Solid state camera having a camera body for supporting a recording medium

A solid-state camera having a camera body for supporting a recording medium and employing as the recording medium a solid-state memory cartridge for recording signals, said solid-state memory cartridge being capable of being loaded into and unloaded from the camera body, first signal-transmission means provided on the camera body and the solid-state memory cartridge for permitting the transmission of a signal between the camera body and the solid-state memory cartridge loaded therein while assuming a first loading state, and second signal-transmission means provided on the solid-state memory cartridge for permitting the transmission of a signal between the camera body and the solid-state memory cartridge by connecting said second signal-transmission means of the solid-state memory cartridge and said first signal-transmission means of the camera body when the solid-state memory cartridge and the camera body are connected in a second loading state different from the first loading state.

A solid-state camera having a camera body for supporting a recording medium and employing as the recording medium a memory cartridge for recording signals, said solid-state memory cartridge being capable of being loaded into and unloaded from the camera body, a signal connector provided on the camera body, and a signal connector provided on the central portion of one side surface of the memory cartridge for transmitting a signal between the camera body and the memory cartridge,

• wherein a first signal connector formed by one of said signal connectors on the camera body and the memory cartridge has a plurality of contacts divided into groups disposed at positions which are, on a surface of contact with the other or second signal connector, rotationally symmetrical about the normal through said surface of contact, the second signal connector having a plurality of contacts each capable of being connected to one of those contacts of the first signal connector which are within the group disposed at one point symmetrical position.

An information recording system having an information writing and reading apparatus and employing as an information recording medium an unloadable solid-state memory device inserted into an inserting portion of the apparatus, said writing and reading apparatus being adapted for writing signals on and reading signals from said solid-state memory device, said solid-state memory device being adapted to store signals, a signal connector provided on the information writing and reading apparatus;

• and a signal connector provided on the central portion of one side surface of the solid-state memory device for transmitting a signal between the information writing and reading apparatus and the solid-state memory device,
• wherein a first signal connector formed by one of said signal connectors on the information writing and reading apparatus and the solid-state memory device has a plurality of contacts divided into groups disposed at positions which are, on a surface of contact with the other or second signal connector, rotationally symmetrical about the normal through said surface of contact, the second signal connector having a plurality of contacts each capable of being connected to one of those contacts of the first connector which are within the group disposed at one point symmetrical position.
