DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a tape printer according to an embodiment of the present invention will be described with reference to the accompanying drawings. This tape printer has a function of performing desired printing on a printing tape by key input and cutting a printed portion of the printing tape, and the cut piece of tape is, for example, a document file or a wiring cable. Used as a label to stick. That is, the tape printing apparatus creates a label on which characters are printed from a plain printing tape. In this case, the plain print tape and ink ribbon that are consumables are accommodated in the tape cartridge and supplied to the apparatus main body via the tape cartridge.
[0022]
As shown in FIG. 1, the tape printer 1 is of a handy type, and an outer shell of the apparatus body 2 is constituted by an apparatus case 3. A key input unit 4 is disposed at the front portion of the tape printer 1, and an opening / closing lid 6 having a liquid crystal display 5 formed on the surface is disposed at the rear portion. As shown in FIGS. 2 and 3, a cartridge mounting portion 8 for mounting the tape cartridge 7 is disposed inside the opening / closing lid 6. Further, a tape discharge port 10 is formed on the left side of the device case 3 to communicate the cartridge mounting portion 7 with the outside of the device, and a cutter 11 for cutting the sent printing tape T faces the tape discharge port 10. (See FIGS. 1 and 2).
[0023]
On the other hand, the cartridge mounting portion 8 includes a print head 14 covered with a head cover 13, a platen shaft 15 facing the print head 14, a take-up shaft 16 for winding an ink ribbon, and a guide protrusion for guiding the mounting of the tape cartridge 6. 17 is erected. A platen 18 that engages with the platen shaft 15 is provided in the tape cartridge 7 (see FIG. 1).
[0024]
In this case, the platen 18, the platen shaft 15, and the winding shaft 16 constitute a tape feeding mechanism 21 together with related parts described later, and the cutter 11 constitutes a tape cutting mechanism 22 together with related parts described later. The tape feeding mechanism 21 and the tape cutting mechanism 22 are operated by the same drive source (motor) via the power transmission mechanism 23 and the clutch mechanism 24 arranged below the cartridge mounting portion 7. (Details will be described later). A tape piece holding mechanism 25 is incorporated in the tape discharge port 10 so that the cut tape piece Ta can be pressed and held in the tape discharge port 10 (details will be described later).
[0025]
When producing a label with this tape printer 1, first, after opening the opening / closing lid 6, the tape cartridge 7 is mounted on the cartridge mounting portion 8 from above. When the cartridge 7 is mounted, the open / close lid 6 is closed to place the tape printer 1 in a print standby state. Next, a desired input is performed by operating the key input unit 4 while viewing the liquid crystal display 5. When a desired input is confirmed on the liquid crystal display 5, the key input unit 4 is further operated to instruct a printing operation.
[0026]
When a printing operation is instructed, the tape feeding mechanism 21 starts the printing tape T and the ink ribbon of the tape cartridge 6 at the same time, and the print head 14 performs desired printing on the printing tape T. As the printing operation proceeds, the ink ribbon is wound up in the cartridge 6, and the printed printing tape T is sent out of the apparatus from the tape discharge port 10. When the printing is completed, the feeding of the blank portion is performed, and then the printing tape T and the ink ribbon are stopped. Subsequently, the cutter 11 is operated by the tape cutting mechanism 22 to cut the printing tape T. The cut tape piece Ta is held in the tape discharge port 10 by the tape piece holding mechanism 25 in a state where it can be pulled out.
[0027]
Next, with reference to FIG. 4 and FIG. 5, the power system having the tape feeding mechanism 21 and the tape cutting mechanism 22 as output ends will be described in detail. This power system is selectively connected by a motor 31 that is a power source, a drive unit 32 that includes a gear train connected to the main shaft of the motor 31, a clutch mechanism 24 that is connected to the drive unit 32, and the clutch mechanism 24. A power transmission mechanism 23 including a feed mechanism side gear train 33 and a cutting mechanism side gear train 34, a tape feed mechanism 21 connected to the feed mechanism side gear train 33, and a tape cutting mechanism connected to the cutting mechanism side gear train 34. 22. The motor 31, the drive unit 32, the clutch mechanism 24, and the power transmission mechanism 23 are incorporated in a base frame 26 disposed in the lower space of the cartridge mounting unit 8.
