特開２０１９－１７１６１１号公報JP 2019-171611 A
　しかしながら、特許文献１の箔転写装置では、供給リールを回転させることなく箔フィルムを検知することができないため、箔フィルムが有る状態では、箔フィルムが無駄となり、箔フィルムが無い状態では、シートが加熱ローラなどの加熱部材や加圧ローラなどの加圧部材などに巻き付くおそれがあるという問題点があった。 However, in the foil transfer device of Patent Document 1, the foil film cannot be detected without rotating the supply reel. There is a problem that it may wind around a heating member such as a heating roller or a pressure member such as a pressure roller.
　そこで、本発明は、供給リールを回転させることなく、転写位置より上流側の箔フィルムの有無を検知することを目的とする。 Therefore, an object of the present invention is to detect the presence or absence of a foil film on the upstream side of the transfer position without rotating the supply reel.
　前記課題を解決するための箔転写装置は、箔を含む箔フィルムにシートを重ねて、シート上の画像に箔を転写する箔転写装置であって、ヒータを有し、箔フィルムおよびシートを加熱する加熱部材と、加熱部材との間で箔フィルムおよびシートを挟む加圧部材と、箔フィルムが巻回される供給リールと、供給リールから供給された箔フィルムを巻き取る巻取リールと、巻取リールを駆動させるモータと、供給リールに巻回された箔フィルム、または、加熱部材と供給リールの間の箔フィルムをモータを駆動させることなく検知可能なフィルムセンサと、を備える。 A foil transfer device for solving the above-described problems is a foil transfer device that stacks a sheet on a foil film containing foil and transfers the foil to an image on the sheet, and has a heater to heat the foil film and the sheet. a heating member, a pressure member for sandwiching the foil film and the sheet between the heating member, a supply reel on which the foil film is wound, a winding reel for winding the foil film supplied from the supply reel, and a winding reel. A motor for driving the take-up reel and a film sensor capable of detecting the foil film wound around the supply reel or the foil film between the heating member and the supply reel without driving the motor are provided.
　この構成によれば、フィルムセンサによって、供給リールを回転させることなく転写位置より上流側の箔フィルムの有無を検知できる。 According to this configuration, the presence or absence of the foil film on the upstream side of the transfer position can be detected by the film sensor without rotating the supply reel.
　前記した構成において、箔転写装置は制御部をさらに備え、制御部は、箔フィルムをシートに転写する指示を受けた場合において、箔フィルムセンサによって箔フィルムの有無を判定し、箔フィルムがあると判定した場合、シートを搬送し、箔フィルムがあると判定しない場合、シートを搬送しない構成としてもよい。 In the configuration described above, the foil transfer device further includes a control unit, and when receiving an instruction to transfer the foil film to the sheet, the control unit determines the presence or absence of the foil film by means of the foil film sensor. A configuration may be adopted in which the sheet is transported when it is determined, and the sheet is not transported when it is not determined that there is a foil film.
　この構成によれば、箔フィルムが無い状態においてシートが搬送された場合には、シートが加熱部材に巻き付いてしまうおそれがあるところ、箔フィルムがあると判定しなかった場合にシートを搬送しないので、シートが加熱部材に巻き付いてしまうことを抑制できる。 According to this configuration, if the sheet is conveyed without the foil film, there is a risk that the sheet will wind around the heating member. , the sheet can be prevented from winding around the heating member.
　前記した構成において、フィルムセンサは、箔フィルムに当てた反射光を検知可能な反射センサである構成としてもよい。 In the above configuration, the film sensor may be configured as a reflective sensor capable of detecting reflected light applied to the foil film.
　前記した構成において、フィルムセンサは、加熱部材と供給リールの間の箔フィルムに向けて光を出射する出射部と、出射部との間に箔フィルムが位置するように配置され、箔フィルムが無い場合に出射部が出射した光を受光する受光部と、を有する構成としてもよい。 In the above-described configuration, the film sensor is arranged so that the foil film is positioned between the emitting portion that emits light toward the foil film between the heating member and the supply reel and the emitting portion, and there is no foil film. and a light receiving portion for receiving the light emitted by the emitting portion.
　前記した構成において、フィルムセンサは、箔フィルムを撮影するカメラである構成としてもよい。 In the above configuration, the film sensor may be configured as a camera for photographing the foil film.
　前記した構成において、フィルムセンサは、加熱部材と供給リールの間の箔フィルムに接触可能に配置されたアクチュエータであって、箔フィルムが有る場合に第１位置に位置し、箔フィルムが無い場合に第２位置に位置するアクチュエータを含んでなる構成としてもよい。 In the configuration described above, the film sensor is an actuator arranged so as to be able to contact the foil film between the heating member and the supply reel, and is located at the first position when the foil film is present, and is positioned at the first position when the foil film is absent. The configuration may include an actuator positioned at the second position.
　前記した構成において、アクチュエータは、箔フィルムに所定のテンションを付与する構成としてもよい。 In the configuration described above, the actuator may be configured to apply a predetermined tension to the foil film.
　この構成によれば、アクチュエータがフィルムセンサとテンションを付与する部材とを兼ねるので、部品点数を減らすことができる。 According to this configuration, the actuator serves both as a film sensor and as a member that applies tension, so the number of parts can be reduced.
