  • Patent number: 9084385
    Abstract: An object of the invention is to provide an electronic component mounting device and a work method of the electronic component mounting device, capable of ensuring safety of an operator who accesses a work line through a door portion, and avoiding reduction of workability. A space defined by a base (11) and a cover member (14) is partitioned by a partition member (15) to define a plurality of work line storing spaces (SP1). A plurality of work lines (12) are stored in the respective work line storing spaces (SP1) individually. When any of a plurality of door portions (14a) provided in the cover member (14) so as to allow an access to an inside of the respective work line storing spaces (SP1) is opened, an operation of a work line (12) stored in a work line storing space (SP1) accessible through the opened door portion (14a) is stopped.

  • Patent number: 8999108
    Abstract: In the separation of a cover tape 15e from a carrier tape 15 performed by a cover tape separating mechanism 50, a cover tape 15e, which is separated from a base tape 15a by a separating blade edge 51f, comes into contact with a concave conical surface 52c, so that one side portion of a cover tape 15e is bent toward the other side portion; and the bent cover tape 15e is pressed against a guide surface 32s from below while the carrier tape 15 is guided to a pick-up position. Accordingly, the cover tape 15e is folded on the base tape 15a in a flat shape.
