摘要:
An exposure controller for use in a photographing apparatus including a flash, includes a diaphragm having a changeable opening to adjust the amount of light reaching a photosensitive medium from a lens optical system, a diaphragm control unit for changing the opening of the diaphragm during the time when a shutter is being opened, and a flash control unit for firing the flash at a predetermined time during the time when the shutter is being opened. This exposure controller enables photography having apodization effect.
摘要:
A system of manufacturing an actuator for driving a to-be-driven object by extension/contraction of a shape memory alloy, the system comprising: a mounting unit configured to mount the shape memory alloy between an actuator body and the to-be-driven object; and a heater configured to heat the shape memory alloy mounted by the mounting unit on a mounting path between the actuator body and the to-be-driven object to a predetermined temperature range.

An image deviation correcting device and an optical apparatus having such a device. The device includes: a driven part to be driven so as to correct an image deviation; a holder for holding the driven part; a first linkage arranged perpendicular to the optical axis of the driven part, the first linkage having four arms connected in a parallelogram, one of the arms being secured to the holder; a middle part secured to opposite arm thereof; a second linkage overlapped with the first linkage in parallel relation thereto, the second linkage having four arms connected in a parallelogram, one of the arms being secured to the middle part; and a base part secured to opposite arm thereof. The one of the arms of the first linkage is generally perpendicular to the one of the arms of the second linkage.
摘要:
A driving mechanism for holding and shifting a part to be driven. The mechanism has at least three carrying elements for carrying the part elastically by exerting force upon the part in directions generally perpendicular to an axis of the part, at least one of the carrying elements being of a actuating type including a frictional actuator, the frictional actuator having a contact face for contacting the part under the pressure, the contact face oscillating at high frequency so as to make the part move in a direction almost rectangular to that of exerting the force upon the part.

In a small camera having multiple functions, a large internal component such as a battery is designed so as to protrude above the top cover flat surface of the camera and the protruding part is covered by an operational cover component such a dial for controlling exposure or other functions of the camera. By having this large internal component located at least partially inside the take-up spool, for example, the height of the camera grip is reduced and the camera as a whole is made smaller.
摘要:
A structure for transmitting a driving force from a camera body side to a cartridge chamber cover side in order to automatically operate a safety mechanism section of a safety locking mechanism installed inside the cover. The safety locking mechanism includes a locking mechanism section for locking the cover relative to the camera body; an unlocking operation member for manually releasing the locking mechanism section; and a safety mechanism section for selectively prohibiting or permitting the operation of the unlocking operation member. The driving force for automatically operating the safety mechanism section is transmitted from the camera body to the safety mechanism section through a winding spool of a film cartridge loaded inside the camera body.
摘要:
A simple and compact opening and shutting apparatus for a film cartridge which has a cylindrical body. The apparatus includes an opening section projecting over the body. The opening section has a film opening and a film cover which opens and shuts the film opening. The apparatus also includes a chamber which holds the cartridge and has a loading opening for loading the cartridge into the chamber. A cartridge cover opens and shuts the loading opening, and there is provided a lock for the film cover. A driver couples the cartridge cover, and a connector connects the lock with the driver so that the film cover is opened when the cartridge cover is shut. The connector is arranged in a concave area which is formed by the surface of the cylindrical body of the cartridge and the opening section projecting over the body.
摘要:
A camera using a film cartridge having a shaft for winding a film and intercepting light, includes: a cartridge chamber for accommodating the film cartridge; a driving unit; a driving source for generating force for driving the driving unit; a transmitting device; and a limiting device. The driving member engages the shaft of the film cartridge accommodated in the cartridge chamber, and rotates the shaft in the film unwinding direction to remove the film from the film cartridge. The transmitting device is provided between the driving source and the driving unit, and transmits the force generated by the driving source to the driving unit. The limiting device is provided in the transmitting device, and limits the force to be transmitted to the driving unit so as to feed the film in the film unwinding direction.
摘要:
An auto focus camera includes a usual zoom lens and provides a pseudo focal length mode, in which the size of focus condition detecting area, to the photographing scene to be printed, is variable. A pseudo focal length is stored and a focus condition is detected in accordance with a ray of light passed through the zoom lens. When the camera is in such a mode as to continuously detect focus condition for keeping an object in focus, or to be operated when the contrast of the object whose focus condition is detected is low, the focal length of the zoom lens and the pseudo focal length are controlled respectively in accordance with the mode.
摘要:
A camera according to the present invention is a camera which feeds a film from a film feed opening of a patrone chamber and it includes a film feeder for feeding the film drawn from the film feed opening to a spool chamber through a film exposure portion, a detector for detecting whether or not the fed film passes through the film exposure portion, and a controller for controlling operation of the film feeder in response to an output of the detector.
