SLIDE PROJECTOR COMPRISING ACTUATING MEANS

摘要

A slide projector having a remote control unit which is removable engageable with the slide projector. When the control unit is disengaged from the projector, it is removably engageable with an accessory which can be a further control or indicating device. Electrical contacts on the control unit electrically communicate with contacts in an aperture located on the projector and also a similar aperture located on the accessory. Thus, during remote control operations, an additional function or indication can easily be added to the control unit.
