Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tape cartridge having a nameplate attached to the outer surface of the main body case.

[Conventional technology]

The outer surface of a tape cartridge generally has various markings on it, such as specification markings such as length and characteristics of the tape, and origin markings such as product name and manufacturer's name.

For example, in Japanese Utility Model Application Publication No. 58-52990, a label on which a source indication and a specification indication are printed is attached to the main body case, but the above-mentioned label is easily torn by contact with other objects.

Therefore, the present applicant previously proposed a metal nameplate with various indications attached to the outer surface of the main body case, thereby making it possible to display various types of indications with excellent durability. 1-97586).

However, this nameplate is processed by punching out a metal plate, but burrs are inevitably generated due to the punching, and burrs also occur when the nameplate is molded from hard plastic material. Sometimes. Although such burrs can be removed by polishing or the like after punching or molding, productivity decreases and processing costs increase accordingly. On the other hand, if the nameplate 13 is fixed to the outer surface of the main body case with burrs still formed, the nameplate 13 will float or come off.

The present invention was made in order to solve these problems, and its purpose is to ensure that various types of highly durable displays are possible, and to avoid problems caused by burrs caused by punching of nameplates. do.

[Means to solve the problem]

In the tape cartridge of the present invention, for example, as shown in FIG. Nameplate 13 on the outer surface of
A groove 22 is provided to accommodate the burr 19 generated on the edge of the groove.

[Effect]

Since the nameplate 13 polymerized and fixed to the outer surface of the main body case 1 is made of a hard material, it will not be easily torn by rubbing against other objects.

If the burr 19 generated on the nameplate 13 is accommodated in the groove 22, the nameplate 13 can be prevented from lifting or peeling off from the main body case 1.

〔Effect of the invention〕

According to the tape cartridge of the present invention, the hard nameplate 13 with various tape-related indications 17 is attached to the main body case 1.
Because it polymerizes and adheres to the outer surface of the label, it does not tear easily due to rubbing against other objects like conventional labels.
This has made it possible to display various types of displays with excellent durability.

Since the burr 19 of the nameplate 13 is accommodated in the groove 22 on the outer surface of the main body case l, it is possible to prevent the nameplate 3 from lifting or peeling off, and since it can be assembled without going through a special burr removal process, productivity is improved. This is advantageous in that it can improve performance and reduce costs.

〔Example〕

An embodiment of the tape cartridge according to the present invention will be described based on the drawings.

In FIGS. 1 and 2, the main body case 1 is formed by abutting upper and lower plastic cases 1a and 1b and integrally connecting them with screws or the like.

On the left and right of the center of each main wall 2 of the upper and lower cases 1a and 1b,
Drive shaft insertion holes 3, 3 are formed in a vertically penetrating manner, respectively, and hubs 6, 6, on which tape 5 is wound inside the main body case 1, are positioned above each drive shaft insertion hole 3, 3 so as to be rotatable, respectively. It is arranged.

As shown in FIG. 3, each main surface wall 2 has each drive shaft insertion hole 3.
・Short annular bosses 7, 7 are integrally provided inwardly protruding from the edge of the hole 3, and each hub 6 is fitted onto the outer periphery of the boss 7, so that the amount of free movement in the radial direction is restricted by contact. Ru.

The tape 5 fed out from one hub 6 is led out to the front of the case via guide rollers arranged on the left and right sides of the front end inside the main case 1, and then wound around the other hub 6.

As shown in FIGS. 1 and 5, a transparent window plate portion 11 is provided on the main wall 2 of the main body case 1 between the left and right drive shaft insertion holes 3 and 3 for visually checking the remaining amount of tape. The transparent window plate portion 11 is integrally molded from a transparent plastic material using a two-color molding method when the upper and lower cases 1a and 1b are molded. That is, after the main bodies of the upper and lower cases 1a and 1b are primarily molded from an opaque plastic material, the transparent window plate portion 11 is secondarily molded from a transparent plastic material. At the center of the transparent window plate part 11, as shown in FIG.
2 protrudes upward.

A metal nameplate 13 is retrofitted to approximately the center of each main wall 2 of the main body case 1, that is, to the outer surface of the main wall 2 including the left and right drive shaft insertion holes 3.

The nameplate 13 has an elliptical shape as a whole when viewed from above, and shaft insertion holes 15, 15 corresponding to the drive shaft insertion holes 3, 3 are provided on the left and right sides of the nameplate 13, passing through the drive shafts 3, 3, and both wheels. A horizontally elongated window hole 16 corresponding to the protrusion 12 is formed between the insertion openings 15 and 15 so as to penetrate vertically.

As shown in FIG. 6, the nameplate 13 has various indications 17 on its surface, such as the type and length of the tape or the name of the manufacturer.

The nameplate 13 is, for example, an aluminum plate with various markings 1 on it.
After etching and coloring 7, the outer shape and internal holes are punched out using a press. This nameplate 13
As a result of punching, burrs 19 are formed on the outer periphery and the inner periphery of the window hole 16 toward the back side, as shown in FIGS. 5 and 7.

At the edge of each shaft insertion opening 15 of the name plate 13, an annular shaft guide portion 21 is formed to protrude inward, as shown in FIGS. 3 and 4. As shown in FIGS.

Here, to briefly explain the processing procedure for the nameplate 13, the display 17 is etched and colored on an aluminum plate, and then the outer shape and hole are punched out by press working.

