When a character string input as necessary is converted to a kana-kanji character or the like and a predetermined key is operated to instruct printing, printing is performed on the tape T supplied by the tape cartridge 10 by the printer unit 50B of the thermal transfer system. . The printed tape T is discharged from a tape discharge port 10A provided on the left side surface of the tape writer 1. The tape T used in the present embodiment has a printing surface processed in order to improve the placement of the ink by thermal transfer, and a peelable peeling tape is adhered to the adhesive back surface. Therefore, by cutting the printed tape with a built-in cutter and peeling off the release 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 mainly with reference to FIGS. FIG.
Is a sectional view taken along the line A-A. This tape cartridge 1
No. 0 is capable of storing tapes of different widths by a similar assembling configuration. In the embodiment, five types of tape cartridges are provided in which the width of the stored tape is 6 mm, 9 mm, 12 mm, 18 mm, and 24 mm. FIG.
The tape width is 6m among the five types of tape cartridges.
m, and FIG. 7 shows a tape width of 24 mm.
It is sectional drawing which drew the thing. In order to simplify the drawing, the reference numerals of the respective members in FIG. 7 are omitted. 6 and 7, a part of the print head is illustrated in a sectional view of the tape cartridge in order to explain a state of attachment to the tape writer 1.

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

The outer peripheries of the upper and lower ends of the platen 12 are:
The tapen portion is formed to have a slightly smaller diameter than the shaft diameter of the platen 12, and the small diameter portion is rotatably loosely fitted into fitting holes 16A and 18A formed in the top wall 16 and the bottom wall 18 of the tape cartridge 10. , Platen 12 is rotatable. The fitting holes 16A and 18A have a substantially oval shape as shown in FIG. The platen 12 erected on the tape cartridge 10 in this manner is detachable from a platen drive shaft, which will be described later, provided on the tape writer 1, and when engaged with the platen drive shaft, the platen 12 The rotational driving force must be able to be transmitted. Therefore, the inner peripheral surface of the hollow portion of the platen 12
As shown in FIG. 6 and FIG.
2A are formed at equal intervals.

In addition, the tape cartridge 10 is provided with a tape core 20, an ink ribbon core 22, and a ribbon take-up core 24 for taking up and storing the long tape T and the ink ribbon R in a compact manner. Further, the tape cartridge 10 is provided with an entrance hole 32 into which a print head described later enters. This entry hole 3
The outer periphery 28 and the guide wall 34 are formed.

The tape core 20 is a large-diameter hollow cylindrical reel, which is designed to take up and store a long tape T thinly. Therefore, the rotational angular velocity of the tape core 20 at the time of pulling out the tape T located at the outermost periphery (reference numeral a in FIG. 3) and the tape T at the same speed when the tape T located at the innermost periphery (reference numeral b in FIG. The configuration is not so different from the rotational angular velocity of the tape core 20. Further, even when the tape T of a material having a small curvature at the time of winding storage and weak in bending stress is used, 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 into a shaft body 18B which is erected from the bottom wall 18 of the tape cartridge 10. A circular thin film 20A is attached to the upper and lower ends in the axial direction of the tape core 20, and the surface on the tape T side is an adhesive layer. This film 20A functions as a flange portion for the tape T,
Since the adhesive layer is provided on the surface on the tape T side,
The edge of the tape T is lightly attached to the 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 is not separated. A curved thin plate-shaped washer 23 is interposed between the lid constituting the top 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 in the direction of the bottom wall 18 to restrict the free rotation of the tape core 20.

The tape is guided to the tape outlet 10A of the tape cartridge 10.

As shown in FIGS. 6 and 7, the ink ribbon core 22 is formed of a small-diameter hollow cylindrical member.
The outer peripheries of the upper and lower ends are slightly smaller in diameter.
As shown in FIGS. 3 and 4, six grooves are formed at equal intervals in the axial direction on the end surface of the small-diameter lower end portion to form an engaging portion 22A. The small diameter portion on the lower end side is loosely fitted in a circular fitting hole 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 to a cylindrical guide projection 16C protruding from the top wall 16 of the 0. Accordingly, in this state, the ink ribbon core 22 is rotatably held as the ink ribbon R is pulled out.

As shown in FIGS. 3 and 4, on the bottom wall 18 of the tape cartridge 10, near the bottom of the ink ribbon core 22 and a ribbon winding core 24 described later,
A thin substantially L-shaped engagement piece 18D is formed. The engagement piece 18D is formed by hollowing out a part (a hatched portion X in FIG. 3) of the bottom wall 18 of the tape cartridge 10. Therefore, the tip of the engagement piece 18D is
Is movable along the plane direction of the bottom wall 18 with the base end portion 18E connected to the bottom wall 18 as a fulcrum due to the elasticity of the member constituting. When no force is applied to the engaging piece 18D, the movable end thereof is located inside the outer periphery of the fitting hole 18C, so that the movable end is loosely fitted to the fitting hole 18C as described above. Engage with any of the six engagement portions 22A formed at the end of the fitted ink ribbon core 22,
The rotation of the ink ribbon core 22 is prevented.

The ink ribbon R supplied by being wound up and stored in the ink ribbon core 22 is guided by the ribbon guide roller 30 to be superposed with the tape T described above, reaches the platen 12, and further enters the print head. Entry hole 3

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 character C in FIG. R
The same state when all of the above are wound on the ribbon winding core 24 is indicated by reference numeral d.

