Abstract
PURPOSE: To enable correct exposure to be always obtained by driving a shield plate subsequently according to the preset time to perform test printing and exposure-recording the exposure time on photographic paper.
CONSTITUTION: Now, when the times of a number of steps are set and inputted from a keyboard 1, they are stored in a memory element 2. Next, when a start switch 9 is turned ON, an enlargement projecting lamp 10 is lighted by the signal from a control part and a cunter 4 integrates the elapsing time. The first set time is then exposed on photographic paper 14 by a number display device 12. As the time elapses and when the storage content and the integrated time of the counter 4 coincide, a signal is sent from a comparator 5 to a control part 6 which in turn causes a shield plate 11 to be driven by a drive part 8, so that the photographic paper is exposed 15 and the time is exposure-recorded 13.
