DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a print selection device in a printing device, and more particularly to a print selection device in a two-line printing device mounted on a portable label printing and pasting device (handler labeler).

[0002]

2. Description of the Related Art In a conventional hand labeler or the like,
An endless band for printing, for example, on which a printing character and a heading character are formed, is rotatably supported on a selection wheel or the like, and is rotated so that a desired printing character can be printed, and ink is applied to the printing character by an ink roller or the like. And stamp it on a label or the like. In this printing selection, a row of printing endless bands is selected (indexed) by moving an operation axis for printing selection in the direction of the axis, and a selection wheel is set by rotating the operation axis in this row. (A proper set state of each print character or a distinction between the set states) to select a desired print character in the endless band for printing.

[0003] Such a print selection device has various mechanisms for the above-mentioned indexing and moderation. For example, Japanese Utility Model Publication No. 55-38681 uses a support positioning member integrally formed with an elastic engagement piece. In addition, 5
In Japanese Patent Application No. 8-218861, a positioning member integrally formed with a flexible piece and a positioning piece biased by a spring are used.

However, in any case, since a moderation is made at a portion such as a selection wheel at a portion remote from the operation axis, a so-called solid response is felt as a feeling when the operator touches a finger when printing is selected. There was a problem with the operational feeling, not one. In addition, since the indexing mechanism and the moderation securing mechanism are located in separate areas, there is a sense of incongruity due to the difference in the operational sensations of each, and collective confirmation during assembly or maintenance and inspection. There is a problem that it is difficult to do. Since the elastic force of the positioning member itself is used, there is a problem that there is a difficulty in designing the urging force.
