Description

本発明は、シート体を並列に搬送する搬送装置、及びこの搬送装置により搬送されるカットシート状の記録材料(シート体)に画像記録を行う画像記録装置に関するものである。   The present invention relates to a conveyance device that conveys sheet bodies in parallel, and an image recording apparatus that records an image on a cut sheet-like recording material (sheet body) conveyed by the conveyance device.

例えば、写真プリンタでは、カットシート状の感光材料を搬送経路に複数設けられた搬送ローラ対を用いて副走査方向に挟持搬送しながら、記録光を副走査方向と直交する主走査方向に走査して、いわゆる走査露光による画像記録を行っている。この写真プリンタには、単位時間当たりの処理能力(枚数)を上げるために、露光前に感光材料の振り分けを行い、主走査方向に複数の感光材料を並列に搬送させながら同時露光を行うものが多い。   For example, a photographic printer scans recording light in the main scanning direction perpendicular to the sub-scanning direction while sandwiching and transporting a cut sheet-like photosensitive material in the sub-scanning direction using a plurality of transport roller pairs provided in the transport path. Thus, image recording by so-called scanning exposure is performed. In this photographic printer, in order to increase the processing capacity (number of sheets) per unit time, a photosensitive material is distributed before exposure, and a plurality of photosensitive materials are conveyed in parallel in the main scanning direction and simultaneously exposed. Many.

高品質な写真プリントを得るには、感光材料が適正な位置及び向きで露光される必要があるが、カットシート状の感光材料は搬送中に傾いて、いわゆるスキューした状態になってしまうことが多い。感光材料が傾いた状態のまま露光されると、感光材料に対して画像が斜めに記録されてしまうため、写真プリントの品質が著しく低下してしまう。そのため、特許文献1に記載されているように、振り分け用の搬送ローラ対によって各列への振り分けを行う際に、感光材料を挟持した状態で、この搬送ローラ対を感光材料の記録面に対して垂直な任意の回転軸で回転させることによって、感光材料の傾きを補正する、いわゆるチルトレジストを行っている写真プリンタがある。   In order to obtain a high-quality photographic print, the photosensitive material needs to be exposed at an appropriate position and orientation. However, the cut sheet-shaped photosensitive material may be tilted during conveyance and become a so-called skewed state. Many. If the photosensitive material is exposed while being tilted, an image is recorded obliquely with respect to the photosensitive material, so that the quality of the photographic print is significantly deteriorated. Therefore, as described in Patent Document 1, when sorting to each row by a sorting transport roller pair, the transport roller pair is placed on the recording surface of the photosensitive material while holding the photosensitive material. There are photographic printers that perform so-called tilt registration, in which the tilt of the photosensitive material is corrected by rotating it around an arbitrary vertical rotation axis.

特開2003−222954号公報(第5頁)JP 2003-222954 A (page 5)

特許文献1に記載されている写真プリンタでは、その処理能力を上げるために、露光前に感光材料の振り分けを行って並列搬送及び同時露光を行うようにしているが、さらなる処理能力の向上を図るために、最初から搬送経路に複数の感光材料を並列に供給して、振り分けを行うことなく、並列搬送及び同時露光を行うことが要請されている。このように、感光材料が並列供給及び搬送されている場合には、特許文献1に記載されているような傾き補正を単列で行ってから振り分けを行う方法では対応できない。   In the photographic printer described in Patent Document 1, in order to increase the processing capacity, the photosensitive material is distributed before exposure to perform parallel conveyance and simultaneous exposure. However, the processing capacity is further improved. Therefore, it is required to supply a plurality of photosensitive materials in parallel to the transport path from the beginning, and perform parallel transport and simultaneous exposure without performing sorting. As described above, when the photosensitive materials are supplied and transported in parallel, it is not possible to cope with the method of performing sorting after performing the tilt correction as described in Patent Document 1 in a single row.

また、チルトレジスト以外の傾き補正方法として、挟持状態の搬送ローラ対のローラ間に感光材料の先端辺を当接させて傾きを補正する、いわゆるトップレジストを行う方法がある。トップレジストを行う場合には、先端辺を当接させる搬送ローラ対の長さを長くすることで感光材料の並列搬送に対応することは可能であるが、感光材料を当接させている間は、搬送を停止する必要があるため、処理能力が低下してしまう。   As a tilt correction method other than the tilt registration, there is a so-called top registration method in which the front end side of the photosensitive material is brought into contact with the rollers of the sandwiched conveying roller pair to correct the tilt. When performing top registration, it is possible to cope with parallel conveyance of photosensitive material by increasing the length of the pair of conveyance rollers that abut the tip side. Since the conveyance needs to be stopped, the processing capacity is lowered.

本発明は上記問題を解決するためのものであり、並列搬送されている感光材料の傾きを効率よく補正できるようにした搬送装置、及びこの搬送装置を備えた画像記録装置を提供することを目的とする。   The present invention has been made to solve the above-described problems, and it is an object of the present invention to provide a transport apparatus capable of efficiently correcting the inclination of photosensitive materials being transported in parallel, and an image recording apparatus including the transport apparatus.

図1は本発明を実施した写真プリンタ10を示した概略図である。写真プリンタ10は、2列同時に供給されたカットシート状の感光材料を2列搬送及び同時露光して写真プリントを出力するものであり、図1に示すように、マガジン12,13、カッタ15,16、裏印字装置18、傾き補正装置19、露光装置21、現像装置22などから構成される。   FIG. 1 is a schematic view showing a photographic printer 10 embodying the present invention. The photographic printer 10 conveys and simultaneously exposes two sheets of cut sheet-like photosensitive material supplied simultaneously, and outputs a photographic print. As shown in FIG. 1, the magazines 12 and 13, the cutter 15, 16, a back printing device 18, an inclination correction device 19, an exposure device 21, a developing device 22, and the like.

