An arm (10c) of a manual lever (10) is formed with a pushing portion (10f). A ratchet pawl (17) making reciprocal movement in synchronization with the manual lever (10) is formed with a resilient portion (17a) to be pushed by the pushing portion (10f) and a pawl portion (17b) which makes contact with a tooth of the ratchet wheel (19). A printer (P) is disposed at tip ends of the arms (10c, 10d). The ratchet wheel (19) is integral with the transfer drum (18). In the step of gripping the manual lever (10), the resilient portion (17a) is made to deform, and the pawl portion (27b) makes slide movement toward a tip end of a tooth. At the moment when the pawl portion (17b) gets over the tip end of a tooth, a resistive force against the manual lever (10) is significantly reduced, and as a result, the printer (P) makes impact contact with a label and prints marks on the label. When the label tape (12) is to set, the bottom cover (14) is made open. The bottom cover (14) can be surely open due to a biasing force accumulated in resilient portions (15d, 15e) by pressing a finger-placed portion (15a) of an engagement member (15). <IMAGE> |
