Description of the Related Art Conventionally, in a printing device that prints a desired character string on a long printing sheet such as a tape, the printing sheet can be attached to and detached from the printing device in a cartridge format, which facilitates replacement work. I am trying. This type of print sheet cartridge stores long print sheets in a compact size, and in order to facilitate smooth supply to printing equipment, the print sheets are wound and stored on a cylindrical sheet core and are required for printing. It is common to use it by feeding out an appropriate amount. Further, it is also known that a flange portion is provided on the sheet core so that the wound and stored printed sheet does not come apart, a double-sided sheet is attached to the inner surface of the sheet core, and the edge of the printed sheet is attached to the double-sided sheet. There is.

On the other hand, a printing apparatus using such a print sheet cartridge generally has a mechanism for cutting a long print sheet. The cutting mechanism is provided in the vicinity of the print sheet discharge port, and cuts the print sheet at a desired position by operating a cutting lever or the like.

[0004]

However, when the print sheet cartridge is handled as a single unit, there is a problem that the sheet core rotates due to vibration or the like and the leading end of the print sheet gets into the cartridge case. . Once the print sheet got inside the cartridge case, it was not easy to remove it.

In order to take out the print sheet that has entered the cartridge case, the cartridge case must be opened. Normally, the print sheet cartridge also contains an ink ribbon for printing and the like. If the lid is forcibly opened, the ink ribbon or the like may be loosened or may deviate from the regular storage position, possibly damaging the cartridge itself.

If the user tries to print by mounting the print sheet cartridge in which the leading edge of the print sheet has entered the cartridge case without knowing it, the print sheet is nipped and conveyed between the platen and the print head. It has also been pointed out that the print sheet that is printed may become jammed in the cartridge and cause a malfunction of the printing device.

On the other hand, in a printing apparatus in which such a print sheet cartridge is mounted, if a cutting mechanism is used during printing, there is a problem that the conveyance of the print sheet is hindered and the print sheet is jammed in some cases.

The print sheet cartridge and the printing apparatus of the present invention solve these problems and solve the problem of the print sheet accidentally entering or clogging.
It was made for the purpose of solving the problem in using a printing device equipped with a print sheet cartridge.

BEST MODE FOR CARRYING OUT THE INVENTION In order to further clarify the structure and operation of the present invention described above, a tape cartridge which is a preferred embodiment of the present invention and a tape writer which detachably incorporates the tape cartridge and prints on the tape. Will be described. 1 is a plan view showing the appearance of the tape writer 1, FIG.
Is a right side view of the same. 3 is a plan view showing an assembled state of the tape cartridge 10 mounted on the tape writer 1, and FIG. 4 is a bottom view of the same. In the present embodiment, the ink ribbon and the tape printed using the ink ribbon are housed in the same cartridge, so this cartridge corresponding to the print sheet cartridge will be referred to as a tape cartridge hereinafter.

As shown in the figure, the tape writer 1 includes a main body case 50H for accommodating various parts, an input section 50C having 63 input keys, a main body cover 50K which can be opened and closed,
Display unit 50D visibly provided under the body cover 50K for displaying character strings and other information, body cover 50K
Tape cartridge 1 provided at the upper left of the main body
Cartridge mounting part 50A to which 0 is detachably mounted
(Not shown in FIG. 1). A window 50L for confirming the mounting of the tape cartridge 10 on the main body cover 50K
And a window 50M capable of directly looking at the display section 50D are provided, and a transparent plastic plate material is fitted into both windows 50L and 50M.

When using this tape writer 1,
First, open the main body cover 50K to open the cartridge mounting portion 5
Attach the tape cartridge 10 to 0A and cover the main body 5
Close 0K. After that, the power switch 50J provided on the right side of the main body is operated to turn on the power, and the input unit 50C
Enter the character you want to print from. When the input character string is converted into kana-kanji characters or the like as necessary and a predetermined key is operated to instruct printing, the tape T supplied by the tape cartridge 10 is printed by the thermal transfer type printer unit 50B. . The printed tape T is ejected from the tape ejection port 10A provided on the left side surface of the tape writer 1. The tape T used in this example has a printing surface processed to improve the placement of the ink by thermal transfer, and a peelable peeling tape is attached to the adhesive back surface. Therefore, by cutting the printed tape with a built-in cutter and peeling off the peeling tape on the back surface, the tape T on which characters and symbols are printed can be attached to a desired place.

Next, the structure and function of the tape cartridge 10 will be described with reference to FIGS. 3 and 4. Note that FIG.
Is a sectional view taken along line AA. This tape cartridge 1
0 can accommodate tapes of different widths with the same assembly configuration. In the embodiment, five types of tape cartridges in which the widths of the accommodated tapes are 6 mm, 9 mm, 12 mm, 18 mm, and 24 mm are provided. Figure 6
Of these 5 types of tape cartridges, the tape width is 6m
Ink ribbon core 22, ribbon winding core 2
4 is a cross-sectional view that is cut away at a position passing through the center of the platen 4 and the platen 12. Also, in FIG. 7, the tape width is 24 m as well.
It is sectional drawing which shows the thing of m. In order to simplify the drawing, the reference numerals of the respective members in FIG. 7 are omitted. Further, in FIGS. 6 and 7, a part of the print head 60 is drawn in the cross-sectional view of the tape cartridge in order to explain the attachment state to the tape writer 1.

The platen 12 used for printing is a hollow cylindrical member, and the five types of tapes T and ink ribbons R having different widths and the adhesion between the print head and the print head are made to be good, so that good quality printing is possible. Therefore, the platen rubber 14 is wound around the outer peripheral surface according to the tape width. In this embodiment, two types of platen rubber are used: a platen rubber having a width of 12 mm (see FIG. 6) for tapes of 6 mm, 9 mm, and 12 mm, and a platen rubber having a width of 18 mm (see FIG. 7) for tapes of 18 mm and 24 mm.

