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 data processing device contains art execution circuit and a data buffer circuit which stores one or more commands and/or one or more parameters which are prefetched, until each of the commands and parameters is read out by the execution circuit. The execution circuit inputs the oldest command stored in the data buffer circuit when an execution of a preceding command is completed, inputs one or more parameters stored in the data buffer circuit when the command input therein requests the parameters, and executes the command input therein, using the parameters when the parameters are input therein. The device further contains a circuit for detecting whether or not there is enough vacant space in the data buffer circuit in which a further command and/or a parameter can be stored, and another circuit for detecting a state of the data buffer circuit in which state the data buffer circuit does not store data including a command and/or a parameter, which is necessary for a next operation in the execution circuit. A prefetch control circuit, provided in either in the device or outside of the device, starts the prefetch operation and continues successive prefetch operations when the second state is detected, and stops the prefetch operation when the first state is detected. The system using the device contains a memory which stores the commands and parameters in the order of execution in the execution circuit.

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.

摘要： When vibration is entered on a vibration transmitting tablet, the vibration is sensed by vibration sensors attached at four corners of the tablet. When this is done, a time delay from entry of the vibration to detection thereof is measured, and the distance between each sensor and the source of the vibration is calculated in dependence upon the time delay. At this time the vibration sensors also sense reflected waves resulting from reflection of the vibration at the end face of the tablet. The larger the angle of reflection, the greater the magnitude of the reflected waves sensed. Accordingly, sensors most likely to sense reflected waves are excluded from calculation, and coordinates are calculated based upon vibration sensed by the remaining sensors only. As a consequence, a discontinuity in coordinates occurs at the boundary of a region decided by whichever of the sensors are excluded. For this reason, a weighted mean is computed of a set of coordinates calculated based upon data obtained from a set of a plurality of sensors, and the value of the weighted mean is adopted as the coordinates sought.
