Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention attaches several coin-operated gaming machines such as pachislot machines and provides a coin circulation mechanism.GameRegarding machine unit islands.
[0002]
[Prior art]
  In a conventional island where a plurality of pachislot machines are installed and a mechanism for supplying coins to these pachislot machines and coin lending machines is provided, even if the number of islands is the same, depending on the request of the amusement store, The number of devices to be replenished is different. For example, there are cases where the same number of coin lending machines are installed in pairs with pachislot machines, and there are cases where one coin lending machine is installed between two pachislot machines. However, since the number of coin lending machines is different, the number of devices to be replenished is different. In addition, there are cases where the pachislo machine is installed on both sides and the case where it is installed on one side. In this case as well, the number of devices to be replenished is different.
  For this reason, in the conventional gaming machine installation island, the structure of the coin transport device, the number of coin introduction devices that take coins into the supply target device, and the control program of the control device that controls them differ according to the request of the game store. .
[0003]
[Problems to be solved by the invention]
  However, the control becomes complicated if the number and the mounting position of the coin introducing devices are varied depending on the number of replenishment target devices and the opening / closing control is made different according to the position of each coin introducing device.
[0004]
  In addition, if the coin is transported by the transport rail and the position of the coin introducing device is set to the transport rail, the control is specialized for the position, and the design becomes complicated. And, when the coin rolls on the lifting rail due to its own weight, the conditions such as friction and dust are different, so the time to reach the coin introducing device is not always constant, The arrival time also changes due to an assembling error at the time of installation, and accurate opening / closing control of the coin introducing device is difficult.
[0005]
  In addition, when accurate opening / closing control is to be performed, there is a high possibility that a coin biting will occur in the coin introduction device if it happens to take a long time to flow down. When coin biting occurs, when new circulation is performed, for example, when replenishment from another coin introducing device is required, the bitten coins become an obstacle and the function stops.
[0006]
  The present invention has been made in view of the above circumstances, and its purpose is to control the coin introducing device in the same manner regardless of the specifications even if the replenishment target device is appropriately installed according to the request from the amusement store. It is intended to provide a unit island for gaming machines.

[0008]
DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
  FIG. 1 is a front view of a gaming machine unit island 2 (hereinafter simply referred to as “unit island 2”) with a pachislot gaming machine (hereinafter simply referred to as “pachislot machine 1”) 1 attached. FIG. It is a schematic front view of the unit island 2 of the state which has not been carried out.
[0009]
  The unit island 2 in this embodiment is a so-called double-sided island in which a total of four pachislot machines 1 are placed back-to-back on both sides of the island body 3, and the coin circulation mechanism 4 is provided inside the island body 3. A coin lending machine 5 that is shared by a player who plays a game with the left and right pachislot machines 1 is installed between the two pachislot machines 1 and 1 according to the demand of the game store.
[0010]
  The island body 3 is composed of a long metal material such as aluminum or iron in a substantially rectangular parallelepiped shape to form a frame 6. A plate-like table mounting member 7 is provided on the frame 6 below the center of the height. In addition to the horizontal installation, the base upper fastening member 9 is installed in the horizontal direction above the base mounting member 7 to form the left and right game machine installation vacant spaces 10 for one machine. The inter-coin lending machine 5 can be installed in the left and right center part of the empty part 10, and the panels 11 and 12 are stretched and closed on the front and back surfaces above and below the gaming machine installation empty part 10. In addition, the island body 3 has an installation space at the end of the island body so that a coin lending machine 5 can be installed for each pachislot machine 1 according to the demand of the amusement store. The open front of this installation space is closed with a decorative cover 13 '.
  As shown in FIG. 1, the side surface of the island body 3 may be covered with a closing plate member 13 or may be closed by a joint portion (not shown) provided on the side surface of the frame 6 in an open state. A subframe in which two machines 1 can be installed back to back may be connected, or adjacent unit islands 2 installed adjacent to each other may be connected in a game store. In addition, the lowermost part of the island body 3 is configured so that it can be fixed horizontally with an anchor member on an installation rail laid on the floor of the game shop.
