ABSTRACT:
In a pick-up unit, a tube base for a camera tube is integrated with a coil former having a system of coils. As a result, the length of the pickup unit is small so that it is possible to manufacture portable cameras of small dimensions. The radial position of the tube with respect to the coil former is fixed by centering means provided in the tube base and in a sealing cap engaging the coil former. The axial position of the tube relative to the coil former is fixed by urging the tube against an abutting face of the sealing cap by means of a spring. The coil former is surrounded by a .mu.-metal screening sleeve consisting of two portions. The two portions of the screening sleeve are coupled together by means of a clamping ring.
