Abstract

PURPOSE:To reduce the consumption of the battery of a main-body control section by housing the battery into an internal cylinder holder, on which roll paper is wound, and supplying a printing section with the power of the battery through the connection structure of a hemispherical electrode and a leaf spring electrode in a printer for a portable type device. CONSTITUTION:A plurality of batteries 3-5 are incorporated into a cylindrical holder 2, on which roll paper 1 is wound, and positive and negative hemispherical electrodes 6, 7 are arranged at both ends of the holder 2. When roll paper 1 is mounted at the specified position of a printer, each electrode 6, 7 is connected electrically to positive and negative leaf spring electrodes 8, 9 on the printer body side, and electricity is conducted through the printing section of the printer. The roll paper 1 is rotated as printing progresses in the printing section. Accordingly, when the printing section is supplied with power apart from the supply of a main-body control section with power, the consumption of the supply batteries for the main-body control section with printing operation can be reduced, thus largely extending an operating time at the time of non- printing operation.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to roll paper for printers,
In particular, it relates to roll paper for printers used in portable devices.

[0002]

2. Description of the Related Art In a conventional printer of a portable device, the power source of the printing section is shared with the main body control section.

[0003]

In the conventional printer of the portable device, the battery for the power source of the printing section is shared with the main body control section, so that a large amount of power is consumed during normal printing, so that the main body control section When the power supply battery performs the printing operation, it is consumed in a short time, and there is a drawback that the usage time in the non-printing operation is significantly shortened.

[0004]

The roll paper for a printer of the present invention comprises a battery in a cylindrical holder, a semi-spherical electrode for supplying power from the battery to the outside, and a leaf spring electrode.

[0005]

The present invention will be described below with reference to the drawings.

FIG. 1 is a side view showing an embodiment of the present invention. The roll paper 1 is wound around the cylindrical holder 2 and is appropriately drawn out to the printing portion during printing to perform printing. When the roll paper 1 is pulled out, the cylindrical holder 2 rotates an appropriate amount and supplies the roll paper 1 until the roll paper 1 is used up. Now, the electrons 3 to 5 are built in the inside of the cylindrical holder 2, and they are connected to the positive semi-spherical electrodes 6 and the negative semi-spherical electrodes 7 attached to the left and right of the cylindrical holder 2, and The positive semi-spherical electrode 6 contacts the positive leaf spring electrode 8 and supplies a positive power source 11, and the negative semi-spherical electrode 7 contacts the negative leaf spring electrode 9 and supplies a negative power source 10.

Each of the positive semi-spherical electrode 6 and the negative semi-spherical electrode 7 has a semi-spherical shape and makes a point contact with the positive leaf spring electrode 8 and the negative leaf spring electrode 9 to power the batteries 3 to 5 to the cylindrical holder 2. While simultaneously supplying it to the outside of the cylinder holder 2 and roll paper 1
It is possible to freely rotate, and thus it is possible to supply the positive power supply 11 and the negative power supply 10 at the same time as the roll paper 1 at the time of printing. The positive leaf spring electrode 8 is
The positive semi-spherical electrode 6 is pressed by the spring force toward the cylindrical holder 2, and the negative leaf spring electrode 9 also presses the negative semi-spherical electrode 7 toward the cylindrical holder 2 by the spring force. As a result, force is constantly applied so as to sandwich the cylindrical holder 2 from both directions, and contact failure is prevented.

[0008]

As described above, according to the present invention, the battery is built in the cylindrical holder of the roll paper used in the printer of the portable device, and the power is supplied to the printing portion by the semi-spherical electrode and the plate spring electrode. Therefore, even if the printing operation is performed, the battery consumption of the main body control unit can be reduced.
