Description

The present invention
It is about.

  In game machines, for example, pachinko machine game boards, specific areas in which rights such as winning balls and lotteries can be obtained, such as winning holes (start winning holes, general winning holes, etc.), and starting passage holes (chuckers, starting holes) Passing area) is provided. The ball detection sensor detects the pachinko ball by passing the pachinko ball, and in the case of a general winning opening, takes it into the gaming machine after detection and pays out a predetermined number of game balls as prizes for the detected ball ) In the case of the start winning opening, the right lottery (special symbol lottery) is performed at the detection timing of the pachinko ball. As an example, when the special symbol lottery is won, as a big hit process, a special winning opening (attacker) separately provided is opened a predetermined number of times in a predetermined time unit, so that a player can receive a lot of prize balls in a short period of time. A special game that can be received is executed.

  In the game specifications as described above, there is a case in which a decorated accessory device is provided as means for stimulating the interest of the player in the game. “Amusement for the player's game” includes, for example, the degree of expectation that the special symbol lottery may be won, and the sensuously flashy production is highly anticipated, so Expectation is low. As an absolute index, for example, when a lighting target emits light, the emission color may be set in the order of high expectation, such as red → green → yellow.

  By the way, there are some accessory devices attached to the game board that are related to the progress of the game, and there are those that simply produce an effect, and in particular, the light emitted from the light source (light emitting element, lamp, etc.) is used for the effect. In some cases, a decorative device that is used, that is, an electrical decoration device is mounted.

  For example, light emitting elements applied as light sources in game machines are mainly LED elements from the viewpoint of power saving. The electrical decoration device is configured by a combination of the direct light of the LED element, the indirect light by the light guide member and the like, and a decorative member that has been subjected to high reflection processing such as chrome plating.

  However, in the case of the above configuration, in order to emit light from the LED element, an electric wiring board on which electronic components for supplying electric power and controlling light emission are attached is essential. On the other hand, in the decorative member, since the chrome plating has conductivity, static electricity is accumulated in the decorative member by contact with a static pachinko ball or the like, and the accumulated static electricity is eventually discharged. This discharge (electrostatic noise) causes electrical destruction of electronic components attached to the electric wiring board arranged close to the decorative member, and thus avoids electrostatic noise on the decorative member and the substrate. Grounding (earthing) is also essential.

  For this reason, Patent Document 1 discloses that a decorative member and an electric wiring board serving as a base of an LED element are fastened together with a conductive screw, and static electricity that is easily accumulated due to grounding is discharged. It describes that measures should be taken.

JP 2009-11412 A

  However, in the prior art including Patent Document 1, there are not a few things, and the accessory device including the electrical decoration device requires some kind of grounding treatment. As the number of parts for the grounding treatment increases, for example, conductive screws Due to the grounding process such as co-fastening, the assembling workability of the entire accessory device is lowered.

  In consideration of the above facts, the present invention allows the influence of static electricity stored in the game ball on the substrate of the light source unit for the light production in the accessory device without deteriorating the workability of the accessory device. The object is to obtain a gaming machine that can be avoided as much as possible.

The present invention is a gaming machine in which a visual presentation is performed to alert a player in accordance with the progress of a game executed on a game surface of a game board. A light source unit provided with an electric wiring board for controlling, a grounding means for grounding the electric wiring board applied to the electric wiring board of the light source unit, and the electric wiring board of the light source unit. Is a light guide member that is electrically and physically non-contact, is disposed at a predetermined position, receives light from the light source from one end face, and outputs light from the other end face, and the light guide. A accessory device provided with a decorative member that is provided with a through-hole that sandwiches the optical member and includes a metal plating layer and can accumulate static electricity,
A metal mirror finish layer capable of accumulating static electricity is provided on the inner surface of the through hole that directly contacts when the light guide member is sandwiched , similarly to the metal plating layer .

  According to the present invention, since the light source is provided on the electric wiring board, and the electric wiring board is grounded by, for example, the ground wire, the accumulated static electricity is discharged.

  On the other hand, since the accessory device that requires light as one of the effects is electrically and physically non-contact with the electrical wiring board and the light source, even if static electricity is accumulated in the accessory device, the electrical device is directly connected. There is little effect on the substrate.

  On the other hand, by introducing light from the light source remotely to the light guide member constituting a part of the accessory device, it is possible to produce light in the accessory device while eliminating the accumulation of static electricity. For example, it is not necessary to ground the accessory device, the number of parts can be reduced, and the assembly workability can be improved.

  In the present invention, the light guide member has an end face for receiving light and a surface excluding the end face for outputting light, which are closed by a closing member.

  It is possible to suppress the unnecessary light output from the light guide member, which is a light loss other than the light loss for receiving the light arriving from a distance, to the minimum, and to efficiently output the received light it can.

  The blocking member is a decorative body that has been subjected to a mirror surface treatment including chrome plating, and constitutes a part of the accessory device together with the light guide member.

