Can be prevented. 2. Description of the Related Art A lens barrel having a lens attached thereto is mounted on a lens barrel support member via a rotary motion-thrust motion conversion mechanism, and a motor is provided on an outer peripheral portion of the lens barrel. A focusing device for a camera in which the lens barrel is moved in the thrust direction by relatively rotating the lens barrel support member and the lens barrel support member to focus the lens is known from Japanese Utility Model Laid-Open Publication No. 56-14713. The focusing device (automatic focus adjustment mechanism) of this camera is the fifth
As shown in the figure, the lens barrel 41 to which the photographing lens 34 is attached,
The rotation is performed via a rotation-thrust motion conversion mechanism 50 including a cam groove 40 provided on the outer peripheral surface of the lens barrel 41 and a cam locking pin 39 provided on a rotating ring 42 disposed on the outer circumference of the lens barrel 41. Attached to the ring 42, a rotor 35 and a stator 36 of a stepping motor are arranged on the outer periphery of the rotating ring 42, and by rotating the rotating ring 42 with the stepping motor, the lens barrel 41 is moved in the thrust direction. , The focal length of the taking lens 34 is adjusted. Reference numeral 38 denotes a bearing that rotatably mounts the rotating ring 42 on the outer case member 44, and reference numeral 46 denotes a rotation stopping pin for preventing rotation of the lens barrel 41. The focusing device disclosed in Japanese Utility Model Publication No. 56-14713. As described above, by arranging a motor on the outer periphery of the lens barrel 41 to the rotating ring 42, the size of the apparatus can be reduced and the power consumption can be reduced. [Problems to be Solved by the Invention] By the way, in the conventional focusing device, as described above, the rotary motion-thrust motion conversion mechanism 50 is provided with the inclined cam groove 40 provided on the outer peripheral surface of the lens barrel 41. And a cam engaging pin 39 provided on the rotating ring 42, the tip of the cam engaging pin 39 is fitted into the cam groove 40, and the lens barrel 41 is rotated by rotating the rotating ring 42. Due to the configuration of moving in the thrust direction, a backlash (play) occurs between the lens barrel 41 and the rotating ring 42, so-called rattling occurs,
There is a problem that it adversely affects the focusing performance. This is because, in order to rotate the rotary ring 42 smoothly, it is indispensable to provide an appropriate backlash (play) between the cam engaging pin 39 and the cam groove 40. SUMMARY OF THE INVENTION The present invention has been made to provide a focusing device for a camera, which can eliminate rattling between a lens barrel and a lens barrel supporting member and an adverse effect on focusing performance, which are caused by the above-mentioned backlash. is there. [Means for Solving the Problems] A rotor yoke and a rotor magnet constituting a rotor of a stepping motor for driving the lens barrel are mounted on the outer circumference of the lens barrel on which the lens is mounted, and an appropriate gap is provided on the outer circumference of the rotor magnet. In addition, a stator of the step motor is disposed, the stator is fixed to a stator base by a stator housing, and a rotational movement is made between an inner peripheral surface of a lens barrel receiving portion of the stator base and an outer peripheral surface of the lens barrel. -A ring-shaped magnet and a yoke for applying a thrust-direction moving force to the lens barrel are attached to opposing surfaces of the rotor yoke and the stator housing while interposing a thrust motion conversion mechanism. [Operation] The lens barrel and the lens barrel support member relatively move in the thrust direction due to a suction force or a repulsive force generated between the magnet and the yoke, thereby eliminating rattling due to the backlash of the rotary motion-thrust motion conversion mechanism. I do. Embodiment Next, the present invention will be described with reference to FIGS. Reference numeral 1 denotes a focusing device for a camera according to the present invention. This focusing device 1
Is a PM for driving the lens barrel on the outer circumference of the lens barrel 3 to which the lens 2 is attached.
The stator 6 of the step motor 4 is disposed with the rotor 5 of the mold step motor 4 fixed and the outer periphery of the rotor 5 with an appropriate gap δ.
