Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door opening / closing device for various unit parts in an electronic device such as a personal computer.

[0002]

[Prior Art]

 The present invention generally incorporates a magnetic storage device such as a floppy disk driver (FDD) or a streamer unit in various electronic devices such as a personal computer, to which a floppy disk (FD) or streamer recording device is installed. When a cartridge cartridge is mounted, a structure is often used in which the opening / closing door at the front of the FDD and streamer unit is opened and the tape cartridge for FD or streamer is inserted.

In this case, when the opening / closing door covers the opening of the cabinet main body, the opening / closing door is pushed up toward the opening of the cabinet main body to cover the opening.

As an example thereof, as shown in Japanese Utility Model Laid-Open No. 194593/1990, the opening / closing door covers the opening of the cabinet body when the lid is applied.

[0005]

[Problems to be solved by the device]

 In the above-mentioned conventional example, it is difficult to make it flush with the front side of the front of the cabinet, and therefore, in the case of the slide type, it is closed at a position slightly retracted from the front side.

Therefore, the present invention provides a novel door opening / closing device for electronic equipment, which eliminates the above-mentioned drawbacks.

[0007]

[Means for Solving the Problems]

 According to the present invention, the guide groove provided in the cabinet body is provided with a linear portion in parallel with the front surface portion of the cabinet body, and further, a taper portion and a linear portion are continuously provided, and a guide pin is fitted into the guide groove. For example, the opening / closing door can be securely closed on the same plane as the front side of the cabinet.

[0008]

[Action]

 In the door opening / closing device for electronic equipment of the present invention, the front surface of the door can be set flush with the front side of the cabinet body when the door is closed.

[0009]

【Example】

 The present invention will be described with reference to the drawings. FIG. 1 is a front view of the device of the present invention, FIGS. 2 and 3 are cross-sectional views of the main parts showing the states of opening and closing the door in AA of FIG. 1, and FIG. It is a principal part perspective view from the back direction which shows a mechanism.

In the drawings, (1) is a cabinet body, (2) is a door, (3) and (4) are guide pins provided above and below the door, and (5) and (6) are the cabinets. Guide grooves (5) provided in the upper and lower parts of the main body include a first straight line portion (7), a taper portion (8) and a second straight line portion (9), and the guide groove (6). It has a straight portion (10) and a tapered portion (11). (12) is a door movement control device having a rack (13), a pinion (14) and an oil damper (not shown) inside, and (15) is an opening provided in the cabinet body.

Next, the operation of opening and closing the door in the present invention will be described. First, as shown in FIG. 1, the opening (15) provided in the cabinet body (1) is covered by the front side of the cabinet body. The structure is such that the door (2) can be moved upward on the back side. In this case, when the door (2) is pushed up from the fully opened state to the position shown in FIG. 2 from the fully opened state to cover the opening (15), the guide pin ( 3) moves upward from the first straight portion (7) to the tapered portion (8), and the guide pin (4) moves downward from the straight portion (10) to the tapered portion (11).

When the door (2) is further pushed upward, as shown in FIG. 3, the upper guide pin (3) is guided to the second straight line portion (9), and the door (2) is moved to the cabinet main body ( It is set flush with the front surface of 1).

In the above-mentioned configuration, the illustrated example shows movement in the vertical direction, but if necessary at the upper position, a locking claw or the like is provided on the upper part of the cabinet body side, and the above locking is performed on the upper end of the door. By providing a locking hole for locking the claw, the door is securely held at the position shown in FIG.

Next, when the door (2) is moved downward after the above operation, the guide pin (3) moves the door (2) from the second linear portion (9) to the tapered portion (8) in the state of FIG. ) And set it to the state shown in FIG. 2, the door (2) will move downward due to its own weight, and the lower part shown by the broken line will move further downward through the intermediate position shown in FIG. The opening can be fully opened.

Here, when the door (2) is locked by the locking means at the upper side, when it is moved downward due to its own weight, the door (2) falls at once without any buffer mechanism such as friction means. Therefore, if a damper mechanism is installed on the back side of the door (2) and a rack (13) is installed on the cabinet body side as shown in FIG. 4, the pinion (14) that meshes with the rack (13) will allow smooth operation. The door (2) moves downward.

The rotating shaft of the gear is connected to a damper mechanism such as an oil damper, and has a cushioning function when the door (2) moves downward due to its own weight.

[0017]

[Effect of the device]

 According to the cabinet door opening / closing device of the present invention, the guide groove for guiding the upper pair of pins provided on the door side is provided to the opening of the cabinet main body when the lid is closed by the opening / closing door. The first straight line portion, the tapered straight line portion, and the second straight line portion are continuously provided to each other, and when the door is closed, the door has a structure in which the opening is pushed out to the position where the opening is completely covered. Since the front surface and the front surface of the door are flush with each other, the mechanism has a large lidding function and is extremely superior in appearance. The present invention is designed to open and close a door such as a disk driver in an information device that requires various opening and closing devices. If it is used in a device, the effect will be great.
