摘要： A piezoelectric sensor for detecting elastic plate vibrations in an object such as the transmission plate in a coordinate input apparatus is prismatic in shape and is fixed to the surface of the object. The prismatic sensor is arranged so that it is parallel to the direction of propagation of the vibrations and has an electrode surface perpendicular to the surface of the object. The arrangement of the prismatic sensor permits the thickness of the object in which the plate vibrations propagate to be substantially reduced and reduces the manufacturing cost of coordinate input apparatus using the prismatic sensor.

摘要： In a pen-input computer or the like, it is impossible to distinguish an input method and to execute a proper process according to the input method. A touch panel driver generates finger-input coordinate values for a display screen. A digitizer driver generates pen-input coordinate values for the display screen. A processor receives the coordinate values and additional information indicative of either the finger-input or the pen-input from a source discriminator, starts an inputting process according to the input method, and allows a virtual keyboard to be displayed onto the screen or allows a “CHR input pad” window to be opened.

摘要： An object of the invention is to provide a coordinate input apparatus which phase-shifts an input signal in accordance with temperature and corrects a phase shift due to a change in temperature, thereby performing coordinate input. A phase shift unit of a temperature phase shift circuit is constituted by connecting two thermistors having the same temperature characteristics and two capacitors having the same capacitance to constitute a bridge circuit. An output (Eout) has a gain of 1 with respect to an input (Ein) and is phase-shifted by tan.sup.-1 [(-2.omega.CR)/.+-.(1-.omega.CR).sup.2)], where R represents a value which exponentially varies in accordance with temperature. For this reason, the output signal can be phase-shifted in accordance with a change in temperature. When this circuit is applied to a coordinate input apparatus using an ultrasonic wave vibration, the phase shift of a vibration due to variations in temperature is corrected, thereby enabling coordinate input stable with respect to changes in temperature.

摘要： A coordinate input apparatus has an effective area in a vibration transmission member for inputting a vibration from a vibration generator and a computing unit that computes the coordinates of the position of the vibration generator on the basis of the delay time between the vibration generation and the detection of the vibrations by a vibration sensor. A vibration proof material is disposed in the periphery of the vibration transmission member to prevent the inputted vibrations from being reflected at the acoustic impedance boundary of the vibration transmission member. The vibration proof material is disposed so that the spacing between the edge of the effective area and the edge of the vibration proof material facing the effective area edge becomes larger with increasing distance along the effective area edge from the vibration sensor.

摘要： With the use of transfer delay of supersonic wave, an apparatus for measuring a distance and inputting coordinates accurately is implement. When a distance is measured with the use of the transfer of supersonic wave, the transfer delay time is measured at the specified portion of a detected signal. The position of the specified portion to be measured may shift due to the level of the detected signal or noise. The signal obtained by delaying the specified time the envelope of the detected signal is generated. The signal obtained by attenuating the envelope at the specified rate and adding the specified offset is also generated. A gate signal is formed by obtaining the differential of these two generated signals. The delay time is measured during the gate period. With this configuration, the gate-period timing is immune to influences of the signal level and noise, providing highly precise coordinate inputs.

摘要： Disclosed is a coordinate input device, having a vibration transmission plate, that simplifies the measurement of a vibration transmission speed, which is used as a known constant to calculate a distance between a vibration input location and individual vibration sensors, and that ensures the accurate performance of calculations to acquire input coordinates. According to the present invention, a vibration transmission plate has anisotropic properties that are associated with two axes. As a result, the speeds at which vibrations arrive at vibration sensors differ depending on which pair of vibration sensors, 6a and 6d, or tb and 6c, is involved. Therefore, the vibration transmission speeds are measured for the individual pairs of vibration sensors, 6a and 6d, and 6b and 6c, and the measured values are stored as known values. These values are employed as constants to be used for calculations performed to acquire coordinates.

摘要： A highly portable information processing apparatus projects a hand-written input image in real time while the projected image is not hindered by the hand-writing operation. An image to be projected is displayed on a transmission type liquid crystal display provided in a main control unit and a light beam is projected from the bottom thereof. The light beam passes through lenses and is projected to a coordinate input plate and reflected thereby, passes through lenses, is reflected by a reflection plate and then projected to a screen. The coordinate input plate allows the viewing of the projected image from a plane opposite to the projection plane so that an operator may point a desired coordinate while watching the image. The pointed coordinate is displayed by a main control unit on the liquid crystal screen as an image. The projected light is not intercepted by an obstacle in a path to projection on the screen.

摘要： A high-precision coordinate input apparatus having a small circuit construction. A vibrating pen transmits vibration onto a vibration transmitting tablet, then vibration sensors provided at corners of the vibration transmitting tablet detect the vibration. One of the vibration sensor is used as a reference sensor. Time difference between vibration detecting timing by this reference sensor and detecting timing by one of the other sensors is measured. This measurement is performed on all the vibration sensors with respect to the reference sensor. The obtained time differences are converted into distance differences for calculation of the coordinates of the position in which the vibration has been generated. The vibrating pen has a power source and it operates independent of the apparatus main body. The vibrating pen changes its frequency of vibration in accordance with the voltage of the power source. The apparatus main body captures this change in the vibration frequency and obtain the state of the vibration pen power source.
