摘要： PROBLEM TO BE SOLVED: To improve the reliability between a microcomputer and a device by detecting whether or not serial data transferred from a CPU has an error and transmitting only error-free data to the device. SOLUTION: An error detecting circuit 10 detects whether or not the serial data transferred from the CPU has an error and transmits only error-free data to the device. A command analysis block 11 of the error detecting circuit 10 decides whether serial data sent out of the microcomputer 20 is normal data or a data clear command. A comparator 13 compares data in fetch buffers 11a to 11c and a resending request block 14 sends a request to resend serial data to the microcomputer 20 when the compared data are discrepant. An STB decision block 12 decides which device the serial data are communicated to. A clock generating circuit 15 generates a clock needed for serial communication to be set to a device.

摘要： PROBLEM TO BE SOLVED: To allow the ON/OFF of a power supply for a peripheral equipment using a software switch for a main power supply switch to interlock with the ON/OFF of a power supply for a computer body. SOLUTION: A CPU 3 stores the end state of each software switch in an EEPROM 4 at the time of its end. When voltage of +5V is supplied from a power supply circuit 2 by external factors F1, F2 for fixed time (time required from the start of the CPU 3 up to the processing of an ON/OFF control signal), the CPU 3 is started. After starting the CPU 3, the ON/OFF signal is immediately turned on and the circuit 2 is allowed to always supply power to the CPU 3. The CPU 3 refers to preceding end status data stored in the EEPROM 4 and controls the power supply of respective devices in accordance with the state of the end status data.

摘要： PROBLEM TO BE SOLVED: To simplify operation, to reduce the size of an input device and to save the space of a system by making it possible to operate three kinds of control, i.e., the input of absolute coordinates, the input of relative coordinates and the control of a cursor, by the use of a tablet alone. SOLUTION: A function switching button discriminating part 5 discriminates whether an input part function switching button 2 is depressed or not and inputs coordinates inputted from a tablet input part 1 to any one of a relative coordinate processing part 6, an absolute coordinate processing part 7 and a cursor control processing part 8. After the end of coordinate input processing from the selected processing part 6, 7 or 8, the current position of a mouse cursor on a display is stored. The processed coordinates are converted into an electric signal, which is outputted to an external device 12.

摘要： PROBLEM TO BE SOLVED: To immediately shift to an item to be adjusted in adjusting the various processings of a picture display device incorporated with an on-screen function on a screen. SOLUTION: This rotary switch device with pressure sensitive switch 1 is used as an adjusting input device. The adjusting item is allocated to the rotary position of the rotary switch on a one-to-one basis. An OR circuit 6 detects whether pressure sensitive output A is generated in a pressure sensitive switch detection part 2 or an information acquiring signal B from outside is detected in an information acquiring signal detection part 3. At that point, the position detection outputs (4 and 5) of the rotary switch are fetched in an AND circuit 7 and they are led out from a rotary switch output part with pressure sensitive switch 8 as information output C. Since the information output C corresponds to the adjusting item on a one-to-one basis, the adjusting item at that time can be displayed on the screen.
