The drop-off prevention member 210 urged by the urging member 220 and rotated to the drop-off prevention position comes into contact with a pin 215b provided protruding from the label holding shaft 215, and its position is determined. With the above configuration, the urging member 220 urges the dropout prevention member 210 toward the dropout prevention position.

  In order to move the dropout prevention member 210 to the release position shown in FIG. 9, the user places the dropout prevention member 210 in the direction of arrow Q in FIG. 8 or a hole provided in the center of the label 3 without mount. It is necessary to press it with the wall surface. However, this operation is a very simple operation and does not become complicated when the mountless label 3 is attached or removed. On the other hand, once the mountless label 3 is correctly attached to the paper holder 204, the dropout prevention member 210 is always in the dropout prevention position by the biasing force of the biasing member 220 as shown in FIG. Therefore, it is possible to reliably prevent the non-mounting label 3 from dropping from the paper holder 4.

  As described above, according to the second embodiment, the drop-off prevention member 210 is provided so as to be rotatable, and the drop-off prevention member 210 is urged toward the drop-off prevention position by the urging member 220. Therefore, the drop-off prevention member 210 can prevent the label 3 without the mount from dropping out of the paper holder even if the posture of the label applicator changes or the label applicator is handled roughly. Further, since the drop-off prevention member 210 can be easily moved to the release position by being pushed by hand or the like, the loading operation of the non-mounting label 3 can be easily performed.
