Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to a system for collecting spilled balls from a pachinko machine, which effectively collects and processes spilled balls from a prize ball tank and is useful for managing and controlling the pachinko machine. This concerns the back cover.

(Prior Art) Conventionally, in pachinko parlors, pachinko machines are centrally managed by installing a hall computer for management and transmitting game data from each pachinko machine to this hall computer. As game data,
For example, the number of supply balls, safe balls, or prize balls that would be a loss for a pachinko game parlor, and the number of batted balls or out balls that would be profitable for a pachinko game parlor, and based on these loss data and profit data. The management of each pachinko machine is performed in the following manner.

To explain a specific example, for example, in the past, as shown in FIG. A supply ball detector 104 that transmits a data signal is provided, and a pachinko machine installation island 100 below each pachinko machine 102 is used for counting to catch balls (out balls, safe balls) ejected from each pachinko machine 102. A hit ball detector 10G is installed in the tank 105 of the Kunku 105 that transmits a data signal when the hit ball passes,
The supply ball detector 104 and the hitting detector 106 are connected to the hall computer 107, and the ball hitting rate (division) of each pachinko machine 102 is obtained from the supply ball data and the batted ball data.

[Problem to be solved by the invention]

By the way, in the case of this conventional method of managing the ball exit rate using supply ball data and batted ball data, if the balls supplied to each pachinko machine 102 pass through the supply ball detector 104 and spill outside, the spilled balls will be removed from the hole. This resulted in the computer 107 processing it as lost data, and as a result, there was a problem in that a counting error occurred in the supply ball data and the batted ball data, making it impossible to obtain an accurate ball launch rate.

In addition, the counting tank 105 that receives the balls discharged from each pachinko machine 102 has its opening upper surface connected to the pachinko machine 1.
It is attached to the pachinko machine installation island 100 in a state where it is located below the discharge part of the machine 02. However, due to the installation space, only tanks with shallow bottoms can be used, resulting in the problem that falling balls bounce off the bottom and fly out.

Therefore, an object of the present invention is to provide a back cover for collecting spilled balls of a pachinko machine that can reliably collect balls that spill out from a prize ball tank in each pachinko machine and process the spilled balls as data. It is.

Another object of the present invention is to provide an integral structure of the back cover and the counting tank as described above, so as to effectively prevent balls from spilling from the counting tank.

This is an integrated system with a hit ball detector for detecting balls flowing down.

[Effect]

The back cover for collecting spilled balls configured as above is
It is installed facing the back of each pachinko machine.

Balls spilling out from the prize ball tank of the pachinko machine are caught by a box-shaped cover formed at the top of the back cover and guided to the tank at the bottom.

On the other hand, the shot balls ejected from the pachinko machine are received by the tank part along with the spilled balls, and fall downward through the passage part and the shot ball detector, and the ball is transmitted from the shot ball detector. The hit ball signal is transmitted to the hall computer and stored as profit data.
