  In the pachislot machine of the present embodiment, medals are used as game media for playing games. In addition to the medals, coins, game balls, game point data, tokens, or the like can be applied as game media.

  When a player inserts a medal and operates the start lever, one value (hereinafter, random number value) is extracted from random numbers in a predetermined numerical range (for example, 0 to 65535).

  The internal lottery means performs lottery based on the extracted random number value and determines an internal winning combination. This internal lottery means is carried out by a main control circuit described later. By determining the internal winning combination, a combination of symbols that permits display along a winning determination line described later is determined. The types of symbol combinations include those related to “winning” in which benefits such as paying out medals, re-games, bonuses, etc. are given to players, and other so-called “loses”. Is provided.

  Further, when the start lever is operated, a plurality of reels are rotated. Thereafter, when the player presses the stop button corresponding to the predetermined reel, the reel stop control means performs control to stop the rotation of the corresponding reel based on the internal winning combination and the timing when the stop button is pressed. Do. The reel stop control means is responsible for a main control circuit described later.

  In the pachislot machine, basically, control is performed to stop the rotation of the corresponding reel within a specified time (190 msec or 75 msec) from when the stop button is pressed. In the present embodiment, the number of symbols that move with the rotation of the reel within the specified time is referred to as “the number of sliding symbols”. When the specified time is 190 msec, the maximum number of sliding symbols is set to 4 symbols, and when the specified time is 75 msec, the maximum number of sliding symbols is set to 1 symbol.

  When the internal winning combination allowing the symbol combination display related to winning is determined, the reel stop control means usually displays the symbol combination within the specified time of 190 msec (four symbols) for the winning determination line. The rotation of the reel is stopped so as to display as much as possible. In addition, the reel stop control means is defined for one or more reels when, for example, a challenge bonus (CB), which is a second-type special accessory, and a middle bonus (MB) for continuously operating the CB are operated. The reel rotation is stopped so that the combination of symbols is displayed as much as possible along the winning determination line within a time of 75 msec (for one symbol). Furthermore, the reel stop control means uses various specified times corresponding to the gaming state to rotate the reels so that combinations of symbols that are not permitted to be displayed by the internal winning combination are not displayed along the winning determination line. Stop.

  Thus, when the rotation of the plurality of reels is all stopped, the winning determination means determines whether or not the combination of symbols displayed along the winning determination line is related to winning. This winning determination means is carried out by a main control circuit described later. When it is determined by the winning determination means that it is related to winning, a privilege such as paying out medals is given to the player. In a pachislot machine, a series of flows as described above is performed as one game.

  Also, in the pachislot machine, in the above-described series of flows, video display performed by an image display device such as a liquid crystal display device, light output performed by various lamps, sound output performed by a speaker, and shutter driving by a shutter device. Alternatively, various effects are performed using these combinations.

  When the start lever is operated, an effect random number value (hereinafter referred to as effect random number value) is extracted separately from the random number value used for determining the internal winning combination. When the effect random number value is extracted, the effect content determining means determines, by lottery, what is to be executed this time from among a plurality of types of effect contents associated with the internal winning combination. This effect content determination means is carried out by a sub-control circuit described later.

  When the contents of the effect are determined, the effect executing means executes the corresponding effect in conjunction with each opportunity, such as when the rotation of the reels starts, when the rotation of each reel stops, or when determining whether there is a winning. As described above, in the pachislot machine, the player has an opportunity to know or predict the determined internal winning combination (in other words, a combination of symbols to be aimed at) by executing the production contents associated with the internal winning combination. The player's interest can be improved.

The clock pulse generation circuit 96 and the frequency divider 97 generate clock pulses. The main CPU 93 executes a control program based on the generated clock pulse. The random number generator 98 generates a random number in a predetermined range (for example, 0 to 65535). The sampling circuit 99 extracts one value from the generated random numbers.

  The main CPU 93 counts the number of times pulses are output to the stepping motors of the reels 3L, 3C, 3R after detecting the reel index. Thereby, the main CPU 93 manages the rotation angle of each reel 3L, 3C, 3R (mainly, how many symbols the reel has rotated).

