Note that the output of the semiconductor laser f1 is changed to f! by a pulse corresponding to the image signal. , 'J 1itIj.

(Problems to be Solved by the Invention) Considering the shape of the light beam on the scanning plane, it is not possible to increase the number of resolution points. For this reason, either the output width is limited, or the output width is given priority at the expense of resolution.

In addition, by arranging multiple optical integrated devices in parallel,
It is possible to increase the output width.

In this case, very precise adjustment is required, although it depends on the resolution. Alternatively, it is necessary to arrange the overlapped portions of the output lights of a plurality of optical integrated devices so that one side is not printed.

The present invention has been made in view of the above-mentioned problems, and its object is to provide an optically integrated printing device capable of producing continuous print output using a plurality of optically integrated elements. It is about realization.

(Means for Solving the Problems) The present invention, which solves the above problems, is an optical integrated printing device that prints by irradiating a light beam onto a photosensitive material. It is characterized by having a light integrated element and a print adjusting means provided on at least one of two adjacent light collecting elements so that the print formed on the photosensitive material is continuous.

(The polarized light beams from the plurality of optical integrated elements are focused on the photosensitive material.Then, the print adjustment means causes continuous printing by the light beams from the adjacent optical S! elements.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is an enlarged view of the optical integrated device 10.

The width of the condensing grating coupler 15 of the optical integrated device is E,
The distance from one end of the condensing grating coupler 15 to the end of the optical integrated element 10 is d I , and the condensing grating coupler 15
From the other end to the end of the optical integrated device 10, the focal point of the d2.0-order light is ○, the optical scanning width is PQ, then 0P=(1, PQ-F, then F+dl +d2 ≦7+L... ■F1d+
10d2 > 7 +L...It can be divided into two cases as shown in ■■.

First, an example in which the above equation 0 is satisfied will be described with reference to FIG. If this formula 0 holds true, the printing width can be increased by arranging a plurality of optical integrated devices on the same plane.

The light emitted from the semiconductor laser 11 passes through the waveguide lens 1.
After passing through the 5AWI transducers 13 and 14, the light is focused on the printing surface 30 by the condensing grating coupler 15.The signal applied to the SAW + transducer 13 is continuously changed. By changing the focus position on the printing surface 30, the focus position changes continuously (P
+ to Ql). The number of scanning points is determined based on the shape of the beam, and can be resolved from several hundred to one. , S.A.W.
Lancer 14 is 5AWI-Lance 7″1-
This is a means for changing the scanning position by the optical system 13.

The optical integrated device 20 also operates in a similar manner.

In this configuration, the zero-order light from the integrated optical element 10 and the light emitted from the integrated optical element 20 interfere with each other. Therefore, a light shielding plate 31 is provided to prevent the zero-order light from the optical integrated device 10 from reaching the printing surface. Further, the SAW transdules are arranged so that the scanning start point P1 of the light emitted from the optical integrated device 10 and the scanning end point Q2 of the emitted light from the optical integrated device 20 are continuous.
It is necessary to apply an appropriate signal to 24 to move the scanning width of the light emitted from the optical integrated device 20.

As described above, wide printing can be performed using two optical integrated elements. Furthermore, when three or more optical integrated devices are arranged side by side, they are arranged in the same way, and the light shielding plate and the scanning width of the emitted light are adjusted.

Next, an embodiment in which the above equation 0 (F+d, 10+12>/+L) is established will be described with reference to FIG. 3 and subsequent figures. If this equation 0 holds true, it is not possible to arrange a plurality of optical integrated devices on the same plane. Therefore, by arranging the optical integrated elements in an offset manner, the printing width can be increased.

FIG. 3 is a configuration diagram showing an example of a configuration in which a plurality of optical integrated devices are arranged in an offset manner. As long as the printing positions of the respective optical integrated elements are arranged consecutively, the positions of the optical integrated elements may be in any position. Figure 4 is this 4

Figure 5 shows the above equation 0 (F + d + + d 2 >
l! +L) is a configuration diagram showing a schematic configuration of another embodiment. In this figure, three optical integrated elements 10°20.40 are offset and arranged in a staggered configuration, and the printing positions are shifted in the sub-scanning direction (the direction of movement of sensor xi). Here, by shifting the timing of the image arc (print signal) given to each optical integrated element, the thermal
9, printing is continuous and wide printing can be performed.

FIG. 6 is a configuration diagram showing a configuration in which two sets of optical integrated devices are arranged on one substrate. Components in this figure that are the same as those in FIG. 1 are designated by the same numbers and their explanations will be omitted. The difference from FIG. 1 is that the 5AWt-lancer 41 scans both the light from the semiconductor laser 11 and the light from the semiconductor laser 1121. Therefore, the scanning directions are reversed. Further, by applying an appropriate signal to the SAW)-lance γ user 24, the position of print 2 is moved so that print 1 and print 2 are continuous.

As described above, it becomes possible to obtain continuous print output using a plurality of integrated optical elements.

(Effects of the Invention) As described above in detail, the present invention is configured so that printing by light beams from adjacent optical integrated elements is continuous by adjusting the printing position. As a result, it is possible to realize an optically integrated printing device that can obtain continuous printing output using a plurality of optically integrated elements.
