Claim 13

Dependent Claim 24 words

A device according to claim 10, in which at least one of said holding members is provided on an inner wall of said casing.

Claim 14

Dependent Claim 31 words

A device according to claim 12, in which said holding member is located on front and rear walls of said casing corresponding to leading and trailing edges of the recording medium.

Claim 15

Dependent Claim 22 words

A device according to claim 11, in which said holding member has a napped cloth at the side wall of said casing.

Claim 16

Dependent Claim 18 words

A device according to claim 9, in which said holding means is made of a fiber brush material.

Claim 17

Dependent Claim 19 words

A device according to claim 15, in which said fiber brush is provided across the thickness of said casing.

Claim 18

Dependent Claim 16 words

A device according to claim 16, in which said fiber brush material includes fibers curved downward.

Claim 19

Dependent Claim 44 words

A device according to claim 17, in which said holding means includes a rotatable roller located on an upper inner wall portion of said casing and a fiber brush material located below said rotatable roller on a lower inner wall portion of the casing.

Claim 20

Independent Claim 162 words

A device for holding a radiation image recording medium in an X-ray diagnostic apparatus, comprising: a casing having an opening through which the recording medium is placed therein, said casing being removably mounted in said X-ray diagnostic apparatus; a light shutting plate including a main plate section for closing said opening of said casing and a front section arranged at an angle substantially perpendicular to said main plate section, said light shutting plate being removable from said casing; a handle for detaching said casing from said X-ray diagnostic apparatus and for carrying said casing, said handle being fixed to said front section of said light shutting plate; and locking means for bringing said light shutting plate into locking engagement with said casing at times when said light shutting plate closes said opening of said casing, whereby said casing can be removed from said X-ray diagnostic apparatus by pulling said handle only if said light shutting plate closes said opening of said casing.

Claim 21

Independent Claim 162 words

A device for holding a radiation image recording medium in an X-ray diagnostic apparatus, comprising: a casing having an opening through which the recording medium is placed therein, said casing being removably mounted in said X-ray diagnostic apparatus; a light shutting plate including a main plate section for closing said opening of said casing and a front section arranged at an angle substantially perpendicular to said main plate section, said light shutting plate being removable from said casing; a handle for detaching said casing from said X-ray diagnostic apparatus and for carrying said casing, said handle being fixed to said front section of said light shutting plate; and locking means for bringing said light shutting plate into locking engagement with said casing at times when said light shutting plate closes said opening of said casing, whereby said casing can be removed from said X-ray diagnostic apparatus by pulling said handle only if said light shutting plate closes said opening of said casing.
