Description

TECHNICAL FIELD The present invention relates to a facsimile apparatus that uses roll paper as a recording medium.

(Prior Art) Generally, in a facsimile apparatus, a roll paper obtained by winding a thermosensitive recording paper in a roll shape is used, and at the time of reception, the roll paper is fed to a recording unit of the facsimile apparatus and the recording unit The received contents are printed by the thermal head while the roll paper is fed in a predetermined manner.

The roll paper is stored in the facsimile main body or in a cassette detachably attached to the facsimile main body.

(Problems to be solved by the invention) By the way, in the facsimile apparatus, the demand for the capacity (length) of the roll paper differs depending on the usage status of the roll paper by the user.

Therefore, for example, in order to accommodate a user who uses a lot of roll paper, in the structure in which the roll paper is stored in the facsimile main body as in the conventional case, the outer shape of the main body becomes large because it is necessary to secure a space for storing a large amount of roll paper. At the same time, even in the case of the cassette type structure, the entire external shape becomes large and the installation space of the facsimile main body becomes large when the cassette is used.

On the other hand, for users who rarely use roll paper, a small volume of roll paper is sufficient, and the storage space is small, so the external shape and installation space of the main unit can be reduced. Even if there is no problem in using a small amount of roll paper, if a large amount of roll paper is occasionally used or if roll paper is continuously used due to a long absence such as a business trip, the roll paper will be lost early and received. It may be impossible.

The present invention has been made in view of the above problems,
It is an object of the present invention to provide a facsimile apparatus that enables downsizing of a facsimile main body and securing of a roll paper capacity, and prevents early reception failure due to paper shortage.

(Means for Solving the Problems) A facsimile device of the present invention is a facsimile device that uses roll paper as a recording medium, and detects an internal roll paper that is housed inside a facsimile main body and is fed to a recording unit. A detection unit is provided, and when the detection unit detects that the internal roll paper has run out, a feed roller that switches and feeds the external roll paper externally attached to the outside of the facsimile main body to the recording unit inside the facsimile main body is provided. It is provided.

(Operation) In the facsimile apparatus of the present invention, roll paper is set inside and outside the facsimile main body, and when it is detected that the roll paper inside has run out, the roll paper outside is switched to the recording unit and continuously fed. It is available.