The ribbon take-up core 24 is formed of a hollow cylindrical member having substantially the same shape as the ink ribbon core 22, as shown in the figure. The outer peripheries of the upper and lower ends are formed to have a slightly smaller diameter, similarly to the ink ribbon core 22. Six engagement portions 24A are recessed at regular intervals on the end surface of the small diameter lower end. On the other hand, this ribbon winding core 24
Is engaged with a ribbon take-up core drive shaft, which will be described later, provided on the tape writer 1 similarly to the platen 12 so as to be rotatable. It is formed at intervals. The small-diameter portions formed at the upper and lower ends of the ribbon winding core 24 thus configured are 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. It is installed to be rotatable.

In order to prevent accidental rotation of the ribbon take-up core 24, the bottom wall 18 of the tape cartridge 10 has a thin L-shaped portion whose inner end is located inside the outer periphery of the fitting hole 18G as described above. A letter-shaped engagement piece 18H is formed. That is, a portion of the bottom wall 18 of the tape cartridge 10 (hatched portion Y in FIG. 3) is hollowed out, and the engagement piece 18

Hereinafter, each of the mechanical components of the tape writer 1 will be sequentially described. FIG. 10 is a plan view of the configuration of the tape cartridge mounting section 50A, and FIG.
1 is a platen 12 driven by the power of the stepping motor 80.
FIG. 4 is a perspective view illustrating a main configuration of a driving mechanism 50P that drives the like.
It is.

The cartridge mounting portion 50A is arranged on the left rear side of the main body of the tape writer 1, and is formed as a mounting space conforming to the shape of the tape cartridge 10 as shown in FIG. As shown in FIG. 11, a shaft and a print head 60 that engage with the hollow portions of the ribbon take-up core 24 and the platen 12 are provided upright in the mounting space. Further, the rotation of the stepping motor 80 is controlled by the platen 12 below the tape cartridge mounting portion 50A.
The drive mechanism 50P for transmitting the drive mechanism 50P is provided, but is separated by the case of the tape cartridge mounting portion 50A.

The mounting or replacement of the tape cartridge 10 in the cartridge mounting section 50A is performed by
This is done with 0K open. 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 with the cover hinge 54 at the rear portion of the main body as a fulcrum and opens it. be able to. Note that the slide button 52 is constantly receiving a leftward biasing force in the figure by locking a spring arm 52A provided integrally with a 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 performing printing on the tape T of the tape cartridge 10 can attach and detach the tape cartridge 10. About this behavior,
explain. As shown in FIG. 11, the print head 60 is rotatably mounted on a head rotating shaft 64 erected from a base board 61, and a head main body 65 in which a plurality of heating elements are arranged via an insulator 65a. Heat sink 6 to be attached
5b, a frame 67 supporting the heat radiating plate 65b by the connecting plate 67a, a coil spring 66 for urging the print head 60 toward the initial position, and a flexible cable 68 as an electric wiring to the head main body 65. And In addition,
The connection between the frame 67 and the connecting plate 67a is made by driving a pin 67b into an opening of the connecting plate 67a, and the radiating plate 65b to which the head body 65 is mounted is rotatable about the pin 67b. . As a result, the print head 60
Is pushed out to the platen 12 side, the head body 65
Will uniformly hit the tape T sandwiched between the platen 12.

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

FIG. 12 is a sectional view taken along the line BB of FIG. 10 schematically showing this movement. As shown, as the main body cover 50K is pushed down, the operation arm 50S pushes down the end 63b of the drive member 63,
At the same time, the link plate 62 is
Rotates rightward in FIG. This movement of the link plate 62 causes the print head 60 to rotate against the biasing force of the coil spring 66. As a result, the print head 60 moves from the retracted position to a print position facing the platen 12 of the mounted tape cartridge 10. That is, when the operation of closing the main body cover 50K is performed, the print head 60 is set to a printable position. Conversely, 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 necessary when the tape cartridge 10 is removed or mounted, which is the next normally performed operation, is performed simultaneously. Will be realized. The print head 60 once moved to the retracted position remains at the position while the main body cover 50K is opened by the coil spring 66, and when the main body cover 50K is closed, the print head 60
2 returns to the position where it is pressed.

The bottom wall 18 of the tape cartridge 10 mounted on the cartridge mounting portion 50A in this manner is engaged with the engaging portions 22A, 24A for preventing the rotation of the ink ribbon core 22 and the ribbon winding core 24. As described above, the engaging 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 and hatch portions X and Y).
As shown in FIG. 10, two wedge-shaped abutment projections 70A and 70B are provided upright at a portion of the cartridge mounting portion 50A corresponding to a middle position between the hatch portion X and the hatch portion Y. Therefore, when the tape cartridge 10 is mounted on the tape cartridge mounting portion 50A, the contact projections 70A and 70B are fitted into the hatch portions X and Y, and the engaging pieces 18D and 18H are connected to the ink ribbon core 22 and the ribbon winding core. 24 are pressed apart in a direction away from the engagement portions 22A, 24A. Thereby, the engagement pieces 18D, 1
The engagement by 8H is released, and the ink ribbon core 22 and the ribbon take-up core 24 become rotatable.

