Abstract: A front-loading mechanism of a videocassette recorder utilizing a reel motor as a power source is disclosed. A gear is formed integrally with a pinion of a reel motor. A lever is fixed on a base plate with a hinge so that a pulley and a gear are fixed integrally at one end portion and a sliding pin is fixed on the other end portion which is biased by a spring. Said sliding pin is slid along sliding surfaces provided on a function plate. And, a belt 23 is interconnected between said pulley and another pulley fixed on the rotating axis of a worm.

Abstract: A device for preventing twist of a connecting line for a temperature probe in a microwave range. An electromagnet which is automatically actuated according to a connecting rod being inserted into a jack is provided so that a steel piece of an activating lever is attracted thereto to result in a stopping pin of the activating lever being outwardly extruded from a fixing plate through an opening. A disk having a protrusion at its peripheral surface is mounted on a rotating axis of a synchronous motor in such a manner that the disk is repeatedly rotated, invertedly in its direction every time the protrusion is contacted with the stopping pin.
