Description

The present invention relates to a gaming machine including a substrate unit in which a substrate is housed in a transparent substrate case.

Many boards arranged in a game machine are housed in a transparent board case and mounted as a board unit. Some of these board units are provided with a plurality of boards in order to increase the component standardization rate. For example, in the substrate unit described in Patent Document 1, two substrates connected to each other in the plate surface direction are housed in a substrate case.

Japanese Unexamined Patent Publication No. 2012-095879 (see FIG. 29)

By the way, in the board unit described in Patent Document 1, since two boards for board-to-board connection are housed in one board case, the two boards cannot be separated and connected unless the board case is opened. .. Further, when the two boards are separated and connected by hand, there is a possibility that the parts mounted on the boards may come into contact with each other and be damaged.

The present invention is an attempt to solve such a problem, and is a game in which two boards connected to each other can be easily separated and connected, and the mounted components are not damaged when the boards are separated and connected. The purpose is to provide a machine.

The first invention of the present invention includes a first substrate and a second substrate which are connected to each other so as to be continuous in the plate surface direction via a pair of connectors arranged on one side of each. In a game machine, the first substrate is housed in a first board case to form a first board unit, and the second board is housed in a second board case to form a second board. The first substrate and the second substrate, which constitute a substrate unit, can be separated and connected to each other in a state of being housed in the substrate case, respectively, and the first substrate case and the first substrate can be connected to each other. In at least one of the two board cases, the mating direction and / or the fitting direction of the pair of connectors on the surface side facing the board surface on which the first board and / or the components of the second board are arranged. A usage direction display unit indicating the separation direction is provided, and the first substrate and / or the second substrate has a height protruding from the plate surface at a portion facing the usage direction display unit. The usage direction display unit inside the board case provided with the usage direction display unit due to the bending generated by pressing a finger against the usage direction display unit when the two boards are separated and connected together with the substrate unit. There are no components above a predetermined height that may come into contact with the region corresponding to the above, and the first substrate and the second substrate are taller than the passive component and the passive component. The gaming machine is characterized in that the passive component is installed at a portion where the component is installed and faces the usage direction display unit.

In such a configuration, since the first substrate and the second substrate can be separated and connected without opening the substrate case, the first substrate and the second substrate can be easily separated and connected. Further, if the first board and the second board are separated and connected while being housed in the board case, there is no risk of contacting and damaging the parts on the board at the time of separation and connection, and fraudulent acts against the board. It becomes easy to prevent. Further, in the conventional configuration, since two substrates are housed in one substrate case, when one substrate is replaced with a substrate having a different shape, the substrate case cannot be reused, but the first invention of the present invention. If so, there is an advantage that the substrate case of the other substrate can be diverted even when one substrate is replaced with a substrate having a different shape.
Further, in the first invention of the present invention, since the two substrates are separated and connected in a state of being housed in the substrate case, it is difficult to visually recognize the connector as compared with the case of separating and connecting the exposed substrates. In the first invention, since the usage direction of the connector is known by the usage direction display unit provided on the board case, no problem occurs even if the board is separated and connected while being housed in the board case.
Further, in the first invention of the present invention, by providing the usage direction display unit, it is expected that a finger is pressed against the usage direction display unit when the two substrates are separated and connected together with the substrate unit. In the first invention of the present invention, since the parts having a predetermined height or higher are not arranged in the portion facing the usage direction display portion, even if the substrate case to which the finger is pressed bends toward the substrate in the usage direction display portion. , There is no possibility that the parts arranged in the portion facing the usage direction display portion will be pressed against the board case and damaged.

In the first invention of the present invention, a pair of identification labels on which a code optically readable by a reader is printed are printed on the first substrate unit and the second substrate unit on substantially the same plane. It is proposed that the pair of identification labels have substantially the same size and are affixed so as to be adjacent to each other, and identification information relating to the substrate unit to which each is affixed is recorded.

