Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a recording material cassette for a thermal transfer printer.

(Background of the Invention) An ink sheet made of a very thin film made of resin or paper coated with a colored layer containing a heat-melting or heat-sublimating coloring material is placed in close contact with an image-receiving paper and heated by a thermal head to produce ink. 2. Description of the Related Art So-called thermal transfer printers, which form images by transferring coloring materials on a sheet onto image-receiving paper, are already known and widely used.

However, in conventional thermal transfer printers, two types of consumables, an ink sheet and an image receiving paper, are loaded into the printer equipment separately, and if either one is used up, printing becomes impossible. Managing and supplying these materials was complicated. In addition, especially in the case of a line-type thermal transfer printer that uses a line-type thermal head, it is necessary to handle an extremely thin ink sheet with a width almost equal to the width of the image receiving paper, which requires even more complicated operations. There was a drawback.

(Object of the Invention) An object of the present invention is to improve these drawbacks and provide a compact recording material cassette for a thermal transfer printer that is easy to manage and supply.

(Summary of the Invention) In order to achieve this object, in the present invention, a part for storing cut paper-like image receiving paper and a part for storing a roll-like ink sheet are integrated, and the ink sheet is rolled up. We propose a new recording material cassette for thermal transfer printers, in which a roller is configured to be removably attached.

(Description of Embodiments) Hereinafter, embodiments of a thermal transfer color printer using a line printer type thermal head will be described.

------- Part 1 to End of Page The cassette 1 of the embodiment mainly consists of the following 1, a main body part 1a 2, an ink sheet 4 3, and an ink sheet winding part 1b.

FIG. 1 is a perspective view of the top of the recording material cassette 1 of this embodiment, and FIG. 2 is a perspective view of the bottom.

The cassette I is composed of a cassette main body 1a and an ink sheet winding section 1b that houses an ink sheet winding roller 14, and the winding section 1b is detachably connected to the main body 1a as described later. .

In FIGS. 1 and 2, the cassette 1 is the "first cassette" in the present invention.
It is in a ``combined state'' which corresponds to the ``state of''.

The operation of changing from the combined state to the "second state" in the present invention is called "separation", and the separated states, including the "second state J", are called "separated states". In other words,
The cassette 1 can be separated and combined.

FIG. 3 is a partially exploded perspective view of the cassette 1 in a separated state.

■9 Main body part 1a The main body part 1a is protected by a thin rectangular parallelepiped-shaped housing 6, and as shown in FIGS. The stored image receiving paper supply chamber 3 and the unused ink cartridge 1 rolled into a roll paper
・It is separated by a partition wall into an ink sheet supply chamber 5 which houses the ink sheet 4.

The receiving paper supply chamber 3 corresponds to the "first part" in the present invention, and the ink sheet supply chamber 5 corresponds to the "second part".

As shown in FIG. 7, in the receiving paper supply chamber 3 there is a receiving paper mounting plate 8 which is urged upward by a compression spring 7, and constantly presses the receiving paper 2 against the upper part of the housing 6.

As shown in FIG. 1, a receiving paper feeding roller hole 9a and a receiving paper discharge port 9b are opened in the upper part of the housing 6, and a receiving paper feeding roller 70 shown in FIG. 18 is opened in the feeding roller hole 9a. comes down and touches the receiving paper 2,
As this roller rotates, the image-receiving paper 2 is sent out one by one from the image-receiving paper outlet 9b.

Further, in the upper part of the housing 6, a window 10 is provided for inputting detection light and detecting reflected light from the image receiving paper 2 in order to detect whether or not the image receiving paper 2 is present. The image receiving paper 2 is generally white and has a high reflectance, so if the mounting plate 8 is made to have a low reflectance or a low reflectance mark is provided at the position where the detection light hits, it will be easy to detect when the image receiving paper 2 is used up. Since the amount of reflected light decreases, if this change in the amount of light is detected by the second photodetector (OP-2) shown in FIG. 13, the presence or absence of the image receiving paper 2 can be detected. Initially, the amount of cut paper-like image receiving paper 2 and the amount of roll paper-like ink sheet 4 was 1:1.
Therefore, in order to know when to replace the cassette 1, it is possible to detect the absence of the image-receiving paper 2 or the absence of the ink sheet 4. Since it is like a cut paper, there is a risk of double feeding (a phenomenon in which two or more sheets are sent out at the same time), and in that case, even if the ink sheet 4 remains, the receiving paper 2 will be used up and the cassette 1 will have to be replaced. Therefore, it is preferable to provide the detection device on the image receiving paper 2 side.

On the other hand, at the bottom of the housing 6, as shown in FIG.
A hole 11a for locking the image receiving paper portion is formed on the left side of the middle, a hole 11b for locking the ink sheet supply roller on the right side near the back surface, and a notch hole 11C for separating the cassette on both left and right sides of the rear end.

As shown in FIG. 3, guide grooves 12 for fitting the housing 15 of the ink sheet winding section 1b are provided on both left and right side surfaces of the housing 6, and the projecting piece 15a of the housing 15 is inserted into the guide groove 12. Fits horizontally.

As shown in FIG. 5, an ink sheet supply chamber 5 is provided on the back side of the housing 6, and an ink sheet supply roller 13 is rotatably mounted in the supply chamber 5. The ink sheet 4 is wound into a roll paper.

A rubber ring 13a is provided at one end of the ink sheet supply roller.

As shown in FIG. 3, the rear surface of the housing 6 is completely open, and as shown in FIG. 4, the other end of the ink sheet 4 is wound around the ink sheet winding roller 14 of the ink sheet winding section 1b. It is.

Therefore, the ink sheet 4 can be wound up by rotating the roller 14.

2. Ink sheet 4 FIG. 4 is a perspective view of the ink sheet 4. The ink sheet is in the form of a roll, one end of which is wound around an ink sheet supply roller 13, and the other end of which is wound around an ink sheet take-up roller 14.
It is wound up.

The ink sheet 4 is a support sheet with a thickness of 4 to 20 μm, for example.
It consists of a polyethylene terephthalate sheet and a colored layer (ink layer) coated on top of it.

The colored layer is divided into regions each having a shape and size corresponding to the image receiving paper 2, and each region has a different color tone of yellow (Y), magenta (M), and cyan (C) in order. These Y, M, and C areas are repeated in order. As is already known, the composition of the Ingi layer is, for example, heat sublimable coloring materials (sublimable dyes) of colors corresponding to each tone.
and a vehicle (resin component).

3. Ink sheet winding section 1b As shown in FIG.
Projecting pieces 15a extend toward the front on both the left and right sides of 5. This protruding piece 15a fits into the guide groove 12 of the image receiving paper section housing 6.

As shown in FIG. 5, a roller 14 is rotatably attached to the storage chamber of the ink sheet take-up roller 14, and a gear 14a having a larger outer diameter than the roller 14 is fixed to the right end of the roller 14. ing.

As shown in FIG. 1, an ink sheet winding gear hole 16 is opened in the upper cloth of the housing 15, and the gear 14a can be seen from there. As shown in FIG.
An external drive gear 111 meshes with the roller 42 to rotate the roller 14.

4. Mechanism for combining and separating the cassette 1 itself As described above, the cassette 1 can be separated and combined into the main body portion 1a and the ink sheet winding portion 1b. This mechanism will be explained.

FIG. 6 is a cross-sectional view obtained by cutting the cassette 1 of FIG. 5 along a plane perpendicular to the plane of paper passing through χl , a cassette coupling lever +7b whose one end is pivotally supported by a lever shaft 17a is provided. This lever 17b is biased downward by a substantially square-shaped lever return spring 17C.
is the housing 15 by the bar 2S axis 17d at the vertex of ■.
attached to the side wall of.

On the other hand, the cassette coupling lever 17b has a notch 17e, and the lever hooks provided here near the bottom surface of both sides of the housing 6 of the main body portion 1a are locked when the bin 18 is engaged, and the cassette 1 cannot be separated.

However, if the cassette coupling lever 17b rotates upward about the lever shaft 17a and the lever hook is disengaged from the bin 18, the lock is released and the cassette can be separated.

