Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a recording apparatus that performs recording by heating a rotating transfer medium.

<Prior Art> The thermal recording method has been widely used in recent years because of its general features such as a small and lightweight device and no noise, as well as the ability to record on plain paper.

Conventionally, a generally used thermal recording device forms a transfer medium by coating a heat-resistant base film with a thin layer of heat-melting ink, superimposes the ink layer of the transfer medium on the recording medium, and prints the image. A recording head that generates heat according to information heats the base film side, melts the ink on the transfer medium according to the image bounce, and transfers and records it onto the recording medium (Japanese Patent Laid-Open No. 58-220795).
.

<Problems to be Solved by the Invention> However, in the conventional heat-sensitive recording device described above, the heat-melting ink must be coated on a relatively expensive heat-resistant base film through a complicated process, and furthermore, this Since the transfer medium is disposable once transferred, the running cost is high (and the heat-melting ink must be heated through the base film, so there are problems such as poor thermal efficiency).

In addition, in order to improve thermal efficiency, there is a method in which the heat-resistant base film is made of a conductive film, and the recording head is made up of electrodes that are energized according to the image information, and the ink is directly heated by Joule heat. Kaisho 58-12
No. 790), this configuration makes the base film even more expensive.

The present invention solves the above-mentioned conventional problems and provides a recording device that can reduce running costs, has good thermal efficiency, and can effectively smooth the surface of a transfer medium after transfer recording. .

<Means for Solving the Problems> Means of the present invention for solving the above conventional problems includes a rotatable transfer medium, a recording head that heats the transfer medium according to image information, and a surface of the transfer medium. The transfer medium is characterized by being provided with a smoothing member for smoothing the surface of the transfer medium, and a concave-convex member having minute irregularities on its surface and rotating in pressure contact with the surface of the transfer medium.

<Operation> According to the above means, the transfer medium rotates in accordance with recording and is heated in an image pattern by the recording head, and the heated transfer medium is transferred onto the conveyed recording medium.

In addition, since the uneven member rotates in pressure contact with the transfer medium after transfer recording, the surface of the transfer medium becomes a finely uneven surface, and by smoothing the fine uneven surface with a smoothing member, the entire surface of the transfer medium is uniformly smoothed. It is something that

It is configured as follows. Further, knurls 3b are provided at both ends in the longitudinal direction of the pressure roller 3, and when the pressure roller 3 is driven and rotated as described above, the knurls 3b bite into the ink roller l, causing the ink roller 1 to rotate in a driven manner. It consists of

Furthermore, as shown in FIG. 3, a gear 1b is attached to one longitudinal end of the ink roller l, and a gear 2C is attached to the side plate 2. The gear 2C attached to this side plate 2 is attached above the gear lb at a slight distance, and the ink roller 1 is moved upward and downward along the vertically elongated hole 2a.
The gears lb and 2c are configured to mesh with each other when the ink roller 1b and 2c slide toward each other, and rotational force is transmitted to the ink roller l by the motor 2d connected to the gear 2C at this time.

Next, to explain the recording throat 5, Fig. 4 (A)
As shown in (B), the recording head 5, which has approximately the same length in the longitudinal direction as the ink roller l and has a heating element (not shown) that generates heat according to image information, is attached to the support by a screw 15a. It is attached to 15.

Guide protrusions 15b are provided protruding from the upper portions of both sides of the support body 15, and a U-shaped notch 15c is provided at the lower end. When the support body 15 is urged in the direction of arrow r by the eccentric cam 17 which is attached to the support side plate 16 by being locked to the support protrusion 16b and rotated by a motor (not shown), the guide protrusion 15b is rotated about the support protrusion 16b as a fulcrum. It is configured to slide along the curved long hole 16a. Further, 18 indicates the guide protrusion 15b and the supporting side Fi1.
6, the spring is stretched between the guide protrusions 15
b is pulled in the -f direction (the minus sign indicates the opposite direction to the arrow).

Here, as shown in FIG. 4(C), the curved elongated hole 16a is formed at the contact portion d when the guide protrusion 15b slides using the support protrusion 16b as a fulcrum as the diameter of the ink roller decreases.
It is configured in a curved shape to guide the slide of the guide protrusion 15b so that the angle between the circumferential length of the ink roller 1 from the to the pressure contact part C and the normal line at the contact part d and the recording pad 5 is always constant. has been done.

