Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording method of a recording device for recording on recording paper cut into a predetermined size.

2. Description of the Related Art A thermal transfer recording apparatus, which is an example of a conventional recording apparatus of this type, has a configuration as shown in FIG. A description will be given below with reference to FIG. In the figure, 11 is a recording paper cut into a predetermined size. Reference numeral 12 denotes a drum, which is cylindrical and has an outer peripheral portion covered with a soft material such as rubber, and a cutout portion provided in a part of the outer peripheral portion. Here, the outer peripheral length of the drum 12 is
The total length of the recording paper 11 is made substantially equal. 13 is a paper holder, which engages with the notch on the outer periphery of the drum 12 and
The leading portion of the recording paper 11 is fixed by the urging force of 14. Reference numeral 15 denotes a paper guide for guiding the inserted recording paper 11 to the cutout portion of the drum 12 and for guiding the recording paper 11 wound around the drum 12 to the discharge port during the discharging operation. A pressing roller 16 presses the recording paper 11 to the outer circumference of the drum 12 when the recording paper 11 is wound around the outer circumference of the drum 12 by the rotation of the drum 12. Reference numeral 17 is an ink sheet having ink applied on a base film. The ink is black ink for monochrome recording, but for color recording, for example, yellow, magenta, and cyan inks are sequentially and repeatedly applied at regular intervals. 18 is a supply reel on which an unused ink sheet is wound. Reference numeral 19 is a take-up reel for taking up the used ink sheet. 20 is a thermal recording head, which is an ink sheet 17 and recording paper.
A large number of heat generating elements, which are pressed against the drum 12 via 11 and are arranged in the main scanning direction, are selectively energized to heat the elements, and the ink on the ink sheet 17 is transferred and recorded on the recording paper 11. . The operation of the conventional thermal transfer recording apparatus configured as described above will be described. The recording paper 11 is inserted along the paper guide 15 and the leading end of the recording paper 11 is the drum 12
When it comes to the notch part, this is detected by a detection means (not shown) and is fixed by the paper holder 13. Then, the drum 12 rotates in the direction of arrow A, and when the recording start position (point a in the figure) of the recording paper 11 reaches the position of the thermal recording head 20, the drum 12 is temporarily stopped and the recording start position of the ink sheet 17 is heated. The thermal recording head 20 is aligned with the position of the recording head 20, and then the thermal recording head 20 is pressed against the drum 12 via the ink sheet 17 and the recording paper 11 to press the drum 12.
The rotation of the recording head is restarted, and a recording signal is input to the thermal recording head 10 to generate heat and the recording operation is performed. When the recording progresses and the recording end position b of the recording paper 11 reaches the position of the thermal recording head 20, the drum 12 stops rotating and the thermal recording head 20 releases the pressure contact with the drum 12. In the case of monochrome recording, the recording is completed as described above, but in the case of color recording, the above-mentioned state is the stage when the recording of the first color (for example, yellow) is completed, and thus the second operation is performed with the same operation (for example, the second color). , Magenta) and the third color (for example, cyan) is recorded. When recording is completed, the drum 12 rotates in the direction of arrow B, the rear end of the recording paper 11 is peeled off from the drum 12 along the paper guide 15, and finally the paper holder 13 is moved to the top of the recording paper 11. The recording paper 11 is ejected after releasing the fixing of the section.

However, in such a recording method, the total length of the recording paper 11 and the outer peripheral length of the drum 12 are substantially equal to each other. It is very unreasonable from the viewpoint that the thermal recording head 20 is pressed and recorded in the entire length of 11, that is, the length between abs, and it is unreasonable to increase the diameter of the drum 12 to make it smaller and lighter. This is a serious problem in the device configuration in that the cueing operation and the like take a long time and the recording time becomes long due to the obstruction of the recording medium and the long margin.

Therefore, the present invention makes it possible to reduce the size and weight of the apparatus and shorten the recording time.

Means for Solving the Problems In order to solve the above problems, the present invention provides a rotating drum with a holder so that a part of the holder is exposed on the outer circumference of the drum, and the recording is cut into a predetermined size in the holder. Hold one end of the paper, wind this recording paper around the outer periphery of the drum, and wind the other end of the recording paper over the exposed part of the holder. A recording method is used in which recording is started on the recording paper from the vicinity of the end portion where one end is held and recording is started on the recording paper near the other end of the exposed portion of the holder. is there.

Operation The effect of this recording method is as follows. That is,
Hold one end of the recording paper cut into a predetermined size in the holder, wind this recording paper on the outer periphery of the drum and wind the other end of the recording paper on the exposed part of the holder,
The recording means starts recording on the recording paper from the vicinity of the end of the exposed part of the holder on the side that holds one end of the recording paper in the drum rotation direction, and the recording paper by the recording means near the other end of the exposed part of the holder. By ending the recording on the recording medium, the drum can be made smaller than the conventional one without reducing the ratio of the recording area to the recording paper, so that the apparatus can be made smaller and lighter. In addition, since the portion of the outer circumference that is not directly used for recording is shortened, the time for idle feeding of the drum and the cueing operation during color recording can be shortened, so the overall recording time can be shortened.

