[Prior art]

 In a conventional thermal transfer recording apparatus used for a facsimile, a printer, etc., a heating element capable of generating heat in accordance with recording image information heats an ink ribbon that is in close contact with the recording medium to fuse the ink onto the recording medium and peel it. The mechanism separates the two, and at the same time, the cutter fixed blade that cuts the recording medium to which the recorded image has been transferred to a required length is cut by the rotating cutter blade that rotates (hereinafter referred to as the cutting forward path). After the cutting operation, the cutter rotary blade returns to the origin to prepare for the next cutting operation (hereinafter referred to as the cutting return path).

The recording medium to be cut is held at the same position on the paper feeding / conveying system in both the cutting forward path and the cutting backward path in which the cutter rotary blade rotates.

[0004]

[Problems to be solved by the device]

 However, in the conventional thermal transfer recording apparatus, when the cutting forward path for cutting the recording medium and the cutting return path for returning the cutter rotary blade toward the origin are performed, the recording medium is held at the same position on the paper feeding and conveying system. Therefore, the same end face of the recording medium is cut twice by the cutter rotary blade, and the end face of the recording medium output from the device is cut twice and is aesthetically deteriorated. There has been a problem that an extra-fine strip, which occurs when the paper is cut twice in the cutter mechanism, hinders the feeding of the recording medium in the paper feeding and conveying system.

The present invention has been made to solve the above problems, and an object of the present invention is to control the returning operation of a cutter rotary blade and the rotation direction and speed of a motor for conveying a recording medium. Another object of the present invention is to provide a recording apparatus which prevents the end face of the recording medium from being cut twice.

The above and other objects and novel features of the present invention will be made clear by the description of the present specification and the accompanying drawings.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the recording medium according to the present invention comprises means for controlling the rotation direction and speed of a motor for conveying the recording medium after the recording operation on the recording medium is completed. It is characterized by preventing double cutting.

[0008]

[Action]

 According to the above-mentioned means, the motor that conveys the recording medium after the recording medium is cut is rotated in the reverse direction so that the end face of the recording medium is moved away from the cutting mechanism section including the cutter fixed blade and the cutter rotary blade. Prevents double-cutting, and provides a recording medium output with an excellent aesthetic appearance.

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In all the figures, those having the same function are designated by the same reference numeral, and repeated description thereof will be omitted. FIG. 1 is a schematic configuration diagram showing the configuration of the entire recording apparatus including a cutting mechanism unit according to an embodiment of the present invention, and FIG. 2 is a diagram showing the configuration of the cutting mechanism unit in this embodiment.

In the recording apparatus of this embodiment, as shown in FIG. 1, the recording medium 10 wound on a roll and the thermal transfer ink ribbon 9 wound on the roll are heated according to the recording image information. It is pulled out to the position of the recording head 11 and the platen roll 12 having a heat generating element, and after the recording head 11 is pressed against the platen roll 12, the heat generating element of the recording head 11 is caused to generate heat, and the thermal transfer ink ribbon 9 The ink is melted and transferred to the recording medium 10.

In order to perform color thermal transfer recording of yellow, magenta, and cyan, the recording head 11 is raised after printing yellow, the recording medium 10 is returned to its original position by the platen roll 12 and a peel mechanism (not shown), Print cyan on. In this way, image information is formed on the surface of the recording medium 10, and after thermal transfer, the thermal transfer ink ribbon 9 and the recording medium 10 are separated by a peeling mechanism (not shown), and one of the separated thermal transfer ink ribbons 9 is wound. The recording medium 10 is taken up by the take-up roll 15, and the other recording medium 10 is sent by the paper feed roller 13 between the cutter rotary blade 2 and the cutter fixed blade 1 to the discharge roller 14, and is recognized by a paper edge sensor (not shown) and stopped. To do.

In this state, the drive motor 8 shown in FIG. 2 is driven to transmit the power to the wire pulley 6 interlocking with the movement of the gear through the gear train 7, and further between the wire pulley 6 and the wire pulley 5. The driving force of the motor is transmitted to the wire pulley 5 by the wire 4 which is looped.

