DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

In the embodiment described below, the traveling unit causes the recording unit to travel in accordance with a speed sequence of, for example, constant acceleration, high speed constant traveling, and constant deceleration. On the other hand, the recording means performs recording at each dot timing according to the speed sequence of the constant acceleration, high-speed constant traveling, and constant deceleration by the traveling means.

Preferably, the speed sequence (particularly the maximum speed) differs depending on the recording width of the recording line.

Preferably, the gradient of the acceleration or deceleration of the speed sequence is the same.

FIG. 4A is a conceptual diagram of a recording unit of a thermal printer to which one embodiment of the present invention is applied, and FIG. 4B is a plan view of the thermal printer. (Note that in FIG. 4 (B), the recording unit is also shown in more detail than FIG. 4 (A), but the function is the same.) The carrier motor 20 is set to a predetermined speed sequence. Accordingly, by controlling the rotation, the carrier 1 on which the thermal head 4 is mounted is constantly accelerated in the direction indicated by arrow 3, is driven at a constant high speed, and is constantly decelerated. Then, at a timing corresponding to the carrier speed at each time point, the heating element selected according to the recording information is heated from the plurality of heating elements 4a included in the thermal head 4, and the ink included in the ink ribbon 5 is transferred to the recording paper 2. Then, recording is performed on the recording paper 2.

On the other hand, in conjunction with the constant acceleration, high-speed constant traveling, and constant deceleration of the carrier 1, the constant acceleration, high-speed constant traveling, and constant deceleration of the take-up reel (ribbon pancake) 6a in the direction of the arrow 7 are matched. This prevents the occurrence of rubbing between the ink ribbon (thermal ribbon) 5 and the recording paper 2.

Here, with reference to FIG. 4 (B), a Sarl printer to which an embodiment of the present invention is applied will be described in more detail.

In FIG. 4 (B), reference numeral 31 denotes a platen, which is formed of a rubber material. The thermal head 4 is pressed against the platen 31 by the elastic force of a spring 35 with the ink ribbon 5 and the recording paper 2 sandwiched between the thermal head 4 and the platen 31. The ink ribbon 5 is disposed on the carrier 1 and is wound from a supply reel 6b to a take-up reel 6a via the thermal head 4 on the carrier 1. At one end of a lever 38 that rotates about a shaft 37 on the carrier 1,
A spring 39 is hung between the carrier 1 and the lever 38.
Is rotated clockwise around the axis 37. At the other end of the lever 38, a ribbon pulse motor 22 is mounted. A ratchet 41 is fixed on the motor shaft 22a, and the pawl 41 and the ink ribbon 5 wound on the take-up reel 6a are engaged with each other by the tension of the spring 39 of the lever 38, and the motor 38 stops. , Regardless of the winding diameter of the ink ribbon 5, the ink ribbon 5 is arranged at a position where it always comes into contact.

Now, the carrier 1 has fixed shafts 42, 4 parallel to the platen 31.
3 and moves the thermal head 4 in parallel with the platen 31. Further, the toothed belt 44 having one end fixed to the carrier 1 has the other end connected to the carrier 1 via pulleys 45 and 46.
It is stuck to. Further, a gear 47 is formed integrally with the pulley 45, and this gear 47 is an axis of the carrier pulse motor 20.
It is engaged with a gear 39 fixed on 20a. Therefore, the rotation of the pulse motor 20 drives the toothed belt 44 to move the carrier 1 left and right in parallel with the platen 31. The moving speed v is equal to the moving speed of the ink ribbon 5 by the ribbon pulse motor 22 in the opposite direction, so that the same portion always contacts the ink ribbon 5 and the recording paper 2 even if the carrier 1 moves. Is configured.

In the figure, reference numeral 10 denotes a CPU, which performs main control of the thermal printer. Reference numeral 11 denotes a ROM which stores, for example, a recording control program shown in FIG. Reference numeral 12 denotes a RAM, which stores a character code for recording and is used by, for example, the CPU 10 as a work area.

Reference numeral 14 denotes recording data input means for inputting recording data from a host system (not shown) or a keyboard. Reference numeral 15 denotes an image memory (IM) which stores a dot pattern image of the recording row developed by the CPU 10. Reference numeral 16 denotes an I / O port (I / O) which decodes and outputs instructions of the CPU 10. 17 is speed sequence generation means (VG)
And outputs voltage signals VVA / VVB of different speed sequences according to the speed sequence designation mode M from the CPU 10. Reference numeral 18 denotes a voltage frequency conversion means (VFC), which is a pulse signal train T having a frequency corresponding to the speed sequence voltage signal VVA / VVB.
Output CA / TCB. 19 is the carrier motor control circuit (CM
D) and outputs a phase clock signal for driving the carrier motor (CM) 20 according to the pulse signals TCA / TCB. Reference numeral 20 denotes a carrier motor (CM), for example, a pulse motor. Reference numeral 21 denotes a ribbon motor control circuit (RMD), which is a pulse signal TRA / T related to the pulse signal TCA / TCB.
It outputs a phase signal for driving the ribbon motor (RM) 22 according to RB. A thermal recording control circuit (THC) 23 reads out recording data (ID) from the IM / 15 according to the pulse signal TTA / TTB related to the pulse signal TCA / TCB, and uses the ID to record the thermal head (THC). ) 4 is driven to generate heat.

