Engage.

  The operation of the ratchet mechanism 34 will be described with reference to FIGS. Here, FIG. 9 is a view showing the ratchet mechanism 34 according to the present embodiment, and is a longitudinal side view showing a state in which the cam member 36 is located at the first position, and FIG. 10 is a ratchet according to the present embodiment. It is a figure which shows the mechanism 34, Comprising: It is a vertical side view which shows the state in which the cam member 36 was located in the 2nd position.

  In the ratchet mechanism 34, when the operation portion 21 is positioned at the “medium” position, the head portion 41b of the engagement piece 41 is connected to the third engagement portion 36f of the cam member 36 as shown in FIG. The cam member 36 is positioned at the third position. This state is the third aspect. In this case, the first and second ratchet claws 36a and 36b are in a state of being separated from the ratchet teeth 33a of the ratchet gear 33 (non-engagement state). In this state, the ratchet gear 33 is rotatable in one direction and the other direction (forward / reverse direction). From this state, when the operation unit 21 is positioned at the “strong” position, as shown in FIG. 9, the cam member 36 is rotated in the other direction (the direction of the arrow B in the figure) to The head 41b engages with the first engaging portion 36d of the cam member 36, and the cam member 36 is positioned at the first position. This state is the first aspect. In this case, since the first ratchet pawl 36a is engaged with the ratchet teeth 33a of the ratchet gear 33, the ratchet gear 33 is allowed to rotate in the other direction (the direction of arrow B in the figure). However, rotation in one direction (the direction of arrow A in the figure) is restricted (blocked). When the operation unit 21 is positioned at the “weak” position from this state, as shown in FIG. 10, the engagement piece 41 is rotated in one direction, and the head 41 b of the engagement piece 41 is moved to the cam member 36. The cam member 36 is positioned at the second position by engaging with the second engaging portion 36e. This state is the second aspect. In this case, since the second engaging portion 36e is engaged with the ratchet teeth 33a of the ratchet gear 33, the ratchet gear 33 is allowed to rotate in one direction (the direction of arrow A in the figure). However, rotation in the other direction (the direction of arrow B in the figure) is restricted (blocked).

  Next, a method for adjusting the coupling force of the display device 16 with a touch panel to the housing 11 will be described. When the connection force of the display device 16 with the touch panel to the housing 11 is increased, the user first places the operation unit 21 at the “strong” position (first mode). Thereby, the ratchet mechanism 34 restricts the rotation of the ratchet gear 33 in one direction (the direction of arrow A in the figure). Then, the user rotates the display device 16 with a touch panel in one direction (the direction of arrow A in the figure). At this time, since the rotation of the ratchet gear 33 in one direction is restricted, the female screw 16i of the first base wall 16e of the display housing 16c moves relative to the male screw 26a of the first shaft member 26. Thus, the first shaft member 26 is moved in one of the axial directions (rightward in FIG. 6) while rotating. Thereby, the space | interval of a pair of spring support part 11i, 31a becomes narrow, the spring 25 is compressed, and the connection force of the display apparatus 16 with a touch panel with respect to the housing | casing 11 becomes large compared with the rotation before the display apparatus 16 with a touch panel. Furthermore, when it is desired to increase the connecting force of the display device 16 with a touch panel to the housing 11, the user rotates the display device 16 with a touch panel in the other direction (direction of arrow B in the figure). At this time, since the ratchet gear 33 is allowed to rotate in the other direction, the first shaft member 26 and the rotation of the display device 16 with a touch panel are caused by the friction of each part, as the display device 16 with the touch panel rotates. The ratchet gear 33 rotates. At this time, since the spring 25 is not deformed, the urging force of the spring 25 is maintained without being changed. Then, the user rotates the display device with a touch panel 16 in one direction again. Thereby, the connection force of the display device 16 with a touch panel to the housing 11 is further increased. In this way, the user can increase the connecting force of the display device 16 with a touch panel to the housing 11 and position the display device 16 with a touch panel at a desired position for use.

  On the other hand, when weakening the connection force of the display device 16 with the touch panel with respect to the housing 11, the user first positions the operation unit 21 at the “weak” position (second mode). Thereby, as shown in FIG. 10, the ratchet mechanism 34 restricts the rotation of the ratchet gear 33 in the other direction (the direction of arrow B in the figure). Then, the user rotates the display device with a touch panel 16 in the other direction (the direction of arrow B in the figure). At this time, since the rotation of the ratchet gear 33 in the other direction is restricted, the female screw 16i of the first base wall 16e of the display housing 16c moves relative to the male screw 26a of the first shaft member 26. Thus, the first shaft member 26 is moved in the other axial direction (left direction in FIG. 6) while rotating. Thereby, the space | interval of a pair of spring support part 11i, 31a becomes wide, the spring 25 expand | extends, and the connection force of the display apparatus 16 with a touch panel with respect to the housing | casing 11 becomes small compared with the rotation before the display apparatus 16 with a touch panel. Furthermore, when it is desired to reduce the connecting force of the display device 16 with a touch panel to the housing 11, the user rotates the display device 16 with a touch panel in one direction. At this time, since the rotation of the ratchet gear 33 in one direction is allowed, the first shaft member 26 and the rotation of the display device 16 with the touch panel are caused by the friction of each part in accordance with the rotation of the display device 16 with the touch panel. The ratchet gear 33 rotates. At this time, since the spring 25 is not deformed, the urging force of the spring 25 is maintained without being changed. Then, the user rotates the display device 16 with the touch panel in the other direction again. Thereby, the connection force of the display device 16 with a touch panel to the housing 11 is further reduced. Thus, the connection force of the display device 16 with a touch panel with respect to the housing 11 is weakened, and the display device 16 with a touch panel can be easily rotated to the retracted position. Thereby, the user can open the printer cover 13 easily.

  As described above, the adjustment mechanism 24 of the present embodiment increases the biasing force of the spring 25 in conjunction with the rotation of the display device 16 with a touch panel in one direction (the direction of the arrow A), and the display device with a touch panel 16. The first direction that maintains the biasing force without increasing the biasing force of the spring 25 in the rotation in the other direction (the direction of the arrow B) and the rotation in the other direction of the display device with a touch panel 16 are interlocked with the rotation in the other direction. Thus, the biasing force of the spring 25 can be reduced, and switching to the second mode in which the biasing force of the spring 25 is held without reducing the biasing force of the spring 25 when the display device 16 with the touch panel is rotated in one direction can be switched. is there. Therefore, the connecting force of the display device 16 with the touch panel to the housing 11 is adjusted by a relatively easy operation of turning the display device 16 with the touch panel by setting the adjustment mechanism 24 to the first mode or the second mode. be able to. Thus, in this embodiment, the connection force of the display device 16 with a touch panel to the housing 11 can be adjusted without using a special tool.

  The present invention is not limited to this embodiment, and various other embodiments can be adopted without departing from the gist of the present invention. For example, the spring 25 is not limited to a leaf spring but may be a coil spring or the like.
