Abstract

PURPOSE:To enable a single main printer system to handle tape widths by providing a tape feed device which guides a tape member to a position in a vertical run direction and at the same time, feed a tape. CONSTITUTION:The subject printer consists of a tape feed roller 31 with a deformed hole 31-1 which engages with a tape feed transmission gear shaft 25, flanges 33-1, 33-2 which guide the run of a transparent film 28 and a duplicat ed tape 30, and a tape holding roller energized in an arrow (D) direction which is incorporated in a tape cassette. If a motor gear 19 is rotated in an arrow(A) direction, a ribbon winding gear 23 rotates in an arrow(B) direction. In addition, a tape feed transmission gear 24 rotates in an arrow (C) direction. If the tape of feed transmission gear 24 rotates in the arrow(C) direction, a tape feed roller 31 rotates in the arrow(C) direction. Therefore, the transparent film 28 which adheres to the duplicated tape 32 is fed in an arrow(E) direction.

Description

[Detailed description of the invention]

[Field of Industrial Application] The present invention relates to a printing device, and more particularly to a tape printer that exclusively prints on tape stored in a tape cassette. [Prior Art] Conventionally, in this type of technology, a tape feeding means suitable for the tape width was attached to the printer body. [Problems to be Solved by the Invention] However, with the above-mentioned conventional technology, only a cassette containing a tape having a tape width suitable for the tape feeding means attached to the main body can be used, and cannot accommodate multiple tape widths. There was a problem. The present invention has been made to solve these shortcomings, and it is an object of the present invention to provide a tape printer that is adaptable to a plurality of ribbon widths. [Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention has a tape member wound in at least one type of roll shape, and the vertical position of the tape member is controlled. It is characterized by comprising a tape cassette having a tape feeding means for guiding and feeding the tape, and a shaft attached to the main body of the printer and functioning to drive the tape feeding means. [Function] According to the above configuration of the present invention, a tape feeding means suitable for the tape width is provided inside the tape cassette, and even if the tape width is changed, a tape feeding means suitable for the tape width is always provided. Can be done.
