を生じる結果となる。Problems to be Solved by the Invention In general, in order to obtain high-quality color recording, it is necessary to superimpose three to four colors with high precision. If this superimposition is misaligned, so-called color misregistration occurs, resulting in unnatural color outlines and a decrease in image resolution. However, if the reduction ratio between each component in the reduction drive transmission mechanism that transmits the rotational force of the platen roller of such an apparatus from the drive means is set arbitrarily, the The relative positional relationship between the components at any given time may be different. In this case, the influence of the rotational unevenness characteristics of each component on the rotational unevenness of the platen roller differs for each color, resulting in color misregistration.

減少せしめるものである。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention reduces the reduction ratio between each component in the reduction drive transmission mechanism to an integer fraction, thereby reducing the speed at any point during one rotation of the platen roller. This is to make the relative positional relationship of each component the same, thereby reducing color misregistration.

ラー記録を得ることができる。Function The present invention has the above configuration, that is, the reduction ratio between each component in the reduction drive transmission mechanism is reduced to 1/integer, and 1
The relative positional relationship between each component at any point in time during color recording is determined between each color, and the characteristics of platen roller rotational unevenness caused by rotational unevenness specific to each component can be evaluated using the same characteristics for each color. As a result, it is possible to reduce color misregistration during color overlapping recording, and it is also possible to obtain high-quality color recording.

ゼンタの一画面ぶんの記録をおこなう。Next, the operation of the apparatus of this embodiment will be explained in Figs. 1, 2, and 3.
This will be explained using FIG. First, during the image-receiving paper loading operation, the thermal head 7, guide roller 8,
9 is placed away from the drum 3, and the image receiving paper 1 is placed in the paper holder 2.
When the paper is at a position directly above the drum 3, it is conveyed in the direction of arrow a, and the paper holder 2 descends as shown by 2a, and the leading end is clamped. The motor 11 then drives the drive gear 12 and the intermediate gear 13.
The drum gear 1o is rotated through the angle 14, and the drum 3 is rotated in the direction of the arrow until the sensor 16 detects the notch 10a. At this time, the recording start portion of the first color yellow ink has come to the position facing the heating element 7a of the ink sheet 4, and the thermal head 7 and guide rollers 8, 9
moves in the direction of arrow C and heats the heating element 7 of the thermal head 7.
The portion a is pressed against the drum 3 via the ink sheet 4 and the image receiving paper 1. This state is shown in FIG. 1 as the recording start state. Next, when the motor 11 is driven to rotate the drum 3 in the direction of the arrow d, the image receiving paper 1 and the ink sheet 4 are also conveyed in the direction of the arrow d while remaining in close contact with each other due to friction, and at the same time a yellow image signal is sent to the thermal head 7. The ink is transmitted in synchronization with the transport speed of the image-receiving paper 1, and the heating elements 7a are sequentially and selectively heated to transfer the ink onto the image-receiving paper 1 to obtain a desired yellow image. At this time, the sheet supply reel 6
is rotated in the direction of arrow f while applying an appropriate pack tensile strength, and the sheet take-up reel 6 is rotated in the direction of arrow q to wind up the ink sheet 4. As soon as the image signal for one screen of yellow has been transmitted through the above operations, the drum 3
The thermal head 7 and guide rollers 8 and 9
is separated from drum 3. This state is shown in FIG. 4 as a recording end state. Thereafter, the drum 3 is rotated in the direction of the arrow, and when the sensor 15 detects the notch 10a again, the rotation of the drum 3 is stopped. At this time, the ink sheet 4 is conveyed for a certain period of time in the direction of arrow i by the sheet take-up reel 6, and a second
The area where magenta ink begins to be recorded comes. After the above operations in FIG. It is pressed into contact with the drum 3 via the drum 3. In this way, the drum 3 is rotated, and one screen of magenta is recorded superimposed on the previously recorded yellow image.
その後同様にしてシアンの画像を重ねて記録し、カラー
記録を完了する。Thereafter, a cyan image is recorded overlappingly in the same manner to complete color recording.

少する。Here, if at least one of the driving gear 12, the intermediate gear 13, 14, and the drum gear 10 has uneven tooth pitch or eccentricity of the pitch circle, the motor 1
Even if the rotational accuracy of the drum 1 is good, rotational unevenness occurs in the drum 3, resulting in unevenness in the pitch of the image recorded on the image receiving paper 1. However, in the gear configuration of this embodiment, the intermediate gears 14 and 13 rotate twice while the drum gear 1o rotates once.
The drive gear 12 rotates three times while the intermediate gear 13 rotates once. The rotational characteristics of the drum 3 due to the tooth pitch unevenness of each gear and the eccentricity of the pitch circle appear periodically every rotation of each gear, so the meshing state of the teeth of each gear while recording one color is , is also reproduced during recording of the other two colors, thereby making the pitch unevenness of the recorded image uniform between each color and reducing color shift.

