Abstract

PURPOSE:To shorten a time required for recording one piece of card without providing a special mechanism on control, by a method wherein a movable carriage carrying a card thereon is allowed to move back and forth while recording is conducted on the card and a color-ink film is continuously fed in a fixed direction. CONSTITUTION:A color-ink film 22 is so placed that the head of Y-color thereof is set right under the heating resistor array of a thermal head 20. A movable carriage 27 starts travelling in the direction (d); simultaneously the film 22 starts running in the direction (f) at the same speed as that of the carriage 27, and the thermal head 20 transfers signals for recording the Y-color component sent sequentially from memory to start the Y-color recording at the leading edge of a card 26. Upon completion of the Y-color recording, the M-color (and BK-color) signals are transferred in the exact reverse read-order to that for the Y-color signals; simultaneously the movable carridge 27 starts travelling in the direction (e), and the film 22 starts running in the direction (f). At this time, the head of the M-color of the film 22 has been brought to right under the heating resistor array. With the M (or BK) color recording, image signals stored in memory are recorded in the order reverse to that of the Y (or C) color recording, starting at the last scanning line.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a recording device that prints an arbitrary color image on the surface of each mallet card, sometimes recording using a thermal transfer recording method. @ [Prior Art] Fig. 4 is a diagram showing this conventional plum recording device.

FIG. 5 is a block diagram of a color ink film used in the recording apparatus shown in FIG. 4.

Next, the operation 'f of FIG. 4 will be explained with reference to FIG.

Press the 1ft button (not shown) to start copying, and turn on the light source 3. The reading system consisting of the #A original 7 lens 4 and the reading sensor 5 starts moving to the right, sequentially reads the color information of the color original 1 on the transparent glass 2, and stores it in the image memory 6. To read color information, use light source 3 (R (red), G peak)
, B (reflected light is read by the next reading sensor 5 by sequentially emitting yf?i elements at intervals consistent with the three primary colors). The reading sensor 5 is a CCD sensor normally used for reading facsimiles.

That is, the information obtained by shining the R light on the color original 1 and converting the intensity of the reflected light into an electrical signal is the information obtained from the color original 1.
The reflected light for G light is C information, and the reflected light for B light is B information. Therefore, R
, G, and H are sequentially emitted to scan the entire color original 1 and read the reflected light.
4! Read the color information that is displayed.

The information from the reading sensor 5 is sequentially accumulated in the image memory 6, and the accumulated information is then sent to the image processing section 1.
G, B information is recorded in 3g, color cyan (C), (yellow (
Y), magenta (M), and then black (BK) and stored in the image memory 8.

Both 6 and 8 are image memories, or 6 is a buffer memory for matching the operating speed of the image processing section 7 and the reading speed of the reading sensor 5.

Of the color information C, M, Y, and BK for 101 color originals stored in the image memory 8, the C information is first sent to the thermal head drive circuit 10 of the recording section to start recording.

When recording is started, the color ink film 1) wound around the color ink film roll 12 is taken up by the take-up roll 13, moves toward the recording medium 14 fixed to the moving base 15 in the direction of the arrow According to the information, the cyan ink heated by the thermal head 9 is melted and adhered to the recording medium 14, and recording with the cyan ink is performed. When the C information has been recorded on the entire surface of the recording medium 14,
The state is shown by the dotted line in the figure.

Subsequently, the movable table 15 moves in the direction of the arrow {circle around (2)}, returns to the position shown in FIG. 4, and once moves up. At this point, in order to record the next M information, the color ink film 1) is rolled onto the take-up roll 13 so that the magenta part is below the thermal head 9.
operation is controlled.

The control method is to use the position detection mark shown in FIG. In other words, the home position detection mark I
A mark 18 for detecting a recording start position is provided.

The two oval types of position detection marks are for detecting the home position of the color ink film 1) and for color detection. In other words, two consecutive position detection marks are placed every third position, but the sensor 16 detects two consecutive position detection marks.
The position where these marks are detected simultaneously is the home position and the cyan recording start position.

