Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an energized heat-generating recording device that performs printing using heat-melting ink.

<Prior art> Conventionally, as devices that perform recording by thermal transfer, there are two types: (1) a thermal transfer recording device that heats a thermal transfer film using a thermal head and prints by transfer; (2) a thermal transfer recording device that uses a thermal head to heat a thermal transfer film and prints by transfer; 2. Description of the Related Art Electric transfer recording devices and the like that perform printing by transfer are known.

However, in the thermal transfer recording device mentioned above, the thermal head is expensive and the recording speed is slow (approximately IKpps).
The disadvantage is that the recording paper is limited to thermal recording paper and it is not possible to record on plain paper, and the above-mentioned electric transfer recording device (2) has the disadvantage that it is expensive because the electric transfer film has a multilayer structure including an electric layer. Ta.

<Purpose> The present invention has been made in order to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a new energizing heat-generating recording device which can be constructed at a relatively low cost and is capable of high-speed recording on plain paper. That purpose.

<Example> Hereinafter, an example of the energization heat generation recording device according to the present invention will be described in detail with reference to the drawings.

I is an endless ribbon-shaped electrified heating film,
The electrical heating film 1 has a resistance layer made of carbon black and synthetic resin on its inner surface, and a conductive layer made of an aluminum vapor-deposited film on its outer surface. A plurality of recording electrode needles 3 protruding from the current-carrying head 2 are in contact with the surface of the resistance layer on the inner side of the energizing heat-generating film 1, and a return electrode 4 is in contact with the other portion of the surface of the resistance layer. The above energizing heat generating film l
A recording paper 8 is disposed on the outer surface of the recording paper 8, and a heat-sensitive transfer film 5 is disposed between the energizing heat generating film l and the recording paper 8. The heat-sensitive transfer film 5 is composed of a base material and a heat-melting solid ink layer, and the heat-melting solid ink layer is placed on the side of the recording paper 8, and the recording electrode needle 3 transfers current through the heat-generating film l and the heat-sensitive transfer film 1 by the printing pressure. Thermal transfer film5. Press against recording paper 8. Incidentally, the above-mentioned energized heating film 1 can be sent endlessly and can be used repeatedly. A recording current is sent from the drive circuit 9 to the three selected electrode needles, and the electrode needles 3 cause the energized heat generating film 1 to
The resistance layer near the electrode needle 3 is heated. The current flowing through this resistance layer flows through the return electrode 4, which is a conductive layer on the outer surface of the energizing heat generating film l.

The electrode needle 3 generates heat in the energized heat generating film 1, and due to this heat generation, the ink layer of the thermal transfer film 5 is transferred to the recording paper 8.
The image is then thermally transferred and recorded. As this recording progresses, the recording paper 8 is fed in the direction of arrow A, and the thermal transfer film 5 and energized heat generating film l that are in pressure contact are also sequentially fed in conjunction with this, thereby updating the recording surface. . Here, unused thermal transfer films 5 are sequentially supplied from a supply reel 6, and the thermal transfer film 5 after being used for recording is wound up by a winding reel 7.

The recording device with the above configuration is a serial printer.

It can be applied to any line printer.

<Effects> According to the present invention, since the recording head is composed of electrode needles, the manufacturing cost is much lower than that of conventional thermal heads, and heat generation is generated by the energized heat generating film. It is more resistant to thermal stress than conventional thermal heads, and since the heat generating position of the energized heat generating film is updated sequentially, there is less influence of heat accumulation, achieving a high recording speed (approximately 5Kpps ~ OKpps). It is possible.

In addition, it is possible to record on plain paper, and the only consumable item required is an inexpensive heat-sensitive transfer film, so running costs are low.
