The printed transfer sheet 5 is discharged from the secondary transfer portion B at the discharge portion D, and the ink ribbon 1 and the transfer film 2 that have finished printing the image are respectively transferred to the cylindrical winding cores 21 and 22 ( Winded up (via outfeed roll).

上記熱転写プリンタは、図８（ａ）の正面図に示すように、ウエブロール状のインクリボン１と転写フィルム２とを巻回する筒状の巻き出しコア１１、１２（及び巻き取りコア２１、２２）の筒状の両端部を回転可能に支持するスラスト方向に対向する一対（又はスラスト方向に１本）の駆動回転軸３１と、該回転軸３１の両端部に対向する一対の盤状の鍔部３２と、その一対の盤状の鍔部３２のうち他端部の鍔部３２を一端部の鍔部３２方向（矢印方向）に弾力的に付勢する付勢部と、コアの一端部（又は両端部）側の鍔部３２の鍔面から突出しているコア嵌合凸部３３とを備えている。   As shown in the front view of FIG. 8A, the thermal transfer printer includes cylindrical unwinding cores 11 and 12 (and a winding core 21) for winding a web roll-shaped ink ribbon 1 and a transfer film 2. 22) a pair of driving rotating shafts 31 (or one in the thrust direction) opposed to the thrust direction for rotatably supporting both ends of the cylindrical shape, and a pair of disk-shaped facing the both ends of the rotating shaft 31. A flange 32, a biasing portion that elastically biases the flange 32 at the other end of the pair of disk-shaped flanges 32 in the direction of the flange 32 (arrow direction) at one end, and one end of the core The core fitting convex part 33 which protrudes from the collar surface of the collar part 32 of the part (or both ends) side is provided.

前記巻き出しコア１１、１２（及び巻き取りコア２１、２２）の筒状の一端部には、コア嵌合凸部３３に嵌合（係合）して、コアの空転を防止するための嵌合凹部１１ａ、１２ａ（及び嵌合凹部２１ａ、２２ａ）を備えている。   The cylindrical cores of the unwinding cores 11 and 12 (and the winding cores 21 and 22) are fitted (engaged) with the core fitting convex portion 33 to prevent the core from slipping. Joint recesses 11a and 12a (and fitting recesses 21a and 22a) are provided.

上記熱転写プリンタにコアを装着（セット）する際には、図８（ａ）に示すように、インクリボン１と転写フィルム２のそれぞれ巻き出しコア１１、１２（及び巻き取りコア２１、２２）のそれぞれ両端部の筒状内に、熱転写プリンタの（対向する一対の）駆動回転軸３１を嵌装してコアを支持した後に、コアの他端部を、駆動回転軸３１の付勢部付きの鍔部３２にて一端部の鍔部３２の方向に押圧すると共に、コアの嵌合凹部１１ａ、１２ａ（及び嵌合凹部２１ａ、２２ａ）を、前記駆動回転軸３１のコア嵌合凸部３３に回転位相位置を整合させ、図８（ｂ）に示すように、コアの嵌合凹部とコア嵌合凸部を嵌合（係合）して装着し、コアを駆動回転軸３１に対して空転しないようにして回転させるものである。   When the core is mounted (set) on the thermal transfer printer, as shown in FIG. 8A, the unwinding cores 11 and 12 (and the winding cores 21 and 22) of the ink ribbon 1 and the transfer film 2, respectively. Each of the cylindrical ends at both ends is fitted with a pair of opposing drive rotation shafts 31 of the thermal transfer printer to support the core, and then the other end of the core is attached with a biasing portion of the drive rotation shaft 31. While pressing the flange 32 toward the flange 32 at one end, the core fitting recesses 11 a and 12 a (and the fitting recesses 21 a and 22 a) are formed on the core fitting protrusion 33 of the drive rotating shaft 31. As shown in FIG. 8 (b), the rotational phase position is aligned, and the core fitting concave portion and the core fitting convex portion are fitted (engaged) and mounted, and the core is idled with respect to the drive rotating shaft 31. It is made to rotate without doing.

しかしながら、熱転写プリンタの駆動回転軸３１にコアをセットする際に、図８（ｂ）に示すように、コアの嵌合凹部とコア嵌合凸部とを確実に噛み合わせる必要があり、図８（ｃ）に示すように、コアの嵌合凹部と回転軸のコア嵌合凸部とが噛み合っていない状態で、回転軸３１を駆動回転させると、コアが回転軸３１に対して正常な位置にセットされないので、その結果、コアは正常な回転が行われず、巻回されているフィルムの斜行、フィルムの巻きズレ、フィルムのエッジの損傷、熱転写プリンタ装置本体への影響などの不具合が発生する可能性がある。   However, when the core is set on the drive rotation shaft 31 of the thermal transfer printer, as shown in FIG. 8B, it is necessary to securely mesh the core fitting concave portion with the core fitting convex portion. As shown in (c), when the rotary shaft 31 is driven and rotated in a state where the core fitting concave portion of the core and the core fitting convex portion of the rotary shaft are not engaged with each other, the core is in a normal position with respect to the rotary shaft 31. As a result, the core does not rotate normally, causing problems such as skewing of the film being wound, film winding misalignment, film edge damage, and effects on the thermal transfer printer main body. there's a possibility that.

