As a result, one conversion table in the memory 32 is selected. Here, the endoscope 10 for lower digestive organs will be explained as an example.

The photographer inserts the endoscope 10 into the body cavity and performs observation,
After determining the area to be imaged, the endoscope IO is fixed. 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 track B indicated by the X mark in FIG. 1) with his finger, pen tip, or the like. The coordinate data of the designated point is supplied from the touch sensor 16 to the discrimination circuit 30. The zero discrimination circuit 30 uses this coordinate data as address data.

Part data is read from one conversion table in the memory 32 that has already been selected. In this case, the descending result IN! (De
DC representing Cending Co1on) becomes part data. If you also need the insertion distance (in this case, the distance from the anus) as data to be imprinted, in addition to the body part data, enter the number representing the distance (unit: lll11) from the numeric keypad 20. In the case of the developed view of the stomach shown in Figure 2(b), G representing the stomach (Gastro) is
, a GP 150 consisting of P representing the posterior wall (Posteria) and an insertion distance 150 from the mouth is imprinted.

The region data obtained in this way is supplied to the camera 12 as described above, displayed on the display section 40, and recorded on film together with the image inside the body cavity. An example of imprinting is shown in FIG. 4. FIG. 4 is an example of a photograph of the lower colon at a position 2EOmm from the anus.
