  • Patent number: 5646872
    Abstract: An information processing apparatus of built-in printer type which is excellent in portability and operability, comprising a printer paper receptacle arranged on the lower side of a keyboard, and a printer unit constructed on the side of the keyboard normally facing the user. Further, a printed paper receptacle is arranged on the rear side of a display unit. The paper ejection slit of the printer unit and the paper insertion slit of the printed paper receptacle are formed so as to be united when the display unit is closed. When a print operation is performed with the display unit closed, a sheet of paper printed on by the printer unit is received into the printed paper receptacle through the ejection slit as well as the insertion slit, automatically in the closed state of the apparatus.

  • Patent number: 5396443
    Abstract: An information processing apparatus can save an electric power when it is not in use and can be made active immediately after an operation medium such as a pen and a finger or the user approaches or comes in contact with the apparatus, the arrangement being such that a housing portion of the apparatus includes therein a sensor for detecting the approach or contact of a user operation medium or user and a state display unit for informing the user that the apparatus is in the active state or in the standby state, a power saving control unit controls a controlled object concerning a power consumption in response to the approach, contact or separation of the operation medium or user, and a timer included in the electric power saving control unit determines whether or not the operation medium or user is separate from the apparatus.

  • Patent number: 5377330
    Abstract: A document editing apparatus in which image data such as data representing an illustration is converted to total digital image data pertaining to a complete image. The total digital image data is divided into a predetermined number of pieces that each include a predetermined number of dots. The divided digital image data is stored in memory as external character data. The total digital image data is converted into a divided digital character data assembly and registered as a digital character data block in memory. Next, character data representing document data is inputted into the memory. The digital character data block and the character data exist together in memory as coexisting editing data. Since the digital image data exists together with the character data in memory, editing processing of document data including the character data and the digital image data can be carried out at one time during operation processing.

  • Patent number: 5084773
    Abstract: An image read processing apparatus includes an image reading unit movable relative to a medium surface on which an image to be read is recorded. The image reading unit reads the image on the medium surface by repeating a line scanning in a direction substantially perpendicular to the direction of movement of the image reading unit relative to the medium surface during a period of time when the direction of the relative movement is a predetermined direction, and outputs image data representative of the read image and movement data concerning the relative movement. The apparatus further includes a detector for detecting the direction of the movement of the image reading unit relative to the medium surface on the basis of the movement data. When the detected movement direction is a direction substantially different from the predetermined direction, an other-direction moving distance is determined by which the image reading unit has been moved in the different direction.

  • Patent number: 4890256
    Abstract: A check up key and a check up display speed key are provided on the inputting apparatus. When the check up key is inputted, a check up display speed controlling apparatus displays the character line of the already inputted document with a continuous shifting of the character line of the already inputted document. When the check up display speed key is inputted, the check up display speed controlling apparatus changes the check up display speed for the display. During the check up of the already inputted document, the character line of the already inputted document is displayed with a continuous shifting and also the check up display speed for the display is set freely, so that the character line of the already inputted document can be edited easily.

  • Patent number: 4887165
    Abstract: A document editing apparatus comprises an apparatus body, an image reader and a detachable signal cable disconnectably connecting the image reader to the apparatus body. The image reader comprises an image sensor, a connector for connection to an externally inserted card-type semiconductor memory integrated circuit package for storing image data, a selector switch for selecting image data to be stored, a light-emitting diode for displaying an insufficient residual memory capacity of the package, and a control circuit. Image data read by the image sensor is selectively stored in the semiconductor memory integrated circuit package inserted into the image reader or in the apparatus body.

  • Patent number: 4825308
    Abstract: A data processing system in which a phase judging data portion is added to the head of data to be registered in a tape recorder so that a sampling timing may be changed when the phase of the sampling signal of the phase judging data portion in the data reproduced from the tape recorder is not coincident with a predetermined value.
