DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image blur correction device for correcting image blur due to camera shake in a camera or the like.

[0002]

2. Description of the Related Art An image blur correction apparatus is provided to correct a part of an optical system (a blur correction optical system) of a photographing optical system in a direction substantially perpendicular to an optical axis in order to correct an image blur caused by vibration of a camera during photographing. The optical axis of the photographing optical system is changed by moving the optical axis in two directions.

FIG. 8 is an assembly diagram showing an example of a conventional image blur correction device.

In FIG. 8, a correction lens group 1 is fixed to a pitching frame 2 movable in the Y direction. The pitching frame 2 is configured to be slidable with respect to a yawing frame 4 described later via pitching shafts 3a and 3b. The pitching frame 2 includes a coil 7p for an electromagnetic actuator and a light emitting element 12p for position detection.
Has been fixed.

Similarly, a coil 7y for an electromagnetic actuator and a light emitting element 12y for position detection are fixed to the yawing frame 4 movable in the X direction. The yawing frame 4 is fixed to the fixed frame 10 by a yawing shaft 5.
It is configured to be slidable via a and 5b. Here, it is necessary to supply current to the coil 7p provided on the pitching frame 2 sliding in the Y direction and the light emitting element 12p from a circuit provided outside the image blur correction device. A total of four terminals of the light emitting element 12p were connected using lead wires indicated by 23p and 24p or flexible printed cables.

Similarly, the yawing frame 4 sliding in the X direction
It is necessary to supply a current to the coil 7y provided in the device and the light emitting element 12y from a circuit provided outside the image blur correction device. Therefore, a total of four terminals of the coil 7y and the light emitting element 12y are connected to 23y and 24y. The connection was made by using a lead wire or a flexible printed cable shown in FIG.

[0007]

However, the conventional image blurring apparatus has the following problems.

(1) When lead wires are used for the wiring between the pitching frame 2 and the yawing frame 4 and the fixed frame 10, the number of assembly steps such as soldering increases, the cost increases, and the number of conductors also varies. Therefore, there is a high possibility that the wires will be broken during assembly.

(2) Even when a flexible printed cable is used, the reaction force exerted on the pitching frame 2 and the yawing frame 4 by the flexible printed cable differs depending on where one end is fixed to the fixed frame 10, and this reaction force is large. If so, the movement of the pitching frame 2 and the yawing frame 4 at the time of sliding deteriorates, so that the control characteristics are deteriorated and it is not possible to perform sufficient camera shake correction.

(3) When the pitching frame 2 slides in the Y direction, it is affected by the reaction force of only the flexible printed cables 23p and 24p fixed to the pitching frame 2.
However, when the yawing frame 4 slides in the X direction, it is not only affected by the reaction force of the flexible printed cables 23y and 24y fixed to the yawing frame 4, but also the flexible printed cable fixed to the pitching frame 2. Since 23p and 24p also move in the X direction at the same time, they are affected by the reaction force.

Therefore, in order to minimize the deterioration of the control characteristics of the yawing frame 4 as compared with the pitching frame 2, it is possible to reduce the influence of the reaction force from the flexible printed cables 23 and 24. There is a need to.

Therefore, in order to solve the above-mentioned conventional problems, an object of the present invention is to improve the assemblability by optimizing the configuration of a flexible printed cable fixed to a pitching frame, a yawing frame and a fixed frame. An object of the present invention is to provide an image blur correction device having sufficient control characteristics.

[0013]

In order to solve the above-mentioned problems, an image blur correction apparatus according to the present invention includes an image blur correction lens group, and a slide unit which holds the image blur correction lens group and slides in a first direction orthogonal to an optical axis. The first lens movable frame that is movable, the first electric component that is integrated with the first lens movable frame and serves as driving means and position detecting means for the first lens moving frame, and the first direction Differently, a second lens moving frame slidable in a second direction orthogonal to the optical axis, and a second lens moving frame driving unit and a position detecting unit integrated with the second lens moving frame. Two electrical components,
A fixed frame for holding the first and second lens moving frames; a first flexible printed cable electrically connected to the first electrical component; and a second flexible printed cable electrically connected to the second electrical component. The first and second flexible printed cables have one ends fixed to a fixed frame so as to be substantially parallel to the sliding direction of the first lens moving frame.

With this configuration, the influence of the reaction force generated by the flexure of the flexible printed cable can be minimized on both the yawing frame and the pitching frame, and the control characteristics can be prevented from deteriorating. As a result, it is possible to provide an excellent image blur correction device in which the degree of suppression of image blur is increased.

The light-receiving elements 14p and 14y in the figure are described with the distance from the light-emitting elements 12p and 12y larger than the actual one for easy understanding of the figure. Light emitting element 12
The light beams p and 12y project through the slits 13p and 13y, and the light passing through the slits 13p and 13y enters the light receiving elements 14p and 14y.

The operation of the thus-configured image blur correction device will be described below.

First, a camera shake acting on a camera having a built-in image blur correction device is detected by two angular velocity sensors 20 (not shown) arranged at 90 degrees. The output obtained by the angular velocity sensor is integrated over time. Then, it is converted into a camera shake angle, and is converted into target position information of the image blur correction lens group 1. In order to move the image blur correction lens group 1 according to this target drive position information, a servo circuit 21

As a result, it is possible to provide an excellent image blur correction device having a high degree of suppression of image blur.

In this embodiment, one ends 15a, 17a of the flexible printed cables 15, 17 are used.
The reinforcing plates 16 and 18 are attached to the
