Title: Cipher matching device
Inventor: ARIMORI FUKUO
IPC: G09C1/00
Filed: 1990-02-02
Abstract: PURPOSE:To prevent a card where a cipher such as a password is stored from being used illegally by prompting an operator to input a cipher of the king corresponding to one kind of cipher selected indefinitely among read cipher and judging whether or not the input cipher matches the read password. CONSTITUTION:When the selected cipher is a cipher A, 'Input the cipher A' is displayed on a display device 5. Mutually different ciphers are stored for ciphers A, B, and C, and the user inputs the password corresponding to the cipher A through a cipher input device 6. When the ciphers match each other, the cipher matching device 3 outputs a cipher coincidence signal and when not, the operation ends. Thus, the cipher matching device 3 prompts the user to input a new cipher every time the inputted cipher matches the selected cipher and when all ciphers are coincident, it is judged that the user is proper, thereby increasing the effect to prevention against illegal use. Consequently, ciphers are prevented from being used in the same pattern at every time and it becomes difficult to use the card illegally.

IPC: G03F7/07
Filed: 1994-02-21
Abstract: PURPOSE:To prevent defect in plate making by a dip developing method, to enable quick processing, to always supply a new processing solution efficiently, and to enable processing with a small quantity of waste processing solution so as to eliminate complicatedness in maintenance by supplying a developing solution to a developing solution applying part corresponding to the width of a plate so as to develop a photosensitive material. CONSTITUTION:A photosensitive material P is inserted from an inlet guide 7, and the cross- direction positional information is obtained from the material by a width detecting sensor 8 to control a driving motor 9. A processing liquid drop nozzle 4 is repeatedly moved between both ends in the cross direction of the photosensitive material P to supply the processing liquid, and the liquid is applied to the material by bar-like members 1. Though the nozzle is repeatedly moved between both ends in the cross direction of the photosensitive material P, the liquid staying in a gap between a pair of bar-like members 1 is about to spread regardless of any influence on the surface tension of the processing liquid, so that it is indifferent to shifting a little inside from the both end positions in the cross direction. Thus, the consumption amount can be reduced by applying the quantity of a processing liquid according to the plate size and always supplying a new processing liquid to the plate to prevent deterioration, so that the processing liquid is prevented from being spread to the unnecessary back of the plate.
