Abstract: An electronic apparatus with calendar is provided incorporating calculation circuitry and a display portion for displaying the up to thirty-one dates in a month and a day of the week so that a user is provided with a visual indication representative of the day of the week and the date of the month. The date of the month may be directly indicated or indicated indirectly by the day of the week indication.

Abstract: A calculator is provided having a display cell formed from a passive display material, regions of which are rendered visible by segmented electrodes. The display cell is driven by the application of selected driving signals to respective segment electrodes along display-driving lines coupled to said segment electrodes. A large-scale integrated circuit includes circuitry for producing said driving signals for application to said display-driving lines and calculator circuitry. A keyboard device is provided having an output coupled to said large-scale integrated circuit and a plurality of inputs coupled to selected of said display-driving lines, said large-scale integrated circuit including circuitry for selectively applying keyboard input signals to said selected of said display-driving lines for application to said keyboard inputs when said keyboard is utilized.

Abstract: A dynamically driven printer is provided for printing the output of a device having a memory register, the printer including print means operable directly from said memory register without an intervening temporary memory register in a manner corresponding to the operation of a segmented digital electronic display. The operating periods of the print means and memory register need not be synchronized. The print means may include a plurality of segment printing devices at each digit position, corresponding segment printing devices at each digit position being coupled together for simultaneous receipt of driving signals generated in response to the output of the main memory register. Each of the digit positions is sequentially actuated to effect printing.
