DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a symbol combination type.
More specifically, regarding a symbol variable display device for a pachinko gaming machine, when a combination game of a plurality of types of symbols is performed using a pachinko ball or a coin, when the combination winning condition of the symbols is established, it is advantageous for the player. The present invention relates to a drum type symbol variable display device implemented in a pachinko gaming machine capable of exhibiting a special gaming state.

[0002]

2. Description of the Related Art In a conventionally known pachinko machine or slot machine as a typical example of this kind of symbol combination pachinko game machine, a symbol combination game is executed based on fluctuation control conditions including start and stop each time. As a means for developing and displaying the winning combination condition which is a right relating to the special game state, a variable symbol display device which is generally called a drum type is employed. In this display device, even if there are differences in size, fluctuation control conditions, etc. depending on the target gaming machine, as a basic form, a flat pulley-shaped design drum formed of synthetic resin (a rotating body which is a base of the drum). For example, numbers,
Various kinds of symbols for identification such as alphabetic characters, other figures and marks are arranged), a stepping motor which is a direct rotation driving means of the drum, a position detection means and a lighting for each pattern which is stopped and displayed. It is made into a symbol display unit for each unit including means. The symbol display units are cascaded in a single housing frame with a plurality of units (normally, three units in a left column, a middle column, and a right column).

[0003] Such a symbol variable display device is used as a variation control mode for each symbol combination game.
(a) In a pachinko machine, a starting condition at the time when a game ball hit into the game surface is detected by a start winning device, an automatic stop signal generated from an electric control circuit device or a push button by a player in a timely manner. Any stop condition of the manual stop signal at the time of the operation of (b), in the slot machine, a start condition at the time of operation of the start means by the player after coin insertion, a stop condition at the time of operation of the stop means by the player, , The symbol drum is started to fluctuate in the set order and stopped in accordance with the drive control of the stepping motor for each row. Then, based on the symbol detection information obtained by the individual detecting means, based on the symbol matching information of each column stopped and displayed on the symbol combination line (also referred to as a winning line), a preset combination symbol (hit symbol) ), And the “hit / miss” is determined and controlled. In addition, under predetermined symbol combination conditions, each symbol is illuminated by the illumination means.

In this variable symbol display device, if the number of types of symbols and the number of frames are increased, and the size of each symbol is increased, the size of the symbol drum inevitably increases, and the size of the symbol drum increases. Since a motor is required, the entire display device is large and costly, resulting in a serious problem that cannot be suitably implemented.
For this reason, in reality, a pattern drum of a size (diameter) and weight corresponding to the performance of a usable stepping motor is implemented in a form that can be implemented in the gaming machine,
In connection with the limitation of the number of symbols of the symbol, etc., it has not been possible to sufficiently respond to the diversification of the display contents of the symbol combination game.

[0005]

By the way, in this type of design variable display device which has been used in the past, a normal design for a pachinko machine which is small and a slot machine which is large are usually used. The stepping motor used as a basic setting condition / item is driven and controlled in a predetermined step angle unit including a process of changing a pulse width and a time and increasing / decreasing a speed change, and the design drum has a plurality of outer ring-shaped rim portions. It is a flat pulley type in which the radial arms (mostly four or six) and the central boss are integrally molded with synthetic resin. However, with respect to the drum for the drive control of the motor, smooth and stable rotation / stop is difficult, and there is a problem that the design swings. That is,
Looking at the cause and condition of the drum rotation failure: (a) Due to the non-uniform mass of the entire drum in the radial direction, it is difficult for the drum to follow the rotation of the motor at the same time, The rising rotation (from the initial rotation to the speed-up rotation) is likely to be delayed. (b) Due to the non-uniform inertial force of the entire drum, the drum is likely to have a pitch-wise discontinuous rotation when the motor is being driven at a reduced speed or at a low speed. (c) Due to the non-uniform mass and inertial force of the entire drum, the drum is liable to cause rotational vibration with respect to driving of the motor. And, due to the rotation blur, it is difficult to accurately detect a symbol by the detector and the index. As a result, accurate detection stop display of symbols and combination games may not be maintained in some cases.

[0006]

SUMMARY OF THE INVENTION The present invention has been proposed to suitably solve the above-mentioned problems, and aims to smoothly and stably rotate and stop a symbol drum for driving control of a stepping motor to be used. It is an object of the present invention to provide a symbol variable display device for a symbol combination pachinko game machine which can maintain an accurate detection stop display and develop a suitable symbol combination game.

