In FIG. 1, the card shooter device 4 is manually pulled out one by one from the card storage part 5 ).

[0010] A card guide unit 7 that guides the card 1 toward the game table 6, and a card storage unit 5 When the card 1 is manually drawn from the by a casino dealer or the like, a code reading unit 8 that reads a code 2 representing the number (quantity, rank) of the card 1 from the card 1, and based on the number of cards 1 sequentially read by the code reading unit 8 A win / loss determination unit 10 that determines the win / loss of the card game, and an output unit 11 that outputs the determination result of the win / loss determination unit 10 are included. The card guide unit 7 is provided with card access restriction units 30, 40 (described later) that restrict the access of the card 1 from the card storage unit 5 .

[0011] Next, the details of the code reading unit 8 that reads the code 2 representing the number (quantity, rank) of the card 1 from the card 1 when the card 1 is manually drawn from the card storage unit 5 will be described with reference to FIG. 3 . FIG. 3 is a plan view of the main part of the card shooter device 4. In the figure, the code reading unit 8 is provided in the card guide unit 7 that guides the card 1 taken out one by one manually from the opening 13 in front of the card storage unit 5 onto the game table 6. The card guide unit 7 is an inclined surface, and card guides 14 that also serve as sensor covers are attached to both side edges . Further, each of the two card guides 14 is detachably attached with screws or the like (not shown) . When the card guide 14 is removed, the sensor group 15 of the code reading unit 8 is exposed . The sensor group 15 consists of four sensors, two ultraviolet reaction sensors (UV sensors) 20 , 21, and object detection sensors 22, 23 .

[0012] The object detection sensors 22, 23 are fiber optic sensors that detect the presence or absence of the card 1 and can detect the movement of the card 1. The object detection sensor 22 is located in the card guide unit 7​ The other object detection sensor 23 is located upstream along the flow direction of card 1, and below It is located on the flow side. As shown in the figure, both object detection sensors 22 and 23 are UV sensor 2 They are located upstream and downstream of 0 and 21. UV sensors 20 and 21 detect ultraviolet light. It is equipped with an LED that emits light (ultraviolet LED) and a detector. Card 1 emits light when exposed to ultraviolet light. The mark M in code 2 is printed using UV-emitting ink, and UV light (black A light (black light) is shone onto card 1, and the reflected light from mark M of code 2 on card 1 is detected by the detector. It is detected. UV sensors 20 and 21 are transmitted via cable to the control device 12 of the code reading unit 8. It is connected to the following. The code reading unit 8 reads the output signals of the UV sensors 20 and 21. The combination of Mark M is determined, and the number (rank) corresponding to each code 2 is determined.

[0013] The code reading unit 8 reads the detection signals from the object detection sensors 22 and 23, and then the UV sensor 2 The start and end of reading 0 and 21 are controlled by the control device 12. Furthermore, the control device 12... The object detection sensors 22 and 23 also detect whether or not card 1 has passed through the card guide section 7 successfully. The determination is made based on the detection signal. As shown in Figure 2, the rank (number) and suit of the card The square mark M, representing (hearts, spades, etc.), is arranged in two columns and four rows along the edge of card 1. The UV sensors 20 and 21 output an ON signal when they detect mark M. The 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 reads the two marks detected by the two UV sensors 20 and 21. The code is identified based on relative differences in the mark M, and the number (rank) and type of the corresponding card 1 are determined. Identify the suit.

[0014] Figure 5 shows the relationship between code 2 and the ON signal output of the two UV sensors 20 and 21. Based on the comparison results of the relative changes in the ON signal outputs of sensors 20 and 21, a predetermined mark M The combinations can be identified. As a result, there are four possible combinations of the two rows of marks M. If you print this in four columns, you can create 256 different codes (4 types to the power of 4). (Playing cards) Each of the 52 types of cards is assigned to one of the 256 types of codes, and this is used as a reference table. The code is stored in memory or program, and the code reading unit 8 identifies each code 2. Then, from a predetermined reference table (not shown), determine the number (rank) and type (suit) of card 1. The configuration is designed to identify the code. Furthermore, the 256 codes can be freely combined with the 52 cards. Because they can be matched and stored in a comparison table, the combinations can be made complex, and The combination of 256 codes and 52 cards can be changed depending on the time and location. The code is printed with a paint that becomes visible when exposed to ultraviolet light, and indicates the type of card and It is desirable that it be printed in a position that does not overlap with index 102.

