A plurality of lens groups are moveable in the direction of an optical axis. A plurality of motors are provided for the lens groups, respectively. A driving circuit drives the motors. A switching section sequentially selects the motors and connects the selected motors to the driving circuit. A lens position-detecting section detects the positions of the lens groups. A driving control section sequentially drives the lens groups in accordance with intermediate target position data, respectively, via the switching section and the driving section, and determines whether the lens groups have reached their respective intermediate target positions, on the basis of the detection performed by the lens position-detecting section. When the driving control section determines that the lens groups have reached their respective intermediate target positions, it demands next intermediate target positions, which are slightly away from the initially-determined intermediate target positions. On the basis of the next intermediate target positions, the lens groups are driven again. With this operation repeated, the driving control section controls the driving of the lens groups until these lens groups reach their respective final target positions.

A camera system comprises by a camera main body and a film loaded in the camera main body and having a magnetic recording portion. Data for commanding a printer apparatus to perform trimming exposure is recorded on the magnetic recording portion of the film in advance. A feed mechanism feeds the film. A manual operation member is arranged on the outer surface of the camera main body. In the camera main body, a permanent magnet moves, upon manual operation of the manual operation member, between a position where the magnet opposes the magnetic recording portion of the film and a position to which the magnet is caused to retreat from the magnetic recording portion. When a film feed operation is performed by the feed mechanism while the permanent magnet is set at the position where it opposes the magnetic recording portion, the permanent magnet erases the trimming command data recorded on the magnetic recording portion, thereby prohibiting the printer apparatus from performing trimming exposure.

There is provided a reduced-pressure distillation system, which is relatively simple in construction, easy in operation without depending only on driving of a vacuum pump, and therefore can be manufactured and operated at low costs. The system includes an impure water tank, a separating tank, a drainage tank, and a collecting tank. The impure water tank, the drainage tank, and the collecting tank each has an outside pressure communicating chamber, which makes contact with outside pressure, and a cell, which communicates with the outside pressure communicating chamber corresponding thereto and is sealed with respect to the outside pressure during operation of the system. The separating tank is sealed with respect to outside pressure and has an evaporator provided therein. Impure water is fed from the cell of the impure water tank to the evaporator, by using an effective head between levels of the impure water in the impure water tank and priming supplied to the drainage tank. Remaining water in the evaporator is discharged to the cell of the drainage tank. Purified water in a bottom portion of the separating tank, which is obtained by evaporating the impure water by activation of the evaporator, is collected into the cell of the collecting tank. The cells of the respective tanks communicate with each other via the separating tank. Evacuation within the separating tank is carried out to keep each cell in a pressure-reduced state.

In a display apparatus of a camera according to this invention, an imaging device repeatedly images an object to be photographed and generates a two-dimensional luminance signal. A one-dimensional pattern signal is repeatedly generated from the two-dimensional luminance signal for at least one of inside or outside the imaging device. Each time a new pattern signal is generated, the immediately preceding pattern signal is stored in a frame memory. After the immediately preceding pattern signal is stored in the frame memory, a CPU performs a correlation arithmetic operation between a new pattern signal and the immediately preceding pattern signal stored in the frame memory. The CPU detects a moving amount of the object to be photographed according to the movement of the camera during the repetition time period, and performs the correlation arithmetic operation each time the frame memory stores an immediately preceding pattern signal. In accordance with the moving amount arithmetically operated by the CPU, the moving amount of the object to be photographed is displayed on a display unit in a finder using the width of a photographing picture as a basic unit.

To enable the user of the camera to select, using a simple mechanism, one of a function for simultaneously performing photographing and electronic image pickup, and a function for performing only one of the photographing and the electronic image pickup, the camera incorporates a release button at a position which, for example, the index finger of the right hand can reach, and another button, i.e. a digital button, at a location which the thumb of the right hand can reach. The camera is operated in accordance with a predetermined control program so that the above-described operations can be selectively executed by appropriately operating the release button and the digital button. In other words, the invention provides a camera that permits the user to easily select, using only one hand, only electronic image pickup, only film exposure, or simultaneous execution of both the operations.

The present invention relates to a conveyor adapted to operate by utilization of magnetic wheels and more particularly to a conveyor wherein the power from a drive source in transmitted to a large number of rollers through magnetic wheels capable of affecting the power transfer in a non-contact manner under the action of magnetic force, whereby the rollers constituting a conveyance surface are driven to perform a simultaneous multi-shaft rotation. According to this construction, the generation of noise is suppressed and mechanical wear, rising of dust and damage are prevented. Further, it is possible to prevent the interference of magnetic forces induced inevitably between adjacent magnetic wheels and hence possible to avoid malfunction of the magnetic wheels.

A camera has a rotary operation member, a detection unit, a photographing data setting circuit, and a pulse signal generation unit. The rotary operation member is exposed from a plurality of portions of the camera to be able to be operated from a plurality of directions. The detection unit detects a rotation of the operation member from a predetermined portion and generates a detection signal. The pulse signal generation unit generates a pulse signal in accordance with rotation of the rotary operation member. The photographing data setting circuit sets predetermined photographing data in accordance with the detection output from the detection unit on the basis of the pulse output from the pulse signal generation unit, thus setting and storing a plurality of photographing data.

A diaphragm controller for a camera of the program type which determines a reduced aperture in accordance with the brightness of an object being photographed and effects a diaphragm control based on an exposure period corresponding to the reduced aperture by measuring the amount of object light passing through the reduced aperture, compares a photometric output of light passing through an aperture during the aperture reducing operation and an output which is obtained by calculating an output which varies during the aperture reducing operation so as to satisfy a predetermined program characteristic and controls an aperture value based on the program characteristic when the photometric output and the calculated output coincide.
