摘要:
Disclosed is a single lens reflex camera having an electrically driven focal plane shutter. A locking arrangement locks the shutter curtains in their start positions before shutter release to prevent unintentional actuation of an exposure due to faulty operation of switches, shock, or the like. Upon completion of the upward movement of the quick return mirror, the locking mechanism is disabled.

An electromagnetic shutter control device for controlling opening and closing operation of the shutter of a compact folding camera includes a bobbin having a magnetic winding therearound, a stationary permanent magnet over which the bobbin fits for magnetically actuated movement in a longitudinal direction, and guide elements for constraining movement of the bobbin in the longitudinal direction only. The permanent magnet acts to maintain the bobbin in a normal position at the terminal end of its movement coinciding with the closed position of the shutter. Energization of the magnetic winding actuates the bobbin in order to thereby actuate the shutter to the open position. The bobbin and the permanent magnet are particularly formed with a rectangular configuration so that the electromagnetic control device may be shaped to enhance and facilitate the compactness of a camera with which it is utilized.

In an instant, self-developing, and folding camera, a built-in flash unit is disabled as long as the camera is folded. According to another aspect, the flash is disabled after each photograph until the feed motor that drives the film during development has completed its operation. A collapsible bellows forms a dark space between first and second housing sections. When the bellows are folded the flash is drawn to the first section by coupling means. When the bellows are extended the coupling means draws the flash into an operative position.
摘要:
A power supply circuit for a camera wherein a detection circuit which detects the voltage of a power source is provided for supplying an electric power to the electric circuit of the camera only when the detected voltage is above a preset value.In the power supply circuit, the power supply is controlled by a detection output obtained after a voltage detecting action is performed in a stable condition by the detection circuit. The power source voltage is detected in a manner suitable for the characteristic of the battery employed. Further, the voltage detection is performed only momentarily to prevent unnecessary power consumption for voltage detection.

A communication apparatus includes a first communication unit that transmits connection data of a second network to an electronic device by way of a first network, a second communication unit that communicates with the electronic device by way of the second network in accordance with the connection data transmitted by the first communication unit, a storage unit that stores identification data of the electronic device that communicates with the second communication unit, a determination unit that determines whether the electronic device is authorized to communicate by way of the first network based on the identification data of the electronic device stored in the storage unit, and an access control unit that prohibits the electronic device from accessing the communication apparatus by way of the second network when the determination unit determines that the electronic device is not authorized to communicate by way of the first network.
摘要:
An extended function processing apparatus connectable to a plurality of image processing apparatuses. The extended function processing apparatus includes a network interface configured to connect to the plurality of image processing apparatuses, and a receiving unit configured to receive a request for executing an extended function from at least one of the plurality of image processing apparatuses. There are a plurality of execution units configured to respectively execute extended functions in response to the request received by the receiving unit. Further, there is a control unit configured to, when the receiving unit receives the request from one of the plurality of image processing apparatuses, execute the extended function requested using one of the plurality of execution units.