The outer circumferences of the upper and lower ends of the platen 12 are
The diameter of the platen 12 is slightly smaller than the shaft diameter of the platen 12, and the small diameter portion is rotatably loosely fitted into the fitting holes 16A and 18A formed in the top wall 16 and the bottom wall 18 of the tape cartridge 10. The platen 12 is rotatable. The fitting holes 16A and 18A have a substantially oval shape, as shown in FIGS. In this manner, the platen 12 erected on the tape cartridge 10 is detachable from a platen drive shaft, which will be described later, provided on the tape writer 1, and when the platen drive shaft is engaged with the platen drive shaft. The rotational drive force must be transferable. Therefore, on the inner peripheral surface of the hollow portion of the platen 12,
As shown in FIGS. 4 and 6, six engagement strips 12A are formed at equal intervals in the rotation axis direction.

In addition to the tape cartridge 10, a tape core 20, an ink ribbon core 22 and a ribbon winding core 24 are provided upright in order to compactly wind and store the long tape T and the ink ribbon R. Further, the tape cartridge 10 is provided with an entry hole 32 into which a print head described later enters. This entrance hole 3
The outer periphery 28 and the guide wall 34 are formed.

The tape core 20 is a large-diameter hollow-cylindrical reel, and is designed so that a long tape T can be wound up and stored thinly. Therefore, when the tape T located at the outermost circumference (reference numeral A in FIG. 3) is pulled out, the rotational angular velocity of the tape core 20 and the tape T located at the innermost circumference (reference numeral B in FIG. 3) are pulled out at the same speed. The rotational angular velocity of the tape core 20 is not so different from that of the tape core 20. Further, even if the tape T made of a material having a small curvature at the time of winding and storing is weak against bending stress, it can be stored without difficulty.

As shown in FIG. 5, the tape core 20 includes
A shaft hole 20B is formed at the center thereof and is rotatably fitted in a shaft body 18B provided upright from the bottom wall 18 of the tape cartridge 10. A circular thin film 20A is attached to the upper and lower ends of the tape core 20 in the axial direction, and the surface on the tape T side is an adhesive layer. This film 20A acts as a flange portion for the tape T,
Since the adhesive layer is provided on the surface of the tape T side,
The edge of the tape T is lightly attached to this film 20A.
Therefore, even if the tape T is pulled out by the rotation of the platen 12 and the tape core 20 is driven to rotate, the tape T does not come apart. A curved thin plate washer 23 is interposed between the lid body forming the ceiling wall 16 of the tape cartridge 10 and the film 20A on the upper surface of the tape core 20, and the tape core 20 is deformed by the deformation of the washer 23. Is pressed toward the bottom wall 18 to restrict free rotation of the tape core 20.

The tape T wound and stored on the tape core 20.
From the bottom wall 18 of the tape cartridge 10 to the platen 12 via the tape guide pins 26 provided upright,
It is pulled out to the outside from the tape ejection port 10A of the tape cartridge 10. The portion of the tape discharge port 10A has a predetermined length along the tape T transport direction and has a predetermined length.
B is formed. When the tape cartridge 10 is mounted in the tape cartridge mounting portion 50A, the print head 60 is located in the entry hole 32. In this state, the tape T is held between the print head 60 and the platen 12,
The tape T is transported by the rotation of the platen 12.

In order to wind and store the long tape T on the tape core 20, the end of the long tape T is fixed to the tape core 20 by a double-sided tape having a weak adhesive force. The tape cartridge 10 has a tape cartridge mounting portion 50.
When the tape T is attached to A and is used for printing and approaches the end, the tape T is peeled from the tape core 20 by the transport force of the platen 12 and the print head 60. The tape T is directly conveyed to the platen 12 and ejected from the tape ejection port 10A. As a result, especially tape T
Even if there is no mechanism or end mark for detecting the end of the tape, the user can recognize that the tape T is gone. Since the length of the ink ribbon R is longer than the total length of the tape T, the ink ribbon R still remains after the tape T is finished. Therefore, even if the printing is continued after the tape T is finished, the ink ribbon R is running and the destruction of the print head 60 due to heat accumulation is prevented.

Since the fitting holes 16A and 18A into which the upper and lower ends of the platen 12 are fitted have an elliptical shape as described above, the platen 12 is fitted in the tape cartridge 10 alone. It is movable along the long axis of the joint holes 16A, 18A. Therefore, the tape cartridge 10
When the tape T is pushed into the tape cartridge 10 from the outside of the plate, the movement of the tape T causes the platen 1 to move.
2 moves along the transport path of the tape T. Platen 1
When 2 moves, the platen rubber 14 of the platen 12 contacts the outer circumference of the tape guide pin 26, and the tape guide pin 2
The tape T is sandwiched between the tape 6 and the tape 6. As a result, the tape T becomes immovable and the tape T is not pushed into the tape cartridge 10.

As shown in FIGS. 6 and 7, the ink ribbon core 22 is composed of a hollow cylindrical member having a small diameter.
The outer circumferences of the upper and lower end portions are formed to have a slightly smaller diameter.
As shown in FIGS. 3 and 4, on the end surface of the lower end portion having the small diameter, six grooves are formed at equal intervals in the axial direction to form an engaging portion 22A. The small diameter portion on the lower end side is loosely fitted in a circular fitting hole portion 18C formed in the bottom wall 18 of the tape cartridge 10. The hollow portion at the upper end of the ink ribbon core 22 is the tape cartridge 1
It is loosely fitted in a cylindrical guide projection 16C provided on the top wall 16 of No. 0. Therefore, in this state, the ink ribbon core 22 is rotatably held by the ink ribbon R as it is pulled out.

As shown in FIGS. 3 and 4, the bottom wall 18 of the tape cartridge 10 is located near the bottom of the ink ribbon core 22 and the ribbon take-up core 24, which will be described later.
A thin substantially L-shaped engagement piece 18D is formed. The engagement piece 18D is formed by hollowing out a part (hatched portion X in FIG. 3) of the bottom wall 18 of the tape cartridge 10. Therefore, the tip of this engagement piece 18D is
Due to the elasticity of the members forming the above, the base end portion 18E that is continuous with the bottom wall 18 can be moved along the plane direction of the bottom wall 18 as a fulcrum. In the state where no force is applied to the engagement piece 18D, the movable end of the engagement piece 18D is located inside the outer periphery of the fitting hole portion 18C, so that the engagement hole portion 18C is free from play as described above. It engages with any of the six engaging portions 22A formed at the end of the fitted ink ribbon core 22 to prevent the ink ribbon core 22 from rotating.

