DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable printer which can be used for either roll paper such as label paper or continuous paper.

[0002]

2. Description of the Related Art A conventional portable printer will be described below.

As shown in FIG. 15, a conventional portable printer comprises a main body 1 and a lid 2 provided on the main body 1 so as to be openable and closable. The main body 1 has a roll paper 16.
Storage room 4 was provided. The cover 2 is provided with a thermal head 5 for printing roll paper 16, and a platen 6 is provided on the main body 1 side facing the thermal head 5.
Was provided. A roller 7 is used for feeding roll paper. Reference numeral 8 denotes a first discharge port provided on an extension of the lead-out path 9 of the roll paper 16,
Release paper 29 (not shown) from label paper 28 (not shown)
Is an outlet for the separated label 30 (not shown).
Reference numeral 10 denotes a second outlet, which is formed between the tip of the lid 2 and the main body 1. Release paper 29 or continuous paper 34 (not shown) from which the label 30 of the label paper 28 is separated is discharged from the second discharge port 10.

The operation of the portable printer constructed as described above will be described below. There are two types of roll paper 16 stored in the storage room 4, a label paper 28 on which a label 30 is attached and a continuous paper 34 that is continuously printed. When the label paper 28 is loaded, the label 3
The label paper 28 with the label “0” is put in the storage room 4, the label paper 28 is attached to the second discharge port 10 side along the lead-out path 9, and the lid 2 is closed. Then, printing is performed in this state.
Since the label 30 is hard, the label 30 is discharged from the first discharge port 8 on the extension of the lead-out path 9, and the release paper 29 to which the label 30 has been attached is discharged from the second discharge port 10.

On the other hand, when the continuous paper 34 is loaded, the leading end of the continuous paper 34 is passed through the first discharge port 8 to close the lid 2. That is, in the case of the label paper 28, the setting is made through the second discharge port 10, whereas in the case of the continuous paper 34, the setting is made through the first discharge port 8. Thus, the setting method is different depending on the roll paper 16.

As a similar technique, there is, for example, Japanese Patent Application Laid-Open No. Hei 8-295323.

[0007]

However, in such a conventional configuration, of the two types of roll paper 16, the label paper 28 is set to the second discharge port 10, and the continuous paper 34 is set to the second discharge port 10. Through the first outlet 8,
Different outlets have to be set for different roll papers 16, and the operation is very troublesome.

The present invention has been made to solve the above problems, and has as its object to provide a portable printer with good operability.

[0009]

In order to achieve this object, a portable printer according to the present invention is provided with a detachable body rotatable around a rotation axis of a platen, and a first part provided on a lid portion along an extension of a lead-out path. And a second outlet is formed between the tip of the lid and the main body by closing the lid.

As a result, operability can be improved.

In the first embodiment, the inner-wrapped label paper 51 is used. In the apparatus according to the first embodiment, when the outer-wrapped label paper 52 is used, when the label paper 52 is guided from the storage chamber 15 to the lead-out path 19, the label paper 52 is not smoothly led out at the connection part on the way. In other words, it sometimes jammed. Embodiment 2 improves the jamming.

FIG. 10 is a sectional view of a portable printer according to the second embodiment. In FIG. 10, reference numeral 11 denotes a main body, and 53 denotes a lid rotatably provided on the main body 11. The cover 53 is provided with a roll paper guide 54 that forms the storage chamber 15. The roll paper guide 54 has a semicircular shape, and one end 54a of the roll paper guide 54 and the connecting portion 55 of the lead-out path 19 are formed as curved surfaces. It is desirable that the radius 56 of the curved surface be larger than the radius of the inner diameter of the paper tube 50 of the label paper 52 or the roll paper. As a result, the roll paper 52
It can be smoothly led out to the lead-out path 19 without jamming.

FIG. 11 shows the relationship between the label paper 52 and the connection part 55. Here, the connecting portion 55 is provided with a rib 57. The rib 57 is provided corresponding to the inside of the width of the label paper 52. As a result, even if the adhesive pasting the label 30 on the label paper 52 protrudes when pressed, the glue adheres to the connection portion 55, and the label paper 52 is smoothly led out without jamming on the rib 57. You.

FIG. 12 shows six ribs 58 on the connecting portion 55.
This is an example in which is provided. In this manner, the rib 58 is provided on the connecting portion 55.
Is provided, even if the paper width of the label paper 52 changes. That is, it can correspond to label paper having various paper widths.

FIG. 13 is a plan view of the connecting portion 55. FIG. In this, a plurality of ribs 58 are arranged in parallel to the direction in which the label paper is led out. This allows the label paper 52 to be drawn out in parallel to the drawing direction. Label paper 5
The frictional resistance between the rib 2 and the rib 58 can be reduced. Therefore, the label paper can be smoothly derived.

FIG. 14 shows the cross-sectional shape of the rib 58. FIG. 14A shows a top surface of the rib 58 formed in a circular shape. This results in lower frictional resistance.
FIG. 14 (b) has a flat top surface and rounded ends. FIG. 14C shows the top surface formed at an acute angle.
