SHEET PROCESSING MACHINE

To provide a sheet processing machine which can specify a tip that is a reference position for processing and perform processing at an accurate position regardless of the tip shape of a sheet.SOLUTION: The sheet processing machine includes a conveyance section 12 that conveys sheets 100 in a conveying direction F, a processing section 21 that performs processing on processing surfaces of the sheets 100, a tip detection section 45 for detecting tips 107 of the sheets conveyed in the conveying direction, a moving section 15 that integrally moves the processing section and the tip detection section in a width direction W that intersects the conveying direction and a control section 10 for controlling each operation of the conveying section, the processing section, and the moving section. The control section controls the conveying section, the processing section, and the moving section so that the processing section processes the processing surfaces of the sheets based on the tips of the sheets detected by the tip detection section.SELECTED DRAWING: Figure 11 【課題】シートの先端形状にかかわらず、加工の基準位置となる先端を特定でき、正確な位置に加工を施すことができるシート加工機を提供する。【解決手段】シート１００を搬送方向Ｆに搬送する搬送部１２と、シート１００の加工面に対して加工を行う加工部２１と、搬送方向に搬送されるシートの先端１０７を検出する先端検出部４５と、搬送方向に交差する幅方向Ｗに対して、加工部および先端検出部を一体的に移動させる移動部１５と、搬送部と加工部と移動部との各動作を制御する制御部１０とを備え、制御部は、先端検出部によって検出されたシートの先端を基準にして、加工部がシートの前記加工面に対して加工を行うように、搬送部と加工部と移動部とを制御する。【選択図】図１１
