Claims

[Scope of Claim for Utility Model Registration] 1. In a lens barrel having a movable distance setting member for moving the focusing lens group of the photographing lens to change the photographing distance, the image quality of the photographing lens satisfies a predetermined level. A regulating means for preventing the distance setting member from moving in the proximal direction is provided at a position on the proximate side beyond the closest distance determined as above, and when the distance setting member is further proximal beyond the closest distance determined as A lens barrel characterized in that when the lens barrel is located at a side position, it is possible to take pictures at a shooting distance shorter than the closest distance. 2. The lens barrel has a closest position display means for displaying when the distance setting member has been moved to a position corresponding to the closest distance. The lens barrel described in item 1. 3. The utility model registration request characterized in that the closest position display means has a click stop means that clicks to stop the movement when the distance setting member is moved to a position corresponding to the closest distance. Lens barrel according to scope 2. 4. The lens barrel is configured such that when the distance setting member covers a part of the normal photographing range from infinity to the closest distance,
The lens barrel according to any one of claims 1 to 3, characterized in that the lens barrel has a photographing range display means that displays a different display when moving through the close-up range. 5. The lens barrel according to claim 4, wherein the photographing range display means is configured to vary the operating force required to move the distance setting member in both of the ranges. . 6. The photographing range display means includes an electric switch whose connection state is switched depending on which of the two ranges the distance setting member is located, and is configured so that the display is switched by switching the connection of the electric switch. A lens barrel according to claim 4 of the utility model registration claim, characterized in that:
