Embodiments of the present invention will be described below with reference to the drawings. (First Embodiment) FIGS. 1 to 7 relate to a first embodiment of the present invention, FIG. 1 shows an overall configuration of an ultrasonic diagnostic apparatus according to the first embodiment, and FIG. FIG. 3 shows an operation flow of the CPU in the ultrasonic image observation apparatus when the power is turned on, and FIG. 4 shows a data structure of the initialization file in the HDD. FIG. 5 shows a method of determining whether or not the initialization file can be read, FIG. 6 shows an operation flow of the CPU in the ultrasonic image observation apparatus according to the modification, and FIG. 7 returns to the factory initialization file. CPU with functions
2 shows an operation flow.

As shown in FIG. 1, an ultrasonic diagnostic apparatus 1 according to a first embodiment of the medical diagnostic apparatus of the present invention comprises an ultrasonic endoscope 2 and an ultrasonic image observation apparatus 3. This ultrasonic diagnostic apparatus 1 employs an ultrasonic image observing apparatus 3 which is partially different from the ultrasonic image observing apparatus 3 'in the conventional ultrasonic diagnostic apparatus 1' shown in FIG. That is,
In the ultrasonic image observation device 3 'of FIG.
And an ultrasonic image observation device 3 employing a ROM 32 instead of the ROM 20.

As shown in FIG. 2, an initialization file necessary for starting the apparatus is stored in a rewritable HDD 31 and a read-only ROM 32 as nonvolatile storage (recording) means in this embodiment. I have. It should be noted that the file stored in the HDD 31 may actually be a nonvolatile and rewritable storage means such as an ATA card or a compact flash (registered trademark) card having a flash memory or a PC card interface. .

The ROM 32 is read-only,
Although it is not possible for the user to rewrite, it is also possible to use a flash memory or the like that allows the user to rewrite. In this case, the initialization file stored in the HDD 31 can be stored in the ROM 32.

In the present embodiment, the CPU 19 includes:
Readability / impossibility determination means 3 for determining whether the initialization file in HDD 31 and ROM 32 is readable or not
3 is built in. The other configuration is the same as that of FIG. 15, and the same components are denoted by the same reference numerals.
The description is omitted.

First, the internal configuration of the ROM 32 and the HDD 31 in FIG. 2 will be described. In the storage area of the ROM 32, the first initialization file Org. ini 36 is recorded. This Org. The ini 36 file stores the minimum set values required for the ultrasonic diagnostic apparatus 1 to start. The Org. i
There is almost no possibility that the file of ni36 becomes unreadable.

Next, in the storage area of the HDD 31, a second initialization file, Init. ini37, a third initialization file, User. ini38 is recorded. Init. The file of ini37 is shipped from the factory,
Org. In which the minimum set values are stored. ini3
Since the values finely adjusted from 6 are stored in advance, and the writing operation to this file is considerably limited, for example, at the time of factory shipment, the possibility that this file becomes unreadable is sufficiently low.

User. Each time the user changes the setting while using the device, the changed setting value is written in the file ini38. In this case, initially, the Init. Init.ini file, and when the user changes the settings while using the device, Init. i
ni37 file is changed, and User. in
An i38 file is generated. And hereafter this U
ser. The startup settings are made in the .ini38 file, and when the file is further modified, a new U
ser. An ini38 file is generated. And the latest User. The settings at the time of startup are made in the file of the ini38.

User. Since the file of the INI 38 can be freely rewritten by the user, if the power is turned off during the writing operation, the file may be damaged (impossible to read). In preparation for such a case, in the present embodiment, the operation of the CPU 19 when the power is turned on is as shown in FIG.

In FIG. 3, first, step S0
1, the CPU 19 sets the User. The INI 38 is accessed to determine whether reading is possible or not (the determination method will be described later).

If it is determined that reading is possible, the process proceeds to step S03, and User. The setting value stored in the file of the ini 38 is read, and the read value is set to the initial setting data and the like in each block via the control lines 26 and 27, and the process proceeds to step S06.

On the other hand, if it is determined that reading is impossible,
Proceeding to step S02, the Init. in
The file i37 is accessed to determine readability / non-readability (by the readability / impossibility determination means 33) (the determination method will be described later).

If it is determined that reading is possible, the process proceeds to step S05, where Init. The setting values stored in the ini37 file are read, and the control lines 26 and 2 are read.
7, the read value is set in each block, and the flow advances to step S06.