マガジン12,13は、写真プリンタ10内の所定の位置に装填され、それぞれ、感光材料である長尺の感光記録紙24をロール状に巻き取った記録紙ロール25が収納されている。また、マガジン12,13の給紙口近傍には給紙ローラ対27が備えられ、図示しない給紙用モータによって給紙ローラ対27が回転すると、記録紙ロール25から感光記録紙11が引き出され、カッタ15,16へ向けて送り出される。   The magazines 12 and 13 are loaded at predetermined positions in the photographic printer 10 and store recording paper rolls 25 each of which is a roll of a long photosensitive recording paper 24 that is a photosensitive material. Further, a pair of paper feed rollers 27 is provided in the vicinity of the paper feed opening of the magazines 12 and 13, and when the paper feed roller pair 27 is rotated by a paper feed motor (not shown), the photosensitive recording paper 11 is pulled out from the recording paper roll 25. , Sent to the cutters 15 and 16.

カッタ15,16は、それぞれ感光記録紙24の搬送経路を挟んで配置され、感光記録紙24の先端がカッタ15,16より所定の長さだけ送り出されると、図示しないカッタ駆動機構が作動して、感光記録紙24を切断して所定長の記録紙シート28(図2参照)とする。なお、カッタを2つ設ける代わりに、単一のカッタを裏印字装置18の近傍に配置してもよい。   The cutters 15 and 16 are respectively arranged with the conveyance path of the photosensitive recording paper 24 interposed therebetween. When the leading end of the photosensitive recording paper 24 is fed out from the cutters 15 and 16 by a predetermined length, a cutter driving mechanism (not shown) is activated. Then, the photosensitive recording paper 24 is cut into a recording paper sheet 28 (see FIG. 2) having a predetermined length. Instead of providing two cutters, a single cutter may be arranged in the vicinity of the back printing device 18.

カッタ15,16おいてカットされた記録紙シート28は、複数の搬送ローラ対30,31によって図中点線で示した搬送経路に沿って裏印字装置18、傾き補正装置19、露光装置21、現像装置22の順に搬送される。この際に、各マガジン12,13から供給される記録紙シート28が並列になるように、各カッタ15,16から裏印字装置18までの搬送距離や各搬送ローラ対30の搬送速度などを調整しておく。なお、本実施形態において、マガジン12,13は、図中鉛直方向に並列に配置されているが、その代わりに、記録紙シート28の幅方向に並列に配置してもよい。また、マガジンを2つ配置する代わりに、同一マガジン内に記録紙ロール25を複数セットするようにしてもよい。裏印字装置18では、並列(2列)搬送された記録紙シート28の裏面(記録面と反対側の面)に、それぞれフイルムIDやコマ番号などの必要情報が印字される。   The recording paper sheet 28 cut by the cutters 15 and 16 is printed on the back printing device 18, the inclination correction device 19, the exposure device 21, and the development along a conveyance path indicated by a dotted line in the figure by a plurality of conveyance roller pairs 30 and 31. It is conveyed in the order of the device 22. At this time, the conveyance distance from each cutter 15, 16 to the back printing device 18 and the conveyance speed of each conveyance roller pair 30 are adjusted so that the recording paper sheets 28 supplied from the respective magazines 12, 13 are arranged in parallel. Keep it. In the present embodiment, the magazines 12 and 13 are arranged in parallel in the vertical direction in the figure, but instead, they may be arranged in parallel in the width direction of the recording paper sheet 28. Further, instead of arranging two magazines, a plurality of recording paper rolls 25 may be set in the same magazine. The back printing device 18 prints necessary information such as a film ID and a frame number on the back surface (surface opposite to the recording surface) of the recording paper sheets 28 conveyed in parallel (two rows).

裏印字がなされた各記録紙シート28は、搬送ローラ対31によって傾き補正装置19に2列搬送される。傾き補正装置19は、詳しくは後述するが、各列毎の記録紙シート28の搬送方向に対する傾きを検出するとともに、各記録紙シート28の両側端部が搬送経路上を搬送される距離を変えることによって、2列同時に傾き(スキュー)の補正を行う。傾き補正された各記録紙シート28は、露光装置21に搬送される。   Each recording paper sheet 28 on which reverse printing has been performed is conveyed in two rows to the inclination correction device 19 by a conveying roller pair 31. As will be described in detail later, the inclination correction device 19 detects the inclination of the recording paper sheet 28 in each row with respect to the conveyance direction, and changes the distance that both end portions of each recording paper sheet 28 are conveyed on the conveyance path. Thus, the inclination (skew) is corrected simultaneously for two columns. Each of the recording paper sheets 28 whose inclination has been corrected is conveyed to the exposure device 21.

露光装置21は、この露光装置21と裏印字装置18との間のシート搬送距離が、少なくともこの写真プリンタ10において搬送される最長の記録紙シート28の長さよりも長くなるような位置に配置されている。これにより、裏印字中に記録紙シート28の搬送速度が変動して、露光むらが発生するのを防止できる。露光装置21には、周知のレーザプリンタと画像メモリとが備えられている。画像メモリには、図示しないフイルムスキャナで読み取られ、或いは図示しないメモリカード等の記録媒体からの画像データを記憶する。レーザプリンタは、記録する画像に対応して強度変調されたレーザ光を搬送方向(副走査方向)と直交する主走査方向に走査して、記録紙シート28を2列同時に露光する。露光済みの記録紙シート28は、現像装置22に送られる。現像装置22において、発色現像・定着・洗浄の各処理が行われた後、乾燥処理が施され、写真プリントとして写真プリンタ10の外部へ送り出される。   The exposure device 21 is disposed at a position where the sheet conveyance distance between the exposure device 21 and the back printing device 18 is at least longer than the length of the longest recording paper sheet 28 conveyed in the photographic printer 10. ing. As a result, it is possible to prevent unevenness in exposure due to fluctuations in the conveyance speed of the recording paper sheet 28 during backside printing. The exposure device 21 includes a known laser printer and an image memory. The image memory stores image data read by a film scanner (not shown) or from a recording medium such as a memory card (not shown). The laser printer scans the laser beam, which has been intensity-modulated corresponding to the image to be recorded, in the main scanning direction orthogonal to the transport direction (sub-scanning direction), and exposes the recording paper sheets 28 in two rows simultaneously. The exposed recording paper sheet 28 is sent to the developing device 22. In the developing device 22, color development / fixing / washing processes are performed, and then a drying process is performed, which is sent out of the photographic printer 10 as a photographic print.