  The reel index is information indicating that the reel has made one revolution. This reel index is provided at a predetermined position of each of the reels 3L, 3C, 3R, for example, with a light emitting unit and a light receiving unit, and between the light emitting unit and the light receiving unit by the rotation of each reel 3L, 3C, 3R. Detection is performed by a reel position detection unit (not shown) including a detection piece interposed therebetween.

  Here, the management of the rotation angle of each reel 3L, 3C, 3R will be specifically described. The number of pulses output to the stepping motor is counted by a pulse counter provided in the main RAM 95. Each time the output of a predetermined number of pulses (for example, 16 times) necessary for the rotation of one symbol is counted by the pulse counter, the symbol counter provided in the main RAM 95 is incremented by one. The symbol counter is provided for each reel 3L, 3C, 3R. The value of the symbol counter is cleared when a reel index is detected by a reel position detector (not shown).

  In other words, in the present embodiment, by managing the symbol counter, it is possible to manage how many symbols have been rotated since the reel index was detected. Therefore, the position of each symbol on each reel 3L, 3C, 3R is detected with reference to the position where the reel index is detected.

  In the present embodiment, the maximum number of sliding symbols is basically set to 4 symbols. Therefore, when the left stop button 17L is pressed, the symbol of the left reel 3L in the middle of the display window 4 and each symbol within the range up to four symbols ahead can be stopped in the middle of the display window 4. It becomes a simple design.

  As shown in FIGS. 20 and 26, the rotation mechanism 230 configured as described above drives the engagement member 234 to rotate 180 ° by moving the rack portion 233 in the vertical direction by driving the drive motor 231. In addition, as shown in FIG. 24, the engagement member 234 can be rotated by a predetermined drive amount by driving the drive motor 231 by a predetermined number of steps.

  Accordingly, the rotation mechanism 230 rotates the engagement member 234 in the forward and reverse directions by 180 ° by driving the drive motor 231, so that the surfaces 201 a, 202 a, 203 a, and 204 a of the shutter members 201, 202, 203, and 204 are The shutter members 201, 202, 203, and 204 can be rotated at the shielding position so that the back surfaces 201b, 202b, 203b, and 204b are reversed.

  Further, the rotation mechanism 230 rotates the engagement member 234 by a predetermined drive amount (for example, 90 °) by driving the drive motor 231, so that the surfaces 201 a, 202 a, 203 a, and 204 a of the shutter members 201, 202, 203, 204 are The shutter members 201, 202, 203, 204 can be stopped at an angle 204a orthogonal to the image display surface 11a (see FIG. 23).

  Next, referring to FIG. 27, the cross-sectional shape of the shutter members 201, 202, 203, 204 will be described using the shutter members 201, 202 as an example. The other shutter members have the same cross-sectional shape, and thus the description thereof is omitted.

  As shown in FIG. 27, the shutter member 201 has one end portion 301 positioned above the short side direction and a short side when the surface 201a is parallel to the image display surface 11a (see FIG. 14). And the other end 302 located below the direction. Similarly, the other shutter members 202 to 204 have one end 301 and the other end 302.

  The one end portion 301 and the other end portion 302 have a cross-sectional shape in a direction orthogonal to the rotation axis direction of the shutter member 201 (a direction orthogonal to the paper surface in FIG. In FIG. 27, the shape has vertices 301a and 302a separated from each other in the left-right direction indicated by arrow J.

  Specifically, the cross-sectional shape of the one end portion 301 is a shape having an inclined portion 301b inclined from the front surface 201a side toward the apex 301a located on the back surface 201b side from the center in the J direction of the shutter member 201. For this reason, the inclined portion 301b occupies an area of half or more of the thickness of the shutter member 201 in the J direction at the one end portion 301.

  On the other hand, the cross-sectional shape of the other end portion 302 is a shape having an inclined portion 302b inclined from the back surface 201b side toward the apex 302a located on the front surface 201a side rather than the apex 301a. Further, the vertex 302a is located closer to the back surface 201b than the center of the shutter member 201 in the J direction. For this reason, the inclined portion 302b stays in the region of the other end portion 302 that is less than or equal to half the thickness of the shutter member 201 in the J direction.

