Field of Industrial Application) The present invention relates to a novel recording device. Specifically, a cut-sheet type recording paper and a transfer paper carrying ink that develops color when transferred to the recording paper are used, and the print head is brought into pressure contact with a platen roller through the transfer paper and the recording paper. A recording device that performs recording, in particular, a recording paper storage section that stores recording paper, a supply spool that winds transfer paper, and a take-up spool that has a fixed drawing end of the transfer paper that stores transfer paper. Using a transfer paper/recording paper cartridge that is integrally equipped with a storage section, take out one spool from the installed transfer paper/recording paper cartridge and insert it across the platen roller, almost opposite to the transfer paper/recording paper cartridge. This relates to a recording device that loads transfer paper by transporting the transfer paper to a position where the transfer paper passes through a path that crosses a platen roller, and the number of drive means and the burden on the control circuit can be reduced. The present invention aims to provide a new recording device that can significantly reduce costs and increase operational reliability.

(B. Summary of the Invention) The recording device of the present invention is capable of moving the print head between the position where the spool is transferred and the position where it is pressed against the platen roller, and the transfer paper/recording paper mounted thereon. The movement of the push-up arm that is inserted into the recording paper storage section of the cartridge and presses the recording paper against the paper feeding means, that is, the paper feeding means that feeds the recording paper to the platen roller, is driven by one driving means. This makes it possible to reduce the number of driving means and reduce the burden on the control circuit, thereby significantly reducing costs. Since the movement order of the head and push-up arm is mechanically regulated, reliability of operation can be improved.

(C, Prior Art) [Fig. 26 For example, recording by a recording device such as a printer is often performed by transferring ink carried on a transfer paper to the recording paper by a print head. Specifically,
The recording paper is run in a state in which it is in wound contact with the platen roller, and the transfer paper is run in synchronization with the recording paper while the print head is brought into pressure contact with the platen roller via the transfer paper and the recording paper, and , Long sheets of transfer paper are often used, and when loading such a form of transfer paper into a recording device, the supply spool wrapped with the transfer paper and the pull-out end of the transfer paper are fixed. This is done by mounting the take-up spool in a predetermined mounting position.

FIG. 26 shows an example a of a conventional printer configured in this manner.

In the figure, b is the printer body, C, C1,... are photographic paper, d is the paper feed tray, and e is the ink that develops color by being transferred to the photographic paper C, C1, etc. inside the cartridge case f. This is an ink ribbon cartridge that rotatably houses a supply spool h around which an ink ribbon g carrying an ink ribbon g is wound, and a take-up spool i to which the drawn-out end of the ink ribbon g is fixed. ... is loaded into the paper feed section of the printer main body by attaching the paper feed tray d containing it to the tray attachment section j, and the ink ribbon g is loaded by attaching the ink ribbon cartridge e to the cartridge attachment section k. It is loaded into a printing section (not shown) of the printer main body. The printing unit includes a platen roller, a print head, etc., and when the ink cartridge e is installed, the portion between the supply spool h and the take-up spool i of the ink phone g moves the platen roller perpendicularly to its axis. It is positioned so as to cross in the direction. In addition, the print head is placed between a pressure contact position where it is pressed against the platen roller and a standby position where it faces the platen roller with a distance between the platen roller and the intermediate portion that does not impede the movement of the middle part of the ink ribbon cartridge e. is supported so that it can be moved, and is held in a standby position except when printing is performed.

When a print command is given, the photographic paper C is sent out from the paper feed tray d and wound around the platen roller, and then the print head is moved to a pressure position by the driving means and the head portion is pressed against the ink ribbon. g and photographic paper C
In this state, the platen roller rotates to run the photographic paper C, and at the same time, the take-up subroutine i is rotated so that the ink ribbon g runs in synchronization with the photographic paper C. , the ink carried by the ink ribbon g is transferred onto the photographic paper C by the head section, and a print is made.

(CD, Problems to be Solved by the Invention) [Figure 26] (a. Problems with Prior Art) Conventional recording devices of this type, such as the printer a described above, have had the following problems.

That is, loading photographic paper C%c1... and ink ribbon g
Different tasks are required for loading and unloading, and
The photographic papers C%C1... must be stored in the paper feed tray d in advance, and at that time, it is necessary to check the front and back sides of the photographic papers C, C1, etc. and then orient them in the specified direction. There was a problem in that the preparation work required a lot of time and effort.

Furthermore, unless the recording paper and transfer paper used in this type of recording device are compatible with each other, it will not be possible to print, or even if it is possible to print, the print will not be of the original quality. In this respect, since the recording paper and the transfer paper used in the conventional recording apparatus are handled separately, there is a risk that the correspondence between them may be mistaken. In particular, if you store unused recording paper and mix it with other types of recording paper, the next time you use that recording paper, the recording paper and transfer paper will not match. will be carried out.

