## Abstract

A motor-driven cam disk having a radially projecting, eccentrically arranged crank pin which generates a first movement, for example the pumping movement of a bellows pump. A running wheel which is pressed by a spring force against the cam disk in a resilient manner is arranged in the radial direction on the cam disk. The running wheel serves to generate a second movement, for example the swiveling movement of a swivel lever. For this purpose, the motor-driven cam disk has two cam paths which are offset relative to one another in a stepped manner and pass into one another at two locations on the cam disk. The cam disk has a switch tongue to enable the movements generated by the motor-driven cam disk to be decoupled from one another.

## Claims

### Claim 1

A device for generating and decoupling different movements in cleaning and sealing stations in ink printers, comprising:
a motor-driven cam disk having two directions of rotation and a projecting, eccentrically arranged crank pin for generating a first movement,
the motor-driven cam disk further having first and second cam paths which are offset relative to one another in a stepped manner and merge into one another at two locations on the cam disk;
a running wheel guided by the cam paths and arranged in a resilient manner on the cam disk by a spring force for generating a second movement in a radial direction relative to the cam disk; and
a switch tongue arranged on the cam disk so as to decouple the second movement from the first movement in one of the directions of rotation of the cam disk by controlling a rotating path of the running wheel around the cam disk as a function of the rotating direction of the motor-driven cam disk.

### Claim 2 (depends on 1)

A device according to claim 1, wherein the switch tongue is a self-controlling switching tongue.

### Claim 3 (depends on 1)

A device according to claim 1, wherein the switch tongue is arranged between the two locations on the cam disk where the first cam path merges into the second cam path.

### Claim 4 (depends on 1)

A device according to claim 1, wherein the cam disk has a rim, the switch tongue having one end fastened to the cam disk at one of the two locations where the first cam path merges into the second cam path and an opposite end that abuts the rim of the cam disk in a resilient manner so as to brush over the two cam paths.

### Claim 5 (depends on 1)

A device according to claim 1, and further comprising spring means imparting an axial spring force against the running wheel so that rotation of the cam disk causes the running wheel to act against the axial spring force.

### Claim 6 (depends on 1, 5)

A device according to claim 1 or 5, wherein the running wheel is provided so as to alternately rest on the first cam path under the influence of the switch tongue and lift from the second cam path to form an air gap from the second cam path.

### Claim 7 (depends on 1, 5)

A device according to claim 1 or 5, wherein the running wheel is lifted from the second cam path to form an air gap from the cam path when the second movement is decoupled from the first movement.
