A portable radiographic imaging apparatus is provided which includes a system for facilitating proper alignment of a capturing section of the apparatus with a ray source while a subject is positioned therebetween. The apparatus includes a sensor having an effective capturing area which includes devices for converting rays into electrical signals; a casing enclosing the sensor; and portions formed on the casing for indicating a target capturing area aligned with and having a shape similar to the effective capturing area. A boundary of the effective capturing area is perceivable by touching the portions, thereby allowing an operator to recognize offset between the subject and the capturing section during alignment/positioning of the capturing section with respect to the subject and the ray source.
