It won't work like this. Pachinko machines that are old enough to not have tamper protection all use two wire ball sensors, so you'd need to design an interface circuit to convert between the output of your three wire sensor and the input of the pachinko that is designed for a two wire sensor, and if you need to design an interface circuit, then you might as well just use a simple switch as the input to your circuit.

Even if you used an identical two wire sensor as is used in the pachinko machine, they're not designed to be connected in parallel. The two wire sensor takes a specific amount of power from the ball detection circuit in the pachinko machine, when a ball passes through the sensor, the amount of power taken changes significantly, and this is detected by the input circuit. If you put a second sensor in parallel, the power levels will not match what the input circuit is designed to detect, and it simply won't work. If you put a regular switch in parallel, then when triggered this will affect the amount of power available to the original sensor, and it will behave unpredictably until it's power supply has stabilised.

It can be done (on the 15+ year old machines that do not have a second sensor for tamper protection), the simplest method is to trace the signal from the sensor through the input circuit on the pachinko, and add your cheat switch after the signal has been converted to a regular logic level signal, but don't be surprised if you still get alarms and error codes if your button is pressed for a longer or shorter duration than the pachinko expects for a ball passing through the sensor.
