Abstract: The present invention relates to an ID information forming apparatus for making ID information to prepare an ID card. The apparatus comprises: an image taking section to take a facial image of a person, and to make a first facial image data corresponding to the facial image of the person; an image information forming section to make first image information from the first facial image data; an information acquiring section to acquire second image information regarding a second facial image data corresponding to a past facial image of the person; a checking section to check the first image information against the second image information; an eye-opening degree judging section to judge a degree of eye-opening of the first facial image data; and an ID information forming section to form the ID information based on results of checking by the checking section and of judging by the eye-opening degree judging section.

Abstract: There is described an image-recording medium and an image-reading method, which make it possible to improve reading accuracy of information by avoiding duplication of an optical variable image with the information. The image-recording medium includes a substrate, an image-receiving layer provided on the substrate and an optical variable layer provided on the substrate, wherein at least a part of the optical variable layer includes an optical variable image, and the optical variable image is formed in a manner such that the optical variable image, overlapping with an image recorded on the image-receiving layer, emerges in a first direction, while the optical variable image, overlapping with an image recorded on the image-receiving layer, does not emerge in a second direction.

Abstract: A photographic image-bearing recording member and a manufacturing method of it are disclosed. The recording member comprisesa support,a thermoplastic resin layer bearing a photographic image, which is provided on a surface of said support, anda protective layer comprising a radiation setting composition and being set with irradation of an actinic radiation, which is provided at a outermost position of the side of the support on which said thermoplastic layer is provided. Symbols or characters may be further beared in the thermoplastic layer. The symbols and characters are preferably formed on the themopastic layer by the heat-transfer printing method.

Abstract: An image recording apparatus wherein a plurality of laser beams are scanned on a color photosensitive material by an optical deflecting device, the laser beams are detected by beam detecting devices, and record starting timings for the laser beams are controlled on the basis of detection signals provided by the detecting devices so that respective record positions of the laser beams are the same.

Abstract: An ink jet printing device including a printing head having a nozzle through which ink can be ejected. The head includes an internal chamber ink and ink ejection is caused by internal pressure pulses. The internal chamber is formed in part by a deformable diaphragm which prevents extreme ambient temperature variations from causing damaging liquid pressure fluctuations.

Abstract: An ink jet printer wherein a mechanical vibration is applied by an electromechanical transducer secured to a printing head to the ink in a nozzle and a pressure chamber of the printing head when the ink jet printer is not in a printing operation state, so that an ink flow is formed in the ink passage within the period of time including the mechanical vibrating operation or after the completion of the mechanical vibrating operation. The electromechanical transducer is used when droplets are jetted out. An electromechanical transducer which is brought into contact with the printing head only when the mechanical vibration is generated can be employed. The nozzle can be covered with a liquid within the period of time including the whole of the mechanical vibrating operation.

Abstract: A printing head for an impulse jet type ink-jet printing apparatus which includes a plurality of nozzles supplied with ink from a common ink chamber through ink flow channels and pressure chambers which are substantially perpendicular to the nozzles. Piezoelectric-crystal elements are disposed in each pressure chamber and have a length to width ratio not less than 2 to 1 and not greater than 20 to 1.
