Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus using roll paper as recording paper, and more particularly to a roll paper holding structure.

[0002]

2. Description of the Related Art This type of recording apparatus is used in small facsimile machines, copying machines, printers, etc., and the following roll paper holding structure is known.

The first is a simple structure in which a semi-cylindrical roll paper holder is provided inside the apparatus and the roll paper is placed directly on it.

The second one is disclosed in Japanese Unexamined Patent Publication No. 4-32446, and is for regulating the end face position of the roll paper in a semi-cylindrical roll paper holder (roll paper storage section) inside the apparatus. The partition plates are removably attached at intervals corresponding to the width of the roll paper. This is a structure in which the roll paper is held by setting the roll paper between the partition plates and engaging both ends of the spool inserted into the paper core of the roll paper with the holding grooves provided in the partition plate.

A third type is disclosed in Japanese Utility Model Publication No. 4-12441, and a plurality of foldable partition plates (holders) are provided inside the apparatus at positions corresponding to the width size of the roll paper. Raise a partition plate corresponding to the width size of the roll paper to be used, tilt down the other roll paper holder, and engage both ends of the spool or spindle inserted into the roll paper core with the holding groove of the upright partition plate. This is the structure for holding the roll paper.

[0006]

However, the roll paper holding structure described above has the following problems to be solved.

In the first structure, when the diameter of the roll paper is large, the inertial weight of the roll paper is large, so that the scaling ratio is likely to be off due to the sliding of the platen roller. As a countermeasure against this, if it is attempted to suppress the slippage of the platen roller by increasing the pressing force of the platen roller, the drive load of the platen roller increases, resulting in an increase in the size of the platen roller drive motor and an increase in cost. The width of the roll paper holder is set slightly larger than the maximum width of the roll paper in consideration of variations in the width of the roll paper. When the diameter of the roll paper becomes small, the roll paper tends to tilt, the amount and direction of tilt are not constant, and the correction ability is small. As a result, unstable skew of the recording paper occurs,
In the worst case, there was a problem that the recording paper was damaged or jammed.

Similar to the first structure, the second and third structures must have a margin for the space between the partition plates with respect to the width size of the roll paper, so that the same skew problem occurs. There is. Furthermore, it is necessary to prepare a spool or spindle for inserting into the paper core of the roll paper, which contributes to cost increase, and it is necessary to remove the spool or spindle when replacing the roll paper. There is a problem that the roll paper replacement work is troublesome. Further, the third structure has a problem that the number of partition plates increases and the cost increases in order to cope with various roll papers having different width sizes.

Further, in any of the first to third structures, it is not easy to downsize the apparatus because it is necessary to secure a space for holding the rolled paper inside the apparatus. There is also the problem that it cannot be set.

It is an object of the present invention to provide a recording apparatus which improves the above-mentioned problems relating to holding roll paper.

[0017]

According to the present invention, the pair of support pins are inserted into each end of the paper core of the roll paper to support the roll paper, so that the roll paper is directly placed in the storage space. In comparison, the difference in transport resistance due to changes in the diameter of roll paper is small,
Also, since the transport resistance can be reduced, slipping of the recording paper is less likely to occur without increasing the pressing force of the platen roller, and it is easy to prevent deviation of the scaling ratio in the sub-scanning direction, and the drive load of the platen roller The size of the drive motor can be reduced, and the drive motor can be prevented from increasing in size. Further, a sleeve or a spindle for inserting the roll paper into the paper tube is not required, and by changing the fixing position of the partition plate or the holding arm, various roll papers having different width sizes can be held.

According to the first or fifth aspect of the present invention, at least one of the pair of surface portions for engaging with the end surface of the roll paper to regulate the position of the roll paper in the thrust direction is elastic, and one end surface of the roll paper is elastic. Since the sheet is pressed and biased, the movement of the roll paper in the thrust direction can be regulated and the inclination of the roll paper can be corrected.

According to the second aspect of the present invention, the recording apparatus can be miniaturized because it is not necessary to secure a space for containing the roll paper in the apparatus. Further, by increasing the protrusion amount of the holding arm, it is possible to easily use a large-diameter roll paper that is difficult to store in the apparatus.

