FIG. 3 is a schematic cross-sectional view in the front-rear direction of the thermal transfer printing apparatus in which the cassette C1 is attached to the housing 1.
　受像紙ロールＲから繰り出された受像紙Ｐ１は、カセットＣ１の開口（図示略）、及び筐体１の開口１０を介して、筐体１内に取り込まれる。開口１０には、受像紙Ｐ１を筐体１内に取り込む取込ローラ１２が設けられている。筐体１内に取り込まれた受像紙Ｐ１は、搬送ローラ１４や、図示しないその他の搬送ローラにより搬送される。受像紙Ｐ１の一方の面には、染料を受容する受容層が設けられている。 The image receiving paper P1 unwound from the image receiving paper roll R is taken into the housing 1 through the opening (not shown) of the cassette C1 and the opening 10 of the housing 1. The opening 10 is provided with a take-in roller 12 for taking the image receiving paper P1 into the housing 1. The image receiving paper P1 taken into the housing 1 is conveyed by the transfer roller 14 and other transfer rollers (not shown). A receiving layer for receiving the dye is provided on one surface of the image receiving paper P1.
　熱転写印画装置は、イエロー染料（Ｙ）を含むＹ層、マゼンタ染料（Ｍ）を含むＭ層、シアン染料（Ｃ）を含むＣ層、及び表面保護（ＯＰ）層が面順次に設けられた熱転写シート２８を用いて、受像紙Ｐ１上にＹ、Ｍ、Ｃを昇華転写させて画像を印画し、画像上に保護層を形成するサーマルヘッド２１を備えている。熱転写シート２８には、ＯＰ層以外にも、バインダ樹脂と共に顔料やカーボンブラック等の色材を含む溶融層が、昇華転写用の染料層であるＹ層、Ｍ層及びＣ層と面順次に設けられていてもよい。 The thermal transfer printing apparatus is a thermal transfer in which a Y layer containing a yellow dye (Y), an M layer containing a magenta dye (M), a C layer containing a cyan dye (C), and a surface protection (OP) layer are sequentially provided. Using the sheet 28, a thermal head 21 is provided which sublimates and transfers Y, M, and C onto the image receiving paper P1 to print an image and forms a protective layer on the image. In addition to the OP layer, the thermal transfer sheet 28 is provided with a melt layer containing a binder resin and a coloring material such as pigment and carbon black in a surface-sequential manner with the Y layer, the M layer, and the C layer, which are dye layers for sublimation transfer. It may have been.
　熱転写シート２８は巻出部２４に巻き付けられており、巻出部２４から巻き出された熱転写シート２８は、サーマルヘッド２１を通って、巻取部２６に巻き取られて回収されるようになっている。 The thermal transfer sheet 28 is wound around the unwinding section 24, and the thermal transfer sheet 28 unwound from the unwinding section 24 is wound around the winding section 26 through the thermal head 21 and collected. ing.
　熱転写シート２８を挟んでサーマルヘッド２１と対向する位置にプラテンロール２２が設けられている。サーマルヘッド２１及びプラテンロール２２を含む印画部２０は、受像紙Ｐ１及び熱転写シート２８を挟み込み、熱転写シート２８を背面側から加熱して受像紙Ｐ１の受容層に染料を転写することで画像を形成する。その後、画像を保護するＯＰ層が熱転写シートから受容層上に転写される。 A platen roll 22 is provided at a position facing the thermal head 21 with the thermal transfer sheet 28 in between. The printing unit 20 including the thermal head 21 and the platen roll 22 sandwiches the image receiving paper P1 and the thermal transfer sheet 28, heats the thermal transfer sheet 28 from the back side, and transfers the dye to the receiving layer of the image receiving paper P1 to form an image. To do. The OP layer that protects the image is then transferred from the thermal transfer sheet onto the receiving layer.