Next, the configuration of a thermal transfer color printer using the recording material cassette 1 will be explained.

FIG. 8 shows the external appearance of the printer with the cassette 1 installed. On the front, there is a cassette loading slot 24 in the middle on the left side, and a printed receiving paper (hereinafter also referred to as "print") on top of the cassette loading slot 24.
The discharge ports 25 are open, and a print switch 116 and a power switch 115 are provided on the right side, and a display section 117 is attached above them.

The cassette 1 is inserted through the mounting port 24 as shown in FIG. 8, and the completed printer is discharged from the discharge port 25.

FIG. 9 shows an outline of the mechanical arrangement inside the printer. If it is roughly divided into an upper part and a lower part like a fence, the upper part and the lower part can be opened and closed with the bin 11B provided at the upper part as the center of rotation. Note that the bearing of the bottle provided at the bottom is not shown. Furthermore, when divided by function, it has the following nine block configurations.

5. A cassette drive mechanism section 6 that guides and drives the cassette during automatic loading, unloading, and ejection after it is installed in the printer; a lock mechanism section 7 of the cassette main body 1a; a lock mechanism section 8 of the ink sheet supply roller 13; , a holding mechanism section 9 of the ink notebook winding section 1b, an ink sheet winding mechanism section 10, an image receiving paper feeding mechanism section 11 that feeds the image receiving paper 2 to the platen mechanism section, a platen mechanism section 12, and an elevating mechanism section 13 of the thermal head 36. , receiver paper 2
V to the platen 76: J conduction and ejection mechanism section In the lower part of Fig. 9, there are 5, 6, 7 and 10 in the lower right part, 12 in the center part, 8 and 9 in the upper left part, and 13 is located from the bottom right to the center, and 11 is located at the top left.

Each mechanical section will be explained in detail below.

5. Cassette Drive Mechanism FIG. 10 is a perspective view showing an outline of the cassette drive mechanism and the ink sort winding section holding mechanism.

The cassette drive mechanism section has left and right cassette guides 31.3.
2, a driving power source and a driving mechanism located between them. A first limit switch LSwl is placed at the tip (inner side) of the left cassette guide 32, and a second limit switch LS2 is placed near the middle. To detect.

FIG. 11 is a conceptual diagram showing the driving force transmission mechanism of the entire printer. To explain with reference to Figures 10 and 11,
A gear 71 fixed to the output shaft of the second motor 29 meshes with a gear 72. Rotating shaft 73 to which gear 72 is fixed
is coupled coaxially with the input shaft of the first tfff clutch 35, and the gear 26 is connected to the output shaft of the first electromagnetic clutch 35.
is attached. 12 on the plate 88 shown in FIG.
As shown in the figure, a shaft 88a and a shaft 88b are fixed.

A gear 27 that meshes with the gear 26 is rotatably mounted on a shaft 88a, as shown in FIG. 12, and a gear 28 that meshes with the gear 27 is rotatably mounted on a shaft 88b. . In other words, the axis sea,
Gears 27 and 28 rotate freely relative to s8b.

As shown in FIG. 12, a cassette moving rubber roller 30 is integrally connected to the gear 28 using a shaft 88b as a common axis, and the roller 30 rotates together with the gear 28.

Therefore, when the second motor 29 rotates as shown in FIG.
6-gear 27-gear 28-rubber roller 30.

On the other hand, as shown in FIG.
A relatively rotatable shaft 89 is fitted into the inner diameter portion of a, and one end of the shaft 8S is fixed to the right side casing 7) guide 31. Therefore, the plate 88 is vertically rotatable about the shaft 89.

As shown in FIG. 12, the plate 88 is urged upward by a torsion spring 91 with the shaft 89 as the center of rotation.
It is possible to rotate until it comes into contact with the plate rotation limiting bin SO shown in FIG. As a result, the rubber roller 30 can revolve around the shaft 89 and is always urged upward.

Therefore, as shown in FIG.
When the cassette 1 is inserted into the cassette 2 and the tip of the cassette 1 contacts the rubber roller 30, and the operator advances the cassette 1 further into the cassette 1, the rubber roller 30 is pushed down by the cassette 1 with the shaft 89 as the center of rotation. , the rubber roller 30 is in contact with the bottom of the cassette 1.

Furthermore, the rubber roller 30 is brought into strong contact with the bottom of the cassette 1 by the torsion spring 91.

Therefore, as the second motor 2S rotates, the rubber roller 3
If the cassette 0 rotates forward, the cassette 1 will move toward the back, and if the cassette 1 rotates in the reverse direction, it will return to the front.

6. Locking Mechanism of Main Body 1a When the ink sheet winding section 1b rotates the roller 14 and winds up the ink sheet 4, the main body 1a needs to be fixed. This is the main body locking mechanism.

As shown in Fig. 10, there is a first solenoid 33 with a return spring inside the left side center guide 32 at the far end.When this solenoid 33 is energized and turned on, it resists the biasing force of the return spring. plunger 34 is retracted into the solenoid. When turned off, the plunger 34 protrudes from inside the solenoid due to the biasing force of the return spring.

Since the head of the plunger 34 is hemispherical, even if the cassette 1 or the main body 1a approaches and comes into contact with the plunger 34, the plunger 34 will sneak under the bottom of the cassette 1 or the main body 1a. Cassette 1 or main body 1
There is no problem with the movement of a. When the position of the hole 11a of the housing 6 coincides with the position of the head of the plunger 34, the plunger 34 fits into the protruding hole 11a by the biasing force of the return spring. As a result, cassette 1 or main body 1
Stop the movement of a and lock it at the same time.

Since there is little time for the plunger 34 to be drawn into the solenoid throughout the entire process, the solenoid 3 with no return λ
3 is used to reduce power consumption by reducing the amount of time it is turned on.

7. Mouth of ink sheet supply roller 13 - Rib structure As will be explained later, it is necessary to lock the ink sheet supply roller 13 in order to take up slack in the ink sheet during printing.

As shown in Fig. 1O, a second solenoid with a return spring is installed at the inner side of the right side door guide 31, so that in the OFF state, the plunger 87 is pulled downward by the biasing force of the return spring. In the ON state, the plunger 87 protrudes upward against the biasing force of the return bus. Then, the upper part of the protruding plunger 87 enters the hole 11b provided at the bottom of the main body 1a of the cassette 1, and strongly presses the rubber ring 13a provided at the end of the ink sheet supply roller.
rotation is locked.

8 Holding mechanism section 19 of ink sheet winding section 1b 10th
As shown in the figure, the holding mechanism section 19 of the ink sheet winding section 1b is in the second state of the ink sheet winding section 1b.
It holds cassettes b, and can be roughly divided into ■Cassette 1
is separated into a main body part 1a and an ink sheet winding part 1b, and is disassembled into two parts: a holding mechanism part that locks the winding part 1b, and (2) an ink sheet winding mechanism part. Here ■
The holding mechanism section will be explained, and the remaining part (2) will be explained in the next section.

As shown in FIG. 10, the holding mechanism of the cassette 1 mainly consists of left and right cassette guides 20a, 2Qb and a connecting plate 2Qc that connects the two. 2Qa is arranged to be located on an extension of the left cassette guide 32, and
0b is arranged so as to be located on an extension of the right cassette guide 31.

The left and right double-force set guides 2Qa, 20b are each provided with a seven-way separation slide plate 21 that is slidable up and down.

This slide plate 21 is also attached to the tip of the plunger 23a of the third solenoid 23.
is configured to be in a high position in the OFF state and in a low position in the ON state.

The slide plate 21 has a protrusion 22 projecting in a 90-degree direction at the bottom, and the slide plate 21 is in the OFF state of the third solenoid 23 when the tip end surface of the ink sheet winding section 1b is in contact with the connecting plate 20C. When the projection 22 is in the high position, it comes into contact with the cassette coupling lever 17b and pushes it up.
Release the lock status.

