A portable and highly compact copier for photographically copying a selected portion of an illuminated image. The copier includes a lighttight housing (24) having an opening (26) therein and having a support for temporarily maintaining photosensitive material at a focal plane within the copier housing. An array of image-transferring cylindrical microlenses (36), each microlens having an image end and an object end, is slidably mounted in the housing opening with the image ends adjacent the focal plane and with the object ends facing outwardly of the copier housing opening. An electrical drive motor is provided which is mechanically coupled to the microlens array. A self-retracting shade (50) arrangement forms a slidable lighttight seal between the microlens array and structure forming the housing opening such that all of the light passing though the housing opening and to the copier housing focal plane must pass through the microlens array. When the drive motor is actuated, the microlens array coupled thereto is driven across the housing opening to thereby cause an illuminated image located at the copier housing opening to be transferred to the housing focal plane and to photosensitive material positioned thereat.
