Abstract

PURPOSE:To prevent fusion, deformation, etc. of a ribbon and extend the life of a print head or the like by bringing the ribbon into contact with a roll wetted with a prescribed compound. CONSTITUTION:A protective layer consisting of an organic fluorine or silicon compound is formed on the surface, which is brought into contact with a roll 3 wetted with a liquid of said compound and faces a thermal print head H, of a print ribbon 1 which is fed by a ribbon feeding mechanism 2 of a ribbon cartridge. Thus, the thermal resistance, the permeability resistance, and the lubricity of the ribbon 1 are improved and the water repellency and dirt-proof property are fed to prevent fusion and deformation of the ribbon due to heating by the head H, and the ribbon 1 is wound up well, and further, the life of the head H is extended. In case that the ribbon is a magnetic tape, similar effects are attained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in ribbon cartridges for computers, word processors, tape recorders, video tape recorders, and the like.

For printers attached to computers, W1/Prosensors, etc., we use polyester film tapes with a heat-melting ink layer, thermal transfer printing printers equipped with a phone, and ink on woven fabric. Ribbon force for wire l/nt printing with impregnated ribbon -1
・Recently, there is a strong demand for a 6-speed engine regardless of whether it is linked or used.

However, in order to meet the demand for higher printing speeds, the former thermal transfer printing blade hole must be heated to a high temperature instantaneously at the printing hem, and such high temperature is This leads to melting of the resin tape itself,
As a result, the ribbon may become wrinkled or deformed after it has passed through the printing vent, making it impossible to wind it, or it may adhere to the printing vent as molten matter or dirt, causing unclear printing and other problems. becomes more likely to occur.

On the other hand, in the latter wire dot printing method, the print head is naturally prone to staining because ink or ribbon seeps onto the surface facing the print head, and high-speed printing amplifies the accumulation of dirt on the print head, resulting in unclear print. Other problems are likely to occur.

In addition, even in devices that use magnetic tape, such as audio/visual equipment such as tape recorders and video tape recorders, and computers, the head becomes dirty due to dirt on the magnetic tape, and the friction between the magnetic tape and the head increases. This has a negative effect on the lifespan of the battery that drives the device, the lifespan of the magnetic head, and the sound and image quality.

The present invention attempts to solve these conventional problems by improving the ribbon cartridge.

The ribbon cartridge of the present invention is a cartridge equipped with a ribbon (1) and a ribbon feeding mechanism (2). The present invention is characterized in that the ribbon (1) is provided at a location before reaching the head so as to be in contact with the head facing surface.

In the ribbon cartridge of the present invention, the organic fluorine-based or organosilicon-based compound liquid is deposited onto the ribbon before the head, and the ribbon is fed with a droplet of 10%.
A layer of micron or submicron order having heat resistance, permeation resistance, and slipperiness is formed.

Therefore, if the ribbon is a ribbon for thermal transfer printing, even if a temperature higher than the melting temperature of the resin tape that makes up the ribbon is instantaneously applied to the print head, the resin tape will not melt, and the ribbon will have slippery properties. It also provides water repellency and stain resistance, so problems such as poor ribbon winding will not occur, and the life of the print head will be greatly extended, so that problems such as poor printing will not occur for a long time. become.

In addition, even when the ribbon is used for wire dot printing, the ribbon has excellent penetration resistance, slipperiness, and stain resistance, which reduces head stains caused by ink and makes the ribbon run extremely smoothly. This greatly extends battery life, ribbon life, and print head life, and eliminates problems such as curling, printing problems, and poor ribbon winding for a long time.

Similarly, when the ribbon is a magnetic tape used in tape recorders, video tape recorders, computers, etc., the magnetic tape has excellent slip properties and antifouling properties, which reduces the lifespan of the head and the magnetic tape that drives the magnetic tape. The battery life will be greatly extended, and the sound and picture quality will not deteriorate for a long time.

