Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a correction optical device and an image stabilizing device mounted on an apparatus having a shake correcting function such as a camera.

[0002]

2. Description of the Related Art In a current camera, all operations important for photographing, such as exposure determination and focusing, are automated, so that even a person unskilled in camera operation is very unlikely to fail in photographing.

[0003] Recently, a system for preventing camera shake added to a camera has been studied, and a factor which causes a photographer to make a photographing error has almost disappeared.

Here, a system for preventing camera shake will be briefly described.

The camera shake at the time of photographing is generally a vibration of 1 Hz to 10 Hz as a frequency. At the time of the release of the shutter, even if such camera shake occurs, it is possible to take a picture without image shake. As an idea, it is necessary to detect the camera shake caused by the camera shake and to displace the correction lens according to the detected value.
Therefore, in order to take a photograph in which image shake does not occur even when camera shake occurs, first, it is necessary to accurately detect the camera vibration and, secondly, to correct the optical axis change due to camera shake. Become.

In principle, this vibration (camera shake) is detected by a shake detection sensor that detects acceleration, angular acceleration, angular velocity, angular displacement, and the like, and an output of the shake detection sensor is appropriately processed for camera shake correction. This can be performed by mounting a vibration detection device having a calculation unit on a camera. Then, based on this detection information, the correction optical device for decentering the photographing optical axis is driven to suppress image blur.

The details of an anti-vibration system having a vibration detecting device, a correction optical device, and the like are disclosed in Japanese Patent Application Laid-Open No. 2-58037. The outline thereof will be described with reference to FIG.

FIG. 7A is a perspective view of a compact camera equipped with an anti-vibration system.
Reference numeral 62 denotes a photographing lens of the camera, which is protected by a lens barrier when photographing is not performed (FIG. 7A shows the photographing state where the lens barrier is retracted and cannot be seen). Reference numeral 63 denotes a main switch of the camera. FIG. 7A shows a photographable state in which the image stabilizing system is turned on.
When the main switch 63 is set to the sports mode 64 (high-speed shutter mode) or the strobe mode 65, the camera is switched to a shooting enabled state in which the image stabilizing system is turned off. Switch (since such a mode does not require an anti-vibration system). Reference numeral 66 denotes a release button. When the release button 66 is depressed, the camera performs photometry and distance measurement, starts blur correction after focusing, and exposes the film. Reference numeral 67 denotes a strobe light emitting unit which automatically emits light when a subject is dark or forcibly emits light.

FIG. 7B is an internal perspective view of FIG. 7A, in which reference numeral 68 denotes a camera body, and reference numeral 69 denotes a correction for correcting vibration by driving a correction optical system 70 freely in the X and Y directions in the figure. Optical devices 71p and 71y are shake detection sensors for detecting shake 72p in the pitch direction and shake 72y in the yaw direction, respectively.
Reference numeral 73 denotes the above-described lens barrier, which opens and closes in conjunction with a knob 74 shown in FIG. The knob 74 is shown in FIG.
The main switch 63 is adjacent to the main switch 63, and when the main switch 63 is operated, the knob 74 is also pushed and the lens barrier 73 is opened. When the lens barrier 73 is in the closed state, the correction optical device 69 (specifically, a support frame supporting the correction optical system 70) is mechanically locked,
This prevents the correction optical device 69 from being violently damaged when not photographing, for example, when carrying it.

Reference numeral 110 denotes a support frame for holding the correction lens 114. As shown in FIG. 3, pins 111 (three places) are press-fitted. This pin 111 is attached to the support portion 19 of the main plate 19.
Slots 19ca formed at c (three places) (see FIG. 3)
Are fitted in a direction perpendicular to the optical axis 10. Therefore, the support frame 110 is restricted from moving in the direction of the optical axis 10 with respect to the base plate 19, but in other directions (arrows 12a and 12a in FIG. 1).
12b, 13p, 13y, and 13R).

As shown in FIG. 1, elongated holes 110b (three places) are provided on the back surface of the support frame 110, and the opposite side of the base plate 19 is shown in FIGS. 2 (a) and 2 (b). As described above, the long holes 19e (three places) orthogonal to the long holes 110b are provided.

Pin 113 of ring-shaped rotation retaining ring 113
As shown in FIGS. 2 (a) and 2 (b), a (three places) are fitted into the elongated holes 19e and 110b, respectively.
Accordingly, the rotation retaining ring 113 is moved by the arrow 13 y with respect to the main plate 19.
The support frame 110 can move only in the direction of the arrow 13p with respect to the rotation retaining ring 113.

From the above, the support frame 110 can freely move in the plane perpendicular to the optical axis with respect to the base plate 19, but the direction of the optical axis 10 and the rotation around the optical axis 10 (13)
R) is restricted from moving.

The hook 110a on the support frame 110
Tension springs 112a, 112b, 112c are provided between the (three places) and the hooks 19d (three places) on the main plate 19, and elastically support the support frame 110 with respect to the main plate 19.

