Power feeding plug locking device
First Claim
1. A power feeding plug locking device that locks a power feeding plug to a power feeding inlet, wherein the power feeding inlet is arranged in a machine, the machine including a door that can be locked, the power feeding plug locking device comprising:
- a lock mechanism including a lock member that is movable between a lock position and an unlock position and a driving device that is operable to move the lock member between the lock position and the unlock position, wherein the lock mechanism prohibits removal of the power feeding plug from the inlet when the lock member is positioned at the lock position and allows removal of the power feeding plug from the inlet when the lock member is positioned at the unlock position;
a switch which is operable by a user and which, when operated, outputs an operational signal that instructs the driving device to move the lock member between the lock position and the unlock position;
a door lock state confirmation unit that confirms whether the door of the machine is locked and outputs a door lock state signal; and
a controller communicatively coupled with the switch, the door lock state confirmation unit, and the driving device, wherein the controller controls the driving device to move the lock member from the lock position to the unlock position when the controller receives the operational signal from the switch that instructs the driving device to move the lock member to the unlock position and the door lock state signal from the door lock state confirmation unit that indicates a door unlock state of the door of the machine, wherein the operational signal is a signal different from the door lock state signal.

Abstract
A power feeding plug locking device that locks a power feeding plug to a power feeding inlet. The power feeding inlet is arranged in a machine including a door that can be locked. The locking device includes a lock mechanism of which operational state is shifted between a lock state and an unlock state. The lock mechanism prohibits removal of the power feeding plug from the inlet in the lock state and allows removal of the power feeding plug from the inlet in the unlock state. An operation unit is operated when switching the operational state of the lock mechanism between the lock state and the unlock state. A door lock state confirmation unit confirms whether the door of the machine is locked. A controller controls the operational state of the lock mechanism based on the operation of operation unit whether the door is locked.

11. A power feeding plug locking device that locks a power feeding plug to a power feeding inlet, wherein the power feeding inlet is arranged in a machine, the machine including a door that can be locked, the power feeding plug locking device comprising:
-
a lock mechanism selectively shiftable between a lock state and an unlock state, wherein the lock mechanism prohibits removal of the power feeding plug from the inlet in the lock state and allows removal of the power feeding plug from the inlet in the unlock state; an unlock switch which, when operated, outputs an operational signal that enables shifting the lock mechanism between the lock state and the unlock state; a door lock state confirmation unit that confirms whether the door of the machine is locked and outputs a door lock state signal; and a controller communicatively coupled with the unlock switch, the door lock state confirmation unit, and the lock mechanism, wherein the controller shifts the lock mechanism between the lock state and the unlock state based on the operation signal from the unlock switch and the door lock state signal from the door lock state confirmation unit, and wherein the controller shifts the lock mechanism to the unlock state when the door lock state confirmation unit confirms an unlock state of the door of the machine and the unlock switch is operated. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
