チャベースを得ることができる。In FIG. 1, a cylinder 1 which records on a magnetic tape or reproduces data from a magnetic tape by scanning a magnetic tape (not shown) is screwed to a cylinder base 12, and then this cylinder base 12 is attached to a sub chassis 1.
Fix it in the center of 4. The sub-chassis 4 has a circular hole 18 in the center through which the bearing part 16 of the cylinder 0 passes, and a pair of substantially arch-shaped band-shaped holes 20 and 21 are formed on the outer periphery of the circular hole 18. The guide roller 22 that moves the magnetic tape can be guided. Further, the sub-chassis 14 has a pair of holes 20,
A guide roller catcher 24 (hereinafter referred to as catcher) is fixed to one end of the catcher base 21, and the guide roller 22 is stopped at a predetermined position so that the relative position between the cylinder 10 and the magnetic tape is appropriate. can do. The sub-chassis 14 to which the cylinder 10 and the cylinder base 12 are fixed includes other various small parts 26, 2.
After being fixed to the main chassis 32 together with 8 and 30,
By attaching the main chassis 32 to the frame 34, it is assembled to the frame. When the cylinder base 12 and the catcher base are processed as a single item in this way, it is possible to obtain the cylinder base 12 and the catcher base with high precision.

The number of parts also increases, leading to an increase in cost. In addition, in order to accurately load the magnetic tape into the cylinder 10', not only the processing accuracy of the cylinder 10, the cylinder base 12, the catcher 24, and the catcher base itself, but also the assembly accuracy of determining their relative positions is required. It has the disadvantage that the assembly process and the adjustment of the finished product take a lot of time. Fig. 2 is a plan view of a sub-chassis in which a cylinder base and a catch base are integrally formed in the sub-chassis in order to eliminate the above-mentioned drawbacks, and Fig. 3 is a cross-sectional view taken along line mm in Fig. 2. It is.

。These bosses 36, 38, and 40 are mounting parts for the cylinder 10, and in order to fix the cylinder 10 at a certain angle as shown in FIG.
It is sloped so that it becomes lower from the side toward the hole 21 side, and each upper end is on the same plane. In addition, sub chassis 1
4 has a pair of bosses 42 on the outside of the holes 20 and 21, respectively.
, 44 are provided in a protruding manner so that the catcher 24 (not shown in FIG. 2) can be mounted and fixed thereon. In such a sub-chassis 14, since the cylinder 10 and catcher 24 can be directly attached to predetermined positions on the sub-chassis 14, the relative positions of the cylinder 10 and catcher 24 are automatically determined, making assembly easy and achieving high assembly accuracy. This has the advantage that the number of parts can be reduced. However, since the sub-chassis 14 has a complicated shape, processing methods are limited. Therefore, the bosses 36 and 38, which are the cylinder mounting parts that require the most precision,
, 40 and the bosses 42, 44, which are the catch mounting portions, have drawbacks such as there is a limit to the improvement in precision, and they cannot be manufactured at low cost. The present invention has been made in order to eliminate the drawbacks of the prior art, and an object of the present invention is to provide a cylinder base for a video tape recorder that is integrated with a catcher base that can be processed by various processing methods.

加工方法により加工することができる。That is, as shown in FIG. 4, the catcher mounting part 66 having a substantially plate shape is formed in the tangential direction of the cylinder mounting part 52 on one side of the cylinder mounting part 52 in the radial direction orthogonal to the oblique direction, and is formed in the tangential direction of the cylinder mounting part 52. An inner wall portion 68 of the hole 54 forms a part of the hole 54 . The catcher mounting section 66 includes pedestals 70, 72, and 74 each mounting a pair of catchers on both ends of the inner wall section 68.
, 76 are provided in a substantially straight line. These pedestals 70, 72, 74, and 76 differ from the cylinder mounting portion 52 in that their upper end surfaces are on the same horizontal plane. In addition, the catcher mounting portion 66 has a height direction length (G in FIG. 5) of the pedestal that is twice as large as the diameter of the pedestal (H in FIG. 4), for example, from 1.3 tones. It functions as a reinforcing rib against deformation in the horizontal direction. Further, the catcher mounting portion 66 has a wall thickness 1 greater than the wall thickness E of the cylinder mounting portion 52, reinforcing the cylinder mounting portion 52 and reinforcing the catcher mounting portion 66 itself. In addition, the pedestal 56 of the cylinder mounting part 52 and the pedestal 7 of the catcher mounting part 66
2 is connected to the cylinder mounting portion 52 by a rib 77.
and the catcher mounting portion 66 have a mutually reinforcing relationship. The cylinder base 50 is fixed to the main chassis or sub chassis with bolts or the like through attachment holes 78 provided at both ends of the catcher mounting section 66 and outside the pedestal 58 of the cylinder mounting section 52. As described above, in the cylinder base, the substantially cylindrical cylinder mounting portion 52 and the substantially plate-shaped catcher mounting portion 66 are integrally formed, so that the cylinder mounting portion 52 and the catcher mounting portion 66 mutually reinforce each other. Therefore, the accuracy of the relative position between the cylinder mounting part 52 and the catcher mounting part 66, that is, the relative position between the cylinder and the catcher, can be improved, and the position of the magnetic tape with respect to the cylinder can be made more accurate. Further, in the cylinder base 50 of this embodiment, since the cylinder mounting portion 52 has a stable substantially cylindrical shape, deformation due to external force, residual stress, etc. after assembly is extremely small. Furthermore, the cylinder base 50 has a simple shape, consisting of a substantially cylindrical cylinder mounting portion 52 and a substantially plate-like catcher mounting portion 66, which not only allows for saving of materials and weight reduction, but also allows for a video tape recorder. It can be formed by various processing methods depending on the model. In other words, if you need something lighter and cheaper, synthetic resin (
(Synthetic resin alone or with other particle or fibrous fillers)
If you need a material that can be molded with high mechanical strength and is stable against external forces, you may need a lightweight, high-strength material that has properties intermediate between the above two. In this case, it can be formed by aluminum die-casting. As explained above, according to the present invention, by integrally forming the substantially cylindrical cylinder mounting portion and the substantially linear catcher mounting portion, the cylinder base integrated with the catcher base can be formed by various processing methods. Can be processed.
