Abstract

1,060,425. Photographic printing apparatus. GRETAG A. G. March 13, 1964 [March 13, 1963], No.10806/64. Heading G2A. A photographic printing apparatus has a series of components defining the optical reproducing system, each component being selectable from a plurality of different components of the same kind, the series being selectable in accordance with the size of positive and negative chosen, and an electrical circuit whereby the component selected is compared with the component desired, and, if it is different, a safety device is actuated. In the form shown, light from source 1 passes first through a condenser lens. Two such lenses 3a, 3b, are carried on a disc 3, so that either can be rotated into the light path. The light beam then passes through one of three differently sized negative holders 4a, 4b, 4c, on a disc 4, and one of three objectives 5a, 5b, 5c having different focal lengths, any of which can be rotated into the light path. The positive print is made on a strip 7 of light-sensitive material, in front of which is a masking disc 6 having three differently sized apertures 6a, 6b, 6c, thus giving a choice of three finished print sizes. On each of the disc shafts 8a, 9a, 10a, 11a are respective switch boxes 8, 9, 10, 11, all connected with a main control and comparator box 13. With the arrangement shown, three different enlargement sizes are available, and the one selected is registered by pressing the appropriate switch 14. If the various components on discs 3, 4, &c. have been incorrectly set for this particular enlargement, a signal lamp is lit, and a safety device prevents the printing step from being carried out. The electrical circuitry for effecting this control is set out in more detail in Figs. 2 and 3 (not shown), and may also include servomotors for automatically correcting any error.
