Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus for recording by recording ink contained in an ink sheet on a recording material.

[0002]

2. Description of the Related Art Today, facsimile machines are widely used not only in offices but also in general processes. In order to facilitate miniaturization of these facsimile apparatuses, a so-called heat-sensitive recording method using a heat-sensitive sheet that develops color by heating is generally used. However, in recent years, a so-called thermal transfer recording type facsimile apparatus using an ink sheet has also been developed. The facsimile apparatus according to the thermal transfer recording method has an advantage that plain paper can be used as a recording material and an image can be recorded clearly.

[0003]

However, since the ink sheet is an extremely thin sheet, wrinkles easily occur. Therefore, it has been troublesome to load the ink sheet into the main body of the recording apparatus without generating wrinkles on the ink sheet. Therefore, in recent years, a method of accommodating the ink sheet in a cartridge and loading or exchanging the cartridge in the apparatus main body has been proposed.

When recording is performed using the ink cartridge, the ink sheet and the recording sheet are conveyed between the recording head and the platen roller, and the recording head is selectively heated to apply the thermal transfer ink applied on the ink sheet. The transfer recording (including the heat melting property and the heat sublimation property, the same applies hereinafter) is performed on a recording sheet. By the way, when detecting the remaining amount of the ink sheet, a highly reflective paint is applied in advance to a predetermined position from the end of the back surface of the ink sheet (for example, on the back surface side separated by x from the final end of the ink sheet). A coating with high reflectivity is applied in the range of width y to width z), and light is radiated from a reflective sensor provided in the ink sheet transport path to detect reflected light from the paint by the reflective sensor. The presence / absence of the ink sheet is detected by notifying the user of the ink sheet shortage through a display means such as an LED. Although the numerical values of x, y, and z can be set arbitrarily, they are generally set so that a reflective sensor can detect the paint and subsequently print several recording sheets.

However, according to this method, the coating material applied to the back surface of the ink sheet is transferred to the ink on the front surface side (printing surface side) to deteriorate the image quality, and the manufacturing cost of the ink sheet increases, Further, there is a defect that the reflection type sensor does not operate accurately due to the flapping of the ink sheet.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a recording apparatus capable of accurately detecting the remaining amount of an ink sheet at low cost while maintaining high image quality.

[0007]

A typical means for solving the above-mentioned problems of the prior art and applied to the embodiments described below is to supply a supply reel around which an ink sheet is wound and to wind up the ink sheet. An ink sheet cartridge having a take-up reel, a loading section into which the ink sheet cartridge can be loaded, and an ink sheet mounted on the ink sheet cartridge loaded in the loading section are acted to perform recording on a recording material. A recording means and a conveying means for conveying the recording material are used, a highly reflective member is used for the supply reel, and a reflection sensor is used as the number of ink sheets wound around the supply reel decreases. It is characterized in that it is moved in the axial direction of the supply reel while maintaining a constant distance from the ink sheet.

[0008]

According to the above construction, a highly reflective member is used for the supply reel, and as the number of ink sheets wound around the supply reel decreases, the reflection sensor of the supply reel is kept at a constant distance from the ink sheet. Move in the axial direction.

[0009]

Next, the structure of the loading section 5 for loading the ink cartridge A will be described. Recording cover 11
As shown in FIG. 7, positioning members 28 formed symmetrically are attached to both sides of the. The positioning member 28 is for fitting the key-shaped groove 28a for locking the guide pin 4e of the ink cartridge A and the bearing 8 fitted on both ends of the reels 2 and 3 for positioning the bearing 8. U-grooves 28b and 28c are provided on the same extension line at a predetermined interval. A locking spring 29 for locking the locking projection 4n of the ink cartridge A is provided near the open end of the recording cover 11.

Therefore, as shown in FIG. 7, the guide pin 4e of the ink cartridge A is fitted and locked in the hook-shaped groove 28a, and the ink cartridge A is rotated around the guide pin 4e, as shown in FIG. As described above, by locking the locking protrusion 4n to the locking spring 29, the ink cartridge A
Is loaded on the recording cover 11. At this time, the bearing 8 has a U groove 28
They are fitted to b and 28c, respectively.

At the time of loading, since the guide pins 4e of the ink cartridge A and the U grooves 4c and 4d in which the bearings 8 are fitted are arranged in a straight line, the ink cartridge A is rotated around the guide pin 4e. Sometimes, the bearings 8 of the supply reel 2 and the take-up reel 3 have U-grooves of the positioning member 28.
It is positioned almost simultaneously with respect to 28b and 28c. Therefore, the bearing 8 is securely positioned and fitted into the U grooves 28b and 28c of the positioning member 28.

