Abstract

PURPOSE:To minimize the displacement quantity of a loading means and to thin a device by amplifying the displacement quantity of the loading means and transmitting it to a slide shutter. CONSTITUTION:When a cartridge 2 is inserted into a cassette inserting/ discharging opening 3, the disc cassette 2 is automatically fetched to a prescribed position by a loading means 5, next, the loading means 5 is turned and displaced by a movable means and the optical disk is fitted to an information processing means. On the other hand, the displacement action of the loading means 5 is amplified and transmitted to a slide shutter 11 through a shutter operating means 14 the slide shutter is closed. Since the displacement quantity is amplified and transmitted to the slide shutter like this, the displacement quantity of the loading means can be minimized and the device can be thinned.

Description

Detailed Description of the Invention [Objective of the Invention] (Industrial Application Field) The present invention provides information processing for an information storage disk such as an optical disk that has a built-in information processing means and a loading means and is housed in a disk cassette. The present invention relates to an improvement in a shutter device that opens and closes a cassette insertion/ejection opening of an information processing apparatus that performs processing.

(Prior Art) Usually, an information processing device using an optical disk as an information storage medium;
That is, an optical disk device is provided with a shutter device that opens and closes a cassette insertion/ejection port for inserting/ejecting a disk cassette containing an optical disk, and prevents foreign matter such as dust from entering the device through the cassette insertion/ejection port. The structure is such that other disk cassettes are not inserted while the disk cassette is being loaded.

Conventionally, there is a shutter device of this type as shown in FIG. This is located at a constant downward position by a spring d, facing a cassette insertion/ejection opening C formed on a part a of the front cover of the apparatus main body for inserting and removing a disk cassette b.
That is, a slide shutter e is provided which is biased in a direction to always open the cassette insertion/ejection port C, and an L-shaped portion formed on the lower end side of the slide shutter e is provided to protrude toward the free end side of the loading means f. The structure is such that it is placed on a hook g.

The slide shutter e is opened and closed in accordance with the rotational displacement movement of the loading means f about the shaft h.

(Problems to be Solved by the Invention) As described above, in the conventional shutter device, the slide shutter e is moved by the hook g attached to the free end side (cassette insertion/ejection port side) of the loading means f by the displacement operation of the loading means f. Since opening and closing are performed, a displacement operation corresponding to at least the thickness of the disk cassette b is required, making it impossible to make the device thinner. Furthermore, even if the disc cassette b is not in the device, the position where the slide shutter e is closed is the initial position of the loading means f, so when loading the disc cassette b, you must first operate the input means such as a switch (not shown). Loading means f to cassette insertion/ejection port C
It is necessary to open the slide shutter e by this displacement operation, which is cumbersome to operate and takes time to load. Furthermore, there is a problem in that it is not possible to tell whether or not the disk cassette b is loaded in the apparatus just by looking at the cassette insertion/ejection opening C when the slide shutter e is closed.

The present invention has been made based on the above circumstances, and its purpose is to reliably open and close the disk cassette insertion/ejection opening even if the amount of displacement of the loading means is small, to make the device thinner, and to facilitate switch operation, etc. The disc cassette can be directly inserted into the cassette insertion/ejection port without having to do so, improving operability and shortening the loading time. Moreover, it is possible to check whether a disc cassette is being loaded into the device by looking at the cassette insertion/ejection port that is closed by the shutter. The object of the present invention is to provide a shutter device with good operability that allows checking whether the

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above object, the present invention has a built-in information processing means and a loading means and processes information on an information storage disk housed in a disk cassette. A shutter device for opening and closing a cassette insertion/ejection port of an information processing device, the shutter device comprising: a slide shutter provided slidably in a direction perpendicular to a disk cassette insertion/ejection direction to open and close the cassette insertion/ejection port; Amplifying and transmitting the amount of displacement of the loading means, opening the cassette insertion/ejection opening when the loading means is at the disk cassette insertion/ejection position, and closing the cassette insertion/ejection opening when the loading means is at the position where the disk cassette is attached to the information processing means. The disk cassette is configured to include a shutter actuating means for moving the slide shutter to allow the disk cassette to be inserted, and a rotary shutter that is biased to always close the cassette insertion/ejection opening and is opened by the insertion operation of the disk cassette.

