Abstract: A cassette is disclosed for use in combination with a host device, such as a photographic device, having a cassette chamber for receiving the cassette in an operative position, such that when the cassette is operatively positioned in the cassette chamber, an optically coupled interface is established between the cassette and the host device. This interface provides for establishing a two-way communications path between semiconductor memory circuits in a microcontroller within the cassette and a microprocessor, or computer in the photographic device. Thus, the computer in the photographic device can retrieve information stored within the memory of the cassette to automatically make appropriate adjustments within the photographic device. A source of power is carried by the cassette to operate the memory and the optically coupled interface.

Abstract: A cassette has semiconductor memory circuits in a microcontroller and display means which are capable of presenting information from the memory about both the cassette and the web material contained therein. A power source is provided in the housing to operate both the memory and the display when the cassette is not associated with a host photographic device. When the cassette is operatively positioned in the host photographic device, interfacing means are provided for establishing a two-way communications path between the memory in the cassette and the photographic device. Recording means associated with the photographic device are provided for renewing or updating a portion of the data recorded in the memory within the cassette via the interface. In addition, reproducing means associated with the photographic device reproduces a portion of the data previously stored in the memory in the cassette for use by the photographic device.
