An embodiment of the present invention will be described below with reference to the drawings. Figure 1 is a plan view showing the state in which the first base body and the second base body are attached to the resin molding frame, Figure 2 is a plan view showing the state in which only the second base body is attached, Figure 3, Figure 4. The figures are a plan view and a side view of the resin molding frame. A resin molded frame 6 in which the frame structure of the set is molded from resin includes positioning pins 1 for the first base 4.
and holes 6b1 for attaching the first base body 4 to the resin molding frame 6 with the fastening screws 2; the second base body 5 is also connected to the resin molding frame 6;
A hole 6a for mounting is provided (FIGS. 1 and 3). Further, surfaces 6d and 6c for holding the first base body 4 and the second base body 5 are provided parallel to each other on different levels (FIG. 3). As shown in FIG. 1, a push button 7, a feed reel stand 8, a take-up reel stand 9, a rewind roller 10, a fast-forward roller 11, and other drive mechanisms are mounted on the first base body 4, as shown in FIG. On the second base 5, as shown in FIG. 1, a tape running path such as a pinch roller 12, a capstan 16, a motor 1, an audio/control magnetic head 13, a rotating drum 15, etc. are mounted. The first base body 4 and the second base body 5 are assembled in advance as respective blocks, and each is individually checked for adjustment using a jig or the like.

で調整チェックをを行うことができる。When assembling, first, the second base body 5 is placed on the surface 6c of the resin molding frame 6, as shown in FIG. Next, the first base 4
is placed on the surface 6d, resulting in the state shown in FIG. At that time,
As shown in FIG. 6, the holes in the first base 4 fit into the positioning pins 1 provided on the resin molding frame 6, so that the position of the first base 4 with respect to the resin molding frame 6 is accurate. It can be decided. Further, as shown in FIG. 7, the hole of the first base body 4 fits into the mounting member 5a provided on the second base body 5, so that the first base body 4 and the second base body 5 are connected in a plane. The positional relationship is determined. The height of the mounting member 5a is different from that of the resin molding frame 6. Parallel surfaces 6c, 6
Similar to the step d, the parallelism between the first base 4 and the second base 5 is also maintained as shown in FIG. First, tighten the two 2" fastening screws (Figures 1 and 5) to connect the first base body 4 and the second base body 5, and then insert the first base body 4 into the hole 6b of the resin molding frame 6. Tighten the screws 2 at the parts shown in FIG. 1.Finally, tighten the screws into the holes 6a to obtain the state shown in FIG. It is designed so that it can be assembled only from the direction perpendicular to 6d.According to the present invention, by dividing the mechanical part into two blocks, each can be assembled on a sub-line, and furthermore, adjustments can be made with each block. Checks can be made.
従つて部品組付、調整チェックの際の基体の取り置きが

も正確に構成することができる。Therefore, it becomes very easy to set aside the base body when assembling parts and checking adjustment, and these operations can be easily performed by hand, which has a great effect on improving productivity. Also, if the frame body to which the base bodies of these two blocks are attached is provided with a surface for holding the two base bodies parallel to the main plane of the base body, and this is integrally molded with resin, the planes of the two base bodies can also be configured accurately. I can do it.
この様にして、樹脂によつて一体成形された枠体に別の

ンを比較的短かく構成することができるので生産設備の
大型化を防ぐこともできる。In this way, the assembly line for the main body can be made relatively short by assembling two blocks that have been preassembled on a separate assembly line and have undergone adjustment checks to a frame integrally molded from resin. This also prevents the production equipment from becoming larger.
