ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention mainly relates to personal type home facsimile apparatuses.
2. Description of the Related Art
Recently, with respect to the recording system for a facsimile apparatus, there is a growing demand for a plain paper recording system which transfers to plain paper instead of a thermosensible paper recording system which uses rolled thermosensible paper. As the recording section for this plain paper there are a laser system and thermal transfer system, etc.
The laser system is used for a large facsimile apparatus mainly for business use. However, since it is technically difficult to reduce the size of the laser system, facsimile apparatuses with a small plain paper recording system mainly uses the thermal transfer system.
A conventional facsimile apparatus with the thermal transfer system houses the ink film in an ink film cassette and the main unit contains a space to install the ink film cassette.
FIG. 1
is a perspective view showing an example of ink film cassette in the conventional thermal transfer system facsimile apparatus.
In
FIG. 1
, the ink film cassette has feeding reel case
91
on one end and winding reel case
92
on the other. These two cases are assembled by combining upper frame
93
and lower frame
94
molded with synthetic resin, etc.
Upper frame
93
and lower frame
94
are provided with openings
95
and
96
for only those parts necessary for recording transcription to minimize the exposure of ink film
97
.
Housing the ink film in such an ink film cassette allows the user to carry it with ease and makes it possible to wind the ink film stably.
However, the conventional facsimile apparatus with the ink recording system requires a large space to house the ink film cassette itself, which has been an obstacle to downsizing.
SUMMARY OF THE INVENTION
An objective of the present invention is to implement the downsizing of facsimile apparatuses with an ink and plain paper recording system.
The present invention achieves the objective above by constructing an ink film unit with a feeding reel wrapped with an ink film, winding reel that winds up said ink film and a pair of tabular ink film holders that hold the both ends of said feeding reel and said winding reel in a pivotable manner and providing the facsimile apparatus with housing grooves to house and position said ink film holder and U-figured holders that hold the feeding reel and winding reel in a pivotable manner.