At this time, the cutter rotary blade holder 3 configured to interlock with the movement of the wire 4 moves, and the cutter rotary blade 2 supported so as to rotate in the holder is fixed to the main body of the cutter. The cutter fixed blade 1 and the cutting edge are rotationally moved so as to slide on each other, the recording medium 10 is cut, and after cutting, the cutter rotating blade 2 is returned to the origin in order to prepare for the next copy.

Further, the conveyance of the recording medium 10 shown in FIG. 1 is performed by driving the platen 12 and the paper feed roller 13 by a paper feed motor (not shown), but as shown in FIG. 3, the paper feed motor 18 is It is connected to a central processing unit (hereinafter referred to as CPU) 16 via a driver 17, and is configured to be able to change in a predetermined speed and a rotation direction according to a set time by a timer provided in the CPU 16. .

Next, a control operation at the time of recording by the recording apparatus having the above-described configuration will be described with reference to FIGS. 4 to 6. A series of operations until the thermal transfer for one sheet is completed is performed in the same manner as in the conventional technique, and the time point when the recording for one sheet is completed is shown as step 19 in FIG. Next, in step 20, the paper feed speed, that is, the step speed for driving (normal rotation) of the motor is set to a predetermined value (NPPS) (for example, the recording medium 10 is thereby set at a speed of 12 mm / which is suitable for thermal transfer). s). Next, at step 21, the timer is set for P seconds, then at step 22, the paper feed motor 18 rotates forward for P seconds, and the recording medium 10 is conveyed at a speed of 12 mm / s. Whether or not P seconds have elapsed is determined by the step 23. If P seconds has not elapsed, the process returns to step 22 and motor drive continues, and if it has elapsed, the process proceeds to step 24 and the paper feed motor 18 is operated. Driving stops.

At this time, the leading end of the recording medium 10 is always conveyed to the direction of arrow A of the discharge roller 14 shown in FIG. 5, and the recording medium 10 is gripped by the paper feed roller 13 and the discharge roller 14. Is in a state. Next, in step 25, the recording medium 10 is cut (cutting forward path) while the cutter rotary blade 2 is rotationally moved on the cutter fixed blade 1. Subsequently, the operation for returning the origin of the cutter rotary blade 2 (return path for cutting) is performed in the same manner as the procedure of steps 20 to 24. At step 26, the step speed for driving (reverse rotation) of the motor It is set to a desired value (MPPS) (this allows the recording medium 10 to be conveyed at a speed of 3 mm / s suitable for paper return).

Next, in step 27, the timer is set for Q seconds, the process proceeds to step 28, the paper feed motor 18 rotates in the reverse direction for Q seconds, and the recording medium 10 is conveyed at a speed of 3 mm / s. Whether or not Q seconds have elapsed is determined in step 29. If Q seconds have not elapsed, the process returns to step 28 to continue motor drive, and if elapsed, moves to step 30 to drive the paper feed motor 18. Stop.

In order to prevent the cutter rotary blade 2 from coming into contact with the recording medium 10 during the backward movement of the cutter rotary blade 2, the amount of paper rewinding of the recording medium 10 at this time is the same as the cutter fixed blade 1 in FIG. When the distance from the position where the cutter rotary blade 2 slides to the center of rotation of the paper feed roller 13 is L, the distance l (lowercase letter L) for reversing the motor 18 and retracting the recording medium 10 is l = 1 / 3L. Step 27 is set to such a time that the sheet is conveyed in a direction away from the cutting mechanism so that it becomes ½ L.

Next, in step 31, while the cutter rotary blade 2 is again rotationally moved on the cutter fixed blade 1, the origin return operation (cutting return path) is performed, and the cutting mechanism unit performs the cutting operation of the next recording medium 10. When the state becomes possible, the process moves to step 32 and the next recording standby state is set.
