Description

  The present invention relates to a printer device that prints on a recording material such as recording paper based on image information and a cassette or cartridge that is a consumable part thereof.

  2. Description of the Related Art Conventionally, printer devices as computer output devices and digital video output devices can be classified into thermal transfer printer devices, ink jet printer devices, laser printer devices, wire dot printer devices, and the like according to recording methods. Among them, the line thermal transfer type printer device uses an ink sheet and a recording paper, selectively drives a plurality of heating elements arranged in the main scanning direction, and conveys the ink sheet and the recording paper in the sub scanning direction. Thus, printing is performed on the recording paper in the form of dot lines. In recent years, with the progress of input devices that handle images such as digital cameras, digital video cameras, and scanners on the input side, attention has been focused on thermal transfer printer devices. The thermal transfer type printer device is a printer device suitable for printing out electronic image information captured by a still camera or a video camera that records a still image via a computer or a recording medium.

  For example, in other types of printer devices such as an ink jet printer device, there is only a binary selection as to whether or not to form dots, so that an apparent resolution can be obtained by a method such as error diffusion while forming small dots on recording paper. Gradation is obtained. On the other hand, in the case of a thermal transfer printer device, the heat value that can control one pixel can be easily changed, so that a large gradation can be obtained for one pixel. Therefore, there is an advantage that a smooth and high-quality image can be obtained as compared with other printer apparatuses such as an ink jet printer apparatus. Further, since the thermal transfer printer device has improved the performance of the thermal head as a recording means and the performance of the recording paper material, it is possible to obtain an image print that is not inferior to a silver salt photograph even in the finished quality. As a result, in order to keep pace with recent advances in digital cameras, it has attracted particular attention as a printer for natural images.

  Furthermore, a system that directly prints out without connecting a thermal transfer printer device to an imaging device such as a digital camera or a digital video camera has appeared. Alternatively, there is a system in which a thermal transfer printer device and an imaging device are integrally configured to directly print out captured image information without using a device such as a computer for processing image information. According to such a system, image information from a digital camera or a digital video camera can be easily photographic-printed, and the degree of attention to a thermal transfer printer device is increasing. However, in order to perform full-color printing in the thermal transfer method, it is necessary to repeatedly transfer inks of a plurality of colors, and a general configuration for realizing this will be described below.

  FIG. 33 shows a first example of a general configuration of a conventional thermal transfer printer. As shown in FIG. 5A, only the uppermost recording paper P is separated and fed from the recording head P and the platen roller 105 by the paper feeding roller 108 and the separating means 109. It is conveyed between. An ink sheet 106 is disposed between the thermal head 104 and the recording paper P. The recording sheet P is wound around a platen roller 105 having an outer periphery slightly longer than the entire length of the recording sheet P, and the ink sheet 106 and the recording sheet P are pressed against each other by the thermal head 104 and the platen roller 105. Then, the printing operation is performed by rotating the platen roller 105 while the ink on the ink sheet 106 is thermally transferred onto the recording paper P by the heat generated by the thermal head 104. In order to perform the printing of the next color after the printing of the first color, the thermal head 104 is released from pressure and the platen roller 105 is rotated to reach the printing start position as shown in FIG. The recording paper P is advanced, and the second and subsequent colors are printed by the same operation as the first color. In this way, full-color printing is performed by superimposing three colors of yellow, magenta, and cyan.

  A second example of the general configuration of a conventional thermal transfer printer is shown in FIG. As shown in FIG. 6A, only the uppermost recording paper P is stacked and fed to the thermal head 204 and the platen roller 205 by the paper feed roller 202 and the separation unit 203. Is done. The ink sheet 206 and the recording paper P are pressed against each other by the thermal head 204 and the platen roller 205. Then, the recording paper P is transported by a pair of capstan rollers 207 and a pinch roller 208 provided downstream in the printing direction while the ink on the ink sheet 206 is thermally transferred onto the recording paper P by the heat generated by the thermal head 204. The printing operation is performed. In order to perform printing of the next color after the printing of the first color is completed, the press contact of the thermal head 204 is released as shown in FIG. Then, the capstan roller 207 and the pinch roller 208 are rotated in the reverse direction to the printing operation, the recording paper P is returned to the printing start position, and the second and subsequent colors are printed in the same operation as the first color. In this way, full-color printing is performed by superimposing three colors of yellow, magenta, and cyan.

  In both the example of FIG. 33 and the example of FIG. 34, the recording paper and the ink sheet in the paper cassette are consumables and need to be replaced / supplied according to use. Here, the ink sheet is generally supplied to the user by a cartridge in which both ends of the ink sheet are wound around two bobbins and the two bobbins and the ink sheet are housed in a frame. Reference numeral 110 in FIG. 33 and reference numeral 210 in FIG. 34 indicate the frame of the cartridge. The cartridge has a gap as indicated by reference numeral 110a in FIG. 33 and reference numeral 201a in FIG. When the cartridge is mounted on the printer, the cartridge is guided and mounted at a predetermined position so that the thermal heads 104 and 204 provided in the printer body are accommodated in the gaps 110a and 201a of the cartridge.

