A cutting device includes a cutting blade, a receiving block, a motor, a cutting blade movement mechanism, and a receiving block movement mechanism. The cutting blade includes a blade portion. The receiving block includes a contact surface including a first contact surface and a second contact surface. The motor is configured to rotate in a forward direction and a reverse direction. The cutting blade movement mechanism supports the cutting blade and is configured to move the cutting blade between a separated position and a contact position in concert with a rotation of the motor when the motor rotates in a forward direction and when the motor rotates in a reverse direction. The receiving block movement mechanism is configured to move the receiving block from a first opposed position to a second opposed position in concert with the rotation of the motor.
