Upon receiving the ball supply instruction, the ball supply control device 23 gives a ball supply instruction to the game machine, and the game machine receiving this instruction outputs the ball. In the present embodiment, the ball output itself is performed by the game stand. However, a mechanism for outputting a ball to the ball lending machine 20 may be provided so that the ball is output from the ball lending machine 20.
[0022]
On the other hand, the amount data obtained by subtracting the purchase price etc. of the balls is sent to the card reader / writer 21 where it is recorded on the card 10, where the amount corresponding to the subtracted amount data is once. When the amount is less than or equal to the amount necessary for lending the ball, the control device 22 gives the ball supply control device 23 an instruction to output the balance of the balls recorded on the card 10 and causes the balance of balls to be output. . At the same time, the amount indicated in the amount data of the card 10 is set to 0, and an instruction to store the card 10 in the card storage device 1 is given to the card reader / writer 21.
[0023]
Upon receiving this instruction, the card reader / writer 21 sets the amount indicated in the amount data of the card 10 to 0 and stores the card 10 in the card storage device 1. The card 10 is stored by freely dropping the card 10 in a direction (A direction shown in FIGS. 1 and 5) from the upper part of the card storage device 1 to the lower side, and the dropped card 10 is stored in the card storage device 1. It is stored in the internal card holding part 1a. Here, when the card 10 dropped in the A direction reaches the inclined plate 1aa of the card holding portion 1a, the card 10 falls down along the inclined plate 1aa and is stacked on the inclined plate 1aa. Thereby, the card | curd 10 will be piled up and stored diagonally with respect to the bottom face of the card holding part 1a. As shown in FIG. 4, the card 10 is stacked on the inclined plate 1aa, and one side thereof is held by the vertical plate 1ab, and another side is held by the side plate 1ac and stored. Here, the stored card 10 is held only by the three planes of the inclined plate 1aa, the vertical plate 1ab, and the side plate 1ac, and is not held from the surface on the card outlet 1ae side facing the side plate 1ac. Therefore, a stopper 1d is used as means for holding the card 10 from the surface of the card ejection port 1ae and preventing the card 10 from popping out from the card ejection port 1ae.
[0024]
As shown in FIG. 1 and FIG. 2B, the stopper 1d has a plate shape, and the side surface of the card 10 accommodated in the card holding portion 1a is placed on the card outlet 1ae by the flat portion of the plate shape.

The front panel 1b is locked by a panel key 1c, and the panel key 1c can be unlocked by inserting a key into the panel key 1c or by performing a remote operation described later. When the panel key 1c is unlocked and the front panel 1b is opened in the direction E shown in FIG. 8 (a), the card holding unit 1a is then pulled out.
[0027]
The card holder 1a is pulled out of the card storage device 1 from the inside of the card storage device 1 in the direction (G direction) toward the front panel 1b. When a force in the G direction is applied to the card holding portion 1a, the card holding portion 1a presses the stopper 1d from the inner side toward the outer side by the side surface on the card outlet 1ae side. The stopper 1d pressurized by the card holding part 1a performs the rotational movement (F direction) around the rotational axis described above, and the plane part rotates and moves to a position perpendicular to the side surface on the card ejection port 1ae side. . As a result, the stopper 1d holding the card ejection opening 1ae side is stowed into the inner side surface of the card storage device 1, and a force in the G direction is further applied to the card holding unit 1a, whereby the card holding unit 1a The card outlet 1ae is drawn out of the card storage device 1 (FIG. 8B). 9 and 10 are detailed perspective views of the card storage device 1 showing a process in which the card holding portion 1a is pulled out of the card storage device 1. FIG. Here, FIG. 9 shows a state in which the stopper 1d holds the side surface of the card 10 accommodated in the card holding portion 1a from the card outlet 1ae side, and the front panel 1b is opened, and FIG. A state in which the holding unit 1a is pulled out of the card storage device 1 is shown.
[0028]
Next, a presence / absence sensor light emitting unit 1e for determining whether or not the card 10 is stored, a presence / absence sensor light receiving unit 1f, an upper limit sensor light emitting unit 1g for determining whether or not the number of stored cards 10 has reached the upper limit, and an upper limit sensor The operation of the light receiving unit 1h will be described. FIG. 11 and FIG. 12 are diagrams showing operations of the presence / absence sensor light emitting unit 1e, the presence / absence sensor light receiving unit 1f, the upper limit sensor light emitting unit 1g, and the upper limit sensor light receiving unit 1h.
[0029]
As shown in FIGS. 11 and 12, the presence / absence sensor light-emitting unit 1 e is inside the bottom surface of the card storage device 1, and the presence / absence sensor light-receiving unit 1 f and the upper limit sensor light-receiving unit 1 h are inside the side surface of the card storage device 1. 1 g is arranged inside the upper surface of the card storage device 1. Thereby, from the presence sensor light emission part 1e and the upper limit sensor light emission part 1g, it is substantially parallel to one plane which has one edge in the horizontal direction of the card | curd 10 accommodated in the card holding | maintenance part 1a, and the normal line with respect to a bottom face, and Detection light is output in a direction that obliquely crosses the stacking direction of the stored cards 10. Here, in the case of the present embodiment, the vertical plate 1ab of the card holding unit 1a is substantially parallel to one plane having one edge in the horizontal direction of the card 10 stored in the card holding unit 1a and the normal to the bottom surface. And substantially parallel to each other.
