Abstract: There is provided an ordering and order receiving system for fish and shellfish, capable of achieving an ingenious transaction type that can be performed due to an electronic transaction using computers. When each of the ordering clients inputs ordering data into the order receiving server, the server forms order receiving data based on customer information according to the ordering data and commodity information on fishes and shellfishes for which an order has been received, and also forms stocking data and shipping data based on the order receiving data so as to output the pieces of data to a management client in fish and shellfish management section.

Abstract: A disk drive includes base with a spindle motor, first and second rockers and first and second sliders. The spindle motor has a turntable to mount a disk. The first and second rockers rock so as to pivot about fulcrums substantially parallel to the turntable. The first rocker pulls in the disk, inserted externally, to a position where the disk and motor have their centers aligned. The second rocker unloads the disk from the position to a point where the disk is exposed partially. The first and second sliders are engaged with the first and second rockers to make them pull in and unload the disk, respectively, and reciprocate substantially parallel to the turntable. The rockers and sliders are located under the turntable. The slider(s) support(s), raise(s) and lower(s) a side face of the base through the reciprocation.
