Abstract

PURPOSE:To minimize the waste of a transfer film by controlling feeding of the transfer film in response to black level information of a binary picture data. CONSTITUTION:A reception motor 7 drives a feed roller 10 to feed recording paper 13. A transfer film feed clutch is provided to the reception motor 7 to apply transfer film feed clutch control with transfer film feed information from the motor control section to drive a transfer film feed roller 9 thereby feeding the transfer film 12. A thermal head 11 is in close contact onto the transfer film 12 to apply thermal transfer to the recording paper 13. when all one line has white level picture element data and all one line of white level picture elements are recorded, the recording paper is fed by line with the reception motor and the transfer film is controlled so as not to be fed in interlocking with the reception motor by releasing the transfer film feed clutch. Thus, waste of transfer film is minimized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine, and more particularly to a facsimile machine that employs a thermal transfer recording method in its reception recording section.

[Conventional technology]

FIG. 4 is a block elliptical diagram of an example of a conventional facsimile device.

In the decoding unit 14, the decoded binary image data is
It outputs to the printer section 18 through the recording control section 16. Further, synchronization during recording is executed by the motor control section 15 and the recording control section 16, and printing control is performed from the recording control section 16 to the printer section 18, and the motor control section 15
Therefore, a means has been used in which the receiving motor 17 is driven to simultaneously feed the recording paper and the transfer film by controlling the motor drive of the receiving motor 17.

[Problem to be solved by the invention]

In the conventional facsimile machine described above, since the recording paper and the transfer film are transported by the same amount by the receiving motor, documents such as documents and graphics with relatively little black information in the binary data can be handled. The disadvantage is that sometimes the transfer film is wasted.

[Means to solve the problem]

The Funakushimi device of the present invention includes means for detecting black information line by line from decoded binary image data, means for outputting a feed signal when the black information is detected, and a mechanism for conveying a mature transfer film. , a motor for driving this mechanism, and means for driving and controlling the motor using the feed signal.

〔Example〕

Next, the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram of one embodiment of the present invention.

The received data and the encoded data to be recorded are decoded into binary image data in a decoding section 1, and the binary image data is processed in a transfer film feed control section 2.
A transfer film feed signal is output to the motor control section 3. The motor control section 3 outputs feed pulses to the receiving motor 5 and simultaneously outputs transfer film feed information to the receiving mechanism system. Furthermore, the recording data is outputted from the transfer film field control section 2 to the recording control section 4 while taking into account line synchronization of motor feed, and the recording control section 4 synchronizes with the motor control section 3 and outputs it to the printer section 6. Then, perform printing pulse control.

FIG. 2 is a control timing chart of the transfer film feed control section 2 of this embodiment. It is assumed that signals are transferred from the decoding section 1 to the transfer film feed control section 2 in the form of a1 to a3. a1 is a 1-line data effective period, a2 is a data transfer clock, and a3 is binary image data, and a transfer film feed signal b is generated from these signals. In this embodiment, when there is black image data of l or more pixels in the n-th line, one pulse of the transfer film feed signal b is generated. The feed signal b is transferred to the transfer film feed control section 2.
When the binary image data of the n-th line is being transferred to the recording control section 4, it is output to the motor control section 3 in synchronization therewith.

FIG. 3 is a diagram showing the structure of the thermal transfer recording section of this embodiment.

The reception motor 7 drives the recording paper feed roller 10,
The recording paper 13 is fed. The reception motor 7 is provided with a transfer film feed clutch, and the transfer film feed clutch is controlled based on the transfer film feed information from the motor control unit 3, and the transfer film feed roller 9 is driven to feed the transfer film 12. . The thermal head 11 is connected to the transfer film 12,
The recording paper 13 is brought into close contact and thermal transfer is performed on the recording paper 13.

In the embodiment shown in FIGS. 2 and 3, if the document information to be recorded is all white pixel data in one line in an arbitrary line in the main scanning direction, the data of all white pixels in that one line is When recording, the recording paper is fed one line by the reception motor, but the transfer film is controlled so that the transfer film feed clutch is turned off and the transfer film is not fed in conjunction with the reception motor.

〔Effect of the invention〕

As explained above, in the present invention, the feeding of the transfer film is
By controlling according to the black information of the value image data, it is possible to minimize the waste of the transfer film and extend the life of replacing the transfer film.
