本発明はテープカセツトに関し、テープ走行が
円滑に行なわれるようにしたものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape cassette that allows smooth tape running.
従来、テープカセツト内にはテープをカセツト
前面に形成された開口部に沿つて走行させるため
にカセツトハーフ内に植設された軸に嵌入して設

プの走行を悪化させるものである。 Conventionally, a tape cassette is provided with a rotatable tape guide roller fitted into a shaft embedded in the cassette half in order to cause the tape to run along an opening formed in the front surface of the cassette. . However, if the dimensional accuracy of the insertion hole with respect to the shaft is not good, this guide roller may rotate in an inclined state and cause center runout, which will actually worsen the running of the tape.
本発明はこのような従来の欠点を解消したもの
であり、以下その一実施例について図面を用いて
説明する。 The present invention eliminates these conventional drawbacks, and one embodiment thereof will be described below with reference to the drawings.

4 is the tape winding layer part, 15 is the winding layer part 13, 14
The tape in between is guided by the guide pins 2, 3 and tape guides 4, 5 and runs along the openings 8-12. Reference numeral 16 denotes a slippery sheet interposed between the tape winding layer parts 13 and 14 and the half 1, which functions to smooth the rotation of the tape winding layer parts 13 and 14 and to align the wound end surfaces of the tape. It has

成されている。 Here, the tape guides 4 and 5 will be described in detail. The tape guides 4 and 5 are made of fluorocarbon resin or the like and have a coefficient of friction with the tape 15 of 0.15 or less.
On the other hand, as shown in FIGS. 2 and 3, the hole 4a has a diameter smaller at the center than at the upper and lower ends, and is tapered in the vertical direction from the center, and has a circumferential surface. A protruding piece 4b is formed at the lower end.

トツパーは18a,18bで示してある。 On the other hand, the half 1 is provided with stoppers 17a and 17b between which the protrusion 4b is inserted to prevent the tape guide 4 from rotating. to guide you. The tape guide 5 side has a similar structure, with the projecting piece being 5b and the stoppers being 18a and 18b.

走行が行なわれるものである。 By configuring as above, openings 8 to 1
A head, a pinch roller, etc. are inserted from 2, and the tape is run by a capstan and a pinch roller like in a general tape recorder, and recording and playback are performed by the head, but in this case, the tape running through the head section is The height is regulated by a tape guide inserted along with the height.
When the tape 15 is run in an inclined state with respect to the circumferential surface of the tape guides 4 and 5, the tape guides 4 and 5 are placed at the center of the holes 4a and 5a. The tape 15 is tilted using the small diameter part of the part as a fulcrum and follows the inclination of the tape.
This eliminates the partial slack in the tape and allows smooth tape running.

に沿う変位はたとえそのテープ案内体4,5の下
面が平面によつて受けられていてもこのテープ案
内体4,5は非常に軽いためテープ15の走行に

ープ走行面に周面が倣うことになる。 Incidentally, the displacement of the tape guides 4, 5 along the tape running surface is caused by the fact that the tape guides 4, 5 are very light even if the lower surfaces of the tape guides 4, 5 are supported by a flat surface. Due to the deflection tension caused by the running of tape 15, it is lifted upward to some extent and the circumferential surface follows the tape running surface.

る。 Therefore, since the tape guides 4 and 5 are prevented from rotating, the tape guides 4 and 5 are prevented from rotating, and as a result, unlike conventional rotating guide rollers, the tape guides 4 and 5 are not allowed to run unstably due to outer periphery wobbling caused by center runout of the guide rollers with respect to the shaft. This tape guide 4,
Since the tape is automatically tilted to follow the running surface of the tape that is about to be guided by the tape 5, smooth running of the tape is achieved. In addition, by forming the tape guide surfaces of the tape guides 4 and 5 to have a coefficient of friction with the tape of 0.15 or less, the load can be made comparable to that of a rotating guide roller, eliminating an increase in tape running load. can do.

である。 As described above, the present invention includes a shaft implanted in a cassette half, and a tape guide having a hole into which the shaft is inserted, and the central part of the hole of the tape guide is set higher than the upper and lower ends. To stabilize tape running with a simple configuration in which a tape guide is formed to have a small diameter so that it can be tilted to follow the tape running surface, and a rotation preventing means for blocking the rotation of the tape guide is provided. Moreover, the accuracy required for each part can be relaxed, which has a great effect.