そこで、熱転写プリンタの駆動回転軸にコアをセットする際に、確実にコアを駆動回転軸にセットできるように、駆動回転軸に対するコアの着脱を何回か繰り返して、その凹凸が噛み合うように、気を使って慎重にセットしなければならない。そのために時間と労力を要していた。   Therefore, when setting the core on the drive rotation shaft of the thermal transfer printer, in order to ensure that the core can be set on the drive rotation shaft, the attachment and detachment of the core to and from the drive rotation shaft is repeated several times so that the unevenness is engaged. You must be careful and set carefully. This required time and effort.

A film unwinding and winding core mounting device for a thermal transfer printer according to claim 4 or 5, which is one or both of a winding core and a winding core.

本発明の熱転写プリンタのフィルム巻出し巻取り方法方法、及び熱転写プリンタのフィルム巻出し巻取り巻回コア装着装置によれば、駆動回転軸の一対の対向する鍔部（の一方又は両方）に設けたコア嵌合凸部は、対向する鍔部の方向にバネにより付勢されているので、回転位相位置を整合させた巻回コアの両端部の端面（一端面又は両端面）に形成されたコア嵌合凹部内に、バネの付勢力により押し込まれて、凹凸嵌合し易くなり、巻回コアを熱転写プリンタの駆動回転軸にセットし易くなる。   According to the film unwinding and winding method method of the thermal transfer printer and the film unwinding / winding winding core mounting device of the thermal transfer printer according to the present invention, the film is provided on a pair (one or both) of the opposite facing flanges of the drive rotating shaft. Since the core fitting convex part is urged by the spring in the direction of the opposite collar part, it is formed on the end faces (one end face or both end faces) of both ends of the wound core whose rotational phase positions are aligned. It is pushed into the core fitting recess by the urging force of the spring, so that the concave and convex portions are easily fitted, and the winding core is easily set on the drive rotation shaft of the thermal transfer printer.

また、巻回コアの嵌合凹部と駆動回転軸の嵌合凸部の回転位相位置が、互いに整合していない状態、あるいは互いに嵌合前に干渉する位置にある状態において、駆動回転軸に巻回コアを支持したとしても、駆動回転軸の嵌合凸部はバネ力により巻回コアの端面を押し戻そうとする付勢力が働いているので、巻回コア又は駆動回転軸のいずれか一方を、僅かに回転させ、互いに整合する位相位置（正規位置）まで移動させることにより、凹凸嵌合が可能になる。   In addition, when the rotational phase positions of the fitting concave portion of the winding core and the fitting convex portion of the drive rotating shaft are not aligned with each other or are in a position where they interfere with each other before fitting, the winding is wound around the driving rotating shaft. Even if the winding core is supported, the urging force that pushes back the end surface of the winding core by the spring force acts on the fitting convex part of the driving rotary shaft, so either the winding core or the driving rotary shaft Are slightly rotated and moved to phase positions (regular positions) that are aligned with each other, thereby making it possible to fit the concave and convex portions.

また、巻回コアの嵌合凹部と駆動回転軸の嵌合凸部の回転位相位置が、互いに整合して
いない状態、あるいは互いに嵌合前に干渉する位置にある状態において、駆動回転軸を回転させると、駆動回転軸はその嵌合凸部がバネ力により巻回コアの端面を押しながら、巻回コアに対して空回りを始めて、自動的に駆動回転軸の嵌合凸部は、巻回コアの嵌合凹部に整合した状態になり、その時に嵌合凸部は嵌合凹部内に陥入して、凹凸が互いに噛み合って嵌合状態になり、駆動回転軸の動力が巻回コアに伝達されるものであり、凹凸嵌合し易くなり、巻回コアを熱転写プリンタの駆動回転軸にセットし易くなる。 In addition, when the rotational phase position of the fitting concave part of the winding core and the fitting convex part of the driving rotary shaft are not aligned with each other or in a state where they interfere with each other before fitting, the driving rotary shaft is rotated. Then, the drive rotating shaft begins to idle with respect to the winding core while the fitting convex portion presses the end surface of the winding core by the spring force, and the driving rotating shaft automatically engages with the winding convex portion. The mating convex part is indented into the mating concave part at that time, and the concave and convex parts engage with each other to be in the mating state, and the power of the drive rotating shaft is applied to the winding core. It is transmitted, and it becomes easy to fit the concave and convex, and it becomes easy to set the winding core on the drive rotation shaft of the thermal transfer printer.

このように、熱転写プリンタにおけるインクリボンや転写フィルム等のフィルムの巻出し巻取り巻回コアの装着において、装着操作に気を使う煩わしさが軽減され、慣れない操作でもセットが容易にでき、巻回コアの嵌合凹部を駆動回転軸の嵌合凸部にしっかり整合させる操作を要することなく、凹凸噛み合わせによる装着が可能になり、巻回コアの装着ミスによる熱転写プリンタにおけるウエブロール状のフィルムの巻き出し、巻き取り送行フィード中のトラブルの発生や、プリントの損失を防止できるものである。   In this way, in the installation of a winding core for winding a film such as an ink ribbon or a transfer film in a thermal transfer printer, the troublesomeness of taking care of the mounting operation is reduced, and the setting can be easily performed even with an unfamiliar operation. Without requiring an operation to firmly align the fitting recess of the winding core with the fitting projection of the drive rotating shaft, it is possible to mount by concavity and convexity engagement, and a web roll film in a thermal transfer printer due to incorrect mounting of the winding core It is possible to prevent troubles occurring during unwinding, winding and feeding, and loss of printing.