[0015] Next, the configuration of the control device 12 will be described. This control device 12, the code reading unit 8, and the The loss determination unit 10 etc. is a computer device that, for example, automatically determines the outcome of a game. The control function (win / loss determination unit 10) involves incorporating a program for determining wins and losses into the computer. This is more advanced, and this program runs on the computer's processor. The reading unit 8 uses UV sensors 20 and 21 to sequentially retrieve data for the game table 6. The number of cards is obtained, and the number of cards obtained is sequentially stored in memory. At this time, The information of which player each card was dealt to is also stored. It is remembered in association with the player. In the game of baccarat, there is a player and a banker. The rank (number) of the cards dealt to each player is stored in memory, and both The ranks (numbers) of the cards dealt to the players are totaled, and according to the programmed rules, The winner will be determined. A draw will also be determined.

[0016] Next, regarding the card insertion / removal restriction unit 30 that restricts the insertion and removal of card 1 from the card storage unit 5... This will be explained with reference to Figure 4. In Figure 4(a), the card insertion / removal restriction section 30 is located in the card storage section 5 The cards 1, taken out one by one from the opening 13 at the front, are guided onto the game table 6. It is located in the card guide 14 of the card guide section 7. Card 1 passes through the slot 33 between the card guide section 7 and the guide cover of card guide 14. At that time, the locking member 34 presses against the card 1, preventing the card 1 from entering or leaving the slot 33. It has a structure that allows the locking member 34 to engage with the drive unit 35, such as an electromagnetic solenoid or piezoelectric element. Therefore, the position where card 1 is pressed (restriction position) and the passable position that allows card 1 to pass through. It moves as shown by arrow M so that it can take on two states: and . The drive unit 35 controls the Controlled by position 12, the locking member 34 is positioned to press against card 1 and to allow card 1 to pass through. It moves to two states: a passable position and a control device 12 for the baccarat game. The rules are pre-programmed and stored in memory.

[0017] Next, a modified example of the card insertion / removal restriction unit 30 will be explained with reference to Figure 4(b). In this case, the card insertion / removal restriction section 40 is such that card 1 is connected to the card guide section 7 and card guide 14. When passing through the slot 33 between the door cover, the locking member 36 protrudes into the slot 33. The locking member 36 is equipped with a structure that prevents the movement of card 1. The drive unit 37, such as an element, prevents the movement of card 1 from being set to a position (restriction position), and card 1 As shown by arrow M, it can take two states: a passable position that allows passage and a moving position that allows passage. The drive unit 37 is controlled by the control device 12 and presses the locking member 36 against the card 1. Move to one of two states: a position where it is to be moved, and a passable position where card 1 can pass through.

It has the function of doing so. The content that is controlled as unauthorized entry or exit of card 1 (programmed) The content includes at least the following 1) and 2):

[0019] 1) From the outside, through the opening 13 toward the card storage section 5 in the opposite direction to the direction of arrow S A function that prevents the insertion of card 1 into the slot. In this case, the insertion of card 1 for fraudulent purposes is when card 1 is inserted into card guide section 7 and card guide 1 It passes through slot 33 between 4, but based on the detection signals of object detection sensors 22 and 23 The control device 1 detects the movement of card 1 in the opposite direction to its normal movement (the opposite direction of arrow S in Figure 3), and According to program 2, the drive units 35 and 37 are locked in a position that presses or blocks card 1. Move members 34 and 36.

[0020] 2) Card reading unit (When card 1 is pulled out from card storage unit 5, the number on card 1 is read) In the code reading unit 8 which reads code 2 representing the rank from card 1, Based on the suit and rank information of the read card 1, the card is drawn from the card storage compartment 5. A function that prevents card 1 from being drawn when it is not available. In this case, the control device 12 is pre-programmed with the rules of the baccarat game as described above. In baccarat, the banker and player each draw two or more cards of the card 1. Whether or not depends on the total rank (number) of the two cards already dealt to the banker and the player. It is uniquely determined by the rule. Therefore, when you should not draw a third card, each If the dealer at the table tries to deal out card 1, it would be against the rules, so The movement of card 1 is restricted. Even if card 1 is drawn at a time and in a situation where it should not be drawn... Then, based on the detection signal from the object detection sensor 22, the movement of card 1 is detected. Then, according to the program of the control device 12, the drive units 35 and 37 press or block the card 1. The locking members 34 and 36 are moved to the position where they press or block the card 1. The locking members 34 and 36 move to a position that prevents further distribution of card 1 (as shown in Figure 4). (Location). In this way, the dealer can detect the withdrawal operation of card 1 which violates the rules. This prevents card 1 from being drawn, which is compared to locking the cards at the end of each game. Overall, the wear and tear on the device that restricts card insertion and removal is minimal.

[0021] When the card insertion / removal restriction unit 30 (40) is activated, this is indicated to the outside (a lamp lights up). An error signal output unit 50 is provided (which also emits an alarm sound), and the control device 12 The operation is controlled by this. [Industrial applicability]
