1. A foil transfer apparatus configured to superpose a sheet on a foil film including a foil and to transfer the foil to the sheet, the foil transfer apparatus comprising:
a housing body having an opening;
a cover movable between a closed position at which the cover closes the opening and an open position at which the cover exposes the opening;
a lock mechanism capable of locking the cover at the closed position;
a heating member configured to heat the foil film and the sheet;
a pressurizing member configured to cooperate with the heating member to nip the foil film and the sheet therebetween;
a temperature sensor; and
a controller,
wherein the controller is configured to
determine a first correction value based on one, or two or more of (i) a width of the foil film, (ii) a position on which the foil film is mounted, (iii) a width of the sheet, (iv) a thickness of the sheet, and (v) a foil transfer mode,
calculate a first lock determination temperature and a second lock determination temperature, the first lock determination temperature being a value obtained by adding the first correction value to a detection temperature detected by the temperature sensor, the second lock determination temperature being a value obtained by adding a second correction value that is different from the first correction value to the detection temperature detected by the temperature sensor,
control the lock mechanism to lock the cover when the first lock determination temperature is not lower than a first threshold, and
control the lock mechanism to unlock the cover when the second lock determination temperature is lower than a second threshold.
