Then, in the belt cleaning device 100A according to the first embodiment, the swinging means 102 that swings the driven rotating member 101 crosses the rotational motion obtained by the driven rotating member 101 with the rotating direction D1 of the transport belt 201. It is composed of a motion conversion mechanism 150 that converts the linear motion of the above.

More specifically, the rotating shaft 303 of the driven rotating member 101 is rotatably supported by bearing portions 302a and 302b provided on the side plates 301a and 301b arranged on the left and right sides of the driven rotating member 101.

In the figure, a motion conversion mechanism 150 is provided on the right side of the driven rotating member 101.

As shown in FIGS. 2 and 3, the motion conversion mechanism 150 includes a disk member 350 and a sliding contact member 361.

More specifically, the sliding contact member 361 has a pair of standing portions 361a and 361b that stand up on the rotation shaft 303 side.

The end portion 350a of the disk member 350 is set so as to be located between the standing portions 361a and 361b.

According to the motion conversion mechanism 150 having such a configuration, when the rotary shaft 303 is rotated in the D10 direction by the driven rotary member 101, the rotary motion reciprocates in the D2 direction due to the action of the disk member 350 and the sliding contact member 361. Is converted into a linear motion.

As a result, the rotating shaft 303 reciprocates in the D2 direction, and the driven rotating member 101 as a cleaning means directly connected to the rotating shaft 303 swings in the D2 direction.

Therefore, the driven rotating member 101 as a cleaning means intersects the transport direction D1 due to the swing of the driven rotating member 101 in addition to the removing force due to the rotation of the driven rotating member 101 with respect to the deposits of the transport belt 201 that come into contact with each other.