  The above two methods are common in the past. In the first example, a platen roller having an outer periphery slightly longer than the entire length of the recording paper P is required, so that the apparatus becomes large. A mechanism for winding and holding the recording paper around the platen roller is not shown in FIG. There is a demerit that the apparatus becomes complicated because it is necessary. However, since the second color printing start portion is located immediately after the first color printing is completed, there is an advantage that the time for returning the recording paper is not required as in the second example, and the printing time can be increased. On the other hand, the second example has a demerit that the printing time is extended, but has an advantage that the apparatus can be easily downsized and simplified.

  However, in the above-described thermal transfer type printer device, in order to obtain a good print, it is necessary to use a dedicated paper having a surface on which ink is easily transferred as a recording paper. For this reason, for example, an ink cartridge containing ink sheets for 50 recording sheets and 50 recording sheets are sold as a set. As a result, the user must unpack the recording paper and ink cartridges sold as a set, load the ink cartridge into the main unit, and load the recording paper into the paper cassette. It was.

  In the case of a thermal transfer printer, as shown in FIG. 35, it is less wasteful to prepare different ink sheets according to recording paper of a predetermined size. Therefore, for example, an A6 size recording paper and an ink cartridge storing an A6 size ink sheet are sold as a set, and an A7 size recording paper and an A7 size ink sheet are stored as a set. Sold. Users purchase according to their usage. When A7 size printing is performed after A6 size printing is performed, the A6 size recording paper and the A6 size ink cartridge are taken out. Instead, the A7 size recording paper and the A7 size ink cartridge are removed. Is loaded. At this time, the taken A6 size recording paper and the A6 size ink cartridge need to be stored for later use. In this case, the ink cartridge and the recording paper are separated from each other, and the recording paper and the ink cartridge are not suitable for dust and direct sunlight, so that they have to be stored in a storage bag or the like.

  As proposals for solving these annoyances, as in Patent Documents 1 and 2, a cartridge (referred to as a cassette in Patent Document 2) in which an ink sheet and recording paper are integrally stored is proposed.

  However, although the thermal transfer printer disclosed in Patent Document 1 integrates the ink sheet storage portion and the recording paper storage portion, it cannot perform a printing operation while the ink sheet is still stored in the cartridge. . Therefore, in order to perform the printing operation, a mechanism for taking out the ink sheet from the cartridge and loading it to the printing position is necessary, and there is a problem that the apparatus becomes complicated by that mechanism and the reliability is lowered.

  What has improved this problem is the thermal transfer printer disclosed in Patent Document 2. In this proposal, it is not necessary to load the ink sheet to the printing position after the integrated cartridge is stored in the main body, and the printing operation can be performed in the stored state. In addition, the user does not feel bothered to install the ink sheet and recording paper separately in the printer device or to store the removed ink sheet and recording paper separately when using different types of recording paper. ing. However, when photographic printing is the primary purpose, the paper used needs to have a predetermined thickness in order to ensure its storage stability, durability, or print quality. Therefore, if the paper is extremely bent during conveyance for printing, scratches or wrinkles may occur on the stamp screen. Further, when the recording paper is thick, depending on the separation method for separating one recording paper from the cartridge, if there is not enough space for the recording paper to be bent at the time of separation, the reliability of separation is lowered. In the paper disclosed in Patent Document 2, the paper transport path is formed on the outer peripheral surface of the cartridge. However, it is slightly large so as not to cause extreme bending in order to suppress damage to the paper and increase the transport reliability. The outer shape of the cartridge is formed by the radius R. However, the inside of the arc shape is a useless space to form this transport path. Further, in order to make the conveyance path bend smoothly, the thickness direction of the cartridge is required to some extent, and there is a limit to downsizing. Eventually, the cartridge becomes larger than the minimum size required for storing the paper and the ink sheet, which leads to an increase in the size of the printer main body.

Patent Document 3 discloses a configuration in which the distance between the separation claw and the pickup roller is kept constant even when the paper size is different, in order to improve the separation reliability of the claw separation method. . According to this method, the amount of engagement between the separation claw and the paper is always constant, and the reliability of separation can be ensured. However, this method has a complicated mechanism, increases the size, and increases the cost.
Japanese Patent No. 2523355 JP 2000-108442 A JP-A-8-319036

  In view of the above-described problems, an object of the present invention is to provide a cassette provided with a separation claw with high recording sheet separation reliability.

  In particular, when paper is fed by the nail separation method, the size tolerance of the paper is affected, and there is a difference in the length in the width direction of the portion in contact with the two nail recording papers at both ends of the paper. There are problems such as reduced reliability and wrinkles generated during separation. It is to solve such a problem.

The configuration of the present invention for achieving the above object is as follows.
A recording paper storage section for storing recording paper;
A first separation claw and a second separation claw for separating the recording paper, which are disposed so as to be engaged with both corner portions at the leading end of the recording paper in the recording paper feeding direction;
A regulating member that regulates the position of one end of the recording paper stored in the recording paper storage unit;
Biasing means for biasing the recording paper so as to abut against the regulating member,
Of the first and second separation claws, the first separation claw closer to the regulating member is a cassette formed smaller than the second separation claw.

