A filtration device efficiently sizes removal of unnecessary substances adhering to and deposited on a filter medium of a filter element during filtration and backwashing (cleaning) from target (non-filtered) substances. The filter element captures substances in a fluid on one surface of a filter medium. The captured substances are separated from the filter medium during backwashing. A brush moves relative to the one surface of the filter medium and assists in separating the captured substances and sifting during the relative movement. The backwashing starts when a differential pressure between both surfaces of the filter medium exceeds a predetermined value, or the like while performing the filtration, and returns to filtration after the differential pressure is eliminated or after a predetermined time elapses. The brush sifts the unnecessary substances from the captured substances and passes the removal to the other surface side during the filtration.

A battery check device for a portable electronic apparatus, such as a digital camera, for example, can selectively use a plurality of types of batteries. The battery check device comprises a battery determining processor that determines a type of battery, when the battery is mounted in the portable electronic apparatus. A battery check processor is provided for checking the residual battery power in accordance with the determined battery type for the mounted battery. An indicating processor indicates the plurality of types of batteries that can be mounted in the portable electronic apparatus. The indicating processor further indicates the determined battery type.

Battery check device

A camera system includes a camera body including a photometering device and an external operating device, and a photographing lens which is detachably attached to the camera body, the photographing lens including an aperture setting device for selecting an auto aperture setting and at least one fixed aperture setting. A full-aperture photometering operation is performed when the aperture setting device is positioned at the auto aperture setting, and a stop-down photometering operation is performed in response to an operation of the external operating device when the aperture setting device is positioned at the fixed aperture setting.

A microcomputer has a ROM with pre-stored programs, a RAM storing a revision program for executing an interruption-processing, and a program counter in which an address is successively renewed during an execution of the ROM-stored programs. A first register stores a comparison address corresponding to an optional address of the ROM-stored programs, at which an interruption-processing should be executed to virtually revise the ROM-stored programs. A second register stores a vector address data corresponding to a head address of the revision program. An address comparator compares the comparison address data with a renewed address of the program counter. A controller/calculator makes an access to the head address of the revision program, corresponding to the vector address data of the second register, when there is a coincidence between the comparison address data and the renewed address of the program counter, resulting in an execution of the interruption-processing in accordance with the revision program.

Microcomputer with program-revision ability

A camera system having a camera body and a photographing lens, which can be mounted to and dismounted from the camera body, includes a determining device which determines a type of the photographing lens in accordance with data received from the photographing lens; and a body controller which has a function to send body data and individual function data to the photographing lens, wherein each of the individual function data is required for a corresponding function that the photographing lens possesses. The body controller sends all the body data to the photographing lens regardless of the type of the photographing lens, and sends a portion of the individual function data which is associated with the type of the photographing lens to the photographing lens.

Camera system having a communication system between a camera body and a photographing lens

A camera system includes a photographing lens having a lens memory and/or a lens controller, and a camera body including a body controller which can communicate with the lens memory and/or the lens controller; a first power and a second power which can be supplied to the photographing lens. The lens memory and the lens controller operate with the first power and the second power, respectively, when the photographing lens is mounted to the camera body. The body controller supplies the first power to the photographing lens to drive the lens memory to read data from the lens memory, and subsequently disables the lens memory and supplies the second power to the lens controller so that the body controller and the lens controller communicate with each other if the body controller determines, from the lens data, that the photographing lens includes the lens controller.