In such a configuration, if the reading device focuses on the code of one identification label and reads the identification information, the code of the other identification label can be read by simply sliding the imaging area of the reading device slightly. Since it can be read, the codes of the two identification labels can be read efficiently.

Further, in the first invention of the present invention, the first substrate case and the second substrate case are fitted and separated from each other as the pair of connectors are fitted and separated. A combined structure is provided, and a configuration is proposed in which an end edge orthogonal to the fitting direction and the separating direction is formed at the tip of the pair of fitting structures, respectively.

In such a configuration, by confirming whether or not the tips of the fitting structures of the first board case and the second board case are parallel to each other, the connectors of the two boards are fitted without tilting. You can judge whether you are doing it.

Further, in the first invention of the present invention, the first substrate case and the second substrate case are formed with ribs extending along the side edges of the pair of connectors on the inner side of the ribs. It is proposed that at least a part of the configuration is formed inside the arrangement portion of the usage direction display portion.

In such a configuration, ribs can prevent unauthorized equipment from being inserted into the case through an opening formed in the substrate case in accordance with the connector. Further, the ribs can increase the strength of the substrate case in the usage direction display portion and reduce the amount of bending when pressed by a finger.

Further, in the first invention of the present invention, it is proposed that the surface of the first substrate case and / or the second substrate case is roughened at a portion where the usage direction display portion is formed. ..

In such a configuration, since the use direction display unit is less likely to slip, it becomes easier to work by pressing a finger against the use direction display unit when separating and connecting the first substrate and the second substrate. Further, since the transparency of the usage direction display unit is lowered, the visibility of the usage direction display unit can be improved.

The second invention of the present invention is a substrate in which a substrate device in which child substrates smaller than the parent substrate are arranged in a laminated manner on one surface side of the master substrate and the substrate is connected to the substrate is housed in a transparent substrate case. A gaming machine including a unit, the substrate unit is arranged so that one side of the parent substrate can be visually recognized, and identification information is provided on the child substrate on a side not facing the master substrate. The identification label shown is affixed, and the identification label indicating the identification information is not affixed to the side facing the parent substrate, and the master substrate is difficult to see from the one side due to the lamination of the child substrates. It is a gaming machine characterized in that an identification label indicating identification information is not attached to the area.

In such a configuration, the identification label is arranged closer to the viewpoint of the person in charge of viewing, as compared with the case where the identification label is arranged on the outer peripheral portion of the parent substrate as in the conventional configuration. The visibility of the label can be improved.

In the second invention of the present invention, it is proposed that the identification information indicated by the identification label includes a model name.

In such a configuration, it is not necessary to attach an identification label indicating the model name to the dead space of the parent board, so that the dead space of the parent board can be reduced and the board device can be miniaturized.

Further, in the second aspect of the present invention, it is proposed that the identification label is printed with a code on which identification information is recorded and which can be optically read by a reading device.

In such a configuration, the code is easier to read by the reading device because the identification label is arranged on the front side as compared with the conventional configuration in which the identification label is attached to the outer peripheral portion of the parent substrate.

The substrate case is provided with a bulging portion that bulges most at a portion where the child substrate is arranged, and the substrate case is located at the upper part or the lower part of the reel unit when viewed from the front. It is proposed that the bulge portion overlaps with any of them and is formed at a position where the bulge portion does not overlap with the reel unit in a front view.

In such a configuration, the substrate case provided with the bulging portion and the reel unit provided with the cylindrical reel can be appropriately arranged close to each other without interfering with each other, so that the internal space of the housing can be effectively utilized.

Further, in the second aspect of the present invention, a housing and a front door covering the front side of the housing are provided, and the substrate unit is disposed on one of the housing and the front door. The side of the substrate device on which the child substrate is arranged faces the other of the housing and the front door, and the substrate case has the largest bulge at the portion where the child substrate is arranged. A portion is formed, and a specific unit is arranged on the other side of the housing and the front door at a position where the front door is closed and overlaps with the substrate case in front view and plan view. It is proposed that the bulge portion is formed at a position where the bulge portion overlaps with the specific unit in a plan view and does not overlap with the specific unit in a front view with the front door closed.