傾き補正装置19は、図2に示すように、搬送系路上に主走査方向に沿って並列に配置され、2列搬送されている記録紙シート28をそれぞれ挟持搬送しながら傾き補正を行う第1レジスト用ローラ対35及び第2レジスト用ローラ対36と、これらのシート搬送方向上流側であって、搬送経路の主走査方向の略中央部に配置された第3レジスト用ローラ対37と、各レジスト用ローラ対35,36,37のシート搬送方向上流側に並列に配置されたフォトセンサ38,39とから構成される。また、第1及び第2レジスト用ローラ対35,36の搬送方向下流側には、傾き補正された各記録紙シート28を露光装置21へ搬送するための搬送ローラ対40が配置されている。なお、裏印字中に傾き補正されないように、この傾き補正装置19は、裏印字装置18から、写真プリンタ10において裏印字される最大文字長さ以上の距離だけ下流側に配置されている。   As shown in FIG. 2, the tilt correction device 19 is arranged in parallel along the main scanning direction on the transport path and performs tilt correction while sandwiching and transporting the recording paper sheets 28 transported in two rows. A pair of registration rollers 35 and a pair of second registration rollers 36, and a third pair of registration rollers 37 disposed upstream of these sheet conveyance directions and substantially in the center of the conveyance path in the main scanning direction; The photosensors 38 and 39 are arranged in parallel on the upstream side of the registration roller pair 35, 36, and 37 in the sheet conveying direction. Further, on the downstream side in the transport direction of the first and second registration roller pairs 35, 36, a transport roller pair 40 for transporting each recording paper sheet 28 whose tilt has been corrected to the exposure device 21 is disposed. Note that the inclination correction device 19 is arranged downstream from the back printing device 18 by a distance equal to or longer than the maximum character length to be back printed in the photographic printer 10 so that the inclination is not corrected during the back printing.

第3レジスト用ローラ対37は、端数処理時などに単列搬送される記録紙シート28や、2列搬送できないサイズの大きい記録紙シート28に傾き補正を行うものである。なお、第3レジスト用ローラ対37による傾き補正が行い易いように、端数処理時やサイズの大きい記録紙シート28を搬送する場合には、搬送経路上にガイドレールなどを設けるなどして、記録紙シート28を搬送経路の略中央部に移動させておく。なお、本実施形態では、第3レジスト用ローラ対37を第1、第2レジスト用ローラ対35,36の搬送方向上流側に配置したが、これらの下流側に配置してもよい。   The third registration roller pair 37 corrects the inclination of the recording paper sheet 28 that is conveyed in a single row during fraction processing or the like and the recording paper sheet 28 that is large and cannot be conveyed in two rows. In order to facilitate the inclination correction by the third registration roller pair 37, when the recording paper sheet 28 having a large size is conveyed at the time of fraction processing, a recording medium such as a guide rail is provided on the conveyance path. The paper sheet 28 is moved to the approximate center of the transport path. In the present embodiment, the third registration roller pair 37 is disposed on the upstream side in the transport direction of the first and second registration roller pairs 35 and 36, but may be disposed on the downstream side thereof.

次に、図3を用いて第1〜第3レジスト用ローラ対35,36,37の機構について説明する。なお、各レジスト用ローラ対35,36,37は同一構造であるので、ここでは第1レジスト用ローラ対35についてのみ説明する。また、第2及び第3レジスト用ローラ対36,37において、第1レジスト用ローラ対35と同一部材には同一符号を付して、その説明は省略する。   Next, the mechanism of the first to third registration roller pairs 35, 36, and 37 will be described with reference to FIG. Since each registration roller pair 35, 36, 37 has the same structure, only the first registration roller pair 35 will be described here. In the second and third registration roller pairs 36 and 37, the same members as those in the first registration roller pair 35 are denoted by the same reference numerals, and the description thereof is omitted.

図3に示すように、第1レジスト用ローラ対35は、周知の図示しない搬送モータによって回転駆動されるキャプスタンローラ41と、このキャプスタンローラ41に圧接するピンチローラ42と、各ローラ41,42の両端部をそれぞれ副走査方向と平行な方向に移動させる第1移動機構43a、第2移動機構43bとから構成される。   As shown in FIG. 3, the first registration roller pair 35 includes a capstan roller 41 that is rotationally driven by a well-known transport motor (not shown), a pinch roller 42 that is in pressure contact with the capstan roller 41, and each roller 41, The first moving mechanism 43a and the second moving mechanism 43b are configured to move both end portions of 42 in a direction parallel to the sub-scanning direction.

第1移動機構43aは、各ローラ41,42をそれぞれ回転自在に保持する軸受け43a,43bと、記録紙シート28(図2参照)の記録面に垂直な回転軸47を介して、軸受け43a,43bを回転自在に保持する下部保持部材49a及び上部保持部材49bと、各保持部材49a,49bに形成され、副走査方向に対して平行なねじ孔(図示せず)と、各ねじ孔に螺合するボールねじ50a,50bと、各ボールねじ50a,50bの端部を回転自在に把持するチャック51a,51bと、各チャック51a,51bを介してボールねじ50a,50bを回転駆動するモータ53とから構成される。なお、モータ53を回転させた際に、ボールねじ50a,50bの回転方向と回転数とが等しくなるように、モータ53とチャック51a,51bとの間のギヤ数やギアの歯数などを調整しておく。つまり、モータ53を回転させたときに、各保持部材49a,49bを同一方向に同一移動量だけ移動させるようにしておく。   The first moving mechanism 43a includes bearings 43a, 43b that rotatably support the rollers 41, 42, and a rotation shaft 47 that is perpendicular to the recording surface of the recording paper sheet 28 (see FIG. 2). The lower holding member 49a and the upper holding member 49b that rotatably hold 43b, screw holes (not shown) formed in the holding members 49a and 49b, parallel to the sub-scanning direction, and screws in the screw holes. The ball screws 50a and 50b to be joined together, chucks 51a and 51b for gripping the end portions of the ball screws 50a and 50b, and a motor 53 for rotating the ball screws 50a and 50b via the chucks 51a and 51b. Consists of When the motor 53 is rotated, the number of gears and the number of gear teeth between the motor 53 and the chucks 51a and 51b are adjusted so that the rotation direction and the rotation number of the ball screws 50a and 50b become equal. Keep it. That is, when the motor 53 is rotated, the holding members 49a and 49b are moved in the same direction by the same movement amount.