　前記した構成において、箔転写装置は、制御部をさらに備え、供給リールに第１幅の箔フィルムが巻回された第１カートリッジと、第１幅より小さい第２幅の箔フィルムが巻回され、箔フィルムが供給リールの軸方向の中央に配置された第２カートリッジと、第２幅の箔フィルムが巻回され、箔フィルムが軸方向の一方側に寄せられて配置された第３カートリッジと、を選択的に装着可能であり、フィルムセンサは、軸方向の中央に位置する第１フィルムセンサと、軸方向の一方側に寄せられて配置された第２フィルムセンサと、を含み、制御部は、第１フィルムセンサおよび第２フィルムセンサが箔フィルムを検知した場合、第１カートリッジが装着されていると判定し、第１フィルムセンサが箔フィルムを検知し、かつ、第２フィルムセンサが箔フィルムを検知しない場合、第２カートリッジが装着されていると判定し、第１フィルムセンサが箔フィルムを検知せず、かつ、第２フィルムセンサが箔フィルムを検知した場合、第３カートリッジが装着されていると判定する構成としてもよい。 In the configuration described above, the foil transfer device further includes a controller, a first cartridge in which a foil film having a first width is wound around a supply reel, and a foil film in which a second width smaller than the first width is wound. a second cartridge in which the foil film is arranged in the center of the supply reel in the axial direction; and a third cartridge in which the foil film of the second width is wound and arranged so that the foil film is shifted to one side in the axial direction. , and the film sensor includes a first film sensor located in the center in the axial direction and a second film sensor located closer to one side in the axial direction. determines that the first cartridge is loaded when the first film sensor and the second film sensor detect the foil film, the first film sensor detects the foil film, and the second film sensor detects the foil film If the film is not detected, it is determined that the second cartridge is loaded, and if the first film sensor does not detect the foil film and the second film sensor detects the foil film, the third cartridge is loaded. It is good also as a structure which determines that it is.
　この構成によれば、フィルムセンサがカートリッジの種類を検知するフィルム幅センサを兼ねることで、別途にフィルム幅センサを設ける必要がなくなる。 According to this configuration, the film sensor also serves as a film width sensor for detecting the type of cartridge, eliminating the need to provide a separate film width sensor.
　前記した構成において、供給リールは、箔フィルムが巻回される巻芯を有し、フィルムセンサは、巻芯に巻回された箔フィルムを検知可能である構成としてもよい。 In the above configuration, the supply reel may have a core around which the foil film is wound, and the film sensor may be configured to detect the foil film wound around the core.
　前記した構成において、巻芯は、周面に設けられたスリットであって、箔フィルムが巻回されている場合、箔フィルムに覆われるスリットを有し、フィルムセンサは、巻芯に箔フィルムが巻回されている場合、箔フィルムを検知し、スリットを検知せず、巻芯に箔フィルムが巻回されていない場合、箔フィルムを検知せず、スリットを検知可能である構成としてもよい。 In the configuration described above, the winding core has a slit provided on the peripheral surface and is covered with the foil film when the foil film is wound, and the film sensor has the slit that is covered with the foil film on the winding core. If the foil film is wound, the foil film is detected, but the slit is not detected. If the foil film is not wound around the core, the foil film is not detected, but the slit can be detected.
　この構成によれば、箔フィルムが巻回されていない巻芯のスリットを検知することで、箔フィルムがないことを確実に検知できる。 According to this configuration, it is possible to reliably detect the absence of the foil film by detecting the slit in the core on which the foil film is not wound.
　本発明によれば、供給リールを回転させることなく、転写位置より上流側の箔フィルムの有無を検知することができる。 According to the present invention, the presence or absence of the foil film on the upstream side of the transfer position can be detected without rotating the supply reel.

1 and the like, for the sake of convenience, the state in which the foil film F is maximally wound around both the supply reel 31 and the take-up reel 35 is illustrated.
　第１案内軸４１は、供給リール３１から引き出される箔フィルムＦの進行方向を変更するための軸である。
　第２案内軸４２は、第１案内軸４１で案内された箔フィルムＦの進行方向を変更するための軸である。
　第３案内軸４３は、第２案内軸４２で案内された箔フィルムＦの進行方向を変更して巻取リール３５に案内する軸である。 The first guide shaft 41 is a shaft for changing the traveling direction of the foil film F drawn from the supply reel 31 .
The second guide shaft 42 is a shaft for changing the traveling direction of the foil film F guided by the first guide shaft 41 .
The third guide shaft 43 is a shaft that changes the traveling direction of the foil film F guided by the second guide shaft 42 and guides it to the take-up reel 35 .
　第１案内軸４１は、トナー像を下にした状態で搬送されるシートＳに対して、供給リール３１から引き出された箔フィルムＦを下から重ねるように案内している。第１案内軸４１は、供給リール３１から引き出された箔フィルムＦの搬送方向を変えて、シートＳの搬送方向と略平行に箔フィルムＦを案内する。 The first guide shaft 41 guides the foil film F pulled out from the supply reel 31 so as to overlap the sheet S conveyed with the toner image facing down from below. The first guide shaft 41 changes the conveying direction of the foil film F drawn from the supply reel 31 and guides the foil film F substantially parallel to the sheet S conveying direction.
