Abstract
Abstract In a cross-movable carriage comprising a movable base plate and a stationary base plate, the movable base plate has two first guide grooves formed in one surface thereof and the stationary base plate has two second guide grooves formed in one surface thereof. A guide mechanism comprises two first guide members capable of fitting in the first guide grooves and two second guide members capable of fitting in the second guide grooves. One of the second guide members and one of the first guide members are fastened together, and the other of the second guide members and the other of the first guide members are fastened together. The guide mechanism is provided between the movable base plate and the stationary base plate to permit the first guide members to fit in the first guide grooves and permit the second guide members to fit in the second guide grooves.
