    • The place shift-up mechanism of a digital clock comprises ratchet feed mechanism which permits manual setting of the clock even during the shift-up operation. The ratchet feed mechanism comprises an eccentric cam secured to a rotary shaft which also carries an eccentric operation pin. A ratchet wheel is rotatably supported by the shaft. A place shift-up lever is supported so as to be capable of rocking and sliding movement and has a forked leg plate with spaced legs receiving the eccentric cam between them. One leg of the forked leg plate has a feed pawl for engagement with the ratchet wheel and also a hook pawl engageable by the operation pin to move the place shift-up lever in one direction. The other leg of the forked leg plate has a return pawl which is engageable by the operation pin to move the plate shift-up lever in an opposite direction. The place shift-up lever is rocked by the eccentric cam and is moved by the operation pin first in one direction and then in the other to cause the feed pawl to engage the ratchet wheel to advance it one tooth for each revolution of the rotary shaft.
    • 数字时钟的位置移动机构包括棘爪进给机构,即使在升档操作期间也允许手动设置时钟。 棘轮进给机构包括固定到旋转轴的偏心凸轮,该偏心凸轮还承载偏心操作销。 棘轮由轴可旋转地支撑。 支撑地板移动杆,以便能够摇摆和滑动运动,并且具有叉形腿板,间隔开的腿接收它们之间的偏心凸轮。 叉腿的一条腿具有用于与棘轮啮合的进给棘爪以及可由操作销接合的钩爪,以沿着一个方向移动该位置升档杆。 叉形腿板的另一条腿具有可由操作销接合的返回棘爪,以沿相反方向移动板移动杆。 位置移动杆被偏心凸轮摆动,并通过操作销在一个方向上移动,然后另一方向移动,使得进给棘爪与棘轮啮合,使其旋转轴每转一个齿 。

    • An operation member slidably supported on a base plate has opposed pawls which are spaced apart and project toward one another. A position control cam and an integral supplementary cam are rotatably supported on the base between the two pawls. The pawls are disposed on different planes so that a first pawl is engageable with the control cam and the second pawl is engageable with the supplementary cam. The operation member is spring biased in a direction to move the first pawl toward the position control cam. The position control cam is provided alternately with deep concaves and shallow concaves. When the first pawl of the operation member engages in a deep concave it is in one position. When it engages a shallow concave it is in a second position. The supplementary cam has teeth at positions corresponding to the concaves of the position control cam. When the operation member is slidably moved in a direction opposite to the spring bias, the second pawl engages a tooth of the supplementary cam so as to rotate the supplementary cam and the position control cam to a new position. For example starting with the first pawl in a deep concave, sliding the operation member against the bias spring causes the second pawl to engage a tooth of the supplementary cam and thereby rotate the cams so that when the operation member is released the first pawl engages in a shallow concave of the position control cam and the operation member is thus in a different position.
    • 可滑动地支撑在基板上的操作构件具有彼此间隔开并且彼此突出的相对的棘爪。 位置控制凸轮和一体式附加凸轮可旋转地支撑在两爪之间的底座上。 棘爪设置在不同的平面上,使得第一棘爪可与控制凸轮接合,并且第二棘爪可与辅助凸轮啮合。 操作构件沿朝向位置控制凸轮移动第一棘爪的方向被弹簧偏压。 位置控制凸轮交替设置有深凹陷和浅凹陷。 当操作构件的第一棘爪啮合深凹时,它处于一个位置。 当它接合浅凹时,它处于第二位置。 辅助凸轮在与位置控制凸轮的凹部对应的位置处具有齿。 当操作构件在与弹簧偏压方向相反的方向上可滑动地移动时,第二棘爪与辅助凸轮的齿接合,以将辅助凸轮和位置控制凸轮转动到新的位置。 例如从第一棘爪开始在深凹部中,使操作构件抵靠偏置弹簧滑动,使得第二棘爪接合辅助凸轮的齿并由此旋转凸轮,使得当操作构件被释放时,第一棘爪接合 因此,位置控制凸轮和操作构件的浅凹部处于不同的位置。
