And can be guided while being held in an appropriate extended state as shown in FIG. The design belt B can be quickly and easily mounted using the displacement of the adjustment tool 68 to the non-guide position.

[0023] Then the in detector 72, and detects one of the symbols marks m ₂ for each position of the reference mark m ₁ and the detection reference symbols belt B will be described later, by considering the pay line position setting Two optical sensors 72a are installed at predetermined detection intervals at the detected detection positions (the lower part in FIG. 5) and are connected to the detection circuit of the set plate 61. And as the detection example, both sensors 72a of the light transmission type, 72a are perforated detected by the light reflective state for each of the marks m _1, m ₂ (code signal "1"), the light transmission state of each symbol d _1, d ₂ Is set so that no detection (code signal “0”) is performed and the optical signal is converted into an electric signal. In the lighting fixture 73, the lamp 75 of the lamp base 74 fixedly connected to the lighting circuit part of the set plate 61 is housed facing forward in the lamp cover 76 hung on the center front side of the set plate 61. When the lamp 75 is turned on and blinks, a pattern for a plurality of frames can be illuminated from the inside.

On the other hand, the symbol belt B is, as a basic example, a symbol of a predetermined size produced by a processing method including printing, vapor deposition, lamination, and cutting on two ultra-thin transparent film-like base materials having high tensile strength and small expansion and contraction change. Both ends of the display band b are welded to form one endless belt. As for the symbol display band b, as one of specific examples, as shown in FIG.
Large and small symbols (for convenience, alphabetic characters are not shown) d ₁ and d ₂ , depending on the type, the number of display frames (for convenience, 21 symbols with counter values “0” to “20” as symbol numbers) Printing is performed with ink of each color in a predetermined order by setting an arrangement interval (symbol center interval). Under this symbol condition, the detecting means 7 is used as a position detecting medium at one reference position and a predetermined position for each frame of all symbols.
The reference mark m ₁ detected by 2, the symbol mark m ₂ are formed arranged drives out vapor deposition material.

All of the above-mentioned symbols d ₁ and d ₂ are formed of ink of each color having a high sensor sensitivity (light transmittance) of the detecting means 72, and each of the symbols for a large hit and a small detachment. Are arranged at the center interval according to the set pulse number unit. Further, all the marks m ₁ and m ₂ are formed of a vapor-deposited material such as aluminum or chromium which exhibits a suitable light reflecting surface (light shielding surface such as silver) with the lowest sensor sensitivity, and the reference mark m ₁ At the center position of one reference symbol (for example, “A”), a large detection size suitable for the detection performance or the like of the detecting means 72 is set, and all the symbol marks m ₂ are shifted by a predetermined pulse displacement amount at the central position of each symbol. It is arranged with a small detection size per minute. Numerals are indicated on the symbol display zone b "0 to 20" refers to convenience predetermined counter value for the symbol number indicating the location and type of all the symbols in the program processing control, the detected position of the reference mark m ₁ Is counted as the reference value “0” to the final value “20”, and is reset to “0” again.

Symbol display band b with such a vapor deposition mark
In the design belt B, the respective marks m ₁ and m ₂ can be formed and arranged at required positions without being restricted by all the designs d ₁ and d ₂ ,
In particular, even if the pattern is superposed on a part of the design, it is detected properly while maintaining the light transmission condition (light reflection state). The required symbol (for example, a hit symbol) can be formed large in the width direction without being restricted by the mark position, and can be suitably used as a high-grade information mark-type symbol display material. Also, all the symbols d ₁ , d ₂ , marks m ₁ ,
Since m ₂ can be visually recognized clearly from the outer surface of the base material, degree or module (position, distance, etc.) of the respective printing or vapor deposition on the quality or the like of accurately inspected through visual handlers special detection determination equipment as no unnecessary You can check. Moreover, since the design and the mark are located at the joint surface of the two base materials and are covered and protected, the design display band b and the design belt B
During the handling and use of, these peeling and missing are avoided.

As an example of a basic pattern fluctuation detection stop mode using the above-mentioned information-marking type pattern belt B, all the marks are detected during the continuous movement of the belt and the control circuit device E side. in in the assumption to be read process, read from the time the detection means 72 has reference detecting the reference mark m ₁ each time it detects a symbol mark m ₂ for each position, drawing number counter value corresponding set one After a predetermined time (set pulse time) from the end of the detection, the drive motor 63 and the symbol belt B in the row are stopped, and the symbol corresponding to the symbol number counter value is stopped on the winning line. Therefore, according to such an example of the symbol stop display by the direct detection of the mark, even if a shift (slipping) or the like occurs during the movement of the belt, the error of the displacement amount for each symbol of the symbol has no effect. , Yu detection time point of a predetermined symbol mark m _2, it is possible to accurately stop displaying the symbols corresponding thereto.

[0028]

In the pachinko machine according to the present embodiment in which the game board P constructed as described above is set, in the same manner as in the conventional pachinko machine, the ball feeding operation and the hit ball launching operation based on the game operation are performed. Pachinko ball (game ball) is 1 by cooperation with
Each ball is sent to the launch position and launched into the game area 2,
A pachinko game can be played in which the ball is divided into a safe ball entering the winning opening 3, 7, 9, 10 in FIG. Then, for each safe ball, a set number of prize balls are paid out based on the detection processing conditions for each ball, and are discharged to the player side (ball tray side). In such a pachinko game, a special game including a symbol change stop of the symbol variable display device D and an opening operation of the winning device 6 is performed on condition that each time a game ball is detected in the starting winning opening 3 as winning. Will be established at the same time.