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 rotating shaft 80A of a stepping motor 80, and a clutch arm 80B is fitted to the rotating shaft 80A with a predetermined friction. . The clutch arm 80B includes a second gear 82, a third gear 8

When the stepping motor 80 rotates in the direction of arrow C shown in the figure, the clutch arm 80B rotates in the direction of arrow C together with the second gear 82 due to friction between the rotating shaft 80A and the clutch arm 80B, and engages with the third gear 83. I do. As a result, the rotation of the stepping motor 80 is transmitted to the third gear 83. About 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 repeating gear down. Fifth gear 8
Reference numeral 5 has its rotating shaft connected to the take-up core drive shaft 74, and takes up the ink ribbon R by the rotation of the stepping motor 80. Note that the ribbon winding core 24 is actually
Is mounted with a predetermined friction on the take-up core drive shaft 74, and in a normal state, the rim 74A is driven by the stepping motor 80.
However, if the ribbon take-up core 24 cannot rotate due to the end of the ink ribbon R or the like, it is determined 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. A rim 72 </ b> A is provided below the platen drive shaft 72 to engage with and drive the unevenness of the inner peripheral surface of the platen 12. Therefore, when the stepping motor 80 rotates and its rotation is transmitted to the third gear 83 by the one-way clutch, the platen drive shaft 72 and the take-up core drive shaft 74 eventually rotate, and the platen 12 The tape T sandwiched between the platen rubber 14 provided on the outer periphery and the head body 65 of the print head 60 is transported in accordance with printing, and the ink ribbon R is wound up in synchronization with the transport of the tape T. Go on.

The platen 12 and the ribbon take-up core 24
The protrusions 72B and 74B that engage with the engagement ridges 12A and 24B formed on the inner peripheral surface of the hollow are formed at equal intervals. The platen drive shaft 72 and the take-up core drive shaft 7
4 is 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 superposed on each other, and the gap between the platen rubber 14 and the print head 60 is formed. Let it pass. At this time, the print head 60
, And the amount of heat generated in units of dots is controlled to thermally transfer the ink of the ink ribbon R to the tape T and print on the tape T. After printing, tape cartridge 1
From 0, only the tape T on which printing is completed is discharged, and the ink ribbon R used for printing is wound up and collected by the ribbon winding core 24.

When the tape T is conveyed together with the printing as described above, the tape T is sent out from the tape discharge port 10A on the left side of the main body. The tape T is originally cut by a cutting mechanism described later, but some users may try to pull out the tape T before cutting.
In a state where the main body cover 50K is closed, the print head 60 presses the tape T against the platen rubber 14 of the platen 12, so that when the tape T is forcibly pulled out, the platen drive shaft 72 also tries to rotate. However, since the gear is down and there is a certain amount of holding torque of the stepping motor 80, the platen drive shaft 72 cannot be rotated by a normal drive mechanism. Naturally, the winding core drive shaft 74 does not rotate either. 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 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 clutch arm 8 described
This problem is avoided by a one-way clutch constituted by OB and the second and third gears 82 and 83.
That is, when trying to pull 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 to a third gear 83 via a gear train.
And rotate it clockwise. At this time, the second gear 82 tries to rotate, but the rotation shaft 80A of the stepping motor 80 does not rotate.
The rotation force of 3 pushes back the clutch arm 80B that 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 cut off from the stepping motor 80, and the take-up core drive shaft 74 is also rotated by the rotation of the platen drive shaft 72 accompanying withdrawal of the tape T. Accordingly, the ink ribbon R is also wound up with the pulling out of the tape T, so that the ink ribbon R is not drawn out together with the tape T. When the stepping motor 80 rotates, the clutch arm 80B moves to the third gear 83 again by the rotation, and the second gear 82 and the third gear 83 are engaged. The movement of the clutch arm 80B is temporarily restricted by the opening 80C provided on the base 61 and fitted with the tip of the clutch arm 80B.

By the above printing operation, the tape cartridge 1
The printed tape T discharged from 0 to the left is shown in FIG.
Using the cutting mechanism whose detailed configuration is shown in FIG. 0 and FIG. 13, the cutting can be easily performed as follows. FIG. 13 is a sectional view taken along the line CC in FIG. Cutter support shaft 9 protruding from the bottom of cartridge mounting portion 50A
2 is a rotatable substantially "L" shaped tape cutter 9;
The tape cutter 90 is maintained in a state shown by a solid line in FIG. 13, that is, a state in which a clockwise rotating force is applied by the elastic force of the spring 94. This rotational force causes the tape cutter 90
90A pushes the cutter button 96 upward from its back surface. Left end 90A of tape cutter 90
Is formed in a forked shape, into which a pin 96A provided on the back surface of the cutter button 96 is inserted. Therefore,
When the cutter button 96 is pressed down, the left end 90A of the tape cutter 90 is moved downward accordingly.

The right end 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 fixed angle. The shoulder 93 of the tape holder 93 is provided on the back of the right end 90B.
A is in contact (see FIG. 10). This tape holder 93
As shown in FIG. 10, the tape 95 is urged in the direction of the running path of the tape T by a spring 95. When the tape cutter 90 rotates and the movable blade 98 moves in the direction of the fixed blade 91, the tape It moves in the direction of the travel path of T. Since the fixed wall 97 is provided on the opposite side of the running path of the tape T, the tape holder 93 is provided with the moving blade 98 and the fixed blade 9.
Prior to cutting of the tape T by 1, the tape T is fixed to the fixing wall 97. The movement of the tape holder 93 is detected by the detection switch 99. As will be described later, this detection switch 99 is for preventing printing from being performed while the tape T is being cut.

