Description

[Detailed description of the invention]

(Field of Industrial Application) The present invention is based on a large number of game machines such as pachinko machines installed in a pachinko hall, game support machines such as ball lending machines and prize exchange machines, and the operating status of each of the above machines. The present invention relates to a signal transmission device for transmitting signals to and from a management computer for managing ball output of a gaming machine, sales amount, etc. using a minimum number of cables. (Prior Art) Conventionally, pachinko balls are equipped with a large number of gaming machines such as pachinko machines and throttle machines, as well as gaming support machines such as ball lending machines and prize exchange machines. A management computer is installed to manage sales amounts, etc. This management computer is 'i! It is electrically connected to each of the game support machines such as the single-player machine, the ball lending machine, and the prize exchange machine, and centrally controls the catching and stopping of balls, the amount of balls owed, the amount of prize exchange, etc. The aim is to improve the management of pachinko halls by analyzing data on balls played based on operating signals from each gaming machine, collecting and analyzing special prize status, winning status, and operational data. . For the above purpose, each gaming machine and gaming support machine and the management monitor are connected by respective signal lines for each signal sent and received. Taking a pachinko machine with a large number of machines as an example, as shown in Figure 4, the number of out balls,
A large number of pachinko machines P1 to pn are used as counting signals a, b, and C to count safe balls and special prize states, respectively.

Pachinko machines P1 to pn need to be transmitted to the PU.
In total, at least 3n signal lines are connected to the input interface of the management computer CPU, and when there are many pachinko machines, the total number of signal lines becomes enormous. Therefore, a large wiring space for the 8 wires is generally required in the ceiling of a pachinko hall, and a huge amount of manpower and time is required for wiring work or wiring inspection work. In addition, when attempting to transmit new additional information such as winning information from each pachinko machine P1 to Pn to the management computer CPU in order to improve the gaming performance of the gaming machine, the number of signal lines will further increase. This increases the wiring space and requires additional input interfaces for the management computer, which increases the cost of pachinko halls. (Problems to be Solved by the Invention) As described above, in the conventional gaming machine and the management computer, signal transmission is performed via a huge number of signal lines connected for each transmission signal. In the case of a pachinko hall where a large number of gaming machines are installed, the number of signal lines becomes enormous, which increases the cost of electrical work or electrical inspection. Therefore, in the present invention, the number of signal lines can be reduced by transmitting signals between the gaming machines in a pachinko hall and the management combination 1 using a serial signal 3. By significantly reducing the cost of electrical work or electrical inspection, and making it possible to cope with future increases in traffic signals,

After inputting multiple operating signals output from each gaming machine,
a transmitter that converts each input operation signal into a serial signal and outputs the serial signal; a signal line that transmits the serial signal output from the transmitter; and a receiver that receives the serial signal transmitted via the signal line. In addition, the configuration includes a receiving device installed near the management computer that demodulates the serial signal into the plurality of operating signals and outputs them to the management computer. (Function) According to the signal transmission device in a pachinko hall having the above configuration, the transmitting device installed near the gaming machines transmits a plurality of operating signals output from each gaming machine in accordance with the operation of each gaming machine. For example, it inputs counting signals for out balls, safe balls, and special prize states, and then converts each input signal into a serial signal and outputs it. The serial signal is transmitted via a signal line to a receiving device installed near the management computer. When the receiving device receives the serial signal, it demodulates the serial signal into the respective operating signals and outputs them to the management computer. Each count signal is input, each is counted, and the operating state of the entire gaming machine is analyzed based on each power runt data. (Example) Next, an example of the present invention will be described with reference to the drawings. Figure 1 shows n pachinko machines P in a pachinko hall.

For example, signals a, b, and C are sent to the transmitting devices T1, T2, at the timing shown in FIG. 0. When input to each of Tn, the converted serial signal d is sent to the transmitting devices 1TI, T210 . . According to the input order for each Tn, a signal ta having a pulse width corresponding to the signal a is first generated, then after an interval time tx a signal tc having a pulse width of 4i corresponding to the signal 3C is generated, and then a signal tc having a pulse width corresponding to the signal 3C is generated after an interval time tx. A signal tb having a pulse width corresponding to the signal s is generated through the process, and thereafter the signal ta is generated in the same manner. tb and tC are generated serially.
