Description

[Detailed description of the invention] This invention provides upper and lower chuckers approximately on the vertical center line of the front surface of the mounting board, and the lower chuckker covers its upper part with a pair of movable guide pieces that are permanently located in contact with both sides of the upper chuckker. It is configured to make it difficult to capture a hit ball, and to make it easier for the lower chutker to capture a hit ball by the ball guiding action of the movable guiding piece by the reversible movement of the movable guide piece that occurs appropriately, and then to return it to the permanent position. No Chinko machine's on-machine safe ball generator, the safe ball generator that hardly changes the ball catching action of the upper chucker and makes it difficult to catch balls only for the lower chuckker, is attached to the upper part of the movable guiding piece. The object of the present invention is to provide a structure that is caused by a graceful and clear reversible movement between both sides of the chucka and both sides of the lower chucka.

An embodiment of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 denotes a mounting board formed over a wide area, with ball inlet holes 2 and 3 provided at the upper and lower parts of the vertical center line on the front surface, and a pair of left and right holes 2 and 3 arranged at the center 4 between the artist inlet holes 2 and 3. Arc groove 5

Long hole 17 in the horizontal direction
17 are formed in association with the first sliding holes 7,7.

Reference numeral 21 designates a medical cover plate which exposes the support pins 6.degree. 6 and the second sliding holes 8, 8 on the front surface of each lever 14, 14, and covers up to the inner edge of the arcuate groove 5.degree.S.

At the end of each lever 14, a substantially convex arc-shaped outer guide surface 20 is joined to both sides of the upper chuck 10 as shown in FIG. A movable guide piece 18 is fixed that brings the guide surface 19 close to both sides of the ball entrance of the lower checker 11.

As shown in FIG.
At the position shown in the figure, the tilted movable blade 12 is brought into contact with the inner guide surface 19.

A vertical sliding groove 22 corresponding to both sides of the vertical plate 9 is provided on the back surface of the mounting board 1, and a horizontal eccentric pin sliding groove 24 protrudes to the front side as shown in FIG. After fitting the sliding plate 23 provided with a pair of operating pins 25.25 and passing the operating pins 25.25 through the first sliding holes 7, 7, the lever 1
4 and 14, and an eccentric pin 28 provided on a disc 27 fixed to the output shaft of a small motor 26 attached to the rearmost surface is inserted into the eccentric pin sliding groove 24.

Further, the disc 27 is provided with recessed notches 29 at one place on its circumferential surface or at two places with an interval of 1800 degrees, and the spring contact operating lever 31 of the microswitch 30 inserted into the holding circuit of the small motor 26 is inserted into the holding circuit of the small motor 26. It comes into elastic contact with the circumferential surface as shown in Figure 3.

Immediately above the lower ball inlet hole 3, a pair of left and right support pieces 32 are protruded from the mounting board 1, and a U-shaped plate 33 shown in FIG.
supports the shaft 34 of.

The U-shaped plate 33 has a pair of pins 35 which are passed through the second sliding holes 8.8 and engaged with the husbands of the movable vanes 12, 12.
A rocking plate 38 is provided on the rear side of the U-shaped plate 33, and a protruding piece 36 protruding to the rear side is provided, and one side is pivotally supported on the back surface of the mounting board 1 by a shaft 37 as shown in FIG. , insert the protrusion 36 into the elongated hole 39.

A spring 40 is applied to the rocking plate 38 to maintain the posture shown in FIG.
The rise shown in FIG. 1 occurs through this.

Reference numeral 41 is attached to the back surface of the mounting plate 1, and a plunger 42 that descends with the excitation operation presses the free end of the swinging plate 38, thereby raising the front end of the U-shaped plate 33 and moving the movable vane plate 1.
2. Tilt the 12 as shown in Figure 2.

To explain the operation of the above embodiment, the small motor 26 is driven with a starting circuit closed by a switch (not shown) activated by a safety ball entering the upper chucker 10 or any other chucker and flowing to the rear side. After the contact operating lever 31 escapes from the concave notch 29 of the disc 27 and comes into contact with the circular circumferential surface as shown in FIG. When the contact operating lever 31 falls into the recessed notch 29, the circuit is opened and stopped.

The solenoid 41 is simultaneously driven to lower the plunger 42 while the small motor 26 is being driven, or the other switch described above is closed by a safety ball to create a circuit configuration in which it is driven open.

The action described below is based on the small motor 26 and the solenoid 41.
The explanation will be based on a mode in which the small motors 26 and 26 are driven independently of each other, and the small motor 26 stops every rotation.

When the small motor 26 is stopped, the contact operating lever 31 of the micro spinch 30 falls into the recessed part 29 of the disc 27, and the movable guide pieces 18, 18 are placed on both sides of the upper chuck 10 as shown in FIG. Contact and be present as required.

Therefore, the upper part of the lower chuck 11 is connected to the movable guiding piece 1.
8 and 1B, and the balls flowing down from above enter the upper chucker 10 or the outer guide surface 2 of the movable guiding piece 18.
Even a ball that flies from the side at the lower part of the movable guide piece 18 is rejected laterally by the movable wing plate 12, 12 as shown in FIG. If it is, it will hardly be captured.

However, in this state, when the solenoid 41 is activated, the swing plate 38 is pushed and swung by the plunger 42 only during the activation, and the movable vane plate 12 is moved via the U-shaped plate 33 as shown in FIG. By tilting the target, there are more opportunities for capture.

When the small motor 26 rotates once as described above due to the generated specific safe ball, the sliding plate 23 engaging the eccentric bead 28 of the disc 21 rises and the actuating pin 25 moves the lever 14 and the movable inducer piece. 18 is moved to the position shown in FIG. 2, it moves upward with the downward movement of the sliding plate 23 and returns to the permanent position shown in FIG. 1. However, while the movable guiding piece 18 moves as described above, When the upper part of the chutzer 11 is uncovered, the ball flowing down the side of the upper chutker 10 from above has more chances to hit the inner guide surface 19 and enter between the movable vanes 12 of the lower chutker 11, and the solenoid 41 When the movable vane plate 12 is tilted as shown in FIG. 2 due to the overlap of the drives, the chances of the lower chucker 11 catching a hit ball increase more and more.

As described above, the present invention has an upper chuck 10 and a lower chuck 11 located approximately on the vertical center line of the front surface of the mounting plate, and is normally located at a permanent position touching both sides of the upper chuck 10, covering the upper part of the lower chuck ker, and A pair of movable guide pieces 18, 18 that move from a permanent position to both sides of the lower chatker 11 and then return to the permanent position again.
At the same time as the movable guiding pieces are separated from both sides of the upper chucker 10, the upper part of the lower chucker 11 is uncovered and the balls flowing down from both sides of the upper chuckker are guided by the inner guide surface 19. The lower chutker 11 can increase the chance of catching a ball that flies in from the side under the movable guiding piece 18 by creating an opportunity for the lower chutker 11 to catch the ball and guide it to the lower chutker 11. Moreover, since the momentum of the movable guide piece 18 is large and elegant, it has the effect of making it difficult to catch the ball and making the front surface of the pachinko machine dynamically decorative.
