Abstract: When a process unit of the image forming apparatus has reached the end of its service life, the apparatus prints recovery information on a sheet, such as an officially approved "postage paid" mark, a recipient's name, the recipient's address and the recipient's postal code. The printed information tells the user that the service life of the process unit has expired, that the unit is a consumable component to be recovered for recycling, and that the unit is to be returned to the designated address.

Abstract: In an image recording apparatus in which toner carried on a toner carry roller is supplied to an aperture electrode in contact with the aperture electrode, the aperture electrode is elastically supported through an electrode supporter formed of elastomer such as rubber, and the toner carry roller is designed in a barrel shape. Therefore, the contact pressure between the aperture electrode and the toner carry roller is constant over all positions due to the expanding action of the electrode supporter and the toner is uniformly supplied to all the apertures of the aperture electrode. As a result, a uniform-density toner image can be formed over all the positions.

Abstract: A picture encoding system which performs a prediction of picture element values within a block having a plurality of picture elements into which an original picture is divided, a discrete sine transform with respect to prediction error signals for obtaining a transform coefficient, a quantization of the transform coefficient for encoding quantized indexes, an inverse quantization of the quantized indexes for reproduction of the transform coefficient, an inverse discrete sine transform of the reproduced coefficient to reproduce the prediction error signal, and an addition thereto of the predicted picture element value for reproducing the picture element values within the block to employ them in predicting a next stage block to be encoded, whereby the block can be minimized in size while simplifying required transform operation.

Abstract: A word processor including a main unit, a connector for connecting the main unit to a large-sized display, and a display controller for controlling the large-sized display. The main unit includes an input device for entering character data representative of characters, a memory for storing the character data, and a small-sized display capable of displaying up to a predetermined number of characters entered through the input device. The large-sized display has a larger display capacity than the small-sized display, and is controlled by the display controller so as to display the characters according to the character data stored in the memory.

Abstract: An image recording system including a photosensitive medium having a layer of microcapsules formed on a substrate, each of the microcapsules having a photosensitive resin which is curable upon exposure to a radiation, and a colorless chromogenic material or color former which is capable of chemically reacting with a developer material, to form a visible image. The system further includes an exposing device for forming a latent image on the photosensitive medium according to image signals, by exposure of the medium to the radiation. The latent image is developed into a visible image. A communication device is provided for translating facsimile signals into corresponding picture signals. The facsimile signals are received from a remote facsimile transmitter through a communication channel and represent an image of a subject copy.

Abstract: Disclosed is a typing device wherein relational data such as correct spelling word may substitute the printed word. When the printed data is substituted by the relational data, the succeeding printed data posterior to said printed data to be substituted is visually represented on a display.

Abstract: A photosensitive recording medium having a multiplicity of microcapsules formed on a substrate, and a developer material, each microcapsule having a photosensitive resin and a chromogenic material which reacts with the developer layer to form a colored image spot. The microcapsules comprising a plurality of microcapsule groups which are sensitive to radiations having different wavelength bands, or which are sensitive to different intensities of the radiation. An image recording system is provided with an illuminating device for generating radiations of different wavelengths falling within the wavelength bands of the microcapsule groups, or a radiation of variable intensity. The recording system has a selector for selecting at least one of the radiations of the different wavelengths, or one of the intensity levels of the radiation, in order to adjust the contrast of the images formed on the medium, with respect to non-image areas on the medium.

Abstract: The present electronic typewriter executes a spelling check control and, more specifically, judges whether or not a word in a dictionary memory identical to an inputted word exists. If a word does not exists, the word printing operation or sweep display of this word is automatically interrupted by a central processing unit. The present invention further provides an electronic typewriter wherein the operator is freed of the spelling check task and high-speed key-in operation can be achieved by preventing misspelled words from being printed.

Abstract: An abnormality supervising system compares an input picture with a previously stored reference picture having no abnormality, provides a compared picture signal to an abnormality discrimination means having preliminarily stored information for abnormality discrimination, and, upon presence of an abnormality, operates an output means for informing operation, whereby the abnormality discrimination means can effectively attain the abnormality discrimination on the basis of the preliminarily stored information, in a highly reliable manner.

Abstract: An apparatus for entering coordinate data for moving a cursor ona screen of a CRT display in response to movements of a manually movable unit on a planar board, comprising a detecting device disposed on the manually movable unit to detect amounts of movement of the manually movable unit in X- and Y-axis directions on the planar board, a magnification selector for selecting one of plural values of magnification of the detected amounts of movement of the movable unit, and a data processor for obtaining distances of movements of the cursor on the display screen, by multiplying the detected amounts of movement of the movable unit by the selected value of magnification.

Abstract: An apparatus for driving a magnetic disk for information storage and retrieval, comprising a battery for supplying electric power to a first actuator for rotating the magnetic disk, and to a second actuator for moving a magnetic head across a surface of the magnetic disk and energizing the head to write information on and read the information from the magnetic disk. The apparatus further comprising a detector for sensing a voltage level of the battery, and generating a voltage-drop signal when the voltage level of the battery has fallen below a preset limit. A control unit is provided for controlling the first and second actuators. The control unit is responsive to the voltage-drop signal to inhibit the starting of an access to the magnetic disk, or inhibit the operation of the first actuator.

Abstract: An electronic typewriter, comprising: (a) a keyboard (2) generating a signal corresponding to a depressed key and comprising at least a plurality of character keys (5) for inputting character data, a space key (4) for separating said character data into words and a release key (6), a dictionary memory (12) for storing a plurality of words, a working memory (13) for sequentially storing said plurality of words, a spelling check control means (11) for reading out word data from said dictionary memory (12) as well as said plurality of words inputted via said keyboard, comparing the spelling of said words with said word data, and judging whether or not the spelling of said words is correct, means for disabling said spelling check control means (11), said means disabling said spelling check control means (11) only for a first word inputted after the depression of said release key (6) of said keyboard (2), and visible outputting means (8), (9) for outputting input data visibly.