The ink ribbon R, which is wound up and housed in the ink ribbon core 22, is guided by the ribbon guide roller 30 and overlaps with the above-mentioned tape T to reach the platen 12, and the print head further enters. Entry hole 3
The ribbon take-up core 24 is reached via the guide wall 34 formed on the peripheral surface of the second winding. When the tape cartridge 10 is in an unused state, that is, when only the starting end of the ink ribbon R is attached to the ribbon take-up core 24, the drawing state of the ink ribbon R is indicated by reference numeral C in FIG. R
The same state when all of the tapes are wound around the ribbon winding core 24 is shown by reference numeral D.

The ribbon take-up core 24 is composed of a hollow cylindrical member having substantially the same shape as the ink ribbon core 22, as shown in the figure. The outer circumferences of the upper and lower end portions are also formed to have a slightly smaller diameter, like the ink ribbon core 22. Six engaging portions 24A are provided at regular intervals on the end surface of the lower end portion having the small diameter. On the other hand, this ribbon winding core 24
6 engages with a ribbon take-up core drive shaft, which will be described later, provided in the tape writer 1 similarly to the platen 12 so that it can be rotationally driven. Therefore, the inner peripheral surface of the hollow portion has six engagement lines 24B in the axial direction. It is formed at intervals. The ribbon winding core 24 configured as described above is loosely fitted into the circular fitting holes 16G, 18G formed in the bottom wall 18 and the top wall 16 of the tape cartridge 10 at the small diameter portions formed at the upper and lower ends. It stands upright.

Also, in order to prevent the ribbon winding core 24 from rotating unexpectedly, the bottom wall 18 of the tape cartridge 10 has a thin substantially L shape whose end is located inside the outer periphery of the fitting hole 18G as described above. A letter-shaped engaging piece 18H is formed. That is, a part of the bottom wall 18 of the tape cartridge 10 (hatched portion Y in FIG. 3) is hollowed out, and the engaging piece 18
It is said to be H. With the cartridge 10 alone,
The end of the engaging piece 18H is engaged with any of the six engaging portions 24A formed at the end of the ribbon winding core 24, and the rotation of the ribbon winding core 24 is blocked. . The tips of the engaging pieces 18D and 18H are engaged with the engaging portions 22A and 24H.
The ink ribbon core 22 and the ribbon take-up core 24 are opposed to A at an angle, not at a right angle.
It is possible to rotate counterclockwise.

The engaging portion 2 of the ink ribbon core 22 as described above
Engagement of 2A and engagement piece 18D and ribbon winding core 24
The engagement between the engaging portion 24A and the engaging piece 18H is released by mounting the cartridge 10 on the cartridge mounting portion 50A, and the configuration thereof will be described later together with the structure of the cartridge mounting portion 50A. To do.

The ink ribbon R wound around the ribbon winding core 24 is a thermal transfer type ribbon, and a plurality of widths thereof are prepared according to the width of the tape T on the side to be printed. In this embodiment, as shown in FIG. 6, the tape width 6,
An ink ribbon having a width of 12 mm for 9, 12 mm, an ink ribbon having a width of 18 mm for a tape width of 18 mm (not shown), and an ink ribbon having a width of 24 mm having the same width for a tape width of 24 mm as shown in FIG. Three kinds of ink ribbons R are prepared in total.

When the ribbon width of the ink ribbon R is equal to the height of the tape cartridge 10 (see FIG. 7), the ink ribbon R is guided by the top wall 16 and the bottom wall 18, so that the ribbon is wound. Although the flange portion is not formed on the outer periphery of the core 24, in the case of the tape cartridge 10 having a narrow ribbon width, the tape ribbon 10 is provided on the outer periphery of the ribbon winding core 24 so that the ink ribbon R can be stably supplied to the platen 12. Is formed with a flange portion 24C conforming to the width of the ink ribbon R which is wound and stored.
To guide the ink ribbon R (see FIG. 6).

As described above, there are five types of tape cartridges 10 according to the present embodiment, depending on the width of the stored tape T. Since the printable area and the like differ depending on the width of the tape T, it is necessary to detect the type of the tape cartridge 10. In the tape cartridge 10 of the embodiment, as shown in FIG. 4, the bottom wall 18 of the cartridge is provided with three detection holes 18Ka, 18Kb, 18Kc so that the type of the tape cartridge 10 can be discriminated. That is, the detection holes 18Ka, 18Kb, 18Kc are formed to have different depths depending on the width of the tape T that is wound and stored.

Type of tape cartridge 10 and detection hole 1
The relationship with 8Ka, Kb, and Kc is shown in FIG. As shown, the three detection holes 18Ka, 18Kb, 18Kc of the tape cartridge 10 accommodating the tape width of 6 mm
Are all shallowly drilled. Further, in the tape cartridge 10 having a tape width of 9 mm, only one of the detection hole 18Ka, the detection hole 18Kb in the tape width 12mm, and the detection hole 18Kc in the tape width 18mm is deeply formed.

When the slide button 52 provided in front of the cartridge mounting portion 50A is slid to the right, the engagement between the main body cover 50K and the main body is released, and the main body cover 50K rotates around the cover hinge 54 at the rear of the main body as a fulcrum to open it. be able to. The slide button 52 is constantly biased to the left in the figure by the integrally provided spring arm 52A being locked by the locking portion on the main body side.

