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.

Image recording apparatus for recording an image on an image recording medium

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.

An image recording apparatus according to this invention includes a frequency dividerfor generating a reference signal of a frequency higher than that of a dot clock signal, a pulse exposure control circuitfor causing a laser beam emitted from a laser diodeto irradiate a recording medium when both an image signal and the reference signal are ON, and a switching devicefor switching between a first recording mode for causing the laser beam emitted from the laser diodeto irradiate the recording medium when the image signal is ON, and a second recording mode for causing the laser beam emitted from the laser diodeto irradiate the recording medium when both the image signal and reference signal are ON.

An image recording apparatus () causes a recording head () to move through a distance corresponding to one half of the recording width of the recording head () in a sub-scanning direction each time a recording drum () makes one rotation. This, light emitting devices () record two line data in advance, and thereafter following light emitting devices () 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 (to) 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.

Apparatus for and method of recording image

Means for detecting scanning positions of first and second recording heads is provided for detecting that the first recording head is opposed to a recording inhibition area (in which an imaging material is not mounted) on a drum, based on an output from the detection means. While the recording head is in the recording inhibition area, correction data for the second recording head is read from a correction data memory and transferred to a submemory in an FPGA for image processing. The second recording head reads the correction data from the submemory. Correction data can be read in parallel.

Image recording apparatus

A control part comprises a division location setting part for setting a division location based on an image data; a scan start position setting part for setting scan start positions of recording heads based on the division location; an image data division part for dividing an image data by the division location; and a head movement control part for controlling movement of the recording heads. The division location setting part sets a division location in a blank area having no pixel to be recorded in the primary scanning direction, in the case of publication printing, in a center margin area between page data. Since the recording heads perform scanning concurrently their respective areas that are divided by the division location, no deterioration in image continuity occurs between the recording heads. This permits an image recorder, though having plural recording heads, capable of performing concurrent recordings without loss of continuity.

An image recording apparatus includes a recording drum rotatable with a printing plate mounted peripherally thereof, a recording head for recording an image on the printing plate mounted on the recording drum, a rotary encoder for detecting a rotation angle of the recording drum, a first and a second sensors for detecting the printing plate mounted on the recording drum, a detection range setting circuit for setting a range of detection of the first and second sensors with respect to the rotation angle of the recording drum according to information on the material of the printing plate, information on reflectance of the printing plate and the presence or absence and the type of positioning holes formed in the printing plate, and a determining circuit for determining a position of an edge of the printing plate mounted on the recording drum, by fetching signals from the first and second sensors based on the rotation angle of the recording drum and the range of detection set by the detection range setting circuit.

In a still picture reproduction system used for presentation of pictures in museums, a particular still picture can be retrieved rapidly by applying a retroactive reproduction function. When the mode is switched from a normal reproduction mode to a retroactive reproduction mode by a mouse, only the first still picture of a series of still pictures reproduced in the normal reproduction mode is reproduced and displayed on an HDTV. These first still pictures in each of a number of series are selectively and manually switched in sequence.

An image recording apparatus comprises a temporary storing magazine for temporarily retaining a recorded photosensitive material sheet. The temporary storing magazine stocks the recorded photosensitive sheet received therein from an image recording section while discharging the recorded photosensitive material sheet into an automatic developing machine. Hence, image recording is executed without interruption and parallel to discharge of the recorded photosensitive material sheet into the developing machine, enhancing the capability of the image recording apparatus.
