    • A friction drive device transmits torque by frictional contact between rollers. The friction drive device includes a casing, a drive roller that is supported for relative rotation with respect to the casing, a driven roller that is supported for relative rotation with respect to the casing, a cam mechanism that presses the drive roller and the driven roller into contact with each other, and a damper. The cam mechanism includes a surface that is disposed at an angle with respect to a tangent of the contact between the drive roller and the driven roller, and includes a rotational support part that is disposed on the surface and supports one of the drive roller and the driven roller such that displacement along the surface by the rotational support part maintains the frictional contact for transmitting the torque. The damper reducing vibration of the rotational support part.

    • A friction drive device includes a first roller with a support part, a second roller, and a cam member to support them. The second roller receives press force from the first roller at a contact point of them so as to transmit mechanical power therebetween. The cam member has a cam formed with a cam slope on which the support part of the first roller is pressed by reaction torque from the second roller that is caused by transmission torque applied from the first roller. The cam slope is formed to have an angle with respect a tangent line at the contact point so that the first roller is pressed by reaction force of the cam to apply the press force proportional to the transmission torque to the second roller.
    • 摩擦驱动装置包括具有支撑部分的第一辊,第二辊和用于支撑它们的凸轮构件。 第二辊在它们的接触点处接收来自第一辊的压力,以便在它们之间传递机械动力。 凸轮构件具有形成有凸轮斜面的凸轮,第一辊的支撑部分由第二辊由来自第一辊施加的传递扭矩引起的反作用力推压在该凸轮上。 凸轮斜面形成为在接触点处具有与切线相对应的角度,使得第一辊被凸轮的反作用力按压,以将与传动扭矩成比例的压力施加到第二辊。

    • In a position measuring device in which data, which requires buffering, may be held without accommodating a high-capacitance capacitor in the inside of the encoder, a backup current source may be exchanged while the circuits required for the operating capability state remain operable. In addition, current usage during the buffering time may be held low, and the service life of the backup current source may be extended, so that the demand for maintenance may be reduced. The position measuring device may include an encoder main part, arranged to measure the extent of the shift in position of an object to be measured, and a backup current source arranged to supply backup current when main current source, that supplies encoder main part with current, is interrupted. Outside of the encoder main part, an auxiliary current source is provided which, during the exchange of a main battery of the backup current source, undertakes supplying backup current in place of this main battery. The backup current source supplies backup current only to those circuits of the encoder main part which require buffering.

    • A driving device includes a drive source, a driving unit, and a driven member. The drive source is configured and arranged to generate a driving force. The driving unit is coupled to the drive source to move with a reciprocating motion between first and second directions by the driving force. The driven member is arranged to frictionally engage with the driving unit to move in the first direction in response to the reciprocating motion of the driving unit. The driving unit is further arranged to convert a portion of the driving force into a pressing force that acts on the driven member in a direction substantially perpendicular to the first and second directions with a first conversion ratio when the driving unit moves in the first direction and with a second conversion ratio smaller than the first conversion ratio when the driving unit moves in the second direction.
