Description

請求項４記載のカメラは、請求項３記載のカメラにおいて、保持鏡筒側に支持され、レンズ鏡筒を通じて撮像する撮像素子を備えているもので、撮像素子に対してレンズ鏡筒の合焦調整を一度行なえば、レンズ鏡筒と保持鏡筒とをばらして再び取り付ける場合でも、合焦関係を維持可能とする。 The camera according to claim 4 is the camera according to claim 3, which is provided with an imaging element that is supported on the holding barrel side and captures images through the lens barrel , and once the focusing adjustment of the lens barrel with respect to the imaging element is performed, the focusing relationship can be maintained even when the lens barrel and holding barrel are disassembled and then reattached.

請求項６記載のスコープは、請求項５記載のスコープにおいて、保持鏡筒側に支持され、レンズ鏡筒を通じて撮像する撮像素子を備えているもので、撮像素子に対してレンズ鏡筒の合焦調整を一度行なえば、レンズ鏡筒と保持鏡筒とをばらして再び取り付ける場合でも、合焦関係を維持可能とする。 The scope of claim 6 is the scope of claim 5, which is provided with an imaging element that is supported on the holding barrel side and takes images through the lens barrel , and once the focus of the lens barrel is adjusted relative to the imaging element, the focusing relationship can be maintained even when the lens barrel and holding barrel are disassembled and then reattached.

つまり、ＣＣＤカメラ11をカメラ筐体51に組み込む工程では、レンズ鏡筒21が保持鏡筒23に保持された状態では、カメラ筐体51のＣＣＤカメラ11の挿通孔52に基板46やレンズ押え環22がつかえてしまい組み込むことができないが、レンズ鏡筒21を保持鏡筒23から取り外した状態で、保持鏡筒23側をカメラ筐体51内に収容して固定し、レンズ鏡筒21をカメラ筐体51の外側から挿通孔52を通じて保持鏡筒23に螺合し、規制環24によりレンズ鏡筒21の保持鏡筒23への螺合量が規制されるまで螺合することにより、レンズ鏡筒21と保持鏡筒23とを所定の螺合量で、ＣＣＤカメラ11をカメラ筐体51に組み込むことができる。 In other words, in the process of assembling the CCD camera 11 into the camera housing 51, when the lens barrel 21 is held by the holding barrel 23, the circuit board 46 and lens retaining ring 22 get stuck in the insertion hole 52 of the CCD camera 11 in the camera housing 51, making it impossible to assembling the camera. However, when the lens barrel 21 is removed from the holding barrel 23, the holding barrel 23 side is housed and fixed inside the camera housing 51, and the lens barrel 21 is screwed into the holding barrel 23 from the outside of the camera housing 51 through the insertion hole 52 until the amount of screwing of the lens barrel 21 into the holding barrel 23 is restricted by the restriction ring 24, and the CCD camera 11 can be assembled into the camera housing 51 with the lens barrel 21 and holding barrel 23 screwed together by a predetermined amount.

請求項４記載のカメラによれば、請求項３記載のカメラの効果に加えて、保持鏡筒側にレンズ鏡筒を通じて撮像する撮像素子を備えるので、撮像素子に対してレンズ鏡筒の合焦調整を一度行なえば、レンズ鏡筒と保持鏡筒とをばらして再び取り付ける場合でも、合焦関係を維持できる。 According to the camera of claim 4, in addition to the effects of the camera of claim 3, an imaging element that takes an image through the lens barrel is provided on the holding barrel side, so once the focus of the lens barrel is adjusted relative to the imaging element, the focusing relationship can be maintained even when the lens barrel and holding barrel are disassembled and then reattached.

請求項６記載のスコープによれば、請求項５記載のスコープの効果に加えて、保持鏡筒側にレンズ鏡筒を通じて撮像する撮像素子を備えるので、撮像素子に対してレンズ鏡筒の合焦調整を一度行なえば、レンズ鏡筒と保持鏡筒とをばらして再び取り付ける場合でも、合焦関係を維持できる。 According to the scope of claim 6, in addition to the effect of the scope of claim 5, an imaging element that takes an image through the lens barrel is provided on the holding barrel side, so once the focus of the lens barrel is adjusted relative to the imaging element, the focusing relationship can be maintained even if the lens barrel and holding barrel are disassembled and then reattached.

Claims

a lens barrel having a male thread portion on its outer circumferential surface;
a holding barrel having a female thread portion on its inner circumferential surface into which a male thread portion of the lens barrel is threaded;
a restricting ring having an internal thread on its inner surface that screws into the external thread of the lens barrel, and that restricts the amount of threading between the lens barrel and the holding barrel by engaging with the holding barrel, thereby positioning and fixing the lens barrel.

2. The lens device according to claim 1, wherein the lens barrel and the restriction ring are fixed by adhesive.

3. A camera comprising the lens device according to claim 1.

4. The camera according to claim 3, further comprising an image pickup element supported on the holding barrel side and taking an image through the lens barrel .

A scope comprising the lens device according to claim 1 or 2.

6. The scope according to claim 5, further comprising an image pickup element supported on the holding barrel side and capturing an image through the lens barrel .