The next 3IlvA mark starts recording magenta, yellow, and black in this order. After recording magenta information, a total of four colors, including yellow G7+ and black, are recorded in order to complete recording of one sheet. The conventional recording device is as described above.

[Problem that the invention seeks to solve]

Now, focusing on the recording section, the movable table 15 is returned one color at a time, positioned at the home position, and -1ie
It is stopped. Further, the take-up roll 13 must be operated so that the leading edge of the next color to be recorded on the color ink film 1) is positioned below the thermal head 9. Therefore, 1
The time required to finish recording one sheet is simply the recording time per color x the number of colors (4) x the moving table return time plus the film set time, which is extremely long (and the color ink film 1). It has disadvantages such as the need for various and many marks for the control for setting.

The purpose of this invention is to solve the above-mentioned problem that it takes a long time to record one card, and to provide a card-like recording device that can record without the need for a gender-neutral Isosu and number control system. do.

[Means for solving problems]

means, a color ink film coated with ink necessary for multi-color color recording, means for running this color ink film only in one direction, and movement of the movable base during the forward and return trips of the movable base. It consists of means for recording in correspondence with the information.

[Effect]

In this invention, the color ink film travels in one direction, and recording is performed both when the movable stage is traveling forward and when it is traveling back.

FIG. 2 shows a structural diagram of the color ink film 22 used. The running direction of the color ink film 22 (Y, M, C from the beginning of ψ million times in FIG. 1).

BK and Men] It has been covered with ridges, and I will record it with this song. Moxibustion level 1 from the first position of Y color to the position mark
．． is made equal to the distance traveled by the color ink film 220 from the heating resistor array to the sensor 31 in FIG. The coating width d of each color is determined by the length of the card 26 or the predetermined recording length g (not shown).

Also, the moving speed υ of the moving table 27. and the running speed ν of the color ink film 22 are ve=ν.

Furthermore, the operation of the step motor 28 is synchronized with or corresponds to the recording of the thermal hand 20. That is, the number of steps P of the step motor 28 is the total number of recording runs L=j
l (j is the number of scanning lines per unit length) is equal to VC. However, taking into account the number of steps NY per run fd, P=NjJ.

FIG. 3 is an explanation section of the operation.

The next ic@ construction will be explained with reference to Fig. 1, Fig. 1i42, and Fig. 3.

First, the top of the Y color of the color ink film 22 (the second one,
The third factor (a)) is located. This uses position mark 3B in FIG. ? The step motor 2B is rotated by the ff1J control circuit 32vc, and the moving table 27
starts moving in the direction of ■ in the figure.

At the same time, the color ink film 22 also starts running in the direction of 1 at the same speed as the moving table 27 due to the operation of the motor 24. -! Synchronized with the rated motion base 27, the industrial heat hand 20
The recording signal of the Y-hull component is sequentially transferred from the memory 34 to start the recording operation, and recording of Y color is performed from the leading edge of the card 2B (FIG. 3(b)).

The above operation is continuously performed until the entire surface of the card 26 fixed on the moving table 27 or a predetermined recording length is completed.

When the Y color recording is completed, that is, the Y color signal in the memory 34 becomes 0 (L=0), the control circuit 32 transfers the next M color signal. The movable table 27° card 26 is at a position fvt indicated by the dotted line in the middle of the first factor.

In order to display the screen, the M color signal and the BK number are read out in the exact opposite order to the reading order of the Y color 1M number.

At the same time, the step mode 2B is reversed so that the moving table 21 moves in the direction (in the figure).

At this time, the leading part of the M color of the color ink film 22 is located directly under the heating resistor 7 lay 21, and continuously
F] Run all the time. Therefore, in this state, card 26
(Figure 3 (c))
. The memory/source of M color (and BK) is stored in memory 3 like this.
In contrast to the image signals stored in the memory 34, the Y color (and the C color) are recorded starting from the last running line. Go.

The image signal of the M8 component is transferred from the memory 34 and recorded by the thermal head 20 on the Y color of the card 26 of the moving platform 210 (FIG. 3(d)).

