摘要： A magnetic recording and regenerating unit for photographic film and a camera, which feed photographic film coated with a magnetic recording layer, records magnetic information in the magnetic recording layer, and regenerates magnetic information from the magnetic recording layer. In the magnetic recording and regenerating unit for a camera, the number of turns of a coil wound around a core included in a magnetic head is small. Thus, one magnetic head is able to record and regenerate magnetic information. The number of turns of the coil is determined so as to output a regenerated waveform which does not enable reading of the magnetic information but permits determination of whether any magnetic information is recorded or not. Whether any magnetic information is recorded or not is determined based on the output voltage from a smoothing circuit, a peak hold circuit, etc. which receive signals output from the magnetic head via an amplifier.

摘要： A camera which includes a recording unit for recording photographic information in a record area on a magnetic layer of a photographic film for each exposed frame, and a regenerating unit for scanning the magnetic layer to determine the presence or absence of the recorded information. The regenerating unit includes a magnetic head for scanning the magnetic layer and generating a corresponding signal, an amplification circuit for amplifying the signal generated by the magnetic head, a smoothing circuit for obtaining an envelope waveformn, and a magnetic information detecting circuit for determining whether magnetic information is recorded in the magnetic record area for each frame on the photographic film by sampling the voltage level of the signals output from the smoothing circuit a plurality of times, integrating or averaging the sampled voltage levels, and comparing the integrated or averaged sampled voltage levels with a reference voltage. The magnetic head has a small number of coils sufficient for detecting the presence of recorded information, but insufficient for accurately reproducing the recorded information.

摘要： A range finder circuit for a passive-type autofocusing device includes three line photosensors. Secondary differences of their output signals and the zero-cross points of the secondary differences are detected and stored. A coincidence detecting circuit compares the stored zero-cross behavior signals and detects a coincidence of these zero-cross behavior signals. A range finding is obtained from the coincidence information. According to one embodiment of the invention a first photosensor is selected as a reference photosensor and zero-cross behavior signals obtained from the other photosensors are successfully shifted relative to the zero-cross behavior of the reference photosensor until a coincidence is detected. According to another embodiment of the invention, a pixel location of one photosensor where zero-cross data exists is provided with a predetermined width tolerance on both sides of the pixel location. A coincidence is detected when zero-cross data from the other two photosensors fall within the width tolerance of the pixel location. According to yet another embodiment of the invention, a deviation from coincidence memory circuit is coupled to the coincidence detecting circuit. The deviation from coincidence memory stores a deviation from coincidence when zero-cross data from the other two photosensors are coincident with each other. The deviation from coincidence is represented by an absolute value of the difference between the location of the coinciding zero-cross data of the other two photosensors after being shifted and the location of the reference zero-cross data which coincides with the coinciding zero-cross data of the other two-photosensors.
