Detailed Description
An imaging device embodying the present invention will be specifically described below with reference to the drawings.
Fig. 1 is an explanatory diagram showing a configuration of an imaging device according to embodiment 1 of the present invention. As shown in the figure, the imaging device includes: a lens unit LU; a holder 10 that holds the lens unit LU; and a solid-state imaging device S such as a CMOS or a CCD, which receives the light beam after passing through the lens.
The lens unit LU includes: lenses L1 to L8; an optical filter F; a lens frame 20 having a lens housing portion 21 for housing and holding a lens; a front side pressing ring 30 for pressing and fixing the lenses L1 to L3 to the lens frame 20; a rear side press ring 60 for pressing and fixing the lenses L4 to L8 to the lens frame 20, and having a fitting portion 63 for fitting the optical filter F and holding the optical filter F; and a biasing spring 70 having elasticity and biasing the lenses L4 to L8 toward the image side.
The screw portion 32 of the front pressure ring 30 is screwed to the front screw portion 23a of the lens frame 20, and the screw portion 62 of the rear pressure ring 60 is screwed to the rear screw portion 24 of the lens frame 20. The rear side pressure ring 60 is provided with a lens pressing portion 61 that presses the lens 8.
As shown in fig. 3 and 4, the urging spring 70 is a wave washer-shaped leaf spring that is compressed in the plate thickness direction between the contact portion 27 of the lens frame 20 and the contact portion L51 of the lens L5, and the urging spring 70 urges the lenses L4 to L8 toward the image side.
As shown in fig. 1, a 1 st spacer ring 40 is provided between the lens L6 and the lens L7, and a 2 nd spacer ring 50 is provided between the lens L7 and the lens L8.
The holder 10 holds the lens unit LU so as to be movable in the optical axis direction by screwing the screw portion 12 to the front screw portion 23b of the lens frame 20, and the circuit board mounting portion 11 of the holder 10 is fixed to a circuit board, not shown, on which the solid-state imaging element S is mounted, by a fixing method such as screw fixing or bonding.
The solid-state imaging device S has a cover glass S1 and an imaging surface S2, and a circuit board connection portion S3 of the solid-state imaging device S is electrically connected to a circuit board not shown.
The holder 10 further includes a front fitting portion 13a and a rear fitting portion 13b, which are two fitting portions of the lens unit LU in which the lens unit LU is fitted and held so that the lens unit LU can be moved in the optical axis direction, the front fitting portion 13a being fitted to the front fitting portion 25a of the lens frame 20, and the rear fitting portion 13b being fitted to the rear fitting portion 25b of the lens frame 20. This makes it possible to stably hold the lens unit LU so that the optical axis a of the lens unit LU is perpendicular to the imaging surface S2.
The screw portion 12 is provided on the subject side of the intermediate portion between the front fitting portion 13a and the rear fitting portion 13b, and the front screw portion 23b is provided on the subject side of the intermediate portion between the front fitting portion 25a and the rear fitting portion 25b, and the distance between the two fitting portions, that is, the front fitting portion 13a and the rear fitting portion 13b, and the distance between the two fitting portions, that is, the front fitting portion 25a and the rear fitting portion 25b, are 1/2 or more of the total lens unit length, that is, the meshing portion center point 13c of the screw portion 12 and the front screw portion 23b is provided on the subject side of the intermediate portion of the total optical length TL of the imaging device, so that inclination of the optical axis such as shift of the focal position of the lens can be prevented even when external side pressure or the like is applied to the lens unit. Here, as shown in fig. 1, the optical full length TL of the imaging device is a distance from the lens optical system tip, that is, the lens tip, to the imaging surface S2.
The holder 10 is provided with an adhesive portion 14 penetrating the side surface of the holder 10 so as to expose the lens frame 20 to the outside, and the adhesive B is applied to the adhesive portion 14, whereby the lens unit LU can be adhesively fixed to the holder 10 between the front end surface 14a of the adhesive portion 14 and the adhesive portion 26 of the side surface of the lens frame 20 and between the rear end surface 14B of the adhesive portion 14 and the adhesive portion 26 of the side surface of the lens frame 20. As shown in fig. 2, the adhesive portions 14 are provided at 3 positions every 120 ° in the circumferential direction of the holder 10. The lens unit LU may be directly bonded by the bonding portion 14, or the other member may be bonded by the bonding portion 14 and the lens unit LU may be fixed via the other member.
The advantages of this bonding method are explained. Conventionally, in an imaging device with a fixed focus, there is a problem that the focus position of a lens is shifted due to a temperature change, and movement of a lens unit is caused by expansion and contraction of an adhesive.
For example, in patent document 2, the lens unit and the holder are screwed together by screws, and there is a possibility that screw loosening occurs, and the lens unit is moved in the optical axis direction by an amount corresponding to the screw loosening due to expansion and contraction of the adhesive caused by a temperature change, resulting in a focus position shift.
According to the bonding method of the present invention, even if the adhesive B expands or contracts due to a temperature change, the lens unit LU is not moved in the optical axis direction due to the restriction of the front end surface 14a and the rear end surface 14B of the bonding portion 14 of the holder 10, and the focal position can be stably maintained. The bonding is characterized by low cost and simplicity, but it is needless to say that the bonding may be performed by screwing by providing a screw or the like from the side as in the conventional method.