[0028]
The motor 31 is configured to be capable of forward and reverse rotation. When the motor 31 rotates forward, the rotational power is transmitted from the drive unit 32 to the clutch mechanism 24, and the clutch mechanism 24 is switched to the feed mechanism side gear train 33 for further rotation. Power is transmitted to the feed mechanism side gear train 33 and the tape feed mechanism 21. As a result, the platen shaft 15 and the take-up shaft 16 rotate to simultaneously feed the printing tape T and the ink ribbon. On the other hand, when the motor 31 rotates in reverse, the rotational power is transmitted from the drive unit 32 to the clutch mechanism 24, the clutch mechanism 24 is switched to the cutting mechanism side gear train 34, and the rotational power is further switched to the cutting mechanism side gear train 34 and the tape cutting mechanism. 22 is transmitted. As a result, the cutter 11 performs a cutting operation to cut the printing tape T.
[0029]
The motor 31 is constituted by a DC motor, and is fixed to the base frame 26 with a slight inclination in consideration of the space efficiency of the device case 3. The drive unit 32 includes a worm 36 fixed to the main shaft of the motor 31, a worm wheel 37 that meshes with the worm 36, a wide gear (output gear) 38 that is coaxially fixed to the lower side of the worm wheel 37, and a worm wheel 37. And a rotary shaft 39 to which a wide gear 38 is fixed (see FIG. 6). The rotational power of the motor 31 is input from the wide gear 38 to the clutch mechanism 24 via the worm 36 and the worm wheel 37.
[0030]
As shown in FIG. 6, the clutch mechanism 24 is supported by a planetary gear 40 that meshes with the wide gear 38, and the planetary gear 40 is rotatably supported at an end portion thereof and is rotatably supported by the rotary shaft 39. And a carrier 41. When the motor 31 rotates forward, the rotating shaft 39 rotates together with the worm wheel 37 and the wide gear 38 following this. When the rotating shaft 39 rotates, the carrier 41 is rotated (vibrated) by friction so that the planetary gear 40 meshes with the input gear (input gear) 42 of the feed mechanism side gear train 33. The rotation of the wide gear 38 is transmitted to the planetary gear 40 meshing therewith, and the planetary gear 40 is transmitted to the input gear 42 at the moment when the planetary gear 40 meshes with the input gear 42 to rotate it (see FIG. 5A). Similarly, when the motor 31 rotates in the reverse direction, the rotating shaft 39 rotates in the reverse direction, and the carrier 41 rotates to mesh the planetary gear 40 with the input gear (input gear) 43 of the cutting mechanism side gear train 34. The rotation of the wide gear 38 is transmitted to the planetary gear 40, and the planetary gear 40 is transmitted to the input gear 43 at the moment when the planetary gear 40 meshes with the input gear 43 to rotate it (see FIG. 5B).
[0031]
The feed mechanism side gear train 33 includes the input gear 42, a first intermediate gear 45 that is coaxially fixed to the upper side of the input gear 42, a second intermediate gear 46 that meshes with the first intermediate gear 45, and a coaxial A branch gear 47 fixed below the second intermediate gear 46, a winding gear 48 on the winding shaft 16 side meshing with the branch gear 47, a reduction gear 49 and a platen gear on the platen shaft 15 side similarly meshing with the branch gear 47 And 50.
[0032]
The rotational power of the motor 31 input to the input gear 42 is branched by the branch gear 47 via the first and second intermediate gears 45 and 46 to rotate the winding gear 48 and the platen gear 50. When the rotational power is input to the platen gear 50 by the user pulling out the printing tape T or the like, the input gear 42 pushes the planetary gear 40 to cut off the power and thus does not receive the load of the motor 31. In this state, the winding gear 48 is rotated via the branch gear 47. As a result, the ink ribbon is wound up as the printing tape T is pulled out, and the slack of the ink ribbon is prevented.