[0011]
  The coin circulation mechanism 4 includes a coin storage unit 14 that stores replenishment coins, a coin lifting device 15 (lifting hopper) that lifts coins supplied from the coin storage unit 14, and a coin lifting device 15. And the above-mentioned island body in a state where it is inclined downward from the upper end of the lifting rail 16 along the direction in which the pachislot machines 1 are arranged. 3 and a coin rail at the coin exit provided corresponding to the pachislot machine 1 and the coin lending machine 5 which are a kind of replenishment target devices. A coin detection sensor 21 (lifting counting cell) as a coin detecting means capable of detecting a gate 20 (flow path switching mechanism) and a coin conveyed while rolling inside the conveying rail 17 by its own weight. And an overflow channel 22 that is provided downward from the inclined lower end of the transfer rail 17 and that overflows coins that have passed through the coin outlet of any coin introduction gate 20 to the coin storage unit 14 side, and an overflow channel. 22 is composed of a subcoin storage unit 23 for receiving and storing coins from 22 and a replenishment hopper 24 for supplying coins from the subcoin storage unit 23 to the coin storage unit 14, and a path sequentially passing through these is a circulation of coins It becomes a route. Each device including the coin lifting device 15 and the coin introduction gate 20 operates under the control of the control device 25.
[0012]
  The coin lifting device 15 is installed on the lower side of the island main body 3 and surrounds a coin fitting groove for fitting coins one by one from a coin supply unit 26 provided at the lower end of the coin storage unit 14. Coin delivery plates (not shown) formed at multiple locations in the direction are provided with the spindle tilted obliquely, and the output shaft of a drive motor with a speed reducer (not shown) is connected to the spindle of this coin delivery plate Configured. A coin supply port of a hopper-shaped coin supply unit 26 that supplies coins to be transferred is connected to the coin supply plate, and a lower end inlet of the transfer rail 16 is connected to a coin transfer port forward of the supply port. Connected to the coin supply unit 26 is a lower end outlet of the funnel-shaped coin storage unit 14. Therefore, when the coin feeding device 15 is operated by supplying power to the drive motor based on the signal from the control device 25, the coin delivery plate rotates, and thereby the coin supplied from the coin supply port is placed in the coin fitting groove. The coins are fitted one by one, and when the coin-fitting groove where the coins are fitted arrives at the coin feeding slot, the coins that have been fitted come out of the coin-fitting groove and the coins are fed from the coin feeding slot. 16 are pushed in from the bottom.
[0013]
  When the coin lifting device 15 operates in this way, the coins stored in the coin storage unit 14 can be pushed one by one from the entrance of the lifting rail 16 with a strong force, and the feeding rail 16 is driven by this pushing force. The coins inside can be lifted sequentially. The coin lifting device 15 includes a lifting hopper sensor 27 that detects an internal storage amount such as a coin supply unit 26, and the coin storage unit 14 is for a lifting tank that detects the storage amount at a predetermined position. A sensor 29 is provided (FIG. 9).
[0014]
  In this embodiment, the lifting rail 16 is a flat rail configured so that coins can be aligned and guided in a row with the outer circumferences in contact with each other, and has a groove having a width slightly wider than the thickness of the coin. The formed rail members are arranged in parallel at intervals that allow the concave grooves to face each other and hold coins in both concave grooves, and both rail members are connected by connecting pieces. Therefore, the space between the concave grooves on both sides becomes a coin flow path, and coins are lined up in this coin flow path and are fed. The feed rail 16 can be bent in the width direction or the thickness direction. In this embodiment, a coin polishing device 30 is provided near the upper end of the lifting rail 16 so that the coin can be polished while being lifted.
[0015]
  As shown in FIGS. 4 and 5, the coin polishing apparatus 30 is provided with an abrasive 31 in a state where the coin is sandwiched from both sides of the coin flow path, and the abrasive 31 is slid in contact with the coin to be fed and polished. It is. Specifically, an abrasive 31 such as a non-woven fabric wound around the support material 32 is provided in a state of being urged by a spring or the like toward the coin flow path side in the holder 33, and coins (medals) are formed by sliding contact with the non-woven fabric. Remove any dirt on the surface. Then, the coins purified by passing through the coin polishing device 30 are sent to the transport rail 17 when passing through the upper end of the lifting rail 16.
