Description

  The present invention relates to an opening and closing mechanism for opening and closing a main body opening having an internal connection terminal on a main body side to which terminals of an external device or a storage medium are connected.

In recent years, various electronic devices that can be easily carried and used have been developed and widely used. Examples of such portable products include mobile communication devices such as mobile phones, PHSs (Personal Handy phone Systems), and PDAs (Personal Digital Assistance), as well as portable navigations, electronic notebooks, notebook personal computers, and digital devices. Cameras and the like are known.
Such portable products require data communication with other electronic devices via a cable or direct data communication with a storage medium such as a memory stick or memory card. Connection terminals are provided at appropriate places on the main body side.

FIG. 7 illustrates a mobile phone as an example of a mobile product.
The mobile phone has a power supply, various electronic circuits, and the like built in the main body 1. On the operation surface of the main body 1, a display unit 2 such as a liquid crystal panel, various operation switches (buttons) 3, a microphone and a speaker (not shown) are provided. Reference numeral 4 in the drawing denotes an antenna projecting from the main body 1, 5 denotes a connection terminal opening cap that covers the main body opening for the charging terminal / external device connection terminal, and 6 denotes a main body opening for the storage medium connection terminal. The storage medium opening cap 7 is an earphone opening cap that covers the opening for the earphone connection terminal.

  The connection terminal opening cap 5, the storage medium opening cap 6, and the earphone opening cap 7 are members formed of, for example, resin, rubber, or the like into substantially the same shape as each opening. These caps 5, 6, and 7 are attached for the purpose of preventing foreign substances such as dust from entering the openings, and are fitted so that the user can manually attach and detach them as necessary. One end of each of the caps 5, 6, and 7 is locked to the main body 1 so as not to be lost even when the cap is removed from the opening.

  Also, regarding the dustproof of the opening for the storage medium connection terminal, for example, when the storage medium is a memory card, in order to prevent external dust from entering the card adapter from the memory card insertion slot in a normal state, the memory card insertion slot is used. It has been proposed to provide a dustproof member (resistance member) having a slit in the nonwoven fabric between the card adapter and the card adapter. (See, for example, JP-A-2002-150225 (page 3, FIG. 1 and FIG. 2))

As described above, in a portable product such as a cellular phone, a cap or a dustproof member is conventionally attached to prevent foreign matter such as dust from entering through openings formed in the main body for various connection terminals. I have.
However, in the structure in which the opening is covered with a cap made of rubber or the like, since a small cap attached in a fitted state is manually attached and detached, there is a problem in operability in addition to the fact that the locking portion and the like are easily damaged. In particular, since damage to the locking portion leads to loss of the cap itself, measures are required.

On the other hand, in the configuration in which the dustproof member is provided, the slit is always opened when the memory card is not used, and although the operability is superior to the above-described cap, the dustproof effect cannot be denied. In particular, in the connection terminals of the storage medium, the worst case of data loss may occur due to the presence of foreign matter such as dust, and therefore, a further improvement in dust resistance is desired.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an opening / closing mechanism for an opening which can be easily opened / closed and has excellent dustproofness.

  To achieve the above object, the opening and closing mechanism of the present invention is an opening and closing mechanism for opening and closing an opening of a connection space provided with an internal connection terminal on a main body side to which terminals of an external device or a storage medium are connected.

Holding the opening / closing plate in a state where the opening is closed, and releasing the restriction on the opening / closing plate when the slider advances, and attaching the opening / closing plate to the urging member so that the opening is opened. In power And regulating means for rotating I, further comprising a set to solutions of the problems.

  According to this opening / closing mechanism, when the slider is retreating, the opening / closing plate is restricted from rotating, and the opening / closing plate is held in a state where the opening is closed. The opening / closing of the opening can be operated simply by moving the slider forward and backward because the opening / closing plate is provided with a regulating means for releasing the restriction and rotating the opening / closing plate by an urging member so that the opening is opened. And the operability becomes extremely good.

In the opening / closing mechanism, it is preferable that the opening / closing plate is provided with a decorative cover for substantially opening and closing the opening.
With this configuration, when the slider is moved backward to close the opening, the decorative cover closes the opening, and the decorative cover also functions as a dustproof cover, so that the dustproofness of the connection space is enhanced. Further, for example, by matching the color of the decorative cover with the color of the main body, the design is enhanced.

Further, in the opening / closing mechanism, a forward engagement portion that holds the slider removably at its optimum forward position between the fixed plate and the slider, and a retreat engagement that releasably holds the slider at the optimum retreat position. It is preferred that a part be provided.
With this configuration, when the slider is moved forward and backward, the slider engages with the forward engaging portion or the backward engaging portion at the optimal forward position or the optimal backward position, respectively. The operability is further improved because the user can intuitively confirm that the vehicle has reached the optimum forward position or the optimum backward position.

Further, in the opening / closing mechanism, the restricting means includes a locking piece provided on a slider side of the opening / closing plate, and a locking portion configured to be detachable from the locking piece provided on the fixed plate. And preferably
With this configuration, when the slider is retracted, the rotation of the opening / closing plate is restricted by the engagement of the locking pieces with the locking portions, so that the opening is maintained in a closed state. Further, when the slider moves forward, the engagement is released by the attachment and detachment of the engagement piece from the engagement portion, so that the regulation of the opening / closing plate is released, and the opening is opened.
