Abstract

PURPOSE:To facilitate the fine adjustment of a display angle and to improve operability by constituting the above structure in such a manner that an extruding member screwed to a knob advances to turn a freely rotatably supported display device when the knob is turned. CONSTITUTION:The knob 30 is rotated counterclockwise viewed from the rear surface side of the display device when the display angle of this device is going to be changed. The extruding rod 35, then, advances toward the left and presses the bottom end of a fixing bracket as the knob 30 is fixed by a nut. Then, the fixing bracket 20 turns clockwise around a shaft 25 as the axis of rotation by overcoming the force of a spring 27. The display device 1 turns integrally clockwise as well. The knob 30 is rotated clockwise when the display angle is going to be returned. The extruding rod 35, then, retreats toward the right and, therefore, the fixing bracket 20 is turned counterclockwise by the energizing force of the spring 27 and the display device 1 is integrally turned as well. The fine adjustment of the display angle of the display device is freely executed in this way and the operability is improved.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to the installation structure of a display device that displays the amount of money placed at a cash register in a store and can change the display angle, and particularly relates to a stand type and a desktop type display device. This invention relates to an installation structure for a display device suitable for use in both □ and □.

[Conventional technology]

FIG. 5 is a side sectional view showing the installation structure of a conventional display device, and shows the case of a stand type display device. In the figure, a display device designated by reference numeral 50 is composed of an upper case 51 and a lower case 52, and a display section 53 on which monetary amounts and the like are displayed is provided on the front surface of the upper case 51. A mounting boss 54 with a screw hole formed on the back side of the lower case 52
and 55 are provided. A fixing bracket 56 is provided with a pair of hinges 57, and is fixed to the boss 54 with screws 58. A ratchet gear 59 is integrally formed with a shaft 60 rotatably supported by the hinge 57. A click spring 61 is fixed to the boss 55 by a screw 63, and a click portion 62 at the tip engages with the ratchet gear 59. Reference numeral 65 denotes a box-shaped support stand that supports the display device 50 at an appropriate height and at the same time fixes the synopsis 60 at both ends.

In such a configuration, when changing the angle of the display device 50 to make it easier to view the display device 50, when the display device itself is rotated clockwise, the ratchet gear 59
By the moderation mechanism of the click spring 61, the display device 50
can be rotated around the shaft 60 to change the display angle in moderation.

[Problem to be solved by the invention]

However, in the conventional installation structure described above, the display angle relies on a click mechanism using a ratchet gear and a click spring, so it is difficult to finely adjust the display angle of the display device, and the display is prone to wobbling. It may also rotate if you accidentally touch the device. Further, positioning when fixing the display device to the initial position of the support stand 65 is troublesome, and operability is poor because the display device itself must be operated.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a display device installation structure with excellent operability that allows fine adjustment of the display angle of the display device.

[Means to solve the problem]

The installation structure of the display device according to the present invention includes a fixed bracket attached to the back surface of the display device, a shaft that serves as a pivot axis for the fixed bracket, and a shaft that is wound around the shaft to impart rotational sliding properties to the fixed bracket. a support stand that is freely separable and has a spring that supports the shaft, a guide portion formed inside the support stand that is movable back and forth; a push-out member provided with a push-out member; a knob that is fitted from the outside of the back of the support stand and has a screw that is threaded into a screw hole of the push-out member; and a nut that fixes the knob on the back of the stand. .

[Effect]

In the present invention, when the knob is operated and rotated, since the knob is fixed to the support stand with a nut, the knob only rotates, and the extrusion member having the screw hole that is engaged with the screw of the knob moves. The tip presses the fixed bracket, causing the display device to rotate about the shaft against the biasing force of the spring.
