摘要： A touch-type input device (10) includes a touch panel (11). Capacitors (C) are formed at intersections of drive electrodes (12) and sensor electrodes (13) in the touch panel (11). A controller (21) determines whether the touch panel (11) has been touched from data values, each indicating a change amount in the capacitance from a reference value. When detecting from the data values a change in the capacitance to a reverse polarity differing from the polarity when a human body touches the touch panel (11), the controller (21) determines that external noise caused the change and stops detecting touching of the touch panel (11). When the controller (21) detects a change in the capacitance to the reverse polarity, at the same time, the location of where the capacitance of the reverse polarity is detected does not shift, the controller (21) determines that the change in the capacitance is irrelevant to influence of external noise and continues to detect touching of the touch panel (11).

摘要： A capacitive touch panel can select a way of voltage control with a high degree of detection accuracy according to operating environment. In response to approach of an input unit, the stray capacitance of the sensing electrode the input unit approached increases. Accordingly, charge and discharge of the stray capacitances of a plurality of sensing electrodes are controlled, and a sensing electrode the potential change of which is made slow by the increase in stray capacitance and resultant increase in time constant is detected as a sensing electrode the input unit approached. The stray capacitance of a sensing electrode can selectively be controlled either by the charge control or by the discharge control, and optimum one of the controls is selected according to operating environment.

摘要： A capacitance type touch panel is provided which distinguishes a noise signal with ease and detects an input operation position with high accuracy, without extensively modifying the structure of a touch panel. The capacitance type touch panel is provided with capacitance change judgment means for comparing a voltage variation level R(n,m) of a detection electrode S(n) detected by capacitance detection means with a detection threshold value. If the voltage variation levels R(n,m) of all the detection electrodes S(n) are equal to or more than the detection threshold value while outputting a detection signal to any drive area DV(m), it is assumed that noise occurs for the long period of outputting the detection signal to the drive area DV(m), and position detection means does not detect the input operation position.

One of two or more drive electrodes respectively belonging to drive electrode group DV(n) and a drive electrode group DV(n') adjacent to each other is a common drive electrode arranged therebetween. A pitch between the drive electrodes arranged at equal intervals is set so that a change in a detection voltage level R(m,n) appears at a detection electrode S(m) arranged in the vicinity of an input operator when a drive control unit performs drive control of the drive electrode group DV(n) and the input operator is at a position distant from the drive electrode group DV(n) up to an intermediate position of the adjacent drive electrode group DV(n').

摘要： A touch-type input device (10) includes a touch panel (11) including drive electrodes (12) and sensor electrodes (13). Capacitors (C) are formed at intersections of the drive electrodes (12) and sensor electrodes (13). A controller (21) determines whether a conductive foreign matter exists on the touch panel (11) from raw data values indicating changes in the capacitances of the capacitors (C) from initial reference values. The controller (21) determines touching of the touch panel (11) from control data values indicating changes in the capacitances of the capacitors (C) from control reference values changed when a conductive foreign matter exists. When the raw data values indicate existence of a conductive foreign matter, the controller (21) sets the control reference value of each capacitor (C) to a raw data reference value corresponding to the present raw data value. The controller (21) updates the initial reference value when the touch-type input device (10) is activated and updates the control reference value when the control reference value is erroneous.

摘要： Changes of the stray capacitances of a large number of sensing electrodes can be detected simultaneously. Further, even if a stray capacitance changes slightly, an input operation to a sensing electrode can be detected based on elapsed time until the electric potential of the sensing electrode becomes the same as a threshold potential. The stray capacitance of a sensing electrode and a resistor of the sensing electrode form a CR time constant circuit. Charge or discharge of the stray capacitance of the sensing electrode is controlled while a rest time in a predetermined time ratio is set. A stray capacitance that slightly increases in response to an input operation made near a sensing electrode can be detected by detecting the stray capacitance in extended elapsed time until the electric potential of the sensing electrode becomes the same as the threshold potential.

摘要： The present invention provides a pulse modulating method which ensures demodulation of bit data without being affected by a change in the pulse width and permits high-speed transmission, pulse modulating equipment for the pulse modulating method and pulse demodulating equipment. The pulse modulating equipment divides an input signal into n-bit words and converts it into a pulse unit signal which represents the state of the bit data for each word by time intervals i and j between odd-numbered transitions and between even-numbered transitions. The respective time intervals i and j are free from the influence of the transmission line used, for example, and remains unchanged in the pulse demodulating equipment, so that no demodulation error arises. Further, since the bit data is represented by the time intervals i and j between the odd-numbered transitions and between the even-numbered transitions, the coding efficiency increases, permitting high-speed transmission.
