The peeling roller 42 changes the traveling direction of the foil film F that has passed through the transfer section 50, specifically between the pressure roller 51 and the heating roller 61, to be different from the conveying direction of the sheet S, thereby separating the foil film. F is peeled off from the sheet S.
　下流ガイドローラ４３は、シートＳから箔フィルムＦを剥離させるときの箔フィルムＦの角度（以下、「剥離角度」ともいう。）を規定している。ここで、剥離角度は、箔フィルムＦのうち、上流ガイドローラ４１と剥離ローラ４２の間で張架される部分と、剥離ローラ４２と下流ガイドローラ４３の間で張架される部分とのなす角である。下流ガイドローラ４３は、剥離ローラ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に案内している。 The downstream guide roller 43 defines the angle of the foil film F when peeling the foil film F from the sheet S (hereinafter also referred to as "peeling angle").

The heating roller 61 is arranged below the foil film F and is in contact with the foil film F. As shown in FIG.
　なお、本実施形態では、加熱ローラ６１を箔フィルムＦに対して接触・離間させるための接離機構７０によって加熱ローラ６１を移動させている。接離機構７０は、搬送方向において、供給リール３１と巻取リール３５の間に配置されている。接離機構７０は、カバー２２を閉じている状態においては、シートＳが転写部５０に供給されるタイミングに合わせて加熱ローラ６１を、箔フィルムＦに接触する接触位置に移動させている。また、接離機構７０は、カバー２２が開けられた場合や、転写部５０においてシートＳに箔転写を行わない場合には、加熱ローラ６１を、箔フィルムＦから離間する離間位置に位置させている。なお、接離機構７０は、後述する制御部１００で制御されることで、前述した動作を行う。 Note that in this embodiment, the heating roller 61 is moved by a contact/separation mechanism 70 for bringing the heating roller 61 into contact with/separating from the foil film F. The contact/separation mechanism 70 is arranged between the supply reel 31 and the take-up reel 35 in the transport direction. When the cover 22 is closed, the contact/separation mechanism 70 moves the heating roller 61 to the contact position where the foil film F is brought into contact with the timing when the sheet S is supplied to the transfer section 50 . Further, the contact/separation mechanism 70 positions the heating roller 61 at a separation position away from the foil film F when the cover 22 is opened or when the transfer unit 50 does not transfer the foil to the sheet S. there is The contact/separation mechanism 70 performs the operations described above under the control of the control unit 100, which will be described later.
　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 unit 50 in the transport direction, and is transported to the transfer unit 50 in a state in which the toner image on the sheet S and the foil film F are in contact. .
　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、トナー像の上に箔が転写される。 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. Foil is transferred on top.
　箔が転写された後、シートＳと箔フィルムＦは密着した状態で剥離ローラ４２まで搬送される。シートＳと箔フィルムＦが剥離ローラ４２を通過すると、箔フィルムＦの進行方向がシート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 is transferred, the sheet S and the foil film F are transported to the peeling roller 42 while being in close contact with each other. When the sheet S and the foil film F pass through the peeling roller 42, the traveling direction of the foil film F changes to a direction different from the conveying direction of the sheet S, so the foil film F is peeled off from the sheet S.
　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.

Further, when the flapper 410 is positioned at the second position, it closes the first duct 310 and opens the second duct 320 . The switching mechanism 400 is in the first state when the flapper 410 is positioned at the first position. Also, the switching mechanism 400 is in the second state when the flapper 410 is positioned at the second position.
　制御部１００は、シートＳに転写層を転写する箔転写処理を実行する場合、切替機構４００を第１状態にする。また、制御部１００は、箔転写処理を実行しない場合、切替機構４００を第２状態にする。 When executing the foil transfer process for transferring the transfer layer to the sheet S, the control unit 100 sets the switching mechanism 400 to the first state. Further, when the foil transfer process is not executed, the control section 100 puts the switching mechanism 400 in the second state.
　次に、切替機構４００の動作について詳細に説明する。
　制御部１００は、箔転写処理を開始するための転写指令を受けると、加熱ローラ６１を加圧ローラ５１に圧接する処理を行うとともに、ロック部材９１をロック位置に位置させる処理を行う。また、この際、制御部１００は、各ファン２１０，２２０の駆動を行うとともに、フラッパー４１０を第１位置に位置させる処理を行う。これにより、図３に示すように、箔転写処理中においては、第１ファン２１０からダクト３００内に取り込まれた空気は、第１ダクト３１０を通って、加熱ローラ６１と剥離ローラ４２の間の箔フィルムＦに向けて流れる。そのため、箔転写処理中において、シートＳからの箔フィルムＦの剥離性を向上させることができる。 Next, the operation of switching mechanism 400 will be described in detail.
