[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll recording paper storage mechanism, and more particularly, to an improvement in operability accompanying removal of a roll recording paper from a recording paper storage section.

[0002]

2. Description of the Related Art FIG. 3 is a partially sectional explanatory view showing an example of a conventional roll recording paper storage mechanism in a recorder using roll recording paper. In the figure, 1 is the main body of the recorder,
A recording paper storage unit 2 for storing the roll recording paper RP is formed in a lower part of the inside. Reference numeral 3 denotes a platen, on which a roll recording paper RP stored in the recording paper storage unit 2 is pulled out and wound. 4 is a recording head,
It is arranged opposite to the platen 3 so as to perform recording on the recording paper wound around the platen 3. Reference numeral 5 denotes a recording paper guide, which forms the recording paper storage section 2 and guides the recording paper pulled out from the recording paper storage section 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 7 so as to be openable / closable.
Reference numeral 8 denotes a positioning groove provided on the inner side wall of the recording paper storage unit 2. Reference numeral 9 denotes a flange, which is detachably attached to both ends of the roll recording paper RP as shown in FIG. At the center of these flanges 9, there are provided positioning pins 10 which fit into the positioning grooves 8 of the recording paper storage section 2.

When loading the roll recording paper RP into the recording paper storage section 2, as shown in FIG.
Flanges 9 are fitted to both ends of P, and positioning pins 10 protruding from flange 9 are fitted into positioning grooves 8 and slid.

[0004]

However, in such a conventional configuration, when the roll recording paper RP is taken out of the recording paper storage unit 2 when the remaining amount of the roll recording paper RP is large, as shown in FIG. Recording paper guide 5 and roll recording paper RP
There is a problem that the finger cannot enter because the gap G with the gap becomes narrow, and it is difficult to take out the work.

The present invention is intended to solve such a problem, and an object of the present invention is to provide a roll recording paper storage mechanism capable of easily taking out a roll recording paper from a recording paper storage section with a relatively simple structure. Is to make it happen.

[0006]

According to the present invention, there is provided a recording paper storage section having an opening / closing section on the front surface and a positioning groove on an inner side wall, and a recording sheet at the center. A positioning pin that fits into the positioning groove of the paper storage unit is provided, and a flange detachably attached to both ends of the roll recording paper, one end is fixed to a positioning pin protruding from the flange, and the other end is selected from the periphery of the flange. And an operation knob formed so as to be extendable so as to be able to be pulled out.

[0007]

When taking out the roll recording paper from the recording paper storage section, the positioning pin is removed from the positioning groove while pulling out the end of the operation knob. Thus, even when the gap between the recording paper guide and the roll recording paper is small, there is no problem in taking out work as in the related art.

Further, the operation knob is formed to be extendable and contractable, and one end is fixed to a positioning pin protruding from the flange. Therefore, when the roll recording paper is stored in the recording paper storage part, the end of the operation knob is moved. It does not protrude from the peripheral edge of the flange, and it is not necessary to increase the space of the recording paper storage section to provide the operation knob.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration explanatory view showing an embodiment of the present invention,
3 to 5 are denoted by the same reference numerals. In the figure, reference numeral 20 denotes an operation knob, one end of which is fixed to a positioning pin 10 protruding from the flange 9, and the other end of which is extendably formed so as to be selectively pulled out from the periphery of the flange 9.

FIG. 2 is a partially sectional structural explanatory view of a specific example of such an operation knob 20. As shown in FIG. Reference numeral 21 denotes a shaft having a stepped portion. The small-diameter portion is inserted into the boss 22 and an E-ring 23 is fitted near an end of the small-diameter portion as a stopper. Reference numeral 24 denotes a pipe-shaped moving body having one end opened and the other end closed, and a boss 22 is press-fitted into the opening to be integrated with the knob 24. Thereby, the moving body 24
Can slide along the shaft 21 with the boss 22 in the axial direction, and can expand and contract. The operation knob 20 is fixed to the positioning pin 10 by press-fitting the end of the shaft 21 into the side surface of the positioning pin 10 protruding from the flange 9.

The operation of the roll recording paper storage mechanism configured as described above will be described. First, when loading the roll recording paper RP into the recording paper storage unit 2, as shown in FIG.
And the positioning pin 1 protruding from the flange 9
0 is fitted into the positioning groove 8 and slid.

On the other hand, when removing the roll recording paper RP from the recording paper storage unit 2, the roll recording paper RP
The ends of the moving body 24 of the operation knob 20 on both sides of the
1 is pulled out along the axial direction, and the end of the operation knob 20 is projected from the peripheral edge of the flange 9. By further pulling out the end of the operation knob 20, the positioning pin 10
Is pulled out along the positioning groove 8 and comes off the positioning groove 8.

As a result, even when the gap G between the recording paper guide 5 and the roll recording paper RP is narrow as shown in FIG. Will not occur. The operation knob 20
Is formed to be extendable and contractable, and one end is fixed to a positioning pin 10 protruding from the flange 9. Does not protrude from the periphery of the recording paper storage unit 2 to provide the operation knob 20.

The configuration of the operation knob 20 is not limited to the embodiment, but may be any configuration that can be substantially expanded and contracted.

[0015]

[Effects of the Invention] As described above, according to the present invention,
With the relatively simple structure, a roll recording paper storage mechanism that can easily take out the roll recording paper from the recording paper storage section can be realized.
