[0002]

2. Description of the Related Art In a conventional hand labeler or the like,
For example, an endless band for printing formed with printing characters and heading characters is rotatably supported on a selection wheel or the like, and by rotating this, a desired printing character can be printed, and ink is applied to the printing characters by an ink roller or the like. It is applied and stamped on labels and the like. In this printing selection, the endless band for printing is selected (indexed) by moving the operation axis for printing selection in the direction of the axis, and the selection wheel is set by rotating the operation axis in this line. (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, the moderation of the printing selection is obtained by the elastic deformation of the elastic engaging piece or the flexible piece in the positioning member fixed at a predetermined position, so that the positioning accompanying the printing selection operation is performed. There is a problem of wear and durability due to repeated engagement and disengagement between the member and the selection wheel.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems. In order to obtain moderation in printing selection, the present invention provides a printing device having excellent durability by suppressing abrasion as much as possible. It is an object to provide a selection device.

The movable stopper member can be moved by engaging and disengaging the outer peripheral engagement groove of the selection wheel and the moderation boss portion of the movable stopper member with rotation of the selection wheel in a print selection operation. It is a print selection device in a printing device.

By providing a stopper guide for guiding the movable stopper member in its movable direction, the movable action of the movable stopper member can be stabilized.

Since the elastic portion has a bifurcated locking spring portion, the bifurcated locking spring portion can be elastically deformed in the horizontal direction, for example, when the movable stopper member is used for up and down operation. Since the movement of the stopper member can be made smooth and the necessary elastic portion can be arbitrarily large, the degree of freedom in the design can be increased.

The stopper receiving member has a receiving portion inclined surface for receiving the elastic portion, so that when the movable stopper member moves, the elastic portion is elastically deformed along the receiving portion inclined surface, and The elastic movement can be performed smoothly.

In the printing selection device of the printing device according to the present invention, the moderation boss portion and the elastic portion are formed on the movable stopper member. When the selection wheel is rotated, the moderation boss portion is disengaged from the selection wheel and the elastic portion is moved. By the elastic deformation, a moderation in the print selection operation can be obtained.

Therefore, by rotating the selection wheel and rotating the endless band for printing around it, it is possible to arbitrarily select the printing characters or heading characters of the endless band for printing.

When the elastic portion is elastically deformed,
The entire movable stopper member moves (in a direction away from the selection wheel), and the moderation boss portion, which is a portion engaged and disengaged from the selection wheel, is less likely to be worn. That is,
The part where the movable stopper member engages with the selection wheel is
This is a modest boss that is hardly deformed, and the elastic portion that allows this engagement and disengagement is provided on the print receiving table side opposite to the selection wheel. Can be suppressed, and the degree of freedom in designing the elastic portion can be increased.