  According to the present invention, when paper is fed by the nail separation method, even if a recording paper manufacturing error occurs, the difference in the length in the width direction of the portion where the separation claw is in contact with the recording paper is minimized, Separation reliability can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  Based on FIG. 1 and FIG. 2, the configuration of an embodiment of the recording paper ink sheet integrated cartridge in the present invention will be described. The recording paper / ink sheet integrated cartridge is a cartridge that is integrated with a recording paper storage portion for storing recording paper and an ink sheet storage portion for storing ink sheets, and is a cartridge that is detachable from the printer body. .

  The recording paper / ink sheet integrated cartridge 1 of the present embodiment shown in FIG. 1 includes an ink sheet storage portion between an upper case 10 that forms a recording paper storage portion that mainly stores and stores recording paper, and the upper case 10. The lower case 11 is formed. The ink sheet storage unit includes a supply side storage unit 20 (first storage unit) that stores an ink sheet before printing, and a winding side storage unit 21 (second storage unit) that stores an ink sheet after printing. Form.

  On the bottom surface of the cartridge 1, a feeding port 30 for taking out recording sheets one by one from the cartridge is formed. The feeding port 30 is adjacent to the supply-side storage unit 20 and forms a substantially rectangular opening at the end of the recording paper storage unit over the entire length of the recording paper. Separating claws 31 and 32 for separating recording sheets one by one are provided at both ends of the feeding port 30. The upper case 10 and the lower case 11 are injection-molded plastics, thereby reducing costs.

  FIG. 2 is a cross-sectional view in a direction perpendicular to the axial direction of the take-up shaft of the ink sheet.

  In FIG. 2, a band-shaped ink sheet 12 is stored in an ink sheet storage portion formed between an upper case 10 and a lower case 11. The first bobbin 12 a is disposed in the supply side storage unit 20 of the ink sheet storage unit, and the second bobbin 12 b is stored in the winding side storage unit 21. The ink sheet 12 is wound around the first bobbin 12a, and the tip is attached to the second bobbin 12b for winding by adhesion or the like.

  In the recording paper storage unit 22 of the upper case 10, the recording paper 13 is stacked and stored in the same number as the number of sheets that can be printed with the ink sheet 12. For example, if 50 sheets of the ink sheet 12 are wound up, 50 recording sheets 13 are also stored. That is, in the recording paper / ink sheet integrated cartridge in the present proposal, for example, when printing for 50 screens is finished, the recording paper and the ink sheet are used at the same time, and only one of them does not finish using first. Therefore, only one of the cartridges is not replenished or replaced. When the user has finished using the cartridge, the user needs to replace the entire cartridge, and the labor of replacement can be saved.

  The cartridge 1 has an upper surface opening 200 when the recording paper 13 and the protective sheet 14 are assembled into the upper case 10. The upper surface opening 200 is an opening for applying pressure from the upper surface opening 200 when the cartridge 1 is loaded in the printer and a printing operation is performed.

  The protective sheet 14 is a protective sheet for preventing the recording paper 13 from being soiled and scratched. The outer shape of the protective sheet 14 is substantially the same as that of the recording paper 13, and recording is performed in a state where the recording paper 13 is stacked on top of the recording paper 13. It is stored in the paper storage unit 22. As shown in FIG. 2, there is a space 33 between the ink sheet supply side 20 and the take-up side storage 21 and between the ink sheet 12 and the recording paper 13. This is a space where a head unit, which will be described later, is located when the cartridge is loaded into the printer. In addition, an opening 34 (second opening) is provided in the middle of the supply side storage portion 20 and the winding side storage portion 21 of the upper case 10. The opening 34 extends over almost the entire area of the recording paper storage unit 22 in the longitudinal direction, and is connected to a side opening 34a (first opening) formed on one of the two side surfaces of the upper case 10, as shown in FIG. ing. The side opening 34a is provided on the leading side when the cartridge 1 is loaded into the printer.

  As shown in FIG. 1, a first positioning hole 35 is provided in the end surface of the ink sheet supply side storage portion 20, and a second positioning hole 36 is also provided in the vicinity of the end surface of the winding side storage portion 21. These positioning holes 35 and 36 are fitted with a positioning shaft on the printer body side when the cartridge 1 is loaded in the printer, and the position of the vicinity of the winding shaft of the ink sheet is regulated to stabilize the running and winding of the ink sheet. This is to make it easier.

  Further, in the vicinity of the end face of the take-up side storage portion 21, a cartridge discrimination projection 37 having a different shape depending on the type of cartridge is formed. The cartridge discriminating projection 37 changes the projection shape according to the size of the recording paper or the type of the ink sheet, and the printer main body discriminates this and determines the recording paper or the recording paper according to the type of the ink sheet. This is for controlling conveyance and printing.

