A white balance adjusting device includes a rotational color filter and a shutter which are provided between a photographing optical system and an electro-developing recording medium having first, second, and third recording areas. Red, green, and blue images are recorded in the first, second, and third recording areas through the rotational color filter. A photometry sensor is provided behind the electro-developing recording medium to sense the intensity of light passing through the first, second, and third recording areas. When the sensed light reaches a proper photometry value, the application of a voltage to the electro-developing recording medium is stopped, and the shutter is closed.

An image reader reads an object image recorded on a flexible light-transmissible recording medium formed in the shape of an elongated web. A curved guide member guides the recording medium, and has at least an arcuate portion formed as a light-transmissible area. A light source is provided at one side of the arcuate portion, for illuminating the object image with light rays emitted from the light source. An image sensor is provided at the other side of the arcuate portion, and is aligned with the light source to receive the light rays passing through the object image. Thus, the image sensor optically and electronically senses the object image. A drive mechanism moves both the light source and the image sensor along the arcuate portion so that the object image is scanned with both the light source and the image sensor.

A reading operation control device provided in an electro-developing type camera using a recording medium which electronically develops an image formed by a photographing optical system. When an electro-developing recording medium is mounted, it is determined whether or not the electro-developing recording medium has been recorded. If the electro-developing recording medium has not been recorded, and when a record mode is set and a release switch is turned ON, a recording operation is performed, and thus an image is recorded in the electro-developing recording medium. If the electro-developing recording medium has been recorded, and then a reading mode is set and a scanning switch is turned ON, a reading operation is performed, and thus the image recorded in the electro-developing recording medium is read.

A pulse signal shaper supplying a pulse signal having a stable pulse width, including an input circuit that produces a first pulse signal in response to an input signal, a delay circuit that produces a second pulse signal obtained by delaying the first pulse signal by a predetermined time, and a signal mixing circuit that is connected to the input circuit and the delay circuit. The mixing circuit combines the first pulse signal and the second pulse signal to produce a third pulse signal having a pulse width equal to or greater than a delay time provided by the delay circuit, and supplies the third pulse signal as an output signal from the pulse signal shaper. In a preferred embodiment, the input circuit includes an oscillator responsive to the input signal. When the input signal has a higher frequency than a predetermined frequency, the input signal is supplied as the first pulse signal at a frequency equal to te frequency of the input signal. When the input signal has a lower frequency than the predetermined frequency, the first pulse signal is supplied at the predetermined frequency.

A format operation control device performs a simple format operation and a standard format operation for a recording medium having a control data area, storing file control information, and a record data area, storing record data. The control data area and the record data area have sectors. In the simple format operation, the control data area is initialized and bad sectors are not detected from each of the sectors of the recording medium. The standard format operation includes a substitution process and a bad sector mapping. In the substitution process, the control data area is initialized, bad sectors are detected from each of the sectors of the recording medium, and a physical format is performed so that good sectors are used instead of bad sectors. In a bad sector mapping, the control data area is initialized, bad sectors are detected from the record data area, and a bad mark is recorded in the FAT-table corresponding to the cluster containing the bad sector.

A bearing mount assembly is installed in opposed relation to a roll support frame with the pass line interposed therebetween, the bearing mount assembly being provided with bearings capable of removably supporting the front ends of roll shafts carried on the roll support frame. In roll exchange operation, the bearing mount assembly is moved away from the roll support frame and has its bearings removed therefrom, whereupon the bearing mount assembly is turned from this raised position to a flat position to provide a roll exchange operation space defined above the bearing mount assembly, making it possible to effect roll exchange operation.

A signal processing device has a memory in which a digital image signal is stored, and a data bus including a plurality of signal liens is connected to the memory. A pull-up resistance is connected to a predetermined signal line, and the other signal lines are connected to the ground through pull-down resistances. A blanking signal BLK3 at a low level is inputted into an output enable terminal of the memory, so that the output terminal of the memory becomes high-impedance, and thus a digital signal corresponding to a pedestal level is outputted through the data bus and a blanking period is formed. The pedestal level is determined by the position of the pull-up resistance.

Spherical fine particles of colored resin are provided. The fine particles are of a spherical shape and are superior in heat resistance, solvent resistance, and chemical resistance, and sufficiently satisfactory in durability and coloring, and industrially advantageous. The spherical fine particles of colored resin are made by incorporating an amino resin cured matter and an inorganic pigment into one body, and a ratio of the inorganic pigment against a total amount of the amino resin cured matter and inorganic pigment is in a range of from about 1 to 30% by weight.

A circuit and method for controlling an output current balance for parallel driven PWM-type digitalized power inverting units are disclosed in which a feedback control such that rising edge times and falling edge times of a PWM waveformed pulse train signal to be supplied to the parallel driven power inverting units are respectively corrected using independent correction signals is carried out to eliminate a deviation between output currents of the parallel driven power inverting units. The correction of the rising edge times and falling edge times is such that a phase advance correction for the one unit with respect to an offset value delay and a phase retardation correction for the other unit with respect to the offset value delay are carried out so that a delay of an average output current with respect to the PWM waveformed pulse train signal is made constant. In addition, if an integration calculation of the feedback control is carried out during a constant period of time upon a change in the PWM waveformed pulse train signal to suppress an abnormal integration. Ripple components due to a generation of output current unbalance can be suppressed by limiting the corrections to the falling edges and rising edges of the PWM pulse train signal to either one according to a polarity of the deviation between the output currents of the power inverting units.
