Abstract
An intermediate member is disposed between a peripheral region and a third region, having been fixed to an imaging plate and a retaining plate. The intermediate member does not extend to between at least a part of a middle region and a forth region, such that a void is provided. The difference between the linear expansion coefficient of the imaging plate and the linear expansion coefficient of the intermediate member is smaller than the difference between the linear expansion coefficient of the retaining plate and the linear expansion coefficient of the intermediate member.
Claims20
An imaging apparatus comprising:
- an imaging plate having a front face into which light enters and a back face having a middle region including a center and a peripheral region surrounding the middle region;
- a retaining plate having a retaining face configured to retain said imaging plate from said back face side;
- and
- an intermediate member disposed between said peripheral region and said retaining face by being fixed to said imaging plate and said retaining plate;
- wherein said intermediate member does not extend between
- at least a part of said middle region, and
- at least a part of a facing region on a plane extended from said retaining face, the facing region facing said middle region, and a void is formed therebetween;
- and wherein an arithmetic difference between a linear expansion coefficient of said imaging plate and a linear expansion coefficient of said intermediate member is less than an arithmetic difference between a linear expansion coefficient of said retaining plate and the linear expansion coefficient of said intermediate member.
An imaging apparatus comprising:
- an imaging plate, having a front face into which light enters, and a back face having a middle region including a center and a peripheral region surrounding the middle region;
- a retaining plate having a retaining face configured to retain said imaging plate from said back face side;
- and
- an intermediate member disposed between said peripheral region and said retaining face by being fixed to said imaging plate and said retaining plate;
- wherein the area of said front face is 300 mm2 or greater;
- and wherein said intermediate member does not extend to between
- at least a part of said middle region, and
- at least a part of a facing region on a plane extended from said retaining face, said middle region, and a void is formed therebetween;
- and wherein the primary material of said imaging plate and said intermediate member is silicon, and the primary material of said retaining plate is a nonmagnetic metal.
