An elevator control device having an operation control unit to control operation of an elevator in accordance with an operation mode selected by a selector switch installed at an upper part of an elevator car , the elevator control device further comprising: a maintenance worker boarding/leaving judgment unit to judge whether a maintenance worker boards or leaves the elevator car on the basis of a signal from a governor encoder for detecting a travel distance of the elevator car in a hoistway ; and a switch operation permission unit to permit the operation control unit to operate in an operation mode selected by the selector switch on the basis of a state where the maintenance worker boards or leaves the elevator car judged at the maintenance worker boarding/leaving judgment unit ; characterized in that : the elevator control device further comprises a platform door open/close judgment unit to judge an open or close state of a platform door on the basis of a signal from a platform door open/close detector installed at a platform door of the hoistway , and the switch operation permission unit permits the operation control unit to operate in a normal mode when the operation mode is switched from a maintenance mode to the normal mode by the selector switch in a state where the maintenance worker boarding/leaving judgment unit judges that a maintenance worker has left the elevator car and when the platform door open/close judgment unit judges that the platform door has changed from an open state to a close state in a state where the maintenance worker boarding/leaving judgment unit judges that a maintenance worker has left the elevator car . a maintenance worker boarding/leaving judgment unit to judge whether a maintenance worker boards or leaves the elevator car on the basis of a signal from a governor encoder for detecting a travel distance of the elevator car in a hoistway ; and a switch operation permission unit to permit the operation control unit to operate in an operation mode selected by the selector switch on the basis of a state where the maintenance worker boards or leaves the elevator car judged at the maintenance worker boarding/leaving judgment unit ; characterized in that : the elevator control device further comprises a platform door open/close judgment unit to judge an open or close state of a platform door on the basis of a signal from a platform door open/close detector installed at a platform door of the hoistway , and the switch operation permission unit permits the operation control unit to operate in a normal mode when the operation mode is switched from a maintenance mode to the normal mode by the selector switch in a state where the maintenance worker boarding/leaving judgment unit judges that a maintenance worker has left the elevator car and when the platform door open/close judgment unit judges that the platform door has changed from an open state to a close state in a state where the maintenance worker boarding/leaving judgment unit judges that a maintenance worker has left the elevator car . the elevator control device further comprises a platform door open/close judgment unit to judge an open or close state of a platform door on the basis of a signal from a platform door open/close detector installed at a platform door of the hoistway , and the switch operation permission unit permits the operation control unit to operate in a normal mode when the operation mode is switched from a maintenance mode to the normal mode by the selector switch in a state where the maintenance worker boarding/leaving judgment unit judges that a maintenance worker has left the elevator car and when the platform door open/close judgment unit judges that the platform door has changed from an open state to a close state in a state where the maintenance worker boarding/leaving judgment unit judges that a maintenance worker has left the elevator car . <EOS>