(b. Attempts to integrate transfer paper and recording paper and its problems) Therefore, we created a single cartridge case with recording paper, a supply spool wrapped with the corresponding type of transfer paper, and a pull-out end of the transfer paper. A cartridge containing a fixed take-up spool (hereinafter referred to as a "transfer paper/recording paper cartridge") is removably installed in the recording device, and the recording device is equipped with a fixed position. Transfer paper attached to
One spool is taken out from the recording paper cartridge and transferred to a position substantially opposite to the transfer paper/recording paper cartridge across the platen roller, so that the transfer paper is loaded so as to pass through a predetermined path in the printing section. I thought about doing it.

In this way, the recording paper and the transfer paper can be easily loaded, and there is no possibility of making a mistake in setting the correspondence between the recording paper and the transfer paper or the orientation of the front and back sides of the recording paper.

However, when such a movement occurs, it is extremely difficult to press the recording paper against the paper feeding means so that the paper feeding means is relatively pressed against the recording paper as the recording paper is loaded. That is, when feeding recording paper to the platen roller, the leading edge of the recording paper stored in the recording paper storage section of the attached transfer paper/recording paper cartridge is pushed up out of the cartridge and into the paper feeding means. It is necessary to provide a push-up means for pressure contact, and the push-up means also requires a drive means to drive it, a control means to control the drive timing, etc., so the mechanical structure and The control circuit becomes considerably complicated, leading to various problems such as increased cost.

(E. Means for Solving the Problems) Therefore, the recording device of the present invention has the above-mentioned y! In order to solve this problem, a recording paper storage section that stores recording paper, a supply spool that has transfer paper wound thereon, and a transfer paper storage section that stores a take-up spool that has a fixed drawing end of the transfer paper are used. Equipped with transfer paper and
To use a recording paper cartridge, take out one spool from the installed transfer paper/recording paper cartridge, transfer it across the platen roller to a position almost opposite to the transfer paper/recording paper cartridge, and then remove the transfer paper. a spool transfer means for loading the recording paper; a print head that performs a printing operation by being pressed against the platen roller via a recording paper and a transfer paper; a head moving means for moving the print head; A paper feeding means for feeding the recording paper, and a push-up arm inserted into the recording paper storage section to press the recording paper against the paper feeding means are provided, and the head moving means and the push-up arm are driven by one driving means. It is something.

Therefore, in the recording apparatus of the present invention, since the head moving means for moving the print head and the push-up arm are driven by one driving means, the head moving means and the push-up arm are driven by separate drive means. The number of motors, etc. can be halved compared to the previous case, and the burden on the control circuit for controlling the sequential operation timing between the movement of the print head and the movement of the push-up arm is reduced, so the mechanical structure The structure of the control circuit is simplified, and the cost can be reduced accordingly. Furthermore, since at least the order of the operation timing is mechanically regulated, the reliability of the operation can be improved.

Since the ink ribbons are always handled as one unit, there is no mistaking the compatibility between them. In addition, if you have unused photographic paper 3.3, etc.,
Since it is sufficient to store the ink ribbon and photographic paper cartridge 2 together, storage is easy and there is no risk of mixing the photographic paper with different types of photographic paper.

(b. Overview of the video printer) [Figures 1 to 6] The video printer 1 (only the main parts of its mechanism are shown in the drawing) is equipped with an ink ribbon and photographic paper cartridge 2 installed in a specified manner. A cartridge mounting mechanism 36 for loading and ejecting the cartridge into a position, a printing section 37 for printing on the photographic paper 3, and supplying the photographic paper 3 to the printing section 37 and removing the photographic paper 3 from the printing section 37. a spool transport mechanism 39 for loading the ink ribbon 4, which takes out the supply spool 5 from the installed ink ribbon/photographic paper cartridge 2 and transports it to a predetermined position, and a take-up spool 6. The ink ribbon running mechanism 40 is configured to run the ink ribbon 4 by rotating the ink ribbon.

The cartridge mounting mechanism 36 is used to removably load the ink ribbon/photographic paper cartridge 2 into the support frame 41 in the front-rear direction (the downward direction in FIG. 1 is the front side, and the upward direction is the rear side). In addition, in the figure, the direction to the left is the left side, and the direction to the right is the right side. In the following explanation of the video printer 1, directions are referred to in this direction.) A movably supported cartridge holder 42 and a moving mechanism 4 for moving the cartridge holder 42.
3 and the ink ribbon/photographic paper cartridge 2 inserted into the cartridge holder 42 into the cartridge holder 4.
Consists of locking levers 44, 44, etc. for fixing to 2,
The ink ribbon/photographic paper cartridge 2 is inserted into and removed from the cartridge holder 42 when the cartridge holder 42 is at the eject position shown in FIG.
This is done in a position close to the cartridge attachment/detachment opening 46a formed in the front wall 46 of the cartridge from the rear. When the ink ribbon/photographic paper cartridge 2 is inserted into the cartridge holder 42, the cartridge holder 42 is initially moved backward by being pressed by the ink ribbon/photographic paper cartridge 2, and while it is moved a predetermined distance. The locking levers 44.44 are engaged with the engagement recesses 26.26 formed in the cartridge case 7, and the cartridge case 7 is fixed to the cartridge holder 42, and the moving mechanism 43 is driven.
The cartridge holder 42 is installed in the mounting position shown in FIG.
It is moved to a position where it is worn.

