As for the symbols 29 (for example, alphabetic characters) of the symbol drum 19, the symbol centers are formed at the same interval in units of a plurality of frames (for example, 18 frames) with the index 58 as a reference position, and are arranged in an appropriate order. You. For example, in the case where the symbols 29 are formed and arranged in units of 18 frames, the value of the random number counter for determining the symbol to be stopped of the symbol drum 19 is determined based on the position where the index 58 matches the detection means 31 as a reference “0” value. , "0-1
7 ”is set. The counter value is reset every time the motor 17 and the symbol drum 19 rotate once.

The above-described design drums 19 in all rows are
An example is a thermal transfer method in which the symbol display portion printed on the film base material is thermally transferred to the outer periphery of the cylinder portion 42, and the symbol 29 is painted and arranged. For each of the symbols 29, two or more colors of ink (e.g., red, yellow, yellow-green, pink, blue, etc.) that can be preferably illuminated and illuminated with respect to the ultraviolet light radiated from the illumination device 33 are used. Printed with a fluorescent ink) is preferably used. However, the surrounding base portion except for each symbol 29 is printed with another single-color normal ink (other than the light-emitting ink) in which all the symbols are satisfactorily illuminated, so that the entire symbol display surface has a large number of colors.

As described above, in each symbol unit U composed of one drive base 11 unit, the motor 17
The design drum 19 is connected mainly by using a rotation transmission braking means 47 as exemplified in FIGS. That is, the stepping motor 17 has its seating plate 38 closely fitted in the circular hole 37 of the drive base 11 and is fixedly positioned with screws or the like, and the rotating disk with screw holes 41 connected to the inner end of the motor shaft 39 ( A rotating member 40 extends inward through the circular hole 37. On the other hand, the design drum 19
A thin-walled and lightweight boss 45 is integrally formed at the center of an arm 44 in the rim 42.
An engaging piece (one end) 46 for positioning and linking to the rotation transmitting braking means 47 is formed at a required position on the outer periphery of the left end portion of the fifth protrusion.

In the above-described configuration example of the motor 17 and the design drum 19, the rotation transmission braking means 47 has a configuration in which a rotation supporting cylinder 48 made of synthetic resin and a transmission braking member 55 are integrated. As shown mainly in FIGS. 5, 6 and 7, the rotary support tube 48 has a design drum 1
The first support cylinder 49A, which has a cylindrical cap shape with a flange and is inserted into the right cylindrical portion of the boss 45 of the ninth ninth and is connected to the rotary plate 40 of the motor 17, is positioned and inserted into the left cylindrical portion of the boss 45. A second support cylinder 49B having the same shape connected to the first support cylinder 49A;
A, 49B.
1, 51 are formed, and a plurality of screw holes 53, 53, an engaging convex portion 54a and an engaging concave portion 54b at the center are formed in the circular lid portions 52, 52. The transmission braking member 55 is formed integrally with the outer periphery of the opening end of the second support cylinder 49B to have a ring shape having a diameter larger than that of the flange 51. 5
The semi-circular connecting and locking pieces 57 on both sides separated from the first piece 1 are elastically deformable inward and outward, so that their free ends can be locked to the engagement pieces 46.

In such a rotation transmission braking means 47, in a normal state, the second support cylinder 49B is inserted into the left portion of the boss 45 of the design drum 19 to position the transmission braking member 55 on the engagement piece 46. On the other hand, the first support cylinder 49A is inserted into the right portion of the boss 45 and engaged with the second support cylinder 49B so that the engagement concave / convex portions 54a, 54b and the screw holes 53,
53 is maintained in a positioned state. In the manufacture of each symbol unit U, as for assembling of the symbol drum 19 with respect to the motor 17, the first support cylinder 49A is fitted to the turntable 40, and the respective screws are aligned from the second support cylinder 49B side. Screws are screwed into the holes 53 and 41 to be detachably assembled in a non-coupled state. The design drum 19 is moved relative to the rotation transmission braking means 47 directly connected to the motor 17.
Boss 45 and flanges 51, 51 of both support cylinders 49A, 49B
This prevents the axial vibration of the transmission braking member 55.
It can rotate and stop stably. In the rotary support cylinder 48, the two support cylinders 49A, 49B have the same-diameter cylindrical portions 50, 50 fitted in the boss 45 with a tolerance dimension. The locking piece 57 is slightly expanded to lightly and elastically hold the engaging piece 46.

