Abstract

PURPOSE:To eliminate sag to be generated on an ink film and avoid missing in transfer, by a method wherein the pressing of a thermal head, an ink film and a recording paper is released when the thermal head is not operated. CONSTITUTION:In a recording stand-by condition wherein the recording paper 22 and the ink film 33 are set in position, no electric current is supplied to an electromagnet 51a, and the thermal head 20 and a platen roller 72 are in a presse- contacting condition. After passing an electric current to the electromagnet 51a for a predetermined period of time and after a period T1 of time required for actually releasing the presse-contacting condition is passed, the ink film 33 is traveled by a predetermined distance. Accordingly, a tension is applied to the film 33, resulting in that wrinkles which have been present are stretched out. Then, the supply of electric current to the electromagnet 51a is stopped, the thermal head 20 and the roller 72 are again pressed to contact with each other, and recording is conducted by traveling the head 20 and the roller 72 at the same speed in the close contact condition.

Description

[Detailed Description of the Invention] <Technical Field of the Invention> The present invention relates to a thermal transfer recording device. They are increasingly being installed in general offices as part of office machinery. Among these recording devices, those with a thermal transfer layer have the advantages of a simple mechanism and good tamper resistance and storage stability. There are two types of thermal transfer recording apparatuses; one is a serial type in which recording is performed while the recording head scans horizontally with the ink ribbon for each line; The other type is a line printer that records using a thermal head with heating resistors lined up across the entire recording width. In either case, an ink film as a carrier is electrically connected to paper, and a thermal head is pressed onto the paper to selectively transfer the ink to the recording paper for recording.

In a device that performs 2- for thermal transfer, improve the layering properties between the thermal head, ink film, and recording paper on top of the raw salt, reduce thermal resistance, and make it easier to transfer ink from the ink film to the recording paper. This is very important. In order to improve the adhesion, the film is thin and has a tendency to stick to the mouth.

On the other hand, since the ink film is thin, if t, m<, 7w occurs, the ink film and the recording paper will not come into close contact with each other in some areas, and the ink will not transfer properly in those areas. This is so-called transfer missing, and this is one of the major causes of recording defects. In the case of the /real type, the width of the ink film is as narrow as a few points, and the /wa is originally born, +C<<, and since the width of the C is narrow, the 7/wa easily escapes at both ends. . In the Nyi/Puri/Me type, 201 Yang Du's 111! ink was inked on an extremely thin base film of 10 μm thickness. I am using an ink film with For this reason, wrinkles tend to occur due to the tension between the area where the ink is transferred to the recording paper and the area where the ink remains due to recording, and the film base expands and contracts due to heat. 1-11 The wrinkles that have occurred are difficult to escape to the edges.
When wrinkles occur, they grow larger as more records are collected, and eventually the wrinkles start to disappear.

In this way, recording devices that use thermal transfer have problems such as missing transfer due to wrinkles in the ink film. Even in serial type devices, ink film is used to increase printing speed + W + law. This problem may occur if you make it thinner or wider.

<Object of the invention> The present invention has been made based on the above circumstances!
1, it is an object of the present invention to provide a thermal transfer recording device which has a relatively simple configuration and can be used reliably for recording.

<Summary of the Invention> For the above-mentioned purpose, the present invention brings the thermal head into pressure contact with the ink carrier (ink film) and the recording medium (recording, It) at a point in time when the thermal head is not operating, that is, at 1
Solve at the position corresponding to the true front and rear or line space position. Next, by the force of empty feeding of the ink film, a new film is placed opposite the length of the ink film, and the slack in the ink film is removed. As a result, the wrinkles that had occurred are prevented from continuing, and the wrinkles are smoothed out by the tension of the ink film. (-) is a schematic diagram illustrating the basic configuration of the thermal transfer device according to the present invention. The film base 111il is pushed by the thermal head 4, and the ink film that presses against the recording paper 4, which is the C1-related medium, is taken up from the supply field/kufilm winding shaft (34a) to the winding head/kufilm winding shaft (34b). ). The Q paper @ fed out from the recording paper roller (71) is pressed against the platen roller (72) by the pressing force of the thermal head. The frictional forces between the thermal head ■ and the ink film (to), the ink film (to) and the recording paper @, and the recording paper (2) and the platen roller (72) are set to be large according to this request, and the motor ( The ink film and the recording paper are fed at the circumferential speed of a platen roller (72) driven by a platen roller (74). Thermal head 4 and platen roller (72

The recording paper C4 and the ink film (1) may be supplied using a roll (34c) wrapped around the fins as shown in Figure 1(b). good.

An embodiment of the heat transfer #1 #ct having such a basic configuration will be described with reference to FIGS. 2 to 10. As shown in Figure 2 (a), which depicts the overall configuration of the device, this embodiment actually depicts a great feature! IA spear club Oυ and this S
It consists of an electric control section a that controls the bridge section αυ and exchanges information with the outside, and extracts all image information from an external information processing device or 1m image stacking device, and transfers this to recording paper as a recording medium. It is something that is drawn in.

