Description of the invention (Technical field to which the invention belongs) The present invention relates to a card connector device for inserting a small memory card into an electronic machine. [Prior art] Conventionally, for example, a card connector device for inserting a small memory card has been provided in a video camera, a digital camera, or the like. Provide exposed terminals on the small memory card. The card connector device includes a card insertion portion provided in the housing and used for inserting a small memory card, and a connection terminal provided in the card insertion portion and in contact with a card terminal provided on the small memory card. This connection terminal is connected to a printed circuit board by soldering. However, since the printed circuit board is rigid, the card connector device to which the printed circuit board is soldered has a low degree of assembly freedom. That is, there is a problem in that the mounting position of the card connector device is restricted and it is difficult to mount it in a small electronic device. Therefore, in order to solve this problem, the printed circuit board is replaced with a flexible substrate and connected to the connection terminals of the card connector device, thereby increasing the degree of freedom in assembling the card connector device. [Problems to be Solved by the Invention] However, since the flexible substrate is also connected to the connection terminal of the card connector device by soldering in the same manner as the printed circuit board, there are still the same connection operations as the printed circuit board.
