Description

Description: TECHNICAL FIELD The present invention relates to a tape joining device used for manufacturing a magnetic tape cassette, and particularly prints a symbol for identifying the manufactured magnetic tape cassette. The present invention relates to a tape joining device with a printing function having a function to perform.

(Prior Art) Magnetic tape cassettes used in video cassette recorders are characterized by being manufactured in large quantities by specialized businesses. On the other hand, those companies make a lot of efforts to control the quality of the manufactured magnetic tape cassettes.

When a defective magnetic tape cassette is produced, the business operator must first investigate the cause of the defective product. The business operator puts an identification mark on each magnetic tape cassette so that the name of the magnetic tape cassette recovered from the market as a defective product can be traced.

As a technique for attaching an identification mark to each individual magnetic tape cassette, for example, the technique disclosed in Japanese Patent Publication No. 57-36660 is known. Here, an apparatus for manufacturing a magnetic tape cassette while printing a symbol peculiar to a leader tape is shown.

(Problems to be solved by the invention) The symbols individually printed on the conventional magnetic tape cassette are
It had the drawback that it was not durable and could not withstand long-term use.

The reason is that the symbol attached to the magnetic tape cassette is
This is because it is exposed. That is, when the ink is directly printed on the leader tape, the printing is worn out while the magnetic tape cassette is used.

(Means for Solving Problems) In order to solve the above problems, the present invention provides a tape for joining cut ends of a conventional tape with a splicing tape having semitransparent and one side having an adhesive surface. A splicing tape reel that holds the reel of the splicing tape improved, a feeding unit that feeds the splicing tape, a holding unit that holds the tip of the splicing tape fed from the splicing tape feeding unit, and the feeding unit. A tape joining device with a printing function, comprising a printing means for printing a symbol on the adhesive surface of the splicing tape stretched between the means and the holding means.

(Operation) In the tape joining device with a printing function, the printing means prints a symbol on the splicing tape while the splicing tape is fed from the supply means to the holding means. The printing is made on the adhesive surface side of the splicing tape. This step of printing is done before the step of applying the splicing tape to the cut end of the tape. As a result, the printed portion is located between the tape to be joined and the surface of the splicing tape and is not exposed to the outside. The printed symbols are nevertheless easily readable by transmission from the surface of the splicing tape.
