Abstract
In a guide apparatus for a copy master, guide elements are provided which define a transport plane of the copy master and which comprise lateral walls located essentially perpendicular to the plane of transport of the master and approximately parallel to the direction of copy master transport. The lateral walls guide the lateral edges of the copy master. A detector is further provided to detect the information applied near lateral edges of the copy master. The lateral walls of the guide apparatus are laterally adjustable in case of variations of the width of the copy master in the plane of transport.
Claims13
Guide apparatus for a photographic copy master comprising:
- transport means for transporting the copy master, said transport means defining a transport plane of the copy master and further including:
- guide elements having lateral walls essentially perpendicular to the transport plane of the copy master and approximately parallel to a direction of copy master transport for guiding the copy master at its lateral edges, said lateral walls being laterally movable relative to the transport direction of the copy master in the plane of transport;
- detection means to detect information applied to the copy master near its lateral edges;
- a plate spring having a free end connected with at least one of said lateral walls, said at least one lateral wall being movable laterally against a reset force of the plate spring;
- a support surface for supporting a lateral portion of the copy master, the lateral walls being approximately perpendicular to and connected with said support surface;
- at least one diaphragm hole for blocking out all of the light transmitted through the lateral portion of the copy master but that part of the light passing through the diaphragm hole;
- and
- optical means located in a light path of said light transmitted through the lateral portion of the copy master for conducting the light having passed through the diaphragm hole.
