ABSTRACT:
A still projector having a closure plate covering a housing aperture providing access to a projection lamp has a storage chamber within the housing positioned to be covered by the closure plate when the closure plate closes the aperture and to be accessible when the closure plate is removed from the aperture. The storage chamber is shaped to receive and store a spare projection lamp and preferably also a lamp changing tool. The closure plate is preferably a slide plate fitting flush with an exterior surface of the housing and extending over a cooling fan and its drive motor. The closure plate prefereably has air passage slots located over the fan, and the storage chamber is preferably formed as a depression in the projector housing over the drive motor.
