Magnetic recording and playback apparatus

Claim 1

A magnetic recording and playback apparatus, in which a magnetic tape is extracted by means of a tape extracting pin from a tape cassette and wound around a cylinder incorporating therein rotary heads over a predetermined angle so that said rotary heads record and play back signals on said magnetic tape, said apparatus comprising a base plate for holding reel bases vertically and for mounting thereon said tape cassette in parallel therewith, and first, second and third inclined guide planes of different directions and angles of inclination with respect to said base plate, said cylinder incorporating therein said rotary heads arranged perpendicularly on said first inclined plane, said apparatus further comprising a first guide post and an eraser head arranged perpendicularly with respect to said third inclined plane, a second guide post, a sound/control head and a capstan arranged perpendicularly with respect to said second inclined plane, means for bringing and keeping a pinch roller into a posture perpendicular to said second inclined plane during travelling of a tape, and first and second inclined posts arranged in the vicinity of intersecting lines of said base plate and said third inclined plane, and of said base plate and said second inclined plane, respectively, said first inclined post being adapted to stretch a magnetic tape extracted by said tape extracting pin from said tape cassette, along said third inclined plane before said magnetic tape is wound around said cylinder by way of said first guide post and said eraser head, and said second inclined post being adapted to redirect said magnetic tape which comes from said cylinder and travels by way of said second guide post, said sound/control head and said capstan arranged on said second inclined plane, so that the magnetic tape stretches in parallel with said base plate.
