Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine such as a pachinko gaming machine or a slot machine, and more particularly to a gaming machine that displays a moving image in a display area of a display device.

[0002]

2. Description of the Related Art Conventionally, in a gaming machine such as a pachinko gaming machine, a liquid crystal display device (LCD: Liquid Crystal Displa).
On the variable display device such as y), variable display of a plurality of types of identification information (special symbols) prepared in advance is performed, and it is determined whether or not a predetermined game value is given based on the display result, so-called variable display. Many games are offered that enhance the fun of the game.

As a variable display game, there is a variable display game (special figure game) mainly using an image display device as the variable display device. In the special figure game, the special symbol is variably displayed in accordance with the detection of the game ball passing through the predetermined area, and the derived display mode when the display result of the special symbol is derived and displayed is the specific display mode. It is a game of "big hit". When the "big hit" occurs in the special drawing game, a special electric prized object called a special winning opening is operated to open the special winning opening door. As a result, the player is continuously provided with a state in which winning of the game ball is extremely easy for a certain period of time.

In such a gaming machine, a variable display of special symbols is executed by a moving image display, a moving image display is performed as one of the effect displays in a special figure game, and an effect display during a big hit and a demonstration display. Some of them display moving images.

When displaying a moving image, moving image data is stored in the ROM mounted on the gaming machine, the moving image reproducing LSI mounted on the gaming machine reads the moving image data from the ROM, and the read moving image is read. It is common to perform moving image reproduction based on data. In general, in order to reduce the amount of data, the ROM stores the compressed (encoded) moving image data, and the LS for moving image reproduction is used.
I performs decompression processing (decoding processing) on the compressed video data to obtain a reproduced video.

As a data compression method for moving image data,
An inter-frame predictive coding method such as an MPEG (Motion Picture Coding Experts Group) method is often used. In the interframe predictive coding method, the frame (1
Motion compensation predictive coding that encodes the difference between the image signal (image data) of the screen) and the predicted image signal is used, and the encoded data is compressed into moving image data (hereinafter,
It is called compressed data. ). The predicted image signal is obtained by motion compensation prediction. Motion-compensated prediction includes forward prediction (forward prediction) in which a predicted image signal is obtained only based on a past image signal, and bidirectional prediction in which a predicted image signal is obtained also using a future image signal. Compressed data based on forward prediction is called a P picture, and one frame of compressed data by a P picture is called a P frame. Also, compressed data based on bidirectional prediction is called a B picture, and one frame of compressed data by a B picture is called a B frame.

When performing the decoding process, the predicted image signal must already be obtained. Therefore, in an image stream in which frames are continuous (hereinafter, simply referred to as a stream), an I frame is set by intra-frame coding (intra-frame coding) that does not use a predicted image signal. The I frame is a frame based on an I picture obtained by encoding the image signal itself.
A frame is compressed data that can be restored to the original image signal by decoding without using other data such as a predicted image signal. I-frames are not only initially set in the stream, but also inserted as appropriate.

[0008]

Although the amount of data stored in the ROM can be reduced by using the data compression as described above, when the interframe predictive coding method is used, reverse reproduction (stream It is not possible to decode and reproduce each data-compressed image signal in (3) in the reverse direction.

In a gaming machine such as a pachinko gaming machine, it may be desired to perform reverse reproduction in order to enrich the effect. For example,
This is a case where the special symbol is variably displayed in the reverse direction, or the background or character displayed on the image display device is displayed as a moving image in a time reverse to the normal moving image display. However,
As described above, such an effect cannot be performed when the inter-frame predictive coding method is used. In addition,
I-frames that are appropriately inserted in the stream are data that can be independently reproduced. Therefore, if the I-frames in the stream are sequentially decoded in the backward direction, fast-forward reverse reproduction can be performed. The effect will be reduced.

