A plate body 2, multiple hologram layers 3 are provided in the thickness direction of the plate body 2, and at least one of the multiple hologram layers 3 is formed of spirally continuous hologram bands 4. Erasure areas 4A and 4B and non-erasure areas 4C and 4D of the hologram band 4 are provided in the length direction of the hologram band 4. Non-erasure areas 4E and 4F of the hologram band 4 are formed on both sides in the direction orthogonal to the length direction of the hologram band 4 in the erasure areas 4A and 4B.

An electronic device that performs at least reading or regeneration of data in or from a hologram disc is characterized by including an objective lens 11 disposed opposite a hologram disc (MH) 1; a laser light source 5 that emits a beam toward the objective lens 11; and a light receiving element 17 that receives a beam reflected from the hologram disc (MH) 1 by way of the objective lens 11, wherein a corner cube array 8 that reflects a portion of a beam traveling from the laser light source 5 toward the objective lens 11 is interposed between the laser light source 5 and the objective lens 11.

An inkjet recording apparatus includes an absorber configured to abut a nozzle surface of a line head to absorb ink adhered on the nozzle surface. A portion of the absorber which corresponds to an opening of a nozzle is removed. The absorber is configured to abut the nozzle surface except for a portion near the nozzle. Ink remaining on the nozzle surface is absorbed by the absorber. Thus, when the nozzle surface is wiped with a blade, accumulation of a large amount of remaining ink is prevented.

A printer includes: a recording section for recording information on a recording medium; a medium carrying mechanism for carrying the recording medium on which information has been recorded by the recording section; a medium accommodating section extending in a vertical direction or in a slanted vertical direction for accommodating the recording medium carried by the medium carrying mechanism; and pusher means for pushing the recording medium carried by the medium carrying mechanism into the medium accommodating section.

An ink-jet cartridge for ink-jet printers includes a nozzle-cleaning mechanism built in the cartridge itself for removing residual ink and foreign matter, such as dust and dirt including paper powder, from nozzles. Since the built-in nozzle-cleaning mechanism is replaced automatically when the cartridge is replaced, and since the replacement of the cartridge generally takes place before the nozzle-cleaning mechanism deteriorates mainly due to contamination with ink, the nozzles are always kept clean and a reliable printing operation with high quality printing is insured throughout the service life of the cartridge.
摘要:
An improved ink-jet printer of the so-called current flow type wherein a current is passed through a conductive ink contained between a pair of electrodes so as to cause the ink to become vaporized and cause trapped gasses or bubbles to expand suddenly, exerting a sufficient pressure upon the ink to force a droplet of ink from a nozzle is disclosed, wherein at least one projection of electrically insulating material is disposed between the pair of electrode for increasing the density of the current at a position directly below a nozzle. With the projection thus provided, only a limited portion of the conductive ink participates in the generation of heat, and boiling of the conductive ink takes place only at the position directly below the nozzle. Accordingly, droplets of conductive ink are produced with minimum power consumption and can be ejected in a uniform direction. The position where boiling of the conductive ink takes place is remote from the electrodes, so that the electrodes are substantially free from cavitation and thermal shock and, hence, they have a long life span.

A recording apparatus includes a first light source irradiating first laser light, a second light source irradiating second laser light, an optical spatial modulating unit applying information to the first laser light, and an objective lens collecting the first laser light and the second laser light at different positions on the same optical axis. A hologram recording operation uses a first optical path and a second optical path. The information light is conducted to the objective lens along the first optical path. The reference light is conducted to the objective lens along the second optical path. At the same time, an address/servo control operation is carried out by employing a third optical path along which the second laser light is conducted to the objective lens. The DVD recording operation uses the second optical path. The CD recording operation uses the third optical path.

A holographic recording apparatus causes reference light and information light to interfere with each other, and records the interference pattern in a recording medium. The holographic recording apparatus has an objective lens and a focus position controller. The objective lens focuses both the reference light and the information light at a focus position of the recording medium. The focus position controller changes the focus position into a predetermined position on the light path of the reference light.
