An image erasing device for erasing an image formed erasably on a recording medium is provided. An image display apparatus equipped with the image erasing device, and an image recording apparatus equipped with the image erasing device are also provided. The image erasing device includes a device for feeding the recording medium stepwise, and a cleaner for erasing the image forming on the recording medium by independently scanning the cleaner perpendicularly to the direction of feeding of the recording medium while the recording medium stays stationary.

There is provided an image display apparatus and an image erasing method, by which a color image made of an ink can be displayed by fixing the ink on the recording medium, and, when it is desired to erase the color image, the color image on the recording medium can be erased by image erasing means. Therefore, the present invention comprises ink application means for applying an ink onto recording medium in accordance with image data, and image erasing means for erasing the image formed on recording medium by ink application means , wherein, when the solubility parameter (SP value) of the substance remaining on recording medium after applying the ink is taken as SP , the SP value of the substance constituting the surface of the recording medium is taken as SP , and the SP value of the substance constituting the surface of the image erasing means is taken as SP , said SP , SP and SP satisfy the relationship &verbar;SP &minus;SP &verbar;>&verbar;SP &minus;SP &verbar;.

Image display apparatus, and ink and image erasing method for use in the apparatus

A method of producing an impact resistant liquid crystal display, for a nematic liquid crystal display or a chiral smectic ferroelectric liquid crystal display, includes the steps of fixing a liquid crystal panel onto a panel fixing member so as to substantially expose the liquid crystal panel through an opening of the panel fixing member and disposing an elastic member along a periphery of the panel fixing member. The elastic member is affixed to a supporting member so as to define an almost closed space with the liquid crystal panel, the panel fixing member, the elastic member and the supporting member, whereby an air damping effect is created to suppress flexural deformation of the liquid crystal panel.

Impact resistant liquid crystal apparatus

A liquid crystal contained in a liquid crystal reservoir is applied to an injection port of a blank liquid crystal panel in a vacuum chamber, and the vacuum chamber is restored to the atmospheric pressure to inject the applied liquid crystal into the liquid crystal panel through the injection port. Herein, the liquid crystal, particularly a ferroelectric liquid crystal having a high viscosity, is effectively used for filling the liquid crystal panel with a minimum loss by using a transfer member moving between the liquid crystal reservoir and the liquid crystal panel.

Process for producing liquid crystal panel

A liquid crystal display apparatus is provided with a liquid crystal panel comprising a pair of substrates each provided with an electrode and a liquid crystal disposed between the pair of substrates. A supporting member having a frame supports the liquid crystal panel, and an elastic member for secures the liquid crystal panel in a floating state to the frame of the supporting member so as to define an almost closed space enclosed with the liquid crystal panel, the supporting member and the elastic member. A backlight illuminates the liquid crystal panel below the supporting member so as to define the almost closed space enclosed with the liquid crystal panel, the supporting member, the elastic member and the backlight.

A recording medium comprising a substrate, a recording layer formed thereupon, and an anticorrosive layer which covers the recording layer and contains a chemical to prevent the corrosion of the recording layer.

Recording medium

An image forming apparatus comprises an exposure light source, an image bearing member and a printer head interposed therebetween. The printer head has a micro-shutter array which comprises a plurality of micro-shutters arranged in a matrix comprising a plurality of rows and a plurality of columns. Each micro-shutter comprises a first electrode connected to a terminal of a thin film transistor, a second electrode forming a common electrode and a liquid crystal interposed therebetween. On the first electrode is further provided an opposing conductor film through an insulating film, whereby a charge storage capacitor is formed. Because of the charge storage capacitor, an effective voltage applied across the liquid crystal is kept at a high level, whereby an optical signal with good contrast is given to the image bearing member even when the printer head is driven according to a high degree of time-division scheme.

Image forming apparatus

A recording medium is provided which comprises (a) a first recording layer; (b) a second recording layer provided in contiguity to the first recording layer; and (c) a separation layer for spatially separating the first and second recording layer. The first recording layer has a sufficient film thickness not to permit the recording to be effected on the second recording layer, while the recording operation is performed on the first recording layer, and the recording operation is effected on the second recording layer at positions corresponding to defective portions in the first recording layer.