FIG. 2 is a diagram for explaining the recording control of the embodiment.
The horizontal axis is the time from the start of the carrier movement, and the vertical axis is the carrier speed. In the figure, a graph VVA shows one speed sequence and corresponds to the carrier drive pulse signal TCA. According to the graph VVA, first the velocity V ₁ at a constant acceleration
To accelerate and constant speed running at the speed V _1, then decelerated at a constant rate. The thick line in the graph VVA is a part for actually recording (thermal heat), to start recording after accelerated to speed V _1, has started decelerating after recording is completed. Velocity V ₁ was, for example, about a conventional similar 30 characters / sec., Rises to the speed V ₁ is pulled out the maximum torque characteristics of Kiyariamota 20 from driving start. Approach distance (non-recording distance) l ₁ in this case is the practical distance, conventionally likewise relatively short (about 3 to 5 mm). The same applies to the stopping distance (non-recording distance) l _2.

The graph VVB shows the other speed sequence and corresponds to the carrier drive pulse signal TCB. According to the graph VVB, first, the same constant acceleration and different speeds V
It accelerates to _2, and the constant speed traveling at the speed V _2, decelerated in the subsequent constant rate of the same. Velocity V _2, for example 4 to the velocity V ₁
5 times (the figure is shown as 2 times).

Accordance connexion, acceleration section must lead to further speed V ₂ greater than the speed V _1. Therefore, the run-up from the start of driving up to the speed V ₂ distance l ₃ and stopping distance l ₄ from the speed V ₂ until it stops also becomes 4-5 times respectively substantially, the speed V of the middle acceleration in this embodiment ₁ starts near the recording, recorded continues in section PTB ₁ leading to velocity V _2, and continue recording more even intervals PTB ₂ velocity V _2,
It is possible to record up to section PTB _{3 during} deceleration. Therefore, even in this case, the actual non-recording distances are l ₁ and l ₂ as in the conventional case.

Whether or not to perform recording during acceleration or deceleration may be appropriately selected. For example, recording may be performed during acceleration or deceleration and during constant speed traveling.

In the present embodiment, as shown in the graphs VVA and VVB, the length of the non-recording section where no recording is performed during the movement of the carrier 1 is constant regardless of the maximum speed during recording, and the acceleration is also set. It was fixed. As a result, the speed V2
In the case of recording at a speed of V1, the recording can be accelerated with the same acceleration without difficulty, so that the recording medium is not adversely affected by residual vibration or the like after the acceleration of the carrier, and it is possible to prevent a decrease in recording quality. Of course, by keeping the acceleration constant, the time required to reach the speed V2 increases, but even during this acceleration period, since the recording is performed in a section other than the non-recording section of a fixed distance, the non-recording section increases. Never.

As described above, according to the present embodiment, when a short sentence is recorded from the beginning of a line, recording is performed in accordance with the speed mode VVA, and when performing short recording, recording is performed in accordance with the speed mode VVB. As shown in the figure, since the time difference between the two is small, recording can be performed at a much higher speed than in the related art.

FIG. 3 is a flowchart of the recording control program of the embodiment. In advance, the CPU 10 uses the character code in the RAM 12
13 and read the read character pattern data into IM15.
Expand to When the development for one line of records is completed,
The development end address (corresponding to the recording width) is set for the THC 23 via the control line CNT, and is input to the control shown in FIG.

In step S1, it is determined whether or not (recording width)> N.
The (recording width) is already known by the above-described developing process. In the simplest case, the predetermined number N is, for example, approximately half of the sheet width (effective recording sheet width). Or (PTB ₁ + PT
B ₃ ) The width that can be recorded in the section). Therefore, for example, when full recording is performed over the paper width, when the first half is blank but there are characters in the second half, or when characters or words are scattered across the paper width, etc. (recording width) > N is satisfied. If there are characters only in the first half of the line, (recording width)> N is not satisfied. When the discrimination of step S1 (recording width)> N, the recording mode M is changed to “B” (VVB) in step S2.
Mode). If (recording width)> N is not satisfied, "A" (VVA mode) is set to the recording mode M in step S3. In step S4, the activation signal E of VG17 is set to the logic 1 level. This causes the carrier 1 to start accelerating. Step S5 waits for (carrier speed = V ₁ ) via the sense line (SEN) of THC23. THC23 has a speed signal VVA
Since / signal TTA / B associated with B is entered, it detects the speed V ₁ from the signal period. Of course, it may be detected velocity V ₁ in other ways. (Carrier speed = V ₁ ), the process proceeds to step S6, and the read / write control in THC23 is activated (C
NT ← Start). As a result, the THC reads out the pattern data sequentially from the first address of the IM 15 and drives the thermal head 4 to overheat in synchronization with the pulse signal TTA / B. In step S7, the process waits for the end of recording (SEN = END) via the sense line SEN. That is, the recording ends when the read address (AD) in the THC 23 reaches the preset development end address (recording width). Step S8
Then, the activation signal E of VG17 is set to the logic 0 level.

