<p>PURPOSE:To quickly establish an optimum operation posture by providing an interlocking mechanism being capable of changing automatically the direction of a CRT part by interlocking with the movement of a keyboard part. CONSTITUTION:When a keyboard part 1 formed as one body with T type parts 11 is rotated and moved to the right and left, a projection 11a of the T type parts 11 transmits a movement of the keyboard part 1 to I type parts 12, while sliding in a groove 12a of the I type parts 12. The I type parts 12 to which the movement has been transmitted by the T type parts 11 are formed as one body with a CRT part 3, therefore, a movement of a horizontal swing of the I type parts 12 is transmitted as a rotational movement to the CRT part 3, and the CRT part 3 rotates to match a movement of the keyboard part 1. Also, a variation of a distance between a revolving shaft of the CRT part and the keyboard part 1, generated due to a fact that the revolving shaft 3a of the CRT part 3 at the time and the center of a circular arc used for a shape of the keyboard part are different can be executed due to a fact that the projection 11a of the T type parts 11 slides in the groove 12a of the I type parts 12. In such a way, a quick and optimum operation posture can be established.</p> |