Examples of the organic fluorine compound used in the present invention include homopolymers or copolymers of tetrafluoroethylene, homopolymers or copolymers of vinylidene fluoride, homopolymers or copolymers of chlorotrifluoroethylene, and in particular, homopolymers or copolymers of tetrafluoroethylene. It is preferable to use a mixture of a homopolymer and a copolymer in an appropriate ratio. Here, the comonomer is
Examples include olefins, threatening olefins, perfluoroolefins, and fluoroalkyl vinyl ethers. A fluorine-based surfactant or a fluorine-based solvent can also be used together with these polymers or copolymers. These organic fluorine compounds are used in liquid form as they are or diluted with another solvent, and in solid form they are used as a dispersion or solution, but it is particularly desirable to use them as an aqueous dispersion.

As the organosilicon compound, silicone oil, silicone grease, oil compound, silicone varnish, etc. are used. It is more desirable to use this organosilicon compound in combination with the above-mentioned 1-organic fluorine compound than to use it alone.

In the present invention, a roll moistened with a liquid of an organic fluorine-based or organosilicon-based compound as described above is provided so as to be in contact with the head-facing surface of the ribbon.

Examples of the roll installation method will be listed together with the schematic diagrams shown in FIGS. 1 to 4. In addition, in Figs. 1 to 4, (1) is a ribbon, (3), (3a), (3b), (3c)
, (3d) are rolls, (5) are presser rolls or presser pieces made of elastic members attached as necessary to ensure close contact between these rolls and the ribbon (1),
(4) is a guide roll. Further, (H) shown by a chain line at -C,1 is a head.

li) As shown in Figure 1, a roll (3) made of a porous material such as a sintered body, foam, or felt material is impregnated with these liquids in advance, and this impregnated roll (3) is A method in which the ribbon (1) is brought into direct contact with the surface.

2. As shown in Figure 2, roll (3a) impregnated with liquid
A method in which the surface of the ribbon (1) is brought into contact with the surface of the ribbon (1) via another small roll (3b).

・3) As shown in Figure 3, a ring-shaped roll (3c) impregnated with a liquid is fitted into the Kiteroll (4), and this roll (3c) is brought into contact with the surface of the ribbon (1).

・4I As shown in Fig. 4, a liquid is sealed in the hollow part of a hollow roll (3d) made of a porous material, and this roll (3d) is passed through a ribbon (3d) directly or through another small roll.
1) Method of contacting the surface.

In addition, o-ru (3), (3a), (3b),
(3c) and (3d) are usually provided so as to rotate in the forward direction with respect to the running direction of the ribbon (1), but in some cases they may be fixedly provided or rotated with respect to the running direction of the ribbon (1). It can also be provided to rotate in the opposite direction.

Here, examples of the porous material include metals, plastics, fibers, and ceramics. It is more desirable to impregnate these porous materials with a liquid by vacuum impregnation than by mere impregnation under normal pressure. This is because selective absorption in which only specific components of the liquid components are preferentially absorbed is prevented, the number of areas impregnated with the liquid increases, and the time required for impregnation is shortened.

Contact of a roll moistened with the above liquid to the ribbon is
This is done on the side facing the head of both sides of the ribbon,
This makes the contact between the ribbon and the head extremely smooth, and at the same time prevents the ribbon from staining, melting, and ink penetration. Note that the roll may be in contact with not only the surface of the ribbon facing the head, but also the surface on the opposite side. In this case, the friction between the ribbon and the roll or guide roll that drives it is reduced, making it even better. The ribbon runs smoothly, and the amount of power required to drive the ribbon can be reduced.

The roll moistened with the liquid mentioned above may come into contact with the ribbon at any point in front of the head, or in the case of an endless belt-type ribbon that does not transfer ink, it may come into contact with the ribbon at any point during the ribbon running process, If the ribbon is a belt type ribbon and the ink is transferred, it should be at any point after the ink transfer point and before it reaches the head, and if the ribbon is run unilaterally from the supply reel to the take-up reel, it should be any point before it arrives at the head. .

Note that after the roll moistened with the liquid is brought into contact with the ribbon and before the ribbon portion reaches the head, drying means such as air blowing may be taken.

