Abstract

(57) [Summary] [Purpose] In an electronic device that has multiple openable doors, the door closing order is regulated so that the doors are closed in a certain order, and the doors are damaged due to contact between the doors. To improve reliability. [Structure] An electronic device housing is provided with a sequence mechanism 3 that regulates a closing order of a door 1 and a door 2. The mechanism 3 is provided with a lock stopper and a stopper. When the upper door 1 is closed, the stopper slides to unlock the lock stopper, and the door 2 can be closed. On the contrary, when the door 2 is closed and then the door 1 is closed, the door is locked by the stopper.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing structure for an electronic device having a plurality of openable and closable doors, and more particularly to a housing structure for an electronic device which regulates a closing order of the respective doors.

[0002]

2. Description of the Related Art Conventionally, in an electronic device, when there are two doors, an upper door 7 that opens and closes in the vertical direction and a lower door 8 that opens and closes in the horizontal direction, as shown in FIG. Side door 8
3, the upper door 7 and the lower door 8 overlap so that no foreign matter is inserted through the gap and the inside cannot be seen. Therefore, if the order in which the upper door 7 and the lower door 8 are closed is not regulated, the mating portion of the upper door 7 and the lower door 8 may come into contact with each other. A related device of this kind is, for example, Japanese Utility Model Publication No. 1-24947.

[0003]

In the above-mentioned prior art, since the door closing operation sequence is not regulated, the doors may come into contact with each other depending on the door closing operation sequence and the doors may not be closed. Furthermore, there is a problem that the door is damaged or damaged. An object of the present invention is to improve such a problem, and in an electronic device having a plurality of doors that can be opened and closed, it is possible to regulate the closing order of the doors and improve the reliability of the device. To provide the body structure.

[0004]

In order to achieve the above object, the housing structure of an electronic device according to the present invention is an electronic device having a plurality of openable / closable doors, and is closed when the plurality of doors are closed. It is characterized in that a means for mechanically controlling the sequence (a sequence mechanism having the locking stopper 4, the stopper 5 and the spring 6 in FIG. 1) is provided.

[0005]

In the present invention, if the doors are closed in any order other than the predetermined order, the doors are locked by the locking stopper of the sequence mechanism, so that the closing order of a plurality of doors can be regulated. This prevents the doors from touching each other,
The doors can be reliably closed in a fixed order, improving the reliability of the device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a door closing order regulation mechanism in one embodiment of the present invention, and FIG. 4 is a perspective view of an electronic device having a plurality of doors in one embodiment of the present invention. In FIG. 4, 1,
Reference numeral 2 is a door of the electronic device casing, and 3 is a sequence mechanism, and the door 1 is closed first and the door 2 is closed later. As shown in FIG. 1, the sequence mechanism 3 is composed of a lock stopper 4, a stopper 5, and a spring 6 that constantly urges the lock stopper 5 to operate toward the lock side.
In this embodiment, when the upper door 1 is closed, a load is applied in the direction of arrow A, and the stopper 5 causes the locking stopper 4 to move.
When the stopper 5 is locked against rotation in the direction of arrow C, the stopper 5 is unlocked by sliding the stopper 5 in the direction of arrow B. Further, when the lower door 2 is to be closed first, the lock of the locking stopper 4 acts so that the lower door cannot be closed. Therefore, the order of closing the doors is restricted so that the upper door 1 is closed and the rear lower door 2 is closed. Even if the number of doors is 3 or more,
It goes without saying that the order can be similarly regulated only by increasing the number of sequence mechanisms for regulating the door closing order. According to this embodiment, by providing the door closing order regulation mechanism, there is an effect that a plurality of doors can be closed in a fixed order.

[0007]

According to the present invention, in an electronic device having a plurality of doors that can be opened and closed, the doors can be closed in a fixed order by regulating the closing order of the doors, and the contact between the doors can be further improved. Can prevent the door from being damaged due to contact and improve the reliability of the device.