　例えば、画像形成処理では、まず、受像紙Ｐ１と熱転写シート２８のＹ層とが位置合わせされ、受像紙Ｐ１及び熱転写シート２８を介してサーマルヘッド２１がプラテンロール２２に当接する。次に、搬送ローラ１４及び巻取部２６等が回転駆動して、受像紙Ｐ１及び熱転写シート２８が搬送される。受像紙Ｐ１はカセットＣ１側へ搬送され、一部がカセットＣ１に戻り、熱転写シート２８は巻取部２６に巻き取られる方向に搬送される。この間、画像データに基づいて、サーマルヘッド２１によりＹ層の領域が選択的に順次加熱され、熱転写シート２８から受像紙Ｐ１上にＹが昇華転写される。 For example, in the image forming process, first, the image receiving paper P1 and the Y layer of the thermal transfer sheet 28 are aligned, and the thermal head 21 comes into contact with the platen roll 22 via the image receiving paper P1 and the thermal transfer sheet 28. Next, the transport roller 14, the take-up portion 26, and the like are rotationally driven to transport the image receiving paper P1 and the thermal transfer sheet 28. The image receiving paper P1 is conveyed to the cassette C1 side, a part of the image receiving paper P1 returns to the cassette C1, and the thermal transfer sheet 28 is conveyed in the direction of being wound by the winding unit 26. During this time, the region of the Y layer is selectively and sequentially heated by the thermal head 21 based on the image data, and Y is sublimated and transferred from the thermal transfer sheet 28 onto the image receiving paper P1.
　Ｙの昇華転写後、サーマルヘッド２１が上昇し、プラテンロール２２から離れる。次に、受像紙Ｐ１と熱転写シート２８のＭ層とが位置合わせされる。この場合、受像紙Ｐ１は印画サイズに相当する距離だけ排出口１６側へ搬送され、熱転写シート２８はＹ層とＭ層との間のマージンに相当する距離だけ巻取部２６に巻き取られる方向に搬送される。Ｙを昇華転写する方法と同様にして、受像紙Ｐ１上にＭが昇華転写される。次に、同様の方法でＣが昇華転写される。受像紙Ｐ１にＹ、Ｍ、Ｃを重ねて印画することで、画像が形成される。続いて、画像上にＯＰ層が転写される。 After the sublimation transfer of Y, the thermal head 21 rises and separates from the platen roll 22. Next, the image receiving paper P1 and the M layer of the thermal transfer sheet 28 are aligned. In this case, the image receiving paper P1 is conveyed to the discharge port 16 side by a distance corresponding to the printing size, and the thermal transfer sheet 28 is wound around the winding unit 26 by a distance corresponding to a margin between the Y layer and the M layer. Will be transported to. M is sublimated and transferred onto the image receiving paper P1 in the same manner as in the method of sublimating and transferring Y. Next, C is sublimated and transferred in the same manner. An image is formed by superimposing Y, M, and C on the image receiving paper P1 and printing. Subsequently, the OP layer is transferred onto the image.
　このように、Ｙ、Ｍ、Ｃの昇華転写及びＯＰ層の転写の各転写処理に合わせて、受像紙Ｐ１は筐体１内を前後に移動する。上述の例では、熱転写シート２８を加熱する際に、受像紙Ｐ１がカセットＣ１に戻る方向に搬送され、熱転写シート２８が巻取部２６に巻き取られる方向に搬送されるとしたが、搬送方向は逆方向であってもよい。 In this way, the image receiving paper P1 moves back and forth in the housing 1 in accordance with each transfer process of the sublimation transfer of Y, M, and C and the transfer of the OP layer. In the above example, when the thermal transfer sheet 28 is heated, the image receiving paper P1 is conveyed in the direction of returning to the cassette C1, and the thermal transfer sheet 28 is conveyed in the direction of being wound by the winding unit 26. May be in the opposite direction.