[0008]

The design drum is a circular rotating body in which a disk-shaped lid having a central boss is continuously connected to the inner periphery of an outer ring-shaped rim that forms a design surface by synthetic resin molding. The mass of the entire drum is made uniform in the radial direction from the center of rotation. Therefore, a smooth and stable rotation of the symbol drum with respect to the stepping motor can be obtained, and accurate symbol detection stop by the detector and the index can be achieved. In addition, by directly irradiating the symbols on the outer periphery of the rim portion with the lighting means, it is possible to enhance the lighting display effect according to the symbol combination game,
A light-shielding surface for source irradiation is formed on the surface of the lid.
Therefore, diffusion of light generated from the light source to the outside is suppressed.
Only the pattern is properly irradiated.

Further, as shown in FIG. 3, the see-through display plate 33 and the lens body 36 are formed in a forwardly protruding circular arc shape, and are aligned with each other in a front-rear spaced state.

As shown in FIG. 3, the housing box 41 is formed in a square shape with an open front, and is assembled and aligned on the back side of a holding frame 44 positioned and fixed to the back of the game board P. In the box 41, an accommodation room 42 for accommodating and setting each symbol display unit 45 is defined.
In addition, a relief hole 43 for a connector is opened in the rear plate portion of the box 41 corresponding to each unit 45 (see FIGS. 3 and 4). The holding frame body 44 is formed in a rectangular frame shape with front and rear surfaces opened, and is fixed directly to the back surface of the game board P while being positioned on the back side of the transparent body 31 described above.
The front opening is aligned with the lens body 36.

On the other hand, the three symbol display units 45 are:
As a basic configuration, as shown in FIG. 4, a drive base 46 having a vertically rectangular shape, a stepping motor 47 mounted on a center portion of the base 46 and controlled by pulse driving, and a symbol controlled by the motor 47 for rotation. It is composed of a drum 54 and the like. In the storage chamber 42 of the storage box 41, the symbol display units 45 are aligned and held at equal intervals while the drive base 46 is held in the positioning groove. In this set state, each unit 45 is configured such that the outer peripheral front portion of the symbol drum 54 protrudes from the front edge of the driving base 46 and the lens body 3 extends from the front opening of the holding frame body 44.

A detection tool 50 of the photoelectric sensor type and an illuminating means 51 for emitting ultraviolet light for directly illuminating the design from the inside at a predetermined position in the front portion are arranged, and a necessary drive control circuit 52 related to these electric components is arranged on the other side. (See FIG. 5). The boss portion 57 of the design drum 54 is connected to the rotating body 48 of the motor 47 in a state of covering the stepping motor 47 as shown in FIG.
It is rotated counterclockwise in FIG. During this rotation, each detector 50 is set to the corresponding index 58.
At the time when the light is shielded (described later), the detection (ON) state is set, and the individual motors 47 and the symbol drum 54 make one rotation (360 rotations).
°) is set to detect. However, as an example, each motor 47 makes one rotation in units of 192 pulses (36
0 °), and the angle is set to fluctuate by an angle of 22.5 ° for one symbol in units of 12 pulses.

As shown in FIGS. 4 and 5, the symbol display unit 45 in all rows has a required minimum width including the drive base 46 and the symbol drum 54. As shown in FIG. 3, the rotation center of each motor 47 and the symbol drum 54 and the detection center of the detection tool 50 pass through the horizontal line 35 on the side of the transparent body 31 with reference to the horizontal line 35. They are aligned at positions on the horizontal center line (XX). As the light source 51, two fluorescent lamps 51a and 51b each having a spherical head shape are used as light sources having different emission colors, and are directed to the lens body 36 so as to be vertically above and below a horizontal center line (XX). The symmetrical positions are arranged in a horizontal “eight-shaped” shape. And each fluorescent lamp 51a, 51b is different from each other
(E.g., blue light and red light) are set so that single color illumination switching control (color changing illumination control) can be performed one by one in response to predetermined symbol combination conditions.

