Abstract: A cutting apparatus includes an angle change unit configured to change an angle made by a cutting blade and an object to be cut. The angle change unit is configured to change the angle between a first angle during a non-cutting time and a second angle at which the blade is tilted during a cutting time so that the second angle is rendered smaller than the first angle. The first abutment limits a swinging movement of the blade while the first angle is made by the blade and the object. The second abutment limits the swinging movement of the blade while the second angle is made by the blade and the object. The angle between the blade and the object is changed from the first angle to the second angle by resistance to which the blade is subjected from the object with the relative movement of the blade.
