Hira-Karakuri: The Basic Matchlock Mechanism

The hira-karakuri is the most basic matchlock design. The mainspring of a hira-karakuri lock is a simple, U-shaped length of metal, usually iron or brass, that is mounted on the exterior of the gun’s lock plate. The spring and serpentine arm are kept under tension by a lever called a “sear,” which connects to the trigger. Pulling the trigger releases the sear, freeing the gun’s serpentine arm to snap down onto the priming pan. The burning match cord ignites the priming powder, and the priming powder ignites the main charge inside the barrel, expelling the musket ball.

Most guns used in the sixteenth century had hira-karakuri locks. The locks were simple and relatively cheap to make, but their springs tended to weaken with repeated use.

平機關——最基礎的火繩槍機

平機關是最基礎的火繩槍機零件，其主要驅動裝置是一個簡單的U形鐵條或黃銅條，加裝在槍機外側。簧板和S形的蛇杆由一個與扳機相連的控制杆「擊發阻鐵」固定並繃緊。扣動扳機，釋放擊發阻鐵，蛇杆鬆開，向前擊中火藥池。陰燃的火繩引燃引火藥，引火藥點燃槍膛中的主火藥，推動彈丸自槍口飛出。

16世紀的槍械大多採用平機關。這種槍機裝置構造簡單，雖然反復擊發之後簧板會逐漸失去彈性，但造價相對低廉。