[0030]
These sensors are controlled by the control device 22, and when the control device 22 instructs the card reader / writer 21 to store the card 10, an unlocking instruction is given to the panel key 1c by a remote operation described later. In this case, the detection light output from the presence / absence sensor light emitting unit 1e is detected by the presence / absence sensor light receiving unit 1f, and the detection light output from the upper limit sensor light emitting unit 1g is detected by the upper limit sensor light receiving unit 1h. In this embodiment, the output of the detection light from the presence / absence sensor light emitting unit 1e and the upper limit sensor light emitting unit 1g is generated when the control device 22 instructs the card reader / writer 21 to store the card 10 or by remote operation. When the unlocking instruction is given to the panel key 1c, it is performed for a certain period, but the detection light may be output at other timing.
[0031]
First, a determination method for determining whether or not the card 10 is stored will be described with reference to FIG.
As shown in FIG. 11A, when the card 10 is not stored in the card holding unit 1a, the detection light output from the presence / absence sensor light emitting unit 1e passes through the detection light passing unit 1ad of the card holding unit 1a. And reaches the presence / absence sensor light-receiving portion 1f. Then, the detection light reaching the presence / absence sensor light receiving portion 1f is detected by the presence / absence sensor light receiving portion 1f. On the other hand, as shown in FIG. 11B, when the card 10 is stored in the card holding unit 1a, the detection light output from the presence / absence sensor light emitting unit 1e is transmitted by the card 10 stored in the card holding unit 1a. The detection light does not reach the presence / absence sensor light-receiving portion 1f. In this case, the detection light is not detected by the presence sensor light receiver 1f.
[0032]
As described above , when the card 10 is not stored in the card holding unit 1a, the presence / absence sensor light receiving unit 1f detects the detection light, and when the card 10 is stored, the presence / absence sensor light reception unit 1f detects the detection light. Therefore, it is possible to determine whether the card 10 is stored in the card holding unit 1a by determining whether the presence / absence sensor light receiving unit 1f detects the detection light. Become.
[0033]
Next, a determination method for determining whether or not the number of stored cards 10 has reached the upper limit will be described with reference to FIG.
FIG. 12A shows a case where the stored card 10 has not reached the upper limit of the storage number. In this case, the detection light output from the upper limit sensor light receiving unit 1g reaches the upper limit sensor light receiving unit 1h, and the detection light reaching the upper limit sensor light receiving unit 1h is detected by the upper limit sensor light receiving unit 1h. On the other hand, (b) of FIG. 12 shows a case where the card 10 has reached the upper limit of the storage number. In this case, the detection light output from the upper limit sensor light emitting unit 1g is blocked by the card 10, and this detection light. Does not reach the upper limit sensor light receiving unit 1h. In this case, the detection light is not detected by the upper limit sensor light receiving unit 1h.
[0034]
As described above , when the stored card 10 has not reached the upper limit of the storage number, the upper limit sensor light receiving unit 1h detects the detection light, and when the card 10 has reached the upper limit of the storage number, the upper limit sensor light receiving unit. Since 1h does not detect the detection light, it is determined whether or not the stored card 10 has reached the upper limit of the storage number by determining whether or not the upper limit sensor light receiving unit 1h detects the detection light. It becomes possible to do.
[0035]
Next, the above-described determination procedure will be described with reference to FIG.
When the control device 22 instructs the card reader / writer 21 to store the card 10, or when an unlocking instruction is given to the panel key 1c by remote operation to be described later, the control device 22 detects the upper limit sensor light emitting unit 1g and The presence / absence sensor light emitting unit 1e is instructed to output detection light for a certain period. Upon receiving this instruction, the upper limit sensor light emitting unit 1 g and the presence sensor light emitting unit 1 e emit detection light, and the presence sensor light receiving unit 1 f and the upper limit sensor light receiving unit 1 h send detection results of these detection lights to the control device 22. Based on the detection results received from the presence / absence sensor light-receiving unit 1f and the upper limit sensor light-receiving unit 1h, the control device 22 determines the presence / absence and storage state of the card 10 according to the above-described determination method, and performs various types according to the determination results. Process.
[0036]
Next, the collective unlocking operation of the plurality of card storage devices 1 performed by remote operation will be described.
FIG. 13 is a perspective view showing an external configuration of the unlocking device 30. The unlocking device 30 has a keyhole 30a, an unlocking lamp 30b, and a withdrawal lamp 30c.

FIG. 14 is a perspective view showing an arrangement example of a plurality of ball lending machines 20 connected to the unlocking device 30 and a gaming table 40 corresponding to these ball lending machines 20.
[0037]
When unlocking the panel key 1c of each of the plurality of card collecting devices 1 using the unlocking device 30, a store clerk or the like who unlocks first inserts the key into the key hole 30a of the unlocking device 30 and inserts the key. While pressing the key, turn it to the position of the unlocking lamp 30b. Thereby, the unlocking lamp 30b is turned on, and an unlocking signal is sent from the unlocking device 30 to the control device 22 of each ball lending machine 20. Receiving the unlock signal, each control device 22 determines whether or not the card 10 is stored in the card storage device 1 by the above-described method, and controls itself when determining that the card 10 is stored. The panel key 1c is unlocked. If it is determined that the card 10 is not stored, the panel key 1c is not unlocked. When the unlocking of the panel key 1c of each card collecting device 1 is completed in this way, the key is then turned to the position of the pulling lamp 30c, the key is pulled out, and the panel key 1c is unlocked collectively by the unlocking device 30.
