Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a flexible magnetic disk drive device used in word processors, personal computers, and the like.

[Conventional technology]

Conventional flexible magnetic disk drive devices (hereinafter referred to as FDD devices) have a flexible magnetic disk drive (hereinafter referred to as FDD device) inserted into the insertion slot provided in the front bezel.
(referred to as FD) and push it to the specified position.
When the clamp lever is lowered 90 degrees, the FD is held against the spindle hub by the collector, and when the power is turned on, the FD becomes head loaded.

[The problem that the idea aims to solve]

Recent FDD devices are becoming larger in capacity,
High density media are being used more frequently. Since the magnetic coating film of this medium is thinner than that of conventional media, it is easily damaged by small dust particles, which may adversely affect data reading and writing.

In addition, due to the social situation of so-called OA, it is increasingly being used in places with poor environments.

However, the insertion port in conventional FDD devices is
Some models that use large FDs have their doors closed during operation, but none of them
The FDD equipment is also open when operation is stopped, making it easy for dust to enter.

Therefore, there is a need for dustproof measures that are easy to use.

Therefore, this invention has a function that automatically closes the FD insertion slot not only during operation but also when stopped.
Furthermore, the purpose is to provide an FDD device that has a simple structure and is easy to use.

[Means to solve the problem]

In order to achieve this purpose, this invention has the following structure.

That is, the FDD device according to this invention has upper and lower shutters movable up and down along the insertion opening of the front bezel, and the shutters are compressed by a relatively weak closing spring, and the opening side edge of the shutter is pressed by a relatively weak closing spring. Tapered, rounded, etc. guide parts are provided on the inside and outside so that the insertion port can be closed at all times with a shutter, and at the same time, the FD can be inserted and ejected using the hop-up device without any trouble.

〔Example〕

An embodiment of this invention will be described with reference to the drawings.

FIG. 1 shows a front view of the embodiment, and 1 is a front bezel in which a slit-shaped FD insertion opening 2 is provided. A push-in hole 3 is provided in the center of the FD insertion port 2, which is large enough for a finger to pass through.

FIG. 2 is a rear view of the front bezel 1, showing two pairs of pins 4, 4 installed on the back of the front bezel 1,
Upper and lower shutters 6, 7 are respectively attached to the upper and lower shutters 5, 5 so as to be able to rise and fall, and each shutter 6, 7 is pressed inward by four relatively weak springs 8, respectively.

The shutters 6 and 7 in this embodiment
As shown in FIG. 3, the side edges of the opening side are rounded 9 and 10 for smooth sliding. Note that 11 in the figure is an E-ring for fixing the shutters 6 and 7 to the pins 4 and 5.

Since the configuration is as described above, the shutter 6,
Since 7 is always pressed by springs 8, 8, it is always closed except when the FD is inserted or ejected, which will be described below, to prevent dust from entering.

The FDD device according to this invention has shutters 6 and 7.
is pressed by relatively weak springs 8, 8, and its opening side edges are rounded 9, 10, so
As shown in Figure 3, when the FD12 is inserted in the direction of the arrow, the upper and lower shutters 6 and 7 are pushed open by the force in the shutter pushing and spreading direction of the force in the FD movement direction, allowing the FD12 to be pushed in easily. . Also, when the hop-up device is activated, it pops out to the FD without any problem as before.

In the embodiment shown in FIGS. 1 to 3, radiuses 9 and 10 are attached to the side edges of the shutters 6 and 7 on the opening side. The dust-proofing effect can be improved by attaching them to the inside and outside, or by using an interlocking type as shown in Fig. 4b.

Claims (1)

[Scope of utility model registration request] Upper and lower shutters 6 and 7 are provided along the insertion opening 2 of the front bezel 1 so as to be able to rise and fall, respectively, and these shutters are pressed by a relatively weak closing spring 8, and the inner and outer edges of the opening side edges of the shutters 6 and 7 are A flexible magnetic disk drive device characterized in that a guide portion such as a taper or a radius is attached to the flexible magnetic disk drive device.
