Image forming device

摘要

An image forming device, comprising: a sheet-like medium accommodation unit; a supply member that carries a sheet-like medium; a pair of separation members that separate the sheet-like medium one by one; an image formation unit; a carrying path; a re-carrying unit to move inversely the sheet-like medium whose top face has been subjected to printing; a moving mechanism to move the supply member close to or away from the sheet-like medium and to move the pair of separation members close to or away from each other so that a path for the inversely carried sheet-like medium is formed; and a control unit to control the moving mechanism such that, when back-face printing is performed, the supply member is in a state of being moved away from the sheet-like medium and the pair of separation members are in a state of being moved away from each other.

1. An image forming device, comprising:
a sheet-like medium accommodation unit provided in a lower part of a main body; a supply member that carries a sheet-like medium accommodated in the sheet-like medium accommodation unit; a pair of separation members that separate the sheet-like medium carried by the supply member one by one and carry the sheet-like medium, the pair of separation members including a first separation member and a second separation member; an image formation unit that is arranged above the sheet-like medium accommodation unit and is configured to form an image on the sheet-like medium carried from the pair of separation members; a carrying path that is formed in a shape of a letter U to connect the sheet-like medium accommodation unit with the image formation unit, the supply member and the pair of separation members being arranged along the carrying path; a re-carrying unit configured to move inversely the sheet-like medium whose top face has been subjected to printing by the image formation unit and to carry again the inversely moved sheet-like medium to the image formation unit through a portion between the supply member and the sheet-like medium accommodated in the sheet-like medium accommodation unit and a portion between the pair of separation members; a moving mechanism configured to move the supply member close to or away from the sheet-like medium accommodated in the sheet-like medium accommodation unit and to move the pair of separation members close to or away from each other so that a path for the inversely carried sheet-like medium is formed between the supply member and the sheet-like medium accommodated in the sheet-like medium accommodation unit and between the pair of separation members; and a control unit configured to control the moving mechanism such that,
when the sheet-like medium fed from the sheet-like medium accommodation unit passes between the pair of separation members, the first separation member is urged against the second separation member so as to pinch the sheet-like medium between the pair of separation members, andwhen the sheet-like medium is fed by the re-carrying unit, the supply member is in a state of being moved away from the sheet-like medium accommodated in the sheet-like medium accommodation unit and the pair of separation members are in a state of being moved away from each other so that the sheet-like medium passes between the pair of separation members.
