no. 1 Embodiment approach ）

[0030] In this embodiment mode, the present invention is applied to imaging devices generally called electronic cameras, digital cameras, and the like. The imaging device 1 of the present embodiment is configured to have a lens frame 20 inside, and the lens frame 20 holds imaging optical system components such as a lens for forming a subject image and an imaging element disposed on an imaging surface of the imaging optical system components. 46. In addition, the imaging element 46 is an image sensor such as a CCD or a CMOS sensor.

[0031] The imaging optical system components include a prism 50 and have a so-called optical path reflective type called a folding optical system or a bending optical system in which the optical axis is bent by the prism 50 . In the imaging device 1 of the present embodiment, the light incident from the side (front) of the imaging device 1 facing the subject is bent by 90 degrees by the prism 50, which is a so-called right-angle prism, and the lig...

no. 2 Embodiment approach ）

[0067] Next, a second embodiment of the present invention will be described. This embodiment differs from the first embodiment only in the form of the holding plate and the engaging portion. Therefore, only the differences from the first embodiment will be described below, and the same reference numerals will be attached to the same components as those in the first embodiment, and descriptions thereof will be appropriately omitted.

[0068] In the above-mentioned first embodiment, the engaging portion 10 provided on the frame member 2 has a form of sandwiching the holding plate 31 in the vertical direction, but the engaging portion 10 is not limited to this first embodiment. Such as Figure 11 As shown, in the present embodiment, as an example, the holding plate 31 has a notch 31 d that is a through hole. Furthermore, the engaging portion 10 has a shape protruding rearward from the frame member 2 and fitting into the notch portion 31 .

[0069] If it is a form in which the ...

[0071] Next, a third embodiment of the present invention will be described. This embodiment differs from the first embodiment only in the form of the holding plate and the engaging portion. Therefore, only the differences from the first embodiment will be described below, and the same reference numerals will be attached to the same components as those in the first embodiment, and descriptions thereof will be appropriately omitted.

[0072] In the above-described embodiment, the holding plate 31 has the curved portion 31c and has an L-shape when viewed from the vertical direction, but the holding plate 31 is not limited to this form. Such as Figure 12 As shown, in this embodiment, as an example, the holding plate 31 has a flat plate shape without a curved portion, and the other end portion 31b also protrudes further forward of the front surface 20b of the lens frame 20 .

[0073] On the other hand, the engaging portion 15 provided on the frame member 2 is a substantially lin...

Abstract

The invention provides a pick-up device which keeps a lens frame by a buffer part and is thin. The pick-up device has a shooting optical system part which uses a prism to bend an optical axis. The pick-up device has a frame part, an optical system part, the lens frame and the buffer part, wherein the optical system part comprises a prism which bends a first optical axis by 90 degrees as a second optical axis for outgoing to enable a target to be imaged, the lens frame keeps the optical system part, and the buffer part is arranged between the frame part and the lens frame. The lens frame is elastically supported on the frame part, the buffer part is fixed between one or two side surfaces of the lens frame toward a vertical direction of the first optical axis and the second optical axis and one or two maintain plates on the frame part and opposite to the side surfaces.

Description

technical field [0001] The present invention relates to an imaging device having a lens frame holding an imaging optical system component including a prism. Background technique [0002] As an imaging device that captures a still image or a moving image of a subject, for example, Japanese Patent Application Laid-Open No. 2010-177964 discloses an imaging device in which a prism is arranged in an imaging optical system member to bend an optical axis. In the imaging device disclosed in Japanese Patent Application Laid-Open No. 2010-177964, the first optical axis incident from the subject is bent by 90 degrees to the second optical axis by a rectangular prism disposed on the object side of the imaging optical system member. , the thickness of the imaging device can be reduced. In the imaging device disclosed in Japanese Patent Application Laid-Open No. 2010-177964, a driving mechanism such as an imaging optical system component including a rectangular prism and an electric moto...