　第２案内軸４２は、転写部５０を通過した箔フィルムＦと接触し、転写部５０を通過した箔フィルムＦの搬送方向をシートＳの搬送方向とは異なる方向に変更している。転写部５０を通過してシートＳと重なった状態で搬送された箔フィルムＦは、第２案内軸４２を通過する際にシートＳとは異なる方向に案内され、シートＳから剥離される。 The second guide shaft 42 comes into contact with the foil film F that has passed through the transfer section 50, and changes the conveying direction of the foil film F that has passed through the transferring section 50 to a direction different from the conveying direction of the sheet S. The foil film F that has passed through the transfer section 50 and is conveyed while overlapping the sheet S is guided in a direction different from that of the sheet S when passing through the second guide shaft 42 and separated from the sheet S.
　転写部５０は、シートＳと箔フィルムＦを挟んだ状態で加熱および加圧することで、シートＳに形成されたトナー像の上に転写層Ｆ２２を転写するための部分である。転写部５０は、加圧部材の一例としての加圧ローラ５１と、加熱部材の一例としての加熱ローラ６１と、圧接離間機構７０とを備えている。転写部５０は、加圧ローラ５１と加熱ローラ６１のニップ部において、シートＳと箔フィルムＦを重ねて加熱および加圧する。 The transfer portion 50 is a portion for transferring the transfer layer F22 onto the toner image formed on the sheet S by applying heat and pressure while sandwiching the sheet S and the foil film F. The transfer section 50 includes a pressure roller 51 as an example of a pressure member, a heating roller 61 as an example of a heating member, and a pressure contact/separation mechanism 70 . The transfer unit 50 heats and presses the sheet S and the foil film F in a nip portion between the pressure roller 51 and the heating roller 61 .
　加圧ローラ５１は、円筒状の芯金の周囲をシリコンゴムからなるゴム層で被覆したローラである。加圧ローラ５１は、箔フィルムＦの上側に配置され、シートＳの裏面（トナー像が形成された面と反対側の面）と接触可能となっている。 The pressure roller 51 is a roller in which a rubber layer made of silicone rubber covers the circumference of a cylindrical cored bar. The pressure roller 51 is arranged above the foil film F and is capable of contacting the back surface of the sheet S (the surface opposite to the surface on which the toner image is formed).
　加圧ローラ５１は、両端部がカバー２２に回転可能に支持されている。加圧ローラ５１は、加熱ローラ６１との間でシートＳおよび箔フィルムＦを挟み、モータＭによって回転駆動されることで加熱ローラ６１を従動回転させる。このように加圧ローラ５１と加熱ローラ６１との間でシートＳおよび箔フィルムＦを挟んだ状態で、加圧ローラ５１および加熱ローラ６１が回転することで、シートＳおよび箔フィルムＦが搬送される。 Both ends of the pressure roller 51 are rotatably supported by the cover 22 . The pressure roller 51 sandwiches the sheet S and the foil film F between itself and the heating roller 61 , and is rotationally driven by the motor M so that the heating roller 61 is driven to rotate. With the sheet S and the foil film F sandwiched between the pressure roller 51 and the heating roller 61, the pressure roller 51 and the heating roller 61 are rotated to convey the sheet S and the foil film F. be.
　加熱ローラ６１は、円筒状に形成された金属管の内部にヒータＨを配置したローラであり、ヒータＨによって加熱され、箔フィルムＦおよびシートＳを加熱している。加熱ローラ６１は、箔フィルムＦの下側に配置され、箔フィルムＦと接触している。 The heating roller 61 is a roller in which a heater H is arranged inside a cylindrically formed metal tube, and is heated by the heater H to heat the foil film F and the sheet S. The heating roller 61 is arranged below the foil film F and is in contact with the foil film F. As shown in FIG.
　圧接離間機構７０は、加圧ローラ５１および加熱ローラ６１の状態を、加圧ローラ５１と加熱ローラ６１で箔フィルムＦを挟んだ圧接状態と、少なくとも１つのローラが箔フィルムＦから離れた離間状態とに切り替えるための機構である。本実施形態では、圧接離間機構７０は、加熱ローラ６１を、図１に実線で示す圧接位置と、図１に仮想線で示す離間位置との間で移動させることで、加熱ローラ６１を箔フィルムＦに対して接触・離間させている。つまり、圧接離間機構７０は、加熱ローラ６１を箔フィルムＦから離すことで、加圧ローラ５１および加熱ローラ６１の状態を、離間状態にする。また、圧接離間機構７０は、加熱ローラ６１を箔フィルムＦに圧接させることで、加圧ローラ５１および加熱ローラ６１の状態を、圧接状態にする。 The pressure contact/separation mechanism 70 changes the states of the pressure roller 51 and the heat roller 61 into a pressure contact state in which the foil film F is sandwiched between the pressure roller 51 and the heat roller 61 and a separated state in which at least one roller is separated from the foil film F. It is a mechanism for switching between In this embodiment, the pressure contact/separation mechanism 70 moves the heating roller 61 between the pressure contact position indicated by the solid line in FIG. 1 and the separation position indicated by the phantom line in FIG. It is in contact with/separated from F. In other words, the pressing/separating mechanism 70 separates the heating roller 61 from the foil film F, thereby separating the pressure roller 51 and the heating roller 61 from each other. Further, the pressing/separating mechanism 70 presses the heating roller 61 against the foil film F, thereby bringing the pressure roller 51 and the heating roller 61 into the pressing state.
