る。As shown in FIG. 5, the sensor substrate supporting portion 5b 2 has a substrate end surface supporting projection 5b 23 that abuts on an end face of the sensor substrate 12 opposite to the clip 18, and a sensor substrate lower end that supports the lower end of the sensor substrate 12. A support surface 5b 24 is formed. In addition, the sensor board supporting portion 5 is provided on one side of the clip 18.
on b 2 are retractable adjustable pair of board pressing retaining screw member 21a relative to the clip 18, the board pressing retaining panel 22 having a 21b, integrally formed on the sensor substrate support 5b 2 It is held by the pair of concave grooves 5b 25 and 5b 26 . Then, by adjusting the screw members 21a and 21b to move back and forth with respect to the clip 18, the sensor substrate 12 is supported by the substrate end surface supporting protrusion 5b.
It can be rotated around 23 to change its posture.

ス)も小さくなる。Incidentally, the optical system supporting portion 5b 1 for supporting the illumination light source 8 and the imaging optical system 11 are arranged in the main scanning direction X, the width between the cassette mounting portion 5a 1 and the original 4 in the printing unit support member 5a Since the print head 6 is located in a narrow area, for example, when the print head 6 is located at a position facing the left end portion of the original 4 in FIG. 1 during printing, the left half of the original 4 becomes the left half of the printing portion supporting member 5a. , The part including the sensor substrate supporting member 5b 2 is projected. Further, when the illumination light source 8 is located at a position facing the right end portion of the original 4 when reading the original, only the portion of the print head supporting member 5a on the right side of the illumination light source 8 protrudes from the right end of the original 4. Therefore, in the image scanner printer of this embodiment, the amount of protrusion from the left and right ends of the original 4 is smaller than that of the conventional image scanner printer by the length of the optical system support 5b 1 in the main scanning direction X. The space for accommodating them (dead space) is also reduced.

Further, forming the sensor unit support member 5b, it is also possible to separately form an optical system supporting portion 5b 1 and the sensor substrate support 5b 2. Further, by providing an appropriate optical path changing means such as a reflection mirror between the rod lens array 10 and the light receiving element 14, the mounting position and mounting posture of the sensor substrate 12 on the sensor substrate supporting portion 5b 2 can be changed. It becomes possible to do.

できる。C. Effects of the Invention According to the printing unit and the sensor unit supporting structure for the image scanner printer of the present invention described above, the optical system supporting unit of the sensor unit supporting member is provided between the cassette mounting unit of the printing unit supporting member and the document. Since it is provided, the protrusion amount of the supporting member from the left and right ends of the document can be reduced by the length of the optical system supporting portion in the main scanning direction as compared with the conventional one. Therefore, the space for accommodating them (dead space) is reduced, and the size of the apparatus in the main scanning direction can be reduced.
