Problems solved by technology
[0013] In the case of configuring the exterior parts of the lens barrel as described above, when, for example, from Figure 5 When the impact force in the directions of middle arrows F1 and F2 is applied to the front and side surfaces from above the cover of the lens barrel, the impact first deforms or breaks the cover member 112d itself, and then transmits the cover member 112d to the frame member 120 attached to it. , may cause deformation or damage of the frame member 120

Embodiment Construction
[0025] Hereinafter, the present invention will be described based on the illustrated embodiments.
[0026] Figure 1 ~ Figure 4 It is a figure which shows one embodiment of this invention. in, figure 1 It is an exploded perspective view showing the structure of the lens barrel of this embodiment. In addition, in figure 1 In Fig. 1 , an imaging unit arranged on the rear end side of the lens barrel but actually arranged inside the camera is also shown. figure 2 It is a sectional view along the optical axis of the lens barrel of this embodiment. In addition, in figure 2 The middle indicates a state where the lens barrel is set to the shortest focus position (wide-angle position) in the shooting standby state. image 3 It is an enlarged exploded perspective view of main parts showing the structure of the exterior member of the first group frame in the lens barrel of the present embodiment. Figure 4 It is an enlarged cross-sectional view of a main part showing a partial...

The present invention provides a camera and lens barrel with shock resistance and a lens barrel thereof. In the camera with the lens barrel, when overgreat impact from the outside is exerted to the front surface and side surface of lens barrel, the impact can be absorbed for restraining the deformation and dilapidation of externally installed component. Furthermore, the impact force which is transferred to the inner component from the externally installed component is reduced, and the adverse effect brought to the lens barrel by the impact force is restrained. The camera which is provided with the lens barrel (1) comprises the following components: a frame component (20) which forms the lens barrel; the externally installed component (12d) which covers the outer surface of frame component; and an impact absorbing component (56) which is configured between the frame component and the externally installed component.
Description
technical field [0001] The present invention relates to a camera and a lens barrel, and more specifically, to a lens barrel composed of a plurality of frame members for holding an optical lens group to move forward and backward in the direction of the optical axis, and a camera having the lens barrel , and more particularly, to the lens barrel and impact-resistant structures in the camera. Background technique [0002] Conventionally, a camera having a photo shooting function is usually configured so that a user can easily carry it for walking, and take it out for use when necessary. Therefore, when using or carrying the camera, the user may unintentionally collide the camera with other structural objects, or drop the camera on the ground due to handling errors or the like. [0003] On the other hand, among conventional cameras, a camera having a lens barrel having a structure in which a plurality of lens frames each holding a plurality of lens groups advances and retreats ...
