Description

  The present invention relates to gaming machines such as pachinko machines and pachislot machines.

  In general, a gaming machine such as a pachinko machine or a pachislot machine is provided with an operation unit on the front side for accepting a player's operation.

As the operation unit, Patent Document 1 discloses a switch device that stops the rotation of a reel of a slot machine (pachislot).
This switch device includes an elliptical stop button, a switch case that houses the stop button, and a substrate on which a light emitting diode and a photosensor are provided. The stop button includes a push button member formed of a cylindrical lid that forms an operation surface for performing a switch operation, and an inner tube that is fitted to the push button member. An insertion hole for accommodating the light emitting diode is provided at the bottom of the inner cylinder, and the light emitting diode is disposed inside the stop button. A strip-shaped light shielding piece extends from the end of the side surface of the inner cylinder. The board is fitted in the switch case.
Further, in this switch device, the player is notified of the operation timing of the stop button by the internal light emitting diode illuminating the push button member. When the stop button is pressed by the player and the stop button moves in the switch case, the photo sensor detects the movement of the light shielding piece and stops the rotation of the reel.

JP-A-8-298042

  However, in the switch device described in Patent Document 1, an insertion hole into which the light emitting diode is inserted is provided at the center of the bottom portion of the inner cylinder, and the light shielding piece extends from the side surface of the inner cylinder. For this reason, a difference occurs in the amount of movement of the light shielding piece according to the pressed portion of the push button member. That is, when the side of the push button member that opposes the light shielding piece is pressed, the amount of movement of the light shielding piece increases. When the side of the push button member that opposes the light shielding piece is pressed, the movement of the light shielding piece is increased. The amount becomes smaller. For this reason, even if the player presses the push button member with the same force, depending on the pressed part, the movement amount of the light shielding piece is small and the photo sensor cannot detect the movement of the light shielding piece, and the rotation of the reel is not stopped. There is. Therefore, there is a possibility that the operation intended by the player cannot be detected.

  In order to reduce the fluctuation of the movement amount of the light shielding piece according to the pressed location, for example, it is conceivable to provide the light shielding piece near the center of the bottom of the inner cylinder. However, in this case, there is a possibility that the photosensor that detects the movement of the light shielding piece is irradiated with the light of the light emitting diode leaking from the insertion hole, and the photosensor cannot accurately detect the movement of the light shielding piece. Therefore, there is a possibility that the operation intended by the player cannot be detected.

  Therefore, in order to prevent the light leaking from the insertion hole from being irradiated to the photosensor, it is conceivable to provide an insertion hole into which the light emitting diode is inserted other than the central portion at the bottom of the inner cylinder. However, in this case, the light emitting diodes arranged in the inner cylinder are not arranged in the vicinity of the central axis of the inner cylinder, and the push button member cannot be illuminated uniformly. For this reason, there is a possibility that the player cannot recognize that the push button member is shining.

  Accordingly, an object of the present invention is to provide a gaming machine that can uniformly illuminate a member pressed by a player and can accurately detect an operation intended by the player.

  In order to achieve the above object, a gaming machine of the present invention includes an operation unit that receives an operation of a player. The operation unit includes a pressing body, a storage unit, and a substrate.

The pressing body is a hollow member that moves when pressed by a player. An accommodating part accommodates a press body so that a movement is possible. The substrate is mounted with a light emitting portion that emits light inside the pressing body and an optical sensor that detects the movement of the pressing body, and is housed in the housing portion.
The pressing body is formed in a cylindrical shape and has a cylindrical portion with a through-hole formed on the side surface, a pressing portion that blocks one opening in the cylindrical hole of the cylindrical portion, and is pressed by the player, and faces the pressing portion. And a projecting portion projecting along the central axis of the cylindrical portion from the vicinity of the central portion on the surface opposite to the surface facing the pressing portion of the opposing portion, the opposing portion closing the other opening in the cylindrical hole of the cylindrical portion, Have The optical sensor detects the movement of the pressing body by detecting the movement of the protruding portion, and the light emitting portion is disposed in the vicinity of the central axis of the cylindrical portion in the cylindrical hole of the cylindrical portion via the through hole.

In the above configuration, the protruding portion protrudes along the central axis of the cylindrical portion from the vicinity of the central portion on the surface opposite to the surface facing the pressing portion of the facing portion.
For this reason, the fluctuation | variation of the movement amount of the protrusion part according to the press location of a press part can be made small. Therefore, the optical sensor can accurately detect the movement of the protruding portion regardless of the pressed portion of the pressing portion of the player. Thereby, the operation intended by the player can be detected with high accuracy.

The opposing portion closes the other opening of the cylindrical hole of the cylindrical portion, and the protruding portion protrudes along the central axis of the cylindrical portion from the vicinity of the central portion on the surface opposite to the surface facing the pressing portion of the opposing portion.
For this reason, it can prevent that the light of a light emission part irradiates the optical sensor which detects the movement of a protrusion part. Therefore, the operation intended by the player can be detected with high accuracy.

Further, the light emitting part is disposed in the vicinity of the central axis of the cylindrical part in the cylindrical hole of the cylindrical part via the through hole.
For this reason, a press part can be made to shine uniformly by the light irradiated from a light emission part.

  According to the present invention, a member pressed by a player can be uniformly illuminated, and an operation intended by the player can be detected with high accuracy.

Various productions are performed.

  When the start lever is operated, an effect random number value (hereinafter referred to as effect random number value) is extracted in addition to 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 content of the production is determined, the production execution means is linked to each opportunity such as when the rotation of the reel is started, when the rotation of each reel is stopped, or when the presence / absence of a prize is determined. To proceed with the production. This effect executing means is carried out by a sub-control circuit described later. In this way, in the pachislot, the player is given the opportunity to know or predict the determined internal winning combination (in other words, the combination of symbols to be aimed at) by executing the production contents associated with the internal winning combination. As a result, the player's interest is improved.

