Cutting apparatus

A cutting apparatus configured to cut a sheet bundle, the cutting apparatus comprising:

• a first knife having a first end face formed on a first base end on the opposite side of a first tip in a vertical direction, and at least one fastening hole formed in the first end face so as to extend in the vertical direction and having an internally threaded inner circumferential face;
• a second knife fixed at a predetermined position;
• a fixing member having a second end face arranged facing the first end face in the vertical direction, and at least one fitting groove extending in the vertical direction and opened on one end side in a first direction;
• a fixing mechanism having at least one fastening bolt having an externally threaded outer circumferential face, the fixing mechanism being configured to detachably fix the first knife at a fixing position of the fixing member by fastening the fastening bolt into the fastening hole with the first end face and the second end face being in contact with each other;
• and
• a motion mechanism configured to move the fixing member between a non-cutting position and a cutting position in a vertical direction to perform switching between a non-cutting state where a first tip of the first knife is spaced apart in the vertical direction from a second tip of the second knife and a cutting state where the first tip passed has passed by the second tip,
• wherein the first direction is orthogonal to the vertical direction and is a direction in which the first tip and the second tip come close to or move away from each other, and
• wherein the fixing mechanism is configured to adjust the fixing position in the first direction by sliding the fastening bolt within the fitting groove.
