  First, a schematic configuration of the cassette 1 will be described with reference to FIGS. As shown in FIG. 1, the cassette 1 has an upper case 2 and a lower case 3. The cassette 1 has characters on the film tape 17 by a support hole 4 for rotatably supporting a tape spool 18 wound with a film tape 17 as a tape-shaped print medium to be described later, and a thermal head 44 to be described later. When the ink ribbon 19 is drawn out from the ribbon spool 20 and the ribbon take-up spool 21 is wound up, the release hole of the double-sided adhesive tape 22 to be described later is wound outward. A support hole 6 for rotatably supporting the tape spool 23 is formed. The lower case 3 is similarly formed with support holes 4, 5, 6 facing the support holes 4, 5, 6 of the upper case 2.

  Further, the front side of the cassette 1 (referring to the side where the arm portion 8 is present, hereinafter the same) guides the film tape 17 drawn from the tape spool 18 and the ink ribbon 19 drawn from the ribbon spool 20, An arm portion 8 (details of which will be described later) constituting a guide portion that feeds out from the opening 8A is provided, and a thermal head 44 (to be described later) of the tape printer is placed behind the arm portion 8 in a cassette. A head mounting portion 9 is provided to be fitted when one set is made. Furthermore, a first fitting portion 10 that enters the rear of the cassette 1 is formed in the wall portion 9A facing the arm portion 8 in the head mounting portion 9, and the first side wall of the head mounting portion 9 has a first fitting portion 10 on the left side wall. The 2nd fitting part 11 which entered the direction (direction along wall part 9A) orthogonal to the fitting part 10 is formed. As will be described later, each of the first fitting portion 10 and the second fitting portion 11 is fitted to two protrusions (not shown) formed on the head holder 45 that supports the thermal head 44. Thus, the head holder 45 is securely attached to the head attachment portion 9 without interfering with the ink ribbons 19 and the film tape 17.

  Further, with respect to the traveling direction of each ink ribbon 19 and film tape 17, on the downstream side of the head mounting portion 9, a tape feed roller 12 is rotatably supported by a support hole, and the tape feed roller 12 is opposed thereto. The film tape 17 and the double-sided adhesive tape 22 are pulled out from the tape spool 18 and the tape spool 23 in cooperation with a sub-roller (not shown) that is pressed against the tape feed roller 12 from the side to be moved, and an ink ribbon is drawn by the thermal head 44. The film tape 17 on which characters and the like are printed via 19 and the double-sided adhesive tape 22 are bonded to each other.

  Further, a pair of upper and lower restricting members 14 and 14 are provided in the vicinity of the tape feed roller 12, and each of the restricting members 14 and 14 prints characters or the like on the downstream side of the thermal head 44. The film tape 17 is regulated and guided in the width direction so that the film tape 17 and the double-sided pressure-sensitive adhesive tape 22 can be properly bonded without causing a positional shift.

  A second detected portion (contacted portion) 15 and a first detected portion (contacted portion) 13 are substantially halfway in the thickness direction of the cassette 1 at the left and right side edges on the rear side of the cassette 1. It is provided to project in a bowl shape. In the first detected portion 13 at the right rear edge position of the cassette 1, the type of the cassette 1 is specified by the type of the cassette 1 (for example, the width of each film tape 17, the color of ink applied to the ink ribbon 19, etc.). A plurality of switch holes 13A having a predetermined pattern are formed in the vertical direction. The formation pattern of the switch holes 13A is different depending on the type of each cassette 1, and the pattern formed by each switch hole 13A is disposed in the cassette storage portion 31 on the print tape creating device 25 side. The detection is based on a combination of ON and OFF of a plurality of detection switches 32 (see FIG. 7) protruding from the detection unit 40. Further, the first detected portion 13 is formed with a pin hole (fitting portion) 38 into which a positioning pin (pin) 36 described later is fitted.