第2移動機構43bは、第1移動機構43aと同一の機構であり、ボールねじ50a,50bを回転駆動するモータ54以外は、同一符号を付してその説明は省略する。また、第2及び第3レジスト用ローラ対36,37にも、同じ構成の第1及び第2移動機構55a,55b、第1及び第2移動機構56a,56bが設けられている(図2参照)。なお、各移動機構としては、各レジスト用ローラ対35〜37の両端部をそれぞれ副走査方向に対して平行な方向に移動できればよいので、エアシリンダー、リードスクリュウ、タイミングベルトなどを用いたアクチュエータを使用してもよい。   The second moving mechanism 43b is the same mechanism as the first moving mechanism 43a. The second moving mechanism 43b is given the same reference numeral except for the motor 54 that rotationally drives the ball screws 50a and 50b, and the description thereof is omitted. The second and third registration roller pairs 36 and 37 are also provided with first and second moving mechanisms 55a and 55b and first and second moving mechanisms 56a and 56b having the same configuration (see FIG. 2). ). Each moving mechanism only needs to be able to move both end portions of each of the registration roller pairs 35 to 37 in a direction parallel to the sub-scanning direction. Therefore, an actuator using an air cylinder, a lead screw, a timing belt, or the like is used. May be used.

各ローラ41,42の両端に設けられた軸受け43a,43bは、それぞれ各保持部材49a,49bに対して回動自在に保持されている。従って、モータ53,54を個々に制御して、各ローラ41,42の両端部をそれぞれ異なる方向に移動させるか、或いは移動量を変えて同一方向に移動させることによって、各記録紙シート28の両側端部が搬送経路上を搬送される距離が変わるので、各ローラ41,42の搬送方向に対する傾き量を任意に調整することができる。つまり、記録紙シート28を挟持した状態で、その先端辺が主走査方向と平行になるようにモータ53,54を回転駆動することにより、記録紙シート28を傾き補正することができる。   Bearings 43a and 43b provided at both ends of the rollers 41 and 42 are rotatably held with respect to the holding members 49a and 49b, respectively. Accordingly, by controlling the motors 53 and 54 individually, the both ends of the rollers 41 and 42 are moved in different directions or moved in the same direction by changing the movement amount, so that each recording paper sheet 28 is moved. Since the distance at which both end portions are transported on the transport path changes, the amount of inclination of the rollers 41 and 42 with respect to the transport direction can be arbitrarily adjusted. That is, the recording paper sheet 28 can be tilt-corrected by rotationally driving the motors 53 and 54 so that the leading edge of the recording paper sheet 28 is parallel to the main scanning direction.

上述の移動機構を設ける代わりに、記録面に垂直な一つの回転軸、例えば、レジスト用ローラ対35のいずれか一方の端部を回転軸として、傾き補正を行ってもよいが、傾き補正前の各記録紙シート28の傾き量の違いなどによって、傾き補正後の各先端辺の位置がずれてしまう。従って、2列搬送されている各記録紙シート28の傾き量が異なっているときは、傾き補正後に各記録紙シート28の先端辺の位置を揃えないと、同時露光の制御が困難になる。本実施形態では、各ローラ41,42の両端部をそれぞれ副走査方向と平行な方向に移動させているため、傾き補正を行う際に、先端辺の位置を任意に調整することができる。つまり、傾き補正と同時に各記録紙シート28の先端辺の位置を揃えることができる。   Instead of providing the moving mechanism described above, tilt correction may be performed using one rotation axis perpendicular to the recording surface, for example, one end of the registration roller pair 35 as the rotation axis. Due to the difference in the inclination amount of each recording paper sheet 28, the position of each leading edge after the inclination correction is shifted. Accordingly, when the amounts of inclination of the recording paper sheets 28 conveyed in two rows are different, it is difficult to control the simultaneous exposure unless the positions of the leading edges of the recording paper sheets 28 are aligned after the inclination correction. In the present embodiment, since both end portions of each of the rollers 41 and 42 are moved in the direction parallel to the sub-scanning direction, the position of the front end side can be arbitrarily adjusted when performing tilt correction. That is, the position of the leading edge of each recording paper sheet 28 can be aligned simultaneously with the tilt correction.

第1レジスト用ローラ対35に搬送されてくる記録紙シート28の傾き量は、フォトセンサ38,39によって検出される。各フォトセンサ38,39は、それぞれ記録紙シート28の搬送経路を挟み込むように配置された発光素子と受光素子とからなる。各フォトセンサ38,39の間隔は、写真プリンタ10において搬送される最小幅の記録紙シート28の先端辺を検出できるように調整されている。各フォトセンサ38,39の検出信号は、写真プリンタ10のコントローラ57に送られる。コントローラ57は、記録紙シート28の先端辺がフォトセンサ38及びフォトセンサ39に検出される際の通過時間差情報と、各フォトセンサ38,39の間隔と、記録紙シート28の搬送速度とから記録紙シート28の傾き量や、いずれの方向に傾いているかを検出する。また、コントローラ57は、同時に第2レジスト用ローラ対36(図2参照)に搬送されてくる記録紙シート28の傾き量も同様にして検出する。   The amount of inclination of the recording paper sheet 28 conveyed to the first registration roller pair 35 is detected by photosensors 38 and 39. Each of the photosensors 38 and 39 includes a light emitting element and a light receiving element arranged so as to sandwich the conveyance path of the recording paper sheet 28. The interval between the photosensors 38 and 39 is adjusted so that the leading edge of the recording paper sheet 28 having the minimum width conveyed in the photographic printer 10 can be detected. Detection signals from the photosensors 38 and 39 are sent to the controller 57 of the photographic printer 10. The controller 57 records from the passing time difference information when the leading edge of the recording paper sheet 28 is detected by the photosensor 38 and the photosensor 39, the interval between the photosensors 38 and 39, and the conveyance speed of the recording paper sheet 28. It detects the amount of inclination of the paper sheet 28 and in which direction it is inclined. In addition, the controller 57 similarly detects the amount of inclination of the recording paper sheet 28 simultaneously conveyed to the second registration roller pair 36 (see FIG. 2).

