    • A time recorder includes a clock circuit for producing a clock signal, a detector for detecting when a time card is loaded in the time recorder to produce a detection signal, and a correcting circuit for producing a correcting signal effective to correct time information. A printing wheel assembly is rotationally driven to print the time information which is displayed in a display device. A positioning mechanism receives the loaded time card and moves relative to the printing wheel assembly for positioning the loaded time card in a print position relative to the printing wheel assembly. A hammer is opposed to the loaded time card and actuated to act thereon against the printing wheel assembly to thereby print the time information. The display device, printing wheel assembly and positioning mechanism are driven in synchronization with one another to update and correct the displayed time information, the time information to be printed and the position of the time card in response to the clock and correcting signals. The hammer is actuated in response to the detection signal without relative interference with the drive of the printing wheel assembly and positioning mechanism.
    • 时间记录器包括用于产生时钟信号的时钟电路,用于检测时间卡何时加载到时间记录器中以产生检测信号的检测器,以及用于产生有效校正时间信息的校正信号的校正电路。 旋转地驱动印刷轮组件以打印在显示装置中显示的时间信息。 定位机构接收加载的时间卡并相对于印刷轮组件移动,用于将加载的时间卡相对于印刷轮组件定位在打印位置。 锤子与装载的时间卡相对,并被致动以在打印轮组件上作用于其上,从而打印时间信息。 显示装置,印刷轮组件和定位机构彼此同步地被驱动,以响应于时钟和校正信号来更新和校正所显示的时间信息,要打印的时间信息和时间卡的位置。 锤子响应于检测信号被致动,而不会相对于印刷轮组件和定位机构的驱动而受到干扰。

    • A time recorder is normally powered by a main power source for supplying a commercial power and occasionally powered by a back-up power source during interruption of the commercial power supply. A clock means counts time to constantly produce a clock pulse, and a digital display constantly digitally indicates updated time data in response to the clock pulse. An analogue display is driven for analogically indicating time information and a recording mechanism is driven for recording time information on a recording medium. A driving device drives the analog display and recording mechanism in response to the clock pulse to update the time information indicated in the analog display and recorded by the recording mechanism. A detecting device is connected to the main power source for detecting the interruption of the commercial power supply. A controlling device responsive to the detection of the commercial power supply interruption inhibits the operation of the driving device during the commercial power supply interruption so that the driving device suspends the driving of the analog display and recording mechanism to thereby cause a delay of the time information from the updated time data, and operates after recovery of the commercial power supply for controlling the driving device to quickly drive the analog display and recording mechanism to correct for the delay to thereby update the time information.
    • 时间记录器通常由用于提供商业电力的主电源供电,并且偶尔由商业电源中断期间的备用电源供电。 时钟装置计算不断产生时钟脉冲的时间,并且数字显示器不断数字地指示响应于时钟脉冲的更新的时间数据。 驱动模拟显示器用于模拟地指示时间信息,并且驱动记录机构以在记录介质上记录时间信息。 驱动装置响应于时钟脉冲驱动模拟显示和记录机构,以更新模拟显示器中指示的并由记录机构记录的时间信息。 检测装置连接到主电源,用于检测商用电源的中断。 响应于商业电源中断的检测的控制装置在商用电源中断期间禁止驱动装置的操作,使得驱动装置暂停模拟显示和记录机构的驱动,从而导致时间信息的延迟 并且在恢复用于控制驱动装置的商用电源之后操作,以快速驱动模拟显示和记录机构来校正延迟,从而更新时间信息。

    • A camera shutter having a shutter aperture, shutter blades, and a driving device for driving the shutter blades to open and close the shutter aperture. The driving device includes a pair of lever members spaced apart and confronting each other across the shutter aperture, each of the lever members having a first end portion and a second end portion. A piezoelectric element is connected to and between the lever members at the first end portions thereof for undergoing elastic deformation to oscillate the lever members. An elastic member is connected to and between the lever members at the second end portions thereof for undergoing elastic displacement in response to oscillation of the lever members. A transmission member is integrally connected to a central portion of the elastic member for transmitting the displacement of the elastic member to the shutter blades to open and close the shutter aperture.
