With Record Receiver In An Evacuated Enclosure Patents (Class 347/227)
  • Patent number: 8194110
    Abstract: In an image recording apparatus using an image recording medium which generates a gas when irradiated with a light beam, the gas and the like are prevented from drifting into a space between the image recording medium and a drum, and thus contamination of the back surface of the image recording medium is prevented. The gas is effectively prevented from drifting to the back surface of a plate P by setting a relative positional relationship of an extending direction of each suction groove L, an attaching position of the plate P, and an air blowing direction so that unclosed regions, not closed by the plate P, of suction grooves L formed in a drum surface do not occur downstream in a gas moving direction.

  • Patent number: 7533981
    Abstract: An image-forming apparatus and print media recognition method therefor, wherein the apparatus comprises a first light-emitting element for emitting light to a print medium at a predetermined first incident angle, a second light-emitting element for emitting light to the print medium at a predetermined second incident angle, and a light-receiving element installed along an optical axis of total reflection light emitted from the first light-emitting element and reflected from a surface of the print medium. The apparatus further comprises a control unit for controlling the first and second light-emitting elements to alternately emit light for deciding a print medium material based on a reflection amount of light received by the light-receiving element and establishing print conditions adapted to the print media.

  • Patent number: 7230636
    Abstract: A gas is generated from a printing plate by exposure of the printing plate. A gas diffusing suction unit jets air from air jet ports to diffuse the gas generated from the printing plate by irradiation of laser light. The gas diffused by the air is sucked along with the air from a gas suction opening of the gas diffusing suction unit. At this time, a gas suction velocity is set to 1.2 or more times an air jet velocity to suck the gas/air efficiently. The gas/air may be sucked efficiently by setting a volume of suction to 30 or more times a volume of air jet.

  • Patent number: 7209157
    Abstract: A plate fixed to a recording drum is irradiated with a laser beam emitted from an objective lens of a recording head, to generate gas. The recording head has a gas diffusion/suction unit forming an air stream in front of the objective lens. Further, a second suction unit elongated along the rotational axis of the recording drum is arranged between a transport unit supplying the plate to the recording drum and the recording head. Thus, it is possible to prevent the gas not only from contaminating the objective lens but also from diffusing in a housing following rotation of the recording drum. Consequently, an image recorder employing a photosensitive material generating gas in reaction to heat resulting from the laser beam emitted from the recording head can minimize contamination of the recording head, the transport unit etc. arranged in the housing of the apparatus with the gas.
