かが認識できる。Configuration of Conventional Example and its Problems First, an example of application of a rotation adjustment jig to a post device in a magnetic recording/reproducing device (hereinafter referred to as a VTR) will be described. In FIG. 1, a magnetic tape 1 includes a pair of rotating roll posts 2 that regulate the vertical direction of the magnetic tape 1 by regulating stages 2A and 2B, and a pair of inclined posts 3 disposed between these rotating roller posts 2. The guide drum 4 is regulated and guided by the guide drum 4, and runs along the lead 4A, which is the regulating stage of the guide drum 4, which has a rotary head therein, thereby recording and reproducing video signals. Therefore, in order to obtain high image quality and compatibility with other VTRs, the magnetic tape 1 must accurately run in the correct position. In particular, rotating roller post 2
The positional accuracy of the tilted post 3 relative to the position is important.
If the tilted post 3 is out of position, the magnetic tape 1 will be pressed against one side of the regulating stages 2A and 2B of the rotating roller post 2, and as a result, a large internal stress will be generated on the end surface of the magnetic tape 1, causing the magnetic tape to Tape 1 will be damaged. Further, the magnetic tape 1 is lifted off the lead 4A, and the head inside the guide drum 4 cannot accurately trace the magnetic tape 1.
If the position of the inclined post 3 is out of order in this way,
Since the magnetic tape 1 may be damaged or accurate tracing may not be possible, noise may appear on the screen and the image quality may be significantly degraded. From the foregoing, it can be recognized how important the position adjustment of the tilt post 3 is.
しかるに、従来のVTRのポスト装置に用いる

う問題があつた。以下に、第2図、第3図に基づ
いて従来例を説明する。 However, with the jigs used in conventional VTR post devices, there has been a problem in that it is difficult to perform highly accurate position adjustment. A conventional example will be explained below based on FIGS. 2 and 3.

雌螺子部13を設けている。 In FIGS. 2 and 3, the adjustment table 5 that supports the inclined post 3 at a predetermined angle of inclination is attached to the mounting table 6.
The roller post 2 is rotatably fitted loosely into the regulating step 2B of the rotating roller post 2 which is to be erected on the roller post 2. Further, the rotating roller post 2 rotatably supports the rotating roller 7 between the regulating step portions 2A and 2B. The adjustment table 5 and the mounting table 6 are provided with a cutout recess 9 and a recess 10 that engage with the flat jig 8, respectively. Also, adjustment table 5
is provided with a long hole 12 through which the fixing screw 11 is inserted, and the mounting base 6 is further provided with a female screw portion 13 that pairs with the fixing screw 11.

ものである。 In the conventional configuration described above, the jig 8 is connected to the cutout recess 9
and the recessed part 10, respectively, and the recessed part 10
By moving the jig 8 within the range of play between the thickness of the jig 8 and the width of the recess 10, the regulating step 2B of the rotating roller post 2 is guided between the adjustment table 5 and the mounting table 6. It can be rotated as After rotating to a predetermined position, the adjustment table 5 is fixed to the mounting table 6 by tightening the fixing screw 11.

Furthermore, due to the structure of the jig, it is necessary to make the mounting base 6 larger than the adjustment base 5 and provide a recess 10 in that space, which also poses a problem in terms of miniaturization of the equipment.

上に配してある。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 4 and 5. An adjustment stand (second support stand) 5 that supports the inclined post 3 at a predetermined angle of inclination is rotated around the regulating step 2B of the rotating roller post 2 that is installed on the mounting stand (first support stand) 6. It is fitted loosely so that it can move freely. The rotating roller post 2 has regulating step portions 2A and 2B.
A rotary roller 7 is rotatably supported between them. The adjustment table 5 has a cutout recess (engaged part) 9 that engages with a jig, and is further provided with a long hole 12 through which a fixing screw 11 is inserted. Further, the mounting base 6 is provided with a female screw portion 13 that pairs with the fixing screw 11. The rotation adjustment jig 14 includes a handle portion 15 for an operator to support and rotate the jig, a columnar portion 16 connected from the handle portion 15, and a columnar portion 16.
a rotation guide portion 17 that is located at the tip of the fixing screw 11 and rotatably loosely fits into the fixing screw 11;
The L-shaped part (engaging part) 18 is connected to the notch recess 9 and engages with the notched recess 9. Furthermore, a driver 19 is provided inside the handle part 15 to the columnar part 16. A through-hole portion 20 is formed through which the screwdriver 19 is inserted and which guides the rotation of the driver 19. Note that the rotation guide portion 17 and the through hole portion 20 are arranged coaxially.

業が行なえるという利点もある。Effects of the Invention As described above, if the rotation adjustment jig according to the present invention is used, the looseness of the guide portion of the jig can be eliminated because the fixing screw is used to guide the rotation of the jig, and the jig structure can also be improved. Smooth and highly accurate rotational adjustment can be performed very easily and without increasing the number of parts for guiding the jig on the side of the member to be adjusted. Moreover, there is no need for the first support base (mounting base) to have a part that engages with the jig, and the first support base can be made smaller than before, making it possible to downsize the device. In addition, since the rotation guide part that fits the fixing screw is provided coaxially with the through hole part, when adjusting the rotation or fixing the second support base, the driver and jig can be set alternately each time. This has the tremendous effect of allowing work to proceed almost simultaneously without having to make any repairs. Furthermore, the through hole also serves as a rotational guide for the screwdriver, which has the advantage of allowing quick screw tightening work.
