Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a storage box that removably stores a disk cartridge equipped with a movable light protector. This invention relates to a disk cartridge storage box that automatically displaces a protector to a write-protected state.

[Conventional technology]

Some disk cartridges, such as magnetic disk cartridges in which a recording medium is housed in a cartridge case made of a hard case, are equipped with a write protector mechanism that makes it impossible to write or erase information on the recording medium. This light protector function is usually achieved by providing a through hole in the cartridge case, installing a slider to open and close the through hole, and slidingly displacing this slider with your fingers or the like.
By opening and closing the through hole, the write protector is switched between a write-inhibited state and a write-inhibited state, and this is detected by a detection means built into the recording and reproducing apparatus.

[Problem that the invention attempts to solve]

As mentioned above, if the write protector is used as a slider to control switching between the write inhibit state and the inhibit release state,
There is a possibility that a magnetic disk cartridge may be mistakenly inserted into a recording/reproducing apparatus while the prohibition is canceled, and as a result, there is a possibility that necessary recorded contents may be erased.

In the present invention, in view of the above points, a disk cartridge has a head insertion hole etc. in the cartridge case, and dust etc. can enter through this head insertion hole, and fingers and other objects can In order to protect the recording surface that is exposed to the outside at the position where the insertion hole is opened in the head from being soiled or damaged, we focused on the fact that it is handled while stored in a storage box, and we have added safety features to this storage box. The purpose of this is to ensure that erasure of recorded contents due to malfunction can be prevented.

[Means for solving problems]

In order to achieve the above-mentioned object, the disk cartridge storage box according to the present invention is provided with a slider in a cartridge case containing a recording medium, and the displacement of the slider makes writing and erasing on the recording medium impossible. A write protector for switching between a write-prohibited state and a write-inhibited state is provided on the inner surface of a storage portion that removably stores a disk cartridge, which engages with the slider when the disk cartridge is stored. The device is characterized in that it is provided with an engaging member that displaces it into a write-inhibited state.

[Effect]

Therefore, even if the write protector of the disk cartridge is in a write-inhibited state, when the disk cartridge is inserted into the storage box, the slider that constitutes the write protector engages the operating member. Then, when the slider is pushed and the disk cartridge is completely stored in the storage box, it is shifted to the write-inhibited state. Therefore, when taking out the disk cartridge from the storage box, the write protector always switches to a write-protected state, and even if you accidentally write or erase the data on the recording/playback device, the write protector will not be able to write to it. or deletion becomes impossible. Needless to say, if the slider is moved again to switch to the write inhibited state, it becomes possible to erase the writing on the recording medium.

Detection of whether the write protector is in a write-inhibited state or in a write-inhibited state is performed by a detection means built into the recording/reproducing device, but this detection may also be performed by detecting the position of the slider itself. Alternatively, the cartridge case may be provided with a through hole that is opened and closed by the slider, and when the through hole is open, it may be detected as a write-inhibited state of the write protector. In this case, if the storage box or the engagement member is made of an elastic member and the engagement member is fitted into the through hole, this fitting will allow the disk cartridge to be removed from the storage box when not in use. This prevents the storage box from escaping, allowing the storage box to fully demonstrate its function of protecting the recording medium.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. First, as shown in FIGS. 4 to 6, a disk cartridge 1 has upper and lower cover pieces 2a and 2b formed of plastic or the like mutually connected to each other. The cartridge case 2 is made of a hard case formed into a flat box shape by being joined to the cartridge case 2, and a disc-shaped recording medium 3 is housed inside the cartridge case. The cartridge case 2 has a center hole 4a and a head insertion hole 5 for exposing the hub 4 attached to the recording medium 3 to the outside.

Next, this disk cartridge 1 is provided with a write protector 6 that makes it impossible to write or erase information on the recording medium 3, and the write protector 6 is provided at a corner of the cartridge case 2. There is. That is, the upper and lower cover parts 2a and 2b have recesses formed on the inner surfaces of their corners to form guiding cavities 7, and at the same time, through holes 8 are formed at the positions where the cavities 7 are formed. and this through hole 8
By opening and closing the storage medium 3, it is possible to switch between a write-inhibited state in which writing or erasing of information on the recording medium 3 is impossible, and a state in which the prohibition is released. A slider 9 is installed in the cavity 7 to open and close the through hole 8. The slider 9 is the fifth
As shown in the figures and FIG.
By moving the inside, the shutter portion 11 is displaced between a state in which it covers the through hole 8 and a state in which it opens. In order to position the slider 9 in the opened/closed state and the closed state of the through hole 8 in this way, engaging protrusions 13, 13 are protruded from the outer surfaces of the legs 12, 12, and the hollow portions Positioning protrusions 14, 14 are provided on the side wall of 7 to protrude inward.

