A recording and reproducing apparatus includes a guide post for pulling out a tape-shaped recording medium from a cassette and wrapping the tape-shaped recording medium around a rotary drum, a guide base which supports the guide post, the guide base being movable between a first position in which the cassette can be loaded and a second position in which a recording or reproducing action can be performed with the tape-shaped recording medium wrapped around the rotary drum at a predetermined angle, and an elastic member for, after the guide base moves from the first position to the second position, urging the guide base toward the second position to position the guide base at the second position. The elastic member is disposed on an upper surface of the guide base.

1. Field of the Invention
The present invention relates to a recording and reproducing apparatus, and more particularly to a recording and reproducing apparatus arranged to perform a recording or reproducing action by pulling out a tape-shaped recording medium from a cassette and wrapping the tape-shaped recording medium around a rotary drum.
2. Description of Related Art
FIG. 1 is a plan view showing a tape loading apparatus, serving as a recording and reproducing apparatus according to an embodiment of the invention, in a loading standby state.
FIG. 2 is a plan view showing the tape loading apparatus, according to the embodiment, in a loading completion state.
FIG. 3 is an exploded perspective view showing a supply-side guide post base unit shown in FIG. 1.
Hereinafter, a preferred embodiment of the invention will be described in detail with reference to the drawings.
FIG. 1 is a plan view showing a tape loading apparatus, serving as a recording and reproducing apparatus according to the embodiment of the invention, in a loading standby state. FIG. 2 is a plan view showing the tape loading apparatus, according to the embodiment, in a loading completion state. First, the basic structural arrangement and the operation of the tape loading apparatus according to the embodiment are described below with reference to FIGS. 1 and 2.
Referring to FIGS. 1 and 2, a rotary drum 1 has magnetic heads (not shown) mounted thereon. A drum base 2 is arranged to support the rotary drum 1. A guide rail 3 has cam grooves 16 formed therein. A loading motor 4 is arranged to serve as a drive source of a tape loading mechanism. A pinch roller 5a is arranged to be pressed against a capstan 21 across a tape, so as to transport the tape. A pinch roller arm 5 is arranged to swing the pinch roller 5a. A supply-side guide post base unit 6 is provided with a supply-side guide post 61 (shown in FIG. 3) arranged to determine a slanting angle at which the tape is wrapped around the rotary drum 1 on the side of a supply reel (hereinafter referred to as a supply side). A take-up-side guide post base unit 7 is provided with a take-up-side guide post arranged to determine a slanting angle at which the tape is wrapped around the rotary drum 1 on the side of a take-up reel (hereinafter referred to as a take-up side). The tape loading apparatus further includes a main chassis 8, a supply reel mount 9 and a take-up reel mount 10. A tension post 11a is arranged to pull the tape out from a tape cassette and to impart a suitable amount of tension to the tape. A tension arm 11 is arranged to swing the tension post 11a. A take-upside pull-out post 12a is arranged to pull the tape out from the cassette on the take-up side. An arm 12 is arranged to swing the take-up-side pull-out post 12a. A slide chassis 13 is arranged to be slidable. The cam grooves 16 are formed in the guide rail 3 to guide the guide post base units 6 and 7. Reference numeral 17 denotes the tape cassette, and reference numeral 18 denotes the tape. A cassette opening part 19 is formed in the front surface of the tape cassette 17. The tape loading apparatus further includes a main slanting post 20 and a capstan 21, which is disposed on the main chassis 8 to be rotatable for transporting the tape 18.
