<p>PURPOSE:To use the number of switches of the operating part to the minimum, to miniaturize the operation system, and also, to improve the use convenience by detecting position data of a pressure key on a transparent touch keyboard, outputting mode data of an operating state of an apparatus and converting the position data of the pressure key to a control signal of the apparatus. CONSTITUTION:A detecting signal is outputted at every vertical line of a transparent touch keyboard 11, and by executing the detection of a signal at every horizontal line, a position of a pressure key is detected and position data is outputted. A mode control means 15 detects an operation mode from a VTR control signal and switches and outputs mode data of an operation key and a control signal converting means 14 switches and outputs a control signal at every inputted mode data. A display control means 17 also switches the contents of an operation symbol on a display part 16 at every inputted mode data. Accordingly, when the key of the transparent touch keyboard key 11 is operated, the display contents of the operation symbol are switched every time thereof, and only a necessary operation switch is displayed. In such a way, the operating panel is miniaturized, and the operability can be improved.</p> |
