According to one embodiment, a current detection circuit () includes: a detection resistor (Rs) provided between a solenoid valve () and a solenoid driver (); an amplification unit () configured to amplify a detected voltage of the detection resistor (Rs); an AD converter () that is driven by a reference voltage (Vref) generated based on a reference current (Iref) and configured to convert an output voltage from the amplification unit () into a digital value and output the digital value as a detected current value (D); and a correction unit configured to perform a correction on the detected current value (D). The correction unit includes: a temperature sensor (); a storage unit () configured to store information about temperature characteristics of the detected current value (D) generated due to temperature characteristics of a reference current in each of two or more different temperature regions; and an operation unit configured to apply, to the detected current value (D), a first correction coefficient calculated based on a detection result of the temperature sensor () and information about temperature characteristics of the detected current value (D) stored in the storage unit ().

An ink roller cover device of a portable type label printing applicator so that the ink does not dry-up easily in stored or standby state by closed storage of the ink roller. An ink roller is stored in a cover including a fixed cover part which can cover and store a part of a roller body in a standby state of the ink roller and a complementary movable cover part which covers and stores the other parts of the roller body when the cover parts are closed in a standby state of the ink roller. The movable cover part is capable of exposing the roller body towards a printing device in an operating state of the ink roller. An operating lever moves the ink roller with the movable cover part away from the fixed cover part.
