摘要:
Electronic camera comprises an image taking unit and a memory unit connected detachably. The image taking unit generates image signals corresponding to an object. The image signals are transmitted to the memory unit to be stored therein. The memory unit is detached from the image taking unit and connected to an external memory device such as a video tape recorder. The image taking unit has a monitor which can display the image signals in visual form before recording them in the memory unit.

An image playback apparatus and in image recording apparatus are designed to permit image playback from a selected position in an image file recorded to a directly accessible memory, such as a magnetic disk. During recording of an image file, the user can designate one or more candidate playback start positions in the file, and corresponding pointers are stored as part of the image file. When the file is to be played back, the playback apparatus accesses the pointer(s) and allows the user to select playback from the corresponding position(s) in the image file. Also the playback apparatus can rewrite pointers in an image file, whereby the user can designate candidate starting positions for future playback of the file.

An improved fire detector unit has a plastic base defining a smoke chamber for detection of a smoke density in terms of light scattering due to the smoke particles in the smoke chamber. The base carries a circuit board mounting a light emitting element, a light receiving element, and other components forming a fire detecting circuit responsible for generating a fire warning signal based upon the detected smoke density. A metal-made electromagnetic shield is molded into the base to protect the light receiving element from electromagnetic radiation noises. The electromagnetic shield includes a ground terminal for connection with a ground line of the circuit board. In addition, terminal pins are molded into the base for electrical and physical connection of the circuit board to the base.
