In response to a read instruction, the confidentiality of a data entry to be read from memory is determined by referencing the state of a confidentiality flag corresponding to that data entry. If the data entry is determined to be confidential, then specified codes of the data stored in the RAM are converted into different codes, i.e., the data entry is scrambled. The data entry is then displayed using the converted codes.

Electronic apparatuses capable of scrambling confidential data for display

An electronic apparatus includes: a display screen; a power supply switch; a memory for storing a plurality patterns of graphic data, select information indicating which graphic data is selected, and the number of times by which the power supply switch is operated; a controller responsive to the power supply switch being operated for controlling the display screen to display graphic data of a pattern specified by the select information; and a device for updating in accordance with a predetermined scheme the select information and the number of times of operation of the power supply switch, if the power supply switch is operated and the number of times of operation of the power supply switch satisfies predetermined conditions. For example, when the power supply switch is operated a predetermined times, a dialog screen for selecting the next pattern is displayed. The patterns may be divided into groups so that upon operating the power supply switch predetermined times, the next pattern of the group is selected, and ultimately the dialog for selecting the next group is displayed.

Electronic apparatuses which displays various graphic data at the time

A data processing device according to the present invention including memory device, input device, display device for repetitions processing of various kinds of statistic data in table form and having the capability of easily executing various kinds of statistic calculations.

Data processing device for use in statistic calculation

In a data processing device for processing table data, a memory is adapted for storing the table data lined up in matrix shape. The data of each of the table elements can be displayed with the line item name and the row item name in a display unit having a small number of lines so that the table data may have a corresponding identification for a row and a line.

Data processing device for processing and displaying table data

A time display device comprising: a key input unit; a display unit; a clock unit for timing the standard time; a city name memory unit storing city names of three figures; a time difference memory unit storing the time differences of individual cities; a city name call unit for displaying the city names in a listed form in the display unit; a city name selection unit for selecting one city name from those listed; a city time calculation unit for determining the time of the selected city name by calculations of the standard time and the time difference and for outputting the determined time to the display unit; and city name rearrangement unit for enabling a city name of high selection frequency to be preferentially called by storing the selected city name in the head of the city name memory unit.

Time display device

An electronic calculator apparatus includes a keyboard for inputting numerical and function data, a printer for printing out on a record medium a sequence of data input by the keys and calculation results related to the data, and a printer controller for determining the content and format of the data printed out. The printer controller has the capability of recognizing when two successive function keys are actuated, and instructs the printer to print out on the record medium two successive function symbols without any numerical data symbols therebetween corresponding to symbols on the successively actuated function keys. Accordingly, an operator may study the record medium and locate amended function input data in regions where two function symbols ar juxtaposed.

Printer controller

An integrated electronic device has table preparation and graph drawing capabilities. A memory receives numerical input data which is arranged in tabular rows and columns. The device sums the data in column or row sums and stores the sums. A graph drawing device is responsive to the data stored in memory and controls a printer to draw a graph based on the row or column sums. The graph drawing device may draw one of a plurality of different graph types selected by the user. The column sum or row sum information may thus be displayed in one of the plurality of graph types.