コントローラ57は、これらの算出結果に基づいて、図2及び図3に示すように、2列搬送されている記録紙シート28を傾き補正し、尚且つ傾き補正後の各記録紙シート28の先端辺の位置が揃うように、レジスト用ローラ対35,36の各移動機構43a,43b,55a,55b(モータ53,54の回転数及び回転方向)を制御する。   Based on these calculation results, the controller 57 corrects the inclination of the recording paper sheets 28 conveyed in two rows as shown in FIGS. 2 and 3, and the front end of each recording paper sheet 28 after the inclination correction is performed. The moving mechanisms 43a, 43b, 55a, and 55b of the registration roller pair 35 and 36 (the rotation speed and the rotation direction of the motors 53 and 54) are controlled so that the sides are aligned.

傾き補正作業時に、記録紙シート28が他の搬送ローラ対によって挟持されていると、レジスト作業ができなくなってしまう。そのため、各レジスト用ローラ対35,36,37の挟持状態を解除する解除機構(図示せず)を設ける。解除機構の例として、カムやバネ、ソレノイド等からなるシフト機構を用いて、ピンチローラ42、軸受け43b及びこの軸受けに接続している上部保持部材49bなどを一体にキャプスタンローラ41から離れる方向に移動させる。また、この写真プリンタ10で搬送される最長の記録紙シート28を傾き補正した際に、傾き補正装置19の近傍に配置された搬送ローラ対40や、搬送ローラ対31が記録紙シート28を挟持してしまうときは、対応する搬送ローラ対に同様の解除機構を設けておく。本実施形態では、2列搬送を行うときは第3レジスト用ローラ対37の挟持状態を解除しておき、逆に第3レジスト用ローラ対37を用いて傾き補正を行うときは、第1及び第2レジスト用ローラ対35,36の挟持状態を解除しておく。   If the recording paper sheet 28 is pinched by another pair of conveyance rollers during the tilt correction operation, the registration operation cannot be performed. Therefore, a release mechanism (not shown) for releasing the clamping state of each registration roller pair 35, 36, 37 is provided. As an example of the release mechanism, a pinch roller 42, a bearing 43b, and an upper holding member 49b connected to the bearing are integrally moved away from the capstan roller 41 by using a shift mechanism including a cam, a spring, a solenoid, and the like. Move. Further, when the longest recording paper sheet 28 conveyed by the photographic printer 10 is corrected in inclination, the conveying roller pair 40 and the conveying roller pair 31 arranged in the vicinity of the inclination correcting device 19 sandwich the recording paper sheet 28. In such a case, a similar release mechanism is provided for the corresponding conveyance roller pair. In the present embodiment, when the two-row conveyance is performed, the nipping state of the third registration roller pair 37 is released, and conversely, when the inclination correction is performed using the third registration roller pair 37, The clamping state of the second registration roller pair 35, 36 is released.

次に、図4及び図5を用いて、2列搬送時に各記録紙シート28の先端辺を揃えるように傾き補正を行う方法について説明する。図4及び図5は、図2の傾き補正装置19を上面から見た平面図である。傾き補正を行う場合には、各レジスト用ローラ対35,36の両端部をそれぞれ反対方向に移動させたり、或いは移動量を変えて同一方向に移動させる方法がある。基本的には、後者の方法が用いられるが、各移動機構に使用されているボールねじ50a,50bの長さには限度がある。そのため、各記録紙シート28の傾き量の差が大きい場合には、各両端部を、その移動可能範囲の限度まで移動させたとしても、先端辺の位置を揃えることができない。従って、まず、各フォトセンサ38,39を通過する際に検出される各シート先端辺の4点(図中A、B、C、D)の通過時間差情報などから、4点間の最大の傾き量を求める。予め、この最大の傾き量と、各レジスト用ローラ対35,36の両端部の移動量との関係を求めておき、求められた移動量が移動可能範囲の限度に収まっているか否かで、各両端部をそれぞれ同一方向に移動させての傾き補正が可能か否かを判定できる。なお、詳しくは後述するが、各レジスト用ローラ対35,36の両端部を同一方向に移動させる際は、その移動量を最小にするため、レジスト用ローラ対35,36の4つの端部のうちの1つを固定し、他の3つの端部を搬送方向側に移動させて先端辺の位置を揃える。固定する端部は、A〜D点の中で最先端に位置する点側、つまり、本実施形態ではレジスト用ローラ対35の左端部である。   Next, with reference to FIGS. 4 and 5, a description will be given of a method of correcting the inclination so that the leading edges of the recording paper sheets 28 are aligned during the two-row conveyance. 4 and 5 are plan views of the tilt correction device 19 of FIG. 2 as viewed from above. In the case of performing the inclination correction, there are methods of moving both ends of each of the registration roller pairs 35 and 36 in opposite directions, or changing the movement amounts in the same direction. Basically, the latter method is used, but the lengths of the ball screws 50a and 50b used in each moving mechanism are limited. For this reason, when the difference between the tilt amounts of the recording paper sheets 28 is large, the positions of the front end sides cannot be aligned even if both end portions are moved to the limit of the movable range. Accordingly, first, the maximum inclination between the four points is determined from the passing time difference information of the four points (A, B, C, and D in the figure) detected at the time of passing through the photosensors 38 and 39. Find the amount. The relationship between the maximum inclination amount and the movement amounts of both ends of each registration roller pair 35 and 36 is obtained in advance, and whether or not the obtained movement amount is within the limit of the movable range, It can be determined whether or not inclination correction is possible by moving each end in the same direction. As will be described in detail later, when both ends of each registration roller pair 35, 36 are moved in the same direction, the four end portions of the registration roller pair 35, 36 are minimized in order to minimize the amount of movement. One of them is fixed, and the other three ends are moved to the transport direction side to align the positions of the front end sides. The end to be fixed is a point located at the forefront among the points A to D, that is, the left end of the registration roller pair 35 in this embodiment.