Is fixed to the stator base 8 by the stator housing 7, and the lens barrel 3 is rotated and rotated by the rotation-thrust motion conversion mechanism 10 composed of male and female screws on the lens barrel receiving portion 9 of the stator base 8. It is mounted movably in the thrust direction. That is, the relative rotational motion between the lens barrel 3 and the stator base 8 as the lens barrel support member is converted into thrust motion. The rotor 5 has a rotor yoke 5a.
And a rotor magnet 5b. The stator 6 has an A-phase pole tooth yoke 6a and a B-phase pole tooth yoke 6b.
The rotor 5 includes an A-phase coil 6c and a B-phase coil 6d provided in A- and B-phase pole tooth yokes 6a and 6b, respectively.
(Strictly speaking, the rotor magnet 5b) The length l 1 is the stator 6
(Strictly A, B Aikyokuha yoke 6a, 6b) are formed also by the amount of movement of the thrust direction of the lens barrel 3 longer than the length l 2 of the. The stepping motor 4 is constituted by a driving circuit as shown in FIG. 3, and by applying a pulse signal as shown in the flowchart of the sequence of FIG. 4 to the driving circuit, the mirror is controlled in accordance with the number of pulse signals. The torso 3 is rotated by a predetermined angle. Reference numerals 11 and 12 denote a magnet and a yoke which apply a moving force in the thrust direction between the lens barrel 3 and the stator base 8 which is a lens barrel support member. In the embodiment, the magnet 11
Is formed in a ring shape, and is attached to one end of the rotor 5 (strictly, a rotor yoke 5a).
Numeral 12 is attached to the bent portion 7a of the stator housing 7, and the magnet 11 and the yoke 12 are arranged at a predetermined distance d.
And a suction force in the thrust direction is generated therebetween. The focusing device of the camera according to the embodiment has the above-described configuration, and applies a suction force in the thrust direction between the lens barrel 3 and the stator base 8 as the lens barrel support member by the magnet 11 and the yoke 12. Therefore, the lens barrel 3 and the stator base 8 are attracted to each other and joined together, and the lens barrel 3 and the stator base 8 are connected to each other in a state where the backlash of the rotary motion-thrust motion conversion mechanism 10 composed of male and female screws is lost. This prevents rattling between the two, and enables a smoother focusing action and a more accurate focusing property to be obtained. The ring-shaped magnet 11 is magnetized in the circumferential direction to the number of poles which is an integral multiple of the number of poles of the rotor magnet 5b, and is mounted in the same phase as the rotor magnet 5b, and the ring-shaped magnet 11 and the yoke are attached. By providing a sensor (not shown) such as a Hall IC or a Hall element between the positions 12, positioning can be performed in a so-called open loop, so that the autofocus system can be simplified. Also, the magnet 11 is attached to the stator base 8 side, and the yoke is
The magnet 12 and the yoke 12 may be those that generate a repulsive force in the thrust direction instead of the suction force. Further, in the embodiment, the case where the rotary motion-thrust motion converting mechanism 10 is constituted by male and female screws is shown, but the rotary motion-thrust motion converting mechanism 10 is constituted by a cam groove and a cam locking pin as shown in FIG. May be. [Effects of the Invention] As described above, the present invention relates to a ring-shaped magnet which attracts or repels a lens barrel and a stator base as a lens barrel support member to impart a thrust moving force to the lens barrel. Since the yoke is provided, the stator base and the lens barrel are not decentered with respect to the stator base, and the rotational motion-thrust motion converting mechanism interposed between the stator base and the lens barrel causes a backlash. And the like, which can prevent the backlash during movement, smoothen the focusing operation, and improve the focusing performance. Further, since the rotor yoke and the stator housing are provided with a function as a magnet and yoke holder for imparting a thrust moving force to the lens barrel, assembly of these magnets and the yoke can be performed easily and easily.
