DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the fixed head device of the present invention will be described in detail below with reference to FIG.

In FIG. 1, parts corresponding to those in FIG. 3 are designated by the same reference numerals, and detailed description thereof will be omitted.

In FIG. 1, reference numeral 200 denotes a rotary type guide post, which is formed by sequentially inserting a spool 60 and an upper flange 20 on a shaft set up on a base 51. The spool 21 is positioned by the upper flange 20. The length of the spool 60 in the width direction of the magnetic tape 24 is made longer than that when the flanges are attached vertically.

On the other hand, the base 51 has a recording / reproducing head 50.
Is stuck. The recording / reproducing head 50 is formed by integrally forming a flange 26 on the lower portion of the recording / reproducing head 50, or by mounting the head 25 on a head mount 50b to which the flange 26 is attached without a gap.

In this structure, when a capstan and a pinch roller (not shown) are driven, the magnetic tape 24 runs and its upper side (tape edge) is regulated by the upper flange 20 of the rotary guide post 200. Guided by the spool 60. And magnetic tape 24

However, the lower side of the magnetic tape 24 cannot be regulated by the rotary guide post 200. However, the position of the edge portion of the magnetic tape 24 can be regulated by the head mount 50b and the flange 26 of the recording / reproducing head 50 formed or attached to the lower part of the recording / reproducing head 50, and there is a gap between the head mount 50b and the flange 26. In addition, since the recording / reproducing head 50 does not rotate, the edge portion of the magnetic tape 24 does not enter the gap as in the case where the lower flange is attached by the rotary guide post 200, and therefore, Good tension can be achieved without increasing the tension of the magnetic tape 24.

As described above, in this embodiment, only the upper flange 20 is used as the flange of the rotary guide post 200 before the recording / reproducing head 50, and the upper side of the magnetic tape 24 is regulated by this rotary guide post 200. Since the lower side of the magnetic tape 24 is regulated by the flange 26 of the recording / reproducing head 50, the magnetic tape 2 is guided.
It is possible to prevent an increase in the tape tension of the magnetic tape 24 and to realize good tape running without damaging the magnetic tape 4.

The second pattern is the case where the rotary guide post 200 shown in FIG. 1 has no upper and lower flanges and the flange 26 is formed or attached to the lower portion of the recording / reproducing head 50.

In this case, the rotation guide post 200 cannot regulate the vertical direction of the magnetic tape 24, but the flange 2 formed or attached to the lower portion of the recording / reproducing head 50.
6, the lower side of the magnetic tape 24 can be regulated. In this case as well, the magnetic tape 24 can be controlled in the same manner as in the case described with reference to FIG.
The magnetic tape 24 can be prevented from being damaged, the tape tension of the magnetic tape 24 can be prevented from increasing, and good tape running can be realized.

The third pattern is the case where the flange is attached to the lower side of the rotary guide post 200 shown in FIG. 1 and the flange 26 is formed or attached to the upper part of the recording / reproducing head 50.

In this case, the rotation guide post 200 cannot regulate the upward direction of the magnetic tape 24, but the rotation guide post 200 regulates the downward direction of the magnetic tape 24 for recording / recording.
The upper side of the magnetic tape 24 can be regulated by the flange 26 formed on or attached to the reproducing head 50.
Also in this case, as in the case described with reference to FIG. 1, the magnetic tape 24 is not damaged, and the tape tension of the magnetic tape 24 is prevented from increasing, so that good tape running can be realized.

The fourth pattern is the rotary guide post 200 shown in FIG. 1, in which the flange is attached to the upper side as in FIG. 1, and the flange 2 is attached to the lower part of the recording / reproducing head 50.
This is the case when 6 is formed or attached.

In this case, the rotation guide post 200 cannot regulate the downward direction of the magnetic tape 24, but the rotation guide post 200 regulates the upward direction of the magnetic tape 24 for recording / recording.
The lower side of the magnetic tape 24 can be regulated by a flange 26 formed or attached to the lower part of the reproducing head 50,
Also in this case, as in the case described with reference to FIG. 1, the magnetic tape 24 is not damaged, and the tape tension of the magnetic tape 24 is prevented from increasing, so that good tape running can be realized.

The fifth pattern is the rotary guide post 200 shown in FIG.
This is the case where the flange 26 is formed or attached to the upper part of the recording / reproducing head 50.

In this case, the rotation guide post 200 can regulate the magnetic tape 24 in the vertical direction, and the flange 26 formed or attached to the upper portion of the recording / reproducing head 50 can regulate the upper portion of the magnetic tape 24 and the magnetic tape. It is possible to prevent the magnetic tape 24 from entering the gap between the flange and the spool, prevent the magnetic tape from being damaged, and prevent the tape tension of the magnetic tape 24 from increasing, thereby realizing good tape running.

The sixth pattern is the rotary guide post 200 shown in FIG.
This is the case where the flange 26 is formed or attached to the lower portion of the recording / reproducing head 50.

In this case, the rotation guide post 200 can regulate the magnetic tape 24 in the vertical direction, and the flange 26 formed or attached to the lower portion of the recording / reproducing head 50 can regulate the magnetic tape 24 on the lower side and the magnetic tape 24. It is possible to prevent the tape 24 from entering the gap between the flange and the spool, prevent the magnetic tape from being damaged, and prevent the tape tension of the magnetic tape 24 from increasing, so that good tape running can be realized.

In this example, the height of each linear track audio from the lower edge of the magnetic tape 24 can be determined by the mechanical accuracy of the fixed head itself. As shown in FIG. 5, linear track audio data as indicated by 33, 34, and 35 exist on the magnetic tape 24 depending on the format. Normal,
It is not easy to adjust the height of each linear track audio data 33, 34 and 35 when adjusting the tape running. This is because the height of each linear track audio data 33, 34, 35 cannot be visually confirmed from the tape lower edge in the state of the fixed head after the assembly of the conventional running system.

However, when the flange 26 as shown in FIG. 1 is formed or attached to the recording / reproducing head 50, after the traveling system is assembled, the linear track audio data 33, 34 from the tape lower edge, The height of 35 can be visually confirmed. After that, if you can make fine adjustments to the fixed head, linear track
The height of the audio data 33, 34, 35 can be easily adjusted.

The above embodiment is an example of the present invention.
It goes without saying that various other configurations can be adopted without departing from the scope of the present invention.
