In the lens barrel associated with the present invention, the hammer portion is preferably layered and disposed on the widest surface of the faces constituting the casing. There is a case where the wall resonance of the widest surface of the surface constituting the casing is large. However, since the bell portion is provided on the surface, the resonance of the casing when the drive motor is operated can be reliably prevented. Further, since the weight portion is provided in a layered manner on the widest surface of the surface constituting the casing, the lens barrel can be made thinner in a direction substantially perpendicular to the surface. The photographing apparatus according to the present invention includes the above-described lens barrel and an imaging element that detects light imaged by the lens. According to this imaging apparatus, since the above-described lens barrel is provided, it is possible to prevent the resonance of the casing when the driving motor is operated. According to the present invention, the resonance of the casing when the drive motor is operated can be reliably prevented.

As shown in FIGS. 2 and 3, the driving unit 17 is disposed such that the standing direction of the support portions 18b and 18c coincides with the direction of the shank, and is disposed in the north of the opening of the main body portion 5, and the mounting portion 18a is screwed to the main body portion 5. The wall is attached to the body portion 5. Thus, in the drive unit 17, the stepping motor 21 and the stepping motor 24 are disposed differently from each other, so that the lead screw 22 and the lead screw can be approached. Thereby, the driving unit 17 contributes to the reduction in thickness of the main body portion 5 or the lens barrel 2. The convex portion 23& of the driven nut 23 screwed to the lead screw 22 is fitted into the concave portion of the engaging portion 12c of the shutter-focus lens unit 12. Thereby, when the stepping motor 21 rotates the lead screw 22, the shutter/lens lens unit 12 moves with the optical axis L2. On the other hand, the convex portion 26a of the driven nut 7 M354082 26 screwed to the lead screw 25 is fitted to the concave portion of the engaging portion 13c of the zoom/focus lens unit 13. Thus, when the lead screw is rotated by the stepping motor 24, the focus-focus lens unit 13 moves along the optical axis L2. A circuit board 27 is mounted on the lid portion 6 of the body 4, and the circuit board 27 5 is provided on the inner surface with an image sensor 3 positioned on the rear side of the fixed lens unit on the optical axis L2. Further, a shutter drive circuit, a motor drive circuit or the like is provided on the inner surface of the circuit board 27, and a connector port 28 for inputting an output electric signal to the circuit board 27 is provided on the outer surface of the circuit board 27.

Shutter/Shutter The shutter and shutter drive circuit of the lens unit 12 is electrically connected by the FPC 32 and the fPC3. The FPC 32 extends to the outside of the side wall of the body portion 5 opposite to the opening 5b, and the FPC 31 is electrically connected to the FPC 32. 15 The drive unit 17 disposed in the opening 5b of the main body portion 5 and the FPC3 disposed outside the side wall of the main body portion 5 opposite to the opening portion 5a are covered by the exterior cover 33, and the outer cover 33 is transmitted through stainless steel The formed thin plate is bent in an L shape and integrally formed. Further, the FPC 3 1 disposed on the outer surface of the side wall of the main body portion 5 facing the opening portion 5b and the 20 circuit substrate 27 attached to the lid portion 6 of the casing 4 are covered by the exterior cover 34, and the exterior cover 34 is permeable. The thin plate made of unrecorded steel is bent into an L shape and integrally formed. The exterior cover 33 and the exterior cover 34 are detachably engaged with the corner portion of the main body portion 5 that faces the opening portion 5a and the side wall that faces the opening portion 5b. The opening portion 5a and the opening portion in the body portion 5 are detachably engaged. The corners sandwiched by 5b are locked to the cover portion 6 of the 8 M354082 housing 4. Further, the exterior cover 34 is electrically connected to the circuit board grounding terminal, and the exterior covers 33, 34 are electrically connected to a metal film formed on the outer surface and the inner surface of the front surface of the body portion 5 such as a vapor.

Further, a portion corresponding to the connector port 28 of the circuit board 27 is cut at the outer cover % t and can be connected to the connector with respect to the connector port 28 . Further, as shown in FIG. 1, in the outermost surface (here, the plane) of the surface constituting the casing 4, that is, the outer surface of the front wall of the main body portion 5, a rectangular shape composed of, for example, no steel is bonded by a double-sided tape. Thin plate-shaped hammer. That is, the bell portion is provided on the outer surface of the front wall of the main body portion 5. Further, the front wall of the main body portion 5: the hammer portion 35 is a resonance in the casing 4 when the stepping motors 21 and 24 are operated. The lens barrel 2 and the imaging device are described above. The stepping motor 21 is used as a resonance portion knife and a front wall of the body portion 5 in the case of the case. Thereby, the number of natural vibrations of the casing 4 changes. Therefore, it is possible to reliably prevent the casing (4) during the operation of each of the stepping motors 21, 24 from resonating. Further, since the weight portion 35 is layered in the widest surface of the surface constituting the casing 4: the outer surface of the surface of the body portion 5, the ancient A buckle substantially orthogonal to the outer surface of the front wall of the body portion 5 is provided. The thickness of the lens barrel 2 or the photographing apparatus 1 can be reduced in a direction containing two directions of soil and direction. The hammer portion 35 can also be used as the display panel with the serial number or the like attached to the hammer P35. The creation is not limited to the above embodiment. I, such as Hammer #35, is not limited to a rectangular thin plate-shaped 20 M354082 member made of unrecorded steel, and can be formed into various shapes by various materials. Further, the hammer core is not limited to being formed separately from the casing 4, and the thickness of a predetermined portion of the thickened casing 4 may be integrally formed with the casing 4. X ' Further, each of the stepping motors 21 and 24 is not limited to the case where the support member is "directly attached to the casing 4", and may be directly attached to the casing 4.
