Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating device used for, for example, writing data to a computer, and in particular, the present invention relates to an operating device having a single operating section,
It relates to a computer operating device that selects and operates multiple computers connected to it.

Generally, operations such as writing data to a computer are performed using a dedicated operation unit installed in each computer.
It would be reasonable and economical to be able to selectively operate multiple computers using a single operating unit. However, in order to achieve this, it is necessary to use a method such as changing the connection between the operation unit and each computer using connecting parts such as connectors.
However, this has the serious drawback that the power supply is temporarily cut off.

The present invention provides a computer operating device that allows you to selectively operate multiple computers by operating keys on a single operating unit to specify an operation target, without relying on methods such as changing connector connections. The purpose is to streamline computer systems.

The present invention will be specifically described below based on embodiments shown in the drawings.

FIG. 1 shows a computer operating device according to the present invention, in which a single operating section 4 has central processing units 10, 20, .
30 (hereinafter referred to as CPU) and panel controller 5
Although this is an example in which three computers 1.2.3 including .

As shown in FIG. 2, the operation unit 4 includes a key 41 for starting a computer specification operation, and number information and memory (not shown) for specifying a computer to be operated.
Data input key-4 for inputting write data, etc.
2, a set key 43 for confirming input, a display section 44 for displaying number information, a key 45 for starting the memory address setting operation, and a key 46 for starting the data writing operation to the memory. , a display section 47 for displaying setting addresses and write data, and the specified operation key 41, data input key 42, set key 43, and display section 44 are used to perform the specified operation of the operation target. The means for specifying the information to be provided is configured.

Each of the computers 1, 2.3 mentioned above is CPtJlo, 2
It has a panel controller 5 that controls the flow of data between the 0.30 and the operation section 4. The panel controller 5 is a register 5 for temporarily docking key human power.
3. It includes circuits such as a determining means for determining whether the computer specified by the operation unit 4 is the own computer, and a display register 54 for temporarily docking display data from the CPU.

The determining means is composed of a setting section 51 that retains number information assigned to itself, and a determining circuit 52 that determines whether the retained information matches or does not match the designated number information.

FIG. 4 shows the internal structure of the operating section 4 and the flow of signals and data in each structure, FIG. 5 shows the waveform of each signal, and FIG. 6 shows the control flow regarding designation of the operation target.

For example, assume that the first computer 1 is specified. First, when the specified operation key 41 is pressed (step 72 in FIG. 6), the key data KD is transferred to the computer 1.2.3 via the key manual register 53 of each panel controller 5.
sent to. As a result, each CPU10, 20, 30
is determined to be the next input data or number information specifying the computer, and the panel controller 5 sends the display request signal DR1°I) shown in FIG. 5 (1) to (3).
R2 and DR3 are output. In this state, each CPU10
, 20.30 is now ready to accept key personnel. Next, by pressing the data key 42 and inputting the number information (for example, number 1) of the specified computer (step 73 in FIG. 6), each CPUI'0, 20.3
0 outputs display data, and the display section 44 displays 01'''
is displayed (step 74 in FIG. 6). In this case, the operation unit 4 receives the display request signal DR1°DR.
2, DR3, the display enable signals DE, , DE2. shown in FIG. 5 (4) to (6) are generated. A display selection circuit 6 is provided which outputs the display enable signals DE1 . DE2. By inputting DE3 to the display register 54 of the panel controller 5, the output of the register 54 is controlled, and therefore, at this stage, the display on the display section 44 is being executed by the three computers 1, 2.3.

After checking the display on the display section 44, press the set key 43 (
At step 75 in FIG. 6, the determination means of each panel controller 5 determines whether it has received the designation. That is, each determination circuit 5 of the second and third computers 2 and 3
2 determines that the number information held by the setting section 51 and the number information related to the designation do not match, and as a result, the transmission of the display request signals DR, DR3 is prohibited (step 78 in FIG. 6). This causes the display enable signal DE2.
When DE3 disappears, CPU 20.30 prohibits reception of key input (step 78 in FIG. 6). On the other hand, the determining means of the first computer 1 determines that the above-mentioned image information matches, and as a result, the display enable signal DE is selected from the display selection circuit 6 in a continuous state. Therefore, at this stage, the first computer 1 The computer 1 executes and maintains the display on the display section 44. In this way, only the CPUIQ can accept key human input and perform processing such as writing data to memory (step 77 in FIG. 6).

In FIG. 5, the reference numeral a indicates the input time of the specifying operation key 41, and the reference numeral 2 indicates the input time of the set key 43, and the reference numeral A means "specifying the operation target" and the reference symbol B indicates the "operation target". "The target has been determined." Further, in FIG. 6, step 71 indicates the initial state at the time of specified operation, and "D"
If the determination of “Is R (display request signal) sent?” is NO,
In other words, if your own computer is not specified,
The computer continues to be in a state in which key personnel are prohibited from accepting requests, forming a waiting state.

On the other hand, if step 71 is YES, that is, the own computer is sending out a display request signal, and if the computer operation is to be continued, step 7
If the determination in step 2 is NO and the process proceeds to step 77 to designate a new operation target, the determination in step 72 is YES.
Then, the process advances to step 73.

Next, assuming that data is to be written to the memory of the computer 1, first press the address setting key 45.
The PU 10 recognizes that the next input data is a memory address, and then inputs the address using the input key 42 and presses the set key 43, so that the determined address is displayed on the display section 47. When the data writing key 46 is pressed and the data to be written is input using the input key 42, this data is displayed on the display section 47, and when the set key 43 is subsequently pressed, the data is transferred to the specified address in the memory of the computer 1. written to.

The present invention is configured as described above (i.e., a plurality of computers are connected to a single operation section, and one of the computers is selected and used by operating the keys on the operation section, so that it is possible to change the connection of the connector, etc.). It has excellent effects such as being able to select an operation target very easily regardless of the method and rationalizing the computer system.
