A flexible flat cable (FFC) includes a first insulation layer, at least one pair of conductors, a plurality of low-k dielectric layers, two second insulation layers, and at least one shielding layer. The pair of conductors is located within the first insulation layer. Each pair of conductors includes a plurality of first conductors, and the first conductors are axially extending and arranged in parallel. The low-k dielectric layers are embedded in the first insulation layer. Each of the pair of conductors or each of the first conductors is covered and surrounded with one low-k dielectric layer. The two second insulation layers are located on two surfaces of the first insulation layer. The shielding layer is located on the two second insulation layers opposite to the first insulation layer.

A first leading end plate and a first rear end plate are provided at an upper part of a rotary table. When a conductor piece contacts the first leading end plate, a first contact detection sensor detects a contact of the conductor piece, and transmits a contact detection signal to a storage control unit. Upon receiving the contact detection signal, the storage control unit drives an air supply device for a predetermined period to spray air toward the conductor piece from a first air nozzle. The air spray brings the conductor piece into a tilted state with the rear end thereof moved downward. Even when the conductor piece contacts the first leading end plate and rebounds, the rear end thereof contacts an inner wall surface of the first rear end plate, thereby preventing the rear end of the conductor piece from getting over the first rear end plate.

A wiring member includes a wire-like transmission member, a holding member, and a connector. The holding member is configured to hold the wire-like transmission member two-dimensionally in a positioned state. The connector is attached to an end portion of the wire-like transmission member. The connector is provided with an orientation recognition mark.

A shielded flat cable includes multiple flat conductors arranged in parallel, a lower insulating layer provided on lower surfaces of the multiple conductors, a lower shield layer provided on a lower surface of the lower insulating layer, a lower protective layer provided on a lower surface of the lower shield layer, a lower contact portion that is exposed from the lower protective layer and provided to contact a second contact member of the connector, and that is electrically coupled to the lower shield layer, a terminal in which the multiple conductors are exposed at an end, and a reinforcing plate provided on the lower surface of the lower insulating layer and the lower surfaces of the multiple conductors at the terminal. The multiple conductors extend along the lower insulating layer and the reinforcing plate, and the lower contact portion and the terminal overlap in a side view.
