Also,
- the left and right display sections 15a and 15b do not change the spacing even when the left and right bins are adjusted by rotating the levers 43. Due to slight dimensional differences during manufacturing and assembly errors, the display units 15a and 15b may be out of focus (unbalanced) on the left and right. At the time of assembly, it is necessary to finely adjust the distance between the left and right bases 17a and 17b and the lens units 18a and 1Bb to eliminate the left and right bin balance.
- bosses 53a and 53b with knurls are fixed to the ends of the left and right universal joints 44a and 44b. Insert the bosses 5 3a and 5 3b into the knurled holes 4 3a provided on the left and right inner sides, and connect them. ⁇ At this time, the left boss 5 3a or the right boss 5 If one of 3b is slightly rotated back and forth and fitted into lever 43, the left and right universal vertices 3 4a and 4b are displaced around the axis of lever 43.
- the universal joints 44a and 44b can be attached to the lever 43 at different phases.
- the lever 43 is in the neutral position, but the distance between the left lens unit 18a and the substrate 17a is slightly larger than the distance between the right lens unit 18b and the substrate 17b.
- the variation of the left and right bint is eliminated. That is, when the universal joints 44a and 44b are assembled, the balance of the left and right bint can be adjusted very easily. Therefore, the dimensional tolerance of each part including the lens can be increased, which can contribute to cost reduction.
