A turntable for storage disk drive apparatuses includes a plate member made of a ferromagnetic material and a central resin member arranged at the center of the plate member and formed by injection-molding a resin. The central resin member includes a disk guide portion provided on an upper surface thereof to guide a central hole of a disk and a plurality of gate recess portions indented upwards from a lower surface of the central resin member. The gate recess portions include ceiling surfaces positioned higher than the plate member. The ceiling surfaces include a plurality of gate cut portions formed in an injection molding process.

A turntable for a storage disk drive apparatus includes a plate member made of a ferromagnetic material and a central resin member arranged at the center of the plate member and formed into a single member by injection-molding a resin. The plate member includes a peripheral plate portion and a central plate portion positioned higher than the peripheral plate portion. The central plate portion includes a plate center hole defined at the center of the plate member. The central resin member includes a resinous cylinder portion extending through the plate center hole and defining a resin central through-hole, a disk guide portion arranged to guide a disk center hole, and a resinous connector portion arranged above the central plate portion to interconnect the resinous cylinder portion and the disk guide portion.

A turntable for a storage disk drive apparatus includes a plate member made of a ferromagnetic material and a central resin member arranged at the center of the plate member and provided with an outer peripheral portion positioned above the plate member. The central resin member includes claws extending downwards from the outer peripheral portion and claw position holes overlapping with the claws in the direction parallel to the center axis of the central resin member. The claw position holes include inner surfaces spaced apart from an edge of the plate member. The inner surfaces are defined by the resin. The central resin member includes a resin layer extending in the direction perpendicular to the center axis. The resin layer exists between the portion of the edge of the plate member around the claw position holes and the claw position holes.

A position information system () obtains position information (latitude and longitude) of a dispatch location from a telephone number/address DB () or an address/position information DB () based on the sender telephone number of a telephone () of a customer or the like requesting the dispatch. A display control portion () obtains map images of the vicinity of the dispatch location from a map DB () based on the position information, and displays these on a display () with the display location in the center. Also, position information and the current status of each dispatch staff member is obtained at any time from portable terminals () of the dispatch staff members, and based on this information, markings representing the dispatch staff members in the vicinity of the dispatch location are displayed on the map, allowing a staff member to be dispatched to be quickly and appropriately selected.
