Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roll paper holder for holding roll paper such as recording paper in a facsimile receiver or printer.

Conventionally, as a roll paper holder, a positioning member is movably provided on a curved plate-shaped receiving member that receives the rolled paper, and the position of the positioning member is changed depending on the width of the rolled paper placed on the receiving member. It is known what has been done.

However, this roll paper holder has a complicated means for positioning the roll paper.

The object of the present invention is to provide a paper roll holder that can hold both wide and narrow rolls of paper, and
To provide a roll paper holder having a simple structure.

The present invention will be explained in detail based on the illustrated embodiments below.

FIG. 1 shows an embodiment in which the roll paper holder of the present invention is used in a facsimile receiver.
In FIG. 1, reference numeral 1 indicates a roll paper holder. A roll paper 2 made of wound recording paper is placed on the roll paper holder 1. The end of this roll paper 2 is connected to the recording head 3 and the back roller 4.
The paper is transported by a paper transport means (not shown) while being inserted between the paper sheets.

As shown in FIG. 2, the roll paper holder 1 has a wide receiving portion 1b having side plates 1a on both sides.
and a small-width receiving portion 1c provided with a step downward in the middle of the large-width receiving portion 1b, and side walls 1d are formed on both sides of the narrow-width receiving portion 1c. The upper surfaces of the large-width receiving section 1b and the narrow-width receiving section 1c that receive the roll paper 2 are curved surfaces with a concave center.

When placing a large roll paper 2 on the roll paper holder 1, both ends of the roll paper 2 are received by the large width receiving portion 1b, and the roll paper 2 is placed on the side plate 1.
Positioning in the width direction is performed by a. When placing a narrow roll paper 2 on the roll paper holder 1, the roll paper 2 is received by the narrow width receiving part 1c,
Moreover, the roll paper 2 is positioned in the width direction by the side wall 1d of the narrow width receiving part 1c. Therefore, as shown in FIG. 3, when the wide roll paper 2 is placed on the roll paper holder 1, it is placed at the position shown by the solid line, and the narrow roll paper 2 is placed on the roll paper holder 1. When placed, it is placed at the position shown by the one-dot chain line.

Another embodiment of the present invention is shown in FIGS. 4 and 5 and will be described next.

In the embodiment shown in FIGS. 4 and 5,
The small-width receiving member 1c is arranged to be rotatable about the support shaft 1e relative to the wide-width receiving member 1b. The rotating end of the small width receiving member 1c is a pressing spring 1.
It is pressed upward by f. Small width receiving member 1c
Two stoppers 1g and 1h are arranged vertically at a predetermined distance apart from each other on the rotating end side. The upper stopper 1g is fixed to a predetermined immovable member. The lower stopper 1h is rotatably attached to the shaft 1i. By operating the narrow width receiving member 1c and the stopper 1h with fingers, the narrow width receiving member 1c can be locked with either the stopper 1g or 1h.

The above narrow width receiving member 1c is the upper stopper 1g
If the narrow width receiving member 1c is locked by
The top surface of the lower part of is almost the same as the top surface of the lower part of the large width receiving member 1b, and in this state, the large roll paper 2 is placed on the roll paper holder 1.

The above narrow width receiving member 1c is the lower stopper 1h
If the narrow width receiving member 1c is locked by
The upper surface of the lower part of the width receiving member 1b has a step downwardly from the upper surface of the lower part of the wide receiving member 1b. In this state, the narrow width roll paper 2 is placed on the narrow width receiving member 1c, and
The roll paper 2 is positioned in the width direction by the end of the wide width receiving member 1b on the narrow width receiving member 1c side.

If the difference in width between the wide roll paper 2 and the narrow roll paper 2 is small, if only both ends of the wide roll paper 2 are supported by the small side, the roll paper 2 may wrinkle or be scratched due to its own weight. However, in the embodiment shown in FIGS. 4 and 5, both the narrow roll paper 2 and the wide roll paper 2 are received by the large surface, so the roll paper 2 is prevented from being wrinkled or scratched. It can be effectively prevented.

Another embodiment of the present invention is shown in FIGS. 6 and 7 and will be described next.

In FIG. 6, reference numeral 5 indicates a large receiving box. On one side of this large width receiving box 5 is a small width receiving box 6.
is provided. Bottom plate 5a of the above large receiving box 5
A hole 5b is formed in the hole 5b. A support shaft 7 is fixed to the bottom plate 5a of the wide receiver box 5 below near the hole 5b. A curved receiving plate 8 is arranged inside the wide receiving box 5, and the lower part of this receiving plate 8 is inserted through the hole 5b of the bottom plate 5a, and the support shaft 7
It is rotatably supported. A pressing spring 9 is provided between the receiving plate 8 and the bottom plate 5a of the wide receiving box 5, and this spring 9 presses the receiving plate 8 upward.

As shown by the solid line in FIG. 7, a wide roll paper 2 is placed between the receiving plate 8 and the side plate 5c of the wide width receiving box 5 on the narrow width receiving box 6 side. The spring 9 is compressed by the weight of the receiving plate 8.
is placed on the receiving plate 8 in a downwardly rotated state as shown in FIG. The wide roll paper 2 is positioned in the width direction by the side plate 5d of the wide roll paper receiving box 5.

A narrow roll paper 2 is placed in the narrow width receiving box 6 as shown by the dashed line in FIG. 7, and in this case the receiving plate 8 is in pressure contact with the roll paper 2. The narrow-width roll paper 2 is positioned in the width direction by the side plate 6a of the narrow-width receiving box 6.

Also in the embodiment shown in FIGS. 6 and 7,
Similar to the embodiments shown in FIGS. 4 and 5, the narrow roll paper 2 and the wide roll paper 2 are received by the large surface, so that wrinkles and scratches on the roll paper 2 are effectively prevented. be able to.

The roll paper holder of the present invention can hold both wide roll paper and narrow roll paper, and has a simple configuration.
