摘要:
An apparatus for monitoring the operation of a measuring unit for obtaining information related to a predetermined parameter. The measuring unit provides an indication of said information having been measured, which can take the form of an indicator lamp, for example. The measuring unit includes a mechanism for inhibiting operation of the indicator for a predetermined time interval, after the elapse of a time period which is related to the information obtained by said measuring unit. The monitoring apparatus measures the length of time of the time period and provides an indication of the time period measured, preferably in terms of the monitored parameter. The disclosed invention is particularly suited to the monitoring of a distance measuring unit or a photometric unit for an automatic camera so that proper operation of such units can be confirmed without having to .�.dissassembly.!. .Iadd.dissassemble .Iaddend.the camera.
摘要:
An electronically controlled camera having a motor for moving a lens associated with the camera. The motor can be switched between a normal rotational direction and a reverse rotational direction. The motor is capable of being driven at a plurality of speeds. The camera is also provided with a controller for controlling the rotational direction and speed of the motor.

A film advancement control device, particularly for an automatic camera. The device detects the presence of film and further includes an external operating switch which enables at least one predetermined function which is unrelated to advancement of the film, in response to the external operating switch being actuated in a predetermined manner. The device also advances the film in a predetermined manner in response to (i) the detection of the presence of the film and (ii) the external operating switch being actuated in the predetermined manner.
摘要:
An apparatus for controlling a strobe which is used in a camera. The strobe control apparatus includes a charging time-limit selecting device for selecting one of plurality of charging times according to the operating conditions of the camera, and a charging voltage limit selecting device for selecting one of plurality of charge limit voltages according to the operating conditions of the camera. If the charged voltage of the strobe does not reach the selected charge limit voltage after the selected charging time has elapsed, charging is stopped. The strobe control apparatus also includes a charge prohibiting device for prohibiting charging if a predetermined charge prohibit time has not elapsed after charging is completed, so as to prevent damage to the strobe due to heat generated by frequent flashings. The predetermined prohibit time is changed, however, according to the sensed heat condition of the strobe.
摘要:
An electronically controlled camera having a macro mode operating capability which is disabled in the event predetermined object-distance-information is not obtained which is required for automatically focusing the camera in the macro mode. In this event, the lens is automatically shifted from the macro position to a non-macro position to enable a properly focused photograph to be taken. The shifting of the lens is preferably performed in response to actuation of the shutter release button while the lens is in the macro position, without further actuation of the shutter release button. Further, the camera can be arranged to return the lens to a macro position after the photograph is taken.

摘要:
An indicator unit for an electronically controlled camera that is able to effectively indicate required information for operating the camera. Such information includes, for example, the frame number of the film in the camera, the focal length of the camera lens, the picture-taking mode, the status of the battery in the camera, and the status of the loading of the film. A display panel constructed according to the invention can display such information within a limited indication space while providing a legible display format. More specifically, the present invention provides an indicator unit for an electronically controlled camera that includes an indicator that is adapted to store a first piece of updatable information in a first memory and another piece of updatable information in a further memory. Display priority is given to the first piece of information stored in the first memory. In response to the further piece of information, the indication status of the indicator is switched from indicating the first piece of information to indicating the other piece of information in accordance with the operation of the indication control device when the switch that is responsive to the other piece of information is operated when the first piece of information being displayed on the indicator.
