The charging device 1 is constituted by the rotor 4 which is supported and is rotatable in the direction N facing the main body 2. The terminals 8 and 9 on which the electrodes of the rechargeable battery E abut are provided on the wall surface of the main body 2 facing the rotor 4, and the rotor 4 is provided with a plurality of wall surfaces 11 and 12 facing the main body 2 by the rotation thereof. And the terminal portions 8 and 9 of the main body portion 2 are provided on the respective wall surfaces 11 and 12.
Terminal portions 13 to 16 facing each other are provided, and the terminal portions 8 and 9 of the main body portion 2 and the terminal portions of the respective wall surfaces 11 and 12 are provided.
The distances L1 and L2 of 13 to 16 are different.

(Operation) According to the above configuration, the rotor 4 is rotated to move the wall surface 1 thereof.
The terminals 13 to 16 provided on the terminals 1 and 12 are connected to the terminals 8 and 9 of the main body 2.
Then, the rechargeable battery E is mounted between the two terminal portions, and the plug blade 6 is inserted into the outlet to charge the rechargeable battery E. In this case, by rotating the rotor 4 in accordance with the size of the rechargeable battery E, the main body of the terminal parts 13 and 14 or the terminal parts 15 and 16 having the distances L1 and L2 that match the size of the rechargeable battery E are provided. The rechargeable battery E is attached to the charging device 1 so as to face the terminal portions 8 and 9 of the portion 2.

(Embodiment 1) Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of the charging device, and FIG. 2 is a side view of the same. The charging device 1 includes a box-shaped main body portion 2 and a pair of left and right extending straight from both side portions of the main body portion 2. Extension 3,
3 and a rotor 4 rotatably supported in a direction N facing the main body 2 between the extending portions 3, 3. Charging plug blades 6, 6 are provided on the side wall of the main body 2 so as to project and retract, and the plug blade is provided on the rear surface thereof.
6 and 6 projecting and retracting operation buttons 7 are provided. Further, a positive terminal portion 8 and a negative terminal portion 9 with which the electrodes of the rechargeable battery abut are provided on the front surface facing the rotor 4 so that a plurality of rechargeable batteries can be charged at the same time. . Further, charging means such as a charging circuit section and a transformer is built in the main body section 2.

The rotor 4 is substantially box-shaped and has a plurality of wall surfaces 11 and 12 facing the main body 2 by rotating in the direction N, and each of the wall surfaces 11 and 12 has the main body 2 Terminal portions 13a, 13b, 14a, 14b, 15a, 15b, 16a, 16b corresponding to the terminal portions 8, 9 are provided respectively. The terminal portions 13 and 14 are formed of a single conductive plate. Reference numerals 17 and 23 are receivers for the rechargeable battery E. 18
Is a lock button provided on the side wall of the rotor 4, and 19 is an engaging opening of the lock button 18 provided at the tip of the arm 3. The rotor 4 is rotated in the direction N after the lock button 18 is disengaged from the opening 19, and by engaging the button 18 with the opening 19, the rotor 4 is locked so as not to rotate. The rotation lock means is a well-known means.

Here, as shown in FIG. 1, with the wall surface 11 facing the main body portion 2, the terminal portions 8 and 9 of the main body portion 2 and the terminal portion 1 of the wall surface 11 are
The distance L1 of 3,14 is a length at which the AA rechargeable battery E1 can be charged. Further, as shown in FIG.
In the state where the wall surface 12 is opposed to the main body portion 2 by rotating, the distance L2 becomes a length at which the AAA rechargeable battery E2 can be charged. In this case, the rear surface 20 for the wall surface 11 and the rear surface for the wall surface 12
In order not to make a mistake in the type of rechargeable battery that can be charged by the user, for example, by writing “AA” and “AAA” in 21 respectively, the wall surfaces 20 and 21 are respectively charged with AA rechargeable batteries E1 or E1. It can be used as the display surface of the AAA rechargeable battery E2. Reference numerals 24a and 24b denote charging indicator lamps provided on the upper surface of the main body 2 to indicate that the rechargeable batteries mounted on the left and right sides are being charged.

The present apparatus has the above-mentioned configuration, and the handling will be described next.

FIG. 1 shows a state in which a slightly larger AA rechargeable battery E1 is being charged. In this case, the first wall surface 11 faces the main body portion 2, and a plurality of rechargeable batteries are provided between both terminal portions 8, 9 and 13, 14.
The rechargeable battery E1 is charged by mounting the E1 and projecting the plug blades 6 and 6 and inserting it into an outlet (not shown). When charging the small size AAA rechargeable battery E2, the rotor 4 is rotated to move the terminal portion 1 of the second wall surface 12 as shown in FIG.
5 and 16 are opposed to the main body 2 and a plurality of rechargeable batteries E2
Put on and charge. In this case, the rotation direction of the rotor 4 is set to the above-mentioned direction N which is different from the projecting direction of the plug blades 6, 6 so that the exposed surfaces of the plug blades 6, 6 and the exposed surfaces of the terminals 13 to 16 are different. Can be a face and therefore a plug blade 6,
It is possible to prevent the terminals 13 to 16 of the rotor 4 from coming into contact with the surface of the outlet and causing a short circuit when the 6 is inserted into the outlet and charged.

(Embodiment 2) FIG. 3 shows another example of the display means, in which the lock button 18 is formed with an arrow 25, and the wall surface of the extending portion 3 is "AA" or "AA". The character "" is described. Therefore, the user can confirm the type of rechargeable battery that can be charged by the characters indicated by the arrow 25. In addition, in the structure shown in FIG. 4, a window portion 26 is formed in the extension portion 3, and the letters “single 3” and “single 4” are written on the side wall of the rotor 4,
From 26, by visually recognizing each character, the type of rechargeable battery that can be charged can be confirmed.

(Effects of the Invention) As described above, the charging device according to the present invention includes the main body 2 having the charging plug blade 6, the extending portion 3 extending from the main body 2, and the extending portion 3 And a rotor 4 which is rotatably supported by the rotor 4 and is rotatable in the direction N facing the main body 2.
The rechargeable battery E is attached to the wall surface of the main body 2 facing the rotor 4.
Terminal portions 8 and 9 with which the electrodes contact each other, and the rotor 4 is provided with a plurality of wall surfaces 11 and 12 facing the main body portion 2 due to the rotation thereof, and each of the wall surfaces 11 and 12 has the main body portion. The terminal portions 13 to 16 facing the two terminal portions 8 and 9 are provided respectively, and the distances L1 and L2 between the terminal portions 8 and 9 of the main body portion 2 and the terminal portions 13 to 16 of the respective wall surfaces 11 and 12 are provided.
