Abstract

PURPOSE:To prevent a display panel body from being broken by providing a separation detecting means and an oscillating range control means. CONSTITUTION:The information processor is equipped with the separation detecting means (detection button) 4 which detects the separation of a keyboard 3 from a processor main body 1 and the oscillation range control means (swing control member) 12 which restricts the oscillating range of the display panel body 2. Therefore, once the keyboard 3 is separated from the processor main body 1, the detection button 4 detects the separation of the keyboard 3 and the oscillating control member 12 restricts the oscillating range of the display panel body 2 in response. Thus, when the keyboard 3 is separated, the oscillating range of the display panel body 2 is restricted, so the display panel body 2 does not strike on an obstacle even if the obstacle existents on the place where the keyboard 3 existents in the nonseparation state. Consequently, the display panel body 2 is prevented from being damaged.

Embodiments FIGS. 1 to 18 show various embodiments of the present invention.
Will be explained. A first embodiment of the information processing apparatus will be described with reference to FIGS. FIG. 1 is a cross-sectional view showing an embodiment of the present invention, in which 1 is a processing apparatus main body, 2 is a display panel, 3 is a keyboard, 4 is a keyboard convex portion for connecting the keyboard 3 to the processing apparatus main body 1, 5 Is a concave portion of the processing device main body for receiving the keyboard convex portion 4, 6 is a detection button for detecting whether the keyboard 3 and the processing device main body 1 are connected or separated, and 7 is a L for transmitting displacement of the detection button 6. A type rod, 8 is a spring for urging the detection button 6 connected to the L type rod 7 in the protruding direction into the processing device main body recess 5, 9 is a rod for transmitting the displacement of the L type rod 7, and 10 is a rod 9 Of the displacement conversion rod for converting the linear displacement of the above into rotational displacement, 11 is the displacement conversion rod 1
A displacement conversion rod column that rotatably supports 0 and a rocking regulating member 12 that is joined to the rotating shaft of the display panel 2 and that rotates with the rocking of the display panel 2. This rocking regulating member 12
When the displacement conversion rod 10 rotates, the displacement rod 1
A protrusion is provided which is engaged with the end portion of 0 to regulate the swing range of the display panel 2.

As shown in FIG. 1, when the keyboard 3 is connected to the processing apparatus main body 1, the keyboard convex portion 4 is inserted into the processing apparatus main body concave portion 5, and the detection button 6 is attached to the processing apparatus main body 1. Is pushed into the back of the. The displacement conversion rod 10 is in a state in which the end portion of the displacement conversion rod 10 and the protrusion of the swing restriction member 12 do not engage with each other even if the display panel 2 swings. Therefore, the display panel 2 is
The display panel 2 can be freely swung within a swing range restricted from the viewpoint of the mounting structure.
Note that the swing range at this time is, specifically, as shown in FIG. 3, at a position 35 ° inward from the vertical line ((c) in the figure).
From the state) to the place where the keyboard 3 comes into close contact (downward with respect to the horizontal plane by 15 °, state (a) in the figure).

When the keyboard 3 is separated from the processing apparatus main body 1, as shown in FIG. 2, the keyboard convex section 4 comes out of the processing apparatus main body concave section 5, and the detection button 6 is pushed by the force of the spring 8 into the processing apparatus main body concave section. Project to 5. Note that, as shown in FIGS. 1 and 2, the detection button 6 is formed so that the base end side is larger than the protruding end side, and the detection button 6 itself does not pop out. Due to the protrusion of the detection button 6, the L-shaped rod 7 and the rod 9 are displaced leftward in FIG. Upon receiving this displacement, the displacement conversion rod 10 rotates to the right, and is displaced to a position where the end portion of the displacement conversion rod 10 and the protrusion of the swing restriction member 12 can engage with each other.
Therefore, when the display panel 2 is oscillated greatly, the end portion of the displacement conversion rod 10 and the protrusion of the swaying regulation member 12 are engaged with each other, and the display panel 2 is further moved from the engaged position. It becomes impossible to rock. That is, when the keyboard 3 is separated from the processing apparatus main body 1, the swing range of the display panel 2 is restricted, and the swing range is specifically, as shown in FIG. The range is from the state (state (c) in the figure) to the position 20 ° above the horizontal plane (state (b) in the figure). In addition,
In the state (b), the distance between the lower surface of the display panel 2 and the floor surface is
It is about 135 mm.

