ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an electronic equipment employing a battery as a power supply.
An electronic equipment such as a small-sized cassette player, a disk player, a single-unit video camera-recorder, a portable telephone or the like employs a battery as a power supply therefor. A secondary battery which can be repeatedly charged, e.g., a block-shaped battery such as a nickel-cadmium battery package, a lithium battery package or the like is employed as a power supply. A large number of electronic equipments employing batteries as power supplies therefor employ an arrangement in which a battery housing portion having a battery terminal is formed in an equipment casing and a battery is housed in the battery housing portion to be electrically connected to the battery terminal. Some single-unit video camera-recorders are arranged such that a battery terminal is disposed on the side of an outer surface of an equipment casing, particularly on a rear surface side, and a battery is electrically connected to the battery terminal with being engaged and attached to the battery terminal.
Moreover, some electronic equipments are arranged such that a battery housing case is formed independently of an equipment casing and the battery housing case housing a battery is attached to the equipment body when the battery is employed as a power supply.
Since the electronic equipment employing a battery as a power supply therefor and housing the battery in a battery housing portion in its equipment casing uses a block-shaped battery, the electronic equipment has a larger battery housing portion in its equipment casing and consequently the whole casing becomes larger-sized. Additionally, a battery to be used therefor must have a predetermined shape, which prevents batteries having different capacities from being used simultaneously.
An electronic equipment having a battery terminal disposed on the outer surface side of its equipment casing encounters disadvantages that, when a battery is not used, the battery terminal is exposed to the outside, which aggravates an appearance of the electronic equipment and may damage the battery terminal. Moreover, an electronic equipment having a battery housing case formed independently of its equipment casing and attached to the equipment casing when a battery is used, encounters disadvantages that the whole equipment becomes large-sized upon use of the battery, which leads to inconvenience in carrying the electronic equipment and particularly in portability. Also, in this case, a battery to be used therefor must have a predetermined shape, which prevents batteries having different capacities from being used simultaneously.
SUMMARY OF THE INVENTION
In view of such aspects, it is an object of the present invention to provide an electronic equipment which employs a battery as a power supply therefor,in which, when a battery is not employed, an equipment casing can become compact and battery terminals cannot be seen from the outside and which allows the batteries having different capacities to be employed therefor as long as each of them has common terminal portions.
According to a first aspect of the present invention, in an electronic equipment employing a battery as a power source, a battery terminal connected to a battery is disposed so as to be moved into and out of an equipment casing, and when the battery terminal is moved to the outside of the equipment casing, then the battery is connected at the outside of the equipment casing.
According to a second aspect of the present invention, a battery terminal case having the battery terminal is fitted to the equipment casing so as to be drawn therefrom by rotating or sliding the battery terminal case, and when the battery terminal case is projected toward the outside, then the battery is connected at the outside of the equipment casing.
According to a third aspect of the present invention, one terminal of the battery terminal is fixed on the equipment casing, and the other terminal of thereof is fixed on the battery terminal case fitted to the equipment casing so as to be drawn therefrom by rotating or sliding the battery terminal case. When the terminal case is projected toward the outside, then the battery being connected at the outside of the equipment casing.
According to the electronic equipment of the present invention thus arranged, since, when the battery is used, the battery terminal is moved to the outside of the equipment casing and then the battery is disposed and connected, it is possible to employ batteries having different sizes and different capacities as long as each of them has common terminal portions. Since, when the battery is not used, the battery terminal is housed in the equipment casing, the outer appearance of the electronic equipment is improved and the equipment casing thereof can become compact as compared with that of a battery incorporated type electronic equipment.