When the slide plate 21 is in the low position with the third solenoid 23 in the ON state, the protrusion 22 does not come into contact with the cassette coupling lever 17b. Then, the lever 17b is pushed back downward by the biasing force of the lever return spring 17C and is fitted into the pin 18, so that the ink sheet winding section 1b is locked.

Since the protrusion 22 needs to be in the low position only when the ink cartridge Q scraping part 1b enters and exits the holding mechanism part 19, the time it is in the low position is shorter.

Therefore, it is preferable to use a solenoid with a return spring as the third solenoid 23. If this is done, the JIT time for the solenoid 23 will be shortened, and the power consumption of the printer will be reduced.

Further, as shown in FIG. 13, the position of the protrusion 22 is such that the casing 7) of the main body part 1a is placed in a position corresponding to when the ink sheet winding part 1b is in the combined state.
The reason for this is that when you want to separate the cassette 1, you want to push up the cassette coupling lever 17b as close to the lever shaft 17a as possible. Thereby, the moving distance of the coupling portion of the cassette coupling lever 17b can be made longer than the moving distance of the slide plate 21 from the high position to the low position.

9. Ink sheet winding mechanism As shown in FIG. 10, a third motor 111 for winding up the ink sheet is attached above the right cassette guide 20b, and a spring 114 and the like are connected to the output shaft of the third motor 111. Power is transmitted to gear +13 via a friction clutch. In other words, only a torque smaller than a predetermined friction value of 1 to 1 lux can be transmitted to gear +13, and gear 113
When an excessive load is applied to the shaft 112, the shaft 112 idles and the gear 113 does not rotate.

On the other hand, as shown in FIG.
4a, and the rotational force of the third motor 111 is transmitted from the shaft 112 to the gear 113 to the gear 14a.
Rotate the ink sheet take-up roller 14.

10. Image-receiving paper sending-out mechanism section for sending out the image-receiving paper 2 to the platen mechanism section 110.1 Rotating mechanism first of the image-receiving paper sending-out roller 70
As shown in FIG. 1, a gear 71 is attached to the output shaft of the second motor 29.
is attached. On the other hand, the gear 72 is fixed in the middle of the rotating shaft 73 and meshes with the gear 71. The left end of the shaft 73 is fitted and fixed to the input shaft of a clutch 74, and a gear 75 is attached to the output shaft of the clutch 74.

The gear 75 meshes with a circumferential gear 51a, and this gear 51a is connected to the intermittent gear Slb in a -° body.

As shown in FIG. 15, this integrally connected gear 51a
, 51b is integrated around the shaft 55 between the "limit switch detection cam 52, the roller up and down cam 54 of the receiving paper feed roller" and the "limit switch detection cam 53". Rotate.

As shown in FIG. 15, the intermittent gear Slb is meshed with a gear 60, and the gear 60 is further meshed with a gear 61.

As shown in FIGS. 15 and 16, the gear 60 is connected to the bearing 57.
The bearing 57 is rotatably attached to the outer periphery of the
Roller holding lever 56 having a “-” shape when viewed from above
is fixed to the left side of the

On the other hand, a shaft 66 passes through the inside of the bearing 57, and the bearing 57 and the shaft 66 are free to rotate relative to each other. and axis 6B
The right end of is fixed to the substrate 63a. This board 63
a is fixed to the left cassette guide 32.

On the other hand, a bearing 57 is also placed on the right side of the lever 56 in the same way as on the left side.
A bearing 65 corresponding to the
A shaft 67 corresponding to 6 is freely rotatably passed through the shaft 67.
The left end of is fixed to the substrate 63b via a spacer. This board 63b is fixed to the right cassette guide 31.

Therefore, the lever 56 is rotatable about the shafts 66, 67, and the gear 60 is also rotatable about the shaft 66.

As shown in FIG. 17, bearings 58 and 64 are fixed to the left and right side surfaces of the gate-shaped roller holding lever 5G near the bent corners, and the roller shaft 62 passes through the bearings. Therefore, the roller shaft 62 is free to rotate relative to the bearing. The left end of the roller shaft 62 passes through the inside of the bearing 58 and comes out to the outside, and a gear 61 is fixed thereto. A roller 70 is fixed near the center of the roller shaft 62.

Therefore, as shown in FIG. 11, the rotational force of the second motor 29 is: output shaft - gear 71 - gear 72 - rotating wheel 73 - clutch 74 - gear 75 - gear 51a - gear 51b - gear 6.
0-Gear 61-Roller shaft 62-Receiving paper feeding roller 7
0, the roller 70 rotates and sends out the receiving paper.

Umbrella* 10.2 Vertical mechanism of the receiving paper sending roller 70 In order for this roller 70 to rotate and send out the receiving paper from the cassette 1, it is necessary to lower the roller 70 until it comes into contact with the surface of the receiving paper. In some cases, it is necessary to raise the roller 70 because it becomes a hindrance to the conveyance of the cassette 1. For this purpose, a vertical mechanism is required.

As shown in FIG. 18, in this embodiment, the roller 70 is
The lever 56 is attached to the roller holding lever 56 which has a shape of "-", and the lever 56 is rotatable about the shaft 66 as described above.
In Figure 6, rotating it clockwise will cause it to rise, and rotating it counterclockwise will cause it to fall. As a result, the receiving paper feed roller 70 also moves up and down.

As mentioned above, the gears 51a and 51b are limited.

゛ It rotates around a shaft 55 together with the toss inch detection cam 52, the roller up/down cam 54 of the receiving paper feed roller, and the limit switch detection cam 53.

As shown in FIG. 16, the limit switch detection cam 5
3 has a notch for switching 0N1OFF of the 8th limit switch LSw8, gear Sla, 51b
detects that it rotates once.

The limit switch detection cam 52 and the 91st J mint switch LSw9 are 5° tension springs 69 that detect a predetermined angular position during one rotation of the gears 51a and 51b.
The biasing force exerts a force on the lever 5 to rotate it counterclockwise in FIG. 16 and clockwise in FIG. 19. Therefore, in FIG. It is always in contact with the cam follower 68.

As a result, in response to the cam surface, the roller holding lever 56 rotates counterclockwise in FIG. The roller 70 descends and enters the receiving paper feed roller hole 9a of the main body portion 1a, contacts the receiving paper 2, and the roller 70 presses the receiving paper 2 by the biasing force of the spring 69. When the roller 70 rotates in this state, the image receiving paper 2 is taken out by 1j.

Conversely, in response to the cam surface, the roller holding lever 56 moves toward the shaft 66.
When the roller 70 is rotated clockwise in FIG.
Raise to a high position where it is safe to move.

FIG. 16A shows that the protrusion of the cam 54 is in contact with the cam follower 68, the lever 56 is fully rotated clockwise, and the roller 7
0 is at the highest position, and the recess (1) indicates the relationship between the roller 70 and the image receiving paper 2. The two are far apart here. On the other hand, FIG. (2) is a diagram showing the relationship between the intermittent gear 51b and the gear 60 in that state, and the two do not mesh, so the rotation of the gear 51b is caused by the rotation of the gear 60.
Since the gear 61 meshing with the gear 60 does not rotate, the roller 70 connected to the gear 61 does not rotate.

FIG. 16B shows the situation when the cam 54 has rotated a little further from the state shown in FIG. 16A and the cam follower 68 has just passed the protrusion, when the lever 56 has fully rotated counterclockwise and the roller 70 is at the lowest position. This is a diagram conceptually showing the state.
) indicates the relationship between the roller 70 and the image receiving paper 2. Here the two are in contact. Rather, the roller 70 is pressed against the image receiving paper 2 by the biasing force of the bar 269. On the other hand, FIG. 2 is a diagram showing the relationship between the intermittent gear stb and the gear 60 in this state, and the gear portion of the intermittent gear 51b has just started to mesh with the gear 60. Therefore, the rotation of the gear 51b is transmitted to the gear 60, and the gear 6 which meshes with the gear 60
I rotates, the roller 70 connected to the gear 61 rotates, and the image receiving paper 2 begins to be discharged.