  Next, the configuration of the print tape creating device 25 will be described with reference to FIGS. As shown in FIGS. 8 to 10, the rear end of the lid 27 is pivoted up and down about the shaft 28 attached to the rear end of the main body case 26 in the printing tape creating device 25 so that it can be opened and closed. Has been. A key touch panel 29 for inputting print data and a print command is provided on the upper front side of the main body case 26. On the rear side of the main body case 26, an open top cassette storage portion 31 is formed. The cassette housing 31 is provided with a head holder 45, a tape drive shaft 33 with an engagement rib, and a ribbon take-up shaft 34 with an engagement rib from a metal bottom frame 30. Is set in the cassette housing portion 31, the tape drive shaft 33 is fitted into the inner diameter portion of the tape feed roller 12, and the ribbon take-up shaft 34 is fitted into the inner diameter portion of the ribbon take-up spool 21. Then, the tape drive shaft 33 and the ribbon take-up shaft 34 are rotated via a drive motor and a transmission gear group (not shown).

  The cassette housing 31 is configured so that cassettes 1 having different width dimensions of the film tape 17 can be set as appropriate. In this case, if the width dimension of the film tape 17 (corresponding ink ribbon 19) stored in the cassette 1 is different, the cassette thickness dimension H1 from the upper case 2 to the lower case 3 of the cassette 1 is necessarily different. Regardless of the cassette thickness dimension H1, the first detected portion 13, the second detected portion 15, and the hook-shaped protrusion 16 on the right front portion of the cassette 1 (see FIGS. 1 and 2A) Are formed so as to have the same thickness dimension H2. For example, the cassette dimension H1 of the cassette 1 containing the 12 mm film tape 17 shown in FIGS. 8 and 9 is the cassette dimension H1 of the cassette 1 containing the 24 mm film tape 17 shown in FIGS. Although different, the thickness dimension H2 of the first to-be-detected portion 13 and the second to-be-detected portion 15 of the respective cassettes 1 and the hook-shaped projection portion 16 are all the same.

  On the other hand, as shown in FIGS. 4, 5, and 9 to 12, the two positioning pins (pins) 35 and 36 erected upward from the bottom frame 30 are formed in a recessed manner in the cassette 1. The cassette 1 is set in an appropriate position in the cassette housing portion 31 by being fitted into the holes (fitting portions) 37 and 38 and the tip surfaces of the positioning pins 35 and 36 are in contact with the bottom surfaces of the pin holes 37 and 38. It is something that can be done.

  Further, the detection unit 40 in which the detection switch 32 on the right rear side of the cassette storage unit 31 is disposed is opposed to the lower surface of the first detected unit 13 in the cassette 1, and on the other hand, the left rear side of the cassette storage unit 31. The support pin 41 erected in contact with the lower surface of the second detected portion 15 and the support pin 42 erected from the right front side of the cassette housing portion 31 are in contact with the lower surface of the protrusion 16 in the cassette 1. (See FIGS. 9 to 11).

  Therefore, by setting the height dimensions of the positioning pins 35 and 36 and the support pins 41 and 42 as the support portions to predetermined values, each cassette 1 is substantially horizontal regardless of the thickness of the cassette. Is set so that the center height position in the width direction of the film tape 17 to be supported and accommodated is the same.

  Next, a description will be given of the configuration of the cassette storage detection device that can detect whether or not the cassette 1 is set in the cassette storage unit 31 in an appropriate posture. As shown in FIGS. 4 and 8 to 14, the inner surface of the lid 27 for covering the upper portion of the cassette housing 31 so as to be openable and closable is on the left and right sides on the side close to the shaft 28 that is the rotation center A pair of pressing bodies, that is, a first pressing body (pressing part) 51 and a second pressing body (pressing part) 52 project downward. In this case, the pressing bodies 51 and 52 can be integrally formed with the synthetic resin lid body 27. The first pressing body 51 is arranged at a position where the upper surface of the first detected part 13 in the cassette 1 set in the cassette housing part 31 can be pressed downward, and the second pressing body 52 is also the second detected part. It arrange | positions in the position which can press the upper surface of 15 downward. In this reference embodiment, the cross section of the first pressing body 51 and the second pressing body 52 is a flat plate with a reinforcing rib and has a flat pressing portion 55 on the lower end surface.

