- engagement parts 203b and 203b, with which the engagement pieces 205a and 205a are engaged, are placed in the peripheral area of the insertion opening 203a to the device main unit 202.
- the plug body 206 is formed in roughly an equivalent shape as the combined size AA battery 204 and cover member 205.
- it comprises a battery-form part 207 having roughly the same form as the size AA battery 204 and cover part 208, which is provided on the cathode side of this battery- form part 207 having roughly the same form as the aforesaid cover member 205.
- An anode 207a which is in contact with a positive power terminal (not shown) placed inside the battery housing part 203, is provided on the battery-form part 207.
- a lid part 208 is provided with engagement pieces 208a and 208a in positions corresponding to the engagement pieces 205a and 205a of the cover member 205.
- a power line 191 leads from the outer face of the cover part 208 and is connected to an external power source. Additionally, wiring (not shown) connecting to the device main unit 202 side is provided on the cover part 208. Otherwise, the structure and operation are similar to those in Example 1 described above.
- Example 7 In the examples described above, examples in which a commercial power supply is used as the external power source were described, but a standard automobile cigarette lighter socket, or sources other than a commercial power supply may be used as the external power source.
- a commercial power supply is used as the external power source
- a standard automobile cigarette lighter socket, or sources other than a commercial power supply may be used as the external power source.
- an electrical product using a size AA battery was discussed, but of course the present invention may also be applied to electrical products which use dry power cells of varying sizes such as size C and size D batteries.
- the present invention offers the highly desirable effect of reducing the size of the device main unit and cost while increasing reliability in a device which is able to supply power from an external source to a battery terminal in the main unit of the device
