摘要：
A print head pressure-contact device equipped with a linkage for applying a print head onto a platen of a printer, comprises a drive lever having a driven connection with a motor and a driven lever rotatably linked to the drive lever. The drive lever has a cam and the driven lever has a cam follower cooperative with the cam, such that a power transmission is changed from a linkage transmission to a cam transmission within a predetermined angle range with respect to an angle between the two levers.
