A photographic camera of a type utilizing a roll of film comprises a camera back lid, a take-up spool for taking up the film therearound, and a plurality of switches incorporated in the take-up spool. The switches built in the take-up spool are all closed, when the film is turned around the spool, to generate a signal inidcative of the fact that the film has no doubt been secured to the spool. An electric circuit is also provided for disabling the film wind-up so long as the camera back lid has not yet been closed even though the film has already loaded in the camera.

The camera detects coded perforations of the film at a detecting position for reading out information represented by coded perforations on the film. The camera back cover includes a pressure plate to resiliently abut the film at the exposure station and coacts with film abutting structure to maintain the film flat at a detecting position such that the coded perforations on the film can be read out to generate a film sensitivity signal and two different outputs are provided to indicate whether or not the film is of standard sensitivity and the film sensitivity is displayed. The display modes are changeable.

An electromagnetically driven device has a coil and a plunger movably inserted in the coil between an inserted and ejected positions. An armature carrying a permanent magnet is provided at one end of the coil for holding the plunger in the inserted position by a magnetic attractive force developed between the armature and the plunger when the coil is deenergized. A yoke is provided between the permanent magnet and the armature for establishing a magnetic circuit therebetween with a predetermined reluctance developed between the armature and the yoke.

Exposure indicating devices for use in multi-exposure controlled cameras are disclosed. In the multi-exposure controlled camera, the diaphragm and/or the shutter speed are preferentially preset, that element or factor for governing exposure which has not been preset is automatically controlled. According to the present invention, exposure indicating devices are used to notify the camera operator, prior to exposure, how the shutter speed and diaphragm aperture to be eventually effected will be commensurate with the brightness of an object, according to the controlled lighting of two illuminative indicating members.

An apparatus of spreading a fluid on the floor includes four rectangular application rotating bodies partially overlapping each other, and four nozzles supplying the fluid provided in rotation areas of the respective application rotating bodies. The rotation position of the application rotating body is detected by a light shielding plate and a photosensor. A control portion controls each component so that the fluid is applied onto the floor from a tank through the nozzle by a pump when the application rotating body is not directly under the nozzle. As a result, the apparatus of spreading a fluid on the floor capable of optimally controlling the quantity of the fluid to be applied according to the application condition can be provided.

A single lens reflex camera has a built-in winder which includes a reciprocating member reciprocatable in response to forward and reverse rotations of a motor for automatic charge-up of the camera mechanisms as well as for automatic film wind-up.A charge-type drive mechanism has a charge member which is pushed by the reciprocating member upon the forward movement of the latter due to the forward rotation of the motor to move forward for causing the charge-type drive mechanism to store a driving force.The reciprocating member retracts from the charge member upon its return movement so as not to impede return movement of the charge member. An operation mechanism such as a shutter is operated for photographing under the driving force stored in the charge-type drive mechanism, accompanying return movement of the charge member. A film advance mechanism advances a film in response to the return movement of the reciprocating member due to the reverse rotation of the motor. Furthermore, clutch mechanisms interlocked with a manual selection member are capable of connecting the motor to a film rewinding shaft while disconnecting the motor from the reciprocating member, so that automatic film rewinding is also made possible.

The method of this invention for producing electrolyzed water containing ozone employs an apparatus for producing electrolyzed water from a liquid. The apparatus has two plate electrodes facing each other, a D.C. power source for applying a D.C. voltage across the electrodes and a control circuit for changing a polarity of the electrodes alternately. The method includes the step of producing electrolyzed water by changing the polarity, while a liquid is caused to flow in a flow passage between the electrodes, and the polarity is changed at an interval of time T as defined by formula (10): 0.5≦T≦(1/3)×(L/V) (10) wherein; V: Velocity of flow of the liquid in the flow passage (cm/sec.), and L: Length of the electrodes as measured in the direction of flow of the liquid (cm).

A running member is attached rotatably to a body member, and a working member is attached movably to the body member. Therefore, in a large area, a work can be carried out efficiently even in a corner portion, and a desired work can be implemented even in a narrowed portion by shifting the working member to a working area and directly operating the working member in the narrowed portion.

A single lens reflex camera is provided with a reflex mirror actuating mechanism and automatic diaphragm control mechanism, with each mechanism being delayed to operate at a proper speed. The diaphragm control mechanism arrests operation of a diaphragm driving means during stopping down of the diaphragm by means of an electromagnet actuated in response to the output of a diaphragm control circuit which compares set exposure factors with the brightness of an object to be photographed, while measuring the brightness through the diaphragm aperture that is being driven.
