Abstract

A drive transmission device () includes a first drive train () and a second drive train (). The first drive train () includes a first gear (), a second gear (), a rotary shaft (), and one-way clutches (). The second drive train () includes a third gear (), a fourth gear (), a rotary shaft (), and an electromagnetic clutch (). The third gear () engages the first gear () and the fourth gear () engages the second gear (). A rotational speed of a pickup roller () is switched by switching on/off the electromagnetic clutch () to change a transmission path of driving force.
