`ABSTRACT
`
`A facsimile apparatus having a scanner for reading original
`images, a memory for storing images, a printer for recording
`images, and a communication control section for controlling
`the transmissionlreception of data with a receiving commu-
`nication apparatus is connected to a host computer via a
`small computer system interface (SCSI). As a result, the
`scanner, the memory, the printer and the communication
`control apparatus provided in the facsimile apparatus can be
`controlled from the host computer. Data can be transferred
`between the host computer and the facsimile apparatus at a
`higher speed, and the scanner, the memory, the printer and
`the communication control apparatus can be effectively
`controlled from the host computer. Thus, various kinds of
`applications can be realized.

`facsimile apparatus by means of a host computer. Conven-
`tional RS-232C and GPIB interfaces are used therein as
`
`interfacing techniques for connecting the facsimile appara-
`tus to the host computer.
`there are
`However,
`in the above-described prior art,
`operational problems in that there is a limitation on the data
`transfer speed because interface techniques, such as
`RS-232C or GPIB, are used, and that it takes too much time
`to transfer images.
`In addition, there is a drawback in that, since there is a
`limitation on the data transfer speed, the host computer
`cannot realize various kinds of applications by controlling
`the scanner, printer, memory, line control section or the like
`provided in the facsimile apparatus.
`SUMMARY OF THE INVENTION
`
`The present invention has been achieved to solve the
`above-mentioned problems of the prior art.
`.
`An object of the present invention is to provide a facsimfle
`apparatus which is capable of increasing the speed at which
`data is transferred between a host computer and a facsimile
`apparatus and of effectively utilizing a scanner, printer,
`memory, line control section or the like provided in the
`facsimile apparatus by instructions from the host computer
`by using the small computer system interface (SCSI) for
`interfacing a host computer with a facsimile apparatus. This
`is a conventional interface whose description is published,
`for example by the American National Standards Institute at
`ANSI X1131-1986.
`
`Another objectof the present invention is to provide a
`facsimile apparatus which is capable of storing images read
`by the image reading section of the facsimile apparatus as
`files in the host computer and capable of controlling the
`transmission and recording thereof upon instructions from
`the host computer.
`A further object of the present invention is to provide a
`facsimile apparatus which is capable of entering images
`from a host computer into the memory of the facsimile
`apparatus and is capable of controlling the transmission and
`recording of the entered images under instructions from the
`host computer.
`A still further object of the present invention is to provide
`a facsimile apparatus in which a host computer, connected to
`a facsimile apparatus, which is capable of controlling the
`facsimile apparatus, obtains information on the apparatus
`with which it communicates from said facsimile apparatus
`and thereafter instructs the facsimile apparatus to transmit or
`receive images.

