The present invention relates to an air supply device, and more particularly, to an air compartment for partitioning an inner space of a housing into various spaces in a longitudinal direction, an air discharge control unit for partitioning between an air fan and a filter, and the air fan itself. An air generation control unit is provided to adjust the air generation amount in the width direction of the housing so that air is generated in each compartment, and the generated air is evenly discharged upward for each compartment or blocks air discharge from a specific compartment. Instead, the air volume may be increased and discharged to another neighboring compartment, and the air generation direction with respect to the width direction of the housing may be adjusted. For example, in the case of the plate glass conveying apparatus, it is located above the cover and is horizontal. To the desired part of the pane, a thin flat plate structure that is transported along the direction To the air supply to and about the air supply apparatus so that this is correct and stable glass in accordance with the transfer enable is capable of freely adjusting the flatness of the plate glass is being transferred to be maintained constant.

It is a transfer device used to transfer plate glass to the inspection part or other process lines on inspection equipment for inspecting defects of thin plate glass, which is conventionally used for LCD PDP.
