摘要： An image recording apparatus (1) causes a recording head (20) to move through a distance corresponding to one half of the recording width of the recording head (20) in a sub-scanning direction each time a recording drum (10) makes one rotation. This, light emitting devices (23, 24) record two line data in advance, and thereafter following light emitting devices (21, 22) record the same line data repeatedly at the same position. This increases the energy of laser light beams given to a recording position on a printing plate (P) to accomplish the recording of an image with reliability. The recording speed is not extremely decreased because not all light emitting devices (21 to 24) are used to make the repeated recordings at the same position on the printing plate (P). Further, the construction of optical systems and driving systems in the image recording apparatus is not complicated.

摘要： When rotating a recording drum at low speed, air is jetted from air jet ports toward a point of irradiation, in a direction to diffuse a gas generating from an image recording medium upstream with respect to a direction of rotation of a recording drum. An air curtain approximately semicircular about the point of irradiation is formed upstream thereof with respect to the direction of rotation of the recording drum. As a result, the gas can hardly diffuse from the point of irradiation upstream with respect to the direction of rotation of the recording drum. The gas is collected from a gas suction opening. Thus, the gas is reliably prevented from contacting the image recording medium having an image recorded thereon.

摘要： A laser light source has a plurality of semiconductor lasers arranged in a direction intersecting a primary scanning direction X. The semiconductor lasers are arranged in such a positional relationship that each semiconductor laser is located upstream, in the primary scanning direction X, of a different semiconductor laser located adjacent thereto and downstream thereof in a direction in which air is blown from an air blowoff pipe.

摘要： 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 contaminating the back surface of the image recording medium.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 31 do not occur downstream in a gas moving direction.

摘要： Positioning of a printing plate in an image recorder is performed by the same method used for punching positioning holes for printing press in the printing plate. Specifically, the positioning for image recording is performed with reference to an edge of the printing plate on the same side as the edge of the printing plate used as a reference for punching the positioning holes for printing press. When the positioning for punching the positioning holes for printing press is performed with reference to the central position of the printing plate, the central position of the printing plate is detected based on a measured width of the printing plate, and the positioning for image recording is carried out with reference to the central position. Consequently, an image recorded on the printing plate by the image recorder and the positioning holes for printing press in the printing plate always have the same positional relationship.
