Abstract: In the developed state of the combiner 13, the first arm 19 extends along a vertical line passing the center of gravity G of the combiner 13, and the second arm 21 and the third arm 23 are aligned on and extended along a line which couples the rear end of the base member 17 and the other end 19b of the first arm 19 and tilts from the vertical direction toward the horizontal direction so that the combiner 13 is arranged in front of the eye point I at a tilting angle of reflecting the image light of the displayed image emitted from the display device of the projector unit 9 toward the eye point I of the driver 3. In such a configuration, the virtual image of the displayed image on the combiner which is to be visually recognized from the eye point can be visually recognized stable with no shaking in a vehicle which is susceptible to the vibration from the road face.

Abstract: A meter for a motor vehicle includes a meter case 4 for protecting components of the meter which are incorporated therein, and a front cover 9 composed of a prism which is a part of a convex lens and provided in front of the meter case 4. A dial plate 5 of the meter has an outer contour in a substantially elliptical shape so that a virtual image of the dial plate as seen through the front cover 9 may look like a substantially perfect circle. Since the virtual image of the dial plate 5 is expanded in a vertical direction due to magnification inherent in the prism 9, the dial plate 5 formed in a substantially elliptical shape will be deformed into a substantially perfect circle in sight.

Abstract: Every time the cumulative number of revolutions of a spindle rotating motor reaches a cumulative number of revolutions set in a data table, a CPU reads out, from a data memory section, moving positions of a workpiece and tool at the reached cumulative number of revolutions and the next cumulative number of revolutions, and a spindle rotational speed instruction value at the reached cumulative number of revolutions. The CPU sets the reached cumulative number of revolutions as a start point and the next cumulative number of revolutions as an end point, and divides the interval between the start and end points at predetermined timings. The CPU determines moving positions of the workpiece and tool at divided timings on the basis of the readout moving positions of the workpiece and tool. The CPU outputs the spindle rotational speed instruction value as a spindle rotational speed instruction signal to a reference spindle rotational speed setting circuit to control the rotational speed of the spindle rotating motor.

Each of the machining units includes a plurality of inflection points including a machining start point and a machining end point. Machining data at least necessary for performing machining is set for each of the machining units. Arrival times at the inflection points are calculated based on the machining data, and a position of at least one of the workpiece and the tool is calculated for each of the inflection points. For each of the machining units, a rotation angle position of the workpiece corresponding to the arrival time is set as an accumulated count value.
