A cutting device characterised by: a receiving block configured such that an object to be cut (9, 9A, 9B) is arranged thereon; a cutting blade that includes a blade portion, the cutting blade being configured to move between a separated position and a contact position via a clamping position, the separated position being a position in which the blade portion is separated from the receiving block, the contact position being a position in which the blade portion is in contact with the receiving block, and the cutting blade being configured, when the cutting blade is in the clamping position, to clamp the object between the blade portion and the receiving block; a first rotating member coupled with the cutting blade, the first rotating member being configured to cause the cutting blade to move from the separated position to the contact position via the clamping position, by the first rotating member rotating in a specified direction from a separated rotation position to a contact rotation position via a clamping rotation position; an elastic member provided on the first rotating member; a DC motor; and a second rotating member configured to rotate in accordance with rotation of the DC motor, the second rotating member being configured to cause the first rotating member to rotate from the separated rotation position to the clamping rotation position by the second rotating member rotating in a first direction from an initial rotation position to a first intermediate rotation position while being in contact with the elastic member, and the second rotating member being configured to increase an amount of elastic deformation of the elastic member and urge the first rotating member in the specified direction by the second rotating member rotating in the first direction from the first intermediate rotation position while being in contact with the elastic member. a receiving block configured such that an object to be cut (9, 9A, 9B) is arranged thereon; a cutting blade that includes a blade portion, the cutting blade being configured to move between a separated position and a contact position via a clamping position, the separated position being a position in which the blade portion is separated from the receiving block, the contact position being a position in which the blade portion is in contact with the receiving block, and the cutting blade being configured, when the cutting blade is in the clamping position, to clamp the object between the blade portion and the receiving block; a first rotating member coupled with the cutting blade, the first rotating member being configured to cause the cutting blade to move from the separated position to the contact position via the clamping position, by the first rotating member rotating in a specified direction from a separated rotation position to a contact rotation position via a clamping rotation position; an elastic member provided on the first rotating member; a DC motor; and a second rotating member configured to rotate in accordance with rotation of the DC motor, the second rotating member being configured to cause the first rotating member to rotate from the separated rotation position to the clamping rotation position by the second rotating member rotating in a first direction from an initial rotation position to a first intermediate rotation position while being in contact with the elastic member, and the second rotating member being configured to increase an amount of elastic deformation of the elastic member and urge the first rotating member in the specified direction by the second rotating member rotating in the first direction from the first intermediate rotation position while being in contact with the elastic member.