The present invention has been made in view of the above problems, and an object of the present invention is to perform reverse reproduction of a moving image while maintaining the effect of reducing the amount of data stored in the storage means for reproducing a moving image. It is to provide a gaming machine that enables the game.

Next, the operation of the gaming machine will be described. Figure 6
Is a flowchart showing main processing executed by the game control means (CPU 33 and peripheral circuits such as ROM and RAM) on the main board 30. When the power of the gaming machine is turned on and the input level of the reset terminal becomes high level, the CPU 33 starts the main processing after step S1. In the main process, the CPU 33 first makes necessary initial settings.

In the initial setting process, the CPU 33 first sets the interrupt prohibition (step S1). Next, the interrupt mode is set to interrupt mode 2 (step S
2) The stack pointer designated address is set in the stack pointer (step S3). Then, the built-in device register is initialized (step S4). After initializing the CTC (counter / timer circuit) and PIO (parallel input / output port) that are built-in devices (built-in peripheral circuits) (step S5), the RAM is set to the accessible state (step S6). . In the interrupt mode 2, the address composed of the value (1 byte) of the specific register (I register) built in the CPU 33 and the interrupt vector (1 byte: least significant bit 0) output by the built-in device is the interrupt address. This is the mode shown.

Next, the CPU 33 confirms whether or not the clear switch provided in the gaming machine is on (step S7). When ON is detected in the confirmation, the CPU 33 executes normal initialization processing (step S10 to step S12). If the clear switch is not in the ON state, whether or not the data protection processing of the backup RAM area (for example, processing when power supply is stopped such as addition of parity data) is performed when the power supply to the gaming machine is stopped. Confirm (step S8). After confirming that such protection is not performed, C
The PU 33 executes an initialization process. Backup RAM
Whether or not there is backup data in the area is confirmed by, for example, the state of the backup flag set in the backup RAM area in the power supply stop process.

After confirming that there is a backup, the CPU3
3, the game state recovery processing for returning the internal state of the game control means and the control state of the electric component control means such as the effect control means to the state at the time of stopping the power supply (step S9). Then, the saved value of the PC (program counter) saved in the backup RAM area is set in the PC and the address is restored.

In the initialization process, the CPU 33 first reads R
AM clear processing is performed (step S10). Further, a predetermined work area (for example, a random number counter for normal symbol determination, a normal symbol determination buffer, a special symbol left middle right symbol buffer,
Special symbol process flag, payout command storage pointer,
A work area setting process for setting an initial value to a flag in the prize ball, a flag out of the ball, a payout stop flag, and the like for selectively performing a process according to the control state is performed. Further, a process of transmitting an initialization command for initializing the sub-board (production control board 100, payout control board 40) to the sub-board is executed (step S11). As an initialization command, a command indicating an initial symbol displayed on the variable display device 6,
There is a payable state designation command indicating that the payable state is available.

Then, the register of the CTC built in the CPU 33 is set so that a timer interrupt is periodically applied every 2 ms (step S12). That is, a value corresponding to 2 ms as an initial value is set in a predetermined register (time constant register).

Execution of initialization processing (steps S10 to S1)
When 2) is completed, the display random number updating process (step S14) and the initial value random number updating process (step S15) are repeatedly executed in the main process. When the display random number updating process and the initial value random number updating process are executed, the interrupt disabled state is set (step S13), and when the display random number updating process and the initial value random number updating process are completed, the interrupt enabled state is set. (Step S16). The display random number is a random number for determining the symbol displayed on the variable display device 6, and the display random number updating process is a process of updating the count value of the counter for generating the display random number. . The initial value random number updating process is a process of updating the count value of the counter for generating the initial value random numbers. The initial value random number is a random number for determining an initial value such as a counter (big hit determination random number generation counter) for generating a random number for determining whether or not to make a big hit. In the game control process described later, when the count value of the big hit determination random number generation counter makes one round, the initial value is set to the counter.

