Abstract: PURPOSE:To obtain a disk rotation driver which facilitates the easy replacement of a glass disk and has a disk fixing mechanism having a wide recording area by fixing both center hole and inner circumference part of the disk by means of a mechanism having a direct centering mechanism and a fixing mechanism of the disk and a rotary shaft. CONSTITUTION:The inner diameter of the glass disk 21 is put into a shaft 23 of a fitting part having a size equal to a gap of about 0.1-0.2mm. of a revolving shaft 22, and the elastic rubber 24 is attached into a screw shaft 25 at the upper part of the disk 21. A nut 26 engages with the shaft 25 to give uniform deformation to the rubber 24 in a radius direction and perform the centering of both the inner diameter of the disk 21 and the shaft 22. A nut 27 is fixed above the nut 26 via the rubber 28 so that the disk 21 is pressed to the flange surface 29 of the shaft 22. The shaft 22 is attached onto a bearing 34 via a roll bearing 30 and driven by a motor 33. Thus the uniform deformation is secured with the rubber, and the accurate coincidence is obtained between the centroid position and the center position of the inner diameter of the disk 21. Furthermore the recording area is increased requiring no holder.

IPC: G06F3/153
Filed: 1990-03-19
Abstract: PURPOSE:To exactly photograph the color of an object to be photographed even if a photosensitive characteristic of a film is not uniform by a color at the time of taking a hard copy by mixing each color of R, G and B in a prescribed ratio at every color thereof. CONSTITUTION:To each terminal of R, G and B, each color signal of red, green and blue is supplied, and they are supplied to matrix circuits 11 - 13. Subsequently, in each matrix circuit 11 - 13, at every color of R, G and B, other color is mixed independently in a prescribed ratio. For instance, the circuit of a red signal mixes some green and blue signals to the red signal and corrects a red color, and therefore, in an attenuator 11a for the red signal, attenuation scarcely exists, and in other attenuators 11b, 11c for a green color and a blue color, the attenuation is large, and its attenuation is determined suitably in accordance with the correction quantity. In such a way, even if a color photosensitive characteristic of a film is not uniform, a photographed color comes to reproduce faithfully a color of an actual object to be photographed.
