Claim 0:
1. A layer transfer device comprising:
a housing having an opening;
a cover movable between a closed position in which the cover closes the opening and an open position in which the cover opens the opening;
a locking member movable between a locking position in which the locking member locks the cover to the closed position and an unlocking position in which the locking member permits movement of the cover from the closed position to the open position;
a heat roller positioned inside the housing, the heat roller being configured to heat a multilayer film and a sheet in a state where the cover is at the closed position, the multilayer film and the sheet being conveyed in a first direction in an overlaid state with each other, the multilayer film including a support layer and a supported layer, the supported layer including a transfer layer to be transferred to the sheet;
a plurality of temperature sensors including:
a first sensor configured to measure temperature of a first member, the first member being heated by one of the multilayer film and the sheet that have been heated by the heat roller; and
a second sensor configured to measure temperature of a second member, the second member being heated by the heat roller; and

a controller configured to perform:
(a) determining a plurality of evaluated temperatures on the basis of a plurality of temperatures measured by the plurality of temperature sensors;
(b) placing the locking member in the locking position in a case where at least one of the plurality of evaluated temperatures determined in (a) is equal to or higher than a first threshold value; and
(c) placing the locking member in the unlocking position in a case where all of the plurality of evaluated temperatures determined in (a) are lower than the first threshold value.
