An auto focusing device for foreseeing-calculating lens driving data for making a lens focus on an object after a predetermined time on the basis of the past focus adjusting operation data and the latest focus detection data. A plurality of distance measuring points are read to effect distance measurements at a time. Data suitable for foreseeing calculation is found from the respective distance measuring points, and the data suitable for foreseeing calculation is specified as the latest focus detection data used for the foreseeing calculation.
摘要:
An auto focusing device or a camera including such a device has a focus detecting circuit for detecting the defocus states of a plurality of objects. A calculation circuit calculates a lens position and an aperture value which are capable of placing at least two of the plurality of objects in focus on the basis of the detected defocus states. When a defocus amount difference between the two objects is outside of a predetermined range, the calculation circuit calculates a lens position capable of placing two other objects, the defocused amount difference between which is within the predetermined range, in focus.

A camera including a flash unit comprising an illumination-angle varying mechanism for varying a flash illumination angle. The camera includes a motor, disposed in a camera body, rotatable in a first direction and in a second direction. A clutch switches a direction of drive transmission in accordance with a switching of a direction of rotation of the motor. A first transmission system transmits a rotation of the motor to the illumination-angle varying mechanism in accordance with a switching of the clutch caused by a rotation of the motor in the first direction. A second transmission system transmits a rotation of said motor to a camera-operating mechanism other than a flash unit operating mechanism in accordance with a switching of the clutch caused by a rotation of the motor in the second direction.

A camera system includes a camera body and an interchangeable lens. The camera body includes a camera-side mount, a groove which is disposed in rear of a mount abutting face of the camera-side mount in the direction of the optical axis and which is formed on an outer circumference of the camera-side mount, and a ring-shaped elastic member which is disposed in the groove. The interchangeable lens includes a lens-side mount which is mountable on the camera-side mount, and a tubular protruding part which is disposed in rear of a mount abutting face of the lens-side mount in the direction of the optical axis and which has an inner circumferential face arranged to come into pressure contact with the ring-shaped elastic member.
摘要:
In an electric motor drive device for a camera having first and second one-way clutches arranged to transmit a driving force either to a film winding transmission member or to a film rewinding transmission member by a change-over operation on the rotation of a driving motor between normal and reverse rotating directions, a charge cam provided between the first one-way clutch which transmits a driving force of the rotation of the motor in the normal direction to the film winding transmission member and the winding transmission member is arranged to rotate together therewith. The charge of a charge mechanism disposed within the motor drive device resulting from the rotation of the charge cam is arranged to be effected approximately in phase with the charge of a charge mechanism which is disposed within the camera and is arranged to be driven by the winding transmission member.

In the disclosed camera system, a spring arrangement to drive an automatic exposure mechanism of a camera and a magnet arrangement to control starting and stopping of the AE mechanism of the camera are provided within an electric drive device, and the automatic exposure control of the camera is carried out by mounting the electric drive device on the camera. Facilities, when energized by a power supply, are set to supply driving power to a motor for cocking the shutter, and an arrangement supplies power from the power source to the magnet arrangement for actuating the magnet arrangement. The present invention eliminates disadvantages of prior camera systems, namely, inferior response characteristic of the magnet and erroneous operations by the release action, and a large number of connecting terminals.