When a timer interrupt occurs, the CPU 33
After performing the register saving process (step S20), executes the game control process of steps S21 to S32 shown in FIG. In the game control process, first, the CPU 33, via the switch circuit 58, the gate switch 12
a, a starting opening switch 7a, a count switch 23, a winning opening switch 16a, etc.
The state determination is performed (switch processing: step S2
1).

Next, a process of updating the count value of the counter for generating the initial value random number and a process of updating the counter value for generating the display random number are performed (steps S23 and S24). The CPU 33 further
A process of updating the count value of the counter for generating the display random number is performed (step S24).

In this example, a big hit determination random number used for determining whether or not to generate a big hit, a random number for deviating symbol determination used for determining a deviating symbol on the left, middle, and right of a special symbol, when generating a big hit. Random number for determining big hit symbols used when determining the combination of special symbols, random number for determining fluctuation patterns used for determining variation patterns of special symbols, normal Ordinary used for determining whether to generate a hit based on symbols Various random numbers such as a random number for determining a symbol, a random number for determining an initial value used for determining an initial value of each random number, and the like are prepared.

In step S23, the CPU 33 counts up (adds 1) the counter for generating the big hit determining random number, the big hit symbol determining random number, and the normal symbol hit determining random number. That is, those are judgment random numbers, and the other random numbers are display random numbers or initial value random numbers.

Further, the CPU 33 carries out special symbol process processing (step S25). In the special symbol process control, the corresponding process is selected and executed according to the special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to the gaming state. Then, the value of the special symbol process flag is updated during each process according to the game state. Also, a normal symbol process process is performed (step S26). In the normal symbol process process, the corresponding process is selected and executed according to the normal symbol process flag for controlling the display state of the normal symbol display device 14 in a predetermined order. Then, the value of the normal symbol process flag is updated during each process according to the game state.

Next, the CPU 33 performs a process of setting the effect control command relating to the special symbol in a predetermined area of the RAM 55 and transmitting the effect control command (special symbol command control process: step S27). In addition, the production control command regarding the normal design is set to the specified territory of RAM32, the processing which sends the production control command is done (normal design command control processing: step S28).

Further, the CPU 33 supplies, for example, jackpot information, start information, which is supplied to the hall management computer,
Information output processing for outputting data such as probability variation information is performed (step S29).

Further, the CPU 33 executes the prize ball processing for setting the number of prize balls based on the detection signals of the winning opening switches 16a, 17a, 18a and 19a (step S30). Specifically, the winning opening switch 16
In response to the winning detection based on any one of a, 17a, 18a, and 19a being turned on, a payout control command indicating the number of prize balls is output to the payout control board 40. Discharge control board 4
The payout control CPU mounted on the No. 0 drives the ball payout device according to a payout control command indicating the number of prize balls.

Then, the CPU 33 executes a storage process for checking the increase / decrease in the number of memory for winning the winning prize (step S3).
1). Further, when a predetermined condition is satisfied, a drive command is issued to the solenoid circuit (step S32). The variable winning ball device 9 or the opening / closing plate 11 is opened or closed,
In order to switch the game ball passage in the special winning opening 10, the solenoid circuit provided in the main board 30 drives the solenoids 9a, 11a, 12a according to the drive command. After that, the contents of the register are restored (step S33),
The interrupt enabled state is set (step S34).

According to the above control, in this embodiment, the game control process is activated every 2 ms.
In this embodiment, the game control process is executed in the timer interrupt process, but in the timer interrupt process, for example, only a flag indicating that an interrupt has occurred is set, and the game control process is executed in the main process. It may be done.

In this embodiment, the symbols "1" to "12" are variably displayed (changed) on the variable display device 6 as the left symbol, the middle symbol and the right symbol.
The symbol numbers 0 to 11 are attached to the symbols "1" to "12". In addition, a big hit occurs when the final stop symbols (determined symbols) on the variable display device 6 are aligned. And, when the odd-numbered symbols are aligned, the high-probability state (probability change state) is a state in which the probability of a big hit is improved.
Changes to.

