摘要： An image forming apparatus includes a process unit, a heating unit, and a controller unit. The process unit is configured to transfer an image onto a sheet. The heating unit is configured to fix the image transferred at the process unit onto the sheet, and to transfer a transfer layer onto an image formed on a sheet overlaid on a multilayer film. The controller unit is capable of operating in a first printing mode in which processes of transferring an image at the process unit, fixing the image at the heating unit, and transferring the transfer layer at the heating unit are executed, and a second printing mode in which processes of transferring an image at the process unit and fixing the image at the heating unit are not executed, and a process of transferring the transfer layer at the heating unit is executed.

摘要： A sheet tray includes a first tray, a second tray, and a third tray. The second tray is configured to move between a stored position and an extended position, relative to the first tray. The third tray is pivotable about the pivot shaft between a first stowed position and a first extended position, relative to the second tray. One of the first tray and the third tray includes a columnar portion. The columnar portion protrudes toward the other of the first tray and the third tray in an area where, when the second tray is at the stored position and the third tray is at the first stowed position, the first tray overlaps the third tray in an orthogonal direction. The other includes a cutout shaped along a path where the columnar portion moves when the third tray moves from the first stowed position to the first extended position.

摘要： In a foil transfer device for transferring a transfer layer from a foil film onto a sheet laid on the foil film, the foil film is wound on a supply reel, and taken up on a take-up reel. A heating member heats the foil film, and a pressure member is provided to press the foil film and the sheet between the pressure member and the heating member. A separator changes a traveling direction of the foil film having passed through between the heating member and the pressure member into a direction different from a direction of conveyance of the sheet, to thereby separate the foil film from the sheet. A first fan blows air toward the foil film positioned between the heating member and the separator.

摘要： A memory holder cover holds a memory holder so as to be movable with respect to the memory holder cover. An electrical contact contacts an electrical contact surface of a memory from above in a state where a cartridge is located at an attached position at which the cartridge is attached to a main housing. The main housing includes a guide groove having upper and lower guide surfaces. The upper guide surface guides movement of a memory holder from above when the cartridge is attached and detached. The lower guide surface guides movement of the memory holder from below when the cartridge is attached and detached. In a state where the cartridge is located at the attached position, the electrical contact surface is parallel to at least part of the upper guide surface or at least part of the lower guide surface.

摘要： 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.