<Main control circuit>
Next, the main control circuit 91 constituted by the main control board 71 will be described with reference to FIG.
FIG. 8 is a block diagram illustrating a configuration example of the main control circuit 91 of the pachi-slot 1.

  The main control circuit 91 includes a microcomputer 92 installed on the main control board 71 as a main component. The microcomputer 92 includes a main CPU 93, a main ROM 94, and a main RAM 95.

  The main ROM 94 stores a control program executed by the main CPU 93, a data table, data for transmitting various control commands (commands) to the sub control circuit 101, and the like. The main RAM 95 is provided with a storage area for storing various data such as an internal winning combination determined by execution of the control program.

  The main CPU 93 is connected to a clock pulse generation circuit 96, a frequency divider 97, a random number generator 98, and a sampling circuit 99. 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.

  As described above, in the present embodiment, the maximum number of sliding symbols is set to four symbols. Therefore, when the stop button 19L is pressed, the symbol of the reel 3L in the middle of the reel display window 4 and each symbol within the range up to the four symbols ahead can be stopped in the middle of the reel display window 4. It becomes a simple design.

  Further, when the photosensor 420 of the stop switch substrate 400 outputs a high level signal, the main CPU 93 outputs a lighting signal that instructs lighting to the LED 410 of the stop switch substrate 400. On the other hand, when the photo sensor 420 outputs a low level signal (pressing detection signal), the main CPU transmits a turn-off signal that instructs turning off to the LED 410 of the stop switch substrate 400.

<Sub control circuit>

Also included are a storage area for storing sound data related to BGM and sound effects, a storage area for storing lamp data related to the light on / off pattern, and the like.

  The sub-RAM 103 is provided with a storage area for registering the determined contents and effects data, and a storage area for storing various data such as an internal winning combination transmitted from the main control circuit 91.

  The sub CPU 102, the rendering processor 104, the drawing RAM (including the frame buffer) 105, and the driver 106 create a video according to the animation data designated by the content of the presentation, and display the created video on the liquid crystal display device 11.

  Further, the sub CPU 102 causes a sound such as BGM to be output from a speaker such as speakers 58, 64, 65L, and 65R in accordance with the sound data specified by the contents of the effect. Further, the sub CPU 102 controls the turning on and off of the light source such as the LED 85 in accordance with the lamp data designated by the contents of the effect.

Next, the operation of the present embodiment will be described with reference to FIGS.
FIG. 22 is a cross-sectional view taken along line B-B in a state where the stop button 19 of the operation unit 15 in FIG. 10 is pressed.

  When the LED 410 on the stop switch substrate 400 of the operation unit 15 receives the lighting signal output from the main CPU 93, the light emitting unit 411 of the LED 410 emits light.

As shown in FIG. 20, the light emitting part 411 of the LED 410 is located near the central axis X of the small cylinder part 203 in the cylinder part 200 of the stop button 19. Further, the opening behind the stop button 19 is sealed by a sealing portion 206, and a coating material having a high reflectance is applied to the front surfaces of the vertical portion 207 and the inclined portion 208 in the sealing portion 206. For this reason, the light of LED410 is reflected efficiently and irradiated ahead.
The light irradiated forward is diffused by the light diffusion film 230, and the pressing surface portion 221 of the pressing portion 220 of the stop button 19 is uniformly irradiated.

  As shown in FIG. 22, when the pressing portion 220 is pressed and the stop button 19 moves rearward, the protruding portion 210 is interposed between the light emitting diode 421 and the photodiode 422 of the photosensor 420. Then, the protrusion 210 blocks the light of the light emitting diode 421 irradiated to the photodiode 422. At this time, since the sealing portion 206 blocks the light of the LED 410 that is irradiated backward, the photosensor 420 is not irradiated with the light of the LED 410. For this reason, the amount of light received by the photodiode 422 becomes less than the predetermined light amount, and the photosensor 420 outputs a low level signal (pressing detection signal). The main CPU 93 outputs a turn-off signal based on a low level signal (pressing detection signal). Then, the LED 410 is turned off according to the turn-off signal.

  Further, when the pressing portion 220 is pressed and the stop button 19 moves backward by a predetermined distance, the rear surface of the connecting portion 204 of the cylindrical portion 200 comes into contact with the front surface of the step portion 316 of the concave portion 313 in the front member 310 of the housing portion 300. . For this reason, the stop button 19 is restricted from moving further backward.

  In the present embodiment, the protruding portion 210 of the stop button 19 protrudes from the vicinity of the central portion on the rear surface of the sealing portion 206 along the central axis X of the cylindrical portion 200, so that it corresponds to the pressed portion of the pressing portion 220. Variations in the amount of movement of the protrusion 210 can be reduced. For this reason, the photosensor 420 can accurately detect the movement of the protrusion 210 that accompanies the pressing of the pressing part 220, that is, the movement of the stop button 19, regardless of the pressing location of the pressing part 220 of the player. For this reason, the operation intended by the player can be accurately detected.

  Further, since the sealing portion 206 blocks the light of the LED 410 that is irradiated rearward and the light of the LED 410 is not irradiated to the photosensor 420, the photosensor 420 can detect the movement of the stop button 19 with high accuracy. For this reason, the operation intended by the player can be accurately detected.

Further, the light emitting portion 411 of the LED 410 is disposed in the vicinity of the central axis X of the small tube portion 203 of the tube portion 200 in the tube hole of the tube portion 200 through the through hole 209 of the tube portion 200.
For this reason, the pressing surface portion 221 of the pressing portion 220 can be illuminated uniformly by the light emitted from the light emitting portion 411.