  By using a mirror finish such as chrome plating, light leakage from the inside of the light guide member can be reliably reflected and returned to the light guide member.

  The light source unit and the accessory device are arranged on the front and back surfaces of the game board.

  Since the light source unit and the accessory device are separated by at least a distance corresponding to the thickness of the game board, even if static electricity accumulated in the accessory device is discharged, the light source unit is caused by discharge noise at that time. The electrical wiring board is not destroyed.

  As described above, according to the present invention, the effect of static electricity stored in the game ball on the substrate of the light source unit for the light effect in the accessory device can be reduced without reducing the workability of the accessory device. It has an excellent effect that it can be avoided.

  A light emitting element 202 is disposed so as to face the light receiving surface 200B. The light emitting element 202 is attached to the electric wiring board 208 disposed on the set plate 206 described above. For example, the light emitting element 202 includes a set of LED light emitting elements that emit three primary colors of red, green, and blue (so-called RGB) light.

  The electrical wiring board 208 including the light emitting element 202 is in an electrically and physically non-contact state with the center actor 105. That is, the center accessory 105 is attached to the front side of the game board 18, and the electric wiring board 208 is attached to the back side of the game board 18, and at least the thickness dimension of the game board 18 is separated. Here, the light emitted from the light emitting element 202 passes through the through hole 18A provided in the game board 18 and is input to the light receiving surface 200B of the light guide member 200, and from the light receiving surface 200B. The received light is guided inside the light guide member 200 and is emitted from the light emitting surface 200A.

The center accessory 105 is attached so that the light guide member 200 is sandwiched in a part thereof, and the surface of the center accessory 105 is subjected to a mirror finish (chrome plating layer 210). The chrome plating layer 210 is also applied to the side surface that sandwiches the light guide member 200. As a result, the light received from the light receiving surface 200 </ b> A of the light guide member 200 is guided to the light emitting surface 200 </ b> A without leaking from the side surface in contact with the side surface provided with the chrome plating layer 210.

  On the other hand, a set plate 206 is disposed on the lower surface (back surface) side of the game board 18. On the set plate 206, an electric wiring board 208 to which the light emitting element 202 is attached is disposed so as to face the through hole 18 A of the game board 18. In addition, the electrical wiring board 208 is electrically connected to the set plate 206 via the ground wire 212. Since the set plate 206 itself has been previously grounded (see the grounding mark 207 in FIG. 7), the electrical wiring board 208 is grounded as a result.

  The light emitting element 202 is opposed to the light guide member 200 provided in the center actor 105. When the light emitting element 202 emits light, the light is received from the light receiving surface 200B of the light guide member 200, and the light guide member The inside of 200 is guided and output from the light emitting surface 200A.

  In other words, the center accessory 105 of the present embodiment can provide an electric decoration effect by a combination of reflected light by so-called metal skin plating and light from the light emitting element 202. The board 18 is placed and attached to the set board 206 which is separated from the center accessory device 105, and the grounding process is perfect. The electric wiring board 208 has a structure in which electrical breakdown does not occur even if there is accumulation and subsequent discharge.

(Outline of game specifications)
First, game control centering on lottery processing on the main control board 150 will be described.

  When the game ball PB wins the special symbol start winning opening (A) 129 or the special symbol start winning opening (B) 134, the main control board 150 determines whether or not it is an effective start winning prize. The effective start winning is that the holding ball is full (for example, a new starting winning ball that is newly added when the LCD display unit 106 is in a symbol variation state upon detection of the first start winning number for one start opening. 4), it means that the game ball PB has won the special symbol start winning port (A) 129 or the special symbol start winning port (B) 134, thereby obtaining the lottery right. In the invalid starting prize, the right to draw is not given, but a predetermined number (about 3 to 5) of prize balls may be paid out. The valid start prize has the right of special symbol lottery, and the invalid start prize has no right of special symbol lottery.

  When the start prize is an effective start prize, the main control board 150 obtains a random number for winning lottery according to the winning timing from a random number generator (not shown), and uses a pre-stored winning value. Read and compare both to determine whether the special symbol lottery is a hit or miss.

  If the current gaming state is in jackpot processing or symbol variation pattern production, in order to put the special symbol lottery right on hold, the holding number is incremented by one (+1), and the current gaming state is jackpot processing When it is not in the middle or when the symbol variation pattern production is no longer being performed, the special symbol lottery process is executed by subtracting the number of holdings by one.

  Based on the winning / losing of the special symbol lottery, the symbol variation pattern effect time is set, and a command including the special symbol lottery result and the symbol variation pattern time is sent to the effect control board 152.

  The effect control board 152 controls output system devices such as the LCD display unit 106 and the speaker 60 to notify the result of the special symbol lottery using the set effect time. For example, on the LCD display unit 106, a symbol variation pattern effect is executed.