When the main body cover 50K is opened by operating the slide button 52, the print head 60 for printing on the tape T of the tape cartridge 10 can attach and detach the tape cartridge 10. About this operation
explain. As shown in FIG. 11, the print head 60 is rotatably mounted on a head rotation shaft 64 provided upright from a base board 61, and a head body 65 in which a plurality of heating elements are arranged is provided with an insulator 65a. Heat sink 6 to attach
5b, a frame 67 that supports the heat dissipation plate 65b by a connecting plate 67a, a coil spring 66 that biases the print head 60 toward an initial position, and a flexible cable 68 that is an electrical wiring to the head main body 65. With. In addition,
The frame 67 and the connecting plate 67a are connected by driving a pin 67b into the opening of the connecting plate 67a, and the heat dissipation plate 65b having the head main body 65 mounted thereon is rotatable about the pin 67b. . As a result, the print head 60
When pushing out to the platen 12 side, the head body 65
Will uniformly hit the tape T sandwiched between it and the platen 12.

The lower end portion of the frame 67 is largely extended to form a link plate 62. This link board 62
Are sewn between gear trains described later, and their ends are located near the boundary with the display unit 50D (see FIG. 10).
reference). A coil spring 69 is hooked on an end portion of the link plate 62 to connect the drive member 63 and the link plate 62. The drive member 63 has a substantially triangular shape, and the end 63a opposite to the end 63a to which the coil spring 69 is coupled has an end 63b as shown in FIG.
It is arranged at a position opposite to. An operation arm 50S extends downwardly and is formed at a position facing the end 63b of the body cover 50K, and the end 63b is pushed down by the operation of closing the body cover 50K.

That is, when the operation of closing the main body cover 50K is performed, the print head 60 is set to a printable position. On the other hand, when the operation of opening the main body cover 50K is performed, the operation of moving the print head 60 to the retracted position, which is required when the tape cartridge 10 is removed or attached, which is a normally executed action, is performed at the same time. Will be realized. The print head 60 once moved to the retracted position stays in that position by the coil spring 66 while the main body cover 50K is opened, and when the main body cover 50K is closed, the print head 60 moves to the platen 1.
Return to the position where 2 is pressed.

In this way, the bottom wall 18 of the tape cartridge 10 mounted in the cartridge mounting portion 50A is engaged with the engaging portions 22A and 24A of the ink ribbon core 22 and the ribbon winding core 24 in order to prevent them from rotating. It has already been described that the mating engagement pieces 18D and 18H are provided. The engagement pieces 18D, 18H are formed by hollowing out a part of the bottom wall 18 (FIGS. 3, 4, hatch portions X and Y),
As shown in FIG. 10, two conical abutment protrusions 70A and 70B are provided upright at the cartridge mounting portion 50A corresponding to the middle positions of the hatch portion X and the hatch portion Y. Therefore, when the tape cartridge 10 is mounted in the tape cartridge mounting portion 50A, the contact protrusions 70A, 70B are fitted in the hatch portions X, Y, and the engaging pieces 18D, 18H are attached to the ink ribbon core 22 and the ribbon take-up core. The engaging portions 22A and 24A of 24 are pushed and separated from each other. Thereby, the engagement pieces 18D, 1
The engagement by 8H is released, and the ink ribbon core 22 and the ribbon winding core 24 are in a rotatable state.

Next, a transmission mechanism for transmitting the rotation of the stepping motor 80 to the platen drive shaft 72 of the platen 12 will be described. As shown in FIG. 11, a first gear 81 is attached to a rotary shaft 80A of the stepping motor 80, and a clutch arm 80B is fitted to the rotary shaft 80A with a predetermined friction. . The clutch arm 80B includes a second gear 82 and a third gear 8
Together with 3, it constitutes a one-way clutch. That is,
When the stepping motor 80 rotates in the direction of arrow C in the figure, the clutch arm 80B rotates in the direction of arrow C together with the second gear 82 due to the friction between the rotating shaft 80A and the clutch arm 80B, and engages with the third gear 83. To do. As a result, the rotation of the stepping motor 80 is transmitted to the third gear 83. Regarding the function of the one-way clutch,
It will be described later.

The rotation of the third gear 83 is transmitted to the fifth gear 85 and the sixth gear 86 via the fourth gear 84 while further repeating gear down. Fifth gear 8
The rotating shaft of the winding No. 5 is coupled to the winding core drive shaft 74, and the ink ribbon R is wound up by the rotation of the stepping motor 80. In addition, the ribbon winding core 24 is actually
The rim 74A that drives the winding core drive shaft 74 is attached to the take-up core drive shaft 74 with a predetermined friction.
However, if the ribbon take-up core 24 becomes unrotatable due to reaching the end of the ink ribbon R or the like, it is assumed that the ribbon take-up core 24 slips with respect to the rotation of the take-up core drive shaft 74. ing.

The rotation of the sixth gear 86 is further transmitted to the seventh gear 87 to rotate the platen drive shaft 72. Below the platen drive shaft 72, a rim 72 </ b> A that fits into the irregularities on the inner peripheral surface of the platen 12 and drives it is provided. Therefore, when the stepping motor 80 rotates and its rotation is transmitted to the third gear 83 by the one-way clutch, finally the platen drive shaft 72 and the winding core drive shaft 74 rotate, and the platen 12 rotates. The tape T sandwiched between the platen rubber 14 provided on the outer periphery and the head main body 65 of the print head 60 is conveyed in accordance with printing, and the ink ribbon R is wound in synchronization with the conveyance of the tape T. Go on.

The platen 12 and the ribbon take-up core 24 are provided around the platen drive shaft 72 and the take-up core drive shaft 74.
The three protrusions 72B and 74B that engage with the engaging protrusions 12A and 24B formed on the hollow inner peripheral surface are formed at equal intervals. The platen drive shaft 72 and the winding core drive shaft 7
When 4 is rotationally driven at a predetermined rotation speed by the stepping motor 80, the tape T and the ink ribbon R are pulled out from the tape core 20 and the ink ribbon core 22 by a predetermined amount to be in a superposed state with each other, so that the platen rubber 14 and the print head 60 are separated from each other. Let it pass. At this time, the print head 60
If the amount of heat generated in dot units is controlled by energizing, the ink of the ink ribbon R can be thermally transferred to the tape T and printed on the tape T. After printing, tape cartridge 1
From 0, only the tape T on which printing has been completed is ejected, and the ink ribbon R used for printing is wound and collected on the ribbon winding core 24.

