Description

本発明は、メモリーカード装置におけるメモリーカードのスロットへの誤挿入を防止する構造を備えたメモリーカード装置に関するものである。   The present invention relates to a memory card device having a structure for preventing erroneous insertion into a slot of a memory card in the memory card device.

従来、図１に示すコンパクトフラッシュ（登録商標）カードと称される半導体メモリーカード（以下、ＣＦカードという。）がある。このＣＦカード１には左右に大小のガイド溝１ａ，１ｂが設けられており、ＣＦカード用のＵ字状のコネクタ２には図２に示すように前記ＣＦカードの両側に設けた大小のガイド溝１ａ，１ｂと嵌合するガイド突起３ａ，３ｂが両側のガイド部３，３に設けられていて、ＣＦカード１のコネクタ２への上下逆挿入防止が図られていた。   Conventionally, there is a semiconductor memory card (hereinafter referred to as a CF card) called a compact flash (registered trademark) card shown in FIG. The CF card 1 is provided with large and small guide grooves 1a and 1b on the left and right, and the U-shaped connector 2 for the CF card has large and small guides provided on both sides of the CF card as shown in FIG. Guide protrusions 3a and 3b that fit into the grooves 1a and 1b are provided on the guide portions 3 and 3 on both sides to prevent the CF card 1 from being inserted upside down into the connector 2.

ところが、多少力を加えながら挿入すると、ＣＦカード１に押されてガイド部３，３が左右に拡がってＣＦカード１をコネクタ端子４のところまで挿入できてしまい、上下逆差挿入によるコネクタ破壊（端子折れ、端子曲がり）、カードのデータ破壊等を防止するのに十分な効果を有することができなかった。
株式会社ワイ・イー・データ、”Internal 7 in 1 Drive”、〔online〕、〔平成１５年８月１日検索〕、インターネット〈URL;http://www.yedata.co.jp/product/jps11043.html〉 However, if inserted with some force applied, the CF card 1 is pushed and the guide portions 3 and 3 expand to the left and right, and the CF card 1 can be inserted up to the connector terminal 4. (Bending, terminal bending), card data destruction, etc. could not be sufficiently effective.

そこで本発明は、上下逆挿入の初期段階で上下逆挿入をユーザに認知させて誤挿入による弊害を防止するメモリーカード装置を提供することを課題とするものである。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a memory card device that allows a user to recognize upside down insertion at the initial stage of upside down insertion to prevent adverse effects caused by erroneous insertion.

本発明は上記の課題を解決するためになされたもので、第１の発明はメモリーカード用のコネクタの前方に設けた本体のフロントパネルの挿入口の左側又は右側に上下逆挿入防止用突起を設けたことを特徴とするメモリーカード装置である。   The present invention has been made to solve the above problems, and the first invention is provided with a protrusion for preventing reverse insertion on the left or right side of the insertion opening of the front panel of the main body provided in front of the connector for the memory card. A memory card device is provided.

第２の発明は、第１の発明において、上下逆挿入防止用突起の巾をＣＦカードの両側に設けられたガイド溝のうち巾が狭いガイド溝より広く、巾が広いガイド溝より狭いことを特徴とするメモリーカード装置である。   According to a second invention, in the first invention, the width of the projection for preventing reverse insertion is wider than the narrow guide groove among the guide grooves provided on both sides of the CF card, and narrower than the wide guide groove. This is a featured memory card device.

本発明は、メモリーカード装置のメモリーカード用コネクタの前方に設けられたフロントパネルの挿入口に、ＣＦカードの側面に設けられた巾の狭いガイド溝（以下、小ガイド溝という。）の巾より広く、巾の広いガイド溝（以下、大ガイド溝という。）の巾より狭い上下逆防止用突起をＣＦカードの上下正しい姿勢における巾の広いガイド溝側に設けたもので、この構成によりＣＦカードを上下逆挿入しようとする場合に、上下逆挿入防止用突起の巾が小ガイド溝より広いので、ＣＦカードの誤挿入を防止することができ、上下正しい姿勢の方向で挿入する場合は上下逆挿入防止用突起の巾が大ガイド溝より狭いので、上下逆挿入防止用突起が大ガイド溝内を通過することができるため、ＣＦカードをＣＦカード用のコネクタに装着することができる。   In the present invention, the width of a narrow guide groove (hereinafter referred to as a small guide groove) provided in the side surface of the CF card is inserted into the front panel insertion opening provided in front of the memory card connector of the memory card device. A wide and wide guide groove (hereinafter referred to as a large guide groove) is provided with protrusions for preventing upside down on the wide guide groove side in the correct vertical position of the CF card. When inserting the card upside down, the protrusion for preventing the upside down insertion is wider than the small guide groove, so it is possible to prevent erroneous insertion of the CF card. Since the insertion prevention protrusion is narrower than the large guide groove, the upside down insertion prevention protrusion can pass through the large guide groove, so that the CF card can be attached to the CF card connector. Can.