In addition, patent document 4 proposes the following method: the relationship between the lens holder (holder) and the focal distance of the lens barrel (frame), collet, lens is set such that,
Lc·CTEc＝Lm·CTEm+Lb·CTEb-Lf·CTEf
wherein Lc: length of collet, lm: length of lens holder, lb: length of lens barrel, lf: focal distance of lens, CTEc: thermal expansion coefficient, CTEm: thermal expansion coefficient of lens holder material, CTEb: thermal expansion coefficient of lens barrel material, CTEf: the rate of change of the temperature of the lens,
this makes it possible to maintain the focal position even when the temperature changes. That is, the movement of the holder and the lens frame that expand and contract in the same direction from the imaging surface is canceled by the expansion and contraction in the opposite direction of the collet when the temperature changes.
In contrast, according to the present invention, since the holder 10 and the frame 20 are fixed to each other by the screw portion 12, the front screw portion 23b, and the adhesive portions 14 and 26 on the side of the subject from the middle portion of the lens unit LU, the holder 10 and the frame 20 expand and contract in the opposite direction from the imaging surface S2 when the temperature changes. In the present invention, therefore, the relationship between the holder 10 and the back focal length of the lens frame 20 and the lens is set as follows,
Lh·CTEh＝Lb·CTEb-bf·CTEf
wherein Lh: length of the holder, lb: length of the frame, bf: back focal length, CTEh: thermal expansion coefficient of the holder material, CTEb: thermal expansion coefficient of the frame material, CTFf: the rate of change of the temperature of the lens,
CTFf is determined by the characteristics of the entire optical system including the total optical length TL.
This makes it possible to maintain the focal position even when the temperature changes, and therefore, a collet is not required, and the cost can be reduced.
Here, as shown in fig. 1 and 6, the holder length Lh is a distance from the engagement portion center point 13c between the screw portion 12 of the holder 10 and the front screw portion 23b of the lens frame 20 to the imaging surface S2, and the lens frame length Lb is a distance from the engagement portion center point 13c between the screw portion 12 of the holder 10 and the front screw portion 23b of the lens frame 20 to the rear surface of the 8 th lens L8. The back focal length bf is a distance from the rear surface of the 8 th lens L8 to the imaging surface S2.
Fig. 6 is an explanatory diagram showing a configuration of an imaging device according to embodiment 2 of the present invention, and is a modification of the imaging device according to embodiment 1 of the present invention in which a screw portion 12 is provided between a front fitting portion 13a and a rear fitting portion 13b, and a screw portion 23 is provided between a front fitting portion 25a and a rear fitting portion 25b.
Fig. 7 is an explanatory diagram showing a configuration of an image pickup apparatus according to embodiment 3 of the present invention, and is a modification of the image pickup apparatus according to embodiment 1 of the present invention, which does not include the front-side fitting portion 13a and the front-side fitting portion 25 a.
In embodiment 2, since the meshing portion center point 13c between the screw portion 12 and the front screw portion 23b is provided on the side of the subject than the intermediate portion of the total optical length TL of the imaging device, the optical axis is slightly less accurate than in embodiment 1, but the inclination of the optical axis such as the shift in the focal position of the lens can be prevented even when external side pressure or the like is applied to the lens unit as in embodiment 1.
In addition, in the present invention, since the urging spring 70 that has elasticity and urges the lenses L4 to L8 toward the image side is provided, even if a gap occurs due to a difference in thermal expansion coefficient between the lens frame 20 and the lenses L4 to L8 at the time of temperature change, the gap can be prevented from being loosened between the lenses, and the 8 th lens L8 can be ensured to be positioned closer to the sensor, so that the back focal length bf can be stably maintained.
In addition, the elastic member is provided between the 6 th lens L6 and the 7 th lens L7 or between the 7 th lens L7 and the 8 th lens L8, and also can prevent looseness from occurring between lenses due to a gap generated by a difference in thermal expansion coefficient, and can stably maintain the back focal length bf.
As shown in fig. 5, the rear side pressure ring 60 and the 8 th lens L8 are bonded and fixed by the lens bonding portions L8a and 64, and therefore lens loosening due to thermal expansion cannot be prevented, but the 8 th lens L8 can be ensured to be always positioned closer to the sensor, and thus the back focal length bf can be stably maintained. The adhesive fixation may be performed between the frame 20 and the 8 th lens L8.
Next, another advantage of the bonding method will be described with reference to fig. 8. Fig. 8 is an explanatory diagram showing the configuration of an image pickup apparatus according to embodiment 4 of the present invention, and is a modification of the image pickup apparatus according to embodiment 1 of the present invention described above, and is an example of an image pickup apparatus having a waterproof structure. The portions common to the imaging device according to embodiment 1 of the present invention will not be described.
The lens unit LU includes an elastic sealing member 80 compressed in the radial direction (in the direction perpendicular to the optical axis) between the side reduced diameter portion L1a of the 1 st lens L1 and the L1 fitting portion 21a of the lens frame 20, thereby ensuring water repellency in the lens receiving portion 21 of the lens frame 20.
The image pickup apparatus further includes a sealing member 90 having elasticity compressed only in the optical axis direction between the front end portion 15 of the holder 10 and the housing 100, thereby ensuring water repellency of the peripheral portion of the image pickup apparatus.
Here, since the position of the lens unit adhesive fixing portion located at the front end portion of the holder in the conventional example is located at the adhesive portion 14 which is the through hole facing the side surface of the holder 10 to the lens unit LU in the present invention, the sealing member 90 does not interfere with the adhesive B, and the waterproof property can be ensured.
In addition, according to this waterproof structure, even when misalignment occurs between the lens unit LU and the case 100 due to part errors, the side pressure is not applied to the lens unit LU by the elastic force of the sealing member 90, and therefore the focal position of the lens can be stably maintained.
