DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll paper accommodating apparatus for rotatably accommodating roll paper in a recording apparatus using roll-shaped recording paper (hereinafter referred to as roll paper).

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
A storage unit 3 that forms a roll paper storage device that stores roll paper is formed, the roll paper 2 is simply dropped and held in the storage unit 3, and the recording paper is pulled out from the roll paper 2 via the roller 4, There is known a facsimile apparatus which is configured to perform recording by the recording head 6 while transporting the recording paper at the position 5. Normally, a sheet-like member 7 having a smooth surface is provided on the inner surface (bottom surface and side surface) of the housing portion 3 so that the roll paper can be easily rotated while contacting the outer peripheral surface thereof.
Is provided. As shown in FIG. 5, the sheet member 7 includes a smooth surface member 7a such as a resin film having good slip and an adhesive member (for example, a double-sided adhesive tape) 7b for bonding the smooth surface member 7a to the inner surface of the housing portion 3. Was used, and did not have cushioning properties.

[0003]

However, the roll paper storage device having such a configuration has a problem that abnormal noise is generated while the recording paper is being fed from the roll paper.

The present inventors have studied the causes of the abnormal noise and found the following. That is, since the roll paper rotates in the storage section 3 when the recording paper is pulled out, the outer peripheral surface of the roll paper needs to slip with respect to the smooth surface member 7a.
Vibration occurs in the roll paper. This vibration propagated to the housing 3 and the entire device, and caused abnormal noise.

In order to absorb the vibration, it is conceivable to provide a felt having a cushioning property on the surface of the housing portion 3 and to support the roll paper with the felt. However, in this case, a problem has occurred in that the surface of the roll paper, for example, the surface of the heat-sensitive recording paper is damaged due to the roughness of the felt surface.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and a roll capable of absorbing the vibration of the roll paper and preventing the generation of abnormal noise without damaging the roll paper surface. It is an object to provide a paper storage device.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention solves the above-mentioned problems. Conveying means for feeding out the roll paper with the outer peripheral surface of the paper as the upper surface, and
A roll is placed on the bottom without being placed on the opposite side.
The roll so that it always contacts regardless of the diameter of the paper
With a predetermined width in the direction perpendicular to the longitudinal direction of the paper,
Elasticity is provided at the position including the center of the roll paper storage section
Having a cushion layer having a surface and a smooth surface layer
Each time the transport means unwinds the roll paper.
The roll paper is tilted to the side where it is fed out while the roll paper is
Has a large contact surface with the cushion material when the diameter is large.
The configuration is such that the user can make contact with

[0008]

DETAILED DESCRIPTION OF THE INVENTION The present invention by the above-described configuration, the conveying means
Roll paper should be pulled out with its outer peripheral surface facing up.
Because of this, the roll paper leans in the transport direction,
The paper does not touch the side without cushioning material,
The cushioning material placed on the bottom of the roll paper storage
Roll so that it always contacts regardless of the diameter of the roll paper
Provide a predetermined width at the position including the center of the bottom of the paper
Roll paper, which is in a heavy condition
When the contact area is large, take a large
Can touch and protect the surface of the roll paper.
Wear.

FIG. 1 is a schematic side view of a part of a facsimile apparatus provided with a roll paper accommodating apparatus according to an embodiment of the present invention. The same parts as those of the conventional example of FIG. I have. In FIG. 1, reference numeral 1 denotes a housing, 2 denotes roll paper, 3 denotes a storage unit constituting a roll paper storage device that stores the roll paper, 4 denotes rollers, 5 denotes transport rollers, and 6 denotes a recording head.

The housing 3 is usually formed integrally with the housing 1 by molding resin. Roll paper 2 of this storage section 3
(For example, bottom surface 3A and side surface 3A)
B) is provided with a cushion material 9. As shown in an enlarged manner in FIG. 2, the cushion material 9 includes a surface layer 9a having a smooth surface, an elastic cushion layer 9b on the back side thereof, and an adhesive member 9c for adhering these to the housing portion 3. And The surface layer 9a is made of a smooth film material having a smooth surface, for example, a polyester film or the like, and has a thickness of, for example, 0.1 mm.
It is about. As the cushion layer 9b, an elastic material such as felt and sponge can be used as appropriate, and the thickness thereof is preferably about 0.5 to 1.0 mm. Adhesive member 9c
Any material may be used as long as the cushion layer 9b can be adhered to the housing portion 3. For example, a double-sided adhesive tape having a thickness of about 0.1 mm can be used. Note that the bonding member 9c may be omitted, and the cushion layer 9b may be directly bonded to the housing section 3 with an adhesive or the like. The mounting position of the cushion material 9 is a position where the cushion paper 9 can come into contact with the roll paper 2 regardless of whether the diameter of the roll paper 2 is large as shown in FIG. 1 or small as shown in FIG. Stipulated.

In the roll paper accommodating apparatus configured as described above, the roll paper 2 always contacts the cushion material 9 and slips against the cushion material 9, but the surface of the cushion material 9 has a smooth surface. It is easy to slip and does not cause scratches due to slip. Further, at this time, even if vibration occurs in the roll paper 2 due to the occurrence of the stick-slip, the vibration is absorbed by the cushion layer 9 b and does not transmit the vibration to the storage section 3. Thus, generation of abnormal noise can be prevented.

[0012]

As is clear from the above description, the roll paper is drawn out by the transport means so that the outer peripheral surface of the roll paper faces upward, so that the roll paper is bent in the transport direction.
Roll paper without the side surface of the absence of the cushion material side contact, contact with a cushion member disposed on the bottom surface central portion, further large-diameter roll paper is heavy state of roll paper
When it is hard, take a large area of the contact
By contacting the material, the surface of the roll paper can be protected efficiently.
It has the effect that it can be. Also,
Since the unnecessary portion not arranged cushion material, Kos
It can contribute to downtime.