The cutting of the tape T is achieved by pushing down the cutter button 96 against the elastic force of the spring 94. Press down the cutter button 96 and press the tape cutter 9
0 is rotated counterclockwise in FIG.
The moving blade 98 formed in B also rotates in the same direction. As a result, first, the tape holder 93 holds down the tape T between the fixed wall 97 and the moving blade 98. Then, the moving blade 98 gradually overlaps with the fixed blade 91 from the lower part thereof, passes through the print head 60, and moves to the outside of the print head 60. The tape T located is cut.

Next, the details of the input unit 50C, the display unit 50D, the printer unit 50B and the like incorporated in the tape writer 1 will be described. For the sake of easy understanding of the whole, the control circuit unit 50F will be described first. An outline of the electrical configuration of each unit to be performed 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. FIG. 14 shows the overall electrical schematic configuration. That is, the control circuit unit 50F of the tape writer 1 includes ROM, RAM,
A one-chip microcomputer (hereinafter referred to as CPU) 110 and a 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 unit 50C, the display unit 50D, the printer unit 50B, and the like are incorporated. The CPU 110 is connected to the input unit 50C, the display unit 50D, and the like via the interface circuit or directly, and controls them.

As shown in FIG. 15, the input unit 50C
Eight character input keys and 15 function keys are provided for a total of 63 keys. The character input keys have a so-called full key configuration based on the JIS arrangement, and are the same as general word processors, such as having a well-known shift key in order to suppress an increase in the number of keys to be operated. The function keys enable frequently-used functions such as character input, editing, and printing to be executed with a single touch, and enhance the functionality of the tape writer 1.

Each of these keys is assigned to an 8 × 8 matrix. That is, as viewed from the CPU 110, as shown in FIG. 14, the 16 input ports PA1 to PA8 and the PC1 to PC8 are grouped as shown in the drawing, and 63 types of keys of the input unit 50C are arranged at their intersections. ing. The power switch 50J is provided independently of the 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 various processes such as power-on or power-off.

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

Ports PH, PM, PL of CPU 110
Are connected to the head rank determination unit 112. The head rank determination unit 112 divides the resistance value of the print head 60 having a large variation due to the manufacturing process into several ranks based on the measurement result, and three jumper units 112A of the head rank determination unit 112 according to the measurement result. , 112
B, 112C. Therefore, the CPU 11
0 reads the state of the head rank determining unit 112, and determines the driving time of the print head 60 according to the input result;
That is, the calorific value is corrected to prevent variations in print density.

Since printing by the printer unit 50B is performed by thermal transfer, the density of printing varies not only with the energizing time of the print head 60, which is a thermal head, but also with the outside air temperature and drive voltage. These are detected by the temperature detection circuit 60A and the voltage detection circuit 60B. These circuits 60A and 60B are integrated into the print head 60, and output from the CPU 110 is a two-channel analog-to-digital conversion input port AD1, AD2.
It is connected to the. The CPU 110 uses this port AD
The power supply time of the print head 60 is corrected by converting the voltages 1 and 2 into digital signals and reading them.

The discrimination switch 102 is connected to the ports PB1 to PB3 of the CPU 110. The discrimination switch 102 is provided at the lower right corner of the cartridge mounting section 50A as shown in FIG. The discrimination switch 102 is formed by integrally forming three cartridge discrimination switches 102A, 102B, and 102C that enter the three detection holes 18K formed in the tape cartridge 10, respectively. This cartridge discriminating switch 102
The protrusion lengths of A, 102B, and 102C are designed in accordance with the depth of the detection hole 18K formed in the tape cartridge 10 described above. And the switch is turned on. Further, the cartridge discriminating switch 102 that has entered the deeply formed detection hole 18K is loosely fitted into the detection hole 18K as it is, and the switch is turned off. Therefore, the three cartridge discrimination switches 10 of this discrimination switch 102
By detecting the states of the tape cartridges 2A, 102B, and 102C, the type of the tape cartridge 10 currently mounted in the cartridge mounting section 50A, that is, the tape cartridge 1
It is possible to determine the width of the tape T stored in 0. 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 the DC power from the AC adapter 113 to the jack 1
15 is accepted by being inserted, but at this time,
By the function of the break contact, the power supply 11
4, the power supply to the battery 4 is cut off, and the power consumption of the battery BT is avoided. At the same time, a signal of another contact provided on the plug 50N is input to the port PB7 of the CPU 110. Therefore, by determining this signal, the CPU 110 can determine whether the main power supply of the tape writer 1 is based on the AC adapter 113 or the battery BT, and perform different control. In this embodiment, when power is supplied from the AC adapter 113, the printing speed by the printer unit 50B is maximized, while when power is supplied from the battery BT, the printing speed by the printer unit 50B is , The peak of the current flowing through 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 16 × 1
It is a 16-megabit mask ROM that stores a set of four types of kana, kanji, and special characters 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
Ports PD0 to PD33. These signals are also directly connected to the external input / output connector 50Ea, so that the extension unit 50E attached to the external input / output connector 50Ea can access the same as the mask ROM 118.

The extension section 50E provided so as to be directly connectable to the control circuit section 50F serves as an insertion portion of a ROM pack or a RAM pack which is optionally supplied as an external storage element. By inserting a ROM pack or a RAM pack into this insertion slot, electrical connection with the external input / output connector 50Ea of the control circuit unit 50F is completed, and the CPU 110
Information can be transmitted and received. With this configuration, a ROM pack that stores special characters and symbols for various drafting, maps, chemistry, and mathematics or character fonts other than Japanese, such as Gothic, Mincho, and print fonts, is attached to the extension unit. A desired character string can be edited. Similarly, a RAM pack in which information can be freely written is attached to the expansion unit, and information larger than the amount of information that can be stored is stored in the RAM area inside the tape writer body, and a library of print character strings is created. Can be used for exchanging information with the tape writer 1.