  After this notification, if the result of the special symbol lottery is a win, a special game (a jackpot process) is executed. In the normal game state, the closed attacker 112 is always opened and closed by a predetermined number of rounds (about 2R to 16R). The opening time of the attacker 112 is a maximum of 30 seconds. The attacker 112 is closed when a predetermined number (for example, 8 to 10) of game balls are won during the opening, and a predetermined closing time is set. , Go to the next round (open). Thereby, the player can receive a lot of prize balls in a short time. As one of the game specifications, the opening time of the attacker 112 is, for example, about 0.9 seconds, and the number of times of opening and closing is 2R, and a subsequent privilege (probability change etc.) is received without receiving a substantial prize ball. There are only cases.

  Here, although not directly related to the game specifications as described above, for example, a center accessory 105 is attached around the LCD display unit 106 to enhance the interest of the game, and the design decoration thereof. It is carried out. As this design decoration, the surface is subjected to chrome plating, and the decoration effect is improved by reflection of ambient light.

  Moreover, in this Embodiment, in addition to the said design decoration effect, the effect by the electrical decoration using light is performed.

  Here, in FIG. 8, as a comparison with the present embodiment, a comparative example of a configuration for effect by electrical decoration of the accessory device is shown.

  In this comparative example, a chrome plating layer 302 is provided on the surface of the decorative member 300, a concave portion 304 is formed in a part thereof, and a lens portion 306 is attached. An electrical wiring board 308 is attached to the back surface side of the decorative member 300, and a light source part 310 is attached to face the recessed part 304.

  In this case, the decorative member 300 (the chrome plating layer 302) has static electricity accumulation due to the contact with the game ball PB, and when this is discharged, the electronic components of the electric wiring board 308 may be destroyed, or , May cause runaway phenomenon of electronic circuits.

  For this reason, a metal plate 312 (for example, a reinforcing metal plate) is provided on the back surface side of the electric wiring board 308, and the electric wiring board 308, In addition, the decorative member 300 (chrome plating layer 302) is fastened together. Further, one end of a ground wire 316 is attached to the screw 314, whereby the electric wiring board 308 including the decorative member 300 is all grounded.

  However, in the joint fastening using the screws 314 as described above, the number of parts is increased and the joint fastening work of three or more parts is performed, so that the assembly workability is poor.

  On the other hand, in the center actor 105 of the present embodiment, as shown in FIGS. 6 and 7, the combination of the reflected light from the metal skin plating process (chrome plating layer 210) and the light from the light emitting element 202. The lighting effect can be brought about. In this case, the light emitting element 202 is disposed in a physically and electrically non-contact state with the game board 18 in between, and is attached to the set board 206 that is separated from the center accessory device 105, and the grounding process is performed. Therefore, even if there is an accumulation of static electricity mainly from the chromium plating layer of the center accessory 105 and subsequent discharge, the electrical wiring board 208 will not be electrically damaged.

  That is, in the present embodiment, the number of parts is reduced and the assembly workability is improved by the following different configurations as compared with the structure of the comparative example.

  (Structure 1) The electric wiring board 208 to which the light emitting element 202 was attached was attached to the set board 206 which was disposed on the back side of the game board 18 and was grounded in advance, and subjected to conduction treatment.

  (Configuration 2) A streaky light guide member 200 is provided on the center accessory 105.

  (Configuration 3) The surface of the decorative member 204 that comes into contact with the light guide member 200 is mirror finished (chrome plated layer 210) simultaneously with the decorative surface.

  (Configuration 4) Light from the light emitting element 202 is guided from the light emitting surface 200A of the light guide member 200 by guiding the light from the light emitting element 202 to the light receiving surface 200B of the light guide member 200 in an electrically and physically non-contact state.

  For this reason, in the center accessory 105, the variation of the illumination effect can be increased by the harmony between the light reflected by the mirror-finished surface and the light emitted from the light emitting element 202 via the light guide member 200.

  In addition, the game ball PB comes into contact with the center actor 105, static electricity is accumulated in the chrome plating layer 210 that is mirror-finished in particular, and the electric wiring board 208 to which the light emitting element 202 is attached is located at a position sandwiching the game board 18. Therefore, even if the accumulated static electricity is discharged, the discharge noise does not affect the electric wiring board 208 and the like. In other words, since it is not necessary to perform the grounding process on the center accessory 105 itself, the assembling workability can be improved.

  In the present embodiment, the game ball PB is a source of static electricity, but static electricity is likely to be generated by sliding a metal member such as a medal of a pachislot machine. For this reason, this embodiment arrange | positions a light source (electrical wiring board) in the state which is physically and electrically non-contact with respect to the decoration member containing an electrical decoration effect | action, via the light guide member 200 The configuration in which light is received from a remote location and emitted from the light guide member 200 can also be applied to other gaming machines such as a pachislot machine.
