Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a copying machine,
A thermal transfer type recording device that is used for printers, facsimile machines, or multifunction devices of these types to obtain a recorded image by thermally transferring the ink of an ink ribbon to a recording medium, and particularly to perform cueing when resetting the ink ribbon. The present invention relates to a recording device capable of performing the following.

[0002]

2. Description of the Related Art For example, in a printer of a thermal transfer system, an ink ribbon is used, and the ink applied to the ink ribbon is heated by a print head section which is energized to transfer the ink to recording paper. The following one-time ribbon type and multi-ribbon type are known as ink ribbons used for this.

[0003] In the one-time ribbon system, at least three color inks of yellow (Y), magenta (M) and cyan (C) are repeatedly applied. It has at least three times the length of the stamp screen.

On the other hand, in the multi-ribbon system, as in the one-time system, at least three color inks of yellow, magenta and cyan are repeatedly applied. However, the transport speed of the ink ribbon is limited to the recording paper speed. Since the transport is performed very slowly at 1 / n times the transport speed (for example, n = 15), the length of one screen can be very short.

By the way, in the case of such an ink ribbon, for example, when a trouble such as a misfeed occurs, or when an inspection is performed, an operation of removing the ink ribbon from the printer and rewinding the ink ribbon may be performed. .

[0006]

When the ink ribbon is rewound and set in this manner,
It is preferable that the ink ribbon be used again from the boundary between the used portion and the unused portion.

Conventionally, however, there is no special means for detecting the boundary portion, so that it is necessary for the user to visually confirm the boundary portion. In particular, in the multi-ribbon system, since the boundary portion is difficult to understand, troubles such as erroneously winding up to an unused portion were not rare.

As described above, if the unused portion is wound up, there is a problem that the unused portion is discarded without being used as it is, which is uneconomical and has a problem in terms of effective use of resources. .

In view of the above-mentioned circumstances, an object of the present invention is to make it possible to reliably detect the head of an unused portion.

A second object of the present invention is to enable automatic cueing.

It is an object of the present invention to reliably detect the leading portion of an unused portion even if the leading portion of the unused portion is easily overlooked.

The cam 68 has a shape as shown in FIG. 5, and the rotation angle and the displacement have a correlation as shown in FIG.

The discharge section 7 has a pair of rollers,
The recorded card P is ejected to the outside.

The ink consumption presence / absence detecting means 8 detects the boundary between the last part of the used ink area and the first part of the unused ink area and automatically finds the boundary part. Check whether ink is consumed on the ribbon 1
The boundary is detected from the difference in light transmittance at 0. The ink consumption presence / absence detecting means 8 includes a first sensor 81, a second sensor 82, and a control unit 83 which receives signals α and β from these sensors and detects a boundary portion.
And The control unit 83 in this example is also used as the control unit 40 (see FIG. 2) that controls the operation of the power transmission mechanisms 45 and 46.

That is, as shown in the table of FIG. 8, the ink consumption detection means 8 uses light of various wavelengths (hereinafter referred to as inspection light) after using ink of each color applied to the ribbon 10. In this case, since the transmittance of the ribbon 10 differs depending on the wavelength of the inspection light (550 nm and 800 nm in this example), the boundary portion can be determined by using this.

For example, if an inspection light of 800 nm is used,
When examining the transmittance of the used portion of each of the cyan, magenta, and yellow colors that constitute one screen color, it is found that only the used cyan portion protrudes and has a good transmittance. I understand. From now on, when the inspection light of 800 nm is irradiated on the ribbon 10, when the used cyan application area is irradiated, the transmitted light is detected on the back side, so that the application position of cyan, that is, the use of ink The final position of the completed portion or the earliest position of the ink unused portion (that is, the cueing position) can be detected.

