Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a facsimile machine which can use a large-diameter roll of recording paper which cannot be stored in a recording paper storage chamber in a main body case.

[0002]

2. Description of the Related Art Generally, a recording paper accommodating chamber for accommodating a recording paper roll is provided in a main body case of a facsimile machine. A plurality of types of recording paper rolls having different diameters are commercially available. In recent years, a large number of commercially available small facsimile machines are provided with a recording paper storage chamber small enough to accommodate a recording paper roll having a small diameter.

In a small-sized facsimile apparatus, this small recording paper storage chamber is arranged on one side of the main body case, and an opening for replacing the recording paper roll is formed on one side surface of the main body case.
A side cover that opens and closes the opening is pivotally supported at the lower edge of the opening.

Further, in a small-sized facsimile apparatus, the side cover is connected to a thermal head through an interlocking mechanism and the side cover is closed so that the recording paper pulled out from the recording paper roll can be easily loaded manually. At times, the thermal head approaches the platen roller to a printable distance, and when the side cover is opened, the thermal head is separated from the platen roller by a predetermined distance larger than the printable distance.

[0005]

By the way, the reception frequency and the reception time are not determined by the size of the facsimile apparatus, but a small-diameter recording paper becomes expensive for a facsimile receiver having a large reception frequency and reception time. It is preferable to use a recording paper roll having a large diameter and to replace the recording paper roll less frequently than to frequently replace the roll.

In a small-sized facsimile apparatus, a space large enough for a large-diameter roll of recording paper to be placed on the upper side of the opened side cover can be provided, but when the side cover is opened, the thermal head is separated from the platen roller. Since it is in the open position, it is not possible to print on the recording paper, and eventually a large diameter recording paper roll that cannot be stored in the recording paper storage chamber cannot be used.

In view of the above circumstances, it is an object of the present invention to provide a facsimile apparatus which can use a large diameter recording paper roll which cannot be stored in the recording paper storage chamber in the main body case. .

[0008]

According to the present invention, a recording paper storage chamber is provided on one side of a main body case, and an opening for inserting a recording paper roll into the recording paper storage chamber is formed in the main body case. In a facsimile apparatus provided with a side cover that opens and closes the opening at the lower edge of the opening, and an interlocking mechanism that interlocks with the cover to move the thermal head forward and backward toward the platen roller. The following measures are taken to achieve this.

That is, in the first facsimile apparatus of the present invention, the opened side cover is also used as a table on which a recording paper roll having a diameter larger than that of the recording paper roll stored in the recording paper storage chamber is placed. A recording paper cover that can be disassembled is connected to this side cover so as to cover the large diameter recording paper roll placed on this side cover. This recording paper cover drives the interlocking mechanism to bring the thermal head close to the platen roller to a printable distance when the recording paper cover is located at the cover position.

The second facsimile apparatus of the present invention is
The side cover with the opening opened is also used as a table on which a recording paper roll having a diameter larger than that of the recording paper roll stored in the recording paper storage chamber is placed, and is configured to be horizontally expandable and contractable. The side cover is expanded and contracted in the horizontal direction to drive the interlocking mechanism to bring the thermal head closer to the platen roller to a printable distance.

[0011]

In the first facsimile apparatus of the present invention,
When the side cover is opened, first, as before,
The movement of the side cover is transmitted to the thermal head by the interlocking mechanism, and the thermal head is separated from the platen roller. After that, place the large-diameter recording paper roll on the side cover, attach the recording paper cover to the side cover, and move the recording paper cover to the position to cover the large-diameter recording paper. Printing is possible because the interlocking mechanism is driven to bring the thermal head closer to the platen roller to a printable distance.

In the second facsimile apparatus of the present invention, a large diameter recording paper roller is placed on the opened side cover, the leading end of the recording paper is manually loaded, and then the side cover is moved horizontally. Then, in conjunction with this, the thermal head approaches the platen roller and printing becomes possible.
