摘要： A data printing apparatus of this invention controls the emission timing or the emission interval of a light-emitting means on the basis of a signal according to traveling of a sheet film along a traveling path so as to print data free from blurring of characters or a variation in interval between characters on the sheet film having no perforations. After an exposure operation is ended, the apparatus feeds the sheet film from an exposure position along a spool wall. Light corresponding to digital numerals representing a date is emitted by light-emitting elements, and the date to be printed by the light-emitting elements is focused on the sheet film by an optical system. The date on the sheet film is printed during traveling of the sheet film along the spool wall. The apparatus also includes a photoreflector, arranged in a traveling chamber of the film, for detecting an emulsion portion on which an object image from a photographing lens is exposed, and the remaining frame portion on the basis of a difference in reflectance, and a timer for measuring a moving time from when the frame portion is detected by the photoreflector until the emulsion portion is detected thereby, and controls the emission timings of the light-emitting elements on the basis of the moving time.

摘要： An automatic focusing camera, after determining composition of an object being photographed within a range finding frame disposed at the center of a finder, repeats operations of detecting a range difference between an image forming position and a predetermined focusing position of the object and of storing the detected range difference, before a shutter release button is half-depressed, and, after being half-depressed, drives a taking lens in accordance with a range difference based on the latest information stored immediately before the half-depression to stop the taking lens at the predetermined focusing position, thereby enabling the lens setting without a time lag even when the object being photographed is in a low brightness.

摘要： Apparatus for delivering distance information of a camera includes counter means which counts a relative distance corresponding to a movement of a taking lens. The counter means is reset when the taking lens reaches a reference position located at infinity. Using stored data (absolute distance factors) which is specific to a taking lens and the count in the counter means, an absolute distance is derived.

摘要： An automatic focusing camera includes a sensor for detecting an amount and a direction of difference between an image forming position of light from an object being photographed and a film surface to drive a taking lens in response to the measured outputs and focus determining capability which gives a decision of in-focus when the amount of difference is less than a first automatic focusing threshold. A focusing operation is achieved such that, comparing the amount of difference determined by the sensor with a second automatic focusing threshold of a standard value which is larger than the first automatic focusing threshold, when the amount is less than the second threshold and a direction of difference last measured and that presently measured are the same, a taking lens driving is continued to complete a focusing operation and when the directions are different from each other, the measurement is resumed after the next driving of the taking lens even when the amount is less than the second threshold.

摘要： A one-chip microcomputer system includes a one-chip microcomputer, a nonvolatile memory which can electrically rewritably store changing data of a program stored in a mask ROM of the one-chip microcomputer, an input unit (connection unit) for receiving data to be written in the nonvolatile memory from an external device, and an object to be controlled by the one-chip microcomputer. In one aspect, the nonvolatile memory has first and second correction data areas, and first and second memories for respectively designating these areas. Upon reception of an initialization signal from the external device connected to the input unit, only the second memory for designating the second correction data area is initialized. In another aspect, the mask ROM stores ROM version data, and the nonvolatile memory stores board version data. Upon writing of the data via the input unit, bug correction data is selected based on the ROM version data and the board version data, and the selected data is written in the nonvolatile memory. In still another aspect, the nonvolatile memory has a first area for storing data for correcting a bug in the program, a second area for storing data for changing a specification of the object to be controlled, and a third area for determining whether or not data are stored in the first and second areas.

摘要： A camera of this invention detects the presence or absence of magnetic data and prevents at least occurrence of a frame of double exposure or unexposed frame even under the influence of an electromagnetic noise. The position of a perforation of a film is detected by a position detecting section and whether a magnetic head is set in contact with a recording area adjacent to an exposed frame or a recording inhibition area adjacent to a portion between the adjacent exposed frames is determined. A threshold value used for determining the presence or absence of magnetic data is set in a threshold setting circuit based on an output generated when the position detecting circuit determines that the magnetic head is set in contact with the recording inhibition area. An output of the magnetic head is compared with the threshold value by a determination circuit and the presence or absence of magnetic data in the recording area is determined when the position detecting circuit determines that the magnetic head is set in contact with the recording area. Whether the operation of the magnetic head is permitted or inhibited is determined based on an output of the determination circuit.
