Abstract
Provided is a saddle stitch folding apparatus including: a stitcher unit; a reel support unit configured to support a reel rotatably about the axis with a support shaft being inserted in a through-hole formed in the reel; and a rotation detecting mechanism configured to detect a rotation state of the reel, and the rotation detecting mechanism has an adhering member that is rotated while adhered to a bottom face of the reel, a rotating member having an insertion hole inserted in the support shaft, and a rotation detecting unit configured to detect the rotation state of the rotating member.
Claims11
A sheet bundle binding apparatus comprising:
- a stitcher unit configured to perform a binding operation of binding a sheet bundle using a wire at a predetermined binding position;
- a reel support unit configured to support a reel rotatably about an axis with a support shaft extending along the axis being inserted in a through-hole formed in the reel on which the wire is wound;
- a rotation detecting mechanism configured to detect a rotation state of the reel;
- and
- a wire feed unit configured to perform a supply operation of unwinding the wire from the reel to supply the wire to the stitcher unit,
- wherein the rotation detecting mechanism has
- an adhering member rotated about the axis together with the reel while adhered to a bottom face of the reel,
- a rotating member connected to the adhering member rotatably about the axis together with the adhering member and having an insertion hole into which the support shaft is inserted, and
- a rotation detecting unit configured to detect a rotation state of the rotating member.
A rotation detection method for detecting rotation of a reel used for a sheet bundle binding apparatus, wherein the sheet bundle binding apparatus has
- a stitcher unit configured to perform a binding operation of binding a sheet bundle using a wire at a predetermined binding position;
- a reel support unit configured to support a reel rotatably about an axis with a support shaft extending along the axis being inserted in a through-hole formed in the reel on which the wire is wound;
- a rotation detecting mechanism configured to detect a rotation state of the reel;
- and
- a wire feed unit configured to perform a supply operation of unwinding the wire from the reel to supply the wire to the stitcher unit,
- wherein the rotation detecting mechanism has
- an adhering member rotated about the axis together with the reel while adhered to a bottom face of the reel, and
- a rotating member connected to the adhering member rotatably about the axis together with the adhering member and having an insertion hole into which the support shaft is inserted,
- the rotation detection method comprising a rotation detecting step of detecting a rotation state of the rotating member.