As shown in FIG. 8, the basic electric control system of the variable symbol display device M is mainly composed of the control section of the electric control device E. That is, every time the start signal is generated by the switch of the start winning tool 10, when the start signal is input to the winning determination unit 75, the random number data setting unit 76 sets the driving conditions of the stepping motors 17 of each row and the driving of the design drum 19. One piece of random number data (any one of a miss and a big hit) for determining a stop symbol is set. Based on this random number data,
The motors 17 in each row are sequentially driven under the set conditions (time and speed) according to the respective pulse outputs sent from the motor control unit 77, and the symbol drum 19 rotates and fluctuates. Thereafter, when the motors 17 and the symbol drums 19 in each row are sequentially stopped, the index 3 for each detecting means 31 is determined.
Based on the stop position of No. 2, each counter section 79 sets each set pulse number as a counter value for one frame of the symbol “0 to 0”.
17 "and input to each symbol detection unit 80. Then, each symbol detection unit 80 detects and determines a stop symbol in each column on each pay line 5 on the perspective display 1 side based on each counter value, and inputs the detection signal to the win determination unit 75. Finally, the winning determination unit 75 individually or entirely determines the combination state of the respective stop symbols based on the input order of the detection signals.

As a result, in the combination of the stop symbols on each of the winning lines 5, when all the rows have the same kind of match, it is determined as “hit”, and in the other left and right rows, the middle row is made with the same kind of match. In the case of non-coincidence of, all of them are determined to be "out". By the way, at the time of the start input, at the time of symbol change and at the end, and further, at the time of predetermined symbol combination condition, a sound effect from a speaker (see FIG. 8) provided in the main body of the pachinko machine, the lamps 38 and 39, and The effect light by the lighting fixtures 33 in each row is generated respectively.

The basic symbol variation control according to the symbol variable display device M described above, that is, the rotation control of the stepping motor 17 and the symbol drum 19 in the symbol display units U in each row are illustrated in the time chart of FIG. The summary is set as follows. (A) When the power is turned on, three rows are started simultaneously or sequentially, and after the speed is increased while the speed is increased, the "missing symbol combination" is stopped and displayed on the winning line 5 while being decelerated. The stop symbol in each row is confirmed as the origin position before the start by the index 32 for the detection means 31. Thus, the initial display condition of the device M is set. (b) Regarding the start of the symbol change by the start input, the left row, the middle row, and the right row are started simultaneously or sequentially with a predetermined time difference,
Based on one data selected from the random number data setting unit 76, the speed is changed to a predetermined high speed while being stepwise increased in a continuous fluctuation process over a set time. However, the three rows of high-speed fluctuations include different symbol matching times. (c) As for the symbol fluctuation stop by the stop input, the stop is performed at a predetermined time difference while being gradually decelerated from a high speed in a left column, a right column, and a middle column in order. (d) Regarding the fluctuating time (from start to stop) of each column, the left column, right column, and middle column are “T ₁ , T ₂ , T ₃ ” at the time of “out”
Is a, the left column when "hit" in the right column common time-varying only middle row is changed to "T _3" appropriately longer than the "T _4, T _5".

[0024]

Next, the operation of the variable symbol display device according to the embodiment will be described. Note that the display device M mainly develops a symbol combination game based on a start input resulting from a game ball being detected by the start winning device 10 during a game on the pachinko machine. An example of the variation control mode will be described below with reference to FIGS.

In other words, in the apparatus M, the combination state of "missing symbols" in the symbol drums 19 of each row is stopped and displayed on each of the winning lines 5 under the above-described initial display condition after the power is turned on. The origin position of the symbol is confirmed based on the position (count value) of the index 32 with respect to the column detecting means 31. In this state, the starting prize 1
When the winning detection signal of the switch of 0 is input to the winning determining unit 75 of the electric control device E, one data (either out of or hit) relating to the stop symbol in the drum in each row is output from the random number data setting unit 76. It is randomly extracted and temporarily stored in the winning determination unit 75. Then, based on the random number data, the fluctuation conditions of the motor 17 and the symbol drum 19 in each row
(Time) is set. Note that a sound effect A is generated at the time of the start winning.

On the premise that the motor 17 and the symbol drum 19 in each row are controlled under the rotational fluctuation conditions set based on the above-mentioned random number data, the left row, the middle row, The right column is sequentially started at every predetermined time difference, and is changed at high speed while being temporarily increased in speed.
Then, during this change, after a stop input corresponding to the random number data is received after a set time, the left and right columns are changed based on a change in symbol matching according to any of “missing and hitting”. , The middle row is sequentially decelerated and stopped at predetermined time intervals. In this fluctuation process, in the electric control device E, each counter 79 sets the position of the index 32 with respect to the detecting means 31 of each column to the counter value “0 to 17” based on the set pulse output number for one frame symbol. The counter value of the 192 pulse 18-frame design is reset as a "0" point each time both 31 and 32 match. Note that the effect sound B and the effect light a are generated from the start to the end of the fluctuation of each row drum.

