At this time, the control piece 22 is retracted from the guideway 14 and is in an open state, allowing the subsequent ball to flow in.

On the other hand, the prize ball discharge path 17 is equipped with a bell 24 at its lower end, and has its opening facing a communication window 25 provided in the base plate 11 and continues to an overflow ball passage 26. A ball extraction gutter 18 arranged in parallel with the frame body is formed as an independent passageway so as to reach the lower end of the frame body.

27 is a safe ball passage provided on the back side of the board 11 in the lower half of the mechanism frame 9, that is, inside the chamber 12; 28 is a controller that allows consecutively flying safe balls to pass one by one; 29 is a safe ball detector that detects safe balls flowing down the safe ball passage 27, and 30 is an interlocking rod that transmits the operation of the safe ball detector to the operating member 23 of the prize ball device.

The safe ball passage 27 opens and communicates with a sloped ball shifting frame 31 formed by the lower upper edge of the case 7 and the lower upper edge of the mechanism frame, and communicates with the controller 28.
is installed facing the upper folded part of this safe ball passage.

The controller 28 is equipped with a weight at the rear end (right side in FIG. 2), and always urges the front end upward with the pivot 32 as a fulcrum, waits for the safe ball to flow in, and the safe ball is placed in the concave receiving portion 33. When the ball enters the ball, it receives the weight of the ball and converts into a forward-leaning position and sends it out into the path formed in a loose arc shape. This prevents it from flowing into the aisle.

The safe sphere detector 29 has a shaft 3 implanted in the substrate 11.
5 has a shaft bearing near its rear end so that its tip faces the safe ball passage formed in the arc shape,
When a safe ball flows through the controller 28, the ball is received at the tip and swings about the shaft 35 as a fulcrum to detect the safe ball, and the swinging rear end is connected to the interlocking rod 30. .

The interlocking rod 30 is made of a heavy metal rod, and its upper end is connected to the operating member 23 of the prize ball device.
When the safe ball is not passing, the weight of this interlocking rod flips up the tip of the detector 29 to prepare for the safe ball to pass, and the actuating member 23 is pivoted around its support shaft 36. A pin (not shown) implanted in the case lid 21 of the prize ball case is hooked to the notch 37 formed at the lower edge of the ball case by pulling it down, so that the case lid 21 is restrained in a closed state. be.

In the figure, 38 is a detection plate for detecting when a predetermined number of prize balls cannot be supplied to the prize ball case 15 due to a shortage of prize balls in the prize ball guiding path 14, and 39 is a detection plate for detecting a shortage of prize balls. A swinging rod that restricts the operation of the interlocking rod 30 when detected, 40 is a swinging rod and an actuating member 2.
It is a link that connects 3.

The detection plate 38 is formed in an L shape, and is connected to the substrate 11.
The detection piece 38a is always placed facing the guideway 14, and if there is a prize ball on it, it is pushed up with the diameter of the ball. , if it is missing, the taxiway 1 will be closed under its own weight.
4, and the stopper piece 38b is made to slip under a pin 42 provided at one end of the swinging rod 39 to prevent its descent.

The swinging rod 39 is a support shaft 4 installed on the room 12 side.
The taxiway 14
is filled with prize balls, thereby pushing up the detection plate 38 and operating normally, the actuating member 23 swings about its support shaft 36 due to the vertical movement of the interlocking rod 30. When the detection piece 38a of the detection plate falls down, that is, when the supply of prize balls is insufficient, the stopper piece 38b
is placed under the pin 42 to prevent its swinging movement, thereby restraining the operation of the actuating member 23 and stopping the ejection of the prize ball. Therefore, due to the function of this device, when insufficient prize balls are stored in the prize ball case, the prize balls will not be released as the missing prize balls.

The mechanism frame 9 that incorporates the above-mentioned award ball device, safe ball detection device, interlocking device, etc. has shafts 44, 45 provided above and below one side edge, and bearing fittings 46, 47 provided above and below the right side edge of the base frame plate 1. It is hinged so that it can be opened and closed freely by being supported on the hinge, and is normally closed in contact with the back surface of the base frame plate using this hinged portion as a fulcrum. By this closing, the window 3 opened in the base frame plate 1 is surrounded all around in cooperation with the cover 6 and case 7 of the ball supply gutter 5 described above, and this enclosure and the base frame plate are bent. A safe ball collection chamber 49 is formed by the game board 10 fitted from the front and a back cover 48 to be described later.

The back cover 48 is formed to match the size of the safe ball collection chamber 49 surrounded by the cover 6, the case 7, and the mechanism frame 9. It is fixed to the mechanism frame by screwing one side edge to a mounting piece 50 protruding along the line, and the back side of the safe ball gathering chamber 49 can be opened and closed as the mechanism frame is opened and closed. It's like this.

In the figure, reference numeral 51 denotes a stop plate that locks the free edge of the back cover 48, which opens and closes, in a closed state, and 52 is a box for a control electric circuit for operating the winning device attached to this stop plate.