Further, since the guide pin 4e and the U grooves 4c and 4d into which the bearing 8 is fitted are both provided on the side of the first casing 4a and are arranged in a straight line, these positioning members are arranged. Key-shaped groove 28a and U groove 28 formed in 28
By arranging b and 28c in a straight line, the bearing 8 is accurately positioned with respect to the guide pin 4e. That is, a high positional accuracy can be obtained when positioning the bearing 8 simply by arranging the hook-shaped groove 28a and the U-shaped grooves 28b, 28c on the positioning member 28 which is one member.

In the thickness direction of the positioning member 28 of the present embodiment, as shown in FIG. 10 (a), when the inner side surface 28d is below, the distance between the positioning members 28 is wide, and as it goes upward, it becomes narrower. It is formed in a tapered shape. As a result, when the ink cartridge A is rotated around the guide pin 4e, the ink cartridge A is guided along the taper so that the ink cartridge A can be easily loaded.
Does not rattle in the reel axis direction (direction of arrow Y in FIG. 8).

Further, when the ink cartridge A is loaded as described above, as shown in FIG. 11, the fork member 6d attached to the recording head 6a twists the lid 4g of the ink cartridge A and urges the coil spring 4i. The recording head 6a is inserted into the cartridge through the opening 4f of the ink cartridge A.
When the recording head 6a is inserted into the opening 4f,
Since the guide pin 4e is provided at the end of the cartridge A and there is a certain distance from the guide pin 4e, which is the center of rotation, to the opening 4f, the size of the opening 4f is such that the recording head 6a is inserted. It is possible to make the size almost equal to the minimum required size.

As shown in FIG. 12, the biasing force of the lid 4g by the torsion coil spring 4i (the force to return the lid 4g to the closed state) is applied to the platen roller 6b by inserting the recording head 6a into the cartridge. It is a force that does not affect the pressing force when pressed. Therefore, in this embodiment, the pressure contact force between the recording head 6a and the platen roller 6b by the pressing spring 6c is set to about 15 gf / cm, while the lid 4 by the torsion coil spring 4i is set.
The urging force of g is set to about 60 gf / cm. When the ink cartridge A is loaded, the recording head 6a covers the lid 4
Since g is opened to the end and inserted into the cartridge A, the cartridge A can be easily loaded. Further, since the lid 4g is opened in a double-door type by the pressing of the recording head 6a, the turning radius of each lid 4g is small, and the length of the ink cartridge A in the height direction can be shortened.

When the ink cartridge A is loaded as described above, the reflective sensor 63 is urged by the spring 64 from the opening 65 provided in the first housing 4a to press the supply side ink sheet 1 in the cartridge. Is configured.
The reflective sensor 63 moves in the axial direction of the supply reel 2 as the supply side ink sheet 1 decreases.
When it hits the highly-reflective supply reel 2, it detects the ink sheet shortage. When an ink sheet shortage is detected during printing, the page memory provided in the control unit 50 stores the page in the middle of printing and the image data after that page in the memory without printing, and the display unit 53 The indication that the ink sheet is out is displayed on.

Although not shown in this embodiment, the reflective sensor 63 is constructed so as not to damage the surface of the ink sheet on the supply side, and the reflective sensor 63 is not damaged when the cartridge is inserted. Has become.

As described above, the ink cartridge A is attached to the recording cover 11 (see FIG. 8), the recording cover 11 is closed, and the hook 30b of the apparatus body 10 and the hook 30 of the recording cover 11 are closed.
Lock a and. At this time, the reel gears 2c and 3c integrally formed with the supply reel 2 and the take-up reel 3 are configured to mesh with the drive transmission gear 31 attached to the apparatus main body 10 side.

To explain this concretely, as shown in FIG. 8, a reel drive motor 32 for driving and rotating the reels 2 and 3 is attached to the main body 10 side of the recording apparatus B. Driving force is transmitted to the driving force transmission gear 31 via the gear trains 33a to 33e. The gear 33e is attached to an arm 34 that is rotatable about the gear shaft of the gear 33d, and is configured as a so-called pendulum gear that can swing around the gear 33d while being meshed with the gear 33d. There is. And the driving force transmission gear
Reference numeral 31 is swingable integrally with the pendulum gear 33e, and the rotational force from the pendulum gear 33e is transmitted via the slip clutch 35. In FIG. 8, reference numeral 36 is a tension spring for pulling the arm 34 upward.
Further, 37 is a platen motor for rotating the platen roller 6b, and the driving force of this motor 37 is a gear train 38
It is transmitted to the platen roller 6b via a to 38c.

