The present invention allows the current to pass through the resistant material layer so that the resistant ribbon and the ink layer consisting of a resistive materia1 layer and a thermally molten ink layer are selectively melted and transferred to a receptor such as paper. The present invention relates to a resistant ribbon heat transfer printing apparatus using a plurality of electrodes which are selectively applied.

As a heat transfer printing technology known as low cost and high quality printing technology, resistant ribbon heat transfer printing technology is K.S. Penningtong's "Resistant ribbon heat transfer printing, its historical review and introduction of new printing technology" [IBM J.RES.DEVELOP VOL. No. 5 September 1985].

The basic method for applying a voltage to a plurality of electrodes is to apply voltage pulses of the same pulse width to the electrodes to simultaneously print dots as shown in FIG. 17A. In FIG. 17A, the print data "W" indicates "white" where no voltage is applied to the corresponding electrode, and the print data "B" indicates "black" for printing dots (dots) by applying a voltage to the corresponding electrode. (Black) ". In this method, however, the flow of current through a portion of the resistant material layer under the voltage-applied electrode between two adjacently-applied electrodes is below the voltage-applied electrode and the adjacent voltage-applied electrode. It is different from the flow of current through a part. The currents resulting from the flow of two recognized voltages by the applied electrodes interfere with each other and are reduced by each other. However, the current resulting from the flow of the approved voltage to the electrode to which no voltage is applied passes through a wider area than the area where the current flows by the electrode to which voltage is applied between two adjacent voltage applied electrodes. This makes the printed dots non-uniform, as shown in FIG. 17 (b) showing the printed image by the pulses shown in FIG. 17 (a). In FIG. 17 (b), the dots formed by the electrode blocks 2 and 5 are larger than those formed by the electrode numbers 3 and 4. As shown in FIG.

To solve this problem, a time-division voltage application method is introduced as shown in Japanese Patent Application Laid-open No. 59-167279. In this method, a plurality of electrodes are divided into blocks, and as shown in FIG. 18, the electrodes of each block are time-divided by time-dividing pulses. This method solves the above problem with non-uniformly printed images, but has another problem. This problem is that the printing speed is slowed due to time division driving, and another problem is that the linearity of the printed image is worse because the voltage is applied at different times at different electrodes. Another problem is that the resistant ribbon is damaged by the impact of large pulsed currents flowing through small areas in a short time.

An object of the present invention is to provide a resistant ribbon heat transfer printing apparatus capable of printing an image of uniform dot size and excellent linearity at high speed.

To this end, the resistant ribbon heat transfer printing apparatus according to the present invention uses a resistant ribbon made of the resistant material layer and an ink layer in contact with the surface of the receiving member on which the image is recorded; A print head having a plurality of recording electrodes and one common electrode arranged at a spaced interval between the recording electrodes, and the recording and common electrodes contacting the resistant material layer of the resistant ribbon; A drive unit for moving at least one of the resistant ribbon and the print head relative to each other; A voltage application circuit for selectively applying a voltage to a plurality of write electrodes at substantially the same time by electric pulses; And a control unit for controlling the voltage application circuit in accordance with the data to be printed. The control unit causes the voltage application circuit to be disposed between two recording electrodes to which a voltage is applied, and to apply a predetermined energy to the recording electrode to which the voltage is applied. The branch allows a normal electric pulse to be applied, and causes the voltage applying circuit to apply a non-electromagnetic pulse of less energy than the normal electric pulses to the recording electrode to which the voltage is applied but not disposed between the two recording electrodes to which the voltage is applied. To do that.

In a preferred embodiment, each stationary electric field is a single voltage field of a predetermined pulse width, and the nonelectromagnetic field is a single voltage pulse that has a pulse width smaller than the stationary voltage pulse and occurs while the stationary voltage pulse is sustained.

In another preferred embodiment, each nominal voltage pulse is divided into at least two consecutively occurring subpulses, the non-voltage pulse removing at least one subpulse, preferably one which occurs earlier, from the nominal voltage pulse. Obtained.

In another preferred embodiment, each normal electric pulse is a single electric pulse, and the non-electric pulse is generated by delaying the normal current pulse by a predetermined time so that a portion of the non-electric pillar overlaps with a portion of the normal current pulse (overlapped). )do.

In another preferred embodiment, normal and non-electric pulses are generated in accordance with both the printed data and the first printed data.

The above and other objects of the present invention will become apparent from the following description with reference to the accompanying drawings.

1 shows the outline of an embodiment of a Resistive Ribbon Thermal Transfer printing apparatus (hereinafter referred to as RRTT printer) according to the present invention. A ribbon cartridge 4 having the printhead 1 and the resistant ribbon 5 stored therein via a valve 6 to the motor 7 to move back and forth along the guide bar 3. It is mounted on a carriage 2 which is driven by it. The paper sheet 8 is supplied between the platen 9 and the resistant ribbon 5.

