PROBLEM TO BE SOLVED: To provide a conveyance device for conveying a sheet-like conveyance object material which can enhance the reduction rate of shock jitter due to the contact/separation operation of two rotors without reducing the conveyance efficiency.SOLUTION: A conveyance device which conveys a sheet-like conveyance object material between a first rotor provided in a rotatable manner and a second rotor provided in a rotatable manner and arranged so as to face the first rotor includes a contact/separation mechanism which can move at least a surface of at least any of the first rotor and the second rotor between a contact position where the first rotor and the second rotor contact the conveyance object material and a separation position where the first rotor is separated from the second rotor in a facing region where the first rotor and the second rotor face each other. The contact/separation mechanism moves at least the surface of any of the first rotor and the second rotor to any position between the separation position and the contact position from the separation position at the first speed, and then moves the surface to the contact position from the any position at the second speed slower than the first speed when moving the surface in the direction from the separation position to the contact position.SELECTED DRAWING: Figure 6 【課題】搬送効率を低減せずに、２つの回転体の接離動作によるショックジターの低減率を高めることができる、シート状の被搬送材を搬送する搬送装置の提供。【解決手段】回転可能に設けられた第１回転体と、回転可能に設けられ且つ前記第１回転体に対向配置される第２回転体との間でシート状の被搬送材を搬送する搬送装置であって、前記第１回転体と前記第２回転体とが対向する対向領域において、当該第１回転体と当該第２回転体とが前記被搬送材に接触する接触位置と、当該第１回転体と当該第２回転体とが離間している離間位置との間で、当該第１回転体と当該第２回転体の少なくとも何れかの回転体の少なくとも表面を移動可能な接離機構と、を備え、前記接離機構は、前記少なくとも何れかの回転体の少なくとも表面を前記離間位置から前記接触位置の方向へ移動させる際に、前記離間位置から前記離間位置と前記接触位置との間の任意の位置まで第１の速度で移動させ後、前記第１の速度よりも低速の第２の速度で前記任意の位置から前記接触位置へ移動させる。【選択図】図６
