PROBLEM TO BE SOLVED: To provide a new sheet material feed mechanism achieving downsizing and space saving.SOLUTION: A sheet material feed mechanism 100 comprises: rail members 10 a plurality of driven members 20 movable along the rail members 10 and surrounding the rail members 10 in a rotatable state a sheet material 30 entrained by the driven members 20 and drive means 40 for driving the driven members 20. The drive means 40 includes a rotor in which a plurality of rotating wheels are arranged. Each rotating wheel can take a drive position where the sheet material 30 is sandwiched between the driven member 20 and the rotating wheel. When the rotating wheel takes the drive position, a rotary shaft of each rotating wheel is arranged in non-parallel and non-perpendicular in a length direction of the driven member 20 along an extension direction of the rail member 10.SELECTED DRAWING: Figure 10COPYRIGHT: (C)2017,JPO&INPIT【課題】小型化又は省スペース化に資する新しいシート材送り機構を提供する。【解決手段】シート材送り機構100は、レール部材10と、レール部材10沿いに移動可能であり、回転可能な状態でレール部材10を周囲する複数の被駆動部材20と、被駆動部材20に連行されるシート材30と、被駆動部材20を駆動するための駆動手段40を備える。駆動手段40は、複数の回転輪が配列された回転体を含む。各回転輪は、被駆動部材20と回転輪の間でシート材30が挟まれる駆動位置を取ることができる。各回転輪の回転軸は、回転輪が駆動位置を取る時、レール部材10の延在方向に沿う被駆動部材20の長さ方向に関して非平行及び非垂直に配される。【選択図】図10