同一方向に移動させての傾き補正が可能と判定されたときは、図4(a)に示すように、A〜D点の中で最先端に位置するB点を基準とし、他の3点の位置をB点に合わせるようにする。つまり、第1レジスト用ローラ対35の第2移動機構43bは固定した状態で、第1移動機構43aのみを駆動して傾き補正を行った後の記録紙シート28の先端辺の位置を揃え位置とする。第2レジスト用ローラ対36では、CD間の傾きを修正しつつ、傾き補正後の先端辺を揃え位置に合わせるように、各移動機構55a,55bの駆動を制御する。これにより、(b)に示すように、各両端部または少なくともその片方を同一方向に移動させつつ、各記録紙シート28の先端辺を揃えるように傾き補正を行うことができる。   When it is determined that the tilt correction by moving in the same direction is possible, as shown in FIG. 4A, the other three points are based on the point B positioned at the forefront among the points A to D. The position of is aligned with point B. That is, with the second moving mechanism 43b of the first registration roller pair 35 fixed, the position of the leading end side of the recording paper sheet 28 after the tilt correction is performed by driving only the first moving mechanism 43a is aligned. And The second registration roller pair 36 controls the driving of the moving mechanisms 55a and 55b so that the tip side after the tilt correction is aligned with the alignment position while correcting the tilt between the CDs. As a result, as shown in (b), it is possible to perform inclination correction so that the leading edges of the recording paper sheets 28 are aligned while moving both ends or at least one of them in the same direction.

また、4点間の最大傾き量から、各両端部をそれぞれ同一方向に移動させての傾き補正が不可能と判定されたときは、図5(a)に示すように、A〜D点の中で最先端に位置するA点を通る最先端位置(図中、2点鎖線)と、最後端に位置するC点を通る最後端位置(図中、1点鎖線)との中間位置(図中、点線)を揃え位置とする。そして、各レジスト用ローラ対35,36は、それぞれAB間、CD間の傾きを修正しつつ、傾き補正後の先端辺を揃え位置に合わせるように、各移動機構43a,43b,55a,55bの駆動を制御する。これにより、(b)に示すように、各記録紙シート28の傾き量の差が大きい場合でも、その先端辺が揃うように傾き補正を行うことができる。   Further, when it is determined from the maximum amount of inclination between the four points that inclination correction is not possible by moving both ends in the same direction, as shown in FIG. An intermediate position (shown by a one-dot chain line in the figure) between a leading edge position (two-dot chain line in the figure) passing through the point A located in the leading edge and a last end position (one-dot chain line in the figure) passing through the point C located at the last end. (Middle, dotted line) is the alignment position. Each of the registration roller pairs 35 and 36 corrects the inclination between AB and CD, and adjusts the tip side after the inclination correction to the alignment position so that each of the moving mechanisms 43a, 43b, 55a and 55b Control the drive. As a result, as shown in (b), even when the difference in the amount of inclination of each recording paper sheet 28 is large, the inclination correction can be performed so that the leading edges thereof are aligned.

傾き補正後の各記録紙シート28は、主走査方向(図2及び図3参照)に位置がずれている場合がある。主走査方向にずれが発生していると、露光装置21おいて露光される画像が主走査方向にずれてしまう。そのため、例えば、傾き補正後の主走査方向におけるずれ量を測定するずれ量測定センサを設けるか、或いは、傾き補正を行う際に検出された傾き量などを用いてずれ量を算出するなどして、主走査方向のずれ量を求める。そして、求められたずれ量の値に基づいて、露光装置21の主走査方向の記録位置をずらせばよい。   Each recording paper sheet 28 after tilt correction may be displaced in the main scanning direction (see FIGS. 2 and 3). When a deviation occurs in the main scanning direction, an image exposed in the exposure device 21 is displaced in the main scanning direction. For this reason, for example, a displacement amount measuring sensor for measuring the displacement amount in the main scanning direction after the inclination correction is provided, or the deviation amount is calculated using the inclination amount detected when the inclination correction is performed. The amount of deviation in the main scanning direction is obtained. Then, the recording position of the exposure apparatus 21 in the main scanning direction may be shifted based on the obtained deviation amount value.

傾き補正装置19には、端数処理時や、2列搬送できないサイズの大きい記録紙シート28を単列搬送したときに傾き補正を行う第3レジスト用ローラ対37が設けられているが、これを設ける代わりに、図6に示すように第1、第2レジスト用ローラ対35,36を保持する保持台60と、この保持台60を主走査方向に対して平行な方向に移動させる保持台移動機構61とを設ける。これにより、第1、第2レジスト用ローラ対35,36を一体に主走査方向に対して平行な方向に移動させることができる。つまり、傾き補正と同時に記録紙シート28の主走査方向位置を任意に調整することができる。これにより、端数処理時に各レジスト用ローラ対35,36のいずれか一方、例えば、第2レジスト用ローラ36にのみ記録紙シート28が搬送されているときは、第2レジスト用ローラ36において傾き補正を行うのと同時に、保持台移動機構61を駆動して、記録紙シート28を搬送経路の中央に移動させることができる。   The tilt correction device 19 is provided with a third registration roller pair 37 that performs tilt correction when fraction processing is performed or when a large recording paper sheet 28 that cannot be transported in two rows is transported in a single row. Instead of providing, as shown in FIG. 6, a holding table 60 that holds the first and second registration roller pairs 35 and 36, and a holding table movement that moves the holding table 60 in a direction parallel to the main scanning direction. A mechanism 61 is provided. As a result, the first and second registration roller pairs 35 and 36 can be moved together in a direction parallel to the main scanning direction. That is, the position in the main scanning direction of the recording paper sheet 28 can be arbitrarily adjusted simultaneously with the tilt correction. Thus, when the recording paper sheet 28 is conveyed only to one of the registration roller pairs 35, 36, for example, the second registration roller 36 at the time of fraction processing, the second registration roller 36 corrects the inclination. At the same time, the holding table moving mechanism 61 can be driven to move the recording paper sheet 28 to the center of the transport path.

