Abstract: 1464516 Optical projection apparatus MARVIN GLASS & ASSOCIATES 1 Oct 1975 [20 Nov 1974] 40133/75 Heading G2J [Also in Division A6] A target game comprises a target projector 28, Fig. 2, for projecting an image of either a target 12, Fig. 1, or a "hit" on to a screen 14, and a hit actuating member 38 movably mounted on the projector and operative to move means 76 carrying the images from its "normal" target projecting position to its "hit" projecting position, a movably mounted gun assembly 122 including a trigger assembly having a striking portion 184 to engage the hit actuating member 38 and move the image carrying means 76 whenever the trigger assembly is actuated and the striking portion and the hit actuating member are aligned, and means 266, Fig. 4, for moving the target projector to move the projected image over the screen and simultaneously and correspondingly move the hit actuating member 38 relative to the striking portion 184. Target-projector The target 12 or a "hit" is projected by means 28, Fig. 2, in the base 18. The projector 28 can be oscillated about pivots 58 by a rod 68 moving in a slot 70. The pivots 58 are mounted on a support movable angularly on a vertical post 50 against the bias of a spring (62). The screen image is formed by a bulb 74, a slide 92 in the pivoted holder 76 and lenses 84, 86 in a rotatable focus-adjusting barrel 78. The holder 76 also carries a slide 96 of an explosion, or "hit", and is tilted to change the slide projected when a lever arm 178 carrying the spring 184 moves a slide 104 having a slot 116 embracing a projection 102 on the holder. Gun projector The gun 30, Fig. 2, is rotatable on pivots on a rotatable pillar 130. A bulb 146, a slide 150 and a lens 144 project a "hit area" image on to the screen, i.e. to represent the point on the screen which would be engaged by a projectile. Target-projector moving means The motor 266, Fig. 4, rotates a cam member 200, having an upper annular cam surface 210 engaged by the rod 68 to tilt the target projector up and down, and a peripheral cam surface 220 to oscillate a sector gear 228 engaging a gear 54, Fig. 2, thus oscillating the target-projector. Noise production The motor 266, Fig. 4, also rotates a doublearmed striker 236 co-operating with a noiseproducing spring leaf 234 attached to a sound-box 242. Whenever the box 242 is pulled towards the striker by a Bowden cable 258 operated by the gun-trigger 166, the noise of gun-fire is produced. The intermittent engagement of the striker and the leaf 234 also completes a circuit to illuminate the  gun-bulb 146. Operation and timing To start the motor 266, Fig. 4, a button 322 is depressed to cause bending of a contact leaf 304, 306 and engagement thereof with a contact 310. When the cam 200 has completed a revolution, the bend of the leaf 304, 306 enters a recess (312) in the cam and disconnects the circuit. When the gun is pointing at the target, pressure on the trigger pivots the arm 178, Fig. 2, and the spring 184 is in position to engage a projection 108 on the slide 38 to pivot the holder 76 and cause the "explosion" to be projected.
