ABSTRACT:
The invention discloses a combination comprising a storage case, a support stand, and one or more work surfaces. The storage case includes: a stand compartment in which to house the support stand and ancillary equipment as required, and a light compartment to provide a light source. The support stand includes legs, that can be folded for storage in the support case, and that can be telescoped for positioning a work surface at various heights and angles. The telescopic action may be electro-hydraulically operated. A choice of work surfaces enables the light compartment to be used as a light table or as a display screen for various types of image projection.
