Claims
- 1. A tape processing device for processing a peel-off paper-backed adhesive tape,said tape processing device comprising: a trimming mechanism for trimming an end of said peel-off paper-backed adhesive tape; a peeling mechanism for peeling off a peel-off paper from said peel-off paper-backed adhesive tape; single driving means for driving said trimming mechanism and said peeling mechanism; and driving force-transmitting means for transmitting driving force from said driving means to said trimming mechanism and said peeling mechanism; said peeling mechanism peeling off the peel-off paper through rotation into contact with a free portion of an end of said adhesive tape, to thereby carry out a bending and releasing action on said free portion of said end of said adhesive tape.
- 2. A tape processing device for processing a peel-off paper-backed adhesive tape,said tape processing device comprising: a trimming mechanism for trimming an end of said peel-off paper-backed adhesive tape; a peeling mechanism for peeling off a peel-off paper from said peel-off paper-backed adhesive tape; single driving means for driving said trimming mechanism and said peeling mechanism; and driving force-transmitting means for transmitting driving force from said driving means to said trimming mechanism and said peeling mechanism; said driving means including a drive shaft and a motor for rotating said drive shaft, said driving force-transmitting means having a one-way clutch having an input-side thereof fixed to said drive shaft and an output-side thereof connected to said trimming mechanism to thereby transmit only torque in a normal direction to said trimming mechanism.
- 3. A tape processing device according to claim 2, wherein said one-way clutch comprises a first gear fixed to said drive shaft, a second gear mated with said first gear, an output wheel arranged coaxially with said second gear with an output-side thereof being connected to said trimming mechanism, and a clutch body interposed between said second gear and said output wheel to transmit only said torque in said normal direction from said motor to said trimming mechanism.
- 4. A tape processing device according to claim 3, wherein said clutch body has a ratchet wheel arranged on one of said second gear and said output wheel, a ratchet pawl pivotally arranged on another of said second gear and said output wheel for being mated with said ratchet wheel, and a spring urging said ratchet pawl in a mating direction.
- 5. A tape processing device according to claim 3, wherein said trimming mechanism includes a crank mechanism for converting rotation of said output wheel into reciprocation, and a cutter actuated by said reciprocation of said crank mechanism, for a cutting operation.
- 6. A tape processing device according to claim 3, wherein said first gear further includes an output block for transmitting both said torque in said normal direction and torque in a reverse direction from said motor to said peeling mechanism.
- 7. A tape processing device according to claim 2, wherein said one-way clutch comprises an input-side face ratchet fixed to said drive shaft and an output-side face ratchet rotatably and axially slidably supported on said drive shaft.
- 8. A tape processing device according to claim 7, wherein said output-side face ratchet has a worm on an output-side thereof, said trimming mechanism having a worm wheel mated with said worm on an input-side thereof, andwherein a viscous material is filled between said drive shaft and said worm, for causing said worm to rotate in a free-running manner with rotation of said drive shaft.
- 9. A tape processing device according to claim 8, further including a stopper for limiting movement of said worm in an axial direction in a manner such that said worm is mated with said worm wheel in a state in which said input-side face ratchet and said output-side face ratchet are disengaged from each other.
- 10. A tape processing device according to claim 8, wherein said trimming mechanism includes a crank mechanism for converting rotation of said worm wheel into reciprocation, and a cutter actuated by said reciprocation of said crack mechanism, for a cutting operation.
- 11. A tape processing device according to claim 7, wherein said input-side face ratchet further includes an output block for transmitting both said torque in said normal direction and torque in a reverse direction from said motor to said peeling mechanism.
- 12. A tape processing device for processing a peel-off paper-backed adhesive tape,said tape processing device comprising: a trimming mechanism for trimming an end of said peel-off paper-backed adhesive tape; a peeling mechanism for peeling off a peel-off paper from said peel-off paper-backed adhesive tape; single driving means for driving said trimming mechanism and said peeling mechanism; driving force-transmitting means for transmitting driving force from said driving means to said trimming mechanism and said peeling mechanism; and a device casing formed with a trimming guide slit for guiding said peel-off paper-backed adhesive tape inserted therein to said trimming mechanism and a peeling guide slit for guiding said peel-off paper-backed adhesive tape inserted therein to said peeling mechanism, said trimming guide slit and said peeling guide slit being arranged adjacent to each other.
- 13. A tape processing device according to claim 12, wherein said trimming guide slit and said peeling guide slit are different in direction of inserting said peel-off paper-backed adhesive tape.
- 14. A tape processing device according to claim 12, further including normal rotation control means for detecting said peel-off paper-backed adhesive tape inserted into said trimming guide slit to thereby cause said motor to rotate in a normal direction.
- 15. A tape processing device according to claim 12, further including inverse rotation control means for detecting said peel-off paper-backed adhesive tape inserted into said peeling guide slit to thereby cause said motor to rotate in a reverse direction.
- 16. A tape printing apparatus which is capable of using a peel-off paper-backed adhesive tape,said tape printing apparatus comprising: printing means for printing said peel-off paper-backed adhesive tape; cutter means for cutting off said peel-off paper-backed adhesive tape to a predetermined length; tape-feeding means for bringing said peel-off paper-backed adhesive tape printed by said printing means to said cutter means and sending said peel-off paper-backed adhesive tape out of said tape printing apparatus; and a tape processing device for processing said peel-off paper-backed adhesive tape cut to said predetermined length, said tape processing device including: a trimming mechanism for trimming an end of said peel-off paper-backed adhesive tape cut to said predetermined length, a peeling mechanism for peeling off a peel-off paper from said peel-off paper-backed adhesive tape cut to said predetermined length, single driving means for driving said trimming mechanism and said peeling mechanism, and driving force-transmitting means for transmitting driving force from said driving means to said trimming mechanism and said peeling mechanism; said peeling mechanism peeling off the peel-off paper through rotation into contact with a free portion of an end of said adhesive tape, to thereby carry out a bending and releasing action on said free portion of said end of said adhesive tape.
