Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for supplying pachinko balls to each of pachinko machines arranged in a row.

Conventionally, pachinko balls (prize balls) were supplied to pachinko machines in rows by arranging a supply gutter at the top of the pachinko machine and communicating this with the upper tank for storing prize balls on the back of each pachinko machine. On the other hand, pachinko balls are supplied by a lifting device installed in each row of pachinko machines or in each hall.

However, since such a conventional supply device requires the supply gutter to be disposed within the curtain board at the top of the pachinko machine, there are various disadvantages as described below.

(1) Construction is difficult and costly, and it is also difficult to obtain construction accuracy and stability of maintenance after construction.

(2) Since the replenishment gutter is installed at a high place, it is difficult to take immediate action and repair when a ball replenishment problem occurs, which often causes players to feel uncomfortable.

(3) Similarly, maintenance and inspection such as parts replacement and cleaning are difficult, so problems such as bulb clogging due to moisture are likely to occur.

(4) It gets in the way of the wiring inside the curtain board, making wiring work time-consuming.

The present invention was made as a result of research in order to solve the inconveniences of the conventional equipment, and by reviewing the conventional common sense of arranging the supply gutter at the top of the row of pachinko machines, The machine is characterized in that a supply gutter is disposed at a height between the upper tank group and the lower receiving frame group of the return machine, and this supply gutter is communicated with the return machine receiving frame of each pachinko machine.

The invention will now be described with reference to the illustrated embodiments.

Pachinko machines 1 arranged in horizontal rows are each equipped with an upper tank 2 for storing prize balls at the upper part of the back side, and a return machine 3 at the lower part.
A receiving frame 3a is provided.

The rows of pachinko machines are arranged with their backs facing each other, forming a pair of two rows of pachinko islands.

The supply gutter 4 that supplies pachinko balls to each of these pachinko machines is located at a height between the row-shaped upper tank 2 group and the receiving frame 3a group in the space between the backs of the pair of rows of pachinko machines. A lifting device which is arranged in a container and which allows pachinko balls supplied therein to flow down by gravity.

An appropriate slope downward from 10 is given.

In addition to using a series of long replenishment troughs 4 for each row of pachinko machines, a series of replenishment troughs 4 can be formed by appropriately connecting troughs with a length spanning one or more pachinko machines 1.

The supply gutter 4 and the receiving frame 3a of each pachinko machine 1 are connected by a connection gutter 5, respectively.

The connection gutter 5 has its upper end communicated with the supply gutter 4 and its lower end simply suspended within the receiving frame 3a, and a passage space 6 for pachinko balls is formed between the connecting gutter 5 and the bottom surface of the receiving frame 3a.

Therefore, when the supply gutter 4 and the connecting gutter 5 are filled with pachinko balls, the pachinko balls naturally flow down from the passage space 6 into the receiving frame 3a, and the pressure of the balls stored in the receiving frame 3a and the flow of the balls in the connecting gutter 5 When the pressure balances, the flow stops.

Of course, it is possible to limit the amount of pachinko balls supplied to the tray by providing a flow path opening/closing valve in the connection gutter 5, but if the supply device uses gravity flow as described above, the configuration is extremely simple. There is an advantage that a certain number or more of pachinko balls can always be secured in the receiving frame 3a, and troubles such as ball jamming are less likely to occur.

Therefore, the reducing machine 3 having the receiving frame 3a below has the receiving frame 3a
The pachinko balls inside are guided to the upper tank 1 via the ball outlet 3b.

As long as the reducing machine 3 has this reducing function, it does not matter whether it has a structure in which the balls are pushed up by a sprocket or a structure in which the balls are lifted by a basket supported on a chain.

Note that in the lower space between the pair of pachinko machine rows that make up the pachinko machine row, a collection gutter 8 that is inclined toward the lifting device 10 is provided, and the lifting device 10 transfers the collected pachinko balls to a tank 9.
or directly to the supply trough 4.

The lifting device 10 can be provided commonly to a plurality of pachinko islands as shown in FIG. 1, or provided for each pachinko island as shown in FIG.

Therefore, in this device having the above configuration, when the number of prize balls in the upper tank 2 of a specific pachinko machine 1 decreases as a result of a pachinko game, the ball shortage detector 11 provided on the bottom of the upper tank 2 detects this, and the reduction machine Drive 3.

This return machine 3 is driven only when the ball detector 12 on the lower surface of the receiving frame 3a detects that there is a ball in the receiving frame, so that prize balls are reliably transported and replenished to the upper tank.

When the number of pachinko balls in the receiving frame 3a decreases, they are automatically replenished to a certain level from the connection gutter 5 and the supply gutter 4 as described above.

The number of refills to the upper tank 2 can be managed by, for example, providing a counter at the entrance or exit of the reducing machine 3.

Further, out balls may be collected in the receiving frame 3a and overflowing balls may be dropped into the collection gutter 8, or they may be directly dropped into the collection gutter 8.

The number of out balls is counted by similarly providing a counter at the out ball exit or the overflow ball opening of the receiving frame 3a.

In FIG. 3, reference numeral 13 indicates a discharge gutter used for discharging the balls in the receiving frame 3a, and reference numeral 14 indicates a counter provided therein.

According to the pachinko ball supply device of the present invention described above, the following effects can be obtained.

(1) Since the supply gutter is installed between the upper tank and the lower saucer of the pachinko machine, construction is easy, construction accuracy is high, and costs can be reduced.

(2) The curtain plate above the pachinko machine, where the supply gutter was conventionally installed, can now be used for other purposes; for example, a television can be installed here, or wiring for the pachinko machine can be installed here.

In particular, the supply gutter will not become overloaded during wiring.

(3) Since the installation position of the replenishment gutter is lower, it is possible to quickly repair the ball replenishment problem if it occurs.

(4) For the same reason, maintenance inspection and cleaning are easier, and therefore troubles caused by dust adhesion and moisture are less likely to occur.
