DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a memory cover opening and closing device in a memory card insertion portion of various small electronic devices.

[0002]

2. Description of the Related Art In recent years, as multimedia-compatible products,
As the number of products equipped with a memory card increases, the size of the device is becoming smaller and smaller.
For this reason, it has become difficult to secure an area for the card cover for preventing the memory card from falling off and dust from entering the inside of the device.

[0003] Conventionally, in the case of a lid that opens and closes around a rotation axis near the center of the device body, when the lid is opened and a memory card is removed, a method of pressing a memory card removal button or the card itself is used. There is a so-called push-push method in which a memory card is pushed out, or a method in which a memory card is directly pulled out. However, in both cases, it is necessary to insert a finger into the recess after opening the lid, and to secure a planar area enough for the finger to enter,
A space for accommodating a structure for opening and closing the door is required, which is a great constraint in downsizing the device.

Hereinafter, a cover opening / closing device used in a conventional video camera will be described.

FIGS. 7 to 11 show a conventional lid opening / closing device. A method for removing a memory card will be described by taking the above-mentioned push-push method as an example. FIG.
(C) shows the opening / closing operation of the card cover when the memory card is inserted in the push-push system.

[0007] Reference numeral 17 denotes a video camera body, which is not shown, includes an image pickup unit for picking up an image of a subject therein, a microphone unit for inputting ambient sound, and a tape-shaped recording medium for recording video and audio signals obtained from the image pickup unit and the microphone unit. And a video signal recording / reproducing unit for reproducing the recorded signal.

A card cover 9 is provided on the side of the video camera main body 17 so as to be openable and closable. The card cover 9 is opened and closed when the memory card 7 is inserted and removed, and is closed to prevent dust and dust from entering the card holder 18 described later. In.

Reference numeral 12a denotes a knob, which is a video camera body 17;
The knob 12a is moved slidably in the direction of arrow k in FIG.
When the lock claw 12b shown in (b) and the lock claw 9a provided on the back surface of the card cover 9 are disengaged from each other, the card cover 9 becomes rotatable about the shaft 11 in the direction of arrow m. Then, the memory card 7 can be inserted into the card holder 18 fixed to the video camera body 17 in the direction of arrow n.

In the push-push method of this embodiment, the memory card 7 is held by inserting the memory card 7 into the card holder 18 in the direction of arrow p in FIG. By rotating the card cover 9 in the direction of arrow q, it is possible to return to the state of FIG.

FIGS. 8A to 8C show the opening / closing operation of the card cover when the memory card is ejected by the push-push method. At this time, the memory card 7 is stored in the card holder 18 and the memory card 7 shown in FIG.
It is in the state of. From this state, the knob 12a is moved to the position shown in FIG.
By moving the card cover 9 in the direction of arrow k, the card cover 9 rotates in the direction of arrow m and the memory card 7 can be taken out.

Thereafter, about 1.
When the memory card 7 protruding by 5 mm is pressed again by a finger in the direction of arrow p, the memory card 7 pops out by about 5 mm as shown in FIG. 8B, and is pinched by the finger as shown in FIG. ) Can be pulled out in the direction of arrow u.

The above is the description of the conventional operation for opening and closing the card cover 9 and inserting and ejecting the memory card 7.

FIGS. 9A and 9B show the relationship between the card holder 18 and the card cover 9. FIG.
2A, reference numeral 17a denotes a case unit constituting the video camera body 17, and a card cover 9 and a mechanism for rotating the card cover 9 are the case unit 1.
7a. Although a detailed description is omitted, the card holder 18 has a push / push mechanism in itself, and can be electrically connected to record or read video and audio signals on a memory card. It is inserted into a hole 17b provided in the case unit 17a.

FIG. 9B shows a state in which the card holder 18 is fitted to the case unit 17a. As shown, the card holder 18 and the card cover 9 are completely independent of each other.

FIGS. 10A and 10B show the structural relationship of the case unit 17a, the card cover 9, and a mechanism for rotating the card cover 9. FIG. In FIG. 10A, a hole 17c and a hole 17d are provided in the case unit 17a, respectively, and a knob 12a for releasing the fitting of the card cover 9 and a lock claw 12b are inserted into these holes, and It is slidably attached to the unit 17a.

The spring 10 is attached between the card cover 9 and the fixing plate 19 via a shaft 11.
Is always biased in the opening direction. FIG. 10B shows the opening and closing mechanism of the card cover 9 in more detail.
In FIG. 10B, reference numeral 21 denotes a card cover 9 and a spring 1.
0, a shaft 11 and a fixing plate 19, and the mechanism 21 is a case unit 17
a is fixed by screws 15 from one direction.

The slide piece 12 has a knob 12a and a lock claw 12b, and the lock claw 12b is
a moves in the same size and direction as slidably moves with respect to the case unit 17a, and engages or disengages with the lock claws 9a of the card lid 9. Slide piece 1
2 is fixed by screws 20 from one direction of the case unit 17a by a fixing bracket 13, and the slide piece 12 is always urged by a spring 14 in a direction to be fitted to the lock claw b of the card cover 9.

FIGS. 11A and 11B show details of the structure of the unit mechanism 21 shown in FIG. 10B. FIG.
10A is an enlarged view of the mechanism 21 in FIG. 10B, and FIG. 11B shows details of a component configuration of the mechanism 21.

In FIG. 11B, the shaft 11 is inserted into a through hole 9b provided in the card cover 9 and a through hole 19a provided in the fixing plate 19.
The card cover 9 is rotatably attached to the fixing plate 19 via the. A spring 10 is attached to the card cover 9 at the same time as the shaft 11 is penetrated, and the spring 10 is provided with an arm 10a and an arm 10b. The arm 10a sinks into a recess 9c provided in the card cover. , Arm 10b
Is in contact with the fixing plate 19, so that the card cover 9 is always
