发明名称 Transfer device
摘要 The present invention is to eliminate loosening of a transfer film on a rear end side of a card caused due to collision of a front end of the card against a conveying roller pair provided downstream of a transfer roller to prevent wrinkles from occurring in a transferred image. A rotation amount of a card conveying motor SMr and a wind amount of a transfer film 46 (conveying amount of the transfer film) are compared after a front end of a card K rushes into a conveying roller pair 37 during transfer processing for the card K to thereby detect a slip amount of the card K. A card conveying speed and a transfer film feed speed are controlled in accordance with the detected slip amount so as to eliminate loosening of the transfer film 46.

主权项 1. A transfer device that transfers, on a recording medium, an image on a transfer film which is formed by pressure contact between a heating member and a transfer platen through the transfer film, comprising: an image transfer section having the heating member and the transfer platen, in which the heating member and the transfer platen are configured to be movable between an actuation position at which they are brought into pressure-contact with each other and a retracted position at which they are separated from each other; a plurality of recording medium conveyors that convey the recording medium; a first detector that detects a drive amount of one of the recording medium conveyors during the transfer processing; a transfer film feeder that feeds, during the image transfer, the transfer film on an upstream side relative to the heating member in a transfer film conveying direction; a transfer film conveyor that feeds, during the image transfer, the transfer film on a downstream side relative to the heating member in a transfer film conveying direction; a second detector that detects a transfer film conveying amount by the transfer film conveyor during the transfer processing; and a controller that controls the image transfer section, the recording medium conveyors, the transfer film feeder, and the transfer film conveyor, wherein at least one of the recording medium conveyors is provided downstream of the heating member in the transfer direction, and after a front end of the recording medium reaches the recording medium conveyor provided downstream of the heating member, the controller increases the conveying amount of the recording medium and/or reduces the transfer film feed amount in accordance with detection results of the first and second detectors.
