Description

  The present invention relates to a tape printing apparatus having a configuration in which a tape is printed by pressure contact with a thermal head while being pulled out from a tape cassette mounted on a tape cassette mounting portion, and discharged to the outside upon completion of printing. The present invention also relates to a tape printing apparatus capable of properly printing characters and the like on a printing tape while properly maintaining the positional relationship between the platen roller and the thermal head even when using a manufactured head mounting plate.

  Conventionally, the printing tape is transported by a platen mechanism that moves between an operation position where printing is possible and a standby position where printing is impossible in conjunction with the attachment or detachment or opening / closing of the cover that covers the cassette storage section. Various tape printers have been proposed in which a tape is printed by pressure contact with a thermal head and discharged to the outside upon completion of printing.

  For example, Japanese Patent Application Laid-Open No. 8-25753 discloses a printing tape transport unit, a thermal head for printing on the printing tape, and a heat generation of the thermal head, at least in a frame of a cassette storing a printing tape. A tape printer is described that includes a platen that contacts and separates from the element. In such a tape printer, a thermal head is provided on a substrate on which a holder shaft for rotatably supporting a platen holder provided with a platen is provided, and the head support is formed in a plate shape from a metal such as iron. The member is mounted with its position adjusted in advance.

Japanese Patent Laid-Open No. 8-25753 (page 3, page 4, FIG. 2, FIG. 3)

  However, in the configuration in which the head support member provided with the thermal head is adjusted in advance and attached to the above-described substrate on which the holder shaft is erected, the head support member is made of metal such as iron, and this is attached to the substrate. Therefore, there is a problem that the number of work steps increases and the manufacturing cost increases.

In order to solve the above problem, it is conceivable to integrally mold a head mounting plate on which a thermal head is mounted together with a tape cassette mounting portion of a tape printer with a resin.
However, since the head mounting plate molded from resin is inevitably elastically deformed, when the platen roller is pressed against the thermal head when printing characters or the like on the printing tape, the thermal head is removed from the platen roller. The head mounting plate is elastically deformed due to the pressure contact force exerted on the head.
When the head mounting plate is elastically deformed in this way, the positional relationship between the platen and the thermal head is shifted, and as a result, characters and the like cannot be printed properly on the printing tape.
Further, as the number of times of printing of characters and the like increases, the elastic restoring force of the head mounting plate may decrease, and eventually creep deformation may not be restored. In such a case, it is obvious that characters or the like can no longer be printed on the printing tape.

  Accordingly, the present invention has been made to solve the above-described problems. When the platen roller is pressed against the thermal head during printing of characters or the like on the printing tape, the pressure contact exerted from the platen roller to the head mounting plate. By configuring the force to be received by the entire tape printer, it is possible to reliably prevent the head mounting plate from tilting or moving even when using a resin head mounting plate that is easily elastically deformed.

A second rib 41 is formed in a vertical direction with respect to the bottom surface of the tape cassette mounting portion 27. In the present embodiment, two second ribs 41 are illustrated.

When the tape cassette 26 is mounted on the tape cassette mounting portion 27, the outer side surface 26 </ b> A (see FIG. 6) of the tape cassette 26 is brought into contact with each of the second ribs 41. As a result, the tape cassette 26 is positioned by the second ribs 41.
Further, the height of each second rib 41 is formed so as to be higher than the head mounting plate 33 and lower than the guide plate 39. In this respect, when the tape cassette 26 is mounted on the tape cassette mounting portion 27, the guide plate 39 is first inserted into the head insertion portion 36 of the tape cassette 26. Next, the outer surface 26 </ b> A of the tape cassette 26 starts to come into contact with the second ribs 41 during the insertion, and then the head mounting plate 33 is inserted into the head insertion portion 36.

  Subsequently, a configuration in which the platen holder is rotated and fixed to the thermal head 32 side will be described. When the back cover 3 is attached to the back surface portion of the main body 2, a projection (not shown) provided on the inner surface of the back cover 3 enters the engagement hole 34 of the partition member 30, and the side surface portion of the platen holder Since the platen holder is interposed between the position fixing portion 35 and the position fixing portion 35, the platen holder is rotated at the thermal head 32 side and fixed at a position where the platen holder abuts on the inner surface of the projection portion by the biasing force of the torsion spring. Hereinafter, such a position is referred to as an “operation position”). Further, when the platen holder is rotated to the operating position, the platen roller 23 is pressed against the thermal head 32, so that it is formed in a substantially horizontal U shape supported on the outer surface of the lower end in the longitudinal direction of the platen holder. The pressing spring (not shown) moves outward while being bent. As a result, the platen roller 23 presses the printing tape against the thermal head 32 with a pressing force corresponding to the amount of bending of the pressing spring, and printing can be performed on the printing tape.

  Next, the configuration of the tape cassette 26 will be described with reference to FIG. 5. In the tape cassette 26, a printing tape in which a release paper is affixed to an adhesive layer applied to the opposite surface of the character printing surface is wound around a tape spool. It is stored in a rotated state. The printing tape is guided to the arm-shaped guide portion 42 formed in the tape cassette 26 through the rotational force of the platen roller 23 when printing characters and the like, and the tape outlet 8 formed in the guide portion 42. It is pulled out from. The printed tape after printing is taken out of the tape printer 1 through the tape outlet 8.