　制御部３００は、ＣＰＵ、ＲＡＭ、ＲＯＭ、入出力回路など、を備えている。制御部３００は、ＲＡＭ、ＲＯＭなどに記憶されたプログラムやデータに基づいて各種演算処理を行うことによって、制御を実行する。 The control unit 300 includes a CPU, RAM, ROM, input/output circuits, and the like. The control unit 300 executes control by performing various arithmetic processing based on programs and data stored in RAM, ROM, and the like.
　モータＭは、図示せずギヤ列を介して、巻取リール３５および加圧ローラ５１を回転駆動させる。なお、巻取リール３５および加圧ローラ５１を別々のモータで駆動させてもよい。 The motor M rotates the take-up reel 35 and the pressure roller 51 via a gear train (not shown). Note that the take-up reel 35 and the pressure roller 51 may be driven by separate motors.
　このように構成された箔転写装置１では、シートＳの表面を下向きにしてシートトレイ３に載置されたシートＳが、シート供給機構１１により一枚ずつ転写部５０に向けて搬送される。シートＳは、転写部５０のシート搬送方向における上流側で、供給リール３１から供給された箔フィルムＦと重ねられ、シートＳのトナー像と箔フィルムＦが接触した状態で転写部５０に搬送される。 In the foil transfer device 1 configured as described above, the sheets S placed on the sheet tray 3 with the surface of the sheets S facing downward are conveyed one by one toward the transfer section 50 by the sheet supply mechanism 11 . The sheet S is superimposed on the foil film F supplied from the supply reel 31 on the upstream side of the transfer section 50 in the sheet conveying direction, and conveyed to the transfer section 50 in a state in which the toner image of the sheet S and the foil film F are in contact with each other. be.
　転写部５０においては、シートＳと箔フィルムＦが加圧ローラ５１と加熱ローラ６１の間のニップ部を通過する際に、加熱ローラ６１と加圧ローラ５１により加熱および加圧され、トナー像の上に転写層Ｆ２２が転写される。なお、以下の説明では、トナー像への転写層Ｆ２２の転写を、単に「箔転写」とも称する。 In the transfer section 50, the sheet S and the foil film F are heated and pressed by the heating roller 61 and the pressure roller 51 when passing through the nip portion between the pressure roller 51 and the heating roller 61, and the toner image is formed. A transfer layer F22 is transferred thereon. In the following description, the transfer of the transfer layer F22 to the toner image is also simply referred to as "foil transfer".
　箔転写が行われた後、シートＳと箔フィルムＦは密着した状態で第２案内軸４２まで搬送される。シートＳと箔フィルムＦが第２案内軸４２を通過すると、箔フィルムＦの搬送方向がシートＳの搬送方向と異なる方向に変わるため、シートＳから箔フィルムＦが剥離される。 After the foil transfer is performed, the sheet S and the foil film F are transported to the second guide shaft 42 while being in close contact with each other. When the sheet S and the foil film F pass through the second guide shaft 42, the foil film F is peeled off from the sheet S because the direction in which the foil film F is conveyed changes to a direction different from the direction in which the sheet S is conveyed.
　シートＳから剥離された箔フィルムＦは、巻取リール３５に巻き取られていく。一方、箔フィルムＦが剥離されたシートＳは、シート排出機構１２によって、箔が転写された表面を下に向けた状態で、筐体２の外部に排出される。 The foil film F separated from the sheet S is taken up by the take-up reel 35 . On the other hand, the sheet S from which the foil film F has been peeled off is discharged to the outside of the housing 2 by the sheet discharge mechanism 12 with the surface to which the foil has been transferred facing downward.
　ここで、図３（ａ）～（ｃ）に示すような複数種類の幅の箔フィルムを備えるフィルムカートリッジＦＣを装着可能である。具体的に、箔転写装置１は、第１カートリッジＦＣ１と、第２カートリッジＦＣ２と、第３カートリッジＦＣ３とを選択的に装着可能である。 Here, it is possible to mount a film cartridge FC having foil films of a plurality of widths as shown in FIGS. 3(a) to 3(c). Specifically, the foil transfer apparatus 1 can selectively mount the first cartridge FC1, the second cartridge FC2, and the third cartridge FC3.
　図３（ａ）に示すように、第１カートリッジＦＣ１は、供給リール３１に第１幅Ｈ１の箔フィルムＦが巻回されたカートリッジである。第１幅Ｈ１は、フィルムカートリッジＦＣに配置可能な箔フィルムＦの最大幅であり、一例として、２２０ｍｍである。図４に示すように、第１幅Ｈ１の箔フィルムＦは、全幅領域Ｒ１に装着される。 As shown in FIG. 3(a), the first cartridge FC1 is a cartridge in which a foil film F having a first width H1 is wound around a supply reel 31. As shown in FIG. The first width H1 is the maximum width of the foil film F that can be placed in the film cartridge FC, and is, for example, 220 mm. As shown in FIG. 4, a foil film F having a first width H1 is attached to the full width region R1.