Further, a nut member 16C is non-rotatably attached to the outside of both supporting side plates 16, and the nut member 16C is threadedly engaged with a lead screw member 19. As shown in FIG. 1, this lead screw member 19 is a U-shaped holding member 19 that is attached to a predetermined position of the side plate 2 with screws 19a.
b is rotatably held, and a boot 9C is fixed to the end of each lead screw member 19,
A bell) 19d is suspended between each boot 9C. Furthermore, a gear 19e is attached to the end of one of the lead screw parts +4' 19, and the drive of the motor 19r connected to the gear 19e rotates the lead screw member 19, and accordingly the NAND member 16C slides along the lead screw member 19, and the recording head 5 slides in a direction perpendicular to the axial direction of the ink roller 1.

Next, the smooth blade 6 is formed to have approximately the same length as the length in the axial direction of the ink roller 1, and as shown in FIG. It has a knife-like structure that can be cut with. Two slide protrusions 6a are protruded from both ends of the smooth blade 6, and the slide protrusions 6a are slidably inserted into guide holes 2b drilled in the side plate 2, and furthermore, the ends of the protrusions 6a As shown in Fig. 1, there is a slide plate 6.
b is attached to the slide portion 6C formed on the side plate 2.
It is configured so that it can be slid along.

Further, a locking protrusion 6d is provided protrudingly on the slide plate 6b,
The projection 6C is in contact with one end 20a of the link member 20. The link member 20 is composed of a member bent in a J-shape, and is rotatably attached to the side plate 2 by a link shaft 20b at the bent part, and the other @20C is connected to the rotating plate 1.
It is configured so as to come into contact with the lower end of 3. Therefore, when the diameter of the ink roller 1 decreases and the rotary plate 13 rotates in the direction of the arrow g, the link member 20 rotates in the direction of the arrow G to slide the smooth blade 6 along the guide hole 2a.

Further, an eccentric cam 21 is attached to the lower part of the link member 20 so as to be in contact therewith. This eccentric cam 21 is connected to the rotating plate 1
The rotating shaft 21a of the eccentric cam 21 is rotatably attached to the side plate 2 at a position below the link member 20 that contacts the link member 3.
and motor 21b are connected via one-way clutch 21c, and only when motor 21b rotates in the direction of arrow i, one-way clutch 21c is locked and rotates eccentric cam 21, whereby link member 2
0 is configured to rotate in the direction of arrow -h.

Next, as shown in FIG. 5, the uneven member 24 is composed of an uneven roller having approximately the same length in the longitudinal direction of the ink roller 1, and a mesh-like minute unevenness is formed on the surface of the roller 24. ing. This mesh varies depending on the thickness of the ink transferred during recording, but the amount of ink transferred is 2.
If the mesh size is 6 .mu.m, the pinch of the mesh is 2 .mu.m or more, and the depth is about 1 .mu.m or more.

Further, a shaft 24a protruding from both ends of the uneven member 24 is rotatably inserted into a long hole 2e formed in the side plate 2, and the shaft 24a is further pulled toward the ink roller 1 by a spring 2r. Therefore, the inverted crown-shaped uneven member 24 is always in pressure contact with the surface of the ink roller 1, and is configured to rotate following the rotation of the ink roller 1. The pressing force is 500 g/cm to 1 kg/c
It is recommended to set it to about m.

As shown in FIGS. 1 and 2, the sheet 1 feeding means 7 has a feeding roller 10 and a timing roller 11 having a length longer than the axis of the recording sheet 8, and has rollers 10 and 11 at both ends thereof. The shafts 10a, lla are provided protrudingly, and the shafts 10a, lla are provided protrudingly.
a is pivotally attached to the side plate 2 and is configured to be rotatable by a motor 4 that rotates the pressure roller 3.

The feeding roller 10 is installed at a position where it comes into pressure contact with the top layer of recording sheets 8 stored in the cassette 9 when the cassette 9 is loaded into the apparatus, and moves in the direction of arrow j according to the recording operation. It is configured to rotate and separate and feed the recording sheets 8 one by one.

Further, the timing roller 11 rotates in the direction of the arrow in synchronization with the rotation of the pressure roller 3 that operates according to recording, and conveys the recording sheet 8 between the ink roller 1 and the pressure roller 3, and is made of stainless steel or It is composed of a pair of rollers in which metal rollers such as iron are arranged above and below, and a tension spring 22 is attached between the mutual shafts lla,
The pair of rollers is configured to come into pressure contact with each other. The pressing force between the pair of rollers by the tension spring 22 is set to be at least 16 kg/cIm'', which is a general fixing pressure when an image transferred in a copying machine or the like is fixed under pressure.