従って、上下逆挿入によりコネクタ端子のピン折れや、ピン曲げ、誤位置でのピン接触によるメモリーカードのデータ破壊等を未然に防止することができ、誤挿入の初期段階(挿入口)でユーザにメモリーカードの挿入方向が正常姿勢でないことを認識させることができる。   Therefore, it is possible to prevent the connector terminal from being bent by bending the connector upside down, pin bending, memory card data destruction due to pin contact at the wrong position, etc., and to the user at the initial stage of insertion (insertion). It is possible to recognize that the insertion direction of the memory card is not a normal posture.

図３と図４は本発明の一実施例の斜視図と正面図で、５はメモリーカード装置の本体、６はＣＦカード用のコネクタ２の前方に設けられたフロントパネル、７はフロントパネル６に設けられたＣＦカード１を挿入するコネクタ２用の挿入口、８は挿入口７に設けられた上下逆挿入防止用の突起である。   3 and 4 are a perspective view and a front view of an embodiment of the present invention. Reference numeral 5 denotes a main body of the memory card device, 6 denotes a front panel provided in front of a CF card connector 2, and 7 denotes a front panel 6. An insertion port 8 for the connector 2 into which the CF card 1 provided in the connector 2 is inserted, and a projection 8 for preventing reverse insertion up and down provided in the insertion port 7.

突起８の巾はＣＦカード１の規格の小ガイド溝１ａの巾（０．９９±０．０５ｍｍ）より広く、大ガイド溝１ｂの巾（１．６±０．０５ｍｍ）より狭い大きさである。突起８が大ガイド溝１ｂより狭い巾としたのは、正常姿勢の挿入を保証するためである。   The width of the protrusion 8 is wider than the standard guide groove 1a of the CF card 1 (0.99 ± 0.05 mm) and narrower than the large guide groove 1b (1.6 ± 0.05 mm). . The reason why the protrusion 8 is narrower than the large guide groove 1b is to ensure insertion in a normal posture.

図５は本発明の一実施例の概略説明図で、ＣＦカード１の大ガイド溝１ｂを突起８と向い合う正常姿勢であればＣＦカード１は挿入口７に挿入することができ、ＣＦカード１はコネクタ２に正常に装着される。   FIG. 5 is a schematic explanatory view of an embodiment of the present invention. The CF card 1 can be inserted into the insertion slot 7 in a normal posture where the large guide groove 1b of the CF card 1 faces the protrusion 8. 1 is normally attached to the connector 2.

しかし、ＣＦカード１を上下逆にした姿勢で挿入口７に挿入しようとすると、突起８は小ガイド溝１ａより巾が広いため、ＣＦカード１は挿入口７に挿通することができない。従って、上下逆にＣＦカード１を挿入口７に挿入しようとしても挿入することができないので、ユーザはＣＦカード１を上下逆に挿入しようとしていることを認識することができ、無理なＣＦカードの挿入によるコネクタの破壊や、ＣＦカードのデータの破壊等を事前に防止することができる。   However, if an attempt is made to insert the CF card 1 upside down into the insertion slot 7, the CF card 1 cannot be inserted into the insertion slot 7 because the protrusion 8 is wider than the small guide groove 1 a. Accordingly, since the CF card 1 cannot be inserted even if it is inserted upside down into the insertion slot 7, the user can recognize that the CF card 1 is inserted upside down, and the CF card 1 cannot be inserted. It is possible to prevent the destruction of the connector due to the insertion and the destruction of the data of the CF card in advance.

尚、上記実施例ではメモリーカードとしてＣＦカードを示したが、このカードに限られず、メモリーカードの側面に溝を設けたメモリーカードであれば本発明を適用できることは勿論である。   In the above embodiment, the CF card is shown as the memory card. However, the present invention is not limited to this card, and the present invention can be applied to any memory card in which a groove is provided on the side surface of the memory card.