During printing, the printhead 1 is pressed onto the resistant ribbon 5 so that the printhead 1 remains in contact with the ribbon 5 and the resistant ribbon 5 remains in contact with the paper 8. The resistant ribbon 5 is moved in one direction in synchronization with the printing operation by a known mechanism such as that used in conventional typewriters.

2 and 3 show the main parts of the RRTT printer shown in FIG. The inso-head 1 has one common electrode 11 and a plurality of recording electrodes 10 spaced apart from the common electrode at a fixed distance. In the illustrated embodiment, eight recording electrodes 10a to 10h are disposed in one straight line parallel to the common electrode 11. The resistant ribbon 5 has a resistant material layer 12 made of a resin such as two carbon-containing polar carbonates, and an ink layer 13 made of thermally meltable ink. The common electrode and the recording electrodes are in contact with the surface of the resistant material layer side of the resistant ribbon 5. The ink layer side surface of the resistant ribbon 5 is in contact with the paper 8 shown in Fig. 1 but not shown in Figs.

In the embodiment shown in FIG. 1, the resistant ribbon 5 is in the direction of the arrow 40 in FIG. 2 so that the relative position of the recording head relative to the resistant ribbon moves in the direction from the recording electrode side to the common electrode side, or The relative position of the recording head relative to the resistant ribbon is shifted in the direction shown by the arrow 41 in FIG. 2 so as to shift from the common electrode side to the recording electrode side. The direction of movement of the print head relative to the resistant ribbon is perpendicular to the line on which the recording electrodes are arranged. In contrast, the resistant ribbon is fixed and the printhead may move in the direction 41 or the direction 40.

A voltage is applied to the recording electrode in the head drive circuit 14 under the control of a control unit 15 between each recording electrode 10a to 10h and the common electrode 11 of the print head 1. Voltage pulses are optionally supplied.

A representative shape of the head drive circuit 14 and the control unit 15 is shown in FIG. The head drive circuit 14 is connected to each of the recording electrodes 10a to 10h at the collector terminal of each of the transistors, and at its emitter terminal the common electrode 11 at its ground terminal. Is composed of a plurality of switching transistors 16 commonly connected to the power source 18 connected to the < RTI ID = 0.0 > Each of the switching transistors is turned on in response to a negative logic voltage pulse applied to the base terminal of the control unit 15 to apply a voltage to the corresponding recording electrode connected to the collector terminal thereof. on)

The control unit 15 includes a memory 21 storing data to be printed therein, a microprocessing unit (MPU) 20 which entangles a print data from the memory 21 and produces drive data and control signals. It consists of a drive control circuit 19 which is controlled by a control signal which produces negative logic drive pulses to drive the switching transistor 16 from the data.

5 shows an example of drive data produced by the MPU 20 when the relative position of the print head relative to the resistant ribbon moves in the direction from the recording electrode side to the common electrode side. Positive logic pulses shown in FIG. 5 are polarized by the drive control circuit 19 to become negative logic drive pulses. The driving data (a) to (h) are for applying voltages to the recording electrodes 10a to 10h, respectively. Print data "W" represents "white" (corresponding to logic "0") in which dots are not printed, and print data "B" represents "black" (corresponding to logic "1") in which dots are printed. Pulses each having a pulse width T1 are generated at the same time, and are called normal pulses. Pulses each having a pulse width T2 are generated at a time delayed by (T3) from the leading edge of the normal pulse and are called "specific pulses". The normal and buff pulses terminate at the same time. That is, T1 = T3 + T2.

The normal pulse is also used to apply a voltage to the recording electrode disposed between the two recording electrodes to which the voltage is to be applied. The non-pulse is also used to apply a voltage to the recording electrode which is not disposed between the two recording electrodes to be applied. This pulse selection method will be readily understood from FIG.

The MPU 20 produces the drive data shown in FIG. 5 according to the program shown by the flowchart of FIG. In step 101, printing date is read out from the memory 21 as data A, which is " 1111100 " in the case of FIG. In step 102, data A is shifted right by one bit, resulting in data B of " 111110 ". In step 103, data A is shifted left by one bit, resulting in data C of " 11111000 ". In step 104, a logical AND operation of A · B · C is executed to obtain data D of “111000”. Therefore, the step which consists of steps 011-104 is the data D which calculates all the steps 100. As shown in FIG. In step 200, the MPU 20 outputs the data D to the drive control circuit 19 during the period T3. In step 300, the MPU 20 outputs data A to the drive control circuit 19 during the period T2. As a result, the pulses shown in FIG. 5 are produced and the polarity is reversed in the drive control circuit 19 to become negative logic pulses, which are respectively applied to each base terminal of the switching transistor 16, respectively. In response to the negative logic pulse having the same logic as that shown in FIG. 5, the switching transistor 16 applies a voltage pulse corresponding to the pulse shown in FIG. 5 to the recording electrode.

