In an imaging apparatus equipped with a flat cathode ray tube in which the cone portion 10 is fixed to the chassis 3 by first to third support members 50, 5, 51 provided on the chassis 3, the first to third support members 50, 5, 51 are provided. The supporting member 50 presses the tip of the cone section 10 from the front and back, the second support member 5 presses the cone section front wall 15 connecting the fluorescent screen panel 13 and the network tube 12, and the third support member 51 presses the front end of the cone section 10. A second support member is disposed at a position to press the back panel 14 at a position closer to the first support member 50 than the second support member 5, facing the back panel 14 disposed opposite the front panel 13. An imaging device equipped with a flat cathode ray tube, characterized in that the member 5 is equipped so that its fixing position can be adjusted in the direction in which it is pressed against the cone part 10. The imaging device according to claim 1, wherein the phosphor screen panel 13 is transparent and the image formed by the phosphor screen is observed through the phosphor screen panel 13. The imaging device according to claim 1, wherein the back panel 14 is transparent and allows the image on the phosphor screen panel 13 to be seen through and observed. The second support member 5 is fixed by screwing a screw 54 to the end of the support member through a long hole 36 formed in the chassis 3. The imaging device according to any one of claims 1 to 3, which is formed to be long and perpendicular to the utility model.