　熱転写シート２８のＹ層、Ｍ層、Ｃ層には、バインダ樹脂に、昇華性染料を溶融又は分散させた材料を用いることが好ましい。ＯＰ層には、透明で、耐擦過性、耐光性等を有する材料を用いることが好ましい。 For the Y layer, M layer, and C layer of the thermal transfer sheet 28, it is preferable to use a material in which a sublimation dye is melted or dispersed in a binder resin. For the OP layer, it is preferable to use a transparent material having scratch resistance, light resistance and the like.
　画像が形成された受像紙Ｐ１は、筐体１の正面１ｆ側へ搬送され、カッタ３０により所定サイズに切り出された印画物が排出口１６から排出される。 The image receiving paper P1 on which the image is formed is conveyed to the front 1f side of the housing 1, and the photographic paper cut out to a predetermined size by the cutter 30 is discharged from the discharge port 16.
　図４Ａ、図４Ｂは、枚葉紙タイプの受像紙Ｐ２（図５参照）を収容するカセットＣ２（第２カセット）を筐体１に取り付けた状態の斜視図である。図５は、筐体１にカセットＣ２を取り付けた熱転写印画装置の前後方向の概略断面図である。 4A and 4B are perspective views in a state where the cassette C2 (second cassette) accommodating the sheet-fed paper type image receiving paper P2 (see FIG. 5) is attached to the housing 1. FIG. 5 is a schematic cross-sectional view in the front-rear direction of the thermal transfer printing apparatus in which the cassette C2 is attached to the housing 1.
　カセットＣ２は筐体１に取り付けた状態で斜め後方に立ち上がっており、複数の受像紙Ｐ２を積層して収容している。受像紙Ｐ２は、受像紙Ｐ１と同様に、一方の面に染料を受容する受容層が設けられたものである。 The cassette C2 stands diagonally rearward while being attached to the housing 1, and accommodates a plurality of image receiving papers P2 in a laminated manner. Similar to the image receiving paper P1, the image receiving paper P2 is provided with a receiving layer for receiving the dye on one side thereof.
　受像紙Ｐ２は、カセットＣ２の開口（図示略）、及び筐体１の開口１０を介して、筐体１内に１枚ずつ取り込まれる。取込ローラ１２によって筐体１内に取り込まれた受像紙Ｐ２は、搬送ローラ１４や、図示しないその他の搬送ローラにより搬送され、印画部２０で画像が形成され、排出口１６から排出される。受像紙Ｐ２への画像形成及び保護層転写の処理は、上述した受像紙Ｐ１への処理と同様である。 The image receiving paper P2 is taken into the housing 1 one by one through the opening of the cassette C2 (not shown) and the opening 10 of the housing 1. The image receiving paper P2 taken into the housing 1 by the taking-in roller 12 is conveyed by the conveying roller 14 and other conveying rollers (not shown), an image is formed by the printing unit 20, and the image is discharged from the ejection port 16. The processing of image formation on the image receiving paper P2 and the transfer of the protective layer is the same as the processing on the image receiving paper P1 described above.
　カセットＣ１から繰り出される受像紙Ｐ１と、カセットＣ２から繰り出される受像紙Ｐ２とは、開口１０を介して取込ローラ１２によって筐体１内に取り込まれ、開口１０から排出口１６までの搬送路が同じである。受像紙を筐体１内に取り込むための開口１０及び取込ローラ１２は、カセットＣ１を取り付けてロール紙タイプの受像紙を使用する場合とカセットＣ２を取り付けて枚葉紙タイプの受像紙を使用する場合とで共通である。また、印画部２０で画像が形成され、カッタ３０で受像紙Ｐ１から切り出された印画物、及び印画部２０で画像が形成された受像紙Ｐ２である印画物は共に排出口１６から排出される。 The image receiving paper P1 unwound from the cassette C1 and the image receiving paper P2 unwound from the cassette C2 are taken into the housing 1 by the take-in roller 12 through the opening 10, and the transport path from the opening 10 to the discharge port 16 is provided. It is the same. The opening 10 and the take-in roller 12 for taking in the image receiving paper into the housing 1 use a roll paper type receiving paper with the cassette C1 attached and a sheet paper type receiving paper with the cassette C2 attached. It is common to the case of doing. Further, both the photographic paper in which the image is formed by the printing unit 20 and cut out from the image receiving paper P1 by the cutter 30 and the photographic paper P2 in which the image is formed by the printing unit 20 are discharged from the discharge port 16. ..
