Abstract
A camera with a data recording device separates a connecting line of a magnetic recording device and a connecting line of a film frame detection device to reduce the transfer of electrical noise therebetween. The camera includes a magnetic head for transferring photographic information to and from photographic film and the photographic film includes a magnetic recording track which is capable of magnetic recording of photographic data. A pair of photo-reflectors detects a photographic frame in the photographic film, and a central processing unit is equipped with a frame detection terminal to electrically connect the photo-reflectors with a flexible printed circuit. A terminal for magnetic recording and readout electrically connects to a magnetic head with a pattern on a printed board and a connecting line. The terminal for magnetic recording and readout is physically separated from other high electrical noise terminals to reduce the transmission of electrical noise. Likewise, the flexible printed circuit and the connecting line and respective circuit patterns are physically separated to reduce the transmission of electrical noise.