Then, while the ink ribbon/photographic paper cartridge 2 is being moved toward the mounting position, the i-body 29 is moved to the opening member 47.

The spool transfer mechanism 39 includes two rotatable left and right chuck arms 48, 48, an arm rotation mechanism 49 for rotating the chuck arms 48, 48, and a lock lever 50 supported by one of the chuck arms 48. When the ink ribbon/photographic paper cartridge 2 is installed in the mounting position, the chuck arms 48 and 48 are rotated while holding the supply spool 5, whereby the supply spool 5 is removed from the cartridge case 7. The ink ribbon 4 is then moved to the loading completion position shown in FIG. 4, and the ink ribbon 4 is loaded onto the printing section 37. At this time, the rotation of the supply spool 5 is prevented by the lock lever 50.

The printing unit 37 consists of a platen roller 51 around which the photographic paper 3 is wound and rotates, a thermal print head 52, a head/push-up arm drive mechanism 53 for driving the print head 52 and a push-up arm (to be described later), etc. Until the transfer of the spool 5 to the loading completion position is completed, the print head 52 is in the retracted position shown in FIG. 3 so as not to interfere with the transfer of the supply spool 5.

The paper feed/discharge mechanism 38 includes a paper feed heald 54 and a push-up arm 55 that presses the leading end of the photographic paper bundle 8 against the paper feed heald 54 by pushing up the photographic paper push-up plate 31 in the ink ribbon/photographic paper cartridge 2 attached thereto. It is comprised of various guide members, paper discharge rollers, etc. for guiding the paper feeding path of the photographic paper 3 fed out by the paper feeding belt 54.

Then, when the printing operation is started, the photographic paper 3 is sent out from inside the cartridge case 7 to the printing section 37 by the paper feed/discharge mechanism 38, and is wound around the platen roller 51. The print head 52, which had been in the forward position, is rotated upward and moved to the pressure contact position shown in FIG. From this state, the platen roller 51 is rotated and the ink ribbon 4 is run in synchronization with it, whereby the ink carried by the ink ribbon 4 is transferred to the photographic paper 3 and printing is performed.

The support frame 41 is a member that forms the base of the various mechanisms described above, and includes a bottom plate 41a and two side plates 41b, 41b (hereinafter referred to as "support walls") raised parallel to each other from the left and right side edges of the bottom plate 41a. ), etc., and is fixed inside the outer casing 45.

1 from substantially the front, so that the first guided pin 61.61 is normally in pressure contact with the rear surface of the engagement hole 70.70.

Therefore, when the rotating arm 66.66' rotates in this state, the first guided pin 61.6
1 is pressed substantially in the front-rear direction, thereby moving the cartridge holder 42 in the front-rear direction.

Reference numeral 72 denotes a gear portion formed on the outer peripheral surface of the base portion 67 of the left rotating arm 66 over a range of approximately 180@ in center angle.

44b is located at the front end of the cam groove 65.65, so that the engaging portions 44a, 44a are connected to the cartridge holder
It is held in a non-engaging position located slightly lower than the bottom plate 56 of.

The ink ribbon/photographic paper cartridge 2 is installed by inserting it into the cartridge holder 42 and pushing the cartridge holder 42 backward to some extent by the ink ribbon/photographic paper cartridge 2.

That is, when the ink ribbon/photographic paper cartridge 2 is inserted into the cartridge holder 42, first, the front wall 15 of the main part 14 of the cartridge case 7 comes into contact with the pressed parts 56a, 56a of the cartridge holder 42 and presses them. Since it is pressed rearward, the cartridge holder 42 is thereby moved rearward. While the cartridge holder 42 is moved a predetermined distance in this manner, the locking lever 44.44 is rotated upward by the solenoid guided bin 44b144b being displaced upward by the cam ds65.65. As a result, the engaging portions 44 a, 44 a of the locking lever 44.44 pass through the insertion hole 6.60 of the cartridge holder 42 and are engaged with the engaging recess 26.26 of the cartridge case 7. Thereby, the position of the cartridge case 7 with respect to the cartridge holder 42 is fixed.

