Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Oscillation applied to a tablet is sensed by a sensor on the tablet and a time delay from generation of the oscillation to the sensing thereof is measured, whereby distance from the oscillation source to the sensor can be measured. If this distance is measured for each of a plurality of different sensors, the position of the oscillation source on the tablet can be determined. The measured delay time includes not only time for transmission through the tablet but also an error. Accordingly, the delay time between the oscillation source and a sensor is not used as is, one of the sensors is adopted as a reference sensor and a difference in delay time between this sensor and the oscillation source is used to measure the distance between the oscillation source and each sensor. As a consequence, errors attributable to respective sensors are canceled out so that measurement precision is improved.

Abstract: A vibration transmission plate for inputting coodinates has a two-layer structure with an input layer for inputting vibration and a vibration transmission layer for transmitting the vibration. By using a member having a flexural modulus of elasticity of 180.0-720.0 kgf/mm.sup.2 as the input layer, accuracy in detecting the input position of the vibration can be improved. By forming a member made of glass fibers, which can restrict the direction of the transmission of the vibration between the input layer and the vibration transmission layer as an intermediate layer, the accuracy can also be improved.
