The sliding surface 23A extends in a planar shape so as to go in the fourth direction as it goes in the first direction. The sliding surface 23A is slidable with respect to the sliding surface 122A.

  A schematic configuration inside the housing 30 will be described with reference to FIG. In FIG. 10, illustration of the first housing surface 31 of the housing 30 is omitted. A head holder 76 is fixed inside the housing 30. The head holder 76 is a substantially rectangular plate-like member having a thickness in the vertical direction. A thermal head 73 is provided on the end surface of the head holder 76 in the fifth direction. The thermal head 73 is accommodated in the housing 30 and is exposed in the first direction through the first hole 29 (see FIG. 3). In the lateral direction, the thermal head 73 is disposed on the fourth direction side with respect to the first engagement portion 91 and the second engagement portion 92 and on the third direction side with respect to the first hinge portion 150 and the second hinge portion 250. Is done. The thermal head 73 faces the print medium (not shown) passing through the opening 60A of the tape cassette 60 from the sixth direction.

  A roller holder 74 is provided on the fifth direction side of the tape cassette 60. The roller holder 74 includes a holding portion 74A. The holding portion 74A has a substantially box shape that opens toward the tape cassette 60 side. An end of the holding portion 74 </ b> A opposite to the tape cassette 60 is a contact portion 75. The contact portion 75 is a wall portion that extends in the fifth direction as it goes in the second direction. The contact portion 75 extends in a direction inclined with respect to the first closing direction of the first cover 100. The contact portion 75 can contact the contact surface 105 </ b> A (see FIG. 3) of the first protruding wall portion 105 of the first cover 100. The holding portion 74 </ b> A holds the platen roller 81 on the fourth direction side from the contact portion 75. The platen roller 81 is a roller along the depth direction, and is rotatable about a first axis S extending in the depth direction. The platen roller 81 is connected to a drive motor (not shown) provided in the housing 30. As the driving motor is driven, the platen roller 81 rotates about the first axis S.

  The roller holder 74 can swing between a clamping position (not shown) and a separation position (see FIG. 10) around a second axis W extending in the depth direction on the fourth direction side of the platen roller 81. is there. When the roller holder 74 is in the clamping position, the platen roller 81 clamps the print medium in the opening 60 </ b> A with the thermal head 73. When the roller holder 74 is in the separation position, the platen roller 81 is separated from the thermal head 73 in the fifth direction with the printing medium in the opening 60A in between (see FIG. 10). Further, when the roller holder 74 is at the separation position, the contact portion 75 is on the second direction side of the rectangular hole 33.

  Hereinafter, the clockwise direction around the second axis W when viewed from the first direction is referred to as a first swing direction, and the direction opposite to the first swing direction is referred to as a second swing direction. The first swing direction is the direction in which the arrow M1 faces, and the second swing direction is the direction in which the arrow M2 faces. The clamping position is closer to the first swing direction than the separation position.

  When the roller holder 74 is in the clamping position, the platen roller 81 contacts the thermal head 73 with the print medium in between. Thereby, the roller holder 74 is restricted from swinging in the first swing direction from the clamping position. When the drive motor (not shown) is driven in this state, the platen roller 81 can transport the print medium sandwiched between the thermal head 73 toward the discharge opening 16 (see FIG. 1).

  When the roller holder 74 is in the separated position, the holding portion 74 </ b> A comes into contact with a contact member (not shown) provided inside the housing 30. As a result, the roller holder 74 is restricted from swinging in the second swing direction from the separation position. The roller holder 74 is urged toward the second swinging direction by a holder spring (not shown).

  The roller holder 74 includes a stopper 74B. The stopper 74B is a plate-like wall portion having a thickness in the depth direction, and extends from the holding portion 74A to the fifth direction side (that is, the side opposite to the thermal head 73). The stopper 74B can come into contact with a contact portion 70B of a cutter lever 70 described later.

  A cradle 180 is provided on the third direction side of the tape cassette 60. The cradle 180 faces the print medium conveyed by the platen roller 81 from the sixth direction side. A cutter holder 185 is provided on the fifth direction side of the cradle 180. The cutter holder 185 is a box-shaped body that exposes a cutter (not shown) to be accommodated in the sixth direction. The cutter holder 185 is movable along the vertical direction between a cutting position (not shown) and a cutting standby position (see FIG. 10). When the cutter holder 185 is at the cutting position, the cutter sandwiches the print medium with the cradle 180 and cuts it. When the cutter holder 185 is in the cutting standby position, the cutter is separated from the cradle 180 in the fifth direction with the print medium therebetween.

