Abstract

PURPOSE:To reduce roundabout incidence of light on a light-receiving element and contrive to stabilize an ink donor film (IDF) trailing end detection output, by providing a light-emitting element and the light-receiving element so that their optical axes are parallel to each other. CONSTITUTION:At timings t1 and t2, although a surface (a) not provided with trailing end mark is located beneath a mark reading sensor 6, an output exceeding a reference voltage V0 of a comparator is detected due to specular reflection by the IDF 1 or the like. In the trailing end detecting circuit wherein the light- emitting element 40 and the light-receiving element 50 both of which are highly directional are so provided that their optical axes are parallel to each other, a detection output from the element 5 does not exceed the reference voltage V0 although it is increased at the timings t1 and t2. Accordingly, the level of an output e0 from the comparator becomes high only at timing t3 when a surface (b) provided with a trailing end mark is located beneath the sensor 6, so that the trailing end of the IDF 1 can be detected accurately and securely. In addition, the roundabout incidence of light on the element 50 due to specular reflection can be reduced by slanting the optical axes against the feeding direction of the IDF 1.

終端検知方式の−構成例を概念的に示したものである。As is well known, the transfer type thermal recording apparatus transports the recording section together with the recording paper while winding up the IDF from, for example, an IDF supply roller to a winding roller, and at this time, a predetermined portion of the line thermal head is transferred to the image information. A predetermined document is recorded by transferring the IDF ink, which is generated in response to heat generation and melted at the heat generating portion, onto the recording paper. For this reason, when the transfer thermal recording via the IDF progresses and all of the IDF is wound up by the take-up roller and there is no remaining amount on the supply roller, it becomes impossible to continue the transfer thermal recording. Conventionally, the following method has been used to detect the end of the IDF so that operations such as the above-mentioned recording failure can be dealt with quickly. Figure 1 shows the IDF in a conventional transfer type thermal recording device.
This figure conceptually shows a configuration example of the termination detection method.

Initially, the IDF 1 is wound around an IDF supply roller (not shown), is conveyed by the IDF supply roller which is rotationally driven at the start of recording, and is wound up by a take-up roller 3. When transporting the IDFI with
A termination mark reading sensor 6 consisting of a light emitting element 4 and a light receiving element 5 is arranged above F1.

いた。Based on this detection of the end of IDF1, an operation control section (not shown) in the apparatus executes control operations such as stopping the recording operation. In this way, in the conventional ink donor film end detection method, the surface state of the IDFI being conveyed is read by the end mark reading sensor 6, and the read value (photoelectric conversion output) is determined to be higher on the coated surface than on the end mark non-coated surface, for example. The end of the IDFI was detected by utilizing the increase in size. By the way, according to the conventional ink donor film end detection method, the light emitting element 4 and the light receiving element 5 constituting the IDF end mark reading sensor 6 are arranged as shown in FIG. The optical path of the reflected light from the IDFI of the light irradiated through the optical axis of the light incident on the light receiving element 5 coincided with the optical axis of the light receiving element 5.

できる。Further, FIG. 6 shows the case in which the IDFI is conveyed during recording and the position immediately below the IDF end mark reading sensor 6 shifts from the end mark non-formed surface to the end mark formed surface near the timing t3 in the figure. 2 is a timing chart of output waveforms of various parts of the termination detection circuit of the conventional method and the method of the present invention shown in the figure. First, when performing the above-described recording, the detection output of the light receiving element 5 of the conventional end detection circuit changes as shown in FIG. 6(a). According to the figure, even though the surface immediately below the IDF end mark reading sensor 6 is a surface on which no end mark is formed, the reference voltage of the comparator 7 is temporarily caused by specular reflection of the DF1 at timings t1 and t2. An output exceeding The output e of the comparator 7 of the conventional circuit to which the detection output of the light receiving element 5 is inputted as a comparison input.
. is the timing 11 and t as shown in Φ in the same figure.
2, the IDFI temporarily became 'H' level, and as a result, at the timings t1 and t2, it was falsely detected that the IDFI was at the end.However, the optical axes of the light emitting element 40 and the light receiving element 50 became parallel. In the termination detection circuit according to the present invention arranged as shown in FIG. 6(C), the detection output of the light receiving element 50 is as shown in FIG. Although the detection output number increases, it does not exceed the reference voltage ○ of the comparator 7. Therefore, the output eo of the comparator 7 of the circuit according to the present invention to which the detection output is input
4, the result is as shown in FIG. 4(d), and only at timing t3 when the surface immediately below the IDF reading sensor 6 becomes the end mark forming surface, the level becomes ``H'', and accurate and reliable IDF end detection can be performed. FIG. 7 is a schematic diagram showing the arrangement of an IDF end mark reading sensor according to another embodiment of the present invention. The IDFIs are arranged in such a manner that their optical axes are inclined with respect to the direction of conveyance of the IDFI. By arranging it in this manner, it is possible to further reduce the incident on the light receiving element 50 due to specular reflection than in the case of arranging it as shown in FIG. 4, and it is possible to achieve more accurate detection of the end of the IDF.
