Further, the special thickness cartridge 4b on which the 36 mm width printing tape is mounted is mounted so as to escape the raised block 37 by a depression (step) 41 formed on the lower surface thereof and to come into contact with the bottom plate 31 (FIG. 6). reference).
[0031]
Further, the tape cartridge (cartridge case) 4 is formed with a pair of recesses 42 and 42 that engage with holding claws 61 and 61 of a clamping and urging mechanism 23 described later (see FIG. 8). The lower side of each recess 42 is formed as an outwardly inclined surface 42a, and each holding claw 61 contacts this portion. Each holding claw 61 presses the inclined surface 42 a of the recess 42, so that the component force presses the tape cartridge 4 against the bottom surface (the upper surface of the bottom plate 31 or the upper surface of the raised block 37) 38 of the cartridge mounting portion 7. Works. A pair of tongue-shaped gripping projections 43 and 43 are formed on both side surfaces of the tape cartridge 4 adjacent to the respective recesses 42, and serve as a finger hook when the tape cartridge 4 is attached and detached (FIG. 6). reference).
[0032]
On the other hand, inside the opening / closing lid 6, a pair of pressing mechanisms (pressing biasing means) 24 for pressing and biasing the mounted tape cartridge 4 from the mounting direction (vertical direction) toward the bottom surface 38 of the cartridge mounting portion 7, 24 is provided integrally. A head operation piece 39 that operates a print head moving mechanism (not shown) and an operation piece 40 that acts on the right clamping and urging mechanism 23a, which will be described in detail later, are integrally formed inside the right portion of the opening / closing lid 6. Is provided.
[0033]
As shown in FIG. 5, each pressing mechanism 24 receives a pressing claw 51 that directly contacts and presses the tape cartridge 4, a coil spring 52 that urges the pressing claw 51 in the vertical direction, and a coil spring 52. The spring receiving piece 53 includes a coil spring 52 and a pressing claw holder 54 that slidably holds the pressing claw 51. The pressing claw holder 54 has a plurality of ribs 55 at the base, and is integrally protruded inside the opening / closing lid 6. Stopper slits 56 are formed on both sides of the pressing claw holder 54 to guide the slide of the pressing claw 51 and restrict the protruding end position.
[0034]
The spring receiving piece 53 is provided inside the pressing claw holder 54 so as to protrude integrally with the opening / closing lid 6, and receives the coil spring 52 in a positioned state by a convex portion (not shown) formed at the tip. One end of the coil spring 52 is in contact with the spring receiving piece 53 and the other end is in contact with a receiving hole (not shown) formed on the proximal end side of the pressing claw 51. The pressing claw 51 has a distal end formed in a wedge shape, and is slidably held on the inner surface of the pressing claw holder 54 at the proximal half. Further, a pair of stopper projections 57 project from the outer surface of the pressing claw 51 on the proximal end side, and the stopper projections 57 are slidably engaged with the stopper slits 56 of the pressing claw holder 54. .
[0035]
As shown in FIGS. 3 and 4, the pair of pressing mechanisms 24, 24 configured in this way are arranged in a state where the left and right are reversed, and have exactly the same structure. When the opening / closing lid 6 is closed, the left pressing mechanism 24 comes into contact with and presses the gripping protrusion 43 formed on the tape cartridge 4 (see FIG. 6). The corner of the tape cartridge 4 that is directly above the detection switch 35 is pressed and urged.
[0036]
As shown in FIG. 6, when the standard cartridge 4a having a small thickness is pressed and biased, the coil spring 52 of each pressing mechanism (only the left pressing mechanism 24 is shown in the figure) 24 is relatively weakly contracted. When the thick special thickness cartridge 4b is pressed and biased, the coil spring 52 of each pressing mechanism 24 is biased in a relatively strongly contracted state.
[0037]
As shown in FIGS. 7 and 8, of the pair of sandwiching and biasing mechanisms 23 a and 23 b that are opposed to each other, the right sandwiching and biasing mechanism 23 a includes a holding claw 61 that directly engages with the recess 42 of the tape cartridge 4, and The auxiliary urging member 62 that slides toward the holding claw 61 by the operating piece 40 formed on the opening / closing lid 6, the coil spring 63 interposed between the holding claw 61 and the sub urging member 62, and the holding claw A claw receiving block 64 that rotatably supports 61 and a cover 65 that covers the auxiliary biasing member 62 and the coil spring 63 are configured.
