Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an endoscope device in which the operations of various devices constituting a system are controlled by a microcomputer.

[0002]

2. Description of the Related Art Off-the-shelf video tape recorders (VTRs)
When a hard copy device or the like is used as a peripheral device of a system of an endoscope apparatus and its operation is controlled by a microcomputer, conventionally, software and hardware for that purpose have been incorporated in the microcomputer built into the system body.

[0003]

When the type of peripheral equipment connected to the system is to be changed, it is often necessary to change the software of the microcomputer and sometimes the hardware.

In such a case, in the conventional endoscope apparatus,
RO of the microcomputer built in the system body
Since the program itself stored in M (read-only memory) must be changed, and even the built-in hardware must be changed in some cases, the replacement work becomes a large scale, resulting in a very high replacement cost. In addition, it is very difficult to frequently replace and support various types of equipment.

Therefore, in addition to the ROM in the system body, only the program for controlling the operation of the peripheral devices by the microcomputer is stored in another ROM, and the circuit board (hereinafter referred to as "sub-device") to which the ROM is attached is stored. substrate"
It is conceivable that the above) is detachably attached to the system body.

However, among the processes by the program stored in the ROM of the sub-board as described above, there is a process partially common to the process by the program stored in the ROM in the system main body.

Then, when the processing contents of the common part are changed, the ROM of the system main body and the RO of the sub-board are changed.
Since both M have to be exchanged, it is very uneconomical because the process content is changed, and the labor and cost are overlapped.

Further, if only one of the ROM in the system main body and the ROM in the sub-board is replaced, the processing content will be inconsistent, so which version of the ROM in the system main body is affected by which sub-program. It is necessary to manage whether or not the ROM of the board can be linked, and the ROM management becomes very complicated.

The above-mentioned inconvenience is caused when a plurality of sub-boards are provided and there is a common processing content between the processings by the programs stored in the ROMs on the plurality of sub-boards.
The same happens.

Therefore, according to the present invention, the contents of the processing by the program stored in the ROM of the circuit board which is detachable from the system main body are the contents of the processing by the program stored in the ROM in the system main body and other circuit boards. It is an object of the present invention to provide an endoscope apparatus that can easily change the common processing content and easily perform the ROM management when there is a portion common to the content of the processing by the ROM.

[0011]

In order to achieve the above object, the endoscope apparatus of the present invention stores a program for controlling the operation of at least a part of various apparatuses constituting the system in a ROM in the main body of the system. In an endoscope apparatus having a microcomputer stored in, a circuit board having a ROM in which, in addition to the ROM in the system body, a program for controlling the operation of peripheral devices of the system by the microcomputer is stored. , The system main body is detachably provided, and a common processing content is provided in the system main body by the program stored in the ROM of the system main body and the program stored in the ROM of the circuit board. Stored in a specific address in the ROM of the Processing when performing the a, characterized in that the specific address of the ROM in the system unit and to perform reading and executing processing said common processing content.

Further, the endoscope apparatus of the present invention is an endoscope apparatus having a microcomputer in which a program for controlling the operation of at least a part of various apparatuses constituting the system is stored in a ROM in the system body. Separately from the ROM in the system body, a plurality of circuit boards having a ROM storing a program for controlling the operation of the peripheral devices of the system by the microcomputer are detachably provided in the system body. At the same time, among the processes by the programs stored in the ROMs of the plurality of circuit boards, the processing content common to each circuit board is stored in the specific address of the ROM in the system body and stored in the ROM of the circuit board. When performing the processing according to the program, start from the specified address of the ROM in the system main unit Characterized in that to perform the execution process reads the physical contents.

36-S39).

As described above, the freeze switch among them switches between on and off each time it is pressed. On the screen of the monitor 22, the main screen of the moving image is normally displayed as shown in FIG. 12, and when frozen, the moving image is displayed as a small sub-screen next to the main screen of the still image as shown in FIG. To switch.

FIG. 11 is a flow chart of the freeze processing S36, in which the state of the freeze switch is determined (S36).
1), processing f11, f13, f15 corresponding to the state
Alternatively, f12, f14, and f16 are performed (S362, S
363).

The processes f11 to f16 are processes (functions) common to the main process and the sub-substrate process, and are for the following processes, for example. f11 Main screen is a still image, f12 Main screen is a moving image, f13 Sub screen (video) is displayed, f14 Sub screen is erased (display is stopped), f15 Sub screen position is erased, f16 Sub screen Display the character at the screen position.

In the main processing, these f11 to f16 are
When the processing of 1 is used, these are called and used as a function or a subroutine (for example, as "call f11") in the same manner as the normal usage.

FIG. 15 is a flow chart of a sub-substrate processing program stored in the sub-substrate processing ROM 55 on the second sub-substrate 52. In S51, the state of the hard copy device 62 is input, and in S52. After performing processing for that state such as displaying "Busy" on the screen of the monitor 22 during hard copy, in S53, it is determined whether or not the copy switch in the panel switch 21 is turned on. judge.

In this judgment, for example, when the variable vc is "1", the copy switch is on, and when the variable vc is "0", the copy switch is off (S in FIG. 10).
33 and S37).

If the copy switch is not turned on, the process is ended as it is, and when the copy switch is turned on, S5
After performing the processing for making a hard copy in step 4, the variable v
The value c is set to "0", which means that the copy switch is off, and the processing is ended.

