[0006]
[Problems to be solved by the invention]
However, the thing of the said patent document 1 prohibits the keyboard input when the display part is almost closed, and this is effective when a foreign object is caught between the display part and the keyboard. The display part was not open, and input was not prohibited while turning the display part upside down with another rotating shaft.
[0007]
The present invention prevents erroneous input caused by inadvertently touching the display unit from when the display unit is opened to a predetermined angle by the first rotation axis until the display unit is turned over by the second rotation axis. The purpose is to provide information devices that can be used.
[0008]
[Means for Solving the Problems]

A projecting portion projecting from the second plate, and through the second bearing provided in the plate portion while penetrating the plate portion. A second cam plate having a second hole portion rotating shaft is fitted, has a detection switch to disable input of said input means provided in said display surface, the display unit the first It said pin presses the detection switch in conjunction from the body about the pivot axis to the first pivot to reach the neutral point where the display unit is rotated about 90 degrees in the direction away, the display unit The input of the input means is invalidated.
[0009]
When the display unit is opened to the neutral point with such a configuration, the pin implanted in the first cam plate that fits the first rotation shaft presses the detection switch in conjunction with the first rotation. As a result, the input means of the display unit becomes invalid, and this acts to prevent erroneous input due to contact with the display unit during that time.
[0010]
Further, in this basic configuration, the protrusion provided in the first cam plate is urged, a spring member having a recess is provided inside the arm, and the protrusion engages with the recess at the neutral point. Thus, it is also possible to provide a structure that gives a click feeling , whereby the display unit with the first rotation axis as the center acts so that the user can detect the click feeling simultaneously with the rotation to the neutral point .
[0011]
In any one of the information devices described above, after the first rotation, the second display unit rotates the display unit 180 degrees around the second rotation axis with a click feeling at the neutral point. may it configuration der to allow the rotation. With this configuration, the display unit is rotated 180 degrees around the second rotation axis and turned upside down, and the input means is invalid until this state, so that erroneous input due to contact with the display unit during that time is prevented. Act on .
[0012]
In the information device having any one of the above-described configurations, a configuration that enables a third rotation that causes the display unit to approach the body about the first rotation axis after the second rotation. It may be. With this configuration, the input unit is ineffective from the time when the display unit reaches the neutral point to the start point and end point of the second rotation, and maintains a state in which no erroneous input occurs even if the input unit is touched. In this manner, the third rotation causes the input means of the display unit to be input .

Can be rotated around the center, and if it is held by hand, it rotates 180 degrees in the direction of arrow B as shown in FIGS.
[0018]
When the rotation of 180 degrees is finished, the liquid crystal display unit 5 to which the touch panel 4 of the display unit 2 is attached turns away from that in FIG. 1B, and from this state, the arrow C around the first rotation shaft 3 is set. A third rotation in the direction is possible. FIG. 1E shows a state where the third rotation is finished. The liquid crystal display unit 5 with the touch panel 4 mounted on the surface faces the surface, and input can be made to the touch panel 4 in this state.
[0019]
2A is a plan view of the rotating mechanism, FIG. 2B is a side view including a partial cross-section, and FIG. 2C is a partial view of the cam plate B. A washer 12 integrally formed with a shaft 12a is attached to the substrate 11 for attachment to the main body 1 of FIG. 1 by caulking or the like, and the U-shaped arm 14 integrated with the bearing A13 or caulking by the shaft 12a. The cam plate A15 is firmly fitted to the tip of the shaft 12a by the center hole 15a so that the arm 14 does not fall off. The cam portions 15b and 15c of the cam plate A15 are engaged with the protrusions 14c of the arm 14, thereby restricting the rotation of the arm 14 to a range of 180 degrees clockwise from the illustrated position in FIG.
[0020]
A bearing B16 and a bearing C17 are fixed to both wings 14a and 14b bent at a right angle of the arm 14 by caulking or the like, respectively, and the shafts 18a and 19a of the display unit mounting brackets 18 and 19 are penetrated to the shaft 18a. The hole 20a of the cam plate B20 and the hole 21a of the retaining plate 21 are firmly fitted to the shaft 19a, and the display plate mounting brackets 18 and 19 are rotatably held. The display unit 2 is fixed to the holes 18b and 19b. The shaft 18a and the shaft 19a are configured to be orthogonal to the shaft 12a.
[0021]
Further, as shown in FIG. 2 (c), a part of the entire circumference of the cam plate B20 has a protruding portion 20b, which gives a click feeling when engaged with the concave portion 21a of the spring 21 fixed to the arm 14. is there. A pin 22 is provided on the outer peripheral side surface of the cam plate B20 so as to contact the actuator 23a of the detection switch 23.
[0022]
When the rotating mechanism is attached to the main body 1, the shafts 18 a and 19 a are installed so as to be parallel to one side of the main body 1 to serve as the first rotating shaft, and the shaft 12 a orthogonal thereto is the second rotating shaft. And
[0023]
In FIG. 3, the input from the touch panel 4 is input to the control circuit 32 through the gate circuit 31 that is normally open. The input of the detection switch 23 is applied to the gate circuit 31. When the detection switch 23 is turned on, the gate circuit 31 is closed and the output of the touch panel 4 is not input to the control circuit 32.