　図３（ｂ）に示すように、第２カートリッジＦＣ２は、第２幅Ｈ２の箔フィルムＦが巻回され、箔フィルムＦが軸方向の中央に配置されたカートリッジである。第２幅Ｈ２は、第１幅Ｈ１より小さく、一例として、１１０ｍｍである。図４に示すように、第２幅Ｈ２の箔フィルムＦは、軸方向における中央線Ｃ（図４に一点鎖線で示している）に寄せた中央領域Ｒ２に装着される。 As shown in FIG. 3(b), the second cartridge FC2 is a cartridge in which a foil film F having a second width H2 is wound and the foil film F is arranged in the center in the axial direction. The second width H2 is smaller than the first width H1, and is, for example, 110 mm. As shown in FIG. 4, the foil film F having the second width H2 is mounted in a central region R2 that is close to the axial center line C (indicated by the dashed line in FIG. 4).
　図３（ｃ）に示すように、第３カートリッジＦＣ３は、第２幅Ｈ２の箔フィルムＦが巻回され、箔フィルムＦが軸方向の一方側に寄せられて配置されたカートリッジである。図４に示すように、第３の幅Ｈ３の箔フィルムＦは、軸方向における一方側（図４における左側）に寄せた片寄せ領域Ｒ３に装着される。 As shown in FIG. 3(c), the third cartridge FC3 is a cartridge in which a foil film F having a second width H2 is wound and arranged so that the foil film F is shifted to one side in the axial direction. As shown in FIG. 4, the foil film F having the third width H3 is attached to the one-sided region R3 that is shifted to one side (left side in FIG. 4) in the axial direction.
　図５に示すように、箔転写装置１は、フィルムセンサ１１０をさらに備えている。フィルムセンサ１１０は、装置本体２１に配置されている。フィルムセンサ１１０は、供給リール３１に巻回された箔フィルムＦ、または、加熱ローラ６１と供給リール３１の間の箔フィルムＦを検知可能である。本実施形態では、フィルムセンサ１１０は、加熱ローラ６１と供給リール３１の間の箔フィルムＦを検知可能である。具体的には、フィルムセンサ１１０は、第１案内軸４１と供給リール３１の間であって、箔フィルムＦの上側に配置されており、箔フィルムＦのオモテ面（接着層Ｆ２３側）を検知するようになっている。 As shown in FIG. 5, the foil transfer device 1 further includes a film sensor 110. As shown in FIG. The film sensor 110 is arranged in the apparatus main body 21 . The film sensor 110 can detect the foil film F wound around the supply reel 31 or the foil film F between the heating roller 61 and the supply reel 31 . In this embodiment, the film sensor 110 can detect the foil film F between the heating roller 61 and the supply reel 31 . Specifically, the film sensor 110 is arranged above the foil film F between the first guide shaft 41 and the supply reel 31, and detects the front surface (adhesive layer F23 side) of the foil film F. It is designed to
　フィルムセンサ１１０は、箔フィルムＦをモータＭを駆動させることなく検知可能である。言い換えると、フィルムセンサ１１０は、箔フィルムＦを、箔フィルムＦが停止している状態であっても、箔フィルムＦが搬送されている状態であっても検知可能である。フィルムセンサ１１０が箔フィルムＦを検知した検知信号は、制御部３００に送られる。 The film sensor 110 can detect the foil film F without driving the motor M. In other words, the film sensor 110 can detect the foil film F whether the foil film F is stopped or being transported. A detection signal of the foil film F detected by the film sensor 110 is sent to the controller 300 .
　フィルムセンサ１１０は、箔フィルムＦに当てた反射光を検知可能な反射センサである。詳しくは、フィルムセンサ１１０は、加熱ローラ６１と供給リール３１の間の箔フィルムＦに向けて光を出射し、箔フィルムＦによって反射された反射光を検知した場合に検知信号を制御部３００に送り、反射光を検知しない場合に検知信号を制御部３００に送らないようになっている。 The film sensor 110 is a reflective sensor capable of detecting reflected light applied to the foil film F. Specifically, the film sensor 110 emits light toward the foil film F between the heating roller 61 and the supply reel 31, and sends a detection signal to the control unit 300 when the reflected light reflected by the foil film F is detected. A detection signal is not sent to the control unit 300 when the reflected light is not detected.
　図４に示すように、フィルムセンサ１１０は、軸方向の中央に位置する第１フィルムセンサ１１１と、軸方向の一方側に寄せられて配置された第２フィルムセンサ１１２と、を含む。第１フィルムセンサ１１１は、中央領域Ｒ２内であって、かつ、片寄せ領域Ｒ３外の領域に配置されている。第２フィルムセンサ１１２は、片寄せ領域Ｒ３内であって、かつ、中央領域Ｒ２外の領域に配置されている。 As shown in FIG. 4, the film sensor 110 includes a first film sensor 111 located in the center in the axial direction, and a second film sensor 112 located closer to one side in the axial direction. The first film sensor 111 is arranged within the central region R2 and outside the one-sided region R3. The second film sensor 112 is arranged within the one-sided region R3 and outside the central region R2.
　次に、制御部３００が供給リール３１に巻回された箔フィルムＦの有無を検知する制御について説明する。
　上述したように、制御部３００は、箔フィルムＦが停止している状態であっても、箔フィルムＦが搬送されている状態であっても、箔フィルムＦの有無を検知可能であり、画像形成装置の電源がＯＮであるときには、常に箔フィルムＦの有無を検知するようになっている。制御部３００は、フィルムセンサ１１０から検出信号が送られている場合、供給リール３１に巻回された箔フィルムＦが有ると判定し、検出信号が送られていない場合、供給リール３１に巻回された箔フィルムＦが無いと判定する。 Next, the control performed by the control unit 300 to detect the presence or absence of the foil film F wound around the supply reel 31 will be described.
