Patent ID: 7222770

Claim:
An electric stapler comprising: a forming mechanism for forming a linear staple in a gate-like shape; a driver mechanism for injecting the staple formed in the gate-like shape; a clinching mechanism for clinching two leg portions of the staple in the gate-like shape; an anvil supporting member; an anvil attached to the anvil supporting member pivotably in a front and rear direction for supporting a middle portion of the linear staple in forming the staple; and an anvil guide mechanism; wherein the anvil supporting member is integrated to the driver mechanism and formed such that the anvil supporting member and the anvil are moved up and down integrally with the driver; wherein the anvil guide mechanism maintains the anvil in a state of being projected to a path of the driver at an end face of the driver immediately before the anvil is brought into contact with an object of stapling, and thereafter escapes the anvil from the path of the driver by inclining the anvil frontward, and the anvil guide mechanism maintains the anvil in a state of being projected to an upper side of the end face of the driver, and thereafter escapes the anvil from the path of the driver by inclining the anvil forward, and the anvil supports a horizontal crown portion of the staple immediately before finishing to strike the staple by the driver.