[0038]
The holding claw 61 includes a rotation base 67 having a substantially circular cross section seated on a semicircular receiving portion 64 a of the claw receiving block 64 and an L-shaped arm portion 68 extending from the rotation base 67 in an “L” shape. And the claw portion 69 formed at the tip of the L-shaped arm portion 68 are integrally formed. The claw portion 69 is formed with an inclined surface 69 a that applies a downward component force to the inclined surface 42 a of the concave portion 42 of the tape cartridge 4. That is, the inclined surface 69a of the claw portion 69 is formed in a complementary shape with the inclined surface 42a of the concave portion 42, and the inclined surface 69a of the claw portion 69 presses the inclined surface 42a of the concave portion 42 in the lateral direction. The tape cartridge 4 is pressed downward (longitudinal direction).
[0039]
The auxiliary biasing member 62 is attached to the rectangular guide hole 70 formed by a part of the mounting portion case 3 and surrounded by the claw receiving block 64 and the cover 65 so as to be able to advance and retreat. An upward inclined cam surface 71 with which the operating piece 40 of the opening / closing lid 6 is engaged (contacted) is formed. When the opening / closing lid 6 is closed, the auxiliary biasing member 62 advances toward the holding claw 61 by a cam action between the lower end of the operating piece 40 and the inclined cam surface 71.
[0040]
The coil spring 63 is disposed between the front end portion of the auxiliary biasing member 62 and the back surface of the holding claw 61. When the auxiliary biasing member 62 advances, the coil spring 63 contracts and the holding claw 61 is taped. Strongly biased toward the cartridge 4 side. On the other hand, when the opening / closing lid 6 is opened, the operating piece 40 is separated from the sub urging member 62, and the sub urging member 62 is retracted by the coil spring 63 to weaken the spring force of the coil spring 63. That is, when the opening / closing lid 6 is closed, the tape cartridge 4 is strongly clamped and biased, and when the opening / closing lid 6 is opened, the tape cartridge 4 is weakly clamped and biased. Although not shown, a stopper that restricts the retracted position of the sub urging member 62 is disposed behind the sub urging member 62.
[0041]
Similarly, the left urging / biasing mechanism 23b includes a holding claw 61 that directly engages with the recess 42 of the tape cartridge 4, a coil spring 63 that urges the holding claw 61 in the clamping direction (lateral direction), and a holding claw 61. Is configured by a claw receiving block 64 that supports the coil spring 63 and a cover 65 that covers the coil spring 63. The coil spring 63 is interposed between the side wall portion of the cover 65 and the holding claw 61 and receives the cover 65 to urge the holding claw 61 in the lateral direction.
[0042]
Also in this case, the holding claw 61 includes a rotation base 67 that is rotatably seated on the receiving portion 64 a of the claw receiving block 64, an L-shaped arm portion 68, and a claw portion 69 formed at the tip of the L-shaped arm portion 68. Thus, they are integrally formed. Further, the claw portion 69 cooperates with the concave portion 42 of the tape cartridge 4 to apply a downward component force and presses the tape cartridge 4 downward (vertical direction).
[0043]
Here, with reference to FIG. 6, FIG. 8, and FIG. 9, the holding mode of the tape cartridge 4 mounted on the cartridge mounting portion 7 will be described separately for the standard cartridge 4a and the special thickness cartridge 4b. As described above, the standard cartridge 4a and the special thickness cartridge 4b are different in thickness, the standard cartridge 4a is seated on the raising block 37, and the special thickness cartridge 4b is seated on the bottom plate 31. Further, in the mounted state, the gripping protrusion 43 and the concave portion 42 of the special thickness cartridge 4b come to a position (level from the bottom surface 38) higher than the gripping protrusion 43 and the concave portion 42 of the standard cartridge 4a. For this reason, the left and right holding claws 61, 61 are appropriately engaged with the recess 42 in the standard cartridge 4a, but simply contact the lower side of the recess 42 in the special thickness cartridge 4b.
