2. Description of the Related Art Conventionally, a memory card has been used for an electronic device such as a personal computer, a video camera, an electronic camera or a mobile phone which uses a memory card having a semiconductor chip built in and a card-shaped outline as an external storage device. A memory card connection device is provided for electrically connecting the provided external connection terminal to a circuit provided in the electronic device. In addition, in this type of memory card connecting device that has been conventionally known, a device that manually inserts and ejects a memory card, and a device that manually inserts a memory card and ejects the memory card return springs and the like. Some of them are automatically performed by using the other, and some of them are automatically performed by using a power source such as a motor to insert (pull in) and eject the memory card.

In a memory card connecting device of a type in which a memory card is automatically inserted and ejected by using a power source, a feed roller is rotationally driven by a motor and acts between the feed roller and the memory card. It is generally used to transfer a memory card in a desired direction by frictional force.

By the way, regardless of the insertion / ejection means of the memory card, the memory card connection device is provided with a card connector having contacts made of elastic metal pieces of the number corresponding to the external connection terminals provided in the memory card. Since the contact is elastically contacted with the external connection terminal provided in the memory card, the external connection terminal is connected to the circuit provided in the electronic device. The force required to insert the memory card into the device is measured by the front side of the memory card (the side on the insertion side to the memory card connection device) coming into contact with the contact,
It becomes the largest until the contactor reaches a predetermined position on the external connection terminal.

Therefore, in the roller-type memory card connecting device with the automatic insertion / ejection function in which the insertion / ejection of the memory card is performed by the feed roller, after the front side of the memory card contacts the contact, the feed roller and the memory card are connected. It is easy to cause a slip between the memory card and the memory card, and it is not easy to insert the memory card smoothly, or a contact failure may occur between the external connection terminal and the contactor provided in the memory card. Such inconvenience becomes particularly noticeable when the feed roller is deteriorated or when the surface of the feed roller is contaminated with dust or oil. In addition, in a roller-type memory card connection device with an automatic insertion / ejection function, it is necessary to generate a large frictional force between the feed roller and the memory card, so the diameter of the feed roller must be increased. Inevitably, there is also a problem that the memory card connection device tends to increase in size.

In order to eliminate the deficiency of the roller type memory card connecting device with the automatic insertion / ejection function, a memory card is placed on a movable tray, and the movable tray on which the memory card is placed is provided with a card connector. Development of a tray-type memory card connection device that is pulled into the housing to electrically connect the contacts provided in the card connector and the external connection terminals provided in the memory card is under consideration.

[0007]

In the conventional memory card connecting device, a header part in which a plurality of contacts are arranged in a predetermined arrangement and a memory card are inserted regardless of the insertion / ejection means of the memory card. A general-purpose type card connector integrally formed with a guide frame for guiding is provided.

Therefore, in developing a tray type memory card connecting device, it is desired to apply the general-purpose type card connector in order to provide the device at a low cost.

The present invention has been made in order to cope with such a demand, and an object of the invention is to connect a memory card with an automatic insertion / ejection function, which can inexpensively insert a memory card smoothly and surely. To provide a device.
