Abstract
Abstract A camera comprising a main body section and a rear cover section each having at least one microcmputer therein, and comprising a film rewinding switch disposed in the rear cover section for rewinding a loaded film at an appropriate time. A device is provided, for checking whether the microcomputers in the main body section and the rear cover section can communicate with each other. If the communication between the microcomputers is not possible, the film is rewound independently of the film rewinding switch.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
94 words
A camera having a main body section and a rear cover section and first and second microcomputers disposed respectively in the main body and rear cover sections, wherein the microcomputers transmit data and commands to each other, said camera comprising: a film rewinding switch disposed in the rear cover section, by means of which a loaded film is rewound; means for determining whether said microcomputers can communicate with each other; and means for rewinding the film independently of said film rewinding switch when it is determined that said microcomputers cannot communicate with each other.
Claim 2
Dependent Claim
94 words
A camera having a main body section and a rear cover section and first and second microcomputers disposed respectively in the main body and rear cover sections, wherein the microcomputers transmit data and commands to each other, said camera comprising: a film rewinding switch disposed in the rear cover section, by means of which a loaded film is rewound; means for determining whether said microcomputers can communicate with each other; and means for rewinding the film independently of said film rewinding switch when it is determined that said microcomputers cannot communicate with each other.
Claim 3
Dependent Claim
24 words
A camera as defined in claim 1, wherein said film rewinding switch is monitored by said second microcomputer disposed in the rear cover section.
Claim 4
Dependent Claim
28 words
A camera as defined in claim 2, wherein said film rewinding switch is disposed integrally with other operational switches on an external surface of the rear cover section.
Claim 5
Dependent Claim
26 words
A camera as defined in claim 3, further comprising a date module for recording a date onto the film, said date module including said second microcomputer.
Claim 6
Dependent Claim
39 words
A camera as defined in claim 4, wherein said date module further includes a liquid crystal display for displaying the date to be recorded, said liquid crystal display being disposed on an external surface of the rear cover section.
Claim 7
Dependent Claim
134 words
A camera having first and second microcomputers which transmit data and commands to each other, the first microcomputer being disposed in a main body section of the camera and controlling the camera mechanisms, and the second microcomputer being disposed in a rear cover section of the camera and controlling a display, said camera comprising: a film rewinding switch disposed in the rear cover section and outputting a first signal, said first signal being transmitted to the second microcomputer through the first microcomputer; and film rewinding means for performing film-rewinding in response to a film rewinding signal from the first microcomputer; wherein the first microcomputer sends said film rewinding signal to said film rewinding means upon receipt of said first signal, and also upon detecting that a data communication with the second microcomputer is impossible.
Claim 8
Dependent Claim
134 words
A camera having first and second microcomputers which transmit data and commands to each other, the first microcomputer being disposed in a main body section of the camera and controlling the camera mechanisms, and the second microcomputer being disposed in a rear cover section of the camera and controlling a display, said camera comprising: a film rewinding switch disposed in the rear cover section and outputting a first signal, said first signal being transmitted to the second microcomputer through the first microcomputer; and film rewinding means for performing film-rewinding in response to a film rewinding signal from the first microcomputer; wherein the first microcomputer sends said film rewinding signal to said film rewinding means upon receipt of said first signal, and also upon detecting that a data communication with the second microcomputer is impossible.
Claim 9
Independent Claim
101 words
A method of film-rewinding for a camera having first and second microcomputers disposed respectively in a main body section and a rear cover section of the camera and having a film rewinding switch for rewinding a loaded film, said film rewinding switch being monitored by the second microcomputer disposed in the rear cover section, said method comprising the steps of: determining whether the second microcomputer monitoring said film rewinding switch is able to communicate with the first microcomputer; and rewinding the film independently of said film rewinding switch when the first microcomputer is not able to communicate with the second microcomputer.
Claim 10
Independent Claim
101 words
A method of film-rewinding for a camera having first and second microcomputers disposed respectively in a main body section and a rear cover section of the camera and having a film rewinding switch for rewinding a loaded film, said film rewinding switch being monitored by the second microcomputer disposed in the rear cover section, said method comprising the steps of: determining whether the second microcomputer monitoring said film rewinding switch is able to communicate with the first microcomputer; and rewinding the film independently of said film rewinding switch when the first microcomputer is not able to communicate with the second microcomputer.
