Abstract: 1284955 Folding cameras POLAROID CORP 3 June 1970 [13 June 1969] 26851/70 Heading G2A A folding camera has two housing sections movable relative to each other between a folded position and an extended operative position, one section 12 housing a photo-sensitive element and the other section 14 housing an objective 66 and a mirror 70 which in the operative position reflects light passing through the objective on to the photo-sensitive element. The rear section 12 is designed to accommodate a series of selfprocessing film units. The camera unfolds from the completely closed position of Fig. 1 (not shown) through the partially opened position of Fig. 3 (not shown) to the completely opened and operative position of Fig. 2 (not shown), this latter position being shown in more detail by Fig. 8. The forward section 14 comprises two separate portions 54, 56, each mounted by a linkage system on the rear section 12, the two linkage systems being separate but coupled together. In the folded position these two portions lie physically separated, for compactness, but in the unfolded position they are brought together, one underneath the other as in Fig. 8, and mutually positioned by locating pins 106. Sections 12 and 14 are connected by a light-tight bellows 64. The forward section 14 contains the objective lens 66 and a mirror 70 which, in the operative position shown, is disposed at 45 degrees to the lens axis and reflects light coming therethrough down to the photo-sensitive sheet. The mirror 70 can be moved out of the light path to allow of view and range finding, as in reflex camera arrangements. A further mirror 118 behind mirror 70 reflects the incoming light to another mirror 120 and thence through an eyepiece lens (126) in a housing 127 (see also Fig. 7 not shown). These components are mounted on a plate 128, and are biased rearwardly by a spring 130 into an extended operative position such that mirror 118 will not interfere with mirror 70 when the latter is also in its operative position.
