DISPLAY DEVICE, AND POS TERMINAL DEVICE

摘要

It is an object of this invention to provide a display device capable of easily adjusting the height thereof without providing an extension and contraction mechanism. The display device (1) of this invention includes: a casing (3); and a display unit (5) to be installed for use onto the casing (3), the casing (3) and the display unit (5) being available to directly couple to each other. A coupling structure between the casing (3) and the display unit (5) is changeable from a state in which the casing (3) and the display unit (5) are directly coupled to each other to a state in which the casing (3) and the display unit (5) are coupled to each other with a pole (7) having a columnar shape and separable along a center axis thereof, which is mounted between the casing (3) and the display unit (5).

主权项

1. A display device, comprising:
a casing; and a display unit to be installed for use onto the casing, the casing and the display unit being available to directly couple to each other, wherein a coupling structure between the casing and the display unit is changeable from a state in which the casing and the display unit are directly coupled to each other to a state in which the casing and the display unit are coupled to each other with a pole having a columnar shape and separable along a center axis thereof, which is mounted between the casing and the display unit, and the display unit is provided so as to be rotatable with respect to the casing both under the state in which the casing and the display unit are directly coupled to each other, and under the state in which the casing and the display unit are coupled to each other with the pole, the display device further comprising: a display unit-side coupling portion provided to the display unit, a casing-side coupling portion provided to the casing, available to rotatably couple to the display unit-side coupling portion. an upper coupling portion provided to one end portion of the pole available to rotatably couple to the display unit-side coupling portion, a lower coupling portion provided to another end portion of the pole available to insert and to be fixed to the casing-side coupling portion, and an intermediate coupling portion rotatably held by the display unit-side coupling portion, wherein the display unit-side coupling portion has a ring-like groove portion on the outer periphery thereof, the groove portion is provided to an outer periphery of the intermediate coupling portion. wherein the pole has a cylindrical shape, and the pole further comprises, on the inner periphery of the upper coupling portion, a ring-like pole-side coupling portion insertable into the ring-like groove portion, wherein the intermediate coupling portion is rotatably held by the pole through insertion of the ring-like pole-side coupling portion into the ring-like groove portion. wherein the intermediate coupling portion is rotatably held by the casing-side coupling portion and, the intermediate coupling portion is rotatably held by the upper coupling portion.