If it is determined in step S02 that reading is impossible, the process proceeds to step S04. In this step S04, secure O
rg. The minimum set value required for startup stored in the file of the ini 36 is read, and the set value is set in each block via the control lines 26 and 27. In step S06, the monitor 17 indicates that the operation preparation is completed. Then, this processing flow ends.

First, as described with reference to FIG.
r. Init.ini file is read, and if the file cannot be read, Init.
Ini.37 file is read, and if this file cannot be read, the read-only Org. ini
36 is read to set the initial value data.
Even if the file of ini38 cannot be read,
Init. ini37, Org. By reading the file of the ini 36, the situation where the initial value data cannot be read is effectively prevented, and the ultrasonic diagnostic apparatus 1 is activated to perform ultrasonic diagnosis.

Next, the method of judging whether reading is possible or not described in FIG. 3 will be described with reference to FIGS. FIG.
it. ini37, User. The data structure of the ini 38 is shown. At the head of the file, a checksum data 42 calculated from the setting value data 41 such as setting data 1, setting data 2,... is stored.

FIG. 5 is an operation flow for judging whether the file is readable or not by the readable / non-ready determining means 33 of the CPU 19. In step S11, the CPU 1
9 first reads the checksum data 42 described with reference to FIG. 4 and uses this as the SUM1 in the RAM 21 (see FIG. 1).
To save.

In the next step S12, the CPU 19 first reads out all the set value data 41 described in FIG. 4 and stores it in the RAM 21, and then proceeds to the next step S13. In this step S13, the CPU 19 calculates a checksum from the data read in the previous step S12,
The calculation result is stored in the RAM 21 as SUM2, and the process proceeds to the next step S14.

In this step S14, the CPU 19
UM1 = SUM2? Is determined, and if they are equal, the process proceeds to the next step S15, the file is determined to be readable, and this processing ends. On the other hand, if SUM1 and SUM2 are not equal in the determination in step S14, the process proceeds to step S16, the file is determined to be unreadable, and the process ends.

With the above configuration and operation, the HDD
In most cases, it is possible to avoid that the ultrasonic diagnostic apparatus 1 cannot be started even if the initial value data file inside 31 is damaged.

Next, a modification of the first embodiment will be described. FIG. 6 shows an operation flow of the CPU 19 when the power is turned on in this modification. In the operation flow of FIG.
nit. ini37 and User. If the file of the ini 38 is damaged, it is left as it is, and the setting value changed by the user is not saved. FIG. 6 shows an operation of a modified example in which this point is improved.

When the power supply of the ultrasonic image observation device 3 is turned on, the CPU 1 is executed in the first step S21 as shown in FIG.
9 is User. INI38 files readable? Is determined, the process proceeds to step S25 if reading is possible, and to step S22 if reading is not possible. If the process has proceeded to step S25, User. ini
The value read from the file No. 38 is set in each block, and the process proceeds to step S26.

When the operation proceeds to step S22, the CPU 1
9 is Init. INI37 file readable? Is determined, and if reading is possible, step S24
If the reading is not possible, step S23 is performed.
Proceed to. If the process has proceeded to step S24, Init. in
i37 file copy to User. The file is created as an .ini file, and the process proceeds to step S25 described above.

If the process has proceeded to step S23, the ROM 3
2 Ori. Ini36 copy of file
it. The file is created inside the HDD 31 as a file of the ini 37, and further proceeds to the next step S24. Thereafter, steps S24 and S25 described above are executed, and the process proceeds to step S26. In step S26, the fact that the operation preparation is completed is displayed on the monitor 17, and this processing flow ends.

By performing such processing and adding a recovery processing when a file that cannot be read is found, the set values changed by operating the ultrasonic diagnostic apparatus 1 are not saved. Can be avoided. That is, the initialization file that cannot be read inside the HDD 31 can be automatically restored.

The ultrasonic diagnostic apparatus 1 has a function of factory setting. This is effective when the user wants to return the setting to the original state after performing the operation verification by changing various setting values. The CPU 19 having the function of performing the factory setting is effective. FIG. 7 shows the operation flow.

