Problems solved by technology

In this case, under the configuration disclosed in Patent Document 1, the slide cover formed in front of the insertion opening of the housing will be against the trend of connector miniaturization
Also, the slide cover will limit the circuit design of the substrate (for example, the connection portion where the connector will be connected to the substrate cannot be arranged on the mounting side) and will cause problems that prevent a high-density structure for loading a plurality of memory cards
[0020] Moreover, the structures disclosed in the above-mentioned Patent Documents 2 and 3 that allow only one memory card to be inserted on one side are too complicated in construction for a card connector that allows only two memory cards to be inserted.

Abstract

A card connector includes contacts of two kinds for two memory cards, each adapted to contact a connection portion of the memory card, and a housing having two inserting openings each into which the respective memory card is inserted and arranging and holding the contacts. The two inserting openings are arranged one above the other substantially in parallel relationship, and an insertion-preventing member is arranged in a position between the inserting openings so as not to contact the contacts of two kind so that once either of the memory cards has been inserted, the other memory card is prevented from being inserted by means of the insertion-preventing member. The card connector thus constructed is simple in construction and easy to remove the memory card and can achieve a miniaturization of the connector without limiting design of circuits of substrate.

Description

technical field [0001] The present invention relates to a card connector used in various electric and electronic devices such as printers, a card reader for inputting signals from and outputting signals to various memory cards inserted into the card connector, and more particularly The first refers to a card connector whose construction allows only one memory card to be inserted at a time. Background technique [0002] In recent years, with the widespread use of digital cameras and the like, memory cards having a large storage capacity and a compact shape have been used. Various types of cards are used depending on the nature of the device to which the memory card is applied, such as SD Card (Secure Digital Memory Card) (registered trademark, hereinafter simply referred to as "SD Card"), Memory Stick Card (registered trademark, hereinafter It is only referred to as "MS card" in this document), SmartMedia card (registered trademark, hereinafter only referred to as "SM card")...
