Abstract
1465319 Slide projector ERNST LEITZ WETZLAR GmbH 4 April 1974 [14 May 1973] 14931/74 Heading G2J A projector has a motor 13 for driving magazine 2 and sensing elements 9 and 10 responsive to the position of the magazine to control motor 13 so that when the first or last slide compartment is located at the slide changing plane 6 only forward or reverse movement respectively of the magazine is possible and when an intermediate slide compartment is located at the plane 6 movement in either direction is possible. As shown, the sensing elements 9 and 10 are selectively depressed by the magazine to close switches 11 and 12 which connect the motor 13 to a power source via diodes 14 and 15. A manual switch 17 selects the direction of magazine movement. In Fig. 2 (not shown), an additional sensing element (19) is provided at the plane 6 and the three sensing elements (18, 19, 20) are connected to indicator lamps (24 to 27); lamp (24) being lit when the last slide compartment is at the plane 6 and lamps (25, 26, 27) respectively being lit when the first slide compartment is just in front of, actually at, and just past the plane 6.
