Abstract

PURPOSE:To prevent a signal cable from being the obstacle of an X cursor and a balance weight and to prevent the signal cable from being influenced by abrasion, damage, or dust in a designing and an actual traveling by making a thin band-shaped flat cable guidable smoothly along a Y rail without bending the flat cable in the middle of its guiding. CONSTITUTION:Since flat cable 40 has resiliency and can be bent freely flexibly,the flat cable 40 is fixed through a bending part 40a on a pressing stand 37 by a pressing plate 38 and housed in a T groove 39 provided along the side wall of a Y rail 4 in a vertically rising state along the vertical groove of the T groove 39 by adhering a T-shaped guiding plate 41 and a vertical guiding plate 42 to the flat cable 40 from both sides of the flat cable 40. The guiding plates 41 and 42 not only maintain the bent state of the flat cable 40 but also prevent the frictional contact of the T groove 39 and the flat cable 40, prevent the damage of the flat cable 40, protect the flat cable 40, and hold the smooth moving of the flat cable 40 in the T groove 39. Thus, the signal cable never becomes the obstacle of the X cursor and the balance weight in the designing and the actual traveling, and the signal cable is never influenced by the abrasion, the damage, or the dust.

It is configured so that it can be displayed digitally on a display section 14 provided.

Therefore, the arrangement of signal cables for power supply and information processing between the X cursors becomes a problem.

In other words, the signal cable that connects one end to the X cursor and the other end to the X cursor must be connected while expanding and contracting as the X cursor moves along the Y rail. It may be out of the question to store it outside the Y-rail as it will interfere with drafting work, etc., but even if it is stored inside the Y-rail, for example, it will still be inside the roller running path of the X cursor or the roller running path of the balance weight. There is a problem that it becomes a hindrance to driving and is affected by wear, damage, dirt, etc.

Therefore, the present invention provides a signal cable storage device for an XY digital display drafting machine, etc., in which the signal cable 40 is stored in a T groove provided in a Y rail, and the connection relationship is maintained by following the circular layer as the Y cursor moves.
