At this time, the battery housing 2 is pushed down toward the bottom side of the case main body 1 by the guide pins 14 fitted in the guide grooves 11. Thus, when the single-type battery T1 is accommodated, the guide pin 14 of the case body 1 is pressed against the end of the guide groove 11 by the urging force of the dual-purpose negative electrode 18a in the dual-purpose positive electrode 7a direction. 2 is fixed in the first accommodation position.

  In the above-described first housing position, when the single-type batteries T1 are stored in series, as shown in FIG. 6, the two single-type batteries T1 are combined with the positive electrode 7a of the battery container 2 and the case main body 1. The battery cover 3 is housed in the single housing portion 5a between the battery negative electrode 18a and the lower portion of the outer peripheral surface thereof is supported by the support 19 of the case body 1 as shown in FIG. The holding part 20a holds and accommodates the upper part of the outer peripheral surface of the single-type battery T1. As a result, the battery positive electrode of the single-type battery T1 is connected to the positive electrode 7a, the positive electrode terminal 15 and the elastic electrode (not shown), and the battery negative electrode is connected to the negative electrode 18a. Power is supplied to the circuit board from a series single-type battery T1 connected to the board.

  Further, in the case where the AA batteries T2 are accommodated in series at the second accommodation position, as shown in FIG. 8, the two AA batteries T2 are combined with the dual positive electrode 7a of the battery housing 2 and the case body 1. The single negative electrode 18a is accommodated in the single 2 accommodating portion 5b, and the upper portion of the outer peripheral surface is held and accommodated by the first holding portion 20a of the battery cover 3 as shown in FIG. As a result, the battery positive electrode of the AA battery T2 is connected to the positive electrode 7a, the positive electrode terminal 15, the elastic electrode (not shown), and the battery negative electrode is connected to the negative electrode 18a. Power is supplied from a single AA battery T2 connected to the substrate and connected in series to the circuit substrate.

  Further, when the AA batteries T3 are accommodated in series at the second accommodation position, as shown in FIG. 10, the two AA batteries T3 are separated from the dedicated positive electrode 7b of the battery housing 2 and the case body 1. The AA housing portion 5c between the dedicated negative electrode 18b and the outer peripheral surface is held and housed by the restraining portion 16 and the second holding portion 20b of the battery cover 3 as shown in FIG. As a result, the battery positive electrode of the AA battery T3 is provided via the dedicated positive electrode 7b, the positive electrode terminal 15 and the elastic electrode (not shown), and the battery negative electrode is provided via the dedicated negative electrode 18b. Power is supplied from a series AA battery T3 to the circuit board and connected to the circuit board.

  As described above, in this embodiment, the single storage unit 5a that stores the single battery T1 is disposed at the top of the battery housing 2 in the depth direction, and the single battery is provided at the bottom of the single storage unit 5a. An AA accommodating part 5b for accommodating the battery T2 is disposed, and an AA accommodating part 5c for accommodating the AA battery T3 is disposed adjacent to the sides of the AA accommodating part 5a and the AA accommodating part 5b. As shown in FIG. 2, since the outer peripheral surfaces of the AA battery T1, the AA battery T2, and the AA battery T3 housed in each housing part 5 are configured to overlap, When the battery T1 is accommodated, other batteries cannot be accommodated. Similarly, when the AA battery T2 is accommodated or when the AA battery T3 is accommodated, other batteries cannot be accommodated. 5 can prevent erroneous storage of batteries of other battery types, that is, regular storage To 5, it can be accurately accommodated without hesitation the battery of the corresponding cell format.

  Moreover, in the 1st accommodation position (FIG. 4) which accommodates the single 1 type battery T1, the space | interval of the positive electrode 7 of the battery container 2 and the negative electrode 18 of the case main body 1 matched the wide single battery T1. Therefore, when either the AA battery T2 or the AA battery T3, which is shorter than the AA battery T1, is accommodated, it is between the positive electrode 7 and the negative electrode 18 that are contacts. In this case, the user cannot easily energize and cannot supply power, so that the user can easily recognize the erroneous accommodation, and the erroneous accommodation of the batteries of other battery types in the accommodating portions 5 having different battery types can be prevented.

  Similarly, in the second accommodation position (FIG. 5) for accommodating the AA battery T2 or the AA battery T3, the AA battery T1 having a longer length than each battery can be accommodated in the battery housing 2. Therefore, erroneous storage of the battery can be prevented. At this time, the AA battery 5 cannot be accommodated in the AA accommodating part 5c due to the shape of the circular arc concave surface and the restraining part 16, and the AA battery T3 is to be accommodated in the AA accommodating part 5b. Since the diameter of the arcuate concave surface of the A2 accommodating part 5b is larger than the outer diameter of the AA battery T3, the AA battery enters the opening 6 formed at the bottom of the AA accommodating part 5b of the battery accommodating body 2. When T3 falls, it is not possible to energize between the positive electrode 7 and the negative electrode 18, and it is possible to prevent erroneous storage of batteries of other battery types in the storage portions 5 of different battery types.

Furthermore, in the present embodiment, the switching of the position of the battery housing 2 for housing the AA battery T1, the AA battery T2, and the AA battery T3 is performed between the first housing position and the second housing position. The accommodation preparation is completed with only two modes and two motions, and the operability can be improved and simplified in the switching work.
Furthermore, the battery housing case having the above-described configuration is very wasteful as a battery housing space, and a simple, lightweight and compact battery housing case can be installed in the apparatus.

  Moreover, since it is the structure which did not require attachment or detachment of the battery accommodating body 2, it can prevent the removal part and the accompanying damage and loss. In addition, it is possible to reduce the number of components in housing the battery and improve the assembling workability associated therewith. As a result, it is possible to greatly contribute to improving the quality of the apparatus.

  As described above, since the battery housing case of the present embodiment has a function of preventing erroneous housing of batteries of different battery types, it is not limited to electronics-related devices such as communication devices, and corporations such as acoustic devices and toys. In products used by a large number of unspecified users such as individuals, when batteries of different sizes are used as the power supply and only one type of battery is stored in series, It can be applied to any product that requires a function that cannot accommodate batteries at the same time.

As described above, in this embodiment, the AA battery T1, the AA battery T2, and the AA battery T3 accommodated in the AA, AA, and AA accommodation units are included. Each of the outer peripheral surfaces is configured to overlap, and at the first accommodation position where the single-type battery T1 is accommodated between the dual-purpose positive electrode and the dual-purpose negative electrode, the dual-purpose positive electrode of the battery container and the dual-use negative electrode of the case body In the second accommodation position for accommodating the AA or AA batteries in a wide interval that matches the AA batteries T1, the dual positive electrode and the dual negative electrode for accommodating the AA batteries T2 Since the interval between the dedicated positive electrode for accommodating the AA battery T3 and the dedicated negative electrode is set to a narrow interval suitable for the AA battery T3, the distance between the AA battery T3 and the dedicated battery is different. In a battery housing case that allows the use of a battery of a different type, other storage units with different battery types It is possible to prevent erroneous accommodating batteries pond format.
In the above embodiment, the case where two batteries are accommodated in series has been described as an example, but the number of batteries accommodated may be one, or three or more batteries may be accommodated in series. May be.