FIG. 16C is a diagram conceptually showing a state in which the rotation of the cam 54 has progressed from the state shown in FIG. 16B and the projection of the cam 54 has approached the cam follower 68. FIG. shows the relationship between Here the two are still in contact. However, FIG. (2) is a diagram showing the relationship between the intermittent gear Slb and the gear 60 in that state, and the intermittent portion of the intermittent gear 51b has just started contacting the gear 60. Therefore, gear 5
The rotation of 1b is not transmitted to the gear 60, the gear 61 meshing with the gear 60 stops rotating, the roller 70 connected to the gear 61 also stops rotating, and the ejection of the image receiving paper 2 is stopped.

+1. Platen mechanism umbrella
A metal cylindrical part 76a, a metal side part 76b on both left and right sides of the metal cylindrical part 76a, and a rubber part 7 covered on the outside of the cylindrical part 76a.
It consists of 6G. As shown in FIG. 20, the side surface portion 76b
has a protruding shaft portion 76d at its center, and the platen 76 is pivotally supported by the shaft portion 76d.

As shown in FIG. 20, a gear 77 is attached to the right end of the shaft portion 76d, and this gear 77 is connected to the output shaft of a gear box 78a attached to a first stepping motor 78 as shown in FIG. Gear 7 attached to the tip of
The rotation of this motor 78 causes the platen 76 to rotate in the direction of the arrow shown in FIG.

On the other hand, as shown in FIG. 20, a camshaft 80 passes through the center of the shaft portion 76d, and both can freely rotate relative to each other. However, as shown in FIG.
has a one-position clutch (one pos clutch) on the left end.
tion clutch C4) 81, and this clutch 81 can be turned on and off using an electric signal. When the clutch 81 is turned on, the camshaft 8
0 and the shaft portion 76d (that is, the platen 76) rotate together, and when turned off, the cam shaft 80 is fixed at a predetermined position regardless of the rotation of the shaft portion 76d (that is, the platen 76) and stops rotating. do.

As shown in FIG. 20, a shaft 8 is provided inside the cylindrical portion 76a.
Six cams 82 are attached around the cylindrical portion 76a, and a shaft 83 is attached near the cylindrical portion 76a between the left and right side portions 7Gb.
A total of six claws 84 for image receiving paper and chucking are attached at positions corresponding to the above. The claw 84 is rotatable about the shaft 83, and as shown in FIG.
It is always biased in the direction of the arrow by a torsion bolt 285 attached to the shaft 83.

As shown in FIG. 23, when the claw 84 is viewed from the side,
The left arm 84a, which has the shape of a "m" character, functions to hold down the image receiving paper 2, the right arm 84b, which functions to flip up the image receiving paper from the platen 76 when printing is completed and the image receiving paper is ejected from the platen 76, and the right arm. It has a cam follower part 84C that protrudes downward from the lower end of 84b.

In this way, the claw 84 is in the shape of a square, so it is a single member and can be rotated (closed) clockwise in FIG. 24 by the biasing force of the spring 85 to receive the image. You can press (cha, king) the leading edge of paper 2,
Furthermore, by rotating (opening) the claw 84 counterclockwise in FIG. 25 against the spring 85 using the cam 82, the leading edge of the image receiving paper 2 can be flipped up from the platen 76, which is extremely useful. It is.

To open the pawl 84 by bringing the cam 82 into contact with the cam follower portion 84C of the pawl 84, turn off the fourth clamp 81 to release the camshaft 80 from the platen 76 and move the camshaft 80 to a specified position. Fix the platen 76 at an angle.
Rotate. Then, as shown in FIG. 22, the cam follower portion 84C of the pawl 84 comes into contact with the projection of the cam 82, causing the pawl 84 to rotate counterclockwise and open. At this point, q is the platen origin position as shown in FIG.
(see FIG. 26) turns on the fourth limit switch LSw4 (see FIG. 26) for detecting the origin plane, and based on this ON signal, the power supply to the stepping motor 78 is stopped and the platen 76 is stopped.

To close the pawl 84, turn off the clamp 81 to disengage the camshaft 80 and the platen 76, fix the camshaft 80 at a predetermined angle, and then close the platen 76.
Rotate in the direction of the arrow in Fig. 22. Then, the second
As shown in FIG. 4, the cam follower portion 84C of the claw 84
is released from the protrusion of the cam 82, and as a result,
Due to the urging force of the spring 85, the pawl 84 rotates clockwise in FIG.
chucking between. FIG. 24 shows this state.

11.2 Rotation Mechanism of the Platen 76 On the other hand, to explain the rotation mechanism of the platen 76, as shown in FIG. 21, the gear 79 attached to the output shaft of the gear box 78a of the first stepping motor 78 is gear 77
The gear 77 is fixed to the tip of the rotating shaft 76d.

As shown in FIG. 20, the rotating shaft 76d is connected to the platen 7.
6 is supported. Therefore, the rotational force of the motor 78 is
The platen 76 rotates through transmission between the gear 79, the gear 77, the rotating shaft 76d, and the platen 76.

12. Thermal Head 3rd Elevating Mechanism FIG. 27 is a perspective view of the elevating mechanism of the thermal head 36.
The figure is an exploded perspective view seen from the rear direction.

The thermal head 36 is mounted on a stand 37,
The mounting table 37 is rotatable about a shaft 38. The shaft 38 is attached to a carriage 39, and the carriage 39 is fixed to a frame 40. Furthermore, the left and right frames 40 each have a frame stand 41.
is attached to. The spring 42 is located between the frame base 41 and the mounting base 37, and constantly pushes the mounting base 37 upward to create contact pressure between the thermal head 3 and the platen (not shown). There is.

The stopper 43 is installed on the side of the stand 37 to prevent the stand 37 from rising unnecessarily when the thermal head 36 is not in pressure contact with the platen, and is mounted on the bottom of the frame 40. When it is attached, the base 37 cannot be raised any further.

The ends of the ink sheet guide rollers 44a, 44b, and 44C are pivotally supported by the left and right frames 40.

Generally, the guide roller for the ink sheet is attached to the platen side, but here, the guide roller for the ink sheet is attached to the frame 40.
Attach to. The reason for this is that in order to prevent the occurrence of wrinkles when the ink sheet moves, the line of contact between the thermal head 36 and the platen must be
However, since the contact line changes depending on how the thermal head 36 touches the platen, the contact line must be exactly parallel to the axis 38 of the stand 37. The ink sheet guide roller 4
This is because by similarly supporting the shafts 48 to 44C, the parallel 1 can be made more advanced.

Guide rollers 39b and 39C are attached to the carriage 39, and the carriage 39 can move up and down along the guide plate 45. To explain the means for moving the carriage 39 up and down, a cam 46 is mounted on a cam follower 392 attached to the carriage 3S, and when the cam 46 rotates, the cam follower 393
moves up and down, and as a result, carry and gear 39 move up and down.

Figure 'J27A is a diagram conceptually showing the relationship between the cam 4 days, the cam follower 392, and the thermal head 3 days.
1, the large diameter portion of the cam is in contact with the cam follower 39a, and the thermal head 36 is at a high position. Printing is performed at this time.

In (2) of the same figure, the inner diameter portion of the cam is in contact with the cam follower 3Sa, and the thermal head 3 is at the middle position. At this time, printing preparations have been completed.

In FIG. 3(3), the small diameter portion of the cam is in contact with the cam follower 39a, and the thermal head 36 is at a low position. At this time, the cassette l is transported.

As shown in FIG. 27, the cam 46 and the gear 48 are rotatably attached to the same shaft 49d, and both rotate together. Then, as shown in FIG. 27, the gear 48
and gear 47 are meshed.

As shown in FIG. 11, the gear 47 is attached to the left end of the rotating shaft 47a, and the gear 47b is attached to the right end. The gear 47b meshes with a gear 51, which is attached to the output shaft of the electromagnetic clutch 50. On the other hand, a gear 50a is attached to the tip of the input shaft, and this gear 50a meshes with a gear 71.

The gear 71 is attached to the output shaft of the second motor 29 as described above.