When the tape T is conveyed with printing in this way, the tape T is sent out from the tape discharge port 10A on the left side surface of the main body. The tape T is essentially cut by a cutting mechanism described later, but some users may try to pull out the tape T before cutting.
When the main body cover 50K is closed, the print head 60 presses the tape T against the platen rubber 14 of the platen 12. Therefore, if the tape T is forcibly pulled out, the platen drive shaft 72 also tries to rotate. However, since the gear is down and the holding torque of the stepping motor 80 is to some extent, the platen drive shaft 72 cannot be rotated by a normal drive mechanism. Naturally, the winding core drive shaft 74 also does not rotate. Therefore, when the tape T is pulled out, the ink ribbon R is pulled out together with the tape T. When the tape T is cut by using the cutting mechanism in this state, the ink ribbon R is also cut, so such a situation should not occur.

In this embodiment, the described clutch arm 8 is used.
This problem is avoided by the one-way clutch composed of 0B and the second and third gears 82 and 83.
That is, when pulling out the tape T, the platen drive shaft 72 rotates together with the platen 12. The rotation of the platen drive shaft 72 is transmitted through the gear train to the third gear 83.
Transmitted to and rotate it clockwise. At this time, the second gear 82 tries to rotate, but since the rotation shaft 80A of the stepping motor 80 does not rotate, the third gear 8 does not rotate.
The rotational force of 3 pushes away the clutch arm 80B that pivotally supports the second gear 82, and releases the engagement between the second gear 82 and the third gear 83. As a result, the third gear 83 to the seventh gear
The gear 87 is separated from the stepping motor 80, and the rotation of the platen drive shaft 72 accompanying the pulling out of the tape T causes the take-up core drive shaft 74 to rotate. Therefore, the ink ribbon R is also wound up when the tape T is pulled out, and is not pulled out together with the tape T. When the stepping motor 80 rotates, the rotation causes the clutch arm 80B to move to the third gear 83 side again, and the second gear 82 and the third gear 83 engage with each other. Such movement of the clutch arm 80B is temporarily restricted by the opening 80C provided in the base 61 and into which the tip of the clutch arm 80B is fitted.

By the above printing operation, the tape cartridge 1
The printed tape T ejected from 0 to the left is shown in FIG.
Using the cutting mechanism whose detailed structure is shown in FIG. 0 and FIG. 13, it can be easily cut as follows. Note that FIG. 13 is a C-C end view in FIG. 10. Cutter support shaft 9 protruding from the bottom of the cartridge mounting portion 50A
2 is a tape cutter 9 having a substantially "L" shape that is rotatable.
0 and the spring 94 are fitted, and the elastic force of the spring 94 maintains the tape cutter 90 in the state shown by the solid line in FIG. 13, that is, in the state in which the rotational force in the clockwise direction in the figure is applied. By this rotating force, the tape cutter 90
The left end portion 90A pushes up the cutter button 96 from its back surface. Left end 90A of tape cutter 90
Is formed in a bifurcated shape, and a pin 96A provided on the back surface of the cutter button 96 is inserted therein. Therefore,
When the cutter button 96 is pushed downward, the left end 90A of the tape cutter 90 is moved downward along with this.

Further, the right end portion 90B of the tape cutter 90
Is formed with a moving blade 98 for cutting the tape T, and is separated from the fixed blade 91 attached to the side surface of the cartridge mounting portion 50A at a constant angle. On the back surface of the right end portion 90B, the shoulder portion 93 of the tape retainer 93 is provided.
A is in contact (see FIG. 10). This tape restraint 93
As shown in FIG. 10, when the tape cutter 90 rotates and the moving blade 98 moves toward the fixed blade 91, the tape 95 is urged by the spring 95 toward the running path of the tape T. Move in the T direction. Since the fixed wall 97 is provided on the opposite side of the running path of the tape T, the tape retainer 93 includes the movable blade 98 and the fixed blade 9.
Prior to the cutting of the tape T by the method 1, the tape T is fixed to the fixing wall 97. The movement of the tape retainer 93 is detected by the detection switch 99. The detection switch 99 is for preventing printing while the tape T is being cut, as will be described later.

The cutting of the tape T is achieved by pushing down the cutter button 96 against the elastic force of the spring 94. Depress the cutter button 96 and press the tape cutter 9
When 0 is rotated counterclockwise in FIG. 13, the right end 90
The moving blade 98 formed on B also rotates in the same direction. As a result, the tape retainer 93 first restrains the tape T between itself and the fixed wall 97, and then the moving blade 98 gradually overlaps with the fixed blade 91 from its lower portion and passes through the print head 60 to the outside of the print head 60. The tape T located is cut.

Next, details of the input section 50C, the display section 50D, the printer section 50B and the like incorporated in the tape writer 1 will be described. For convenience of understanding the whole, the control circuit section 50F will be mainly described. The outline of the electrical configuration of each unit will be described. Immediately below the main body cover 50K, a control circuit unit 50F assembled on a printed circuit board is provided.
Is incorporated together with the printer unit 50B and the like. The overall electrical schematic configuration is shown in FIG. That is, the control circuit section 50F of the tape writer 1 includes ROM, RAM,
1-chip microcomputer (hereinafter referred to as CPU) 110 and mask R in which an input / output port is integrated
In addition to the OM 118, various circuits for interfacing the CPU 110 with the input section 50C, the display section 50D, the printer section 50B, etc. are incorporated. The CPU 110 is connected to the input unit 50C, the display unit 50D, or the like via an interface circuit or directly and controls these.

The input section 50C, as shown in FIG.
Equipped with 8 character input keys and 15 function keys, 63 keys in total. The character input key has a so-called full key structure based on the JIS arrangement, and is similar to a general word processor including a known shift key in order to suppress an increase in the number of operated keys. The function key is used to execute frequently used functions such as character input, editing, and printing with one touch, and enhances the functionality of the tape writer 1.