When the information processing apparatus of this embodiment is stored, as shown in FIG. 4A, the processing apparatus main body 1, the display panel 2, and the keyboard 3 are integrated. When using, open the display panel 2 as shown in FIG.
In many cases, the keyboard 3 is removed and the user works in a position where the user can easily use it. Even if the display panel 2 is closed during use in such a form, the display panel 2 cannot be swung at a distance of 135 mm from the floor surface. Even if a foreign object such as a coffee cup or a glass is placed, it does not come into contact with the coffee cup or the like, and the display panel 2 can be prevented from being damaged.

Under normal operating conditions, when the keyboard 3 is separated, the swing range of the display panel 2 is the range from the state (c) to the state (b) in FIG. 3, so there is no problem. It may be considered that there is a case in which it is desired to use in the range from the state () to the state (a). In such a case, the detection button 6 is pushed by a thin object such as a fingertip of a hand or a ballpoint pen to disguise the connected state of the keyboard 3 so that the display panel can be swung within the swing range from the state (c) to the state (a). 2 can be used.

In this embodiment, (b) in FIG.
In this state, the distance between the bottom surface of the display panel 2 and the floor surface is about 135
Although it is set to about mm, this distance may be set to about 100 mm. Further, in the present embodiment, the transmission of the displacement of the detection button 6 is transmitted by using the rods 7 and 9, but it is not necessary to use any rod, and it can be realized by using a wire. Also,
It is an important point to prevent the malfunction when the button 6 is attached to the back side of the processing apparatus main body 1, not to the upper surface thereof.

In this embodiment, in order to protect the display panel when the keyboard 3 is separated, the floor surface and 135 m are protected.
Although the display panel 2 is locked and stopped at the position of m, a user who operates for the first time without reading the manual may not know why it is locked and may forcefully close the display panel 2 and destroy the open / close lock mechanism. There is. In order to prevent this, it is possible to make an alarm sound when locking. This configuration will be described with reference to FIGS. 5 and 7.

In FIGS. 5 and 7, 13 is a contact conductor provided at the end of the displacement conversion rod 10, 14 is a contact conductor provided on the protrusion of the swinging restricting member 12,
Reference numeral 15 is a conductive wire, 17 is a buffer, and 18 is an output of the buffer 17. To make an alarm sound,
There are cases where it is kept on all the time and cases where it is kept for a certain time after locking. Depending on the user, there is a case where the user wants to use it while locking it, and in consideration of this, a method of issuing an alarm sound for a certain period of time is preferable. It is possible to make the parts common and to reduce the size and cost of the device by providing only the one that transmits the lock information, rather than having a dedicated timer to output the alarm sound for a certain period of time. Therefore, here, as shown in FIG.
The output 18 of 7 is connected to the port of the main body of the apparatus or the interrupt request line, and the lock state is detected by the scan and the interrupt by the program, and the program for issuing the alarm sound for a certain time is executed.

In the locked state, it is necessary to generate an alarm sound even if the main power supply is off. To realize such a function, a sub power supply (backup power supply) is, of course, necessary, but an interrupt request line for transitioning the controller from the low power consumption status to the normal operation status is supplied. The output 18 of the buffer 17 may be connected. Although the contact conductors 14 and 15 are used here to detect the locked state,
For example, a micro switch 16 may be used as shown in FIG.

In the embodiment described with reference to FIGS. 1 to 4, the lock is realized by using a rod, a wire or the like.
The present invention is not limited to any method using them. Therefore, with reference to FIGS. 8 and 9, a system in which the display panel body 2 is directly locked will be described as a second embodiment.
This will be described below. In FIG. 8 and FIG. 9, 401 is a rocking restricting member that is swingably provided in the processing apparatus main body 1, 402 is a hinge that abuts on the rotation axis of the rocking restricting member 401, and 403 is when the keyboard 3 is not attached. Further, it is a spring that pushes up the swing restriction member 401 to a position where the swing range of the display panel 2 can be restricted. When the keyboard 3 is attached to the processing apparatus main body 1, as shown in FIG. 8, the swinging restricting member 401 cannot swing because the keyboard 3 is attached, so that the swinging range of the display panel 2 is limited. Is not in a position where the control can be performed, and the swing range of the display panel 2 is not controlled. When the keyboard 3 is separated from the processing apparatus main body 1, the rocking restricting member 401 becomes rockable and pushed up by the spring 403 so that the rocking range of the display panel 2 can be restricted. It should be noted that in the present embodiment, the separation detecting means is composed of a swing restricting member 401, the swing of which is restricted by mounting and separating the keyboard 3,
The rocking range restricting means includes a rocking member 401, a hinge 402, and a spring 403.

