An information display system in which information can be referred to without a power supply anytime and anywhere like information recorded on paper, and in which information can be rewritten repeatedly, and such information can be outputted instantaneously and in large numbers. An image accepted by an image input unit (in FIG.) is converted by a signal processing unit () into a data format for writing the image into a display unit (). An information sending unit () controls plural display elements (-to-N), and it sends the information to-be-displayed to the plural display elements (-to-N) in parallel through a connector array (). Thus, the image accepted by the image input unit () can be instantaneously displayed on the multiple display elements (-to-N). The display elements (-to-M) have storability. Therefore, even when the display elements (-to-N) have been detached from the connector array (), the displayed images are kept as they are, and they can be referred to anytime and anywhere.

Information display system

An input-output unit includes a display unit having a bendable display screen for displaying information on the bendable display screen; and a pressure-sensitive input unit containing detection means being provided below the display screen for detecting a position on the bendable display screen in response to press pressure from a view side of the bendable display screen.

Input-output unit

A picture image processor wherein a white reference value with respect to an analog output of video data is established in response to a change in luminous energy, and the white reference output is compared with the video data output to obtain a binary signal, and this signal is stored in a memory system; then, the stored signal is subjected to a digital-to-analog conversion to form a reference signal, which is inputted to an A/D converter in synchronism with the respective picture elements of an original reading signal, and/or a dark or bright voltage value of the image sensor which has been previously stored is corrected on the basis of such gain from an amplifying means which changes automatically, and the output of the above image sensor is corrected based on the voltage value thus corrected.

Picture image processor

Magnetic recording arrangement, for example, in a thermomagnetographic plain-paper printer, produces a latent magnetic image on a magnetic recording medium which is composed of a ferromagnetic layer, first magnetized along a predetermined direction before forming the latent magnetic image, and a magnetic layer of high permeability to be converted into a paramagnetic layer by being subjected to the heat from a heating head until the layer is heated to its Curie point or above. The magnetic layers are respectively laminated to opposite sides of a base layer, the heating head being placed at the opposite side of the base layer from the ferromagnetic layer so as to remain out of contact with the ferromagnetic layer, thus making the cleaning of the heating head substantially unnecessary while keeping the latent magnetic image of high quality. In the magnetic recording medium, a direct-current magnetic field of the opposite sense as the magnetized direction of the ferromagnetic layer, or an alternating-current magnetic field the phase of which is reversed at positions corresponding to opposite ends of at least a paramagnetized part, is applied to the paramagnetized part of the high permeable magnetic layer thus forming a magnetic latent image on the ferromagnetic layer by leakage of the magnetic flux from the paramagnetized part to the ferromagnetic layer.