Each of the voltage pulses applied to the recording electrodes 10b and 10f, corresponding to the non-pulse of FIG. 5, corresponds to the voltage pulses applied to the recording electrodes 10c to 10e, corresponding to the normal pulses of FIG. They have less energy than each one of them. The current caused by flowing through the resistant material layer of the resistant ribbon by each of the recording electrodes 10c to 10e to which voltage is applied by the normal voltage pulse is applied to two adjacent voltages to reduce the area of flow. Are interacted with by the current caused by the flow. The current due to flowing by each of the recording electrodes 10b and 10f to which voltage is applied by the non-voltage pulses is acted only by the current due to flowing by one adjacently applied voltage to its voltage. The flow area is less reduced. However, since the energy given by the non-voltage pulse is smaller than that given by the normal voltage pulse and the timing is different therefrom, the area under which the current flows under the recording electrode to which the voltage is applied by the non-voltage pulse is determined by the normal voltage pulse. It is almost equal to the area where the reduced current flows under the recording electrode to which the voltage is applied. In other words, the non-voltage pulses and the normal voltage pulses are selectively applied to the recording electrode, so that the current caused by the flow of the voltage applied to each of the electrodes becomes uniform, allowing the size of the printed dots to be the same. Therefore, a high quality image can be printed.

In addition, since all the recording electrodes to be applied with the voltage are applied at the same time, the printing speed is faster than that of the time division driving system. Also, since the pulse width of the applied pulse can turn relatively larger than the time division drive system, the immunity ribbon will not be damaged by the current pulses flowing there.

Normal electric pulses and non-electric pulses for selectively applying a voltage to the recording electrode in order to obtain the above-described effect can be produced by the other methods described below.

FIG. 7 shows another example of the drive data when the position of the print head relative to the resistant ribbon moves in the direction from the recording electrode side to the common electrode side. In FIG. 7, the normal pulse has two subpulses, namely, a first subpulse having a pulse width T4 and a pulse width T2 at the trailing edge of the first subpulse (T5). Divided by a second pulse delayed by. The non-pulse is the same as the second sub pulse of the normal pulse and occurs at the same time as the second sub pulse.

FIG. 8 shows a flowchart of a program executed in the MPU 20 to produce the pulses shown in FIG. In step 100, the same data D as described with reference to FIG. 6 is produced. In step 210, the MPU 20 outputs data D for a period T4. In step 220, the MPU 20 outputs data of assorted bits " 0 " during the period T5. In step 300, the MPU 20 outputs this print data A during the period T2.

FIG. 9 shows an example of drive data when the position of the print head relative to the resistant ribbon moves from the common electrode side to the recording electrode side, that is, in the opposite direction to the case of FIG. In FIG. 9, the non-pulse is generated at the same time as that of the normal pulse, but ends at the time preceding the tail edge T3 of the normal pulse. The pulses shown in FIG. 9 may be made by reversing the order of steps 200 and 300 shown in the flowchart of FIG. 6 as shown in FIG.

When the print speed is increased, the temperature rise of the printhead also increases due to the heat transferred in the heated resistant ribbon. Excessive temperature rise of the printhead causes a bad effect on print quality. In this case, differently from the viewpoint, the area of the resistant ribbon heated for printing has been heated to a certain extent by the heat generated during the preceding printing operation. This means that the voltage can be applied with less energy than the recording electrode to which the voltage is to be applied next is normally required. In the above viewpoint, pulses for applying a voltage to the recording electrode can be produced according to the previous print data as well as the present print data. FIG. 11 shows an example of drive data that satisfies this condition when the relative position of the print head relative to the resistant ribbon moves in the direction from the recording electrode side to the common electrode side.

In FIG. 11, each period T in which one printing operation for printing one print data is performed is performed in the first period T4 for the four periods-the first subpulse, and the first period T4 with no subpulse at all. It is divided into two periods T5, a third period T2 for the second subpulse, and a fourth period T6 for the third subpulse. In this figure, although the spacings between (T2) and (T6) and between the ends of (T6) and (T) are illustrated, they are from the first and second subpulses in the next period T. It is intended to clarify the distinct third subpulse, not actually. The normal pulse for the normal voltage application is composed of the first to third sub pulses, and the non-pulse for the normal voltage application is composed of the second and third sub pulses.

The first and second subpulses are produced according to the same rules between normal pulses and nonpulses as described above. That is, both the first and second subpulses are produced for applying a voltage to a recording electrode disposed between two adjacent recording electrodes to which a voltage is applied and to which voltage is to be applied, and only the second subpulse produces a voltage. It is produced for applying a voltage to a recording electrode that is applied and not disposed between two recognized recording electrodes to which a voltage is to be applied.