  Since the first pressing body 51 and the second pressing body 52 are long in the downward direction and provided on the side close to the rotation center of the lid body 27, the lid body 27 is greatly opened. In order not to interfere with the back wall 26a of the main body case 26, the back wall 26a has notches 53 and 54 through which the first pressing body 51 and the second pressing body 52 can pass as the lid body 27 rotates. It is formed (see FIGS. 5 and 6). With this configuration, for example, the cassette 1 in which the film tape 17 having a width of 12 mm is stored is set in the normal position and position in the cassette storage unit 31. The normal position means that the positioning pins 35 and 36 are inserted in parallel into the pin holes 37 and 38 for positioning the cassette 1, and the front end surfaces of the positioning pins 35 and 36 are on the bottom surfaces of the pin holes 37 and 38. The cassette 1 that is set is in a horizontal position (the first detected portion 13, the second detected portion 15, and the protruding portion 16 of the cassette 1 at the tips of the support pins 41 and 42 as supporting portions. The normal posture is that the lower surfaces of the two are in contact with each other.

  Next, in the state where the lid 27 is closed, as shown in FIGS. 8 and 14, the first detected portion 13 is pressed downward by the first pressing body 51, so that the bottom surface of the pin hole 38 and the positioning pin 36 are While the front end surface is firmly and securely abutted, as shown in FIGS. 9 and 14, the second detected body 15 is pressed downward by the second pressing body 52, and the lower surface thereof is supported on the support pin 41. And firmly supported. In such a state, since the set cassette 1 is in a horizontal state and set in a normal position, the detection switch 32 is fitted in the predetermined switch hole 13A in the first detected portion 13, The type of the cassette can be detected, and the lid 27 closes tightly and becomes substantially the same surface as the main body case 26, so that the operator can set the cassette 1 in the normal position and in the normal posture. Can be judged immediately.

  FIGS. 10 and 11 show the case where the cassette 1 storing the film tape 17 having a width of 24 mm is set in the normal position and in the normal position in the cassette storage portion 31. FIG. In this case as well, the lid 27 closes exactly as described above, so that it can be immediately determined that the cassette 1 is set in the proper position and in the proper posture.

  Note that FIG. 12 shows a state in which the portion of the second detected portion 15 is set in an irregular posture in which the portion of the second detected portion 15 is lifted, such as when the cassette 1 is fitted in an inclined shape with respect to the cassette housing portion 31. In this case, the second pressing body 52 cannot press the second detected portion 15 at the normal position (the pressing portion 55 at the lower end of the second pressing body 52 is not connected to the corner of the second detected portion 15 or the like). Therefore, the lid 27 is in a semi-closed state (a state in which there is a large gap with respect to the upper surface of the main body case 26), and the user can immediately determine that the cassette 1 is not set in a normal posture. It is.

  Similarly, when the cassette 1 is set in a state where the first detected portion 13 is lifted, the first pressing body 51 cannot press a predetermined portion of the first detected portion 13 and the lid 27 is semi-closed. It becomes a state. Further, even when both the first detected portion 13 and the second detected portion 15 are lifted, the lid 27 does not close tightly, so that the cassette storing posture can be immediately determined.

  Next, a second embodiment and a reference example of the present invention will be described with reference to FIGS. 15 is a right sectional view of the main body case in a state where the cassette 1 is set in the cassette housing part 131 in the reference example, FIG. 16 is a plan view showing the inner side of the lid 127, and FIG. 17 is a plan view showing the lid 127 shown in FIG. 18 is a side view seen from the direction of the arrow 16A, FIG. 18 is a side view seen from the direction of the arrow 16B of the lid 127 shown in FIG. 16, and FIG. 19 is a state in which the cassette 1 is set in the cassette storage portion 231 in the second embodiment. FIG. 20 is a plan view showing the inside of the lid 227 in the second embodiment, FIG. 21 is a side view of the lid 227 shown in FIG. 20 as viewed from the direction of the arrow 20A, and FIG. FIG. 23 is a perspective view of the printing tape producing device at the lid opening position in a state where the cassette 1 is set in the cassette housing portion 331 in the reference example, and FIG. 24 is a side view of the lid 227 shown in FIG.
