ABSTRACT:
A light guide member comprises an optical block provided with a light input face positioned close to and approximately in parallel with a stimulable phosphar sheet carrying a radiation image stored therein, and a dichroic optical plane formed above the light input face at an angle larger than 45.degree. with respect to the light input face. The dichroic optical plane transmits stimulating rays and reflects light emitted by the stimulable phosphor sheet upon exposure to stimulating rays. The optical block is also provided with upper and lower total reflection planes extending approximately in parallel with the path of light reflected by the dichroic optical plane after entering from the light input face approximately normal thereto.