Further, in this embodiment, information transmission such as an instruction from the game control means to each electric component control means is performed.
Control command (production control command, payout control command)
Done by The control command has, for example, a 2-byte structure, and the first byte is MODE (command classification).
The second byte represents EXT (command type). The effect control means mounted on the effect control board 100 detects that the INT signal (acquisition signal) has risen, and performs 1-byte data (MODE) by interrupt processing.
(Data) fetching process is started, and the subsequent interruption process starts fetching 1-byte data (EXT data).

Next, the operation of the effect control means will be described. FIG. 8 is a flowchart showing a main process executed by the effect control CPU 101. In the main process, first, R
Initialization processing is performed for clearing the AM area, setting various initial values, and initializing a 2 ms timer for determining the activation interval of effect control (step S701).
After that, the effect control CPU 101 shifts to the loop processing for checking the timer interrupt flag (step S702). When a timer interrupt occurs, C for production control
The PU 101 sets a timer interrupt flag in the interrupt processing process. In the main process, if the timer interrupt flag is set, the effect control CPU 101
The flag is cleared (step S703), and the following effect control processing is executed.

In this embodiment, the timer interrupt is 2 m.
It takes every s. That is, the effect control process is activated every 2 ms. In addition, in this embodiment, only the flag is set in the timer interrupt process, and the specific effect control process is executed in the main process, but the effect control process may be executed in the timer interrupt process.

In the effect control processing, the effect control CPU
101, first, analyzes the received effect control command (command analysis execution process: step S704). Next, the effect control CPU 101 performs effect control process processing (step S705). In the production control process processing,
A process corresponding to the current control state is selected and executed from the processes according to the control state. Then, a process of updating various random number counters used in the effect control board 100 is executed (step S706). Further, the moving image decoding control process (step S707), which is a process for causing the moving image expansion unit 89 to start the moving image expansion process, is executed. After that, the process returns to the process of confirming the timer interrupt flag in step S702.

Here, reception of the effect control command from the main board 30 will be described. The effect control board 100 includes a command reception buffer for storing the effect control command received from the main board 30. For example, a command receiving buffer in the ring buffer format that can store six 2-byte effect control commands is used. The effect control means is controlled based on the latest command stored in the storage area of the variation pattern and the like. Thereby, the main substrate 3
You can quickly respond to instructions from 0. The effect control CPU 101 is interrupted when the INT signal from the main board 30 is turned on, executes a process for receiving the effect control command, and stores the received effect control command in the command reception buffer.

Then, the contents of the command stored in the received command buffer are processed by the command analysis process (step S
In step 704), processing such as setting a flag corresponding to the received command is performed. For example, if the received command in the command receiving buffer is a symbol designating command that designates the left middle right symbol, the data that can identify the designated symbol contained in the command is stored in the stop symbol storage area,
Set the corresponding valid flag. Further, for example, if the received command in the command reception buffer is a variation pattern command that specifies an effect pattern, data that can identify the variation pattern included in the command is stored in the variation pattern storage area, and the variation pattern reception flag is stored. Set.

FIG. 9 is a flowchart showing the effect control process process (step S705) in the main process shown in FIG. In the production control process process, steps S800 to S are performed according to the value of the display control process flag.
Any one of 806 is performed. In each process, the following process is executed.

Fluctuating pattern command reception waiting process (step S800): It is confirmed whether or not an effect control command (changing pattern command) capable of specifying the varying time is received. Specifically, it is confirmed whether or not a flag (fluctuation pattern reception flag) indicating that the fluctuation pattern command has been received is set. The fluctuation pattern reception flag is set when it is confirmed in the command analysis process that the effect control command designating the fluctuation pattern is received.
If the variation pattern reception flag is set, the value of the display control process flag is set to a value corresponding to the reach advance notice process.

