Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-shake camera having a device for correcting camera shake of a photographer.

[0002]

2. Description of the Related Art Conventionally, various techniques relating to a camera for preventing image quality deterioration due to camera shake of a photographer have been proposed.
For example, the camera shake warning is given to the photographer when the shutter speed is slow to cause camera shake, or the program diagram is shifted to the high speed shutter. The amount of light is detected and the shutter timing is controlled so that there is less camera shake during exposure, or the camera shake is actively corrected to compensate for the detected camera shake. A technique for stabilizing a subject image on the film surface by tilting or displacing a photographing lens (camera shake correction lens) as a part in a direction orthogonal to the optical axis is also known and has already been commercialized.

Further, there has been proposed a conventional technique for preventing camera shake by displacing an element other than the camera shake correction lens. For example, the technology disclosed in Japanese Patent Laid-Open No. 3-121430 prevents camera shake by using an anti-vibration grip in the shape of a motor drive that can mount the entire camera and can drive the entire camera in a direction orthogonal to the optical axis. According to this technique, the photographer attaches the camera to the anti-vibration grip and holds the anti-vibration grip, not the camera itself, to take an image.

Further, in Japanese Unexamined Patent Publication No. 64-78241, a film holding member 151 that holds the exposed surface of the film 150 and is displaceable in a direction orthogonal to the optical axis is provided, and the holding member 151 is used as a sprocket 152. At the same time, a technique for displacing the camera shake so as to cancel the camera shake is disclosed (see FIGS. 2A and 2B).

[0005]

However, in the camera for displacing a part of the taking lens according to the prior art, when the displacement of the lens is small, there is no problem, but the camera shake amount becomes large and the lens displacement amount becomes large. Then, the optical aberration becomes large. Conversely speaking, there is a problem that camera shake correction can be performed only in a range where optical aberration is inconspicuous, and the correction range cannot be large. In addition, it is necessary to design an image stabilization lens for each lens.

In the technique disclosed in Japanese Patent Laid-Open No. 3-121430, although the above-mentioned problems are solved, the whole camera, which is a large object having a mass of several hundred grams, is driven, and the actuator is The drive system including is large. Therefore, when the camera is attached, the entire device becomes large and it becomes difficult to carry it.

Further, the technique of driving the film according to the amount of camera shake disclosed in Japanese Patent Laid-Open No. 64-78241 solves the above-mentioned problems and improves the accuracy in photographing the first frame. Good image stabilization is done. However, in shooting the second and subsequent frames, the initial position of the film remains at the position where the previous camera shake correction was performed, and the camera shake correction is relatively performed from that position. Therefore, the positions of the front and rear frames may vary on the film. Further, since the film holding member holds only the periphery of the exposed surface of the film and drives it and does not drive the entire film, the film is always held in a plane orthogonal to the optical axis and is not rotated about the optical axis. In order to achieve this, it is necessary to hold the exposed surface of the film with a film holding member so that there is no play, which is difficult in terms of design.

The present invention has been made in view of the above problems, and detects the camera shake of the photographer and holds the entire film including the cartridge and the film winding mechanism and rewinding mechanism around the film.

Before explaining the peripheral mechanism of the holding member 7 of the present invention, a mechanical mechanism for freely driving an object in the X-axis and Y-axis directions will be described. FIG. 7 shows a mechanism for driving the load 75 by a motor and a power transmission mechanical mechanism.
A biaxial drive mechanism that can be driven in the X-axis direction and the Y-axis direction,
Since the mechanism is exactly the same, only the X-axis direction will be described. Code 5
Reference numeral 4 is a motor which is a drive unit. The gear train that transmits the driving force from the motor 54 includes gears 76, 77, 78 and 79. The rotation of the bearings 81, 8 provided on the frame 80
2 is transmitted to a shaft 83 that is rotatably supported around the X axis.

