Reference numerals 14 and 15 are a transmitting terminal and a receiving terminal, respectively, for performing remote transmission of the Centronics interface. The central control room 12 is provided, for example, in a reactor auxiliary building, and the computer room 11 is provided, for example, on a different floor from the central control room.
In position.

FIG. 2 is a block diagram showing details of the internal configuration of the hard copy apparatus 2 of FIG. 1 and connections with related devices. Note that FIG. 2 shows the hard copy device 2c on the most downstream side of the hard copy device of FIG. 1 as an example for convenience of description, but other hard copy devices 2a,
2b has exactly the same configuration. In FIG. 2, reference numerals 5 to 9 are the same as or equivalent to the same reference numerals shown in FIG. Reference numeral 16 denotes an input / output I / O of the upstream hard copy device, here, the hard copy device 2b.
Input I / F for inputting image information output from F unit 8
Parts, 17 selects the image input to any preceding the input image from the input image which is input through the image processing section 7 is read from the memory 6 I / F unit 16 input-output I /
A signal selection unit 18 to be sent to the F unit 8 is an external control unit that receives a control command from the host device 1 and sends it to the control unit 9.

The configuration of the connection between the hard copy apparatuses 2 will be described below with reference to FIGS. That is, first, the input / output I / F unit 8 of the most upstream hard copy device 2a and the input I / F unit 16 of the hard copy device 2b are connected, and then the input / output I / F unit of the hard copy device 2b is connected. 8 and the input I of the most downstream hard copy device 2c
/ F section 16 is connected. Then, the input / output I / F unit 8 of the most downstream hard copy device 2c is connected to the printer device 4. That is, instead of the conventional method of switching the connection by providing a multiplexer, a method of simply connecting a plurality of hard copy apparatuses 2a, 2b, and 2c in series in a chain and finally outputting the output to the printer apparatus 4. .

Next, the operation will be described with reference to the flowcharts of FIGS. In the central control room 12, the control operation is performed by each operator for each block of a, b, and c, and the image information necessary for each block is displayed on each display 3.
a, 3b, and 3c. Here, block c
If a hard copy request is made from the request panel 13c (S1), a hard copy request signal is transmitted from the request panel 13c to the host device 1c (S1).
2). Upon receiving the hard copy request signal (S3), the host device 1c stops updating the display on the display 3c (S4). Therefore, the display 3c continuously displays the screen for which the hard copy request has been made until the suspension of the update display is released in a later process. As a result, the operator can easily confirm the contents of the screen for which the hard copy has been requested, and the display screen is not disturbed due to an image capturing operation described later.

The host device 1c simultaneously transmits an image capture request signal to the hard copy device 2c (S
5). It should be noted that the image is taken in one screen unit. The image capturing request signal from the host device 1c is received by the external control unit 18 of the hard copy device 2c (S6), and the image capturing unit 5 is driven via the control unit 9 to start capturing a screen (S7). The fetched screen is similarly stored and stored in the memory 6 for each screen. When this operation is completed, the fact is transmitted to the host device 1c via the control unit 9 and the external control unit 18 (S8).

Next, moving to the flowchart of FIG. 4, the host device 1c, which has received the notification of the completion of the screen capture and storage, releases the stop of the update display up to that time. As a result, the display 3c displays image information according to the progress of the original control operation (S9). Then, the hard copy system is ready to receive a hard copy request from the next request panel 13c (S10).

On the other hand, in the hard copy device 2c, the screen read from the memory 6 is edited by the image processing unit 7 and input to the signal selection unit 17. Then, the signal selection unit 17
At this time, it is determined whether or not a screen signal has already been input from the input I / F unit 16 (S11). Input I /
When an input is made from the F unit 16 (YE in S11)
S) first outputs the screen signal to the input / output I / F unit 8 (S12). Here, the screen signal input from the input I / F unit 16 is the one-stage upstream hard copy device 2b
In some cases, the signal may be a signal captured by the hard copy device 2a on the most upstream side and input to the input I / F unit 16 of the hard copy device 2c via the hard copy device 2b.

The signal selecting section 17 outputs the screen signal from the input I / F section 16 and then outputs the screen signal to its own memory 6 and image processing section 7.
Is output to the input / output I / F unit 8 (S1).
3). However, at S11, when the screen signal from its own memory 6 and image processing unit 7 is input, the input I / F unit 1
If there is no screen signal from S6 (NO in S11), the process immediately proceeds to S13 and outputs the screen signal from its own memory 6 and image processing unit 7 to the input / output I / F unit 8. Input / output I / F
The unit 8 transmits the screen signal to the printer 4 via the Centronics I / F (S14). Here, the hard copy device 2c has been described as an example, but for example, in the case of the hard copy device 2a, the input / output I / F unit 8 is 1
The screen signal is transmitted to the input I / F unit 16 of the hard copy device 2b on the downstream side (S14).

The printer device 4 receives the sequentially transmitted screen signals and outputs a hard copy as a print display. Therefore, each operator in the central control room 12
Although there is a slight difference in response time depending on the presence or absence of a hard copy request from another request panel 13, if the user goes to the printer device 4, he or she can always obtain a hard copy output of the screen requested by the user. .

As described above, in this embodiment, the connection structure between the hard copy devices 2 and the printer device 4 becomes extremely simple, and only the connection between the hard copy devices 2 is required. It is short and economical. Further, even when the number of hard copy apparatuses 2 increases or decreases due to expansion or change of facilities, the input / output I / F section 8 and the input I / F section 1 of the adjacent hard copy apparatuses 2 are always present.
6, it is sufficient to connect all the units at that time in series in a chain, so that it is extremely simple to deal with these unit changes.

Embodiment 2 FIG. In the first embodiment, the hard copy request is received by the request panel 13, and this hard copy request signal is input to the host device 1 once to stop the update display on the display 3 and, at the same time, starts with image capture. Although a series of processing is performed, a print start switch dedicated to hard copy request is provided, and a hard copy request signal from this switch is directly input to the external control unit 18 (see FIG. 2) of the hard copy apparatus 2 and immediately. The image capturing operation may be started. There is an advantage that the configuration as an apparatus is simplified accordingly.

Embodiment 3 FIG. In the first embodiment, the image information is fetched, stored, and read out in units of one screen displayed on the display 3. However, depending on the content of the image information, it is performed in units of a specific plurality of screens. Alternatively, one screen may be further divided and a part thereof may be performed as a unit.

Embodiment 4 FIG. Further, the signal selection unit 17 of the first embodiment is configured to control the screen signal from the memory 6 and the input I / F unit 16.
When the screen signals from the coexistence are present, the output is started from the previously input signal. However, priorities are determined in advance for the plurality of hard copy devices 2 based on, for example, their importance. May be selected and output.

Embodiment 5 FIG. Further, in the first embodiment, the case where three sets of hard copy devices and the like are provided has been described. However, the present invention can be applied to any plural sets. Further, in the embodiment, the printer device 4 is constituted by one unit.
For example, a configuration may be adopted in which two units are used and the received signals are alternately subjected to reception processing to increase the processing capacity.
