  • Publication number: 20210354500
    Abstract: A layer transfer device includes: a cover; a heat roller; a controller; temperature sensors including first and second sensors; and a locking member movable between a locking position to lock the cover to a closed position and an unlocking position to permit movement of the cover from the closed position to an open position. The first sensor measures temperature of a first member heated by a multilayer film or a sheet having been heated by the heat roller. The second sensor measures temperature of a second member heated by the heat roller. The controller determines evaluated temperatures based on temperatures measured by the temperature sensors, places the locking member in the locking position when at least one of the evaluated temperatures is not lower than a first threshold value, and places the locking member in the unlocking position when the evaluated temperatures are all lower than the first threshold value.
