The present invention relates to a battery pack, and more particularly to a battery pack that is made of a secondary battery and that is detachably attached to an electronic device. Summary of the Invention Σ The present invention is a system in which a power supply circuit is incorporated into a battery bag together with a secondary battery. This makes it possible to construct a circuit using only current circuits. [Prior Art] Portable VTRs, video cameras, etc. that are generally used outdoors cannot use commercial power from an outlet, so they are powered by a battery pack consisting of a secondary battery. In other words, a battery pack containing a built-in secondary battery is detachably attached to a VTR or camera, so that the VTR or camera can be operated at any location. τProblems to be Solved by the Invention] When a device is driven by a battery pack made of secondary batteries as described above, a power supply circuit that always outputs a constant voltage regardless of changes in the output voltage of the secondary batteries is required. is provided on the main body side, thereby preventing the influence of voltage fluctuations of the secondary battery and making it possible to use the charged power effectively to the maximum extent. Therefore, on the main body side, not only a small current circuit but also a power supply circuit through which a relatively large current flows coexist, which has the drawback of complicating circuit design and making shielding troublesome. The present invention has been made in view of these problems, and it is an object of the present invention to provide a battery pack that makes it possible to reduce the circuit on the electronic device main body side to only a microcurrent circuit, and that can be easily shielded. The purpose is to

[Embodiment Σ] The present invention will be described below with reference to an illustrated embodiment. FIG. 2 shows a VTR in which a battery bag according to an embodiment of the present invention is used, and a rectangular battery insertion hole 11 is provided on the outer surface of the cabinet of the VTR main body 10 constituting this VTR. A battery bag 12 is detachably inserted into the battery insertion hole 11. The battery back 12 is the first
As shown in the figure, it has a structure in which a secondary battery 13 made of a lithium battery or a nickel-cadmium battery is housed in a metal case and further insulated with an insulating material. As is clear from FIG. 1, a constant voltage circuit 14 consisting of an OC-OC converter is also incorporated into the battery pack 12. A stabilized power source, which is the output of the constant voltage circuit 14, is taken out from output terminals 21 and 22, and the battery bag 12 is further provided with a charging terminal 23. As described above, since the battery bag 12 for secondary batteries according to this embodiment incorporates the constant voltage circuit 14 together with the secondary battery 13, there is no need to provide the constant voltage circuit 14 on the VTR main body 10 side. For this purpose, the VTR body 1
It becomes possible to make the circuit within 0 only a minute current circuit. Therefore, the circuit design on the side of the VTR main body 10 becomes easy, and shielding can be done with a simple structure. Furthermore, since the constant voltage circuit 14 is built into the battery pack 12, the wiring between the battery 13 and the power supply circuit 14 can be significantly shortened. Also VTR
There is no need to provide the power supply circuit 14 on the main body 10 side, and it is sufficient to simply insert a current limiting fuse, and the main body 10 [
It becomes possible to reduce costs by 1tll. Further, since the constant voltage circuit 14 is not incorporated in the VTR body 10, there is an advantage that the acquisition time for safety Xff I is shortened. Next, a modification of the above embodiment will be explained with reference to FIG. The modification shown in FIG. 3 is one in which a voltage detection circuit 15 is added.
In addition to detecting the output voltage of the secondary battery 13, if the output voltage of the secondary battery 13 drops below a certain value, an output is generated at the alarm terminal 24, thereby indicating when it is time to replace the battery. This is to let you know. Therefore, according to this modification, it is possible to know the details of the secondary battery 13 in the battery pack 12 in advance, and thereby it is possible to prevent the secondary battery 13 from being discharged unexpectedly. Become. FIG. 4 shows yet another modification, in which a solar cell 16 is added in parallel with the secondary battery 13. The sun 16 is connected in series with a diode 17 for preventing backflow, and a series circuit of the solar cell 16 and the diode 17 is connected in parallel to the secondary battery 13. Note that the solar cell 16 is
The light receiving surface is exposed on the outer surface of the battery pack 12. Therefore, this battery pack 12 is
It becomes possible to easily charge the battery by simply removing it from the R main body 10 and standing it outdoors. Note that as the solar cell 16, for example, a battery such as an amorphous battery may be used. FIG. 5 shows another modified example in which a current limiting circuit 18 is connected in series to the output side of the constant voltage circuit 14. Note that the current limiting circuit 18 is
It may be constructed from a fuse or a breaker that does not use a fuse. By providing such a limiting circuit 18, it is possible to prevent excessive voltage or excessive current from being supplied to the VTR main body.
It becomes possible to reduce the burden on the circuit on the R main body 10 side. Further, according to such a configuration, there is no need to provide a current limiting circuit or a fuse on the VTR main body 10 side, thereby making it possible to further reduce the cost of the VTR main body 10. "Effects of the Invention" As described above, the present invention is such that a power supply circuit is incorporated into a battery pack together with a secondary battery. Therefore, according to the present invention, the circuit inside the electronic enclosure main body is configured to contain only a minute current circuit. This also brings about the advantage that it becomes possible to create a pseudo-circuit easily.
