Thank you for viewing. This is a Casio ultra-thin projector, the XJ-S47. It's incredibly thin at 32mm, and its dimensions are B5 size, so it fits easily into a backpack or briefcase. It's a convenient mobile item, as it can project data from a USB memory stick without a PC. It has been used to some extent (1,178 hours of use), but there are no operational problems. There are a few scratches on the surface of the main unit, although they are not very noticeable. *See the red circles in the photos for annotations. Below are the specifications.