Note that there is no problem even if the activation signal E of VG17 is not set to the logic 0 level in step S8. In any case, at the end of the paper width, the speed sequence VVB (or VVB) shown in FIG.
This is because it must stop according to A). On the other hand, setting the activation signal E to the logic 0 level has the following advantages. For example, in the speed sequence VVA shown in FIG. 2, even if the deceleration is started at the end of an arbitrary recording, the efficiency of the carrier demand scanning is improved. Also in the case of the speed sequence VVB, deceleration can be started at the end of arbitrary recording as indicated by the line Q in the drawing.

Accordance connexion, and the traveling means for the recording unit of the present embodiment is accordance connexion traveling a predetermined speed sequence, not only refers to a structure consisting of VG17 etc. of Figure 1, broadly, the from the detection of the speed V ₁ ability to record at a constant speed V _1, or the speed V ₁ and recorded from the detection to the speed V _2, and including means for implementing a function of recording continues in the constant speed V _2.

FIG. 5 is a diagram showing a recording example of the embodiment. In the figure, 100 is a row that does not satisfy (recording width)> N. In this case, recording is performed in the graph VVA mode shown in FIG. Also row 1
Lines 01 and 102 satisfy (recording width)> N. In this case, recording is performed in the graph VVB mode shown in FIG.

If there is a relatively large blank portion in the middle of a recording line as in the line 102, the thermal head 4 may be temporarily lifted off the recording paper 2 so that the ribbon feed is not performed in that section in order to save the recording ribbon 5. (So-called skip function).

The carrier motor may be a pulse motor, a DC motor, or the like. The timing for applying heat is synchronized with the excitation phase switching timing in the case of a pulse motor, and the signal timing of an encoder or the like in the case of a DC motor. By applying heat in synchronism with the above, recording at a predetermined pitch (a general natural image may be performed) is obtained regardless of whether the vehicle is accelerating, constant speed, or decelerating. For example, one step of the carrier motor corresponds to (1/360) inch / pitch on paper,
Also, if the dot pitch of the image is (1/360) inch / pitch, the heat dot is updated according to the rotation angle of the pulse motor or DC motor, not only during constant speed running but also during acceleration or deceleration, so that an image with a constant pitch is always obtained. Can be Incidentally, the heat pulse width is so uniform density can be obtained in all the recording interval, for example using a heat pulse width satisfying the velocity V _2.

In addition, although it is originally possible to record even in a non-recording section, that is, immediately after the start of the movement of the carrier 1 or immediately before the stop of the carrier 1, actually there is inertia, deflection, backlash and the like of the mechanical section. Is unstable, and therefore is not adopted in this embodiment.

Further, in the above-described embodiment, the speed mode is set to _two of V ₁ and V ₂ , but is not limited to this. Further, V ₃ , V ₄ ... May be added to set the multi-speed mode.

In addition, it is possible to finely set the recording width switching set values N ₂ , N ₃ ,.

In the above embodiments, printing at a speed V _2, in the graph VVB mode in the second view, the section PTB ₁ in the acceleration region, are configured so as to perform both recording the section PTB ₃ in the deceleration region, It may be configured to perform recording without recording the section of the PTB ₂ regions only. Also in this case, the recording width switching set value N is appropriately determined, and
By performing automatic switched recorded the recording speed in V _1, V ₂ by N, faster recording can be realized.

Further, another embodiment will be described with reference to FIG.
FIG. 6 is an external perspective view showing an example of an ink jet recording apparatus to which the present invention is applied in the same manner as in the above embodiment. Note that members having the same functions as those in the above-described embodiments are given the same reference numerals, and the description is referred to.

In FIG. 6, reference numeral 50 denotes a head cartridge, in which a recording head constituted by using a heater board and an ink tank serving as an ink supply source are integrated. The head cartridge 50 is detachably fixed on the carrier 1 by a holding member 61.
Reciprocating in the longitudinal direction along 3 is possible. The ink ejected from the ejection opening of the recording head reaches the recording paper 2 whose recording surface is regulated by the platen 31 at a minute interval from the recording head, and records an image on the recording paper 2.

