摘要:
There is provided a photographic stop unit (80) comprising a fixed stop plate (31), a movable stop plate (32), and shield plates (33, 33′). A plurality of apertures (32a, 32d, 32d′) is formed in the movable stop plate (32). In monocular photography, the movable stop plate moves downward, a center stop (31a) of the fixed stop plate opens, and monocular photography of the ocular fundus is performed. In stereo-photography, the movable stop plate moves upward, the center stop (31a) is closed, the shield plates (33, 33′) move to the open position or the closed position in this state, the apertures (32d, 32d′) for stereo-photography are alternately opened, and stereo-photography of the ocular fundus is carried out. In such a configuration, monocular photography and stereo-photography can be carried out at high speed in a simple configuration because the apertures of the photographic stop can be switched at high speed.

In an apparatus that measures an optical property of an eye to be examined (A) to irradiate laser beam and to receive scattered light of a laser beam by a measurement unit (3). In the apparatus, the position of the measurement unit (3) with respect to the eye (A) is adjusted relatively based on images of the eye (A), photographed from front and oblique direction, and displayed on a monitor fixed the back of the measurement unit (3). According to the apparatus, the optical properties of the anterior ocular segment can be measured with high reproducibility, and alignment is east to perform.

An imaging system is provided that is capable of controlling a photographic operation to provide favorable images of a fundus of an eye to be examined. When a normal photographic mode is selected, a single operation of a shutter button causes a single trigger signal to be generated. On the other hand, when a stereo photographic mode is selected, a single operation of a shutter button causes two trigger signals to be generated in succession. The generated trigger signal triggers a switching device so that a position of a photographic stop is automatically switched to a position predetermined for the photographic mode, and the photographic light source is caused to emit light a number of times that corresponds to the selected photographic mode. In such a configuration, fundus images are automatically produced a set number of times by a single operation of the shutter. Therefore, a high-quality fundus image can be obtained without concerns that an appropriate moment to capture an image will be missed.

An image forming apparatus includes a communication unit, a prohibition unit, an execution unit, and a control unit. The communication unit communicates with an external apparatus. The prohibition unit prohibits the communication unit from communicating with the external apparatus when a command for executing initialization with respect to the image forming apparatus is specified. The execution unit executes a process for accepting set information of the initialization when the prohibition unit prohibits the communication unit from communication with the external apparatus. The control unit executes a process for informing that the initialization should be executed when an elapsed time of a waiting state where input of the set information is not executed exceeds a given period.

A marine propulsion system includes a transmission mechanism arranged to transmit a driving force generated by an engine to propellers with a speed thereof changed to a low speed reduction ratio and a high speed reduction ratio; a control lever section operated by a user in controlling drive of the engine; and a control portion and an ECU controlling a shift between reduction ratios of the transmission mechanism based on operation of the control lever section by the user. The control portion and the ECU control a shift between reduction ratios of the transmission mechanism based on a transmission control map providing a reference for a shift between reduction ratios of the transmission mechanism taking into consideration an engine speed of the engine and a lever opening of the control lever section. This arrangement provides a marine propulsion system in which both acceleration performance and maximum speed can approach levels that a user desires.
摘要:
A light beam reflected from an ocular fundus 1a is split into a pair of right and left light beams by a two-aperture stop 31 disposed in a position conjugate with an anterior ocular segment 1b of an eye 1 to be examined. The pair of right and left ocular fundus images having a parallax is formed as intermediate images from the split light beams at the position of a photographic mask 43. The optical path of the pair of ocular fundus images formed as intermediate images is split by a pair of optical path splitting lenses 51, 52 disposed in a position substantially conjugate with the two-aperture stop. One ocular fundus image is re-formed on half of an imaging plane 53a of an imaging element 53, and the other ocular fundus image is re-formed separately on the other half of the imaging plane. With such a structure, two ocular fundus images for three-dimensional viewing can be efficiently obtained without using a prism for splitting the optical path.

An outboard motor includes a prime mover, a marine propulsion unit having a propeller arranged to be driven by a rotational force of the prime mover to generate a thrust force, a shift position changing mechanism, a shift position changing mechanism actuator, and a control unit arranged to control the shift position changing mechanism actuator. When the shift position is changed to one of the first shift position and the second shift position from the neutral position, the control unit inhibits a change in the shift position to the other one of the first shift position and the second shift position until a predetermined time period elapses. The above arrangement improves the controllability of a boat propulsion system having an electronically controlled shift mechanism.