[0016]
  In addition to the replenishment process and balance process described later, the polishing by the coin polishing apparatus 30 is also performed when the pachi-slot machine 1 has digested a predetermined number (for example, 100 games) without performing the balance process. Depending on the operating status of the pachislot machine 1, the number of coins inserted and the number of prize coins discharged may be balanced so that a replenishment request signal is not output and coins are not circulated for a long time. In order to avoid this, the coin lifting device 15 is operated with all the coin introduction gates 20 closed, and polishing is performed while circulating the coins.
[0017]
  As shown in FIG. 6, the transport rail 17 has spacer plates 34 that are slightly thicker than the thickness of the coins arranged substantially in parallel at a vertical interval wider than the diameter of the coins, on both side surfaces of both spacer plates 34. The side plate 35 is abutted and fixed, and the coin stands up inside.didThis is a flat rail that forms a rolling coin flow path that can be aligned and rolled in a row in a state. The spacer plate 34 arranged below is divided into a plurality of parts, and the diameter of the coin is formed at a portion that becomes a coin outlet 36. It is arranged with a slightly larger interval. Therefore, the coin outlet 36 opens downward at the lower portion of the transport rail 17, and the upper edge of each lower spacer plate 34 disposed across the upper opening edge of each coin outlet 36 functions as a coin rolling part. .
[0018]
  The number of coin outlets 36 formed on the transport rail 17 is the maximum number of replenishment target devices installed on the island body 3. That is, the island main body 3 shown in the present embodiment can have a maximum of four pachislot machines 1 and four coin lending machines 5, so a total of eight coin outlets 36 are formed. A coin introduction gate 20 to be described later can be attached to these coin outlets 36. In this embodiment, a total of six coins are associated with four pachislot machines 1 and two coin lending machines 5. The coin introduction gate 20 is attached to the outlet 36, and the remaining two coin outlets 36 on the downstream side are fitted with plugs 37 from below so that the coin can be rolled and moved without trouble.
[0019]
  Further, as shown in FIG. 3, the connecting portion between the upper end of the lifting rail 16 and the inclined upper end of the conveying rail 17 has a curved flow path bent at a curvature that allows a coin to pass smoothly at the upper end portion of the lifting rail 16. The outlet of the curved flow path is connected to the inlet of the transport rail 17 by forming and fixing the connecting plate member 40 from both sides. In the present embodiment, the vicinity of the outlet of the curved flow path is set as the highest position 41 of the coin flow path, which is downstream of the highest position 41 and upstream of any coin outlet 36, that is, rises. A coin detection sensor 21 is provided on the downstream side of the position where the coin starts to descend and on the upstream side of the first coin introduction gate 20.
[0020]
  The coin detection sensor 21 is a sensor that detects one coin that flows down the rolling coin flow path of the transport rail 17. Therefore, the coin that has passed the highest position 41 starts to flow while rolling while standing in the rolling coin flow path of the transport rail 17 and is detected by the coin detection sensor 21 before the coin is opened. The pachislot machine 1 or the coin lending machine 5 is supplied from the gate 20. And if the control apparatus 25 counts the detection signal from the coin detection sensor 21, it can know the number of coins supplied through the detection sensor 21.
  The coin detection sensor 21 may have any configuration as long as it can detect a passing coin, and may be a proximity switch, a photo sensor, a micro switch, or the like.
[0021]
  As shown in FIGS. 6 to 8, the coin introduction gate 20 has a through window portion that penetrates the thickness direction of the rail on the side surface of the transport rail 17, and the guide portion of the take-in base 42 is formed in this through window portion. Is inserted and fixed with screws or the like, and the slider 43 is placed on the guide portion. The plunger mounting portion of the slider 44 is attached to the plunger mounting portion of the slider 43 so that the slider 43 is attached to the transport rail 17. By opening and closing from the side, the inlet provided in the guide is opened or closed.
