Title:
ローラー駆動伝達装置、およびこれを備えた自動原稿搬送装置、画像形成装置
Document Type and Number:
Japanese Patent JP6477539
Kind Code:
B2
Abstract:
A roller drive transmission device includes a drive input gear, a drive transmission gear, a roller unit and a ratchet mechanism. When a rotational drive force is input to the drive input gear and the drive transmission gear is slid to a first position, the drive input gear, the drive transmission gear and the roller unit are integrally rotated in a first rotational direction. When the input of the rotational drive force to the drive input gear is cut off and the roller unit is rotated, following a sheet, the drive transmission gear is slid to a second position and the roller unit and the drive transmission gear are decoupled. The ratchet mechanism includes a load adjustment mechanism configured to make a rotational load in the first rotational direction of the drive transmission gear arranged at the second position larger than a movement load in an axial direction.