M color < g is 0, that is, the rear shoulder of the card 26 on the moving table 27 reaches just below the heating resistor array 21 (
1 point), the recording of Y color starts, and the memory 34t-0 color-gI reading field is switched, and the step motor 28 is reversed so as to move 827YYB2 to 10,000 times. .

The leading edge of color 0 of the color ink film 22 is positioned directly below the heating resistor array 21, and is continuously run.

Now do IK and record up to BK color, and one color recorded image will be VC recorded on 26 sides of the card. At this time, it becomes the initial position (Fig. 3(a), 'e)).

Here, the load on the step motor 28, ie.

Mobile platform 27. Color ink film 22. If positioning is difficult due to friction or negative inertia in the transmission system, etc., use the moving platform 27.
The start and stop positions are J, , Jl in Figure 1.
l, and considering this interval, −Cfi
All you have to do is measure it. However, in this case, the time increases by this amount. In addition, the application width d of each color of the color ink film 22 and the interval 'lt between the position marks 3B and the moving stage 27
c! 'r - Time appropriate for switching the rotational direction of the step motor 28? Taking into consideration, the coating width d of each color of the color ink film 22 is slightly
It is also necessary to be a leader.

1) While the moving table 21 moves on the outward and return journeys, the color ink film 22 travels a certain number of times, so the constant force on the contact surface between the color ink film 22 and the card 26 changes. The driving force of the motor 24 may be made higher than the friction force when the color ink film 22 and the moving stage 21 move in opposite directions. Further, the bank tension of the color ink film 22 may be set based on the same idea.

Furthermore, in recent years, there has been a color ink film 22a that allows the same portion to be used repeatedly for recording. When using this color ink film 22a, if the number of times that can be repeated is 1Ii18, then the moving table 27, that is, the card 2
6 movement speed υ. The running speed υ of the color ink film 22a that can be repeatedly recorded.

is tlf ``ν/n, and the traveling speed v in degrees Celsius can be determined accordingly.For example, when using the reusable color ink film 22a'ft with n = 2, the moving speed UvaK of the card 26 is traveling speed v
Just run it at 1. In this case, the coating of each color of the reusable glass ink film 22 & = d
If the distance between the position marks 38 and the distance between the position marks 38 and the position marks 38 is changed accordingly, the device of this invention [[VC
Can be used.

In this way, the color ink film 22 and the card 26f
or the traveling speed of the moving table 27 is υ', υ.The ink cloth width d of each color of the color ink film 22 is Il
When f”El, the effective recording length C6 of the card 26 or the moving distance of the moving base 27 @IVc is equal, and a color ink film 22 m that can be repeatedly recorded many times is used.
When carried out under the condition of υ, <v, + a = 1. Il)/
n, (t, = r L, vl = ve/n).

Note that the width d of each color ink applied to the color ink film 22 when a slight stop time l is set when switching the reciprocating motion of the moving table 27 or when one stone is applied is d=J.

= l (vl = v.), d
= J, (J>/n (7 Miko r L,
When vt = hA, the color ink film 22 is stopped for the same length of time as the moving base 21 is stopped. If it is not stopped, increase the damage of each color's ink for 7 hours @color, and 1 ink is better. At this time, the ink application process for each color is d + Δd, and Δd=v, Ht (t=
(stopping time of the S moving table 21).

Furthermore, when using vf>vc, the ink cloth width of each color d J 't d : v2 /

A similar configuration may be used when the moving platform 27 is stopped due to heat.

Also, the position mark 38 of the color ink film 22
and positioning a! of the sensor 31 for reading marks! By taking into account the differences in the ink droplets of each color and the errors in the time of ink dropout, and stopping and positioning the VC moving table 27 and color ink film 22 for each color, a more accurate record can be achieved. can be done.

It is needless to say that the above-mentioned card 26 only needs to be similar to a card.

〔Effect of the invention〕

As explained above, this invention allows a moving table to be loaded with a card to reciprocate, perform recording on both outbound and return trips,
And color ink film continuously at a constant rate of 10,000 @! @ I made it work, so record-1 F9r for Maki Atsushi
*There is an advantage that the time is shortened and that the cent control of the color ink film and the complication of the mechanism for this can be avoided.