Even in a portable workstation having a flat display panel display, it is relatively difficult to tilt the display panel because the display panel becomes far from the operator when the keyboard is used separately. Also,
If you move your head to tilt from the position to operate, the angle with the display panel will differ between immediately after tilting and when you tilt and return your head to its original position, so it is difficult to obtain the optimum tilt angle etc. I have a problem. Therefore, as a third embodiment, one in which the display panel is driven by an electric motor according to an instruction from a keyboard or a mouse will be described with reference to FIGS.
Will be explained.

In FIGS. 10 and 11, 101 is a stepping motor for swinging the display panel 2, and 1 is a stepping motor.
Reference numeral 02 is a timing pulley provided on the rotation shaft of the stepping motor, 103 is a timing pulley provided on the rotation shaft of the display panel 2, 104 is a timing belt hung on the timing pulleys 102 and 103, and 105 is a light shielding plate. A holding disk, 105a is a lower limit light-shielding plate for indicating a lower swing limit when the keyboard 3 is separated, 105b is an upper-limit light shield plate for indicating an upper swing limit of the display panel 2, and 106 is a photo interrupter.
Further, in FIG. 12, 16 is a micro switch for detecting separation of the keyboard 3, and 107 is a memory in which various programs for operating the CPU are stored.
Here, in the memory 107, the display panel control window is expanded on the display panel as shown in FIG. 13 by an instruction from the keyboard 3 or the mouse, and when the arrow shown there is instructed by the keyboard 3 or the mouse, stepping is performed. A program for outputting a drive signal to the motor 101 is stored. Note that FIG. 13 shows two types of display panel control window images. Also, FIG.
In FIG. 3, 201 is an outer frame of the window, 202 is a click area instructing to close, and 203 is a click area instructing to open.

In order to connect the rotating shaft of the stepping motor 101 and the rotating shaft of the display panel 2, gear connection (including worm gear etc.), direct connection, etc. can be considered without using any timing belt or the like. However, the timing belt is advantageous in order to reduce operation noise, obtain a sufficient static torque so that the display panel does not drop, and to endure forward / reverse bidirectional rotation. The static torque of the stepping motor 101 is sufficient to support the display panel 2 without a brake, and is within a range in which the display panel 2 can be directly opened and closed by hand. The flow of the motor control program is shown in FIG. When the user feels that the tilt angle of the display panel 2 is not appropriate and wants to move the display panel 2 upward (in the opening direction), the click area 203 is clicked. The CPU (main CPU of the workstation or a small CPU called a controller for controlling the I / O system) recognizes this (step 1) and judges whether the display panel 2 is located at the upper limit or not. (Step 2). When not at the upper limit,
A command is sent to the stepping motor controller to send a pulse for rotating the stepping motor 101 forward (step 3). The stepping motor controller outputs a pulse for forward rotation to the motor driver according to this command, and the motor driver gives a pulse of electric power sufficient to move the motor 101. If it is determined in step 1 that the click area 203 is not clicked, or if it is determined in step 2 that it is the upper limit, the click area 20
It is determined whether or not 2 is clicked (step 4). If the click area 202 is clicked and the display panel 2 is not located at the lower limit, a command is sent to the stepping motor controller to send a pulse for rotating the stepping motor 101 forward (step 6). When it is determined in step 4 that the click area 202 is not clicked, or when it is determined in step 5 that it is the lower limit, the process ends.