　制御部４０は、取り付けられたカセットが、受像紙ロールＲを収容するカセットＣ１であるか、又は枚葉紙タイプの受像紙Ｐ２を収容するカセットＣ２であるかを判別し、熱転写印画装置の各部の動作を制御する。 The control unit 40 determines whether the attached cassette is the cassette C1 accommodating the image receiving paper roll R or the cassette C2 accommodating the sheet-fed paper type image receiving paper P2, and each part of the thermal transfer printing apparatus. Control the operation of.
　カセットの判別方法は特に限定されない。例えば、カセットＣ１，Ｃ２にそれぞれ異なる形状の凸部（突起）が設けられているか、又は異なる位置に凸部が設けられている。カセットＣ１又はＣ２を筐体１に取り付けた際の凸部の係合の違いにより、制御部４０は取り付けられたカセットを特定する。 The method of identifying the cassette is not particularly limited. For example, the cassettes C1 and C2 are provided with convex portions (projections) having different shapes, or the convex portions are provided at different positions. The control unit 40 identifies the attached cassette by the difference in engagement of the convex portions when the cassettes C1 or C2 are attached to the housing 1.
　カセットＣ１，Ｃ２にそれぞれカセット情報を含む信号を送信可能な電気回路を設け、筐体１にカセットＣ１，Ｃ２を取り付けると、電気回路が制御部４０へ信号を送信するようにしてもよい。制御部４０は、カセットの電気回路から受信した信号に基づいて、取り付けられたカセットを特定する。信号を送信する電気回路は、ＩＣタグであってもよい。 If an electric circuit capable of transmitting a signal including cassette information is provided in each of the cassettes C1 and C2 and the cassettes C1 and C2 are attached to the housing 1, the electric circuit may transmit the signal to the control unit 40. The control unit 40 identifies the mounted cassette based on the signal received from the electric circuit of the cassette. The electric circuit that transmits the signal may be an IC tag.
　あるいはまた、熱転写印画装置の操作盤（図示略）をユーザが操作し、取り付けたカセットの種類を入力するようにしてもよい。 Alternatively, the user may operate the operation panel (not shown) of the thermal transfer printing device and input the type of the attached cassette.
　このように本実施形態によれば、カセットを付け替えるという簡易な作業で、ロール紙タイプの受像紙と枚葉紙タイプの受像紙の両方が使用可能となるため、１台の熱転写印画装置で様々なユーザに対応できる。また、受像紙の取り込み用の開口１０、印画物の排出口１６、筐体１内での受像紙の搬送路を、ロール紙タイプの受像紙と枚葉紙タイプの受像紙とで共通にしているため、熱転写印画装置のサイズやコストを抑えることができる。 As described above, according to the present embodiment, both roll paper type image receiving paper and sheet paper type image receiving paper can be used by a simple operation of replacing the cassette, so that one thermal transfer printing device can be used for various purposes. It can correspond to various users. Further, the opening 10 for taking in the photographic paper, the discharge port 16 for the photographic paper, and the transport path for the photographic paper in the housing 1 are made common to the roll paper type image receiving paper and the sheet paper type receiving paper. Therefore, the size and cost of the thermal transfer printing apparatus can be reduced.