Therefore, in this example, as shown in FIG.
The first sensor 81 is installed along with the peripheral portion avoiding the central portion where ink is consumed, and is used as a reference sensor. The second sensor 82 is used as the ribbon 1 which consumes ink.
0 is installed in the center. That is, these first and second
The sensors 81 and 82 include a light projecting unit (not shown) that emits inspection light having a wavelength of 800 nm, and a light receiving unit (not shown) that outputs detection signals α and β when receiving the inspection light. .

According to the ink consumption presence / absence detecting means 8 having such a configuration, the transmittance is significantly higher in the area where the ink is used than in the unused area. Therefore, as shown in FIG.
From the detection signals α and β output from the light receiving section to the control section 40 in accordance with the light intensity of the transmitted light, the control section 40 detects a portion where the transmittance is sharply reduced, and detects this portion of the unused portion of the ink. It is configured to be able to detect as. The first and second sensors may be installed at a position downstream of the print head unit 5 in the feeding direction of the ribbon 10.
Since the ink of each color has already been consumed, it is preferable to provide the ink upstream of the print head unit 5.

The ribbon attachment / detachment detecting means 9 detects when the ribbon cassette 12 is attached to and detached from the recording apparatus main body. In the ribbon transport section 4 described with reference to FIG. 2, the driving gear 45A and the driven gear 45B The pin 9A provided on the intermediate gear 45F shown in FIG.
As shown in the figure, the detection lever 9C is provided with a projection 9B that engages with the pin 9A and slides in the vertical direction, and a detection sensor 9D that can contact the lower end of the detection lever 9C.

The detection lever 9C has a substantially R-shaped projection 9E formed at the upper end thereof. When the ribbon cassette 12 is mounted at a predetermined position, the projection 9E contacts the ribbon cassette 12. The detection lever 9C abuts and maintains its position without falling downward. On the other hand, when the ribbon cassette 12 is pulled out, no frictional force is generated between the ribbon cassette 12 and the projection 9E, and the ribbon cassette 12 falls down by its own weight and the lower end turns on the detection sensor 9D. The controller 40 connected to the output of the detection sensor 9D detects that the ribbon cassette 12 has been removed.

In the control section 40, once the ribbon cassette 12 is detached or attached due to replacement of the ribbon cassette 12 or unexpected misfeed, etc., the fact that the ribbon cassette 12 has been attached and detached is electrically stored.

Then, when the ribbon cassette 12 is mounted, the control unit 40 controls the feeding motor 43 and the winding motor 44 shown in FIG. Is output. This control unit 4
0 is the output signal α from the first sensor 81 and the second sensor 82 of the ink consumption presence / absence detecting means 8,
The signal is output until the cueing position of the ribbon 10 due to β is detected. When the cueing position is detected, the reverse rotation operation of the ribbon 10 is immediately stopped.

Further, a second control signal is output from the control unit 40, the normal operation of the feeding motor 43 and the winding motor 44 is started, and the first sensor 81 and the second sensor 8 are operated.
When the output values of the signals α and β from 2 become the same,
The output of the second control signal is stopped. Thereby, the ribbon 1
The zeroing operation is terminated.

When the detecting lever 9C is pushed up again by the rotating intermediate gear 45F with the start of the reverse rotation operation of the ribbon 10, and the detecting sensor 9D is turned off.
By this pushing-up operation, the protrusion 9E comes into contact with and slides on the ribbon cassette 12 again, and the position is maintained by the frictional force between the protrusion 9E and the ribbon cassette 12 until the ribbon cassette 12 is pulled out. It has become.
In addition, the pulling-out operation of the ribbon cassette 12 is analogous to the fact that the detection lever 9C is lowered to the position where it is locked to the detection sensor 9D. It has become.

Next, the operation of actually recording information on the card P using this recording device will be described. When a print command is input to the control unit 40, the supply roller 21 is rotated in the card sending direction by a drive motor (not shown) (clockwise in FIG. 1), and the uppermost card P is transferred from the mounting table 11 to the separation rollers 22 and 23. Will be sent out. The sent card P is separated from the next card P by separation rollers 22 and 23, and sent to the registration roller pair 31.

