摘要:
An image forming apparatus can form an image of a high-precision security information for anti-reproduction. A photosensitive material-coated area in a recording paper is exposed with an exposure unit to form an image of a high-precision security information. Since the image of the security information is thus formed by exposing the photosensitive material, it can be formed as an image incapable of reproduction.

A card printer in a card information management system. The card printer has a data input part for inputting data acquired by a user. The data is character information of a character generated by a program stored in a predetermined apparatus according to predetermined operations of a user. The card printer has a user ID input part for inputting an ID of the user. The data inputted from the data input part is converted into print information by a print information generation part. Approval information of the supplier of the card is generated by an approval information generation part. This print information and the approval information are printed on a card by a print part through an image processing part and a print control part. The user can obtain the card to which the approval information is added on demand.

摘要:
A secrecy management information recording device has an information input section which inputs image information printed by a printer and secrecy management information corresponding to the image information, a transport mechanism which receives a printing sheet on which the image information has been printed by the printer, and discharges the sheet after passage over a heat generating resistor, and a magnetic tag forming section which controls generation of heat by the heat generating resistor according to content of the secrecy management information corresponding to the image information printed on the transported printing sheet to thermally transfer at least one magnetic member contained in a thermal transfer sheet onto the printing sheet. A magnetic tag representing the content of the secrecy management information is thereby formed on the printing sheet. This device records additional information corresponding to image information on a printing medium at the time of copying of the image information to the printing medium in such a manner that the additional information is remotely readable.
摘要:
An apparatus for correcting positional deviation of the light source emitting light beams in an image recording apparatus is disclosed which corrects change of the image size (dimensions of the image) on the photosensitive member due to positional deviations of beam spots on the photosensitive member on account of physical distortions caused by external vibration, temperature change, and the like. Changes in the diameter of detective light beams are measured by photodetecting portions 5.sub.R and 5.sub.L and piezoelectric devices 6a and 6b are driven based on the results of the detection, whereby the semiconductor laser array 1 is moved so that the multiplication b/a for the image size may be kept constant.
