<P>PROBLEM TO BE SOLVED: To improve driving accuracy of a rotating member etc. disposed so as to make their driving switchable. <P>SOLUTION: A switching unit 60 includes forward-and-backward moving members 70y, 70m, 70c and 70k which are moved forward and backward with respect to photoreceptor-side coupling members 18, linked with a first movable plate 83 and a second movable plate 84. When the first movable plate 83 slides upward to rotate the forward-and-backward moving members 70y, 70m and 70c, the forward-and-backward moving members 70y, 70m and 70c slide in a direction away from the photoreceptor-side coupling members 18y, 18m and 18c. Accordingly, driving-side coupling members slide in a direction away from the photoreceptor-side coupling members 18y, 18m and 18c as well. Consequently, the connection between the photoreceptor-side coupling member 18k and the driving-side coupling member corresponding to it is maintained and the connection between the photoreceptor-side coupling members 18y, 18m and 18c and the driving-side coupling members corresponding to them is released. <P>COPYRIGHT: (C)2009,JPO&INPIT |