The motor 54 is fixed to the frame 80,
The gears 76 to 78 are fixed to the frame body 80 through gear shafts 84 to 86, respectively. The final gear 79 can rotate integrally with the shaft 83. In the connecting member 87, the internal thread portion 88 provided on itself is the external thread portion 8 of the shaft 83.
Slotted holes 90 and 91, which are screwed into 9 and are parallel to the Y-axis direction.
Are formed, and bosses 92 and 93 provided on the load 75 are engaged with these elongated holes.

Therefore, the load 75 includes the motor 54 and the gear 76.
~ 79, the shaft 83, and the connecting member 87 drive in the X-axis direction, but at this time, they are free in the Y-axis direction. Also,
It is driven in the Y-axis direction by a similar mechanism, but at this time, it is free in the X-axis direction. Therefore, the load 75 is the frame 80
It can be driven in all directions inside the. Load 7 at this time
The movement speed of No. 5 is performed by the PIs 52 and 53 as described above.

Next, a mechanism for driving the load 75 in the frame 80 with low friction will be described. FIG. 8 is a sectional view of FIG. 7 taken along the plane AA ′. The load 75 is engaged with the inside of the frame body 80 as shown in the figure, and a groove 96 is dug in the surface 95 of the frame body 80 to reduce friction. By sandwiching the load 75 and the groove 96 on the frame 80 via rollers 97, the load 75 is supported so as to be drivable with low friction. A mechanism that can be driven with low friction can be obtained by providing a mechanism using such grooves and rollers at a minimum of 4 locations on one surface of the load 75 and a minimum of 4 locations on the other surface, a total of 8 locations.

When the mechanism capable of freely driving in the XY plane with low friction as described above is applied to the camera-shake preventing camera of the present invention, the frame body 80 is replaced with the camera body, and the load 75 is replaced with the holding member 7. Good.

Next, FIG. 9 shows a view of the peripheral mechanism of the holding member 7 of the anti-shake camera of the first embodiment as seen from the back side with the film 4 loaded. In the figure, the member shown by hatching in the lower right is the camera body 100, and the body 100 is provided with an X-axis rotation angular velocity sensor 3x and a Y-axis rotation angular velocity sensor 3y. The member shown by hatching in the lower left is the holding member 7, and the holding member 7 has two mechanical mechanisms of a motor and a gear that can drive the holding member 7 already described in FIG. 7 in the X-axis direction and the Y-axis direction. It is provided in.

The mechanical mechanism of the motor and the gear is fixed to the main body 100, and the holding member 7 can be freely driven in the XY plane. Further, the holding member 7 includes a motor 101 for winding the film 4, a gear 102 and a gear 1 therefor.
03 and the shaft 104 are fixed, and the film 4 can be wound up. Further, the rewinding motor 105 for the film 4, the gear 106, the gear 107, and the shaft 108 for that are fixed to the holding member 7, so that the film 4 can be rewound.

Since winding and rewinding are not performed at the same time, it is also possible to adopt a structure in which the motor can be shared and the gears can be switched. Further, winding and rewinding may be done manually. Further, the film 4 has its exposed portion on the pressure plate 4
It is held down at 0, ensuring flatness. This pressure plate 40 is attached to the back cover 109 as in a general camera, but when the back cover 109 is closed and four electromagnets 110 to 113 are attached to the holding member 7 and the exposed portion of the film 4 is pressed in a photographing state. It is like this.

When the film 4 is wound or unwound, it is necessary to release the pressure of the film 4 by the pressure plate 40. At this time, the electromagnets 110 to 113 may be turned off. A method of mechanically releasing or compressing the film 4 by the pressure plate 40 without using an electromagnet is known from JP-A-5-72592, and may be mechanically performed. Further, the pressure plate 40 is also structured to be movable in the XY plane with low friction by the mechanism using the above rollers.