In the mechanical section 00 of this thermal transfer apparatus, as shown in FIG. 2(b), the ink film (not shown) is a metal box. The upper lid part (2I) and the bottom part (to) are always connected via a bearing on the back side, assuming that the side from which the recording paper is fed is the front side.4.The side surface VC on the front side of the upper fE part Qv is Lock knock (24a), (24

When it is fixed, the heat generating resistor of the nine-square head 4 provided in the top portion 3υ is brought into pressure contact with the recording paper C2.

The ink film (not shown) can be installed without wrinkles by removing the locking hooks (24a) and (24b) and raising the E lid part Qυ, as will be described later.

Each part will be explained in more detail. As shown in Figure 3, the upper lid part ■υ includes a ψ-maru head (end) that includes a heating resistor (end), a drive system (end) that moves this thermal head (end) up and down, and an ink film (end). ), - Ink film winding shaft (34a), (34b), Travel guide, -

Of these, the thermal head (to) and the ink ribbon are movable.

The thermal head 4 is made of ceramic gray including a heating resistor CA as shown in FIG.
This ceramic plate is held by a metal plate (43).

A terminal for supplying operating power (441, Mizuko +a'j for Gundo, and a terminal for supplying various signals to the IC package (c) is provided.The black signal supplied to the IC package (l) is - image signal, clock pulse,
This is an enable signal and a launch signal. Heat generating resistor (2)
One line is provided with an fI concentration of about 21,518 to 12 g/fl. In this embodiment, the i-6B lt is capable of recording 4-size wax paper. #II construction E, this heating resistor (4) is tilted to one end of the ceramic plate I. In this example, the heating resistor (4) is tilted to the side where the recording paper (z4 is fed out).For convenience of explanation, The heating resistor (to) 21, where the heating resistor (to) is located, is called the # side, the IC package (c), etc. are commercially available.

The plate I is made of aluminum, and on the opposite side to the side on which the heating resistor and the like are provided, unevenness is provided to improve the heat dissipation effect. Also, there is a protrusion (48a) on the front side of the @ country of the metal plate.
48b) is in the rear, and supporting metal fittings (49a) and (49b), which are the center of rotation of the metal plate, are provided symmetrically. Support metal fittings (49a), (49b

It seems to be sandwiching.

As shown in Figure JG3, the levers (50a) and (50c) are played on the skin that is not in contact with the protrusions (48a) and (48b). (51b) is mechanically connected to the plates (51m), (51b) only when energized, as shown by the arrow (53), against the plates (52a), (52b). A force directed backwards from the cutting is generated by 4. This force is caused by the L-shaped shapes of the shafts (54a), (54b) and levers (50a), (50c), causing an upward force to be exerted on the protrusions (48a), (48b). ftE

ky-f (19,6N).

The protrusions (48a) and (48b) are connected to the metal plate 14.
Since the 4VC is integrated, the above-mentioned force (t) rotates the thermal head (2) - Therefore, a downward force is always applied to the thermal head (a), and the electromagnet is energized. As described above, an upward force λ is applied only during non-recording. In this embodiment, the thermal transfer printer performs recording while keeping the heating resistor (1), the ink film (4), and the recording paper 4 in pressure contact. When applying pressure from the heating resistor (to)-11 to t# to achieve the pressure M between the ink 7/ilm (to) and the recording paper, the line of action of the force on the thermal head (to) is , heating resistor (E), the printed part on 114, and the platen roller (72) to be described later.
) is consistent with the origin that connects the center of Therefore, the line of action of the force and the direction of heat transfer from the heating resistor (to) to the ink film (to) and the recording paper Q4 do not match, and as a result, the ink transfer is not accurate. , ka-
Stability 1 is performed. Further, since the point of application of force and the fulcrum are sufficiently long, rotation of the thermal head (a) can be performed efficiently with minimum force. When not recording, electromagnetic warp (51a)
, (51b) is energized, and the thermal head ln
A force is generated in the direction of KUE, and the pressurized state of contact between the letter and the recording paper 24 is released. Therefore, the ink film a and the recording paper sheet 4 can freely run relative to each other.

In front of the range plate-4, there is an arm # as shown in Figure 3.
(56), and a vi/tir roller (57) (omitted in FIGS. 2 and 4(a)) is attached to it.

As will be described later, after the transfer, the VC is not immediately peeled off from the recording paper sheet 4 and the ink film, but the ink is allowed to run for a while until the VB layer +Etaf is removed. Uniform transfer sharpness and uniform shrine &
1-[4)U Next, we will explain the ink film running drive system.It should be noted here that the ink film as an ink carrier (I is very small) In addition, since the width is wide, the problem of point 1 (V), where wrinkles are likely to occur, is that in this invention, if wrinkles occur between the ink film, transfer gaps will occur and become a problem. The following configuration is used for rounding to eliminate this. The driving force of this drive system is the rotational force of the pulse motor (77), as shown in FIG. 4(b). This rotational force is applied to the ink film winding shaft (34) via the toothed belt (12i).
b) The transmission is transmitted to (122). The sprocket (122) has a cylindrical @kaku,
A minus sign is provided on this same surface and meshes with the toothed belt (121). The sprocket (122) is integrally provided with a shaft (123) passing through its center. This shaft D23) Fi, bearing (124a), (lJ4

The rotation speed of the motor (77) is kept constant t(
If this is done, the transport speed of the ink film will not be constant. In this embodiment, in order to prevent this, the ink film winding core (1

t - sandwiched from both sides.

