Description

[Detailed description of the invention] The present invention forms dies with various characters or symbols on the periphery of a disc, provides radial punches to face each die, and rotates the disc to create the desired shape. The present invention relates to a tape feeding device for a tape writer that sequentially engraves characters or symbols on a synthetic resin tape.

In other words, when using such a tape writer to engrave kana characters with voiced or semi-voided marks, the die for the kana characters with voiced marks or other marks is first moved to a predetermined position and engraved, and then the die is sent to the tape. It is necessary to move a die such as a dakuten (dakuten) and stamp it, or vice versa, without applying a .

However, in a tape writer, the tape is fed simultaneously by operating the embossing lever, so the above operation requires a blank feeding mechanism.

The present invention provides a device that can perform this empty feeding with an extremely simple structure.

Fig. 1 is a side view of a part of the embodiment of the present invention, Fig. 2 is a sectional view taken along line A-A in Fig. 1, and Figs. 3 and 4 are B in Fig. 2.
-B and CC sectional views.

Dies with various characters or symbols are formed on the periphery of the lower surface of the disk 2 rotatably attached to the housing 1 in this manner, and a radial punch 3 is placed opposite each die.

In addition, a lever 5 provided with an anvil 4 is supported by a shaft 6 and pressed by a spring 7, and the tip of a synthetic resin tape 8 housed in the housing 1 is inserted from the gap between the die and the punch 3 at the periphery of the disk 2. There is a drawer on the outside.

In addition, a ratchet 9 and a feed roller 1 with teeth on the circumferential surface
0 are arranged coaxially and integrally formed, a part of the tape 8 is inserted between the roller 10 and the fixed base 11, and the roller 10 is pressed against the tape 8 by a metal plate spring 12,
In addition, the claw 13 of the lever 5 and the claw 14 for preventing reverse rotation attached to the housing 1 are engaged with the ratchet 9.

In other words, when lever 5 is pushed in the direction of arrow a, anvil 4
Since the punch 3 is pressed against the die, characters, symbols, etc. are stamped on the tape 8 inserted between them.

Next, when the lever 5 is released, the force of the spring 7 returns it to the state shown in the figure, at which time the ratchet 9 rotates by a certain angle and the tape 8 is fed out by the feed roller 10 by a certain distance.

In such a tape writer, the ratchet 9 is rotatably supported by loosely fitting the protrusion 15 of the housing 1 into the shaft hole formed at the end of the ratchet 9, and the roller 10 is provided with a conical shaft at the end. A shaped shaft hole 16 is formed, and the tip of a push button 17 for idle feed fitted into the housing wall is opposed to the conical surface of the shaft hole, and a spring 18 is placed between the push button and the feed roller.
It is suspended.

That is, since the tip of the push button 17 is opposed to the conical surface of the shaft hole, the ratchet 9 and roller 10 are supported eccentrically, and a projection 19 is provided on the shaft of the push button 17 to prevent rotation. .

In the above-mentioned device, when the push button 17 is pushed in the direction shown by the arrow in FIG.
is inclined as shown by the dotted line, and the roller 10 is separated from the tape 8.

Therefore, when the lever 5 is operated in this state, the tape 8 is engraved and the ratchet 9 and roller 10 are rotated, but the tape remains in a stopped state without being disturbed.

In other words, when stamping a character with a voiced point, etc., press the push button and operate the lever 5 to stamp a character without a voiced point, for example, and then release the push button and operate the lever again. Engraving marks, etc.

As explained above in the embodiments, the present invention has one end of the ratchet and roller for tape feeding swingably supported, a conical shaft hole provided at the other end, and the tip of the push button facing a part of the shaft hole. It was supported eccentrically.

Therefore, the tape can be fed idly with an extremely simple structure.