Each of these keys is assigned to an 8 × 8 matrix. That is, as seen from the CPU 110, as shown in FIG. 14, the 16 input ports PA1 to PA8 and PC1 to 8 are grouped as shown in the figure, and 63 kinds of keys of the input section 50C are arranged at each intersection. ing. The power switch 50J is provided independently of this matrix key and is connected to the non-maskable interrupt NMI of the CPU 110. C
When the power switch 50J is operated, the PU 110 activates an interrupt that cannot be masked, and performs each process of turning the power on or off.

The detection output from the opening / closing detection switch 55 for detecting the opening / closing of the body cover 50K is input to the port PB5, and the CPU 110 monitors the opened / closed state of the body cover 50K by interruption. The open / close detection switch 55 is
The movement of the main body cover 50K is detected by the movement of the opening / closing detection switch engagement protrusion 55L (see FIG. 12) provided at the end of the main body cover 50K. When the open state of the main body cover 50K is detected during the driving of the print head 60, a predetermined error display is displayed on the main display portion 50Da and the power supply to the printer portion 50B is turned off.

Ports PH, PM, PL of CPU 110
Is connected to the head rank determination unit 112. The head rank determination unit 112 is divided into several ranks based on the measurement result of the resistance value of the print head 60 having a large variation due to the manufacturing process, and the three jumper units 112A of the head rank determination unit 112 are classified according to the measurement results. , 112
B and 112C are set. Therefore, CPU11
0 reads the state of the head rank determination unit 112, and according to the input result, the drive time of the print head 60,
That is, the calorific value is corrected to prevent variations in print density.

Since the printing by the printer section 50B is performed by thermal transfer, the density of the printing varies not only with the energization time of the print head 60, which is a thermal head, but also with the outside air temperature and the driving voltage. These are detected by the temperature detection circuit 60A and the voltage detection circuit 60B. These circuits 60A and 60B are integrally incorporated in the print head 60, and the outputs thereof are the 2-channel analog-digital conversion input ports AD1 and AD2 of the CPU 110.
It is connected to the. The CPU 110 uses this port AD
The energization time of the print head 60 is corrected by converting the voltages of 1 and 2 into digital signals and reading them.

The determination switch 102 is connected to the ports PB1 to PB3 of the CPU 110. The determination switch 102 is provided in the lower right corner of the cartridge mounting portion 50A, as shown in FIG. The discriminating switch 102 is formed by integrally forming three cartridge discriminating switches 102A, 102B, 102C which respectively enter the three detection holes 18K formed in the tape cartridge 10. This cartridge discrimination switch 102
The protruding lengths of A, 102B, and 102C are designed according to the depth of the detection hole 18K formed in the tape cartridge 10 described above, and the cartridge determination switch 102 that has entered the shallow detection hole 18K has the detection hole 18K. The switch is turned on by abutting against and being pressed. Further, the cartridge determination switch 102 that has entered the deeply formed detection hole 18K is gently fitted into the detection hole 18K as it is, and the switch is turned off. Therefore, the three cartridge discrimination switches 10 of the discrimination switch 102
By detecting the states of 2A, 102B, and 102C, the type of the tape cartridge 10 currently mounted in the cartridge mounting unit 50A, that is, the tape cartridge 1
The width of the tape T stored in 0 can be determined. The information on the width of the tape T is used not only for controlling the size of characters to be printed but also for controlling the printer unit 50B described later.

A signal from the contact of the plug 50N is input to the port PB7 of the CPU 110. Plug 50
N is a DC power supply from the AC adapter 113 for jack 1
15 is accepted by being inserted, but at this time,
From the battery BT to the power supply unit 11 by the function of the break contact.
The power supply to 4 is cut off, and the power consumption of the battery BT is avoided. At the same time, the signal of the other contact provided on the plug 50N is input to the port PB7 of the CPU 110. Therefore, the CPU 110 can determine whether the main power source of the tape writer 1 is the AC adapter 113 or the battery BT by discriminating this signal and perform different control. In the present embodiment, the printing speed by the printer unit 50B is maximized when the power is supplied from the AC adapter 113, while the printing speed by the printer unit 50B is supplied when the power is supplied from the battery BT. Is reduced, the peak of the current flowing to the print head 60 is suppressed, and the power consumption of the battery BT is reduced.

The mask ROM 118 connected to the address bus and data bus of the CPU 110 is a Mincho type 16 × 1.
It is a 16-megabit mask ROM that stores a set of kana, kanji, and special characters of four types of fonts of 5, 24 × 24, 32 × 32, and 48 × 48. The 24-bit address bus AD, the 8-bit data bus DA, the chip select signal CS, and the output enable signal OE are the CPU 110.
Are connected to the ports PD0 to PD33. Since these signals are also directly connected to the external input / output connector 50Ea, the extension section 50E attached to the external input / output connector 50Ea can also be accessed like the mask ROM 118.

The expansion section 50E provided so as to be directly connectable to the control circuit section 50F serves as an insertion site for a ROM pack or RAM pack optionally supplied as an external storage element. By inserting the ROM pack or the RAM pack into this insertion port, the electrical connection with the external input / output connector 50Ea of the control circuit section 50F is completed, and the CPU 110
It becomes possible to exchange information with. With this configuration, a ROM pack that stores special characters and symbols for various drawings, maps, chemistry, and mathematics or language fonts other than Japanese, Gothic, Mincho, typeface, etc. is installed in the expansion section, It is possible to edit a desired character string. Similarly, a RAM pack, in which information can be written freely, is attached to the expansion part to store more information than the amount of information that can be stored in the RAM area inside the tape writer body, and to create a library of print character strings, etc. It can be used for exchanging information with the tape writer 1.

Mask ROM 118 or expansion section 50E
The dot data of the character read from the CPU 110
Together with the LCD controller 11 of the display control circuit 116
It is also input to 6A.

CPU 11 via display control circuit 116
The display unit 50D controlled by 0 is arranged below the main body cover 50K having a transparent corresponding portion, and the user visually recognizes it through the main body cover 50K. In the display unit 50D, two kinds of electrode patterns are formed on the liquid crystal panel, one of which is a dot matrix pattern of height 32 × width 96, and the other is this dot, as shown in FIG. It is a pattern of 28 pentagonal electrodes arranged so as to surround the area of the matrix. The area in which the electrodes of the dot matrix pattern are formed is the main display portion 50Da for displaying a print image.
The area in which the pentagonal electrode pattern is formed is referred to as an indicator portion 50Db.

