ていた。[Prior Art] Conventionally, roll-shaped recording paper is generally used as thermal paper in a thermal recording device (fax) or the like, and a band mark of a fixed width is printed on the back surface of the recording surface near the end of the recording paper. And
The end of the chart paper was displayed. In a thermal transfer recording device, a recording paper presence / absence detection sensor or the like provided inside the device detects the end of the recording paper that has come off the core, and the end information of the rolled recording paper is displayed on a display panel or the like outside the set. Was displayed.

た。The above prior art has the following disadvantages. Generally, a recording method in a thermal transfer type color hard copy device is as follows.
The recording paper is reciprocated, and each color (3-4
Color). For this reason, it is necessary to similarly rewind the roll-shaped recording paper in the vicinity of the end of the roll paper after recording the one color, which has a drawback that the end of the roll paper cannot be detected.
上記目的を達成するために、本発明はロール状記録紙
の終端部を巻芯に固着し、ロール状記録紙終端近傍に丸
穴を施したものである。In order to achieve the above object, in the present invention, the end portion of the roll-shaped recording paper is fixed to the core, and a round hole is formed near the end of the roll-shaped recording paper.

検出とはならない。The round hole at the end of the roll-shaped recording corresponds to the reflective sensor for recording paper detection installed in the thermal transfer type color hard copy device. Is zero or not, and there is a sensor output except for the round hole. The end signal of the roll paper can be detected by the presence / absence signal. Further, by fixing the end portion of the roll paper to the core, rewinding of the roll paper becomes possible, and reciprocal recording becomes possible. Also, especially when the roll-shaped recording paper is a transparent sheet, the gain of the reflective sensor is set high so that the sensor output of the transparent part can be output stably.
A method of attaching black recording or a black tape or the like to the vicinity of the end of the recording paper may be considered, but any of these methods generates reflected light and does not provide stable detection.

２−ｂが設けられている。There is a roll-shaped recording paper 2 wound around a core 1 by a predetermined amount.
The end portion 2-a of the roll-shaped recording paper 2 is fixed to the core 1 with an adhesive tape 3. A round hole 2-b is provided near the end.

表示をする。In FIG. 3, the normal thermal transfer recording apparatus sandwiches the roll-shaped recording paper 2 between paper feed drive rollers 4, 5 and paper feed driven rollers 6, 7, etc., advances in the direction of arrow A, and consumes the recording. At this time, the reflection type recording paper sensor 8 in the apparatus is connected to the light emitting side 8-
Infrared light is emitted from a, and the reflected light from the roll-shaped recording paper 2 is taken into the light receiving side 8-b to be used as a sensor output. This is a state in which the end of the roll-shaped recording paper 2 is not detected.
Next, when the roll-shaped recording paper 2 is consumed and the round hole 2-b comes directly below the recording paper sensor 8, the infrared rays from the light emitting side 8-a emit the infrared light from the round hole 2-b of the roll-shaped recording paper 2. b, the reflected light does not enter the light receiving side 8-b, and as a result, the sensor output becomes zero. This is the rolled recording paper 2 shown in FIG.
In the end detection state. Thereafter, the rolled recording paper 2 is rewound to a predetermined position by a recording paper rewinding mechanism in the apparatus (not shown), and an alarm such as running out of recording paper is displayed on a display plate or the like outside the apparatus.

ことが出来る。As described above, the present invention has a configuration in which a round hole is provided near the end of the roll-shaped recording paper and the round hole is detected by a reflection type infrared sensor. Even if the sensor setting has a high gain, since the sensor output is zero in the round hole, the end of the recording paper can be reliably detected. In addition, by fixing the end of the roll paper to the core, it is easy to rewind the recording paper during reciprocal repetitive recording such as thermal transfer color recording. You can do it.
