Abstract

PURPOSE:To contrive the preservation of confidential information, by providing a correction head for correcting by transferring the patterns left on a thermal transfer material such as a ribbon and a sheet. CONSTITUTION:Information from a recording-controlling part 3 is inputted into a transfer head controlling part 4, where it is converted, and the converted information is outputted to a transfer head 5. Simultaneously, the controlling part 4 outputs a timing signal for writing to a delay circuit 6. The delay circuit 6 delays the timing signal by a period of time required for a reverse pattern formed on the ribbon 1 to move to the position of the correction head 7. The delayed timing signal is outputted from the circuit 6 to a correction head controlling part 8, which outputs a solid transfer signal to the deleting head 7, whereby the pattern on the ribbon 1 is made to be blank, resulting in that the information on the ribbon 1 is deleted. Accordingly, the situation in which recording information is needlessly left on the ribbon or the like can be prevented, and confidential information can be preserved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a recording device, and particularly to a thermal transfer recording device using a thermal transfer ribbon or sheet.

[Prior art]

FIG. 1 schematically shows the state of the paper and the state of the recording paper after transfer by a conventional thermal transfer recording apparatus. As is clear from the figure, the recording pattern (A in this case) is transferred from the tape 1 onto the recording paper 2. Therefore, an inverted pattern of the recording pattern is left in the pattern 1. Therefore, the content recorded on the recording paper 2 remains on the ribbon 1, and the information can be read from the ribbon 1.

As described above, the conventional thermal transfer recording apparatus has the disadvantage that the confidentiality of information cannot be maintained.

[Purpose of the invention]

The present invention was made in view of the above-mentioned drawbacks of the conventional technology.6J)
The purpose is to provide a thermal transfer recording device that maintains the confidentiality of information by erasing the nine-four turns left on the thermal transfer material.

[Summary of the invention]

In order to achieve the above object, the thermal transfer recording apparatus according to the present invention is characterized by being equipped with an erasing head that erases by transferring the AI pattern left on a thermal transfer material such as a cartridge or a sheet.

[Embodiments of the invention]

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a block diagram showing the structure of a first embodiment of a thermal transfer recording apparatus according to the present invention.

In the figure, information output from a recording control section 3 is input to a transfer head control section 4, where it is converted into a signal for the transfer head 5 and output to the transfer head 5. At the same time, the transfer head control unit 4 outputs a timing signal to the delay circuit 6 indicating that holding has been performed.

The delay circuit 6 delays the timing signal by the amount of time that the inverted pattern (see FIG. 3(a)) formed on the pattern 1 by driving the transfer head 5 moves at the position tt of the erasing head 7. . When the delayed timing signal is output from the delay circuit 6 to the erase controller 8, the erase head controller 8 outputs a full-surface transfer signal to the erase head 7, as shown in FIG. 3(b). , leave the pattern on body 1 blank. In this way, the information on the recan 1 is erased.

FIG. 4 is a block diagram showing the configuration of a second embodiment of the present invention. In this embodiment, the delay in the first embodiment is changed to 6.
An inverting circuit 9 is provided between the erase head control section 8 and the erase head control section 8, but otherwise the configuration is substantially the same as that of the first embodiment.

The operation of this embodiment will be explained. First, information output from the recording control section 3 passes through the transfer head control section 4 to the transfer head 5.
and is also output to the delay circuit 6. The signal is output from the transfer head control section 4 and is output to the inversion circuit 9 with a time delay.

Since the signal input to the inversion circuit 9 is the same as the information recorded by the transfer head 5, it can be expressed as shown in FIG. 5(a). When this signal is input to the inverting circuit 9, it is output as an inverted pattern signal as shown in FIG. 5(b). This inverted pattern signal is input to the erasing door by the erasing head controller 8.

Therefore, is it formed by the transfer head 5? N1
No J above? For the turn [Fig. 3(a)], the door is erased as shown in Fig. 5(6) in order to perform the transfer by the inverted Noreen shown in Fig. 5(b). The turn becomes blank and the mother turn is erased.

In this example, since the number of transfer areas is small,
Compared to the first embodiment, the consumption and power consumption of the erasing head 7 can be reduced.

Although the first and second embodiments have been explained using five thermal transfer materials, it is clear that the present invention is also applicable to sheet-type thermal transfer materials.

〔Effect of the invention〕

As explained in detail above, the thermal transfer recording device according to the present invention has the effect of preventing recorded information from being unnecessarily left on a ribbon or the like and ensuring the confidentiality of information.
