Abstract

PURPOSE:To prevent the up-down movements of a web which is carried by attaching a web coupling pin to an arm that is oscillated by a rotary means in order to reduce the up-down play of the web coupling pin and also to reduce the change of the coupling pin due to the wear. CONSTITUTION:A tape cartridge 1 is loaded to a file reel hub 2 and a leader block 3 set at the tip of a tape is connected to the coupling pin 4 of a tape sledding. A sledding arm 5 is connected to the pin 4 via a guide groove 8 which is guided smoothly to a guide 7 connected rotatably around a sledding drive shaft 6. Then a guide arm 10 is connected freely rotatably to a drive arm 9 connected tight to the shaft 6 of the sledding mechanism. The arm 5 is controlled to the length of the pin 4 connected to the center of the shaft 6 and at the same time rotated by the combination of a guide pin 11 and a cam groove 12. Thus the block 3 is carried along a reader block route 13.

However, since the arm driven by the rotating means, the arm with the pin guided by the cam, and the arm with the connecting pin connectable to the starting end of the web can be connected with pins in a banter-like manner, Due to dimensional play or play due to wear in the arm connection part, the web connecting pin at the tip of the banter arm is likely to play, especially in the vertical direction (when the web is drawn into the web edge guide that is approximately parallel to the web width while being routed) However, no consideration was given to the possibility that the edges of the web could get caught in the guide and be damaged.

In a magnetic tape device that uses a new cartridge-type tape as a compatible medium, the tape loading structure uses a relatively unique structure except for the interface structure with the tape destination 41J-duplex, and is technically the absolute best. Since there is no such thing, the goal is to improve what is considered to be a weak point in the counter area and adopt a mechanical shape with a different structure. The present invention provides a device for transporting a leading end leader block of a tape wound on a supply reel loaded into a magnetic tape device along a tape threading path from the supply reel to the device machine reel.
- an arm having a groove that engages with a guide rotatably connected to the drive shaft and whose length can be varied relative to the drive shaft;
This arm is rotatably connected to one end and a guide pin attached to the other end is guided by a guide cam.One end is rotatably connected to the middle of the guide arm and the other end is fixed to the drive shaft. The IJ-double block is conveyed over a predetermined path by rotating the arm while expanding and contracting in conjunction with each other.
