摘 要 附 图:

摘 要:

A camera has two or more alternative focusing devices. As shown, one of three focusing devices (14, 16 and 18) is selected by positioning a toggle switch (20) in one of three respective positions I, II and III, switch (20) being biased to

position II. A single IR beam is emitted at aperture (28) and a bounced beam is received (a) at apertures (30) and (32) from distant subject (22) using device (14, (b) at apertures (30) and (34) from near subject (24) using device (16) and (c) at apertures (32) and (34) from intermediate subject (26) using device (18). Two or three emitted beams may be employed instead of a single emitted beam. 主权项:
