The operation of the data imprinting device 1 according to an embodiment of the present invention will be described below.

First, a procedure for inputting photographic data regarding a patient into the data imprinting device 1 will be described. At this time, it is assumed that the data imprinting device 1 and the light source device 59 are connected.

For example, it is assumed that the imaging data for patient 1, that is, in this embodiment, data regarding the date of imaging, the patient's initials, sex and age, and medical record number are input. These data are stored in the memory area M1- of the RAM 22 of the data imprint control circuit 19.
01, M2-01 and M3-01, first operate the "DATE" key. This "DATE"
When a key operation is detected, the CPU 42
is a light source device 59 connected to the data imprinting device 1
A date data request signal is generated to the light source control circuit 60 provided in the. The light source control circuit 60 is
The CPU 74 causes the date data to be read from the date data memory area of the RAM 64 that stores the date data from the clock circuit 66, stores this date data in the display buffer register BR1 of the RAM 22 of the data imprint control circuit 19, and displays it. unit 2
4 (monitor data display section 8). In this example, it is assumed that "821022" representing October 22, 1982 is displayed on the monitor data display section 8. This allows you to check whether this date data is correct. If the displayed date data represents the correct shooting date, press the "ENABLE" key and then "1 column".
When the key is operated, this shooting date data is stored in RAM2.
The date data is stored in the display buffer register BR2 of No. 2, and the date data is displayed on the display unit 25 of the photographic data display section 10.

Also, if the date data indicates an incorrect shooting date, after operating the "ENABLE" key,
In order to enter numerical data representing the correct photographing date into the display buffer register BR1, the numeric key operation is executed, and then the "1st column" key is operated. This will ensure that the correct date data is entered.

Next, enter data about the patient. When entering this data, the ``ENABLE'' key is operated again, and two alphanumeric keys are used to represent the patient's initials, e.g. ``M'' and ``Y'', the ``SPACE'' key is used to open a blank, and the ``SPACE'' key is used to represent the gender. keys, such as the "-" key, and two numeric keys representing age, such as the "2" and "4" keys, are operated in this order. This results in
For example, data "MY-24" is input to the display buffer register BR1. After this, when the "2nd column" key is operated, the contents of display buffer register BR1 are stored in display buffer register BR3,
It is displayed on the display unit 26 of the photographic data display section 10. In this case, the display buffer register
Data “MY-24” is stored in BR1,
It is displayed on the display unit 24 and its contents can be confirmed.

Next, operate the "ENABLE" key to input medical record data. Thereafter, data regarding the medical record number is written into the display buffer register BR1 by the same key operation as the previous time. For example, here it is assumed that medical record number data "A12345" has been entered in the display buffer register BR1. After this, when the "3rd row" key is operated, this data "A12345" will be displayed in the buffer register BR.
4 and displayed on the display unit 27 of the photographic data display section 10. Further, the contents can be confirmed on the display unit 24.

In this way, display buffer registers BR2, BR
3 and BR4 with shooting date data, initials,
Gender and age data and medical record number data are stored. These data are displayed on each display unit 2.
5, 26 and 27. After this, press the “ENABLE” key and then the patient key “1”.
When is operated, data "KO1" representing patient "1" is stored in display buffer register BR1 and displayed on display unit 24, and the contents of display buffer registers BR2, BR3 and BR4 are The data are stored in memory areas M1-01, M2-01, and M3-01 in the RAM 22 of the imprint control circuit 19, respectively.

The imaging data for patients 2 to 10 are also processed in the same way as described above, from memory area M1 to RAM 22.
02 to M3-02, M1-03 to M3-03... and M1-10 to M3-10. In this way, data regarding the patient scheduled to be diagnosed on that day can be stored in the data imprinting device 1.