Further, the holding member 7 includes springs 114 and 115.
Is pulled to the left of the paper by the springs 116 and 117.
It is pulled downward on the paper. These springs 114-
The role of 117 is to reduce the rattling at the time of driving and to reduce the backlash of the gear by always pulling the holding member 7 in a fixed direction.

Next, FIG. 10 is a sectional view taken along line BB 'in FIG.
Will be explained. In the figure, the holding member 7 has a structure with a hole in the film exposure portion,
Grooves and rollers 120 to pillars 118 and 119 provided at 0
It is installed via 123. The structure using this roller is as already described in FIG. With such a structure, the holding member 7 can be freely driven in the XY plane with low friction.

Although the first embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the present invention. For example, the mechanism for driving the holding member 7 may be any mechanism as long as it converts the rotational movement of the motor into linear movement. For example, a structure using a gear and a cam may be used. The structure using rollers is not necessary as long as it can be driven with low friction, but the structure using rollers is optimal when priority is given to low friction.
Furthermore, even if the actuator is not a DC motor, it is USM
Alternatively, a piezoelectric element may be used, but a DC motor is superior in view of low cost, and a coreless motor having a fast response is particularly suitable.

The camera shake detection sensor may be an acceleration sensor, an angle sensor, or an AF sensor instead of the angular velocity sensor. However, considering that the angular velocity of the camera and the image moving speed are closely related to each other, as will be described later, the angular velocity sensor. Is excellent. Then, the sensor that also serves as the AF sensor has a problem that it becomes difficult to use when the brightness is low. Further, in the case of a camera capable of imprinting the date, the date imprinting module may be driven simultaneously with the holding member 7 in order to always record the date at a fixed position on the film. There is also a film that has been made into a cartridge type for a small camera from the past.

FIG. 11 shows a schematic view of the holding member 7 as seen from the lower part of the camera body when the film is loaded.
As shown in FIG. 11, the cartridge type film 160 has a film stored in a plastic case, and the cartridge type film 160 is loaded into the camera together with the plastic case. Therefore, when such a cartridge type film 160 is used in the present invention, the pressure plate 40 is not necessary, and the mechanism becomes simpler.

Next, a second embodiment of the present invention will be described. The second embodiment is an embodiment using a magnetically recordable film capable of recording various information of photographing. Since the film is smaller than the conventional film, the camera body is also smaller than the conventional one. Only the points different from the first embodiment will be described below.

First, FIG. 13 shows a conceptual diagram of an anti-shake camera according to the second embodiment, which will be described. As shown in the figure, in addition to the configuration of the first embodiment, the anti-shake camera of this embodiment includes a magnetic recording head 13 for magnetically recording information on a magnetic recording track of a magnetically recordable film 12. It has a magnetic recording controller 14 for recording information on the magnetic recording head. The magnetic recording control unit 14 comprises a magnetic recording control circuit and a magnetic recording control microcomputer. The control method for magnetic recording is not directly related to the gist of the present invention, and therefore its explanation is omitted. The magnetically recordable film 1
2, the film rewinding unit 5, the film winding unit 6, and the magnetic recording head 13 are fixed to a holding member 7, and the holding member 7 can freely move in the XY plane at right angles to the Z axis with respect to the camera body. It has a mechanism that can move in any direction.

The state of loading the film 12 into the camera body is as shown in FIG. 12, and unlike the conventional camera using the film, the large back cover 109 is eliminated.
The camera body 10 has a small lid 15 for loading the film 12.
It can be seen from the figure that it is open to the back or the bottom of 0.

Next, FIG. 14 shows a schematic view of the holding member 7 as seen from the bottom of the camera body when the film 12 is loaded. In the figure, reference numeral 12 is a magnetically recordable film,
Reference numeral 161 is a cartridge, 13 is a magnetic recording head, 40 is a pressure plate for pressing the film exposure portion, 162 is a film guide,
163 is a winding roller. All of these members are held by the holding member 7, and the holding member 7 is driven so as to cancel the camera shake of the photographer with low friction in the XY plane with respect to the camera body 100 (not shown in FIG. 14). Is the same as the embodiment described above.

