The technical scheme in the invention for solving the technical problem is：Rapier loom accounter device, the meter
Counting apparatus include casing, rotary transformer and decoding plate, and the rotary transformer and decoding plate are respectively positioned on the casing internal, institute
The rotary shaft for stating rotary transformer is located at outside casing through the through hole on the casing, and the rotary transformer is translated with described
Code plate correspondence connects, and two binding posts are provided with outside the casing, and the binding post is corresponding with the decoding plate
Connection.
Preferably, the casing is a cylindrical drum, the central shaft of the rotary shaft of the rotary transformer and the cylindrical drum
Coaxially.
Further, the one end in the cylindrical drum arranges an annular boss, is provided with along it on the annular boss