In FIG. 7, first, at step S31, the CP
U19 is Init. INI37 file readable? Is determined, and if reading is possible, step S3
The process proceeds to step S3, and if reading is not possible, the process proceeds to step S32. If the process has proceeded to step S32, the Org. ini.ini file.
created as a file of ini37 inside HDD 31,
Proceed to step S33.

In step S33, User. ini38
File is unconditionally deleted (discarded) and Ini
t. ini37 file copy to User. ini
38, and the process proceeds to step S34. In step S34, the CPU 19 executes a RESET instruction or the like and ends this processing (actually, after step S34, the operation shown in FIG. In step S25, each block in FIG. 1 is set).

By providing the function of the factory setting as described above, the user can easily return to the original initial setting value data of the factory setting even if the user changes to the desired initial setting value data. Thus, the usability for the user can be improved.

Conventionally, the HDD 31 is used for production at a factory.
User. ini 38, Init. i
After creating the file of ni37, it was necessary to assemble each part such as the HDD 31 and make each adjustment.
According to the present embodiment, after assembling the parts first, FIG.
It is possible to perform each adjustment by executing the function of the factory setting described in the above, and it is possible to simplify the manufacturing process and obtain an effect of leading to cost reduction. Note that the determination method of “Readable?” In steps S21, S22, and S31 in the description of FIGS. 6 and 7 is the same as the method of FIGS.

(Second Embodiment) FIG. 8 shows a second embodiment of the present invention.
1 shows an ultrasonic diagnostic apparatus 51 according to an embodiment. The ultrasonic diagnostic apparatus 51 shown in FIG. 8 is different from the ultrasonic diagnostic apparatus 1 of the first embodiment shown in FIG. 1 in that the HDD 31 is replaced with an HDD 52 having an internal configuration shown in FIG. An ultrasonic image observing device 55 (in place of the ultrasonic image observing device 3) to which an apparatus I / F unit 53 is added is employed. The external device interface unit 53 is connected to an external recording device 54. In the second embodiment, “record” and “Ba”
ckUP ”function has been added.

When “record” is operated from the console 22 by a user operation, the CPU 19 causes the frame memory 15 to operate.
Is read out and stored in the HDD 52. FIG. 9 shows the internal structure of the HDD 52.

A "Data" directory 56 is created in the HDD 52, and the above-mentioned image data is stored in the Data directory 56, for example, in the form of aaa. img, b
bbb. img ..., xxxx. It is recorded in a bitmap file 57 having a name such as img.

Further, if only the “recording” function is used,
Since the free space of the DD 52 becomes insufficient, “Bac
"kUP" function. When the “BackUP” function is operated from the console 22 by a user operation, a BackUP menu 61 shown in FIG. The BackUP menu 61 includes an image file name display section 62, a cursor 63 that can be moved and selected by the pointing device 23 in FIG. 8, and a “start button”.
64.

The image file name display section 62 displays only the image file names stored in the Data directory 56.
Is operated to move the cursor 63 to select an image file to be backed up in the image file name display section 62 (the selected image file is changed to a highlighted display or the like so that it can be seen that it has been selected).

When the selection of the image file is completed, the user operates the pointing device 23 to move the cursor 63
Is moved to the start button 64, and this is selected. Then, the selected image file is transferred from the HDD 52 to the external recording device 54 via the external device I / F unit 53 in the form of a BackUP.
(Moved). FIG. 11 illustrates the BackUP operation of the CPU 19 after the start button 64 is selected.
It is.

In FIG. 11, in the first step S41, the CPU 19 determines whether there is an image file to be backed up. If there is an image file, the process proceeds to the next step S42. If there is no, the process ends.

In step S42, the CPU 19 reads one of the image files actually selected in the image file name display section 62 from the HDD 52, and reads (the external device I / O).
A command to write the read data to the external recording device 54 (via the F unit 53) is executed, and the flow advances to step S43.

In step S43, the CPU 19 issues an instruction execution result inquiry command to the external recording device 54, and determines "copy succeeded" based on the response result from the external recording device 54. By this determination processing, if the determination result is No, that is, if the copy is not successful,
This processing is terminated on the assumption that "a failure has occurred in the external recording device 54".

Conversely, if the result of the determination is Yes, that is, if the copy has succeeded, the flow advances to the next step S44, where the image file whose copy has been completed is deleted from the HDD 52, and the flow returns again to step S41 where "there is an image file to be backed up. ?? "

Thereafter, the loop from step S41 to step S44 is repeatedly executed to execute all the BackUPs of the image file selected in the image file name display section 62. Finally, No is determined in step S41 and the BackUP is determined. Is completed.

