A punch device for coding cards, tapes and the like comprises a pivotably mounted spring biased punch lever, and a punch member for punching a code into a program card or the like movably mounted on one end of the punch lever. An oscillatable yoke is connected to the punch lever through a hammer lever. A rotating eccentric drive rotatably mounted in the yoke continuously oscillates the yoke. An electromagnetically actuable pawl is reciprocably movable against a spring biased trigger lever for pivoting the trigger lever into a position between an end of the hammer lever and the end of the punch lever in which the punch member is movably mounted. When the trigger lever is moved by the pawl between the hammer lever and punch lever, the oscillation of the yoke by the eccentric drive upwardly moves the punch member into a punch position. As the pawl releases the trigger lever, the bias on the trigger lever moves the trigger lever from its position between the hammer lever and punch lever whereby the oscillation of the yoke has no significant effect on the punch member.
A punch device for coding cards, tapes and the like comprising a punch lever pivotably mounted to be coordinately pivotably displaceable between a first and second position, a punch member coupled to a first end of said punch lever to be displaced thereby, an oscillatable yoke, a hammer lever pivotably mounted to said yoke, said hammer lever being pivotably displaceable in the same pivotable orientation as said punch lever, drive means for oscillating said yoke and hammer lever mounted thereto, a trigger lever coordinately displaceable between a first position offset respectively and mechanically distinct from said hammer lever and said punch lever and a second position between said hammer lever and said punch lever for displacing said punch lever from said first position to said second position in response to said oscillation of said yoke, said punch lever and said hammer lever being pivotably displaced in the same pivotable direction when said trigger lever is disposed in said second position by the displacement of said punch lever from said first to said second position.