  Therefore, when the shutter member 201 is pushed upward, the apex 301a of the shutter member 201 moves upward along the inclined portion 302b of the shutter member 202, so that the shutter member 202 becomes H as shown in FIG. Rotate in the direction. Thereafter, the inclined portion 301b of the shutter member 201 moves upward along the back surface 202b of the shutter member 202, whereby the shutter member 202 further rotates in the H direction.

  Note that the cross-sectional shapes of the one end portion 301 and the other end portion 302 shown in this embodiment are merely examples, and any shape can be used as long as the shutter member 202 can be rotated by raising the shutter member 201. It may be a shape.

  Next, a structure for causing the shutter members 201, 202, 203, and 204 to emit light will be described with reference to FIGS.

  As illustrated in FIG. 28, the shutter device 200 includes a light irradiation device 400 as a light irradiation unit that irradiates light to the shutter members 201, 202, 203, and 204 from the side. Two are provided at both ends in the longitudinal direction. Moreover, these light irradiation apparatuses 400 are being fixed to the side piece parts 222 and 223 of the shutter base 220 via the support member 400a, respectively.

  The light irradiation device 400 includes four LEDs 401, 402, 403, and 404 arranged in the vertical direction corresponding to the shutter members 201, 202, 203, and 204, respectively. The LEDs 401, 402, 403, and 404 are included in the LED group 25 (see FIG. 3) described above.

  Further, the shutter members 201, 202, 203, and 204 are provided with a decoration 500 on at least a part of one surface (in this embodiment, the back surfaces 201b to 204b). The decoration 500 is drawn in an arbitrary shape, and is not particularly limited to the shape shown in FIG.

  As shown in FIG. 29, the light irradiated from the LEDs 401, 402, 403, and 404 is reflected toward the front side of the pachislot machine 1 (see FIG. 2) at the places where the decorations 500 of the back surfaces 201b to 204b are applied. The unevenness 501 to be formed is formed.

  As shown in FIG. 30, the unevenness 501 has an inclined surface 501 a that allows the light emitted from the LEDs 401, 402, 403, and 404 to be reflected toward the front side of the pachislot machine 1 as indicated by arrows in the drawing. . In FIG. 30, the unevenness 501 provided on the back surface 202b of the shutter member 202 has been described as an example, but the unevenness 501 of the other shutter members is also configured similarly.

  Moreover, in this Embodiment, LED401,402,403,404 is installed in the light irradiation apparatus 400 in the inclined state so that light may be irradiated with respect to the inclined surface 501a of the unevenness | corrugation 501 at a predetermined angle. Here, the installation angles of the LEDs 401, 402, 403, and 404 are angles at which the inclined surface 501 a can be irradiated with irradiation light such that the light reflected by the inclined surface 501 a is directed to the front surface side of the pachislot machine 1. More precisely, the installation angle of the LEDs 401, 402, 403, 404 and the angle of the inclined surface 501a are set in consideration of the incident angle and the reflection angle of the LEDs 401, 402, 403, 404 with respect to the inclined surface 501a. preferable.

  As described above, the pachislot machine 1 according to the present embodiment is provided with the shutter device 200 having the shutter members 201 to 204 that can be moved up and down on the front side of the pachislot machine 1 with respect to the liquid crystal display device 11. The lowermost shutter member 201 is moved up and down by the lifting unit 206, while the other shutter members 202 to 204 connected to the lowermost shutter member 201 via the slider mechanism 210 are the lowermost shutter members. It moves up and down in conjunction with 201.

  Thereby, the pachislot machine 1 which concerns on this Embodiment can combine the image effect by the liquid crystal display device 11, and the accessory effect by the raising / lowering of the shutter member 201 as a visual effect. Therefore, the pachislot machine 1 according to the present embodiment can improve the interest of the game by performing a visual presentation rich in surprise.

  In addition, the pachislot machine 1 according to the present embodiment can move all the shutter members 201 to 204 in conjunction with each other only by moving the lowermost shutter member 201 up and down. For this reason, it is not necessary to provide lifting means corresponding to all the shutter members 201 to 204, and the shutter device 200 can be configured with a simple configuration.

