1. A media processing device comprising:
a conveyance path that guides a sheet medium; a drive source that conveys the medium along the conveyance path; a conveyance mechanism that conveys the medium by the drive source in one direction and the opposite direction through the conveyance path; a reversing conveyance path that reverses the front and back of the medium supplied by the conveyance mechanism from the conveyance path, and returns the medium to the conveyance path; a reversing conveyance mechanism that receives and conveys the medium fed into the reversing conveyance path through the reversing conveyance path, and then feeds the medium into the conveyance path and passes the medium to the conveyance mechanism; a reversing drive source that is separate from the drive source and drives the reversing conveyance mechanism; and a backlash part; the reversing conveyance mechanism including a reversing conveyance roller, and a gear train that transfers drive power from the reversing drive source to the reversing conveyance roller; and the backlash part enabling relative rotation in a preset angular range between two gears to which the drive power of the reversing drive source is directly transferred in the gear train, or between the final gear of the gear train and the reversing conveyance roller. |