  The type of cartridge will be described with reference to FIGS. FIGS. 15 and 16 show three types of cartridges having different recording paper sizes. FIGS. 15 (a), (b), and (c) show a post size (Psize) and an L size (Lsize), respectively. ), A card size (Csize) cartridge. 16 is a cross-sectional view of the supply-side storage unit 20 as viewed from the feeding port 30 side of FIG. As shown in FIGS. 15 and 16, the size of the recording paper storage unit 22 of the upper case 10 varies depending on the size of the recording paper 13, and is the same in the direction orthogonal to the ink sheet winding axis. Dimension. Further, the portion that mainly stores the ink sheet 12 formed by the lower case 11 has the same dimension D in the ink sheet take-up axis direction regardless of the size of the recording paper, and the same dimension in the direction orthogonal to the ink sheet take-up axis. Yes. The positioning holes 35 and 36 described above are provided on the end face of the ink sheet storage portion, and the cartridge discrimination projection 37 is also provided on the end face of the ink sheet storage portion. Furthermore, as shown in FIG. 16, the width of the ink sheet 12 differs depending on the size of each recording sheet, but the total length of the shaft around which the ink sheet 12 is wound is also set to be the same.

  Next, an assembly method of the recording paper / ink sheet integrated cartridge 1 will be described in order with reference to FIGS. 3, 4, 5, and 6. FIG.

  First, as shown in FIG. 3, the first bobbin 12 a and the second bobbin 12 b of the ink sheet 12 are respectively placed in the semicircular cut 10 b of the upper case 10 with the recording paper storage portion 22 of the upper case 10 facing down. And drop into the U-shaped cut 10c. The lower case 11 is assembled into the upper case 10 from above, and the claw 10a of the upper case 10 is engaged with the hole 11b of the lower case 11, and the claw 11ba of the lower case 11 is engaged with the hole 10d of the upper case 10. Thus, the upper case 10 and the lower case 11 are joined. Although not visible in FIG. 3, similar claws and holes are arranged in the rear of the figure, and the main parts of the upper case 10 and the lower case 11 are fixed to each other. Further, in the recording paper / ink sheet integrated cartridge of this embodiment, the welding shaft 80 provided in the upper case 10 and the welding hole 81 provided in the lower case 11 are coupled by thermal welding. Details will be described with reference to FIGS. 4A shows a state in which the ink sheet 12 and the lower case 11 shown in FIG. 3 are assembled to the upper case 10, and the welding shaft 80 of the upper case 10 is welded to the lower case 11 in this state. It penetrates the hole 81. In this state, the tip of the welding shaft 80 is deformed by pressing the terminal 82 of the welding tool against the tip of the welding shaft 80 with a predetermined load. As a result, the outer diameter of the welding shaft 80 becomes larger than the welding hole 81 as shown by reference numeral 80a in FIG. 4B, and the upper case 10 and the lower case 11 are in close contact with the lower case 11 from above. Are surely combined. Since the tip shape of the terminal 82 of the welding tool shown in FIG. 4 is a spherical concave shape, the deformed shape 80a of the welding shaft 80 is a spherical convex shape. However, if the tip of the terminal 82 is flat, the welding shaft 80 is deformed into a flat shape, and the same effect can be obtained in this case. Further, the terminal 82 may be either a terminal provided with a heater or a terminal that generates heat by vibrating the welding shaft 80 by ultrasonic vibration. At this time, since the tip of the welding shaft 80 before deformation has a conical shape, it is easy to cause deformation from the conical tip in any case.

  Further, the storage of the recording paper 13 and the protective sheet 14 will be described with reference to FIGS. After the ink sheet 12 and the lower case 11 are assembled to the upper case 10, 50 corners of the recording paper 13 and one protective sheet 14 are stacked, and the corner from the upper opening 200 to the recording paper storage portion 22 of the upper case 10. It inserts into the back side of the holding | suppressing part 10e of 2 parts from diagonally. At this time, the recording paper 13 is not dropped from the feeding port 30 by the two separation claws 31 and 32 provided at the corner portion of the feeding port 30. After the recording paper 13 and the protective sheet 14 are loaded into the upper case 10, the pressing members 15 and 16 are attached to the remaining two corner portions of the upper case 10 as shown in FIG. 6. As a result, the recording paper 13 does not fall out of the recording paper storage unit 22 because four corners are held. The holding members 15 and 16 are also made of resin, and are attached to the upper case 10 by claws using elastic deformation of the resin. As described above, the recording paper / ink sheet integrated cartridge of the present embodiment mainly accommodates the recording paper and the ink sheet with the two parts of the upper case 10 and the lower case 11 and is reduced in size without requiring many parts. Can also be achieved.

  Next, a printer using the recording paper ink sheet integrated cartridge 1 of the present embodiment will be described with reference to FIG. FIG. 7 shows a state in which the door 41 on the side surface of the printer main body 40 is opened, and the cartridge insertion opening 42 is exposed. The cartridge insertion opening 42 is substantially the same shape as the cross-sectional shape of the cartridge 1 and is a slightly larger opening. The end of the head unit 45 is visible in the cartridge insertion opening 42. FIG. 8 shows a state where the cartridge 1 is inserted into the cartridge insertion opening 42. As shown in FIG. 8, when the cartridge 1 is inserted into the printer body, the tip of the head unit 45 is slightly exposed from the opening 15 of the cartridge 1, and the shaft 46 at the tip of the head unit 45 protrudes from the cartridge 1 by a predetermined amount. It will be in the state. When the door 41 is closed in this state, the engagement hole 41a provided in the inner surface of the door 41 is fitted into the shaft 46, and the tip position of the head unit 45 is restricted, so that the printer can be used.

