According to the present disclosure, a tape feeder includes a main body that is attached to a component mounter and has a tape traveling path which is a traveling path of a carrier tape; and a sprocket that is provided in the main body, causes an outer peripheral tooth to engage with a feed hole of the carrier tape, and rotates so as to perform pitch feeding of the carrier tape on the tape traveling path. The tape feeder includes a lock mechanism that has a press operation unit operated with pressing force, locks the sprocket in the main body in a state where the press operation unit is not operated, and unlocks the sprocket in a state where the press operation unit is operated.

A plurality of marks (11) equidistantly provided on both side edge parts (1a) of a long medium (1), a plurality of first indicator holes (12) equidistantly given on at least one of the side edge parts (1a), and a plurality of second indicator holes (13) given on at least one of the side edge parts (1a) on a straight line different from a row of the first indicator holes (12) at spacings shorter than spacings of the first indicator holes (12) are provided, and the second indicator holes (13) are each provided to a side of a trailing-end mark (11b), and each gradually comes closer to a leading-end mark (11a) as the long medium (1) runs toward a trailing end.

There is provided a component supply device for supplying a component to a component mounter, including: a transporter that transports a carrier tape in which the component is stored and of which an upper surface is sealed with a cover tape, along a transport path; a peeler that peels off the cover tape from the carrier tape via an opening portion disposed above the transport path; and a cover that makes an open state of the opening portion variable. The cover sets the open state of the opening portion to be any of a first open state allowing the peeler to capture the cover tape and a second open state where an opening size of the opening portion is smaller than that of the first open state and passage of the cover tape peeled off from the carrier tape is not impeded.

A feeder, for which carrier tape is reliably inserted to a specified position without contacting engaging protrusions of sprocket, is provided. The feeder includes an entrance retaining member that pushes the carrier tape inserted into a tape insertion section towards a tape feeding path, a rotatable lever that raises the entrance retaining member when the carrier tape is inserted into the tape insertion section, and a contact prevention device that prevents contact between the carrier tape inserted into the tape insertion section and the engaging protrusions when the entrance retaining member is raised by the rotation of the lever.

An electronic component supply apparatus that transports a component supply tape which has accommodation sections and sprocket holes and which accommodates an electronic component in each of the accommodation sections and is covered with a cover tape, to a component picking-up position and that supplies the electronic component to a component mounting apparatus, the electronic component supply apparatus includes a sprocket hole detecting unit that detects a sprocket hole on the upstream side on a transport path from the component picking-up position; an electronic component detecting unit that detects an electronic component accommodated in the accommodation section on the transport path on the upstream side from the component picking-up position; and a component presence/absence determining unit that determines presence or absence of an electronic component in the accommodation section based on information from the sprocket hole detecting unit and information from the electronic component detecting unit.

A glass ribbon coated with a flexible material, the flexible coating forming a flexible web portion that extends from an edge of the glass ribbon at least one millimeter. The flexible web portion can be used to facilitate handling of the glass ribbon in a manufacturing process, and may include registration markings, or perforations, that further facilitate precise positioning of the ribbon.
