  • Patent number: 9296232
    Abstract: A thermal printer has a casing that houses recording paper, a printer cover connected to the casing in a manner turnable with respect to the casing around a first turning shaft for opening/closing the casing, a head unit provided on the casing and including a thermal head, and a platen unit including a platen roller and being provided on the printer cover and connected to the head unit in a manner releasable along with an opening/closing operation of the printer cover. The platen unit is mounted on the printer cover in a manner turnable around a second turning shaft that is parallel to the first turning shaft and slidable along a direction perpendicular to the second turning shaft. A biasing member is provided between the printer cover and the platen unit for biasing the platen unit toward the closing direction of the printer cover around the second turning shaft.
