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 .