The mask ROM 118 or the extension unit 50E
The dot data of the character read from the
And the LCD controller 11 of the display control circuit 116.
6A is also input.

The CPU 11 via the display control circuit 116
The display unit 50D controlled by 0 is disposed under the main body cover 50K whose corresponding part is transparent, and the user can visually recognize the display unit 50D through the main body cover 50K. In the display unit 50D, two types of electrode patterns are formed on a liquid crystal panel. As shown in FIG. 16, one of them is a dot matrix pattern having a height of 32 × 96 and a second is a dot matrix pattern. 28 are pentagonal electrode patterns arranged so as to surround the area of the matrix. The area where the electrodes of the dot matrix pattern are formed is a main display section 50Da for displaying a print image.
And the area where the pentagonal electrode pattern is formed is referred to as the indicator section 50Db.

The main display section 50Da is used as a liquid crystal display panel capable of displaying 32 dots high by 96 dots wide. In the present embodiment, since each character at the time of character input and editing is displayed on the main display using a character font having a width of 16 and a height of 15 dots, 6 characters × 2
Line display is possible. In displaying each character, the processing state of the tape writer 1 can be visually displayed by using a positive display, a negative display, a blinking display, or the like according to the editing state.

Further, since the main display section 50Da is in a dot matrix format and its display contents can be freely controlled, it is also possible to display the current print image layout when a predetermined key input is made. When the layout display is instructed, as shown in FIG. 17, 4 × 4 dots at the time of printing correspond to one dot of the main display portion, the tape width is displayed in a negative manner, and a print character string is outlined in white. Is displayed. At this time, the total length of the tape is numerically displayed as information to assist the print image. If the layout of the print image is too large to be displayed on the main display unit 50Da at a time, the entire print layout can be confirmed by scrolling left and right using the cursor keys.

The indicator section 50Db is for displaying the function being executed by the tape writer 1 at the present stage, and is arranged around the main display section 50Da. Each display body t obtained corresponding to the pentagonal electrode pattern in the indicator section 50Db is
It is provided corresponding to a character representing a function printed around D. Character input mode status such as "Romaji input" and "lower case input", style specification status such as "number of lines" and "enclosing rule" to be printed and edited, and format specification status such as "equal layout" and "adjustment" When the state setting is executed or selected, the display body t at the position of the character indicating the state is made visible.

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

The detection switch 99 described above is connected to the printer controller 120 and the motor driver 122 by the CP.
It is interposed in the common line connected from U110. Since the detection switch 99 detects the use state of the cutting mechanism, when the cutting mechanism is about to be used during printing, the detection switch 99 is used.
Is activated, and the operation of the printer unit 50B is immediately stopped. In this case, since signals from the CPU 110 to the printer controller 120 and the motor driver 122 continue to be sent, if the use of the cutting mechanism is stopped, printing is continued.

In this embodiment, since the use of the cutting mechanism during printing hinders the transport of the tape T, the printing operation (especially the tape feeding operation) is immediately stopped. , The power is forcibly cut off, but the output of the detection switch 99 is once taken into the CPU 110 and the same processing as when the main body cover 50K is opened may be performed. In addition, instead of the detection switch 99, as a mechanical configuration, the movement of the movable blade 98 causes the clutch arm 80 to move.
B may be pushed to prevent the rotation of the stepping motor 80 from being transmitted to the platen drive shaft 72.

In addition to the components described above, the tape writer 1 has a power supply unit 114 incorporated therein, and the battery BT is formed by the RCC method using an IC and a transformer.
As a result, a stable 5 V power supply for backup and logic circuits is obtained. A port PV is assigned to the CPU 110 for controlling its voltage.

Note that the tape writer 1 of this embodiment is the same as that shown in FIG.
As shown in FIG. 8, there is a margin function for securing a tape margin by a specified distance before and after a character string to be printed. The margin function includes a tape feed phase control signal for the front margin outputted before transmitting the 96-bit serial print data as described above, and a rear margin output signal outputted after transmitting all the serial print data. And a tape feed phase control signal. On the other hand, if the designated distance of such a margin is smaller than the separation distance between the printing position and the tape cutting position (less than 8 mm in this embodiment), the designated front margin cannot be realized. In this case, after the printing is completed, the tape T is fed by the amount of the trailing margin, and the print head 6
This is done by printing a single cut mark PCM when 0 is at the tape position before the next print position by the specified front margin. If the discharged tape T is cut at the position of the cut mark PCM, it is possible to easily obtain a print tape having a necessary amount of front margin.

CPU 1 for controlling peripheral circuits as described above
Various programs for executing the above-described operations are stored in the internal ROM 10. Also, its internal RA
M is partly used as a system reserved area used when executing various programs stored in the internal ROM, and is used as a text area for editing characters and a file area for storing the contents of the text. It has been released as a space used by users.

The text area is assigned an area for accepting a confirmed input of up to 125 characters, and stores, in addition to a character code, style data and mode data for editing the character. Therefore, the stored contents are appropriately added or updated by a character input or an editing operation from the input unit. This text area prepared on the internal RAM of the CPU 110 is also called a print data buffer.