Immediately thereafter, the motor 74 is rotated in the normal direction, that is, the worm wheel 76 is rotated clockwise when viewed from the left, and the rotating arms 66, 66' are rotated clockwise. Then, when the rotating arm 66, 66' is rotated approximately 90 degrees clockwise from the initial position, the guided pins 61, 61 and 62 of the cartridge holder 42
．． 62 indicates guide grooves 63 and 63 in which these are engaged separately.

Note that the normal rotation of the motor 74 is stopped after the reduction gear 77 has been rotated counterclockwise to some extent from the above state.
During this time, the gear portion 72 of the left rotating arm 66 disengages from the small gear 77a of the reduction gear 77, and the base 6
The pressed protrusion 67a (see Figure 1) protruding from the outer surface of the reduction gear 77 is pressed by the inclined portion of the pressing cam 77b (see Figure i7) provided on the reduction gear 77, thereby further rotating in the clockwise direction. be done.

Therefore, even after the rotating arm 66, 66' reaches the mounting position of the cartridge holter 42, the rotating arm 66, 66' is rotated clockwise to some extent, so that when the rotating arm 66, 66' stops rotating, the As shown in FIGS. 4 and 7, the rear side of the engagement hole 70.70 of the pivot arm 66.66' is spaced rearwardly from the first guided pin 61.61. 61 is the notch 70a of the engagement hole 70.70, 7
0a, so that the elastic force of the compression spring 71.71 moves the first guided pin 61.61 into the guide groove 63.6.
It acts as a force that presses against the rear edge of 3.

Thus, the cartridge holder 42 is pressed into the mounting position.

The ink ribbon/photographic paper cartridge 2 is installed as described above. In addition, in this state, the left rotation arm 66
The pressed projection 67a is held by coming into contact with the arcuate portion of the pressing cam 77b of the reduction gear 77 (see FIG. 7).

When a command is given to eject the ink ribbon/photographic paper cartridge 2 from this state, the motor 74 reverses and the rotating arms 66, 66' are rotated counterclockwise, thereby holding the cartridge holder. 42 is moved to the eject position and the locking levers 44.44 are returned to the disengaged position just before the cartridge holder 42 reaches the eject position.

Note that 77c is a detection element 7 that is provided on the left side surface of the reduction gear 77 and has a light reflectance significantly different from that of the side surface.
Reference numerals 8a and 78b are reflective photosensors, and the photosensors 78a and 78b are mounted at a distance from each other in the circumferential direction on the upper part of the gear head 73 so as to face the rotation locus of the detection element 77c from the left. The position of the reduction gear 77, in other words, the position of the cartridge holder 42, is detected by a signal consisting of a combination of detection signals from these photosensors 78a and 78b, and the start and stop of rotation of the motor 74 is determined by the above signal. controlled accordingly.

When the ink ribbon/photographic paper cartridge 2 is inserted into the cartridge holder 42, the lower end of the opening member 47.47 is aligned with the groove 27.2 of the cartridge case 7.
7 and the cartridge case 7 begins to press the cartridge holder 42 rearward.At the same time, the lower end of the lid opening member 47.47 comes into contact with both left and right ends of the front end 29a of the lid 29, The lid 29 is pressed relatively forward, thereby moving the lid 29 toward the open position. Then, substantially at the same time as the ink ribbon/photographic paper cartridge 2 reaches the mounting position, the lid 29 reaches the open position, thereby opening the paper feed port 21a of the cartridge case 7.

Further, as the ink ribbon/photographic paper cartridge 2 is moved toward the front of the video printer 1 from this state, the pressure on the lid body 29 by the lid opening members 47 and 47 is released, so that the lid body 29 is moved toward the closed position by the tensile force of the tension springs 30, 30, and the lid body 29 reaches the closed position approximately at the same time as the cartridge holder 42 reaches the eject position.

Therefore, when the ink ribbon/photographic paper cartridge 2 is taken out from the cartridge holder 42, the paper feed port 21
a is occluded.

The supply spool 5 has both ends of the hole 11a of the cylindrical portion 11 connected to the tapered portion 33 of the spool holder 32, 32.
By pressing the outer circumferential surface of 33 a and 33 a, the spool holder 32 and 32 are attached to the protrusion 1 of the cartridge case
6.16 is removed from the cartridge case 7 while being slightly pushed into the inside of the cartridge case 7, and the position in the axial direction after being removed from the cartridge case 7 is the outer flange 12.
12 are defined by being closely opposed to the chuck arms 48 and 48 from the inside, and therefore, in the left and right direction, they are held at substantially the same position as when they are held in the cartridge case 7.

Then, while the supply spool 5 is being transferred toward the loading completion position, the supply spool 5 is prevented from rotating. That is, when the ink ribbon/photographic paper cartridge 2 moves to the mounting position, the lock lever 5
The engaging pawl 50a of o is engaged with the gear part 13 of the supply spool 5 (see FIG. 9(A)), and rotation of the supply spool 5 is prevented, and the supply spool 5 remains prevented from rotating in this manner. The cartridge is taken out from the cartridge case 7. Then, when the chuck arm 48, 48 reaches the position immediately before the loading completion position, the end of the lock lever 50 on the side opposite to the engagement claw 50a comes into contact with the stopper pin 120 and is pressed relatively. Lock lever 5
0 is rotated counterclockwise, and its engaging claw 50a is separated from the gear portion 13 of the supply spool 5 (see FIG. 9).
See B).

