　以下、本発明の実施の形態を図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　図１は、本発明の実施の形態に係る熱転写印画装置の概略構成図である。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、及び保護（ＯＰ）層が面順次に設けられた熱転写シート５を用いて、受像紙６（第１受像紙）上にＹ、Ｍ、Ｃを昇華転写させて画像を印画し、画像上に保護層を転写するサーマルヘッド１を備えている。熱転写シート５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。熱転写シート５及び受像紙６には、この種の熱転写印画装置で用いられる公知のものを使用することができる。 FIG. 1 is a schematic configuration diagram of a thermal transfer printing apparatus according to an embodiment of the present invention. The thermal transfer printing apparatus is a thermal transfer sheet 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 protective (OP) layer are sequentially provided. A thermal head 1 is provided which uses 5 to sublimate and transfer Y, M, and C onto the image receiving paper 6 (first image receiving paper) to print an image, and transfer a protective layer onto the image. In addition to the OP layer, the thermal transfer sheet 5 is provided with a melt layer containing a binder resin and a coloring material such as a pigment or 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. As the thermal transfer sheet 5 and the image receiving paper 6, known ones used in this type of thermal transfer printing apparatus can be used.
　熱転写シート５は巻出部３に巻き付けられており、巻出部３から巻き出された熱転写シート５は、サーマルヘッド１を通って、巻取部４に巻き取られて回収されるようになっている。 The thermal transfer sheet 5 is wound around the unwinding portion 3, and the thermal transfer sheet 5 unwound from the unwinding portion 3 passes through the thermal head 1 and is wound around the winding portion 4 and collected. ing.
　熱転写シート５を挟んでサーマルヘッド１と対向する位置にプラテンロール２が設けられている。サーマルヘッド１及びプラテンロール２を含む印画部１０は、受像紙６及び熱転写シート５を挟み込み、熱転写シート５を背面側から加熱して受像紙６の受容層に染料を転写することで画像を形成する。 A platen roll 2 is provided at a position facing the thermal head 1 with the thermal transfer sheet 5 interposed therebetween. The printing unit 10 including the thermal head 1 and the platen roll 2 sandwiches the image receiving paper 6 and the thermal transfer sheet 5, heats the thermal transfer sheet 5 from the back side, and transfers the dye to the receiving layer of the image receiving paper 6 to form an image. To do.
　受像紙６は、受像紙６を巻回した受像紙ロールＲから繰り出される。受像紙ロールＲは図示しない巻軸部品（ロール紙供給部）に取り付けられており、巻軸部品を回転（正転／逆転）させると、受像紙ロールＲが回転し、受像紙６の繰り出し（下流側への搬送）や巻取り（上流側への搬送）が行われる。 The image receiving paper 6 is unwound from the image receiving paper roll R around which the image receiving paper 6 is wound. The image receiving paper roll R is attached to a winding shaft component (roll paper supply unit) (not shown), and when the winding shaft component is rotated (forward / reverse rotation), the image receiving paper roll R rotates and the image receiving paper 6 is fed (rolled out). (Transport to the downstream side) and winding (transport to the upstream side) are performed.
　サーマルヘッド１の上流側、具体的にはサーマルヘッド１と受像紙ロールＲとの間に、受像紙６の搬送を行うための回転駆動自在なキャプスタンローラ７ａと、キャプスタンローラ７ａに受像紙６を圧着させるためのピンチローラ７ｂが設けられている。 A rotatable capstan roller 7a for transporting the image receiving paper 6 between the thermal head 1 and the image receiving paper roll R on the upstream side of the thermal head 1, and a capstan roller 7a on the image receiving paper. A pinch roller 7b for crimping 6 is provided.
　また、受像紙６の搬送路には、受像紙６を搬送するための駆動力のあるゴムローラである搬送ローラ４３と、搬送ローラ４３に受像紙６を圧着するための駆動力のないローラであるピンチローラ４４とが複数箇所に設けられている。 Further, in the transport path of the image receiving paper 6, there are a transport roller 43, which is a rubber roller having a driving force for transporting the image receiving paper 6, and a roller having no driving force for crimping the image receiving paper 6 to the transport roller 43. Pinch rollers 44 are provided at a plurality of locations.
