Abstract
An electronic camera which detachably connects to a communication interface which allows the camera to communicate with an electronic device such as a personal computer. The communication interface includes circuitry which converts signals utilized by a microprocessor within the camera which are usually within a range of 0 to +5 volts to a level which is utilized to communicate with the computer. When an RS-232 connection is used to communicate between the camera and the computer, the circuitry within the communication interface converts the signals utilized by the camera to a level between -15 and -5 volts for a low signal and +5 and +15 volts for a high signal. The communication interface includes a mechanical connector having two latching mechanisms which connect to receiving members of the camera. The latching mechanisms pivot and are both moved by a single pushing member. The latching mechanisms are constructed as three level elements where the first level includes the latching member, the second level aligns with a level of a frame for supporting the latching mechanism, and the third level includes a surface against which the pushing member pushes.