Further, when the supply spool 5 reaches the loading completion position, its gear portion 13 is connected to the back tension gear 12.
1, and as a result, an appropriate load is applied by the back tension gear 121.

The supply spool 5 is transferred to the loading completion position as described above.

Therefore, the supply spool 5 is transferred to the loading completion position while being prevented from rotating, so that the ink ribbon 4
is pulled out from the take-up spool 6, and the ink ribbon 4 thus pulled out hits the platen roller 51 from below, and the ink ribbon 4 pulled out from the take-up spool 6 is attached to the leader part or the used is a part,
Therefore, an unused portion will not be pulled out from the supply spool 5.

The ink ribbon 4 thus drawn out is given appropriate tension by applying a load to the take-up spool 6 by the ink ribbon traveling mechanism 40, and is therefore drawn out without slack.

This state is the home position of the video printer 1.

When a command is given to unload the ink ribbon 4 from the home position, the motor 116 is reversed and the arm rotation gears 110 and 110 are rotated counterclockwise. Then, first, the gear portion 13 of the supply spool 5 is separated from the back tension gear 121, and the stopper pin 120 is also relatively separated from the lock lever 50, whereby the lock lever 50 is moved away from the torsion spring 1.
It is returned to the lock position by the elastic force of 12, and its engaging pawl 50a is engaged with the gear portion 13, thereby preventing the supply spool 5 from rotating. Then, when the chuck arm 48.48 reaches a position slightly before reaching the standby position, both ends of the cylindrical portion 11 of the supply spool 5 are fitted onto the holding portions 33.33 of the spool holder 32.32, and thereby, The supply spool 5 is returned to the cartridge case 7, and immediately after this, the stopper portion 107.107 of the rotator 102.102 of IT comes into contact with the arm stopper 119.119, and the chuck arm 48.48 is opened. Reach the standby position.

Therefore, the supply spool 5 is attached to the chuck arm 48.48.
It becomes possible to leave.

During this time, the portion of the ink ribbon 4 that was between the spools 5 and 6 is wound onto the take-up spool 6 by the ink ribbon traveling mechanism described later.

(g, Ink ribbon traveling mechanism) [Fig. 1, Fig. 2, Fig. 7
The coin ribbon traveling mechanism 40 includes a seesaw lever that supports a take-up gear that rotates the take-up spool 6, a sliding lever that rotates the seesaw lever, and a rotating arm 66 that rotates the seesaw lever at a predetermined timing. It consists of an intermediate lever that is pressed by the intermediate lever to move the sliding lever forward, and a drive system that rotates the take-up gear.

Reference numeral 125 designates a seesaw lever, which has a substantially angular shape when viewed from the side and has a recessed portion 125a that opens upward, and is supported by a substantially cylindrical boss portion 125b that protrudes to both left and right sides from an intermediate portion in the front-rear direction. Support pieces 126a, 126 erected on the gear base 126 attached to the bottom plate 41a of the frame 41

A drive system 13 fixed to the left end of 7 and having a motor 131
When the motor 131 rotates, the rotation shaft 127 and the intermediate gear 128 are rotated, and thereby the take-up gear 129 is rotated.

The take-up gear 129 is always rotated clockwise when viewed from the left, and a friction-coupled torque limiter is inserted in the drive system.

Reference numeral 133 denotes a sliding lever, and the sliding lever 133 includes a main lever 134 supported on the left end of the upper surface of the gear base 126 so as to be slidable in the front-back direction, and a main lever 134 that has a constant length in the front-back direction. A sub-lever 135 is slidably supported within a range, and these main levers 134
and a limiter spring 136 compressed between the rear ends of the sub-lever 135, and a connecting pin 137 protruding leftward from the front end of the main lever 134.
An engagement protrusion 125c protruding leftward from a position below the center of rotation of the seesaw lever 125 is slidably engaged with a notch 135a formed on the upper surface of the front end portion of the seesaw lever 125.

This and the gear base 1 are attached to the main lever 134.
The sliding lever 133 is biased with a backward moving force due to the tensile force of a tension spring 138 tensioned between the main lever 134 and the main lever 134. Otherwise, the seesaw lever 125 is held at the rear end position in its movement range (hereinafter referred to as the "retracted position"), and in this state, the seesaw lever 125 moves the ink ribbon with the take-up gear 129 inserted into the cartridge holder 42. The photographic paper cartridge 2 is held at a standby position located at a position slightly lower than the movement locus of the gear portion 13 of the take-up spool 6 of the photographic paper cartridge 2.