Reach advance notice processing (step S801): Determines whether or not to perform a reach advance notice effect, and determines the contents of the reach advance notice effect when the reach advance notice is decided. When determined, the value of the display control process flag is set to a value corresponding to the all symbol variation start process.

All symbol variation start processing (step S80
2): Control is performed so that the fluctuation of the left middle right pattern is started.
Then, the value of the display control process flag is set to a value corresponding to the symbol variation process.

Processing during symbol fluctuation (step S803): The switching timing of each fluctuation state (fluctuation speed) forming the fluctuation pattern is controlled, and the end of the fluctuation time is monitored. In addition, stop control of the left and right symbols is performed. When the process is completed, the value of the display control process flag is set to a value corresponding to the all symbol stop waiting process.

All symbol stop waiting setting process (step S80)
4): At the end of the variation time, if a production control command instructing to stop all the symbols is received, the variation of the symbols is stopped and the control for displaying the stopped symbol (determined symbol) is performed. Then, when the big hit display mode is set, the value of the display control process flag is set to a value corresponding to the big hit display process, and when the big hit display mode is set, the value of the display control process flag is set to a value corresponding to the variable pattern command reception waiting process. To do.

Big hit display processing (step S805): After the end of the variation time, the probability variation big hit display or the normal big hit display is controlled. When the display period ends, the value of the display control process flag is set to a value corresponding to the big hit game process.

Processing during the big hit game (step S806):
Control the big hit game. For example, when the effect control command of the display before opening the special winning opening or the display when opening the special winning opening is received, display control of the number of rounds and the like are performed. When the control during the big hit game is finished, the value of the display control process flag is set to a value corresponding to the variable pattern command reception waiting process.

FIG. 10 is an explanatory diagram showing a configuration example of process data set for each variation pattern table. The process data is composed of data in which a plurality of combinations of the process timer set value and the effect control execution table are collected. In each production control execution table, display control execution data in which each variation mode that constitutes a variation pattern of display control of the variable display production 9 and the like, and variation pattern of display control of lamps / LEDs and the like are configured, respectively. The lamp control execution data in which each variation mode is described and the sound control execution data in which each variation mode that constitutes the variation pattern of the voice output control of the speaker 27 and the like are described are included. Further, the process timer set value is set with the change time in the change mode. Performance control CPU1
Reference numeral 01 refers to the process data, and displays the symbols in a changing manner set in the effect control execution table only for the time set in the process timer set value, turns on / off the light emitter, and the speaker 27. Control to output audio from.

The process data shown in FIG. 10 is stored in the ROM of the effect control board 100, and is set in the variation pattern table selected as the use table in the all symbol variation start process (step S802). Variable display device 6, lamp / LE based on data
Control of D24 and speaker 20L, 20R is started,
In the symbol changing process (step S803), control according to the control execution data is sequentially executed. The process data is prepared for each variation pattern.

Next, the operation of the moving picture expanding section 89 mounted on the effect control board 100 and the moving picture reproducing process will be described. As described above, the moving picture decompression unit 89 has a compressed data decoding function of an interframe predictive coding system such as the MPEG system. In other words, I frame, P frame, and B frame are used, and compressed moving image data using motion compensation prediction is used.

11 and 12 are explanatory views showing an example of a moving image displayed on the variable display device 6.
In the example shown in FIG. 11, when the left and right special symbols are stopped and displayed and the reach is established, characters such as two persons are displayed.
The operation is performed as if it affects the special symbol while continuing the variable display. Further, the sun and clouds are displayed on the background portion (a portion of the screen of the variable display device 6 excluding the display portion of the special symbol), and the display is performed as if the clouds were moving.

