摘要： A touch panel input apparatus has a touch panel which consists of X- and Y-direction electrode panels. When the apparatus is in a power-off state, one end of the X electrode panel is intermittently connected to a power source and one end of the Y electrode panel is intermittently grounded via an output resistor, in response to control signals outputted from a sampling circuit. In this state, synchronously with a clock signal, the sampling circuit performs sampling of a voltage developed across the output resistor when the two electrode panels are brought into contact. The sampling circuit outputs a power-on instruction signal to make the CPU perform the power-on operation. The sampling circuit stops its sampling operation once power is turned on.

摘要： The disclosed is an input and liquid crystal display unit including a flat liquid crystal display unit allowing input of data by manual writing having a plurality of partial display areas which are divisible into multiple units. The display unit overlays a magnetic tablet for inputting the designated data into the unit for display on the partial display areas. The display is driven to only some of said partial display areas to display the input pattern in the information on the partial display areas by applying a high duty cycle scan voltage to the common electrodes of the partial display areas.

摘要： A portable terminal device which can transfer data stored in a RAM to an external device even when any fault occurs in a key input portion or any abnormality occurs in part of the data stored in the RAM is provided. The CPU of the device controls a detection process to detect the state of a prescribed portion of the device and also controls a determination process to determine whether or not the data is to be transferred to the external device based on the detected result. When the CPU determines to transfer the data to the external device, the CPU controls the execution of a read process to read out the data stored in the RAM and a transfer process to transfer the data via a communication port thereof to the external device such as another portable terminal device.