As described above, the control unit 300 can detect the presence or absence of the foil film F whether the foil film F is stopped or being conveyed. The presence or absence of the foil film F is always detected when the power of the forming apparatus is ON. The control unit 300 determines that there is a foil film F wound around the supply reel 31 when the detection signal is sent from the film sensor 110, and winds the supply reel 31 when the detection signal is not sent. It is determined that there is no foil film F that has been applied.
　制御部３００は、箔フィルムＦをシートＳに転写する指示を受けた場合において、箔フィルムセンサ１１０によって箔フィルムＦの有無を判定する。この場合において、制御部３００は、箔フィルムＦがあると判定した場合、シートＳを搬送し、箔フィルムＦがあると判定しない場合、シートＳを搬送しない。例えば、制御部３００は、シートＳの搬送開始前に箔フィルムＦが無いことを判定した場合には、シートＳの搬送を開始しない。 When receiving an instruction to transfer the foil film F to the sheet S, the control unit 300 determines the presence or absence of the foil film F using the foil film sensor 110 . In this case, if the control unit 300 determines that the foil film F is present, the sheet S is transported, and if it is not determined that the foil film F is present, the control unit 300 does not transport the sheet S. For example, if the control unit 300 determines that there is no foil film F before the sheet S starts to be conveyed, the sheet S does not start to be conveyed.
　また、フィルムカートリッジＦＣの検知に関し、制御部３００は、第１フィルムセンサ１１１および第２フィルムセンサ１１２の両方が箔フィルムＦを検知した場合、第１カートリッジＦＣ１が装着されていると判定する。
　また、制御部３００は、第１フィルムセンサ１１１が箔フィルムＦを検知し、かつ、第２フィルムセンサ１１２が箔フィルムＦを検知しない場合、第２カートリッジＦＣ２が装着されていると判定する。
　また、制御部３００は、第１フィルムセンサ１１１が箔フィルムＦを検知せず、かつ、第２フィルムセンサ１１２が箔フィルムＦを検知した場合、第３カートリッジＦＣ３が装着されていると判定する。
　このように、本実施形態では、第１フィルムセンサ１１１および第２フィルムセンサ１１２がカートリッジの種類を検知するフィルム幅センサを兼ねている。 Regarding the detection of the film cartridge FC, when both the first film sensor 111 and the second film sensor 112 detect the foil film F, the controller 300 determines that the first cartridge FC1 is loaded.
Further, when the first film sensor 111 detects the foil film F and the second film sensor 112 does not detect the foil film F, the controller 300 determines that the second cartridge FC2 is loaded.
If the first film sensor 111 does not detect the foil film F and the second film sensor 112 detects the foil film F, the control unit 300 determines that the third cartridge FC3 is loaded.
Thus, in this embodiment, the first film sensor 111 and the second film sensor 112 also serve as film width sensors for detecting the type of cartridge.
　次に、制御部３００が実行する処理の一例について、図６のフローチャートを参照して説明する。 Next, an example of processing executed by the control unit 300 will be described with reference to the flowchart of FIG.
　制御部３００は、箔フィルムＦをシートＳに転写する箔転写の指示を受けた場合（Ｓ１，Ｙｅｓ）、箔フィルムＦが有るかを判定する（Ｓ２）。箔フィルムＦが有るか無いかの判定は、フィルムセンサ１１０からの検知信号が有るか無いかで判定される。 When receiving a foil transfer instruction to transfer the foil film F to the sheet S (S1, Yes), the control unit 300 determines whether the foil film F is present (S2). Whether or not the foil film F is present is determined by whether or not there is a detection signal from the film sensor 110 .
　ステップＳ２において、制御部３００は、箔フィルムＦが有ると判定しなかった場合（Ｓ２，Ｎｏ）、モータＭを駆動させず、シートを搬送しない。すなわち箔転写を実行することなく処理を終了する。 In step S2, if the control unit 300 does not determine that the foil film F is present (S2, No), it does not drive the motor M and does not convey the sheet. That is, the process ends without performing foil transfer.
　ステップＳ２において、制御部３００は、箔フィルムＦが有ると判定した場合（Ｓ２，Ｙｅｓ）、モータＭを駆動し（Ｓ３）、シートを搬送する（Ｓ４）。これにより、箔転写処理が開始される。 In step S2, when the control unit 300 determines that the foil film F is present (S2, Yes), it drives the motor M (S3) and conveys the sheet (S4). This starts the foil transfer process.
　ステップＳ４の後、制御部３００は、箔転写が終了するまで（Ｓ６，Ｙｅｓ）箔フィルムＦが有るかの判定を常に実行し続ける（Ｓ５）。 After step S4, the control unit 300 continues to determine whether or not the foil film F is present (S5) until the foil transfer is completed (S6, Yes).
　ステップＳ５において、制御部３００は、箔フィルムＦが有ると判定しない場合（Ｓ５，Ｎｏ）、箔転写の実行中に箔フィルムＦが無くなったので、現在搬送中のシートＳを排出した後（Ｓ７）、モータＭを停止して（Ｓ８）、処理を終了する。 In step S5, if the control unit 300 does not determine that the foil film F is present (S5, No), the foil film F runs out during the foil transfer, so the sheet S currently being conveyed is discharged (S7 ), the motor M is stopped (S8), and the process ends.
