2. Description of the Related Art Folded recording paper and roll recording paper are widely used as continuous recording paper for recorders. And
From the standpoint of using a recorder, it is desirable that any recording paper can be used as necessary. For this reason, in the conventional recorder that uses a common type of recording paper, for example, a folding recording paper storage mechanism should be incorporated into the recorder main body as a standard feature, and the roll recording paper storage mechanism should be externally attached to the recorder main body as an optional specification. Has been done.

[0003]

However, in such a conventional configuration, since a mechanism for using the roll recording paper is provided externally, there are the following problems. The external dimensions increase. The mechanism is large and the cost is high.

Since the roll recording paper is exposed to the external environment, it is easily affected by the external environment, and the recording paper feeding operation and the recording quality may be unstable. The present invention is intended to solve these problems. The purpose of the present invention is to store folded recording paper and roll recording paper inside the recorder with a relatively simple structure, and to reduce the influence of the external environment on the recording paper. An object of the present invention is to realize a recording paper storage mechanism of a recorder which is hardly received.

[0005]

According to the present invention, a foldable recording paper or a roll recording paper stored in a recording paper storage portion is pulled out, wound around a part of a platen, and recorded by a recording head. A recording paper storage mechanism of a recorder that performs opening and closing, provided at one end with an opening / closing part, and a positioning groove provided on an inner side wall, and a folding recording paper that can be attached to and detached from the recording paper storage. A folding recording paper storage case, which is formed in a rectangular cylindrical shape so that it can be inserted, has an opening and closing part at one end, and a positioning pin that fits into a positioning groove of the recording paper storage part on the side, And a flange provided with a positioning pin that fits into the positioning groove of the recording paper storage section and detachably attached to both ends of the roll recording paper.

[0006]

[Function] When a foldable recording paper is used, a foldable recording paper storage case is attached to the recording paper storage section to store the foldable recording paper, and when a roll recording paper is used, the foldable recording paper is stored from the recording paper storage section. The paper storage case is removed, and the roll recording paper is stored through the flange.

[0007] As a result, the recording paper is stored inside the recorder regardless of which recording paper is used.
The effect of the external environment on the recording paper can be reduced.

In these figures, reference numeral 1 denotes a main body of a recorder, and a recording paper storage unit 2 in which a folding recording paper A (see FIG. 1) or a roll recording paper B (see FIG. 2) is stored in a lower part of the inside according to the application. Are formed. Reference numeral 3 denotes a platen, on which a fold recording paper A or a roll recording paper B stored in the recording paper storage unit 2 is pulled out and wound. Reference numeral 4 denotes a recording head, which is arranged to face the platen 3 so as to perform recording on the recording paper wound around the platen 3. 5
Reference numeral denotes a recording paper guide, which is formed so as to form the recording paper storage unit 2 and guide the recording paper drawn from the recording paper storage unit 2 to the platen 3. Reference numeral 6 denotes an opening / closing unit provided at the opening of the recording paper storage unit 2 via a hinge H1 so as to be openable / closable. Reference numeral 7 denotes a positioning groove provided on the inner side wall of the recording paper storage unit 2. In addition, the width of the opening of the recording paper storage unit 2 is provided with a gap of about 20 mm on each side of the width of the recording paper to be stored.

In FIG. 1, reference numeral 8 denotes a storage case for a foldable recording paper, which has an opening width substantially equal to the width of the foldable recording paper A so that it can be attached to and detached from the recording paper storage part 2 so that the foldable recording paper A can be inserted. It is formed in a tubular shape. An opening / closing unit 9 is provided at one end of the folded recording paper storage case 8 via a hinge H2 so as to be openable and closable, and a positioning pin 10 is provided on a side surface thereof so as to fit into the positioning groove 7 of the recording paper storage unit 2. I have. At the upper part, a recording paper guide 11 for guiding the folded recording paper A drawn from the recording paper storage unit 2 to the platen 3 is formed so as to be substantially continuous with the recording paper guide 5 of the recorder main body 1. The folding recording paper storage case 8 also has a reference positioning function of the folding recording paper A with respect to the recording unit.

In FIG. 2, reference numeral 12 denotes a flange which is detachably attached to both ends of the roll recording paper B, and a positioning pin 13 is provided at the center of the flange so as to fit into the positioning groove 7 of the recording paper storage section 2. . The operation of the recording paper storage mechanism of the recorder configured as above will be described. The operation can be divided into two cases: A: a case where the folded recording paper A is used (FIG. 1); and B: a case where the roll recording paper B is used (FIG. 2). Each case will be described.

<A: When Folded Recording Paper A is Used (FIG. 1)> In this case, the opening / closing section 6 is opened to open the opening of the recording paper storage section 2, and the folding recording is performed in the positioning groove 7 of the recording paper storage section 2. The positioning pin 10 of the paper storage case 8 is fitted, and the folding recording paper storage case 8 is mounted on the recording paper storage unit 2. Then, with the opening / closing section 6 open, the opening / closing section 9 of the folding recording paper storage case 8 is also opened to store the folding recording paper A in the recording paper storage section 2, and the end of the folding recording paper A is connected to the platen 3.
