Description

[Detailed Description of the Invention] This invention relates to an empty tray display device for a pachinko machine.

Conventionally, this type of device sends a signal generated by each ball supply contact (empty plate detection switch) of a large number of pachinko machines to a monitoring board, and when the plate becomes empty, a light bulb, light emitting diode, etc. lights up. It's summery. That is, each pachinko machine and a light bulb were formed in one-to-one correspondence, and therefore the monitoring board was provided with the same number of light bulbs as there were pachinko machines.

For this reason, the number of display bulbs increases, power consumption increases, and the display space of the bulbs also increases.
Surveillance was laborious and troublesome.

This invention was made in view of the above situation, and the structure of this invention is described with reference to the drawings. In FIG. A data selection circuit 4 that outputs an empty tray number signal and a blank signal in response to the open/closed state of each ball supply contact 1 of a large number of pachinko machines 2, and a storage circuit 5 that stores the empty tray number signal. , a shift register 10 that determines the position of the image corresponding to the empty plate stand on the screen, a character generator 9 that outputs the stand number signal of the empty plate stand, and a converter that converts the stand number signal of the empty plate stand into a video signal. This empty tray display device for a pachinko machine is characterized by comprising a video generating circuit 6 having a video control circuit 8 for controlling the number of empty trays, and a display device 7 for directly displaying the machine number of the empty tray table at a predetermined position.

In the figure, 8 is a video control circuit, 9 is a character generator, 10 is a shift register, 1
1 indicates a gate circuit.

To explain this in detail, in FIG. 2, the data selection circuit 4 selects each pachinko machine (hereinafter simply referred to as "machine") according to the control signal issued by the control circuit 3.
The open/close state of the ball supply contact 1 of No. 2 is determined, and if it is an empty plate (deficiency state), an empty plate signal is output from A in the figure, and the machine number signal is output from B. The ball supply contact 1 is a tank contact or a supply ball detection contact in a machine without a tank. In this specification, a machine with a tank will be described as an example.

If the tank is not empty, a blank signal is output from C in the figure.

12 is a code conversion circuit that changes obsolete numbers such as 4th and 9th numbers of each machine to other numbers; 13 is a code transfer circuit that also selects digits; It is input to the A' portion of the memory circuit 5 in the figure. Further, from this memory circuit 5, an address signal for generating a video signal is output from D, and a timing control circuit 15 shown in FIG.
input into D′. A machine number signal is outputted from the memory circuit 5 from E in FIG. 3 and inputted to E' of the latch 16 shown in FIG. Note that 17 in FIG. 4 indicates a reference oscillation circuit, and 18 indicates a timing pulse generation circuit. Note that 19 in FIG. 3 is a page switching circuit.

The machine machine numbers of empty and non-empty plates determined, transferred, and stored as described above are sequentially input to the character generator 9 as a number signal and a blank signal, and then passed through the shift register 10. It reaches the display device 7 and is displayed.

Note that the display device 7 may be a known display device such as a cathode tray tube or a plasma display.

An example of the form displayed by these display devices 7 is as shown in FIG. 5. That is, as shown in the same figure, for example, an address can be formed by numbers ranging from the upper left corner to the lower right corner, and this address can be a location in the same format as the conventional monitoring board, so that the conventional monitoring board can be Even if you change from a panel to this display device, the operator will not feel any discomfort. Furthermore, since the display device 7 can be a cathode tube, plasma display, etc., the monitoring area can be reduced and the monitoring work can be made extremely easy.

Since this device is configured as described above,
Since the display device 7 that directly displays only the empty plate number can be displayed at each predetermined position and the others can be left blank with no display, the monitoring can be made extremely easy to see and the fatigue of monitoring can be reduced. can do. In addition, by using a shift register 10 that determines the position of the image corresponding to the empty tray table on the screen and displaying it using a display device 7 that directly displays the image, such as a cathode tray tube, it is possible to change the appearance of the pachinko playing area. Even when the layout of a pachinko machine is changed, with the same machine number or a new machine number, the display position of the machine number on the display device 7 can be easily moved to a position that almost corresponds to the changed layout. can be displayed and can be easily monitored.