[0033]
The cutting mechanism side gear train 34 has the input gear 43, an input bevel gear 52 coaxially fixed to the upper side of the input gear 43, an output bevel gear 53 meshing with the input bevel gear 52, and a length in which the output bevel gear 53 is fixed to one end. A shank shaft 54, an intermediate gear 55 fixed to the other end of the shaft 54, and a cutter gear 56 that meshes with the intermediate gear 55. The rotational power of the motor 31 input to the input gear 43 is transmitted to the shaft 54 via both bevel gears 52 and 53, and further the cutter gear 56 is rotated from the shaft 54 via the intermediate gear 55.
[0034]
The tape feed mechanism 21 includes a platen 18 that rolls and contacts the printing tape T and the ink ribbon, a platen shaft 15 that rotates the platen 18, and a winding shaft 16 that winds up the ink ribbon. The platen 18 is incorporated in the tape cartridge 7, and when the tape cartridge 7 is mounted on the cartridge mounting portion 8, the platen 18 engages with the platen shaft 15. The platen shaft 15 is coaxially fixed to the platen gear 50 in a cantilever manner, receives the rotation of the platen gear 50, rotates, and rotates the platen 18 engaged therewith. The take-up shaft 16 is coaxially fixed to the above-described take-up gear 48 in a cantilever manner, receives the rotation of the take-up gear 48, rotates, and rotates the take-up core of the ink ribbon engaged therewith. . The take-up shaft 16 is a sliding shaft and takes up the ink ribbon while sliding and rotating as appropriate.
[0035]
As shown in FIG. 7, the tape cutting mechanism 22 includes a scissors-type cutter 11 and a crank disk 58 that engages with the cutter 11 and performs a cutting operation thereof. The cutter 11 is formed by rotatably connecting a fixed blade 61 and a movable blade 62 with a support shaft 63, and the movable blade 62 performs a cutting operation with respect to the fixed blade 61. The fixed blade 61 is integrally formed by a blade main body 65 and a cutter arm 66 extending from the base portion of the blade main body 65 at a substantially right angle, and is fixed to the base frame 26 at the portion of the cutter arm 66. An oil absorber 67 containing silicon oil and a static elimination brush 68 for grounding static electricity are attached to the plate body 65 of the fixed blade 61 to prevent adhesion of the adhesive on the printing tape T (see FIG. 4). ).
[0036]
The movable blade 62 is integrally formed by a blade main body 70 and a cutter arm 71 extending from the base of the blade main body 70 at a substantially right angle. The movable blade 62 engages with the crank disc 58 through a long hole 72 formed in the cutter arm 71. ing. The crank disc 58 includes a disc main body 74 and a crank pin 75 provided at an eccentric position of the disc main body 74, and the cutter gear 56 is fixed to the back surface of the crank disc 58 on the same axis. (See FIG. 4). The crank pin 75 is engaged so as to be inserted into the elongated hole 72 of the cutter arm 71. That is, the crank disc 58 and the cutter arm 71 constitute a swing crank mechanism, and when the crank disc 58 rotates, a cutting completion position (forward movement end position) where the blade body 70 cuts into the fixed blade 61, and A cutting operation (reciprocating rotation) is performed between the cutting standby position (return end position) farthest from the fixed blade 61.
[0037]
As will be described in detail later, the switch end 105a of the detection switch 105 is in sliding contact with the outer peripheral surface of the crank disk 58, and the detection switch 105 is turned on at a part of the outer peripheral surface of the crank disk 58. An arcuate recess 76 is formed.
[0038]
Next, the tape piece holding mechanism 25 will be described in detail with reference to FIGS. 8 and 9. As shown in FIG. 8, the tape discharge port 10 is formed in the device case 3, and includes a slit part 81 whose upper end is opened and an expanding part 82 that extends outward from the slit part 81. It is configured. The above-described cutter 11 is built in the portion of the apparatus case 3 that forms the slit portion 81, and the cutter 11 performs a cutting operation with the substantially center line position of the slit portion 81 as a cutting line. Further, in the opening wall 83b on the movable blade 62 side of the apparatus case 3 forming the expanding portion 82, a tape piece holding mechanism 25 for pressing and holding the cut tape piece Ta on the opening wall 83a on the fixed blade 61 side is incorporated. Has been.
