Conventionally, in order to arrange interior parts compactly and without waste in the main body case 31, conventionally, circuit boards 46 and 47, each of which is a printed circuit board divided into two, are used as shown in FIG. A circuit board 46 is provided above the portion 36.
On the other hand, a circuit board 47 is arranged below the display section 41 and in front of the battery housing section 36, and these circuit boards 46,
47 were connected to each other by a connector 48 and a cable 49.

[0003]

As described above, conventionally,
Two circuit boards 46 and 47 are required, and the circuit board 4
A connector 48 and a cable 49 for connecting 6 and 47 to each other are required, and there is a disadvantage that the cost is increased.

Accordingly, an object of the present invention is to provide a small-sized electronic device having a display unit such as a portable liquid crystal television or the like by arranging interior parts compactly without dividing a circuit board to reduce costs and reduce size. It is to make it possible to achieve both.

First, FIG. 1 shows a schematic configuration of a portable liquid crystal television 10 as an example of a small electronic device to which the present invention is applied, 11 is a main body case, 12 is a front case, 13 is a screen cover, and 14 is a battery housing. , 15 is a rear case, 16 is a push plate portion, 17 is a battery cover, 21 is a display portion, 22 is an LCD (liquid crystal display device), 23 is a fluorescent tube, 24 is a reflection plate, 25 is a diffusion plate,
6 is a circuit board, and B1, B2, B3 and B4 are batteries.

The main body case 11 is a thin box having a front case 12, a rear case 15, and a battery cover 17 made of resin molded parts. Front case 12
Indicates a screen cover 1 on a screen window (not shown) formed in the upper half thereof.
3 and an L-shaped battery accommodating portion 14 which is open to the front side in the lower half. 14a is an upper wall portion of the battery housing 14, 14b is a vertical wall portion, and 14c is a rear upper wall portion.

The rear case 15 is combined with the front case 12 and has a lower wall 15a of the battery housing 14. The lower wall 15a of the rear case 15, the upper wall 14c, A push plate portion 16 is formed on the back surface between them. The battery cover 17 is attached to the front opening of the battery housing portion 14 and has a locking claw 17a for engaging with a locking hole 14d of the upper wall portion 14a at an upper end portion. The lower end has a locking claw 17b that contacts the upper surface.

In the main body case 11 having the above configuration, the display section 21 disposed in the upper half thereof is provided with an LCD 22.
, A fluorescent tube 23 spaced apart from the back side, a reflector 24 on the back side, and a diffusion plate 25 on the back side of the LCD 22. A circuit board 26 made of a single printed circuit board is arranged on the rear side in the main body case 11. That is, the circuit board 26 is disposed in front of the rear case 15 along the rear surface thereof, and the lower end of the circuit board 26 is located at the rear upper wall portion 14c of the L-shaped battery housing portion 14 in a side view.
Close above.

[0013] In the L-shaped battery storage section 14 in a side view, three batteries B1, B2, and B3 are stored in order from the top, and a back upper wall section 14c and a lower wall section 15 of the rear case 15 are housed.
One battery B4 is stored between the battery B4 and the battery a4. In addition, a locking claw 17a of the battery cover 17 is engaged with a locking hole 14d of the upper wall portion 14a of the front opening portion of the battery housing portion 14, and the upper surface of the lower wall portion 15a is The battery cover 17 is attached by bringing the locking claws 17b into contact.

FIG. 2 shows an example of the shape of the push plate 16 for taking out the battery B4 at the back. That is, as shown in FIG. 2A, for example, the push plate portion 16 at the lower rear side of the rear case 15 has a wide portion 162 at the tip of a narrow portion 161 extending from one side to the other side. 2B, or a plate having a hollow portion 163 around the periphery thereof, or as shown in FIG. 2B, a plate portion 165 that is uniform in the left-right direction is connected by upper continuous portions 166, 166, 166, and 166. It may be a shape having a hollow portion 167 around the periphery. By pressing such a push plate portion 16 with fingers as shown by arrows in FIG. 1, the battery B4 at the back in the L-shaped battery storage portion 14 in side view can be easily taken out to the front side.

In addition to providing an L-shaped battery storage section 14 in which the battery B4 is disposed in a side view and a single circuit board 26 disposed along the back side in the main body case 11, a conventional configuration is provided. There is no need to use divided circuit boards. Therefore, the cost can be reduced compared to the conventional one,
By arranging interior parts compactly, miniaturization can be achieved.

In the above embodiment, a portable liquid crystal television is used. However, the present invention is not limited to this, and other small electronic devices having a display unit may be used. In addition, the shapes of the battery housing portion and the push plate portion are also arbitrary, and it goes without saying that specific detailed structures and the like can be appropriately changed.

[0015]

As described above, according to the small electronic device of the present invention, by arranging the battery housing along one surface provided with the display section in the main body case, the other surface in the main body case is provided. Since the space for disposing the circuit board is provided along the side, the interior components can be compactly arranged without dividing the circuit board, and thus both cost reduction and miniaturization can be achieved. And this
Move a part of the pond storage section from one side to the other
Extend to the end, and further with the other part of the battery compartment.
Part of the circuit board overlaps in the thickness direction of the body case.
As a result, the space can be used effectively. In addition, if the push plate part for pushing a battery to one surface side is formed in the edge part of the other surface side of the main body case like Claim 2, by pushing the push plate part with a finger | toe,
