【 ホッチキス・hotchikisu 】stapler
Also called ホチキス (hochikisu). Some people in the northern part of Japan call a stapler ジョイント (jointo) or ガッチャンコ (gatchanko). The word ガッチャン (gatchan) is an onomatopoeia for a latching or clamping sound.
ホッチキス became a generic term, taken from the first stapler that was imported from America, the "Hotchkiss No.1," by the E.H.Hotchkiss Company in the early 1900s.
The staples or stapler pins are called 針 (しん shin; as in needle).
To staple with a stapler is ホチキスで留める。(hochikisu de tomeru)
