It has come to be regulated by the following. A bent portion 5c is provided at the lower edge of the side plate 5a of the element support plate 5, and the tip of the focus adjustment screw 21 is in contact with the lower surface of this bent portion 5c. Therefore, by adjusting the screw 21, the element support plate 5 can be rotated around the fixed shaft 14Tk.
Along with this, the fulcrum of the element substrate 4 moves up and down, and the element substrate 4
tries to rotate relative to each other, but as the element support plate 50 rotates, the pin 19a of the intermediary lever 19
Side plate 5! It is moved up and down by L and rotated about the shaft 18, and a position near the free edge of the element substrate 4 is moved up and down by another pin 19b of the intermediary lever 19. Here, the conditions such as the position of the shaft 18 of the intermediate lever 19 and the rotation radius of the two bins 19a and 19b are as follows.
The element substrate 4 is set to move vertically in parallel when the element support plate 50 rotates about the fixed shaft 14. Therefore, by adjusting the screw 21, the element substrate 4 and the light-receiving element 3 integrated therewith are moved. It is designed to move vertically in parallel while maintaining a constant attitude with respect to the incident optical axis.