When the control unit 100 receives a transfer command for starting the foil transfer process, the control unit 100 performs a process of pressing the heating roller 61 against the pressure roller 51 and a process of positioning the lock member 91 at the lock position. Further, at this time, the control unit 100 drives the fans 210 and 220 and also performs processing for positioning the flapper 410 at the first position. As a result, as shown in FIG. 3, during the foil transfer process, the air taken into the duct 300 from the first fan 210 passes through the first duct 310 and flows between the heating roller 61 and the peeling roller 42. It flows towards the foil film F. Therefore, the peelability of the foil film F from the sheet S can be improved during the foil transfer process.
　箔転写処理が終了すると、制御部１００は、図４に示すように、加熱ローラ６１を加圧ローラ５１から離間する処理を行うとともに、各ファン２１０，２２０を駆動させたまま、フラッパー４１０を第１位置から第２位置に移動させる処理を行う。これにより、箔転写終了後においては、第１ファン２１０からダクト３００内に取り込まれた空気は、第２ダクト３２０を通って、加圧ローラ５１と加熱ローラ６１に向けて流れる。そのため、箔転写処理の終了後は、箔転写装置１内の温度を迅速に下げることができる。 When the foil transfer process is completed, the controller 100 separates the heating roller 61 from the pressure roller 51 as shown in FIG. A process of moving from the first position to the second position is performed. As a result, after the foil transfer is completed, the air taken into the duct 300 from the first fan 210 passes through the second duct 320 and flows toward the pressure roller 51 and the heating roller 61 . Therefore, after the foil transfer process is completed, the temperature inside the foil transfer device 1 can be quickly lowered.
　箔転写装置１内の温度が所定値未満になると、制御部１００は、ロック部材９１をロック位置から解除位置に移動させる。これにより、ユーザは、カバー２２を開けることが可能となる。なお、各ファン２１０，２２０を停止するタイミングは、箔転写装置１内の温度が所定値未満になったときであってもよいし、箔転写処理の終了から所定時間の経過後であってもよい。 When the temperature inside the foil transfer device 1 falls below a predetermined value, the control section 100 moves the lock member 91 from the lock position to the release position. This allows the user to open the cover 22 . The timing for stopping the fans 210 and 220 may be when the temperature inside the foil transfer apparatus 1 becomes less than a predetermined value, or after a predetermined time has passed since the end of the foil transfer process. good.
　以上によれば、本実施形態において以下のような効果を得ることができる。
　箔転写時において切替機構４００を第１状態とすることで、シートＳからの箔フィルムＦの剥離性を向上させることができる。また、非箔転写時において切替機構４００を第２状態とすることで、加熱ローラ６１等の温度を迅速に下げることができる。 According to the above, the following effects can be obtained in this embodiment.
By setting the switching mechanism 400 to the first state during foil transfer, the peelability of the foil film F from the sheet S can be improved. Further, by setting the switching mechanism 400 to the second state during non-foil transfer, the temperature of the heating roller 61 and the like can be rapidly lowered.
　面積の大きな第２排出口Ｈｏ２によって加熱ローラ６１および加圧ローラ５１の広い範囲に空気を当てることができるので、加熱ローラ６１および加圧ローラ５１を効率的に冷却することができる。 The large-area second discharge port Ho2 allows air to hit a wide range of the heating roller 61 and the pressure roller 51, so that the heating roller 61 and the pressure roller 51 can be efficiently cooled.
　箔転写を実行していないときには、切替機構４００が第２状態となることで、加熱ローラ６１等が効率よく冷却されて、温度センサＳａの検知温度を所定値未満まで迅速に下げることができるので、カバー２２を開けることができない期間を短くすることができる。 When the foil transfer is not being performed, the switching mechanism 400 is in the second state, so that the heating roller 61 and the like are efficiently cooled, and the temperature detected by the temperature sensor Sa can be quickly lowered to less than the predetermined value. , the period during which the cover 22 cannot be opened can be shortened.
