Abstract: The present invention is directed to a video signal switching apparatus having editing function to select an arbitrary video signal from plural video signals or carry out synthesis thereof, which allows an operation unit to be of modular configuration every respective functions to electrically connect adjacent modules of panel modules (22A to 22D) which serve as respective operation modules to each other by relay bases (23), (24) to carry out transmission of signals between both modules, and to allow connection between the panel modules (22A to 22D) and the relay bases (23), (24) to be connector connection to thereby have ability to freely change layout of the panel modules (22B to 22D) of division size in which 19 inches rack size is fundamental in accordance with fondness of operator.

Abstract: A switch mechanism of a detection sensor unmounted type has a configuration in which an attaching surface for a case body for containing a movable member moved in conjunction with a button operation and a mounting surface for a detection sensor operative to electrically detect a change in the position of the movable member attendant on the button operation are different, and a magnifying mechanism operative to magnifyingly transmit the change in the position of the movable member attendant on the button operation is mounted in the switch mechanism.

Abstract: An automatic cassette changer wherein a plurality of types of cassettes having different recording formats can be used. The automatic cassette changer comprises a plurality of types of cassettes in which different types of record media having different recording formats are accommodated, a cassette storage rack having a plurality of bins for storing the cassettes therein, a plurality of recording and/or reproducing apparatus each provided for selectively recording and/or reproducing a format signal in accordance with a selected one of the recording formats of the plurality of types of cassettes, and a transport mechanism for selectively transporting the cassettes between the bins and the recording and/or reproducing apparatus.

Abstract: A rotary head assembly is provided with a sweeper member upstream of a magnetic head with respect to the direction of feed of magnetic tape which serves to remove dust, grit and so forth from the tape surface. The aforementioned member is provided with a surface lying oblique to the tape axis so as to effectively scrape off the dust, grit and so forth.
