A pachinko machine unlocking device that has a structure that unlocks the locking hook on the glass frame side, and has a large number of switches corresponding to each pachinko machine on a control panel installed in a prize exchange area or control room. is proposed.

<Problems to be Solved by the Invention> This type of pachinko machine unlocking device unlocks the glass frames of each pachinko machine individually on a control panel in a management room, or sequentially unlocks the glass frames of all pachinko machines. However, since there are at least 100 or more pachinko machines installed in one amusement hall, and as many as 200 or 200 pachinko machines, there is a control board for each pachinko machine. A large number of corresponding switches and changeover switches were lined up, resulting in an extremely large control panel and the problem of making it easy to operate the switches incorrectly. Furthermore, the above-mentioned unlocking device is provided with a sequential unlocking mechanism that unlocks each pachinko machine in sequence.
This sequential unlocking mechanism turns on multiple microswitches in sequence while rotating the drum, so it requires a very large drum to unlock many pachinko machines, and the machine The problem was that there were many moving parts, which led to many breakdowns. Additionally, as the number of pachinko machines increases, the number of wires connecting the control panel in the management room and each pachinko machine increases, resulting in thicker and heavier wiring cables, which requires more space and larger wiring equipment. There were also issues such as the need to do so.

The purpose of the present invention is to provide an unlocking control device for a pachinko machine that does not have any problems, has thinner and lighter wiring cables between each pachinko machine and the control panel, and has fewer failures and improves the operability of the switch.
It is configured as follows.

That is, the unlocking control device for a pachinko machine of the present invention allows each unlocking device of a large number of pachinko machines equipped with a glass frame unlocking device and a wooden frame unlocking device operated by a solenoid to be installed separately. An unlocking control device for a pachinko machine that is operated from a control panel includes a numeric key switch that outputs a BCD code signal corresponding to each pachinko machine, a glass frame switch that outputs a signal for unlocking the glass frame, and a wooden frame. A group of switches including a wooden frame switch that outputs an unlocking signal, and a full-open switch that outputs a signal that sequentially unlocks all pachinko machines, and a group of switches that input the BCD code signal from the numeric keypad switch and output the number indicated by the BCD code. A transmission circuit that serially outputs a pulse signal, and an optical conversion circuit that converts the pulse signal from the transmission circuit into light and outputs it are installed in the control panel, and are connected to the optical conversion circuit via an optical fiber. A light receiving circuit inputs the optical signal from the optical conversion circuit and converts it into an electrical signal, and a waveform shaping circuit inputs the signal sent from the light receiving circuit, counts the number of pulse signals, and determines the type and analysis of the signal. A signal discrimination circuit for determining a pachinko machine to be locked and outputting a signal or a full open signal indicating whether the pachinko machine to be unlocked is a glass frame unlocking device or a wooden frame unlocking device; It has a circuit that corresponds to the unlocking device and the wooden frame unlocking device, and amplifies the signal output from the signal discrimination circuit to each circuit, and it can be used as a glass frame unlocking device or a wooden frame unlocking device for each pachinko machine. When a full open signal is input from the output circuit that outputs a one-shot signal to the drive circuit for energizing the solenoid of the machine, and the signal discrimination circuit, the pulse signal is sequentially sent to each circuit corresponding to each pachinko machine in the output circuit. A shogi knockdown circuit that outputs and generates the next pulse signal in synchronization with the falling edge of the pulse signal is provided in a sub-control panel near each pachinko machine, and the drive circuit in the sub-control panel is connected to each pachinko machine. It is connected to the solenoid of the glass frame unlocking device and the wooden frame unlocking device.

Next, the operation of the pachinko machine unlocking control device having the above configuration will be explained.

When unlocking the glass frame of a specific pachinko machine,
First, the number of the pachinko machine is specified using the ten key switch 10 on the control panel 1. Then, the BCD code of the numerical value operated by the key from the ten-key switch 10 is sent to the transmitting circuit 14 and the display circuit 16, and the number of the pachinko machine is displayed on the display 17.

Furthermore, by using the shogi knockdown circuit 25, it is possible to automatically unlock the glass frame and wooden frame of all pachinko machines one after another by operating one or two switches, and the circuit for this purpose is contactless and smaller than before. It becomes possible to

In addition, the Shogi knockdown circuit generates the unlocking pulse signal in synchronization with the fall of the previous pulse signal to create the next pulse signal, and in order to send it to the output circuit, it energizes the unlocking solenoid. Time,
The pulse width can be set arbitrarily (for example, very short, like 10-odd milliseconds), and each signal can be output in sequence without any delay, allowing all pachinko machines to be unlocked quickly and sequentially. .

In addition, since the control panel and each sub-control panel are connected by optical fiber, the number of wiring cables can be extremely thin and lightweight in amusement facilities with many pachinko machines, which reduces the space required for installation and wiring equipment. In addition to being able to reduce the size of the device, noise is less likely to enter the signal line, and malfunctions due to noise can be prevented.