Therefore, referring to FIG. 11, the transmission path of the rotational force of the second motor 29 will be explained. Gear A 71 attached to the output shaft of the motor 2S - gear 50a - second clutch 50 - gear A 51 -Gear 47b-・Rotating shaft 47a-
The cam 46 rotates through transmission with gear A 47, gear 48, and cam 46.

As shown in FIG. 27, 5.6.7 limit switch, CHLSw5. LSen 6. Cams 49a, 49b, and 49c that turn LSi*7 ON and OFF are also coaxially connected to the cam 46 with a gear 48 in between, and when the cam 46 reaches a predetermined rotation angle, the limit switch LSw5. L
Sw6. LS 匈7 is also turned on and off. Limit switch LSw5゜LSw6. The reason why three LSw7 are provided is to detect the high position, middle position, and low position of the thermal head 36 in that order.

13. Guide and discharge mechanism for image-receiving paper 2 to platen 76 FIG. 26 shows the upper part of a printer having a mechanism for guiding image-receiving paper 2 to platen 76 and a discharge mechanism for discharging thermally transferred image-receiving paper 2, that is, prints. FIG. 29 is an explanatory diagram conceptually showing the right side thereof.

As shown in FIG. 29, guide plates 92 and 93 are provided in front of the platen 76, and guide plates 92 and 93 are provided upwardly from the outlet 9b of the cassette main body 1a loaded in the lower part of the printer by the receiving paper feed roller 70. The ejected image-receiving paper 2 continues on the guide cloth 92 by the roller 7o, and eventually comes into contact with the guide sheet 93 and moves along the path toward the platen 7.
It can be changed towards the bottom of G.

Around the platen 76, a pressure roller 94 is disposed on the side closer to the thermal head, and another pressure roller 87 is disposed above the platen 76 in order to press the wound receiving paper 2 against the platen 76. .

The pressure roller 94 is attached to one end of a lever 95 shaped like a "<", and the other end of the lever S5 is attached to a tension spring 96.
It is biased counterclockwise in FIG. 29. This biasing force is transmitted to the pressure roller 94 by the lever 95 rotating around the rotating shaft 95a located at the bending point.
The roller 94 is pressed against the platen 76.

Another pressure roller 97 is located above the platen 76 and is fixed.

On the other hand, a pair of substantially parallel guide plates 98 and S9 are provided to discharge the printed image receiving paper. One end of the guide plates 98 and 99 is open above the platen 76, and the image receiving paper 2 advances between the guide plates 98 and 99. Guide plate 88.
The other end of 99 communicates with a receiving paper outlet 25 (see FIG. 8). However, since the image-receiving paper 2 cannot advance between the guide plates 98 and S9 to the ejection port 25 with its own blade, a pair of ejection rollers 10 are provided in the middle as shown in FIG.
0 (for driving) and 101 (for pressure contact) are provided.

At the left end of the rotating shaft 10 that supports the paper ejection roller 100,
As shown in FIG. 26, a pulley 104 is attached, while a platen 7 is attached as shown in FIGS. 21 and 26.
A pulley 103 is attached to the left end of the shaft portion 76d that pivotally supports the platen origin position detection cam 76a, and a belt 103 is attached between the pulley 103 and the pulley 104.
05 is applied.

The diameter ratio of pulleys 103 and 104 is approximately 621, and platen 7
6 and the paper ejection roller 100 is set to approximately 4:1. Therefore, the circumferential speed ratio between the platen 76 and the paper discharge roller 100 is approximately t:t, 5. This is because the leading edge of the image receiving paper 2 reaches the paper ejection roller 100 after printing is completed, and
One is to prevent the receiving paper 2 from becoming loose or wrinkled when the paper is ejected, and the other is the time from when the rear end of the receiving paper 2 passes the pressure roller S7 until the end of ejecting the paper. This is to shorten the time.

Note that while the leading edge of the image receiving paper 2 is sandwiched between the paper ejection rollers 100 and 101, but the rear end is still sandwiched between the pressure roller 97 and the platen 76, the pressure roller 97 and the platen 76 are Because the holding force is strong, the paper ejection roller 10
0 rotates with some slippage.

As shown in FIG. 29, a discharge port 25 and a paper discharge roller 100
The distance from the image receiving paper 2 is designed to be somewhat shorter than the length of the image receiving paper 2. Therefore, the rotation of the platen 76 stops at the origin position,
When the paper ejection roller 100 also stops rotating, the image receiving paper 2 also stops, but the image receiving paper 2 stops at a position where the leading edge thereof is slightly out of the ejection port 25. Therefore, the image-receiving paper 2 does not fall from the printer, and the operator can easily take out the image-receiving paper 2 by hand, which is convenient.

On the other hand, the paper ejection roller 101 that forms a pair with the paper ejection roller 100 is a pressure roller that presses the paper ejection roller 100 against the flower.
As shown in FIG. 26, it is supported by a rotating shaft 107.

Both ends of the rotating shaft 107 are fitted into bearing holes 109 and +10 provided in the frame plate 108 of the ejection mechanism section. These bearing holes 109 and 110 are long vertically, so the paper ejection roller 1
01 can move up and down freely. However, pressure springs 102 are provided on the left and right inside the frame plate 108, and the rotating shaft 10
7 is always pushed down. Therefore, the paper ejection roller 10
1 is in pressure contact with the roller 100.

14. Cassette position detection rimino switch 1iYAs shown in FIG. 10, the left cassette, F guide 32 has a first limit switch L, 5ii1. 2nd rim in the back,
In addition, the left side cassette guide 20 of the ink winding section holding mechanism section 19 is arranged.
A third limit switch LSw3 is arranged at a.

These LSwl to 3 are for detecting the position of the cassette 1, and the positive position 1 of the LSwl from the cassette i inlet 24 is at a position shorter than the entire length of the cassette 1. Therefore, when cassette 1 is installed, cassette 1
The tip of the switch operates the first limit switch LSwl, turning this switch ON. This ON signal causes the second
The motor 2S starts rotating, and this rotation is transmitted to the cassette 3 rubber feed roller 30 via the drive system, and the roller 30 rotates to carry the cassette deep into the printer.

Next, the tip of cassette 1 is connected to the second limit switch LSw.
2 is activated to turn it on, and when it advances further and reaches the holding mechanism section 19, it activates the third limit switch LSw3 and turns it on. At this time, the first limit switch LSw
l is removed from the cassette 1 and turned OFF.

The overall length of the cassette 1 and the positional relationship of the limit switches LSwl, LS2, and LS23 are set as described above. Therefore, the following is detected in the signal LSwl~3.

Table 1 (Position detection of cassette 1) Figures 31 to 49 are for explaining the sequence of printer operations, and all show the inside of the printer from the right side, showing the positional relationship of the main parts. It is a conceptual diagram.

In addition, Fig. 30 shows the inside of the printer when viewed from the right side.
A group of limit switches LS, a thermal head 36,
7 is a conceptual diagram showing the positional relationship among the platen 76, the first solenoid 33, the third solenoid 23, the platen origin position detection cam 76e, and the receiving paper feed roller 70. FIG.

15. Automatic loading operation of the cassette 1 (see Figures 31 and 32) When the power switch 115 shown in Figure 8 is turned on, the first solenoid 33 for locking the cassette/main unit 1a and the cassette separation shown in Figure 10 are activated. 3rd solenoid 23 for
The plungers are retracted into the solenoids and the cassette 1 can be loaded as shown in FIG. 31.

When the cassette 1 is inserted into the cassette mounting port 24, the tip of the cassette is connected to the first limit switch LS shown in FIG.
Activate wl and turn this on. This ON signal starts i+1 power to the second motor 29 and the electromagnetic clutch 35, and the rotational force of the second motor 29 is transferred from the gear 71 to the gear 72 to the shaft 73 to the electromagnetic clutch 3, as shown in FIG.
It is transmitted to the cassette conveyance rubber roller 30 through a drive system of 5-gear 26-gear 27-gear 28, and the cassette 1 is carried into the back of the printer.