On the other hand, each of the design drums 54 is formed into a circular cap shape as shown in FIG. It is a colored and transparent base color (for example, yellow) that can change color. A disk-shaped lid 56 having a boss 57 is connected to one side (right side in FIGS. 4 and 5) of the outer peripheral ring-shaped rim 55 having a constant smooth width. A single index 58, which serves as a reference index position of the symbol, is protruded inward in the radial direction. On the outer peripheral surface of the rim portion 55, various designs 59a and 59b, which will be described later, are painted and arranged by a thermal transfer method, and a light-shielding seal 60 for the light source of the illumination means 51 is provided on the outer surface of the lid portion 56 except for the boss portion 57. Is attached to the index 58, and a light-shielding surface for the detection tool 50 is formed on the index 58. The boss 57 is connected to the rotating body 48 of the motor 47 by a screw or the like. Note that the index 58 may be formed at a required position on the lid 56.

As shown in FIG. 6, with respect to each of the symbols in the three rows of the symbol drums 54, as shown in FIG.
Are unequally distributed, and 16 frames are sequentially arranged at unequal intervals. In the left and middle rows, the same type and the same number of symbols (symbols 59a to 59a for six frames and departure symbols 59b to 5 for ten frames)
9b) is unequally arranged by changing one type of release symbol 59b in the right column. And the three formation lines 35 on the side of the transparent body 31
As illustrated in FIG. 8, a case where three types of six types are set as “big hit symbol combination columns” that are stopped and displayed at a and 35b is illustrated. Incidentally, the numbers “0 to 15” in FIG. 6 mean the value of the random number counter that determines the stop symbol of the symbol drum 54 in each row, and the reference “the position where the index 58 matches the detector 50” is used as a reference. The counter value is reset every time the motor 47 and the symbol drum 54 rotate once.

The pattern drums 54 in all rows are formed by a film transfer method based on the thermal transfer method proposed in the invention "pattern painting method for game pattern drums" in Japanese Patent Application No. 4-47927 filed by the applicant. The symbol display portion printed on the base material is thermally transferred to the outer periphery of the rim portion 55, and the symbols 59a and 59b are arranged by painting. And each pattern 59a,
Regarding 59b, a color (for example, red,
Printing is performed using two or more colors of ink (also referred to as light-emitting ink or fluorescent ink) of yellow, yellow-green, peach, and blue. However, the underlying ground portion 59c excluding the symbols 59a and 59b is
All the symbols are printed with another single-color normal ink (other than the light-emitting ink) that looks good, and the entire symbol display surface is in a large number of colors.

The basic electric control system relating to the above-mentioned variable symbol display device D is mainly constituted by the control section of the electric control device E, as schematically shown in FIG. That is, every time a start signal is generated by the switch 5 of the start winning tool 4, when the start signal is input to the prize judging section 61, the random number setting section 62 sets the driving conditions of the stepping motors 47 of each row and the driving condition of the design drum 54. Set random number data (one of out of reach, out of reach, jackpot) for determining the stop symbol. Based on the random number data, the motors 47 in each row are set according to the set conditions (time and speed) according to the respective pulse outputs sent from the motor control unit 63.
To sequentially rotate the symbol drum 54. After that, when the motors 47 and the design drums 54 in each row are sequentially stopped, based on the stop position of the index 58 with respect to each detector 50, each counter section 64
Is "0 to 15" with 12 pulses as the counter value for one symbol
And input to each symbol detection unit 65.

Accordingly, each symbol detecting section 65 determines each line 35a, 3a on the transparent body 31 side based on each counter value.
The stop symbols of the symbol drum 54 in each row on 5b are detected and determined, and the detection signal is input to the winning determination unit 61.
Finally, the winning determination unit 61 individually or entirely determines the combination of the respective stopped symbols based on the input order of the detection signals. As a result, each line 35a, 35
In the combination of stop symbols on b, "big hit" illustrated in FIG. 8 when the same type matches in all rows, and "type hit" illustrated in FIG. 7 when the same type matches in the left and right columns and different types in the middle row do not match. "Reach out", all other than these "out" as illustrated in FIG.
Are determined respectively. Then, at the time of the start input, at the time of symbol change and at the end, and at the time of a predetermined symbol combination condition, a sound effect from a speaker (see FIG. 9) provided in the main body of the pachinko machine, the lamps 38 and 39, and The effect light from the illuminating means 51 in the row is respectively generated via the output control unit 66.

