Abstract: A portable electronic computer or calculator is characterized in that it calculates a functional operation on the previously calculated result by simply actuating a function key switch while the result is being displayed. It is unnecessary to actuate any entry key switch. In a specific form of the present invention, the computer may calculate a functional operation on numerical data in response to input of a function command, the numerical data being either newly inputted or previously calculated.
Abstract: An electronic translator comprises a specifying device for specifying letters to be input. An input device cooperates with the specifying device to input the specified letters into the electronic translator. The translator also includes a memory for memorizing a plurality of words containing the input letters, an access circuit for addressing the memory to retrieve such words and a display responsive to the access circuit for displaying the retrieved words and translated equivalent words. The specifying device is operated with only a few keys to enable input of any letter of the alphabet.
Abstract: A portable general-purpose electronic apparatus which is characterized in that; a memory unit can be inserted into the housing via an inlet so that any desired display information memorized by the memory unit can be displayed on a screen display, and as a result, a variety of information can be conveniently displayed by merely changing the memory unit. Consequently, an extremely useful general-purpose electronic apparatus can be realized by memorizing any desired information, for example, such as game function and other data of interest.
Abstract: Disclosed hereinbelow is an automatic graphic printer which is characterized in that; it automatically sets the scale information of the graphic axes as a function of the sample data value, and therefore, even if designation of an information related to complex scales is deleted, such a scale information based on the sample data can be automatically set, and as a result, any of the conventional graphs can be drawn within a shorter period of time than before by using simplified designation means. In addition, plotting position of the sample data can be set in any suitable position on the graph so that an optimum scale can easily be provided.

Abstract: A timepiece has a time set mode and another time-related mode. It comprises a logic circuit for recognizing the time set mode and an electroacoustic transducer responsive to the logic circuit for providing a particular sound in succession when the timepiece is in the time set mode. The present timepiece makes it easy for the user, especially a blind or weak-eyed person, to recognize that the time set mode is in effect.
Abstract: An electronic calculator is provided which generates confirmation sounds identifying actual depression of any keys of a keyboard. The calculator includes a piezoelectric acoustic element which is responsive to key signals derived from a processor unit when any keys of the keyboard are manually operated. The calculator generates these sounds only for a fixed period of time starting with actual depression of any keys. The processor unit generates key-strobe signals which are input to the keys on the keyboard. Each key has its own key-strobe signal, and, when depressed, the signal is passed to the processor uniquely identifying each key. The processor generates sound instruction signals indicative of normal and erroneous operational states in the calculator in accordance with the received key-strobe signals. An audible confirmation or alarm sound is then generated in accordance with the sound instruction signal.
Abstract: A timepiece having a speech synthesizer output device is disclosed herein. The speech synthesizer is responsive to sound input such as human voices (e.g., what time is it?) or the sound of clapping of hands to provide an audible indication of time information. The intensity of the audible indication is varied with the intensity of the sound input.
Abstract: An electronic digital tape measure includes a flexible tape, a detector, and a digital display. A keyboard unit and a control circuit may be further included for acting as an electronic calculator.