The rotational force of the support (123) is transmitted to the pressure adjustment piece (126L). This rotational force is transmitted to the tail presser (129L) t1c via the spring (128L). At this time,
Since there is a spring (128L), a force of 1 is generated in response to the rotational force of the shaft (12, ()), and the tail presser (129L) makes 9 rotations according to the six lids ('l1j1) of the ink film (to). As a result, as the amount of ink film to be wound increases, the number of revolutions at the ink film winding core (125) decreases.Conversely, the radius of the ink film roll increases, so the conveyance speed of the ink film increases. becomes constant.

At the same time, the spring (128L) and (xzsR) are
The ink film winding core (125) is pushed from the opposite direction (two joints, core holders (129L), (129R)) to transmit round rolling force to the ink film roll.

On the other hand, the ink film winding shaft (34M) is the side that supplies the ink film, and its structure is almost the same as that of the ink film winding shaft (34b). However, sprockets)
(122) is replaced by a rotation stop (130).

By doing this, the ink film is constantly conveyed at a constant speed and a constant tension is applied, so that wrinkles occur.

As shown in No. 3-, a roll of recording paper (71)
The platen roller (72) and platen roller (72) gives running force to the recording paper (2) that is rolled out from the rolled paper (71) and transfers the ink to the outside. In order to reliably transmit the feeding force from the platen roller (72) to the recording paper-4,

The difference is that the SCM tie-in/g (stb) and the timing of independent ink film feeding are different, and are carried out even in the middle of one night's recording. Therefore, the incident-

In the M-shaped layer, the electromagnets (51M) and (51b) are not energized, and the thermal head (to) and platen roller (72) are not energized.
This is in pressure-welded embroidery. When writing on the first page from this foreshadowing, first, the voltages 6 (51a) and (5xb) are energized to release the pressure contact, and after a time Tljl, the pulse motor (77) is driven and the ink film is The electromagnet (5ia), (51b)

A driving pulse is supplied to a pulse motor (74) to a pulse motor (74) and a pulse motor (77) to run the recording paper (2) and the ink film 81 in close contact with each other in the same direction and at the same speed. Next, as the recording progresses, the wrinkles increase and before the extreme wrinkles that cause transfer gaps increase, the 1011th
As shown in i1(a), temporarily interrupt the output signal and at the same time stop supplying drive pulses to the pulse motors (74) and (77).

), and if (for example, a normal) r comb, it is 7.821'l■, so the opening point is 2111 or more, and the 12 lines to be assembled by the machine at 1.5■ are the predetermined number of white lines. ) When the predetermined number of fins is 4, the number of t comparators (100) and comparator (

This is achieved by stopping the internal pulse motors (74) and (77). Due to the characteristics of the pulse motor, if the drive pulse is not supplied, it will be locked at the stop position, so the recording paper
It can be stopped with an accuracy of 0.00 fim or less, and no discrepancies occur between recording and images due to positional deviation when restarting. Next, as shown in @tolil(b), the noble electromagnet (5ia) e (51b) is energized, and the thermal head (2) and platen roller (72)
(7) As shown in Figure 1(d), run the ink film for a distance of 21gl.
By doing this, even if the wrinkles accumulated and increased due to the recording operation up to that point are removed,
After solving this problem, we press the thermal head... and Noraden Ichira (72) again to continue the recording operation, completing the recording of one component. Of course, you may do this as many times as you like to smooth out the wrinkles that occur during the operation of the brass.

According to another modified example, even when the true recording length is long, a line m for smoothing out wrinkles is inserted in the middle of recording to prevent wrinkles from increasing and to prevent transfer defects due to wrinkles. You can save by keeping the quality control stable.

<The effects of the invention are described in detail above! In addition, according to the present invention, each time or during the process of unloading, it is possible to smooth out the wrinkles that occur in the case, and also to remove the wrinkles that occur in the case, and to send the wrinkles up to the 4 [7th place]. It is possible to provide a thermal transfer recording device that can prevent the increase of wrinkles, prevent the occurrence of recording defects due to transfer gaps, and always maintain stable recording quality.

Although the present invention has been described above, the present invention is not limited to the above-mentioned embodiments, modifications thereof, and modifications of the pond. For example, a pulse motor may be used to feed the ink film of the recording paper, and other motors may be used instead, and it is of course possible to limit the pressure contact by driving in the cam direction or in the opposite direction. Further, the recording paper may be sheet paper.
