  • Patent number: 12103153
    Abstract: A stapler includes a staple striking-out unit, a staple leg bending unit, and a connector that connects the staple striking-out unit and the staple leg bending unit. The staple leg bending unit includes a clincher having a guide surface for bending the staple legs, and a clincher guide having a sandwiching portion. The clincher guide is configured to move in a first direction to displace a distance between the guide surface and the sandwiching portion. The clincher is capable of being located at a lower end position where the guide surface is farthest from the sandwiching portion in the first direction. The lower end position is a position where a tip ends of the staple legs are in contact with the guide surface and a gap is formed between an upper surface of the sheet sandwiched by the sandwiching portion and a staple shoulder portion of the staple.
