Title: Lens driving device
Inventor: MASUDA HIDETOSHI
IPC: G03B5/00
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To accurately detect the absolute position of a lens without complicating constitution by allowing a lens position detecting means to set the peak value of a detection signal; level within the moving range of the lens being a position detecting object. SOLUTION: Since an output signal f within driving ranges from a point A to a point O (region W) and from the point O to a point B (region T) out of the driving range from the point A to the point B is changed from a level KVC to a level GND, the resolution of an encoder is double that in the conventional device in the case of using an A/D converter having the same accuracy. Namely, since the quantization unit of detected voltage is all the same, the lowering of reliability caused by external noise is prevented. Though the detecting resolution is doubled, the position of the leans and the signal f shows one-to-two correspondence, so that the regions W and T are not distinguished from each other only by the signal f, and the position of the lens is not specified.  Therefore, when the gradient of the signal f is positive in the midst of driving the lens in a telephotographing direction (right direction in the figure), the lens is known to be in the region W, and on the contrary, when it is negative, the lens is known to be in the region T.

Filed: 1983-02-28
Abstract: PURPOSE:To improve the accuracy of character reading by providing the 1st and 2nd recognizing sections and discriminating and outputting the final answer based on a preset statistical data for recognition from each result of recognition. CONSTITUTION:Suppose that an input pattern is (a), the result of recognition R1 of an ANK recognizing section 2 is (a) and the result of recognition R2 of a Kanji (Chinese character) recognizing section 3 is ryo. A discriminating circuit 4 references a discriminating table and reads reference data SA, SB of an address designated by an answer (a) of the result R1. Further, the data SA, SB are compared with the value of similarity of the result R1 and the difference of similarity of the result R2 respectively. In this case, when the value of similarity is 90 and the difference of the similarity is 20, since the values exceed the threshold values SA, SB (80, 15), the circuit 4 discriminates the (a) being the answer of the result R1 of the recognizing section 2 as the final answer and outputs it. When the values of the results R1, R2 are smaller than the data SA, SB respectively, the recognizing section 3 outputs ryo being the answer of the result R2 as the final answer.

Title: Copying machine
Inventor: NOGAMI YUTAKA
IPC: G03G15/00
Filed: 1987-02-18
Abstract: PURPOSE:To preclude blurring, etc., due to the disorder of a transfer image by setting the form conveyance distance from an image transfer part to a fixation part 1 longer than the conveyance-directional length of a recording form which is usable for a copying machine. CONSTITUTION:A transfer corotron 5 charges the recording form 14 electrostatically at a transfer part to move toner to the surface of the recording form 14, and the transfer is completed. Then the recording form 14 after the transfer is completed is separated by a separating corotron 6 from a photosensitive drum 1 and then conveyed by a form conveying means 12 to a fixing roll 13. Then the distance A between the transfer part and fixing roll 13 is set longer than the conveyance- directional lengths of plural kinds of recording forms 14 and used for the copying machine. Therefore, when the conveyance-directional front end of the recording form 14 is clamped by the fixing roll 13, the transfer of the rear end of the recording form 14 is already completed, so the disorder of the transfer speed is eliminated even if there is a speed difference generated among the peripheral speed of a photosensitive drum, the conveying speed of a form conveying means, and the peripheral speed of the fixing roll. Consequently, an excellent copy image which has no disorder such as blurring is obtained.