Further, a sheet guide 23 for guiding the recording sheet 8 being conveyed is provided between the feeding roller 10 and the timing row 911 and between the timing roller If and the pressure roller 3.

Next, the operation of the above-described well-constructed device will be explained.

When the motor 4 is driven, the pressure roller 3 rotates in the direction of the arrow a, and the ink roller l rotates in the direction of the arrow. At the same time as this rotation, the recording head 5 generates heat according to the image information, heats and melts the ink on the surface of the ink roller l in an image pattern, and the ink remains in a molten state as the ink roller l rotates. This leads to C. At the same time, the supply roller lO and the timing roller 11 rotate in the directions of arrows j, respectively, to transfer the recording sheet 8 to the cassette 9.
The sheets are separated one by one from the inside and conveyed to the pressure contact section C in synchronization with the recording operation. Therefore, the molten ink in the form of an image pattern is transferred to the recording sheet 8 at the pressure contact portion C.
A recording sheet 8 on which a predetermined image has been recorded is discharged to a sheet receiver 12 by rotation of an ink roller 1 and a pressure roller 3.

Further, after the ink has been transferred, the surface of the ink roller remains partially uneven because the transferred ink escapes. Thereafter, the ink roller l comes into pressure contact with the uneven member 24, and due to this pressure contact, minute unevenness corresponding to the network-like unevenness of the uneven member 24 is formed on the entire surface of the ink roller 1, and then the surface of the roller l is heated by the smooth blade 6. It is cut or heat-smoothed to eliminate the minute irregularities and become a smooth surface.

In the above process, when the surface of the ink roller 1 is smoothed by the smoothing blade 6, if minute irregularities are formed over the entire surface of the roller 1, the smoothing blade 6
The smoothing effect is significantly enhanced and smoothing becomes easier.

The diameter of the ink roller 1 decreases as recording progresses due to ink transfer and cutting by the smooth blade 6, but the core la of the ink roller 1 slides along the vertical hole 2a as the roller diameter decreases. Therefore, the ink roller 1 and the pressure roller 3 are pressed against each other with a constant pressure regardless of the change in the roller diameter.

Since the uneven member 24 is similarly pulled toward the ink roller 1 by the spring 2f, the shaft 24a slides along the elongated hole 2e when the ink roller diameter decreases.

Therefore, the uneven member 24 is always pressed against the surface of the ink roller 1 with a constant pressure.

Further, the sliding of the core 1a causes the rotating plate 13 to rotate in the direction of the arrow g, and accordingly, the link member 20, in which the lower end and one end 20c of the rotating plate 13 are in contact, rotates in the direction of the arrow. Then, the locking protrusion 6c is pressed and the temporary slide 6
b and the slide protrusion 6a slide in the direction of the ink roller 1 along the slide portion 6c and the guide hole 2b, respectively, so that the smooth blade 6 is always in contact with the surface of the ink roller even if the diameter of the ink roller changes.

Furthermore, even if the diameter of the ink roller changes, the distance from the contact part d to the pressure contact part C
The circumferential length of the recording head 5 must be kept constant, but since the recording nozzle 5 is urged in the direction of the arrow r by the eccentric cam I7, the recording head 5 moves toward its support 15 as the diameter of the ink roller decreases. The guide protrusion 15b of the supporting side plate 16
It slides along the curved elongated hole 16a using the support protrusion 16b as a fulcrum. Therefore, the ink roller l and the recording head 5
The contact angle with the contact portion d and the circumferential length from the contact portion d to the pressure contact portion C are always kept constant.

Next, when the recording sheet 8 is conveyed, the recording sheet 8 fed from the feeding roller IO passes between the timing rollers 11 and is subjected to pressure on the sheet surface by the pair of rollers. Therefore, if the recording sheet 8 is made of paper or the like due to the above pressure, even if minute fibers are stretched on its surface or paper dust, etc. is attached, the fibers, paper dust, etc. will get into the paper. It is something. Therefore, even if the surface of the recording sheet 8 is fluffy or has low surface smoothness,
As the sheet passes between the timing rollers 11, the smoothness of the sheet surface is increased and transfer omission is prevented.

Generally, when pressure equivalent to pressure fixing by a copying machine is applied to the sheet surface, the smoothness of the sheet surface is increased.