Further, the basic symbol variation control according to the symbol variable display device D, that is, the symbol display unit 45 of each row.
Motor 47 and design drum 54 in
The rotation control and the like are summarized and set as follows as exemplified in the time chart of FIG. (a) When the power is turned on, the three columns start to fluctuate, and the "missing symbol combination" illustrated in FIG. 6 is stopped and displayed on each of the established lines 35a and 35b. Then, the stop symbols in each row are confirmed as the origin position before the start by the index 58 for the detector 50. (b) As for the start of the symbol change by the start input, the start is performed with a predetermined time difference in the order of the left row, the middle row, and the right row, and in a continuous fluctuation process over a set time, the speed is changed to a predetermined high speed while being stepwise increased. Is done. However, the three rows of high-speed fluctuations include different symbol matching times. (c) With respect to 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 row, a right row, and a middle row in order. (d) Regarding the fluctuation time of each row (from start to stop), at the time of the “out”, the left row, right row, and middle row are “T ₁ , T ₂ , T ₃ ”, respectively.
It is a, the "reach out" time and left columns when "big 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 symbol variable display device D can develop a symbol combination game based on a start input due to a winning ball being detected by the winning prize tool 4 during a game with the pachinko machine, and a "winning symbol" As a result of the display, the special game condition for enabling the electric winning device 11 to be opened can be satisfied. Therefore, the same display device D
An example of a control mode including symbol fluctuation and generation of sound effects and effect lights will be described below mainly with reference to FIGS. 9 and 10.

That is, in the apparatus D, in the initial stage after the power is turned on, the symbol drums 54 in the respective rows are stopped and displayed on the respective winning formation lines 35a, 35b in a combination state of "missing symbols". The origin position of the symbol is confirmed based on the position (count value) of the index 58 with respect to the detector 50. In this state, the winning detection signal of the switch 5 of the starting winning tool 4 is transmitted to the winning determining unit 6 of the electric control device E.
When the data is input to 1, the random number setting unit 62 randomly extracts one piece of data (out of reach, out of reach, or hit) related to the stop symbol in each row of drums and temporarily stores the data in the winning determination unit 61. . Then, based on the random number data, the fluctuation condition (time) of the motor 47 and the symbol drum 54 in each row is set. At the time of the start winning, the sound effect A is generated from the speaker.

On the premise that the motors 47 and the design drums 54 in each row are controlled under the rotational fluctuation conditions set based on the above-mentioned random number data, the left row, 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 row is changed under the change of the symbol matching according to any of “miss, reach, hit”. The right and middle rows are sequentially decelerated and stopped at predetermined time intervals. In this fluctuation process, in the electric control device E, each counter section 64 sets the detector 5 in each row.
The position of the index 58 with respect to 0 is converted and counted to a counter value "0 to 15" based on one symbol of 12 pulses, and a "0" point is set as a "0" point every time both 50 and 58 coincide with each other. The counter value is reset. Note that the effect sound B and the effect light a are generated from the lamp 38 from the start to the end of the fluctuation of each row drum.

Regarding the above-mentioned symbol fluctuation stop, if the random number data is "out of order", the motors 47 and the symbol drums 54 in each row are stopped and fluctuated based on the set time (T ₁ , T ₂ , T ₃ ). On the assumption that each line 35a, 35b
The symbols of different types are stopped and displayed at the top (see FIG. 6).
In response to the stop, each counter unit 64 counts and detects one of the counter values “0 to 15” based on the position of the index 58 with respect to the detector 50 in each row, and outputs the data to the symbol detection unit. Then, the detection unit 65 detects the stop symbol and transmits the information to the winning determination unit 61. And finally, in the winning determination section 61,
The random number data “missing” at the time of starting input and the detection data “missing” from the symbol detection unit 65 are compared and confirmed, and it is determined that the combination of symbols stopped and displayed is “missing”. At the time of "disengagement", the effect light C and the effect light a are generated from the lamp 38 in connection with the stop of each of the row design drums 54.

