Slide projector

A  is a type of electro-mechanical equipment used for projecting the image printed on a slide onto a projection screen. These images are used as an educational aid. The projector has a lens for transmitting the image, a slot for ejecting and loading a set of slides, and a hand lever for controlling the projector. The projector has an independent power source. Slide projectors are associated with tables and projection screens and are sometimes accompanying them. These projectors are used in the Vault-Tec Vaults.

The slide projectors in the Vaults are communally owned and were passed from one generation to the next. The expectation of Vault residents is that the slide projectors will be properly cleaned and maintained to ensure their availability.
