Abstract: A printer in which when an optical disk is inserted into a conveyance path in a printer body, an inlet cover is moved to a position where the inlet cover opens an inlet in a cover provided on the printer body. This causes a cutter button that operates a cutter for a tape-like printing medium to be locked by the inlet cover. Thus, when the optical disk is printed, the cutter is rendered inoperable. Accordingly, the printer can prevent a trouble such as inadvertently operates the cutter, thereby damaging the disk or the cutter itself.

Abstract: A driving waveform which an inkjet head filled with inspecting ink shows is measured. The measured driving waveform is corrected based on a correlation formula, which is obtained beforehand based on image recording ink the inkjet head uses for image recording. The inkjet head is set to have a driving waveform based on a result of correction.

Abstract: A printer for printing character information on an optical disk using an ink cartridge. The printer comprises a printer cover for opening/closing a cartridge receiving section into which the ink cartridge will be loaded. When the ink cartridge is loaded into the cartridge receiving section, the cover is closed and then the optical disk is inserted into the printer. Then, printing is started. The cover is engaged with the printer body in a closed state. The cover is disengaged by operating an operation button. When the optical disk is inserted into the printer body, an inlet cover is pushed by the optical disk so as to be upstanding. This causes a lock member to protrude so as to engage with the operation button, thereby locking the operation button and hence rendering the cover unopenable.

Abstract: When a thermal head prints on a print tape with a tape cassette retained in a receiving section of a main body, the print tape undergone printing is cut by a stationary blade and a movable blade of a cutting mechanism, and when the thermal head performs printing on an optical disk retained in the receiving section of the main body, the cutting section does not operate to the optical disk undergone printing.

Abstract: A main body has a receiving section, which contains an ink ribbon cassette holding an ink ribbon, together with an optical disk. The ink ribbon and the optical disk are fed by a platen roller, and printing is performed on the optical disk through a thermal head. The optical disk is inserted from an insertion port at a side of the main body parallel to the feed direction of the ink ribbon. When the optical disk is inserted from an ejection port in a direction orthogonal to the fed direction of the ink ribbon, an insertion-prevention member prevents the insertion of the optical disk.

Abstract: In a case (101) with the shorter side at the top, a tray (121) is placed substantially vertically, an optical disk (170) is substantially vertically supported on the tray (121), and a printer section (135) is provided to be opposite to the tray (121). In the printer section (135), a carriage (141) equipped with a thermal head (142) is structured to be movable vertically along the tray (121). When the carriage (141) moved vertically downward, the thermal head (142) is driven to provide thermal transfer printing of a title and the like, which indicate the contents of data recorded on the optical disk (170), to the surface thereof through an ink ribbon (162).

Abstract: This printing apparatus comprises a support tray provided with a rotatable base, and an optical disk as a printing object is mounted on the rotatable base. A control section of the printing apparatus selectively operates rotation drive means for driving the rotatable base to be rotated and print means for printing predetermined data on a surface of the optical disk, thereby executing printing to a plurality of portions of the optical disk.

Abstract: A driving waveform which an inkjet head filled with inspecting ink shows is measured. The measured driving waveform is corrected based on a correlation formula, which is obtained beforehand based on image recording ink the inkjet head uses for image recording. The inkjet head is set to have a driving waveform based on a result of correction.

Abstract: A thin ribbon cassette (16) is a set on a tape winding device and its vertical-direction position is fixed by a position restricting member (18) provided on a back of a cover and for an apparatus body. When the ribbon cassette (16) is thin in correspondence to a narrow width of an ink ribbon (15), a quantity of lowerig a ribbon winding top (5) engaged with a reel (16-1) of the cassette (16) is small. The biasing force of a clutch spring (7) which is compressed depending on the quantity of lowering of the ribbon winding top (5) is small, the force of a winding driver gear (6) which presses a clutch plate (4-1) through a felt member (12) is small, the frictional force of the felt member (12) is small, and the torque of the rotational shaft (4) is small. This torque is just suitable for winding a long and narrow ink ribbon having a corresponding small tensile strength.

Abstract: A tablet printing machine provided with a roll soiling detecting unit for optically detecting soiling of the surface of a roll of its printing unit. The machine is further provided with a roll cleaning unit including a cleaner to be impregnated with a cleaning liquid and adapted for pressing contact with the transfer roll of the printing unit during the rotation of the roll.
