ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a housing for an AC adapter in an electric instrument such as a printer.
BACKGROUND OF THE INVENTION
AC adapters for supplying a direct current to an electric instrument are known.
Further, it is known to provide an electric instrument including a small size instrument without an AC adapter therein, wherein the AC adapter is separately positioned where the AC adapter is concealed.
FIG. 5
shows a conventional printer and a conventional AC adapter, based on the above described desire.
An AC adapter

A DC cord

a
of the DC cord

is connected to a socket

of a printer. The AC adapter
9
converts an AC to a DC, for example, 100 volts AC to 25 volts DC.
In the conventional printer, the exposed AC adapter
9
deteriorates the appearance of the printer when there is no place for concealing the AC adapter. In addition, the adapter occupies a space to decrease the area for the printer.
Therefore, there is a need in the art for an AC adapter that can be mounted in the printer even if the size of the printer becomes somewhat large.
SUMMARY OF THE INVENTION
Accordingly an object of the present invention is to provide a housing for mounting an AC adapter in an electric instrument, thereby the adapter does not deteriorate the electric instrument and reduce the space for the instrument.
According to the present invention, there is provided a housing for an AC adapter in an electric instrument comprising, a main housing in which an electric instrument is mounted, a sub-housing in which an AC adapter is mounted, the sub-housing being detachably engaged with the main housing. The sub-housing is attached to an underside of the electric instrument. The AC adapter is removably mounted in the sub-housing.
These and other objects and features of the present invention will become more apparent from the following detailed description with reference to the accompanying drawings.
