Claim:
A lock mechanism of a table of an electric stapler comprising: a table, pivotally supported by a main body frame of the electric stapler, and including a clincher mechanism that pivots to bend a leg portion of the staple penetrated through the sheets along the sheets, and a wing piece formed on each side of the table and extending downward along each side of the main frame body; locking means formed between each wing piece of the table and the main body frame, wherein a pivoting force in an opening direction of the table is hampered by engaging the locking means with each wing piece of the table; wherein each locking means comprises a lock plate including a locking pin engageable with the wing piece at one end thereof and supported by the main body frame at other end side thereof, and wherein, by engaging the locking pin with the wing piece to hamper the wing piece from being pivoted, the pivoting force in the opening direction of the table is hampered, wherein the locking means further comprises: an operating piece formed at the lock plate; and an operating cam arranged to be brought into contact with and to be separated from the operating piece, wherein, when the operating cam is rotated to separate from the operating piece, by rotating the lock plate by a spring, the locking pin is engaged with the wing piece, the wing piece is hampered from being pivoted and the pivoting force in the opening direction of the table is hampered.
