Description

Negative scanning support

Technical Field

The utility model relates to the technical field of digital storage, in particular to a negative scanning support.

Background

The negative film widely used at present is to smear silver halide on an acetic acid film base, when light irradiates the silver halide, the silver halide is changed into black silver, and is fixed on the film base after a developing process, so that the negative film becomes a common black-and-white negative film, a color negative film is smeared with three layers of silver halide to express three primary colors, and a positive film, a primary imaging negative film and the like are also available besides the negative film.

For example, patent No. 200920206347.6 discloses a film scanner with continuous film feeding, which comprises a housing, a PCB support in the housing, a PCB board with a camera lens and a sensor fixed on the PCB support, and a backlight mechanism; the film clamp AB is matched with each other to form a film track groove, the knob penetrates through the upper cover of the shell, one end of the connecting rod is fixed to the knob, the other end of the connecting rod is inserted into a central hole of the rotary disc to be fixed, a film clamping tooth is arranged on the rotary disc, the film clamping tooth of the rotary disc penetrates through a notch of the film track groove at the A position of the film clamp, when a film is inserted into the film track groove, the tooth on the rotary disc is just sleeved into a square hole position on the film, and the rotary disc is driven to rotate by rotating the knob.
