Abstract

PURPOSE:To attain a picture reading/recording device with a simple constitution, without producing any step difference of recording density at the boundary of adjacent reading regions, even at the reading and recording of multi-gradation, by using a light source forming an equal illuminance band over longitudinal and lateral width of a plane of an original to be read, and a reading/recording section combining integrally heads recording image on a recording medium. CONSTITUTION:When a center of the reading/recording section 20 is moved from a point A1 to a point B1, the picture information of an original plane S1 shown in broken lines for the boundary section is read and recorded, and then when the center of the reading/recording section 20 is moved from a point B2 to a point A<2>, the picture information of the original plane S2 is read and recorded, the reading/recording of original planes S3, S4 is attained similarly. Since the light source 3 is scanned reciprocatingly in longitudinal direction of the plane S of original to be read while forming the equal illuminance band over the entire lateral width of the plane S of original to be read, the uneven illuminance of the boundary section of the reading original planes S1, S2, S3, S4 to be split is eliminated and the recording without density difference is attained even if multi- gradation of reading/recording is performed.

Look - when the direction of travel is reversed, the isoluminous zone! , j1 direction, that is, in the lateral direction of the document 1, one reading/recording unit (go) is moved by the width of the cropped image. Therefore, the W recording section 2 (center part #-1 of +) is moved in the direction from point A1 shown in FIG. It is moved by a distance corresponding to the recording width, and furthermore, when it reaches point B2, it is moved in the opposite direction to the direction in which it was first moved and scanned, that is, points 8225 & d, The movement scan f is completed in the direction toward A2, and these movement scans are repeated sequentially to obtain a reading record 1+lt 20
When the center reaches point A4, it is stopped or returned to point A+, where it was first positioned. When the center of the reading/recording section moves from point A to point B1, image information on the document surface 8 whose boundary is indicated by the & mark is read and recorded, and then the reading/recording section moves from point A to point B1. When the center of the side moves from point B2 to point A2, the document surface S
A recording of the image information of step 2 is performed, and thereafter, reading and recording of the document surface date 89, step 4, is performed in the same manner. In this way, #'j%? Complete reading and recording of all image information on the additional manuscript page date. In this case, the light source 3 is scanned back and forth in the vertical direction of the document surface 8 to be sampled while forming an equiluminous band over the entire width of the document surface B in the horizontal direction. The illuminance unevenness at the boundary between the divided and clear original surface sl and 82e SB + 84 is smoothed out, and it is possible to record without temperature difference even in the case of reading and recording in multiple gradations. The driving device 3 (1 is the light source 3 and the bladder recorder 30
The Aν original area to be read is reciprocated in the vertical direction, and when the scanning direction is reversed, only the reading/recording unit 4) is moved and scanned in the transverse force direction by the recording width of the original area S6 to be read. If the conventional bladder J scans the reading section and the recording section separately at 11^IK,
Compared to the IP' recording device r, the configuration of the moving device 30 is greatly simplified. Incidentally, the above-mentioned isoluminous zone is sufficient as long as the illuminance in the pitching direction is uniform, and the illuminance in the 4t/i direction is not necessarily uniform. Other real h1 of reading and recording device
FIG. 4 is a cross-sectional view showing the structure of the eleventh example, and FIG. Here, the imaging optical system is mainly composed of a 111-type mirror 11 whose reflective surfaces intersect with each other and a Dano mirror array 13 in which a plurality of lenses are arranged in a straight line. Medium, 1/ns γ Ray 12 Muyo Dano ;Ra I3
Furthermore, an amorphous semiconductor γ[/i] 5 as a photoelectric sensor array is arranged at the image point of this imaging optical system, and furthermore, this amorphous semiconductor array 15 and a thermal head 16 are integrated. They are integrally coupled together and are also integrally coupled to a coupling optical system via a case 17. By adopting such a structure, it is suitable for Mff records/
If a linear, same-magnification image can be easily formed, the M-increasing recording section can be made extremely compact. In addition, in the above-mentioned example, a light source 3 with a continuous light emission distribution, such as a logen lamp or a fluorescent lamp, was used as the 0-inch light source 3. J
: Even if a large number of light emitting diode arrays 38f are arranged between the cleaning recording section Δ)a and the document support glass 2, a band-like layer will not be formed on the surface of the document to be collected. It is of course possible to obtain an equiq(9) plane, which allows a smaller 'P-Nd9 recording device of 85 mm. In addition, in the above embodiment, an isoluminance surface was formed by extending over all 11 horizontal directions of the surface of the original document to be read (F′i), but the light source was longer by 1 than the horizontal width of the surface of the document to be increased by ytt. If 1 forest is formed, even if this cover forms a uniform J'!?! deformed surface over the entire vertical width of the manuscript surface, the above-mentioned ftfl root knot! cane is Is. In the actual gun example above, a thermal head was used as the recording head, but in order to overcome the →l''-mal head, an inkjet type recording head was combined with the Goo Mirror l/ns 1 etc. to create a 7υ. Of course, it is also possible to integrate the father part and the recording part. #2 More than the effects As is clear from the tvFIi, the image reading and recording device IIζJ of the present invention: Even when performing 4-channel recording, there may be a difference in recording density in the 5-field area of the reading area that is 1 m apart), but it can be avoided by integrally closing the reading area, the reading area, and the recording area. The configuration is greatly simplified, and a compact and inexpensive device can be provided.