  Further, in the pachislot machine 1 according to the present embodiment, the shutter members 201 to 204 are rotated in one rotational direction by the torsion spring 262 so that the surfaces 201a to 204a of the shutter members 201 to 204 are parallel to the image display surface 11a. Since it is urged | biased (the direction shown by arrow G in Fig.15 (a)), the rattling at the time of the shutter members 201-204 raising / lowering can be suppressed. Thereby, the pachislot machine 1 concerning this Embodiment can perform raising / lowering of the shutter members 201-204 smoothly.

  Further, in the pachislot machine 1 according to the present embodiment, all the shutter members 201 to 204 raised to the exposure positions (positions shown in FIG. 17) are rotated so that the respective surfaces 201a to 204a face upward. And are accommodated in the space on the back side of the upper exterior member 7a. For this reason, when all the shutter members 201 to 204 are accommodated, the shutter members 201 to 204 can be hidden on the back side of the upper exterior member 7a that is not visually recognized by the player. Thereby, when the shutter members 201 to 204 are lowered, it is possible to give an unexpectedness to the player.

  Further, in the pachi-slot machine 1 according to the present embodiment, the shutter members 201 to 204 have the front surface 201a to 204a and the back surface 201b to 204b as the engaging member 234 is rotationally driven by the drive motor 231 of the rotation mechanism 230. Is rotated at the shielding position (position shown in FIG. 19) so as to be reversed. For this reason, not only the liquid crystal display device 11 is simply shielded by the shutter members 201 to 204, but the movements of the shutter members 201 to 204 are made by reversing the front surfaces 201 a to 204 a and the back surfaces 201 b to 204 b of the shutter members 201 to 204. It can be surprising.

  Further, in the pachislot machine 1 according to the present embodiment, the shutter members 201 to 204 are configured such that the surfaces 201a to 204a stop at an angle orthogonal to the image display surface 11a. The image display surface 11a can be made visible to the player also at the position indicated by 19). Thus, the movement of the shutter members 201 to 204 can be made more surprising, and an effect that combines the shutter members 201 to 204 and the liquid crystal display device 11 can be performed even at the shielding position.

  In the pachislot machine 1 according to the present embodiment, the cross-sectional shapes of the one end 301 and the other end 302 of the shutter members 201 to 204 are separated from each other in the direction perpendicular to the surfaces 201a to 204a of the shutter members 201 to 204. The shape has the vertices 301a and 302a. For this reason, when the shutter members 201 to 204 are raised, one end portion 301 of the lower shutter member comes into contact with the other end portion 302 of the upper shutter member, thereby causing the upper shutter member to be biased by the torsion spring 262. It can be easily rotated.

  Further, the pachislot machine 1 according to the present embodiment has the inclined portions 301b and 302b inclined toward the apexes 301a and 302a where the one end 301 and the other end 302 of the shutter members 201 to 204 are separated from each other. The upper shutter member can be smoothly rotated by the contact between the inclined portion 301b of the one end portion 301 of the lower shutter member and the inclined portion 302b of the other end portion 302 of the upper shutter member.

  Further, in the pachislot machine 1 according to the present embodiment, light is irradiated to the shutter members 201 to 204 from the light irradiation device 400 provided on the side of the shutter members 201 to 204. Moreover, the unevenness | corrugation 501 which reflects the irradiated light toward the front side of the pachislot machine 1 is formed in the place where the decoration of the back surface 201b-204b of the shutter members 201-204 was given. Thereby, it is possible to irradiate light to the shutter members 201 to 204 as the movable accessory in a limited space and to allow the player to recognize the reflected light.

  In addition, since it is possible to give the player a feeling as if the decorated part is emitting light by the reflection of light by the projections and depressions 501, there is no need to provide a light emitting portion on the shutter member itself, and the parts cost and manufacturing are reduced. Cost can be reduced.

  Further, in order to make the decoration of the shutter members 201 to 204 stand out, it is only necessary to form the unevenness 501 only on the decorated part, so that the decoration design can be easily changed.

  In the pachi-slot machine 1 according to the present embodiment, the unevenness 501 on the back surfaces 201b to 204b of the shutter members 201 to 204 has an inclined surface 501a that can reflect the irradiated light toward the front side of the pachi-slot machine 1. The light emitted from the light irradiation device 400 can be reliably reflected toward the front side of the pachislot machine 1.