As cassette 1 moves deeper, the tip will eventually become the 10th cassette.
Operate the second limit switch LSw2 shown in the figure to
Set it to N. This ON signal starts energizing the third motor 111, causing the gear 113 to rotate. The rotation of the gear 113 allows the gear 113 to smoothly mesh with the ink sheet take-up roller gear 14a of the ink sheet take-up portion 1b of the cassette.

Then, the cassette 1 advances further, and when it reaches the ink sheet winding section holding mechanism section 19, the tip end is at the tenth position.
Operate the third limit switch LSw3 shown in the figure to
Set it to N. At this time, the first limit switch LSwl is removed from the cassette 1 and turned OFF. This is the state shown in Figure 32, the total length of cassette 1 and the limit switch LS.
wl.

The relationship with 2.3 is set as shown in Figure 32.
LSwl: OFF LSw2: 0N LSwl; ON It is detected that the cassette 1 is in the first predetermined position which is the innermost position, and based on this detection signal, the second motor 29 and the third motor 111 are Power is cut off,
As a result, the cassette 1 stops at the first predetermined position, and the gear 1
13 also stops rotating.

16. Separating operation of cassette 1 (see Fig. 32) When it is detected that the cassette II has reached the first predetermined position, the first
The power supply to the third solenoid 23 shown in FIG.
(see FIG. 2) and comes into contact with the cassette coupling lever 17b (see FIG. 6), and further pushes up the lever 17b to release the lock. The protrusion 21b, now at a high position, maintains that state until it is energized again, prevents the separated ink sheet 1-6 scraping portion 1b from retreating from the holding unit 19, and maintains the position. Fix it.

After a while, a reverse rotation signal is sent to the second motor 29, and the cassette conveying rubber roller 30 is reversely rotated to move the main body 1a.
only begins to retreat.

Then, the main body 1a operates the first limit switch LSwl again and turns it ON, and as the main body 1a moves further backward, the second limit switch LSw2 comes off from the main body 1a and turns OFF as shown in FIG. becomes.

As a result, LSSi2ON LSw2:OFF LSw3:ON is established, and based on this signal, the second motor 29 and the electromagnetic clutch 35 are de-energized, and the main body 1a stops moving back and stops at the second predetermined position.

However, it is difficult to stop the main body 1a instantaneously due to the rotational torque of the motor and other reasons.
In fact, when it is detected that the cassette 1 has reached the innermost first predetermined position and the power supply to the third solenoid 23 is stopped, at the same time the first solenoid 3 with a return spring is
3 (see FIG. 10) is also stopped. This first solenoid 33 is for locking the main body portion 1a, and when the power supply is stopped, the plunger 34 is designed to pop out from inside the solenoid by the urging force of the return bar.

However, when the cassette 1 is in the first predetermined position, the head of the plunger 34 is in contact with the bottom of the main body 1a. The head of the plunger 34 has a hemispherical shape, so that when the main body 1a retreats, there is no problem even if the head comes into contact with the bottom of the main body 1a. Then, when the position of the locking hole +1a provided at the bottom of the main body portion 1a matches the position of the head of the plunger 34, the head protrudes due to the biasing force of the return spring and fits into the hole 11a. The main body portion 1a is instantly stopped and locked at the same time.

This state is shown in FIGS. 33 and 13, and corresponds to the "second state" in the present invention.

Also, by stopping the power supply to the first clutch 35,
Power transmission between the second motor 29 and the cassette conveying rubber roller 30 is separated.

The ink sheet 4 is now in a bridging state between the main body portion 1a and the ink sheet winding portion 1b in the second state, and the setting of the cassette 1 is completed.

Further, the position of the main body portion 1a in this state is referred to as a second predetermined position.

17. Moving operation of the thermal head 36 from the low position to the middle position (see FIG. 34) The thermal head 36 takes three digits: high, middle, and low. When the cassette 1 enters the first predetermined position (31st to 33rd positions)
In Figure), the thermal head 36 is at a low position.

As explained in the previous section 16, when the loading of the cassette is completed, the second clutch 50 is turned on and energization to the second motor 2 is started, and the rotational force of the motor 28 is as shown in FIG. As such, gear 71 - gear 50a - clutch 50 - gear 51 - gear 47b - rotating shaft 47a - gear 47
- It is transmitted to the cam 46 via the gear 48, thereby causing the thermal head 36 to rise.

When the cam 46 shown in FIG. 27 rotates, the cams 49a, 49b, and 49c, which were rotating in
Turn Sw5, LSw6, and LSw7 off and on, respectively.
OFF, and the second clutch 50 is turned OFF based on this signal.
At the same time, the second motor 29 is turned off, and the thermal head 36 stops at the middle position.

FIG. 34 shows this state, and printing preparation is now complete.

18. Feeding operation of image receiving paper 2 (see Fig. 35) Turn on the print switch 116 when printing preparation is completed.
Then, the second motor 2S starts to be energized and rotates, and as shown in FIG. 11, the gear 71 directly connected to the motor 2S
rotates. This rotation is transmitted from gear 71 to gear 72, and a human power shaft 73 to the clutch rotates. When the third clutch 74 is ON, this rotation is transmitted to the gear 75 coupled to the output shaft, and the gear 75 rotates.

When the gear 75 rotates, the circumferential gear 5ta meshing with it rotates, and the intermittent gear Slb integrated therewith also rotates.

As shown in FIG. 16, as the gears 51a and 51b rotate, the mechanical up/down cam 54 that is integrally connected to these gears rotates, and the cam follower 68 that was in contact with it rotates.
begins to fall. As a result, the roller holding lever 56 is
Rotating counterclockwise in FIG. 16 around 6.67, the receiver paper feed roller 70 moves toward the cassette main body 1a.
contacts the image-receiving paper 2 through the opening 9a and presses the image-receiving paper 2. This state is shown in FIG. 16B (1).

During this series of operations, as shown in FIG. 16A (2),
Since it corresponds to the intermittent part of the intermittent gear 51b, the gear 51
Despite the rotation of b, the rotation is not transmitted to the gear 60, and therefore the gear 61 does not rotate, so the roller shaft 62 and the receiving paper feed roller 70 do not rotate.

After that, as shown in FIG. 16B (2), the intermittent gear 51
When b rotates and meshes with the gear 60, the rotation of the gear 51b is transmitted to the gear 61 via the gear 60, and the roller shaft 6
2 and the receiving paper feed roller 70 rotate. Then,
The image receiving paper 2 is discharged from the image receiving paper outlet 9a and passes through the guide plate 9.
2, then diagonally downward along the guide plate 93, and eventually the platen 76 as shown in FIG.
comes into contact with.

When the ejection of a predetermined length of the image receiving paper 2 is completed, the limit switch detection cam 52 shown in FIGS. 16 and 18 moves to the ninth position.
The limit switch/chi LSw9 is turned on, and based on this ON signal, the power supply to the second motor 29 is stopped, and the gear 51 is turned on.
rotation also stops. FIG. 16C shows this state.

Thereafter, when chucking of the image receiving paper 2 to the platen 76, which will be described in detail in the next section 19, is completed, the second motor 29 is energized again, and the gears 51a, 51b and the cam 54 rotate. Eventually, the cam follower 68 rides on the protrusion of the roller up/down cam 54, and as a result, the receiving paper feed roller 70 rises and separates from the receiving paper 2.

At the same time, the limit switch detection cam 53 turns on the eighth limit switch LSw8 (state Li in FIG. 16), and based on this ON signal, the power supply to the second motor 29 is stopped, and the gears 51a, 51b, and others are set to exactly 1. It stops when it rotates. FIG. 16A shows this state.

19. Chucking the image receiving paper 2 onto the platen 76 (second
(See Figures 2 and 35) The image receiving paper 2 is transferred to the cassette 1 by the image receiving paper feeding roller 7o.
The state shown in FIG. 22 is when the paper is ejected from the platen 76 and stops when it comes into contact with the platen 76. The platen 76 is at the origin position.

As explained in Section 18, when the limit switch detection cam 52 shown in FIGS. 16 and 18 turns on the ninth limit switch LSw9, and based on this ON signal, the power supply to the second motor 29 is stopped. , 1llll power to the stepping motor 78 is started based on the same ON signal,
The platen 76 starts rotating in the direction of the arrow from the origin position shown in FIG.

