Abstract: A cutting device includes: a first guide portion that supports a sheet as a target to be cut; and a pair of cutting blades that cuts the sheet by performing a shearing operation on the sheet when the pair of cutting blades is in a state of pinching a cutting-target part of the sheet supported by the first guide portion from both sides thereof. The pair of cutting blades is configured of a fixed blade and a movable blade. The first guide portion supports the sheet in a manner in which the sheet is moved along a main transport surface that is so set as to pass through between the fixed blade and the movable blade when the fixed blade and the movable blade are not being engaged, and also supports the sheets so that the sheet can move from the main transport surface.
