Abstract
A door control device is adapted to smoothly shift the mode of operation to the door closer operation at the time the door is being moved by pushing in the door closing condition, without requiring a large size motor and without the need for increasing the strength of the drive medium. The door control device includes a closer for shifting a slide door from the half door condition to the fully closed condition, and a clutch mechanism which is interposed in a power transmission system between the slide door and a motor for driving the slide door. If the slide door is electrically driven, a clutch of the clutch mechanism is rendered operational to move the slide door and the closer operation is started after the sliding operation. The door control device further includes a pole switch which detects the condition of the slide door and a junction switch which establishes the connection when the condition of the slide door is between a condition right before the half door condition and the fully closed condition, and effects the supply of electricity to the closer. If the junction switch is connected in the midst of the closing operation of the slide door, the closer operation is started and then the motor is stopped when the slide door is moved a given distance.