When the random number data is "out of reach", the motor 47 and the symbol drum 54 in each row are halted based on the set time (T ₁ , T ₂ , T ₄ or T ₅ ). On the lines 35a and 35b, symbols of the same kind in the left and right rows and symbols in the middle row with different kinds of mismatch are stopped and displayed (see FIG. 7). In response to the stop, count detection data from each counter unit 64 and each symbol detection unit 6 are set based on the position of the index 58 with respect to the detector 50 in each row.
5, the symbol detection information is transmitted, and the winning determination unit 61 compares the random number data at the time of starting input with the symbol detection data and determines that the combination of symbols is "out of reach". Note that at the time of this “detachment”, the sound effect C and the effect light a are generated when the left row drum 54 is stopped.
For example, from the N symbols (12 pulses × N), a sound effect D (also referred to as a reach sound) is generated until the right row drum 54 and the middle row drum 54 are stopped, and the effect light from the lamp 38 also flashes. It is changed to light b (also called reach blinking light).

In the case where the random number data is "hit", on the premise that the motors 47 and the design drums 54 in each row are fluctuated and stopped based on the same set time as in the case of "out of reach" described above. On the lines 35a and 35b, symbols of the same kind in the left, right and middle rows are stopped and displayed (FIG. 8).
reference). In response to this stop, each counter section 64 is determined based on the position of the index 58 with respect to the detector 50 in each row.
The symbol detection information is transmitted from each symbol detection unit 65, and the symbol detection information is transmitted from each symbol detection unit 65. In the winning determination unit 61, the random number data at the time of starting input and the symbol detection data are compared and confirmed, and the combination of symbols is "big hit". A decision is made. Even at the time of the "big hit", when the left row drum 54 is stopped, the sound effect C and the effect light a are generated, and thereafter, from the point of N symbols before the stop of the right row drum 54 to the stop of the middle row drum 54. In between, the sound effect D and the changed blinking effect light b are generated. And middle row drum 5
After the stop of No. 4, a sound effect E (also referred to as a big hit sound) and a blinking effect light c (also referred to as a big hit blink light) due to simultaneous synchronization of the lamps 38 and 39 are generated.

In the symbol variation control of the symbol variable display device D, any one of the combinations of symbols illustrated in FIG.
When the "big hit" by the set is displayed, in the pachinko machine, a special game state that is advantageous to the player is established based on this, and the opening operation condition is given to the electric winning device 11 (see FIG. 1). . And as this opening operation condition,
Based on the drive output sent from the electric control device E, the opening / closing member 14 is changed in operation and the winning area 13 is opened with the electromagnetic solenoid 15 being energized and excited for a set time. As a result, many game balls easily enter the prize area 13 and count switches 1 as safe balls.
6 and the V switch 17 are detected and discharged to the back side. By the way, in this device 11, in each opening operation, a restriction condition of the energizing operation time of the solenoid 15 and the number of safe balls is added, and when any of these conditions is reached earlier, the opening operation is terminated. . Further, in this opening state, the continuation condition of the next opening operation is established by detecting one ball of the safe ball by the V switch 17, and up to 16 opening operations are possible under this condition. The operation is terminated.

By the way, in the symbol variable display device D of this embodiment, the effect light is emitted from the lamps 38 and 39 on the transparent body 31 at each time and each condition of the above-described symbol variation control.
Apart from being able to generate (notification light), the illumination control of the illumination means 51 in the symbol display unit 45 for each column,
At each time from the power-on to after each symbol combination display and each condition, suitable illumination for each symbol is performed. For convenience of explanation, the emission color (irradiation color) of the illumination means 51 for each two columns is “blue” from one of the fluorescent lamps 51a, which is always set as a display color, and a change (color change) display color. "Red" from the other fluorescent lamp 51b is taken as an example.

(1) After the power is turned on, the normal color light "blue" is continuously turned on for all the "missing" displays of the symbols in all columns.
Under this condition, at the time of each start input, the light is once turned on and off simultaneously, and then continuously turned on "blue" until the symbol is stopped again.

(2) In the off symbol combination, as shown in FIG. 6, (a) the ordinary color light "blue" is turned on for "off" for all the column symbols, and (b) the "hit" of the left column symbol The color change light "red" is lit once for "use", and under this condition, when the right column design stops, it returns to "blue" lit. It should be noted that "blue" is lit for the symbols in the right and middle rows regardless of the type. Therefore, even if the respective column symbols are different types of "hits", all of them are turned on with the ordinary color light "blue" because they are different.