Next, when starting endoscopic treatment, for example, if you want to record photographic data for a patient on film, attach the endoscopic camera to the camera attachment part 2 of the data copying device 1 body, and enter the patient key "1". Manipulate. As a result, data "K01" is read from the ROM 20 and stored in the display buffer register BR1, and the data "K01" is read out from the ROM 20 and stored in the display buffer register BR1.
The contents of M2-01 and M3-01 are transferred to display buffer registers BR2, BR3 and BR4 of RAM22. As a result, the monitor data display section 8
Data "K01" is displayed on the (display unit 24), and the data "K01" is displayed on the shooting data display section 10 (display unit 2).
5 to 27) The data regarding patient 1 shown in FIG. 9 will be displayed above. Before performing endoscopic imaging, patient data is imprinted by imaging one frame of the data film shown in FIG.

Next, the data imprinting operation during endoscopic imaging will be explained. At this time, the endoscope camera 106 that has captured the patient data is removed from the data capture device 1 and attached to the endoscope 105.

In this state, the endoscope camera 79 is connected to the data imprinting device 1 via the endoscope and the light source device 59, and the control function of the endoscope camera itself does not operate; It is controlled by a signal from the imprinting device 1.

First, operate the "FREE" key or "DATE" key. Here, for example, the former operation
After transferring the memory contents of the free data memory area of the RAM 22 to the display buffer register BR1 of the RAM 22 and displaying it on the display unit 24 (monitor data display section 8), operate the "ENABLE" key to enable data input. Set state. In this state, the numeric keys, alphanumeric keys, etc. are operated, and desired 6-digit imprint data is stored in the display buffer register BR1. After this,
When the "FREE" key is operated again, the contents of the display buffer register BR1 are stored in the free data memory area of the RAM 22, and the contents of the display buffer register BR1 are stored in the free data memory area of the RAM 22. It is also stored in the imprint memory area of the RAM 84 of the control circuit 80. The contents of the photographic memory area of the RAM 84 are displayed on a display unit 86 within the endoscope camera 79. If a photograph is taken in this state, the display data on the display unit 86 will be recorded together with the affected area on the film of the endoscopic camera.

By performing the above operations, the photographed film records photographic data 101 and an endoscopic image 102 as shown in FIG.

Also, if you do not want to record the display data on this display unit 86 when taking endoscopic images,
The data switch 90 may be operated before operating the camera release switch (not shown) or the "RELEASE" key on the keyboard. In response to the operation of this data switch 90, the CPU 98 supplies a prohibition signal to the display driver 88 to prohibit the display operation by the display unit 86. This prohibited state is canceled by operating the data switch 90 again.

Although the present invention has been described above with reference to one example,
The invention is not limited to this embodiment. For example, a buffer memory for time and date data is coupled to the clock circuit 66 separately from the RAM 22, so that when the supply of external power supply voltage is suddenly cut off, the clock circuit 66 continues to operate and retains the time and date data. It is possible to provide an internal power supply for this purpose. Also, data display section 1
0 uses a display unit with three columns, but it is also possible to use a display unit with two or four or more columns. Furthermore, in the above embodiment, RAM2
Although we explained that the shooting date data is stored in the memory areas M1-01 to M1-10 of 2, since this shooting date data is usually the same, instead of these memory areas, a single shooting date data is stored. It is also possible to use memory areas.

Further, although the display sections 8 and 10 have been described as being composed of LEDs, they can be composed of other display elements, such as liquid crystal displays. This display 10 is placed at a position facing the camera mounting part 2, but by using an optical system that guides the light from this display part 10 in the direction of the camera mounting part 2, this display part 10 can be moved to a different position. It is possible to provide the Furthermore, the clock circuit 66 may be coupled to the control circuit shown in FIG. 7, or the memory areas M1-01 to M1-10, M2-01 to M2-
It is also possible to allocate 10 and M3-01 to M3-10 in RAM 64. That is, the data imprinting device 1 according to the present invention includes a clock circuit 66 and
It should be understood that the above-mentioned memory area of RAM 22 is included.
