摘要:
A camera, which uses a film cartridge having a film exposure status display, comprises an E2PROM. The E2PROM stores the fact that the film status determination operation is underway when film status determination operation is underway. When a power supply is removed while the film status determination is operating and then the power supply is mounted, the camera operates an initial process. The film exposure status display is set in `exposed` because the E2PROM holds that the film status determination operation is underway. A camera is .provided that deems the film in the film cartridge to have been exposed and does not perform exposure if the power supply is cut off while the determination of the film status of the film in the film cartridge mounted in the camera is underway.

A camera is detachably mountable with a film cartridge which is provided with a photographic film having a number of successive frames and a film state indicator operable to indicate an exposed state that the film is already exposed, and includes: a film feeding device which feeds the film in a first direction and in a second direction opposite to the first direction; a recording device which records a specified data on the film when the film is being fed in the first direction; a judging device which judges whether the specified data is recorded on the film when the film is being fed in the second direction; and a setting device which is responsive to the judging device and associated with the film state indicator of the film cartridge, and is operable to cause the film state indicator to indicate the exposed state when the specified data is judged not to be recorded on the film.

A camera has a release button, a shutter which operates upon depression the release button, light emitting diode that emits light used to record information on the film, a power source, a switch that closes in response to the operation of the release button to provide power to the light emitting diode, the switch having a first contact point connected to the power source and a second contact point connected to the light emitting diode, and a selecting member movably supported between a first position at which the selecting member prevents the closing of the first and second contact points and a second position at which the selecting member does not prevent the closing of the first and second contact points.

A camera includes: a data generating device which generates a plurality of kinds of data; a data designating device which designates a kind of data to be recorded among the plurality of kinds of data; a record data setting device which sets the kind of data designated by the data designating device as record data when the data designating device designates it, and sets a predetermined kind of data as record data when the data designating device designates no kinds of data; and a recording device which records the set record data on a film mounted on the camera.

A microcomputer provided in a camera body uses a data signal read by sensors facing the data disk of a film cartridge as a positional signal to set the stop position of the spool for providing exposed/unexposed indication to the film. The voltage of the power supply of the camera is detected to modulate a pulse duration by which the number of rotations of the motor can be kept constant in rewinding the film. The sensors are disposed upstream in the rotational direction of the data disk by a certain angle .theta. with respect to the point at which the spool is stopped in order to prevent the dislocation between the display mark of the cartridge and the pointing mark of the data disk. The microcomputer discriminates whether or not data has been read. The mechanism for feeding the film is controlled to set the film at a predetermined position after the decision that the data has been read.

A camera system includes a remote controller and a body of a camera. The remote controller is incorporated in a lens cap of the camera. A photographing magnification for an object is set by the remote controller. A taking lens of the camera is automatically driven to attain an in-focus position defined by a distance to the object and the magnification set by the remote controller. Thus, an image of a desired magnification can be photographed by remote control using the remote controller.

A camera system capable of wireless flash photographing, comprising a camera and an external flash unit, wherein the external flash unit transmits a discriminating data such as a synchronized shutter speed with a wireless flash photographing, and the camera receives the discriminating data. According to the received data, a phototaking operation of the camera is executed.

A trajectory display device includes: a display element; a current position detector; a memory for storing the current position successively; and a position determination unit for determining a plurality of certain actual distance trajectory points and a plurality of direction change points based on position data stored in the memory. The certain actual distance trajectory points are arranged at every actual distance defined by a scale of a map. The moving body changes a moving direction at each direction change point. The display element displays the trajectory including the certain actual distance trajectory points and the direction change points, which is overlapped over the map.

The heat-radiating member 1 shown in FIG. 1 with a tourmaline layer is formed by mixing schorl tourmaline powder having a grain diameter of 3 to 7 μm with a liquid-form fixing agent to form a coating agent, and then applying that coating agent to the surface of a base material, which is made from a metal such as copper, aluminum or the like having excellent heat conductivity, until the density of the schorl tourmaline powder is 0.25 to 0.05 grams per cm2, and allowing it to harden. With this construction, it is possible to provide a heat-radiating member, or devices or parts themselves that can be expected to have a better heat-radiation effect than a heat-radiating member whose base material is treated with a black coating.

A camera system comprises a brightness measuring circuit, a exposure line choosing circuit, an operable switch, a film driver and a film driving mode selector. The brightness measuring circuit measures brightness of a photographic scene to send a brightness value. The exposure line choosing circuit chooses one of a plurality of exposure lines in which each lines selects a combination of an aperture value and a shutter speed value at each brightness value. The film driver drives a film in either of a first mode in which the film is wound only one frame in response to the operation of the operable switch and a second mode in which the film is wound frame by frame continuously as long as the operable member is operated. The film driving mode selector selects one of the modes in accordance with the exposure line chosen by the choosing circuit. In the camera system, a photographer may only select the exposure mode in accordance with his intention and purpose in photography, and then the film driving mode corresponding to the intention and purpose is automatically selected.