The third sub-pulse is produced only when the recording electrode to which the voltage is applied by the present print data is not applied by the first print data. Data for producing the third subpulse can be obtained from the preceding print data by the present print data and the calculation described below.

FIG. 12 shows a flowchart of a program executed in the MPU 20 to produce the pulses shown in FIG. Here, if the present print data denoted as data A is the fifth of the five print data shown in Fig. 11, the previous print data which is earlier in Fig. 11 is indicated by data E. Data A is "10111010" ("BWBBBWBW") and data E is "10010010" ("BWWBWWBW").

MPU(20)는 스텝(210)에서 기간(T4)동안 데이터 D를, 스텝(22O)에서(T5)동안 모든 데이터"0"을, 스텝(300)에서 (T2)동안 데이터 A를, 제 8 도에 도시된 것과 같은 방법으로 출력한다. 그후, 스텝(500)에서, MPU(20)는 기간(T6)동안 데이터 G를 출력한다. 이 방법으로, 제 11 도의 마지막 인쇄기간(T)에 도시된 바와같은 펄스들이 생산될 수 있다.In FIG. 12, the same data D as shown in FIG. 6 is generated in step 100, where D = 10000 ". In step 401, the preceding print data F is data F

Is inverted to " 1101101 ". In step 402, a logical AND operation of AF is performed to obtain data G (= A · F) = " 101000 ". This data G calculated in step 400 consisting of steps 401 and 402 is data for producing the third subpulses of FIG. The MPU 20 receives data D for a period T4 at step 210, all data " 0 " Output in the same manner as shown in FIG. Thereafter, in step 500, MPU 20 outputs data G for a period T6. In this way, pulses as shown in the last printing period T of FIG. 11 can be produced.

The driving method described with reference to FIGS. 11 and 12 is effective in preventing the print head from being excessively heated during the high speed printing operation.

As described above, the recording electrode is applied with a voltage by a voltage pulse applied thereto. Alternatively, the voltage may be applied by the current pulse supplied to the recording electrode. 13 shows an embodiment in which a voltage is applied to the recording electrode by a current pulse. In the embodiment shown in FIG. 13, the constant current generating circuit 22 of the head drive circuit 14 is connected between each collector terminal of the switching transistors 16 and the recording electrodes 10a to 10h, respectively. Only in shape differs from the embodiment of FIG. Each of the constant current generating circuits 22 generates a constant current pulse corresponding to the voltage pulse applied thereto to apply a voltage to the recording electrode connected thereto.

FIG. 14 shows a representative circuit configuration of each of the constant current generating circuits 22. As shown in FIG. The input terminal 23 is connected to a collector terminal corresponding to one of the switching transistors 16. The output terminal 24 is connected to the corresponding one of the recording electrodes 10a to 10h. The resistor 25 is connected to the input terminal 23 at one terminal and to the emitter terminal of the transistor 26 and the inverting input terminal of the operational amplifier 27 at the other terminal. The non-inverting input terminal of the operational amplifier 27 is connected to the connection point of the Zener diode 29 and the resistor 30 connected in series between the input terminal 23 and the ground to maintain a constant voltage at the connection point. . The output terminal of the operational amplifier 27 is connected to the base terminal of the transistor 26 via the resistor 28. The collector terminal of the transistor 26 is connected to the output terminal 24. The operational amplifier 27 operates to maintain a constant voltage across the resistor 25 so that when a voltage pulse is applied to the input terminal 23, a constant current is passed through the resistor 25 and the transistor 26 to the output terminal 24. Flow.

FIG. 15 shows an example of drive data for applying a voltage to the recording electrode with the configuration shown in FIG. Normal pulses occur during the period T1. Since the non-pulse occurs for a period T2 delayed by the front edge of the normal pulse (T3), the non-pulse over wraps the normal pulse during the period T8. The length of (T1) is equal to the length of (T2). Therefore, the time difference T9 between the tail edge of the normal pulse and the tail edge of the non-pulse is equal to the length of T3. In other words, the non-pulse can be regarded as a pulse obtained by delaying the normal pulse by (T3). The example shown in FIG. 15 is effective when the relative position of the print head relative to the resistant ribbon moves in the direction from the recording electrode side to the common electrode side.

FIG. 16 shows a flowchart of a program executed in the MPU 20 to produce the drive pulse shown in FIG. In step 100, the same data D as shown in Fig. 6 is produced, i.e., data A = " 1111100 " and data D = " 00111000 ". In step 601, data D is inverted such that data H = " 11000111 ". In step 602, a logical AND operation of A · H is performed to obtain data I = A.H = “1000100”. The MPU 20 outputs data D for a period T3 at step 700, data A for step T8 at step 800, and data I for step T9 at step 900.
