    • Y coil Y1 is mounted on the attachment panel 24 so that its long sides Y1f and Y1g follow the front surface 24n, and is bent at a first edge 24a1 onto an edge surface 24a, and is further bent at a second edge 24a onto a rear surface 24b. Even if the pen moves to near an edge portion of the writing surface, the signal generated by long sides Y1f, Y1g will have a little influence from a signal generated from the short side Y1d. When the X coordinate calculated in S1306 is judged to be a coordinate in the X axis edge (S1308:YES), then an X axis edge flag is set in S1310 and a correction coefficient K that corresponds to the distance of the pen from the edge of the Y coil is extracted in S1312 by referring to a correction table. When the Y coils are scanned in S1314, if the X axis edge flag is judged to be set (S1316:YES), then in S1318, all of the values detected for the Y coils in S1314 are multiplied by the correction coefficient K. In S1320, the Y coordinate is calculated based on the corrected detected values. With this configuration, the error caused by influence from the short sides of the Y coils can be corrected so that the Y coordinate can be accurately obtained.
    • Y线圈Y1被安装在安装面板24上,使得其长边Y1f和Y1g跟随前表面24n,并且在第一边缘24a1处弯曲到边缘表面24a上,并且在第二边缘24a进一步弯曲到后部 表面24b。 即使笔移动到写入表面的边缘附近,由长边Y1f,Y1g产生的信号也将从短边Y1d产生的信号产生一点影响。 当在S1306中计算的X坐标被判定为X轴边缘的坐标时(S1308:是),则在S1310中设定X轴边缘标志,并且对应于笔从边缘的距离的校正系数K 通过参照校正表在S1312中提取Y线圈。 当在S1314中扫描Y线圈时,如果判断X轴边缘标志被设置(S1316:是),则在S1318中,将S1314中的Y个线圈检测的所有值乘以校正系数K. S1320,基于校正的检测值计算Y坐标。 利用这种结构,可以校正由Y线圈的短边的影响引起的误差,从而可以准确地获得Y坐标。

    • When there exist two X coils that generate voltages of the same values during the X coil-scan operation (yes in S314), the CPU 56 discards the position coordinate table 58a that is already stored in the work area, and reloads a new position coordinate table 58a from the ROM 58, and then stores the position coordinate table 58a in association with the pen attribute data that is detected in S310. Then, the CPU 58 calculates a ratio r between the detected value d and the reference value g in S318, and multiplies, with the ratio r, each voltage difference value DIFF in the reloaded position coordinate table 58a in S320. As a result, the position coordinate table 58a is corrected in correspondence with the lowering of the output level of the alternating magnetic field of the pen 60. The CPU then calculates the X coordinate based on the corrected position coordinate table 58a.
    • 当在X线圈扫描操作期间存在产生具有相同值的电压的两个X线圈时(S314中为“是”),CPU56丢弃已经存储在工作区域中的位置坐标表58a,并重新加载新的位置坐标 从ROM58中读出表58a,然后与S310中检测到的笔属性数据相关联地存储位置坐标表58a。 然后,CPU38在S318中计算检测值d与基准值g之间的比率r,并且与比率r乘以S320中的重新加载位置坐标表58a中的每个电压差值DIFF。 结果,对应于笔60的交变磁场的输出电平的降低来校正位置坐标表58a。然后,CPU基于校正位置坐标表58a计算X坐标。

    • An exposing device for scanning a photosensitive drum with a laser beam includes a laser beam emitter, a polygonal mirror, a mirror motor and a controlling unit having a timer circuit. The laser beam emitter emits a laser beam based on information of an image. The polygonal mirror deflects the laser beam emitted from the laser beam emitter to the photosensitive drum. The mirror motor rotates the polygonal mirror. When the exposing operation is executed, the controlling unit drives the mirror motor and the laser beam emitter. The photosensitive drum is thus scanned by the laser beam and is exposed. The controlling unit stops the driving of the laser beam emitter when the scanning of the photosensitive drum is finished. The controlling unit continually drives the mirror motor during a predetermined time from the end of the scanning of the photosensitive drum. The controlling unit stops the driving of the mirror motor after the predetermined time passes.
