Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a frame structure of a device.

(B) Conventional Technology Conventionally, in audio equipment such as a stationary type tape deck and R-DAT, a mechanism substrate in which a tape drive mechanism unit is incorporated and various circuit components related to the tape drive mechanism unit are mounted. After mounting the printed circuit boards and the like to be respectively mounted on a frame, the frame is covered with a top plate or a bottom plate for exterior to form a device body. Specifically, such a frame includes a front frame and a rear frame whose height and width dimensions are substantially equal to the height and width of the device body, and a front frame whose height and width dimensions are substantially equal to the height and depth of the device body. And left and right side frames attached to the rear frame, and a partition frame attached to the front frame and the rear frame, the height and width dimensions of which are substantially the same as the height and depth of the device body.

(C) Problems to be solved by the invention However, in the conventional frame structure, not to mention the case of a new model in which the size of the device body is entirely changed due to a design change, a mechanical form change, or the like, Even in the case of a model in which only the height dimension was changed, it was necessary to make each frame for each model. Therefore, a dedicated frame die is required for each model, and the die cost increases, and a great deal of time is required for the work and management.

(D) Means for Solving the Problems The present invention has been made in view of the above-mentioned problems, and is an apparatus configured by attaching a top plate or a bottom plate for exterior to a frame, The front frame and the rear frame that define the width, and the height dimension is set to be smaller than the height of the device body to define the depth of the device body and downward (or upward) direction to support the bottom plate (or top plate) The left and right side frames whose front and rear ends are attached to the front frame and the rear frame at positions displaced from each other, and the height dimension of the left and right side frames is set to be smaller than the height of the device body, and the left and right side frames are partitioned and the top plate (Or a bottom plate) is configured to include a partitioning frame whose front and rear ends are attached to the front frame and the rear frame at positions displaced in the opposite direction to the side frame so as to support the bottom frame. It

(E) Operation In the frame structure of the present invention described above, the left and right side frames and the partition frame, whose height dimension is set smaller than the height of the device body, are staggered vertically to obtain a predetermined device body height. Therefore, it is possible to use a common side frame and partition frame between models having different heights and widths. Here, the width of the device body can be easily changed by changing the facing distance between the left and right side frames. Furthermore, if the left and right side frames and the partition frame are made to have the same size and the same shape so that the necessary cut and raised pieces and screw holes etc. are preliminarily formed together, the left and right side frames can be formed with one frame mold. And a partition frame can be made,
Significant cost reduction and work reduction can be achieved.

(F) Embodiment An embodiment of the present invention will be described below with reference to the drawings.

That is, the frame structure of the present invention is as shown in FIG. 1 and FIG. 2, and (1) and (2) are metallic front faces whose height and width dimensions are substantially equal to the height and width of the device body. With the frame and the rear frame, the front frame (1) to which the resin front panel for cosmetics is attached, has the first insertion hole (1a) corresponding to the cassette insertion opening of the front panel and the second insertion hole corresponding to the display section. Holes (1b) are formed respectively. (3) (4) is a cross-section whose upper and lower front and rear ends are bent so that its height dimension is smaller than the height of the equipment body by a predetermined amount and its width dimension is approximately equal to the depth of the equipment body. The left and right metal side frames are shaped like a letter.The left and right side frames (3) and (4) have screw holes (3a) at their front and rear ends at a position displaced downward so as to support a bottom plate for exterior. ) (1c) (3b) (2a) (4a) (1e) (4b) (2b)
It is screwed to the front frame (1) and the rear frame (2) via the. (5) is a metallic partition frame having the same size and shape as the left and right side frames (3) and (4) .The partition frame (5) is located at a position displaced upward so as to support the exterior top plate described later. At the front and rear ends of the screw holes (5a) (1d) (5
b) It is screwed to the front frame (1) and the rear frame (2) via (2c). In addition, (6) is a fixed board to which a mechanism board incorporating the tape drive mechanism is mounted, and this mounting board (6) is a left side frame (3) and a partition frame (5).
It is screwed through the screw holes (3c) and (5c). (7) is a main printed circuit board on which various circuit components are arranged. One end side of the main printed circuit board (7) is the right side frame (4).
It is sandwiched between the cut and raised pieces (4c) and (4d), and the other end is screwed to the partition frame (5) through the screw holes (5d) and further fixed substrate
It is screwed to (6). And (8) is a sub-printed circuit board on which various circuit parts are arranged.
One end of (8) is sandwiched by the cut-and-raised pieces (5e) (5f) of the partition frame (5) and the other end is screwed into the screw hole (4) on the right side frame (4).
It is screwed on via e).

Therefore, the bottom plate (9) is attached to the frame having the above structure from the lower surface side, and the top plate also serving as the side plate from the upper surface side.
When the (10) is attached, the device body having the dimensions shown in Fig. 2 is constructed. Where W ₁ is the left and right side frames
(3) (4) distance, h is the height of the left and right side frames (3) (4) and the partition frame (5), α ₁ is the left and right side frames (3) (4) and the partition frame (5) It is a vertical shift. In this case, the front frame (1) is covered with the cosmetic front panel, the rear frame (2) is used as it is, and the bottom plate (9) is the front and rear frames (1) (2) and the left and right side frames. (3) (4)
And the left and right side frames (3) and (4) are screwed to the lower ends of the left and right side frames (3) and (4) through screw holes (3d) and (4f). And the top plate (1
(0) is supported by the front and rear frames (1) (2) and the partition frame (5), and the left and right side frames (3) (4) have screw holes (3e) (4g).
It is screwed through.

Next, Fig. 3 shows the left and right side frames (3) (4) and the partition frame.
The vertical displacement of (5) is set to α ₂ and the left and right side frames (3)
(4) The distance between them is set to W ₂ , and the same side frame (3) (4) and partition frame are used for models with different height and width of the device body.
An example constructed using (5) is shown, in which case only the front and rear frames (1) and (2) are newly made.

In this embodiment, the left and right side frames and the partition frame are made to have the same size and the same shape by using the same mold so that the necessary cut and raised pieces, screw holes, etc. are formed in advance. However, for example, the three members may be created by using individual molds, or only the common portion may be created by the same mold, and each necessary one may be created by individual molds. .

(G) Effect of the Invention As described above, according to the frame structure of the present invention, the left and right side frames and the partition frame whose height dimension is set smaller than the height of the main body are staggered in the vertical direction and the predetermined equipment is shifted. Since the height of the main body is obtained, it is possible to use a common side frame and partition frame between models having different heights and widths.
It is possible to significantly reduce the management process.
