Embodiment Construction

[0026] Refer to the following Figure 1 to Figure 9 A first embodiment of the belt conveyor of the present invention will be described.

[0027] refer to figure 1 Describes the outline of a printer using a thermal transfer film tape.

[0028] The printer 1 is composed of a main body unit 2 , a tape conveyor 3 and a head unit 4 . The belt conveyor 3 is placed on the main body unit 2 . The tape conveying device 3 can be lifted from the main body unit 2 when replacing or inspecting the ink ribbon. A paper roller 6 and a paper platen 7 are installed on the cabinet 5 of the main unit 2 . The platen 7 is driven to rotate by a motor (not shown) for rotating the platen. The upper surface of the cabinet 5 constitutes a paper conveying path, and the paper 8 drawn from the paper cylinder 6 moves toward the paper conveying path through the rotation of the platen 7. figure 1 sent in the left direction. Moreover, in this embodiment, the paper 8 is a label paper with a width of about ...

Abstract

The invention relates to a ribbon feeder of printer. Ribbon tension detecting means (20, 21) each consisting of a plate-like lever body (35) are disposed upstream and downstream, respectively, of a ribbon path from a platen (7). The plate-like lever body (35) has first and second rollers (47, 48) disposed upstream and downstream of the ribbon path and swings around the axis of the rotary shaft of the second roller (48) according to the tension on the ribbon traveling as guided by these rollers (47, 48). When the amount of swing is above or below a fixed vale, a ribbon feed motor (18) or a ribbon winding motor (19) is driven. Further, the ribbon tension detecting means (20, 21) are each provided with a wrinkle eliminating member adapted to contact an ink ribbon (13) so as to eliminate wrinkles formed in the ink ribbon (13).

Description

technical field [0001] The present invention relates to a ribbon conveying device of a printer using an ink ribbon. In particular, it relates to a printer using a transfer film tape, a tape tension detecting device thereof, and a tape conveying device provided with a wrinkle removing member on the tape tension detecting device. Background technique [0002] In a printer that transfers a film tape (hereinafter referred to as tape) using a thermal transfer film or the like, the tape and paper are crimped between the head and the platen and sent out. At this time, if the tension of the belt fluctuates, the transmission of the belt and the transmission of the paper will be inconsistent, and wrinkles will be generated on the belt or the belt will be rubbed by the paper, which will damage the quality of printing. [0003] In order to alleviate the fluctuation of the tension of the tape, in a conventional printer, as disclosed in Japanese Unexamined Patent Application Publication ...
