摘要:
A combined home-use-television set/calculator electronic system comprising a control unit for conducting arithmetic calculations and for displaying calculation results on an image screen of the home-use-television set. A keyboard unit is exchangeably connected to the control unit for increasing operation abilities of the combined home-use-television set/calculator electronic system. A read only memory cartridge is exchangeably secured to the control unit. A read only memory corresponding to a selected keyboard unit is secured to the control unit for developing operation instruction signals which are required for performing the arithmetic calculations associated with the selected keyboard unit.

A new and useful combination of a radio receiver, a television receiver, a tape recorder and an electronic calculator is described. A display (for example, a cathode ray tube) of the television receiver is connected to serve also as a display for the electronic calculator. Data may be introduced into the calculator via the tape recorder and recorded into the tape recorder. The television receiver serves a display and the tape recorder serves as an external storage, with respect to the calculator.

A PC is comprised of a processing device 1 which performs processings such as converting manipulated data into a human-comprehensible format or data updating according to entered information, a display device 3 which presents information such as images and sounds to the user, a storage device 4 which stores data temporarily converted into information such as data to be handled, images and sounds, and a connection device 5 which establishes connection with other PCs and PDAs via a connection medium such as the Internet or a USB cable. This configuration allows transfer of application data by a program capable of manipulating such data after its conversion into basic data and allows application data to be manipulated (worked with) even on PDAs lacking means for directly handling application data.

An interface circuit connects a computer and peripheral units. The interface circuit includes a battery power source that drives a signal conversion circuit. A detector circuit detects levels of signals received from the computer, the signals being indicative of a power ON/OFF status of the computer. A control circuit controls the operation of the signal conversion circuit so that the built-in battery source will not be dissipated while the computer is not in operation. The control circuit also inhibits operation of the signal conversion circuit when the detector circuit indicates that condition of the battery source has deteriorated.

An e-mail sending/receiving system is furnished with a host computer having a storage section for storing mails, a first control device for extracting the mails to be sent to a terminal in accordance with priorities assigned to the mails. Thus, the user can receive mails with higher priorities, such as urgent or important mails, in a secure manner without worrying about an available memory capacity of the terminal.
摘要:
A data receiving apparatus in which mail from a sender for which a secret setting is made cannot be directly confirmed. In this data receiving apparatus, when a password is not inputted or when an incorrect password is inputted by a user when a display is in a state of password input screen, the display indicates only a received mail list for mails from persons who are identified by personal data sets stored in advance which do not have a secret flag. The display also indicates the number of all the mail data sets, including the mail data sets from persons for which the secret flag is set.

An information processing apparatus having a main body and a lid body is configured so that the lid body can be switched between a closed state, a stacked state, a double screen state and an inverted state. Each of the main body and the lid body has a display section for displaying information and an input section composed of a transparent tablet and provided on the display section. As a sensor or the like detects the lid body in one of the four states, a control section of the information processing apparatus controls the display section so that a screen on the display section is appropriate to the detected state of the lid body. The control section also controls the lighting section for lighting the display section appropriately to the detected state of the lid body. This realizes appropriate display in accordance with usages of the information processing apparatus and offers an easy-to-operate and easy-to-use information processing apparatus. Besides, the lighting section is turned on/off according to needs, and therefore it is possible to prevent heat generation and to restrain power consumption.

An input/display apparatus for handwritten characters is capable of quickly inputting handwritten characters, freely editing characters inputted, and storing a lot of handwritten characters with a limited storing capacity. On a display panel provided with a display surface, the orthogonal coordinates of which are preset, a touch panel provided. An input surface of the touch panel, the orthogonal coordinates of which are preset, is disposed in such a way that the display surface and the input surface overlap each other. When the input surface is indicated with an input pen, the indicated coordinate point is outputted. At the time of handwriting input, when the input surface in the input/display area for characters is continuously indicated, coordinate points on the display surface corresponding to the plurality of indicated coordinate points are displayed. After the handwriting input is over, stroke data consisting of coordinate points extracted on the basis of predetermined references from among a plurality of coordinate points outputted from the touch panel at the time of handwriting input are prepared. The stroke data are displayed by being converted to a size corresponding to the width of the line set in the area after the display position of the cursor.

An electronic apparatus such as a computer is of the type in which the computer is energized for wake up in accordance with a timer or an external key input. Prior to the system wake up by the timer or external key input, an alarm is generated for a predetermined time, indicating that the system wake up is being caused and the peripheral interface or machine should not be electrically coupled to the computer.