[0022]
  For example, since the solenoid 44 is demagnetized in a normal state, as shown in FIG. 8A, the slider 43 is advanced by the urging of a spring (not shown) and stopped in a state where the inlet is closed. . In this closed state, the upper surface of the slider 43 becomes the bottom surface of the coin flow path, and even if the coin rolls in the rolling coin flow path as shown on the left side of FIG. It is not introduced from the (coin outlet 36), and can be passed through the slider 43 and sent downstream.
[0023]
  On the other hand, when the solenoid 44 is excited by a signal from the control device 25, as shown on the right side of FIG. 8B, the slider 43 moves backward to open the inlet (coin outlet 36) and convert it to an open state. When converted to the open state in this way, the coins that have rolled in the rolling coin flow path fall to the introduction port (coin outlet 36), and therefore take charge through the introduction hose 45 connected to the introduction port. Coins can be supplied to the pachislot machine 1 and the coin lending machine 5.
[0024]
  Since the coin introduction gate 20 is introduced to the pachislot machine 1 side or the coin lending machine 5 side in charge of the coins that have flowed down, as described above, the pachislot machine 1 installed on the island body 3 and the coin lending machine 5 The total number is provided. Since this main frame 6 is introduced into four pachislot machines 1 and two coin lending machines 5, a total of six places are provided. When there is a shortage of coins in any one of the devices of the pachislot machine 1 or the coin lending machine 5, a supply request signal is sent from the device to the control device 25, and the control device 25 receives the signal based on the reception of this signal. A signal is output to the coin introduction gate 20 corresponding to the above, whereby the coin introduction gate 20 can be opened and coins can be replenished. The coin supply process will be described later in detail.
[0025]
  The overflow channel 22 may have any configuration as long as the coin can be guided from the coin flow outlet at the lower inclined end of the transport rail 17 to the coin storage unit 14 side. In this embodiment, the inner diameter is larger than the coin diameter. It consists of a large flexible pipe. And the coin discharged | emitted from the lower end exit of the overflow flow path 22 is collected by the sub coin storage part 23 of the supply hopper 24 in this embodiment.
[0026]
  The replenishment hopper 24 has substantially the same configuration as that of the coin lifting device 15 and includes a coin feeding plate having a plurality of coin fitting grooves formed in the circumferential direction and a drive motor with a speed reducer, and the support shaft is inclined obliquely. A coin delivery plate is disposed at, and an output shaft of a drive motor with a speed reducer is connected to this support shaft (none is shown). Then, when the other end of the replenishment rail 46 having one end connected to the coin delivery portion of the replenishment hopper 24 is connected to the coin storage portion 14 of the coin lifting device 15, It operates based on a signal from the control device 25 and is configured so that coins supplied from the sub coin storage unit 23 can be supplied to the coin storage unit 14 from the supply hopper 24 via the supply rail 46.
[0027]
  The replenishment rail 46 is a flat rail configured so that coins can be aligned and guided in a standing state in which the outer circumferences are in contact with each other, like the transport rail 16 and the coin replenishment rail 46.
  The supply rail 46 has one end on the inlet side connected to the coin delivery portion of the supply hopper 24, and the inlet side portion extends upward. The entrance side portion is bent at a position sufficiently higher than the upper surface opening of the coin storage portion 14 with a curvature that allows coins to pass smoothly toward the coin storage portion 14 side, and is inclined downward toward the coin storage portion 14 side. It is extended in the state. Furthermore, the other end on the outlet side is bent downward with a curvature that allows coins to pass smoothly above the coin storage portion 14.
  Therefore, when the supply hopper 24 is operated, the coins stored in the sub coin storage unit 23 are guided by the supply rail 46 and supplied to the coin storage unit 14.
[0028]
  A replenishment counting sensor 47 is provided downstream of the inflection point of the inlet side portion. The replenishment counting sensor 47 detects the number of coins that have passed, so that the number of coins replenished to the coin storage unit 14 can be known by counting the detection signals from the replenishment counting sensor 47.
  When the coins in the sub coin storage portion 23 of the replenishment hopper 24 are insufficient, the replenishment tank sensor 49 sends a coin shortage signal to the control device 25, and the control device 25 that receives this signal receives information on the upper front of the unit island 2. The alarm 50 in the control room or an alarm in the management room notifies the coin shortage by a lamp display or an alarm sound, and prompts the user to insert coins into the unit island 2 from the external coin insertion slot 51.