[0024]
The operation of the information device of the present embodiment configured as described above will be described below. In a normal use state, the display unit 2 is opened so that the angle is as shown in FIG. 1A, and input is made from the keyboard 1a and the touch panel 4. As another form of use in this information device, as shown in FIG. 1 (e), only the touch panel 4 can be put on the surface and input can be used. Will be described.
[0025]
First, when the display unit 2 is opened from the storage state, or when the display unit 2 is made vertical (approximately 90 degrees with respect to the main body 1) as shown in FIG. 1B from the use state of FIG. In the first rotation), the protrusion 20b of the cam plate B20 engages with the recess 21a of the spring 21 and stops with a click feeling. At this time, the axis 12a coinciding with the second rotation axis is vertical. At the same time, since the pin 22 presses the actuator 23a of the detection switch 23, the detection switch 23 is turned on, the gate circuit 31 is closed, and the input from the touch panel 4 is not input to the control circuit 32. For this reason, even if the hand which is going to rotate the display part 2 touches the surface of the touch panel 4 accidentally, it will not input erroneously.
[0026]
In this state, the display unit 2 is held and rotated as indicated by an arrow B in FIG. Since the surface of the display unit 2 remains vertical during the rotation, the pin 22 keeps pressing the actuator 23a of the detection switch 23, and the output of the touch panel 4 does not enter the control circuit 32. When the rotation of the display unit 2 with respect to the shaft 12a is completed by the engagement of the cam 15c and the projection 14c, the pin 22 is engaged when the display unit 2 is to be folded as shown in FIG. When the gate circuit 31 recognizes the input of the output of the touch panel 4 away from the actuator 23a that has been provided to the control circuit 32, the touch panel can be input.
[0027]
As described above, in the present embodiment, by providing a detection switch that detects when the display unit 2 is vertical with the first rotation axis, the display unit is set to be vertical and the second rotation axis is around. While the display unit is rotated 180 degrees, the input from the touch panel can be invalidated, and even if the touch panel surface is touched accidentally while rotating about the second rotation axis of the touch panel, an erroneous input is generated. There is no.
[0028]
The click feeling can be given at the start point and the end point of the second rotation in the same manner as the click feeling at the neutral point of the display unit.
[0029]
Further, the gate circuit 31 is provided with a delay means for delaying the operation for a predetermined time when the detection switch 23 is switched from on to off. For example, if a delay of 0.5 seconds is given, the display unit is turned over. Prevents erroneous input due to touching the touch panel during operation while bringing it to the position shown in FIG. 1 (e) or from the position shown in FIG. 1 (b) to the position shown in FIG. 1 (a). be able to.
[0030]
(Embodiment 2)
Hereinafter, an information device according to Embodiment 2 of the present invention will be described with reference to the drawings. FIG. 4 is a perspective view for explaining how to use the information equipment in Embodiment 2 of the present invention, and FIG. 5 is a block diagram of the input circuit.
[0031]
In FIG. 4, the display unit 42 with respect to the main body 41 stands in a direction perpendicular to the direction of the arrow A by the first rotation shaft 43 along one side of the main body 41 and with respect to the first rotation axis. The display unit 42 is provided with a liquid crystal display unit 46 with a touch panel 45 mounted on the surface thereof, and is displayed below the display unit 42. A magnet 47 is embedded at one end, and magnetic detection sensors 48 and 49 such as reed switches are embedded at corresponding positions of the main body 41.
[0032]
In FIG. 5, the output of the touch panel 45 is input to the control circuit 52 via the gate circuit 51. The gate circuit 51 has a delay function. When the magnetic detection sensors 48 and 49 are turned on and the gate is closed, the output of the touch panel 45 is not given to the control circuit 52, and the magnetic detection sensors 48 and 49 are turned off. This state is maintained for a predetermined time, for example, 0.5 seconds.
[0033]
The operation will be described next. First, the display unit 42 is opened from the storage state until the display unit 42 becomes vertical in the direction of the arrow A around the first shaft 43, or the display unit 42 is returned to the vertical state from the use state as shown in FIG. At the neutral point, it stops with a click feeling in the same manner as in the first embodiment. At this time, since the magnet 47 is close to the magnetic detection sensor 48, the magnetic detection sensor 48 is turned on, the gate circuit 51 is closed, and the output of the touch panel 45 is not input to the control circuit 52. In this state, the display unit 42 is rotated around the second shaft 44. Although the magnet 47 moves away from the magnetic detection sensor 48, the gate is closed for a predetermined time (for example, 0.5 seconds) due to the delay function of the gate circuit 51. . When the rotation of 180 degrees is completed, the magnet 47 comes close to the magnetic detection sensor 49, and therefore, the delay function of the gate circuit 51 during the third rotation until the magnet 47 is folded to the state shown in FIG. Even if the touch panel 45 is accidentally touched during this time, no erroneous input will occur.
[0034]
As described above, in the present embodiment, in a state where the display unit is vertical by the first rotation shaft, the display unit can be rotated around the second rotation shaft, and at the start and end points of the rotation. By operating the detection switch and disabling the touch panel output when the detection switch is turned on and for a predetermined time after being turned off, erroneous input to the touch panel during that time can be avoided.
[0035]
Also in this embodiment, a click feeling can be given at the neutral point of the display unit, and a click feeling can be given at the start point and the end point of the second rotation in the same manner.
[0036]
In each of the above embodiments, an example of a notebook personal computer has been described. Can do.
