摘要： PROBLEM TO BE SOLVED: To surely discriminate the use state of a film cartridge by turning a spool driver on a camera side to a fixed standby position, at the time of loading the film cartridge. SOLUTION: A bottom cover 53 is opened to load the film cartridge 10 in a cartridge loading chamber 51. The spool driver 55 is in a turned state to an exposure completion position Ed, regardless of the use state of the film cartridge 10 taken out in the previous time. Therefore, when the spool 13 of the film cartridge 10 loaded in this time is at an exposure completion position Es, a driver shaft 62a is inserted into the engaging hole 28 of the spool 13 and an engaging projection 63a is engaged with a key groove 28a. But when the spool 13 and the exposure completion positions Es do not coincide, the engaging projection 63a is pushed upward against the energization of a coil spring 64 on the peripheral part of the engaging hole 28, not to be engaged. Thus, even if the film cartridge is loaded in any use state, the use state can be accurately discriminated.

摘要： PROBLEM TO BE SOLVED: To enable sure reading processing for a data disk, even if a cartridge film provided with the data disk is loaded, after the opening/closing operations of a cartridge cover for a camera are executed without loading the cartridge film. SOLUTION: The camera is equipped with a detecting switch 40 for detecting the presence of the loading of the cartridge film CFL and a spool key 34 connected to the spool of an unexposed cartridge film CFL at a fixed angle position, when this unexposed cartridge film CFL is loaded, in a cartridge loading chamber 32. This chamber 32 is covered/uncovered with the cartridge cover 30. When the cartridge cover 30 is opened/closed in a state where the cartridge film is not loaded in the chamber 32, a microprocessor in a camera body 2 decides the unloaded state, based on the output of the detecting switch 40 and the spool key is kept stopping at a different fixed angle position from the above-mentioned fixed angle position.

摘要： PROBLEM TO BE SOLVED: To provide an excellent photograph by improving the flatness of film fed to an exposing position behind an aperture after the film is fed by one frame. SOLUTION: After finishing photographing for one frame, a take-up driving shaft is driven in a film take-up direction and the photographic film 11 is fed in a direction shown by an arrow. By feeding the film as shown by the figure (a) after a sensor 35 detects perforation 42, the driving of the take-up driving shaft is stopped. Next, a spool driving shaft is driven in a film rewinding direction and decelerated, and the film 11 is fed in a direction shown by a dotted line arrow. When the sensor 35 detects the perforation 42 as shown by the figure (b), a feeding motor is stopped. Since the film 11 is tensioned, the flatness of the film fed to an exposing range behind the aperture is correctly kept.

摘要： PURPOSE: To make it possible to execute data recording at a stable recording density by preventing the fine fluctuation in recording density. CONSTITUTION: The rotating period of a motor 11 is detected by an encoder 40 and ENC pulses are generated from an encoding pulse generator 41. A slight fluctuation removing section 43 converts the respective pulse periods of ENC pulses to voltage and passes the voltage through a low-pass filter. After the voltage is converted to the pulses of the pulse periods corresponding to the voltage of the resulted signal, the pulses are sent to a total pulse counter 45 and a pulse interval measuring counter 46. This pulse interval measuring counter 46 measures the pulse period tn from the slight fluctuation removing section 43 and sends the pulse period to a multiplier 48. This multiplier 48 inputs value TW obtd. multiplied by a coefft. K and the pulse period tn to a timer 49. This timer 49 frequency-divides a basic clock by the value TW and sends the pulses of the period TW via an AND circuit 50 to a shift register 51. This shift register 51 sends data by each one bit to a head driver 52 at every timing of these pulses. A magnetic head 30 changes over the writing data at this timing and successively magnetically records the data to a magnetic recording layer 20.

摘要： PURPOSE: To stop a spool at a position where a prescribed using state notation is displayed based on a passing time in a prescribed section on a bar-code rotary disk which is integrally rotated with a spool for a film cartridge and a previously obtained angle ratio in the prescribed section. CONSTITUTION: A data disk 14 is rotated in a direction shown by an arrow X at a constant speed, A 1st period Tq as a passing time in a quiet zone 14a is measured by an optical sensor 40, next, the Ap /Aq of the rotating angle Aq of the quiet zone 14a to a rotating angle Ap from the starting end position of the quiet zone 14a up to the optical sensor position when 'exposed' is displayed is calculated, thereafter, a 2nd period Tp is calculated by the expression (Ap /Aq ×Tq ), and the spool 12 is stopped after the lapse of the 2nd period Tp after detecting the starting end position of the quiet zone 14a.

摘要： PURPOSE: To perform excellent signal processing for read information signals by switching the constitution of the photoelectric conversion circuit of a bar code sensor in accordance with the kind of an input information signal in the case that adjusting information for a camera is inputted by the bar code sensor reading the bar code information of a bar code plate. CONSTITUTION: When it is confirmed that a teat mode SW113 is turned on in a microcomputer 104, a setting operation for a receiving state for the information signal from an information inputting device is started, so that the voltage level of a terminal I2 is set to be in a state H. When the terminal I2 is in the state H, an NPN transistor 110 is turned on, and the voltage level inputted to the terminal I1 of the microcomputer 104 is at a value obtained by multiplying photoelectric current value i0 received by a photodetector 102 by the combined resistance value Rv R1 /(Rv +R1 ) or variable resistance 108 and fixed resistance 109.