Next, referring to FIG. 15, the relationship between the camera shake amount and the camera shake correction amount, that is, the relationship between the camera shake speed and the drive speed of the holding member 7 will be described. FIG. 15 shows YZ of an image when the camera body 1 is rotated by a camera shake by a rotation angle θx.
FIG. 13 is a simplified diagram showing a movement state on a plane, which is denoted by reference numeral 130.
Is the subject. When the camera body 1 rotates by θx due to camera shake, the photographing optical system 2 rotates from the position 2 to the position 2 ′, and the film surface 131 also rotates to the position of the CD surface. At this time, the central position 1 on the film surface 131
A CD in which the image of the subject 130 in 32 is rotated by θx
Move to position 132 'on the surface. In FIG. 15, the focal length of the photographing optical system 2 is f, the distance from the subject side focus to the subject 130 is L, and the image side focus is at the image position 13
Let L ′ be the distance to 2 and Δ be the thickness of the photographic optical system, and Δ
Is sufficiently negligible compared to L. At this time, the amount of camera shake, that is, the amount of image movement ΔY on the film surface 131 is expressed by the following equation.

ΔY = (1 + β) ² · θx · f (1) However, β is an imaging magnification and β = f / L. F in the above formula (1) can be obtained as zoom information, and L
Is information that can be obtained from the focus detection unit 32. However, except for close-up photography such as macro photography, β << 1
Therefore, the above equation (1) is simplified as the following equation.

[0056]

[Equation 1]

By correcting the image movement amount based on the equation (1) or the equation (2), it is possible to perform photography that does not affect the photograph even if camera shake occurs.
Although the image plane is tilted by an angle θx with respect to the Y axis, θx is generally considered to be 0.1 deg or less, so the problem of out-of-focus is not a particularly serious problem. Further, of course, the rotation angle θy about the Y-axis also has the same formula, so the description thereof is omitted. Next, the above equations (1) and (2) are time-differentiated to obtain the following equation. d (ΔY) / dt = (1 + β) ² · f · d (θx) / dt (3)

[Equation 2]

In the above equation, d (θx) / dt is the angular velocity itself, and the output of the X-axis rotation angular velocity sensor 3x can be applied as it is. Further, d (ΔY) / dt is the image moving speed Vy in the Y-axis direction when an angular velocity of d (θx) / dt occurs.

Therefore, in order to correct camera shake, the holding member 7
If the object is moved at a speed of Vy in the Y-axis direction and at a speed of Vx in the X-axis direction, the subject image is stationary on the film surface. The above calculation is performed by the drive amount calculation unit 10.

Next, the operation of the anti-shake camera according to the second embodiment will be described with reference to the flow charts of FIGS. First, referring to the flowchart of FIG. 16, the MCO
The operation of M20 will be described.

As described above, the MCOM 20 is a microcomputer that performs the sequence of the entire camera and various calculations. When the main switch of the camera is turned on by the user, the MCOM 20 is power-on reset and starts operating, and first, the I / O port is initialized and the memory is initialized (step S1). Then, the photometric processing circuit 25
The brightness information of the subject is input from the device, the aperture value and the shutter speed are calculated from the information and the film sensitivity information (step S2), and the data is displayed using the display circuit 21 (step S3).

Then, the state of the first release (1R) is judged (step S4). Here, the anti-blurring camera of the present embodiment has two stages of release, and focus detection and the like are performed by half-pressing the release (first release 1R), and exposure is performed by fully pressing (second release 2R). If 1R is off, it is determined in step S5 whether to shift to the standby mode. This is step S1
Determine whether the timer set in step 6 has overflowed. This timer is set to overflow, for example, in a few minutes. Here, the standby mode is a mode in which the energy of the battery is not wasted, and during the mode, the microcomputer stops the operation or reduces the operation speed to reduce power consumption. At this time, the circuit operations other than the MCOM 20 are also stopped.

