Abstract
A receptacle for radiographic film material comprising a first fluorescent screen disposed in a first path of movement extending around a first pair of rollers, and a second fluorescent screen disposed in a second path of movement extending around a second pair of rollers, the axes of all rollers being parallel to one another, and said two paths of movement being in part contiguous with each other, wherein at least one screen has a length shorter than the length of its path of movement, and that the screens are capable of being moved by a drive in one direction for receiving film material and in the opposite direction for delivering film material.
Claims3
A radiographic film transport for X-ray equipment which comprises:
- a first pair of parallelly-disposed rollers including a lead roller and a back roller;
- a second pair of parallelly-disposed rollers including a lead roller and a back roller, said lead rollers of said first and second pair of rollers cooperating to form a nip therebetween;
- a first fluorescent screen;
- a second fluorescent screen;
- a coupling member for linearly coupling one end of each of said first and second fluorescent screens;
- a first connecting means connecting the other end of said first fluorescent screen to said coupling member for coursing said first fluorescent screen including first connecting means about said first pair of parallelly-disposed rollers;
- a second connecting means connecting the other end of said second fluorescent screen to said coupling member for coursing said second fluorescent screen including second connecting means about said second pair of parallelly-disposed rollers;
- motive means for moving said first and second fluorescent screens about said first and second pair of parallelly-disposed rollers to cause said coupling member to move between said lead rollers and said back rollers thereby to permit the introduction of film material between said fluorescent screens when said coupling member moves in one direction and to deliver film material when said coupling member moves in an opposite direction.