In the above configuration, when a magneto-optical disk device (hereinafter referred to as an MO disk) or the like is used as a recording medium, it takes time to actually complete the writing process on the medium. However, even if a reply of "no abnormality" is returned, a write error may actually occur in the MO disk device thereafter.

In such a case, the CPU 19 obtains the error information in step S43 of the next loop.
There is image data deleted from D52. As a result, when backing up using an MO disk or the like in which a writing error occurs, image data may be lost.

In the present embodiment, there is provided an improvement measure which can prevent such loss of image data.
3 will be described below. FIG. 12 shows the internal configuration of the HDD 52 'of the modified example in which the improvement measures are taken, and FIG. 13 shows the BackUP operation of the CPU 19 in the modified example in which the measures are taken.

First, the HDD 52 'shown in FIG. 12 has a configuration in which a "BackUP" directory 66 is added as compared with FIG. A subdirectory 67 is further created below the subdirectory 67.
The date and time when the function was executed may be created as it is as a directory name.

Then, the image data 68 on which “BackUP” has been performed exists under the subdirectory 67. In FIG. 9 to FIG.
The image data on which “P” has been executed is completely erased from the HDD 52, whereas “Bac” in FIGS.
The image data subjected to “kUP” is greatly different in that it is moved from the Data directory 56 in the HDD 52 ′ to the BackUP directory 66.

By doing so, "BackUP"
The image data on which the operation was performed is "BackUP menu"
Although it is not displayed in FIG. 10 and appears to be erased from the HDD 52 ′, it actually exists in the BackUP directory 66, so that the data can be easily recovered due to an accident.

The HDD 52 'may be divided into a plurality of partitions, and the BackUP directory 66 may be arranged in another partition, or the BackUP directory 66 may be arranged inside the added HDD.

Next, FIG. 13 shows the CPU 19 which has taken an improvement measure.
3 shows a BackUP operation. Note that the description regarding FIG. 10 is the same in this example, and FIG. 13 shows the operation of the CPU after the “start button” 64 in FIG. 10 is selected. In FIG. 13, in the first step S51, the CPU 1
9 creates a subdirectory 67 under the BackUP directory 66. (If the subdirectory name is created based on the current date and time at this time as described above, recovery processing in the event of an accident is facilitated. ).

In the next step S52, the CPU 19
Determines whether there is an image file to be backed up? If Yes, the process proceeds to step S53, and if No, the process ends. In the step S53, the CPU 19
Reads out one of the image files actually selected in the image file name display section 62 from the HDD 52 'and executes a write command of the read data to the external recording device 54 (via the external device I / F 53). And step S54
Proceed to.

In step S54, the CPU 19
It issues an instruction execution result inquiry command to the external recording device 51, and determines "copy succeeded?" If the result of the determination is No, it is regarded that "a failure has occurred in the external recording device", and this processing ends.

Conversely, if the result of the determination is Yes, the flow advances to step S55 to copy the copied image file again.
The data is copied from the Data directory 56 of the HDD 52 'to a subdirectory 67 of the BackUP directory 66 created in step S51. Then, the process proceeds to step S56 to copy the image file copied to Dat.
a from the directory 56, and the process returns to step S5.
2 and determine whether there is an image file to be backed up?

Thereafter, the loop of steps S52 to S56 is repeatedly executed to execute all the BackUPs of the image file selected in the image file name display section 62. Finally, No is determined in step S52 and B
The ackUP process ends.

With the above-described configuration, even when the “write error notification delay” occurs due to the time required for the write processing to the medium described with reference to FIG. 11, an image for which “BackUP” has been completed is obtained. The data is "Ba
Since it exists in the “ckUP” directory, the image data is not lost, and the problem is improved.

When the above improvement measures are taken, the HDD 5
In the case of 2 ′, there is a concern that recording may not be possible due to insufficient capacity. This is because “the entire contents of the BackUP directory 66 are completely stored when the power is turned on for the first time after the appropriate date and time, such as 7 days. A function such as "automatically delete" is incorporated in the control program of the CPU 19, or "clear inside the spare HDD" as a user-selected function.
Such a function can be easily dealt with by such a method that the user periodically executes the function.
