Abstract

PURPOSE:To allow a larger area of ink deletion than the area covered by data in a used transfer film and thereby conceal printed details more adequately by supplying print data provided to the first thermal element to the second thermal element through a delay mechanism so that the feed of print data is delayed by movement time. CONSTITUTION:Print data is supplied to the first thermal element 7 from a control part 9 through a print data signal line 10, and a position designated by print data in the first thermal element 7 becomes heated to print a designated set of data on a recording sheet 3. The residual ink of a transfer film 2 transfers the same print data to a deletion sheet 4 delayed by a print data delay mechanism 12 using the second thermal element 8 with a lower recording density than that of the first thermal element 7, if the transfer film 2 moves the arrive at the second thermal element 8. Subsequently, the ink around that transferred to the recording sheet 3 is transferred to the deletion sheet 4, so that ink is deleted over a larger area than that of the data recorded on the recording sheet 3.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer device, and more particularly to a thermal transfer type printer device using a transfer film.

0002

2. Description of the Related Art In a conventional printer device of this kind, a transfer film moved by a transfer film moving mechanism and a recording paper are arranged so that the transfer film moves in contact with the recording paper, and the transfer film and the recording paper are arranged so that the transfer film moves in contact with the recording paper. By arranging a heating element that generates heat at a position according to the supplied printing data at the position in contact with the printing data, and supplying the printing data to the heating element and the transfer film movement control signal to the transfer film movement mechanism, the printing data can be transferred to the printing data. Printing was performed by transferring the corresponding ink from a transfer film to recording paper.

[Problems to be Solved by the Invention] In the conventional printer device of this type described above, after printing, the printed content is of course recorded on the recording paper, but at the same time, the printed content is also recorded on the transfer film in the form of ink leakage. Since the printed content is readable from the transfer film, the content can be read from the used transfer film, and the recorded content has a disadvantage of poor confidentiality.

0004

[Means for Solving the Problems] A printer device of the present invention comprises: a transfer film moved by a transfer film moving mechanism; a recording sheet that moves in contact with the transfer film at a first position; an erasing sheet that moves in contact with the transfer film at a second position after passing through the transfer film, and a first heating element that is provided at the first position and generates heat in accordance with supplied data to transfer and record on the recording sheet. a second heating element which is provided at the second position and generates heat in accordance with the supplied data to transfer the data onto the erasing paper and has a lower recording density than the first heating element; and the transfer film is connected to the first heating element. and a delay mechanism for delaying the time required to move from the position to the second position, and delaying the print data supplied to the first heating element by the time through the delay mechanism. The heating element is configured to be supplied to the second heating element.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, and FIGS. 2 and 3 are plan views showing an example of a state in which ink is removed from a transfer film in this embodiment.

As shown in FIG. 1, the transfer film 2 is arranged so as to be in contact with the recording paper 3 and the erasing paper 4, and is driven by the transfer film moving mechanism 1 in the direction from the recording paper contact position to the erasure paper contact position. Move to. Recording paper 3
is driven by the recording paper moving mechanism 6, and the erasing paper 4 is driven by the erasing paper moving mechanism 5, and each moves in the same direction as viewed from the contact position with the transfer film 2. A first heating element 7 is placed at the contact position between the transfer film 2 and the recording paper 3, and a second heating element 8 is placed at the contact position between the transfer film 2 and the erasing paper 4, and heat is generated by signals supplied to each. death,
Transfer the ink from the transfer film 2 to the recording paper 3 and erasing paper 4.
Transfer to. A transfer film movement signal is supplied from the control unit 9 to the transfer film movement mechanism 1, the recording paper movement mechanism 6, and the erasing paper movement mechanism 5 via the transfer film movement control signal line 11. , recording paper 3, and erasing paper 4 are driven and moved.

Print data is supplied from the control unit 9 to the first heating element 7 via the print data signal line 10, and the position specified by the printing data of the first heating element 7 generates heat, and the recording paper is heated. Print the data specified in 3. A second heating element 8 whose recording density is coarser than that of the first heating element (for example, 64 times coarser)
The print data from the control unit 9 is transferred to the print data delay mechanism 1.
2. The print data delay mechanism 12 delays input data by the time required for the transfer film 2 to move from the first heating element 7 to the second heating element 8 and outputs the input data. Second
The position designated by the print data delayed by the print data delay mechanism 12 of the heating element 8 generates heat, and the designated data is printed on the erasure paper 4. The control unit 9 outputs print data and a transfer film movement control signal while print data exists.

In such an operation of this embodiment, print data is recorded by transferring the ink of the transfer film 2 onto the recording paper 3 by the first heating element 7, and at this time, the print data is not transferred and is recorded on the transfer film 2. When the transfer film 2 moves and reaches the position of the second heating element 8, the remaining ink is removed by the print data delay mechanism by the second heating element 8, which has a rougher recording density than the first heating element 7. The same data delayed by 12 is transferred onto erasing paper 4.

FIG. 2 shows an example of the state of ink loss on the transfer film 2 after passing through the first heating element 7, and the state of the transfer film 2 after passing through the second heating element 8 from the state shown in FIG. FIG. 3 shows an example of the state where the orgasm is over. Figures 2 and 3
As shown in the example, on the transfer film 2 that has passed through the second heating element 8, the ink around the ink transferred to the recording paper 3 is transferred to the erasing paper 4, and as a result, the data recorded on the recording paper 3 is Larger ink leakage occurs.

[0011]

Effects of the Invention As explained above, in the printer device to which the present invention is applied, ink bleeds larger than the recorded data on the used transfer film, leaving no trace of detailed printed recording content. This has the effect of improving the confidentiality of printed content.
