Abstract

A stapler apparatus includes a staple driving member to drive staples into a sheet bundle and being reciprocally supported on a frame. The staple driving member is configured to engage and drive staples. A cam member is interlocked to the staple driving member to reciprocally move the staple driving member. A drive motor is interlocked to the cam member. The cam member includes at least two rotating cams comprising rotating shafts extending in a direction intersecting a plane formed by said staple driving member reciprocal movement locus. The two rotating cams and the staple driving member abut at at least two points.

Claims (13)

1. A stapler apparatus comprising a staple driving member to drive staples into a sheet bundle and being reciprocally supported on a frame, the staple driving member configured to engage and drive staples, a cam member interlocked to said staple driving member to reciprocally move said staple driving member and a drive motor interlocked to said cam member, said cam member comprising:

at least two rotating cams comprising rotating shafts extending in a direction intersecting a plane formed by said staple driving member reciprocal movement locus, said two rotating cams and said staple driving member abutting at at least two points.

2. Said stapler according to claim 1 , wherein said rotating shafts of said rotating cams are arranged to virtually cross said plane formed of said reciprocal movement locus of said staple driving member.

3. Said stapler apparatus according to claim 1 , wherein said rotating cams have cam faces displaced in a direction of reciprocal movement of said staple driving member as said rotating cams rotate.

4. Said stapler apparatus according to claim 1 , wherein at least said two rotating arms are linked to said drive motor so that said rotating cams rotate in different directions.

5. Said stapler apparatus according to claim 1 , wherein said staple driving member is engaged with at least said two rotating cams to transmit forward and backward movements to said staple driving member.

6. Said stapler apparatus according to claim 5 , wherein said staple driving member and said rotating cams have pin members formed on either one and slit grooves formed on said other one, said pin members and slit grooves being fitted together to engage.

7. A stapler apparatus comprising a plate-shaped staple driving member to drive staples into a sheet bundle and being reciprocally supported between left and right paired side frames, the staple driving member configured to engage and drive staples, a cam member interlocked to said staple driving member to reciprocally move said staple driving member supported between said paired side frames and a drive motor interlocked to said cam member, wherein said cam member comprises at least two rotating cams each including a respective rotating shaft, the rotating shafts thereof extending in a direction intersecting a plane formed by the locus of reciprocal movement of said staple driving member, wherein said two rotating cams and said staple driving member abut at at least two points.

8. Said stapler according to claim 7 , wherein said rotating shafts of said rotating cams are arranged to virtually cross said plane formed of said reciprocal movement locus of said staple driving member.

9. Said stapler apparatus according to claim 7 , wherein said rotating cams have cam faces displaced in a direction of reciprocal movement of said staple driving member as said rotating cams rotate.

10. Said stapler apparatus according to claim 7 , wherein at least said two rotating cams are linked to said drive motor so that said rotating cams rotate in different directions.

11. Said stapler apparatus according to claim 7 , wherein said staple driving member is engaged with at least said two rotating cams to transmit forward and backward movements to said staple driving member.

12. Said stapler apparatus according to claim 11 , wherein said staple driving member and said rotating cams have pin members formed on either one and slit grooves formed on said other one, said pin members and slit grooves being fitted together to engage.