[0029]
  Next, control by the control device 25 that controls the coin lifting device 15 and the coin introduction gate 20 in the unit island 2 having the above-described configuration will be described.
  As shown in FIG. 9, the control device 25 is mainly composed of a one-chip microcomputer 52 having a ROM storing a control program and the like and a RAM functioning also as a work area, and an input / output interface 53. The various sensors and switches such as the detection sensor 21 are connected, and the flow path switching solenoid 44 of the coin introduction gate 20 is connected.
[0030]
  Then, when there is a supply request from the pachislot machine 1 or the coin lending machine 5 that is the supply target device, the control device 25 switches the coin introduction gate 20 corresponding to the corresponding supply target device to the open state. The coin that has been switched to the open state after the coin lifting device 15 is later activated and the operation of the coin lifting device 15 is stopped based on a predetermined number of coins detected by the coin detection sensor 21. Regardless of the position of the introduction gate 20, a replenishment control means for switching the coin introduction gate 20 from the open state to the closed state after the same predetermined time has elapsed.
[0031]
  In this way, the replenishment control means determines whether the coin introduction gate 20 that is closest to the coin detection sensor 21 is located, regardless of where the coin introduction gate 20 that is operated to replenish coins is located. Even when the coin replenishment operation is performed, even the farthest coin introduction gate 20 or the coin introduction gate 20 disposed in the middle is controlled to return from the open state to the closed state after the same predetermined time has elapsed. . Therefore, even if the coin introduction gate 20 is provided at any coin outlet 36 of the transport rail 17 or the coin introduction gates 20 are provided at all coin outlets 36 according to a request from the game store, the control device 25. The same can be used regardless of the specifications. And the coin circulation mechanism 4 such as the same transport rail 17 and the same control device 25 can be used for a single-sided island.
[0032]
  The predetermined time is the time when the coin starts to freely roll down on the transport rail 17 by its own weight, that is, after passing through the highest position 41, the coin outlet 36 at the end, that is, the plug 37 in this embodiment is the most closed. The time required to reach the coin outlet 36 located downstream (for example, 10 seconds) is set. This predetermined time is set on the floor of the amusement store under the same conditions when the unit island 2 is installed, so it can be set based on the time obtained by experiments in the factory. it can.
[0033]
  If it is not easy to specify the highest position 41 of the transport rail 17, the coin starts to roll down freely on the transport rail 17 and is detected by the coin detection sensor 21 until reaching the terminal coin outlet 36. The time required may be set. Since the detection of the coin detection sensor 21 is the starting point of timekeeping, it is clear.
[0034]
  Further, the replenishment control means in the present embodiment is configured such that after coin replenishment is completed, the coin introduction gate 20 that has performed the coin introduction operation returns to the closed state and then the coin introduction gate 20 is subjected to a coin biting operation by the opening / closing operation again. A prevention process is performed.
  The coin biting prevention process is a process of dropping the coins sandwiched when the coin introduction gate 20 is closed, and the closed coin introduction gate 20 may be opened again and then closed. Specifically, in this embodiment, by energizing the solenoid 44 for 1 second and switching it to the open state, demagnetizing it for 1 second and returning it to the closed state twice, even if a coin is bitten by any chance , It is set to drop this coin. The coin biting prevention process may be opened and closed so that the bited coin can be dropped.
[0035]
  In addition, after the coin replenishment has been completed (in this embodiment, since the coin biting prevention process is performed, this process is terminated), no replenishment request is issued from any replenishment target device. On the condition, the coin lifting device 15 is operated with all the coin introduction gates 20 closed, and the coins are cyclically polished.
[0036]
  The replenishment process by the control device 25 will be described in detail. As shown in the flowchart of FIG. 10, coin replenishment from any replenishment target device, that is, the installed pachislot machine 1 or coin lending machine 5 is always performed during operation. Whether the request signal is input is monitored (ST1). When a coin supply request signal is input from any device and the signal continues for a predetermined time (for example, 5 seconds), the supply request is confirmed, and a predetermined time (for example, 10 seconds) has elapsed since the determination. If so, the process proceeds to replenishment processing, and the corresponding supply port (coin outlet 36) is opened (ST2). That is, the device such as the pachislot machine 1 that outputs the coin supply request signal is specified, and the solenoid 44 of the coin introduction gate 20 corresponding to this device is excited to switch the coin outlet 36 to the open state. Then, after the conversion to the open state, when a predetermined time (for example, 2 seconds) has elapsed, the operation of the coin lifting device 15 (hopper) is started (ST3), and the coin is lifted.
