摘要:
A camera having a photographic optical system contained in a lens barrel including a zoom cam tube and a collapsible mount cam tube. The zoom cam tube is movable in a focal length adjustment region between a Tele position and a Wide position, while the collapsible mount cam tube is movable in a collapsible mount movement region between the Wide position and a fully collapsed position. During focal length adjustment action, a gear which transmits a drive force of a motor is in engagement with a first rack on the zoom cam tube, and only the zoom cam tube rotates. Due to this rotation, a cam portion is rotated via other gears meshed with the first rack, and a pair of viewfinder lenses and a light generating unit, are made movable. During collapsible mount action, the gear is in engagement with a second rack, only the collapsible mount cam tube is rotated, and the drive force of the motor is not transmitted to the cam portion.

A camera having a vibration detection unit to detect the amount of vibration of a camera body and a vibration correction unit to compensate for the amount of vibration detected. The vibration detection unit requires a predetermined amount of time to determine the amount of vibration. If a user desires to take a photograph before the completion of the predetermined amount of time, the photograph will be taken without operation of the vibration correction unit. If the user desires to take a photograph after the completion of the predetermined amount of time, the vibration correction unit corrects for the vibration and, then, the photograph is taken. In addition, while the vibration correction unit is determining the amount of vibration, a display lamp blinks (a first state) and once the vibration detection unit has completed its performance, the display lamp continuously shines (a second state). Further, an indication may be given that the amount of vibration that has been determined is above a maximum value, thereby making the user aware that upper compensation of the vibration is not possible.

A camera has a magnetic head for data recording and reproduction disposed in opposed relationship with a data recording portion provided on film loaded into the camera and adapted to be biased against the film, a pad for pushing the film into contact with the fore end surface of the magnetic head, and a positioning portion formed on the magnetic head. Further, a reference surface is formed in opposed relationship with the positioning portion and bears against the positioning portion to thereby position that surface of the magentic head which contacts with the film at a position in which no deformation is caused in the film. As the reference surface, use may be made of an outer film guild rail which is originally provided in the camera.

A device for flowing a driving current to a motor to drive the motor comprises a capacitor and means responsive to the charging current flowing into the capacitor to supply the driving current to the motor. The responsive includes charging means for supplying the charging current to the capacitor and means for discharging the charge charged in the capacitor during the supply of the driving current to the motor.
摘要:
A heat resistant resin composition comprising a polyamide imide resin having carboxyl groups and modified with an N-methylolated methacryl- or acryl-amide compound and, when desired, further with a bismaleimide compound. The composition has improved properties over conventional polyamide imide resins. When the composition is used, for example, in the form of a film for printed circuit boards, the film has improved heat resistance and enhanced flexural strength and is capable of withstanding soldering baths at high temperatures.
