Abstract: In a chip-type electronic component of the present invention, at least one surface of a ceramic body is a convexly curved surface. Specifically, at least one surface in a thickness direction of the ceramic body may be convexly curved, and the side surface of the ceramic body may be concavely curved. Alternatively, only one surface may be a convexly curved surface. This chip-type electronic component has a high visibility and a high mechanical strength, though it is small. Moreover, in a chip-type electronic component comprising a ceramic body that is formed by alternately laminating insulating layers and conductor layers, and a pair of external electrodes, the thickness in a laminate direction at the central part between external electrodes of the ceramic body is made greater than the thickness of the end surface. This prevents breakage of the external electrodes and also enlarges the ceramic body.

Abstract: A film rewinding apparatus for a camera is described whereby the completion of film rewinding is accurately timed even if environmental conditions change. First edge detecting mechanism is positioned on a winding-spool side of the camera on a path on which perforations of the film pass and second edge detecting mechanism is positioned on the film cartridge side of the camera. A set time period used by a timer for timing the completion of the film rewinding is calculated based on a time period during which perforation edges detected by the first edge detecting mechanism are detected by the second edge detecting mechanism. If the perforation edges of the film are not detected within the set time period, a determination is made that the film rewinding has been completed and the rewinding operation is terminated.

Abstract: A film feed control apparatus feeds film with an electrical feeding mechanism in a film feeding direction and stops the film at predetermined positions. The film includes a plurality of photo frames. A predetermined number of perforations having edges at leading and trailing sides of the film are defined at predetermined positions at the photo frames. An edge detector detects edges of the perforations of the film as the film is fed in the feeding direction. A physical amount detector detects a physical amount that relates to an amount of film that is fed from a time when the film feeding starts to a time when an edge of a predetermined perforation is detected. The physical amount detector also detects a physical amount that relates to an amount of film that is fed from the time when the edge of the predetermined perforation is detected to a time when another edge is detected.

The camera includes a power source, a controller, a film winding motor, a panorama frame driving motor, a CPU, an EEPROM, a viewfinder LCD and a timer.

In addition, the time that has elapsed after the power switch has been turned on is measured by the timer, and when the time exceeds a predetermined value, the camera moves into the low consumption power supply mode with power still being supplied to the viewfinder LCD.
