    • In a counter reset to zero by a push button and adapted to be mounted on a tape recorder or the like, there are provided a U shaped frame including a bottom plate, a pair of side plates, a spacer parallel with the side plates, a plurality of pinion aligning resilient members secured to the bottom plate, a digit wheel shaft supported by the side plates, a plurality of digit wheels rotatably mounted on the digit wheel shaft, and a driving gear rotatably mounted on the digit wheel shaft for driving a digit wheel of the lower most order. Each digit wheel comprises a heart shaped cam and a gear on one side and a carry pin gear on the other side. A zero resetting bracket is pivotally mounted on the frame and is provided with actuating members for actuating the heart shaped cams. The digit wheels are rotated by the source of drive of the tape recorder through the driving gear and each time a digit wheel of the lower order completes one revolution, a digit wheel of the higher order is rotated by one digit. A push button is mounted on either one of the side plates for simultaneously resetting to zero all digit wheels. In a modification a contact mechanism is provided for producing an electric signal which stops the operation of the tape recorder when the display of a digit wheel of the highest order changes from 9 to 0.
    • 在通过按钮重置为零并且适于安装在磁带录音机等上的计数器中,设置有U形框架,其包括底板,一对侧板,与侧板平行的间隔件, 固定到底板的多个小齿轮对准弹性构件,由侧板支撑的数字轮轴,可旋转地安装在数字轮轴上的多个数字轮以及可旋转地安装在数字轮轴上用于驱动数字的驱动齿轮 最低级的轮子。 每个数字轮包括心形凸轮和一侧的齿轮和另一侧的进给销齿轮。 零重置支架枢转地安装在框架上并且设置有用于致动心形凸轮的致动构件。 数字轮由磁带录音机的驱动源通过驱动齿轮旋转,并且每次较低级的数字轮完成一转时,高阶的数字轮转动一位数字。 一个按钮安装在任一个侧板上,用于同时复位到零数字轮。 在修改中,提供了一种接触机构,用于产生当最高阶的数字轮的显示从9变为0时停止磁带录音机的操作的电信号。

    • An internal pinion revolution counter includes a rotatable input shaft having first and second axial sections, and a bearing sleeve member rotatably supporting the first shaft section. A gear member is rotatably mounted on the sleeve member and has first and second axial sections, the first section having a first full tooth spur gear formed thereon. A first number wheel is secured to the second shaft section for rotation therewith, and an internal pinion transfer mechanism couples the first number wheel to the first spur gear. A second number wheel has a web portion joined to a hub portion mounted on the first spur gear for rotation therewith, and the second section of the gear member has a spur gear segment formed thereon as an extension of the first spur gear. A locking ring has a hub portion mounted on the second section of the gear member, and having an axial slot formed therein with the gear segment extending therethrough, the hub portion of the locking ring having an annular outer locking cam surface. The locking ring has an annular flange portion extending radially outwardly from the hub portion, the flange portion being secured to the web portion of the second number wheel. The gear segment has a portion extending axially beyond the hub portion of the locking ring. A pinion carrier disc is mounted on the sleeve member and has a transfer pinion rotatably mounted thereon, the transfer pinion having first and second axial sections. The first pinion section has a full tooth portion cooperating with the extension portion of the gear segment, and a mutilated portion cooperating with the locking cam surface. A third number wheel is rotatably mounted on the sleeve member and is driven by a second full tooth spur gear which cooperates with the second pinion section.