Ribbon cartridges designed by Kishi are used as printing cartridges and paperboards installed in printers of devices such as computers and word processors, cartridges for typewriters, magnetic tape cartridges installed in devices such as cheap recorders, video tape recorders, and computers. Useful.

The ribbon cartridge of the present invention will be further explained by giving examples.

Embodiment 1 FIG. 5 is a plan view showing an example of a ribbon cartridge of the present invention for thermal transfer printing.

(1) is a ribbon for thermal transfer, the base material of which is a polyester stretched film tape, and one side of which is provided with a layer of a heat-melting ink composition made of carbon black, binder, wax, etc.

(6) is the case, (7) is the supply side reel, (8)
is the take-up reel. (2) shows an example of the ribbon feeding mechanism for running the ribbon (1), and the rubber belt shown in 1. When the rubber belt (2) is driven counterclockwise in the figure, the surface of the belt (2) and the ribbon (1) are shown. ) Due to the frictional force with the surface, both the rules (7) and (8) rotate freely and the ribbon (
1) is configured to run from the supply reel (7) to the take-up reel (8).

- (H) indicated by a dashed line is a print head, and (P) indicated by a dashed dotted line is plain paper on which printing is performed.

Further, (3c) is a ring-shaped roll made of porous plastic impregnated with a fluorine resin liquid by a vacuum impregnation method, and is fitted into the guide roll (4). (5) is a sponge-like presser piece.

The composition of the fluororesin liquid impregnated into the roll (3C) is as follows.

Tetrafluoroethylene homopolymer 5% Tetrafluoroethylene copolymer 4% Silicone grease 5% Paraffinic high boiling point solvent 20% Brightener, surfactant, viscosity modifier, stabilizer 12% Water 54% Ribbon with such composition I installed the cartridge in a word processor printer and started printing, but even if I turned up the power and set the heating temperature in the print head (H) to a high temperature, the tape that is the base material of the ribbon (1) did not melt. Printing proceeded smoothly, and all of the ribbon (1) was wound onto the take-up reel (8), and the winding appearance was neat and beautiful.

On the other hand, when the impregnation roll (3C) marked with "-" was not used, increasing the power and heating the printing head (H) to a high temperature caused the deformation of the ribbon (1) due to the melting of the material tape. As the ribbon (1) is being wound up on the take-up reel (8), wavy irregularities can be seen in the winding appearance of the ribbon (1). ), the ribbon (1) is connected to the case (6
) and it became impossible to wind up the ribbon (1) itself.

Embodiment 2 FIG. 6 is a plan view showing an example of a ribbon cartridge of the present invention for wire dot printing.

(1) is an endless-held type ribbon made of nylon fabric, and is impregnated with ink. (2) is a drive roll as an example of a ribbon feeding mechanism for running this ribbon (1), (6) is a case, and (9) is a guide plate. The ribbon (1) runs smoothly simply by being taken up by the drive roll (2). In addition, (H) is the print head, (P) is the plain paper on which the first print is applied, and
(3) is a ceramic roll impregnated with a fluororesin liquid having the same composition as in Example 1 by a vacuum impregnation method, and (5) is a presser roll.

By installing a ribbon cartridge with such a configuration in a word processor printer, you can check the smoothness of the ribbon running over a long period of time, check the dirt on the printing spatula I" (H), and check the extent of printing blemishes. However, the above roll (3
) clearly superior results were obtained compared to the case without the installation.

Embodiment 3 FIG. 7 is a plan view showing an example in which the ribbon cartridge of the present invention is a cassette tape for a tape recorder.

(1) is a magnetic tape, (4) is a kit roll, (6) is a case, (7) is a supply side reel, (8) is a take-up side reel, and (3) is the same composition as in Example 1. This is a heavy sintered plastic roll impregnated with fluorine resin liquid using a vacuum impregnation method.

We installed a cartridge with this configuration in a portable cheap coater and investigated the deterioration of sound quality and battery life over a long period of time, but compared to the case where the roll (3) above was not installed, Since the tape (1) will not be damaged, the period until noise occurs will be significantly extended, and the tape (1) will not be damaged.
It was found that the battery's 11 lifespan was reduced by more than 20% because the battery was sent to Ennan.
