[0002]

2. Description of the Related Art A small facsimile apparatus has been proposed. Referring to the drawings, the recording unit;
The configuration of the document reading unit will be briefly described.

FIG. 13 is a cross-sectional view of a conventional facsimile machine, which is an example of a configuration that is considered to be the most compact and flat at present. In this drawing, a first opening 205 is formed near the edge of the upper surface of the housing cover 200 also serving as a housing, and a second opening 204 is formed near the inner side (rear side) of the housing. Cover 200
A discharge port 205 is formed on the front surface of.

In the above configuration, the original G is inserted with the reading surface downward through the first opening 205, and is rotated in a state where the contact type line image sensor 12 is urged against the contact type line image sensor 12. Dynamically driven first
The sheet is held between the urging rollers 13 and is conveyed and discharged from the discharge port 203.

On the other hand, on the back side of the upper surface of the housing cover 200, as shown in the figure, a roll-shaped recording paper KR made of heat-sensitive paper is held rotatably and replaceably in the direction of the arrow. The recording surface of the line thermal head 14 that constitutes the recording section of the first embodiment has a coloring surface facing the recording section, and the second biasing roller 15 that is rotated and driven in a biased state with respect to the line thermal head 14 To discharge the recording paper through the second opening 204 to the outside after recording.

With the above configuration, the thickness of the housing 200 is reduced so that the reading unit and the recording unit do not overlap in the thickness direction of the housing cover 200.

[0007]

However, in the facsimile apparatus described above, in order to reduce the thickness of the housing, a roll of recording paper KR is provided between the reading unit and the recording unit. As a result, the size of the housing in the front-rear depth direction has a problem that the depth cannot be reduced because at least an extra amount of the roll-shaped recording paper is required.

In the above facsimile apparatus,
In order to use a portable facsimile machine with a battery for its power supply, for example, a so-called battery pack will be used. However, since the battery pack is usually detachable outside the housing, There is a problem that the outer shape of the device becomes larger.

According to the facsimile apparatus described above,
Since only roll-shaped recording paper is used as recording paper, there is a problem that, for example, a so-called heat-sensitive recording paper of A4 size so-called cut paper cannot be loaded in the recording unit. In other words, in order to be able to load such a cut sheet into the recording unit, the operation becomes very troublesome, such as loading the cut sheet after removing the roll-shaped recording sheet, so it is practically impossible. It is. On the other hand, when a dedicated opening for inserting a cut sheet is newly provided near, for example, the above-described first opening, an opening having a longitudinal dimension of at least A4 lateral dimension and a first opening are provided. Since it is not possible to guarantee the strength of the rod-shaped partition formed between the sheet and the sheet, it is practically impossible to set a cut sheet.

Accordingly, the present invention has been made in view of the above-mentioned problems, and an object of the present invention is to make it possible to selectively use a cut sheet and a roll-shaped recording sheet, and to make the apparatus compact and flat. Another object of the present invention is to provide a small-sized facsimile apparatus that can easily attach and detach a power supply battery when a power supply battery is used as a portable facsimile apparatus.

While being conveyed in two directions, the roll paper K2 in which the thermal paper is made into a roll is conveyed / discharged from the rear side of the first opening 3 to the outside in the direction of arrow B2 in the drawing.

Next, FIG. 8A is a cross-sectional view of the roll sheet holder, and FIG. 8B is a cross-sectional view of FIG.
First, in (a), the roll sheet holder 40 is formed continuously from a base portion 44 for accommodating the roll paper K2 wound around the outer periphery of the core KT as shown in the figure, and a right edge portion of the base portion 44. The mounting means 46 provided is used as a base. One end of the butterfly 48 is fixed to the left edge (rear end) of the base 44, and the lid 45, to which the end 45b is fixed to the other end of the butterfly 48, is moved in the direction of arrow H1 in the figure. It can be opened and closed freely. The tip portion 45a of the lid portion 45 has a length sufficient to cover the second opening 4 of the small facsimile machine 1, and has a stopper 50 integrally formed on the back side thereof. The lid is held at the opening 4 so that the lid can be held in a closed state. On the other hand, the above-described mounting portion 46