　制御部Ｃは、熱転写印画装置の各部の駆動を制御し、印画処理を行う。印画処理では、まず、受像紙６と熱転写シート５のＹ層とが位置合わせされ、受像紙６及び熱転写シート５を介してサーマルヘッド１がプラテンロール２に当接する。次に、キャプスタンローラ７ａ及び巻取部４が回転駆動して、受像紙６及び熱転写シート５が上流側へ送られる。この間、画像データに基づいて、サーマルヘッド１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５から受像紙６上にＹが昇華転写される。 The control unit C controls the drive of each part of the thermal transfer printing device and performs the printing process. In the printing process, first, the image receiving paper 6 and the Y layer of the thermal transfer sheet 5 are aligned, and the thermal head 1 comes into contact with the platen roll 2 via the image receiving paper 6 and the thermal transfer sheet 5. Next, the capstan roller 7a and the take-up unit 4 are rotationally driven, and the image receiving paper 6 and the thermal transfer sheet 5 are sent to the upstream side. During this time, the region of the Y layer is selectively and sequentially heated by the thermal head 1 based on the image data, and Y is sublimated and transferred from the thermal transfer sheet 5 onto the image receiving paper 6.
　Ｙの昇華転写後、サーマルヘッド１が上昇し、プラテンロール２から離れる。次に、受像紙６と熱転写シート５のＭ層とが位置合わせされる。Ｙを昇華転写する方法と同様にして、受像紙６上にＭ及びＣが順次昇華転写され、受像紙６上に１画面分の画像が形成される。次に、サーマルヘッド１により画像上に保護層（ＯＰ層）が転写される。 After the sublimation transfer of Y, the thermal head 1 rises and separates from the platen roll 2. Next, the image receiving paper 6 and the M layer of the thermal transfer sheet 5 are aligned. Similar to the method of sublimation transfer of Y, M and C are sequentially sublimated and transferred onto the image receiving paper 6, and an image for one screen is formed on the image receiving paper 6. Next, the protective layer (OP layer) is transferred onto the image by the thermal head 1.
　保護層が転写された受像紙６は、下流側に設けられたカッタ８により所定サイズに切断され、印画物が作製される。印画物は、筐体２０の排紙口２２から排出される。 The image receiving paper 6 to which the protective layer is transferred is cut to a predetermined size by a cutter 8 provided on the downstream side to produce a photographic paper. The printed matter is discharged from the paper ejection port 22 of the housing 20.
　上述したように、受像紙６はロール状に巻回された受像紙ロールＲの状態で熱転写印画装置に装填されている。本実施形態では、受像紙ロールＲを筐体２０から取り出すことなく、受像紙６とは異なる種類の受像紙への印画処理を行うものである。 As described above, the image receiving paper 6 is loaded in the thermal transfer printing device in the state of the image receiving paper roll R wound in a roll shape. In the present embodiment, the printing process is performed on a different type of image receiving paper from the image receiving paper 6 without taking out the image receiving paper roll R from the housing 20.
　熱転写印画装置の筐体２０には、開口２４が設けられており、図２Ａに示すように、枚葉タイプの受像紙３２（第２受像紙）を収容したカセット３０が開口２４を介して脱着可能になっている。開口２４の位置は特に限定されない。受像紙３２は、受像紙６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。筐体２０には、カセット３０を取り外した際に開口２４を塞ぐための蓋が設けられていてもよい。 The housing 20 of the thermal transfer printing apparatus is provided with an opening 24, and as shown in FIG. 2A, a cassette 30 containing a sheet-fed type image receiving paper 32 (second image receiving paper) is attached and detached through the opening 24. It is possible. The position of the opening 24 is not particularly limited. Like the image receiving paper 6, the image receiving paper 32 is provided with a receiving layer for receiving the dye on one side thereof. The housing 20 may be provided with a lid for closing the opening 24 when the cassette 30 is removed.