Although the keyboard 3 which can be separated from the main body 1 of the processing apparatus has been described above, a keyboard to which the present invention is applied cannot be separated as a fourth embodiment.
From FIG. 18 onward will be described. FIG. 16 is a schematic circuit block diagram of the present embodiment, where 301 is an obstacle sensor for detecting whether or not there is an obstacle on the front side of the display panel 2, 30
Reference numeral 2 is a speaker for notifying when the obstacle sensor 301 detects an obstacle, 101 is a stepping motor for rocking the display panel 2, 105 is a light shielding plate holding disk, and 106 is a photo interrupter. Here, as the obstacle sensor 301, from the display panel 2 to the foreign substance, it is possible to use the interference with the reflected wave by using infrared rays or ultrasonic waves, or to block the light by the pair of the light emitting element and the light receiving element. Is used to measure the distance and presence of. However, in addition to such non-contact detection of obstacles, a display panel 2 having, for example, a transparent dielectric between two thin transparent electrodes is provided.
By forming a capacitor with this, a method to detect the change in capacitance due to the deformation of the dielectric when contacting an obstacle,
There is no problem even if the method of detecting the change in the current value due to the increase in the load on the motor is adopted. Further, the light shielding plate holding disk 10
5 is basically the same as that described in the third embodiment, but the lower limit light-shielding plate provided therein does not represent the lower swing limit when the keyboard 3 is separated, and the display panel This is for indicating that the keyboard 2 and the keyboard 3 are in contact with each other and are in the stored state. Further, in the memory 303, in addition to a general program for operating the device, a program for executing the flowcharts shown in FIGS. 17 and 18 is also stored.

The operation of this embodiment will be described with reference to the flow charts shown in FIGS. As shown in FIG. 17, when the obstacle sensor 301 detects an obstacle (step 10), an alarm indicating that there is an obstacle is output from the speaker 302 for a certain period of time (step 11),
Immediately ends. That is, when there is an obstacle, an alarm is issued and the display panel 2 cannot be swung (the swing is restricted). If there is no obstacle, according to the judgment as to whether the click area 202 or the click area 203 is clicked (steps 12, 1).
3) Output forward or reverse rotation pulses to the stepping motor 101. Thus, before the pulse is sent to the motor 101, the data from the obstacle sensor 301 is scanned to prevent the display panel 2 from being destroyed.

UNIX workstations, etc.
When ending the operation, the power cannot be turned off immediately, so the power is turned off by software. When the display panel 2 is automatically closed at the end of the shutdown process, it is convenient because the operator's time can be saved as compared with closing the display panel 2 after confirming the completion of the shutdown process and power-off. FIG. 18 shows a flowchart relating to this. When the operator gives an instruction to power off by clicking the mouse or the like, first, a shutdown process such as file saving is performed (step 21). Next, the presence or absence of an obstacle is confirmed (step 22), and if there is an obstacle,
The power is turned off (step 25) and the process ends. . If there is no obstacle, the motor is rotated in the reverse direction (step 23) and the display panel 2 starts to be closed. When the obstacle is detected on the way, it is stopped at the same angle and the power is cut off (step 25), and the obstacle is detected on the way. Otherwise, when the photo interrupter 106 detects the lower limit by the lower limit light-shielding plate 105a (step 24), the power is cut off (step 25). The detection of the lower limit indicates that the display panel 2 is completely closed.

Further, in the pursuit of convenience, a workstation having a sensor on the back surface of the display panel 2 and automatically opening the display panel 2 by software at the time of start-up by a power ON switch is also conceivable. In this case, when an obstacle is detected, it stops at that angle and starts operating normally. If no obstacle is detected, the swing angle at the time of the previous shutdown processing is reproduced to start the operation. It is also possible to start the operation by opening the display panel at the angle set by the user (preserved at the time of shutdown) depending on the user name to log in. In order to reproduce the swing angle of the display panel 2 in this way, it is necessary to store the swing angle during the shutdown process or the swing angle designated by the user in the memory 303. Although the keyboard 3 is not separable in the present embodiment, it is needless to say that the display panel 2 can be prevented from being damaged even if the present embodiment is applied to the separable keyboard 3. .

According to the present invention, the swing of the display panel is restricted by detecting the keyboard separation or the presence or absence of an obstacle, so that the display panel can be prevented from being damaged.