In such a configuration, the substrate case provided with the bulging portion can be appropriately arranged in close proximity without interfering with a specific unit arranged at the opposite position, so that the internal space of the housing can be effectively utilized.

Further, in the second aspect of the present invention, a plurality of through holes are formed in the substrate case, and the through holes do not overlap with the identification label when visually recognized from the front side of the identification label. A configuration is proposed in which at least a part of the identification label is formed in the vicinity of the identification label.

In such a configuration, the air around the identification label can be replaced through the through hole without impairing the visibility of the identification label, so that the identification label is peeled off by the heat generated by the surrounding electronic devices. It is possible to suppress the label and discoloration.

Further, in the second invention of the present invention, the child substrate has a rectangular shape, and a connector for connecting the parent substrate and the substrate to the substrate is arranged near one side of the child substrate. Is fixed to a spacer disposed on the parent substrate with a screw at least on the opposite side of the one side, the spacer and the screw are made of metal, and the child substrate is made of the spacer and the screw. A configuration is proposed in which the GND wiring is exposed at the fastening portion.

In such a configuration, there is an advantage that a spacer or a screw for holding the child substrate in a laminated manner on the parent substrate can be used as a ground wire for the child substrate.

In the third invention of the present invention, the power supply device that supplies power through at least two power supply lines of the first power supply line and the second power supply line, and the first power supply line and the second power supply line are both provided. A drive device including a board to be connected, in which power is supplied to at least the logic circuit of the control device via the first power supply line, and at least controlled by the control device via the second power supply line. A first monitor lamp indicating the energized state of the first power supply line and a second monitor lamp indicating the energized state of the second power supply line are provided on one surface side of the substrate. Immediately after the power supply of the power supply device is turned off, at least a part of the stored electric charge is supplied to the first monitor lamp to delay the extinguishing of the first monitor lamp. Immediately after the power supply of the power supply device is turned off, at least a part of the stored electric charge is supplied to the second monitor lamp to delay the extinguishing of the second monitor lamp, and the second power storage device is provided. The second power storage device has a longer discharge time than the first power storage device, and immediately after the power supply of the power supply device is turned off, the second power storage device discharges for a longer time than the first power storage device. The gaming machine is characterized in that the extinguishing of the second monitor lamp is delayed more than the extinguishing of the first monitor lamp.

In such a configuration, even after the power supply from the power supply device to each power supply line is stopped, power is temporarily supplied to the monitor lamp from the first power storage device and the second power storage device, and the two power storage devices Since each monitor lamp continues to light according to the discharge time, it is possible to easily confirm the turn-off order of each monitor lamp by appropriately setting the discharge time of each power storage device.

In the third invention of the present invention, the second monitor lamp is configured to be turned off after 5 seconds or more have passed since the first monitor lamp was turned off after the power of the power supply device was turned off. Is proposed.

If a difference of 5 seconds or more is provided between the turn-off timings of the two monitor lamps as in this configuration, the afterimage effect when the monitor lamps are turned off can be eliminated, so that the turn-off order of the monitor lamps can be accurately visually confirmed. ..

A relay board that relays a power supply line, the first power storage device is connected to the first power supply line closer to the control device than the relay board, and the second power storage device is It is proposed that the second power supply line is connected closer to the drive device than the relay board.

When the first power storage device and the second power storage device are arranged closer to the control device and the drive device than the relay board instead of the relay board as in such a configuration, the load on each power supply line is increased. There is an advantage that it is easy to set an appropriate discharge time according to the size.

Further, in the third aspect of the present invention, the substrate is housed in a substrate case made of a transparent resin, and transparent ribs protruding inward are integrally molded with the substrate case on the inner side surface of the substrate case. It is proposed that the end face of the rib covers the first monitor lamp and / or the second monitor lamp on the substrate from the one side.