When the ink ribbon/photographic paper cartridge 2 moves to the mounting position, a part of the take-up gear 129 relatively passes through the notch 56b of the cartridge holder 42 and the gear insertion notch 25 of the cartridge case 7, and stores the spool. It enters into the chamber 20 and faces the gear portion 13 of the take-up spool 6 from approximately below.

As shown in FIG. 7, the tip of the arm 69 presses the upper end of the intermediate lever 139 to rotate the intermediate lever 139 counterclockwise when viewed from the left. Thereby,
Since the sliding lever 133 is moved forward, the seesaw lever 1
The engagement protrusion 125C of 25 is pressed substantially forward, and the seesaw lever 125 is rotated counterclockwise, whereby the take-up gear 129 is engaged with the gear portion 13 of the take-up spool 6.

The take-up gear 129 is pressed against the gear portion 13 of the take-up spool 6 by the elastic force of the limiter spring 136.

The above-mentioned transfer of the supply spool 5 to the loading completion position is performed from the state where the gear portion 13 of the take-up spool 6 is engaged with the take-up gear 129. The presence of the limiter allows the ink ribbon 4 to rotate as it is pulled out, but a load is also applied to the ink ribbon 4 due to frictional resistance in the torque limiter. Appropriate tension is provided.

Therefore, the take-up gear 129 is connected to the gear portion 1 of the take-up spool 6.
When the motor 131 rotates from the state in which it is engaged with the ink ribbon 3, the take-up spool 6 is rotated in a counterclockwise direction when viewed from the left, that is, in a direction in which the ink ribbon 4 is wound up.

The motor 131 is rotated to rotate the take-up spool 6 when a print command is issued or when an eject command is issued for the ink printer/photographic paper cartridge 2.
During printing, the ink cartridge 4 is connected to the supply spool 5.
It is pulled out from the winding spool 6, and is wound up on the winding spool 6.
At the initial stage of ejection, that is, when the supply spool 5 is returned to the cartridge case 7 from the loading completion position, the portion of the ink ribbon 4 that was located between the supply spool 5 and the take-up spool 6 is attached to the take-up spool 6. It is wound up.

As the cartridge holder 42 is moved toward the eject position, the intermediate lever 13 is moved by the rotating arm 66.
9 is released, the sliding lever 133 is returned to the retracted position by the tensile force of the tension spring 138.
Thereby, the seesaw lever 125 is returned to the standby position.

(h-3-e, rotation of print head, pressure contact with platen)
[Fig. 6, 'tSts diagram] In the initial state, the push-up slider 189, 189 is at the position of the rear wheel in its movement range, and the push-up shaft 188
is the cam groove 192.192 of the push-up slider 189.189
are engaged with the front end portions 192a, 192a of.

When the print head 52 is moved from the retracted position to the forward position, the arcuate curved portions of the pressed pieces 155 and 155 come into contact with the push-up shaft 188 from behind on the road (see Fig. 16(A)). )reference).

Then, when the shaft lock levers 180, 180 lock the moving shaft 161, the driving gears 170 and 1
72 is further rotated forward by a predetermined amount, the pinion tooth portion 1
70d and 172a are meshed with pinion gear 194, 194 to rotate pinion gear 194, 194 counterclockwise when viewed from the left.

As a result, the rack parts 193a, 193a are sent forward, and the push-up sliders 189, 189 are moved forward. Then, the displacement portions 192c, 192c of the cam grooves 192, 192 of the push-up slider 189, 189 move to the push-up shaft 1.
Since both ends of 88 are pressed forward and upward, the push-up shaft 1
88 is displaced upward and the pressed piece 15 of the print head 52
5.155 will be pushed upward. As a result, the print head 52 is rotated counterclockwise about the movement shaft 161 when viewed from the left. and,
When the push-up slider 189, 189 reaches a position slightly forward of the middle of its moving range, both ends of the push-up shaft 188 or the holding edges 192d, 192 of the cam groove 192, 192

After the provided head element (not shown) comes into contact with the platen roller 51, that is, when the print head 52 reaches the pressing position, both ends of the rear push upper shaft 188 or the front end of the pressing edges 196c, 196C of the pressing lever 196.196 The pressing edges 196c, 196c ride on the rear part from the
will be pressed relatively downward.

In this state, the coil springs 199 and 199 are further compressed and the elastic force is applied to the print head 5 through the push-up shaft 188.
2 acts as a force to press the platen roller 51 into contact with the platen roller 51.

As a result, a head element (not shown) of the print head 52 comes into pressure contact with the platen roller 51, and this state is maintained by the elastic force of the coil springs 199, 199 (see FIG. 16(C)).

Immediately after the print head 52 is brought into pressure contact with the platen roller 51, the push-up sliders 189, 189 reach the front end position in their movement range, and at this point the normal rotation of the motor 163 is stopped.

