Abstract

PROBLEM TO BE SOLVED: To reduce the size of a storage space without the use of a gear by holding a correction tape supply reel and a base tape take-up reel on one shaft in an independently rotating manner from each other and connecting them by a frictional force in a mutually slippable manner, and taking up the base tape which is already through with its use for conveying the rotation of the supply reel to the take-up reel. SOLUTION: A take-up reel 4 is fitted into a shaft 2 firmly implanted in an outer enclosure 1A centered around the circular part and a supply reel 5 is fitted onto the take-up reel 4, both take-up reel 4 and supply reel 5 being rotatable. Further, a stepped part 51 is formed on the lower face of the reel 5 and a lever 52 is formed which overhangs elastically outward from the outer peripheral face of the stepped part 51 and is elastically brought into contact with the inner face of a circumferential protruding strip 41 on the upper face of the reel 4. Further, a transfer head 3 having a guide protruding strip for a correction tape T formed on both side edges is mounted on a pin 11 on the outer enclosure 1A. Next the correction tape T is take up from the left side of the reel 4 after passing around the tip of a draw-out head 3 from the right side of the reel 5 using pins 12, 13 as guides. The winding dia. of the reel 4 is made slightly larger than of the reel 5. Thus it is possible to prevent a change in the winding dia. by a take-up volume and the slackening of the tape due to its alippage from occurring.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer type character correcting device using a correction tape in which a base tape is coated with a correction paint.

[0002]

2. Description of the Related Art In a character correcting device of the above-mentioned type, a supply reel for a correction tape and a take-up reel are interlocked by a gear, and the take-up reel is rotated by rotating the supply reel by pulling out the correction tape. The structure is such that the base tape is wound on a take-up reel.

[0003] Such a conventional correction tool has a complicated structure since it uses gears, and the two reels are arranged side by side on one plane, so that the outer shape of the tool becomes large, and the outer shape of the tool is reduced to a reasonable size. However, there is a problem in that the size of the two reels is limited, and the initial length of the correction tape cannot be made too long. Also, since the two reels are connected by gears, the two reels rotate in opposite directions, and if the correction tape is pulled out from the left side of the supply reel, the base tape must be wound up from the left side of the take-up reel. However, the tape had to be wound around in a complicated manner in the instrument, and the resistance when winding the base tape was large, the rotational force of the take-up reel was insufficient, and the base tape was easily loosened. This phenomenon is necessary to change the rotation angle ratio between the supply tape and the take-up tape as the ratio between the winding diameter of the correction tape and the take-up diameter of the base tape gradually changes. This occurs because slippage occurs between the take-up tape and the gear.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a transfer-type character correcting device which does not use gears, has a small space for accommodating a mechanism, and can easily route a tape.

[0005]

A supply reel and a take-up reel for the correction tape are superposed on one shaft in the apparatus and held so as to be rotatable independently of each other. Then, the correction tape drawn from the supply reel is guided to the take-up reel beyond the transfer head provided at the tip of the instrument, and the rotation of the supply reel when the correction tape is drawn from the supply reel is transmitted to the take-up reel. Used tape was wound up.

[0006]

Since the supply reel and the take-up reel are stacked in two stages, the storage space can be reduced to one reel, and the equipment can be reduced in size. If the size is the same, the initial correction tape length can be increased. Since the supply reel and the take-up reel rotate in the same direction by direct connection via frictional force, the correction tape pulled out from the left side of the supply reel passes through the transfer head, and then is wound on the take-up reel from the right side of the take-up reel. So that the path of the tape is
It is a simple form that only includes turns, and the winding resistance of the base tape can be reduced.

[0007]

FIG. 1 shows one embodiment of the present invention. In the figure, 1A and 1B are outer casings of the device. The shaft 2 is fixed to the center of the circular portion of the outer casing 1A. Reference numeral 3 denotes a transfer head having a triangular tip portion and a handle, and a hole in a side protruding portion of the handle is fitted into a pin 11 set in the outer casing 1A, so that the transfer head 3 slightly moves left and right. It can be installed leaving a degree of freedom. Protrusions are formed on both sides of the transfer head 3 to guide the correction tape as shown in the figure. A take-up reel 4 is lightly rotatably fitted on the shaft 2. The supply reel 5 is also lightly rotatably fitted thereon. The supply reel has a step portion 51 formed on the lower surface, and a lever 52 is provided on the outer peripheral surface of the supply reel so as to elastically project outward. The lever 52 is configured to elastically slidably contact the inner surface of the circumferential ridge 41 formed on the upper surface of the take-up reel 4. With this structure, the take-up reel 4 and the supply reel 5 slip by frictional force. As possible, they rotate in the same direction.

The correction tape T is pulled out from the right side of the supply reel 5, rotates around the tip of the transfer head 3, and is wound on the take-up reel from the left of the take-up reel 4. FIG. 2 is a plan view showing the running state of the tape T in this embodiment.
In this example, the width direction of the tape is perpendicular to the plane of the drawing at the place where the tape is pulled out from the supply reel and the place where the tape is taken up by the take-up reel.
The correction head 3 is twisted so as to be parallel to the plane of the drawing. In this way, the tape drawn from the supply reel for guiding the tape T runs in contact with the pins 13 erected on the outer casing 1A, and the base tape to be wound runs in contact with the pins 12.

At the start of use of the device, the winding diameter of the take-up reel 4 is made slightly larger than the tape winding diameter of the supply reel 5. In use, the two reels are rotated substantially without slippage, and the length of the tape just pulled out from the supply reel 5 is wound on the take-up reel. The tape remains taut because it is slightly larger than the diameter. When the remaining amount of the correction tape decreases, the amount of rotation of the supply reel with respect to the consumption of a fixed length of tape increases, and the winding diameter of the winding reel increases with the winding of the base tape. The capacity exceeds the feed length of the tape, which is compensated by the slip between the supply reel and the take-up reel. This slip mechanism is naturally necessary even in the conventional example using gears, but when using gears, the supply reel and the take-up reel are arranged on the same plane, so that the take-up reel has a large diameter in advance. Since there is no space to take up and winding with a small diameter, the change rate of the winding diameter of the take-up reel at the beginning and end of use of the device becomes larger than in the case of the present invention, near the end of use of the device In this case, the amount of work when the supply reel rotates against the friction between the supply reel and the take-up reel becomes large, and at this time, the correction tape cannot be pulled out easily. If the friction between the supply reel and the take-up reel is reduced to avoid this, the take-up reel will not have enough force to tension the correction tape at the beginning of use of the device, and the tape will tend to be loosened. In this regard, in the present invention, the outer diameter of the take-up reel can be increased, so that the slip between the supply reel and the take-up reel does not increase so much even at the end of use of the device, and the correction tape is maintained throughout the use of the device. Can be given appropriate tension.

[0010]

The character correction device of the present invention has a simple structure because it does not use gears, and the correction tape supply reel and the take-up reel are arranged on the same axis so that both reels in the device can be used. If the occupied space is smaller than the conventional example, and the size of the device itself is about the same as this type of conventional device,
Since both reels can be made larger in diameter, the capacity of the correction tape increases, and as described in the preceding paragraph, the tension applied to the correction tape by the frictional connection between the two reels becomes stable, and the tape does not loosen.
