[Detailed description of the invention]

[0001]

INVENTION The present invention relates to a cutting device for cutting the print tape used in the tape printer and a tape <br/> word processing.

[0002]

2. Description of the Related Art Generally, a tape printer or a tape word processor is provided with a cutting device for cutting a tape after printing. This cutting device is constituted by a cutting table for receiving a printing tape and a cutter which comes into contact with and separates from the cutting table. When the printing tape is supplied to the cutting table, the cutter is driven to cut the printing tape on the cutting table. Things.

[0003] However, the cutting device tape printer
Since the printing tape is not supported on the cutting table, the printing tape is often floated on the cutting table and wavy in the thickness direction. If the cutter is operated in this state, the cutting position and the cutting angle become inaccurate, and moreover, it is necessary to apply excessive force to the cutter in order to cut the floating printing tape.

[0004]

The object of the present invention is to solve the above-mentioned drawbacks, and in particular, by fixing the printing tape on a cutting table in a tensioned state, the cutting position and the cutting angle can be made accurate, and
An object of the present invention is to provide a cutting device that can surely cut even a small force.

[0005]

Means for achieving the object] To achieve the above object, the cutting apparatus of the print tape according to the present invention, in the cutting device for cutting the print tape to be used for Tepupuri <br/> te, the print tape A cutting table for cutting, a cutter that moves in a direction substantially perpendicular to the cutting table and cuts the printing tape supplied on the cutting table, and a cutter that is disposed on both sides of the cutter. The printing tape is provided so as to be pressed against the printing tape surface prior to the cutting edge, and when pressed against the printing tape surface, moves the printing tape away from the cutter in a direction to tighten the cut portion of the printing tape. A guide portion.

It is preferable that the cutting edge of the cutter is formed in a V-shape or a V-shape in which a center portion is dented.

[0007]

According to the above construction, when the cutter is moved toward the cutting table together with the guide section after the printing tape is supplied on the cutting table, the guide section first contacts the printing tape surface on the cutting table. The printing tape is moved away from the cutter in a direction to tighten the cut portion of the printing tape. For this reason, the printing tape between the guide portions on both sides is tensioned and fixed, and then the cutting edge of the cutter is pressed against the printing tape, so that the printing tape is cut at an accurate cutting position and at an accurate cutting angle. , It is possible to reliably cut even with a small cutting force.

Further, since the force applied to the cutter itself is small, the durability of the cutter is improved.

[0009] The cutting edge of the cutter is V
When it is formed in the shape of a letter, the printing tape is cut from both sides to the center, so it is possible to reliably cut the printing tape with a much smaller cutting force than when the entire cutting edge hits the printing tape at the same time. it can.

The same applies to the case where the blade edge of the cutter is formed in a V-shape.

[0011]

FIG. 1 shows a printing tape cutting device.
The cutting device has been made to cut the print tape used in the tape printer, the cutting bench 1 for cutting a print tape a, a cutter unit b comprising a cutter 2 and the cutter guide member 3 which, cutter And a unit guide 4 for guiding the unit b.

[0012] cutting bench 1 is arranged in the vicinity of the print tape outlet of the tape printer (not shown). When an adhesive layer is formed on the back side of the print tape, a release layer (not shown) made of Teflon or the like is formed on the surface of the cutting table 1 so as not to adhere to the adhesive layer.

The cutter 2 moves so as to come into contact with and separate from the cutting table 1 at a substantially right angle, and cuts the print tape a supplied on the cutting table 1. The cutter body 2a is held by a holder 2b. It is made to let. An inclined surface 5 that is inclined with respect to the moving direction is formed on the tip side of the cutter 2 (the shoulder of the holder 2b). Also, the holder 2b
A pressing projection 6 is formed at the rear of the head. The cutting edge of the cutter body 2a may be formed in a V-shape.

The cutting edge of the cutter body 2a may be formed in a normal linear shape, but is preferably formed in a V-shape with a concave central portion as shown in FIG. Such a structure may be obtained by joining two cutters 2 cut diagonally to each other. Further, a cut 7 corresponding to the shape of the cutting edge is formed on the cutting table 1 in accordance with the cutting edge structure of the cutter 2.