The file area has 150 files in the internal RAM.
0 characters, 2000 for optional RAM pack
An area where characters can be registered is allocated. Also, the internal R
By the file management program stored in the OM, 1 to 99 variable length files can be stored and managed in this file area, and a basic operation environment such as file registration and call deletion is provided.

<Description of Software> Next, the processing executed by the tape writer 1 of this embodiment will be described. FIG.
9 is a flowchart showing a main part of a processing routine executed by the tape writer 1. In this tape writer 1,
There are various operation modes, and when a specific function key or the like in the input unit 50C is operated, the mode shifts to various modes such as a line number designation mode and a layout display mode, which will be described later. When the mode is not specified and the key corresponding to the character is operated, character data to be finally printed is input.

When this processing routine is started, the processing mode is determined first (step S200). If a specific mode is not specified, it is determined that the mode is the character input mode and print data is input (step S200). S21
0). The input of the print data is realized by directly inputting a key for alphanumeric characters and the like, and for a kana kanji character, converting a kana input from the input unit 50C into a kana-kanji character and converting the result into a print data buffer.

The print data input from the input unit 50C is normally added to the end of the print data buffer. However, the insertion point may be placed in the middle of the already input character string by operating the cursor keys. It is possible. In the present embodiment, the addition of the print data is inserted into the existing input data. However, the print data may be overwritten.

Since the print data buffer has a maximum of 125 characters, if more characters than this are input from the input unit 50C, an overflow process is performed (step S220). This is a process in which, when input data is added at the end of a character string, when kana-kanji conversion is completed and the character string to be input is determined, a portion exceeding 125 characters is cut off. Yes, if input data is inserted in the middle of a character string, a process of deleting more than 125 characters from the end of the character string stored in the print data buffer when insertion is performed is there.

After performing such overflow processing,
A process of displaying the determined character string on the display unit 50D is performed (step S230). The display unit 50D has a maximum of 2 rows x
Six characters are displayed, and a head of line indicating the number of lines is added at the beginning of each line. The line head mark also occupies one character in the print data buffer, and a flag (2 bits) indicating that it is a line head mark in 16 bits per character, the number of lines (up to four lines, two bits are sufficient), typeface (3 bits for 7 typefaces), font designation (5 bits including division of internal font and external font), designation of line spacing and character spacing (4 bits), etc. This line head mark is usually shown in a form in which the number indicating the line is inverted in black and white, and its display will be described later. After performing the display processing, the process exits to “NEXT” and temporarily ends the processing routine.

Next, the mode for designating the number of lines and the like will be described. When the number of lines designation mode is designated, various designation processes such as designation of the number of print lines and designation of automatic / manual are performed (step S240). Specified objects include typefaces (highlighted, italic, underlined, sack, inverted, etc.), character spacing (narrow, normal, wide), line spacing (left), font in internal font or external ROM font And so on. The process of making these designations is performed in such a manner that a desired designation is selected from options prepared in advance. That is, since the maximum number of printing lines is four in this embodiment, the number of printing lines is selected from “1”, “2”, “3”, and “4”. Select one of When you operate the cursor key or space key, these options are highlighted in order,
Confirm by operating the key.

In this embodiment, if the print data has already been input over a plurality of lines, it is not possible to specify a smaller number of lines. If print data does not exist even when a plurality of lines are specified, it is possible to specify a small number of print lines. For example, as shown in FIG. 20A, even when three-line printing has already been specified, if only one line has print data, one to four lines can be specified. On the other hand, as shown in FIG. 20B, when print data exists in two lines, only designation of two to four lines is possible. Of these designations, in the tape writer 1 of this embodiment, the designation of the number of print lines and the vertical / horizontal writing is called “style”, and the other designations (character spacing, etc.) are called “mode”. I'm different.

If printing of a plurality of lines is selected, a process for designating a combination of fonts is performed next (step S250). The combination of fonts is specified as follows. As shown in FIG. 21, the tape writer 1 of the present embodiment uses four font data from 16 × 16 to 48 × 48 dots as basic fonts in the mask ROM 11.
The fonts that do not have the number of overlapping dots in each font can be expanded up to twice in height and up to four times in width. Therefore, the maximum font is 96 × 19
2 dots, and the combination of printable dot numbers
As shown in FIG. 21, there are ten types. Therefore,
When editing the print character string over multiple lines, in addition to the normal character input operation of inputting 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 this embodiment, in place of the character font designation, the relative magnitude relation of the character strings to be printed on each line (for example, in the case of three-line printing, the first line is large and the second line is large) (Large on the third line) is input by key operation of the input unit. Further, in order to further simplify the key operation, options are prepared in advance as shown in FIG. 22 to exemplify a case of three-line printing (in the present embodiment, the same × 3, small, small,
Large, small / large / large, large / small / small, large / large / small), and selecting this replaces the input. Note that this is realized as a simple setting mode, and a mode for setting the number of dots for each line is also provided. In this case, the total number of dots in the vertical direction in a plurality of rows must be set so as not to exceed 96. The font size may be specified by the layout display shown in FIG.

In the character display after these designations are completed (step S230), as shown in FIG. 24, if two or more lines are designated, a display such as "1" or "2" is displayed at the beginning of the line. Done. Also, if “manual” is specified, all line head marks are displayed in reverse video,
If "automatic" is designated, the line head mark is displayed as a normal display with a frame for the second and subsequent lines, for which no print data has been input. When a character is input (steps S210 and S220) and a character is input in the second and subsequent lines, the head of the line is changed to an inverted display state (see the lowermost column in FIG. 24).

