Embodiment Construction

[0036] Such as Figure 1-Figure 14 As shown, a 6×7 frame curtain shutter camera with an electronic aperture drive device includes a body and a lens holder. The body adopts a Nissan Pentax camera body, and the lens adopts a German Rollei camera lens. In order to combine the two together, the lens mount connecting the two must be reprocessed and replaced. The lens mount is processed by titanium-aluminum alloy material, and the three connecting claws of the original lens mount are changed to four connecting claws, and the bayonet of the original lens mount is changed to a Rollei lens bayonet, which is connected to one end of the body through the original connection method , the other end of the lens holder is connected to the Rollei lens through 4 connecting claws; after that, 2 electronic contacts should be installed in the body, and the electronic drive device should be connected to maintain the electrical connection with the power supply, and at the same time ensure the drivin...

Abstract

The invention discloses a 6x7 frame curtain camera with an electric aperture driver, which comprises a body and a lens mount, wherein the body is mounted with an internal 6V battery and an external 7.4V battery. The invention is characterized in further composed of electric contactors I, II and trigger switches ST1, ST2 respectively mounted on a reflection plate and the bottom of a reflector box,wherein the electric contactors and trigger switches are electrically connected with an electric aperture driver and a power supply, the lens mount is provided with a lens bayonet with four connectingclaws, which one end near the body is fixed with the body port via a screw and another end is connected with the lens via the connecting claws, the lens is mounted with a drive motor electrically connected with the electric aperture driver. The invention combines the advantages of 6x7 frame body and the lens with good imaging ability, and combines the characters of electric aperture drive and theexchange property of different bodies and lens, to provide a new product for photograph.

Description

technical field [0001] The invention relates to a camera, in particular to a 6×7 frame curtain shutter camera with an electronic aperture driving device. Background technique [0002] At present, the lenses of most known professional cameras are detachable and replaceable, so as to meet the needs of shooting on different occasions. However, due to the inconsistent product standards of cameras produced by different manufacturers, the structure and shape of the lens holder bayonet are different, so that the goal of interchangeable lenses in different brands of cameras has not been realized. The fact that lenses are not interchangeable with different models of cameras prevents the advantages of lenses and cameras from complementing each other. That is to say, a lens with excellent imaging cannot be installed on a camera with an ideal format, and a camera with an excellent lens cannot take photos with an ideal format. This technical gap is still intensifying with the advanceme...
