FIG. 1 is a perspective view showing the configuration of the first embodiment. Endoscope 1 consisting of ride guide, image guide, etc.
A camera 12 is connected to the eyepiece of the camera 12, and an image inside the body cavity transmitted through the image guide is photographed. The camera 12 has a data display section for imprinting data, and can imprint data such as the name of the imaged part, the name of the patient, and the date of imaging together with the image. A light source unit 14 is connected to the endoscope 10 via a universal cord 15. A ride guide is disposed within the universal cord 15, and illumination light from the light source unit 14 is guided to the tip of the endoscope via the light guide. Further, a data input section 17 is connected to the light source unit 14, and input imprint data is supplied to a data display section in the camera 12 via the light source unit 14 and displayed. The data input section 17 has a touch sensor 16 . When a certain point on the touch sensor 16 is pressed with a finger, pen light, etc., coordinate data of that point is output. here,
The part into which the endoscope 10 is inserted is determined depending on the model. A sheet 18 is placed over the touch sensor 16 on which a schematic diagram of this part of the body cavity is preprinted. Although FIG. 1 shows an example of the sheet 18 on which the lower digestive organ is printed, depending on the model of the endoscope, for example, the upper digestive organ as shown in FIG. 2 a or the upper digestive organ shown in FIG. A sheet with a developed view of the stomach printed on it as shown is used. The data input section 16 also includes a numeric keypad 20.

A block diagram of the electric circuit of this embodiment is shown in FIG. The touch sensor 16 and numeric keypad 20 are connected to a discrimination circuit 30 within the light source unit 14. The light source unit 14 also has a memory 32.
is connected to the discrimination circuit 30. The memory 32 is a conversion table for converting the coordinate data input from the touch sensor 16 into part data representing the part name at that position on the schematic diagram, and is composed of a conversion table for each sheet. The output of the discrimination circuit 30 is sent to the transmission circuit 3
4 to the camera 12. camera 12
The input data is supplied to the display section 49 via the receiving circuit 36 and the display control circuit 38.

Next, the operation of this embodiment will be explained. As shown in FIG. 1, the seat 18 corresponds to the model of the endoscope 10.
After placing the button on the touch sensor 16, use the numeric keypad 20 to select the model of the endoscope 10 or seat 1.
Enter the type of schematic diagram printed in 8. As a result, one conversion table in the memory 32 is selected. Here, we will introduce endoscope 1 for lower digestive organs.
This will be explained using 0 as an example.

The photographer inserts the endoscope 10 into the body cavity, performs observation, determines the region to be photographed, and fixes the endoscope 10. Here, the region to be observed with the endoscope 10 is within the sheet 18 above the touch sensor 16. Then, the photographer points out the corresponding part on the sheet 18 (the descending colon indicated by the cross in FIG. 1) with his finger, pen tip, or the like. The touch sensor 16 supplies the coordinate data of the designated point to the discrimination circuit 30 . Discrimination circuit 3
0 reads part data from one conversion table in the memory 32 that has already been selected using this coordinate data as address data. In this case, DC representing the descending colon becomes the site data. If the insertion distance (in this case, the distance from the anus) is required in addition to the part data as data to be imprinted, then a number representing the distance (unit: mm) is input from the numeric keypad 20. Also, Figure 2b
In the case of the developed view of the stomach shown in , a GP 150 consisting of G representing the stomach (Gastro), P representing the posterior wall (Posteria), and the insertion distance from the mouth 150 is imprinted.

The region data obtained in this way is supplied to the camera 12 as described above, and is recorded on a film together with the image of the inside of the body cavity displayed on the display section 40. An example of imprinting is shown in FIG. Figure 4 is an example of a photograph taken of the lower colon at a position 250 mm from the anus.

As explained above, according to this embodiment, body part data can be easily input by simply indicating points on the schematic diagram. Therefore, there is no need to search for alphanumeric keys or memorize the abbreviations of parts.
This can lighten the burden on the photographer. In addition, we have a structure in which a sheet with a schematic diagram printed on it is placed over the touch sensor, so if the model of the endoscope you use changes and you need to change the schematic diagram, you can simply change the sheet, making it suitable for many applications. Easy to answer.
