DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a recording paper supporting device for supporting a roll of recording paper in, for example, a calculator with a printer.

[0002]

2. Description of the Related Art For example, in a device having a small printer unit, such as a calculator with a printer, a roll of recording paper for printing is used. The roll-shaped recording paper is projected and supported outside the printer unit. A conventional roll paper support device is disclosed in, for example, Japanese Patent Application Laid-Open No. 57-41756. FIG. 7 is a diagram showing a configuration example of a conventional roll-shaped recording paper support device. A paper holder 52 protrudes from the rear of the printer unit 51, and a roll-shaped recording paper 53 is supported at the leading end thereof. The recording paper 53 is pulled out from the lower side of the roll body, and is discharged to the upper surface of the printer unit 51 via the printing unit in the printer unit 51.

[0003]

However, in the conventional recording paper supporting apparatus as shown in FIG. 7, since the paper holder 52 protrudes to the rear of the printer section 51, the exclusive use of the printer including the recording paper 53 is required. There was a problem that the area became large. In particular, even when the printer unit is not required, there is a problem because the paper holder 52 projects greatly behind the printer unit. Further, in the case where the device provided with the printer unit is portable, for example, a calculator or the like, since the paper holder 52 protrudes greatly outside the printer unit as described above, it becomes inconvenient to carry. There was a problem.

[0004] It is an object of the present invention to provide a recording paper supporting device capable of saving space in a printer section.

[0005]

According to the present invention, there is provided a paper holder in which one end supports a roll-shaped recording paper and the other end is rotatably supported by a printer main body, and a paper holder is provided on a part of the paper holder.
The angle at which the paper holder is sexually engaged and the paper holder is supported by the printer body is folded over the top of the printer body.
Angle to be folded, one end of paper holder after printer

FIG. 1 is a view showing the appearance of a calculator provided with a recording paper supporting device, and FIG. 2 is a view showing a schematic configuration of the calculator.

The calculator main body includes a keyboard 1, a display panel 2,
The printer unit 3 is provided. Keyboard 1 is a numeric keypad,
An operation key, an instruction key, and the like are provided. The display panel 2 is, for example, a liquid crystal panel on which calculation results and the like are displayed.
The calculation result and the like are printed on the recording paper 10 by the printer unit 3.

The printer section 3 has a printing device (not shown) inside the calculator main body. The printing device includes, for example, a thermal head and an ink ribbon. Further, the printer section 3 includes a recording paper support device 4. The recording paper supporting device 4 includes a paper holder 5, a roller (not shown) for transporting recording paper provided inside the calculator main body, a paper guide 6a,
6b, a paper cutter 7, a guide rib 8, and the like.

FIG. 3 is a view showing a state where the paper holder is attached to the calculator main body, and FIG. 4 is a view showing the paper holder. The arm portion 5a of the paper holder 5 is formed substantially in an L shape. At the upper end of the arm 5a, a support 5b for supporting a roll-shaped recording paper is provided.
Is provided at its lower end with a pivoting portion 5c which makes the arm portion 5a (paper holder main body) pivotable. A support bar 9 protrudes from the support portion 5b. The recording paper 10 in the form of a roll is inserted into the support rod 9 and is supported by the pressing member 9a so as not to fall off the support rod 9.
The rotating part 5c is provided with a rotating shaft 11. Rotation axis 1
As shown in FIG. 3, one end of 1 is embedded in the support rod 9 and the arm 5a, and the other end is rotatably supported by the calculator main body. FIG. 4 shows a side view of the rotating portion 5c.
As shown in (B), engagement holes 12a, 12b, and 12c are provided. The engaging members 1 are provided in the engaging holes 12a to 12c.
3 are engaged. The engagement member 13 is provided so as to be movable in a direction perpendicular to the surface of the rotating portion 5c. Further, the engaging member 13 is urged by a spring 14 and is pressed against the surface of the rotating portion 5c.

The engaging member 13 is engaged with one of the engaging holes 12a to 12c. When the engaging member 13 is engaged with the engaging hole 12a, the paper holder is held at the position 5 'in FIG.

Similarly, when the engaging member 13 is engaged with the engaging hole 12b, the paper holder is held at the position 5 in FIG.
When the engaging member 13 is engaged with the engaging hole 12c, the paper holder is held at the position 5 "in Fig. 2. When the paper holder is at the position 5", the recording paper 10 is located above and behind the calculator main body. Thus, the occupied area of the calculator increases, but the recording paper does not hinder the operation of the calculator. When the paper holder is at the position 5, the recording paper 10 is located above the calculator main body, so that the occupation area of the calculator does not increase.
The paper holder is folded at the 5 'position,
The paper holder 5 does not get in the way when carrying the calculator. Rotate the paper holder to 5,5 ',
The position of the paper holder 5 is changed by applying (pushing) an external force to the paper holder 5. When the engagement member 13 is engaged with any of the engagement holes 12a, 12b, and 12c, the paper holder 5 is moved. When the turning force is applied, the engaging member 1
3 is pressed against the wall surface of the paper holder 5, and the two are disengaged against the urging force of the spring 14. When the engaging member 13 is engaged with another engaging hole (any one of 12a, 12b, and 12c) and the external force is removed, the engaging member 13 is moved into the engaging hole by the urging force of the spring 14. Engage. Thus, the position of the paper holder 5 can be changed.

The recording paper 10 pulled out of the roll body in the printer section passes through the inside of the printer body, and is then discharged outside the printer section by the paper guides 6a and 6b. The paper cutter 7 cuts the paper after printing.
By the way, when the paper holder is at the position 5 in FIG. 2, the leading end of the recording paper discharged from the printer unit is discharged toward the recording paper roll 10. Therefore, if left as it is, the leading end of the recording paper is caught in the roll. Therefore, a guide rib 8 is provided to prevent the recording paper from being entangled. FIG. 5 is a view showing the guide rib 8. The guide rib 8 is provided with a return claw 8a at an upper end portion and an insertion portion 8b at a lower portion. By inserting the insertion portion 8b into a hole (not shown) provided at the upper end of the paper guide 6a, the guide rib 8 is fixed to the printer portion. The operation of discharging the recording paper 10 will be described. FIG. 6 is a diagram showing a state when the recording paper is discharged. The recording paper 10 is discharged along the paper guide 6a, and further, the guide rib 8 above the paper guide 6a.
It is discharged along. Then, the leading end of the recording paper 10 hits the return claw 8a of the guide rib (dashed line 10 '), and is prevented from moving in the traveling direction and bends (dotted line 1).
0 ″). Thereby, the discharge direction of the recording paper 10 is changed, and the recording paper 10 is discharged without being caught in the roll body (solid line 10).
