Abstract
Herein disclosed is a recording apparatus for printing on opposite surfaces of recording medium which comprises: printing means for printing one surface of recording medium in a printing position; a looped conveyor passage for conveying again the recording medium having the printed one surface to the printing position so that another surface may be printed; and turning means disposed in the conveyor passage for turning the opposite surfaces of the once-printed recording medium upside down in a direction perpendicular to the conveying direction thereof with the tops and bottoms being in an identical arrangement.

A recording apparatus for printing on opposite surfaces of a recording medium comprising:
- printing means for printing on one surface of a recording medium when the recording medium is conveyed to a printing position;
- means including a looped conveyor passage for conveying in a conveying direction the recording medium having a printed one surface to said printing position so that the opposite surface of the recording medium may be printed;
- turning means disposed in said conveyor passage for turning the opposite surface of the once-printed recording medium upside down in a transverse direction perpendicular to the conveying direction thereof with the tops and bottoms of both surfaces of the recording medium being in an identical arrangement;
- and
- switching means disposed in the vicinity of said turning means for switching the feed of said recording medium from the transverse direction to the original conveying direction, the switching means comprising a feed roller for feeding the recording medium in the conveying direction, a holding roller mounted to make elastic contact with said feed roller, a pivotable lever having said holding roller rotatably mounted thereon and pivotable in one direction to move said holding roller out of contact with said feed roller and pivotable in an opposite direction to move said holding roller into elastic contact with said feed roller, and an eccentric cam for pivotally actuating said lever.
A recording apparatus for printing on opposite surfaces of a recording medium comprising:
- conveying means having an upstream conveying section for conveying a recording medium in an advancing direction to a printing station to enable printing on one surface of the recording medium and having a downstream conveying section for conveying the once-printed recording medium in the advancing direction to a turning station to enable turning upside-down of the once-printed recording medium;
- printing means operable when the recording medium is at the printing station for printing on one surface of the recording medium;
- turning means operable when the once-printed recording medium is at the turning station for turning the recording medium in a direction transverse to the advancing direction to turn the recording medium upside down without inverting the leading and trailing ends thereof, the turning means including first feeding means actuatable to a first position to enable the recording medium to be delivered to and discharged from the turning station and actuatable to a second position for feeding the recording medium through the turning station, and first camming means for actuating the first feeding means to the first and second positions;
- and transporting means for transporting the upside-down recording medium from the turning station to the upstream conveying section for conveyance to the printing station to enable printing on the other surface of the recording medium, the transporting means including second feeding means actuatable to a first position to enable the upside-down recording medium discharged from the turning station to be delivered to the transporting means and actuatable to a second position for feeding the upside-down recording medium to the upstream conveying section, and second camming means for actuating the second feeding means to the first and second positions in synchronism with the first camming means such that the first feeding means is in its first position when the second feeding means is in its second position and the first feeding means is in its second position when the second feeding means is in its first position.
