The camera assembly 100 of present embodiment has lens barrel member 10, inserts first lens 20, aperture plate 30, second lens 40, light filter 70 and dividing plate 50 in this lens barrel member 10 in turn, also possesses the substrate 60 that is equipped with imaging apparatus 61.The substrate 60 that is equipped with imaging apparatus 61 is members of supplying with as selling product on the market, combines with lens barrel member 10 at last.Key element beyond the imaging apparatus 61 is made of the formed products of synthetic resin material.Fig. 1 illustrates the above-mentioned key element of combination and the assembling completion status of carrying out combination, in the following description, for convenience, with top, the top of Fig. 1 as each key element, with the optical axis direction of camera assembly 100 as directions X, will with the direction of light shaft positive cross as the Y direction.
Each key element is described.Lens barrel member 10 is reversed and monomer whose shape shown in Figure 2 up and down, as shown in Figure 2, lens barrel member 10 has the underframe portion 11 of rectangle of below and cylindric 12 of the top little than these rectangle underframe portion 11 diameters, and cylindric 12 upper end is sealed by having the upper end board 14 that light beam is taken into hole 13.Rectangle underframe portion 11 with cylindric 12 between be connected by light shaft positive cross wall (shading wall) 15.Because the inside diameter D 1 of cylindric 12 inner cylinder face (optical axis center fitting portion) 12A constitutes the position reference of the light shaft positive cross Y direction of first lens 20 and second lens 40, therefore is shaped with high precision.At the inside surface of upper end board 14, be formed with the optical axis directions X reference field 14A of ring-type at its circumference.Below, " optical axis directions X reference field " means the reference field with optical axis X quadrature.
First lens 20 are reversed and monomer whose shape shown in Figure 3 up and down, as shown in Figure 3, first lens 20 have the ring-shaped flat board 22 of the periphery of the positive concave-convex lens of protruding positive concave-convex lens portion 21 and this portion 21 at the upside (light beam is taken into hole 13 sides) of central part, below this ring-shaped flat board 22, be formed with the benchmark projection (foot) 23 of a plurality of (in illustrated example) arcuation of optical axis center to be separated with three between equal angles.Benchmark projection 23 is arranged on the imaginary circles in the outside of effective diameter portion (positive concave-convex lens portion 21) of first lens 20.Ring-shaped flat board 22 has with respect to the inner cylinder face 12A of lens barrel member 10 with the chimeric external diameter of big clearance (in Fig. 1 with this clearance exaggeration expression).That is, the telescoping part of ring-shaped flat board 22 and inner cylinder face 12A does not influence the positional precision of the light shaft positive cross Y direction of first lens 20.Discontinuous inner cylinder face (optical axis center fitting portion) 23A that will be formed by the benchmark projection 23 of a plurality of arcuations on the other hand, is configured as the diameter D2 with high dimensional accuracy.Around the upper surface of ring-shaped flat board 22, be formed with optical axis directions X reference field 22A with the optical axis directions X reference field 14A butt of upper end board 14, the inboard of the benchmark projection 23 of the lower surface of ring-shaped flat board 22 constitutes the diaphragm gap formation face 22B with light shaft positive cross, and the lower surface of benchmark projection 23 constitutes optical axis directions X reference field 23B.
Second lens 40 as with its reverse up and down shown in Figure 4, have at the upside (first lens, 20 sides) of central part the periphery of protruding positive concave-convex lens portion 41, this positive concave-convex lens portion 41 chimeric outer cylindrical portion 42, also lean on the position of periphery to determine annulus 43 than this chimeric outer cylindrical portion 42.Because chimeric outer cylindrical portion (optical axis center fitting portion) 42 is entrenched in the chimeric precision of height in the inner cylinder face 23A of benchmark projection 23 of first lens 20, therefore can produce the positional precision (first lens 20 with the optical axis of second lens 40 just in time consistent) of second lens 40 with respect to the light shaft positive cross Y direction of first lens 20 by this optical axis center telescoping part.In addition, out cylinder face (optical axis center fitting portion) 43A that annulus 43 is determined in the position is chimeric with high dimensional accuracy and cylindric 's 12 inner cylinder face 12A, has determined the position of second lens 40 with respect to cylindric 12 light shaft positive cross Y direction of lens barrel member 10.That is, determine that by inner cylinder face 12A and position the engomphosis relation of annulus 43 (out cylinder face 43A) and benchmark projection 23 (inner cylinder face 23A) and the engomphosis relation of chimeric outer cylindrical portion 42 determine the position of light shaft positive cross Y direction with cylindric 12 of the lens barrel member 10 first chimeric lens 20 and second lens 40.
Determine that in the position upper surface of annulus 43 is formed with the optical axis directions X reference field 43B of ring-type.The optical axis directions X reference field 23B butt of the benchmark projection 23 of this optical axis directions X reference field 43B and first lens 20, thereby the position of the optical axis directions X of definite first lens 20 and second lens 40.
In addition, determine that in the position lower surface of annulus 43 is formed with the benchmark projection (foot) 44 of a plurality of (in illustrated example, to be separated with three between equal angles) arcuation of optical axis center, the lower surface of this benchmark projection 44 constitutes optical axis directions X reference field 44A.
The diaphragm gap that is formed with ring-type at the upper surface of the chimeric outer cylindrical portion 42 of second lens 40 forms face 42A, form in this diaphragm gap between the diaphragm gap formation face 22B of face 42A and first lens 20, be formed with diaphragm under the state of the optical axis directions X reference field 43B butt of determining annulus 43 in the optical axis directions X reference field 23B and the position of benchmark projection 23 and take in gap (space) P (Fig. 1).The thickness setting of the aperture plate 30 that is formed by light screening material is that to take in gap P than this diaphragm thin, and the external diameter of aperture plate 30 forms slightly littler than the diameter D2 of the inner cylinder face 23A that is formed by a plurality of benchmark projections 23.Therefore, aperture plate 30 is supported with quick condition (not being compressed) between first lens 20 and second lens 40, by the central opening 31 of aperture plate 30, can subtend first lens 20 and harmful light beam of the outside incident of the effective diameter of second lens 40 carry out shading.
