Abstract: An image formation apparatus includes: a conveyance unit provided to convey a long medium provided with conveyance indexes at a predetermined conveyance index spacing; a print unit provided to perform printing on the medium; a cutter unit provided to cut the medium; an index detector provided to detect the conveyance indexes; a print controller configured to drive the print unit to perform printing in response to detection of the conveyance indexes; a cut controller configured to cause the cutter unit to cut the medium in response to detection of the conveyance indexes; and a conveyance controller configured to form a slack in the medium by driving the conveyance unit. The print controller performs printing based on a virtual conveyance index when the medium having the slack is cut.

Abstract: An invented medium delivery apparatus includes a delivery unit, a medium stacking unit, a detection unit, and a sensor. The delivery unit delivers a conveyed medium. The medium stacking unit stacks the medium delivered from the delivery unit. The detection unit is disposed between the delivery unit and the medium stacking unit in a medium conveyance direction, and detects an amount of the medium delivered to the medium stacking unit. The sensor senses a motion of the detection unit. The detection unit has a detachable tip portion. The medium delivery apparatus is able to change the sheet number of media stacked on the medium stacking unit where the medium stacking unit is in a full status with the stacked media.
