Abstract

A binding mechanism has a base, a feeder, a tape cutting unit, a tape holding unit and a tape support driving unit. The feeder is supported by the base. The feeder feeds an adhesive tape. The tape cutting unit is supported by the base. The tape cutting unit cuts the fed adhesive tape. The tape holding unit can hold the fed adhesive tape. The tape support units are installed as a pair. The tape support driving unit drives the pair of tape support units such that the pair of tape support units hold the fed adhesive tape simultaneously.

First claim

What is claimed is:

1. A binding mechanism comprising:
a base;
a feeder supported by the base and to feed an adhesive tape;
a tape cutting unit supported by the base and to cut the fed adhesive tape;
a tape adhesion unit to attach the cut adhesive tape to a paper bundle;
a pair of tape support units to hold the fed adhesive tape; and
a tape support driving unit to drive the pair of tape support units such that the pair of tape support units hold the fed adhesive tape simultaneously, wherein
the tape adhesion unit includes a pair of rollers that face each other.

2. The binding mechanism according to claim 1 ,
wherein the tape support driving unit drives the pair of tape support units such that the tape cutting unit is able to cut the adhesive tape between holding sections of the adhesive tape when the adhesive tape is pressed by the pair of tape support units.

3. The binding mechanism according to claim 1 ,
wherein each of the tape support units includes a pair of holding plates that are separated from each other such that a member to be bound is insertable between the holding plates.

4. The binding mechanism according to claim 1 ,
wherein the feeder, the tape cutting unit and the tape support driving unit comprise operation input shafts disposed on the same axis.

5. The binding mechanism according to claim 1 ,
wherein the tape support driving unit is able to move the pair of tape support units in a direction parallel to a feeding direction of the adhesive tape fed by the feeder.

6. The binding mechanism according to claim 1 , further comprising
an interlocking switching mechanism to switch between a state in which the feeder and the tape cutting unit are interlocked and a state in which the feeder and the tape cutting unit are not interlocked.

7. The binding mechanism according to claim 1 ,
wherein the tape support driving unit comprises:
a first driving mechanism to drive the pair of tape support units in a direction perpendicular to a feeding direction of the adhesive tape fed by the feeder; and
a second driving mechanism to drive the pair of tape support units in a direction parallel to the feeding direction of the adhesive tape fed by the feeder.

8. The binding mechanism according to claim 7 , further comprising:
a first operation input unit to input an operation to the first driving mechanism; and
a second operation input unit to input an operation to the second driving mechanism.

9. The binding mechanism according to claim 1 ,
wherein the tape cutting unit comprises a cutting force transmission mechanism to perform a storing operation of storing a cutting force in a direction opposite to a cutting direction of the adhesive tape and a cutting operation of applying the cutting force in the cutting direction of the adhesive tape.

10. The binding mechanism according to claim 9 ,
wherein the cutting force transmission mechanism comprises two springs having different spring constants.

11. The binding mechanism according to claim 1 ,
wherein the tape support driving unit alternately drives the pair of tape support units in a direction perpendicular to a feeding direction of the fed adhesive tape by the feeder such that the pair of tape support units pass each other in a direction parallel to the feeding direction of the adhesive tape fed by the feeder alternately.

12. The binding mechanism according to claim 1 , further comprising
a cover guide to have both a cover function of the tape cutting unit and a guide function of a member to be bound.

13. The binding mechanism according to claim 1 , further comprising
a curve guide to bend an insertion path of a member to be bound.

14. A binding mechanism comprising:
a grip;
a lever biased in a direction away from the grip and movable in a direction of approach to the grip;
a base fixed to the grip;
a feeder supported by the base and interlocked with the lever to feed an adhesive tape;
a tape cutting unit supported by the base and to cut the fed adhesive tape in conjunction with the lever;
a tape adhesion unit to attach the cut adhesive tape to a paper bundle;
a tape holding unit to hold the fed adhesive tape; and
a tape support driving unit interlocked with the lever to drive the tape holding unit, and to hold the fed adhesive tape using the tape holding unit and provide the adhesive tape to the tape adhesion unit, wherein
the tape adhesion unit includes a pair of rollers that face each other.

15. A binding unit comprising:
a base;
a feeder supported by the base and to feed an adhesive tape;
a tape cutting unit supported by the base and to cut the fed adhesive tape;
a tape adhesion unit to attach the cut adhesive tape to a paper bundle;
a pair of tape support units to hold the fed adhesive tape;
a tape support driving unit to drive the pair of tape support units such that the pair of tape support units hold the fed adhesive tape simultaneously; and
a driving motor to drive the feeder, the tape cutting unit and the tape support driving unit, wherein
the tape adhesion unit includes a pair of rollers that face each other.
