This invention consists in a nonimaging device for concentration or collimation of radiation on a receiver or from an emitter, depending on the case. caused by print jobs which are secured by a job security function and which are forgotten to output and accumulated in a storage device. The general-purpose communication device may, for example, comprise a cardiac sensor disposed on the mobile communication device, which may be utilized to acquire cardiac information during use of the mobile communication device. , for the delivery of biologically compatible materials, and release thereof in active form. With this arrangement, it is possible to provide a display device which enhances efficiency in utilization of light emitted from the illumination device and increases luminance of the display device without such display problems as bright lines and moir\xe9.
