A coil nailer aligns the releasing direction of a door latch with the door opening and closing direction such that a door latch is released to open the door by one touch of a left hand thumb, a contact arm is easily coupled with and separated from a contactor to prevent the contact arm from separating from the contactor and to easily exchange the contactor, a guide device in a magazine filled with various sized nails is moved to precisely guide the nails, and a measuring device measuring intervals between shingles is attached to the magazine such that the shingles are positioned at predetermined intervals without a separate measuring device. Since the plate supporting nails is lowered or lifted according to lengths of the nails, the nails can be effectively guided, the interval between lower and upper waterproof sheets can be measured when attaching shingles and waterproof sheets.
