Claims

[Scope of Claim for Utility Model Registration] A thread whose lower end is guided by one warp thread and is constantly pulled under the downward force of a spring; a drive pulley whose lower end can be selectively pulled up; a thread thread connected to both ends of the thread thread for suspending the pulley through a groove of the drive pulley and selectively driving the pulley up and down; a pair of vertical hooks which can be raised and lowered independently, and a pair of vertical hooks which are always raised and lowered in opposite phases to selectively engage with and drive the vertical hooks up and down; In the jiacard device equipped with a knife, the pair of vertical hooks are given elasticity so that their upper ends are always separated from each other, so that the outer hook portion of each hook is in contact with the knife in this separated position. The lower end of the knife and the upper end and hook of the corresponding vertical hook are adapted to engage with each other, and the lower end of the knife and the corresponding upper end and hook of the vertical hook are adapted to engage the lower end of the knife and the corresponding upper end and hook of the vertical hook. A cam surface and a cam follower surface are respectively formed to exert a cam effect to push the hook back inward when sliding with the hook, and a permanent magnet is attached to the appropriate position on the inner surface of each of the pair of vertical hooks. At the same time, a solenoid-wrapped core is arranged at a position between the hooks corresponding to the permanent magnet when these hooks are at the lowest end position of the lifting stroke,
A jiacard device characterized in that an electric circuit is provided for energizing the solenoid with a pulse at a polarity that repels the corresponding permanent magnet when selecting warp threads.