Embodiment Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings by taking a thermal transfer recording apparatus which is a kind of recording apparatus as an example. FIG. 1 is a schematic configuration diagram showing this embodiment. Reference numeral 1 is a recording paper cut into a predetermined size. Reference numeral 2 denotes a drum, which is cylindrical and has an outer peripheral portion covered with a soft material such as rubber, and a notch for fixing the leading portion of the recording paper 1 is provided in a part of the outer periphery. Here, the peripheral length of the outer peripheral portion of the drum 2 excluding the cutout portion is set to be substantially equal to the length (a to b) actually used for recording on the recording paper 1. Therefore, as shown in FIG.
Is a state in which the unrecorded margins of the leading end and the trailing end overlap with each other in the cutout portion of the drum 2 when wound around the drum, and as a result, the outer peripheral length of the drum 2 is the entire length of the recording paper 1. It's getting shorter. A paper holder 3 is engaged with a notch on the outer circumference of the drum 2 and is biased by a spring 4 to fix the leading portion of the recording paper 1. Reference numeral 5 denotes a paper guide for guiding the inserted recording paper 1 to the cutout portion of the drum 2, and for ejecting the recording paper 1 wound around the drum 2 to the ejection port. A pressing roller 6 presses the recording paper 1 to the outer circumference of the drum 2 when the recording paper 1 is wound around the outer circumference of the drum 2 by the rotation of the drum 2.
Reference numeral 7 is an ink sheet having ink applied on a base film. The ink is black ink for monochrome recording, but for color recording, for example, yellow, magenta, and cyan inks are sequentially and repeatedly applied at regular intervals. Reference numeral 8 denotes a supply reel, around which an unused ink sheet 7 is wound. Reference numeral 9 is a take-up reel for taking up the used ink sheet 7. A thermal recording head 10 is pressed against the drum 2 via the ink sheet 7 and the recording paper 1 and selectively energizes a large number of heating elements arranged in the main scanning direction to heat the heating elements. The ink on the ink sheet 7 is transferred and recorded on the recording paper 1.

The operation of the heat-sensitive transfer type recording apparatus of the present embodiment having the above-described structure will be described. When the recording paper 1 is inserted along the paper guide 5 and the leading portion of the recording paper 1 comes to the cutout portion of the drum 2, this is detected by a detection unit (not shown), and the leading portion of the recording paper 1 is detected by the paper holder 3. Fixed. After that, the drum 2 is rotated in the direction of arrow A, and is temporarily stopped when the recording start position a of the recording paper 1 reaches the position of the thermal recording head 10. Then, the recording start position of the ink sheet 7 is changed to the position of the thermal recording head 10. Then the thermal recording head
10 is pressed against the drum 2 via the ink sheet 7 and the recording paper 1 to restart the rotation of the drum 2 and at the same time, the thermal recording head.
A recording signal is input to 10 to selectively heat the heating element to perform the recording operation. When recording progresses and the recording end position b of the recording paper 1 reaches the position of the thermal recording head 10, the drum 2 stops rotating, the thermal recording head 10 stops recording, and the pressure contact with the drum 2 is released. In the case of monochrome recording, the recording is completed as described above, but in the case of color recording, since the recording of the first color (for example, yellow) is completed, the same operation is performed for the second color (for example, magenta) and 3 The color (for example, cyan) is recorded. In order to shift to the recording operation for the second and third colors, the recording paper 1 is conveyed by the rotation of the drum 2 in the A direction from the recording end position until the recording start position a reaches the position of the thermal recording head 10. It In this case, the moving distance of the drum 2 is shortened by the amount that the recording paper 1 is wound in the cutout portion of the drum 2 in an overlapping manner, and therefore the cueing operation time is shortened and the entire recording time is shortened. When recording is completed, the drum 2 rotates in the direction of arrow B, the rear end of the recording paper 1 is peeled off from the drum 2 along the paper guide 5, and finally the paper holder 3 is moved to the leading end of the recording paper 1. And the recording paper 1 is ejected.

As described above, according to this embodiment, by winding the recording paper 1 around the drum 2 so that the leading end and the trailing end of the recording paper 1 overlap with each other, the drum 2 can be downsized and the device can be downsized and lightened. The recording time can be shortened.

According to the present invention, a rotating drum is provided with a holder so that a part of the holder is exposed on the outer circumference of the drum, and the holder holds one end of recording paper cut into a predetermined size, and the holder is held on the outer circumference of the drum. The recording paper is wound around the holder, and the other end of the recording paper is wound on the exposed portion of the holder, and recording is performed from near the end of the exposed portion of the holder that holds one end of the recording paper in the drum rotation direction. The recording means starts recording on the recording paper and ends the recording on the recording paper by the recording means in the vicinity of the other end of the exposed portion of the holder, thereby reducing the diameter of the drum without reducing the ratio of the recording area to the recording paper. Since it is possible to reduce the size, it is possible to reduce the size and weight of the apparatus, and it is possible to shorten the paper transport operation time other than the recording operation, and therefore the recording time can be shortened as a whole.
Its industrial effect is enormous.