The standby mode is released by the user pressing any one of the operation switches 22 again,
The operation is restarted from step S2. If the standby mode is not entered, the process returns to step S2 (step S2).
5).

On the other hand, if 1R is turned on in step S4, the process proceeds to step S6. Then, the focus shift amount is detected based on the data output from the focus detection unit 32 (step S6), and the focus adjustment lens 33 is driven by the focus adjustment unit 35 to adjust the focus (step S).
7). Focusing takes a long time when the subject has low contrast or low brightness. Subsequently, it is determined whether the focus adjustment in step S7 is completed (step S8). If the focus adjustment is not completed, the process returns to step S6, and if it is completed, it is determined whether the 2R is turned on. (Step S9).

Even if 2R is off in step S9, the process returns to step S6 to repeat the focus adjustment. Then, when 2R is turned on, it is determined whether the camera shake prevention mode is set (step S10). The mode is selected by the photographer in advance and is provided on the operation switch 22. The mode is not selected when the camera is set on a tripod or when the photographer does not want to intentionally prevent camera shake. Then, if it is not in the mode in step S10, the process proceeds to step S13, and if it is in the mode, the process proceeds to subsequent step S11.

Then, the image stabilization start signal is output to the microcomputer SCOM50 in the image stabilization circuit (step S11). As will be described later, the SCOM 50 starts camera shake prevention after receiving the signal. Then, it is determined whether the exposure start signal is output from the SCOM 50, and the process waits until the signal is output (step S12). As will be described later, since the holding member 7 is driven from the stopped state in the initial state, it is more accurate to start the exposure after the run-up is performed in advance so that the current image moving speed and the driving speed of the holding member 7 match to some extent. Good image stabilization is achieved.

Thus, when the exposure start signal is output from the SCOM 50, the mirror control unit 26 is controlled to control the mirror 2
7 is increased (step S13). Further, the aperture controller 30 is controlled to set the aperture 31 to the value calculated in step S2 (step S14). Then, the shutter controller 28 is controlled to open the shutter 29 for the time calculated in step S2 (step S15). Then, after the exposure is finished, it is determined again whether the camera shake prevention mode is set (step S
16) If it is not the mode, the process proceeds to step S18. Then, in the case of the mode, the image stabilization stop signal is output to the SCOM 50 (step S17), and the process proceeds to step S18. And the mirror 27 that is up
Is lowered (step S18), and the diaphragm 31 is set to open (step S19). Finally, the film is wound up one frame (step S20), and the main routine of MCOM20 is ended.

Next, referring to the flowchart in FIG. 17, S
The operation of the COM 50 will be described. As mentioned above, SCOM5
Since 0 is a microcomputer exclusively for camera shake prevention, its operation is not started until the image stabilization start signal is output from the MCOM 20 (step S30). When the signal is output, the SCOM 50 executes a subroutine image stabilization (step S31). This subroutine drives the holding member 7 at the image moving speed to prevent camera shake, and will be described in detail later. At the time of execution of step S31, since the exposure is not yet started, the subroutine is used for running the holding member 7. The purpose is as described above.

Then, whether the running of the holding member 7 is completed,
That is, it is determined whether the moving speed has reached the current image moving speed (step S32). Steps S31 and S above
Since the processing time of 32 becomes the shutter time lag as it is, it is ideal that the processing time is as small as possible. Considering that it takes several tens of ms or more for mirror up and shutter control, the above time lag should be within several tens of ms. If it does not become a big problem.