  A cutter lever 70 is provided on the fifth direction side of the cutter holder 185. The cutter lever 70 has a plate shape having a thickness in the depth direction. The cutter lever 70 is rotatable around a support shaft 79 extending in the depth direction on the third direction side of the cradle 180. The cutter lever 70 is accommodated in the opening 71. More specifically, the cutter lever 70 is located inside the housing 30 from the end surface of the housing 30 in the radial direction with respect to the center line 10A (see FIG. 1).

  The cutter lever 70 includes contact portions 70A and 70B. The contact portion 70A faces the cutter holder 185 from the fifth direction side. For example, when the user rotates the cutter lever 70 with the index finger in the first rotation direction, the contact portion 70 </ b> A comes into contact with the cutter holder 185. The first rotation direction is a counterclockwise direction around the support shaft 79 when viewed from the first direction. The contact portion 70A that contacts the cradle 180 can move the cutter holder 185 from the cutting standby position to the cutting position.

  The contact portion 70B is disposed on the fifth direction side of the stopper 74B. As the cutter holder 185 rotates in the first rotation direction, the contact portion 70B can contact the stopper 74B of the roller holder 74 at the separation position. In this case, the roller holder 74 at the separation position restricts the rotation of the cutter lever 70 in the first rotation direction and restricts the contact between the contact portion 70 </ b> A and the cutter holder 185. As a result, the movement of the cutter holder 185 toward the cutting position is restricted. On the other hand, when the cutter lever 70 is in the clamping position, the stopper 74B does not contact the contact portion 70B. In this case, rotation of the cutter lever 70 in the first rotation direction is allowed, and contact between the contact portion 70A and the cutter holder 185 is allowed. Thereby, the movement of the cutter holder 185 toward the cutting position is allowed.

  A method for exchanging the tape cassette 60 mounted on the housing 30 with another tape cassette 60 will be described with reference to FIGS. 7, 10, and 11. The first cover 100 is engaged with the housing 30 at the first covering position, and the second cover 200 is engaged with the housing 30 at the second covering position. Further, the abutting portion 75 of the roller holder 74 in the clamping position is in contact with the contact surface 105A (see FIG. 3) of the first cover 100.

  For example, the user holds the main body case 10 of the printing apparatus 1 with both hands so that the third direction coincides with the upward direction (see FIG. 11). The user presses the first mark 108 in the fourth direction with, for example, a thumb. 140 A of 1st extending walls of the 1st cover 100 bend in a 4th direction, and the 1st protrusion part 121 bends in a 4th direction (arrow H1 direction of FIG. 7). The first protrusion 122 is displaced from a position (see FIG. 7) in contact with the contact portion 13 of the first housing engaging portion 12 to a position on the fourth direction side with respect to the contact portion 13. That is, the first protrusion 122 moves from a position where it engages with the first housing engaging portion 12 to a position where the engagement with the first housing engaging portion 12 is released. The first cover 100 can be rotated in the first opening direction.

  The user rotates the first cover 100 from the first covering position to the first opening position. As the first cover 100 rotates, the contact surface 105A (see FIG. 3) rotates in the first opening direction. The roller holder 74 swings from the clamping position to the separation position by a biasing force of a holder spring (not shown). The user displaces the first cover 100 rotated to the first opening position in the third direction (the direction of the arrow N1 in FIG. 7). The first protrusion 152 is displaced in the third direction with respect to the contact portion 35B of the first opening 35. As a result, the first cover 100 can be detached from the housing 30. The user removes the first cover 100 from the housing 30 by displacing the first cover 100 in the first direction. The tape cassette 60 is exposed in the first direction. The user replaces the tape cassette 60 attached to the main body case 10 with another tape cassette 60.

  After the tape cassette 60 is replaced, the user causes the two first protrusions 152 of the first cover 100 to enter the two first entry holes 35A of the housing 30 (not shown). The user rotates the first cover 100 in the first closing direction after bringing the first protrusions 152 into contact with the contact portions 35B from the second direction (see FIG. 7). As the first cover 100 rotates, the contact surface 105 </ b> A (see FIG. 3) passes through the rectangular hole 33 and contacts the contact portion 75 of the roller holder 74. The contact surface 105A swings the roller holder 74 from the separation position to the clamping position against the biasing force of the holder spring.

