As an example of this PC, a main body unit having a keyboard on its upper surface and a display unit having a display screen that can be opened and closed with respect to the main body unit are opened. Background Art So-called notebook personal computers (hereinafter, abbreviated as notebook PCs) in which a display screen is folded so as to be superimposed on a keyboard are widely known.

Recently, a so-called tablet-type personal computer (type) having a display screen on the upper surface thereof, which is formed in a single plate shape and inputs instructions by bringing a pen into close proximity or contact with the display screen and recognizing the proximity or function position thereof. Hereinafter abbreviated as tablet PC) has appeared.

In addition, recently, the main unit and the display unit are connected via a two-axis connecting portion for supporting the opening and closing or pivoting, the display unit can be used as a notebook PC, and the display unit is raised above the main unit. Electronic devices which can be used as tablet PCs stacked in a state have appeared.

Miniaturization is also required for general electronic devices such as PCs. However, in the case of notebook PCs and tablet PCs as described above, since miniaturization is required, miniaturization and thinning are strongly demanded. In recent years, notebook PCs have been equipped with a high level of functionality that is inferior to that of a stationary so-called desktop computer. Therefore, it is required to realize miniaturization and thinning, and to maintain high operability so as not to lag behind such a high functionalization flow. In addition, not only notebook PCs, but also various kinds of electronic devices such as game machines, DVD recorders, DVD players, hard disk recorders, and the like, are required to reduce the size and thickness of devices from the effective use of the installation space.

In such a device, necessary functions and unnecessary functions may exist depending on the grade of the device (for example, standard and high-end models, etc.) and the destination (for example, a domestic object and a foreign object). It is conceivable to mount even unnecessary functions and disable them, but doing so may lead to larger parts and higher prices. In particular, when there are a plurality of parts or units that need to be provided with holes in the housing as a whole, and a plurality of parts do not need to be mounted depending on the grade or destination, the installation of the holes affects the appearance. Making it impossible has problems, and unnecessary holes are a design problem.

Here, although Patent Document 1 proposes a technique for mounting any one of a plurality of types of display panels on a notebook PC, it relates to the mounting of components within the same kind of display panel, and the mounting of other kinds of components. There is no mention of.

In addition, Patent Document 2 discloses a MODEM module or a LAN module on the same type of printed board for the purpose of realizing the improvement of mass productivity when manufacturing both a built-in MODEM type notebook PC and a built-in LAN type notebook PC. A structure which can be attached is proposed. Although reference is made here to the attachment of the other modules, the MODEM module and the LAN module, they are not visually recognized from the outside, so that a module containing both functions can be manufactured and mounted so that only one side can be used. Also, the randomness in layout design is high.

In addition, Patent Document 3 proposes a notebook PC equipped with two types of display panels. There is no concept of selecting whether to mount according to the grade or the destination.

[Battery unit and speaker]

Fig. 10 is a perspective view showing the main body unit 20 of the notebook PC 10 shown in Figs. 1 to 4 from the back side with respect to the top surface on which the keyboard 21 is placed, and Fig. 11 is a dashed-dotted line in Fig. 10. 12 is an enlarged view of a portion of the circle R2 shown, and FIG. 12 is a perspective view showing the main body unit 20 of the notebook PC 10 showing the perspective views in FIGS. 1 to 4 from the upper surface side where the keyboard 21 is arranged, and FIG. 13. Is an enlarged view of the circle R3 part shown by a dashed-dotted line in FIG. Here, FIG. 10 and FIG. 12 show an exploded perspective view of the battery unit 27 detached from the main unit 20, and FIG. 11 shows the surface of the battery mounting portion side of the housing portion on which the speaker is mounted. 13, the mounting cross section of the battery unit 27 to the main body unit 20 is shown.

As described above, the battery mounting portion 271 that is mounted to the inside of the hinge portion 40 of the main body unit 20 so that the battery unit 27 that is responsible for supplying power to the respective portions of the notebook PC is detachable. Formed. The battery unit 27 is a substantially rectangular parallelepiped, has a connector having at least one power supply terminal on one side in the longitudinal direction thereof, and incorporates a plurality of battery cells connected to the connector in the case. The battery unit 27 slides from the back side of the main body unit 20 and is inserted into the battery mounting portion 271 of the main body unit 20 so as to be attached to the main body unit 20 in a state where both connectors are connected. On both sides of the battery mounting portion 271, speakers 26 for outputting sound toward the outside are arranged.

Here, the housing part which supports the speaker 26 of the main body unit 20 is formed in the shape which protruded toward the inner side of the main body unit 20, This housing part is a battery attached to the battery mounting part 271. It protrudes to the position which forms substantially the same surface as the unit 27, and in the state in which the battery unit 27 is attached to the battery mounting part 271, the housing part which supports the speaker 26, and the battery unit 27 are approximately It is a shape forming the same surface. That is, the part of the housing which supports the speaker 26 of the main body unit 20 is not covered with the display unit 30 when the display unit 30 is closed with respect to the main body unit 20. )

Conventionally, the battery unit is mounted inside the main body unit in a state where only the battery unit protrudes from the housing of the main body unit, so that only about half of the battery unit can be attached to the main body unit to make it feel unstable, or during transportation. The connector coupling portion of the main body unit and the battery unit has a load caused by the weight of the battery unit itself, which is easily broken, or has a structure in which the battery unit is damaged by hitting something during transportation. In this case, since the housing part supporting the speaker 26 protrudes to the same level as the battery unit 27, and the battery unit 27 is attached to the battery mounting part 271, the battery unit 27 is almost the same plane. The feeling of stability at the time of attachment of the 27 is improved. Moreover, this structure eliminates the load by the weight of the battery unit 27 in the connector connection part of a main body unit and a battery unit.

In addition, long grooves 273 (see FIG. 13) are formed on both side surfaces of the battery unit 27. The elongated groove 273 is fitted into the protrusion 272 (see Fig. 11) formed on the surface of the battery mounting portion 271 side of the housing portion where the speaker 26 of the main body unit 20 is disposed. The winning groove 273 extends to almost the entire width of the battery unit 27, and therefore, not only the sense of stability but also the battery unit 27 is actually supported by the main body unit 20. In addition, the long grooves 273 (the entire width of the battery unit 27) are supported by the battery unit 27, and the long grooves 273 are also connected to the connector by the weight of the battery unit 27 itself. Contributes to relieving the load stress.

11, the protrusion part 272 which enters the elongate groove 273 of the side surface of the battery unit 27 is divided into two parts 272a and 272b. When detaching the battery unit 27 attached to the battery mounting part 271 from the battery mounting part 271, the claw which slides the two operation members 274 shown in FIG. 10 to the protrusion part 272 is engaged. ) (Not shown) is pulled inside the battery unit 27 and removed. At this time, since the protrusion 272 is divided into two parts 272a and 272b, when the claw is pulled out to remove the battery unit 27, the claw pops out of the battery unit 27 by a spring. Since it is pressurized in the exiting direction, as soon as one part 272b is overcome, it enters between two parts 272a and 272b, and is caught by one part 272a again, and it is in a state which does not fall out there once. By operating the operation member 274 again, the claw is pulled again, and the battery unit 27 is pulled out again, so that the battery unit 27 is finally removed from the battery mounting part 271. Since the structure requires such two stages of detachment operation, an accident such as the battery unit 27 suddenly falls out and falls when detaching is prevented.