An image is formed on the recording paper passing through the thermal head 7 by selectively energizing the heating elements of the thermal head 7 by the image data supplied from the control / power supply unit 10. The recording paper on which the image is formed passes through the cutter 6 and is discharged to the recording paper tray 1 by the paper discharge roller 3. The recording paper is cut by the cutter 6 at a predetermined position after the recording of the image of one page is completed. The cut recording paper is returned to the thermal head 7 side by a predetermined amount by the reverse rotation of the platen roller 8 to prepare for the next recording.

As shown in FIG. 2, a support pin 13a provided on one side 12a of the roll paper holder 12 is provided.
And the support pins 13b provided on the partition plate 14 are inserted into both ends of the paper tube (core tube) 30 of the roll paper 9, whereby the roll paper 9 is rotatably supported in the roll paper holder 12. . The support pin 13a is the roll paper holder 12
It can be formed as a separate member and fixed, or can be formed integrally with the roll paper holder 12 using resin or the like.

The partition plate 14 has a position shown in FIG. 2 or a broken line 14b depending on the width size of the roll paper 9 used.
It can also be installed in the position shown in. The support pin 13b can be formed as a member independent of the partition plate 14, or can be integrally formed with the partition plate 14 using resin or the like.

FIG. 3 is a schematic perspective view showing an example of the partition plate 14. The partition plate 14 shown here is integrally formed of an elastic resin, and is provided on the support surface 20 for regulating the position of the end surface of the roll paper 9 and the bottom of the roll paper holder 12 (not shown).

However, since the support surface 20 is inclined to the roll paper side with respect to the guide portion 21, its elasticity presses the end surface of the roll paper 9 and urges the roll paper to the opposite side. Will be.

FIG. 5 shows the platen roller 8 and the support pin 13.
It is explanatory drawing of the horizontal positional relationship of a and 13b. The central shaft 30 of the platen roller 8 and the support pins 13a and 13b
The straight line 31 connecting the centers of the two is on the same plane in the height direction, but makes a certain small angle θ in the horizontal direction as seen in FIG. That is, an angle θ is given to the feeding direction of the roll paper 9 supported by the support pins 13a and 13b with respect to the recording paper conveyance direction by the platen roller 8. By providing such an angle θ, a force is exerted on the roll paper 9 in the direction of arrow E during feeding, so that the position of the roll paper 9 in the thrust direction is stabilized and the recording paper conveyance position on the platen roller 8 is stabilized. Can be kept constant.

When the roll paper 9 is replaced, the support surface 20 of the partition plate 14 is deformed by a finger or the like in a direction away from the end face of the roll paper 9, so that the support pin is released from the roll paper 9 to remove the roll paper 9. It can be taken in and out from the roll paper holder 12.

When the support pin 13a is not directly provided on the side wall 12a of the roll paper holder 12 but the partition plate 14 is provided at a position close to the side wall 12a and the support pin 13b is used as the support pin 13a, the same operation is performed. The position of the support surface 20 of the partition plate 14 is regulated, for example, by providing a protrusion or the like on the side surface 12a for limiting escape (retraction) of the support surface 20.

The partition plate 14 as shown in FIGS. 3 and 4 is formed of an elastic material in order to urge the end surface of the roll paper 9 by utilizing the elasticity of the supporting surface 20 or 20a. However, the material is not limited to resin, and metal such as spring material may be used. Further, the partition plates 14 may be provided not only on one side of the roll paper 9 but on both sides to support the roll paper 9.

FIG. 6 is a schematic configuration diagram of a facsimile apparatus according to another embodiment of the present invention. In this embodiment, the roll paper 9
Is not held inside the apparatus, but the roll paper 9 is held outside the apparatus by the pair of holding arms 40. Therefore, it is not necessary to secure a space for storing the roll paper inside the apparatus, which facilitates downsizing of the apparatus. .

