Embodiment Construction

[0028] [External structure of imaging device]

[0029] Figures 1 to 6 The external structure of the imaging device 10 according to the first embodiment of the present invention is shown. More specifically, Figures 1 to 6 The front, rear, top, bottom, left and right sides of the imaging device 10 are shown, respectively. The imaging device 10 is detachably mounted with an interchangeable lens (shooting lens) 2, in this case, in Figure 7 A perspective view of a camera system (imaging system) 1 in which an interchangeable lens 2 is mounted on an imaging device 10 is shown in . The illustrated camera system 1 is used, for example, as a single-lens reflex digital camera.

[0030] see figure 1 , the imaging device 10 has on its front side: a mounting unit 301 to which the interchangeable lens 2 is attached approximately in the center of the front side; a lens interchange button 302 arranged on the right side of the mounting unit 301; The grip portion 303 is provided in a pr...

Abstract

The present invention relates to an imaging device on which an interchangeable lens is detachably mounted, the imaging device comprising: a mounting unit on which the interchangeable lens is attached. In the imaging device, the mounting unit is provided at its periphery with a colored area having a specific color along the outer edge of the mounting unit, and regarding the interchangeable lens conforming to the A specific interchangeable lens of a predetermined requirement of adaptability of an imaging device, the mounting unit of the specific interchangeable lens connected to the mounting unit of the imaging device is provided with a colored area on its periphery, the colored area along An outer edge of the mounting unit surrounding the specific interchangeable lens has the same color as the specific color.

Description

technical field [0001] The present invention relates to a technique used on an imaging device detachably mounted with an interchangeable lens. Background technique [0002] In a lens-interchangeable camera system (imaging system) such as a single-lens reflex camera, there are cases where improperly placed interchangeable lenses, such as those whose back focus distance is different from that of the camera The subject (of the mirror distance) does not fit. [0003] As to prevent these types of inappropriate interchangeable lenses from being misplaced, some techniques have been given which allow the physical placement of the inappropriate interchangeable lenses by changing the shape of the mounting unit according to the back focus distance. Type lenses become unfeasible. See Japanese Patent Application Laid-Open No. 2005-70711 (Patent Document 1) and Japanese Patent Application Laid-Open No. 2005-70712 (Patent Document 2). Contents of the invention [0004] However, the te...