  Further, as the first cover 100 rotates in the first closing direction, the sliding surface 122A of the first protrusion 122 slides with respect to the sliding surface 13A of the first housing engaging portion 12 ( (Not shown). As the first protrusion 121 rotates in the first closing direction while bending in the fourth direction (arrow H1 direction), the first protrusion 122 rotates in the second direction side with respect to the contact portion 13. The bent first projecting portion 121 is displaced in the third direction and returns to the original posture. The first engagement portion 91 engages the housing 30 with the first cover 100 at the first covering position.

  A method of replacing a plurality of batteries 8 (see FIG. 4) with another plurality of batteries 8 (not shown) will be described with reference to FIG. 4, FIG. 9, and FIG. The first cover 100 is engaged with the housing 30 at the first covering position, and the second cover 200 is engaged with the housing 30 at the second covering position.

  For example, the user holds the main body case 10 of the printing apparatus 1 with both hands so that the third direction coincides with the upward direction (see FIG. 11). The user presses the second mark 208 in the fourth direction with, for example, a thumb. 240 A of 2nd extending wall parts of the 2nd cover 200 bend in a 4th direction, and the 2nd protrusion part 221 bends in a 4th direction (arrow H2 direction of FIG. 9). The second protrusion 222 is displaced from a position (see FIG. 9) in contact with the contact portion 23 of the second housing engaging portion 22 to a position on the fourth direction side from the contact portion 23. That is, the second protrusion 222 moves from a position where it is engaged with the second housing engaging portion 22 to a position where the engagement with the second housing engaging portion 22 is released. The second cover 200 can rotate in the second opening direction.

  The user rotates the second cover 200 from the second covering position to the second opening position. When the user displaces the second cover 200 in the second open position in the third direction (the direction of the arrow N2 in FIG. 9), the second protrusion 252 is more than the contact portion 25B of the second opening 25. Displacement in the third direction. As a result, the second cover 200 can be detached from the housing 30. The user removes the second cover 200 from the housing 30 by displacing the second cover 200 in the second direction. The user replaces the plurality of batteries 8 with another plurality of batteries 8.

  After the battery 8 is replaced, the user causes the two second protrusions 252 of the second cover 200 to enter the two second entry holes 25A of the housing 30 (not shown). The user rotates the second cover 200 in the second closing direction after bringing the second protrusions 252 into contact with the contact portions 25B from the first direction (see FIG. 9).

  As the second cover 200 rotates in the second closing direction, the sliding surface 222A of the second protrusion 222 slides with respect to the sliding surface 23A of the second housing engaging portion 22 (not shown). ). The second protrusion 222 rotates in the second closing direction while being bent in the fourth direction (the direction of the arrow H2), whereby the second protrusion 222 rotates toward the first direction with respect to the contact portion 25B. The bent second protrusion 221 is displaced in the third direction and returns to the original posture. The second engaging portion 92 engages the housing 30 with the second cover 200 at the second covering position.

  A case where the user holds the main body case 10 with the first cover 100 and the second cover 200 removed will be described with reference to FIGS. In this case, the roller holder 74 is at a separation position, and the stopper 74B of the roller holder 74 faces the contact portion 70B from the sixth direction side. When the user drops the main body case 10 by mistake, the main body case 10 collides with the ground, for example. Even in this case, since the cutter lever 70 is accommodated in the opening 71, it is difficult to collide with the ground. That is, the printing apparatus 1 can prevent the cutter lever 70 from colliding with the stopper 74B when the cutter lever 70 collides with the ground. Therefore, the printing apparatus 1 can suppress the breakage of the cutter lever 70 and the stopper 74B.

  As described above, the first cover 100 at the first covering position is engaged with the housing 30 by the first engaging portion 91, and the second cover 200 at the second covering position is engaged with the second engagement. The portion 92 is engaged with the housing 30. The user can release the engagement between the first cover 100 and the housing 30 by urging the first mark 108 with the thumb in the fourth direction, for example. The first cover 100 disengaged from the housing 30 can rotate from the first covering position to the first open position. Further, the user can release the engagement between the second cover 200 and the housing 30 by urging the second mark 208 in the fourth direction with, for example, a thumb. The second cover 200 released from the engagement with the housing 30 can rotate from the second covering position to the second opening position. The second engagement portion 92 is provided at a position different from the first engagement portion 91 in the vertical direction. Thereby, when a user cancels | releases engagement with the 1st cover 100 and the housing | casing 30, engagement with the 2nd cover 200 and the housing | casing 30 is hard to be cancelled | released. The operability for the user to release the engagement between the first cover 100 and the housing 30 is improved. Therefore, the printing apparatus 1 includes the first cover 100 and the second cover 200 that are engaged with the housing 30 at a predetermined rotational position, and the operability for releasing the engagement between the first cover 100 and the housing 30 is improved. it can.

