An information managing apparatus for managing received electronic mail has a memory for successively storing entered electronic mail, a CPU having a program for managing the electronic mail stored by the memory, a display unit for displaying electronic mail managed by the CPU, and a tablet for making an entry relative to the electronic mail displayed by the display unit. The tablet allows the user to establish a retention period with respect to the displayed electronic mail. The CPU stores the electronic mail with the retention period added thereto in the memory and deletes the electronic mail with the added retention period which has expired as detected by comparison with a timer at a given period of time.

Method and apparatus for setting retention period of e-mail based on

A hand-written character recognition apparatus which checks the relation between the rectangular outline directions of two partial structures of one character.

Hand-written character recognition apparatus

A touch panel apparatus of the type in which a plurality of photo-detecting pairs generate a plurality of detecting beams which cross the display surface and including a circuit for reducing the sensitivity of the photo-detecting pairs at the corners of the display surface to prevent malfunction due to reflected beams caused by the relatively higher intensity beams at those locations resulting from the relatively shorter beam lengths

Touch panel apparatus

A character recognition apparatus is comprised of an input device for obtaining hand-written informations, a character dictionary memory for storing characteristics of characters and symbols, a character recognition device for determining character or symbol of the hand-written informations in association with characteristics of characters and symbols stored in the character dictionary memory, a group table memory for storing group tables of characters and symbols, a display device for displaying thus recognized character or symbol and associated character or symbols, if the recognized character or symbol is registered in the group table memory and a device connected to the group table memory for changing group tables of the group table memory.

On-line character recognition apparatus

A hand-written character recognition apparatus and method in which line element data obtained from an output hand-written stroke is converted to a plurality of sub-strokes satisfying a tracing condition in accordance with a tracing command described in a character dictionary data base, substrokes satisfying the tracing condition are selected in accordance with a selection command described in the character dictionary data base, then on the basis of an assumption that the hand-written stroke is a set of sub-strokes, the hand-written character is recognized by evaluating the shape of the sub-stroke by employing a shape evaluation command and by evaluating a position evaluation command derived from the character dictionary data base, whereby a hand-written character, such as a distorted hand-written character and so on, can be recognized with ease.

Hand-written character recognition apparatus and method

A hand-written, on-line character recognition apparatus, and the method employed by it, in which the structure of a dictionary for recognition is formed as a sub-routine type, whereby the dictionary can be made small in size and a time necessary for recognition can be reduced.

A coordinate position digitizing system comprises a position determining plate having a plurality of first conductors extending in parallel with one another at regularly spaced intervals. A plurality of second conductors also extend in parallel with one another at regularly spaced intervals and across the first conductors. Driving and controlling means are provided in common to the first conductors and the second conductors for selectively energizing in turn one or more of the first conductors and second conductors, for example, by supplying a direct current flowing therethrough. Pick-up means, such as a magnetic flux detecting means, is movably set on the position determining plate for producing a signal in response to field variations on the position determining plate caused by the selective energization of the first conductors and second conductors. Information producing means produces positional data defining a position on the position determining plate to which the pick-up means is brought close, based on the strength of the signal drived from the pick-up means.

A coordinate position digitizing system to be used with a cathode ray tube, comprises a position determining plate having a plurality of conductors extending parallel with one another at regularly spaced intervals, and driving means for supplying a constant current selectively to the conductors, one after another, within a horizontal scanning period of the cathode ray tube. Magnetic flux detecting means detects magnetic flux on the position determining plate, and a band pass filter eliminates a noise component resulting from the deflection magnetic field of the cathode ray tube. Positional data defining a position of the magnetic flux detecting means on the position determining plate is produced in response to the output of the band pass filter.

A coordinate position digitizing system incorporates apparatus for detecting the X and Y positions of a voltage detecting device relative to a position determining plate employing apparatus for generating data corresponding to the X and Y positions of said voltage detecting device on said plate at successive sampling times, means for calculating the difference corresponding to the difference in the indicated position at two successive sampling periods, and rejecting signals indicating positions which differ from previous positions by distances which are greater than a predetermined amount, corresponding to the maximum distance that the voltage detecting device can be moved between successive sampling periods. In this way, position-indicating signals which are corrupted by noise pulses or the like are rejected.

A coordinate position digitizing system comprises a position determining plate having a plurality of first parallel strip electrodes provided on one surface of a insulating layer to form plural groups thereof each connected in common and a plurality of second parallel electrodes each having the width wider than that of each of the first electrodes and provided on the other surface of the insulating layer to extend in the direction perpendicular to the first electrodes, a detecting electrode provided to face to the surface of the insulating layer on which the first electrodes are provided and connected through a predetermined capacitance to a reference potential point for producing a signal in response to a voltage obtained thereat, driving and controlling means for supplying with a constant voltage selectively to the groups of the first electrodes one after another during a first period and also supplying with the constant voltage selectively to the second electrodes one after another during a second period, and means for producing positional data defining positions of the detecting electrode on the position determining plate in both the direction of arrangement of the first electrodes and the direction of arrangement of the second electrodes in response to the signal derived from the detecting electrode.
