Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a splicing block for accurately cutting a magnetic tape when editing the magnetic tape.

[Prior art and its problems]

Generally, when editing magnetic tapes, two magnetic tapes to be edited are overlapped, cut with a cutter, and the necessary parts are pasted together with adhesive tape.

In this case, a splicing block is used as an auxiliary jig to always accurately cut the magnetic tape at the same angle and to correctly paste the cut magnetic tape pieces together.

FIG. 3 shows a conventional splicing block 7. There is a tape groove 2 made to match the width of the magnetic tape, and a certain angle to the tape groove 2.
In this example, the cutter grooves 3 are arranged at an angle of 60° with respect to the longitudinal direction of the magnetic tape. When cutting magnetic tape, place the magnetic tape in tape groove 2, place the part you want to cut on cutter groove 3, and move the cutter blade along cutter groove 3 to always cut the magnetic tape at the same angle. I'm starting to be able to do it.

In the splicing block described above, the cutter blade is moved along the cutter groove 3, but the machining accuracy of the bottom 9 of the cutter groove 3 is difficult to achieve, and unevenness is formed, so the cutter blade is forced to move along the cutter groove 3. There was a problem that cutting the magnetic tape was difficult. Furthermore, since the base material 8 of the splicing block body is made of aluminum or plastic, there is a problem in that the cutter blade sinks into the bottom 9 of the cutter groove 3 and becomes jammed. On the other hand, it is conceivable to use a hard material such as ceramics as the base material 8 of the splicing block, but this would be difficult to perform precise processing and would be expensive, making it impractical.

[Purpose of invention]

The object of the present invention is to obtain a splicing block that can cut magnetic tape by moving smoothly without the cutter blade getting stuck.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention is such that a blade rest made of a material harder than the base material of the splicing block, such as ceramics, is arranged at the lower part of the cutter groove.

[Effect]

In the cutter groove, the part on which the cutter blade is pressed and slides, that is, the blade receiver provided at the bottom, is made of a hard material such as ceramics, so the cutter blade does not sink in and moves smoothly. In addition, the blade receiver placed at the bottom of the cutter groove has a simple structure and is easy to process, so it can be finished to a sufficiently smooth finish.

〔Example〕

FIG. 1 shows a first embodiment of the present invention. The base material 6 of the splicing block 1 is, for example, aluminum. The tape groove 2 is formed to match the width of a magnetic tape (not shown). The cutter groove 3 is
It is arranged to cross the tape groove 2 at an angle of 60° to the longitudinal direction of the magnetic tape. A blade receiver 5 formed of a round bar made of ceramics, which is a harder material than the base material 6, is embedded under the cutter groove 3.
The bottom portion 4 is formed by a part of the surface of a blade holder 5 formed of a round bar made of ceramics. .

FIG. 2 shows a second embodiment of the present invention. The base material 11 of the splicing block 10 is, for example, aluminum. The tape groove 2 is formed to match the width of the magnetic tape, and the cutter groove 3 is arranged to cross the tape groove 2 at an angle of 60 degrees to the longitudinal direction of the magnetic tape. A blade rest 14 made of a ceramic plate, for example, is embedded under the cutter groove 3, and a blade rest 14 made of a ceramic plate is embedded at the bottom 15 of the cutter groove 3.
It is formed by a part of the surface of 4. Although the plates 12 and 13 may be made of any material, for example, they are made of aluminum here. In the first embodiment, the base material 6 of the splicing block is made of one element, so it is possible to easily improve the machining accuracy of the base material 6, and in the second embodiment, the number of elements is plural. Since each element has a simple shape, it can be easily processed.

〔effect〕

As described above, according to the present invention, by arranging the blade receiver made of a material harder than the base material of the splicing block at the bottom of the cutter groove, the cutter blade can be cut when cutting the magnetic tape. A splicing block that can be moved smoothly without getting stuck in the grooves can be obtained.