ある。FIG. 6 is a basic configuration diagram of a color recording apparatus showing a second embodiment of the present invention. In the figure, 1 is an image receiving paper, 2 is a paper holder, 3 is a drum, 4 is an ink sheet, 6 is a sheet supply reel, 6 is a sheet winding reel, 7 is a thermal head,
8 r 9 is a guide roller, 11 is a motor, and 16 is a sensor, which is the same as the configuration shown in FIG. 1. 1st
The difference from the configuration shown in the figure is that a timing belt is used for the deceleration drive transmission mechanism; 16.17 is a timing belt, 1
A drum pulley 8 has a drum shaft 3a fixed thereto so as to rotate integrally with the drum 3, and has a notch 18a for detecting the position of the drum 3 at the start of recording.
2o is a drive pulley fixed to the motor shaft 11a, 2o is an intermediate pulley connected to the drive pulley 19 by a timing belt 16, and 21 is an intermediate pulley that rotates integrally with the intermediate pulley 20 and is connected to a drum pulley 18 by a timing belt 17. It's a pulley. These timing belts 16, 17, drive pulley 19, intermediate pulleys 20, 21, and drum pulley 18 constitute a deceleration drive transmission mechanism 5, and the pulley pitch diameter is, for example, 30 mm for the drive pulley 19 and 30 mm for the intermediate pulley 2o.
is 90 mm, the intermediate pulley 21 is 36 mm, and the drum pulley 18 is 72 mm, and the reduction ratios are % and %, respectively, and the final reduction ratio is %. The configuration of the drum position detection sensor is the same as that shown in FIG. 2, except that the drum gear 1o and notch 10a are replaced by a drum pulley 18 and a notch 18a.

チむらを各々同一にし色ずれが減少する。The second embodiment configured as described above performs the same operation as the first embodiment to complete color recording, so the explanation will be omitted. Here, if the drive pulley 19 and the intermediate pulley 2
If tooth pitch unevenness or pitch circle eccentricity exists in at least one of the drum pulleys 18 and 18, rotational unevenness will occur in the drum 3, which will appear as pitch unevenness in the image. However, in the gear configuration of this embodiment, while the drum pulley 18 rotates once, the intermediate pulley 20.
21 rotates twice, and while the intermediate pulley 2o rotates once, the drive pulley 19 rotates three times. The rotational characteristics of the drum 3 due to uneven tooth pitch of each pulley or eccentricity of the pitch circle are as follows:
Since each pulley rotates periodically, the relative positional relationship of each pulley while recording one color is different from that of the other two.
This is also reproduced during color recording, thereby making the pitch unevenness of each recorded image the same and reducing color shift.
なお、第１の実施例において駆動歯車１２の歯数を３０

であれば、各プーリのピッチ径はいくらでもよいことは
言うまでもない。In addition, in the first embodiment, the number of teeth of the drive gear 12 is 30.
The number of teeth of the intermediate gears 13 and 14 is 9o and 36, respectively, and the number of teeth of the drum gear 10 is 72. However, any value may be used as long as the reduction ratio between the meshing gears is 1/an integer. Similarly, in the second embodiment, as long as the reduction ratio between the pulleys connected by the timing belt is an integer of 17, it goes without saying that the pitch diameter of each pulley may be any value.
また、両実施例において、サーマルヘッド７はライン型

きる。Further, in both embodiments, a line-type thermal head 7 was used, but a serial-type thermal head 7 may also be used.Although the ink transfer method used is melting, sublimation transfer may also be used. Furthermore, although the order of printing colors is yellow, magenta, and cyan, the same effect can be obtained even if the colors are printed in a different order.

果を得ることができる。In addition, the same effect can be obtained by marking a part of the ink sheet 4 and controlling it with a sensor so that the recording start portion of each color or the first color stops at a position facing the heating element 7a. However, the same effect can be obtained even if the deceleration drive transmission mechanism of the present invention is adopted in a color recording apparatus that uses a method of increasing the density by performing single-color recording a plurality of times.
さらに記録手段として熱転写記録以外の方法を用いても
同様の効果を得ることができる。Furthermore, the same effect can be obtained even if a method other than thermal transfer recording is used as the recording means.
