The reel driver means 108 is based on the position sensor 49 and the ball output rate setting means 119. Then, a pulse for controlling the rotation driving of the reel 6 is transmitted and input, and the ball output rate setting means 11
9 inputs the winning rate to the winning detection means 120.

As a result, the winning detection means 120 is selected by the winning rate probability selection means 119 by the player based on the pulse of the reel driver means 108, the memory 121 and the position sensor 49, and is selected by the discharge rate setting means 119. The arrangement of the symbols 18 is controlled by rotating the reel motor 39 so as to conform to the above-mentioned ball exit rate.

The pitch-out rate setting means 119 is adapted to set the pitch-out rate, which was set by adjusting the nails in the well-known pachinko machine, by an electric signal. The case of setting the rate will be described.

A plurality of types of ball exit rates (for example, 50%, 8
0%, 88% to 115%, 120%, etc.), and divide this random number table data into a winning area, a specific winning area, and a non-winning area according to the rate of the ball.
The division pattern is stored in the memory (not shown) of the ball output rate setting means 119.

Then, by operating a switch (not shown) provided in the ball output rate setting means 119, a pattern is selected.

Thereby, the rate-of-ball-out setting means 119 sets the rate of ball-out, and the winning detection means 120 controls the reel driver means 108 according to this setting. Therefore, when the stopping means 25 is activated, the reel driver means 108 adjusts the winning probability and the ball-out rate by delaying the speed attenuation of the reel 6 or the like.

The game selection means 28 is provided with a memory 122, and the memory 122 has a procedure of a general game and a procedure different from the procedure of the general game, and wins from the one selected by the probability selection means 26. High probability of at least 1
The specific game of the species is stored.

As a result, the game selection means 28 is a winning detection means.
Based on the winning of the specific winning detection signal from 120, the specific game is selected and executed, in other cases, the general game is selected and executed.

Further, the game selection means 28 transmits a signal (including a non-prize detection signal) corresponding to the procedure of the specific game or the general game to the procedure display means 23, and the game selected and executed by the game selection means 28 is shown. The signal is transmitted to the game display means 27.

The procedure display means 23 causes the game progress operation panel 22 to emit light based on a signal corresponding to the procedure of the specific game or the general game from the game selection means 28, and sequentially displays the operation procedure of the game to the player. It is for.

Next, the ball detection sensor 73 turns on the probability selecting means 26 according to the number of inserted pachinko balls, so that the player selects the desired probability selecting means 26. As a result, the probability display means 16 illuminates and displays only the selected array line 20,
At the same time, the other array line 20 is turned off.

Then, only the selected array line 20 is illuminated and displayed, at the same time, the other array lines 20 are extinguished and the game starting means 24 is illuminated and displayed. When the player further closes the game starting means 24, the game starting means 24 and the probability selecting means 26 are turned off, the reels start rotating and the stopping means 25 is turned on.

Each time the player closes the game starting means 24, the stopping means 25 is turned off, and at the same time, the reel 6 is stopped.
At this time, if it is in the winning state, the line symbol 21 blinks to display the winning.

When the player makes a mistake in selecting the array line 20 before closing the game starting means 24, the initialization means 65 is used.
The probability selection means 26 is returned to the state before selection of the array line 20 by the operation of, and the line symbol 21 (array line 20) is turned off via the probability display means 16.

Subsequently, the procedure display means 23 measures the stable running time required by the predetermined reel motor 39 by means of a timer (not shown), and then lights the stop means 25. As a result, the player closes the stopping means 25 to stop the reel 6.

If the stopping means 25 is not operated until the predetermined time elapses even after the stable running time has passed, the reel 6 is stopped by the stopping means 25 as is well known.
Is stopped, and one of the symbols 18 is stopped and displayed through the display window 17.

Next, the winning detection means 120 is the position sensor 49,
Based on the reel driver means 108 and the memory 121, it is detected whether or not there is a winning. When the detected content is not a winning, the general game is ended and the pachinko ball is waited for.

When the detected content is a prize, the prize detecting means 120 detects whether or not it is a specific prize, and activates the sprocket driver means 114 according to the content of the prize to pay out a prize ball.

Subsequently, when the winning is a specific winning, the winning detecting means 120 transmits a detection signal corresponding to the specific winning to the game selecting means 28.

Next, the game selection means 28 selects a specific game by the memory 122, and at the same time, transmits a signal corresponding to the selection of the specific game to the game display means 27 and the procedure display means 23.

As a result, the specific game is started, and the procedure display means 23 sequentially displays the operation procedure of the specific game by the game progress operation panel until the specific game is finished. After the specific game is over, the game returns to the normal game (initial state) and waits for the insertion of a pachinko ball. Thereby, the player can understand the game procedure by the procedure display means.
