Such a roll paper feeding device 2 acts as an eye movement when the handle 5 for printing is rotated back and forth, in other words, it is swung, and the handle 5 is moved forward from the state shown in the figure. When it is swung to
-ru link 8, 8 (thus che7 or []-zo39
(hereinafter simply referred to as che 739)) is pulled, and the sliding piece 29 slides rearward against the biasing force of a spring (not shown).

1j) When the moving piece 29 retreats, the feed blade 3 on its lower surface
2 slides on the upper surface of the base 1 and retreats, leaving the supplied paper P' set on the base 1 in that position.

On the other hand, printing that rolls forward [1-ra 9 is the supply paper p
Among the labels or tags (hereinafter simply referred to as labels) attached at appropriate intervals to a continuous backing paper, those that are in the printing position are printed via the printing cart stored in the cart holder 17. give

At this point, if the handle 5 is not returned to its original position, the tension spring 40 will first contract, and then the spring provided near the sliding piece 29 will begin to contract, and the sliding piece 29 will continue to pull back the check 739. It slides in the guide frame 28, returns to the front side, and stops.

When the sliding piece 29 starts moving forward from the rear position, the feeding blade 32 bites into the rear side of the label immediately after the printed label, and sends the entire sheet P' forward.

As the paper P' advances, the amount of paper that has been fed is unwound from the roll paper P, and the printed label is sent to the outside of the machine, and the subsequent label is sent to the printing position.

By repeating this operation, the paper P' is automatically fed out from the roll P, and the unit labels are printed one after another.

Next, the printing stroke switching device, which is the essential part of this invention, can be used in the above-mentioned printing machines, and the above-mentioned manual address printing machine is an example of a printing machine in which it is implemented.

For example, the printing paper is limited to one that is continuously fed from the support frame 22, and may be of a type in which each paper is sandwiched from the front (note that the printing machine shown in the drawing is in a roll form). It can be used for either paper or single sheet paper.
