Abstract

PROBLEM TO BE SOLVED: To prevent the generation of danger of shielding light beams by preventing the tip of finger from touching a display screen even when a hand is put on the upper face of a display part unconsciously by an operator by providing a hand rest part between the operating side outer periphery of the display part and the outside of input coordinate area of the display screen. SOLUTION: Inside a display part 1a, a display is constituted thin by using a plasma display, and a menu or the like is displayed on a display screen 2. Between the operating side outer periphery of this display part 1a and the outside of input coordinate area of the display screen 2, a hand rest part 8 is provided. Concerning the hand rest part 8, the upper face lengthwisely extended between both the left and right terminals of the display part 1a is formed semicylindrical, and warp-back bent from the bottom face toward the upside of the display screen 2 is provided. Thus, even when the operator puts one hand 7 on the upper face of the display part 1a unconsciously, the tip of finger turns downward and does not touch the display screen 2 since the palm is placed on the semicylindrical hand rest part 8 and even when the tip of finger is extended, the tip of finger does not touch the display screen 2 since there is the warp-back.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical input display device, and more particularly to a structure for preventing malfunction during operation.

[0002]

2. Description of the Related Art In an input display device using a flat display, an optical touch panel, etc., a menu (touch items, etc.) is displayed on a screen, and a plurality of light emitting elements and light receiving elements are provided on each of four opposite sides of the display surface. And are arranged in pairs, X,
At the Y coordinate, one element is sequentially emitted from each end to scan the light beam on the display screen, the coordinate position where the light beam is shielded is detected by a touch of a finger or the like, and a signal corresponding to the coordinate position menu is input. As shown in FIG. 4, in the input display device 1 in which the display screen is inclined, when the operator operates toward the display surface 2 of the menu, one hand 7 that is not operated is unconsciously hung on the upper surface of the display unit 1a. Often operated. Therefore, there is a problem that the fingertip touches the display surface 2 and blocks the light beam 5, which causes a malfunction when operated with another hand.

[0003]

In view of the above problems, in the present invention, even if the operator unconsciously puts one hand on the upper surface of the display unit, the fingertip may not touch the display surface, and the light beam may be blocked. It is intended to provide a non-input display device.

[0004]

According to the present invention, in order to solve the above-mentioned problems, an input display panel is mounted on the display section of the main body, and a plurality of input display panels are provided on each of the four opposite sides of the display surface of the input display panel. A pair of the light emitting element and the light receiving element are arranged at a constant interval, the light emitting elements of the X coordinate and the Y coordinate are sequentially made to emit light from the respective ends, and the light beam is scanned on the display surface. In the case of detecting a position, a handle portion is provided between the outer periphery of the operation side of the display unit and the outside of the input coordinate area of the display surface. Further, the handle portion has a semi-cylindrical upper surface, and is provided with a curved warp upward from the bottom surface to above the display surface. Further, the handle portion has a cylindrical shape, and a flat plate portion is provided so as to project forward from a contact portion with the display portion. Further, the handhold portion is made of a synthetic resin with antistatic property.

BEST MODE FOR CARRYING OUT THE INVENTION An input display panel is mounted on a display unit of a main body, and a plurality of light emitting elements and light receiving elements are arranged at regular intervals on opposite sides of four sides of a display surface of the input display panel. A light emitting element for X and Y coordinates is sequentially emitted from each end to scan a light beam on a display surface to detect a coordinate position shielded by a finger of the light beam. With the configuration in which the handle portion is provided between the periphery and the outside of the input coordinate area of the display surface, even if the operator unconsciously hangs one hand on the upper surface of the display portion, the fingertip does not touch the display surface, and the light beam The input display device does not shut off.

Embodiments of the input display device according to the present invention will be described in detail below with reference to the drawings. 1A is a perspective view of a main body of the input display device according to the present invention, FIG. 1B is a side view of a main part, and FIG. 2A is a side view of a main part showing a display surface.
3B is a top view, FIG. 3A is an enlarged view of an essential part showing one embodiment, and FIG. 3B is an enlarged view of an essential part showing another embodiment. 1 to 3, reference numeral 1 is a main body, and a plasma display panel (PDP) is provided in a display unit 1a, for example, as a display.
Is used to display a menu (touch item) or the like on the display surface 2. 3 is a light emitting element, for example, an LED
(Light emitting diode) is used, and the display surface 2 does not intersect 2
Plural sides are provided at appropriate intervals to emit infrared rays or the like that do not give a sense of discomfort to the eyes. Reference numeral 4 denotes a light receiving element, for example, a phototransistor is used, and is arranged corresponding to each light emitting element 3 on the side of the display surface 2 opposite to the side where the light emitting element 3 is arranged.

The light-emitting element 3 and the light-receiving element 4 are paired to emit light one by one from the ends at the X and Y coordinates, and the light beam 5 is scanned on the display screen. The light-shielded coordinate position is detected and a signal corresponding to the coordinate position menu is input to a required signal processing circuit.

Reference numeral 8 denotes a handle portion provided between the outer periphery of the operation side of the display portion 1a and the outside of the input coordinate area of the display surface 2. The handle portion 8 is provided at the left and right ends of the display portion 1a in the longitudinal direction. A semi-cylindrical shape is provided on the upper surface extending toward the upper side, and a curved warp 8a is provided above the display surface 2 from the bottom surface. Further, the handle portion 8 is made of a synthetic resin with antistatic property.

With the above structure, even if the operator unconsciously hangs one hand 7 on the upper surface of the display unit 1a, the palm rests on the semi-cylindrical hand-holding unit 8, so that the fingertip is directed downward, so that the display surface 2 is touched. No, and even if you extend your fingertips, it bends back 8a
Therefore, the fingertip does not touch the display surface 2.