Note that it is more effective for the timing roller 11 to be made of a metal roller in order to smooth the surface of the recording sheet 8 by the pressure contact, but at least the side where the recording sheet 8 contacts the ink roller l, that is, the recording If only the timing roller 11 on the side that contacts the transfer surface of the sheet 8 is made of metal, the same effect can be obtained even if the timing roller 11 on the other side is made of hard rubber or hard plastic.

Further, when the timing roller 11 made of hard rubber or hard plastic is used on one side as described above, it is preferable to install a vacuum cleaner below the roller 11 to collect minute dust such as paper dust.

Next, when removing minute dust such as paper dust attached to the surface of the ink roller 1, or when smoothing the surface of the ink roller 1 without performing a recording operation, the motor 21b
is rotated in the direction of arrow i.

At this time, the one-way flange 21c is in a locked state, rotating the eccentric cam 21 in the i direction, and the link member 20 is -
Rotate in the h direction. As a result, the rotating plate 13 rotates in the -g direction and pushes up the ink roller 1 to one side, so that the pressure contact between the ink roller 1 and the pressure roller 3 is released, and the gear 1b of the ink roller 1 meshes with the gear 2C. do. At the same time, when the motor 19f is driven and the lead screw member 19 is rotated in a predetermined direction, the NAND member 16C, which is threaded with the lead screw member 19, moves as shown by the arrow. As a result, the recording head 5 separates from the ink roller l. Note that the link member 20 is -h
Since the temporary slide 6b does not slide even when rotated in the direction, the smooth blade 6 remains in contact with the surface of the ink roller I, and the uneven member 24 is also maintained in pressure contact with the surface of the ink roller I.

In the above state, when the motor 2d is driven by a predetermined number (3), the ink roller l rotates and its surface is cut by the smoothing blade 6 to remove minute dust and the like and smooth it.

Further, at this time, the pressure roller 3 and the recording head 5 are separated from the surface thereof, so that wear of the recording head 5 and the like is prevented.

Incidentally, in the above embodiment, minute irregularities were formed by forming the surface of the uneven member 24 in a mesh shape, but in another embodiment, by roughening the surface of the metal roller,
A similar effect can be obtained by forming minute irregularities on the surface and using this as the irregular member 24.

Further, if a cleaning brush roller for cleaning the surface of the uneven member 24 is provided at a predetermined position, and the apparatus is configured to clean the surface of the uneven member 24 every time a predetermined number of sheets are recorded, the fine uneven surface on the surface of the uneven member 24 may be configured. This is effective because it prevents ink from clogging.

Further, in the above-mentioned embodiments, the transfer medium was configured in the form of a roller, but in other embodiments, the ink may be applied to the surface of a rotating drum, a rotating belt, or the like.

Similarly, the pressure roller 3, the supply roller 10, and the timing roller 11 are not limited to roller-shaped members, and the same effect can be obtained by using other members such as rotating belts.

Further, in the above-mentioned embodiment, the sliding protrusion 6b slides along the sliding portion 6C due to the pressure of the link member 20, and remains in contact with the surface of the ink roller 1 even when the pressure of the link member 20 is removed. However, if a friction member such as felt or rubber is provided on the slide portion 6C and the slide plate 6b is configured to slide on the friction member, the link member 20 will not be pressed (even if it does not slide). This is effective because the plate 6b can be reliably fixed in that position.

In addition, if the heating part of the recording head 5 is coated with silicone resin, the ink melted during heating will be transferred to the recording head 5.
It is possible to prevent the ink from adhering to the ink roller l, and to improve the slippage between the ink roller l and the ink roller l.

Further, in the above-mentioned embodiment, an example was shown in which the smoothing member 6 was configured in a knife shape, but in another embodiment, the surface of the ink roller 1 is smoothed by bringing a heating roller into contact with the surface of the ink roller 1. It may be configured as follows.

Further, in the above-mentioned embodiment, the recording sheet 8 is stored in the cassette 9, but the recording sheet 8 may be stacked on a deck, manual tray, or the like.

<Effects of the Invention> As described above, the present invention is configured so that the rotating transfer medium is heated by the recording head and a predetermined pressure is applied to the surface of the conveyed recording medium. Since it is not necessary and thermal efficiency for the transfer medium is good, running costs can be reduced. Further, since the uneven member capable of forming minute unevenness on the surface of the transfer medium is pressed against the surface of the transfer medium, it becomes easy to smooth the surface of the transfer medium after transfer with the smoothing member, and the smoothing effect can also be enhanced.
