A step 52 having a thickness e that intersects is provided. The step portion 52 is set to be slightly above the lower edge of the outlet groove 51. A push button 48 made of synthetic resin is attached to one longitudinal end of the operating lever 45, and a spring of a biasing spring 49 mounted between the other end of the operating lever 45 and the frame 21. Fixed blade 4 by force
The cutting blade surface 44a of the rotary blade 44 with respect to the cutting blade surface 43a of 3
It is biased so that a is greatly expanded by an angle θ1. Further, when the movable blade 44 moves in the closing direction, the synthetic resin actuating body 5 that rotates integrally with the operation lever 45 is moved.
A relief switch (not shown) is brought into contact with the sensor arm portion 50a of No. 0 to stop the rotation of the tape drive motor 24 so as to prohibit the feeding of the tape 10 in the cassette 4.

The central axis line 46 of the rotary support shaft 46 is
a is a fixed blade 43 as can be understood from FIG. 6 and FIG.
The cutting blade surface 43a is separated from the cutting blade surface 43a in the direction of the rotary blade 44, and is located near the rear surface of the rotary blade 44. Further, as shown in FIG. 10, the bottom plate 2a of the lower case 2 is provided below the cutting device 42 so as to extend substantially parallel to the cutting blade surface of the fixed blade 43 or / and the rotary blade 44. A plurality of slits 53 for removing chips are provided.

With this structure, the tape 10 delivered from the cassette 4 passes through the outlet groove 51 and is discharged to the outside. When the short-sized portion of the tip of the tape 10 is cut, the chips of the tape 10 are separated by the step portion 52.
It can be discharged smoothly from the outlet groove 51 to the outside of the cases 2, 3. Should the bottom case 2 of the lower case 2 have a tape 10
Even if the chips are dropped, they can be discharged from the slit 53 to the outside of the case. Therefore, it is possible to avoid a situation in which the cutting operation of the tape 10 is hindered or the feeding of the tape 10 is hindered by the accumulation of the tape chips in the vicinity of the outlet groove 51. The tape cutting device of the present invention has a structure in which the connecting member and the rotary blade 44 are reciprocally rotated via a drive motor and a power motor mechanism (not shown) instead of driving the rotary blade 44 by the operation lever 45. It may be.

As shown in FIG. 10, the length of the tape feed drive cam 23 or its rotation support shaft is extended at a position close to the tip of the fixed blade 43 to remove the cassette 4 from the storage section 5. In this state, the operator's finger does not enter in the direction of the fixed blade 43, the finger touches the cutting edge surface 43a of the fixed blade 43, or the push button 48 is inadvertently pressed to rotate the rotary blade 44. You can prevent your fingers from getting caught.

Further, as shown in FIG. 11, a fastening connecting screw 54 for preventing the lower case 2 and the upper case 3 from coming off.
In addition, if one end of a chain (not shown) is fastened together and the other end of this chain is fixed to a table or the like at a display place,
It is possible to prevent the printing tape making device 1 from being stolen at the time of display. Furthermore, as shown in FIGS. 11 and 12,
On the bottom plate 2a of the lower case 2, a battery cover plate 5 that covers the lower surface of the battery storage portion 55 for storing the dry battery 57 for power supply.
6 is configured so that it can be detachably attached via the engaging portions 58 and 59, and the downwardly-inflated portion 56a of a part of the battery cover body 56 is formed on the lower surface of the circumference of the cylindrical dry battery 57. If it is formed so as to project downward in a circular arc shape so as to directly support the above, it is not necessary to project a separate foot downward on the bottom plate 20a of the lower case 2 as in the conventional case, and the downward expansion portion 56 can be formed.
By directly supporting the lower circumferential surface of the dry battery 57 while a can be used instead of the foot,
It is possible to prevent useless space from being formed in the height direction of the lower case 2, reduce the height of the upper case 3 to the upper surface, and to make the printing tape creating apparatus 1 compact.
