The present invention is directed to a television schedule guide which includes a detector for determining whether a previously scrambled program is unscrambled. The inner wall of the flange ring enables the collection of oil coming from the bearing and prevents the projection of oil onto a wall of the working container and permits the oil to drain to the bottom of the reservoir. A plurality of wheels are attached to the chassis adjacent the rear end, and a hitch assembly is attached to the chassis adjacent the front end. The second part of the lid is attached to the first part by means of a flexible strip and provides a cover which frictionally engages the lid first part. The grip member is applied with a force along the assembly direction or along a direction opposite to the assembly direction to engage or disengage the male and female fasteners.
