Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover device for covering a small electronic device such as a mobile phone as a recording medium for opening and closing a memory card.

[0002]

2. Description of the Related Art In recent years, in various small electronic devices, as a result of miniaturization and high functionality, a small card-shaped memory card can be attached / detached in order to share data with other electronic devices. It has been used as a medium. Therefore, it is necessary to provide a cover at the memory card inlet part of the housing for attaching and detaching the card, for the purpose of improving the quality by improving the design and protecting the inside of the device and the memory card. However, in the conventional card lid opening and closing device that locks and unlocks the lid by sliding the claw, the opening angle of the lid is made large to ensure the operability of the memory card, and the gap between the lid and the main body. Since it is difficult to make both of them smaller because of conflicting requirements, a structure that solves the problem has been required. The conventional card lid opening / closing device used for such a video movie will be described below.

First, a conventional card lid opening / closing device will be described with reference to FIGS. In FIG.
The video movie 50 has an image pickup section for picking up an image of a subject inside, a microphone section for inputting ambient sound, and video and audio signals obtained from the image pickup section and the microphone section recorded on a recording medium such as a tape and recorded. And a video signal recording / reproducing unit for reproducing the signal. The card lid opening / closing device shown in FIG. 11 includes a card lid 58 that is opened / closed when the memory card 64, which is a card-shaped recording medium, is inserted / removed. The lock piece 61 is slidably attached to the card lid 58. By moving this lock piece 61 in the direction of arrow h in FIG. 58 is the arrow j in FIG.
11C, the memory card 64 is ready to be inserted in the direction of arrow k as shown in FIG.

Next, referring to FIGS. 12 and 13, the structure of the conventional card lid opening / closing device will be described. 12
In (A), the opening / closing spring 59 is inserted into the recess 51 of the card lid 58 in the direction of arrow m, and the lock piece pressing spring 60 is inserted into the recess 52 of the card lid 58 in the direction of arrow l. In FIG. 12B, the lock piece 61
Is inserted into the hole 58b for the spindle from the direction of the arrow n, and then inserted into the lock piece pressing spring 60 arranged in the recess 52. Axis 62
Is inserted into the support hole 58a from the direction of the arrow p, and is inserted into the opening / closing spring 59 provided in the recess 51 to be assembled as a card lid opening / closing device.

The card lid opening and closing device thus assembled is assembled to the card holder 63 as shown in FIG. The card holder 63 is formed with a support shaft hole 63a into which the shaft 62 is inserted. The card 58 is inserted into the support shaft hole 63a from the direction of the arrow q.
The card lid 58 is rotatably attached to the card holder 63 by processing both ends of the card with caulking or the like. Further, the card holder 63 is formed with a hook hole 63b so that when the card lid 58 is closed with respect to the card holder 63, it can be engaged with the tip of the lock piece 61. .

Next, with reference to FIG. 14 and FIG. 15, the structure of the conventional card lid opening / closing device configured as described above will be described. FIG. 14A shows a state in which the card lid 58 is closed with respect to the card holder 63. Here, FIG.
As shown in FIG. 4B, the card lid 58 is provided with the opening / closing spring 5.
A load is applied in the rotational direction, which is the arrow s direction ((C) of FIG. 14) by the biasing force of 9, but in this state, as shown in (B) of FIG. Since the lock piece 61 is pressed in the direction of the arrow t, the lock piece 61 engages with the hook hole 63b and the card lid 58 does not rotate.

FIG. 15 shows a state in which the card lid 58 has moved with respect to the card holder 63. As shown in FIG. 15A, when the lock piece 61 is moved in the direction of arrow r,
As shown in FIG. 15B, the lock piece 61 is disengaged from the hook hole 63b. Then, the opening / closing spring 59
15C, the card lid 58 rotates about the shaft 62 in the direction of the arrow s as shown in FIG. 15C, opens to the position where the video movie body 50 and the card lid 58 come into contact with each other, and the memory card 64 is opened. The card holder 63 can be attached to and detached from the card holder 63.

Next, with reference to FIG.
A conventional card lid opening / closing device as described in Japanese Patent No. 322519 will be described. This card lid opening and closing device is intended to solve the problem that the opening and closing angle of the card lid is small because the gap between the card lid and the main body of the video movie is narrow, and it is difficult to insert and remove the memory card. . In FIG. 16, the card lid 7
1 is a first position (A in FIG. 16) that covers the opening 75b of the card holder 75, and the first position where the card lid 71 is moved in the direction perpendicular to the direction in which the memory card 76 is inserted. 2 position ((B) of FIG. 16) and the card lid 71
Is rotated from the second position to the third position ((D) in FIG. 16) for opening the opening 75b, thereby removing the card cover 7
As a result, the opening angle 1 can be sufficiently set, and the memory card 76 can be easily inserted or removed.

[0009]

However, in the configuration of the above-described conventional card lid opening and closing device for video movies, as shown in FIG. 15, since the gap B between the card lid 58 and the video movie 50 is narrow, the card lid is closed. There is a problem that the opening angle of 58 is small and it is difficult to insert and remove the memory card 64. In particular, since the amount of the memory card 64 protruding from the card holder 63 is small as shown in FIG. 15, there is a problem in that when the memory card 64 is taken out from the card holder 63, the memory card 64 is difficult to grip and difficult to take out. If the gap B between the card lid 58 and the video movie main body 50 is widened, foreign matter may enter the interior through the gap B.

Further, in the conventional card lid opening / closing device as shown in FIG. 16, a card lid for covering the memory card inlet portion of the housing is provided by a spindle arranged in a card holder mounted on a printed wiring board. It is a constitution to support,
Since the card lid is incorporated into the housing together with the printed wiring board, variations may occur during assembly, which may impair the external function. Further, when mounting the card holder on the printed wiring board, there is a problem that it is difficult to handle reflow (automatic mounting) depending on the material of the card lid.

The present invention has been made in order to solve the above-mentioned conventional problems. With a simple structure, a memory card can be easily attached / detached, and the appearance function due to variations in assembly is not impaired. Further, the present invention provides a cover device for a small electronic device having a simple structure and easy to assemble.