The CGROM 83 stores moving image data for realizing the moving image display illustrated in FIGS. 11 and 12. For example, if the frame frequency is 60 Hz and the reach effect is given for 5 seconds, moving image data for 300 frames is stored in the CGROM 83.
In that case, in the example shown in FIG. 11, n = 300. Then, as the stream A, moving image data of image 1 (corresponding to FIG. 11 (1)) to image n (corresponding to FIG. 11 (n)) is sequentially stored in the CGROM 83. Also, stream B
Image 1 ′ (corresponding to FIG. 12 (1 ′)) to image n ′
The moving image data (corresponding to FIG. 12 (n ′)) is CGR in order.
It is stored in the OM 83. The moving image data is already stored in the CGROM 83 when the game machine is shipped.

A feature of this embodiment is that moving image data of image n (corresponding to FIG. 11 (n)) to image 1 (corresponding to FIG. 11 (1)) is CGR in sequence as stream A.
That is stored in the OM 83. Therefore, the following effects can be easily executed.

That is, when the reach effect is performed after the reach is established and the stop symbol of the medium special symbol is a detached symbol (see FIG. 11 (n)), the image n to the image 1
The reverse reproduction of the moving image is performed toward, and the moving image as shown in FIG. 12 can be reproduced after the image shown in FIG. 11A is displayed on the variable display device 6. And
The big hit display as shown in FIG.

By carrying out such an effect, the player feels that he / she has hit the jackpot after the reach effect has been performed again by going back to the display state at the start of the reach effect, even though the player is once out of the way. It is possible to further enhance the interest of the game. Such an effect is to store the data-compressed moving image data of the stream A for the stream A in a configuration in which the moving image data compressed by the interframe predictive coding method is stored. It is the first production that can be realized by.

Here, the reach effect is taken as an example, but the present invention is not limited to the reach effect, and can be used in a variable display state before the reach is established or a display effect during a big hit game. That is, when it is desired to perform a reverse reproduction effect on a moving image reproduction based on a stream composed of a series of moving images, a stream (for example, stream A) in which the image data of each frame forming the stream is arranged in reverse is stored. By doing so, it is possible to realize reverse playback for arbitrary video playback.

Here, an example in which all the special symbols, characters and background images are displayed as a moving image is shown, but moving image display can also be applied only to a part of the screen of the variable display device 6. Also, the moving image reproduction may be always executed during a period when the display state is changed on the variable display device 6 (for example, during variable display of special symbols), or in a part of such a period. It may be configured to be executed only.

FIG. 13 is an explanatory diagram showing the data structure of each stream stored in the CGROM 83. Each stream has a file header set at the first address,
Subsequently, the frame header of each frame and the compressed data are sequentially set. Image 1 in stream A
~ The frame header and compressed data of image n (corresponding to (1) to (n) in Fig. 11) are set in order from image 1. In stream A, image n ~ image 1 (Fig. 11 (n) ~
The frame header (corresponding to (1)) and the compressed data are set in order from the image n. In stream B, image 1'-
The frame header and compressed data of the image n '(corresponding to (1') to (n ') in FIG. 12 are set in order from the image 1'.

Although three streams are illustrated in FIG. 13, the CGROM 82 actually stores a number of streams according to the type of moving image realized in the gaming machine.

Next, a method of decoding compressed data will be described with reference to the explanatory diagram of FIG. The frame numbers shown in FIG. 14A are serial numbers of the frames in each stream shown in FIG. 13 (frames 1 to N). And
The compressed data of frames 1 to N in each stream is
It is composed of I-frames, B-frames, or P-frames in the order shown in FIG. For example, frame 1 is an I frame, frames 2, 3, 5 and 6 are B frames, and frames 4 and 7 are P frames.
The subscripts attached to I, B, and P are serial numbers for each picture type.

As described above, in stream A, image 1
To n are set in order from the image 1 (see FIG. 14C),
In stream A, images n to 1 are set in order from image n (see FIG. 14D), and in stream B, images 1'to 1 '
n ′ are set in order from the image 1 ′ (FIG. 14 (E))
reference). Thus, for example, image 1 in stream A
Is an I frame, images 2, 3, 5 and 6 are B frames, and images 4 and 7 are P frames. Also, the image n in the stream A is an I frame, and the image n−
1, n-2, n-4, and n-5 are B frames, and the images n-3 and n-6 are P frames.