Next, if the run-up of the holding member 7 is not completed, the process returns to step S31, and if it is completed, MCOM
An exposure start signal is output to 20 (step S33). Then, the subroutine image stabilization is executed again (step S3).
4). In this step S34, camera shake prevention control is performed so that the image moving speed that changes momentarily during exposure and the moving speed of the holding member 7 become equal. Subsequently, it is determined whether or not the image stabilization start signal is output from the MCOM 20, and while it is determined that the signal is not output, exposure is in progress, so step S34.
Then, the camera shake is prevented (step S35). When the signal is output, the holding member 7 is reset to the initial position (step S36). Here, the initial position means, for example, a position where the center position of the exposed surface of the film 4 coincides with the optical axis center. Then, the main routine of SCOM50 is complete | finished.

Next, the sequence of the above-mentioned subroutine "anti-vibration" will be described with reference to the flowchart of FIG. The angular velocity around the X axis is read (step S40). This is A /
The digital value of the output result of the D converter 68 is used. The digital value is, for example, decomposed into a range of 0V to 5V by 8 bits, and the output of the converter is 2.5V when the camera is stationary (80H in hexadecimal digital value), and the X-axis rotates clockwise. It is assumed that the voltage is 2.5 V or more when it is rotating and is 2.5 V or less when it is rotating counterclockwise on the X axis.

Similarly, the Y-axis rotational angular velocity is read from the output of the A / D converter 69 (step S41). Then, the X-axis direction image moving speed Vx and the Y-axis direction image moving speed V
y is calculated from equation (3) or equation (4) (steps S42 and S43).

Further, the holding member 7 for the X-axis direction and the Y-axis direction
Calculates the current speed of the vehicle (steps S44 and S4
5). This can be easily calculated from the pulse intervals of the PIs 52 and 53. That is, the interval (cycle) of one pulse is T
[S], and the number of slits of the disks 56 and 57 of PI is N, the motors 54 and 55 are 1 / (TN) [rps].
Therefore, when the distance that the holding member 7 moves when the motors 54 and 55 make one rotation is D [μm], the moving speed V ₇ of the holding member ₇ can be expressed by the following equation.

V ₇ = D / (T · N) [μm / s] (5) Since D and N are constant in the above equation (5), V ₇ is uniquely determined from T. Therefore, in order to shorten the calculation time, it is better to store the relationship between V ₇ and T in the ROM as a table and calculate V ₇ from the table without performing the calculation from the equation (5). Further, the current speed V of the holding member 7 in the X-axis direction
_7x and the current velocity in the Y-axis direction V _7y and Vx and V respectively
The magnitude of y is determined (steps S46 and S49).

If it is determined in step S46 that V _7x > Vx, the drive speed of the holding member 7 is decreased in step S47, and conversely, if V _7x <Vx is determined, the drive speed is increased (step S48). . Similarly, in step S49 described above.
If it is determined that V _7y > Vy in step S50, the drive speed of the holding member 7 is decreased, and conversely, if it is determined that V _7y <Vy, the drive speed is increased (step S51).

To change the driving speed of the holding member 7,
As described above, the outputs of the D / A converters 60 and 61 are changed to change the voltage applied to the motors 54 and 55. There is also a method of controlling the duty of turning on / off the transistors Q1 to Q8. Thus, the subroutine image stabilization is an important subroutine for controlling the image stabilization mechanism of the image stabilization camera of the present invention.

As described in detail above, according to the shake prevention cameras of the first and second embodiments, the entire film is integrally driven with the winding mechanism and the rewinding mechanism to prevent the camera shake. It is possible to obtain an anti-shake camera in which aberrations of the photographing optical system are not conspicuous even if the amount is increased, and it is not necessary to design an image stabilizing mechanism for each photographing optical system. Further, the anti-shake camera of the present invention using the magnetically recordable film can provide a smaller camera.

