Abstract
Abstract A photographic camera records photographic information and/or development information in an IC card which includes a semiconductor memory capable of reading-out/writing in, a circuit having a microcomputer and adapted for communication with peripherals and a data communication terminal for the communication. This photographic camera has an attaching portion for attaching the IC card, a data exchange terminal disposed between a back lid and a camera body, a microcomputer-incorporated communication device for the data exchange with the IC card and a camera control device for carrying out various operations based on the data input from the IC card. Through the data exchange between the microcomputer of the camera and the microcomputer of the IC card, the photographic information and/or the development information corresponding to an exposed film is recorded in the IC card. Those data and other information are accessible at any time and any place.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
83 words
A photographic camera, comprising: an attaching portion disposed at a back lid of said camera and adapted for detachably attaching an IC card including semiconductor memory means capable of reading-out/writing-in, a circuit for communication with peripherals and a data exchange terminal for communication; communication means disposed in a body of said camera for communicating data with said IC card; and camera control means disposed in the body of said camera for carrying out camera operations based on data input from said IC card.
Claim 2
Dependent Claim
83 words
A photographic camera, comprising: an attaching portion disposed at a back lid of said camera and adapted for detachably attaching an IC card including semiconductor memory means capable of reading-out/writing-in, a circuit for communication with peripherals and a data exchange terminal for communication; communication means disposed in a body of said camera for communicating data with said IC card; and camera control means disposed in the body of said camera for carrying out camera operations based on data input from said IC card.
Claim 3
Dependent Claim
50 words
A photographic camera, as defined in claim 1, wherein said camera control means, includes; means for judging through a data exchange whether or not said IC card is attached, and means for selectively changing the camera operations depending on whether or not said IC card is judged to be attached.
Claim 4
Dependent Claim
32 words
A photographic camera, as defined in claim 1, wherein said camera control means based on data from said attached IC card carries out a display to indicate attachment of said IC card.
Claim 5
Dependent Claim
79 words
A photographic camera, as defined in claim 1, further comprising; means disposed in the body of said camera for outputting information obtained at a time of photographing, the information outputting means being operatively connected to the communication means; wherein said communication means communicates said information from said outputting means in said camera body to said attaching portion of the back lid each time the photography takes place by one frame, and said information is stored in said IC card.
Claim 6
Dependent Claim
21 words
A photographic camera, as defined in claim 4, wherein said stored information is used in developing and printing an exposed film.
Claim 7
Dependent Claim
81 words
In a photographic camera having a back lid and a body including a first microcomputer, an IC card, comprising: a housing detachably mounted at the back lid; a second microcomputer disposed within the housing; a semiconductor memory disposed within the housing and operatively connected to the microcomputer; and a plurality of terminals disposed on the housing and operatively connected to the second microcomputer and the memory, wherein the terminals bidirectionally conduct a plurality of signals between the first and second microcomputers.
Claim 8
Dependent Claim
81 words
In a photographic camera having a back lid and a body including a first microcomputer, an IC card, comprising: a housing detachably mounted at the back lid; a second microcomputer disposed within the housing; a semiconductor memory disposed within the housing and operatively connected to the microcomputer; and a plurality of terminals disposed on the housing and operatively connected to the second microcomputer and the memory, wherein the terminals bidirectionally conduct a plurality of signals between the first and second microcomputers.