In the third invention of the present invention, the bright light of the monitor lamp may interfere with the inspection of the substrate. On the other hand, in such a configuration, the light of the monitor lamp is incident on the end face of the rib and diffused inside the rib, so that the light is changed from a small intense light to a non-intense light emitted in a wide range. , The light of the monitor lamp does not interfere with the board inspection. Although the intensity of the light of the monitor lamp is weakened by the ribs, the ribs emit surface light to provide a wide range of light, so that the lighting state of the monitor lamp can be more easily determined. Therefore, in such a configuration, even when the first monitor lamp and the second monitor lamp are arranged close to each other, there is an advantage that it is difficult to misunderstand the lighting state of each monitor lamp. Further, since the transparent rib is integrally molded with the substrate case, there is an advantage that it can be realized without increasing the number of parts.

Specifically, as shown in FIGS. 14 to 16, in the present embodiment, the first substrate unit 26 is arranged so as to overlap the reel unit 15 in the plan view and the front view in the closed state of the front door 3. .. However, in the front view, only the lower part of the first substrate unit 26 and the upper part of the reel unit 15 overlap, and the bulging portion 60 overlaps with the reel unit 15 in the plan view, but does not overlap with the reel unit 15 in the front view. Arranged like this. With this arrangement, the first substrate unit 26 that inflates the bulging portion 60 to the back side is arranged close to the reel unit 15 that inflates the reels 9a to 9c forward without interfering with each other. Therefore, the internal space of the housing 2 can be effectively utilized.

Although the configuration according to the second invention of the present invention has been described above, the second invention of the present invention is not limited to the embodiment of the present embodiment, and various modifications can be made without departing from the gist of the present invention. For example, although the above embodiment applies the present invention to a slot machine, the present invention can also be applied to a gaming machine such as a pachinko machine. Further, in the present embodiment, the image control board 22 corresponds to the board device according to the second invention of the present invention, but the board device according to the second invention of the present case is another control board or a relay board. May be good. It may be a combination of substrates.

Further, in the present embodiment, the identification label 68a according to the second invention is attached to the ROM 44 arranged on the child substrate 22b, but the identification label according to the second invention is attached to the child substrate 22b. It may be attached to other electronic components or the child substrate main body 43. Further, in the present embodiment, the QR code recording the identification information is printed on the identification label 68a according to the second invention of the present invention, but in the second invention of the present invention, the code printed on the identification label is printed. , The QR code is not limited to the code, and any code that can be optically read by a reading device may be used.

Next, the configuration according to the main part of the third invention will be described.

As described above, the sub-connection board 23 is provided with three monitor lamps 50a to 50c indicating the energized state of the power supply line supplied from the power supply device 18. Each of the monitor lamps 50a to 50c is composed of a bullet-shaped LED, and as shown in FIG. 17, is arranged vertically on the upper portion on the back side of the sub-connection board main body 52. Power is supplied from the power supply device 18 to each device via a power supply line having three types of voltages of 5V / 20V / 30V, and the three monitor lamps 50a to 50c are configured depending on their respective lighting states. It is configured to individually indicate the energized state of the three power supply lines. Specifically, the upper first monitor lamp 50a is lit while the 5V power supply line is energized, the central second monitor lamp 50b is lit while the 20V power supply line is energized, and the lower third monitor is lit. The lamp 50c is configured to light up while the 30 V power supply line is energized.

The lighting state of each of the monitor lamps 50a to 50c can be confirmed through the second substrate case 41 from the back side of the front door 3 in the open state of the front door 3. Here, in this embodiment, as shown in FIG. 10, three horizontally long ribs 65e protruding inward are formed on the inner side surface of the second cover member 41a, and as shown in FIGS. 8 and 17, the respective ribs are formed. The end face of 65e is arranged so as to cover each of the monitor lamps 50a to 50c from the back surface side. Since the rib 65e is a transparent one integrally molded with the second cover member 41a, in this embodiment, the light of the monitor lamps 50a to 50c is incident on the end surface of the rib 65e arranged on the back surface side. It propagates and scatters inside the rib 65e. Therefore, in this embodiment, when visually recognized from the back side of the second substrate unit 27, the light of the monitor lamps 50a to 50c is a wide range of light sources emitted by the entire rib 65e rather than the local point light source of the LED. Is visually recognized as.