　ステップＳ５において、制御部３００は、箔フィルムＦが有ると判定し（Ｓ５，Ｙｅｓ）、かつ、箔転写が終了した場合（Ｓ６，Ｙｅｓ）、モータＭを停止して（Ｓ８）、処理を終了する。 In step S5, the control unit 300 determines that the foil film F is present (S5, Yes), and when the foil transfer is completed (S6, Yes), stops the motor M (S8), and ends the process. do.
　以上に説明した、本実施形態によれば、以下のような効果を得ることができる。
　箔転写装置１によれば、フィルムセンサ１１０によって、供給リール３１を回転させることなく転写位置より上流側の箔フィルムＦの有無を検知できる。 According to this embodiment described above, the following effects can be obtained.
According to the foil transfer apparatus 1 , the presence or absence of the foil film F on the upstream side of the transfer position can be detected by the film sensor 110 without rotating the supply reel 31 .
　また、箔フィルムＦが無い状態においてシートＳが搬送された場合には、シートＳが加熱ローラ６１や加圧ローラ５１に巻き付いてしまうおそれがあるところ、制御部３００は、箔フィルムＦをシートＳに転写する指示を受けた場合において、箔フィルムＦがあると判定しない場合、シートＳを搬送しないので、シートＳが加熱ローラ６１や加圧ローラ５１に巻き付いてしまうことを抑制できる。 Further, if the sheet S is conveyed without the foil film F, the sheet S may wind around the heating roller 61 or the pressure roller 51. , the sheet S is not conveyed if it is not determined that the foil film F is present, so that the sheet S can be prevented from winding around the heating roller 61 or the pressure roller 51 .
　また、フィルムセンサ１１０（第１フィルムセンサ１１１および第２フィルムセンサ１１２）がカートリッジの種類を検知するフィルム幅センサを兼ねることで、別途にフィルム幅センサを設ける必要がなくなる。 Also, since the film sensor 110 (the first film sensor 111 and the second film sensor 112) also serves as a film width sensor for detecting the type of cartridge, there is no need to separately provide a film width sensor.
　次に、図７を参照して本発明の第２実施形態について説明する。第２実施形態では、フィルムセンサ１１０が供給リール３１の巻芯３１Ｍに巻回されている箔フィルムＦを検知する構成である点が第１実施形態と異なる。以下の説明においては、第１実施形態と略同様の構造となる部材には同一の符号を付し、その説明は省略する。 Next, a second embodiment of the present invention will be described with reference to FIG. The second embodiment is different from the first embodiment in that the film sensor 110 detects the foil film F wound around the core 31M of the supply reel 31 . In the following description, members having substantially the same structure as in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.
　図７（ｂ）に示すように、供給リール３１は、箔フィルムＦが巻回される巻芯３１Ｍを有している。第２実施形態におけるフィルムセンサ１２０は、フィルムセンサ１２０は、巻芯３１Ｍに箔フィルムＦが巻回されている場合、箔フィルムＦを検知し、巻芯３１Ｍに箔フィルムＦが巻回されていない場合、箔フィルムＦを検知しない。 As shown in FIG. 7(b), the supply reel 31 has a winding core 31M around which the foil film F is wound. The film sensor 120 in the second embodiment detects the foil film F when the foil film F is wound around the core 31M, and the foil film F is not wound around the core 31M. In this case, the foil film F is not detected.
　具体的に、巻芯３１Ｍは、スリット３１Ｓを有している。スリット３１Ｓは、巻芯３１Ｍの周面に設けられており、巻芯３１Ｍの周方向に全周に渡って延びる切り欠きである。
　図７（ａ）に示すように、箔フィルムＦが巻芯３１Ｍに巻回されている場合、スリット３１Ｓは、箔フィルムＦに覆われている。この場合、フィルムセンサ１２０は、スリット３１Ｓを検知せず、供給リール３１に箔フィルムＦが有ることを示す信号を制御部３００に送る。
　図７（ｂ）に示すように、箔フィルムＦが巻芯３１Ｍに巻回されていない場合、スリット３１Ｓは、箔フィルムＦに覆われておらず露出している。この場合、フィルムセンサ１２０は、スリット３１Ｓを検知して、供給リール３１に箔フィルムＦが無いことを示す信号を制御部３００に送る。 Specifically, the winding core 31M has a slit 31S. The slit 31S is provided on the peripheral surface of the winding core 31M, and is a notch extending along the entire circumference of the winding core 31M in the circumferential direction.
As shown in FIG. 7A, when the foil film F is wound around the core 31M, the slit 31S is covered with the foil film F. As shown in FIG. In this case, the film sensor 120 does not detect the slit 31S, and sends a signal to the controller 300 indicating that the foil film F is present on the supply reel 31. FIG.
As shown in FIG. 7B, when the foil film F is not wound around the core 31M, the slit 31S is not covered with the foil film F and is exposed. In this case, the film sensor 120 detects the slit 31S and sends a signal to the controller 300 indicating that there is no foil film F on the supply reel 31 .
