Title: Input device and input processing method of input device
Inventor: YUASA EISUKE
IPC: G06F3/041
Filed: 2019-09-26
Abstract: To provide an input device which can adjust sensitivity of a touch panel properly, without requesting troublesome operation to a user.SOLUTION: An input device has a storage unit 11 which stores a touch panel sensitivity value 61 for adjusting an input capacitance value 73 of a touch panel 72 and an input threshold value 63 for determining whether or not touch operation is performed. An input error for the touch operation of the touch panel 72 is determined by comparing the input capacitance value 73 with the input threshold value 63. When the input capacitance value 73 is smaller than the input threshold value 63, the touch panel sensitivity value 61 is corrected so that an adjustment input capacitance value 62 to be adjusted may be close to the input threshold value 63. Then, the adjustment input capacitance value 62 is generated by multiplying the input capacitance value 73 and the touch panel sensitivity value 61. The input error is determined by comparing the adjustment input capacitance value 62 with the input threshold value 63.SELECTED DRAWING: Figure 1

Title: Printer and printing method
Inventor: ICHIOKA YOSHIKAZU
IPC: B41J2/01
Filed: 2019-09-27
Abstract: To improve the printing quality by preventing the excessive correction even when temporal variations are generated in a deviation amount.SOLUTION: A chart for deviation amount detection for a continuous sheet WP is formed and an imaging unit 17 images the chart for deviation amount detection. An image processing unit 27 calculates a deviation amount smaller than the maximum deviation amount at an absolute value as a correction value on the basis of a variation locus of a density peak position from image data equivalent to the chart for deviation amount detection imaged by the imaging unit 17. A control unit 25 corrects a printing timing with the correction value. Therefore, since the correction value is calculated on the basis of the deviation amount smaller than the maximum deviation amount at the absolute value even when temporal variations are generated in the deviation amount within a prescribed length, the excessive correction can be prevented to improve the printing quality.SELECTED DRAWING: Figure 1
