Claims
- 1. In an in-and-out time recorder the combination comprising a printing device for printing clock times along the lines of a data medium; retaining means for holding the data medium adjacent the printing device; said printing device being slidably mounted for displacement substantially parallel to the lines of the data medium; said printing device comprising a plurality of adjacent number wheels provided with number print types for imprinting clock times onto the data medium; indexing means connected to said number wheels for indexing said number wheels; an electric motor for effecting displacement of the printing device relative to the retaining means; drive means coupling said electric motor to said printing device, and including a resilient coupling switch means for switching said electric motor on and off at the beginning and approximately at the end respectively of each displacement of said printing device, and positioning means positively coupled with the printing device in at least one direction of displacement of said printing device for positioning the same in predetermined positions relative to a line of the data medium.
- 2. A time recorder as claimed in claim 1, wherein said positioning means comprises a recessed positioning element positively coupled with the printing device in at least one direction of displacement; such recesses corresponding with said predetermined positions and being engaged by a ratchet element which is urged into engagement therein when the printing device reaches one of its predetermined positions.
- 3. In a time recorder as claimed in claim 1, wherein said resilient coupling drives the positioning element positively coupled with the printing device.
- 4. In a time recorder as claimed in claim 2, wherein said switch means for said motor is actuated by said ratchet element into the off position.
- 5. In a time recorder as claimed in claim 1, wherein said indexing means comprises a lever, and an indexing arm for actuating said lever is rotatably mounted on an indexing spindle and shiftable along said spindle axis between a first and a second position in which the indexing spindle and said lever are coupled and uncoupled, respectively.
- 6. In a time recorder as claimed in claim 5, wherein a disc cam indexed in steps by half the cam width and a cam follower are operatively connected to and shift said indexing spindle.
- 7. In a time recorder as claimed in claim 6, wherein the cam follower comprises a second lever pivotally mounted for movement about an axis extending transversely to the indexing spindle and engages a groove disposed in said indexing spindle.
- 8. In a time recorder as claimed in claim 5, wherein said indexing means comprises an indexing rod extending parallel to and is movable generally transversely to the sliding direction of the printing device, in response to a pivotal movement of said lever; and means on said printing device responsive to a movement of the indexing rod for indexing the number wheel.
- 9. In a time recorder as claimed in claim 1, with a rear wall carrying said retaining means and a stop abutment for the data medium, which stop abutment is slidable along the vertical axis of said retaining means; said rear wall being detachably held on said recorder.
- 10. In a time recorder as claimed in claim 9, wherein said rear wall is provided with a resilient support for the data medium during the printing operation; said support being arranged opposite the printing device.
- 11. In an in-and-out time recorder the combination comprising a printing device for printing clock times along the lines of a data medium; retaining means for holding the data medium adjacent the printing device; said printing device being slidably mounted for displacement substantially parallel to the lines of the data medium; said printing device comprising a plurality of adjacent number wheels provided with number print types for imprinting clock times onto the data medium; indexing means for indexing said number wheels; said indexing means comprising first and second movable supports extending generally parallel to the sliding direction of the printing device; a first indexing arm mounted on a first one of said supports for movement therewith; a second indexing arm mounted on a second one of said supports for movement with the second support; said second indexing arm being engageable with and movable by said first indexing arm; said second support being operatively connected to said number wheels for indexing the number wheels during movement of said second support, and means for altering the relative disposition between said indexing arm along an axis parallel to said supports between a first and a second position in which the first and second indexing arms are engaged and disengaged respectively.
- 12. The time recorder as claimed in claim 11, wherein the altering means comprise a disc cam and a cam follower which are operatively connected to and shift one of said indexing arms.
- 13. The time recorder as claimed in claim 12, wherein the cam follower comprises a second lever pivotally mounted for movement about an axis extending transversely to the shifting direction of said indexing arm to be shifted and engages a grooved element rotating with the indexing arm to be shifted.
- 14. In a time recorder as claimed in claim 11, with a rear wall carrying said retaining means and a stop abutment for the data medium, which stop abutment is slidable along the vertical axis of said retaining means; said rear wall being detachably held on said recorder.
- 15. In a time recorder as claimed in claim 14, wherein said rear wall is provided with a resilient support for the data medium during the printing operation; said support being arranged opposite the printing device.