　ロール紙タイプの受像紙Ｐ１及び枚葉紙タイプの受像紙Ｐ２は、それぞれカセットＣ１、Ｃ２に収容された状態で筐体１に取り付けられる。受像紙Ｐ１，Ｐ２は、画像形成や保護層転写の処理の際に、筐体１内を前後に移動し、開口１０を介して筐体１の外に出る場合もあるが、カセットＣ１、Ｃ２の内部にあるため、ゴミ等が付着することを抑制できる。 The roll paper type image receiving paper P1 and the sheet paper type image receiving paper P2 are attached to the housing 1 in a state of being housed in the cassettes C1 and C2, respectively. The image receiving papers P1 and P2 may move back and forth inside the housing 1 and go out of the housing 1 through the opening 10 during image formation and protective layer transfer processing, but cassettes C1 and C2 Since it is inside the building, it is possible to prevent dust from adhering to it.
　また、開口１０を介して筐体１の外に出た受像紙Ｐ１、Ｐ２はカセットＣ１、Ｃ２によって支持されているため、姿勢が安定しており、取込ローラ１２や搬送ローラ１４等が受像紙Ｐ１、Ｐ２を挟み込み易く、受像紙Ｐ１、Ｐ２の搬送による位置ズレを抑制できる。そのため、受像紙Ｐ１、Ｐ２にＹ、Ｍ、Ｃを重ねて印画する際に印画位置のズレを抑制し、高精細な画像を形成できる。 Further, since the image receiving papers P1 and P2 that have come out of the housing 1 through the opening 10 are supported by the cassettes C1 and C2, the posture is stable, and the taking-in roller 12, the conveying roller 14, and the like receive the image. It is easy to sandwich the papers P1 and P2, and the positional deviation due to the transport of the image receiving papers P1 and P2 can be suppressed. Therefore, when Y, M, and C are superimposed on the image receiving papers P1 and P2 to print, the deviation of the printing position can be suppressed and a high-definition image can be formed.
　上記実施形態では、ロール紙タイプの受像紙を収容するカセットと枚葉紙タイプの受像紙を収容するカセットのいずれか一方のみが取り付けられる構成について説明したが、両方のカセットが同時に取り付けられるようにしてもよい。 In the above embodiment, the configuration in which only one of the cassette containing the roll paper type receiving paper and the cassette containing the sheet paper type receiving paper is attached has been described, but both cassettes can be attached at the same time. You may.
　例えば、図６、図７に示すように、筐体１の正面１ｆに、枚葉紙タイプの受像紙Ｐ２を収容するカセットＣ３を装填するための開口１８をさらに設ける。開口１８にバネで付勢されたフラップ状の蓋を設け、カセットＣ３が装填されていない時は開口１８を塞ぎ、埃などが筐体１内に入らないようにしてもよい。 For example, as shown in FIGS. 6 and 7, an opening 18 for loading a cassette C3 for accommodating a sheet-sheet type image receiving paper P2 is further provided on the front surface 1f of the housing 1. A flap-shaped lid urged by a spring may be provided in the opening 18 to close the opening 18 when the cassette C3 is not loaded so that dust or the like does not enter the housing 1.
　カセットＣ３から繰り出された受像紙Ｐ２は、搬送ローラ１５等により筐体１内を搬送し、印画部２０で画像が形成され、排出口１６から排出される。 The image receiving paper P2 drawn out from the cassette C3 is conveyed in the housing 1 by a conveying roller 15 or the like, an image is formed by the printing unit 20, and is discharged from the ejection port 16.
　これにより、例えば、ロール紙タイプの受像紙を主に使用するユーザは、カセットＣ１を筐体１に取り付けたまま、枚葉紙タイプの受像紙を使用することができる。 Thereby, for example, a user who mainly uses a roll paper type image receiving paper can use a sheet paper type image receiving paper while the cassette C1 is attached to the housing 1.
　本発明を特定の態様を用いて詳細に説明したが、本発明の意図と範囲を離れることなく様々な変更が可能であることは当業者に明らかである。
　本出願は、２０１９年８月２６日付で出願された日本特許出願２０１９－１５３９４３に基づいており、その全体が引用により援用される。 Although the present invention has been described in detail using specific embodiments, it will be apparent to those skilled in the art that various modifications can be made without departing from the intent and scope of the invention.