Next, the cutter guide member 3 is made of a synthetic resin, has a housing portion 8 for housing the cutter 2, and has a through-hole 9 formed at the rear end portion through which the protrusion 6 of the cutter 2 penetrates. An opening 10 for projecting the cutting edge of the cutter 2 is formed at the tip. This opening 10 is provided with the cutter 2
The guide portion 11 swells on both sides of the front end portion. The base of the guide 11 is narrowed narrowly and the neck 12
Are formed, and the guide portion 11 is formed so as to be swingable about the neck portion 12. Also, a cutter 2 is provided inside the guide portion 11.
An engaging portion 14 that can be engaged along the inclined surface 5 is formed. The tip of the cutter 2 is normally housed so as to retreat to a position where it does not protrude from the guide portion 11. Note that a slip stopper 13 is attached to the tip of the guide portion 11.

Next, the unit guide 4 guides the cutter guide member 3 and the cutter 2 so as to move in the cutting direction.

According to the cutting device having the above-described structure, the projection 2 of the cutter 2 is pressed in the cutting direction after the printing tape a is supplied onto the cutting table 1, so that the cutter 2 and the cutter guide member 3 can be moved together. Approach one. Then, as shown in FIG. 2, when the non-slip 13 of the guide portion 11 of the cutter guide member 3 comes into contact with the printing tape a on the cutting table 1, the movement of the cutter guide member 3 is stopped, and the inclined surface 5 of the cutter 2 is stopped.
The engagement portion 14 inside the guide portion 11 of the cutter guide member 3
Engage. When the cutter 2 moves further in the cutting direction,
In conjunction with this, the engaging portion 14 slides along the inclined surface 5 of the cutter 2, so that the guide portion 11 moves away from the cutter main body 2 a around the neck portion 12 in the direction of tensioning the cut portion of the print tape. It swings and deforms. For this reason,
As shown in FIG. 3, the non-slip 13 also moves away from the cutter 2 in the direction of tensioning the cut portion of the print tape while being in contact with the print tape a. It is in a state and is fixed by the non-slip 13. Thereafter, the cutting edge of the cutter 2 is pressed against the printing tape a, so that the printing tape a is cut at an accurate cutting position at an accurate cutting angle, and can be reliably cut with a small cutting force.

In addition, since the cutting edge of the cutter body 2a is formed in a V-shape with a concave central portion, the print tape a is cut from both side ends toward the center.
Therefore, the printing tape a can be reliably cut with a much smaller cutting force than in the conventional case where the entire cutting edge simultaneously contacts the printing tape a. Cutter body 2
The same applies to the case where the blade edge of a is formed in a V-shape.

Although the above-described example is an example in which the guide portions 11 provided on both sides of the cutter 2 swing, one guide portion 11 does not necessarily need to swing.

FIGS. 5 and 6 show another example of a printing tape cutting device, in which a cutter 2 is fixed to the center of a cutter holder 2b, and guide portions 11a made of a soft material are arranged on both sides of the cutter body 2a. Fixed. The guide portion 11a is provided so as to come into contact with the surface of the printing tape a before the cutting edge of the cutter body 2a.

The cutting table 1 is also made of a soft material.
At the center thereof, a notch 15 for receiving the cutting edge of the cutter body 2a is formed. Further, when an adhesive layer is formed on the back side of the print tape a, the surface of the cutting table 1 is subjected to Teflon processing so as not to adhere to the adhesive layer on the back side of the print tape a.

In the above configuration, when the cutter main body 2a is brought close to the cutting table together with the guide section 11a after the printing tape a is supplied onto the cutting table 1, first the guide sections 11a on both sides are provided.
When the cutter body 2a stops in contact with the printing tape a on the cutting table 1 and moves further in the cutting direction, the leading end of the guide portion 11a is kept in contact with the printing tape a by the pressing force in conjunction with this. Although it is deformed, it is largely deformed in a direction in which the cut portion of the print tape a is tensioned away from the cutter body 2a. At the same time, the soft material constituting the cutting table 1 is also largely deformed in the direction in which the cut portion of the print tape is tensioned away from the cut portion 15. Therefore, the printing tape a between the guide portions 11a on both sides is also moved away from the cutter body 2a in a direction in which the cut portion of the printing tape is tightened, and is fixed in a tensioned state. Thereafter, the cutting edge of the cutter 2 is pressed against the printing tape, so that the printing tape a is cut at an accurate cutting position at an accurate cutting angle and can be reliably cut with a small cutting force.
