Abstract
Abstract An image processing device for controlling data transfer includes an image scanner, an image printer, a facsimile control unit, bus lines for data transfer, a bidirectional parallel interface unit, and a main CPU in a housing. The device is connected to an external data processing device through the parallel interface unit. In addition to the functions which are obtained independent from the external data processing device, the image processing device realizes various kinds of functions by controlling the image scanner, the image printer facsimile control unit and the interface unit by the main CPU in response to commands from the data processing device. As a result, various kinds of image processing functions are carried out.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
130 words
An image processing device of multifunctional type comprising: a main control portion; a plurality of units for processing information, each of which is designated as an input unit or an output unit, includes an independent controller and operates independently of the others in response to corresponding instructions issued by said main control portion, said plurality of units being within a single housing; and a main memory which includes sectionalized areas for storing operational conditions of respective ones of said plurality of units and to which said main control portion has access so as to read data stored in said sectionalized areas corresponding to said plurality of units designated as input and output units and for providing said plurality of units with respective read data to operate independently of each other.
Claim 2
Dependent Claim
130 words
An image processing device of multifunctional type comprising: a main control portion; a plurality of units for processing information, each of which is designated as an input unit or an output unit, includes an independent controller and operates independently of the others in response to corresponding instructions issued by said main control portion, said plurality of units being within a single housing; and a main memory which includes sectionalized areas for storing operational conditions of respective ones of said plurality of units and to which said main control portion has access so as to read data stored in said sectionalized areas corresponding to said plurality of units designated as input and output units and for providing said plurality of units with respective read data to operate independently of each other.
Claim 3
Dependent Claim
60 words
An image processing device as claimed in claim 1, when powered on, initial setting of operational conditions for each of said plurality of units is carried out according to a predetermined program for the image processing device and values obtained through said initial setting are stored in said sectionalized areas of said main memory as initial values having their alternatives.
Claim 4
Dependent Claim
40 words
An image processing device as claimed in claim 4, further comprising an interface unit which is coupled to an external host computer, by which the respective operational conditions for said plurality of units as input and output units are designated.
Claim 5
Dependent Claim
137 words
An image processing device of multifunctional type comprising: a main control portion; a plurality of units for processing information, each of which is designated as an input unit or an output unit, includes an independent controller and operates independently of the other sin response to corresponding instructions issued by said main control portion, said plurality of units being within a single housing; an interface unit through which data is transferred to and from an external host computer to any of said plurality of units; and a memory including a table of I/O codes expressing predetermined combinations of said plurality of units as input and output units for transferring data therebetween, any two of said plurality of units and said host computer are designated as input and output units and actuated in accordance with a selected I/O code.
Claim 6
Dependent Claim
137 words
An image processing device of multifunctional type comprising: a main control portion; a plurality of units for processing information, each of which is designated as an input unit or an output unit, includes an independent controller and operates independently of the other sin response to corresponding instructions issued by said main control portion, said plurality of units being within a single housing; an interface unit through which data is transferred to and from an external host computer to any of said plurality of units; and a memory including a table of I/O codes expressing predetermined combinations of said plurality of units as input and output units for transferring data therebetween, any two of said plurality of units and said host computer are designated as input and output units and actuated in accordance with a selected I/O code.
Claim 7
Dependent Claim
41 words
The image processing device of claim 4, said selected I/O code provided by said host computer, said plurality of units thereafter actuated in response to corresponding data transferred from said host computer through said interface unit to said plurality of units.
Claim 8
Dependent Claim
20 words
The image processing device of claim 4, said selected I/O code provided by an operating panel of said single housing.
