摘要:
A camera includes a display that displays in the viewfinder a photographic screen size even when the low consumption power supply mode is in use. 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. When the power switch is turned on, the CPU causes the panorama frame to move and changes the transmissivity of the viewfinder LCD to match the photographic screen size selected the largest number of times. When a new photographic screen size is selected using the photographic screen size switch, the number of times the photographic screen size has been selected is calculated and stored in the EEPROM. 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.

A camera communicates with an external device using light signals that are transmitted using one or more photoelectric elements. Preferably, the communications are facilitated by using one or more camera photoelectric elements located in a cartridge chamber of the camera, which usually is used to receive a film cartridge. The one or more camera photoelectric elements usually are used to read a bar code on the film cartridge. In order to perform data communications with the external device, a dummy cartridge, which is linked to the external device, is placed in the cartridge chamber and includes one or more cartridge photoelectric elements that oppose the one or more camera photoelectric elements when placed in the cartridge chamber. Communications can take place in one or both directions between the camera and the external device.

In a camera comprising a CPU, a film feeding section, a serial data clock creating circuit section, a PPM conversion circuit section, a photographic information output circuit section, and a magnetic head drive section, the CPU produces a reference clock CLK depending on a film winding speed in the film feeding section, and the serial data clock creating circuit section creates a serial data clock SCK corresponding to the reference clock CLK. The CPU converts photographic information from the photographic information output circuit section into serial data and outputs the serial data in synchronization with the serial data clock SCK. Based on the serial data and the reference clock CLK both from the CPU, the PPM conversion circuit section converts photographic information into a PPM signal and outputs the PPM signal to the magnetic head drive section for magnetically recording it on a film.

An information recording device of a camera permits recording of more photographic information with an appropriate recording density without monitoring the film feeding speed constantly. The information recording device includes a recording assembly that records photographic information on a film recording area of film during film feeding. A feeding speed control assembly reduces the film feeding speed at a first time if the recording of photographic information is complete by the first time after the start of the recording assembly. The feeding speed control assembly reduces the film feeding speed at a second time after the first time if recording of the photographic information is not complete after reaching the first time. The feeding speed control assembly controls the feeding assembly to stop film feeding at a third time after reducing the film feeding speed. A recording control assembly allows information recording by the recording assembly during film feeding time until the film feeding speed is reduced.

A camera comprises a photographic information output circuit section, a CPU, a PPM signal conversion circuit section, a drive section for a plurality of magnetic heads, and a film feeding section. The CPU converts several parallel data items which are output from the photographic information output circuit section into a single serial data item and outputs it to the PPM signal conversion circuit section provided separately from the CPU. The PPM signal conversion circuit section converts this single serial data item into several PPM signals, and then supplies the PPM signals to the magnetic head drive section.

The present invention is applicable to a camera capable of reading in film specific information recorded by means of a bar code. This film specific information is inscribed upon a display portion which rotates together with the forwarding of a film stored within a cartridge. The camera includes: a photointerruptor which optically reads the bar code on the bar code display portion as the bar code display portion rotates together with the forwarding of the film, and which outputs as an electrical signal of the result thus read; a comparator which compares the output signal from the photointerruptor with a threshold level; a calculation device for calculating a standard value for setting the threshold level based upon the output signal from the photointerruptor; a reference value control device which controls the threshold level according to the standard value; and a determination device which determines the film specific information based upon the output of the comparator.

The information is stored in an external storage unit. A recording unit records information on a recording region corresponding to each frame of the film; and a recording control device controls the feeding unit so as to feed the film and controls the recording unit so as to, in synchronization with feeding of the film, record the information about each frame read by the reading device on the corresponding recording region of each frame of the film.

An information recording device of a camera permits recording of more information with an appropriate recording density without monitoring the film feeding speed constantly. The information recording device includes a feeding assembly to feed film mounted in a camera by a motor. A recording assembly records photographic information in the film recording area during film feeding. A feeding speed control assembly starts duty-driving of the motor to reduce the film feeding speed at the first timing and to stop the motor to halt film feeding at a later second timing. The recording control assembly permits recording of the photographic information by the recording assembly until a third timing that is later than the first timing but earlier than the second timing.