[0039]
The tape piece holding mechanism 25 includes a holding claw 91 that presses and holds the tape piece Ta, a case-like claw holder 92 that holds the holding claw 91 so as to advance and retreat, and a coil that urges the holding claw 91 toward the opening wall 83a. And a spring 93. The holding claw 91 is integrally formed of a claw body 94, an engagement projection 95 provided on the inner side of the base of the claw body 94, and a rod portion 96 that linearly extends from the base end of the claw body 94. The holding claw 91 is supported by the claw holder 92 at two positions on the front and rear sides of the claw body 94 and the rod portion 96 so as to be able to advance and retreat. Between the abutting holding position and the holding releasing position for immersing in the opening wall 83b on the movable blade 62 side, the protrusion is made to protrude from the opening wall 83b.
[0040]
The front end surface of the holding claw 91 is formed obliquely in accordance with the wall surface of the opening wall 83a on the fixed blade 61 side. That is, the front end surface of the holding claw 91 is formed in a complementary shape so as to come into contact with the wall surface of the opening wall 83a on the fixed blade 61 side. A coil spring 93 is attached to the rod portion 96, and one end of the coil spring 93 abuts on the base end of the claw body 94 and the other end abuts on the inner surface of the claw holder 92 so that the holding claw 91 is moved forward. Energized. The holding claw 91 biased in this way is in contact with the ridge side of the movable blade 62 at its engaging projection 95. Accordingly, the holding claw 91 advances and retreats according to the cutting operation (reciprocating rotation) of the movable blade 62 and appears and disappears from the opening wall 83b on the movable blade 62 side. Note that the holding claw 91 is preferably configured to reach the holding position immediately before the movable blade 62 reaches the cutting completion position.
[0041]
In this case, the holding claw 91 reaches the opening wall 83a on the fixed blade 62 side at the moment when the cutter 11 cuts the printing tape T (not strictly), and the tape piece Ta after cutting is separated from the wall surface of the opening wall 83a. Hold between. Further, the state where the tape piece Ta is sandwiched is maintained until the next cutting operation. Therefore, in this embodiment, in order to maintain the holding claw 91 in the holding position, the cutting operation of the movable blade 61 is stopped at the cutting completion position, and the next cutting operation is started from the cutting completion position.
[0042]
Here, with reference to FIG. 2, the controller for stopping the movable blade 62 at the cutting completion position will be described. The controller (control means) includes a CPU 101 that performs overall control of the motor 31 and the input / output device, and a detector 102 that detects the cutting operation position of the movable blade 62. The detector 102 includes an encoder 104 attached around the main shaft of the motor 31 and a detection switch 105 arranged around the crank disk 58 of the tape cutting mechanism 22. The encoder 104 detects the rotation angle of the motor 31, and the detection switch 105 detects the cutting standby position of the movable blade 62 in cooperation with the recess 76 of the crank disk 58.
[0043]
When the crank disk 58 rotates and the switch end 105a of the detection switch 105 falls into the recess 76 of the crank disk 58, the detection switch 105 is turned on and the detection signal is input to the CPU 101. The CPU 101 resets the encoder 104 based on this detection signal, and then stops the motor 31 when the encoder 104 reaches a rotation angle corresponding to 180 ° rotation of the crank disc 58. As a result, the movable blade 62 stops at the cutting completion position. That is, the cutting standby position is set as the home position of the cutter 11, and the movable blade 62 is stopped when the cutting standby position is rotated from the cutting standby position to the cutting completion position. Then, in response to the next print command, the movable blade 62 is returned to the cutting standby position and is made to stand by. When printing is completed, the movable blade 62 is rotated again to the cutting completion position.
[0044]
As described above, since the cut tape piece Ta can be held in the tape discharge port 10 by the tape piece holding mechanism 25, this does not cause troubles such as twice cutting and jamming of the tape piece Ta. Can be used as appropriate. Therefore, it can be made suitable for the handy type tape printer 1 that is taken out to the work site and used. In this case, since the holding operation of the holding claw 91 is performed using and interlocking with the cutting operation of the movable blade 62, the structure can be simplified and the tape piece Ta is attached to the tape discharge port 10. It can be held securely.
[0045]
In the tape piece holding mechanism of the embodiment, the holding claw 91 is moved to hold the tape piece. However, a structure in which a brush, a film, or the like is fixed so as to face the tape discharge port 10 may be used. .
[0046]
【The invention's effect】
