PURPOSE:To permit checking of input data with not only a still camera but a television monitor as well by displaying the data from a data input device on the plane optically the same as that of the image from an endoscope. CONSTITUTION:A still camera 16 and a television camera 17 are connected to an adapter 13 for photographing, and the data corresponding to keys 21a from a data input device 21 is displayed in a display device 23 via a signal line 22 on the plane optically the same as that of the image of an object 12. If with such constitution a reflecting mirror 25 is in the solid line position of the figure, the optical image and the data of the device 23 are displayed in a television monitor 19. If the mirror 25 is in the chain line position of the figure, the ones the same as those displayed in the monitor 19 are photographed with the camera 16. Thereby, the input data is checked with the monitor 19 as well, not only with the camera 16. |
