Abstract
Abstract An apparatus for use in a photocomposing machine for placing character images in side by side relationship on a recording medium, which apparatus comprises two periscopes arranged such that the exit axis of the first periscope coincides with the entrance axis of the second periscope and in which both periscopes are swingable about axes that coincide with the entrance axes of the respective periscopes.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
239 words
Apparatus for displacing the place of imaging on a recording medium in a photocomposing machine with the use of a mirror system arranged in the optical axis of an imaging system between a character support and the recording medium, which system includes four mirrors inclined 45° to the optical axis and directed in pairs parallel to each other, the position of at least one mirror with respect to the recording medium as well as the positions of the mirrors with respect to each other being variable for displacement of the place of imaging in particular along a line in such manner that the length of the optical path between the recording medium and the mirror facing the character support remains constant, characterized in that each pair of parallel directed mirrors (3, 4 and 6, 7 respectively) are connected on a common support (5 and 8 respectively) to form individual periscopes, that the first periscope (3, 4, 5) facing the character support (1) is swingable around its entrance axis (a) so that, regardless of its position, it is always directed, to the same position on the character support (1), that the second periscope (6, 7, 8) which faces the recording medium (2) is swingable about its optical entrance axis (c) which coincides with the exit axis of the first periscope in such a manner that the longitudinal axes (b, d) of the periscopes are swingable with respect to each other.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
37 words
Apparatus according to claim 1, characterized by the fact that the mirror (7) of the second periscope (6, 7, 8), which mirror faces the recording medium (2), is guided for displacement parallel to the line direction (12).
Claim 4
Dependent Claim
22 words
Apparatus according to claim 2, characterized by the fact that an objective lens (13) is arranged on one of the supports (8).