端数処理する記録紙シート28の枚数が多い場合には、図7に示すように、傾き補正を行うのと同時に、各列に交互に振り分けて2列搬送させるようにしてもよい。この場合には、露光装置21において同時露光ができるように、振り分け時、または露光装置21に搬送されるまでの間に、振り分けられた各記録紙シート28の先端辺の位置を揃えておく。   When the number of the recording paper sheets 28 to be rounded is large, as shown in FIG. 7, at the same time as performing the inclination correction, it may be alternately distributed to each row and conveyed in two rows. In this case, the positions of the front end sides of the distributed recording paper sheets 28 are aligned so that the exposure apparatus 21 can perform simultaneous exposure, at the time of distribution or before being conveyed to the exposure apparatus 21.

第1、第2レジスト用ローラ対35,36にまたがるようなサイズの大きい記録紙シート28を搬送するときは、保持台移動機構61を駆動して、第1、第2レジスト用ローラ対35,36のいずれか一方を搬送経路の中央に移動させるのと同時に、他方のレジスト用ローラ対の挟持状態を解除しておくことで、傾き補正を行うことができる。また、この場合には、傾き補正を行う代わりに、搬送停止状態、且つ挟持状態の搬送ローラ対40のローラ間に、この記録紙シート28の先端辺を当接させて傾きを補正する、いわゆるトップレジストを行ってもよい。さらに、各レジスト用ローラ対35,36を回転駆動する搬送モータのパルスレートを変え、各レジスト用ローラ対35,36のシート搬送速度を変えることで傾き補正を行ってもよい。   When transporting a large recording paper sheet 28 that straddles the first and second registration roller pairs 35 and 36, the holding table moving mechanism 61 is driven so that the first and second registration roller pairs 35, The tilt correction can be performed by moving any one of 36 to the center of the transport path and releasing the holding state of the other registration roller pair at the same time. In this case, instead of performing the inclination correction, the leading edge of the recording paper sheet 28 is brought into contact with the rollers of the conveyance roller pair 40 in the conveyance stopped state and the nipping state to correct the inclination. A top resist may be applied. Further, the tilt correction may be performed by changing the pulse rate of the conveyance motor that rotationally drives each registration roller pair 35 and 36 and changing the sheet conveyance speed of each registration roller pair 35 and 36.

次に、本構成の写真プリンタ10の動作について説明する。ユーザよりプリント指示がなされると、図1に示したように、各マガジン12,13の記録紙ロール25から感光記録紙24が送り出されて、カッタ15,16によって所定長の記録紙シート28にカットされる。カットされた各記録紙シート28は、搬送ローラ対30によって裏印字装置18に並列に送り込まれて、そこで、フイルムIDやコマ番号などの必要情報が印字される。   Next, the operation of the photo printer 10 having this configuration will be described. When the user gives a print instruction, as shown in FIG. 1, the photosensitive recording paper 24 is sent out from the recording paper roll 25 of each magazine 12, 13, and the recording paper sheet 28 of a predetermined length is formed by the cutters 15, 16. Cut. Each of the cut recording paper sheets 28 is sent in parallel to the back printing device 18 by the conveying roller pair 30, where necessary information such as a film ID and a frame number is printed.

裏印字された各記録紙シート28は、搬送ローラ対31によって傾き補正装置19に送られる。傾き補正装置19では、図2〜図5に示したように、フォトセンサ38,39を各記録紙シート28が通過する際に検出される計4点の通過時間差情報などから、各記録紙シート28の傾き量や傾いている方向を検出する。また、同時に各レジスト用ローラ対35,36の両端部を同一方向に移動させての傾き補正及び先端辺の揃えが可能であるか否かを判定する。   Each recording paper sheet 28 printed on the back side is sent to the tilt correction device 19 by the conveying roller pair 31. As shown in FIGS. 2 to 5, the inclination correction device 19 uses each of the recording paper sheets based on a total of four passing time difference information detected when the recording paper sheets 28 pass through the photosensors 38 and 39. The amount of inclination 28 and the direction in which it is inclined are detected. At the same time, it is determined whether or not the inclination correction and the alignment of the leading edge can be performed by moving both ends of each of the registration roller pairs 35 and 36 in the same direction.

可能と判定された場合には、上述したように、これら4点の中で最先端に位置する点を基準とするとともに、対応する移動機構43a,43b,55a,55bを制御して、他の3点の位置をそれに合わせるように同一方向に移動させることで、傾き補正及び先端辺の揃えを行う。また、不可能と判定された場合には、これら4点の中で最先端に位置する点を通る最先端位置と、最後端に位置する点を通る最後端位置との中間位置を揃え位置とする。そして、各記録紙シート28の傾きを修正しつつ、傾き補正後の先端辺を揃え位置に合わせるように、各移動機構43a,44b,55a,55bを制御する。記録紙シート28を並列搬送させつつ、各記録紙シート28の先端辺を揃えるように傾き補正を行うことができる。   If it is determined that it is possible, as described above, the point located at the forefront of these four points is used as a reference, and the corresponding moving mechanisms 43a, 43b, 55a, 55b are controlled to Inclination correction and tip edge alignment are performed by moving the three points in the same direction so as to match them. In addition, when it is determined that it is impossible, an intermediate position between the leading edge position passing through the point located at the leading edge among these four points and the trailing edge position passing through the point located at the trailing edge is set as the alignment position. To do. Then, the movement mechanisms 43a, 44b, 55a, and 55b are controlled so that the front end side after the inclination correction is adjusted to the alignment position while correcting the inclination of each recording paper sheet 28. Tilt correction can be performed so that the leading edges of the recording paper sheets 28 are aligned while the recording paper sheets 28 are conveyed in parallel.

傾き補正された各記録紙シート28は、搬送ローラ対40及び搬送ローラ対31によって露光装置21に搬送され、そこで、2列同時に画像が露光される。そして、露光済みの記録紙シート28は現像装置22に搬送されて、発色現像、定着、洗浄、乾燥の各処理が施された後、写真プリントとして写真プリンタ10の外部へ送り出される。   Each of the recording paper sheets 28 whose inclination has been corrected is transported to the exposure device 21 by the transport roller pair 40 and the transport roller pair 31, where two rows of images are exposed simultaneously. Then, the exposed recording paper sheet 28 is conveyed to the developing device 22 and subjected to color development, fixing, washing, and drying, and then sent out to the outside of the photographic printer 10 as a photographic print.

