Title: Print producing system
Inventor: UEDA YUTAKA
IPC: G03B27/32
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To provide a print producing system capable of preventing undesired operation to the utmost though operation efficiency is improved. SOLUTION: The number of prints produced from the image data of one frame '1' is previously set. When the number of prints '5' is inputted by a ten key T, the inputted number '5' is set as the number of prints in preference to the previously set number '1'. In the case of instructing the production of the print by using a button without inputting the number of prints by the ten key, a requirement to confirm whether to produce the print by the previously set number '1' is given. Therefore, even when an operator does not input the number of prints through the ten key T, the print which is not intended by the operator is prevented, because the requirement to confirm whether to produce the print by the previously set number '1' is given.