Next, the shaft insertion port 15 is burred, and then the shaft guide part 2
After carrying out the grinding process of step 1 and alumite treatment so that the entire surface appears golden, as shown in FIG. 6, a display 17 of arbitrary small characters or figures is added by silk printing, and the display 17 is further engraved.

A transparent window plate portion 11 is provided on the outer surface of each main wall 2 of the main body case 1.
As shown in FIG. 1, an elliptical recess 23 is formed which almost matches the name plate 13 and is slightly larger than the name plate 13.

On the inner bottom surface of the recess 23, along the contour line of the recess 23,
The name plate 13 is placed around the hem of the protrusion 12 of the transparent window plate portion 11.
A groove 22 is provided to accommodate the burr 19 that is generated.

For example, when the thickness of the main wall 2 is set to 1.81 m and the thickness of the nameplate 13 is set to 0.4 m, the depth of the recess 23 is set to 0.6 m to 0.6 m.
0.7 m, and the groove 22 has a width of 0.3 to 1. Otm, the depth is set within the range of 0.05 to 0.2.

Then, as shown in FIG. 4, the nameplate 13 is polymerized and fixed in the recess 23 via an adhesive 24, or press-fitted into the recess 23 without using the adhesive 24, and polymerized and fixed. In this fixed state, the ridge 19 protrudes from the back side of the nameplate 13.
is accommodated in the groove 22, and the outer surface of the nameplate 13 is flush with the outer surface of the main wall 2, or is 0.1
Let it sink to about tm.

When the nameplate 13 is superimposed and fixed in the recess 23 of the main body case 1 with the burr 19 accommodated in the groove 22 in this manner, the nameplate 13 can be prevented from coming out from the recess 23 or peeling off.

Further, the shaft guide portion 21 of each shaft insertion port 15 of the nameplate 13 is positioned so as to fit in contact with the edge portion (inlet portion) of each drive shaft insertion hole 3, as shown in FIG.

Further, as shown in FIG. 5, the protrusion 12 of the transparent window plate part 11 is fitted into the window hole 16 of the name plate 13 to form a transparent window for visually checking the amount of tape wrapped around each hub 6, The surface of the protrusion 12 is positioned on the same plane as the outer surface of the nameplate 13. In other words, if the outer surface of the flat transparent window plate part 11 is simply covered with the nameplate 13, a recess corresponding to the thickness of the window hole 16 will be formed, and dust will easily enter and accumulate inside the recess, and the inside of the case will be damaged. Since it becomes difficult to see, this problem was solved by providing the protrusion 12.

According to such a tape cartridge, even if it is placed in a high-temperature environment such as inside a car exposed to direct sunlight, the metal nameplate 13 remains intact.
Since the coefficient of thermal expansion of is smaller than that of the main case 1 made of a thermoplastic material such as styrene resin, the shape of each shaft insertion port 15 and the accuracy of the distance between the center axes of both insertion ports 15 can be maintained. .

Even if the nameplate 13 is heated by direct sunlight, the plastic main wall 2 prevents heat conduction, so the entire main wall 14 and the wall portion around the drive shaft insertion hole 3 including the boss 7 are completely heated in the inner and outer directions. Compared to a case made of metal, the internal hub 6 and tape 5 can be better prevented from being directly affected by heat.

Note that when the metal reinforcing plate is insert-molded to be buried in the plastic material constituting the main body case 1, warpage deformation occurs due to the difference in thermal expansion coefficient between the plastic material and the metal reinforcing plate. In this respect, since the nameplate 13 is also fixed to the outer surface of the main wall 2 of the case with an adhesive 24, even if the thermal expansion coefficients of both 2 and 13 are different, slipping occurs through the adhesive 24, and the nameplate 13 and the portion of the main wall 2 to which it is fixed will not be warped or deformed due to heat.

When the transparent window plate part 11 is molded integrally with the main wall 2 by two-color molding as in the above embodiment, the integral joint part P between the transparent window plate part 11 and the main wall 2 (see FIG. 5) but,
It tends to come off when a presser load is applied to the transparent window plate part 11 from the outside. However, in the above embodiment, the nameplate 13 is superimposed and fixed in such a manner that it covers the upper part of the integral joint part P between the transparent window plate part 11 and the main wall 2, so that it is easy to prevent the integral joint part from coming off due to external loads. This is advantageous because it can be prevented.

[Another embodiment example]

The fixing of the nameplate 13 to the main wall 2 of the main body case 1 can be arbitrarily selected, such as by providing a protrusion on one side and a hole on the other side so that the nameplate 13 is fitted in a recessed manner to prevent removal.

The nameplate 13 is not limited to the main wall 2 of the main body case 1, but can be fixed to any arbitrary position such as a part of the peripheral wall.

The nameplate 13 is not limited to a completely flat plate, but may also have a three-dimensional uneven shape.

When the nameplate 13 is made of metal, in addition to the aluminum plate, other metal plates such as stainless steel plate, copper plate, or steel plate can be selected, or hard plastic material such as phenolic resin containing glass fiber can be selected. can also be used. The thickness of the nameplate 13 can be set arbitrarily as long as it is equal to or less than the thickness of the main wall 2;
It is preferable to set it to 115.

In addition, the present invention may be such that the name plate 13 is superimposed and fixed only to one of the upper and lower cases 1a and 1b. Upper and lower main walls 2・
When attaching name plates 13, 13 as shown to both of the two name plates 13, the display 17 can be placed on only one name plate 13 and omitted on the other.

In the above embodiment, a Philips type tape cartridge is used, but the present invention is not limited thereto and can be applied to other types of tape cartridges such as various types of bidets and DATs.