(Function) In other words, with the above configuration, the present invention amplifies the amount of displacement of the loading means and transmits it to the slide shutter, so the amount of displacement of the loading means can be reduced, and the device can be made thinner. becomes possible. Also,
The initial loading position of the loading means is opposite the cassette insertion/ejection port, and the cassette insertion/ejection port is closed only by a rotating shutter that opens when the disc cassette is inserted, improving operability and loading. It becomes possible to shorten the time. In addition, the rotary shutter closes the cassette insertion/ejection opening when the disk cassette can be loaded, and the slide shutter closes the cassette insertion/ejection opening while the disk cassette is being loaded. Even if an attempt is made to insert another disk cassette into the cassette, it can be mechanically blocked.

(Example) Hereinafter, one example of the present invention will be described with reference to FIGS. 1 to 3.

FIG. 2 shows an information processing device incorporating the shutter device of the present invention and a disk cassette used therein.

In the figure, reference numeral 1 denotes the main body of an information processing device.A cassette insertion/ejection opening 3 for inserting and removing a disk cassette 2 is formed in a front cover portion 1a of the main body 1, and information is stored in the main body 1. The processing means 4, the loading means 5, a control mechanism section (not shown), etc. are accommodated therein.

When the cartridge 2 is inserted into the cassette insertion/removal port 3, the disk cassette 2 is automatically taken in to a predetermined position by the loading means 5. At this time, the front case 2a and rear case 2 of the disk cassette 2
b is automatically opened, and the optical disc 6 as an information storage disc in the disc cassette 2 is loaded into the information processing means 4 with a part thereof exposed. Note that the configuration of such an information processing device is well known, so a detailed explanation will be omitted.

Also, a part of the front cover 1a in which the cassette insertion/ejection port 3 is formed is shown.
It also serves as a control panel, and is provided with operation/display means 7.

Further, a shutter device 10 for opening and closing the cassette insertion/ejection opening 3 is provided on the back side of the front cover portion 1a, as shown in FIG. The structure includes two shutters, 12 and 12.

The slide shutter 11 is attached to be slidable via a guide means (not shown) in a direction (direction of arrow B) perpendicular to the direction of insertion and removal of the disk cassette 2 (direction of arrow A) in order to open and close the cassette insertion/ejection opening 3. . This slide shutter 11 is integrally molded with a support tongue portion 11a that projects horizontally from the lower end side.
One end of a tension spring 13 serving as a biasing body is connected to. Due to the biasing force of the tension spring 13, it is always biased downward, that is, in the direction of opening the cassette insertion/ejection port 3.

The slide shutter 11 is linked to the movement of the loading means 5 via a shutter actuating means 14, which will be described later. position), open the cassette slot 3 and insert the disc cassette 2.
The position where is installed in the information processing means 4 (solid line position in Figure 1)
The cassette insertion/ejection port 3 is closed when the cassette is in the position.

The shutter actuating means 14 has one end 15a in contact with the lower surface of the loading means and the other end 15b in contact with the lower surface of the support tongue portion 11a of the slide shutter 11, and It is constituted by a link 15 supported swingably in the C direction. Also, the distance from one end 15a of the link 15 to the support shaft 16, e
l is the distance 14J2 from the other end 15b to the support shaft 16
2 (, L'+ >, j'2), and the amount of displacement of the loading means 5 is amplified and transmitted to the slide shutter 11. Even if the amount of displacement is small, it can be opened and closed reliably.

Further, the rotary shutter 12 is connected to the cassette insertion/ejection opening 3.
It is rotatable in the direction of the arrow around a shaft 7 horizontally suspended along the upper opening edge, and
A torsion spring 18 serving as a biasing body provided on the pivot end side is biased to always close the cassette insertion/ejection port 3. Then, it is opened by inserting the disk cassette 2.

