Abstract: An apparatus for storing an electronic component, the electronic component having a first surface and an opposite second surface, the apparatus includes a first film having a pocket that stores the electronic component and wherein the pocket has a protrusion at a bottom and wherein a top of the protrusion contacts with the second surface of the electronic component, and a second film covering the pocket and wherein a part of the second film is stuck to the first surface of the electronic component by a pressure difference so that the electronic component does not move freely.

Abstract: A bidirectional optical communication system employing a living line and a standby line. One of a master unit and a slave unit has a photoswitch for switching between the living line and the standby line and the other has a photocoupler for collecting the living line and the standby line. When deterioration in communication state of the living line is detected on the side having the photoswitch, the photoswitch on that side is switched to use the standby line.

Abstract: A method for packaging electronic components wherein each of the electronic components having a first surface and an opposite second surface is placed in each of a plurality of pockets of a first film, bottom of each of the pocket has a protrusion that contacts the second surface of the electronic component, the pockets of the first film with the electronic components therein is covered with a second film, a pressure difference between the pockets as covered with the second film and an exterior of the pockets is created so that part of the second film is stuck to the first surface of each electronic component by the pressure difference to secure the electronic components within the pockets.

Abstract: A carrier reel according to the present invention is constituted by a flange portion having a first surface and a second surface which is opposed to and substantially parallel to the first surface, and a hub portion which is provided between the first surface and the second surface and to which the flange portion is connected. A bearing portion at which a shaft used for taking out each electronic component after carriage is supported is provide to the hub portion, and spaces for accommodating therein a drying agent, i.e., drying agent accommodating portions are formed at the part of the hub portion except the bearing portion. The drying agent is accommodated in the drying agent accommodating portions. The carrier reel having the drying agent accommodated therein is put in a damp proof bag to be sealed. The sealed damp proof bag is then packaged to be carried.
