A data transmission system includes a polling modem and a central control unit that receives a response signal from a terminal. A data transmission central control unit performs polling type transmission to transmit an information data unit to the terminal that has requested the information data unit. The central control unit also performs loop type transmission to cyclically transmit information data units with their loop flags being set to the terminals in succession. The control portion in the terminals selects the transmission that requires the shortest waiting time.

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.

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.

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.

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. Control means are connected to the communication device and the exposing device, for applying to the exposing device the picture signals received from the communication device as the image signals, to thereby form on the photosensitive medium the latent image represented by the picture signals.

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.

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.

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.
