Abstract
A sheet separating mechanism includes a separation claw arranged on the surface of a rotatable member such that the separation claw can be rotated around a shaft of the rotatable member with which a claw portion can be brought into slidable contact. A holder rotatably holds the separation claw through the rotating shaft, the holder being rotatably arranged on an attaching portion of the body of the apparatus. A leaf spring elastically holds the holder at a predetermined position when the holder is attached to the attaching portion.
Claims12
A sheet separating device, comprising:
- a claw disposed opposite a roller and configured to separate a recording medium from the roller;
- a first retaining member configured to retain the claw and to permit the claw to rotate relative to the first retaining member;
- a second retaining member configured to retain the first retaining member and to permit the first retaining member to rotate relative to the second retaining member, and
- a biasing member disposed between the first and second retaining members to bias the first retaining member away from the second retaining member,
- wherein each of the first retaining member and the second retaining member comprises contact sections configured to contact one another to limit the rotation of the first retaining member relative to the second retaining member due to the biasing member.
An image forming apparatus, comprising:
- a fixing device including a fixing roller;
- a claw disposed opposite the fixing roller and configured to separate a recording medium from the fixing roller;
- a first retaining member configured to retain the claw and to permit the claw to rotate relative to the first retaining member;
- a second retaining member configured to retain the first retaining member and to permit the first retaining member to rotate relative to the second retaining member, the second retaining member connected to a body of the image forming apparatus, and
- a biasing member disposed between the first and second retaining members to bias the first retaining member away from second retaining member,
- wherein each of the first retaining member and the second retaining member comprises contact sections configured to contact one another to limit the rotation of the first retaining member relative to the second retaining member due to the biasing member.
A sheet separating mechanism comprising a separation claw configured to engage a surface of a rotatable member located adjacent to said separation claw, a holder configured to rotatably hold said separation claw through a rotating shaft, and a supporting section configured to rotatably support said holder, wherein said holder further comprises a leaf spring, and said supporting section further comprises a first abutting section to be abutted against said leaf spring and a second abutting section to be abutted against a part of the main body of said holder facing against said first abutting section.