Step motors 11a, 11b and 11c are provided on the base plate 19 at equal intervals of 120 degrees, and their rotors 14a, 14b and 14c (in FIG.
a and 14b are hidden behind the directly connected cam plates 15a and 15b) and the rotors 14a and 14b are
a, 15b, and the cam plates 15a, 15b are rotated. The rotor 14c has a shutter, an aperture, and a lens barrel drive (A
F, zoom, collapsing) are used as driving means of other elements of the camera.

A pin 16 is provided on the cam plates 15a and 15b.
a, 16b (locking portions) are provided, and leaf switches 17a, 17b on the step motors 11a, 11b are provided.
(The leaf spring portions 18a and 18b are precharged by the pins 11aa and 11ba) are turned on and off, and the rotation phases of the cam plates 15a and 15b are controlled by the on and off.

More specifically, the cam plate 15a is rotated clockwise in FIG.
7a is brought into contact with the leaf spring portion 18a. Also cam plate 15
b is rotated counterclockwise to bring the pin 16b into contact with the leaf spring 18b of the leaf switch 17b. At this time, the leaf spring portions 18 of the leaf switches 17a and 17b are
a and 18b are separated from the pins 11aa and 11ba, respectively (that is, the switch is off). When the correction optical device is used, the cam plate 15a is slowly rotated counterclockwise (the cam plate 15b is counterclockwise) so that the leaf spring portions 18a and 18b of the leaf switches 17a and 17b contact the pins 11aa and 11ba, respectively. When the switch is turned on (when the switch is turned on), the drive pulses of the motor are measured, and the rotational positions of the cam plates 15a and 15b are determined.

A support frame 11 is provided on the cam plates 15a and 15b.
The zero smoothing portions 110ca and 110cb are in contact with each other. The support frame 110 is elastically supported on the base plate 19 by tension springs 112a, 112b, and 112c.
The supporting frame 110 is not supported at the center of the main plate 19 by the base frame 12c. The tensile force of the tension spring 112a is stronger than other springs, and the supporting frame 110 is suspended above the plane of FIG. Parts 110ca, 110
cb is pressed against the cam plates 15a and 15b. Therefore, when the cam plates 15a and 15b rotate, the support frame 110 moves in the directions of the arrows 12a and 12b by the lift.

Incidentally, the cam plates 15a, 15c of the smooth portions 110ca, 110cb by the tension springs 112a to 112c.
b and the combined spring constant of the pressing direction against the support frame 11
The natural frequency determined by 0 and the mass of the moving unit such as the correction lens 114 is higher than the frequency band of camera shake, for example, 10H
z or more. This is because the cam plates 15a, 15
b is for causing the smoothing portions 110ca and 110cb to follow in response to the rotation in accordance with the camera shake, and if the natural frequency is set to 5 Hz, the cam plates 15a and 15b are adjusted to correct the camera shake of 10 Hz. This is because the smoothing portions 110ca and 110cb jump and do not follow.

A shake detection sensor 21a, 2 for detecting shake
1b are set to have an inclination of 60 degrees from each other as shown in FIG.

Here, the shake detection direction of the shake detection sensor 21a is around the arrow 22a, and in order to correct the shake in this direction, the correction lens 114 is moved by the shake detection sensor 21a.
It is necessary to drive in the direction of arrow 12a orthogonal to the mounting of a. Accordingly, the output of the shake detection sensor 21a is appropriately calculated and input to the step motor 11a to control the cam plate 15a to perform shake correction in this direction. Shake detection sensor 21
Similarly, the output b is input to the step motor 11b, and the correction lens 114 is input in the direction of the arrow 12b to perform correction in this direction.

Since the angle between the arrows 12a and 12b is 120 degrees, the shake detecting sensors 21a and 21
The installation angle of b is 60 degrees.

The correction lens 114 can perform shake correction in all directions (excluding the vicinity of the optical axis) in a plane orthogonal to the optical axis 10 by combining these in order to perform shake correction in two directions indicated by arrows 12a and 12b. become.

In the correction optical device described above, two step motors 11a, 1 for driving the shake correction means (comprising movable parts such as the support frame 110 and the correction lens 114).
1b, tension springs 112a to 112c for elastically supporting the shake correcting means are provided, so that the entire apparatus can be reduced in size, and extra components other than the apparatus, such as a camera shutter and an aperture in this example, are provided in an extra space. It is possible to provide a driving means for driving the camera and the like, and as a result, the size of the camera itself can be reduced.

By arranging these arrangements at equal intervals of approximately 120 degrees, it is possible to accommodate the step motors 11a to 11c having the same shape in a well-balanced manner.

The leaf switches 17a, 17 functioning as reset switches are provided on the cam plates 15a, 15b.
b pins 16a, 1 contacting leaf spring portions 18a, 18b
6b, and the leaf springs 18a, 18b of the leaf switches 17a, 17b are also provided on the step motors 11a, 11b, so that the reset mechanism can be reliably operated with a small number of parts, and highly accurate shake correction is possible. Became.

