FIG. 1 is a block diagram showing the entire card shooter device used in the table game system of the present embodiment. FIG. 2 shows a card 1 used in the table game system of the present embodiment. The card 1 used in a table game such as baccarat is provided with a code 2 composed of a normally invisible mark M point-symmetrically on the upper side and the lower side of the card 1. The number (number, rank) of the card 1 is coded by this code 2. Further, the card 1 is provided with a authenticity determination code 3 in which information indicating the authenticity of the card is coded and arranged by printing or the like in a normally invisible state (for example, ultraviolet reaction ink).

In FIG. 1, in the card shooter device 4, the card guide unit 7 that guides the cards 1 manually drawn out from the card storage unit 5 one by one toward the game table 6 and the card 1 from the card storage unit 5 are casinos. Based on the code reading unit 8 that reads the code 2 representing the number (number, rank) of the card 1 from the card 1 when manually withdrawn by the dealer, etc., and the number of cards 1 that are sequentially read by the code reading unit 8. It includes a win / loss determination unit 10 that determines the outcome of a card game, and an output unit 11 that outputs a determination result of the win / loss determination unit 10. The card guide unit 7 is provided with card entry / exit restriction units 30 and 40 (described later) that restrict the entry / exit of the card 1 from the card storage unit 5.

Next, the details of the code reading unit 8 that reads the code 2 representing the number (number, rank) of the card 1 from the card 1 when the card 1 is manually withdrawn from the card accommodating unit 5 will be described with reference to FIG. FIG. 3 is a plan view of a 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 cards 1 manually taken out one by one from the opening 13 in front of the card storage unit 5 onto the game table 6. The card guide portion 7 has an inclined surface, and card guides 14 that also serve as sensor covers are attached to the edges on both sides. Further, each of the two card guides 14 can be attached and detached 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 is composed of four sensors, two ultraviolet reaction sensors (UV sensors) 20, 21 and an object detection sensor 22, 23.

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, 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 of code 2 is printed on the card 1 with ultraviolet light emitting ink that develops color when exposed to ultraviolet rays, and the card 1 is irradiated with ultraviolet rays (black light) to reflect the mark M of code 2 of the card 1. Light is detected by the detector. The UV sensors 20 and 21 are the control device 12 of the code reading unit 8 via a cable.
It is connected to the. 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 2 is determined.

The code reading unit 8 is controlled by the control device 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 device 12 also 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. 2, square marks M representing the rank (number) and suit (heart, spade, etc.) of the card are arranged in two columns and four rows on the edge of the card 1. 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 cards 1. To identify.

The relationship between the code 2 and the output of the on signal of the two UV sensors 20 and 21 is shown in FIG. 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, four types of marks M in the upper and lower two rows are combined, and when this is printed in four rows, 256 types of codes can be configured by the fourth power of the four types. 52 types of playing cards are assigned to each of the 256 types 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 2 to determine 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 depending on the time and place, 256 types of codes and 52 types of cards can be combined. Can be changed. It is desirable that the code 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 102.

Next, the configuration of the control device 12 will be described. The control device 12, the code reading unit 8, the win / loss determination unit 10, and the like are computer devices. For example, a processing function (win / loss determination unit 10) that automatically determines the outcome of a game puts a program for determining win / loss on a computer. It is realized by incorporating it, and this program is executed by the processor of the computer. The code reading unit 8 uses the UV sensors 20 and 21 to acquire the number of cards sequentially taken out to the game table 6, and the number of the acquired cards is sequentially stored in the memory. At this time, information on which player each card 1 is dealt with is also stored. The number of cards is stored in association with the player to which it is distributed. In a baccarat game, there are players and bunkers. The rank (number) of cards dealt to each player is stored in memory, the ranks (number) of cards dealt to both players are totaled, and which one wins is determined from the programmed rules. A draw is also determined.

Next, the card entry / exit restriction section 30 that restricts the entry / exit of the card 1 from the card storage section 5 will be described with reference to FIG. In FIG. 4A, the card entry / exit restriction unit 30 is provided on the card guide 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 5 onto the game table 6. Has been done. In the card entry / exit restriction section 30, when the card 1 passes through the slot 33 between the card guide section 7 and the guide cover of the card guide 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. 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. It moves as shown by the arrow M. The drive unit 35 is controlled by the control device 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 be passed. The control device 12 pre-programs and stores the rules of the baccarat game.

Next, a modified example of the card entry / exit restriction unit 30 will be described with reference to FIG. 4 (b). In the modified example, when the card 1 passes through the slot 33 between the card guide unit 7 and the card guide 14 guide cover, the lock member 36 protrudes into the slot 33 to move the card 1. It has a blocking structure. The lock member 36 can take two states, a position where the movement of the card 1 is blocked (restricted position) and a passable position where the card 1 can be passed by a drive unit 37 such as an electromagnetic solenoid or a piezoelectric element. As shown by the arrow M, it moves. The drive unit 37 is controlled by the control device 12 and moves the lock member 36 to two states, a position where the card 1 is pressed and a passable position where the card 1 can be passed.

The card entry / exit restriction section 30 (40) is made to function by controlling the drive sections 35 and 37 so as to prevent the card 1 from entering / exiting illegally by the program of the control device 12. The card entry / exit restriction unit 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. Has the function of The contents (programmed contents) to be controlled as illegal entry / exit of the card 1 include at least the following 1) and 2).

1) A function of preventing the insertion of the card 1 which is inserted from the outside toward the card storage portion 5 through the opening 13 in the direction opposite to the direction of the arrow S.
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 14, but the card 1 is inserted based on the detection signals of the object detection sensors 22 and 23. The movement in the direction opposite to the normal direction (the direction opposite to the arrow S in FIG. 3) is detected, and the lock members 34 and 36 are moved to positions where the drive units 35 and 37 press or prevent the card 1 by the program of the control device 12. To do.

2) The card 1 read by the card reading unit (meaning the code reading unit 8 that reads the code 2 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 card 1 from being drawn when it should not be withdrawn from card storage 5 based on the suit and rank information of.
In this case, the control device 12 is pre-programmed with the rules of the baccarat game as described above. In the baccarat game, whether or not the bunker and the 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 deal card 1 when the third card should not be drawn, the rule is violated and the movement of 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 device 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 that press or prevent the card 1 and prevent further distribution of the card 1 (position shown in FIG. 4). In this way, the withdrawal operation of the card 1 that violates the dealer's rules is detected and the withdrawal of the card 1 is prevented. Less wear.

When the card entry / exit restriction unit 30 (40) is activated, an error signal output unit 50 is provided to notify the outside (the lamp lights up and an alarm sound is emitted), and the operation is controlled by the control device 12.

As described above, the card shooter device according to the present invention has an effect of being able to prevent fraudulent acts such as illegally inserting a card into the card shooter device or illegally or inappropriately distributing a card on the spot. It is useful for card games in casinos and the like.