The head insertion part 36 which penetrates the attachment plate 33 and the said 1st rib 33A is comprised.
Further, an insertion hole 40 is formed in the tape cassette 26 corresponding to the guide plate 39 formed in the tape cassette mounting portion 27, and the tape cassette 26 is connected to the tape cassette mounting portion 27 in the insertion hole 40. When mounting on the guide plate 39, the guide plate 39 is inserted.

  Next, the operation of mounting the tape cassette 26 configured as described above on the tape cassette mounting portion 27 will be described with reference to FIGS. 5, 6, 7 and 8. FIG. 8 is an explanatory view showing a state in which the tape cassette 26 is mounted on the tape cassette mounting portion 27.

  In order to mount the tape cassette 26 in the tape cassette mounting portion 27, the tape cassette 26 is kept close to the tape cassette mounting portion 27 while maintaining the substantially horizontal state. First, the insertion hole 40 of the tape cassette 26 is formed. Then, the guide plate 39 is inserted into the highest guide plate 39 while being positioned. When the insertion hole 40 is slightly inserted through the guide plate 39, the tape cassette 26 is basically positioned with respect to the tape cassette mounting portion 27. When the tape cassette 26 is further moved downward in this state, the outer side surface 26A (the left side surface in FIG. 5) of the tape cassette 26 comes into contact with the second highest ribs 41, whereby the tape The positional relationship of the tape cassette 26 with respect to the cassette mounting portion 27 is determined.

  Accordingly, the tape cassette 26 can be moved further downward while the insertion hole 40 of the tape cassette 26 is inserted into the guide plate 39 and the outer surface 26A of the tape cassette 26 is in contact with each second rib 41. For example, the lowest head mounting plate 33 and the first rib 33 </ b> A are automatically inserted into the head insertion portion 36 of the tape cassette 26.

  As described above, when the tape cassette 26 is mounted on the tape cassette mounting portion 27 according to the above-described procedure, first, the highest guide plate 39 and the insertion hole 40 are determined, and then the second highest second rib 41 and the tape cassette are determined. 26, the positional relationship between the lowest thermal head mounting plate 33 and the head insertion portion 36 can be reliably prevented from shifting, and the first rib 33A can be prevented from shifting. Each second rib 41 enables the tape cassette 26 to be mounted at a fixed position in the tape cassette mounting portion 27.

  Next, the operation of the tape printer 1 will be described with reference to FIG. FIG. 9 is an explanatory diagram of the usage status of the tape printer 1 in this embodiment. As shown in FIG. 9, the operator uses the thumb of the left hand holding the grip 11 of the tape printer 1 while displaying the print data on the liquid crystal display device 6, each character input key 12, the space key 13, and the switch key 14. Then, the desired print data is easily created by pressing the cursor key 16, the return key 18, etc., and when the print key 15 is pressed with the thumb of the left hand, it is printed on the print tape. Thereafter, by pressing the cut lever 7 inward with the thumb of the left hand holding the tape printer 1, the print tape on which the desired print data is printed is cut and discharged from the tape discharge port 8, and the operator prints the tape. A tape on which arbitrary print data is printed can be obtained only by operating the left hand having the grip portion 11 of the apparatus 1.

When printing on the printing tape, the platen holder moves to the operating position inside the tape printer 1, whereby the pressure contact force by the platen roller 23 is applied to the head mounting plate 33 via the printing tape. Become. In the case of the present embodiment, the first rib 33 </ b> A formed integrally with the head mounting plate 33 is in contact with the side surface 36 </ b> A of the head insertion portion 36 in the tape cassette 26 and is provided on the inner peripheral surface of the tape cassette mounting portion 27. The plurality of second ribs 41 are in contact with the outer surface 26 </ b> A of the tape cassette 26. Therefore, the pressing force of the platen roller 23 applied to the head mounting plate 33 is received by the entire tape printer 1 from the first rib 33A, the tape cassette 26, and the second ribs 41.
Accordingly, the resin-made head mounting plate 33 that is easily elastically deformed can be reliably prevented from being inclined or moved, and the arrangement relationship between the thermal head 32 and the platen roller 23 is always in an appropriate position. Can be maintained. As a result, it is possible to provide the user with the tape printer 1 that can maintain high print quality on the print tape over a long period of time.

Since the first rib 33A is formed in a tapered shape that gradually expands toward the bottom surface of the tape cassette mounting portion 27, when the tape cassette 26 is mounted on the tape cassette mounting portion 27, the head insertion in the tape cassette is inserted. The side surface 36A of the portion 36 can be smoothly guided downward along the tapered shape of the first rib 33A. Thus, even when the first rib 33A is formed on the head mounting plate 33, the mounting property of the tape cassette 26 to the tape cassette mounting portion 27 is not impaired.
Further, since the plurality of second ribs 41 are formed on the inner peripheral surface of the tape cassette mounting portion 27, the outer surface 26A of the tape cassette 26 is stably brought into contact with the plurality of second ribs 41. It becomes possible. Accordingly, when the platen roller 23 is pressed against the thermal head 32, the pressure contact force exerted from the platen roller 23 to the head mounting plate 33 is applied to the tape through the first rib 33A and the plurality of second ribs 41 from the tape cassette 26. It can be transmitted to the entire printing apparatus 1.

Note that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the scope of the present invention.
For example, the following may be used.

  In the embodiment, both the first rib 33A and the second rib 41 are provided. However, only the first rib 33A or only the second rib 41 may be provided. Further, in the present embodiment, the head mounting plate 33 is erected vertically with a substantially rectangular horizontal section, and the first rib 33A is formed in a tapered shape. However, the head mounting plate 33 is tapered in the vertical direction. It is good.
