It is intended to provide a tape printer which enables to forcibly separate a platen roller and a print head along with an opening movement of a cover element in case the platen roller and the print head have adhered to each other because of a long-period storage of the tape printer with the platen roller and the print head being in contact. Accordingly, a cam pressing member and a cam receiver move a roller holder to a withdrawing position in which the platen roller and a thermal head are separated from each other when the cover element is opened, so that the cam pressing member and the cam receiver can be forcibly returned to the withdrawing position from a position in which the platen roller is in contact with the thermal head.

A tape cassette includes an ink ribbon provided with a base film coated with an ink layer thereon and a film tape provided with a transparent film with an adhesive layer formed on one surface thereof. When an adhesive layer of the film tape and the ink layer of the ink ribbon of the tape cassette into contact at a print position, the ink layer is adhered onto the adhesive layer on condition that the adhesive layer is heated to exhibit self-adhesive properties, and characters and the like are printed on the film tape. At a tape printing apparatus with the tape cassette mounted thereon, by arranging a cutter unit immediately downstream the thermal head, a post-printing tape is cut promptly after printing.

A size-reduced printer that conveys a recording sheet in a circulating manner along a ring-like conveyance path while printing a plurality of images on the recording sheet in different colors sequentially in a superimposed manner, thereby forming a full color image. When a ribbon cassette that contains a multi-color ink ribbon is loaded at a predetermined position within a printer housing, a ring-like conveyance path is formed between the ribbon cassette and the printer housing. While the thermal head is driven and the recording sheet is conveyed once in a circulating manner along the conveyance path, a one-color image is printed on a previous printed one-color image in a superimposed manner in a corresponding one of the different color inks of the multi-color ink ribbon, thereby forming a full color image fully.

The mechanical isolation assembly is configured to compensate for variations in the planar orientation of the device under test. Moreover, the mechanical isolation assembly preferably includes bellows through which the refrigerant fluid is conducted.

A conventional thermal printer has had a structure in which a platen roller cannot be removed from a frame. Therefore, it has been necessary to insert a printing paper between a thermal head and the platen roller. Thus, it has been hard to load the printing paper. In order to solve the problem, there has been devised means for engaging the platen roller with the frame by the biasing force of the thermal head pressing the platen roller to forcibly lift up the platen roller, thereby removing the platen roller. However, there have been problems in that great operating force is required for the removal and the precision in a platen roller support position is low. A frame is provided with a slit (1c) having such a shape as to guide a bearing of a platen roller (2), and the bearing of a platen roller (2) is pushed against the slit by a lock arm using the biasing force of a pressure spring (8) for causing a thermal head (5) to come in press-contact with the platen roller (2). Consequently, the platen roller (2) is supported.

A disk drive has a resistive heater located near the read/write head as a thermal fly-height actuator and uses an improved method for operating the fly-height actuator. As part of the method, the heater may be deactivated during a seek to minimize the risk of head-disk contacts. When a write command is received, a level of heater power is applied to pre-heat the write head prior to writing the initial data sectors. This pre-heating heater power level may be higher than the power level used for writing. Then when writing commences, the lower power level is applied to the heater so the write head has the optimal head-disk spacing during the writing of all the data sectors, including the initial data sectors. Even though the heater may be deactivated during the seek the controller can initiate pre-heating during the last portion of the seek before the write head has reached the target track.
