t that knows the current time. Further, the transmission device 300 for transmitting the occurrence of a security item to the outside together with the shuffle card ID is further provided. The management department or pit of the casino is notified via the external transmission device 300 that a security item has occurred in association with the shuffle card ID for each shuffle card ID and the time when the security item has occurred. In the management department of the casino, these transmitted items are stored and registered in the database 400 in association with the shuffle card ID. Further, the occurrence of the security item is displayed by the lamp 51 and the liquid crystal display unit 52 to notify the dealer or the like.

Next, a modified example in which the input means 200 is provided instead of the bar code reader 100 capable of specifying the shuffle card ID will be described. Instead of reading the barcode 3 with the barcode reader 100 and identifying the shuffle card ID currently in use, another device installed in the game table (for example, a card 1 disposal device or a discard card confirmation device) is used. Even if a bar code reader is provided, the shuffle card ID to be used is acquired by the bar code reader, and communication 201 is performed with these devices, so that the shuffle card ID is input to the card shooter device 2. good. In this case, another device equipped with a barcode reader becomes an input device capable of specifying the shuffle card ID.

Next, the card entry / exit restricting means 30 for restricting the entry / exit of the card 1 from the card storage section 2C will be described with reference to FIG. 7. The card guide unit 7 is provided with a card entry / exit restricting means 30 for restricting the entry / exit of the card 1 from the card storage section 2C. In FIG. 7A, the card entry / exit restricting means 30 is provided on the card guide cover 14 of the card guide unit 7 that guides the cards 1 taken out one by one from the opening 13 in front of the card storage unit 2C onto the game table. Has been done. In the card entry / exit limiting means 30, when the card 1 passes through the slot 33 between the card guide portion 7 and the card guide cover 14, the lock member 34 presses the card 1 to allow the card 1 to enter / exit in the slot 33. It has a structure to prevent it. The lock member 34 can take two states, a position for pressing the card 1 (restricted position) and a passable position for allowing the card 1 to pass by a drive unit 35 such as an electromagnetic solenoid or a piezoelectric element. Move as shown by the arrow Mo. The drive unit 35 is controlled by the control unit 12 and moves the lock member 34 into two states, a position where the card 1 is pressed and a passable position where the card 1 can pass. The rules of the baccarat game are pre-programmed and stored in the control unit 12.

Next, a modified example of the card entry / exit restricting means 30 will be described with reference to FIG. 7 (b). In the modified example, the card entry / exit restricting means 40 has a lock member 36 protruding into the slot 33 to prevent the card 1 from moving when the card 1 passes through the slot 33 between the card guide portion 7 and the card guide cover 14. It has a structure to do. The lock member 36 can take two states, a position (restricted position) for blocking the movement of the card 1 and a passable position for allowing the card 1 to pass by a drive unit 37 such as an electromagnetic solenoid or a piezoelectric element. It moves as shown by the arrow Mo. The drive unit 37 is controlled by the control unit 12 and moves the lock member 36 into two states, a position where the card 1 is pressed and a passable position where the card 1 can pass.

By controlling the drive units 35 and 37 so as to prevent the card 1 from entering and exiting illegally by the program of the control unit 12, the card entry / exit limiting means 30 (40) is made to function. The card entry / exit restricting means 30 (40) is provided with object detection sensors 22 and 23 as sensors for detecting the movement of the card 1, and the movement of the card 1 is detected by these sensors to limit the movement of the card 1.

1) A function of preventing the insertion of the card 1 which is inserted or moved from the outside toward the card storage portion 2c through the opening 13 in the direction opposite to the direction of the arrow F. In this case, when the card 1 is inserted for fraudulent purposes, the card 1 passes through the slot 33 between the card guide unit 7 and the card guide cover 14, but the card 1 is based on the detection signals of the object detection sensors 22 and 23. The lock members 34, 36 are placed at positions where the drive units 35, 37 press or prevent the card 1 by the program of the control unit 12 by detecting the movement in the direction opposite to the normal direction (the direction opposite to the arrow F in FIG. 3). Moving. In this case, the control unit 12 determines that the card is about to be inserted or moved in the opposite direction from the opening (4) of the security item.

2) The card 1 read by the card reading unit (meaning the code reading unit 8 that reads the code C representing the number (number, rank) of the card 1 from the card 1 when the card 1 is withdrawn from the card accommodating unit 5). A function to prevent the card 1 from being pulled when it should not be pulled out from the card housing 2c based on the information of the suit trunk of. In this case, the rules of the baccarat game are programmed in the control unit 12 in advance as described above. In a baccarat game, whether or not a bunker and a player should draw two or more cards 1 each is uniquely determined by the total rank (number) of the two cards already distributed by the bunker and the player. Therefore, if the dealer at each table tries to distribute the card 1 when the third card should not be drawn, the rule is violated and the movement of the card 1 is restricted. When the card 1 is to be pulled at a timing or situation where it should not be pulled, the movement of the card 1 is detected based on the detection signal of the card 1 of the object detection sensor 22, and the drive unit 35, by the program of the control unit 12. The lock members 34 and 36 are moved to a position where 37 presses or blocks the card 1. As a result, the lock members 34 and 36 move to positions where the card 1 is pressed or blocked, and further blocking the card 1 from being distributed (position shown in FIG. 4). In this case, the control unit 12 determines that the card is to be withdrawn when the card should not be withdrawn according to the rule of the security item (3) card game. This corresponds to (3) of the item (3) of the specific occurrence item to be stored in association with the shuffle card ID described above. That is, in the above-mentioned item (3), it is registered in the control unit 12 that the card is to be withdrawn when the card should not be withdrawn according to the rules of the card game.

When an event corresponding to the above specific occurrence item (security item) occurs, the security item is associated with the shuffle card ID for each shuffle card ID of each shuffle playing card 1s in the management department or pit of the casino via the external transmission device 300. Is notified and the time when the security item occurs is notified, and is connected to and stored in the database 400. Further, the occurrence of the security item is displayed by the lamp 51 and the liquid crystal display unit 52 to notify the dealer or the like.