　次に、本発明の第２実施形態について、適宜図面を参照しながら詳細に説明する。なお、本実施形態は、前記した第１実施形態の一部の構造を変更したものであるため、第１実施形態と同様の構成要素や処理については、同一符号を付し、その説明を省略することとする。 Next, a second embodiment of the present invention will be described in detail with reference to the drawings as appropriate. In addition, since the structure of the present embodiment is partially modified from the structure of the first embodiment, the same components and processes as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. I decided to.
　図６に示すように、第２実施形態に係る箔転写装置１Ａは、第１実施形態とは異なる構造のダクト５００を備えている。また、第２実施形態では、フラッパー４１０の配置が第１実施形態とは異なっている。 As shown in FIG. 6, a foil transfer device 1A according to the second embodiment includes a duct 500 having a structure different from that of the first embodiment. Also, in the second embodiment, the arrangement of the flapper 410 is different from that in the first embodiment.
　ダクト５００は、第１実施形態のように分岐されておらず、第１ファン２１０から、剥離ローラ４２の搬送方向上流側に向けて延びている。ダクト５００は、第１実施形態とは多少構造が異なる上流側流路５１１および下流側流路５１２を有する。 The duct 500 is not branched unlike the first embodiment, and extends from the first fan 210 toward the upstream side in the conveying direction of the peeling roller 42 . The duct 500 has an upstream flow path 511 and a downstream flow path 512 that are slightly different in structure from the first embodiment.
　上流側流路５１１の送風方向における上流側部分は、加圧ローラ５１に向けて分岐していない。上流側流路５１１の送風方向の下流端に位置する下流側開口Ｈ１１は、剥離ローラ４２の搬送方向上流側に位置する箔フィルムＦに向けて開口するとともに、加圧ローラ５１に向けて開口する。なお、上流側流路５１１の形状は、第１実施形態の上流側流路３１１の形状と略同様となっている。下流側開口Ｈ１１は、フラッパー４１０が通過可能となっている。 The upstream portion of the upstream flow path 511 in the blowing direction does not branch toward the pressure roller 51 . The downstream opening H11 located at the downstream end of the upstream flow path 511 in the blowing direction opens toward the foil film F located upstream in the conveying direction of the peeling roller 42 and toward the pressure roller 51 . . The shape of the upstream channel 511 is substantially the same as the shape of the upstream channel 311 of the first embodiment. The flapper 410 can pass through the downstream opening H11.
　下流側流路５１２は、送風方向の上流端に位置する上流側開口Ｈ２１が第１実施形態の下流側流路３１２と異なるだけで、その他の構造は、第１実施形態の下流側流路３１２と略同様の構造となっている。上流側開口Ｈ２１は、フラッパー４１０が通過可能な大きさに形成されている。 The downstream flow path 512 differs from the downstream flow path 312 of the first embodiment only in the upstream opening H21 located at the upstream end in the blowing direction, and the rest of the structure is the same as that of the downstream flow path 312 of the first embodiment. It has almost the same structure as The upstream opening H21 is sized to allow the flapper 410 to pass therethrough.
　下流側流路５１２の送風方向の下流端に位置する下流側開口Ｈ３には、第１実施形態と同様の排出口形成部材３１３が覆うように配置されている。上流側流路５１１の下流側開口Ｈ１１と加圧ローラ５１の間には、第２排出口形成部材５１３が下流側開口Ｈ１１の一部を覆うように配置されている。 The downstream opening H3 located at the downstream end of the downstream flow path 512 in the blowing direction is covered with the outlet forming member 313 similar to that of the first embodiment. Between the downstream opening H11 of the upstream flow path 511 and the pressure roller 51, the second outlet forming member 513 is arranged so as to partially cover the downstream opening H11.
　第２排出口形成部材５１３は、図８に示すように、下流側流路５１２内の空気を排出する第２排出口Ｈｏ２１を有する部材である。第２排出口Ｈｏ２１は、複数の孔Ｈ５からなる。各孔Ｈ５は、搬送方向に長いスリット状に形成されている。第２排出口Ｈｏ２１は、加圧ローラ５１に向けて開口する（図６参照）。 The second discharge port forming member 513 is a member having a second discharge port Ho21 for discharging the air in the downstream channel 512, as shown in FIG. The second outlet Ho21 consists of a plurality of holes H5. Each hole H5 is formed in a slit shape elongated in the transport direction. The second outlet Ho21 opens toward the pressure roller 51 (see FIG. 6).
