Abstract
Abstract A device for feeding and positioning a recording medium as in a radiographic apparatus includes a grip member for gripping, feeding, and positioning the recording medium therein, the grip member being composed of a first plate, a second plate disposed in confronting relation to the first plate and openable at least in an upper end portion thereof with respect to the first plate, and a cover member disposed for closing and opening a gap between lower ends of the first and second plates. The device also includes positioning means for holding the grip member with at least its upper end portion opened in a recording medium receiving position, for displacing the grip member after it has received the recording medium and closing the upper end portion thereof thereby to position the grip member so as to position the recording medium in an exposure position in the grip member, and for displacing the grip member after the recording medium has been exposed thereby to open the cover member for discharging the exposed recording medium out of the grip member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
227 words
A device for feeding and positioning a recording medium, comprising: (a) a grip member for gripping, feeding, and positioning the recording medium therein, said grip member comprising a first plate and a second plate, each plate having upper and lower ends, means for mounting said second plate in confronting relation to said first plate with a gap between the lower ends of said plates and for permitting relative movement of at least the upper end of said second plate with respect to the upper end of said first plate to allow the recording medium to enter between said plates, and a cover member moveably mounted adjacent the lower ends of said plate for closing and opening said gap between lower ends of said first and second plates; and (b) positioning means for holding said grip member with the upper ends of said plates opened in a recording medium receiving position, means for displacing said grip member after it has received the recording medium and closing the upper end portion thereof to thereby position said grip member to position the recording meduim in an exposure position in said grip member and for further displacing said grip member after the recording medium has been exposed from said exposure position and for opening said cover member for discharging the exposed recording medium out of said grip member through said gap.
Claim 2
Independent Claim
227 words
A device for feeding and positioning a recording medium, comprising: (a) a grip member for gripping, feeding, and positioning the recording medium therein, said grip member comprising a first plate and a second plate, each plate having upper and lower ends, means for mounting said second plate in confronting relation to said first plate with a gap between the lower ends of said plates and for permitting relative movement of at least the upper end of said second plate with respect to the upper end of said first plate to allow the recording medium to enter between said plates, and a cover member moveably mounted adjacent the lower ends of said plate for closing and opening said gap between lower ends of said first and second plates; and (b) positioning means for holding said grip member with the upper ends of said plates opened in a recording medium receiving position, means for displacing said grip member after it has received the recording medium and closing the upper end portion thereof to thereby position said grip member to position the recording meduim in an exposure position in said grip member and for further displacing said grip member after the recording medium has been exposed from said exposure position and for opening said cover member for discharging the exposed recording medium out of said grip member through said gap.
Claim 3
Dependent Claim
45 words
A device according to claim 1, wherein said positioning means includes a pin member for opening said cover member, said pin member being positioned for abuttment against said cover member to open the cover member when said grip member is displaced from said exposure position.
Claim 4
Dependent Claim
38 words
A device according to claim 2, including a resilient member connected to said cover member for normally urging the cover member in a direction to close the gap between the lower ends of said first and second plates.
Claim 5
Dependent Claim
50 words
A device according to claim 1 or 3, wherein said first plate has an upper end portion mounted for rotation about a horizontal axis for displacement of said first plate between said recording medium receiving position and said exposure position by rotation about said upper end portion horizontal rotation axis.
Claim 6
Dependent Claim
53 words
A device according to claim 4, wherein said first and second plates are pivotably connected together at their lower ends, and said positioning means comprises a motor, and a crank mechanism operatively engaging said motor and connected to said second plate for displacing said second plate in response to rotation of said motor.
Claim 7
Dependent Claim
27 words
A device according to claim 5, further including a resilient member coupled to one of said plates for normally urging said one plate toward said exposure position.
Claim 8
Dependent Claim
23 words
A device according to claim 6, wherein said resilient member coupled to said one plate is also operably connected to said cover member.
Claim 9
Dependent Claim
54 words
A device according to claim 4, further including a resilient member coupled to one of said plates for normally urging said one plate toward said exposure position, and said positioning means comprises means for translating and angularly displacing said other plate while one plate is urged by said resilient member to said exposure position.
Claim 10
Dependent Claim
46 words
A device according to claim 8, wherein said second plate has a rod projecting from the lower end of said second plate, and said first plate has a guide member disposed at the lower end of said first plate and in sliding engagement with said rod.
Claim 11
Dependent Claim
36 words
A device according to claim 3, further including a resilient member coupled between said first and second plates for normally urging them toward each other and said positioning means comprising means for translating said grip member.
Claim 12
Dependent Claim
32 words
A device according to claim 10, including a guide member disposed between said first and second plates for engaging both side edge portions of the recording medium to guide the recording medium.
Claim 13
Dependent Claim
26 words
A device according to claim 1, wherein at least one of said plates has a recording medium confronting surface comprising a thin layer of foamed polyethylene.
Claim 14
Dependent Claim
17 words
A device according to claim 1, incorporated in a radiation image information recording and read out apparatus.