　制御部Ｃは、カセット３０が筐体２０に取り付けられると自動的に、又は枚葉タイプの受像紙３２で印画処理を行うという指示をユーザから受け付けると、印画処理に使用する受像紙を、受像紙６から受像紙３２に切り替える。 When the control unit C receives an instruction from the user to automatically perform the printing process when the cassette 30 is attached to the housing 20 or to perform the printing process on the sheet-fed type image receiving paper 32, the control unit C receives the image receiving paper used for the printing process. Switch from paper 6 to image receiving paper 32.
　受像紙３２を用いた印画処理を開始するにあたり、制御部Ｃは、受像紙ロールＲを回転させ、印画処理中の受像紙３２と衝突しない位置まで、受像紙６を巻き取る。このとき、受像紙ロールＲは、受像紙６を用いた印画処理時よりも受像紙６を多く巻き取る。 When starting the printing process using the photographic paper 32, the control unit C rotates the photographic paper roll R and winds the photographic paper 6 to a position where it does not collide with the photographic paper 32 during the printing process. At this time, the image-receiving paper roll R winds up more image-receiving paper 6 than during the printing process using the image-receiving paper 6.
　搬送ローラ４０，４１によりカセット３０から繰り出された受像紙３２は、印画部１０より下流側、すなわち印画部１０と排紙口２２との間の搬送路に案内される。搬送ローラ４１に受像紙３２を圧着し、受像紙３２の重送給紙を防止する分離ローラ４２が設けられている。図２Ａでは、装置内の受像紙の搬送路を破線で示している。印画時の印画負荷に抗して受像紙の主搬送をキャプスタンローラ７ａが担う。複数の搬送ローラ４３及びピンチローラ４４が、印画時以外に受像紙３２を印画部１０まで搬送したり、印画後に受像紙３２を排紙口２２まで搬送したりする。 The image receiving paper 32 unwound from the cassette 30 by the transport rollers 40 and 41 is guided to the downstream side of the printing section 10, that is, the transport path between the printing section 10 and the paper ejection port 22. A separation roller 42 is provided by crimping the image receiving paper 32 to the transport roller 41 to prevent double feeding of the image receiving paper 32. In FIG. 2A, the transport path of the image receiving paper in the apparatus is shown by a broken line. The capstan roller 7a is responsible for the main transport of the image receiving paper against the printing load at the time of printing. The plurality of transport rollers 43 and pinch rollers 44 transport the image receiving paper 32 to the printing unit 10 other than at the time of printing, or convey the image receiving paper 32 to the paper ejection port 22 after printing.
　搬送路に導かれた受像紙３２には、受像紙６と同様の方法で、印画部１０により画像が形成される。印画部１０で画像が形成された受像紙３２は、排紙口２２から排出される。 An image is formed on the image receiving paper 32 guided to the transport path by the printing unit 10 in the same manner as the image receiving paper 6. The image receiving paper 32 on which the image is formed by the printing unit 10 is discharged from the paper ejection port 22.
　画像形成する受像紙を、枚葉タイプの受像紙３２からロールタイプの受像紙６に戻す場合は、カセット３０を取り外してもよいし、ユーザがロールタイプの受像紙６で印画処理を行うという指示を与えてもよい。 When returning the image-forming image-forming paper from the sheet-fed type image-receiving paper 32 to the roll-type image-receiving paper 6, the cassette 30 may be removed, or the user is instructed to perform printing processing on the roll-type image-receiving paper 6. May be given.