In addition, there is an advantage that the light of the monitor lamps 50a to 50c does not easily interfere with the inspection work. Although the intensity of the light of the monitor lamps 50a to 50c is reduced by the ribs 65e, the light emitting portion is expanded by the surface emission of the ribs 65e on the back side of the monitor lamps 50a to 50c. The lighting state becomes easier to determine. Therefore, in this embodiment, even if the three monitor lamps 50a to 50c are arranged close to each other on the substrate, the lights of the adjacent monitor lamps 50a to 50c are not confused and the lighting states of the three monitor lamps 50a to 50c are not misunderstood. .. Further, since the rib 65e is integrally molded with the second cover member 41a case, there is an advantage that it can be realized without increasing the number of parts.

FIG. 18 shows a power supply circuit from the power supply device 18 to the main equipment.
As described above, the power supply device 18 converts an external power source from alternating current to direct current, and supplies power to each device via a power supply line having a power supply voltage of 5V / 20V / 30V. Although not shown, the power of each power supply line is supplied to some devices after being converted to a required voltage by a regulator or the like. As shown in FIG. 18, the three power supply lines are connected to each device via relay boards such as the power supply connection board 80, the sub-connection board 23, the speaker connection board 82, and the effect lamp connection board 83. For example, 5V and 30V power supply lines are connected to the main control board 20 via the power supply connection board 80. The electric power supplied from the 5V power supply line is used as the power supply for the logic circuit of the main control board 20, and the 30V power supply line is used as the driving power for the reel motor 33 and the like via the main control board 20. Further, a 30V power supply line is connected to the payout motor 36 via the power supply connection board 80.

Further, as shown in FIGS. 18 and 19, the three power supply lines are connected from the power supply device 18 to the sub-connection board 23 via the power supply connection board 80. Then, the 5V power supply line is connected to the sub control board 21, the image control board 22, the image display 12, and the accessory drive board 84 via the sub connection board 23, and supplies electric power to those logic circuits. Supply. Specifically, the sub-control board 21, the image control board 22, and the accessory drive board 84 are directly connected to the 5V power supply line from the sub-connection board 23, and the image display 12 is image-controlled from the sub-connection board 23. A 5V power supply line is connected via the board 22. On the other hand, the two power supply lines of 20V and 30V further pass through the sub-connection board 23, the reel back lamp 35, the speakers 11a to 11d, the production lamps 13a and 13b, the image display 12, and the accessory drive motor. It is connected to a drive device such as 10b to supply drive power to each drive device. Specifically, drive power is supplied to the reel back lamp 35 from the sub-connection board 23 via the sub-control board 21 from the power supply line of 30 V. Further, drive power is supplied to the speakers 11a to 11d from the sub-connection board 23 via the speaker connection board 82 from the 20V power supply line. Further, drive power is supplied to the effect lamps 13a and 13b from the sub-connection board 23 via the effect lamp connection board 83 from the power supply line of 30 V. Further, in the image display 12, drive power is supplied from the sub-connection board 23 to the liquid crystal backlight from the 30V power supply line via the image control board 22. Further, drive power is supplied to the accessory drive motor 10b from the sub-connection board 23 via the accessory drive board 84 from the power supply line of 30 V.

As shown in FIG. 19, the three monitor lamps 50a to 50c arranged on the sub-connection board 23 are connected to the three power supply lines relayed by the sub-connection board 23, respectively. Then, when the 5V power supply line is energized, the first monitor lamp 50a is turned on by supplying power from the power supply line to the first monitor lamp 50a, and when the 5V power supply line is not energized, the power supply line is turned on. When the power supply to the first monitor lamp 50a is stopped, the first monitor lamp 50a is turned off. Similarly, when the 20V power supply line is energized, the second monitor lamp 50b is turned on by supplying power from the power supply line to the second monitor lamp 50b, and when the 20V power supply line is not energized, the power supply is supplied. When the power supply from the line to the second monitor lamp 50b is stopped, the second monitor lamp 50b is turned off. Further, when the 30V power supply line is energized, the third monitor lamp 50c is turned on by supplying power from the power supply line to the third monitor lamp 50c, and when the 30V power supply line is not energized, the power supply line is turned on. When the power supply to the third monitor lamp 50c is stopped, the third monitor lamp 50c is turned off.

