To provide an opening/closing body driving mechanism, using an easy control method, capable of suppressing "fluttering" of an opening/closing body.SOLUTION: An opening/closing driving mechanism includes a base body, an opening/closing body, a driving unit for driving the opening/closing body, a control unit for controlling the drive of the driving unit, and a movement detection unit for detecting movement of the opening/closing body. A fall prevention control for preventing the opening/closing body from falling by the control unit controls the drive of the driving unit such that a target moving speed for determining a target moving speed of the opening/closing body is compared with an actual moving speed of the opening/closing body obtained based on information of the movement detection unit, and feedback control for controlling the drive of the driving unit is performed so that the actual moving speed of the opening/closing body becomes the target moving speed; and if the feedback control reduces the moving speed of the opening/closing body when the opening/closing body moves faster than the target moving speed by external force while the opening/closing body moves in the opening direction from the closed position, the feedback control is reset so that the actual moving speed of the opening/closing body becomes the target moving speed by comparing the actual moving speed of the opening/closing body with the target moving speed.SELECTED DRAWING: Figure 3 【課題】開閉体の「ばたつき」を抑制できる容易な制御方法を用いた開閉体駆動機構を提供する。【解決手段】開閉駆動機構は、基体と、開閉体と、開閉体を駆動する駆動部と、駆動部の駆動を制御する制御部と、開閉体の移動を検知する移動検知部とを備えた開閉体駆動機構であって、制御部による開閉体の落下を防止する落下防止制御は、開閉体の目標となる移動速度を定めた目標移動速度と移動検知部の情報に基づいて得られた開閉体の実際の移動速度とを比較して、開閉体の実際の移動速度が目標移動速度となるように駆動部の駆動を制御するフィードバック制御を行い、開閉体が閉位置から開方向へ動く際に、外力によって開閉体が目標移動速度よりも速く移動した際に、フィードバック制御によって開閉体の移動速度が減速したときに、フィードバック制御をリセットし、実際の開閉体の速度と目標移動速度とを比較して開閉体の実際の移動速度が目標移動速度となるように駆動部の駆動を制御する。【選択図】図３