  Reference numeral 50 denotes an urging member for urging the recording paper in the cartridge in the direction of the arrow in the drawing. The urging member 50 has a distal end fitted into the shaft 48 a and is held at the other end by a rail 51 fixed to the head frame 55 so as to be slidable in the cartridge attaching / detaching direction. It is energized.

  Further, a photo reflector 53 for detecting the presence or absence of recording paper in the cartridge is attached to the head unit 45 by a holder 54. FIG. 10 shows a cross-sectional view of the photo reflector 53 attached. As shown in FIG. 10, the light projecting portion and the light receiving portion of the photo reflector 53 are attached to the head unit 45 upward, and are fixed by covering with a holder 54 from above.

  Returning to FIG. 9, reference numerals 56 and 57 indicate a first positioning axis and a second positioning axis for positioning the cartridge 1 when the cartridge 1 is loaded in the printer main body. When the cartridge 1 is loaded into the main body, the cartridge 1 is fitted into a first determining hole 35 and a second positioning hole 36 (FIG. 1) provided in the cartridge 1 to regulate the position of the cartridge 1 in the printer main body. Is.

  Reference numeral 58 denotes a cartridge discrimination switch for discriminating the type of cartridge. This cartridge type is determined by the protrusion 37 (FIGS. 1 and 15) provided on the cartridge 1 when the cartridge 1 is loaded in the printer body. It is to be determined.

  Reference numeral 59 denotes a winding shaft that engages with the second bobbin 12b (FIGS. 2 and 3) of the cartridge 1 when the cartridge 1 is loaded in the printer body, and drives the ink sheet 12 to wind up during printing. The winding shaft 59 is connected to the gears 59a and 59b and is controlled to rotate at a predetermined speed during the printing operation. Reference numeral 60 denotes a driven shaft that rotates when the ink sheet 12 is wound up. This is for detecting, for example, a rotation operation and checking whether the ink sheet 12 is reliably supplied.

  The head unit 45 described above is installed in the printer main body 40, and the state in which the cartridge 1 is loaded into the head unit 45 will be described with reference to FIGS. 11, 12, and 13. FIG. The cassette 1 is loaded into the head unit 45 in the printer main body 40 in the direction of the arrow in FIG. At this time, the head unit 45 enters the space 33 between the ink sheet 12 and the recording paper 13 shown in FIG. FIG. 12 is a view of this state as seen from the back side of the cartridge 1. As shown in FIG. 12, the head unit 45 is in a space 33 above the ink sheet 12 and below the recording paper 13.

The winding shaft 59 is fitted to the second bobbin 12b, and the driven shaft 60 is fitted to the first bobbin 12a. Further, the cartridge discrimination switch 58 is pressed by the cartridge discrimination projection 37.

  Since the positioning holes 35 and 36 and the cartridge discriminating protrusion 37 are in the same position even when the types of cartridges are different, there is no need to provide a plurality of positioning shafts 56 and 57 and cartridge discriminating switches 58 on the printer main body 40 side. Further, since the overall length and arrangement of the first bobbin 12a and the second bobbin 12b are the same, it is not necessary to vary the overall length, position, etc. of the winding shaft 59 and the driven shaft 60. In this way, even if the cartridge has a plurality of recording paper sizes or a cartridge having a plurality of ink sheet 12 sizes, the configuration inside the printer main body can be simplified by making the outer dimensions of the ink sheet storage unit the same. Can do. That is, the internal configuration of the printer main body is simplified by making the outer shape of the ink sheet storage unit, the positions of the positioning holes 35 and 36, and the cartridge discriminating projection 37, and the overall length of the first bobbin 12a and the second bobbin 12b common. can do.

  FIG. 17 shows a state in which the cartridge 1 is completely loaded in the printer main body 40, and the recording paper 13 and the protective sheet 14 are not shown for easy understanding. As shown in FIG. 17, a paper feed roller 48 and a photo reflector 53 are located in the opening 34 of the upper case 10. Further, the urging member 50 provided in the head unit is located inside the side opening 34a.

  FIG. 18 is a cross-sectional view showing the positional relationship between the urging member 50, the cartridge 1, and the recording paper 13.

It is in contact with the end face of. In this abutting state, the urging member 50 does not abut against the outer side surface of the upper case 10 and has a gap w, so that the recording paper 13 is surely shifted rightward in the figure (in the direction of the cartridge insertion opening 42). .

  The inclined surface 50b provided on the urging member 50 is a contact surface on which the recording paper 13 is sequentially fed from the lowermost recording paper in the figure and the recording paper 13 moving from the upper side to the lower side in the figure is not caught. It guides to 50a.

  Next, the operation of the urging member 50 will be described.