The main display portion 50Da is used as a liquid crystal display panel capable of displaying 32 dots in height × 96 dots in width. In the present embodiment, each character used for inputting and editing characters is displayed on the main display unit using a character font of width 16 × height 15 dots, so 6 characters × 2
Lines can be displayed. Further, when displaying each character, the processing state of the tape writer 1 can be visually displayed by selectively using positive display, negative display, blinking display, etc. according to the editing state.

Further, since the main display portion 50Da is of the dot matrix type and the display contents thereof can be freely controlled, it is possible to display the layout of the current print image when a predetermined key input is made. When the layout display is instructed, as shown in FIG. 17, the 4 × 4 dots at the time of printing correspond to one dot on the main display portion, the tape width is displayed negatively, and a white character string is printed in it. Is displayed. At this time, the total length of the tape is displayed numerically as information that assists the print image. When the layout of the print image is too large to be displayed on the main display unit 50Da at one time, the entire print layout can be confirmed by scrolling up / down / left / right with the cursor keys.

The indicator portion 50Db is for displaying the function being executed by the tape writer 1 at the present stage, and is arranged around the main display portion 50Da. Each display body t obtained corresponding to the pentagonal electrode pattern in the indicator portion 50Db is
It is provided so as to correspond to characters representing the function printed around D. Character input mode status such as "Romaji input" or "Lower case input", style specification status such as "number of lines" or "box rule" for print editing, format specification status such as "equal allocation" or "justification", etc. When the state setting is executed or selected, the display body t at the portion of the character indicating the state is made visible.

The printer section 50B of the tape writer 1 is
A print head 60 and a stepping motor 80 are provided as mechanical components, and a printer controller 120 and a motor driver 122 for controlling the print head 60 and the stepping motor 80 are provided as electrical components. The print head 60 is a thermal head in which 96 heating points are arranged in a vertical line at a pitch of 1/180 inch, and the temperature detection circuit 60A for detecting the outside air temperature and the voltage detection for detecting the supply voltage described above. The circuit 60B is incorporated. Stepping motor 80
Is a known configuration in which the rotation angle is controlled by appropriately controlling the phases of the four-phase drive signals. Stepping motor 8
The tape feed amount for one step of 0 is designed to be 1/360 inch by the configuration of the gear train that is the reduction mechanism. In addition, a two-step rotation signal is output to the stepping motor 80 in synchronization with the dot-by-dot printing performed by the print head 60. As a result, the printer unit 50B
Printing at 180 dots / inch is performed not only in the width direction of the tape but also in the length direction thereof.

The above-described detection switch 99 is used for the printer controller 120 and the motor driver 122 as CP.
It is inserted in the common line connected from U110. Since this detection switch 99 detects the use state of the cutting mechanism, if the cutting mechanism is about to be used during printing, this detection switch 99 will be used.
And the operation of the printer unit 50B is immediately stopped. In this case, signals are continuously sent from the CPU 110 to the printer controller 120 and the motor driver 122. Therefore, if the use of the cutting mechanism is stopped, printing is continued.

In this embodiment, since the use of the cutting mechanism during printing interferes with the conveyance of the tape T, the printing operation (especially the tape feeding operation) is immediately stopped. Therefore, the detection switch 99 is directly connected to the motor driver 122. Although the power is forcibly cut off by inserting it into the common line of FIG. 3, it is possible to take the output of the detection switch 99 into the CPU 110 once and perform the same process as when the main body cover 50K is opened. Further, instead of the detection switch 99, the clutch arm 80 is moved by the movement of the moving blade 98 as a mechanical structure.
It is also possible to adopt a configuration in which B is pushed away and the rotation of the stepping motor 80 is not transmitted to the platen drive shaft 72.

In addition to the constituent members described above, the tape writer 1 has a power source 114 incorporated therein, and the battery BT is provided by the RCC method using an IC and a transformer.
Obtained stable 5V power supply for backup and logic circuit. The port PV is applied to the CPU 110 for controlling its voltage.

The tape writer 1 of this embodiment is similar to that shown in FIG.
As shown in FIG. 8, it has a margin function to secure a tape margin by a specified distance before and after the character string to be printed. This margin function includes a tape feed phase control signal for the front margin output before transmitting the 96-bit serial print data as described above, and a rear margin component output after transmitting all the serial print data. And the tape feed phase control signal. On the other hand, if the specified distance of such a margin is smaller than the distance between the printing position and the tape cutting position (less than 8 mm in this embodiment), the specified front margin cannot be realized. In this case, after the printing is completed, the tape T is sent out by the rear margin and the print head 6
This is handled by printing a line of cut mark PCM when 0 is at the tape position before the next print position by the designated front margin. If the ejected tape T is cut at the position of the cut mark PCM, it is possible to easily obtain a printing tape having a required front margin.

CPU 1 for controlling the peripheral circuits as described above
The internal ROM 10 stores various programs for executing the above-described operations. Also, its internal RA
Part of M is a system reserved area used when executing various programs stored in the internal ROM, and the other is a text area for editing characters and a file area for storing the contents of the text. It has been released as user use area.

The text area is assigned an area for accepting a fixed input of up to 125 characters, and stores style data and mode data for editing the character as well as the character code. Therefore, the stored contents are appropriately added or updated by the character input or the editing operation from the input unit.

The file area is 150 in the internal RAM.
0 character, 2000 in the optional RAM pack
The area where characters can be registered is allocated. Also, internal R
The file management program stored in the OM can store and manage 1 to 99 variable length files in this file area, and provides a basic operating environment such as file registration and call deletion.