When the platen 76 rotates in the direction of the arrow, the platen 76
The fourth clutch 81 connecting the camshaft 80 and the camshaft 80 is OFF.
In this state, the camshaft 80 is fixed at the original position by a brake mechanism (not shown) attached to the fourth clutch 81.

Nevertheless, as the platen 76 continues to rotate, the cam follower portion 84 which was in contact with the protrusion of the cam 82
C is released from the cam 82, and the claw 84 is rotated clockwise by the biasing force of the spring 85. As a result, the leading edge of the image receiving paper 2 is caught between the left arm 84a and the platen cylindrical portion 76a. Then, the leading edge of the image receiving paper 2 is chucked to the platen 76. FIG. 24 shows this state.

When the platen 76 is further rotated after the chucking is completed, the power supply to the motor 78 is stopped at a predetermined rotational angle position, and the platen 76 is stopped. Simultaneously with the stop, the fourth clutch 81 starts to be energized, and the clutch is turned on (connected).

When the clutch 81 is turned on, the camshaft 80 (that is, the cam 82) rotates in synchronization with the platen 76, so even if the platen 76 rotates after this, the state shown in FIG. 2 is chucked on the platen 76.

20. Winding and stopping operation of ink sheet 4 (36th
(See figure) As explained in the previous section 19, when the platen 76 stops at a predetermined rotational angle position, the J1 power to the third moke 111 shown in Fig. 13 is started and the gear 113 starts rotating.
As a result, the ink sheet 4 is wound around the take-up roller 14. Then, move (wind up) the ink sheet 4
The first photodetector (OP-1
) detects the beginning of the Y color ink layer area, the third motor 111 is de-energized and winding is stopped, and the second solenoid 86 shown in FIG. 10 is turned on.
The plunger 87 pushes the rubber ring 13a shown in FIG. 5 through the hole 11b of the cassette main body 1a, and the ink sheet supply roller 13 is locked. This state is the 36th
It is a diagram.

21. Moving operation of the thermal head 36 from the middle position to the high position (see Fig. 37) The first photodetector (OP-1) shown in Fig. 27 detects the beginning of the Y color ink layer area □ Feeding the ink sheet 4 until this leading force < 8 moxibustion is exerted is referred to as Y color "heading" □□, and based on this detection signal, the ink sheet supply roller 13 is locked, and the second clutch is 50 is turned on, and power supply to the second motor 29 is started, causing the motor to rotate. This rotational force is transmitted to the gear 48 through the second clutch 50 as described in Section 12, and the rotational force of the gear 48 is transmitted to the integrally coupled cam 46, thereby causing the throat 36 to rise toward the thermal.

When the rotational position of the cam 46 shown in FIG. 27 reaches a predetermined rotational angle position, the fifth limit switch LSw5 is turned ON, the sixth limit switch S-6 is turned 0FF1, and the seventh limit switch LSw7 is turned OFF. Based on this, it is determined that the thermal head 36 is at the high position shown in FIG. 27A (1), and the power supply to the motor 29 is stopped. At this time, the image receiving paper 2 and the ink sheet 4 are pressed between the platen 76 and the thermal head 36 by the force of the spring 42 shown in FIG.

Print preparation is now complete. After this, if there are no particular problems, the process will automatically proceed to the next step.

22. Y color printing operation (see FIG. 37) As explained in Section 21, based on the signals LSw5:ON LSw6:OFF LSw7:OFF, the power supply to the second solenoid 86 is stopped and the ink sheet supply roller 13 is unlocked,
On the other hand, energization of the third motor 111 and the stepping motor 78 is started.

The stepping motor 78 is energized by pulses (intermittent).
Therefore, the image receiving paper 2 advances intermittently one line at a time. In this case, the ink sheet 4 is superimposed on the image receiving paper 2, and since both are pressed between the platen 7 and the thermal head 36, they become one body due to mutual rubbing.

On the other hand, the third motor 111 is a DC motor that rotates continuously, but as explained in Section 9 (see Figure 14), if a load of more than a predetermined value is applied to the gear 113, this motor will stop idling. Then, ink sheet 4 does not advance.

That is, the advancement of the image receiving paper 2 and the ink sheet 4 is controlled or driven by the platen 76, and the rotation of the third motor 111 merely serves to wind up the ink sheet 4.

In the current state, the thermal head 36 is in a high position, the image receiving paper 2 and the ink sheet 4 are in pressure contact between the platen 76 and the thermal head 36, and the platen 76 is in pressure contact with the thermal head 36.
6 is stopped. To start printing, press platen 7.
6 is rotated and the thermal head 36 is not energized at the same time.

If they are done at the same time, ■ Backrun of the drive system gear will cause print position deviation for several lines from the start of printing, and ■ Printing will start before the stable cycle of the stepping motor 78 is reached, so A print position shift occurs between ~2 lines.

In order to avoid those inconveniences, for example, between 10 lines,
The platen 76 remains in pressure contact at the same cycle as during printing.
is rotated to perform idle feeding, and then the thermal head 36 is energized to print the first row.

Next, the ink sheet 4 and the image receiving paper 2 are advanced by one line and stopped, and the second line is printed.

Below, if you print up to the last line in the same way, the receiving paper 2
A Y-color two-dimensional image is reproduced above.

When the 7-color printing is completed, the power to the thermal head 36 is stopped, and the receiver paper 2 and the ink sheet 4 are fed by a predetermined amount while being in pressure contact, and then the power to the stepping motor 7B is stopped. to stop the platen 76.

The reason for performing dry feeding in this pressure-welding state is described below.
As a method to cue up colors after M color (including M color),
■ A method of detecting each color (Y, M, C) with a sensor and winding up the ink sheet 4 to control it, or ■ Y, M, C
A marking is provided at a position corresponding to the mark using a margin or the like, and the marking is detected and the ink sheet 4 is wound up.
There are several ways to control it, but the former ■ is for each color (Y, M, etc.).

The need to identify C) increases costs by preparing a plurality of sensors, and the latter also has drawbacks such as high costs due to marking in the margins of the ink sheet 4.

In this embodiment, only the Y color is detected by a pair of sensors (a light emitting part and a light receiving part), and after the ink sheet 4 is wound up and controlled, the cueing of the M color and subsequent colors is performed using the image receiving paper 2, the ink sheet 4
is fed by a predetermined amount while in a pressed state, thereby bringing the top position of the two-color ink layer region of the ink sheet to the printing position rrz of the thermal head 36<position of the heat generating part).

23, M color print 4! (Refer to Fig. 38) As explained in the previous item 22, when the predetermined amount of empty feeding is completed while the pressure contact state is maintained, that is, when the M glans positioning is completed, using this as a signal, 1. Stepping. 2. The second solenoid 86 is turned on and the ink sheet supply roller 13 is locked again; 3. The second motor 2S is energized in the opposite direction. Then, reverse rotation (in the direction of arrow 11 in FIG. 27A) begins, and as a result, the thermal head 36 begins to descend.

When the thermal head 36 descends to the middle position, LSw5
:OFF LSw6:0N LS7:OFF, the middle position is detected, and based on this detection signal, 1fIl? to the second moke 29? ii is stopped, and the thermal throat 36 is stopped at the middle position.

However, since the power supply to the third motor III is not stopped, the ink sheet 4 is about to be wound up. By this operation, even if wrinkles were generated on the ink sheet 4 during seven-color printing in the previous process, the wrinkles are smoothed out. This wrinkle smoothing is preferably performed for each color to prevent accumulation.

Next, based on the middle position detection signal, the second clutch 50 is turned on, and the second motor 29 starts to be energized, causing the motor to rotate. As a result, the thermal head 36 rises, and when it reaches the high position, the second clutch 50 is turned on. The power supply to the motor 29 is stopped and the motor 29 stops. Thereafter, energization of the stepping motor 78 is started, and the platen rotates until 10 lines before the start of M color printing, and then stops.