Regarding the above-described symbol fluctuation stop, first, when the random number data is "out of order", the motor 17 and the symbol drum 19 in each row are stopped and fluctuated based on the set time (T ₁ , T ₂ , T ₃ ). Based on the premise, symbols of different types are stopped and displayed on the respective pay lines 5. In response to this stop, the respective counter units 79 set the counter values “0 to 17” based on the position of the index 32 with respect to the detecting means 31 in each column.
Is detected, and the data is transmitted to the symbol detecting unit 80. The detecting unit 80 detects a stopped symbol and transmits the information to the winning determination unit 75. Finally, in the winning determination unit 75, the random number data "out of place" at the time of the start input and the detection data "out of place" from the symbol detection unit 80 are confirmed, and the combination of the symbols stopped and displayed is "out of place". "
Is determined. At the time of "disengagement", the sound effect C and the effect light a are generated in connection with the stop of each row design drum 19.

When the random number data is "hit", the motor 17 and the symbol drum 19 in each row are set for the set time (T ₁ ,
_On the premise that the fluctuation is stopped based on T ₂ , T ₄ or T ₅ ), the symbols (matching) of the same kind in the left, right and middle rows are stopped and displayed on the respective winning lines 5. In response to the stop, count detection data and symbol detection information are transmitted from the counters 79 and the symbol detection units 80 based on the position of the index 32 with respect to the detection means 31 in each column. The random number data at the time and the symbol detection data are confirmed, and it is determined that the combination of symbols is "hit". At the time of the "hit", the left drum 1
9, the sound effect C and the effect light a are generated, and thereafter, a required time before the stop of the right row drum 19, for example, from a point immediately before the N symbols to a stop point of the right row drum 19 and the middle row drum 19. , A sound effect D (also referred to as a reach sound) is generated, and the effect light is also changed to a blinking effect light b (also referred to as a reach blinking light). After the middle drum 19 stops, a sound effect E (also referred to as a hit sound) and a flashing effect light by simultaneous synchronization (also referred to as a hit flashing light) are generated.

In the symbol variable display device M of the present embodiment configured and set as described above, in the symbol variation control operation of the symbol unit U of each example, the motor 1 that is pulse-driven is controlled.
By appropriately controlling the rotation and stop of the symbol drum 19 with respect to the symbol 7, a stable fluctuation stop display of the symbol drum 19 can be presented. That is, the boss 45 of the symbol drum 19
The rotation transmission braking means 47, which is inserted into the rotation disk 40 of the motor 17 and is always stopped by the flanges 51, 51 of both the support cylinders 49A, 49B of the rotation support cylinder 48, suppresses the rotation runout, and also transmits the transmission braking. The two connecting and locking pieces 57 of the member 55 are elastically engaged with both sides of the engaging piece 46. In this case, the symbol drum 19 is rotated in the direction of the arrow in FIG.
Looking at the speed-up process from the start of driving of the motor 17 to the high speed, the design drum 19 that rises and rotates with respect to the speed-up rotation of the rotation transmission braking means 47 is one of the transmission braking members 55 (the right side in FIG. 6). ) While being stopped by the linking piece 57, the rotation is accelerated while following the transmission force from the other linking piece 57 (left side in FIG. 6). Looking at the process of the motor 17 from a high speed to a low speed and stopping, the design drum 19 having the inertia at the high speed stage with respect to the deceleration rotation of the rotation transmission braking means 47 has one (the right side in FIG. 6). Linking locking piece 5
7, while receiving the braking force, the rotation force is reduced by the transmission force from the other (left side in FIG. 6) linking piece 57, and with the stop of the motor 17 and the means 47,
The design drum 19 is immediately stopped by braking.

As described above, the transmission force and the braking force are maintained while the symbol drums 19 in the symbol units U of each row are elastically engaged and held by the transmission braking member 55 of the rotation transmission braking means 47 from two circumferential directions. The rotation following the rotation support cylinder 48 while receiving the rotation of the design drum 19, the swing in the front and rear direction of rotation, which is apt to occur particularly in the rising process and the stopping process of the design drum 19, that is, the fluctuation including forward rotation and return is positively suppressed. And is suitably solved. As a result, the symbol drum 19 can smoothly rotate to exhibit a stable symbol variation that has a favorable impression on the player, and is quickly stopped by the stop of the motor 17 and the rotation transmission braking means 47. The symbol 29 can be stopped and displayed on the winning line 5,
It is possible to present an accurate combination display of symbols.