Further, when the motor 163 is reversed from the above-mentioned state, that is, the state where the print head 52 is in pressure contact with the platen roller 51, the pinion gears 194 and 194 are rotated clockwise, and the push-up sliders 189 and 189 are racked. The portions 193a, 193a are sent rearward, thereby causing the push-up sliders 189, 189 to move rearward. Therefore, the push-up shaft 188 first comes off the pressing edges 196c, 196c of the pressing lever 196.196, and the cam groove 192.19
As a result, the print head 52 returns to the standby position by its own weight, and then the push-up shaft 188 moves to the displacement part f92c of the cam groove 192.

Thus, the print head 52 is driven by the drive gears 170, 171.
and 172 are rotated approximately one rotation from the initial position, the drive gears 170, 171 and 17 are moved from the retreat position through the forward position and standby position to the pressure contact position.
2 is rotated counterclockwise about one rotation, it is returned to the retreat position through the standby position and the forward position, and after being moved from the retreat position to the forward position, it is rotated in the front and rear direction before being rotated upward. The position is fixed by the shaft lock levers 180, 180, and the platen roller 51 is in the pressure position.
This kind of sequential control is all done by 1

7a is called the "first tooth part", and the other tooth part 207b
is called the "second tooth". ) is located almost directly above the support shaft 195, and the reversing transmitter 209 is located on its protrusion 209b.
Engagement recess 2 on the front side of the click lock member 211 on the upper side
11a, the click lock is applied, and the clockwise side end of the toothed portion 209a when viewed from the right side is the first toothed portion 207 of the slider moving arm 206.
The slider moving arm 206 is also click-locked, and thereby the arm control slider 200
or is held stably in the forward position.

Therefore, the drive gears 170, 171 and 172 are sequentially rotated by a predetermined amount from the initial position, and the shaft lock lever 18
Immediately after the locking of the moving shaft 161 by 0.0, 180 is completed, the slider tooth portion 172b of the third drive gear 172 moves to the reversing transmitter 2 as shown in FIG. 18(A).
09 and rotates the reversing transmitter 209 clockwise when viewed from the right. Therefore, the stripe moving arm 206 is rotated counterclockwise when viewed from the right, and the arm control slider 200 is moved rearward, and the slider moving arm 206 or its arm 20 is moved backward.
8, the slider tooth portion 172b of the third drive gear 172 is separated from the tooth portion 209a of the reversal transmitter 209, and the rotation of the reversal transmitter 209 and the slider The rotation of the moving arm 206 is stopped, and the arm control slider 200 reaches the retracted position, whereby the push-up arm 55 is rotated upward. This state is the state shown in FIG. 17(B), in which the reversing transmitter 209 is click-locked by being engaged with its protrusion 209b or the engagement recess 211b on the rear side of the click-lock member 211, and the slider Moving arm 206
is prevented from rotating clockwise by the tip of its arm 208 coming into contact with the stepped surface 212a of the click-lock member 212 from behind, and as a result, the push-up arm 55 is prevented from rotating upward. Maintained stably.

Then, when the drive gear 172 is further rotated forward from the above state, the slider tooth 172b is directly engaged with the second tooth 207b of the slider moving arm 206, and thereby the slider moving arm 206 is rotated. The reversing transmitter 209 is rotated clockwise and counterclockwise, respectively, and the arm control slider 200 is returned to the forward position (see FIG. 18(B)). Therefore, the push-up arm 55 is returned to the non-push-up position, and the reversal transmitter 209 is returned to the position where its protrusion 209b is engaged with the engagement recess 211a on the front side of the click-lock member 211.

That is, even if the rotation direction of the drive gear 172 is one direction,
The rotating direction of the slider moving arm 206 is different when the slider tooth portion 172b is engaged with the slider moving arm 206 via the reversing transmitter 209 and when it is directly engaged with the slider moving arm 206. As a result, the direction of movement of the arm control slider 200 is switched.

Also, when the drive gear 172 is rotated in the direction returning to the initial position, the arm control slider 200 is moved back and forth between the forward position and the backward position. That is, when the drive gear 172 is rotated in this direction, the slider teeth 172b first engage with the second teeth 207b of the slider moving arm 206, and the slider moving arm 20
6 in the counterclockwise direction when viewed from the right, the arm control slider 200 is moved to the retracted position, and then the slider tooth portion 172b is rotated via the reversal transmitter 209 to the slider moving arm. 206 first tooth portion 207a
and rotates the slider movement arm 206 in a clockwise direction, thereby returning the arm control slider 200 to the forward position.

The push-up arm 55 is rotated as described above.

Therefore, both the movement of the print head 52 and the rotation of the push-up arm 55 are performed by one head/push-up arm drive mechanism 5.
3 is controlled sequentially.