The stop plate 51 is rotatably attached to a pivot joint 53 provided on the inner side surface of the case 7, and when the mechanism frame is closed, the free edge of the back cover 48 is brought into contact with the inner side surface of the case 7. When it comes into contact with the receiving piece 54 protruding from the rear cover, the back cover can be restrained by overlapping the pivoting part 53 on the fulcrum, and the electric circuit box 52 is held against the stop plate 51. It is detachably fixed with screws, and when the winning device installed on the game board 10 is changed with the replacement of the game board 10, it can be easily replaced with a box equipped with a circuit corresponding to the winning device.

Reference numeral 55 is a locking device according to the present invention which restricts the opening of the mechanism frame 9 when it is closed.

As shown enlarged in FIGS. 5 to 7, this locking device 55 includes a rotating locking plate 57 that is rotatably supported by a support shaft 5b at the upper part of the outlet of the ball supply gutter 5 fixed to the base frame plate 1. , moves up and down along the guide 58' in conjunction with the rotation of this lock plate, and the ball supply gutter 5
It consists of a stopper member 58 that opens and closes the outlet. The rotating lock plate 57 has an oblique long hole 59 formed in the substantially fan-shaped plate part, and a boss-like protrusion 60 of the stopper member 58 is slidably connected to this long hole, and when locked, the handle 61 stand up vertically and attach a part of the lock plate 57 to the ball supply gutter 5.
It projects forward and engages with an engaging portion 62 provided at the upper free end of the mechanism frame 9, which is abutted against the tip of the supply gutter, thereby restraining its opening.

FIGS. 5 and 6 show this restrained state. At this time, the stopper member 58 rises and lifts its lower end from the outlet of the ball supply gutter 5, opening the prize ball guiding path 14 of the mechanism frame 6 facing this exit. We will communicate.

Next, when the handle 61 is tilted to the right in this state, the protruding portion of the lock plate 57 retreats from the engagement portion 62 of the mechanism frame, disengages it, and at the same time frees the mechanism frame to open. , a boss 6 into which the oblique elongated hole 59 slides as the lock plate 57 rotates.
0, the stopper member 58 descends, closing the ball supply gutter 5 and stopping the flow of the prize balls stored (FIG. 7).

That is, the locking device 55 equipped with the stopper member 58 normally restrains the mechanism frame 9 in the closed state, and connects the supplementary ball guide path 14 to the ball supply gutter 5 fixed to the back surface of the base frame plate to store the balls. The ball is set to be able to be supplied to the winning ball device, and when the mechanism frame is released from the back of the base frame plate 1 if necessary, the lock plate 57 is rotated to disengage from the engaging portion 62 and the ball is released. At the same time, the stopper member 58 is lowered to close the ball supply gutter 5, thereby preventing balls from flowing out from the gutter, which opens when the mechanism frame is opened.

In addition, in the figure, 63 is a prize ball discharge path 17 in a prize ball tray attached to the front of the base frame board 1, a discharge port opened in the base frame board for sending out prize balls released through the window 25, and 64 is a discharge port opened in the base frame board 10. A through hole is formed in the base frame plate to communicate with the out ball opening of the mechanism frame, and this through hole communicates with an out ball passage 65 provided vertically in the lower part of the mechanism frame.

By the way, in the pachinko machine configured as described above, the game board 10 is attached to the front side of the base frame board 1, and the back side thereof faces the window 3. When in use, the mechanism frame 9, which is attached to the back of the base frame plate via a hinge part so as to be freely openable and closable, is always closed so that the locking plate 57 of the locking device 55 is engaged with the engaging part 62. , the prize ball guide path 14 and the ball supply gutter 5 are connected to each other by being restrained in a closed state, and the stored prize balls from the storage tank 4 are guided to the prize ball case 15 through the guide path 14, while the safe ball path 27 is made to be safe. It faces the ball room 49. At the same time, in the embodiment described above, the back cover 48, which is integrally screwed to the mechanism frame 9, is placed over the back of the safe ball-closing chamber 49 to make this chamber into a sealed chamber, and its free edge is provided on the cover 7. It comes into contact with the receiving piece 54, and the stop plate 51 is placed over the overlapping portion and clamped between the receiving piece and the back cover, thereby restraining the back cover.

The present invention is constructed as described above, and the mechanism frame 9, which is attached to the back surface of the base frame plate 1 so as to be freely openable and closable with the hinge part as a fulcrum, is closed to the back surface of the base frame body, and then the locking device is closed. By rotating the lock plate 57 of 55, the release can be restrained, and at the same time, the stopper member 58 rises with this rotation operation, and the ball supply gutter 5
Balls are automatically supplied to the winning ball device in order to open the device, while when it is necessary to open the device for maintenance, inspection, repair of a malfunction, etc. inside the mechanism frame, the locking plate 57 can be rotated. At the same time as the lock state is released, the stopper member 58 closes the outlet of the ball supply gutter 5, so that the balls guided through this gutter will not fall, and during the opening operation, the balls in the storage tank cannot be pulled out. Moreover, this opening/closing operation can be performed simply by rotating the lock plate, making it extremely easy and quick.

In addition, in the case of the above embodiment, the back cover 4 is attached to the mechanism frame.
8 is integrally attached, and its free end is fixed by a stop plate 51, but this stop plate 51 can be released from its fixation by rotating around the pivoting part 53, so there is no problem at all in terms of work.
