Abstract

PURPOSE:To make the exchange of printing tapes easier without interrupting the maintenance of a printer by miniaturizing a tape unit (cassette) having a system in which the tape is pulled out only by a necessary length during the printing operation and the tape is housed when printing is ended. CONSTITUTION:The tape outlet 1c and tape inlet 1d of a tape unit (cassette) 1 are provided near the end portion on printing starting side of the reciprocal movement track in a printing head 6. When a printing tape T reaches the head 6 along the track of the head 6 from the outlet 1c and a reverse turning- preventing roller 7 provided to the head 6 is turned and passed through a printing section 6a, the tape T is again returned to the inlet 1d along the track of the head 6.

Conventionally, in this type of mechanism, the printing tape is always pulled out in the area of the print head's track by the length required for recording or more, and when printing, the print head moves against the printing tape. A configuration is known in which printing is performed by running along a portion of the print head drawn out into the track area of the print head, but in this configuration, the printing tape covers the entire width of the recording paper or Because it is constantly being pulled out for longer than that, the printing tape supply reel, I4A
The tape unit 7 that must accommodate the reel becomes large, which impedes maintenance of the main body of the recorder, printer, etc. to which this tape unit is installed, and when replacing the printing tape, it is difficult to pull out the printing tape. Replacement work was troublesome because the exposed parts were long.

1-Efficiency In view of the above points, the present invention makes the tape unit smaller by pulling out the printing tape by the required length during printing and storing the printing tape after printing is completed. It is an object of the present invention to provide a guide mechanism for a printing tape that does not interfere with maintenance of the main body and is easy to replace.

This purpose is to provide a printing tape supply reel that can be rotated in one direction via a slip mechanism, and a printing tape supply reel that can be rotated in the same direction as the supply reel via a reversal prevention mechanism. The printing tape is guided from the supply reel and the take-up reel via a take-up reel and a guide member to a tape outlet and a tape inlet, which are disposed near the ends of the reciprocating trajectory of the print head on the printing start side. and a tape unit removably attached to the main body, the printing tape being guided from the supply reel along the guide path from the tape outlet along the trajectory of the print head. The tape reaches the print head, winds a reversal prevention roller provided on the print head, uses the printing section, returns along the trajectory of the print head, and is rotated from the inlet to the take-up reel along the guide path,
When 7 moves in the printing direction, the printing tape is pulled out only from the supply reel and printing is performed, and when the print head moves in the return direction, the printing tape moves toward the printing part of the print head. This problem is solved by a guide mechanism for the printing tape, which is characterized in that the printing tape is wound onto the supply reel and the take-up reel by driving the supply reel and the take-up reel without moving relative thereto.

Since the embodiment of the present invention is configured as described above, when the print head 6 moves from the print start position in the printing direction as shown by the arrow A, the take-up reel 3 has a reverse rotation prevention mechanism with respect to the pulley 3a. Since reverse rotation is prevented by the movement of the print head 6, the supply reel 2 rotates counterclockwise by the action of the slip mechanism, and the printing tape T is fed out, and thus the portion of the printing tape T that comes into contact with the printing part 6a of the print head 6 is stationary with respect to the main body and tape unit 1, and printing is performed as the print head 6 moves.When the print head 6 reaches the printing end position, the above operation stops, and then the print head 6 moves as indicated by arrow B. When moving in the return direction as shown, the drive shaft 4 rotates and the supply reel 2 and take-up reel 3
is rotated clockwise, and at this time, the printing tape T is prevented from moving backwards over the printing section 6a of the printing head 6 by the anti-reverse rollerf; The used part is then taken up by the take-up reel 3 and the unused part by the supply reel 3 without any movement.

By repeating the above operations, printing is performed sequentially, and the printing tape T is fed and used by the length required for printing, and the used printing tape T is wound onto the take-up reel 3 and printed. When the winding diameter of the tape T becomes larger than the predetermined amount,
When the microswitch 8 is activated, an appropriate device (not shown) notifies the operator that the printing tape T should be replaced.

As described above, according to the present invention, the tape outlet of the tape unit and the tape base are placed near the end of the reciprocating trajectory of the print head on the printing start side, and the printing tape is moved from the tape outlet. The print head is configured to reach the print head along the path of the print head, wind the anti-reverse roller provided on the print head, pass through the print section, and return to the cough tape entrance again along the trajectory of the print head. When the print head moves in the printing direction, the print tape is pulled out from the supply reel only and printing is performed, and when the print head moves in the return direction, the print tape is pulled out onto the printing part of the print head. Since the printing tape is wound onto the supply reel and take-up reel by driving the supply reel and take-up reel without moving, the printing tape is pulled out by the required length during printing, and after printing is completed, the printing tape is pulled out. Since the printing tape is drawn into the tape unit by winding the unused portion onto the supply reel and the used portion onto the take-up reel, the tape unit can be constructed in a compact size, and maintenance of the main body can be done by the tape unit itself. It is extremely effective as it is not obstructed by the printing tape that is pulled out and is easy to replace.