Furthermore, in FIGS. 1 to 3, reference numeral 15 indicates a storage box for storing the disk cartridge 1, and the storage box 15 is made of an elastic member such as plastic. And storage box 15
An engaging member 16 that engages with the slider 9 is protrudingly provided on the inner surface of the storage section, and the distance between the tip of the engaging member 16 and the inner surface of the storage box 15 on the side facing it is shorter than the width of the disk cartridge 1. It's summery. The engaging member 16 is disposed at a position where, when the disk cartridge 1 is inserted, it comes into contact with the operating knob 10 of the slider when the through hole 8 is open. The slider 9 can be engaged with the engaging member 16 not only when inserting the disc cartridge 1 with one side facing toward you, but also when inserting the disk cartridge 1 with the other side facing toward you. In order to make this possible, as shown in FIG. 3, the engaging members 16 may be provided one each at symmetrical positions.

On the other hand, even when the slider 9 is in the write-protected state, the cover part 2
The wall surfaces of the perforated portions of the through holes 8 of a and 2b and the portions of the slider 9 that face these are inclined surfaces 8a and 9a, respectively.
Due to these, a V-shaped recess is formed when the slider 9 is in this position. In FIG. 5, reference numerals 17a and 17b respectively indicate a light source and a phototube built into a recording and reproducing apparatus (not shown), and these constitute the detection means 17 for detecting the open/closed state of the through hole 8.

This embodiment is constructed as described above, and by attaching the disk cartridge 1 to the recording/reproducing device, information can be written to and read from the recording medium 3. There is. This magnetic disk cartridge 1 is provided with a write protector 6.
When the slider 9 constituting the slider 9 is in the position shown in FIG. 5 and the through hole 8 is open, writing is prohibited, which makes it impossible to write information to the recording medium 3 and erase the recorded contents. When the slider 9 moves upward from the above-mentioned state to a position where it covers the through hole 8, a write prohibition state is reached in which writing information to the recording medium 3 and erasing the recorded contents becomes possible. It will be switched to.
The opening/closing operation of the through hole 8 by the slider 9 is performed, for example, by grasping the operation knob 10 with fingers.
opening/closing is detected.

By the way, from the viewpoint of protecting the recorded contents of the recording medium 3, the write protector 6 should be set in a write-inhibited state at all times, and be switched to the inhibited state each time it is necessary to perform writing or erasing. It is preferable that you are able to do this.
Therefore, in the present invention, an engaging member 16 is provided protruding from the inner surface of the storage box 15, and for this reason,
For example, when the write protector 6 is in the inhibited state due to writing on the recording medium 3, etc., when the disk cartridge 1 is inserted into the storage box 15, the engaging member 16 first appears on the outer surface of the cartridge body 2. When they come into contact with each other, the storage box 15 is elastically deformed in a direction in which it slightly expands. Then, the disk cartridge 1 is stored in a predetermined amount storage box 1.
5, the shape of the storage box 15 is restored by the engagement member 16 fitting into the recess between the inclined surfaces 8a and 9a, as shown in FIG.
When the disk cartridge 1 is further pushed in from this state, the slider 9 is pushed by the engaging member 16 to open the through hole 8 and displace the write protector 6 so as to switch to the write inhibited state.

In this way, for example, even if the write protector 6 is in a write-protected state, by inserting the disk cartridge 1 into the storage box 15,
It is reliably and automatically switched to the write-protected state, and the recorded contents can be fully protected. in this case,
In the stored state, in order to protect the recording medium 3 of the disk cartridge 1, it is always stored in the storage box 15, so when it is removed from the storage box 15 and installed in the recording/playback device, the The protector 6 is always in a write-protected state.

Furthermore, when the magnetic disk cartridge 1 is stored, the engaging member 16 is fitted into the through hole 8, so that the disk cartridge 1 is stored in the storage box 15 in an extremely stable state. This prevents the disk cartridge 1 from escaping from the storage box 15 during handling, and the storage box 15 fully performs its function of protecting the recording medium 3.

[Effect of idea]

As described in detail above, the disk cartridge storage box according to the present invention puts the write protector in a write-inhibited state by the engagement member protruding from the inner surface of the storage box when the disk cartridge is stored in the storage box. Since it is configured so that it can be switched to , when the disk cartridge is removed from the storage box, unless the slider is moved again,
The write protector is always in a write-protected state, and can fully perform its original function of protecting recorded contents.