Each of the pair of holding arms 40 is detachably attached to the apparatus by fitting or screwing.
By changing the mounting position on one side, the distance between the holding arms can be changed to hold the roll paper 9 having different width sizes. Although not shown, each of the pair of holding arms 40 is provided with a holding pin similar to the holding pin 13 of the above-mentioned embodiment, and by inserting this into the end of the paper core of the roll paper 9, The paper 9 is rotatably held outside the apparatus. Further, since a slight difference is provided in the distance between the support pin provided on each of the pair of holding arms 40 and the platen roller 8, the distance between the support pin straight line and the axis of the platen roller 8 is as shown in FIG. Tilt angle θ as shown
Cause As a result, similarly to the first embodiment, the recording paper conveyance position in the thrust direction on the platen roller 8 can be kept constant.

Further, both of the pair of holding arms 40 are
The amount of protrusion from the device is variable, and by adjusting the amount of protrusion, roll paper with different diameters can be handled. When the roll paper 9 having a relatively small diameter is used, the holding arm 40
Need only be projected from the device by the required minimum length as shown in the figure, and the installation space of the device can be saved. On the other hand, by making the holding arm 40 project excessively as shown by the broken line 40a, it is possible to hold roll paper having a large diameter as shown by the broken line 9a.

FIG. 7 is a schematic configuration diagram of a facsimile apparatus according to another embodiment of the present invention. In this embodiment, the roll paper 9 can be held in a roll paper holder (roll paper accommodating space) 12 provided inside the device as shown in the drawing, or can be held outside the device as indicated by a broken line 9b.

The pair of holding arms 41 are the same as the holding arms 40 of the second embodiment, but are rotatable about a fulcrum F. The holding arm 41 can be rotated in the apparatus as shown in the figure, and the roll paper 9 can be rotatably held in the roll paper holder 12 by a pair of support pins provided therein. On the other hand, the holding arm 41 is broken line 4
By rotating the roll paper to the outside of the device as shown in 1b, the roll paper can be held to the outside of the device as shown by the broken line 9b. A locking mechanism utilizing elasticity of resin or the like is provided for rotating and fixing the holding arm 41 inside or outside the apparatus, but it is not shown. Further, the mounting position of at least one of the pair of holding arms 40 is variable, and roll papers having different width sizes can be held by changing the interval.

If the fulcrum F is brought closer to the outside of the device and the distance between the support pin and the outer wall of the device is increased when the holding arm 41 is rotated outside the device, roll paper with a small diameter is used. In this case, the holding arm 41 is rotated into the apparatus to accommodate the roll paper in the roll paper holder 12, and when using a roll paper having a large diameter that cannot be accommodated in the roll paper holder 12, the holding arm 41 is The roll paper can be held outside the device by rotating it outside the device.

FIG. 8 is a schematic block diagram of a facsimile apparatus according to another embodiment of the present invention. In this embodiment, two roll papers 9c and 9d are held inside and outside the apparatus at the same time and can be used. A pair of intermediate conveyance rollers 43 for the inner roll paper 9c and an outer roll paper 9d are used. And a pair of intermediate conveying rollers 44. The pair of holding arms 42 (similar to the holding arm 41 of the third embodiment) for holding the roll paper 9d outside the apparatus are removed from the apparatus when the roll paper is not held outside the apparatus, or It can be rotated and accommodated in the device. Although not shown, the roll paper holder 12 in the apparatus holds the roll paper by using a partition plate similar to that of the first embodiment.

As shown in FIG. 9, a straight line 32 connecting the centers of the support pins provided on the pair of holding arms 42 to the shaft center 30 of the platen roller 8 and the roll in the roll paper holder 12 are provided. Support pins (13) for supporting paper
The straight line 31 connecting the centers of a and 13b) forms minute angles θ1 and θ2 in opposite directions, respectively. When such a reverse inclination is set, the recording paper fed from the roll paper inside the apparatus and the recording paper fed from the roll paper outside the apparatus are displaced in the thrust position on the platen roller 8. As a result, when the sheet is discharged onto the recording paper tray (see FIG. 1), the position is displaced in the width direction. This means, for example, that the roll paper inside and outside the device is alternately used for each reception, or the roll paper inside the device is used for the first page of the received document and the roll paper outside the device is used for subsequent pages. This brings advantages such as sorting received documents.

It is also possible to use cut paper by manually inserting the recording paper into the intermediate conveying roller 44. Providing a cut sheet insertion guide facilitates such manual insertion of the cut sheet.