Further, the sliding shutter 11 and the rotary shutter 12 are arranged so that the portions visible from the cassette insertion/ejection opening 3 are colored in different colors, or are displayed with a display indicating that the disk cassette 2 is 9 missing.

As shown in FIG. 3<a>, the loading means 5 is located at the position where the disk cassette 2 is loaded, facing the cassette insertion/ejection port 3 (upper limit position). At this time, the slide shutter 11 is displaced downward by the biasing force of the tension spring 13, and the cassette insertion/ejection opening 3 is closed only by the rotary shutter 12.

Next, as shown in FIG. 3(b), when the disk cassette 2 is inserted into the cassette insertion/ejection opening 3, the rotary shutter 12 is pushed away by the disk cassette 2 and opened. When the disk cassette 2 is inserted by a predetermined amount into the loading means 5, the loading means 5 automatically takes in the disk cassette 2 to a predetermined position. At this time, the front case 2a and rear case 2b of the disk cassette 2 are automatically opened to expose a part of the optical disk 6 inside the disk cassette 2.

Next, as shown in FIG. 3(C), the loading means 5 is rotationally displaced by a movable means (not shown) to the position shown by the solid line, and the optical disk 6 is loaded into the information processing means 4.

On the other hand, the displacement operation of the loading means 5 is amplified and transmitted to the slide shutter 11 via the shutter actuating means 14, and the slide shutter 11 is brought into a closed state. In addition,
At this time, the lower end 12a of the rotary shutter 12 is in a state of being cut over the upper surface of the loading means 5, and is maintained in an open state.

Furthermore, when taking out the disk cassette 2 from the main body 1 of the apparatus, the slide shutter 1 is moved by the reverse operation of the loading operation described above.
1 is lowered to open the cassette insertion/ejection port 3, and when the disk cassette 2 is removed, the rotating sleeve 12 closes the cassette insertion/ejection port 3.

In this way, in the present invention, since the amount of displacement of the loading means 5 is amplified and transmitted to the slide shutter 11, the amount of displacement of the loading means 5 can be reduced, and the device can be made thinner. . Further, the initial loading position of the loading means 5 is located opposite the cassette insertion/ejection port 3, and the cassette insertion/ejection port 3 is closed only by the rotary shutter 12, which opens when the disk cassette 2 is inserted. , it is possible to improve operability and shorten loading time. Also, when the disk cassette 2 is ready to be loaded, the rotary shutter 12 closes the cassette insertion/ejection opening 3, and while the disk cassette 2 is being loaded, the slide shutter 11 closes the cassette insertion/ejection opening 3, so by looking at the shutters 11 and 12, Not only can you check the loading status, but also allow you to load another disc cassette 2 while loading.
Even if an attempt is made to insert it, it can be mechanically blocked.

Further, since the slide shutter 11 and the rotary shutter 12 are operated by the displacement operations of the disk cassette 2 and the loading means 5, a dedicated drive source is not required.

In the above-mentioned embodiment, the shutter actuating means 14 for transmitting the displacement operation of the loading means 5 to the slide shutter 11 is arranged in a link 15 whose rotational position is shifted from the intermediate position.
Although the present invention is not limited to this configuration, any configuration may be used as long as the amount of displacement of the loading means 5 can be amplified and transmitted to the slide shutter 11.

In addition, it goes without saying that the present invention can be modified in various ways without departing from the gist thereof.

[Effects of the Invention] As explained above, according to the present invention, since the amount of displacement of the loading means is amplified and transmitted to the slide shutter, the amount of displacement of the loading means can be reduced, and the device can be made thinner. becomes.

In addition, the initial loading position of the loading means is opposite to the cassette insertion/ejection opening, and the cassette insertion/ejection opening is closed only by a rotary shutter that opens when the disk cassette is inserted, improving operability. This makes it possible to shorten reload time. In addition, the rotary shutter closes the cassette insertion/ejection opening when the disk cassette can be loaded, and the slide shutter closes the cassette insertion/ejection opening while the disk cassette is being loaded. It is possible to provide a shutter device that can mechanically block an attempt to insert another disk cassette into the disk cassette.
