Abstract: An ultrasound observation device includes a depth knob and a pulse generator. The depth knob is operated to switch the display depth of an ultrasound image on a monitor. Upon every rotation of the depth knob by a predetermined angle, the pulse generator generates a switching pulse. A control circuit has a waiting time determiner, which determines a waiting time to start signal processing every time the switching pulse is generated. When a subsequent switching pulse is generated within the waiting time, the waiting time determiner calculates an average generation interval of the switching pulses, and determines a new waiting time based on the average generation interval. When the waiting time elapsed without the generation of a subsequent switching pulse, the control circuit recognizes the end of switching operation, and starts a display switching process under the conditions corresponding to the number of the switching pulses generated.

Abstract: An ultrasonic endoscope has an ultrasonic transducer for emitting and receiving ultrasonic waves, a balloon support, having the ultrasonic transducer, for supporting a balloon mounted thereon to cover the ultrasonic transducer hermetically and removably. In an ultrasonic diagnosis system, the ultrasonic endoscope includes an inflation button adapted to inflating the balloon. A deflation button is adapted to deflating the balloon. Furthermore, a flow line extends to the balloon to pass water. A pump apparatus includes a rotary pump for drawing the water through the flow line, to cause the water to flow into and out of the balloon. A pump controller controls the rotary pump, inflates the balloon by supplying the water in response to an inflation signal from the inflation button, and deflates the balloon by discharging the water in response to a deflation signal from the deflation button.

Abstract: The present invention provides a low-profile printer. The printer has a claw installed on a plane which face an exposure surface of an instant film sheet, a single-rotation cam which completes a sequence of operations, and a three-rotation cam which rotates three times while the single-rotation cam makes a single rotation. The claw is equipped with a holding section which extends to the rear end, in the transport direction, of one of instant film sheets and holds the rear end of the instant film sheet. The raking motion of the claw is caused by the three-rotation cam.

Abstract: Temperature is detected by a temperature sensor disposed near a recording head. When the detection result is a temperature that is higher than room temperature, an appropriate movement amount of the recording head is calculated from a relation between response speed of the temperature sensor and a LED light amount, and a moving speed of the recording head is controlled. When the result of the detection by the temperature sensor is a temperature that is lower than room temperature, an appropriate exposure amount is calculated from the relation between the response speed of the temperature sensor and the LED light amount, and the amount of light emitted by LEDs is controlled.

Abstract: When a film door is opened, and concurrently when an instant film pack is unloaded from a pack compartment, a spring member causes a counter lever to rotate so that an extremity of the counter lever is disengaged from teeth of a gear, and hence is reset. Furthermore, when the film door is closed, a first slope section of a first rib guides a second slope section of a second rib. Moreover, when an instant film pack is loaded, a third rib is pressed by the instant film pack. In any case, the extremity of the counter lever is engaged with teeth of the gear. Thus, a counter is set ready to perform counting operations in response to a subsequent sequence with which instant film sheets are transferred.

Abstract: An image recording apparatus has a pack chamber loaded with an instant film pack storing by stacking a plural pieces of instant film sheets having an image recording section which is exposed and subjected to spreading of a developer to record an image and a developer pool provided on a front end side in a carrying direction from the image recording section, and that carries the instant film sheets stored in the instant film pack loaded in the pack chamber and that performs recording of the image on the instant film sheets, the image recording apparatus comprising: carrying rollers; an exposure section; developing rollers; a carrying roller holding section; and a developing roller holding section.

Abstract: The present invention provides a camera which restrains a photosensitized material from being unstably discharged, while allowing a reduction in diameter of a pair of rollers that feed the photosensitized material out of the camera as well as a transport apparatus which restrains a transported material from being unstably discharged, while allowing a reduction in diameter of a pair of rollers that feed the transported material out of the camera. According to the present invention, an increase in interval between each roller gear fixed to a corresponding one of a pair of rollers and a corresponding one of two roller driving gears meshing with the respective roller gears is suppressed compared to an increase in interval between the roller gears, fixed to the respective rollers.

Abstract: An exposure control method and apparatus for a camera having a two-area divided brightness measurement system. A central light value is determined based on a central area brightness of a photographic scene, and a peripheral light value is determined based on a peripheral area brightness of the scene. After determining by comparison between the central and peripheral light values whether the scene is back-lighted or front-lighted, a correction coefficient specific to back-lighted scenes or that specific to front-lighted scenes is read from a memory. An exposure value suitable for a main subject is calculated according to the following equation: Es=log2{1−(1−&agr;)2LVb−LVa}−log2&agr;+LVa wherein Es represents the exposure value and &agr; represents the correction coefficient.

Abstract: A camera has a movable lens barrel that is stowed in a camera body while the camera is inactive, and is protruded from the camera body to a near range focusing position or a far range focusing position by rotating a drive ring in one direction. The movable barrel returns to the stowed position by rotating the drive ring further in the same direction, because of a cam mechanism interconnecting the drive ring with the movable barrel. To rotate the drive ring, a rotational power of a motor in a first direction is transmitted to the drive ring through a clutch mechanism. The clutch mechanism is switched over according to the rotational direction of the motor and transmits a rotational power of the motor in a second direction to another mechanism. A controller controls driving the motor in response to signals entered through manually operated members, including a power switch, a shutter button and a zone selector, with reference to detection signals from a barrel position detector.
