A pressure sensor 207 is connected to the lower end of the pressure tank 205 to monitor the pressure inside the pressure tank 205. The controller 405 controls the first relay driver 403 to turn on / off the operation of the air compressor 401, turn on / off the air compressor 401, and maintain a constant pressure in the pressure tank 205. To be maintained. In addition, the control unit 405 controls the second relay driver 409 when the firing switch 411 is pressed to open the pressure valve 203 for a predetermined time, and is inserted into the water shell 201 deep in the water shell 201 ( The compressed water is injected into the 103 so that the water shell 201 is fired. The controller 405 opens the pressure valve 203 for a predetermined time according to the event signal provided from the timer 413, and then closes the pressure valve 203 again so that pressure does not flow out. The control program of the controller 405 is stored in the memory 415. The analog pressure signal sensed by the pressure sensor 207 is converted into a digital signal through the A / D converter 407 and transmitted to the controller 405. The controller 407 increases the pressure of the pressure tank 205 by operating the air compressor 401 when the pressure value falls below a predetermined predetermined value, and operates the air compressor 401 when the pressure reaches a predetermined value or more. To stop.