[0044]
In the cartridge mounting portion 7, both holding claws 61, 61 of the left and right holding and biasing mechanisms 23 a, 23 b facing each other face, and the tape cartridge 4 resists both the holding claws 61, 61 against each coil spring 63. And then push it open. In this mounted state, the tape cartridge 4 is clamped and urged with a relatively weak force by the coil spring 63 and is pressed against the bottom surface 38 of the cartridge mounting portion 7 with a relatively weak force. Subsequently, when the opening / closing lid 6 is closed, the pair of pressing mechanisms 24, 24 provided on the opening / closing lid 6 strongly presses the tape cartridge 4 against the bottom surface 38 of the cartridge mounting portion 7. At the same time, the operating piece 40 of the opening / closing lid 6 presses the holding claw 61 of the right holding / biasing mechanism 23 a via the coil spring 63. As a result, the tape cartridge 4 is strongly pressed against the bottom surface 38 of the cartridge mounting portion 7 and is strongly clamped (see FIGS. 6A and 8).
[0045]
On the other hand, in the special thickness cartridge 4b as described above, the holding claws 61 of the left and right clamping and urging mechanisms 23a and 23b do not engage with the concave portions 42 of the tape cartridge 4, so that the holding claws 61 are pressed against the bottom surface 38. Force does not work. However, the thick tape cartridge 4 is strongly pressed against the bottom surface 38 by the pair of pressing mechanisms 24, 24 (see FIGS. 6B and 9). In addition, since both holding claws 61, 61 are pushed open, the tape cartridge 4 is clamped with a relatively strong force. Therefore, both the standard cartridge 4a and the special thickness cartridge 4b receive substantially the same spring force, and are strongly pressed against and firmly held by the bottom surface 38 of the cartridge mounting portion 7.
[0046]
As described above, the tape cartridge 4 is held stationary by the lateral clamping force and the vertical pressing force in the closed cartridge mounting portion 7. Therefore, rattling and floating of the tape cartridge 4 can be effectively prevented, and the printing quality and stability in detecting the tape cartridge 4 can be improved. Further, when the opening / closing lid 6 is opened, the spring force of the pressing mechanism 24 is released and the pressing state of the holding claw 61 by the operating piece 40 is released, so that the tape cartridge 4 can be easily attached and detached with a weak force. be able to.
[0047]
Further, the tape cartridge 4 is uniformly pressed by the pair of pressing mechanisms 24, 24, and the vicinity of the print head 32 and the portion facing the detection switch 35 are pressed, so that printing defects and detection errors are effectively prevented. . Moreover, since the pressing mechanism 24 and the clamping and biasing mechanisms 23a and 23b bias the tape cartridge 4 using the coil springs 52 and 63, unlike the biasing member such as a resin having spring property, That sag can be reliably prevented.
[0048]
The pressing mechanism is not limited to two in the embodiment, and may be three or more. Also, the types of tape cartridges are not limited to four. Further, the sandwiching and urging mechanism does not necessarily have a structure in which a vertical component force is applied.
[0049]
【The invention's effect】
As described above, according to the tape cartridge holding mechanism of the present invention, the clamping cartridge is strongly clamped when the opening / closing lid is closed by the clamping biasing means provided in the cartridge mounting portion and the pressing biasing means provided in the opening / closing lid. At the same time, the tape cartridge can be strongly pressed against the bottom surface of the cartridge mounting portion, and when opened, the tape cartridge can be easily attached to and detached from the cartridge mounting portion with a weak force. Therefore, the tape cartridge can be securely and immovably held in the cartridge mounting portion without impairing the ease of attachment and detachment, and defective printing can be effectively prevented.
[0050]
Further, according to the tape printer of the present invention, the tape cartridge can be held immovably in the cartridge mounting portion, so that it is possible to effectively prevent a detection error of the tape cartridge, skewing of the tape, and jamming, and The tape cartridge can be attached and detached with a weak force. Therefore, the usability and reliability of the device can be improved.
