(57) [Summary] (Corrected) [Purpose] To see an object behind the car from the front while sitting in the driver's seat. [Structure] A rear mirror composed of a convex lens, a prism, and a plane mirror is positioned such that an object behind the vehicle forms an image on the front mirror. It is attached to the rear of the car at an angle, and the front mirror, which is composed of a convex lens and a plane mirror, is attached to the front side position that is easier to see than the driver's seat. The rear image can be seen in the driver's seat as an erect image by two lenses and a prism.
Description
【考案の詳細な説明】 〔産業上の利用分野〕 各自動車又はトラクターなどに取りつけることができる。[Detailed Description of the Invention] [Industrial field of application] It can be mounted on each automobile or tractor.
バック見機によって自動車の後ろの様子を見てバックしやすくしようとするね らい。 We aim to make it easier to see the back of the car by using the back view machine.
バックの様子をとつレンズで受け、それを直角プリズムで、正立の像に変え、 平面鏡にうっし、運転席からバックのようすを見ようとするものである。 It takes a back view with a lens, converts it into an erect image with a right-angle prism, and then hangs on a plane mirror to see the back from the driver's seat.
〔作用〕後の様を凸レンズで倒立の像にし直角プリズムで倒立のまま直角にまげ 、それを前の方の凸レンズで正立にし、正立像を平面鏡で運転席で見る。[Function] Make an inverted image with a convex lens and bend it at an angle with a right-angle prism while keeping it upright with the convex lens in the front, make it upright, and see the upright image in the driver's seat with a plane mirror.
〔実施例〕凸レンズで倒立像を見ており潜水鑑などで直角プリズムで像を直角に まげて見ており、その像を、下の方にもって来て、正立の像を見ている。[Example] An inverted image is viewed with a convex lens, an image is bent at a right angle with a right-angle prism by a diving probe, and the image is brought to the lower side to see an upright image.
後の様子がよく見える。 You can see the situation afterwards.
