Supply to. The supply of power is stopped when the battery is in the charging completed state.

[Problems to be Solved by the Invention] In the conventional device as described above, the battery mounting part and the AC adapter mounting part are separated into a main body and a lid part, and are connected to each other by lead wires, and a charging control part is provided on one side. However, since the structure has such a control circuit, there is a problem that breakage of a lead wire or the like occurs due to opening and closing of the lid, and assembly is troublesome due to the complicated structure.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a highly reliable battery charger which has a simplified structure and is free from the risk of disconnection of lead wires and the like.

[Means for Solving Problems] A battery charger of the present invention comprises a device main body and a lid that can be opened and closed with respect to the upper surface of the device main body. A battery charging device that supports a built-in battery pack and charges the battery, wherein a battery contact that is in electrical contact with the battery, and a battery pack mounted near the battery contact for mounting the battery For electrical contact with the mounting rail and removable AC adapter
A first direction having an AC adapter contact and an AC adapter mounting rail provided in the vicinity of the AC adapter contact for mounting the AC adapter on the top surface of the device body, and substantially parallel to the top surface of the device body. While sliding the battery pack on the rail, the battery pack is mounted on the rail for mounting the battery and connected to the battery contact, and the AC is connected in a second direction substantially parallel to the upper surface of the apparatus main body and intersecting the first direction. The adapter is mounted on the AC adapter mounting rail while sliding and connected to the AC adapter contact, and a predetermined current is supplied from the AC adapter to the battery via the AC adapter contact and the battery contact. Thus, the battery is configured to be charged.

[Operation] With the above configuration, it is possible to charge the battery with high reliability with a simple configuration.

[Embodiment] FIGS. 1 to 4 are schematic views of a battery charging apparatus according to an embodiment of the present invention, FIG. 1 is a perspective view showing the entire apparatus, and FIG. 2 is a case lid. 3 is a perspective view of when the vehicle is closed, FIG.
4 and 5 are perspective views showing a usage state of the apparatus shown in FIG.

1 to 4, 12 is a lower body of the case of the charging device, 13 is an upper body of the case, 14 is a lid of the case, 15 is a printed circuit board, 16 is a contact base, and 17 is for an AC adapter. A contact, 18 is a contact for a battery, 19 is a rail for mounting a battery and an AC adapter, 20 is a hole for inserting the contact 17, 21 is a hole for inserting the contact 18, 22 is provided on the lid 14. The attached shafts 23a and 23b are recesses for sandwiching the shafts 22 provided in the upper body and the lower body of the charging device case.

Further, the same reference numerals as those in FIGS. 5 to 7 indicate the same or corresponding portions.

In FIG. 1, all contacts are directly attached to a charge control printed circuit board 15.
By overlapping and closely adhering to the upper body 13 of the case,
The contacts 17, 18 on the printed circuit board 15 are the holes 20, 21 in the upper body 13.
The AC adapter 9,
The battery packs 10 and 11 can be connected. Further, the case lid 14 is configured such that the shaft 22 is sandwiched between the recesses 23a and 23b of the case upper body 13 and the case lower body 12 so that the lid 14 can be opened and closed.

As shown in FIGS. 3 and 4, the battery packs 10, 11
The AC adapter 9 and the AC adapter 9 can be electrically connected to the charging device when the connection portions (not shown) provided on the back surfaces of the AC adapter 9 and the AC adapter 9 are slide-mounted via the mounting rails 19.

[Effects of the Invention] As described above, according to the present invention, the AC adapter is mounted in the direction intersecting the battery pack mounting direction. It is now possible to prevent battery damage. Further, since the battery pack and the AC adapter are attached to the rails provided on the upper surface of the apparatus main body, the battery packs having different shapes can be attached for charging. Further, it has become possible to provide a highly reliable battery charger which has a thin device, has a simple structure, and is free from the risk of disconnection of lead wires and the like.
