Abstract: A processor with real-time signal transmission and storage comprises a motherboard and a display. The motherboard has a power input end, a processing core, a signal input end, a storage device and an image output end. The power input end has one conducting wire to connect to the power source to provide power to the motherboard and a display; the processing core has a processing program inside and connect to the signal input end and the storage device; the signal input end provides a transmission line to connect an input end of a working unit; and the storage device provides space to save signals complied and organized by the processing core. The display has a signal connector to connect to the image output end of the motherboard.

Abstract: A keyboard includes a control panel and a cursor controller. The cursor controller includes a first key unit provided on the control panel, a second key unit provided on the control panel and a photo-sensor unit provided on the control panel. When a user moves his finger over the photo-sensor unit, the photo-sensor unit senses the movement and causes a cursor to move on a screen of a display of a computer used with the keyboard.

Abstract: A camera power source control device comprises a press switch and a mechanical start switch. The press switch is disposed on one circuit located between the camera power source and a zoom cylinder control motor such that the circuit is connected at the time when the press switch is pressed, thereby driving the control motor to extract the zoom cylinder to locate at a predetermined position. The circuit is disconnected when the press switch is not pressed. The mechanical start switch is disposed on other circuit located between the camera power source and the zoom cylinder control motor and is formed of a first contact electric piece and a second contact electric piece, which are separated from each other at the time when the zoom cylinder is retracted to a closed position. The two contact electric pieces are in contact with each other at the time when the zoom cylinder is extracted to locate at a standby position.
