A housing including a base and cover has an open space that is open to the atmosphere and a closed space that is closed to the atmosphere. The open space contains a laser having a low operating temperature. The closed space contains a heat generating element and the like, which have higher operating temperatures than the laser. The heat generating element is in close contact with the base, which also serves as a heatsink, so that the heat generating element is cooled. Most parts of a motor, which is a heat generating member, are disposed in the closed space. A fan is diagonally disposed with respect to side surfaces of the heat generating element, which has a rectangular shape and flat side surfaces, so as to efficiently blow air toward the heat generating element disposed in the closed space.

A linear and curvilinear motor system includes: linear and curvilinear guiding devices movably guiding and respectively supporting right and left of a slider, each having a guide rail configured by linear tracks and a circular arc track and slider blocks; a motor unit having a stator with a stator linear section and a stator circular arc section and a mover with a linear section and provided for the slider and away from the stator with a gap interposed therebetween; and an encoder head and a hole sensor detecting positions of the linear tracks and the circular arc track. When a magnetic pole pitch of the linear section of the stator is a distance &#x3bb;m and a magnetic pole pitch of the circular arc section of the stator is an angle &#x3b3;m, a radius r of the circular arc track at the position detection point is defined as r=&#x3bb;m/&#x3b3;m.

A hand-held control device comprises a casing (,) having a plurality of operating switches (,) and a cut hole (,) in front face thereof, a transparent window (,) fitted in the cut hole (,) of the casing (,), a printed circuit board (,) accommodated in the casing (,) and connected to the operating switches (,), a crystal liquid display plate (,) disposed near the window (,) of the casing (,) and connected to the printed circuit board (,) through a connector (,), the crystal liquid display plate (,) being fixed with a mounting member (,) so as to the connector (,) is sandwiched between the mounting member (,) and the printed circuit board (,), and an upper cover (,) and a lower cover (,) for holding the printed circuit board (,) through the buffer member (,). Accordingly, even when an impact is applied onto the casing (,), the liquid crystal display plate (,) is less affected thereby, and therefore the contents of display can be surely displayed on the liquid crystal display plate (,).