In step S240, the number of lines newly specified may be different from the number of lines previously specified. In this embodiment, these cases are handled as follows. When the designation of the number of print lines increases, FIG.
As shown in (A), a line where print data does not exist at the end is added. When the number of print lines is reduced, as described above, there is a line in which print data does not exist, and this line is deleted. When there are a plurality of lines where no print data exists, as shown in FIG. 25B, the lines are deleted from the lower lines where no print data exists. In addition, when adding a new line, it should be added to the top line,
Changes such as deleting rows from the upper row can be made as appropriate.

Next, the layout display will be described.
When the layout display mode is designated, first, the output of the cartridge discrimination switch 102 is read (step S260). By this processing, the CPU 110
Can determine the type of the tape cartridge 10 currently mounted on the tape writer 1, in particular, the width of the printable tape T. After determining the width of the tape T, a layout display is performed based on the currently specified number of print lines, font designation, and the like (step S270).
An example of the layout display has already been shown in FIG. Furthermore,
FIG. 8 shows an example of a layout display in a case where the tape cartridge 10 is not mounted, and in a case where the tape width of the tape cartridge 10 in which the currently specified style and mode (designation of the number of lines and font) are mounted does not match. 26.

As shown in FIG. 17, when the width of the tape T is normal, the tape T is displayed in black and characters are displayed in white, whereas when the tape T is not mounted, Indicates that the tape T is not displayed and characters are displayed in black. That is, when the tape T is not mounted, since the display of characters is opposite to the normal state, it can be seen at a glance that the tape T is not mounted. If a frame line is specified, this is also displayed.

On the other hand, in the case where the width of the tape T is insufficient, the protruding portion (the portion where the tape width is insufficient) is displayed in an inverted manner. In these cases, a separate warning is displayed,
You can also report by voice. When the layout display is completed, the display returns to the normal character display state (step S230).

Next, the print mode will be described. When the print mode is designated, first, the detection signal of the cartridge discrimination switch 102 is read (step S280), and then the width of the currently mounted tape T is judged from the detection result of the cartridge discrimination switch 102, and the judgment result Based on the size relationship between the character strings of each line and the size of each line character string, a process of expanding the dot pattern of each line is performed with reference to a font map stored in advance in the internal ROM (step S290).
The dot pattern of each line is developed as follows.

First, the font of each line is determined. As illustrated in FIGS. 21 and 22, the print font of each line is uniquely determined when the size relationship of each line character string and the tape width are determined. For example, when the tape width is 12 mm and the size of the character strings in each line is “large and small”, the printing font used for printing each line is a font S character in the first line, a font P character in the second line, and a font P in the third line. The font is determined to be a P character.
In the case where the number of print lines is two, the determination is made in the same manner, but the description is omitted here.

When the print font to be used for printing each line is determined in this way, the print font corresponding to the character code of the character string to be printed is sequentially read from the mask ROM 118 and developed into a dot pattern to be printed. The above is the dot pattern development processing (step S290).
When the dot pattern development is completed, a printing process is executed next (step S300). The printing process is performed by cutting out the developed dot pattern for each vertical column, creating 96-bit serial data, and transferring the data to the printer unit.

The printing of the character string stored in the print data buffer is performed in this manner, but the printing mode differs depending on the setting of automatic / manual. "Manual" is a mode in which the print data stored in the print data buffer is printed as specified by the number of print lines. In practice, it is often performed to designate printing of a plurality of lines, for example, to designate printing of two lines, input printing data over two lines, and then delete the printing data of the second line. It is. In this case, since the user has deleted the print data on the second line, it is easy to think that printing is already performed on one line. Therefore, when "automatic" is designated, as shown in FIG. 27A, if there is no print data in the second line, it is regarded as one line and a dot pattern is formed using a font with a large number of dots. Expand and print. On the other hand,
If print data exists in both lines, it is regarded as two-line printing, and printing is performed using a font with a smaller number of dots as shown in FIG. 27B. On the other hand, when "manual" is designated, as shown in FIG. 27C, printing is performed in two lines even if there is no print data in the second line. In the above description, it is assumed that two-line printing is specified, but the same applies to a case where three-line printing, four-line printing, and the like are specified.

Next, the recording / calling mode will be described. As described above, the tape writer 1 of this embodiment converts print data input from the input unit 50C into an internal RA.
Up to 1500 characters in M and up to 200 in extension 50E
Up to 0 characters can be recorded as a file. Therefore, when the recording / calling mode is specified, it is first determined whether the file is accessible. (Step S310). Here, “accessible” means that when recording is selected, the internal RAM or the extension unit 50E
Is a case where there is free space for storing a new file, and when a call is selected, this means a case where a recorded file exists. If the access is not possible, the character is displayed without performing anything (step S230).
Return to On the other hand, if access is possible, either the process of recording the character string currently in the print data buffer as a file or the process of calling the already recorded character string into the print data buffer is performed according to the instruction. Perform (Step S320).

When a character string existing in the print data buffer is recorded as a file, character attribute information (mode and style) is also stored. That is, character spacing, line spacing, typeface (emphasized characters, sack characters, underlined, italic characters, etc.)
Such information is also recorded together. At the time of calling, the print data is also called to the print data buffer along with such information. At this time, when print data input from the input unit 50C exists in the print data buffer, the called print data is added to the end of the existing print data. Therefore, when the attributes of the two print data are different, a process of adding a division mark is performed (step S330).

