Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a cassette type dehumidifier, in which a dehumidifying agent is stored in a cassette having the same shape as an existing disc-shaped record carrier cassette. It is designed to dehumidify cassettes and disk drivers.

(Problems to be solved by the conventional technology and device) For example, since a cassette containing a disk-shaped record carrier such as a CD, an optical disk, and a floppy disk tends to be covered with moisture, mold is likely to occur.

Conventionally, as a means for preventing the formation of mold, for example, the cassette is stored together with the dehumidifying agent in an appropriate box or drawer.

However, the means for storing the cassette in a box or drawer is messy and easily damaged, and it is not good for tidying up and appearance, and it is difficult to reliably dehumidify individual cassettes. There was a problem. Also, if moisture is trapped inside the disk driver in which the cassette is set, it will corrode the equipment and cause a short circuit.

Therefore, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a dehumidifier that can advantageously dehumidify a cassette of a disk-shaped record carrier or a disk driver.

(Means for Solving the Problems) For this purpose, the present invention comprises a cassette 1 having the same shape as the existing cassette C of a disk-shaped record carrier, and at least one of a front case 1a and a back case 1b constituting the cassette 1. A ventilation hole is provided in one of the cases 1a and 1b, which is provided with a storage chamber 8 in which the dehumidifying agent 11 is stored and which allows air inside and outside the cassette 1 to flow therethrough.
12 is formed on the surface of the cassette 1 facing the storage chamber 8.

(Operation) In the above configuration, the dehumidifier A is connected to the disk driver B.
, The inside of the disk driver B is dehumidified. Further, the dehumidifier A is dehumidified by arranging the dehumidifier A in the accommodating case D or a magazine together with the cassette C accommodating the disk-shaped record carrier.

(Embodiment) Next, an embodiment of the present invention will be described by taking a dehumidifier for a floppy disk as an example.

FIG. 1 is a perspective view of the cassette type dehumidifier A, and FIG. 2 is an exploded perspective view of the cassette type dehumidifier A, which is the main body of the dehumidifier A.
Is formed into a thin box shape by joining the front case 1a and the back case 1b. The outer shape of the cassette 1 is the same as that of an existing floppy disk cassette, and openings 3 and 4 are opened in the upper portions of both cases 1a and 1b, and a shutter 5 slides in the openings 3 and 4. It is installed freely. Further, a circular opening 6 is formed in the center of the front case 1, and a plurality of partitioning portions 7 are formed in a rib shape on the inner surface thereof to provide a plurality of storage chambers 8. A partition 9 corresponding to this is also formed on the inner surface of the back case 2.

Reference numeral 11 is a powdery or granular dehumidifying agent stored in the storage chamber 8, and front and back cases 1a and 1b are provided with ventilation holes 12 for circulating air inside and outside the cassette 1,
A filter 13 is lined on the inner surface of each storage chamber 8 so that the dehumidifying agent 11 does not leak out of the cassette 11 from the storage chamber 8 (see also FIG. 3). The partition 7 reinforces the cases 1 and 2 and divides the moving space of the dehumidifying agent 11 into small parts, and prevents the dehumidifying agent 11 from moving around in the cassette 11 and hitting each other to generate dust. As the filter 13, for example, a high-density polyethylene nonwoven fabric (for example, DuPont's product name Tyvek 1073) or Japanese paper, which has a very fine grain and can prevent the powdery dehumidifying agent 11 from leaking,
Moreover, a material having sufficient air permeability is selected. Further, as the dehumidifying agent 11, strong acidic agents such as calcium sulfate that retain crystal water and deliquescent agents such as calcium chloride that easily damage the cassette 1 should be avoided. Natural porous materials such as natural zeolite and clay, and synthetic porous materials such as molecular sieve and silica gel are preferable.

Reference numeral 15 is an indicator label, which is visible from the circular opening 6 and is hard to be damaged by hitting objects.
It is attached to the center of 1b. This label 15 is made of a material that discolors when it contains water.For example, in the case of cobalt chloride, when it contains water, it changes color from blue to pink or white, so that the dehumidifying agent 11 has a hygroscopic capacity. You can see what you lost. Reference numeral 16 is a coating agent, which is made of a material having water permeability such as a polyester film.

The dehumidifier A is as described above, and as shown in FIG. 4, the dehumidifier A is set in the disk driver B to dehumidify the inside. Further, as shown in FIG. 5, a storage case D together with an existing floppy disk cassette C is provided.
If the cassette C is stored in, the case D can be prevented from being dehumidified and the cassette C can be prevented from being moldy. When the moisture absorption effect is reduced after long-term use, it can be regenerated by exposing it to sunlight or heating it in a microwave oven. Of course, the front and back cases 1a and 1b may be opened and closed, and the dehumidifying agent may be exchanged.

(Embodiment 2) In FIG. 6, the front and back cases 1a and 1b are cut off except for the lattice portion 31, a ventilation hole 32 is largely opened, and a filter 33 is attached to the surface thereof. The shutter 5 is not attached to this device. in this case,
If a plate-shaped dehumidifying agent in powder or powder form is pressed and sintered, the front and back cases 1a and 1b can be omitted, the structure can be simplified, and dust can be generated. Can also be reduced.

In addition, as shown in FIG. 7, four storage chambers 41 independent from each other are provided, and a label 43 for sealing is attached to the surface of the filter 42. Therefore, each time the dehumidifying capacity of the dehumidifying agent in each storage chamber 41 is lowered, each label 43 may be peeled off one by one in order, or in the case of high humidity, a plurality of labels 43 should be peeled off at the same time. May be used.

Further, in the structure shown in FIG. 8, the indicator 15 is attached to the slide portion of the shutter 5,
You can see the indicator 15 by opening.

Further, in the structure shown in FIG. 9, the partition part 45 is formed in a spiral shape, and this partition part 45 also has the same operation as the partition part 7.

(Effects of the Invention) As described above, the present invention is composed of the cassette 1 having the same shape as the cassette C of the existing disk-shaped record carrier, and at least one of the front case 1a and the back case 1b forming the cassette 1. Storage case 8 containing dehumidifying agent 11 in cases 1a and 1b
And the ventilation hole 12 for circulating the air inside and outside the cassette 1 is formed on the surface of the cassette facing the storage chamber 8 to form the cassette type dehumidifier A. The disk driver B and the cassette C housed in the housing case D can be dehumidified by the same handling as the carrier cassette C.
