Abstract

PURPOSE:To enable a transfer ribbon to be effectively utilized, by rewinding a part of the transfer ribbon by a rewinding means before starting pressing by a printing head. CONSTITUTION:A transfer ribbon rewinding controlling part 8 is provided for rewinding the transfer ribbon by a predetermined amount after releasing the pressing of a thermal head. Where one or more spaces are present in printing in a line, the pressing of the thermal head is released, but even in the period of time required for completely releasing the pressing of the head 1, a transfer ribbon taking-up means 2 is rotated, whereby an unused part of the transfer ribbon 3 is taken up. When the pressing is completely released, the rewinding means 4 for the ribbon 3 is driven to rewind the ribbon 3 by a length equal to the sum of the length of the ribbon taken up by the taking-up means 2 during releasing the pressing and the length of the ribbon taken up by the means 2 in the period from the start of the pressing to the start of printing. Accordingly, since the ribbon part taken up in an unused state is rewound and used, effective utilization of the transfer ribbon can be contrived.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an improvement in a printing device, and to a printing device and a printing method therefor that are capable of effectively utilizing a transfer ribbon by installing a rewinding means for rewinding the printing method.

[Prior art]

Conventionally, in a thermal transfer printer that drives a transfer ribbon and presses a thermal head against a transfer ribbon to perform thermal transfer printing, if there is at least one blank character in one line of printing, the thermal head presses the blank character part. Can I cancel the transfer? In this method, the drive of the thermal head is stopped, and then the pressure contact of the thermal head is started at least one character before the printing start character. While the thermal head is being released from pressure contact, the transfer ribbon is not driven so that the transfer IJ gun can be used effectively. There was a drawback that the ink ribbon was wound up unused before printing started.

〔the purpose〕

Therefore, an object of the present invention is to provide a printing method to solve the above-mentioned object.

〔composition〕

In order to achieve the above object, the present invention provides a print head.

In a printing device equipped with a transfer ribbon and a winding means for winding the front end self-transfer ribbon, there is provided a rewinding means for rewinding the transfer ribbon; In the printing method in which the pressure contact of the print head 9 is released in the blank printing section and the print head is brought into pressure contact at least one character before the next printing start character, the rewinding means is provided before starting the pressure contact with the print head. The method is characterized in that a part of the transfer ribbon is rewound by .

〔Example〕

Embodiments of the present invention will be described in detail and specifically below with reference to the drawings. Fig. 1 is a schematic drawing of the carriage running system of a printing device such as a thermal transfer printer, and a diagram of the control unit. A5It) means for winding the transfer ribbon rotating at a speed synchronized with the speed;
3 is a transfer ribbon to which ink is transferred by a thermal spatula l'; 4 is a rewinding means for rewinding the transfer ribbon when the pressure contact of the thermal head is released; 5 is a carriage running system; and 6 is a transfer ribbon for transferring data to be recorded by the thermal head. Print control section to be created,
Reference numeral 7 refers to a head pressure contact control unit that controls pressure contact and release of the thermal head; 8 refers to a transfer ribbon rewind control unit that rewinds the transfer ribbon by a certain amount after release of the thermal head pressure contact; 9 refers to a transfer ribbon unwinding control unit of the present device; A control section 10 controls the carriage and feed motor, and 10 is a main control section that controls the control sections 6, 7, and 8.9.The winding means 2 records the carriage 1 that is in contact with the head I'fE. There is a means for winding up mechanically or a means for winding up using a motor as the carrizo moves in the direction.
A method for mechanically rewinding a certain amount when the carrier is moved in the recording direction with the head released from pressure contact, or
The motor has a means of rewinding it.

FIG. 2 is a flowchart showing a printing method for printing one line in this embodiment.The printing method of this embodiment will be explained below with reference to FIG. 1 and FIG. A judgment S1 is made as to whether or not there is a blank character in printing one line. If there is no blank character, printing processing S6 is carried out. Then, a judgment 87 is made as to whether or not one line is finished. If it is finished, the process goes to the next process (not shown). Then S
1, and repeat the above flow until a blank character is found. At this time, in the carriage running system 5, the thermal head 1 is already in pressure contact with the transfer gun 3 before step S1 in FIG. Printing is performed while rotating. At this time, the transfer ribbon rewinding means 4 is not loaded with respect to the transfer ribbon winding means 2.

Next, if there is a blank character in one line of printing, the process moves from step S1 to step S2 in FIG. 2, and the pressure contact of the thermal head is released (step S2). However, since the transfer ribbon winding means 2 continues to rotate until the thermal head 1 is completely released from pressure, the unused transfer IJ yl? The ribbon is wound. Next, when the pressure contact is completely released, the state shifts to Stella fs3. Transcribe here? The transfer ribbon is wound around the transfer ribbon winding means 2 between the start of pressure contact and the start of printing, which will be described later. The transfer ribbon is rewound by the length f of the removed transfer ribbon. When step S3 is completed, the process moves to Stella fs4, and when the thermal head pressure contact start point has arrived, the process moves to Stella:7'S5, and when the thermal head pressure contact start point has not arrived, the movement of the blade is continued. In step s5, the thermal head is pressed, and when the thermal head starts to be pressed, the transfer ribbon winding means 2 starts to drive and winds up the transfer ribbon from before the actual printing position. The amount of transfer ribbon to be wound up at this time has already been rewound by the stepper 3. Next, the process moves to Stella fS6 and printing is performed.

〔effect〕

As described above in detail and specifically, according to the present invention, the transfer ribbon that has been wound up unused can be rewound and used again, so that the transfer ribbon can be effectively utilized.