As shown in FIG. 28, the division mark is provided by attaching a right-pointing triangular mark immediately after the head of line mark. The division mark is a mark having information such as a typeface and a space between characters like the head of line mark. That is, the print data called in a form linked to the print data existing in the print data buffer is set as the line head mark, the current attribute information setting is set, and recorded as a file by the division mark inserted immediately after that. The attribute at the time of being set will be set. As a result, if these print data are printed, the input print data is printed according to the specification, while the called print data is printed according to the specification at the time of recording. Moreover, if a new paragraph is generated after the called print data and the print data is input, there is an advantage that the attribute of the print data is not affected by the attribute of the called print data. It is often experienced that after calling, it is desired to match the attribute of the called print data with the attribute of the print data input from the input unit 50C, but in this case, it is only necessary to delete the division mark. good.

The handling and operation of the tape writer 1 of this embodiment has been described with reference to typical use modes. The tape writer 1 has various other use modes,
Their description is omitted.

According to the tape writer 1 of the embodiment configured as described above, by the processing of the above-described processing program, the tape writer 1 is used to print each line from the magnitude relation of each line character string specified before printing and the tape width. The print font to be used is determined, and a desired print output can be obtained for the tapes T of various widths without requiring complicated management and complicated control.

That is, the user of the tape writer 1 draws an image of the printing tape as a result of printing the character string in his mind, and executes various operations in order to make this a reality. There are almost no cases where you want to specify the font. This is because it is enough to determine vaguely the magnitude relation of the character strings printed on each line. Therefore, in the conventional printing apparatus, the user has to specify the size of the printing characters and the like each time by referring to a printing sample or the like. On the other hand, the tape writer 1 according to the present embodiment enables the input of the magnitude relation of each line character string according to the vague image of the user, and automatically determines the print font for realizing this. doing. Therefore, complicated work such as managing the width of the tape T to be printed is omitted, and desired printing can be performed without any calculation of the number of fonts or complicated operation for obtaining a desired printing result. The applied printing tape can be easily obtained.

The printing apparatus according to the present invention is not limited to the above-described embodiment, but may be embodied in various forms. For example, in the above embodiment, as an attribute defining means for defining an attribute of a character to be printed on each line, the magnitude relation of each line character string is described as an example. May be defined selectively or in combination. According to a printing apparatus having such an attribute defining means, it is possible to instruct a print image having a higher degree of freedom as it is,
A desired printing tape excellent in design can be easily obtained.

Further, if "automatic" is designated, for example, two-line printing is designated, and the printing result can be made different depending on whether or not the data of the second line exists. The tape writer 1 automatically avoids the mistake of the user who easily thinks that the second line itself has been deleted by deleting the print data of the second line. As a result, the usability of the tape writer 1 is significantly improved. Since the designation of "automatic" or the designation of "manual" has been made, it can be distinguished at a glance by the display form of the line head mark.

In addition, according to the present embodiment, when the tape T is not mounted, or when the tape cartridge 10 having a tape width insufficient for the designated style mode is mounted, the layout is changed. You can know this at a glance by the display. In the present embodiment, these problems are displayed in an easy-to-understand manner, and it is assumed that the printing process cannot be performed.However, when the printing process is selected, a configuration in which the printing is automatically reduced and a warning is issued so as not to protrude. Various measures are possible, such as a configuration in which options that do not protrude are displayed.

Further, according to the tape writer 1 of the present embodiment, the print data can be recorded as a file together with its attributes, and can be connected to the print data buffer and called. In addition, at this time, if the attributes of the two are different, a division mark is added to the boundary between the two, so that this can be clearly displayed. In addition, the operability is extremely good, for example, the same style and mode can be achieved by simply deleting the division mark.

[0107]

As described above with reference to the embodiments, the first printing apparatus of the present invention designates the number of printing lines to be printed on a printing tape, and specifies the number of printing lines to be printed on each line.
By specifying the relative magnitude relation, it is printed on each line.
The character size to be used depends on the type of cartridge installed.
Can be determined . For example, the number of dots of print data is determined from the number of print lines and the tape width,
It is possible to determine that it is impossible and to automatically take measures such as reducing printing or changing attributes. Thus, Printout apparatus of the present invention, the number of printing lines and the specified type of the tape cartridge and the attributes defined in the print data, to determine the printing conditions, an excellent that can take various operation effects To play. Such thinking, without any the conventional printer, "predetermined operation" in the Printout apparatus of the present invention is not limited any way as described in example, it is the far-extensive.

Further, according to the second printing apparatus of the present invention,
After specifying the number of print lines, the print state on the print tape is determined based on the presence or absence of print data in each of the specified lines. Therefore, even if the number of print lines is specified, if there is a line where print data does not exist, it is possible to cope with that line and print it out. Absent. Therefore, wasteful consumption of the tape due to a printing error can be prevented.

Further, according to the third printing apparatus of the present invention,
The input print data can be stored in the storage means together with the print mode, and can be read out without erasing another print data that has already been input. The display of both print data is different. Therefore, the user does not need to set the printing mode such as the number of printing lines and the font style each time the print data is saved or read, and it is not necessary for the user to recognize that the printing modes are different. It has an excellent effect that it can be easily known.
