Abstract

PURPOSE:To simplify the constitution and the picture processing by recording both long side main scanning picture information and short side main scanning picture information while using major parts of the device such as a drum, a drive mechanism and a controller in common. CONSTITUTION:Picture information recorded by a recording head section 8 is stored in a 1st or a 2nd buffer memory 2 or 4 with selection and two ways of control are applied to a main scanning drive mechanism 7 and a subscanning drive mechanism 9 depending on the short side main scanning and the long side main scanning in the selected picture information. Thus, the major components of the device such as a drum, a drive mechanism and a controller are used in common for the recording of the long side main scanning picture information and the short side main scanning picture information. Thus, the constitution and the picture processing are simplified.

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an image output device for recording, for example, image information on a newspaper page onto a film or sheet-like sensitive material.

BACKGROUND ART Conventional devices of this type include those that record paper image information transmitted by facsimile onto photosensitive material on a drum in a predetermined format, and CTS (computerized typesetting system).
There are two types of devices that record paper image information created by a computer on a photosensitive material on a drum in a prescribed format, and these two types of devices are used depending on the input source of the image information. was.

However, with this configuration, there is a problem in that two types of devices must be prepared and used separately for inputting and filtering image information.

The above problem arises for the following reasons.

In other words, for example, when recording image information on a newspaper page,
Image information transmitted by facsimile and image information created by a computer have different size ratios (aspect ratios) in the main scanning direction and the sub-scanning direction, and are not compatible. The image information of the newspaper page transmitted by facsimile is long side main scanning image information, and the long side of the image is in the main scanning direction. On the other hand, the image information of a newspaper page created by a computer is short-side main-scanning image information, and the short side of the image is in the main-scanning direction. Therefore, the newspaper image output device has
There were two types: one for facsimiles, which was configured to accommodate long-side main-scanning image information, and one for computers, which was configured to accommodate short-side main-scanning image information. Since these two types of devices are not compatible, it is necessary to install two separate devices for inputting and filtering the image information in the place where the above two types of image information are received and recorded.

The present invention has been made in view of the above-mentioned problems, and it is possible to quickly and easily process long-side image information and short-side image information with a single device without greatly deteriorating the configuration or performing particularly complicated image processing.

A configuration in which the main scanning drive mechanism and the sub-scanning drive mechanism are controlled in two ways depending on whether the selected image information is short-side main scanning or long-side main scanning.
