Abstract
Abstract A recording apparatus for use with a radiation-sensitive member includes a holder for holding the radiation-sensitive member, an image forming system for applying a radiation energy, having a pattern of distribution, to the radiation-sensitive member to form an image thereon, a vibration meter for measuring vibration to detect relative movement between the radiation-sensitive member and the pattern of the radiation energy to be applied to the radiation-sensitive member, and a discriminating circuit for discriminating, on the basis of the output from the vibration meter, whether the image forming system is to be actuated, whereby any positional deviation of or any distortion in the image is mitigated.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
94 words
An apparatus for use with a radiation-sensitive member, comprising: means for holding the radiation-sensitive member; image forming means for applying radiation energy having a distribution pattern to the radiation-sensitive member to form an image thereon; vibration detecting means for detecting relative vibratory movement between the radiation-sensitive member and the distribution pattern of the radiation energy to be applied to the radiation-sensitive member, said detecting means producing a detection signal; and means for discriminating, on the basis of the detection signal supplied from said detecting means, whether said image forming means is to be actuated.
Claim 2
Independent Claim
94 words
An apparatus for use with a radiation-sensitive member, comprising: means for holding the radiation-sensitive member; image forming means for applying radiation energy having a distribution pattern to the radiation-sensitive member to form an image thereon; vibration detecting means for detecting relative vibratory movement between the radiation-sensitive member and the distribution pattern of the radiation energy to be applied to the radiation-sensitive member, said detecting means producing a detection signal; and means for discriminating, on the basis of the detection signal supplied from said detecting means, whether said image forming means is to be actuated.
Claim 3
Dependent Claim
22 words
An apparatus according to claim 1, wherein said vibration detecting means detects vibration in three directions in a three-dimensional rectangular co-ordinate system.
Claim 4
Dependent Claim
14 words
An apparatus according to claim 1, wherein said vibration detecting means comprises an accelerometer.
Claim 5
Dependent Claim
15 words
An apparatus according to claim 1, wherein said vibration detecting means comprises a laser interferometer.
Claim 6
Dependent Claim
19 words
An apparatus according to claim 1, wherein said vibration detecting means is connected to said radiation-sensitive member holding means.
Claim 7
Dependent Claim
60 words
An apparatus according to claim 5, wherein said radiation-sensitive member holding means is movable in orthogonal directions, wherein said vibration detecting means detects vibration in three directions in a three-dimensional rectangular coordinate system and wherein at least one of the three-directions in the three-dimensional rectangular coordinate system coincides with one of the moving directions of said radiation-sensitive member holding means.
Claim 8
Dependent Claim
85 words
An apparatus according to claim 1, wherein said vibration detecting means comprises a first vibration detecting means connected to said radiation-sensitive member holding means to detect vibration with respect thereto and a second vibration detecting means connected to said image forming means to detect vibration with respect thereto, and wherein said discriminating means produces an operation command signal to actuate said image forming means on the basis of at least the outputs from said first and second vibration detecting means and a preset permissible value.
Claim 9
Dependent Claim
59 words
An apparatus according to claim 1 and for use with a mask having a pattern formed thereon, wherein said image forming means comprises a mask holder for holding the mask, illumination means for illuminating the mask, controlling means for controlling said illumination means and a projection optical system for projecting the pattern of the mask onto the radiation-sensitive member.
Claim 10
Dependent Claim
40 words
An apparatus according to claim 8, wherein said vibration detecting means comprises a plurality of vibration detecting means one of which is connected to said radiation-sensitive member holding means and another one of which is connected to said mask holder.
Claim 11
Independent Claim
80 words
An apparatus for use with an information bearing member for bearing thereon information, comprising: means for holding the information bearing member; means for recording information on the information bearing member; vibration detecting means for detecting vibration to detect relative movement between said recording means and the information bearing member; and means for permitting the operation of said recording means, said permitting means discriminating whether the relative movement as aforesaid falls within a value not greater than a preset permissible value.
Claim 12
Independent Claim
80 words
An apparatus for use with an information bearing member for bearing thereon information, comprising: means for holding the information bearing member; means for recording information on the information bearing member; vibration detecting means for detecting vibration to detect relative movement between said recording means and the information bearing member; and means for permitting the operation of said recording means, said permitting means discriminating whether the relative movement as aforesaid falls within a value not greater than a preset permissible value.
Claim 13
Dependent Claim
12 words
An apparatus according to claim 10, wherein the permissible value is changeable.
Claim 14
Dependent Claim
30 words
An apparatus according to claim 10, wherein said permitting means operates said recording means when the relative movement as aforesaid falls within a value not greater than the permissible value.
Claim 15
Dependent Claim
50 words
An apparatus according to claim 10 and for use with an original having a pattern formed thereon, wherein said recording means comprises a holder for holding the original, illumination means for illuminating the original and projection optical means for projecting the pattern of the original onto the information bearing member.
