【Example】

 Embodiments of the present invention will be described below with reference to the drawings. The unit according to the embodiment of the present invention has an electric circuit board having a specific function in the cassette 1. Each unit is composed of a cassette 1 which is functionally independent and sealed one by one. At the lower edge of the cassette 1, there is a convex edge 11 having a periphery, and in order to be able to fit with another cassette 1, a single convex portion 12 is provided on the convex edge 11 as shown in FIG. .. Correspondingly, there is a concave edge 13 corresponding to the convex edge 11 on the upper peripheral edge of the upper cassette 1, and a linear groove 14 is provided on the concave edge 13, and the convex portion 12 is fitted into the concave groove 14. Then, the upper cassette 1 and the lower cassette 1, that is, the upper unit and the lower unit are combined and fixed.

There is a female seat 16 of one connecting block on one of the suitable positions of the cassette 1, for example, the upper right wall 15 of the cassette 1, and the female seat 16 has several contact legs 16a and 16b. , Used to connect the circuits inside the cassette 1. A corresponding male seat 18 is also provided on the corresponding right end portion of the lower wall 17 of the cassette 1. The male seat 18 is inserted into the female seat 16 by inserting the male seat 18 into the female seat 16 when the upper cassette 1 and the lower cassette 1 are fitted to each other. , Form a passage. Therefore, in the cassette 1, the male seat 18, the female seat 16 and the electric circuit board are connected to each other with some integrated circuits (using an array line or a PC board). For example, 120 leg contact circuits are provided between the male seat 18 and the female seat 16, the 1st to 15th legs supply power to each unit at the power supply layer, and the 16th to 25th legs are the instep unit layer and the main body layer. For the special use of electric signals, the 26th to 35th legs are dedicated to connecting the electric signals of the second unit layer and the main body layer, and the signal connection legs not used for each unit layer do not communicate with the PC board of the unit layer. , The male and female seats are directly connected by the arrangement line 19 so that a distribution state is exhibited. Since each unit layer communicates with the power supply layer, that is, the main body layer, the unit layer has an independent function. For example, when the IO layer is in communication with the power supply layer, that is, the main body layer, the IO layer can be connected to peripheral equipment such as a printer by an external contact plug. This circumscribing plug can be covered with a cap when not in use to keep the appearance simple. Further, the positions of the male seat 18 and the female seat 16 can be set to different positions among the plurality of cassettes 1, and the legs of the connecting portion can be appropriately selected and used.

When the embodiment of the present invention is applied to a personal computer, the main body layer, the hard disk layer, the soft disk layer, the power supply layer, the monitor layer, the IO layer, etc. are designed as individual independent cassette type units. When applied to a stereo, the stereo can be made into a cassette, and the power supply layer, radio layer, recorder layer, etc. can be housed in separate cassettes and stacked. These can be freely selected and assembled according to the needs of the user. It should be noted that the drawings are merely examples of preferred embodiments and do not limit the scope of the disclosed invention. Therefore, even if there is a change in the local portion of the above-mentioned embodiment, for example, a change or modification of the cassette fitting method, a difference in the positions of the male seat and the female seat, etc., based on the concrete idea of the present invention, Anything that can be easily inferred by a person skilled in the art does not depart from the scope of the present invention.
