Abstract

A binding apparatus includes: a set of binding parts configured to press and bind a bundle of recording materials from one side and a remaining side in a thickness direction; a first support part configured to support the bundle of recording materials from the one side by performing rotation toward the bundle of recording materials around a predetermined fulcrum; and a second support part configured to support the bundle of recording materials from the remaining side so as to face the first support part when binding is performed by the set of binding parts.

First claim

What is claimed is:

1 . A binding apparatus comprising:
a set of binding parts configured to press and bind a bundle of recording materials from one side and a remaining side in a thickness direction; a first support part configured to support the bundle of recording materials from the one side by performing rotation toward the bundle of recording materials around a predetermined fulcrum; and a second support part configured to support the bundle of recording materials from the remaining side so as to face the first support part when binding is performed by the set of binding parts.

2 . The binding apparatus according to claim 1 , further comprising a regulating mechanism configured to regulate a relative movement between the first support part and the binding part on the one side, wherein
the movement of the first support part and the binding part on the one side is relatively regulated by the regulating mechanism.

3 . The binding apparatus according to claim 2 , wherein
the regulating mechanism is provided to link the first support part with the binding part on the one side in such a manner that the first support and the binding part are movable together, the predetermined fulcrum is provided on one end of the regulating mechanism, and a remaining end of the regulating mechanism is provided with the first support part and a transmission groove configured to transmit the movement of the binding part on the one side to the first support part.

4 . The binding apparatus according to claim 3 , wherein
the set of binding parts moves with respect to another fulcrum in a pressing direction having a component orthogonal to an entry and exit direction where the recording material or the bundle of recording materials enters and exits, and the transmission groove is formed along a direction having a component in the entry and exit direction.

5 . The binding apparatus according to claim 2 , wherein
the regulating mechanism further includes a regulating groove configured to regulate the movement of the binding part on the one side before the first support part comes into contact with the bundle of recording materials.

6 . The binding apparatus according to claim 5 , wherein
the regulating groove regulates a movement of the binding part on the one side to a downstream side in an entry and exit direction where the recording material or the bundle of recording materials enters and exits, when the binding part on the one side comes into contact with the bundle of recording materials after the first support part pushes the bundle of recording materials.

7 . The binding apparatus according to claim 5 , wherein
the first support part is configured to push the bundle of recording materials and then retreat in a direction far away from the bundle of recording materials when the binding part on the one side comes into contact with the bundle of recording materials.

8 . The binding apparatus according to claim 5 , wherein
the regulating groove is provided and connected to a transmission groove at an end portion more distal than the transmission groove that transmits the movement of the binding part on the one side to the first support part.

9 . The binding apparatus according to claim 5 , wherein
the regulating groove is formed along a direction having a component in a pressing direction that is orthogonal to an entry and exit direction where the recording material or the bundle of recording materials enters and exits.

10 . The binding apparatus according to claim 9 , wherein
a transmission groove that transmits the movement of the binding part on the one side to the first support part is formed downstream of the regulating groove with respect to the entry and exit direction where the recording material or the bundle of recording materials enters and exits, a most upstream end of the transmission groove in the entry and exit direction is connected to an uppermost end of the regulating groove in the pressing direction, and when the binding part on the one side moves toward a binding position along a binding path, a pressing direction movement having a component in the pressing direction is regulated by the transmission groove, and then an entry and exit direction movement having a component in the entry and exit direction is regulated by the regulating groove, so that the binding part comes into contact with the bundle of recording materials.

11 . A binding apparatus comprising:
a set of pressing parts configured to press and bind a bundle of recording materials from one side and a remaining side in a thickness direction; and a cleaning part configured to slide relative to the pressing part and clean at least one pressing part among the set of pressing parts when the pressing part moves along a predetermined binding path.

12 . The binding apparatus according to claim 11 , wherein
the movement of the pressing part along the binding path has a component of a pressing direction movement in a direction where the bundle of recording materials is pressed and a component of an entry and exit direction movement in a direction where the recording material or the bundle of recording materials enters and exits with respect to a pressing region in which the bundle of recording materials is pressed, and in the sliding, the component of the entry and exit direction movement of the pressing part is greater than the component of the pressing direction movement.

13 . The binding apparatus according to claim 11 , further comprising a mounting member on which the cleaning part is provided, wherein
the mounting member serves as a sheet pushing member that pushes the bundle of recording materials before the bundle of recording materials is pressed by the pressing parts.

14 . The binding apparatus according to claim 11 , wherein
each pressing part has a tooth form for binding the bundle of recording materials, and the tooth form of the pressing part has teeth extending in parallel with an entry and exit direction where the recording material or the bundle of recording materials enters and exits.

15 . The binding apparatus according to claim 11 , wherein each pressing part has a tooth form for binding the bundle of recording materials, and the cleaning part is formed so as to engage with the tooth form according to a shape of teeth of the tooth form.

16 . The binding apparatus according to claim 11 , further comprising:
a case configured to support the set of pressing parts; a moving mechanism movably mounted to the case by means of a moving mounting part; and a connecting mechanism movably mounted to the case by means of a connecting mounting part at a position different from that of the moving mounting part.

17 . A binding apparatus comprising:
a set of pressing parts configured to be movable from a retreat position to a binding position and to press and bind a bundle of recording materials at the binding position; and a cleaning part provided to clean at least one pressing part among the set of pressing parts and configured to move, together with the pressing part, toward the binding position as the pressing part moves toward the binding position and to move, together with the pressing part, toward the retreat position as the pressing part moves toward the retreat position.

18 . The binding apparatus according to claim 17 , wherein
the cleaning part is movably mounted to the pressing part by means of a mounting mechanism, and moves together with the pressing part as the pressing part moves.