[0037]
  When the coin lifting device 15 is activated and the coin is lifted through the coin lifting rail 16, the coins that have passed through the highest position 41 roll one by one on the rolling coin flow path of the transport rail 17 to the downstream side. The coin is replenished to the device that has sent the coin replenishment request signal through the introduction hose 45 connected to the introduction port. When coins are replenished in this way, the coin detection sensor 21 detects coins one by one and sends a signal to the control device 25. By counting up a counter (not shown) one signal at a time, the number of coin passages can be counted.
[0038]
  Then, it is monitored whether or not the number of coins passed (that is, the number of sheets to be transferred) reaches a set number (ST4), and if it does not reach the set number (for example, 500), it is confirmed whether a coin jam has occurred (ST5). . In this embodiment, when the coin detection sensor 21 does not count for 10 seconds, or when it continues to be detected, it is determined that the coin is jammed and error processing is performed. In this error processing, for example, the information notification device 50 on the unit island 2 is turned on or blinked to notify the abnormality.
[0039]
  On the other hand, if it is confirmed that no coin jam has occurred, it returns to the coin ST4 again to monitor whether the set number of sheets has been transferred, and if reached, whether or not the replenishment device sufficient condition is satisfied in the corresponding device, for example, pachislot If it is confirmed that the continuity sensor provided in the coin storage unit 14 of the machine 1 has sufficiently output a signal by the replenished coin (ST6) and it is confirmed that the sufficient condition of the replenishing device is satisfied by the sufficient signal output If the hopper (coin-lifting device 15) stops operating (ST7), on the other hand, if the signal is not sufficiently confirmed, the process returns to ST4, and after confirming the coin-feeding number again, the replenishment device sufficient signal is output. Check.
[0040]
  If the operation of the hopper is stopped, after a predetermined time (for example, 10 seconds) has elapsed, the solenoid 44 of the corresponding coin introduction gate 20 is demagnetized and the corresponding supply port (coin introduction port) is closed (ST8). For example, a coin biting prevention process is performed in which the solenoid 44 is excited twice for one second and then demagnetized for one second (ST9).
[0041]
  If the coin exit 36 is closed in this way, next, it is monitored whether or not there is a new supply request (ST10), and if there is, the process returns to ST2 to perform the above-mentioned processing. Then, the process proceeds to the polishing circulation process (ST11).
[0042]
  In this polishing circulation processing, the coin detection state is detected by the coin detection sensor 21, and the coin circulation state is monitored to polish the coin. For example, if the coin feeding device 15 is turned on (operated) for a predetermined time (1 minute), then it is turned off (stopped) for a predetermined time (1 minute), and this cycle is repeated a predetermined number of times (three times). Monitor for normal circulation, ie normal polishing.
[0043]
  When coins are normally circulated, the coin detection sensor 21 detects the circulating coins one by one and sends a coin detection signal to the control device 25. By monitoring the off interval in the same manner as the coin jam detection described above, the circulation of coins can be monitored.
[0044]
  By the way, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
[0045]
  For example, the gaming machine is not limited to the pachi-slot machine 1 as long as it plays a game by inserting coins.
  Further, the coin introduction gate 20 is not limited to the above-described configuration, and may be any configuration as long as the coin that has tumbled down on the transport rail 17 can be taken into the supply target device in charge. The structure which switches the flow path which rolls to a horizontal direction may be sufficient.
  The predetermined time set in the replenishment control means is 10 seconds in the embodiment, but is not limited to this, and can be set to an appropriate length. In addition, an adjustment operation unit may be provided in the control device so that the predetermined time can be finely adjusted when setting.
[0046]
【The invention's effect】
  As described above, the present invention has the following effects.
