Abstract: A tape cassette loading system for wrapping a magnetic tape about a magnetic rotary head drum of a recording and/or reproducing apparatus is provided. The loading system includes two tape guiding elements for withdrawing the tape from a tape cassette towards the rotary head drum and their tape guiding track members provided around the drum in order to define a tape loading paths. One of the tape loading path slopes downwardly from a loading stand-by state position. The other tape loading path slopes upwardly from the loading stand-by state position. The movement of the two guiding elements traveling in their loading paths allows the tape to be wrapped helically about the drum. The height drum may therefore be reduced and the recording and/or reproducing apparatus can be made smaller.

Abstract: A cassette loading mechanism for loading a magnetic tape cassette, which has a front pivotal closure member openable for covering or exposing a front opening of the magnetic tape cassette, in a recording and/or reproducing apparatus includes a cassette holder which is movable between an eject position, at which the cassette can be inserted into or removed from the cassette holder, a lowered position vertically offset from the eject position, and a loaded position horizontally offset from said lowered position and at which cassette loading is completed. The upper portion of the cassette holder is covered with a cassette holder lid which has a recessed portion so that the front pivotal closure member may be moved to open in synchronism with movement of the cassette holder from the eject position to the lowered position. The cassette holder lid and the cassette holder are moved in unison.

Abstract: PROBLEM TO BE SOLVED: To provide a rotary head drum device having a video signal connection structure which gives no influence to the attaching of the rotor of a rotary transformer to a rotary head drum.
SOLUTION: A spring contact 50 is disposed through a terminal attaching plate 48 on the bottom surface of the rotor 41 of a rotary transformer attached to the top surface of a rotary drum head 20. On the other hand, a terminal attaching plate 35 having a head contact terminal 63 is attached to the portion of the lower side of the rotary head drum 20. A projected portion 60 in which the electrodes 64 of the head contact terminal 63 are positioned on both sides is disposed in the terminal attaching plate 35. When the rotary head drum device is assembled, the spring contact 50 and the electrodes 64 of the head contact terminal 63 establish conductivity to each other in the through-hole 39 of the rotary head drum 20.

Abstract: PROBLEM TO BE SOLVED: To simplify a structure and to reduce the number of assembling steps by uniting a tape cassette constituting a tape deck with a mechanism part for loading/unloading a tape cassette and traveling a tape to form an integral mechanism unit. SOLUTION: This video deck is provided with a cassette guiding part having a freely opened/closed opening for inserting a tape cassette having a tape wound, an LS main body part for fixing the left and right hubs of the tape cassette guided by the cassette guiding part to a reel, and moving it to a position for driving control, and a tape driving control main body part for pulling out the tape of the tape cassette fixed to the LS main body part, loading the tape in a position where a video recording/reproducing drum is slidably in contact, and guiding it to a position for tape traveling. The tape driving control main body part is provided with a lever mechanism unit, where an opening/ closing mechanism part for locking the opening when the LS main body part is moved to the position for the driving control of the LS main body part, a reel braking mechanism part for braking a reel, and a tape traveling mechanism part for moving a pinch roller to a capstan shaft are integrated.