(3) In the out-of-reach symbol combination, as shown in FIG. 7, the color changing light "red" is once turned on for the symbol in the left column. Next, at the same time as "red" blinking for the right column symbol, the left column symbol is also changed to "red" blinking, and for the middle column symbol, "red" blinks until the stop, "reach blinking" It is said. Then, after the middle row symbols are stopped, all the row symbols are returned to the ordinary color "blue" lighting at the same time. The "red" blinking for the right-row symbol starts in the same manner as in the case of the flashing effect light b of the lamp 38 described above, starting at a point N times before the right-row drum 54 stops, and under this, the left row and the The symbol in the right column and the symbol in the middle column are alternately flashed “red”.

(4) In the jackpot symbol combination, as shown in FIG. 8, in the previous stage, similar to the "reach blinking" in the above item (3), the "row" blinks from the lighting of "red" for the left column symbol, and the right "Red" blinking is performed for the row symbol and the middle row symbol. After the middle row pattern stops, the color change light "red" is applied to all the row patterns at once.
Are flashed synchronously to "big hit flashing". The “big hit blink” may be shifted in a predetermined order for each column, or may be alternately blinking “blue” and “red”.

Therefore, looking at the above-described symbol lighting state, in any of the lightings exemplified in the above-mentioned items (1) to (4), "blue,
The “red” emission color passes through the rim portion 55 of the symbol drum 54 and illuminates the symbol from the inside. At this time, each of the luminescent colors changes (harmoniously) with the base color (yellow) of the symbol drum 54, and irradiates each symbol as a mixed color of "blue and yellow" or "red and yellow". That is, the design is suitably illuminated and displayed. In addition, each pattern is made up of luminescent ink as described above.
In what was painted with (fluorescent ink),
When receiving a mixed variable color, it exhibits exquisite color harmony and is displayed very clearly.

Therefore, at the time of off-reach lighting in item (3) or at the time of jackpot lighting in item (4), which is of most interest to the player, the above-mentioned "blue, red" Illuminating color, the underlying color of the symbol drum 54, and furthermore, the illumination display by comprehensive hybrid color harmony with the symbol emitting ink. This allows the player to enjoy the illuminating beauty of the symbol through his / her sight, and the favorable illumination effect on the symbol enhances the excitement and satisfaction particularly at the time of "big hit". In addition, as an example of the notification control for “out of reach”, as described above, the flashing effect light b by the lamp 38 and the “red” flashing effect light by the lighting means 51 are generated from N points before the right row drum 54 stops. Therefore, the player can know that the reach state corresponding to the actual "reach state" by the combination of the symbols before the appearance of the combination appears, and can enjoy the sense of expectation from an early stage. By the way, it is not too early to see from the original purpose of the notification of the reach state, and there is no confusion to the player.

In the symbol variable display device D of the present embodiment,
As a related matter of the symbol illumination control described above, the light generated from each illumination means 51 is suppressed from being diffused to the outside by attaching the light-shielding seal 60 to the lid 56 of the symbol drum 54 in each row. It is possible to irradiate the design properly exclusively. For this reason, even if the fluorescent lamp is small and emits a small amount of light, it is possible to directly irradiate the design effectively and directly to further enhance the illumination display effect.

Moreover, the design drums 54 in each row are formed in a circular cap shape in which a lid 56 having the light-shielding surface is continuously provided on the inner periphery of a rim portion 55 forming a design surface. When compared with a flat pulley-shaped design drum in which an appropriate number of arms are connected to a conventional rim, the entire structure is strengthened and deformation of the rim 55 due to heat radiation from the motor 47 can be suppressed. In particular, the lid 56 advantageously increases the mass of the entire drum and, above all, makes it uniform radially from the center of rotation. In addition, the inertia force of the entire drum at the time of rotation can be increased, and the distribution can be uniformly distributed in the rotation direction. Thus, the uniform increase of the mass of the design drum 54 and the uniform increase distribution of the inertial force can be achieved, so that the stepping motor 47 used as a suitable rotation driving means in this type of display device can be realized. The rotation failure of the symbol drum with respect to the normal driving can be eliminated, and the rotation can be stably stopped.

Incidentally, in the conventional flat pulley type design drum described above, the following is pointed out as the rotation failure. (a) Due to the small and non-uniform mass of the entire drum, the drum is unlikely to follow the rotation of the motor at the same time, and the rising rotation (initial rotation) tends to be delayed. (b) Due to the small and non-uniform inertial force of the entire drum, the drum is liable to generate pitch-wise discontinuous rotation at the time of motor deceleration driving or low-speed driving. (c) Due to the non-uniform mass and inertial force of the entire drum, the drum is liable to cause rotational vibration with respect to driving of the motor. And, due to the rotation blur, it is difficult to accurately detect the symbol by the detector and the index. On the other hand, according to the symbol cap 54 of the circular cap type in the symbol variable display device D of the present embodiment, these problems can be preferably solved and a combination game with an appropriate symbol variation can be presented.