Note that the order of picture types is not always the same as in FIG.
4 (B) does not have to be the case. For example, 3 consecutive B frames, I frame and P without B frame
You may comprise a stream with a frame. In addition, in this embodiment, the number of frames of the stream B is set to be the same as the number of frames of the streams A and A in order to simplify the description. It is appropriately determined according to As described above, a stream of compressed moving image data includes one intra-coded frame data (I frame) and a plurality of forward predictive-coded frame data (P frames) for motion compensation. And compressed data in units of a plurality of bidirectionally encoded frame data (B frame) for motion compensation.

FIG. 15 is an explanatory diagram for explaining the decoding order of each frame. In the figure, is the frame setting order in the stream (storage order in the CGROM 83)
Indicates. As shown by, the moving picture expansion unit 89 first decodes a decodable I frame without referring to other frames to obtain the image data of the frame 1. Since the B frame is decoded by referring to both the previous frame and the subsequent frame in terms of time, the moving picture expansion unit 89 cannot decode the B frame at the stage when the image data of the frame 1 is obtained. Therefore, as indicated by, the P ₁ frame that is decoded with reference to the temporally previous frame is decoded _first . Then, as shown by, the B ₁ and B ₂ frames are decoded (the B ₂ frame is not shown). Similarly, as indicated by, P ₂ frame, B ₃ and B ₄ frame are decoded in this order (B ₄ frame is not shown). Therefore, the order of decoding is as shown by in FIG.

The moving picture expansion section 89 expands the image data of each frame obtained by decoding in the VRAM 84, but does not expand it in the decoding order, but the same order as the frame setting order in the stream (the order shown by). Therefore, in the VRAM 84, the images forming the moving image are sequentially set from the oldest to the newest.

Then, the GCL 81 realizes the moving image display on the variable display device 6 by sequentially outputting the images corresponding to the image data of each frame expanded in the VRAM 84 to the variable display device 6.

FIG. 16 is a flowchart showing a processing example of the moving picture decoding control processing (step S707) in the main processing shown in FIG. Performance control CPU 101
At the moving image generation timing (step S80
1), the processes of steps S802 to S805 are performed. Whether or not the moving image generation timing has come is, for example,
The determination is made based on the information set in the display control execution data after switching in the process data (see FIG. 10).

In step S802, the CPU for effect control
The 101 selects a stream to be used, and sets the head address in the CGROM 83 in which the stream to be used is stored in the stream setting register built in the moving picture decompression unit 89 (step S803). Also, VR
The address indicating the upper left image position in the AM 84 is set in the VRAM address setting register built in the moving picture expansion unit 89 (step S804). Then, an execution code determined as a code indicating the execution of the process is set in the execution register incorporated in the moving picture expansion unit 89 (step S805).

When the processing of steps S802 to S805 is performed, the moving picture expansion section 89 executes the decoding processing already described, and expands the image data obtained by decoding in the VRAM 84 as an image memory. The LSI as the moving picture decompression unit 89 used in this embodiment has a plurality of expansion modes. For example, an interrupt is generated when all the frames in the stream are decoded and the image data is expanded in the VRAM 84, an interrupt is generated each time the decoding process of one frame is completed, or a decoding process of several frames is completed. To generate an interrupt. Regardless of which expansion mode is used, the moving picture expansion unit 89 uses the CG
The compressed moving image data stored in the ROM 83 is decompressed, and the decompressed image data is VR-processed frame by frame in the reproduction order.
Deployed in AM84. Then, the GCL 81 as a moving image reproducing means performs desired moving image display by sequentially reproducing the image data expanded in the VRAM 84.