The tension springs 112a to 112c for elastically supporting the support frame 110 are connected to the cam plates 15a, 15b and the support frame 1a.
The force in the contact direction of 10a is increased, and the natural frequency determined by the spring constant in that direction and the mass of the shake correcting means is set higher than the frequency band of the camera shake (10 Hz or more). Has high follow-up performance, and can perform shake correction with high accuracy.

(Second Embodiment) FIGS. 4 and 5 are views showing a configuration of a correction optical device according to a second embodiment of the present invention. More specifically, FIG. 4 is a front view of the correction optical device. FIG. 5 and FIG. 5 are perspective views of the correction optical device.

FIG. 4 differs from FIG. 1 in that the tension springs 112b and 112c are eliminated.
Therefore, the support frame 110 is pressed against both the cam plates 15a and 15b only by the extension spring 112a.

In FIG. 1, three tension springs 112a are provided.
Since the support frame 110 was elastically supported in eight tears at -112c, the rotation in the direction of the arrow 13R was also restricted by the elastic force. In the configuration of FIG.
Elastic rotation control cannot be performed because of one of 12a. Of course, rotation is restricted in the direction of arrow 13R due to the presence of the rotation retaining ring 113, but some play in the rotational direction occurs due to fitting play or the like.

However, in the case of an optical design that allows such a play (when a photographing optical system having a lens sensitivity is designed so that the rotational play does not affect the film surface accuracy), the above-described method is used. As in the second embodiment, there are significant advantages in that the number of tension springs is reduced to one, the cost is reduced, the assemblability is improved, and adjustment of the spring balance is not required.

FIG. 5 is a diagram showing the arrangement of the correction optical device and the shake detection sensor. The difference from FIG. 3 is that the shake detection sensors 21p and 21y are arranged orthogonally. The difference is that the angle formed by the step motor is approximately 120 degrees (the shake detection direction for that is 60 degrees as described with reference to FIG. 3).

The target value calculation circuit 41 in FIG. 5 drives the pair of step motors 11a and 11b so as to move the support frame 110 in the directions of arrows 13p and 13y based on the outputs of the pair of shake detection sensors 21p and 21y. .

The direction of sensitivity of the shake detection sensor 21p is indicated by an arrow 2
2p, and it is necessary to move the correction lens 114 in the direction of the arrow 13p in order to correct the shake in this direction.
In order to move the correction lens 114 in the direction of the arrow 13p, as is apparent from FIG. 4, the cam plates 15a and 15b may be rotated by the same amount in opposite phases (one clockwise and the other counterclockwise). . Accordingly, the target value calculation circuit 41 performs signal processing so that the output of the shake detection sensor 21p is equally input to the pair of stepping motors, but is input as the opposite phase target value.

Similarly, the sensitivity direction 2 of the shake detection sensor 21y
In order to correct the shake of 2y, the correction lens 114 is moved by the arrow 1
Move in the direction of 3y. And for that, the cam plate 1
What is necessary is to rotate 5a and 15b in the same phase by the same amount. Therefore, the target value calculation circuit 41 is
The output of 1y is equally processed by a pair of step motors, and is signal-processed so as to be input as an in-phase target value.

Of course, the target value calculation circuit 41 adjusts the gain of the output of the shake detection sensors 21p and 21y and, if necessary, adjusts the frequency (high-pass filter, low-pass filter, integration), and shakes the step motors 11a and 11b. The total of the target values from the detection sensors 21p and 21y is input, and the step motor is driven.

With the above configuration (providing the target value calculation circuit 41), the degree of freedom in the arrangement of the shake detection sensor can be increased, and the entire camera including the image stabilizing system can be reduced in size. .

(Third Embodiment) FIG. 6 is a front view of a correction optical device according to a third embodiment of the present invention.
The difference is that, instead of the step motors 11a and 11b, yokes 51a and 51b (51a are omitted), permanent magnets 52a and 52b (52a are omitted), and coils 53a and 53b are provided. is there.

The yokes 51a and 51b are both supported by the support frame 110.
The permanent magnets 52a, 52
b is magnetically coupled to the yokes 51a and 51b, respectively. Coils 53a and 53b are provided on the base plate 19 side, which is a surface facing the permanent magnets 52a and 52b, and the direction of the coil current is indicated by an arrow 53aa (of course, the direction of the coil current can also be supplied in the opposite direction).

The magnetization directions of the permanent magnets 52a and 52b are perpendicular to the plane of the paper, and the arrangement of the magnetic poles is indicated by arrows 52ba and 52ba.
52bb. Therefore, the coils 53a, 5
When a current is passed through 3b, the support frame 110 is moved according to Fleming's law.
Are driven in the directions of arrows 12a and 12b.

As in the first and second embodiments, since there is no need to urge the support frame 110 against the cam plate, the spring forces of the three tension springs 112a to 12c are equally divided. The support frame 110 is spring-balanced to the center position of the main plate 19. The fact that the natural frequency is set to be equal to or higher than the band of camera shake is the same as in the first and second embodiments.

As described above, the present invention can be applied to other than the step motor, and it is possible to arrange the step motor of elements other than the correction optical device in the surplus space.
