Abstract: There is provided a recording and reproducing apparatus to which two tape cassettes of different sizes having supply reels and take-up reels to and around which respective ends of a magnetic tape are fixed and wound are loadable, the supply reels and the take-up reels being spaced apart by different spacings and in which reel turntables (18,18') that are in engagement with the tape reels are translated between two positions. In this recording and reproducing apparatus, an indirect driving in which the reel turntables are rotated by an existing motor, such as a capstan motor (29) or the like without using a reel motor exclusively-designed for rotating a reel turntable is made possible. Thus, the recording and reproducing apparatus can be miniaturized, made light in weight and inexpensive. Reel turntables (18, 18') can rotate about supporting points (16a, 16a') which are supported to the mechanical chassis (17) such that they can be translated between two positions. A drive gear (39) supported to a swing arm (38) and which is driven by a capstan motor (29) is selectively meshed with one of driven gears (19, 19') provided on the two reel turntables (18, 18'), and the reel turntable is rotated by the drive gear.

Abstract: A tape-loading mechanism of a magnetic recording and reproducing apparatus according to the present invention has a tape travel system in which a magnetic tape drawn out of a supply-side tape reel is helically wound around a drum along a lead thereof by tilted guides respectively provided on inlet and outlet sides of the drum and tape guides respectively provided on inlet and outlet sides thereof, passed via a capstan and wound around a takeup side tape reel. A vertical position of the lead of the drum is set equal to that of a lower edge of the tape in a state immediately before the magnetic tape is loaded onto the drum. The magnetic tape is twisted in the middle of the tape travel system in order to cancel difference in tension between upper and lower edges of the magnetic tape when the magnetic tape is loaded onto the drum.

Abstract: A recording and reproducing apparatus can translate a detecting device for detecting information, such as the kind and content of tape cassette and a reel lock mechanism releasing device to proper positions corresponding to tape cassettes of different sizes. A tape cassette information detecting means (71) and reel lock releasing means (72a, 72b) can be translated to positions at which large and small tape cassettes are in use through a swing drive member (54), a translating lever (73), a driving link (74), a detection mechanism holding member (75) and a reel lock releasing plate (77) in unison with a movement of reel mounts (44, 45).

Abstract: The tape loading mechanism has a device to regulate the vertical position of the inclined guide (12,15) on the tape winding drum (13). This is arranged to correspond to a lower edge of the tape, immediately preceding the loading of the tape onto the drum. The tape is placed under torsion by a mechanism in the middle of the tape handler, so that the difference in tension between the top and the bottom edges of the tape is cancelled when the tape is loaded onto the winding drum. The torsion is applied by the tape guide (16) placed at the delivery side of the drum, and the pinch roller and the capstan.