An interrupt signal based on the interrupt generated by the moving picture expansion unit 89 is input to, for example, an external interrupt terminal of the effect control CPU 101, and the effect control CPU 101 performs interrupt processing based on the interrupt for one frame, several frames or all frames. It is possible to know that the decoding process of is completed. If the interrupt is set to occur every frame or every few frames, the effect control CPU 10
1 causes the decoding process of the remaining frames to continue,
Again, the execution code is set in the execution register incorporated in the moving picture expansion unit 89. A different execution code is determined for each of the plurality of expansion modes, and the moving picture expansion unit 89 selects the expansion mode according to the set execution code.

As described above, the effect control means is
A moving image can also be handled as an image displayed on the variable display device 6, and compressed data (for example, stream A) by an interframe predictive coding method for realizing a moving image is stored and the moving image is also stored. Since compressed data (for example, stream A) for reverse reproduction is stored, it is possible to perform a moving image effect in which a moving image is displayed in a direction reverse to the moving image effect performed by the variable display device 6. It will be possible. That is, a part of the moving image reproduced by the moving image reproducing means includes an effect display in which the moving image being reproduced is reversely reproduced, and the moving image data when the reverse reproduction display is performed is reversed. Since the compressed moving image data is obtained by compressing the image data in frame units in the reproduction direction, it is possible to perform a moving image effect in which the moving image is displayed in the reverse direction.

In the above embodiment, as an example of the gaming machine, the variable display device 6 having both the function as the variable display device for variably displaying the identification information and the function as the image display device for displaying the effect image is provided. Although a pachinko gaming machine is used for the description, the present invention is not limited to a pachinko gaming machine, and the present invention can be applied to other gaming machines such as a slot machine provided with a variable display device and an image display device separately. Hereinafter, an example in which the present invention is applied to a slot machine which is an example of another gaming machine will be described.

Each gaming machine in each of the above-described embodiments is configured to give a predetermined gaming value to the player when the display result of the variable display on the variable display device becomes a predetermined specific display mode. It is said that. The game value is, for example, that a variable winning ball device provided in a game area of a game machine is in an advantageous state for a player who easily wins a prize, or a right to be in an advantageous state for a player is generated. Or the condition for paying out the prize game medium is easily established.

In the above embodiment, the "reach display state" means that the symbols other than the symbol that is the final stop symbol (for example, the middle symbol in the left and right middle symbols) in the variable display device continue for a predetermined time. , Display state that is stopped, swinging, enlarged or reduced or deformed in a state that matches the specific display mode, or a plurality of symbols fluctuates in synchronization with the same symbol, or the position of the display symbol is exchanged Then, it means a display state in which the possibility of a big hit continues before the final result is displayed. In addition, the production performed in the reach display state is called reach production. Further, the reach display state and the state thereof are referred to as a reach display mode.

The "specific game state" means a state that is advantageous to the player who is given a predetermined game value. Specifically, the "specific game state" is, for example, a state in which the state of the variable winning ball device is advantageous for a player who is easy to win a prize (big hit gaming state), and a right to be an advantageous state for the player is generated. A state in which a predetermined game value is given, such as a state or a state in which the condition for paying out the prize game medium is easily established.

Further, the "special game state" means a state that is advantageous to the player who is prone to a big hit. Specifically, the "special gaming state" is, for example, a probability variation state in which the probability that the special symbol is a big hit symbol and the probability of aligning is a high probability state, a time saving state in which the number of changes of the ordinary symbol per unit time is increased, a variable winning ball device 9 is a high-probability state in which the probability of a big hit, such as the opening period and the number of times of opening, is increased. In the time saving state, since the number of times the variable winning ball device 9 is opened is increased, the number of winnings per unit time is increased, and the number of times the special symbol is variably displayed per unit time is increased. Can be said to have been raised. Similarly, in the extended extension state, the number of winnings per unit time is increased because the opening period and the number of times of opening the variable winning ball device 9 are increased, and the number of times the special symbol is variable displayed per unit time is increased. Therefore, it can be said that the probability of being a big hit is increased.
