Abstract: A cordinate input device is provided in which z-coordinate of an image object and a command to scroll the image can be inputted, a positive manipulation feeling can be obtained when changing scrolling speed (the amount of scrolling) of an image, and an accurate scrolling adjustment is enabled. The coordinate input device includes a casing, an (x, y) coordinate information input unit 6, push-button switches 7 and 8 for inputting the (x, y) coordinate information detected by the (x, y) coordinate information input unit 6, and an input manipulation unit for inputting z-coordinate information and image scrolling information in addition to the (x, y) coordinate information. The input manipulation unit includes a jog/shuttle switch 9 having a jog dial and a shuttle dial coaxially disposed.

Abstract: The electrical equipment of the present invention is operated such that the ON operating member for the primary power supply supplying circuit is manually operated, the switch device S is turned ON and when a supplying of electrical power for the primary power supply supplying circuit is shut off, the circuit for the control system is operated and upon performing a predetermined security processing, the driving source is driven, the OFF operating member is automatically operated, the switch device S is automatically turned OFF and supplying of an electrical power to the primary power supply supplying circuit is automatically shut off, so that it is possible to perform an appropriate processing before shutting off the primary power supply supplying circuit and thus it is also possible to provide electrical equipment showing a high safety characteristic.

Abstract: An electronic device having an auto-OFF function is disclosed in which a switch unit having an auto-OFF function and capable of being operated manually and automatically is connected to a primary circuit in a power control circuit, the switch unit S1 being normally turned auto-OFF with a signal provided from a control system circuit to cut off the supply of electric power to the primary circuit, thereby permitting a stand-by electric power to be nil, and if a trouble should occur in the control system circuit to an inoperable extent of the switch, the switch can be turned OFF manually.

Abstract: In the electric apparatus of the present invention, when the supply of electric power to a primary power supply circuit is started, a check is made to see if the apparatus has been turned ON by operation of a switch device S, by collation with the contents stored in a memory (not shown), and in accordance with the result of the collation a control system circuit makes control to continue or interrupt the supply of electric power to the primary power supply circuit. Therefore, in the case of a rise from an abnormal condition such as power failure, the supply of electric power to the primary power supply circuit can be interrupted rapidly. Thus, whether a trouble has occurred or not during power failure can be checked before resuming the operation and the occurrence of a danger can be prevented thereby.
