Abstract
The present invention relates to a recording apparatus comprising a conveyance roller; a driven roller rotating as driven from the conveyance roller; pushing means for pushing the driven roller to the conveyance roller;a bearing for supporting the conveyance roller; driving means for rotating the conveyance roller; and drive transmitting means. The bearing includes two contact portions with the circumference of a spindle for supporting the conveyance roller and the bearing supports the conveyance roller as to locate a perpendicular direction of a line coupling the two contact portions within a varying range of a vector direction of exertion force exerted to the bearing at a time of stop and operation of the conveyance roller.
