    摘要: A coordinate input apparatus having a stable and good input sense irrespective of different input conditions such as a vibration input position, a pen pressure and a pen angle. The coordinate input apparatus acquires an input coordinate in accordance with a delay time required for vibration input from a vibration input pen to a vibration propagation plate to reach a vibration sensor. A controller of the apparatus drives the vibration input pen at a first drive level. A window signal generator of the apparatus generates a window signal indicating that a significant signal was detected, when the level of an envelope detected from a signal supplied from the vibration sensor exceeds a detection threshold value. In accordance with the window signal, delay times tp and tg are acquired. A level discriminator of the apparatus judges whether the level of the envelope exceeds a discrimination threshold value. If it is judged that the level exceeds the discrimination threshold value, the controller drives the vibration input pen at a second drive level lower than the first drive level to acquire the delay times tp and tg.

    摘要: Continuity of coordinates between areas of a coordinate input surface which is divided into a plurality of areas is maintained. In inputting "A, B, C" on a coordinate input plate, when an input operation is started from an initial point, area is determined as an input area, and vibration delay times are measured by using sensors, thereby calculating a coordinate value. When the input operation is continued up to a terminal point, the input point shifts to area. However, vibrations are detected by using the same sensors to calculate a coordinate value as long as the input operation is continuously performed. With this operation, since sensors are not changed for the respective areas, discontinuity of lines at the boundaries between the areas can be prevented.

    摘要: The invention aims to provide a coordinate input apparatus having high detection reliability and high efficiency and to control the influence of ambient light using a simple structure. The apparatus detects a light spot flashing on and off in a predetermined cycle and incident at a desired position on a coordinate input screen, and includes a detection device having photoelectric conversion elements corresponding to N pixels for detecting a light spot coordinate. The difference between signals from photoelectric elements in light emission state and in light non-emission state at each N pixel is found, and the smaller of the difference signals of the m-th pixel having the maximum difference signal is set as a threshold value. Effective pixels are identified based on the threshold value, and the coordinate is calculated by using the difference data of the selected effective pixels.

    摘要: A cap covering a light-emitting element attached to the distal end of an indicator is held by a sliding member, and is slidably attached axially along the indicator. By pressing/separating the cap against/from a coordinate input surface, a tact switch operates interlockingly with the cap to switch driving control of the light-emitting element. For example, the light-emitting element is driven by pressing the cap, and driving of the light-emitting element is stopped by separating the cap. Since the cap covers the light-emitting element, the light-emitting element can be prevented from being worn and scratched. Driving control of the light-emitting element need not be additionally switched, resulting in high operability.

    摘要: A coordinate input apparatus which can attain an accurate coordinate input operation, includes a sensor for detecting an input variation. The vibration is amplified, and an envelope detection circuit generates the envelope of the amplified vibration. A gate signal generation circuit receives the envelope and a second-order differential signal of the envelope generated by an inflection point detection circuit. The gate signal generation circuit attenuates the envelope and adds a predetermined offset to the attenuated envelope. The gate signal generation circuit compares the sum signal with the second-order differential signal to generate a gate signal. In the duration of the gate signal, a tg comparator detects, as a group delay time, a time up to the zero cross point of the second-order differential signal, and a tp comparator detects, as a phase delay time, a time up to the zero cross point in a predetermined order of a phase signal. An arithmetic control circuit calculates the coordinate position of a vibration input source on the basis of these delay times.
