Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roll recording paper storage mechanism, and more particularly, to improvement of operability associated with taking out roll recording paper from the recording paper storage unit.

[0002]

[Prior art]

 FIG. 3 is a partial sectional explanatory view showing an example of a conventional roll recording paper storage mechanism in a recorder using roll recording paper. In the figure, reference numeral 1 is a main body of a recorder, and a recording paper storage portion 2 for storing a roll recording paper RP is formed in a lower portion inside thereof. 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. Reference numeral 4 denotes a recording head, which is arranged so as to face 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 is formed to form the recording paper storage unit 2 and guide the recording paper pulled out from the recording paper storage unit 2 to the platen 3. Reference numeral 6 denotes an opening / closing portion which is provided in the opening of the recording paper storage portion 2 via a hinge 7 so as to be opened and closed. 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. Positioning pins 10 that fit into the positioning grooves 8 of the recording paper storage unit 2 are provided at the centers of these flanges 9.

When loading the roll recording paper RP into the recording paper storage unit 2, as shown in FIG. 4, flanges 9 are fitted to both ends of the roll recording paper RP, and positioning pins 10 protruding from the flange 9 are positioned. Fit in the groove 8 and slide.

[0004]

[Problems to be solved by the device]

 However, in such a conventional configuration, when the roll recording paper RP is taken out from the recording paper storage unit 2 and the remaining amount of the roll recording paper RP is large, as shown in FIG. 5, the recording paper guide 5 and the roll recording paper RP are shown. Since the gap G between and becomes narrower, there is a problem that the finger cannot be inserted and it is difficult to perform the removing work.

The present invention solves such a problem, and an object thereof is a roll recording paper storage mechanism having a relatively simple structure and capable of easily taking out the roll recording paper from the recording paper storage unit. Is to realize.

[0006]

[Means for Solving the Problems]

 According to the present invention which solves such a problem, an opening / closing part is provided on the front surface, and a recording paper storage part having a positioning groove on the inner side wall is fitted to a positioning groove of the recording paper storage part at the center. Flanges that are detachably attached to both ends of the roll recording paper, and one end that is fixed to the positioning pin that protrudes from the flange, and the other end that can be expanded and contracted so that it can be selectively pulled out from the peripheral edge of the flange. It is characterized in that it is configured with an operation knob formed.

[0007]

[Action]

 When removing the roll recording paper from the recording paper storage, pull out the end of the operation knob and remove the positioning pin from the positioning groove. As a result, even if the gap between the recording paper guide and the roll recording paper is narrow, the take-out operation will not be hindered as in the past.

Further, since the operation knob is formed to be expandable and contractible, and one end thereof is fixed to the positioning pin protruding from the flange, the end portion of the operation knob in a state where the roll recording paper is stored in the recording paper storage unit. 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 for providing the operating knob.

[0009]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view showing the configuration of an embodiment of the present invention, in which parts common to those in FIGS. 3 to 5 are designated by common reference numerals. In the figure, reference numeral 20 is 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 formed so as to be extendable and retractable so as to be selectively pulled out from the peripheral edge of the flange 9.

FIG. 2 is a partial cross-sectional configuration explanatory diagram of a specific example of such an operation knob 20. Reference numeral 21 denotes a shaft having a stepped portion, and a small diameter portion is inserted into a boss 22 and an E ring 23 is fitted around the end portion of the small diameter portion as a retaining member. Reference numeral 24 denotes a pipe-shaped moving body having one end opened and the other end closed, and the boss 22 is press-fitted into the opening to be integrated with the knob 24. As a result, the moving body 24 can slide along the boss 22 with respect to the shaft 21 in the axial direction, and can expand and contract. Such an operation knob 20 is fixed to the positioning pin 10 by pressing 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 thus configured will be described. First, when loading the roll recording paper RP into the recording paper storage unit 2, as shown in FIG. 4, the flanges 9 are fitted to both ends of the roll recording paper RP as in the conventional case, and the positioning pins protruding from the flange 9 are inserted. 10 is fitted in the positioning groove 8 and slid.

On the other hand, when taking out the roll recording paper RP from the recording paper storage unit 2, pull out the ends of the moving bodies 24 of the operation knobs 20 on both sides of the roll recording paper RP along the axial direction of the shaft 21. The end of the operation knob 20 is projected from the peripheral edge of the flange 9. Then, by further pulling out the end portion of the operation knob 20, the positioning pin 10 is pulled out along the positioning groove 8 and disengaged from the positioning groove 8.

As a result, even if the gap G between the recording paper guide 5 and the roll recording paper RP is narrow as shown in FIG. 5, the end portion of the operation knob 20 can be pulled out, and there is no obstacle to the removal work as in the past. It never happens. Further, since the operation knob 20 is formed to be expandable and contractible and one end thereof is fixed to the positioning pin 10 protruding from the flange 9, the operation knob 20 is in a state where the roll recording paper RP is stored in the recording paper storage unit 2. The end portion of the recording sheet storage section 2 does not protrude from the peripheral edge of the flange 9, and the space for the recording sheet storage section 2 does not need to be large because the operation knob 20 is provided.

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