Device for attaching leader pin, device for processing end portion of tape type recording medium, and method for attaching leader pin
View Patent ↗A leader pin attaching device for attaching a leader pin to a pin attachment portion of the leader tape (a device for processing end portion of tape type recording medium) is provided. The device includes a transport suction block for holding a portion of the leader tape by negative pressure with the pin attachment portion of the leader tape being protruded; a clamper mechanical part for engaging the leader pin and a leader pin clip with the pin attachment portion of the leader tape being sandwiched therebetween. The transport suction block holds the leader tape in such manner that the leader tape is allowed to move in machine direction during the engagement of the leader pin and the leader pin clip with the pin attachment portion sandwiched therebetween. With the use of the device, wrinkle formation is prevented when a leader pin is attached to a tape.
1. A device for attaching a leader pin to a pin attachment portion of a leader tape having a joint end and a free end opposite to the joint end, which joint end is to be joined to a joint end of a tape type recording medium and which pin attachment portion is located in the vicinity of the free end, the device comprising:
a suction mechanical part configured to hold a portion of the leader tape by negative pressure, which portion is located on the joint end side relative to the pin attachment portion;
a clamper mechanical part configured to engage the leader pin and a leader pin clip with the pin attachment portion of the leader tape being sandwiched therebetween, wherein
the suction mechanical part holds the leader tape in such manner that the leader tape is allowed to move in a longitudinal machine direction during the engagement of the leader pin and the leader pin clip with the pin attachment portion of the leader tape being sandwiched therebetween.
2. The device according to claim 1 , wherein the suction mechanical part holds the leader tape with a suction power that generates a predetermined pulling-resistance force when the leader tape is pulled in machine direction.
3. The device according to claim 2 , wherein the predetermined pulling-resistance force is 0.3-1.4 N.
4. The device according to claim 2 , further comprising a suction power control unit that controls the suction power to generate the predetermined pulling-resistance force.
5. The device according to claim 1 , further comprising a leader tape that has a larger elastic coefficient in the machine direction than in a direction transverse thereto.
6. The device according to claim 5 , wherein the leader tape has an elastic coefficient in the transverse direction of 0.95-0.78, taking the elastic coefficient in the machine direction as 1.0.
7. The device according to claim 5 , wherein the leader tape has a surface roughness of 10-60 nm.
8. The device according to claim 5 , wherein the leader tape has a thickness of 5-20 μm.
9. The device according to claim 1 , which further comprises an elastic body configured to support the suction mechanical part elastically and movably in the machine direction of the leader tape,
the elastic body having an elastic coefficient that allows the elastic body to elastically support the suction mechanical part while maintaining a predetermined tensile force generated on the leader tape during the engagement of the leader pin and the leader pin clip with the pin attachment portion of the leader tape being sandwiched therebetween.
10. The device according to claim 9 , wherein the predetermined tensile force is 0.3-1.4 N.
11. The device according to claim 1 , which further comprises a transport mechanism configured to transport the suction mechanical part in the machine direction of the leader tape,
the transport mechanism transporting the suction mechanical part while maintaining a predetermined tensile force generated on the leader tape during the engagement of the leader pin and the leader pin clip with the pin attachment portion of the leader tape being sandwiched therebetween.
12. The device according to claim 11 , wherein the predetermined tensile force is 0.3-1.4 N.
13. The device according to claim 1 , wherein said suction mechanical part imparts to the leader tape a pulling-resistance force that is smaller than a tensile force applied to the leader tape by a pulling force caused by said engagement.