なお、本実施形態では、傾き補正及び先端辺の揃えを同時に行うようにしているが、例えば、第1,第2レジスト用ローラ対35,36では、傾き補正のみを行い、傾き補正後の各記録紙シート28を搬送ローラ対40のローラ間に当接させる(トップレジストする)ことで、傾きの再調整及び先端辺の揃えを行うようにしてもよい。また、逆に、傾き補正後の先端辺のずれ量が約2mm以内に収まるときは、先端辺の揃えは行わずに、露光装置21において各記録紙シート28に露光を開始する位置を副走査方向にずらすようにしてもよい。なお、傾き補正後の先端辺のずれ量は、例えば、先端辺のずれ量を測定するずれ量測定センサを設けるか、或いは、傾き補正を行う際に検出された傾き量などを用いて算出することで求められる。   In the present embodiment, the tilt correction and the alignment of the leading edge are performed at the same time. However, for example, the first and second registration roller pairs 35 and 36 perform only the tilt correction, and each after the tilt correction is performed. The recording paper sheet 28 may be brought into contact with the rollers of the conveying roller pair 40 (top registration) so as to readjust the inclination and align the leading edge. Conversely, when the amount of deviation of the leading edge after inclination correction is within about 2 mm, the alignment of the leading edge is not performed, and the position at which exposure is started on each recording paper sheet 28 in the exposure device 21 is sub-scanned. You may make it shift to a direction. Note that the amount of deviation of the tip side after the inclination correction is calculated using, for example, a deviation amount measurement sensor that measures the amount of deviation of the tip side, or the amount of inclination detected when the inclination correction is performed. Is required.

また、本実施形態では、各レジスト用ローラ対35,36,37のシート搬送方向上流側に配置されたフォトセンサ38,39によって記録紙シート28の傾きを検出するようにしたが、本発明はこれに限定されるものではない。記録紙シート28は、カッタ15,16によってカットされた時点で既に傾いている場合が多い。これは、各マガジン12,13の給紙口から感光記録紙24が送り出された時点で傾きが発生しているということであり、記録紙シート28の傾き量及びその方向は、個々のマガジンによって決まってしまう場合が多い。従って、予め、各マガジン毎の記録紙シートの傾き量を測定して、この測定結果をデータテーブル化し、写真プリンタ10のコントローラ57などに記憶させておく。そして、ユーザが使用するマガジンの種類を選択するか、或いはセットされたマガジンの種類を写真プリンタ10が自動認識するようにしておくことで、セットされたマガジンの種類に応じた傾き補正を行うようにしてもよい。   In this embodiment, the inclination of the recording paper sheet 28 is detected by the photosensors 38 and 39 arranged on the upstream side in the sheet conveyance direction of each of the registration roller pairs 35, 36, and 37. It is not limited to this. In many cases, the recording paper sheet 28 is already inclined when it is cut by the cutters 15 and 16. This means that there is an inclination when the photosensitive recording paper 24 is sent out from the paper feed opening of each magazine 12, 13, and the inclination amount and the direction of the recording paper sheet 28 depend on the individual magazine. Often decided. Therefore, the inclination amount of the recording paper sheet for each magazine is measured in advance, and the measurement result is converted into a data table and stored in the controller 57 of the photo printer 10 or the like. Then, the user selects the type of magazine to be used, or the photo printer 10 automatically recognizes the type of magazine that has been set, so that tilt correction according to the type of magazine that has been set is performed. It may be.

なお、本実施形態の写真プリンタ10では、記録紙シート28を2列搬送して、2列同時傾き補正及び2列同時露光を行っているが、記録紙シート28を並列搬送させる列数は2列に限定されるものではなく、3列以上でもよい。この場合には、列数分だけ上述のレジスト用ローラ対を並列に配置しておけばよい。   In the photographic printer 10 of the present embodiment, the recording paper sheets 28 are conveyed in two rows to perform two-row simultaneous tilt correction and two-row simultaneous exposure. However, the number of rows in which the recording paper sheets 28 are conveyed in parallel is two. The number of rows is not limited, and three or more rows may be used. In this case, the above registration roller pairs may be arranged in parallel by the number of rows.

また、本実施形態の傾き補正装置19は直線状の搬送経路に配置されているが、湾曲した搬送経路、例えば、搬送経路のコーナーに配置してもよい。この場合には、各レジスト用搬送ローラ対35,36,37の端部を搬送方向に対して垂直な方向(記録紙シート28の記録面に対して垂直な方向)に移動させ、故意に記録紙シート28をスキューさせることで、記録紙シート28の傾きを補正するようにしてもよい。なお、各レジスト用搬送ローラ対35,36,37の端部を垂直方向に移動させる場合には、傾き補正後の各記録紙シート28の先端辺の位置を揃えることはできないので、上述したように、傾き補正後の各記録紙シート28の先端辺のずれ量を求めて、この求められた結果に基づいて、露光装置21において各記録紙シート28に露光を開始する位置を副走査方向にずらせばよい。   Moreover, although the inclination correction apparatus 19 of this embodiment is arrange | positioned at the linear conveyance path | route, you may arrange | position in the curved conveyance path | route, for example, the corner of a conveyance path | route. In this case, the ends of the respective registration conveyance roller pairs 35, 36, and 37 are moved in a direction perpendicular to the conveyance direction (direction perpendicular to the recording surface of the recording paper sheet 28) to intentionally record. The skew of the recording paper sheet 28 may be corrected by skewing the paper sheet 28. Note that when the ends of the registration roller pairs 35, 36, and 37 are moved in the vertical direction, the positions of the leading edges of the recording paper sheets 28 after the inclination correction cannot be made uniform, as described above. Further, the deviation amount of the leading edge of each recording paper sheet 28 after the inclination correction is obtained, and based on the obtained result, the position at which exposure of each recording paper sheet 28 is started in the exposure apparatus 21 in the sub-scanning direction. Just shift it.
