Abstract

PURPOSE:To attain the connection between a magnetic tape and a leader tape without injuring the magnetic tape despite the small length of the leader tape, by tilting a cassette connected with the leader tape to a holding block of the magnetic tape and connecting both tapes. CONSTITUTION:A cassette holer 24 which stores a cassette connected with a leader tape is attached to a rotary shaft 26 supported by a bearing 27. A universal link 54 is connected to the holder 24. Therefore the holder 24 can be titled to a tape holding block 45 by advancing a shaft 55 toward the bearing 27. In such constitution, the holder 24 is tilted when a magnetic tape held by the block 45 is connected to the leader tape led out of a cassette case which is stored to the holder 24. Thus it is not needed to fold sharp the leader tape despite its small length. This avoids injuries given to the magnetic tape when it is connected to the leader tape.

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a tape winding device that winds a magnetic tape into a tape cassette case to complete a magnetic tape cassette, and particularly relates to a process of cutting and joining a leader tape and a magnetic tape. This invention relates to a tape winding device that has been improved.

[Technical background]

First, referring to FIG. 1, the process of wrapping a magnetic case into an empty tape cassette case to complete a magnetic tape cassette will be explained.

FIG. 1A is a plan view of a tape cassette case. An empty reel 13 is housed in the tape cassette case, and reels 2 and 3 are connected in advance with a leader tape.

Then, as shown in Figure 1, the tape cassette case/
There is a front pig on the front! There is a front pig! is able to rotate around a fulcrum. Front pig! When it is turned as shown in FIG. 1C, the leader holder shown in FIG. 1A is exposed from the tape cassette case.

Next, the procedure for winding the magnetic tape into the reel coater 3 as shown in FIG. 1a will be explained.

First of all, the front cover of the tape cassette case/! Rotate to expose the leader tip. Next, pull out the leader chigeta and cut it. The cut end is connected to one end of the magnetic tape, and the magnetic tape is rotated three times to reel in the magnetic case along with the leader. Next, the magnetic case cassette is completed by cutting the magnetic case and connecting the cut end to the cut lI9'r end of the remaining leader tape.

[Conventional technology and its issues]

Conventionally, a device for completing a magnetic case cassette using the above-described procedure is, for example, the dI8Kunishojr-/7j/7.
No. 2 and Tokukai Akira! Otsu-/! Otori! 0 shown in the number
However, in the conventional tape winding device, Fig. 1a
This was inconvenient for case d, where the leader height was short as shown in d. The reason for this is that in conventional tape winding devices, when connecting a magnetic tape and a leader tape, it is necessary to significantly shift the position of the connection from the tape cassette case.

The cause of this problem will be explained below with reference to the main parts of the joint in the conventional magnetic tape winding device shown in FIG.

Note that since the detailed configuration of each part is already known, only the positional relationship of each component will be shown.

In FIG. 2a, 2 is a panel pace of a magnetic tape winding device, and r is a holder of a tin slicer that can be moved up and down. An adhesive case is held at the tip 10 of the Suge 2 Iserta. 1 is a tape cassette case, and a leader leader is pulled out from the tape cassette case and held on a tin rising block 11.

At this time, the Suge Rising Block/I and the tape cassette case L are positioned in a straight line so that the leader tape q does not bend. Cut 4t of leader tapes and attach the adhesive held at the tip 10 of the splicer 9. Figure 2 shows the case where the tape is connected to the magnetic tape.
That is, the tape cassette case is moved away from the panel space 7 and brought closer to the Suzuraishi/Guzlock TTF panel base 7 while the leader leader is held on the Suzu Rising Block //.

Note that since the detailed configuration of each part is already known, only the positional relationship of each component will be shown.

In Figure λ, 7 is the panel pace of the magnetic tape winding device, and r is the vertically movable splicer 9.

Figure t shows the case where the leader wire is cut in a straight line position so that the leader wire will not bend and is connected to the magnetic tape using the adhesive tape held at the tip 10 of the splicer 9. ) K is shown. That is,
The tape cassette case / is moved away from the panel pace 2 while the leader Qi geta is held on the sedge rising block //, and the sedge rising block /l is brought closer to the panel pace 7.

At this time, the position of the sedge rising block // is the same as the position of the sedge 2 iserter, and the position of the tape cassette case l is such that the sedge rising block // is the same as the position of the sedge rising block 7.
With this configuration, 4 tons of leader tape is enough to shift the position of the tape cassette case L without bending the leader getter sharply or damaging it. must be made longer.

[Means for solving the problems of the present invention]

In the present invention, in order to solve the above problems, when cutting the leader tape and connecting it to the magnetic tape, the amount of displacement between the connection location and the tape cassette case is reduced, and the tape cassette case The connection is made by tilting the tape so that even if the leader tape is short, the leader tape will not be buried by 11 cm.

[Configuration of the present invention]

The present invention is a magnetic tape winding device that winds a magnetic tape into a tape cassette case that incorporates seven pairs of empty reels connected by a leader tape, and supplies the magnetic case by rotating a magnetic case reel. reel stand and
A cassette holder that holds the tape cassette case,
a leader tape pulling means for pulling out the leader tape from the tape cassette case held in the cassette holder; and a tape holding block holding the leader tape and magnetic tape pulled out from the tape cassette case;
A cutting means for cutting the magnetic tape and the leader tape held by the tape holding block; a tape joining means for joining the magnetic case and the leader tape held by the tape holding block; and when joining the magnetic tape and the leader tape, cassette holder tilting means for tilting the cassette holder with respect to the tape holding block;
The gist of the invention is a magnetic tape winding device that includes a winding drive shaft that rotates a reel built into a tape cassette case.

[Actions and effects of the present invention]

The operation of the above configuration will be explained. First, a reel of magnetic tape is mounted on the supply reel stand, and one end of the magnetic tape is held in a tape holding block. The cassette holder K holds the tape cassette case, and the leader tape is pulled out from the tape cassette case by the leader tape pulling means. The pulled leader tape is held in a tape holding block separate from the magnetic case. The leader tape held by the tape holding block is cut by a cutting means.

Then, the magnetic tape held by the tape holding block is connected to the magnetic tape held by the tape holding block by tape joining means such as a leader tape. Thereafter, the cassette holder is tilted back to its original position, and the reel built into the tape cassette case is rotated by the take-up drive shaft to wind the magnetic tape onto the reel. When winding of the magnetic tape is completed, the rotation of the reel is stopped, the magnetic tape is held by the tape holding block, and the tape is cut by the cutting means. Again, tilt the cassette holder against the tape holding block.
As described above, the tape cassette is completed by joining the leader tape and magnetic tape.

As described above, the cassette holder holding the tape cassette case with respect to the tape holding block is tilted with respect to the tape joining block, so even if the leader tape pulled out from the tape cassette case is short, the leader tape or magnetic tape A leader tape and a magnetic tape can be joined without applying excessive deformation.