  Only by the user urging the first mark 108 in the fourth direction, the engagement between the first cover 100 and the housing 30 is released, and the user urges the second mark 208 in the fourth direction. Only the engagement between the second cover 200 and the housing 30 is released. Therefore, the printing apparatus 1 improves the operability for releasing the engagement between the first cover 100 and the housing 30 and the operability for releasing the engagement between the second cover 200 and the housing 30. it can.

  The first engaging claw 120 is provided in the first part 140C, and the second engaging claw 220 is provided in a part of the second extending wall portion 240A that is shifted from the second part 240D in the sixth direction. When the user holds the main body case 10 with both hands, the user can easily touch the first part 140C and the second part 240D. Therefore, the engagement between the first cover 100 and the housing 30 is easily released compared to the case where the engagement between the second cover 200 and the housing 30 is released. Therefore, the printing apparatus 1 can improve the operability for releasing the engagement between the first cover 100 and the housing 30. In this example, the frequency of replacing the tape cassette 60 is higher than the frequency of replacing the battery 8. Therefore, the printing apparatus 1 can improve the operability of the maintenance work of the printing apparatus 1 by making it easier to release the engagement between the first cover 100 and the housing 30.

  The first mark 108 is provided on the first extending surface 140B, and the second mark 208 is provided on the second extending surface 242. In this example, when the first cover 100 and the second cover 200 are at the first covering position and the second covering position, respectively, the user cannot visually recognize the first engaging claw 120 and the second engaging claw 220. Even in this case, the first mark 108 and the second mark 208 allow the user to visually recognize the arrangement positions of the first engagement claw 120 and the second engagement claw 220, respectively. Therefore, the printing apparatus 1 has the operability for releasing the engagement between the first cover 100 and the housing 30 and the operability for releasing the engagement between the second cover 200 and the housing 30. It can be improved.

  The first mark 108 is a convex portion protruding in the third direction from the first extending surface 140B, and the second mark 208 is a convex portion protruding in the third direction from the second extending surface 242. A user holding the main body case 10 can hook a finger on each of the first mark 108 and the second mark 208. Therefore, the printing apparatus 1 has the operability for releasing the engagement between the first cover 100 and the housing 30 and the operability for releasing the engagement between the second cover 200 and the housing 30. It can be improved.

  Since the operation button 15 exposed by the first hole portion 17A is on the fourth direction side with respect to each of the first hinge portion 150 and the second hinge portion 250, the first engagement of the first engagement portion 91 is performed. The claw 120 is separated from the second engagement claw 220 of the second engagement portion 92. Therefore, when the first cover 100 and the second cover 200 rotate, both the first engagement claw 120 and the second engagement claw 220 are unlikely to contact the operation button 15. Therefore, the printing apparatus 1 can suppress malfunction.

  When the second cover 200 is in the second covering position, the second protruding wall portion 205 faces the plurality of batteries 8 from the second direction. Thereby, the second protruding wall portion 205 suppresses the battery 8 from being displaced from the second hole 37 in the second direction. The printing apparatus 1 can suppress removal of the battery 8 attached to the housing 30.

  The first hinge part 150 and the second hinge part 250 are provided at different positions in the vertical direction. When the first cover 100 and the second cover 200 are detached from the housing 30, the two first protrusions 152 of the first cover 100 cannot enter the two second entry holes 25 </ b> A of the housing 30, respectively. . Similarly, the two second protrusions 252 of the second cover 200 cannot enter the first entry hole 35 </ b> A of the housing 30, respectively. Therefore, the printing apparatus 1 can suppress the first cover 100 and the second cover 200 from being attached to the housing 30 at incorrect positions.

  The user can swing the roller holder 74 from the separation position to the clamping position only by rotating the first cover 100 from the first opening position to the first covering position. Therefore, the printing apparatus 1 can improve the operability of swinging the roller holder 74 from the separation position to the clamping position.