The position of the leading edge of the card P sent to the pair of registration rollers 31 is confirmed by the position detection sensor 35. Here, the controller 40 controls the transport operation of the card P, the heating operation of each head, the transport operation of the ribbon, the upward movement operation of the platen roller, and the like based on this position.

The card P is transported toward the print head unit 5 by a transport belt 34 stretched between the driven roller 33 and the drive roller 32. For example, in a yellow station (not shown), when a predetermined number of pulses are counted from the position detection sensor 35, the control unit 40 adjusts the timing of the leading end of the card P to pass through the yellow head 51Y, and The step motor 69 is operated to push up the platen roller 61Y immediately below the step motor 69.

As a result, the transport belt 34, which has been separated from the yellow head 51Y, rises and presses the print surface of the card P toward the yellow head 51Y via the ribbon 10. Further, in synchronization with this, the control unit 40
The heating portion of the yellow head 51Y is energized to melt the ink portion of the ribbon 10 to which the yellow color has been applied, and print it on the card printing surface.

Similarly, the pulses from the position detection sensor 35 are counted for the magenta station, the cyan station, and the black station, respectively.
At the same time that the leading end of the card P has passed the heads 51 of the respective colors, the platen roller 61 pushes up the transport belt 34 that has been separated from the heads 51,
The card printing surface is pressed against the head 51 via the ribbon 10. Note that the type and number of the ink colors are not limited to those in this example, and are arbitrary.

On the other hand, the rear end of the card is
Immediately before passing through the yellow head 51Y, the conveyor belt 34 pressed against the head 51Y descends due to the downward movement of the platen roller 61Y immediately below the yellow head 51Y, and , And the printing operation in yellow is completed.

As for the magenta station and thereafter, similarly, as shown in FIG. 7, the printing operation of each color is performed through the same steps (from and after), and thereafter, the discharge unit 7 is operated, and the printed card is operated. P is discharged outside.

As described above, when there are N cards P, for each card P, through the same process, yellow,
Magenta, cyan, and black printing operations are performed, and when the Nth card P is ejected, all printing operations are completed.

Next, the operation of the platen roller 61 will be described with reference to FIGS. In the initial state, the contact position of the operating shaft 65 with the cam 68 is at the minimum cam radius position α, and the platen roller 61 is
Are separated from each other via the transport belt 34.

When the transport operation of the card P is started and a command signal for raising the platen roller 61 enters the control unit 40, the step motor 69 rotates by a predetermined pulse, and the cam 68 is transmitted via the transmission belt B. Rotates and stops at a position β for causing an arbitrarily set displacement.

At this time, since the operating shaft 65 in contact with the cam 68 is pushed up to push up the holding member 64,
The bearing member 63 is pushed up via the urging member 66. As a result, the platen roller 61 supported by the bearing member 63
Moves upward to contact the head 51 via the transport belt 34. This moving operation is performed via the urging member 66. As a result, the head 51 and the platen roller 61 come into contact with each other via the transport belt 34, the card P, and the ribbon 10, and the ink of the ribbon 10 is attached to the card P.

Immediately before the rear end of the card P passes therethrough, the step motor 69 rotates in the reverse direction by the same number of pulses as in the previous forward rotation, and the cam 68 until the operating shaft 65 contacts the initial position α. Is returned, and the holding member 64 is lowered. As a result, the bearing member 63 descends and the platen roller 61 also descends, so that the platen pressure is removed from the transport belt 34.

Next, the automatic cueing operation of the ribbon accompanying the attachment / detachment operation of the ribbon cassette 12 will be described. For example, it is assumed that the ribbon cassette 12 is once pulled out with replacement of the ribbon cassette 12 or misfeeding.

That is, in FIG. 13A, until the ribbon cassette 12 is pulled out, it slides in contact with the ribbon cassette 12, and the projection 9E maintains its position by the frictional force with the ribbon cassette 12. It was like.

