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.

Image recording apparatus with gas blowing device

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.

Image recording apparatus having a laser source

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

In a separator for separating a stripping sheet from a composite film formed by a base sheet and the stripping sheet which are superposed with each other, the composite film is first so carried and arranged that its forward end portion extends over a separating clearance formed in a support, and then a blade is pushed into the separating clearance for thrusting the composite film into the separating clearance in a bent state. Thus, the forward end portion of the composite film is separated (i.e., delaminated). Thereafter the base sheet and the stripping sheet are independently sucked/held on the delaminated forward end portion, and the stripping sheet is completely separated from the base sheet while widening the space between the held positions of these sheets. Due to the aforementioned structure and operation, the composite film can be separated in a simple structure with minimum force, and the separator can be reduced in size and power.

Sheet separator for image recording process

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.

Apparatus for and of recording an image using a photosensitive drum for

In a printing apparatus, a supply pallet storing an original and a photosensitive film is located above a printer. The films are carried onto a transparent plate of the printer in this order by a carrier. Then, light from a light source of the printer is directed toward the transparent plate, whereby an image provided on the original film is printed onto the photosensitive film. Thus, the printing apparatus is small in plane size.
