A power consumption control apparatus for an information processing apparatus having multi-tasking control which executes a plurality of information processing operations in parallel by time-divisionally switching a plurality of tasks in an arithmetic processing unit. The power consumption controlled apparatus detects an event where there are no information processing operations to be executed, sets the arithmetic processing unit to a power-saving mode in response to the event and immediately clears the power-saving mode set in the arithmetic processing unit in response to an interrupt signal from an input/output device. Alternatively, the power consumption control apparatus after detecting the event stops supply of a clock to the arithmetic processing unit or lowers a frequency of the clock in response to the event. Thereafter, the power consumption control apparatus immediately resumes supply of the clock to the arithmetic processing unit or raises the frequency of the clock in response to an interrupt signal from an input/output device.

Power consumption control system

A method and apparatus for determining at least one of a character and a destination therefor in accordance with a received signal representing at least one of a plurality of characters and at least one character corresponding to at least one of a plurality of languages. Likelihood values for at least one of plurality of characters and each of the languages are evaluated, and at least one of the plurality of characters and one of the character languages are selected in accordance with the evaluated likelihood values thereof.

Method and apparatus for determining character and character mode for

An information processing equipment providing easy operations of changing-over character species, and, in which characters can be entered without being conscious of the designation of a character mode. Signals entered from an input device are handled in conformity with all of a romaji (Roman character) input system, a kana (Japanese syllabary) input system and an alphanumeric input system. Results obtained with the respective input systems are all displayed in the predetermined part of a display screen. In the equipment, the character mode intended by a user is estimated as to the entered character string, and is automatically selected. In another aspect of performance, a controller determines whether or not a character mode likelihood decision unit and a character code translation unit are started, in accordance with the results of the comparisons between the key code string and the registered contents of a learning information buffer. The position of the entered key code string as corresponds to the length of the longest one of the key code strings is detected as a boundary position, the entered key code string is translated into character codes with the unit of the translation being a key code string which extends up to the detected boundary position, and the translated character codes are displayed.

Character inputting method allowing input of a plurality of different

Control is performed for each of the individual components in accordance with a table including information on clock control and power control of each component of an information processing apparatus. Clock supply is stopped or clock frequency is lowered immediately or after the lapse of a predetermined period of time since the component is brought into an unused condition. Supply of power is stopped immediately or after the lapse of a predetermined period of time. In this case, the predetermined period of time can be automatically adjusted by detecting the condition of access to the component.

A data processing apparatus has an input unit for entering operator data and commands, and a display unit for displaying a work area for data processing. The display unit opens a job menu window for displaying types of selectable jobs by icons at a center of a display screen when the operator needs to select a new job.

Menu presentation method and data processing apparatus

A document creating apparatus for creating and editing a document in which a plurality of different types of descriptive element data, such as text data, graph data, pattern data, image data and other data, coexist. Plural types of edit sections are provided in correspondence with the types of data to be handled. Various types of data are edited under coordination by selecting edit sections corresponding to the types of data, respectively, while maintaining the editing function of the editing section once selected and activated so that the editing section can be selected again without losing its editing function.

Window management apparatus for a document creating apparatus

The document edition unit includes region set apparatus for setting a size of the region to a size corresponding to the print output, region attribute set apparatus for setting attribute information, region information hold apparatus, and text re-determination apparatus. The text data edition unit includes text input control apparatus. The region information hold apparatus manages the size and position of the region set by the region set apparatus in the size and at the position corresponding to those of at the time of print output, and manages the attributes set by the region attribute set apparatus so as to correspond to them. The text input control apparatus controls the arrangement to the character string at the time of text input by referring to the region information whose position on the page is fixed. When the user makes the operation which changes the input region of the text, the text re-determination apparatus re-determines the arrangement of the texts inside the page in accordance with the region.

Document preparation apparatus having rearrangement apparatus for

A document producing apparatus comprises an input unit for inputting descriptive contents such as characters or figures which contstruct a document and a format which defines a sheet size of a paper sheet used, a sheet direction of portrait or landscape in which the sheet is to be used, and a layout of the descriptive contents in each page, a storage unit for storing therein the descriptive contents and the format inputted from the input unit, a display unit for selectively displaying the contents stored in the storage unit, and an in-document layout editing unit for displaying on the display unit a layout of a plurality of pages forming the document so that page information of the respective pages are partitioned in due order from a leading page and for every predetermined number of pages and are arranged in one display image, the page information including at least the sheet size and the sheet direction stored in the storage unit. The apparatus may further comprise a page editing unit for performing the editing for a desired page while referring to a display image displayed on the display unit.