Next, among the functions achieved by the control circuit section configured as described above, a particularly characteristic control of multi-line printing will be described. As shown in FIG. 19, the tape writer 1 of this embodiment uses a mask R with four font data of 16 × 16 to 48 × 48 dots as a basic font.
The fonts prepared in the OM 118 and not having the same number of dots among the fonts can be enlarged up to 2 times in the vertical direction and up to 4 times in the horizontal direction. Therefore, the maximum font is 9
There are 6 × 192 dots, and there are ten combinations of printable dot numbers, as shown in FIG.
Therefore, when editing the print character string over multiple lines,
In addition to the normal character input operation to input the character string to be printed on each line, it is necessary to specify the print font of the character string to be printed on each line.

Therefore, in the present embodiment, instead of the designation of the character font, the relative size relation of the character strings to be printed on each line (for example, in the case of printing three lines, the first line is large and the second line is (Large and small on the third line) are input by operating the keys on the input unit. Further, in order to make this key operation simpler, options are prepared in advance as illustrated in the case of three-line printing in FIG. 20 (in this embodiment, the same x3, small / small
5) (large, small / large / large, large / small / small, large / large / small) are selected to replace the input. This is realized as a simple setting mode, and a mode for setting the number of dots for each row is also prepared. In this case, the total number of dots in the vertical direction in a plurality of lines must be set so as not to exceed 96.

After completing all the input, the input unit 50C
When a key for instructing “print” is operated among the function keys of, the multi-line print processing program whose flowchart is shown in FIG. 21 is activated, and the CPU 110 performs the following processing. When the processing of the multi-line print processing program is started, the CPU 110 first reads the size relationship of the character strings in each row selected prior to this print command and the detection signal of the cartridge discrimination switch 102 (step 10).
0, 110), and check the information related to printing. And
The width of the currently loaded tape T is determined from the detection result of the cartridge determination switch 102, and the character of each line is referred to by referring to the font map stored in advance in the internal ROM based on the determination result and the size relation of each line character string. The font is determined (step 120).

As an example of this font map, a font map used for printing three lines is shown in FIG. As shown in the figure, the font map is created so that the print font used to print each line is uniquely determined when the size relationship of each line character string and the tape width are determined. Is 12 mm and the size relation of the character strings in each line is "small and large", the print font used to print each line is font S character on the first line, font P character on the second line, font P character on the third line. Is decided.
It should be noted that the same determination is made when the number of print lines is two, but the description is omitted here.

In this way, when the print font to be used for printing each line is determined, the print fonts corresponding to the character codes of the character string to be printed are sequentially read from the mask ROM 118 (step 130) and the dot pattern to be printed is set. Unfold (step 140) and set the dot pattern vertically 1.
The print control (step 150) is executed to cut out each column to create 96-bit serial data and transfer it to the printer unit as described above.

In the tape cartridge 10 constructed as described above, when the tape cartridge 20 is in a single state in which it is not attached to the tape writer 1, the tape core 20 is attached to the bottom wall 18 by the washer 23.
The tape core 20 is rotated by the tape T
Never loosens. Moreover, since the adhesive layer is provided on the tape T side surface of the film 20A attached to the upper and lower ends of the tape core 20, there is a concern that the edge of the tape T will adhere to the film 20A and the tape T will come loose. Nor.

Further, in this embodiment, the platen 12 has the oblong fitting holes 16A provided in the top wall 16 and the bottom wall 18,
Since the tape T is loosely fitted in the tape cartridge 18A, when the outside of the tape cartridge 10 tries to push the tape T into the inside of the tape cartridge 10, the platen 12 causes the tape guide pin 2 to move.
It moves in six directions and holds the tape T between it and the tape guide pin 26. Therefore, further movement of the tape T is prevented and the tape T does not enter the inside of the tape cartridge 10. Further, since the guide portion 10B is provided in the vicinity of the tape discharge port 10A of the tape cartridge 10, the tip of the tape T is at the tape discharge port 10A.
Even if it slightly enters the inside of A, there is no problem in carrying out the tape T by the print head 60 and the platen 12.

Further, in this embodiment, when the tape cutter 90 is used during printing, the detection switch 99 detects the use of the tape cutter 90, and immediately the rotation of the stepping motor 80 and the head body 6 of the print head 60 are detected.
The power supply to 5 is stopped. Therefore, the tape T is not jammed in the tape cartridge 10 by using the tape cutter 90 while the tape T is being conveyed during printing. As a result, the usability of the tape writer 1 is improved and the labor of maintenance is reduced.

In the above embodiment, the rotation of the tape core 20 is prevented only by pressing the tape core 20 against the bottom wall 18 with the washer 23, but various configurations can be made to prevent the rotation of the tape core 20. For example, as shown in FIG. 22, the film 20 attached to the upper end of the tape core 20.
A part of A is cut and raised, and the cut and raised portion 20C engages with the projection 16D provided on the inner surface of the ceiling wall 16 which is the lid body in only one rotation direction.
It is possible to prevent the tape core 20 from rotating in the direction in which the tape loosens.

In this embodiment, the tape T is the tape core 20.
An example in which the present invention is applied to the tape cartridge 10 that is wound around and stored in the tape cartridge 1 and the tape writer 1 that executes printing on the tape T is shown, but the present invention is not limited to such an embodiment. Needless to say, the present invention can be embodied in various forms, such as a configuration of the tape cartridge 10 in which the tape T is folded and stored, a configuration in which a rotation preventing engagement portion is provided on the bottom surface of the tape core 20, and the like.

As described above with reference to the embodiments, the print sheet cartridge of the present invention has an excellent effect that the problem that the tape T gets into the cartridge case can be solved. Therefore, when detaching and using the print sheet cartridge for printing equipment,
The storage and handling of the print sheet cartridge becomes easy. Such an advantage is particularly great in a printing device that requires the replacement of a print sheet cartridge.

Further, in the printing apparatus of the present invention, if the mechanism for cutting the print sheet discharged from the print sheet cartridge is to be operated during the transport of the print sheet, the drive of the print platen drive shaft is interrupted to stop the print sheet. Since the discharge of the sheet is interrupted, it is possible to solve the problem that the print sheet is clogged due to the accidental use of the cutting mechanism. Therefore, it is possible to improve the usability of the printing device, which is premised on the cutting of the printing sheet, and reduce the labor such as the maintenance of the printing device.
