Summary:To provide a geared motor drive control mechanism that executes a stopping operation between a start point and an end point of a drive range, maintains the stopping operation, and can execute each operation starting from the stopped state smoothly and reliably without applying any external force other than the drive input of an electric motor.SOLUTION: In a geared motor drive control mechanism, brake means 4 includes a rotating portion 40 including a plurality of permanent magnets 43 and a fixed portion 41 including a plurality of other permanent magnets 45, and one permanent magnet 43 of the rotating portion 40 and the other permanent magnet 45 of the fixed portion 41 are arranged at equal intervals with their polarities aligned in the radial direction centering on a drive shaft 21, and in the driving state of the geared motor, the magnetic coupling between one permanent magnet 43 of the rotating portion 40 and the other permanent magnet 45 of the fixed portion 41 is released, and in the stopped state of the geared motor, the magnetic coupling is formed between one permanent magnet 43 of the rotating portion 40 and the other permanent magnet 45 of the fixed portion 41.SELECTED DRAWING: Figure 3 【課題】駆動範囲の始点から終点までの間における停止動作を実行し、この停止動作を維持し、かつこの停止状態から始動する各動作を、電動モータの駆動入力以外の外力を付与することなく円滑かつ確実に実行できるギヤードモータの駆動制御機構を提供する。【解決手段】ギヤードモータの駆動制御機構は、ブレーキ手段４が、複数の一の永久磁石４３を含む回転部４０と、複数の他の永久磁石４５を含む固定部４１とを備え、回転部４０の一の永久磁石４３及び固定部４１の他の永久磁石４５が、駆動軸２１を中心とする径方向に極性が整列されて等間隔に配列され、ギヤードモータの駆動状態では、回転部４０の一の永久磁石４３と固定部４１の他の永久磁石４５間の磁気結合が解除され、ギヤードモータの停止状態では、回転部４０の一の永久磁石４３と固定部４１の他の永久磁石４５間に磁気結合が形成される。【選択図】図３
