高価となり経済性に問題があった。Most VTRs use the so-called helical scan method, in which the tape is pulled out from a tape cassette containing the tape and wound diagonally around a rotating cylinder containing a magnetic head to transmit and receive signals.
There is. Here, there is a tape drawer for pulling out the tape from the Teig cassette and winding it around the rotating cylinder, and a tape drawer base on which to place and transport the tape drawer.
It is well known that high precision and high rigidity are required in order to obtain good image quality, and for this purpose, aluminum tape is used. It was created by machining cast products such as cast. Furthermore, since the tape is wound diagonally around the rotating cylinder, the slanted tape guide provided to correct the twisting of the tape is made of a stainless steel material with a polished round bar shape and placed on the tape drawer base. They were press-fitted at a predetermined slope. Due to this configuration, even if the required precision and rigidity are satisfied, the price is high and there is a problem in economic efficiency.

生装置のテープ引出体ベースにより達成される。The above purpose is to pull out a magnetic tape from a tape cassette, wrap it diagonally around a rotating cylinder that houses a magnetic head, and send and receive signals? In the magnetic recording and reproducing apparatus, a tape drawer base for drawing out and winding the magnetic chip 1 around the rotary cylinder is formed of synthetic resin, and a tape drawer base for guiding the tape and winding it around the rotary cylinder. A magnetic recording and reproducing device in which an inclined tape guide is fixedly provided to the base of the first drawer body and is integrally molded with the base of the tape puller body using synthetic resin to prevent twisting of the tape for winding the tape at an angle. This is achieved by the tape drawer base.

せ上記支障の発生乞阻止でざる。As described in the explanation of the examples below, an appropriate amount of carbon, minerals, etc. is added to PPS resin (polyphenylene sulfide), which is a type of engineering glass that has seen remarkable technological progress in recent years. It is possible to obtain a predetermined precision by blending, and it is technically possible to manufacture the tape drawer base from synthetic resin. In addition, the inclined tape guide generates minute vibrations when the tape is running due to load loading and fluctuations in the surface friction coefficient, etc. When the tape is running, the vibration becomes a dog and becomes a serious problem when running the tape. Trouble! ' High rigidity is required to achieve this, but by installing reinforcing ribs in areas other than the tape winding range of the inclined tape guide integrally formed on the tape drawer base, the rigidity can be increased. It is necessary to prevent any trouble from occurring.

要である。Hereinafter, a tape drawer-based embodiment of a magnetic recording/reproducing apparatus according to the present invention will be described with reference to FIGS. 1 and 2, and the same parts as those in the prior art will be designated by the same reference numerals and explanations of the structures of the same parts will be omitted. 1st
Figures (a) and (b) are perspective views of the tapes loaded with tape drawers, respectively, and Figures 2 (a) and (Ron are the respective tape drawer bases in Figure 1 with the tape drawers removed). In the figure, the tape drawer base 8.9 is molded by a high-precision resin molding method such as injection molding, using a material in which appropriate amounts of carbon, minerals, fluorine, etc. are mixed with PP5H material. The tape drawer bases 8 and 9 each have an inclined tape guide 10.
．． 11 is integrally molded with resin. In addition, PP8 resin is a -f series of engineering glasses with remarkable technological progress in recent years, and is technically capable of achieving a high degree of heat on tall trees. And the inclined tape guide 10
．． Within the range of 120 windings of 11, the inclined guide 10 has an arc-shaped part 10 east 1, and the inclined tape guide 11 has an arc-shaped part! 1167 and is the running part of tape 2,
The surface finish shape is formed by a mold capable of finishing the tape to a surface roughness considered to be optimal for running the tape, that is, an approximate road surface roughness of 02 to 0.5 μm. In addition, reinforcing rib portions 10a and 11c are formed on the opposite side of the arcuate portions 1oa and ia, that is, outside the wrapping range of the cheese 2, thereby increasing the rigidity. The strength of the PPS resin-molded cheese drawer bases 78, 9 was experimentally determined to have a bending elastic modulus of approximately 1.7 x 10' My/d, and it was confirmed that there was no problem in terms of image quality. ing. As shown in FIG. 3, the flap drawer base 8.9 constructed as described above wraps the tape 2 around the rotating cylinder 4 to achieve a predetermined performance Z.
Can you get lower manufacturing costs compared to traditional equipment? It can be significantly reduced. In addition, tape drawer base 8,9χPPS
Since it is formed by resin molding and precisely formed by resin molding integrally with the inclined tape guide don, no mechanical work is required.

低下し経済性を向上できる。In this way, the tape drawer base of the magnetic recording/reproducing device of this embodiment is formed by molding PPS resin, and the inclined tape guide is also formed by molding resin, so that accuracy, rigidity, etc. are improved. Not satisfied with the product, it was formed from die-casting material and machined as before.
Since there is no ch, the number of work steps can be significantly reduced, manufacturing costs can be lowered, and economic efficiency can be improved.
