PURPOSE:To enable overall adjustments of functions of an image tube from outside the housing, by providing small holes in the peripheral wall of the cylindrical housing for enabling operations of the regulating apparatus for the power source contained within the housing. CONSTITUTION:Several small holes 8 are previously provided in the peripheral wall of the housing 5. These holes 8 are disposed at the positions that will exactly oppose the regualting volume controls 4 at the time the image tube 1 and the driving power source 2 are contained in the housing 5. Therefore, the image tube assembly is arranged so that the same can be effectively and easily adjusted by operating the volume controls 4 through the small holes 8 from outside the housing. The small holes 8 can be sealed off with silicone rubber or the like after all adjustments are finished, and the sealing is preferable for preventing malfunction of the apparatus during its operation. |
