Description

このように、本実施例においては、挟持搬送ローラ対46による感光材料Pの挟持を開放し、感光材料Pの先端辺を搬出ローラ対48のローラ間に当接させ、さらに感光材料Pを送り込むことにより、トップレジストによるスキューの補正を行うことができる。この場合、コーナー搬送部18において、感光材料Pの湾曲が最も大きい状態で、すなわち、感光材料Pの進路変更特性が高い状態で感光材料Pの先端辺を搬出ローラ対48のローラ間に突き当てることになるので、スキューの補正を極めて容易にできる。 As described above, in the present embodiment, the holding of the photosensitive material P by the holding conveyance roller pair 46 is released, the leading edge of the photosensitive material P is brought into contact with the rollers of the carry-out roller pair 48, and the photosensitive material P is further fed. that way, it is possible to correct the skew by top cash register strike. In this case, in the corner conveyance unit 18, the leading edge of the photosensitive material P is abutted between the rollers of the carry-out roller pair 48 in a state where the curvature of the photosensitive material P is the largest, that is, in a state where the path change characteristic of the photosensitive material P is high. As a result, the skew can be corrected very easily.

なお、本実施例においては、感光材料Pの先端辺のスキュー角度に応じて、第3の実施例の如く、搬出ローラ対48回転軸の角度を面方向で回転させてスキューを補正してもよい。 In this embodiment, according to the skew angle of the leading edge of the photosensitive material P, the skew is corrected by rotating the rotation shaft angle of the carry-out roller pair 48 in the surface direction as in the third embodiment. Also good.

また、上述の第2乃至第5の実施例において、振り分けを行う場合、搬送方向に沿って一列に、例えばフォトインタラプタなどのセンサを2個設け、感光材料Pを振り分ける際に、感光材料Pの側辺傾きを検出し、その検出結果に基づいて振り分けおよびスキューの補正をするようにしてもよい。
さらに、上述の実施例において、コーナー搬送部18が振り分けしか行わない場合には、センサ42、43を設ける必要はない。
さらにまた、上述の実施例において、感光材料Pの先端辺の傾きを検出するセンサを設けた場合、スキューの補正をするものを選別することができるので、スキューを補正しない場合、スキューをとるローラ対の回転を停止する必要がないので、その分、搬送時間を短縮できる。
In the second to fifth embodiments described above, when sorting, two sensors such as photo interrupters are provided in a line along the transport direction, and when the photosensitive material P is sorted, The inclination of the side may be detected, and sorting and skew correction may be performed based on the detection result.
Furthermore, in the above-described embodiment, when the corner transport unit 18 performs only sorting, the sensors 42 and 43 need not be provided.
Furthermore, in the above-described embodiment, when the sensor for detecting the inclination of the leading edge of the photosensitive material P is provided, it is possible to select the one that corrects the skew. Since it is not necessary to stop the rotation of the pair, the conveyance time can be shortened accordingly.

【発明の効果】
以上詳細に説明したように本発明によれば、湾曲している状態の感光材料を挟持搬送する挟持搬送手段を設けることにより、例えば挟持搬送手段の下流側にレジストレーション用ローラ対を設け、挟持搬送手段の挟持を開放した状態でシート体をレジストレーション用ローラ対に突き当てることにより、シート体のスキュー補正ができる装置を構成することができる。
また、例えば挟持搬送手段の下流側に、シート体を挟持した状態でシート体の搬送方向と直交する主走査方向に移動可能な搬出手段を設け、挟持搬送手段の挟持を開放した状態で主走査方向に振り分けることにより、シート体を振り分けることができる装置を構成することができる。このようにして、本発明においては、スキューの補正および振り分けの少なくとも一方ができる装置を簡単な構成で提供することができる。
さらに、シート体の搬送路を湾曲させることにより、装置を小型化することができる。

【The invention's effect】
As described above in detail, according to the present invention, a pair of registration rollers is provided on the downstream side of the nipping / conveying means, for example, by providing nipping / conveying means for nipping and conveying the photosensitive material in a curved state. An apparatus capable of correcting the skew of the sheet body can be configured by abutting the sheet body against the pair of registration rollers in a state in which the nipping of the conveying unit is released.
Further, for example, on the downstream side of the nipping / conveying means, a carrying-out means that can move in the main scanning direction orthogonal to the conveying direction of the sheet body is provided while the sheet body is nipped, and the main scanning is performed with the nipping / conveying means being opened. By allocating in the direction, an apparatus that can distribute the sheet body can be configured. Thus, in the present invention can be subjected Hisage at least one of a device capable of correcting and distribution of skew with a simple configuration.
Furthermore, the apparatus can be miniaturized by curving the sheet conveyance path.