This completes the preparation for M color printing, and if there are no particular problems, the process will automatically proceed to the next step.

24. M color printing operation (see FIG. 39) Following the previous step, the following operation is similar to the Y color printing operation.

25.0-color print preparation (see FIG. 40) Following the previous step, the following operations are similar to the M-color print preparation.

26. C color printing operation (see FIG. 41) Following the previous step, the following operation is similar to the Y color printing operation.

In this way, three-color images of Y, M, and C are superimposed and printed on one image-receiving paper 2, and a full-color image is reproduced.

27. Ejection operation of the image-receiving paper 2 after printing (42nd
(See figure) When the 0-color printing is completed and all printing is completed, the ink sheet 4 and the receiver paper 2 are continuously fed by a predetermined rotation angle while being in pressure contact, and then the power supply to the stepping motor 78 is stopped. The platen 76 stops.

Next, as shown in FIG. 42, the second solenoid 86 is turned on to lock the ink sheet supply roller 13, and at the same time, the second motor 29 starts to rotate in reverse, and the thermal head 36 is turned on.
begins to descend. LSw5 is OFF, LSw5 is ON,
When LSw7 is turned OFF, the second moke 29 is stopped, and the thermal head 36 is stopped at the intermediate plane. At this point, the power supply to the second clutch 50 is stopped and the clutch is disengaged, and even if the second motor 29 rotates thereafter, the thermal head 36 does not move too much.

Based on the signal that the thermal conductor 36 has reached the intermediate plane, energization to the stepping motor 78 is started and the platen 7
G rotates again, and at the same time, the fourth clutch 81 shown in FIG.
76d) shown in the figure is disconnected from the camshaft 80, and the camshaft 80 and cam 82 are fixed at their original angular positions by the action of a brake mechanism (not shown).

On the other hand, the platen 76 continues to rotate further, and as shown in FIGS. 7J and 25, the position of the pawl 84 in the platen 7G once again passes the position of the pressure roller 97 directly above it, and the platen 76 and the pawl 84 come together again. Cam follower section 84 of rotated pawl 84
C begins to come into contact with the protruding part of the cam 82, and the pawl 84 gradually rotates around the shaft 83 against the biasing force of the torsion spring 85, and the left arm (clamp part) 84a of the pawl is released from the metal cylindrical part 76a of the platen. Separate chucking is released. When it rotates further, the tip of the right arm (protrusion) 84b now protrudes from the surface of the rubber portion 76C of the platen, thereby causing the tip of the image receiving paper 2 to protrude outward from the outer peripheral surface of the platen.

As a result, the leading edge of the image-receiving paper 2 largely rises from the outer circumferential surface of the platen 76 with the aid of its own repulsion elasticity, and as the platen rotates, the lower guide plate 9
Ride on top of 9. Thereafter, the image-receiving paper 2 advances between the pair of guide plates 98 and 99 as the platen rotates, and eventually the leading edge of the image-receiving paper 2 is caught between the ritual rollers 100 and 101.

Thereafter, the image receiving paper 2 is transferred to the platen 7 as shown in FIG.
The rotation of the roller 100, which is driven to rotate from the roller 6 through the pulley 103, the heald 105, and the pulley 104, further advances between the guide plates 98 and 99, and when the tip of the image receiving paper 2 is slightly out of the discharge port 25, the image receiving paper 2 is removed. The rear end passes the roller 100 and the image receiving paper 2 stops. In other words, the outlet 25
The distance between the paper ejecting rollers 100 and 101 (shown in FIG. 29) is designed to be slightly shorter than the total length of the image receiving paper 2, so that the image receiving paper 2 after printing is as shown in FIG. 44. Since the leading end stops at a position slightly protruding from the printer, there is no problem of the receiving paper 2 falling from the printer, and the operator can easily take out the receiving paper 2 by hand.

-4. Regarding the platen 76, after releasing the chucking of the image receiving paper 2, the platen 76 passes through the origin position once before finishing discharging the image receiving paper 2, and then rotates one more time to reach the second position.
The first time the home position is set to 4th limit switch LSw4 is turned ON.
When detected, the stepping motor 78 is de-energized and the platen stops at the original position. This means that the platen 76 has rotated five times, counting from the beginning.

Note that, based on the ON signal of the LSiv4 described above, the second solenoid 86 and the third motor 111 are de-energized, the ink sheet supply roller 13 is unlocked, and the winding of the ink sheet 4 is stopped. .

All printing operations are now complete.

29. How the printing operation ends when the last receiving paper 2 in the cassette is printed When the last receiving paper 2 to be printed is ejected from the cassette 1, the second photodetector (shown in FIG. 13) OP-
When 2) detects that there is no image receiving paper 2 through the window 10 of the cassette main body 1a, the cassette 1 must be replaced. Therefore, the way the print operation is completed changes somewhat.

When the 0-color printing is completed and all printing is completed, the pink motor 7B is moved forward by a predetermined rotation angle.
The power supply to the platen 76 is stopped, and the platen 76 is stopped.

Next, as shown in FIG. 45, the second solenoid 87 is turned on to lock the ink sheet supply roller 13, and at the same time, the second motor 29 starts to rotate in reverse, and the thermal head 36
begins to descend. LSw5 is OFF, LSi*6 is OFF
When FSLSw7 is turned on, the second motor 29 is stopped and the thermal head 36 is stopped at a low position. At this point, the power supply to the second clutch 50 is stopped and the clutch is disengaged.After this, even if the motor 29 rotates, the thermal head 3
6 never moves.

Based on the signal that the thermal head 36 has reached the low position, the stepping motor 78 starts to be energized, and the platen 7
The sun rotates again and at the same time the 4th clutch 81 is OF
F, and the cam shaft 80 and cam 82 are fixed at the original angular position.

Then, as the platen 76 continues to rotate, the chucking is released when the pawl 84 passes the position of the pressure roller S7 as explained in Section 27, and the guide plates 98 and 99 are released as shown in FIG. The paper is ejected during

When the platen 76 rotates a total of five times and reaches the home position as shown in FIG.
8 is stopped, and the platen stops at the origin position.

29. Combining operation of cassette 1 (see Figure 48) above-mentioned L
Based on the “ON” signal of Sw4, l, second solenoid 86
2. The first solenoid 33 is started to be energized and the cassette main body 1a is unlocked; 3. The first clutch 3
5 is ONL. 4. The second motor 29 starts rotating, and the cassette conveying rubber roller 30 shown in FIG. 10 rotates forward to move the main body 1a toward the back. At this time, the third motor 111 is still rotating and the ink sheet 4 is taken up by the take-up roller 14.

Then, when the main body part 1a reaches the innermost first predetermined position, LSwl:0FF LS2=ON LSw3:ON, and when this state is detected, the power supply to the second motor 29 is stopped and the main body Section 1a stops.

At the same time, the third solenoid 23 is energized and the cassette separation slide plate 21 is lowered, so that the cassette coupling lever 17b is moved by the biasing force of the spring 17C (in FIG. 6).
Rotate counterclockwise so that the notch 17e of the lever is connected to pin 1.
8 and becomes locked, and the assembly of the cassette 1 is completed as shown in FIG.

30. Description of ejecting operation of cassette 1 When the assembly of the cassettes 1 is completed, a reverse current is applied to the second motor 29, and the main body 1a starts to move backward.

When the signal LSwl:ON LSw3:OFF is detected, the a current to the second motor 29 and the first clutch 35 is stopped, the rotation of the motor is stopped, and the clutch is set to 0FFL and the case is closed. y l-1 stops at the third predetermined position. At this time, as shown in FIG. 49, the total length of the cassette 1 is designed to be longer than the distance between the cassette and mounting port 24 on the front of the printer and LSw2, so the front of the cassette f-1 is closer to the mounting port 24. The cassette 1 protrudes slightly and stops, so that the cassette 1 does not fall from the printer and can be easily taken out by the operator.

This completes the ejection operation of cassette 1.

(Effects of the Invention) As described above, the present invention provides a compact recording material cassette for a thermal transfer printer that is easy to manage and replenish.