  20 (a) and 20 (b) are simplified diagrams for easy understanding of the relationship between the separation claw and the recording paper in the example of the cartridge when the urging member 50 is not employed. 20A, reference numeral 100 denotes an upper case, reference numerals 101 and 102 denote separation claws, and reference numeral 103 denotes a recording paper. Both corners at the leading end of the recording paper 103 in the feeding direction are the separation claws 101 and 102, respectively. 102 is in contact. In general, recording paper has an error when it is cut, so there is a tolerance in the vertical and horizontal dimensions. The inner dimension L1 of the recording paper storage portion of the upper case 100 needs to be a dimension with a gap even with respect to the upper limit (Lmax) of the longitudinal dimension of the recording paper. Therefore, when the dimension L in the direction (width direction) orthogonal to the recording paper feeding direction is a tolerance lower limit, the gap becomes large. FIG. 20B shows a state in which the width direction dimension L is a recording sheet having a dimensional tolerance lower limit (Lmin) and the recording sheet is shifted to the right side in the drawing in the cartridge 100. In this case, the width direction length X1 of the portion where the right separation claw 101 is in contact with the recording paper 103 and the width direction length X2 of the portion where the left separation claw 102 is in contact with the recording paper 103 are greatly different. End up. For example, as shown in FIG. 20B, when the tolerance of the longitudinal dimension L of the recording paper is ± 0.5 mm, the dimensional difference between the recording paper with the upper limit of dimension tolerance (Lmax) and the recording paper with the upper limit of dimension tolerance (Lmin). Is 1.0 mm. Further, when the margin of the inner dimension of the cartridge 100 is set to 0.1 mm on each side, a gap of 1.2 mm is generated on a recording sheet having a dimensional tolerance lower limit (Lmin). Therefore, the difference between the lengths X1 and X2 in the width direction of the portion where the separation claws 101 and 102 are in contact with the recording paper is 1.2 mm.

  There is no problem if the width direction length of the portion where the separation claw is in contact with the recording paper is large enough to ignore this difference. However, when using a recording paper having a size and quality that prints a photograph, it is not possible to use a large separation claw considering the load of separation driving and damage to the recording paper. Therefore, it is difficult to use a separation claw with a size that can ignore the difference of 1.2 mm, and the difference in separation timing increases when the recording paper performs the separation operation. In the worst case, separation cannot be performed. It will cause defects.

  Hereinafter, the cartridge 1 adapted to the urging member 50 (side-shifting member) according to the present invention will be described with reference to FIGS. 19 (a), 19 (b), and 19 (c). This is also a simplified diagram for easy understanding of the relationship between the separation claw and the recording paper. 19A, 19B, and 19C are views seen from the feeding port 30 side of the cartridge 1, showing the relationship between the recording paper 13 and the separation claws 31, 32, and the leading edge of the recording paper 13 in the feeding direction. Corner portions are hooked on the separation claws 31 and 32. FIG. 19A shows a case where the longitudinal dimension L of the recording paper is the upper limit (Lmax) of the tolerance. At this time, the longitudinal dimension L1 of the recording paper storage portion of the upper case 10 is set so that it can be stored with a margin even when the longitudinal dimension L of the recording paper 13 is the upper limit of the tolerance. In this example, when the longitudinal dimension L of the recording paper 13 is the upper limit of tolerance, the recording paper 13 is set to a dimension that allows a 0.2 mm gap as shown in FIG.

  FIG. 19B shows the case where the longitudinal dimension L of the recording paper is the nominal dimension, and FIG. 19C shows the case where the longitudinal dimension L of the recording paper is the lower limit of tolerance (Lmin). In each of FIGS. 19A and 19B, the left direction is the loading direction of the cartridge 1, and the right direction is the direction in which the cartridge 1 is removed from the printer main body. Therefore, the recording paper 13 is biased from the left to the right as viewed in the figure by an urging member 50 (a biasing member) (not shown), and abuts against the right inner wall 10a (the regulating member) toward the upper case 10. ing.

  As shown in FIG. 19B, when the longitudinal dimension L of the recording paper 13 is a nominal dimension, the separating claws 31 and 32 are in contact with the offset recording paper 13. The separation claw 31 is set larger than the separation claw 32 so that the width-direction lengths X1 and X2 of the portions are equal. Since the sizes of the separation claws 31 and 32 are set in this way and the recording paper 13 is shifted toward the separation claw 32, the separation claw 31 when the longitudinal dimension L of the recording paper 13 varies within the tolerances, The difference between the lengths X1 and X2 in the width direction of the portion 32 in contact with the recording paper 13 is equal to or less than the tolerance of the longitudinal dimension L.

  For example, as shown in FIG. 19A, the separation claw 31 records with respect to the width direction length amount X1 of the portion where the separation claw 32 is in contact with the recording paper when the recording paper tolerance upper limit (Lmax) is reached. The width-direction length X2max of the portion in contact with the paper increases by the tolerance of the longitudinal dimension L of the recording paper 13. For example, if the tolerance of the longitudinal dimension L is ± 0.5 mm, X2max is larger than X1 by 0.5 mm.

  On the other hand, when the tolerance is the lower limit (Lmin), the width direction length X1 of the portion of the separation claw 32 in contact with the recording paper is smaller than the length X1 of the portion of the separation claw 32 in contact with the recording paper. The length X2min is reduced by the tolerance of the width direction dimension L of the recording paper 13. As a result, the length X2min in the width direction of the portion where the separation claw 31 is in contact with the recording paper is smaller by 0.5 mm than the length X1 in the width direction of the portion of the separation claw 32 in contact with the recording paper. Become.

