[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a direct-acting hitting ball launching device for a pachinko game machine,
In a pachinko game machine capable of developing a predetermined game using a pachinko ball, a hit ball in which a pachinko ball (game ball) sent one by one to a launch position in the machine is directly moved by a linear reciprocating solenoid. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hit ball launching device that is launched by a rod and fires into a game board.

[0002]

2. Description of the Related Art A hitting ball launching device implemented in a pachinko game machine is divided into two types in terms of the configuration of a hitting portion which is operated based on the operation of an operation handle. (B) Rotary solenoid drive type: Excitation rotation of the drive rotary solenoid of the hitting ball actuation unit, in which the hitting rod supported at another position is reciprocated to hit the game ball in response to the rotation of the drive motor of the unit. The most commonly used is a type in which a ball hitting rod connected to a rotation shaft in the solenoid is reciprocated to hit a game ball. And in any device, game operation (ball hitting operation) with the operation handle part on the front side of the front frame
In, the hitting rod of the hitting action section on the back side of the front frame hits the game ball sent one by one to the firing position of the firing rail installed at a predetermined firing angle and fires on the firing rail, The ball is hit into the board while flying along the guide rails of the game board. The most important requirement is to accurately and rigorously launch one game ball at a time.

[0003]

The hitting ball launching device described above directly affects the contents of the pachinko game, and therefore requires strict and delicate adjustment, and the overall size of the device can be reduced. It is being sought. Therefore, in addition to the above-described types (a) and (b), a large number of linear reciprocating solenoid-driven types have been proposed as small-sized hitting and launching devices excellent in reliability and durability. In recent years, it has been newly reviewed and actually being tried. In an apparatus of such a form, specifically, JP-A-56-8081, JP-A-58-165876, JP-A-6-134089, and JP-A-6-1340
No. 90, JP-A-8-141150, JP-A-8-141
As disclosed in JP-A-141151, JP-A-4-114381, JP-A-6-52884, etc., the basic configuration is that a certain range is linearly reciprocated in a pulse-controlled electromagnetic solenoid. A movable plunger type hitting rod is inserted and supported, and a hitting portion (generally a coil spring) for a game ball is attached to the tip of the hitting rod.
In the game operation (hitting operation), the hitting rod is instantaneously advanced at the time of the excitation operation of the solenoid, and hits the game ball at the hitting portion. To continue the straight line launching.

However, in any of the hit ball launching devices disclosed in the above-mentioned publications, there is a problem that stable and suitable ball flight is not maintained or guaranteed. Regarding the cause, the applicant of the present invention has tried to implement the above-mentioned Japanese Patent Application Laid-Open No.
No. 0 and Japanese Unexamined Patent Application Publication No. 8-141151, the products of the “ball launching device for pachinko” were examined while stacking test tests over a long period of time. And the change in the exciting force of the electromagnetic solenoid are pointed out as major factors.
For this reason, as a problem caused by the former, there is a case where the hitting rod rotates (vibrates) in an angular range corresponding to each linear movement every time,
It has been found that the hitting ball cannot always hit a certain position accurately against a game ball seated at the firing position. Also, as a problem caused by the latter, looking at the state of the electromagnetic solenoid immediately after the start of the ball hitting operation and after a lapse of the required time, the exciting force has decreased as the temperature of the solenoid itself has risen, and the ball jumping state It is pointed out that it may not be possible to maintain a constant. Therefore, when these two act synergistically, the ball jump becomes unstable and it is impossible to accurately hit a predetermined position in the board, or the ball is launched until a certain time elapses from the start of the game. Due to the frequent occurrence of defects, it was not possible to continue a comfortable pachinko game.

On the other hand, the drive control unit F ₄ performs general input / output control of each of the electric components related to the above-mentioned ball feeding and launching. As shown in FIGS.
A circuit board 43 constituting necessary circuits is built in an openable case 40 which is detachably mounted on the back side of the installation board 3 of FIG. , by using 45, 46, 47, 48, power in order from the right side in FIG. 5 (AC24V), firing solenoid 22, the ball feed solenoid 9, the operation handle portion F variable resistor 14 in _1, the switch 15 And the touch sensing ring 16 are connected via respective wirings or the like. However, as shown in FIG. 5, the wiring h connected to the relay connector 18 extends from the hole 3a opened in the installation panel 3 to the back side, and three wires for the variable resistor 14, the switch 15 and Touch sensing ring 1
It is divided into three for six, and is connected to the connectors 47 and 48 concerned. The case 40 is
As schematically shown in FIG. 11, the receiver 40a and the cover 40b
Are fixed to the back of the installation board 3 with screws, and are set with a holding claw 41a formed on the holding base 41 and shaft portions 41b on both lower sides.
The engaging shaft 42a formed on the back side of the receiving board 40a is engaged with the shaft supporting portions 42b on both lower sides to be detachably held. The circuit board 43 is provided with adjusting tools 49 and 50 for adjusting the touch sensitivity and the ball exciting power. Incidentally, a touch circuit (not shown) of the substrate 43 and the touch sensing ring 16 are collectively referred to as a touch switch for convenience.