As described above, in this embodiment, the monitor lamps 50a to 50c of the sub-connection board 23 are turned on / off according to the energized state of each power supply line, so that the staff of the amusement park can turn on the monitor lamps 50a to 50c. By checking, it can be confirmed whether the power supply to each device is performed normally. Here, in this embodiment, when the power switch 31 is switched from ON to OFF and the power supply device 18 is turned off, the turn-off timing of the monitor lamps 50a to 50c is delayed by an appropriate time from the time when the power supply device 18 is turned off. It is configured as. Specifically, as shown in FIG. 19, power storage devices C1 to C9 having a capacitor are connected to each power supply line. One end of each of the power storage devices C1 to C9 is connected to the power supply line and the other end is connected to the ground. When the power supply device 18 supplies power to each power supply line, each of the power storage devices C1 to C9 is supplied with power from the power supply line. The power storage devices C1 to C9 are almost fully charged, and immediately after the power supply of the power supply device 18 is turned off, the power storage devices C1 to C9 release the stored electric charge. Then, in this embodiment, a part of the electric charge released by the power storage devices C1 to C9 immediately after the power is turned off flows into the line to which the monitor lamps 50a to 50c are connected and is used to emit light from the monitor lamps 50a to 50c. As a result, the timing of turning off the monitor lamps 50a to 50c is delayed from the timing of switching the power switch 31 to OFF.

By the way, when the power of the slot machine 1 is turned off, before the power supply to the logic circuit of the sub-control board 21 that controls the drive devices such as the speakers 11a to 11d and the accessory drive motor 10b is stopped, the drive device is supplied with power. When the power supply is stopped, the drive device is stopped before the control process of the sub control board 21 is stopped, and the control command to the drive device is dropped, which is not preferable. On the other hand, the power supply device 18 is a 20V or 30V power supply line used for the drive device in which the sub control board 21 controls the power supply to the 5V power supply line used for the power supply of the logic circuit of the sub control board 21. It is configured to stop before. However, the time difference in the stop timing of each power supply line by the power supply device 18 is so short that it cannot be discriminated by the turn-off timing of the monitor lamps 50a to 50c. Therefore, in this embodiment, the time difference between the turn-off timings of the monitor lamps 50a to 50c is increased by appropriately setting the discharge time (time until the end of discharge) of the power storage devices C1 to C9 connected to each power supply line. Therefore, the order in which the monitor lamps 50a to 50c are turned off can be easily confirmed.

Specifically, in this embodiment, the power storage devices C5 to C9 having extremely large capacities are connected to the power supply lines of 20V and 30V as compared with the power storage devices C1 to C4 connected to the 5V power supply line. When the power is turned off, the discharge time of the power storage devices C5 to C9 connected to the 20V and 30V power lines is longer than the discharge time of the power storage devices C1 to C4 connected to the 5V power supply line. ing. As a result, when the power is turned off, the extinguishing timing of the second monitor lamp 50b and the third monitor lamp 50c is delayed more than the extinguishing of the first monitor lamp 50a. Specifically, as shown in FIG. 20, the extinguishing timing of the first monitor lamp 50a is delayed only about 1 second after the power switch 31 is switched to OFF, whereas the extinguishing timing of the second monitor lamp 50b is delayed. Is delayed by 15 to 20 seconds, and the extinguishing timing of the third monitor lamp 50c is delayed by 8 to 12 seconds. The order of turning off the monitor lamps 50a to 50c can be sufficiently determined if there is a difference of 5 seconds or more in the turn-off timing even if the disturbance factor due to the afterimage effect at the time of turning off is taken into consideration. If the other monitor lamps 50b and 50c are configured to be turned off after 5 seconds or more have passed since the first monitor lamp 50a was turned off, the first monitor lamp 50a can be surely turned off first. Can be visually confirmed.

