Title: Optical card reader
Inventor: KOBAYASHI SHOEI
IPC: G11B7/004
Filed: 1986-09-30
Abstract: PURPOSE:To quickly access a desired sector by providing a non-recording area having a prescribed length between sectors of optical information recorded on an optical card and detecting and counting non-recording areas and controlling a motor driving circuit based on the counted value. CONSTITUTION:At the time of access, the rotative speed of a motor 12 is so controlled that a CCD line sensor 26 scans once while an optical card 15 is moved for a distance corresponding to one subtrack. If the output of the CCD line sensor 26 is lower than a prescribed level in three scanning sections, the non-recording area is decided, and the output of a counter circuit 4 is set to, for example, the high level. The output of the counter circuit 4 which is set to the high level at each time of passing the non-recording area is counted by a counter circuit 7. When the counted value reaches a prescribed value, the rotative speed of a motor 12 is so controlled that the CCD line sensor 26 scans four times to accurately read data while the optical card 15 is moved for the distance corresponding to one subtrack.

Title: Recording method of reciprocative recording printer
Inventor: MIURA MASAYOSHI
IPC: B41J2/045
Filed: 1987-09-17
Abstract: PURPOSE:To prevent a stripe pattern with a reciprocative printer from occurrence, by a method wherein a pixel corresponding to that on the odd numbered or the even numbered numerated in a scanning direction of a multihead is recorded on a forward path, and the residual pixel is recorded on a reverse path. CONSTITUTION:An image signal is applied to a multihead by using a half clock pulse every other clock pulse so that only a pixel on the odd numbered numerated in a scan direction of a multihead is recorded on a forward path and after ending of recording on the forward path, scan on the reverse path is performed without transferring recording paper as it is. On the reverse path, the pixel corresponding to that on the even numbered which has been not recorded on the forward path is recorded by using the half clock pulse also. Then, the recording paper is sent out, and the same recording on the forward recording as above-mentioned is performed on a new white paper. Consequently, since a dot to be drawn on the forward path and the dot to be drawn on the reverse path are arranged alternately in the scan direction of the multihead, a difference in a recording state between the forward path and the reverse path will be illegible, and a stripe pattern can be easily eliminated.

Title: Facsimile equipment containing dirty alarm function
Inventor: TOBA SEIJI
IPC: H04N1/40
Filed: 1995-09-11
Abstract: PROBLEM TO BE SOLVED: To immediately detect the dirt on an image reading part at the sending side by alarming this dirt when no full white line is detected after actuating a facsimile equipment over a prescribed main scanning line for detection of a full white line. SOLUTION: An image reading part reads and scans all dot images existing on a main scanning line via an image sensor to threshold them every second line and then carries on these reading/scanning operations for the following main scanning lines through the subscanning. If an original includes the written normal characters, etc., a full white main scanning line (nm) always exists including the blank parts of the original characters in addition to a main scanning line (m) containing the black pixels. In other words. if the optical system of the image reading part has dirt, a vertical black line appears on the recording paper, etc., printed out to the opposite party side to cover the highest line through the last one in the moving direction (subscanning direction) of the sending original. Thus the black line is decided as the dirt if it can be extracted out of the original image that is read and scanned at the image reading part.

As a result, it is possible to eliminate unmatching observed from the input terminal 10 due to the provision of the flat plate 2 and the partition plate 3.

Filed: 1992-09-01
Abstract: PURPOSE:To prevent the accuracy of a coordinate position from being lowered by reflected waves. CONSTITUTION:When any vibration is inputted in an effective area A on a vibration transmission board 8, an arithmetic operation/control circuit 1 compares delay time from vibration source of vibrations detected by sensors 6a-6d and among areas Aa-Ad, the area adjacent to the sensor having the shortest delay time is judged as the area where the vibration is inputted. When the vibration from the judged area is reflected by a vibration-proof member and detected by the respective sensors, the coordinate position of the vibration source is calculated based on the vibrations detected by the remaining sensors excepting the sensor which most enlarges the incidental/emitting angle of reflection, namely, which detects a lot of reflected waves.

As gelation begins, the intensity of the scattered light once attains is maximum, then, it settles after reaching the maximum point and becomes flat with a gradual reduction in the hourly change. At the flat part (plateau), the gelation is completed.
