  However, the above-described pedestal for a thin display device can secure a sense of stability when installed stationary on a floor surface or the like, but has not yet achieved a sense of stability during movement. In other words, when the display device is moved, there is a risk of falling because of the poor balance of the entire device during the movement.

  Accordingly, the present invention has been made in view of the above-mentioned problems of conventional display devices, and an object of the present invention is to provide a new and improved display device that can ensure a sense of stability during movement. It is to be.

  In order to solve the above problems, according to an embodiment of the present invention, a display unit having a display screen for displaying image information, and the display unit is supported so as to stand up and can be moved in a substantially horizontal direction. The display device includes a pedestal unit including moving wheels for supporting the display unit, and the pedestal unit supports the display screen of the display unit in a substantially vertical direction and moves the display unit in a substantially vertical direction. A support mechanism portion provided with a moving member, a mounting table on which an electronic device is mounted and a horizontal moving member that moves the electronic device in a substantially horizontal direction, a support mechanism portion supported in an upright state, and a mounting table A base having a space portion that can be installed, and an interlocking mechanism portion that performs movement of the electronic device in the substantially horizontal direction by the horizontal movement member in conjunction with movement of the display portion in the substantially vertical direction by the lifting and lowering movement member. Equipped with interlocking mechanism part When the moving member moves the display unit in the upward direction, the horizontal moving member moves the electronic device inward of the base, and when the moving member moves the display unit in the downward direction, the horizontal moving member The display device is characterized in that the electronic device is moved in the outward direction of the base.

  By adopting such a configuration, when the display device is moved, the display unit is lowered to lower the center of gravity, and the electronic device mounting table is moved away from the base so that the display device is stationary. The center of gravity of the entire display device is moved away from the position of the normal display unit, and the center of gravity is moved to the center of the entire display device. For this reason, since the balance of the whole display apparatus at the time of the movement of a display apparatus is stabilized, the fall of a display apparatus can be suppressed at the time of the said movement.

  At this time, in the above-described embodiment, the up-and-down moving member may include an up-and-down moving elastic member that presses the display unit at the position of the highest point in the up-and-down moving range of the display unit.

  With this configuration, when the display unit is moved downward, the display unit is raised by the pressing force of the elastic member for moving up and down such as a contracted gas spring when the display unit is returned to the original position. It is possible to easily return the mounting table on which an electronic device such as a printer is moved to the original position where the electronic device can be easily operated.

  At this time, in the above-described embodiment, the interlocking mechanism unit may include an inclined member that is coupled to the mounting table in an oblique direction and contacts a part of the display unit.

  With such a configuration, when the display unit is moved downward, a part of the force applied to the display unit is transmitted to the inclined member, so that the mounting table on which the electronic device such as a printer is mounted can be a gas spring or the like. This is moved backward against the pressing force of the elastic member for horizontal movement. Therefore, the vertical movement of the display unit and the horizontal movement of the printer can be linked.

  At this time, in the above-described embodiment, the inclined member may be integrally formed on the surface of the electronic device.

  In this way, by adopting a configuration in which the rail serving as the inclined member is connected to the mounting table via the main body of the electronic device such as a printer, there is no need to separately provide another member having an inclined surface. Can be

  At this time, in the above-described embodiment, the mounting table may be provided with an elastic member for horizontal movement that presses the electronic device in the inner direction of the base substantially parallel to the horizontal movement member.

  With such a configuration, when the display unit is moved down and then returned to the original position, an electronic device such as a printer is used by the pressing force of the elastic member for horizontal movement such as a contracted gas spring. A part of the force applied to the mounting table on which the device is placed is transmitted to the inclined member, and the display unit can be easily moved up and returned to its original position.

  At this time, in the above-described embodiment, the interlocking mechanism unit is engaged with the pulley rotatably supported on the top side of the support mechanism unit, and the rotational driving force of the pulley causes the display unit to move in a substantially vertical direction. It is good also as providing the rope-shaped member for converting into the driving force which moves, and the driving force which moves an electronic device to a substantially horizontal direction.

  In this way, by rotating the pulley, the display unit support member serving as the up-and-down moving member and the mounting table driving gear serving as the horizontal moving member are driven through the rope-like member engaged with the pulley. By doing so, when the display device is moved, the display unit is lowered to lower the center of gravity, and the mounting table of the electronic device can be moved away from the base. For this reason, the center of gravity of the entire display device can be moved away from the position of the normal display unit installed stationary, and the center of gravity can be moved to the center of the entire display device. The overall balance can be stabilized, and the display device can be prevented from falling during the movement.

  At this time, in the above embodiment, the display portion is wound around the shaft portion when the display screen is used, and is wound from the shaft portion to protect the surface of the display screen when the display screen is not used. A take-off screen may be provided.

  By adopting such a configuration, the display screen can be protected from an unexpected impact or the like when the display device is not used when the display device is moved.

  At this time, in the above-described embodiment, the lower end side of the display unit is engaged with the engagement unit provided on the base side when the display unit is moved down to the position of the lowest point in the up-and-down movement range. And it is good also as providing the locking member fixed with respect to this base.

  By adopting such a configuration, it is possible to prevent the display unit from being unexpectedly raised during the movement of the display device, causing the balance of the entire display device to be lost and the display device from falling down.

  As described above, according to the present invention, when the display device is moved, the display unit is lowered to lower the center of gravity, and when the display unit is lowered, that is, when the display device is moved, the electronic device is placed on the mounting table. By moving the display device away from the table, the center of gravity of the entire display device is moved away from the display unit and moved to the center of the entire display device, thereby stabilizing the balance of the entire display device. Suppress falls.