As described above, in this embodiment, a difference is provided in the discharge time of the power storage devices C1 to C9 connected to each power supply line, and a clear difference is provided in the extinguishing timing of the monitor lamps 50a to 50c immediately after the power is turned off. Therefore, there is an advantage that the turn-off order of the monitor lamps 50a to 50c can be easily confirmed.

In particular, in this embodiment, the power storage devices C1 to C4 connected to the 5V power supply line are connected to the load side (closer to the control device) of the power supply line than the sub-connection board 23, and are 20V and 30V. The power storage devices C5 to C9 connected to the power supply line are connected to the load side (closer to the drive device) of the power supply line than the sub-connection board 23. With such a configuration, the number and capacity of the power storage devices C1 to C9 can be easily set according to the number of drive devices arranged in the slot machine 1 and the power consumption. Therefore, the monitor lamps 50a to 50a when the power is turned off. There is an advantage that the turn-off delay time of 50c can be easily set.

Further, in the present embodiment, the monitor lamps 50a to 50c are arranged on the sub-connection board 23, but the monitor lamps according to the third aspect of the present invention are arranged on the main control board 20, the power supply connection board 80, and the like. You may be. Further, in this embodiment, the delay in turning off the monitor lamps 50a to 50c after the power supply device 18 is turned off is about 1 second for the first monitor lamp 50a, 15 to 20 seconds for the second monitor lamp 50b, and the third monitor. The lamp 50c is configured to take 8 to 12 seconds, but the third invention of the present invention is not limited to the delay time, and after the power is turned off, the lamp 50c is more than the first monitor lamp (first monitor lamp 50a). It suffices as long as it can be easily confirmed that the second monitor lamp (second monitor lamp 50b or third monitor lamp 50c) is turned off with a delay. It is desirable that the discharge time of the power storage devices C5 to C9 is set so that the turn-off delay time of the monitor lamps 50b and 50c after the power is turned off is within 30 seconds as in this embodiment. This is because if the discharge time of the power storage devices C5 to C9 is made too long, the drive device continues to be in a driveable state without control, and there is a high possibility that the drive device will fail for some reason.

Further, in the above embodiment, the sub control board 21 corresponds to the control device according to the third aspect of the present invention, and the accessory drive motor 10b, the speakers 11a to 11d, the effect lamps 13a and 13b, and the reel back lamp 35 are the present invention. Although it corresponds to the control device according to the third invention, the third invention of the present invention can be applied to other than the combination of these control devices and the drive device. Further, in the above embodiment, the 5V power supply line exclusively supplies power to the logic circuit, and the 20V and 30V power supply lines exclusively supply drive power to the drive device. The power supply line of the above may supply a part of the electric power to other than the logic circuit, and the second power supply line according to the third invention of the present invention supplies a part of the electric power to other than the drive device. It may be.

Further, in the present embodiment, the end faces of the ribs 65e are arranged on the back side of all the monitor lamps 50a to 50c, but in the third invention of the present invention, the ribs are arranged only on the back side of some of the monitor lamps 50a to 50c. Includes a configuration in which the end faces of 65e are arranged. For example, it is proposed that the end face of the rib 65e is not arranged on the back side of the first monitor lamp 50a, but the end face of the rib 65e is arranged on the back side of the second monitor lamp 50b and the third monitor lamp 50c. In such a configuration, the light of the first monitor lamp 50a that is directly visible without the rib 65e, and the second monitor lamp 50b and the third monitor lamp 50c that are indirectly visible through the rib 65e. As described above, when checking the lighting order of the first monitor lamp 50a and the other monitor lamps 50b and 50c when the power is turned off, the monitor lamps 50a to 50c are misidentified.
