Abstract: PURPOSE:To correct the amount of exposure of a determining device for the amount of printing exposure finely and accurately by calculating the amount of printing exposure on the basis of a photometric value obtained by scanning on a film screen and calculating the corrected amount of exposure from a specific equation. CONSTITUTION:The photometric value DS is obtained by scanning the film screen and analyzed by an arithmetic part 2 to calculate the amount (x) of printing exposure and the corrected amount Z of exposure is found from the equation (1), performing printing 3 based upon the corrected amount. Then, individual arithmetic results obtained by analyzing (n) plate of film screens are denoted as xi (i=1-n) and maximum value determined by a visual decision for the individual film are denoted as yi (i=1-n). In this case, coefficients K0 and K1 are calculated from equations (2) and (3). Consequently, the amount of exposure of the determining device for the amount of printing exposure is corrected finely and accurately.

Filed: 1985-02-25
Abstract: PURPOSE:To attain a system having high extension properties by adding a signal control means which validates the data read/write signal given from a sequencer when the unit selection input signal which is turned on and off with operation of an external switch, etc. is kept out. CONSTITUTION:An input/output unit 2 and A/D.D/A units 3 and 4 are connected to a sequencer 1. The unit 2 controls an external load R with the output of a latch circuit 6 via a photocoupler PH2. While for the unit 3 serving as an extension unit, a photocoupler PH5 is turned on and a unit selection signal of 'L' is supplied to a gate G5 as long as external switches SW1 and SW2 are turned on and off respectively. Thus an output of 'L' is produced when the output of an address deciding part 7 is set at 'L'. In this case, the other unit 4 delivers no data to a data bus D since the output of a gate G8 is set at 'H'. Thus the extension units 3 and 4 can be connected to the sequencer 1 with just a single I/O address.

Abstract: PURPOSE:To conduct positive OF alignment by symmetrically arranging guides outside two parallel conveyor belts and projecting a shaft at the approximately center between the belts and a round bar where deviated by approximately half of the OF dimensions of a substrate from the shaft. CONSTITUTION:When the substrate 1 contacts with the shaft 3 by the belts 2, revolution is started in the B direction, and the substrate starts its revolution in the C direction. When the revolution of the substrate advances and an OF1a is positioned where contacting with the revolution stopping round bar 4 separated by approximately half of the OF dimensions from the shaft 3, the revolution of the substrate 1 is stopped in spite of the frictional force of the shaft 3.
