On the other hand, when using not only the electronic device 71 driven by a DC voltage but also the electronic device 77 driven by an AC voltage, the case body 9 having the DC / AC converter 10 is required together with the case body 2. . That is, in this case, the case body 9 is connected to the case body 1 via the connection bolt 58.
And the handle 30 is slidably fixed over a substantially central upper portion connecting the case bodies 1 and 9 to each other. Then, the back covers 27 and 56 of the case bodies 1 and 9 are opened, and the connectors 25 and 25
When the connectors 25 and 25A are connected to each other, the DC output from the battery output unit 2 is converted into an AC output by the inverter 54 in the DC / AC conversion output unit 10. At this time, when the plug 78 of the electronic device 77 is inserted into the AC outlet 61 and the main switch 65 is turned on, the power display section 63 is turned on, and the AC voltage from the inverter 54 is turned on.
Is supplied to the electronic device 77 via the. In addition to the electronic device 77, a DC voltage can be simultaneously supplied from the cigar socket 37 to the electronic device 71.

By operating the output conversion switch 66, the DC / AC output converter 10 can switch the output power in two stages according to the amount of power used by the electronic device 77. When the total power consumption of the battery 77 is insufficient with the lead storage battery 21 alone, the case body 6 further including the auxiliary power supply unit 5 is required. In this case, the case body 6 is attached and fixed to the left body 3A side of the case body 1 using the connecting bolt 46, and the case bodies 1, 6, 9 are integrated by connecting the connectors 24, 24A. It is possible to use it in a state in which

On the other hand, as a predetermined DC or AC voltage is supplied to the electronic devices 71 and 77, the lead storage battery 21 or the lead storage battery 41 gradually discharges, and the discharge time displayed on the LED display unit 36 is reduced. The remaining amount gradually decreases. In order to charge the discharged lead storage battery 21, the input plug 39 of the AC / DC conversion adapter 75 is connected to the input jack 39 while the main switch 38 is stopped discharging, and a predetermined power is supplied from the AC / DC conversion adapter 75. Is supplied, a DC voltage is applied to both ends of the lead storage battery 21. Also, when the cigar plug 26 is taken out of the storage chamber 23 instead of the AC / DC conversion adapter 75, and this cigar plug 26 is inserted into and connected to, for example, a cigar socket 74 of the vehicle 73, the voltage is applied to both ends of the lead storage battery 21. It can be charged by DC voltage. At this time,
When the connectors 24 and 24A are connected, a DC voltage is applied not only to the lead storage battery 21 of the battery output unit 2 but also to both ends of the lead storage battery 41 of the auxiliary power supply unit 5, and the charging rate during charging is indicated by the LED display unit 36. Displayed via.

As described above, according to the above-described embodiment, the secondary voltage output unit 2 for supplying a DC output, which contains the lead-acid battery 21,
By housing the DC / AC conversion output unit 10 for supplying an AC output that incorporates the inverter 54 in separate case bodies 1 and 9, the use condition on the output side is limited to the electronic device 71 driven by a DC voltage. In this case, the case body 1 provided with the secondary voltage output unit 2 can be used alone, and it is not necessary to carry the case body 9 provided with the DC / AC conversion output unit 10 each time. Therefore, by omitting the carrying of the case body 9 having unnecessary functions according to the use of the user, it is possible to reduce the weight of the entire apparatus, and it is possible to provide a power supply apparatus that is extremely easy to use practically. Further, by separately providing the case main body 6 having the function of the auxiliary power supply section 5, the case main body 6 provided with the auxiliary power supply section 5 can be connected by the connecting bolt 46 only when the electric power consumption of the electronic devices 71 and 77 is large. What is necessary is just to attach it to the case main body 1, and the factor of the cost increase by purchasing a complete apparatus separately like the conventional one can be removed.

Further, a secondary voltage output section 2 and an auxiliary power supply section 5

Such a mechanism can be prevented from hitting an object from the outside, and can have a drip-proof function to some extent.
Further, since the supply voltage to the connector 25A is 12 V DC, if a plug adapter (not shown) is connected to the connector 25A, the cigarette socket 74 of the vehicle is directly connected to the connector 25A to which the plug adapter is attached, so that the DC power is supplied. The case body 9 provided with the / AC conversion output unit 10 can be used alone. Therefore, even if the lead storage batteries 21 and 41 are completely discharged while the DC / AC conversion output unit 10 is being used, the DC / AC conversion output unit 10 can be continuously used.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention.