　以上のように説明した第２実施形態によれば、箔フィルムＦが巻回されていない巻芯３１Ｍのスリット３１Ｓを検知することで、箔フィルムＦがないことを確実に検知できる。 According to the second embodiment described above, the absence of the foil film F can be reliably detected by detecting the slit 31S of the core 31M on which the foil film F is not wound.
　また、第２実施例におけるスリット３１Ｓは、図８（ａ）のように、軸方向に延びるスリット３１Ｋであってよい。 Also, the slit 31S in the second embodiment may be a slit 31K extending in the axial direction, as shown in FIG. 8(a).
　また、図８（ｂ）に示すように、第２実施形態におけるスリット３１Ｓの代わりに、巻芯３１Ｍにシボ加工されたシボ部分３１Ｚを有する構成であってもよい。この構成では、シボ部分３１Ｚにフィルムセンサ１２０の光が当たると光が乱反射するので、箔フィルムＦがないことを検知できる。 Further, as shown in FIG. 8(b), instead of the slits 31S in the second embodiment, the winding core 31M may have a textured portion 31Z. In this configuration, when the light from the film sensor 120 hits the embossed portion 31Z, the light is diffusely reflected, so that the absence of the foil film F can be detected.
　次に、図９を参照して本発明の第３実施形態について説明する。第３実施形態では、箔フィルムＦに接触するアクチュエータ１３１を使用して箔フィルムＦを検知する構成であるところが第１実施形態と異なる。以下の説明においては、第１実施形態と略同様の構造となる部材には同一の符号を付し、その説明は省略する。 Next, a third embodiment of the present invention will be described with reference to FIG. The third embodiment differs from the first embodiment in that the foil film F is detected using an actuator 131 that contacts the foil film F. FIG. In the following description, members having substantially the same structure as in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.
　図９（ａ），（ｂ）に示すように、第３実施形態におけるフィルムセンサ１３０は、アクチュエータ１３１と、バネ１３２と、検知部１３３とを有している。 As shown in FIGS. 9(a) and 9(b), the film sensor 130 in the third embodiment has an actuator 131, a spring 132, and a detection section 133.
　アクチュエータ１３１は、加熱ローラ６１と供給リール３１の間に配置されている。アクチュエータ１３１は、ローラからなる接触部１３１Ａと、被検知部１３１Ｂを有しており、図９（ａ）に示す第１位置と、図９（ｂ）に示す第２位置との間を回動可能に装置本体２１に支持されている。接触部１３１Ａは、箔フィルムＦがある場合に箔フィルムと接触する部分である。被検知部１３１Ｂは、検知部１３３に検知される部分である。 The actuator 131 is arranged between the heating roller 61 and the supply reel 31 . The actuator 131 has a contact portion 131A made of a roller and a detected portion 131B, and rotates between a first position shown in FIG. 9(a) and a second position shown in FIG. 9(b). It is supported by the apparatus main body 21 as possible. The contact portion 131A is a portion that contacts the foil film F when the foil film F is present. The detected portion 131B is a portion detected by the detection portion 133 .
　バネ１３２は、アクチュエータ１３１が第２位置に位置するように付勢する圧縮バネである。検知部１３３は、被検知部１３１Ｂを検知する部分である。 The spring 132 is a compression spring that biases the actuator 131 to the second position. The detection portion 133 is a portion that detects the detected portion 131B.
　図９（ａ）に示すように、加熱ローラ６１と加熱ローラ３１の間に箔フィルムＦが有る場合、アクチュエータ１３１は、箔フィルムＦに押されて、第１位置に位置する。アクチュエータ１３１が第１位置に位置すると、検知部１３３が被検知部１３１Ｂを検知する。このとき、アクチュエータ１３１の接触部１３１Ａは、箔フィルムＦと接触して箔フィルムＦに所定のテンションを付与する。 As shown in FIG. 9(a), when the foil film F is present between the heating roller 61 and the heating roller 31, the actuator 131 is pushed by the foil film F and positioned at the first position. When the actuator 131 is positioned at the first position, the detection portion 133 detects the detected portion 131B. At this time, the contact portion 131A of the actuator 131 contacts the foil film F and applies a predetermined tension to the foil film F. As shown in FIG.
　図９（ｂ）に示すように、加熱ローラ６１と加熱ローラ３１の間に箔フィルムＦが無い場合、箔フィルムＦに押されないので、アクチュエータ１３１は、バネ１３２の付勢力によって回動し、第２位置に位置する。アクチュエータ１３１が第２位置に位置すると、検知部１３３が被検知部１３１Ｂを検知しない。 As shown in FIG. 9B, when there is no foil film F between the heating roller 61 and the heating roller 31, the actuator 131 is rotated by the urging force of the spring 132, and the actuator 131 is rotated by the biasing force of the spring 132. 2 position. When the actuator 131 is positioned at the second position, the detecting portion 133 does not detect the detected portion 131B.
　以上のように説明した第３実施例によれば、アクチュエータ１３１が箔フィルムＦに接触することで、箔フィルムＦがあることを確実に検知できる。
　また、アクチュエータ１３１が箔フィルムＦを検知するセンサと、テンションを付与する部材とを兼ねるので、部品点数を減らすことができる。 According to the third embodiment described above, the presence of the foil film F can be reliably detected by the contact of the actuator 131 with the foil film F.
Moreover, since the actuator 131 serves both as a sensor for detecting the foil film F and as a member for applying tension, the number of parts can be reduced.
