Abstract
PURPOSE: To realize the plate making with high quality without picking up the undesired area although some variance of measurement exists between a scale panel and a card, by using a shadow taking tape provided on the rear surface of a transparent original board, a position control mechanism for the shadow taking tape and a monitor means for the tape position respectively.
CONSTITUTION: A scale panel 1 is put on the original board glass 5 with the scale card set to the rear side, and the guides 6 and 7 perform the positioning of the panel 1. The shadow taking white tapes 8a and 8b of the inter-row gap can move along the rear surface of the glass 5. The dials 11a and 11b control the position of the inter-row gap. The positions of the tapes 8a and 8b are reflected to a position control mirror 10 and can be monitored from outside of the main body 30. As a result, the fine adjustment is possible for the positions of the tapes 8a and 8b by means of the dials 11a and 11b while looking at the positions of the tapes 8a and 8b after opening a shutter 16. After confirming the positions of the tapes 8a and 8b, the plate making is performed by an image pickup for the original.
