Description

[Detailed Description of the Invention] This invention relates to a label pressing device for a label printer.

This type of device is equipped with at least a printing section, a peeling plate that bends the backing paper at an acute angle, and a feed section that sends out the backing paper, in the path of a long backing paper on which a large number of labels are pasted. In order to peel off the mount from the mount, tension must be applied to the mount.

Conventionally, as shown in FIG. 1, a mount sheet wound around a label supply section a is pulled out toward a printing section, and a guide surface C and a support fitting d are provided facing each other in the path thereof, and this support A label pressing device is used in which a shaft f for holding a presser plate e is held in a slidable manner by a spring g while being biased in the pressing direction by a metal fitting d.

However, in addition to the spring g, such a support metal fitting d
This requires a holding plate e and a shaft f, which increases the number of parts.

Furthermore, the number of assembly steps also increases. In addition, when inserting the backing paper between the presser plate e and the guide surface C, a stopper h is provided on the shaft f, and two large and small holes 1. form j,
This method involves placing a stopper h protruding from a large hole i above a small hole j to keep the presser plate e floating, but this method also has the disadvantage of increasing the number of parts. .

The object of this invention is to provide a label pressing device for a label printer that can eliminate the above-mentioned drawbacks.

An embodiment of this invention will be explained based on FIGS. 3 to 6.

1 is the main case of the label printer, this main case 1
A door 3 equipped with a label issuing port 2 is provided on the front surface of the door 3 so as to be openable and closable, and an opening 4 is formed on the top surface.

A frame 6 whose front surface serves as a guide surface 5 is provided inside the main body case 1, and a long mount 8 on which a plurality of labels 7 are pasted is wound around the top surface of the frame 6 in the form of a roll. The holding label supply section 9 is fixed.

This mount 8 is pulled out into the main body case 1, and the printed part, the product name printed part, and the mount 8 are bent at an acute angle, and the label 7 is peeled off from the mount 8, and the label issuing port 2 is opened. A peeling plate, a feeding section, and a mount winding section, which are led out to each other, are provided in the main body case 1, although they are not shown.

On both sides of the guide surface 5, openings 10 having the shape of an inverted "concave" are formed as shown in FIG.
The edge of the protrusion 11 that becomes a part of the opening edge is a locking edge 12.

A locking hole 13 for locking one end of a spring, which will be described later, is formed in the lower part of the opening 10.

A pressing body 14 is then provided.

This pressing body 14 is integrally formed by press working, resin molding, or casting, and has a base 1 having an angular cross section.
A guide part 16 having an angled cross-section is formed on one edge of the label supply part 9 side of the label supply part 5, a presser part 17 is formed on the other edge, and an insertion part 18 to be inserted into the opening 10 is formed on both sides. A notch 19 is formed at the lower edge of the insertion portion 18, and a stopper 21 is formed on the outside to abut the upper edge 20 of the opening 10.

Furthermore, a lever 22 is integrally formed on one of the insertion portions 18 .

Thus, while inserting the insertion portion 18 into the opening 10, the notch 19 is engaged with the locking edge 12, and one end of the tension spring 23, which is a spring, is locked in the locking hole 13. By locking the end to the stopper 21, the pressing body 14 is rotatably held on the guide surface 5.

The end of the tension spring 23 on the side that is locked by the pressing body 14 is set at a position where the insertion portion 18 enters and projects into the opening 10 by the rotation of the pressing body 14.

In such a configuration, in FIGS. 5 and 6,
When the lever 22 is operated, the pressing body 14 rotates about the notch 19 as a fulcrum.

FIG. 5 shows that the locking point of the tension bar i/w 23 with the pressing body 14 is located inside the opening 10, and as a result, the pressing body 14 is urged clockwise and the pressing part 17 is forced against the force 41 and the pressing body 5. float.

In this state, since the stopper 21 engages with the upper edge 20 of the opening 10, there is also a gap between the guide portion 16 and the guide surface 5.

Therefore, the mount 8 set in the label supply section 9 can be easily introduced onto the front surface of the guide surface 5 while being guided by the guide section 16.

In this state, the lever 22 may be turned counterclockwise, but
When the mount 8 is pulled downward to apply tension, the tension acts on the guide surface 16, and as a result, the pressing body 14 rotates counterclockwise about the notch 19 as a fulcrum as shown in FIG. 6, and the tension spring 23 Since the locking point with the pressing body 14 is located outside the opening 10, the tension spring 23 urges the pressing body 14 in a counterclockwise direction.

Therefore, the presser portion 17 presses the mount 8 against the guide surface 5.

That is, the tension spring 23 functions as a toggle spring, urging the pressing body 14 in a direction to lift the presser part 17 from the guide surface 5 when setting the mount 8, and when reversing the pressing body 14. urges the pressing body 14 in the direction of pressing the presser portion 17 or the paper 8.

Furthermore, when setting the mount 8, a guide section 16 is provided, and the pressing body 14 can be reversed simply by applying the tension of the mount 8 to the guide section 16, making it extremely easy to set the mount 8. You can make it happen.

Since the pressing body 14 is held by the guide surface 5, there is no need for a separate support member, and the number of parts can be significantly reduced and assembly can be simplified.

Since this device is constructed as described above, by rotating the pressing body using the notch as a fulcrum, the spring can be attached in two states: one in which the presser part is floating above the guide surface, and the other in which it is pressed against the guide surface. The presser surface can be lifted from the guide surface to facilitate insertion of the mount, and the mount can be pressed by rotating the pressing body in the opposite direction. Since it is held, there is no need for a separate support member, which reduces the number of parts and facilitates assembly.
