Abstract: PURPOSE:To allow a plurality sets of contact to be opened and closed in order by means of a small-sized and inexpensive rubber sheet key switch. CONSTITUTION:Four sets of contacts 2a, 2b provided on a board 1 are covered with a rubber sheet 3 while conductors 4 are provided in the opposing positions to the contacts 2a, 2b of the rubber sheet 3 respectively. Then, key tops 8 provided on a seesaw type lever 6 press the conductors 4 on the contacts 2a, 2b in order to open and close the switches of two stages.

Abstract: PURPOSE:To prevent the generation of focus deviation at the time of reuse by providing a link bringing the focus changeover lever of the lens to the neutral position with a dustproof cover slided to the front of the lens. CONSTITUTION:Sliding a changeover lever upward from the standard neutral position, it becomes a wide angle state, and a link 45 is inclined shown by alternate long and short dash line. Accordingly, when a cover 9 is closed in this state, a collation part 48a is collated with a lower end 45a of the link 45, rotating the link 45 to the horizontal position shown by a solid line. A connection board 41, that is, a changeover lever 40 is returned to the neutral position, and a lens 7 is returned to the standard position. When sliding down the changeover lever 40 with the cover 9 opened, the link 45 is inclined in the opposite direction to become a telephoto lens state. When closing the cover 9 in this state, the collation part 48b is collated with the lower end 45b of the link 45, returning the link 45 to the horizontal state. Therefore, the changeover lever 40 is returned to the neutral position.

Abstract: PURPOSE:To save space by forming a hollow cylinder of light metal or its allow by extrusion molding, and cutting this cylinder into a frame of specific height. CONSTITUTION:The frame 15 made of Al alloy is interposed between a circuit board 16 and a mechanism chassis 17. The circuit board 16 is made of an insulating substrate and various circuit parts 18 are mounted to form a specific circuit. This circuit board 16 is coupled with a flame 15 by using screws 19. The screws 19 are screwed into grooves 12 formed at the corners of the frame 15. A rotary head drum 20 and a cassette holder 21 are fitted on the mechanism chassis 17 and coupled with the frame 15 with screws 22. Those screws 22 are also screwed into the grooves 12 of the frame 15. Consequently, the mechanism chassis 17 and mechanism frame 15 are both reduced in cost and also combined with each other to have large strength, so strength required for a VTR is secured.
