It is determined whether or not it is equal to the group number. If the number is equal to the group number, a signal for controlling the driving of the drive unit 88 is transmitted, and the motor 20 is driven to rotate. For example, the motor 20 is controlled to rotate in the winding direction of the elevating tape 18 when the slat lifting is instructed, and the rotation of the motor 20 is stopped when the slat stop is instructed.
Further, when the slat descent is instructed, the motor 20 rotates in the unwinding direction of the elevating tape 18, and when the slat stop is instructed, the rotation of the motor 20 is controlled to stop. When the slat forward rotation is commanded, the motor 20 rotates in one direction, and when the flat reverse rotation is commanded, the motor 20 rotates in the opposite direction. As a result, the elevation height of the slats 12 belonging to a desired unit or group and the rotation angle of the slats 12 can be set to a desired state.
