CONSTITUTION:When an operation lever of a selection mechanism provided along the upper part of a foot pedal 15 is operated to be on an ascent drive position (a descent drive position) and the pressing operation of the foot pedal 15 is repeated, the operation is converted to one way rotating motion of a first drive shaft 27 through a first power transmission mechanism 38 (a second power transmission mechanism 39), a screw shaft 20 is rotated through a bevel gears 29 (30) and 21 so as to lift (lower) a nut 23, and a loading base 14 is lifted (lowered) by approaching the rotational motion (separating rotational motion) of the link pair of a pantograph mechanism. In this case, the positions of the swing axis of the foot pedal 15, namely the first and second drive shafts 27, 28 are not changed, and hence the foot operating position of the foot pedal 15 is always constant and good operability can be obtained, regardless of the elevatable motion of the loading base 14.

Filed: 1986-08-15
Abstract: PURPOSE:To enable equal constant currents to flow through output current switch circuits without correcting a resistance by limiting constant current source transistor connecting points of the switch circuits to a span adapted for specific conditions in a VEE power source bus. CONSTITUTION:It is determined that a span voltage drop due to a bus current flowing to the span becomes at least 0. 026 eta (volt) or lower with respect to maximum/minimum current ratio (1+eta) specified in constant current source transistor groups Q4-Q7 of output current switch circuit group as a position in the minimum potential power source but of the span for connecting the transistors Q4-Q7. That is, the span l is so determined as to satisfy the condition of the potential difference (V7-V4), where the potential of a VEE power source bus connecting point A7 is V7 and the potential of the connecting point A4 is V4. Thus, the current value of the output current switch circuit can be constant without particularly correcting the emitter resistance of a constant- current source transistor.
