A sectional view taken along the line A-A in the figure. FIG. 3 is a perspective view when the blind lid is opened by rotating the blind lid by about 180 degrees with respect to the lens. FIG. 4 is a perspective view of the blind lid folded in half from approximately the center compared to the state shown in FIG. 3. Figure 5 shows the folded blind lid from the state shown in Figure 4.
FIG. 3 is a perspective view when the blind lid is stored under the lens barrel after being rotated by 0°. FIG. 6 is an assembled perspective view of the blind lid for a lens according to the present invention, showing the blind lid in an open state. FIG. 7 is a cross-sectional view showing an example of a fixing part for closing the blind lid or fixing the blind lid folded in two.
FIG. 8 is a perspective view of the blind lid folded in half approximately at the center. FIG. 9 is a perspective view of the blind lid folded in half and rotated by about 90° relative to the ring compared to FIG. 8. FIG. 10 is a cross-sectional view of an example in which the joint provided on the ring and the rotary sliding portion of the blind lid are provided with protrusions so that they cannot easily rotate. FIG. 11 is a perspective view showing another embodiment for attaching the blind cover to the lens frame. FIG. 12 is a sectional view when the lens frame is sandwiched between the sandwiching parts. 1...Blind lid structure for lenses according to the present invention, 2...

Claims

[Claims for Utility Model Registration] 1. A device that captures images through a lens, which has a mounting base that can be attached to a lens frame, and a lens blind cover that can be freely opened and closed by an inversion support mechanism provided on the mounting base. When opened, the blind lid is approximately 18 mm from the lens.
A blind lid for lenses that can be inverted and held in the range of 0° to approximately 270°. 2 Claim No. 1 for Utility Model Registration, which is characterized in that the blind lid for a lens that can be opened and closed freely is characterized in that the blind lid has a joint part that can be bent or folded at one or more places when the blind lid is opened. Blind lid for lenses as described in section.
