<P>PROBLEM TO BE SOLVED: To provide a web guide device ensuring a smooth operation and durability to a force applied from a web even if the device is used in an environment where paper powder and dust are dispersed. <P>SOLUTION: The web guide device includes an oscillating frame 4 oscillating around an axis orthogonal to a reference surface 2s of a base 2 and a support portion 40 supporting movement of the oscillating frame 4 to the base 2. The support portion 40 includes a base member 41 which is provided on the base 2 and has a rolling surface parallel to the reference surface 2s of the base 2, and a roller 46 provided on the oscillating frame 4 so as to roll on the rolling surface of the base member 41. The rolling surface of the base member 41 is formed such that the axial direction thereof intersects with an arc centered on the oscillation axis 3 of the oscillating frame 4. The roller 46 is wider than the rolling surface of the base member 41 and is provided so as to move along the arc centered on the oscillation axis 3 of the oscillating frame 4 when the oscillating frame 4 oscillates. <P>COPYRIGHT: (C)2012,JPO&INPIT |
