Embodiment approach 1
[0035] The drawings used in the following description are schematic diagrams. Dimensional ratios and the like in the drawings do not necessarily correspond to actual ones.
[0036] [Structure of camera unit]
[0037] Such as figure 1 As shown, the camera module 1 includes a lens unit 2 and a holding member 3 . The lens unit 2 has a lens 21 . The lens 21 is fixed to the lens unit 2 . The holding member 3 has an imaging element 31 . The imaging element 31 is fixed to the holding member 3 . A filling hole 32 is provided on the holding member 3 . A plurality of filling holes 32 may be provided on the holding member 3 . exist figure 1 In, three filling holes 32 are provided. The lens unit 2 and the holding member 3 can be fixed at three points through the three filling holes 32 . The filling holes 32 are not limited to three.
[0038] With the lens unit 2 and the holding member 3 , the adhesive is filled from the filling hole 32 in a state where the lens 21 and the imagi...
Embodiment approach 2
[0064] The lens unit 2 may also have a rib 24 connecting the three bosses 22 .
[0065] Figure 6 The lens unit 2 shown has ribs 24 connecting three bosses 22 . Grooves 25 may be provided on the ribs 24 . The groove 25 can connect the hole 23 provided on the boss 22 . Ribs 24 and grooves 25 may be provided on at least a portion around the optical axis 5 . The ribs 24 and grooves 25 may be provided on the entire circumference around the optical axis 5 .
[0066] Figure 7 The camera assembly 1 is shown at the point where the lens unit 2 has ribs 24 and grooves 25, with image 3 The camera assembly 1 shown is different. The adhesive is filled from the filling hole 32 corresponding to the boss 22 , and spreads from the hole 23 to the rib 24 and the groove 25 . The filled adhesive is cured to form the joining member 4 . The joining member 4 may be formed on at least a part of the circumference of the optical axis 5 . The bonding member 4 may also be formed over the entire...
Embodiment approach 3
[0069] The lens unit 2 may not have the boss 22 .
[0070] Figure 8A The lens unit 2 shown has only holes 23 and no bosses 22 . Figure 8B The lens unit 2 shown in addition to having Figure 8A In addition to the structure, there is also a groove 25 connecting the hole 23.
[0071] Figure 9 The shown lens unit 2 does not have the boss 22 at this point and Figure 4 The lens unit 2 shown is different. The adhesive is filled from the filling hole 32 corresponding to the hole 23 and filled into the inside of the hole 23 . and Figure 4 Compared, Figure 9 The lens unit 2 shown has a wider space between the holding members 3 since it does not have the bosses 22 . Thereby, when the positional alignment of the lens unit 2 and the holding member 3 is performed, the movable range in the direction of the optical axis 5 can become wider.
