Further, the eject lever 16 is formed with a hook hole 17 at a position opposite to the position where it engages with the shaft portion 20. The elastic member 11 is hung on the hook hole 17 and the second hook portion 10 formed in the battery chamber 4. By this elastic member 11, the eject lever 16 is always urged downward (in the direction of removing the battery 3).

  By adopting such a configuration, when the member (battery cover 5) that locks the battery 3 from jumping out of the battery chamber 4 is lost (when the battery cover 5 is in the open state), the eject lever 16 Acts to discharge the battery 3 from the battery chamber 4.

  In the present embodiment, the shaft portion 20 is formed on the battery chamber 4 side and engaged with the eject lever 16. However, the shaft portion 20 is formed on the eject lever 16 side, and a hole is formed on the battery chamber 4 side. It is good also as a structure which gets engaged. Moreover, although the part which hangs the eject lever 16 and the elastic member 11 was demonstrated as the hook hole 17, it is not limited to a hook hole, For example, it is good also as providing a hook part like above-mentioned FIG. If the eject lever and the elastic member can be hooked, the configuration is free.

  Although not shown here, since the first contact surface 15 is provided by engaging with the eject lever 16, the first contact surface 15 is moved to the front side of the side surface of the battery chamber 4 shown in FIG. For this purpose, a groove portion is provided. Alternatively, as in the case of FIG. 3 and the like, a groove portion may be formed on the side surface on the side where the second hook portion 10 is provided, and the eject lever 16 may be penetrated through the groove portion to be movable.

  FIG. 6B shows a state in which the battery 3 is discharged from the battery chamber 4. With respect to FIG. 6A described above, the eject lever 16 is pushed down in the downward direction in FIG. 6 by the force of the elastic member 11, and the battery 3 is discharged. The battery 3 is discharged by the first contact surface 15 of the eject lever 16. At the same time, the eject lever 16 is stopped from discharging power (downward bias) to the battery 3 by a contact surface (not shown) on the battery chamber 4 side.

FIG. 7 is a diagram schematically showing the third battery housing case of the present embodiment.
In FIG. 7, a guide member 23 is formed in the battery chamber 4 in addition to the configuration of the first battery housing case. An eject lever 21 provided with a guide groove 22 so as to engage with the guide member 23 is disposed. The eject lever 21 is slidable along the guide groove 22.

  A first hook portion 9 is formed on the eject lever 21, and a second hook portion 10 is formed on the lower side of the battery chamber 4. An elastic member 11 such as a spring is hung on the first hook portion 9 and the second hook portion 10. By this elastic member 11, the eject lever 8 is always urged downward (in the direction of removing the battery 3). Further, the eject lever 21 is also provided with a first contact surface 15 and acts to discharge a battery (not shown).

FIG. 8 is a diagram schematically showing a fourth battery housing case of the present embodiment.
As a form of the fourth battery housing case, the battery chamber 4 is in a state capable of supporting two types of batteries. Here, a description will be given using a Li battery as the first battery and an AAA battery as the second battery.

  As a contact portion for the Li battery, a first contact portion 12, a second contact 13, and a third contact 14 are provided, and each contact portion contacts the Li battery to exchange power and signals. Moreover, as a contact part with respect to a AAA battery, the 1st AAA contact part 25 and the 2nd AAA contact part 26 contact a AAA battery, and exchanges a power supply, a signal, etc.

  In the internal structure shown in FIG. 8, it is impossible to dispose the coil spring 24 for discharging the battery separately from the contact portions as in the prior art. As described above, the coil spring 24 must absolutely avoid contact with each contact portion, but the configuration of the prior art cannot satisfy this configuration. On the other hand, in this embodiment, as shown in FIG. 8, since the eject lever 8 can be comprised very compactly, it can be arrange | positioned in a battery chamber.

  Conventionally, when two or more types of batteries are mounted in a battery chamber, a contact portion for taking out a power source and a signal from the battery is required. For example, in the current mainstream lithium secondary battery, a total of three locations are required, that is, two locations of the power source and one location for temperature detection. In the case of AAA batteries, two power sources are required. In the case of a battery chamber corresponding to both lithium secondary batteries and AAA batteries, a total of six contact portions are required.

  Here, when the battery insertion portion is viewed, the insertion area is limited, and most of the insertion portion inside the battery is occupied by the contact portion. Thereby, it becomes difficult to arrange the coil spring 24 for discharging the battery. The reason is that due to the nature of the coil spring 24, it is unavoidable that the coil spring 24 is slightly inclined and attached or deformed. In addition, if the coil spring 24 and each contact portion come into contact with each other, it may occur in a major accident such as smoke or fire, which is an important item that must be avoided.

  For the reasons described above, the space that must be provided when the coil spring 24 is disposed for discharging the battery must be large, and when two or more types of batteries are mounted in the battery chamber, the coil spring 24 is required. The placement itself becomes impossible.

  On the other hand, according to the present embodiment, since the elastic member 11 such as springs is not arranged in the battery chamber 4, the member for pushing out the battery (eject lever) can be configured very compactly, and two or more types can be formed. It becomes possible to form a battery discharge function corresponding to the storage of the battery.

  As described above, according to the battery housing case and the electronic device of the present embodiment, since there are no springs in the battery chamber, the user can grasp the battery that has popped out, so that various accidents related to attachment / detachment of the battery can be prevented, and Operability can be improved. Further, the eject lever for discharging the battery from the battery chamber can surely push out the battery, and does not occupy a large space in the battery chamber for arranging other parts. Therefore, the battery housing can be formed compactly.

  The battery housing of this embodiment can be applied not only to the digital camera and video camera described above, but also to an electronic device having a configuration in which a battery is attached and detached, such as a headphone stereo.