　第２排出口Ｈｏ２１を構成する孔Ｈ５は、搬送方向の長さが、図５（ｂ）に示す第１排出口Ｈｏ１を構成する孔Ｈ４よりも小さいが、幅方向の長さが、孔Ｈ４よりも大きい。また、複数の孔Ｈ５のピッチは、複数の孔Ｈ４のピッチよりも小さい。これにより、複数の孔Ｈ５の面積の総和は、複数の孔Ｈ４の面積の総和よりも大きくなっている。つまり、第２実施形態でも、第２排出口Ｈｏ２１の面積は、第１排出口Ｈｏ１の面積よりも大きい。 The hole H5 forming the second discharge port Ho21 has a length in the transport direction smaller than that of the hole H4 forming the first discharge port Ho1 shown in FIG. greater than Also, the pitch of the plurality of holes H5 is smaller than the pitch of the plurality of holes H4. Thereby, the total area of the plurality of holes H5 is larger than the total area of the plurality of holes H4. That is, also in the second embodiment, the area of the second outlet Ho21 is larger than the area of the first outlet Ho1.
　図６に示すように、フラッパー４１０のシャフト４１１は、下流側流路５１２の上流側開口Ｈ２１付近に配置されている。フラッパー４１０は、図６に示す第１位置と、図７に示す第２位置との間で回動可能となっている。 As shown in FIG. 6, the shaft 411 of the flapper 410 is arranged near the upstream opening H21 of the downstream channel 512 . The flapper 410 is rotatable between a first position shown in FIG. 6 and a second position shown in FIG.
　フラッパー４１０は、第１位置に位置するとき、排出口形成部材３１３の第１排出口Ｈｏ１を開放し、第２排出口形成部材５１３の第２排出口Ｈｏ２１を閉じる。また、フラッパー４１０は、第２位置に位置するとき、第１排出口Ｈｏ１を閉じ、第２排出口Ｈｏ２１を開放する。以上のような第２実施形態でも、第１実施形態と同様の効果を得ることができる。 The flapper 410 opens the first outlet Ho1 of the outlet forming member 313 and closes the second outlet Ho21 of the second outlet forming member 513 when positioned at the first position. Further, when the flapper 410 is positioned at the second position, it closes the first discharge port Ho1 and opens the second discharge port Ho21. The same effects as those of the first embodiment can be obtained in the second embodiment as described above.
　次に、本発明の第３実施形態について、適宜図面を参照しながら詳細に説明する。なお、本実施形態は、前記した第２実施形態の一部の構造を変更したものであるため、第２実施形態と同様の構成要素や処理については、同一符号を付し、その説明を省略することとする。 Next, a third embodiment of the present invention will be described in detail with reference to the drawings as appropriate. In addition, since the present embodiment partially changes the structure of the above-described second embodiment, the same components and processes as those of the second embodiment are denoted by the same reference numerals, and the description thereof is omitted. I decided to.
　図９に示すように、第３実施形態の箔転写装置１Ｂは、第２実施形態とは異なる構造のダクト６００を備えている。ダクト６００は、第２実施形態の上流側流路５１１と略同様の構造であるが、送風方向の下流端に位置する下流側開口Ｈ１２が、第２実施形態の下流側開口Ｈ１１よりも箔フィルムＦから離れた位置に配置されている。 As shown in FIG. 9, the foil transfer device 1B of the third embodiment has a duct 600 having a structure different from that of the second embodiment. The duct 600 has substantially the same structure as the upstream flow path 511 of the second embodiment, but the downstream opening H12 located at the downstream end in the blowing direction is closer to the foil film than the downstream opening H11 of the second embodiment. It is located away from F.
　第３実施形態では、フラッパー４１０は、ダクト６００内に配置されておらず、ダクト６００の下流側開口Ｈ１２の送風方向下流側に配置されている。フラッパー４１０は、図９に示す第１位置と、図１０に示す第２位置との間で回動可能となっている。フラッパー４１０は、第１位置に位置するとき、加熱ローラ６１と剥離ローラ４２の間に位置する箔フィルムＦに向けて空気を案内する。また、フラッパー４１０は、第２位置に位置するとき、加圧ローラ５１に向けて空気を案内する。以上のような第３実施形態でも、第１実施形態と同様の効果を得ることができる。 In the third embodiment, the flapper 410 is not arranged inside the duct 600, but is arranged downstream of the downstream opening H12 of the duct 600 in the blowing direction. The flapper 410 is rotatable between a first position shown in FIG. 9 and a second position shown in FIG. The flapper 410 guides air toward the foil film F positioned between the heating roller 61 and the peel roller 42 when positioned at the first position.
