Abstract
Description
図1は、第1の実施形態に係る製本システム10の全体構成図である。製本システム10は、給紙装置12、中綴じ折り装置14、断裁装置16、スタッカ18、および管理装置20を有する。
糊転写機構30は、糊シートユニット120、送り駆動機構122、転写作動機構124、およびストッパ駆動機構126を有する。
図6は、糊シート212の詳細を示す部分拡大図である。(A)はその一実施例を示し、(B)は他の実施例を示し、(C)は第1の実施形態では採用しない比較例を示している。同図における上下方向が糊シート212の長手方向(送り方向)となっている。
第1の実施形態では、糊シート212を無駄なく効率的に消費できるよう、転写方法を工夫している。すなわち、転写工程へ移行する際に、糊シート212の糊転写済み部分310と糊未転写部分312との境界(「転写境界」という)314が、押圧面284と受圧面240との押圧範囲Aに含まれるように停止され、その状態で次の転写処理が行われる。第1の実施形態では、押圧面284よりも受圧面240を小さく構成しているため、押圧範囲Aは、実質的に受圧面240の幅と等しくなっている。つまり、押圧範囲Aは、受圧面240の上流側の端部稜線241と下流側の端部稜線243とを挟む領域ということになる。ただし、糊の転写長さlを確保するため、転写境界314を受圧面240の下流側端部の近傍(端部稜線243の近傍)に設定している。このように、転写境界314を押圧範囲A内に設定することで、糊シート212が無駄なく使用されるようになる。
図10は、第2の実施形態に係る製本システム400の一つの構成例を示す図である。以下、第1の実施形態に係る製本システム10と同様の個所は同一の符号を付して説明を省略する。
図13は、第3の実施形態に係る製本システム600の全体構成図である。以下、上述の実施形態に係る製本システムと同様の個所は同一の符号を付して説明を省略する。
図20は、第4の実施形態に係る製本システム700の全体構成図である。以下、上述の実施形態に係る製本システムと同様の個所は同一の符号を付して説明を省略する。
図24は、第5の実施形態に係る製本システム800の全体構成図である。製本システム800は、丁合装置410に代えて給紙装置802が設けられた以外は、第3の実施形態に係る製本システム600と同様に構成される。