　このように本実施形態によれば、カセット３０を取り付けることで、印画に使用する受像紙を枚葉タイプの受像紙３２に変更できる。受像紙６を巻回した受像紙ロールＲを筐体２０から取り出す必要がないため、印画する受像紙の種類を簡便に変更できる。 As described above, according to the present embodiment, by attaching the cassette 30, the image receiving paper used for printing can be changed to the sheet-fed type image receiving paper 32. Since it is not necessary to take out the image receiving paper roll R around which the image receiving paper 6 is wound from the housing 20, the type of the image receiving paper to be printed can be easily changed.
　図２Ａに示す例では、積層されてカセット３０内に収容された受像紙３２を下から順に給紙する構成となっているが、図２Ｂに示すように上から順に給紙するようにしてもよい。 In the example shown in FIG. 2A, the image receiving papers 32 stacked and stored in the cassette 30 are fed in order from the bottom, but as shown in FIG. 2B, the image receiving papers 32 may be fed in order from the top. Good.
　図２Ａ、図２Ｂに示す例では、カセット３０から繰り出された受像紙３２が搬送路に進入する方向が、下流側の排紙口２２へ向かう方向となるようにカセット３０が取り付けられている。この場合、受像紙３２を一旦排紙口２２側へ送り、受像紙３２の全体が搬送路上にのると、上流側の印画部１０へ搬送する。図３に示すように、カセット３０から繰り出された受像紙３２が搬送路に進入する方向が、上流側の印画部１０へ向かう方向であってもよい。 In the examples shown in FIGS. 2A and 2B, the cassette 30 is attached so that the direction in which the image receiving paper 32 unwound from the cassette 30 enters the transport path is the direction toward the paper ejection port 22 on the downstream side. In this case, the image receiving paper 32 is once sent to the paper ejection port 22 side, and when the entire image receiving paper 32 is placed on the transport path, it is conveyed to the printing portion 10 on the upstream side. As shown in FIG. 3, the direction in which the image receiving paper 32 unwound from the cassette 30 enters the transport path may be the direction toward the printing portion 10 on the upstream side.
　枚葉タイプの受像紙３２を収容するカセット３０を複数取り付けられるようにしてもよい。図４は、２個のカセット３０が取り付けられる例を示す。複数のカセット３０を取り付けることで、使用（選択）可能な受像紙の種類を増やすことができる。ユーザから指示された受像紙（ユーザから指示されたカセットに収容された受像紙）が印画に使用される。 A plurality of cassettes 30 accommodating the sheet-fed type image receiving paper 32 may be attached. FIG. 4 shows an example in which two cassettes 30 are attached. By attaching a plurality of cassettes 30, the types of image receiving papers that can be used (selected) can be increased. The image receiving paper instructed by the user (the image receiving paper housed in the cassette instructed by the user) is used for printing.
　図５に示すように、カセット３０から繰り出された受像紙３２が、排紙口２２へ向かう方向で搬送路に進入する際に、受像紙３２の先端側の一部が排紙口２２から筐体２０の外へ出るようにしてもよい。すなわち、カセット３０から筐体２０内に取り込まれた受像紙３２の一部が、印画処理前に、筐体２０の外へ出るようにしてもよい。これにより、カセット３０から受像紙３２が繰り出され、画像形成する受像紙がロールタイプの受像紙６から枚葉タイプの受像紙３２に切り替わったことが確認できる。また、搬送ローラ４１から排紙口２２までの搬送路の長さを短くすることができ、筐体２０のサイズを小型化できる。 As shown in FIG. 5, when the image receiving paper 32 unwound from the cassette 30 enters the transport path in the direction toward the paper ejection port 22, a part of the tip end side of the image receiving paper 32 is molded from the paper ejection port 22. You may try to get out of the body 20. That is, a part of the image receiving paper 32 taken into the housing 20 from the cassette 30 may be taken out of the housing 20 before the printing process. As a result, it can be confirmed that the image receiving paper 32 is fed out from the cassette 30 and the image receiving paper forming the image is switched from the roll type image receiving paper 6 to the sheet-fed type image receiving paper 32. Further, the length of the transport path from the transport roller 41 to the paper ejection port 22 can be shortened, and the size of the housing 20 can be reduced.
　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。