As described above, in the first and second embodiments, the camera shake is detected by driving the holding member for detecting the camera shake and holding the entire film including the cartridge in the direction of canceling the camera shake at the desired speed. It is characterized by

By the way, in the case of loading a cartridge into a camera using a magnetically recordable film, as shown in FIG.
As shown in (a) to (c), the camera exterior 200
Patrone-sized lid 20 provided on the side, bottom or part of the back of the
There is a technique in which a large back cover is not provided on the back surface of the camera, unlike a camera using a conventional film, by opening 1 and loading it. Here, FIG. 24 shows an example of a method of fixing the cartridge in a state in which the cartridge is loaded.

FIG. 24 shows a cross-sectional view of the CC 'plane with the lid closed in FIG. 23 (b). As shown in the figure, in this technique, a patrone presser 207 provided at the center of a lid 208 is movable in the vertical direction of the paper by the force of a spring 206, and when the lid 208 is closed, the patrone is pressed by the force of the spring 206. Is attached to the upper surface D of the cartridge main body 203 to fix the cartridge.

When the magnetically recordable film adopting such a patrone fixing method is adopted in the first and second embodiments, the patrone and the patrone chamber main body cancel the camera shake together with the holding member for holding the entire film. However, since the lid and the cartridge holder are immovable with respect to the exterior of the camera, there is a problem that the cartridge moves when the holding member is driven.

In the third embodiment described below, in view of such a problem, the patrone presser is not provided on the lid, but is provided on the holding member so that the patrone does not move even if camera shake is prevented. This is characterized in that the camera shake is detected and the holding member that holds the entire film including the cartridge is driven at a desired speed in the direction of canceling the camera shake to prevent the camera shake.

First, FIG. 19 shows the structure of a camera-shake preventing camera according to the third embodiment of the present invention. As shown in the figure, the magnetically recordable film 12 here refers to the entire film including not only the exposed surface of the film but also the cartridge, spool, and the like.

An X-axis direction drive unit 8 and a Y-axis direction drive unit 9 are provided as means for driving the holding member 7 in the X-axis and Y-axis directions, respectively. These mainly consist of drive mechanisms such as gears and actuators, and the actuators include, for example, DC motors, USMs, and piezoelectric elements.

On the other hand, in the camera shake detection unit 3, as described above, X
It is composed of an axial shake detection unit 3x and a Y-axis shake detection unit 3y, and includes an angular velocity sensor, an acceleration sensor, and the like. The camera shake amount detected by the camera shake detection unit 3 is input to the drive amount calculation unit 10. The drive amount calculation unit 10 calculates the drive amounts of the drive units 8 and 2 so that the current moving speed of the holding member 7 becomes the image moving speed of the hand shake to offset the hand shake. Control unit 11
Is a circuit for controlling the actuators of the drive units 8 and 9. With the above configuration, the camera shake of the photographer can be corrected.

Here, a detailed cartridge fixing method will be described with reference to FIG. A patrone presser 118 is provided on the holding member 7 so as to be rotatable around a pin 122, and is pulled by a spring 119 in the left-right direction on the paper surface. Since the cartridge 121 is pressed upward by the cartridge presser 118, the cartridge 121 can be fixed to the holding member 7. Reference numeral 108 is a shaft that drives a spool for feeding the film. In the figure, the patrone presser foot 118 is provided only in one place,
Of course, it may be provided in two or more places.

Next, another example of the cartridge fixing method will be described with reference to FIG. Unlike the example above,
Instead of a mechanical mechanism, a magnet is used to attract the metal portion of the cartridge 121 to fix the cartridge 121 to the holding member 7. In the figure, reference numerals 123 and 124 denote magnets, which are fixed to the holding member 7. Of course, the number of magnets need not be two.

As described above, according to the blur prevention camera of the third embodiment, the magnetically recordable film is used, and the film and the cartridge are fixed to the holding member and are integrally driven. It is possible to obtain a camera-shake preventing camera in which aberrations of the image-pickup optical system are not conspicuous even if the correction amount is increased and the camera-shake preventing mechanism does not need to be designed for each image-pickup optical system.
