Abstract

PURPOSE:To make the size of a device smaller to enhance the portability thereof in a printer using machine glazed paper by putting a control circuit and battery in a core of the machine glazed paper. CONSTITUTION:In a facsimile wherein machine glazed paper is used, a contol circuit unit 2 and battery pack 3 are placed within a core of machine glazed paper 1. And the unit 2 is connected to a motor, printing head 4, image sensor 5 etc., of a main body by means of connectors, contacts, photocouplers etc. At the time of printing, the paper 1 is fed by a feed roller 6 to perform printing by means of a printer head 4. And for use as FAX, a copy 7 sent by the feed roller 6 is read by an image sensor 5 to transmit it to the outside by means of a communication device. And reception is performed by the communication device, wherein the paper 1 is printed by means of the printer head 4 so as to be outputted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer, and more particularly to a printer having a facsimile function using roll paper.

[0002]

2. Description of the Related Art In a conventional FAX, as shown in FIG. 3, a roll paper 101, a control circuit unit 102, and a battery pack 103 are arranged at independent positions. For the transmission of the original, the original 105 sent by the document feed roller 104 is read by the image sensor 106, and the original is sent outside by the communication unit in the control circuit unit 102. When receiving, the image received by the communication unit is printed by the print head 108 on the roll paper 101 sent by the sheet feed roller 107.

[0003]

However, in the conventional printer and FAX, the internal space of the roll paper core becomes a dead space and there is a limit to miniaturization.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a printer which can effectively reduce the size of the roll paper by effectively utilizing the inner space of the core of the roll paper.

[0005]

Therefore, in order to achieve the above-mentioned object, the present invention has a structure in which the control circuit or the control circuit and the battery pack can be housed inside the core of the roll paper.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of the present invention will be described with reference to FIGS.
Will be described with reference to.

In the present invention, as shown in FIGS. 1 and 2, the control circuit unit 2 and the battery pack 3 are provided inside the core of the roll paper 1.
The control circuit unit 2 is connected to the motor of the main body, the print head 4, the image sensor 5, and the like by a connector, a contact, a photocoupler, or the like. During printing, the roll paper 1 is conveyed by the feed roller 6 and the print head 4
Is printed by. The motor that drives the printing and feed roller 6 is controlled by the control circuit unit 2, and the power is supplied from the battery pack 3. When used as a FAX, the original 7 sent by the feed roller 6 is read by the image sensor 5 and is sent to the outside by the communication device in the main body or a separate unit. Further, reception is performed by the communication device, and when printing is performed, printing is performed by the printer head 4 as described above. When used as a copying machine, the image of the original 7 read by the image sensor 5 is printed by the print head 4 to perform copying. All of these operations are performed by the control circuit unit 2.

In any case, the control circuit unit 2
Also, the battery pack 3 is detachable from the main body, but it may have a structure in which only the roll paper 1 can be detachable from the main body.

[0009]

As described above, according to the present invention, the control circuit or the control circuit and the battery pack are stored inside the core of the roll paper which has become a dead space, so that the apparatus can be downsized and the portability is improved. improves.
