POWER TURNING-OFF CONTROLLER AT WINDOW SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a power turning-off controller at a window system which does not erroneously stop power supply to a cash processor under local operation even when turning off the power source switch of a window processor being a host device without confirming the state of the cash processor being a slave device and which automatically stops power supply in a state where local operation is finished and there is no problem even if power supply is stopped. SOLUTION: The controller is provided with an operation state detection part 33 which monitors the operation state of the cash processor 11 and outputs a power turning-off consenting signal showing the message that there is no problem when the pertinent cash processor 11 is in the state of having no problem even if power supply is stopped. The controller is also provided with a power supply control part 36 which turns off the power source of the cash processor 11 on condition that the power turning-off consenting signal is outputted from the operation state detection part 33 when a power turning-off signal outputted from the window processor 10 at the time of turning off the power source.