[Modification] The drum type symbol variable display device to which the present invention is applied is not limited to the above-described embodiment, but may be appropriately modified. For example, the design drum 54 in each row has a large-diameter flange portion having a connection portion with the motor 47 connected to the rim portion, and an appropriate number (including two or more) indexes are arranged at required positions. Alternatively, the pattern may be a background color other than “yellow” and the pattern is painted with normal ink, or may be of course a flat pulley shape. The illuminating means 51 may be other than a fluorescent lamp as three or more having the required coloring light. Design drum 5
The change control and the notification light control of No. 4 may be appropriately changed including the order and the color change illumination. In addition, the present invention can be suitably applied to a slot machine (turning-type gaming machine), including these modified examples, and further, such as a change in the size of the entire apparatus.

[0042]

As described above, in the symbol variable display device for a symbol combination type pachinko gaming machine according to the present invention, a multi-row drum type symbol display unit forming an entity display portion of a symbol combination game is appropriately provided. A drive control circuit in which a stepping motor controlled by pulse driving, a detecting device for detecting a symbol position, and an illuminating means for symbol illumination are arranged at required positions on one driving base which can be connected to the electronic control device. On the other hand, a symbol drum on which various symbols are arranged can be connected to a stepping motor to form a set unit,
A plurality of the symbol display units are arranged side by side, and can be easily and inexpensively manufactured as a symbol variable display device for a pachinko machine and a slot machine, and can be easily handled to easily and accurately perform a predetermined electronic control device. Can connect.

In such a symbol variable display device of the present invention, the symbol drum rotated by the stepping motor in the symbol display unit of each row has an outer peripheral ring-shaped rim portion which forms a symbol surface by synthetic resin molding. A flat pulley-shaped design drum with a suitable number of arms connected to a conventional rim because it is a circular rotating body with a disk-shaped lid having a central boss part connected to the inner periphery of In contrast to this, the entire structure is strengthened and deformation of the rim portion due to heat radiation from the stepping motor can be suppressed. In particular, by this lid portion, the mass of the entire drum is suitably increased, and above all, by making it uniform in the radial direction from the center of rotation, the inertia force of the entire drum at the time of rotation can be increased, and at the same time, the Distribution. In this way, the uniform increase of the mass of the symbol drum and the uniform increase of the inertia force can be achieved, so that the rotation of the symbol drum with respect to the normal driving of the stepping motor used as a suitable rotation driving means is poor. , And stable rotation stop can be achieved.

More specifically, the specific state of the stable rotation of the design drum with respect to the stepping motor is as follows: (a) The drum can smoothly follow the rotation of the motor at the same time with the start of driving, and its rising rotation (initial rotation) Is stable and does not delay. (b) The drum can be stably decelerated / rotated / stopped when the motor is decelerated or stopped at a low speed, and no pitch-like discontinuous rotation occurs. (c) The drum rotates smoothly and stably with respect to the driving of the motor, so that no rotational blur occurs. This makes it possible to maintain accurate symbol detection stop by the detector and the index. It is possible to present a combination game with an appropriate symbol change based on the light rotation and stop of the symbol drum in each row.

Further, in the symbol variable display device of the present invention,
The symbol drum of the symbol display unit in each row is formed into a substantially circular cap shape in which a lid is integrally connected to one side in the rim portion, so that the symbol drum is arranged with respect to the stepping motor attached to the drive base. Can be connected in a state where the symbols are covered, so that the symbol display units in each row can be configured as a compact unit having a required minimum width. Moreover, in the case of the design drum, it is formed of a transparent synthetic resin material as appropriate.
Since the light-shielding surface for the light source of the illuminating means is formed on the side surface of the lid, the light from the light source is prevented from diffusing to the outside of the drum, so that the pattern on the outer periphery of the rim can be properly applied. As a result, even if the light source is small and emits a small amount of light,
By effectively illuminating the symbols directly, the illumination display effect according to the symbol combination game can be further enhanced.
