The housing has an opening in a corner. The buffer member includes a first portion fixed inside the housing and a second portion protruding from the opening of the housing to an outside of the housing. An elastic modulus of the second portion of the buffer member is lower than an elastic modulus of a portion of the housing which forms the opening. ## Claims ### Claim 1 A radiation imaging apparatus comprising: a radiation detection panel; a housing configured to accommodate the radiation detection panel, said housing providing an incident plane that is irradiated with radiation, a reversed surface opposite to the incident plane and a side surface connecting the incident plane and the reversed surface; and a buffer member, wherein the housing has an opening in a corner, said opening being formed at the side surface, and the buffer member includes a first portion fixed inside the housing and a second portion protruding from the opening of the housing to an outside of the housing. ### Claim 2 (depends on 1) The apparatus according to claim 1, wherein the first portion of the buffer member is bonded to an inner surface of the housing. ### Claim 3 (depends on 1) The apparatus according to claim 1, wherein the first portion of the buffer member is integrally molded on the housing. ### Claim 4 (depends on 1) The apparatus according to claim 1, wherein the first portion of the buffer member has a frame shape surrounding the radiation detection panel. ### Claim 5 (depends on 1) The apparatus according to claim 1, wherein the first portion of the buffer member extends along a side wall of the housing. ### Claim 6 (depends on 1) The apparatus according to claim 1, wherein the first portion of the buffer member has a concave portion in a surface which is not contact with the housing. ### Claim 7 (depends on 1) The apparatus according to claim 1, wherein the second portion of the buffer member has a step facing a portion, of the housing, which forms the opening and a space is present between the step and the portion. ### Claim 8 (depends on 7) The apparatus according to claim 7, wherein the step has a shape corresponding to at least part of the opening. ### Claim 9 (depends on 1) The apparatus according to claim 1, further comprising a base configured to support the radiation detection panel, wherein the base is in contact with the buffer member. ### Claim 10 (depends on 1) The apparatus according to claim 1, wherein the buffer member includes a first member and a second member having a lower elastic modulus than the first member, the first member is coupled to an inner surface of the housing, and the second portion of the buffer member includes at least part of the second member. ### Claim 11 A radiation imaging apparatus comprising: a radiation detection panel; a housing configured to accommodate the radiation detection panel; and a buffer member, wherein the housing has an opening in a corner, the buffer member includes a first portion present inside the housing and a second portion protruding from the opening of the housing to an outside of the housing, an elastic modulus of the second portion of the buffer member is lower than an elastic modulus of a portion of the housing which forms the opening, and the first portion of the buffer member is disposed on an inner surface of the housing with a frame shape so as to surround the radiation detection panel. ### Claim 12 A radiation imaging system comprising: a radiation imaging apparatus; and a signal processing unit for processing a signal obtained by the radiation imaging apparatus, wherein the radiation imaging apparatus comprises: a radiation detection panel; a housing configured to accommodate the radiation detection panel, said housing providing an incident plane that is irradiated with radiation, a reversed surface opposite to the incident plane and a side surface connecting the incident plane and the reversed surface; and a buffer member, wherein the housing has an opening in a corner, said opening being formed at the side surface, and the buffer member includes a first portion fixed inside the housing and a second portion protruding from the opening of the housing to an outside of the housing. ### Claim 13 (depends on 1) The apparatus according to claim 1, wherein an elastic modulus of the second portion of the buffer member is lower than an elastic modulus of a portion of the housing which forms the opening. ### Claim 14 (depends on 1) The apparatus according to claim 1, wherein the opening is formed such that the corner of the housing is cut off and the buffer member is disposed in the corner so as to compensate the cut-off portion. ### Claim 15 (depends on 1) The apparatus according to claim 1, wherein the first portion of the buffer member faces an internal space of the housing where the radiation detection panel is located. ### Claim 16 (depends on 1) The apparatus according to claim 1, wherein the opening penetrates the housing.
