Abstract
Abstract A camera has a recording apparatus for magnetically recording finished photograph information, indicating exposure of a film frame, and for magnetically recording other photograph information for each film frame. The finished photograph information is recorded at a designated film area, while a film feed motor is in a transient speed state. Other photograph information is recorded in a designated film area when the film feed motor speed is constant. Appropriate positioning of the designated recording areas for recording information therein is determined by counting film perforations or by measuring a period of time during film feed subsequent to an exposure.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
84 words
Information recording apparatus, comprising: film feed means having a motor for feeding a film; recording means for recording first information and second information different from said first information on said film; and control means for causing said recording means to record said first information on the film while the motor is starting or stopping and for recording said second information on the film only when the motor speed is substantially constant, said first information and said second information being recorded at different recording frequencies.
Claim 2
Dependent Claim
84 words
Information recording apparatus, comprising: film feed means having a motor for feeding a film; recording means for recording first information and second information different from said first information on said film; and control means for causing said recording means to record said first information on the film while the motor is starting or stopping and for recording said second information on the film only when the motor speed is substantially constant, said first information and said second information being recorded at different recording frequencies.
Claim 3
Dependent Claim
33 words
The apparatus as defined in claim 1, wherein said control means causes said recording means to record said second information at a recording frequency higher than a recording frequency of said first information.
Claim 4
Dependent Claim
17 words
The apparatus as defined in claim 1, wherein said information recording apparatus is provided in a camera.
Claim 5
Dependent Claim
95 words
Information recording apparatus which is capable of recording information onto a film, comprising: film feed means having a motor for feeding a film having a plurality of perforations spaced in a feed direction of the film; recording means for recording information onto said film; detecting means for detecting an area disposed on the film, onto which said information is recorded, in accordance with said perforations during feeding of the film; and control means for causing said recording means to record said information onto the film in accordance with a detection result of said detecting means.
Claim 6
Dependent Claim
95 words
Information recording apparatus which is capable of recording information onto a film, comprising: film feed means having a motor for feeding a film having a plurality of perforations spaced in a feed direction of the film; recording means for recording information onto said film; detecting means for detecting an area disposed on the film, onto which said information is recorded, in accordance with said perforations during feeding of the film; and control means for causing said recording means to record said information onto the film in accordance with a detection result of said detecting means.
Claim 7
Dependent Claim
90 words
The apparatus as defined in claim 4, wherein said motor has transient speed states which are a starting state and a stopping state of the feeding of each film frame and has a constant speed state after a predetermined length of film has been fed, and wherein said control means causes said recording means to record said information onto the film during said constant speed state and causes said recording means to record during said transient speed state finished photograph information indicating that a corresponding film frame has been exposed.
Claim 8
Dependent Claim
17 words
The apparatus as defined in claim 4, wherein said information recording apparatus is provided in a camera.
Claim 9
Dependent Claim
56 words
The apparatus as defined in claim 4, wherein said detecting means detects a time when said motor is decelerated in accordance with said perforations during feeding of the film, and wherein said apparatus further comprises record controlling means for ceasing recording of said information by said recording means in response to the detection of said time.
Claim 10
Dependent Claim
56 words
The apparatus as defined in claim 7, wherein said detecting means detects a time when said motor is stopped in accordance with said perforations during feeding of the film, and wherein said apparatus further comprises record controlling means for ceasing recording of said information by said recording means in response to the detection of said time.
Claim 11
Dependent Claim
84 words
Information recording apparatus, comprising: a film feeding unit having a motor to feed a film; a recorder to record first information and second information different from said first information on said film; and a controller to cause said recorder to record said first information on the film while the motor is starting or stopping and to record said second information on the film only when the motor speed is substantially constant, said first information and said second information being recorded at different recording frequencies.
Claim 12
Dependent Claim
84 words
Information recording apparatus, comprising: a film feeding unit having a motor to feed a film; a recorder to record first information and second information different from said first information on said film; and a controller to cause said recorder to record said first information on the film while the motor is starting or stopping and to record said second information on the film only when the motor speed is substantially constant, said first information and said second information being recorded at different recording frequencies.
Claim 13
Dependent Claim
33 words
The apparatus as defined in claim 9, wherein said control means causes said recording means to record said second information at a recording frequency higher than a recording frequency of said first information.
Claim 14
Dependent Claim
17 words
The apparatus as defined in claim 9, wherein said information recording apparatus is provided in a camera.
Claim 15
Dependent Claim
93 words
Information recording apparatus which is capable of recording information onto a film, comprising: a film feeding unit having a motor to feed a film having a plurality of perforations spaced in a feed direction of the film; a recorder to record information onto said film; a detector to detect an area disposed on the film, onto which said information is recorded, in accordance with said perforations during feeding of the film; and a controller to cause said recorder to record said information onto the film in accordance with a result of said detector.
Claim 16
Dependent Claim
93 words
Information recording apparatus which is capable of recording information onto a film, comprising: a film feeding unit having a motor to feed a film having a plurality of perforations spaced in a feed direction of the film; a recorder to record information onto said film; a detector to detect an area disposed on the film, onto which said information is recorded, in accordance with said perforations during feeding of the film; and a controller to cause said recorder to record said information onto the film in accordance with a result of said detector.
Claim 17
Dependent Claim
