Feeder for feeding photosensitive material
First Claim
1. A feeder, incorporated into a photosensitive material processor of a printing device, for feeding a photosensitive material to the printing device, said feeder comprising:
- (a) a magazine body accommodating said photosensitive material therein and being formed with a take-out port for feeding out said photosensitive material;
(b) a pair of rollers, provided in said magazine body, for imparting a driving force while sezing a mid-portion of said photosensitive material;
(c) biasing means for separating one roller of said pair of rollers from the other roller of said pair of rollers; and
(d) driving force conveying means, partially exposed to the outside of said magazine body, for selectively displacing said one roller close to said other roller by applying pressing and rotational forces from outside of said magazine body to said pair of rollers, and for feeding out said photosensitive material from said take-out port by moving said photosensitive material while seizing said material, whereby said photosensitive material is totally stored in said magazine body before loading said magazine into said photosensitive material processor, thus preventing exposure of said photosensitive material to light to thus avoid the generation of unnecessary fogging in said photosensitive material.

Abstract
A magazine body accommodating a photosensitive material is loaded into a processor of a photo-printing device. The magazine body incorporates a pair of rollers for seizing a mid-portion of the photosensitive material, the rollers being separated from each other when feeding the material to the processor. When loading the magazine into the processor, the material is completely stored inside the magazine body. After loading the magazine, input rollers mounted on a light shielding cover of the processor are rotated while being pressed. At this time, the pair of rollers approach each other to seize the photosensitive material. Subsequently, the rollers rotate to feed the material to the processor.

17. A feeder, incorporated into a photosensitive material processor of a photo-printing device, for feeding a photosensitive material to this processor, said feeder comprising:
-
(a) a magazine body accommodating a rolled photosensitive material therein and being formed with a take-out port for drawing out the end of said photosensitive material led from said rolled photosensitive material; (b) shutters, provided at said take-out port, for shielding the inside of said magazine body at the time of closing, and for permitting passage of said photosensitive material at the time of opening, and (c) interlocking means, interposed between a light shielding cover of said processor and said shutters, for opening said shutters by a driving force, whereby said magazine storing all said photosensitive material, is loaded into said processor or dismounted therefrom while totally containing and shielding said photosensitive material from light, thus eliminating unnecessary fogging caused on said photosensitive material. - View Dependent Claims (18, 19)

20. A feeder, incorporated into a photosensitive material processor of a printing device, for feeding a photosensitive material to said printing device, said feeder comprising:
-
(a) a magazine accommodating said photosensitive material therein and being formed with a take-out port for feeding out said photosensitive material; (b) a pair of rollers, provided in said magazine body, for imparting a driving force while seizing a mid-portion of said photosensitive material; (c) biasing means for separating one roller of said pair of rollers from the other roller of said pair of rollers; (d) photosensitive material mid-portion seizing means, disposed between said rollers and a photosensitive material rolled portion, for holding said photosensitive material in a position suitable for a next feedout between said rollers even after releasing a photosensitive material seizing force of said rollers; and (e) driving force conveying means, partially exposed to the outside of said magazine body, for selectively displacing said one roller close to said other roller by applying pressing and rotational forces from the outside of said magazine body to said rollers and for feeding out said photosensitive material from said take-out port by moving said photosensitive material while seizing said material, whereby said photosensitive material is totally accommodated in said magazine body before loading said magazine into said photosensitive material processor, thus preventing exposure of said photosensitive material to light to thus avoid generation of unnecessary fogging of said photosensitive material. - View Dependent Claims (21, 22, 23, 24)