However, as shown in FIG. 13 (B), the projection 9E
Does not generate a frictional force with the ribbon cassette 12, and the detection lever 9C, which has been staying at that position by the frictional force, is lowered by its own weight and the lower end is provided with the detection sensor 9D.
The descent operation stops when it is locked at. This allows
Parable, even if the power is off, the ribbon cassette 12
Is left as a history.

Next, when the ribbon cassette 12 is mounted again in the fixed position and the power is turned on, the detection lever 9C is locked to the detection sensor 9D and is turned on, and the detection signal from the detection sensor 9D is transmitted to the control unit. 40, the controller 40 outputs the first signal from the feed motor 43 and the winding motor 4.
4 and the motors 43 and 44 both start reverse rotation operation.

In this way, for example, in FIG. 9, the ribbon 10 is rewound in the reverse direction, and then the first and second sensors 81 and 82 of the ink consumption presence / absence detecting means 8 are moved to the end of the used ink portion. When passing, as shown in FIG. 10, a point where a large output difference occurs between the output signals α and β from the first and second sensors 81 and 82 of the ink consumption presence / absence detecting means 8 is detected. As a result, the control unit 40 detects the last part of the used ink portion, and the control unit 4
The output of the first signal from 0 stops immediately. Thereby, the reverse rotation operation of the feeding motor 43 and the winding motor 44 stops.

Next, a second signal is output from the control unit 40 to the feeding motor 43 and the winding motor 44, and both of them start the normal rotation operation. Then, according to the output signals from the first and second sensors 81 and 82 of the ink consumption presence / absence detecting means 8, the output difference between the signals α and β from the first and second sensors 81 and 82 is eliminated. When the control unit 40 that inputs these signals detects, the counting is performed from the time when the output signal difference disappears, and the output of the second signal is stopped when the following specific time ΔT has elapsed. ΔT = L / V Here, L represents the distance from the first and second sensors 81 and 82 of the ink consumption presence / absence detecting means 8 to the print head 5, and V represents the normal transfer speed of the ribbon 10.

Thus, the ribbon 10 stops with the cueing position of the boundary between the just used portion and the unused portion being aligned with the print head 5, and a series of cueing operations is completed.

[0058]

As described above, according to the present invention, there is provided an ink consumption presence / absence detecting means for detecting the presence / absence of ink consumption on the ink ribbon from the difference in light transmittance of the ink ribbon. This ink consumption presence / absence detection means can reliably detect the head of an unused portion of the ink ribbon, so that it is wound up unused and discarded without being used. It is economical because it disappears, and it is advantageous in terms of effective use of resources.

According to the second aspect of the present invention, there is provided a recording apparatus which uses a ribbon cassette containing an ink ribbon for printing, and detects when the ribbon cassette is mounted on the recording apparatus main body. The ink ribbon is transported after the ribbon cassette is mounted, and the ink consumption detection means detects the boundary between the last part of the used ink area and the first part of the unused ink area. A control unit is provided for stopping the operation of transporting the ink ribbon when the portion is positioned at a predetermined position of the print head unit. Therefore, it is possible to automate the cueing operation.The user can visually check that the boundary has passed when the user is bother to stop the ink ribbon transport operation, and then automatically perform the next printing operation at the boundary. Since there is no need to perform a delicate and troublesome position adjustment operation such as returning to the starting position, the usability is greatly improved.

Further, according to the third aspect of the present invention, there is provided an ink ribbon having an ink thickness substantially n times (where n is a positive integer) as compared with the ink thickness of the ink ribbon in the one-time ribbon system. The ink ribbon uses a color multi-ribbon method in which the feed speed of the ink ribbon is reduced to 1 / n of the transport speed of the recording medium, and printing is performed using the same location of the ink ribbon in 1 / n increments. In this multi-ribbon method, it is more difficult to visually check the used part than in the case of a one-time ink ribbon, so the head of the unused part can be easily missed. Since the leading portion can be reliably detected, automatic cueing can be performed particularly in the multi-ribbon mode, which is practically convenient.
