摘要:
An information apparatus comprises a main apparatus and a subsidiary apparatus which are separable. The main and subsidiary apparatuses has electrical connectors which are connected substantially automatically when the two apparatuses are attached. The connectors are provided with covers which are movable in association with the attaching procedure. Thereby, the connectors can be kept clean and free from dust contamination or breakage, and the reliability of the information apparatus can be enhanced.

Vibration applied to a tablet is sensed by a sensor provided on the tablet and a time delay from generation of the vibration to the sensing thereof is measured, whereby distance from the vibration source to the sensor can be measured. If the vicinity of the leading edge of the envelope of registration is sensed when sensing the vibration, the effects of reflected waves from the periphery of the tablet are reduced. To this end, the envelope is differentiated to detect an inflection point. The peak gain frequency of the differentiating circuit is greater than the frequency of vibration generated by the vibration source. As a result, the phase of the output signal produced by the differentiating circuit is advanced by about .pi./2 with respect to the phase of the input signal, thereby making it possible to sense vibration more quickly.

Some components of a vibration input to an input guarantee region on a vibration transmission plate directly reach a vibration sensor, but some other components are reflected by the end portion of the vibration transmission plate, and then reach the vibration sensor. A vibration suppressor is attached to a peripheral edge of the vibration transmission plate, and is located along the path of the vibration reflected by the end portion of the vibration transmission plate to the vibration sensor. Since the vibration sensor is attached to a corner portion of the vibration transmission plate where no vibration suppressor is attached, a decrease in coordinate detection precision caused by reflected waves can be suppressed, and a compact apparatus can be realized.

Disclosed is a coordinate input apparatus for detecting an input vibration from a vibration pen by a vibration sensor provided on a vibration transmitting plate to measure a vibration transmission time to the vibration pen to detect the input coordinates of the vibration pen on the vibration transmitting plate on the basis of the measurement result. The vibration pen is made wireless by incorporating all mechanisms required to generate the vibration. A drive timing for vibration input from the vibration pen and used as a measurement origin of the vibration transmission time is transmitted to a main body for performing the coordinate detection processing by bringing the vibration pen in temporary contact with the main body.

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.

In the coordinate detection of resistive film system, detection of the coordinates of simultaneously designated two points is made possible. On a touch panel composed of two conductive films, whether input is made in a point or simultaneously at two points is judged by a current monitor. Simultaneous inputs at two points decrease the apparent resistance of the conductive film, and can be detected by an increase in the current. If the input of a point is identified, the coordinate data of the input point are retained as latest coordinate data in a RAM. If simultaneous inputs at two points are identified, coordinate data are obtained from the coordinate data retained in the RAM and from the potentials in the x and y directions, obtained from two conductive films constituting a touch panel, through amplifiers, and are outputted, together with the coordinate data retained in the RAM, as the coordinate data of the two points.

An information apparatus has an input device with a portion to be supported in an information apparatus installing desk. The portion to be supported serves as a contact with an arc-shaped desk in which one point on a ridge line of a casing of the information apparatus is set to a center. A top plate having a concavity which can enclose an information apparatus, an arc-shaped receiving portion for supporting the arc-shaped portion to be supported, and a tilt mechanism for rotating the information apparatus around the center of the arc as a rotational center are provided on the desk side for installing the information apparatus.
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.

An object of the invention is to allow an editing work such as image input and image erasure to be performed easily. Specifically, according to the invention, a size of an image editing area is changed with a motion amount of input coordinates. Therefore, the size suitable for each type of editing process can be set without specific operation instructions, and the editing area having a suitable area size can be designated without interrupting a trace input operation.
