So, the toothed belt 44 can be driven by the rotation of the pulse motor 20 to thereby move the carrier 1 to the left and right in parallelism to the platen 31. Design is made such that the movement velocity v of this carrier and the movement velocity of the ink ribbon 5 driven by the pulse motor 22 for the ribbon become equal to each other in just opposite directions and even if the carrier 1 is moved, the same positions of the ink ribbon 5 and the recording paper 2 will always contact each other.

  • Figure 2 illustrates the recording control of the aforedescribed embodiment.
  • the abcissa represents the time from after the start of the movement of the carrier, and the ordinate represents the carrier velocity.
  • graph VVA shows one velocity sequence, and corresponds to the carrier driving pulse signal TCA.
  • the carrier is first accelerated to a velocity V1 at a predetermined acceleration, and is constantly moved at the velocity V1, and thereafter is decelerated at a predetermined rate.
  • the thick line portion in the graph VVA is a portion which actually effects recording (thermal heating), and starts recording after the acceleration to the velocity V1, and starts deceleration after the termination of recording.
  • the velocity V1 is, for example, of the order of 30 characters/sec.
  • Graph VVB shows another velocity sequence and corresponds to the carrier driving pulse signal TCB. According to the graph VVB, the carrier is accelerated to a different velocity V2 at the same predetermined acceleration as that previously mentioned, and is constantly moved at the velocity V2, and thereafter is decelerated at the same predetermined rate as that previously mentioned.
  • the velocity V2 is, for example, four to five times the velocity V1 (in the figure, it is shown as twice). Accordingly, the acceleration section need exceed the velocity V1 and further reach the velocity V2. Therefore, the approach run distance l3 from the start of driving to the reach to the velocity V2 and the stop distance l4 from the velocity V2 to the stoppage also become approximately four to five times, but in the present embodiment, recording is started in the vicinity of the velocity V1 in the course of acceleration and recording is continued in the section PTB1 to the velocity V2, and recording is also continued in the section PTB2 of the velocity V2 and recording is possible up to the section PTB3 in the course of deceleration.
  • the actual non-recording distance is l1 and l2 as in the prior art.
  • recording should be effected both in the course of acceleration and in the course of deceleration can be suitably selected.
  • the length of the non-recording section during the movement of the carrier 1 in which recording is not effected is made constant irrespective of the highest velocity during recording. Thereby the quality of recording can be more improved, whereas this is not restrictive, but the length of the non-recording section can be made different.

  • the CPU 10 access to the CG 13 by the character code in the RAM 12, and develops the read-out character pattern data into the IM 15.
  • a development termination address (corresponding to the recording width) is set to the THC 23 through a control line CNT, and is input to the control of Figure 3.
  • the recording width is already known from said developing process.
  • the predetermined number N is, for example, about 1/2 of the width of paper (the effective width of recording paper) in the simplest case. Or the number N is the width over which recording can be effected in the section of (PTB1 + PTB3) shown in Figure 2. Accordingly, when for example, full recording is to be effected over the width of the paper, or when the first half of one line is blank but characters are present in the latter half, or when characters or words are scattered over the width of the paper, (the recording width) > N is satisfied. When characters are present in only the first half of one line, (the recording width) > N is not satisfied.
  • step S2 If at the step S1, (the recording width) > N , at a step S2, "B" (the mode VVB) is set in the recording mode M. If at the step S1, not (the recording width) > N, at step S3, "A" (the mode VVA) is set in the recording mode M.
  • step S4 the energization signal E of the VG 17 is set to logic 1 level. Thereby the carrier 1 starts its acceleration.
  • the energization signal E of the VG 17 is set to logic 0 level.
  • the energization signal E of the VG 17 is not set to logic 0 level, there will be no problem, because in any case, at the terminal and of the paper width, the carrier stops without fail in accordance with the velocity sequence VVB (or VVA) of Figure 2.
  • setting the energization signal E to logic 0 level has the following advantage.
  • the velocity sequence VVA of Figure 2 can start deceleration at any point of time whereat recording is terminated, whereby the efficiency of the carrier demand scanning is improved.
  • deceleration can be started as indicated by a line Q at any point of time whereat recording is terminated.
  • moving means for moving the recording unit of the present embodiment in accordance with a predetermined velocity sequence not only refers to a construction comprising the VG 17, etc. of Figure 1, but also includes means for realizing the function of detecting the velocity V1 and then recording at this constant velocity V1, or the function of detecting the velocity V1 and then recording up to the velocity V2 and continuing to record at this constant velocity V2.
  • Figure 5 shows an example of the recording by the aforedescribed embodiment.
  • the reference numeral 100 designates a line which does not satisfy (the recording width) > N.
  • recording is effected in the graph VVA mode of Figure 2.
  • Lines 101 and 102 are lines which satisfy (the recording width) > N. In these cases, recording is effected in the graph VVB mode of Figure 2.
  • the thermal head 4 may be once floated from the recording paper 2 for saving of the recording ribbon 5 and the ribbon may not be fed in that section (so-called skip function).
  • the carrier motor may be any of pulse motor, a DC motor, etc.
  • the timing for applying heat in the case of a pulse motor, heat may be applied in synchronism with the change-over timing of the excitation phase, and in the case of a DC motor, heat may be applied in synchronism with the signal timing of an encoder or the like, whereby record at a predetermined pitch (or ordinary natural images) may be obtained irrespective of acceleration, constant velocity or deceleration.
  • the heat dot is renewed in conformity with the angle of rotation of the pulse motor or the DC motor even during acceleration or deceleration as well as during constant velocity movement and therefore, images of a predetermined pitch are always obtained.
  • the heat pulse width use is made, for example, a heat pulse width which satisfies the velocity V2 so that uniform density may be obtained in the entire recording section.
  • the velocity modes are two, i.e., V1 and V2, this is not restrictive, but V3, V4,... may further be added to thereby provide multiple velocity modes. It is also possible to set the change-over set values N2, N3,... of the recording width finely in conformity with them.
  • design is made such that in the graph VVB mode of Figure 2 wherein printing is effected at the velocity V2, recording is executed in both of a section PTB1 in the acceleration area and a section PTB 3 in the deceleraton area, but design may also be made such that one of these sections is not recorded.
  • the change-over set value N of the recording width may be suitably determined and the recording speed may be automatically changed over to V1 and V2 by N and recording may be effected, whereby a higher speed of recording can be realized.
  • Figure 6 is a perspective view showing an embodiment of the ink jet recording apparatus to which the present invention is applied as in the aforedescribed embodiment.

  • This system is applicable to both of the so-called on-demand type and the so-called continuous type, and is particularly effective in the case of the on-demand type because at least one driving signal corresponding to recording information and providing a rapid temperature rise exceeding nuclear boiling is applied to an electro-thermal converting member disposed correspondingly to a sheet or a liquid path in which liquid (ink) is retained whereby heat energy is generated in the electro-thermal converting member and film boiling is caused on the heat-acting surface of the recording head with a result that a bubble in the liquid (ink) can be formed in one-to-one correspondence to the driving signal.
  • the liquid (ink) is discharged through a discharge opening to form at least one droplet.