In the above structure, when the recording cover 11 is closed, the reel gears 2c and 3c exposed from the opening 4m of the ink cartridge A come into mesh with the driving force transmission gear 31. The opening 4m is shown in Fig. 13.
As shown in (a) and (b), the reel gears 2c and 3c are provided so as to be located on the circle of the rotation locus of the hinge shaft 12 of the recording cover 11, and the driving force transmission gear 31 is also provided. It is provided so as to be located on the trajectory circle. Therefore, when the recording cover 11 is closed, the gears 2c and 3c exposed from the opening 4m press the driving force transmission gear 31 to surely mesh with each other. At this time, even if the parent gear 33d connected to the reel drive motor 32 is in the locked state, the pendulum gear 33e that swings integrally with the driving force transmission gear 31 is the parent gear 33.
The recording cover 11 can be smoothly closed because it smoothly swings around d.

On the side of the apparatus body 10, as shown in FIG. 8, the ink cartridge A attached to the recording cover 11 is provided.
Leaf springs 39 serving as pressing members are attached to the bearings 8 at positions facing the bearings 8.
Are pressed toward the U-grooves 28b and 28c of the positioning member 28. Therefore, the bearing 8 has a height direction (see FIG. 8) shown in FIG.
Positioning in the arrow Z direction) is reliably performed. The leaf spring 39 is positioned on the U of the positioning member 28 as shown in FIG.
The grooves 28b and 28c are attached so as to coincide with each other in the reel axial direction. For example, if the leaf spring 39 and the positioning member 28 do not match in the reel axial direction, the bearing 8
The twisting force acts on the reels, and unnecessary frictional force acts on the rotation of the reels 2 and 3. However, in the present embodiment, the inconvenience does not occur.

As described above, the bearing 8 serves as the U of the positioning member 28.
Positioning in the grooves 28b and 28c and positioning when the ink cartridge A is loaded in the recording cover 11 and positioning of the bearing 8 are configured independently. That is, since the bearing 8 is directly positioned on the recording apparatus B without passing through the ink cartridge A, it is possible to improve the accuracy such as the parallelism between the reels 2 and 3 and the platen roller 6b.
Further, since it is not necessary for the ink cartridge A to precisely position the bearing 8, it is not necessary to request the cartridge A for rigidity and precision. Therefore, the cartridge A can be manufactured at low cost.

Further, in this embodiment, when the recording cover 11 is closed, as shown in FIG. 14, the pressure contact portion between the recording head 6a and the platen roller 6b is located substantially in the center in the height direction of the ink cartridge A. Is configured. When the pressure contact portion is located above the ink cartridge A,
The notch 4l ₂ for releasing the shaft of the platen roller 6b shown in FIG.
When the pressure contact portion is located below the ink cartridge A, the opening 4f for inserting the recording head 6a must be formed large. However, in the present embodiment. Since the press contact portion is located at the substantially center, without weakening the strength of the second housing 4b,
Further, the opening 4f can be minimized.

Next, the case where recording is performed using the recording apparatus B loaded with the ink cartridge A will be described.
At the time of recording, the platen motor 37 and the reel drive motor 32 on the take-up reel side are driven, and the reel drive motor 32 on the supply reel side is locked. When the platen motor 37 is driven, the platen roller 6b rotates in the direction of arrow a in FIG. 14, and the recording sheet 7 and the ink sheet 1 superposed on it are conveyed in the direction of arrow b. In synchronization with this, the heating element 6a ₁ of the recording head 6a generates heat according to an image signal to heat the ink sheet 1 in an image pattern, and the ink melted by this heating is transferred to the recording sheet 7.

At the time of the recording, the motor for driving the take-up reel 3 has a rotational peripheral speed of the take-up reel 3 so that the ink sheet 1 conveyed by the platen roller 6b is not loosened. Drives slightly faster than the speed of the slip clutch
Absorb by 35. As a result, the ink sheet 1 is taken up by the take-up reel 3 while being given a front tension. On the other hand, the reel drive motor on the supply reel 2 side
Since 32 is locked, the supply reel 2 receives the slip load of the slip clutch 35 and rotates as the ink sheet 1 is fed out. A back tension is applied to the ink sheet 1 by this sliding load.

In FIG. 14, the front tension of the ink sheet 1 wound around the take-up reel 3 exerts a strong force on the sheet 1 to press the recording head 6a upward. Changes,
In an extreme case, an image may be missing, but in the present embodiment, since the ink sheet 1 is guided by the ink sheet guide members 60 and 61, even if the front tension of the ink sheet 1 is strong. The recording head 6a is not pressed upward by the ink sheet 1. Therefore, the pressing force of the platen roller 6b by the recording head 6a is always constant, and there is no possibility of image omission.

As shown in FIG. 14, the reel gear 2c on the side of the supply reel 2 is a driving force transmission gear that receives a sliding load.
The driven rotation of 31 receives an upward force, but since the bearing 8 is supported by the U grooves 28b and 28c from above, the bearing 8 does not move upward. That is, since the U grooves 28b and 28c are attached so as to regulate the direction in which the reel gears 2c and 3c are biased by the driving force transmission gear 31, the reel gears 2c and 3c do not move,
