PROBLEM TO BE SOLVED: To provide an observation device which can be mounted on instruments when the instruments are used and which can perform observation simultaneously with processing or operation. SOLUTION: This device is equipped with an optical lens 7 capable of moving between a reflection mirror 11 and an imaging device 2, and obtains an enlarged image from an observation surface S through the mirror 11. While an observation area on the surface S is kept in a focused state, the lens 7 can be changed in a tilt direction. Then, the device is equipped with a focusing lever 9 supporting the lens 7 to turn in the tilt direction so that the lens 7 is moved in an optical axis direction, and the mirror 11 is supported to turn in the tilt direction and turned interlocked with the lever 9. The lever 9 is provided with an engaging part 9b supporting the mirror 11 while sliding in contact with one end side of the mirror 11, and the mirror 11 elastically contacts with the engaging part 9b. |