An ejection signal corresponding to image data is supplied to the recording head from an appropriate data supply source via a cable 56 and a terminal (not shown) connected thereto. Head Cartridge
The number 50 may be one or more (two in the figure) depending on the ink color or the like to be used. The recording head has an electrothermal transducer, and the heat generated by the electrothermal transducer causes film boiling, thereby forming bubbles in the ink. Eject ink from the. Also, 60 is a feed motor, and a gear
The platen roller 31 is rotated via 60a and 60b. In addition, 6
A switch 2 turns on and off the power supply of the ink jet recording apparatus.

The above-described embodiment provides excellent effects particularly in a recording apparatus to which a valve jet recording method is applied among the ink jet recording methods.

Regarding the representative configuration and principle, it is preferable to use the basic principle disclosed in, for example, US Pat. Nos. 4,723,129 and 4,740,796.
This method can be applied to both the so-called on-demand type and the continuous type. In particular, in the case of the on-demand type, it is arranged corresponding to the sheet or the liquid path holding the liquid (ink). By applying at least one drive signal corresponding to the information to be recorded and giving a rapid temperature rise exceeding nucleate boiling to the electrothermal transducer, heat energy is generated in the electrothermal transducer, and the recording is performed. This is effective because the film is boiled on the heat acting surface of the head, and as a result, bubbles in the liquid (ink) can be formed one-to-one corresponding to this drive signal. By discharging the liquid (ink) through the discharge opening by the growth and contraction of the bubble, at least one droplet is formed. When the drive signal is formed into a pulse shape, the growth and shrinkage of the bubble are performed immediately and appropriately, so that the ejection of the liquid (ink) having particularly excellent responsiveness can be achieved, which is more preferable. U.S. Pat. No. 4,463,359 describes this pulsed drive signal.
Nos. 4,345,262 and 4,345,262 are suitable.

If the conditions described in US Pat. No. 4,313,124 of the invention relating to the temperature rise rate of the heat acting surface are adopted, more excellent recording can be performed.

No. 4,558,333 and U.S. Pat. No. 4,459,600 which disclose the configuration in which the is bent are also applicable to the above embodiment. In addition, JP-A-59-123670 discloses a configuration in which a common slit is used as a discharge portion of an electrothermal converter for a plurality of electrothermal converters, and an aperture for absorbing pressure waves of thermal energy. The above-described embodiment is effective even if the configuration is based on Japanese Patent Application Laid-Open No. 138461/1984, which discloses a configuration corresponding to a discharge unit.

In addition, a replaceable chip-type recording head that can be electrically connected to the apparatus main body or supplied with ink from the apparatus main body by being attached to the apparatus main body, or is provided integrally with the recording head itself. The above-described embodiment is also effective when a cartridge type recording head is used.

It is preferable to add recovery means for the recording head, preliminary auxiliary means, and the like as the configuration of the recording apparatus of the above-described embodiment because the effects of the above-described embodiment can be further stabilized. If these are specifically mentioned, a capping means, a cleaning means,
Pressurizing or suctioning means, electrothermal transducer or another heating element, or preheating means using a combination of these means, and preparatory ejection mode in which ejection is performed separately from recording can be performed stably. It is effective to do.

Further, the recording mode of the recording apparatus is not limited to a recording mode of only a mainstream color such as black, but may be a recording head integrally formed or a combination of a plurality of recording heads. The above-described embodiment is also very effective for an apparatus provided with at least one of full colors by color mixture.

In the above-described embodiment of the ink jet recording apparatus, the ink is described as a liquid. However, for example, an ink that solidifies at room temperature or lower and softens or becomes liquid at a temperature higher than room temperature. Is also good. Alternatively, in the above-described ink jet, the ink itself is heated to 30 ° C.
Generally, the temperature is adjusted within a range of not more than ° C. and the temperature is controlled so that the viscosity of the ink is in a stable ejection range. Therefore, it is sufficient if the ink is in a liquid state when a recording signal is applied.

In addition, whether the ink is used as energy for changing the state of the ink from the solid state to the liquid state to prevent temperature rise due to thermal energy, or use ink that solidifies in a standing state for the purpose of preventing evaporation of the ink In any case, the ink is liquefied by application of the thermal energy according to the recording signal, and is discharged as an ink liquid,
The use of ink having a property of being liquefied only by thermal energy, such as one that already starts to solidify when it reaches the recording medium, is also applicable to this embodiment. In such a case, the ink can be used in JP-A-54-56847 or JP-A-60-56847.
As described in -71260, while held as a liquid or solid in a porous sheet recess or through hole,
It is good also as a form which opposes an electrothermal transducer. In the above-described embodiment, the most effective one for each of the above-mentioned inks is to execute the above-mentioned film boiling method.
