Is configured. This magnetic tape cartridge is
To prevent the reel from rotating inadvertently when not in use
A lock plate to hold the
From the release pad to unlock the lock
In the hub that is formed in the cup shape of the reel
In preparation. The lock plate has a cup shape of a reel.
A hub that can be engaged with and disengaged from an engaging portion protruding from the periphery of the bottom plate of the hub
The side that is always engaged with the side engaging part and the upper half engaging part
It is a disk-shaped member which has an engaging part in an upper surface center part. this
The lock plate is a compression core interposed between the upper half.
The hub side engaging part on the lower surface is cupped by the urging force of the spring.
By engaging the engaging part of the bottom plate of the hub,
It is kept locked. On the other hand, the release pad is a reel hub.
A roughly triangular shape interposed between the bottom and the lock plate
Or a rectangular plate-like member formed on the bottom of the hub
It has a plurality of unlocking pins inserted into the through holes
The This release pad has a magnetic tape cartridge
When the hub is rotated and loaded in the drive device,
Each unlocking pin inserted in the through hole on the bottom of the hub
The lock plate is pushed back to the lock plate side.
Push the belt against the compression coil spring toward the upper half,
The bottom side of the hub plate and the bottom side of the hub
Release the engagement with the engaging part and release the locked state of the reel.
The A magnetic tape cart constructed as described above.
In the process of assembling the ridge, on the belt conveyor
On the cartridge case on the parts transport pallet
Place the half, lower half and other internal parts
The upper half or lower half of the specified internal parts in each process
The method of assembling in the right place is used. The parts
The transport pallet is often used before transport and assembly.
Mounted with the coil spring standing on the lock plate
And conveyed in this state. And assembly robot etc.
Reel cup assembled in lower half by assembly device
Assembling the lock plate and coil spring in the hub
Is transported to the next process as it is,
Assembly of other internal parts to the door is performed. By the way, the coil spring is generally compressed.
A coil spring is used, but the compression coil spring has a wire diameter,
Various characteristics by changing the coil diameter and pitch
In this, paying attention to the diameter of the coil,
Cylindrical compression coil springs with a constant coil diameter,
The diameter of the rod gradually decreases from one end to the other
There are various types of conical compression coil springs. The latter cone
The compression coil spring has a small diameter side coil inside the large diameter side coil.
The contact length is small by setting the diameter so that the

It is sectional drawing which shows the state in which the lupine was mounted. The first
In the description of the third embodiment, the first and second embodiments
Parts that are substantially the same as the state are given the same reference numerals and detailed explanations are given.
I will omit the description. As shown in FIG. 10, the magnetic tape cartridge
Parts transport pallet 50 for transporting each part constituting the wedge
Keep the lower half 1A upward on the base plate 21.
Hold the first holding jig 22 and the upper half 1B downward.
Second holding jig 23 to be held, and a fine inner part to be assembled inside
Third to eighth holding jigs 24 for holding part parts (not shown)
To 29 are fixed so as to be detachable and replaceable. The second
1 In the center of the lower half 1A fixed to the holding jig 22,
Just below the circular opening 1D (see Fig. 1) of the lower half 1A
From the permanent magnet inside the base plate 21
The magnet M which becomes is incorporated. In other words, magnet M is carp
Directly below the assembly position of the lower spring 1 on the lower half 1A
positioned. As shown in FIG. 11, the parts transport pallet 5
0 is a base plate made of a thick metal plate as a whole
21 and the bottom half of the base plate 21
A field located directly below the 1A circular opening 1D (see FIG. 1)
A magnet M is arranged at the place. The size of the magnet M and
The shape does not need to be particularly limited.
Can be round, ring, elliptical, polygonal, etc.
Good. Further, the magnet M is assembled to the base plate 21.
The method of attaching is to be embedded in the base plate 21
Is provided with a recess in the base plate 21, and a magnet M is provided there.
It may be inset. The material of the base plate 21
Did not weaken the magnetic force to attract the coil spring 4
For this reason, it is desirable to use a non-magnetic material.
In the case of a body, magnetic flux is applied to the base plate 21.
Between the magnet M and the base plate 21 so as not to leak
It is better to isolate it with a non-magnetic material. The magnet used in the present invention
Stone M is strong enough to attract the coil spring 4
Yes, adversely affects the magnetic tape MT itself during the assembly process
It is not something. Next, the parts transport pallet of the third embodiment.
Explains how to assemble a magnetic tape cartridge using
Light up. First, the lower half on the upper part of the parts transport pallet 50
Configures 1A, upper half 1B and magnetic tape cartridge
Set each part to be fixed on each holding jig. And
The parts transport pallet 50 is assembled by the transport conveyor.
It is transported to the working position of the bot and the parts transport pallet 50
Above, assembly robot assembles reel 2 in lower half 1A
Attach the release pad into the cup-shaped hub 2A of the reel 2.
After assembling the head 5 and the lock plate 3 in order,
The coil spring 4 is placed on the plate body of the cup plate 3
The Next, the parts transport pallet 50 is moved to the next state as it is.
To the assembly robot's work position, where the lower half
1A includes a sliding door 6, a spring member 7, an erroneous erasure preventing claw,
Assemble the IC chip. And finally, the upper half 1B
The cross-shaped projection (not shown) on the inner surface of the lock plate 3
And push it into the half-side engagement part 3B
Assemble half 1B to lower half 1A. In the above process, the lock plate 3
When the coil spring 4 is placed, as shown in FIG.
The lower end of the spring 4 is a cross-shaped c
The coil spring 4 is inserted into the roof side engaging portion 3B,
Locked by the magnet M incorporated in the feeding pallet 50
It is attracted to the magnet M via the rate 3 or the like. Therefore
The coil spring 4 is temporarily mounted on the lock plate 3.
The next assembly robot using the parts conveying pallet 50 in the assembled state
Coil spring 4 is still on the lock plate 3
Will not fall over or fall off. As described above, the third embodiment of the present invention.
Although described, the present invention is not limited to the third embodiment.
I can't. For example, a magnet to attract the coil spring 4
A permanent magnet was used as M, but this could be used as an electromagnet.
Various effects can be obtained. Base plate 2
1 is made of a metal plate, but the base plate 21 itself
The same effect can be obtained even if the magnet is constituted by a magnet or an electromagnet. Furthermore, in the embodiment of the present invention, the set
The assembly robot is used for assembly work.
Manual assembly by humans and humans, or manual assembly by humans only
Even if it is assembly work such as construction work, work smoothly as well
Thus, the assembly failure of the coil spring 4 can be prevented. In the assembling process of the present invention,
Assemble sequentially from 1A, but upper half 1B
When assembling from the place where the coil spring 4 is placed
In the parts transport pallet 50 at a position corresponding to the lower part of
It is possible to obtain the same effect by incorporating stone M