(i-Print etc.) Printing etc. by the video printer 1 configured as above is performed as follows.

When a print command is issued from the home position state where the loading of the ink ribbon 4 is completed, first, the beginning of the ink ribbon 4 is located. This head positioning is performed by rotating the motor 131 of the ink ribbon traveling mechanism 40 and rotating the take-up spool 6, thereby causing the ink ribbon 4 to travel and detecting the head position display element attached to the ink ribbon 4 using a sensor (not shown). This is done by detecting that the first of the three types of ink layers carried by the ink ribbon 4, that is, the tip of the yellow colored ink layer, is located on the platen roller 51. It is made to come directly below.

Next, the drive gears 170, 171 and 172 are sequentially rotated by a predetermined amount to move the print head 52 from the retracted position to the forward position, and then the moving shaft 161 or shaft lock lever is rotated.
180, 180, and then the arm control slider 200 is moved to the retracted position and the push-up arm 55
is rotated upward, and the stack of photographic paper 8 is brought into pressure contact with the paper feed heald 54.

Here, the forward rotation of the drive gears 170, 171 and 172 is temporarily stopped. That is, it is temporarily stopped in the state shown in FIG. 17(B).

Next, the paper feed heald 54 is run in the forward direction to feed the photographic paper 3, and the leading end of the photographic paper 3 is brought to the platen roller 5.
1, and when this insertion is detected, the platen roller 51 is slightly reversed and the leading end of the photographic paper 3 is fixed by the chuckper 144, and then the drive gears 170, 171 and 172 is further rotated forward to return the arm control slider 200 to the forward position (the state shown in FIG. 18(B)), whereby the push-up arm 5
5 is returned to the non-push-up position.

Then, the paper feed heald 54 is run in the opposite direction for a certain period of time,
Thereby, if two or more sheets of photographic paper have been pulled out, excess photographic paper is returned to the photographic paper storage chamber 19.

Next, the platen roller 51 is rotated in the normal direction and moved to the position at the start of printing, and when it is detected that the platen roller 51 has come to this position, the drive gear 170.1 is turned again.
71 and 172 are sequentially rotated, and the print head 52 is moved from the standby position to the pressure contact position, so that the head elements (not shown) of the print head 52 are brought into contact with the ink ribbon 4.
and is pressed against a platen roller 51 with the photographic paper 3 in between. In this state, the portions of the ink ribbon 4 located front and back across the head portion are in contact with the ribbon guide 158 and guide portion 156 of the print head 52, respectively.

From this state, the platen roller 51 is rotated forward, and the ink ribbon 4 is run in synchronization with the rotation of the platen roller 51, so that the ink in the ink layer 10 is applied to the printing paper in the printing pattern of the image. It is transferred onto the print surface of No. 3.

When printing with one ink layer 10 is completed, the drive gears 170, 171 and 172 are slightly reversely rotated and the push-up sliders 189, 189 are slightly retracted, thereby lowering the print head 52 to the standby position and maintaining this state. Then, the platen roller 51 is moved to the position at the start of printing, and the second ink layer of the ink printer 4, that is, the ink layer 10 colored in magenta, is located, and then the drive gears 170, 171 are moved. and 172 are rotated a little forward, and the print head 52 is again rotated to the platen roller 51.
The photographic paper 3 and the ink ribbon 4 are brought into pressure contact with each other, and the synchronized running of the photographic paper 3 and the ink ribbon 4 is resumed, whereby printing is performed using the ink layer 10. This series of operations is repeated in the same manner to perform printing using the third ink layer 1o. This process results in full-color printing.

When printing is completed as described above, first,
The print head 52 is moved to the forward position, and then the platen roller 52 is reversely rotated and the paper feed belt 54 is run in the forward direction to start discharging the photographic paper 3, which is wrapped around the platen roller 51. The printed photographic paper 3 is guided by a paper flap 93 and passed through a paper discharge path 95, and further,
The paper is transported forward by the paper feed belt 54 and the paper ejection roller 96, passed over the second paper ejection kite 79, and guided to the paper exit.Then, at the same time as the platen roller 51 returns to the initial position, the chuckper 144 is returned to the chuck release position, and the leading end of the photographic paper 3 is released from being fixed to the platen roller 51.

Next, when it is detected that the leading edge of the photographic paper 3 has passed between the paper feed belt 54 and the paper discharge roller 96, the drive gears 170, 171 and 172 are further rotated in the reverse direction, and the arm control slider 200 is moved to the retracted position, whereby the push-up arm 55 is rotated upward and the photographic paper stack 8 or the photographic paper push-up plate 31 is pressed against the paper feed belt 54, and the paper feed belt 54 is moved in the opposite direction. As a result, the photographic paper 3 that has been pulled out in excess is attempted to be returned again.

Then, after a certain period of time has elapsed, the push-up arm 55 is lowered, and then the print head 52 is returned to the retracted position.