FIG. 16 is a flow chart showing the details of the hard copy processing S54. First, when the hard copy device 62 outputs a copy in S541, even if the copy switch is pressed using the function f23 in S542. It will end with a warning sound indicating that it was invalid.

If copy output is not being performed in S541, S
At 543, the peripheral device display in the lower right part is erased from the screen of the monitor 22 using the function f21. Then, in S544, it is determined whether the screen of the monitor 22 is frozen.

When the monitor 22 screen is frozen, S
At 545, first, the function f14 is used to erase the subscreen in the screen shown in FIG. 13, and then the function f16 is used to display a comment at the position where the subscreen was. As a result, the monitor 22 screen becomes a hard copy capture screen as shown in FIG.

Therefore, the monitor 2 is sent to the hard copy device 62.
Instruct to capture two screen images. The hard copy device 62 usually takes several hundredths of seconds to several tens of seconds to capture an image, so wait for that time and wait until the hardcopy device 62 completes capturing the image. , The function f15 is used to erase the character at the sub-screen position from the monitor 22, and the function f13 is used to display the sub-picture on the monitor 22.

Then, in step S546, the function f22 is used.
The peripheral device is displayed on the lower right part of the monitor 22 screen. As a result, the screen of the monitor 22 returns to the initial state shown in FIG. And finally, the hard copy device 62
To print out the captured image and end.

In S544, when the monitor 22 screen is displaying a moving image, that is, when the monitor 22 is not frozen, S
At 547, the function f11 is used first to change the main screen in the monitor 22 into a still image. As a result, the monitor 22 screen becomes the hard copy image capturing screen shown in FIG.

Then, the monitor 2 is sent to the hard copy device 62.
After instructing to capture images of two screens and waiting for time, when the hard copy device 62 completes capturing of images, the main screen in the monitor 22 is returned to a moving image using the function f12, and the process proceeds to S546.

Such functions f11 to f16 and f2 used in the hard copy processing S54 during the processing of the sub-board.
1 to f23 are common to those used in the main processing.
However, when these processes (functions) are used in the sub-substrate processing, even if "call f11" is instructed as usual, the program in the sub-substrate processing ROM 55 is the program in the main processing ROM 33. And is independent on the link,
Since the process f11 does not exist anywhere in the program on the sub-board processing ROM 55 side, the function f11 cannot be called.

Therefore, for example, the register bx of the CPU 31
And si, bx is set to the head address Y ₆₅ of the function table shown in FIG. 8, si is set to the function number (the number of bytes from the Y ₆₅ address) shown in FIG. ca
11 [bx + si] ”.

Since this instruction means that the address of the content of the memory address indicated by the register bx + si is called as a subroutine, the address of the content of the memory address indicated by bx + si has no relation to the program in the sub-board processing ROM 55. Also, the address is called.

Therefore, for example, bx is Y ₆₅ and si is 2
Assuming that bx + si points to the address in which the function f11 of the function table is stored and the content of the memory address is set to the head address of the function f11, “cal
l [bx + si] ”, the function f1
1 is called and executed.

In this way, the common processing used for both the main processing and the sub-substrate processing is stored only in the main processing ROM 33, and during the sub-substrate processing, the processing is stored in the main processing ROM 33.
For example, the following advantages can be obtained by calling from and using.

That is, when the position of the sub-screen displayed at the time of freezing is changed from the upper right position to the lower right position of the monitor 22 screen due to certain circumstances, the program in the main processing ROM 33 changes the functions f13 to f16. Is changed. However, since the program of the sub-board processing ROM 55 on the sub-board 52 calls and uses these functions f13 to f16, it is not necessary to change the program.

The present invention is not limited to the above embodiment, and for example, the function table associated with the main processing ROM 33 may not be provided. In this case, for example as shown in FIG. 17, stores the function f10, f11, f12 ... itself for common processing from Y address ₆₇ of the main processing ROM 33. The start address of each function should be clarified, and the start address of each function should not be changed even when the program is changed.

With this arrangement, when these functions are used in the sub-board processing, the head address Y of the main processing ROM 33 storing the function to be used is set to "call".
You can call it as "Y".

Further, according to the present invention, a plurality of sub substrates 51, 5 are provided.
The processes commonly used by the programs stored in the sub-substrate processing ROMs 54, 55, 56 on the Nos. 2, 53 may be stored only in the main processing ROM 33 in the same manner as described above. Also, when changing the common processing part,
Only the program in the main processing ROM 33 needs to be changed.

[0070]

According to the endoscope apparatus of the present invention, the processing by the program stored in the ROM in the system body and the processing by the program stored in the ROM of the circuit board detachable from the system body are common. The processing is stored in a specific address of the ROM in the system main body, or the common processing content among the processes stored in the ROMs of the plurality of circuit boards is stored in the specific address of the ROM in the main body of the system, When performing the processing according to the program stored in the ROM of the circuit board, the common processing content is read from the specific address of the ROM in the system main body, so when changing the common processing content, the system main body is changed. Internal ROM
You only have to change the program of the ROM of the circuit board
The program does not need to be changed at all.

Therefore, the common processing can be changed very easily, and no special condition is generated for the combination of the ROM in the system body and the ROM in the circuit board, so that the ROM can be easily managed for a long period of time.
