Contact 801-iAnd the number of the conductive contacts 60-iThe same number of contact points 801-iIs positioned in a manner to be in contact with the conductive contact 60-i(e.g., spring pins). Since the piezoelectric jacquard mounted on the guide bar 90 may be plural, the contact points 801-i on the wiring board base plate 80 fixed to the guide bar 90 may be plural. The wiring board bottom plate 80 may be attached to the guide bar 90 in sections (not shown) for ease of installation and signal section entry.