  In the case where the urging member 50 (one-sided member) was not employed, a difference in length in the width direction of the portion where the separation claw contacted the recording paper was 1.2 mm on the left and right. On the other hand, when the urging member 50 is employed, the difference in the length in the width direction of the portion where the separation claw contacts the recording paper can be suppressed to a dimensional tolerance of 0.5 mm. The difference in the length in the width direction of the part of the separation claw that contacts the recording paper at the left and right corners can be minimized, and the separation timing difference is reduced when the recording paper performs claw separation. It is possible to suppress the occurrence of defects such as inability to do so.

  FIG. 32 shows the sizes of the left and right separation claws 31 and 32. The recording paper 13 is pressed against the regulating member 10 a by the urging member 50. The first separation claw 32 on the regulating member 10a side is smaller than the second separation claw 31 on the opposite side.

  The length A1 in the direction (width direction) orthogonal to the feeding direction of the first separation claw 32 is shorter than the length A2 of the second separation claw 31 in the width direction.

A1 <A2
The length B1 of the first separating claw 32 in the feeding direction is shorter than the length B2 of the second separating claw 31 in the feeding direction.

B1 <B2
Further, the area of the surface of the first separation claw 32 facing the recording paper 13 is smaller than the area of the surface of the first separation claw 31 facing the recording paper.

(A1 × B1) / 2 <(A2 × B2) / 2
Next, based on FIGS. 21 to 27, the operation of the printer apparatus in which the recording paper ink sheet integrated cartridge 1 of the present embodiment is mounted will be described. FIG. 21 shows a standby state before printing in which the cartridge 1 is loaded in the printer main body 40. Reference numeral 60 denotes a pressure plate, which presses the recording paper 13 toward the paper feed roller 48 when paper is fed. In the state shown in FIG. 21, since the print standby state is set, the pressure plate 60 is located away from the recording paper 13. From this state, the pressure plate 60 moves downward in the figure and is pressed from the upper surface opening 200 to the recording paper 13 with a predetermined pressure. When the paper feed roller 48 rotates counterclockwise, only one sheet of recording paper 13 in contact with the paper feed roller 48 moves to the left in the figure, nail separation is performed, and recording is performed from the feed port 30. Paper 13 is fed.

  FIG. 22 shows a state in which the fed recording paper 13 is fed out from the cartridge 1 by a predetermined amount.

  As shown in FIG. 22, the recording paper 13 bends along the supply side storage portion (first storage portion) 20 of the ink sheet 12 and exits from the feeding port 30. The recording paper 13 is a paper suitable mainly for photographic printing. If it is bent extremely, scratches, wrinkles, etc. will occur on the printing screen, but as shown in the figure, on the left side of the supply side storage section 20. And it can bend gently in the space D below the feeding port 30. Further, since the paper feed roller 48 can be driven near the approximate center of the recording paper 13, it is possible to secure a sufficient length that allows the recording paper 13 to bend. As a result, the reliability of separation is improved, and the recording paper 13 is not significantly bent, and damage to the recording paper 13 can be minimized. This is because the take-up side storage portion (second storage portion) 21 of the ink sheet is arranged along the right side of the recording paper storage portion 22 in the drawing, so that the space D can be secured. ing.

  Further, since the paper feed roller 48 is installed in the head unit 45, the apparatus can be reduced in size, and an upper surface opening 200 for loading and pressurizing the recording paper 13 is provided on the side facing the paper feed roller 48. Therefore, pressurization can be performed efficiently.

  After the recording paper 13 is fed out by a predetermined amount, the recording paper 13 is pressed against the first roller 62 by the roller plate 61 as shown in FIG. 23 and is further pulled out from the cartridge 1 by the rotation of the first roller 62. FIG. 24 shows a state in which one sheet of recording paper 13 is completely pulled out from the cartridge 1 and fed by a predetermined amount. From this state, the recording paper 13 is rotated about an axis perpendicular to the surface of the recording paper 13. FIG. 25 shows a state during the rotation. The rotation of the recording paper 13 is performed by rotating both the two first rollers 62a and 62b in the reverse direction. The first roller 62a is rotated in a direction for drawing the recording paper 13 into the printer main body 40, and the first roller 62b is rotated in a direction for feeding out the printer main body 40. FIG. 26 shows a state in which this rotational driving is completed. From this state, the recording paper 13 is fed into the printer main body 40 by the first rollers 62a and 62b, and the printing operation is started.

  The roller plate 61 and the rollers 62a and 62b used for transporting the recording paper 13 described above are also preferably arranged in the space D described above with reference to FIG. Further, since the recording paper feeding port 30 is provided outside the ink sheet supply side storage section 20 on the upstream side of the conveyance path during printing, the recording paper 13 can be smoothly transferred to the printing conveyance, and is wasted. Will not be transported.

  FIG. 27 shows the printing state of the recording paper. In the printing operation, first, the ink sheet 12 and the recording paper 13 are pressed against each other by the thermal head unit 45 and the platen roller 64. Then, while the ink on the ink sheet 12 is thermally transferred onto the recording paper 13 by the heat generated by the thermal head unit 45, the recording paper 13 is conveyed by a pair of capstan rollers 65 and a pinch roller 66 provided downstream in the printing direction. Print. When printing of the first color is finished, the pressure contact of the thermal head unit 45 is released, the capstan roller 65 and the pinch roller 66 are rotated in the opposite direction to the printing operation, and the recording paper 13 is returned to the printing start position. The second and subsequent colors are printed by the same operation. In this way, full-color printing is performed by superimposing three colors of yellow, magenta, and cyan.

