A music navigator provides a visual image indication or presentation of fingering motion of a hand in playing notes. In an embodiment, the music navigator employs a fingered music storage and a hand image device. When music is played on a keyboard instrument, the music navigator reads fingered music data and selects appropriate hand image data indicative of fingering motion (e.g., turning over or under of a finger) in playing a current note for visual display. In another embodiment, the music navigator provides a sequence of hand images representative of fingering motion in playing notes in a motion picture manner.

An output control apparatus is interposed between a host computer for generating data and a printer, and controls the printer. The control apparatus includes a plurality of data generators, a discriminator, a controller and a notifying device. The data generators interpret a plurality of printer languages and perform control processing. The discriminator analyzes received data and specifies by which of the plurality of data generators control based upon the received data is to be carried out. The controller, in a case where one data generator is not specified by the discriminator and an error resulting from interpretation failure occurs during the course of processing by one data generator selected under prescribed conditions, causes the discriminator to re-execute processing based upon data in which the interpretation failure occurred. The notifying device notifies of a request for re-transmission of data in a case where one of the data generators is specified anew by the controller.

Method and apparatus for controlling an output device based on received

Electronic equipment of the invention includes a keyboard for inputting character data, a memory for storing the character data input from the keyboard, a printer for printing the character data stored in the memory, and a display for displaying the memory contents. The memory consists of a buffer for temporarily storing the character data, a cursor pointer indicating a cursor position on the display, an end pointer indicating a position immediately succeeding the position of the last character input from the keyboard, and a head pointer indicating the printing head position of the printer. The keyboard includes a relocation key in addition to various character input keys. When the relocation key is depressed, the cursor is moved to a position indicated by the cursor pointer, and when depressed again, the cursor is moved to the position indicated by the end pointer, thus facilitating correction of input errors.

An electronic apparatus such as an electronic typewriter includes a display device and has a plurality of modes of operation selectable by an operator. The operation mode selected by the operator is displayed on the display device that can also display character data input to the apparatus by an input device such as a keyboard. The display device displays the selected mode after displayed character data is printed in response to the operation, for example, of a carriage return key when a line-by-line printing mode is selected or a space key when a word-by-word printing mode is selected.

A printer having an underlining function includes an underline position memory. Each bit of the underline position memory is allotted to each printable position, and contents of bits corresponding to the underline positions are inverted.

Printer with underlining function

An electronic apparatus with pattern recognition function is disclosed. This apparatus has one key pad used for inputting both command data for giving instruction for controlling the apparatus and hand-writing data to be pattern-recognized. The input data are processed depending on which area of the key pad they have been input in. A CPU is also included for deciding how to process the input data. An operator can input both handwriting data and command data from one single key pad and thus troublesome operations, such as inputting handwriting data from a key pad and also inputting command data from a key board, can be eliminated.

An input processor such as table calculator comprises input means for putting numerical data in said processor; memory means for storing first n-digit numerical data put in by said input means; reading means for reading out said stored first n-digit data from said memory means and processing means for arranging said first n-digit numerical data read out by said reading means and second m-digit numerical data newly put in by said input means in neighboring relation thereby forming a new n+m-digit numerical data therefrom.

Input processor

Electronic data processing equipment such as an electronic computer is provided which is capable of specifying the radix or unit of input numerical data entered together with the radix or unit information manually keyed-in or automatically identified even without receiving such information. A number expressed in one radix or unit is converted into a number expressed in another radix or unit so that the arithmetic operations between the numbers expressed in different radices or units will be executed in a common radix or unit. The result may be displayed in either one of the radices or units.

Calculator capable of calculating with additional externally instructed

A calculator which adds or subtracts input numerical data to or from the content of a first register in response to an actuation of an addition or subtraction key, stores the result of the addition or subtraction in the first register, further adds or subtracts the above-mentioned input numerical data to or from the content of a second register determined by the number of actuations of the addition or subtraction key, and stores the result of the latter addition or subtraction into the second register.

Calculator for cross summing a plurality of operands

An electronic instrument having an operation count function for executing addition and subtraction. This instrument is provided with an item count register for storing the number of times of the operation of an addition instructing key or a subtraction instructing key, a total register for storing the result of the addition or the subtraction by the operation of said keys, a key for causing the content of said item count register and the content of said total register to be saved into other registers which are not used for the operation, and a key for causing said saved contents to be returned to said item count register and said total register, respectively.

Electronic instrument having an operation count function

The present invention provides an electronic apparatus for providing plural information, capable of displaying, while the addition or subtraction key is depressed, the item count indicating the number of actuations of the addition or subtraction key, and displaying the result of calculation obtained up to such key actuation when the key is released from the depressed state.