`FIG. 1 is a block diagram illustrating the entire construc-
`tion of a facsimile apparatus (hereinafter referred to as an
`apparatus) according to an embodiment of the present inven-
`tion. In this figure, a CPU 1 controls the entire apparatus in
`accordance with control programs stored in a ROM 2. Work
`areas and control data are temporarily stored in a RAM 3. An
`image memory 4 is a memory through which image data is
`handled. An image conversion section 5 converts resolution,
`paper size, and an encoding method.
`In this apparatus, an original document (image) is read by
`an image reading section such as a scanner 6 and printed out
`by an image recording section such as a printer 7. Commu-
`nication protocols between this apparatus and a communi-
`cation network are controlled by a line control section 8.
`Communication protocols between this apparatus and a host
`computer 15 are controlled by an interface section 9 with a
`host computer. In the present invention, a small computer
`system interface (SCSI) is used as an interface. SCSI is an
`interface by which data can be transferred at a speed higher
`than that by RS-232C or GPIB.
`Afile management section 10 manages documents created
`inside a facsimile apparatus, and the documents are stored in
`a storage apparatus 11. Operations of the facsimile apparatus
`are performed by an operation section 12. The line control
`section 8 is connected by a dedicated cable 13 to the
`network, and the interface section 9 with a host computer is
`connected by a dedicated cable 14 to the host computer 15.
`A detailed explanation will now be given about the
`control of a facsimile apparatus according to this embodi-
`ment. Since operations, such as transmission, reception, or
`copying, and methods employed in a facsimile apparatus,
`are well known, the explanation thereof is omitted here.
`Thus, only the control of this apparatus from outside via
`the interface 9 with a host computer will be described below
`in detail.
`
`FIG. 2 illustrates an example in which logic units are
`assigned to the blocks which constitute the facsimile appa-
`ratus. In this figure, an entire logic unit 21 is a unit in which
`the entire facsimile apparatus is considered as one unit. In a
`scanner 22, a printer 23, an image memory 24, and a line unit
`25, a logic ID (LUN: logic unit number) is set thereto with
`reference to a scanner section, a printer section, an image
`memory section, and a line control section respectively
`which comprise a functional block. In this embodiment, a
`specific command is set to each of these units so that the
`functions of each unit are utilized to their fullest and the
`
`burden on the host computer 15 is minimized.
`Next, functions provided in the units will be described
`unit by unit.
`FIG. 3 is a flowchart which illustrates the outline of
`
`processing commands inputted from an interface 9 with a
`host computer. The CPU 1 processes commands in accor-
`dance with this flowchart. In this figure, in steps S301 to
`S305, a check is made, for example from the LUN,
`to
`determine to which unit a command is issued. In steps S307
`to S311, a command process for each unit is performed on
`the basis of the determination results of steps S301 to S305,
`respectively. Step S306 concerns a step for a case in which
`invalid commands, such as undefined commands, are input,
`but this step is basically not performed.
`
`<Entire Logic Unit Command Processing>
`FIG. 4 is a flowchart which illustrates in detail operations
`for processing an entire logic unit command in step S307
`shown in FIG. 3.

`
`(Processing of Reserve Unit Command)
`The reserve unit command is a command which should be
`issued first when the facsimile apparatus is controlled by the
`
`65
`
`4
`host computer 15 so as to fully use the functions of the
`facsimile apparatus. The facsimile apparatus, upon reception
`of this command, checks the internal operating state or the
`like, and notifies the facsimile apparatus of any change in
`status depending upon whether the facsimile apparatus can
`follow the control by the host computer 15 from this time on.
`In this embodiment, after the reserve unit command is
`processed normally, it is called an “On-Line” mode. In the
`On-Line mode, processing of commands from the host
`computer takes precedence over operations from the opera-
`tion section 12. To explain more specifically, when it is
`determined in step S401 shown in FIG. 4 that the command
`is a reserve unit command, the internal state of the facsimile
`apparatus is checked in step S410. If the facsimile apparatus
`is not in a state in which various kinds of control commands
`from the host computer 15 can be executed, a confirmation
`of this status is sent out in step S413 (a check condition
`status is sent out on the basis of SCSI protocols). When the
`confirmation of the status is sent out, the cause thereof can
`be determined when the host computer 15 issues an infor-
`mation request command.
`When the result of internal status check is “OK” in step
`S410, the facsimile apparatus shifts to the On-Line mode,
`and an operation for displaying the status on the operation
`section 12 is performed, and the setting of internal control
`status is performed. In the subsequent step S412, an opera-
`tion for sending ‘out a confirmation of a normal status
`indicating that the reserve unit command processing has
`been terminated normally is performed (a good status on the
`basis of SCSI protocols is sent out).
`
`(Processing of Release Unit Command)
`This command is used to shift from the state in which the
`facsimile apparatus is placed in the On-Line mode by the
`reserve unit and processing commands from the host com-
`puter 15 takes precedence over operations from the opera-
`tion section 12 to the Off-Line mode in which the facsimile
`apparatus is operated as an ordinary facsimile apparatus.
`When it is determined in step S402 that the command is
`a release command, an operation for shifting to the O1f—Li.ue
`mode is performed in step S420. When the command from
`the host computer 15 is being executed, the execution is
`stopped, the internal stat