[0018] Then the drive control unit F _4, as an electrical maintenance measures for firing the solenoid 22 so as to stabilize the excitation force characteristic performs residual heat insulation when not driven. That is, as schematically shown in a block diagram in FIG.
A residual heat power supply circuit 52 for the drive power supply circuit 51 of the firing solenoid 22 is formed on the circuit board 43. When the power is turned on, before the hitting operation in which the switch 15 and the touch sensing ring 16 are not detected (OFF), the driving power supply circuit 52 is kept in a stopped state, whereas the remaining heat power supply circuit 52 is in a driving state. , And is set so as to apply a constant voltage to the firing solenoid 22 to keep the residual heat. The firing solenoid 22
Becomes closer to the resistance value of the solenoid itself at the time of actual operation, and the difference between the excitation force characteristics (strong and weak) at the time of stopping and at the time of driving is reduced. When the switch 15 and the touch sensing ring 16 are detected (ON) with the start of the hitting operation, the residual heat power supply circuit 5
2 is turned off, the drive power supply circuit 51 is turned on, and a voltage corresponding to the volume adjustment amount of the variable resistor 14 is applied to the firing solenoid 22 to excite the preheating heat retention condition. A launch based on force is performed. Reference numeral 9 in FIG. 12 schematically shows the ball feeding solenoid.

The excitation force characteristics relating to the presence / absence of such a pre-heating and heat-retention countermeasure can be compared with a basic example shown schematically in FIG. Conditions That hitting operation since the start of the firing solenoid 22 driven excited by successive hitting operation, in the case where no waste heat insulation, as illustrated by a two-dot chain line in the figure, which is kept at room temperatures T ₁ When in the drive start, will be energized force as the temperature rise relating to the later time (hitting force) is reduced, the height difference between the excitation force during the period from the start time until the elapsed time of the time t ₂ is Due to the large size, a large change occurs in the ball flying state, and as a result, there is a considerable difference (variation) in the driving position into the game board G.
Occurs. On the other hand, if you keep the residual heat,
Preheating temperature T ₂ will be initiated driven from the time that is pre Ji because kept, even as an excitation force decreases with increasing temperature as illustrated in the following in view solid, driving time (t ₂ -
The height difference of the exciting force within t ₁ ) is small. Consequently, to eliminate the instability launch of within the time t ₂ immediately following hitting operation start (sphere skipping bad), good stability towards certain site within the game board G while maintaining less variation launch Can be driven.

The characteristics schematically shown in FIG. 13 are examples of data examined under the condition that the operation lever 13 is held at a fixed operation position and the volume adjustment of the variable resistor 14 is fixed. And in the same figure, the room temperature T ₁
About, in the summer, the average temperature (for example, 25-27 ℃) assuming the temperature in the game hall in the winter,
The preheating temperature T ₂ is set to, for example, about 45 ° C. that can secure a sufficient exciting force. Then, to the time t ₁ required for the thermal insulation of the remaining heat temperature T ₂ is minutes 15-20, a time t ₂ 4
The example is 5 to 60 minutes. Therefore, although it takes t ₁ hour from the time the power is turned on as the residual heat insulation conditions of firing solenoid 22, which is what not deal with only a little speed up the power-up time before the opening of the hole obtained, also of somewhat in the meantime Even if an electric current is required, a great advantage is found in stabilizing a hit ball and improving ball flight.

[0021]

In the pachinko game machine of the present embodiment constructed as described above, common game components C, D, and E shown in FIG. 1 and FIG. , F, and a predetermined game board G are equipped and configured respectively. And a setting frame (not shown) in the game hall
The entire front frame B described above is assembled and set on the outer frame A installed with a predetermined inclination and upright posture, and the power is turned on and held (power is held), so that the game can be provided as a vertical ball game machine.
Upon start of the game in this one, by performing the hitting operation by the operating handle F ₁ hitting launcher F, based on the game ball H in the upper sphere dish D to the ball feeding operation of the ball feeding device 8 1
Sphere by sitting held in the firing position P crowded feed to the firing unit F ₃ side, hitting operation portion F ₂ of the firing solenoid 22 This is followed
The game ball H is struck by the striking rod 23 that reciprocates linearly in response to the current-carrying drive excitation, and is fired on the firing rail 38 and struck into the game board G to develop a required pachinko game.

