Abstract: A data processing apparatus comprises input, file update, display and print processing units which are independently operated and linked to each other. Arbitrary word labels can independently be set in each processing unit. Each processing unit performs only an operation defined by the word labels. The data processed by one processing unit can be used as a source data based on which the succeeding linked processing unit performs another processing operation.

Abstract: A table memory is provided for selecting types of files to be updated in accordance with identification codes designating types of transactions. When a transaction occurs, the corresponding transaction record and the identification code indicating the type of transaction are generated. Data from the table memory is retrieved in accordance with the identification code to select all the files to be updated. The selected files are sequentially updated in accordance with the transaction record.

Abstract: The data display device has a memory section to store a specific day or days for different countries or regions of the world. The specific day data read out from the memory section, and which is peculiar to a specific country or region, is transferred to a display section to be displayed thereby.

Abstract: An electronic musical instrument comprises a plurality of musical tone control units each having a tone waveform producing circuit, a volume envelope circuit, a filter circuit and other circuits. A given musical tone data can be preset in each musical tone control unit. Musical tone signals produced by the musical tone control units are synthesized to provide an effective musical tone.

Abstract: In an electronic musical instrument which is arranged to produce musical tones belonging to the selected one of many different types of musical instruments and having a number of player-operable selection keys respectively corresponding to the number of types of musical instrument sounds desired, the improvement wherein means is provided for generating a sample tone belonging to that type of musical instrument specified by one of the above-mentioned selection keys at a prescribed pitch and period simply by depressing only once a particular selection key, without taking the trouble of successively depressing individual performance keys, thereby facilitating the selection of a desired type of musical instrument by the player.

Abstract: An electronic timepiece has an optical display device for displaying time in digits and an alarm time indicator for setting an alarm time in terms of the position of a pointer. The position of the pointer is electronically detected and is applied as alarm time data to a time counting circuit. When current time is coincident with the alarm time set by the pointer, the alarm is given.

Abstract: An electronic musical instrument of simple arrangement wherein a plurality of musical tones of different musical instrument types are preset; musical tones of a desired musical instrument type is first selected; musical tones belonging to the selected one of the plural musical instrument types are played by performance keys; the performance keys are concurrently used for selection of musical tones of the desired musical instrument type, and which comprises a changeover switch for determining the application of the performance keys for the original purpose or for selection of a desired musical instrument type, thereby eliminating the necessity of providing separate musical instrument type-selecting key or keys in addition to the performance keys.

Abstract: A key input apparatus is provided with a plurality of input operation keys and a time signal generating circuit which in correspondence to the number of these input keys performs a step operation to generate in turn a different timing signal. Input signals produced by actuation of the input operation keys pass through a group of first AND gates in synchronism with the corresponding timing signals generated from the timing signal generating circuit. A shift register having bits corresponding in number to the gates of the group of first AND gates receives the output signal of the AND gates via an OR gate. The output signal from the OR gate is applied to one input terminal of a second AND gate of which the other input terminal is coupled with the last bit position of the shift register through an inverter. The outputting operation of the second AND gate is controlled by the shift register and inverter.
