<p>PURPOSE:To improve operability by protruding and housing a pawl member while being interlocked with the operation of attaching or detaching the member from the main body of an operation input device. CONSTITUTION:When a projecting part 1b of a cae 1 is fit into a hole 10b and a keyboard is turned in a clockwise direction, a button 4 is pushed down by an enclosure 10 and a lever 7 pushes a pawl 6 up so that the pawl can be protruded at the external part and put into an opening part 10a. While being turned against the energizing force of a spring 8, the pawl 6 is raised and the upper end part is engaged to the opening part 10a. When detaching the main body of the keyboard, a knob 5 is slid backward and the engagement of the pawl 6 is released. Then, the keyboard is turned in a counterclockwise direction and the pawl 6 is pulled out from the opening part 10a. Afterwards, when the projecting part 1b is pulled out from the hole 10b and detached from the enclosure 10, the button 4 is pushed up by the energizing force of a spring 9 and the lever 7 is turned in the counterclockwise direction. Then, the pawl 6 is housed in the enclosure. Thus, the operability can be improved.</p> |
