Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
191 words
A radiation image recording apparatus comprising a sheet feed body fitting section (4) which releasably holds a sheet feed body (3) containing stimulable phosphor sheets or a continuous stimulable phosphor sheet (2) used for the radiation image recording and reproduction or a sheet feeding section containing said stimulable phosphor sheets or a continuous stimulable phosphor sheet (2), a stimulable phosphor sheet holding means for supplying each said stimulable phosphor sheet or predetermined lengths of said continuous stimulable phosphor sheet (2) from said fitted sheet feed body (3) or said sheet feeding section to a recording position (10), and a sheet delivery means for ejecting said stimulable phosphor sheet from said recording position (10) after a radiation image is recorded on said stimulable phosphor sheet (2) and for delivering it to a sheet receiving section (6) or a radiation image information read out and reproducing system (28), characterized in that an irradiation means (20) is provided between said sheet feed body fitting section (4) or said sheet feeding section and said stimulable phosphor sheet holding means, which irradiation means (20) is used to erase the noise in said stimulable phosphor sheet (2).
Claim 2
Dependent Claim
191 words
A radiation image recording apparatus comprising a sheet feed body fitting section (4) which releasably holds a sheet feed body (3) containing stimulable phosphor sheets or a continuous stimulable phosphor sheet (2) used for the radiation image recording and reproduction or a sheet feeding section containing said stimulable phosphor sheets or a continuous stimulable phosphor sheet (2), a stimulable phosphor sheet holding means for supplying each said stimulable phosphor sheet or predetermined lengths of said continuous stimulable phosphor sheet (2) from said fitted sheet feed body (3) or said sheet feeding section to a recording position (10), and a sheet delivery means for ejecting said stimulable phosphor sheet from said recording position (10) after a radiation image is recorded on said stimulable phosphor sheet (2) and for delivering it to a sheet receiving section (6) or a radiation image information read out and reproducing system (28), characterized in that an irradiation means (20) is provided between said sheet feed body fitting section (4) or said sheet feeding section and said stimulable phosphor sheet holding means, which irradiation means (20) is used to erase the noise in said stimulable phosphor sheet (2).
Claim 3
Dependent Claim
22 words
The apparatus as defined in Claim 1 wherein said irradiation means (20) has an exposure amount ranging from 3,000 to 100,000 lx.s.
Claim 4
Dependent Claim
22 words
The apparatus as defined in Claim 1 wherein said irradiation means (20) has an exposure amount ranging from 15,000 to 30,000 Ix.s.
Claim 5
Dependent Claim
41 words
The apparatus as defined in Claim 1 further comprising a means for carrying said stimulable phosphor sheets at a predetermined speed from said sheet feed body fitting section (4) or said sheet feeding section to said stimulable phosphor sheet holding means.
Claim 6
Dependent Claim
35 words
The apparatus as defined in Claim 4 further comprising a guiding means for guiding said stimulable phosphor sheets from said sheet feed body fitting section (4) or said sheet feeding section to said carrying means.
Claim 7
Dependent Claim
32 words
The apparatus as defined in Claim 4 or 5 further comprising a means which controls the carrying speed of said carrying means with respect to the power of said irradiation means (20).
Claim 8
Dependent Claim
36 words
The apparatus as defined in Claim 1 further comprising a means for taking up said stimulable phosphor sheets (2) one at a time from said sheet feed body fitting section (4) or said sheet feeding section.
Claim 9
Dependent Claim
40 words
The apparatus as defined in Claim 1 further comprising a supporting means for guiding and supporting said stimulable phosphor sheets (2) between said sheet feed body fitting section (4) or said sheet feeding section and said phosphor sheet holding means.
Claim 10
Dependent Claim
28 words
The apparatus as defined in Claim 8 wherein said supporting means consists of a pair of plates (21 a, 21 b) one (21 b) of which is transparent.
Claim 11
Dependent Claim
32 words
The apparatus as defined in Claim 9 wherein said transparent plate (21 b) of said pair of plates is positioned on the side nearer to said irradiation means (20) than the other.
Claim 12
Dependent Claim
28 words
The apparatus as defined in Claim 8 further comprising a stopper means (22) for holding said stimulable phosphor sheets (2) in a predetermined position at said supporting means.
Claim 13
Dependent Claim
32 words
The apparatus as defined in Claim 1 wherein said stimulable phosphor sheet (2) is in the form of a continuous sheet and the holding means also serves as said sheet delivery means.