In the hit ball launching apparatus F of the present embodiment implemented in such a gaming machine, the main units F ₁ , F ₂ , F ₃ , and F _{4, which} are unitized and divided, are installed in individual installation portions. Will be equipped. That Specific implementation (installation) mode, the first operating handle section F _1, to the holding cylinder 10a of the mounting portion 10 in the lower sphere dish E, by connecting fixed fitted to the cylindrical portion of the gripper 11, It is set in a predetermined direction (see FIGS. 2, 3, and 4). In addition, the hitting operation section F ₂
And in the launching section F ₃ , it can be handled by being constituted in a united form of one support board 20 unit, and this support board 20 is positioned and set on the front face of the game assisting board 6 in the holding frame 4 inside the front frame B and from the front side. By fixing the screws, the hitting rod 23 of the firing solenoid 22 and the firing rail 38 can be detachably installed while maintaining the setting angles α and β of each other (see FIGS. 3 and 10). Then the drive control unit F _4, handle obtained in a state of assembled the case 40 and the holder 41, by aligning the holder 41 to the installation board 3 back side of the predetermined portion of the front frame B by screw-fixed from the rear side The entire case 40 containing the circuit board 43 is detachably held (see FIGS. 4 and 5). Then, as illustrated in FIG. 5, the connecting members 44, 45, 4 of the circuit board 43 are mutually connected between the main parts F ₁ , F ₂ , F ₄ .
The power supply (AC 24 V), the switch 15 and the touch sensing ring 16, the variable low-resistance device 14, the firing solenoid 22, and the ball-feeding solenoid 9 are connected to 6, 47 and 48, respectively. (Energized state).

In the hit ball launching device F equipped as described above, based on the pulse control of the drive control unit F ₄ receiving the input condition by the hitting operation with the operation handle unit F ₁ ,
The hit ball operation is performed in synchronization with the ball feeding operation. That is, the pulse output is performed based on the detection condition of the touch sensing ring 16, the detection condition of the switch 15, and the volume adjustment condition of the variable resistance device 14 according to the operation amount of the operation lever 13 input to each part of the circuit board 43. The ball feeding solenoid 9 and the firing solenoid 22 cause the ball feeding solenoid 9 and the firing solenoid 22 to move one by one by the first and second pulses output from the unit at the same timing.
Drive excitation is performed in units of spheres in accordance with the set timing.
As a result, the game ball H for each ball is sent to the firing site P of the firing rail 38 and sits down, and the ball H is launched by the linear operation of the hitting rod 23 and is hit into the game board G. However, the pulse output control in the drive control unit F _4, the combined pulse for pulses and hitting for the spherical feeding is set as a basic cycle of each ball unit, each ball based on the pulse setting The ball feeding and hitting action of the ball are stabilized stably.
In holding the operation of the operation lever 13, the switch 15
Is switched to the ON / OFF condition via the operation piece 19, so that the game ball can be hit in a single shot.

In the hitting ball launching apparatus F of this embodiment, a suitable launching suitable for the above-described configuration and setting conditions can be performed. That is, in hitting operation in the hitting operation unit F _2, hitting rod 23 that is linear for each driving excitation firing solenoid 22 is guided regulated by the positioning groove 31 and the guide ribs 32 for preventing rotation shake While moving forward a predetermined stroke S instantaneously, and moving the hit ball 30 to the firing position P
Was directly those striking aligned with the set position of the game ball H periphery seated, an effective excitation force can launch drives out hitting fraction S ₂ in the stroke S which acts. Therefore, if the hitting piece 30 is the most suitable coil spring,
By keeping the front end (direct hitting end) always in a fixed direction and moving forward to a position matching the mark 54, the game ball H can be shot accurately without displacement (see FIG. 9). Under this condition, the hitting rod 23, which has been prevented from rotating and swinging, linearly moves forward along the launch angle α that is set smaller than the firing angle β of the firing rail 38, and moves the game ball H with the hitting piece 30. By hitting, it is possible to give the game ball H a launching force having a reverse rotation tendency due to the angle β-α. This allows the game ball H