  When printing is completed, the recording paper 13 is discharged outside the right side of the printer main body 40. If the user performs a printing operation, the above operation is repeated, and printing can be performed until the recording paper 13 and the ink sheet 12 stored in the cartridge 1 run out. Since the recording paper 13 and the ink sheet 12 contain the same number of prints, one of them does not disappear first. In the printer of this embodiment, the absence of the recording paper 13 is detected and the printing operation is not performed.

  Next, a method for detecting the presence or absence of the recording paper 13 will be described with reference to FIGS. FIG. 28B shows a state where the recording paper 13 is still sufficiently in the cartridge 1. As shown in FIG. 28B, the photo reflector 53 is installed in a direction substantially opposite to the recording paper 13. When the printing operation is performed, the pressure plate 60 is pressed against the recording paper 13 so that the recording paper 13 is pressed toward the photo reflector 53 side. The infrared light projected from the photo reflector 53 detects the reflected light on the back surface 13 a of the recording paper 13. Since the recording paper 13 is generally white, it has a relatively high reflectance and is easy to detect. Further, since the detection operation is performed only when the pressure plate 60 is in the pressed position, highly reliable detection can be performed.

  In FIG. 28A, the printing operation is performed in a state where there is no recording sheet 13 in the cartridge 1 and only the protective sheet 14 remains, and the presence or absence of the recording sheet 13 is detected because the pressure plate 60 is in the pressing position. Indicates the state. As shown in FIG. 29, the portion of the protective sheet 14 that faces the photo reflector 53 is provided with ink that reduces the reflectance of infrared light, for example, a black printing portion 14a. The photo reflector 53 reflects the ink. It is determined that there is no recording paper 13 because light cannot be detected. In this embodiment, the low reflectance printing is used. However, the reflected light cannot be detected in the same manner even if a hole having the same size as the printing range is formed instead of printing, so that the same purpose can be achieved. I can do it.

  Next, traveling of the ink sheet 12 during printing will be described. FIG. 30 is a view of the travel path of the ink sheet 12 during printing as viewed from the side opposite to the cartridge insertion opening of the printer main body 40. The ink sheet 12 wound around the first bobbin 12 a is first turned toward the thermal head 47 by the first guide 70 of the upper case 10, printed by the thermal head 47, and then peeled off from the recording paper 13 by the release plate 71. . Thereafter, the ink sheet 12 is further turned by the second guide 72 and the third guide 73 of the lower case 11 and wound around the second bobbin 12b. Since it is necessary to apply a predetermined tension to the ink sheet 12 during printing, a predetermined torque is applied to the first bobbin 12a by a friction spring or the like. Tension is also applied when the recording paper 13 is peeled off by the peeling plate 71. Therefore, a load is applied to the upper case 10 in the direction of the arrow d and the lower case 11 is applied in the direction of the arrow e. The respective loads are torsional loads applied to the upper case 10 and the lower case 11 as moments about the first bobbin 12a and the second bobbin 12b. As described above, the upper case 10 and the lower case 11 are plastic injection-molded products. Further, the upper case 10 includes a feeding port 30 for feeding the recording paper 13, a paper feed roller 48, and a photo reflector 53. For opening 34. For this reason, especially the circumference | surroundings of the supply side accommodating part 20 have low rigidity, and are easy to raise | generate a deformation | transformation. The second guide 72 and the third guide 73 of the lower case 11 are also subjected to a large load due to the tension and the torque at the time of winding in the vicinity of the winding side storage portion 21. A detailed view of part A of FIG. 30 is shown in FIG. As shown in this figure, the loads indicated by arrows g and f are applied to the second guide 72 and the third guide 73, and the vicinity of the second guide 72 and the third guide 73 extends from the vicinity of the bent portion 74 of the lower case 11 in the direction of the arrow h. Acts like a bend.

  When the upper case 10 and the lower case 11 are deformed, the travel path of the ink sheet 12 is distorted, and stable travel is not possible. If stable running is not possible, meandering or wrinkles will occur when winding with the second bobbin 12b. It develops into an important problem for printers where wrinkles appear on the print screen when wrinkles spread on the print path. Therefore, it is very important to stabilize the travel path of the ink ribbon 12.

  In the cartridge 1 of the present embodiment, as described above, the first positioning hole 35 is provided in the end surface of the ink sheet supply side storage unit 20, and the second positioning hole 36 is provided in the vicinity of the end surface of the winding side storage unit 21. (FIG. 1). When the cartridge 1 is loaded in the printer main body 40, the cartridge 1 is fitted to the first positioning shaft 56 and the second positioning shaft 57 (FIGS. 12 to 14), respectively, so that the ink sheet 12 travels without being deformed by the torsional load. It is possible to stabilize the route. Further, the shaft 80 provided in the upper case 10 and the hole 81 (FIG. 4) provided in the lower case 11 were joined by heat welding. As a result, the vicinity of the second guide 72 and the third guide 73 of the lower case 11 increases the sense of unity with the upper case 10, so that the rigidity can be further increased and the travel route can be further stabilized.
