[0002]

2. Description of the Related Art In recent years, an image forming apparatus (for example, a printer, a copier, etc.) capable of forming an image on a large sheet of, for example, the first row in row A has been considered. Most of these image forming apparatuses use a so-called roll paper in which continuous paper is wound around a mandrel. In the apparatus, in addition to a mechanism for forming an image, a space for storing the roll paper is provided. A mechanism for cutting the roll paper.

FIG. 2 is a schematic configuration diagram illustrating a conventional printer 73 using a roll paper 71. Caster 75
A recording head 81 is provided in an upper part of the frame 77 which is configured to be movable by the above, and a platen roller 83 is arranged below the recording head 81 to face the recording head 81. Below the platen roller 83, the roll paper 71 is rotatably stored with its mandrel 71a arranged in parallel with the platen roller 83. The roll paper 71 is guided to the surface of the platen roller 83 via the rollers 85 and 87, and is discharged out of the frame 77 through the space between the platen roller 83 and the recording head 81.

[0004] A cutter 89 is provided in a frame 77 on the downstream side of the platen roller 83 in the transport path of the roll paper 71. Further, rollers 91 and 93 for spreading the roll paper 71 over the platen roller 83 are provided above and below the recording head 81.

In the printer 73 configured as described above,
The platen roller 83 and the recording head 81 are driven based on a signal from a personal computer (not shown) or the like, and an image is formed on the surface of the roll paper 71 while being fed. After the image formation, the platen roller 83 is driven to further transport the roll paper 71, and then the cutter 89 is driven to cut the roll paper 71 into a desired length. In such a printer 73, an image can be easily formed on a large-sized sheet (roll sheet 71).

[0006]

However, such a printer 73 requires a large frame 77 for accommodating a large roll paper 71. Therefore, the printer 7
3 requires a large installation space. Also, the roll paper 7
1 includes various papers such as an illuminated film and synthetic paper (so-called YUPO paper) in addition to high-quality paper used as general copy paper, and these are used as needed. If the roll paper 71 is replaced every time the type of the roll paper 71 to be used is changed, the workability is poor. Therefore, it is conceivable to store a plurality of types of roll paper 71 in the frame 77 in advance. The frame 77 is further enlarged. Therefore, a wider installation space is required.

Accordingly, the present invention reduces the installation space of an image forming apparatus for forming an image on roll paper,
It is an object of the present invention to provide a roll paper holding device that can improve the workability of the image forming apparatus.

[0008]

Means for Solving the Problems and Effects of the Invention According to the first aspect of the present invention, there is provided a roll paper holding device for holding a roll paper so as to be able to be fed out to an image forming apparatus. Holding means for holding a plurality of roll papers so that their axes are parallel and capable of being individually fed out, and the axis of the roll paper held by the holding means is orthogonal to the paper transport direction to the image forming apparatus. Connecting means for detachably connecting the roll paper holding device main body to the image forming apparatus.

In the roll paper holding apparatus of the present invention thus configured, the holding means holds a plurality of roll papers so that their axes are parallel and can be individually fed. Further, when this roll paper holding device main body is connected to the image forming apparatus via the connecting means, the roll paper held by the holding means is arranged so that the axis thereof is orthogonal to the direction in which the paper is transported to the image forming apparatus. .

For this reason, the image forming apparatus can form an image by directly feeding out the roll paper from the roll paper holding device without providing a structure for storing the roll paper in the image forming device. Moreover, if the connecting means is removed, the roll paper holding device main body can be separated from the image forming apparatus. Therefore, the installation space for the image forming apparatus can be satisfactorily reduced. Further, since the holding means holds the plurality of roll papers so as to be individually fed, the desired one of the plurality of roll papers can be fed toward the image forming apparatus without replacing the roll papers. . Therefore, the workability of the image forming apparatus can be improved satisfactorily.

According to a second aspect of the present invention, in addition to the configuration of the first aspect, the roll paper fed from the holding means is curved in a direction opposite to a direction in which the roll paper was previously wound, and the roll paper is wound. It is characterized in that correction means for correcting the habit are further provided. When rolled paper is held in a wound state for a long period of time, the paper has a curl. In this case, the roll paper is wavy at the time of image formation, and a good image is not formed, or the paper after image formation is curled and inconvenient to handle. On the other hand, in the present invention, by the correction means,
The roll paper unreeled from the holding means can be curved in a direction opposite to the direction in which the roll paper was previously wound, thereby correcting the curl of the roll paper. Therefore, in the present invention, claim 1
In addition to the effects of the invention described above, there is an effect that the workability of the image forming apparatus can be further improved and the image quality of the image formed by the image forming apparatus can be improved.

The invention described in claim 3 is the first or second invention.
In addition to the configuration described above, a cutting unit for cutting the roll paper fed from the holding unit to a desired length is further provided. In the present invention, the cutting unit cuts the roll paper fed from the holding unit to a desired length. Therefore, it is not necessary to provide a cutting unit such as the cutter 89 in the image forming apparatus. Therefore, in the present invention, claim 1
Or, in addition to the effect of the invention described in 2, the effect that the installation space of the image forming apparatus can be further reduced.

According to a fourth aspect of the present invention, in addition to the configuration of any one of the first to third aspects, when the roll paper holding device main body is separated from the image forming apparatus by removing the connecting means, the roll paper is removed. Moving means for moving the holding device body,
It is further characterized by being provided.

In the present invention, when the connecting means is disconnected to separate the roll paper holding device main body from the image forming apparatus, the moving means moves the roll paper holding device main body. For this reason, it is extremely easy to arrange the roll paper holding device separately from the image forming device and to connect the roll paper holding device to the image forming device as needed. If the roll paper holding device has been connected to the image forming apparatus for a long time, the effect of reducing the installation space of the image forming device does not appear so remarkably, but by excluding both at the time of image formation, The above effect becomes very remarkable. Therefore, in the present invention, in addition to the effect of the invention described in any one of the first to third aspects, an effect that the installation space of the image forming apparatus can be more easily reduced is produced.