The pachinko machine according to the present embodiment can display symbols on the game parts M on the game board P in consideration of the above-mentioned start winning conditions relating to the special game, and at the same time, favors the game balls with respect to the starting winning opening 3. The following is a detailed explanation mainly on the starting winning mode.

That is, during the pachinko game on the game board P, the game balls naturally falling along the game nails or the like in the game area 2 are the left and right elevating guides 41, 41 in the game ball guide of the game component M. May fall directly on the outer end portion (on the fulcrum portion), or may fall through the receiving ports 36, 36 on each side and fall on the central portion of the guide. Under this condition, in the gaming component M, the drive motors 48 of both the lift drive mechanisms 47
In the example of the state in which it is driven in accordance with a preset energizing drive condition (for example, the time of energization of the pachinko machine),
As the respective cams 50 rotate, the left and right elevating guides 41 are continuously moved up and down and tilted including the first and second guiding state positions, and the game balls are started according to the respective state positions.
Will be divided into guidance.

Therefore, as a guide mode of the game ball, first, when observing the case where both the lift guides 41 receive the game ball at the first guide state position (downward end position) shown in FIG. You will be presented with indirect guidance. That is, the game ball received on the guide body 41 is the main body 2 of the game component M.
1 While being in contact with the front surface, it is guided to the center side along the steeply inclined ball receiving surface 46, and after falling from the downstream inner end of the guide body 41, once falls on the guide wheel 5 to rotate freely. Depending on conditions and the like, it falls and is guided separately to either the outward side or the inward side. In many cases, the game balls guided to the inside are guided to the starting opening 3 side along a peripheral game nail (not shown) or the like, and are finally classified into winning or non-winning at the starting opening 3. Will be. Therefore, in such an indirect guidance state, the conditions for entering the starting port 3 are relatively difficult and small.

On the other hand, when watching the case where both the lift guides 41 receive game balls at the second guide state position (upward end position) shown in FIG. 8, it provides direct guidance to the starting port 3. become. That is, in most cases, the game ball received on the guide body 41 is directed to the inclined path portion 37a side of the guide path 37 of the game component M along the depth gradient of the horizontal ball receiving surface 46. It is quickly transferred (see FIG. 10). Then, after this, the game balls are guided from the inclined path portion 37a to the central collective concave portion 37b, and then are guided from the fall guide port 39 toward the starting port 3 directly below the front face, and finally, are guided. Nearly all the spheres will win. Therefore, in such a direct guidance state, the conditions for entering the starting port 3 are extremely easy and many are maintained.

In the above-described game ball guiding state of the game component M, the game ball M is received at the time of the first guiding state position under the condition that both the elevating guides 41 are continuously moving up and down. The game ball may be sent to the guide path 37 side to be guided directly, and the game ball received at the time of the second guide state position may be sent to the main body 21 without being sent to the guide path 37. May fall down to the front side of the vehicle and be guided indirectly. In any of the guide states, the game ball jumping to the window 22 side has a main body 21 due to the inclination of the lower plate of the window 22.
Fall to the front side of In addition, the game balls sent to the guide path 37 side at the second guide state position of the elevating guide body 41 are suitably controlled by the control step 38 so that the game balls are prevented from stopping inside the main body 21. (See FIGS. 6 and 10).

As described above, in the pachinko machine of the present embodiment, in the game board P capable of presenting a special game, indirect guidance and direct guidance of the game ball toward the starting winning opening 3 can be more suitably achieved by the game component M. By changing the entry condition of the game ball alternately between a relatively difficult and small state and an easy and large state, the occurrence rate of the start prize condition for the special game is changed with an appropriate time difference. Thus, the average occurrence rate per unit time, which is preferable from the viewpoint of the entire game, can be maintained.
That is, the game component M itself can be implemented as a suitable game tool for maintaining appropriate start winning conditions. The starting prize conditions described above are based on the starting port 3
The entered safe ball is detected by the switch 4 and becomes effective when it is input to the control circuit device E of the symbol device D, and the effective portion is displayed on the holding lamp 35 of the game component M.

In the pachinko machine according to the present embodiment, a special game can be made available based on the start winning condition appropriately generated as described above. That is, the control circuit device E
Design fluctuation command (data) sent from each start winning condition from
The symbol display unit U of the symbol device D is operated in the set column order, and the symbol d is driven by the pulse control drive of the drive motor 63 and the continuous movement of the symbol belt B.
₁ and d ₂ are variably displayed. After that, based on the example of the direct detection stop of the reference mark m ₁ and the symbol mark m ₂ , the motor 63 and the belt B are sequentially stopped, so that the respective symbols d
₁ and d ₂ are fixedly displayed on the pay line 26 in the see-through window frame 25 of each row in the gaming component M. If the display result of the symbols is a set combination condition, a "big hit" is established, and in response to the "big hit" being established, the winning device 6 is opened based on the set opening pattern, and a special game is performed. Be expanded.

Therefore, in the pachinko machine of this embodiment,
As described above, during the pachinko game, the starting prize winning conditions can be optimized and a suitable incidence can be maintained.
The number of symbol fluctuations per predetermined time can be optimized and the time difference interval can be validated. Based on this, the symbol combination (big hit) can be reasonably established based on the set probability, and the opening operation of the winning device 6 can be achieved.
