Abstract

PURPOSE:To make an external farm of a device small by eliminating a battery pack holding space, by a method wherein a spool part supporting a rolled recording paper, which is tuned by being pulled by a platen roller part, and housing the battery pack which is provided. CONSTITUTION:A platen roller part. 1 is turned by driving force of a stepping motor and paper feed is performed. At this time, since an end part of a roll recording paper 3 is pulled by the platen roller part 1, a spool part 4 is fixed to a main body so that a position of the rolled holding paper 3 is not slipped off. Then the spool part 4 performs also holding of a battery pack 5 far driving of a device into which a printer unit is incorporated to the rolled recording paper 3 which has been sent away to the platen roller part 1 based on printing information. Since the battery pack 5 is held into a cylindrical space on the inside of a spool part 4 like this, it becomes unnecessary to provide the space, in which the battery pack is held, into the printer unit.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer unit, and more particularly to a printer unit having a roll recording sheet for recording print information, which is operated by a battery incorporated in an apparatus incorporating the printer unit.

[0002]

2. Description of the Related Art Conventionally, a roll recording paper for recording print information has been built in a printer unit of this type, but a driving battery is built in outside the printer unit though it is inside the device. It was

[0003]

As described above, in the past,
When a driving battery is incorporated in a device having a printer function, a space for accommodating the driving battery is separately provided and stored therein. For this reason, by using batteries, it is necessary to secure a space for accommodating the driving battery even in a device having a printer function that is free from the power supply from the AC power supply and has high mobility, and the size of the device itself. Has the disadvantage that it is enlarged and its mobility is impaired.

An object of the present invention is to solve the conventional drawbacks described above and to provide a printer unit in which a space for accommodating a driving battery can be secured by effectively using the internal space of the printer unit. It is in.

[0005]

A printer unit according to the present invention comprises a platen roller section for feeding a recording sheet to be printed, a recording section for recording print information, and a roll for recording the print information by the recording section. The recording paper includes a recording paper and a spool portion provided in a space within a roll diameter of the roll recording paper to support the roll recording paper which is pulled and rotated by the platen roller portion and accommodates a battery pack therein.

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

FIG. 1 is a perspective view of an embodiment of the present invention, and FIG. 2 is a perspective view of another embodiment of the present invention.

First, the components shown in FIG. 1 will be described.
The printer unit of this embodiment includes a platen roller unit 1 that transmits a driving force from a driving source to feed a sheet, a recording unit 2 that emits energy such as heat, and a roll recording paper that develops color by the energy emitted from the recording unit 2. 3 and a spool portion 4 having a function of accommodating a battery pack 5 for stabilizing the rotation of the roll recording paper 3 and driving the roll recording paper 3, and passing the spool portion 4 inside the roll diameter of the roll recording paper 3 and further The driving battery 5 is housed in the space. That is, in FIG.
The platen roller unit 1 transmits the driving force from the driving source to feed the paper. The recording unit 2 emits energy such as heat based on the print information. The roll recording paper 3 is colored by energy such as heat given from the recording unit 2. The spool unit 4 has the functions of stabilizing the rotation of the roll recording paper 3 and storing the driving battery pack 5, and is fixed to the apparatus main body.

Next, the operation will be described. The platen roller unit 1 is rotated by a driving force from a driving source such as a stepping motor to feed the paper. At this time, the spool portion 4 is fixed to the main body so that the position of the roll recording paper 3 does not shift because the end portion of the roll recording paper 3 is pulled by the platen roller portion 1. The spool unit 4 also stores a battery pack 5 for driving a device in which the printer unit is incorporated. The recording unit 2 performs printing by applying energy such as heat to the roll recording paper 3 sent by the platen roller unit 1 based on the print information.

In this way, the spool unit 4 is passed through the cylindrical space inside the roll recording paper 3 and the battery pack 5 is housed in the cylindrical space inside the roll recording paper 3, thus incorporating the printer unit. It is not necessary to provide a space for accommodating the battery pack 5 in the device, and the outer shape of the device can be reduced.

Next, the components of the printer unit of another embodiment shown in FIG. 2 will be described. In FIG. 2, the platen roller unit 11 transmits the driving force from the driving source to feed the paper. The recording unit 12 emits by energy such as heat based on the print information. The roll recording paper 13 develops color by energy such as heat given from the recording unit 12. The spool unit 14 has the functions of stabilizing the rotation of the roll recording paper 13, storing the driving battery pack 15, and transmitting the electric power of the battery pack 15 to the spool receiving unit 16, and is set so as to be in contact with the spool receiving unit 16. . The spool receiving portion 16 has a function of positioning the spool portion 14 and receiving electric power from the spool portion 14 to transmit power.

Next, the operation will be described. The platen roller unit 11 is rotated by a driving force from a driving source such as a stepping motor to feed the paper. At this time, the spool portion 14 is fixed by the spool receiving portion 16 so that the position of the roll recording paper 13 does not shift when the end portion of the roll recording paper 13 is pulled by the platen roller portion 11. The spool unit 14 also stores a battery pack 15 for driving a device in which the printer unit is incorporated, and sends electric power to the spool unit 14. The spool receiver 16 supplies the electric power sent from the spool 14 to a package or the like. The recording unit 12 prints by applying energy such as heat to the roll recording paper 13 sent from the platen roller unit 11 based on the print information.

In this manner, the spool unit 14 is passed through the cylindrical space inside the roll recording paper 13 and the battery pack 15 is housed in the cylindrical space inside the roll recording paper 13 to incorporate the printer unit. It is not necessary to provide a space for accommodating the battery pack 15 in the device, and the outer shape of the device can be reduced. Finally, the printer unit can be applied to word processors, facsimile machines, and the like.

[0014]

As described above, according to the present invention, it is necessary to provide a space for accommodating the battery pack in the apparatus incorporating the printer unit by accommodating the battery pack in the space within the winding diameter of the roll recording paper. This has the effect of reducing the size of the device.
