Description of the Related Art As is well known, recent compact cameras and the like have a structure capable of selecting close-up, wide-angle, and telephoto shooting according to a photographer's request. If an auxiliary lens such as a conversion lens is inserted into the lens optical path by using a special drive motor for these special photographing operations, the cost of the product becomes high due to the use of the expensive drive motor.

（開閉部材）が用いられる。Therefore, conventionally, the shutter device with a lens driving mechanism shown in FIGS. 6 and 7 has a function of moving the focusing lens B in the direction of the lens optical axis α in association with the opening / closing movement of the shutter blade A. 6-11756. That is, in this shutter with lens drive, a reversible drive motor D for opening and closing the lens aperture C is also used for driving the focusing lens B. In this shutter device with lens drive mechanism, a pair of retainer springs E 1 , Open / close lever F held in neutral position by E 2
(Opening / closing member) is used.

レンズのレンズ開口Ｃが解放される。That is, the opening / closing lever F which is rotated in either forward or reverse directions about the central axis f by the eccentric pin d of the reversible drive motor D is linked to the shutter blade A for closing the lens opening C. Therefore, the lens aperture C of the photographing lens is released by either the forward or reverse rotational movement of the shutter blade A about the fulcrum axis a.

That is, since the driven pin g 1 of the interlocking lever G is engaged with the slot h 2 of the driven piece h 1 of the lens driving member H, the opening / closing lever F
When the interlocking lever G is rotated about the fulcrum axis g 2 in either forward or reverse direction, the lens driving member H is rotated in the opposite direction to the interlocking lever G, and the groove cam h of the lens driving member H is rotated. The focal lens B shown in FIG. 7 is moved in the direction parallel to the lens optical axis α by 3 or the helicoid, and the required focal length is obtained.

Since the focusing lens B is moved in the direction of the lens optical axis α, the driving torque of the lens driving member H is large,
It is necessary to use a large drive motor D, and there is a problem that the cost of the product increases due to the use of an expensive high torque motor. Further, according to this structure, since the focusing lens B constitutes a part of the photographing lens group, it is unavoidable to use the high-grade focusing lens B, but the focal length of the focusing lens B is fixed. Therefore, it is necessary to design an expensive focusing lens B according to the use, and there is a limit to cost reduction due to high mass production. An object of the present invention is to provide a lens-driving shutter having a lens member which has a small driving torque and can be manufactured relatively inexpensively and easily in view of the problems of the conventional lens-driving shutter as described above.

追従させる機能をもつ。The opening / closing lever 5 has a driving end portion 5b which is engaged with a driven pin 7b at the corresponding end of the interlocking lever 7 which is rotatable about a fulcrum shaft 7a. And
The fulcrum shaft 7a of the interlocking lever 7 supports the tip of an arm 8a of a transparent lens member 8 made of molded resin, and between the positioning pin 7c of the interlocking lever 7 and the positioning pin 8b of the arm 8a, An elastic holding spring 9 that determines the attitude of the arm 8a with respect to the interlocking lever 7 is applied, and a pair of stoppers 10A and 10B that determine the movable limit position of the arm 8a are arranged on both sides of the arm 8a. That is, the elastic holding spring 9 having the base portion fitted on the fulcrum shaft 7a causes the lens member 8 to follow the rotational movement of the interlocking lever 7 as long as no external force acts on the lens member 8. When any of the stoppers 10A and 10B comes into contact with 8a, the lens member 8 is stopped at the same rotational position, and at the same time, the interlocking lever 7 follows the rotational movement of the opening / closing lever 5 regardless of the stop of the lens member 8. It has a function to

The short-focus lens 8c and the long-focus lens 8d shown in FIG. 4 are provided at positions where the lens optical path including the movement path is a movement locus, and the short-focus lens 8c includes the right-side stopper 1 as shown in FIG.
At a position where the arm 8a hits 0B, the object image of the taking lens is formed on the surface X of the photoconductor by intervening in the optical path of the lens. Further, although the long-focus lens 8d intervenes in the lens optical path to form a subject image on the photoconductor surface X at the position where the arm 8a hits the left stopper 10A, the lens member 8 is shown in FIG. When in the shown neutral position, the bifocal lens 8c and the bifocal lens 8

きる。FIG. 5 is a view corresponding to FIG. 4 of another embodiment of the present invention. This lens member 8 is selected for the lens optical path described above, instead of the short focus lens 8c and the far focus lens 8d. It is provided with a circular hole 8e and a converter lens 8f which can intervene with each other. At this time, the converter lens may be a long focus (telephoto) system teleconverter lens, or a short focus (wide angle) system wide converter or various lenses capable of obtaining a special expression.
In other words, the camera is a camera capable of selecting shooting at a standard distance / angle of view and shooting at a distance other than the standard distance / angle of view in this embodiment, and has a structure suitable for a camera or lens-fitted film in which low cost is prioritized. However, as can be understood from this example, the shutter device with the lens driving mechanism of the present invention can easily cope with the specification change only by replacing the lens member.

する。Since the shutter device with the lens driving mechanism according to the illustrated embodiment has the above-described structure, the exposure operation is performed as follows in the mode selected by the photographer. That is, when the release is performed by the photographer, the drive motor 2 is activated in the direction of the arrow in FIG. 1 or in the direction opposite to this arrow according to the selected mode. Therefore, in the case of rotation in the direction of the arrow, the opening / closing lever 5 rotates clockwise about the central axis 5a by the eccentric pin 3, but the interlocking lever 7 rotates the fulcrum shaft according to the rotating movement of the opening / closing lever 5. It rotates counterclockwise around 7a, and this rotational movement is transmitted to the arm 8a of the lens member 8, and the short focus lens 8c intervenes in the lens optical path of the taking lens to complete the preparation for telephoto shooting.

了する。Thereafter, by the subsequent rotational movement of the drive motor 2 in the direction of the arrow, the shutter blade 6 is rotated counterclockwise about the fulcrum pin 6b via the opening / closing lever 5.
As shown in FIG. 2, the lens opening 1 is released for a predetermined time, and the photosensitive member surface X is exposed. When the release of the shutter blades 6 is completed, the drive motor 2 is rotated in the reverse direction, each member is returned to the position shown in FIG. 1, and the exposure operation is completed.
