A television camera comprising a pickup lens and a pickup unit which is aligned with respect to the lens. The pickup unit is arranged in a holder with a slide. The pickup unit is displaceable on the slide along an axis in the direction of the pickup lens by means of an adjusting lever. This lever is resiliently clamped between the pickup unit and a wall of the holder which is directed transverse to the slide. One end of the lever is directly coupled to the transverse wall, while the other end is coupled thereto by way of an adjusting member. When the adjusting member is displaced, the lever is tilted around the point directly coupled to the holder. The center of the lever then moves the pickup unit over the slide. This construction is simple, does not require high manufacturing precision, and its operation is free of play and stickiness. |
