Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to the improvement of a display terminal device.
Especially while waiting for a response from the host computer.
It relates to means for preventing the risk of incorrect input or power being cut off.

[Conventional technology]

When using a display terminal device, if the response is poor, it may take several tens of minutes before a response is returned.

In such a case, the user of the terminal device may leave the terminal device. During this time, there is a risk that another user who does not know that the user is waiting for a response may perform an input operation or the power may be turned off. If such a situation occurs, the operation of the system will be adversely affected. Therefore, the keyboard is locked using software to prevent the above-mentioned erroneous operations while waiting for a response. Therefore, other users have to wait impatiently until the corresponding terminal device becomes available, wasting their time and reducing the efficiency of using the terminal device.

[Problem that the invention attempts to solve]

This problem arises because it is not possible to see at a glance that the display terminal is waiting for a response, and the power supply is not physically locked.

SUMMARY OF THE INVENTION An object of the present invention is to provide a display terminal device that can be used smoothly to increase usage efficiency and prevent misuse.

[Means for solving problems]

The present invention provides a terminal device that is equipped with at least a keyboard, a display device, and a power source, and that is connected to a host computer via a communication line and performs online processing. a mode specifying means for specifying whether or not to respond; and if a response waiting mode is specified by the mode specifying means, setting the operation mode of the terminal device to a response waiting mode;
mode selection means for displaying a message indicating that the response wait mode is on the display device; and while the response wait mode is set by the mode selection means, input from the keyboard is prohibited and the power supply is locked. The present invention is characterized in that it is provided with a locking means for performing the locking operation.

[Effect]

If the operator leaves the display terminal while waiting for a response, which takes a long time, the operator can operate the response waiting mode specifying means to set the response waiting mode, thereby setting the display device to a predetermined setting. A message is displayed, input from the keyboard is prohibited, and the power is locked.
Therefore, other users can see at a glance that this display terminal device is waiting for a response, and even if they make a mistake, their input will not be accepted, and there is no risk of the power being accidentally turned off. .

〔Example〕

1 and 2 are a perspective view showing an embodiment of the present invention and a block diagram showing the main parts of the structure, respectively, in which 1 is a display device, 2 is a keyboard, and 3 is a device for displaying messages in this embodiment. An auxiliary display device attached to, for example, a liquid crystal display, 4 a mode designation switch, 5 a mode selection circuit, and 6 a lock mechanism such as a power switch. Note that 7 is a control unit of the terminal device, and 8 is a printing device.

During normal operation, the mode designation switch 4 is kept on the normal operation mode A side. In this case, the normal operation mode is set by the mode selection circuit 5, and the input from the keyboard 2 is read by the control section 7 via the mode selection circuit 5, and processing according to the input is performed.

If a long response waiting state occurs for some reason and the operator leaves the terminal device, the mode designation switch 4 is switched to the response waiting mode B side. In this way, the response waiting mode is set by the mode selection circuit 5, a predetermined message indicating that a response is currently being waited for is displayed on the liquid crystal display device 3, and the locking mechanism 6 is further activated so that the response from the keyboard 2 is not activated. All inputs are prohibited, and the power switch (not shown) is currently locked.

The message displayed on the liquid crystal display device 3 is as follows:
For example, “Sorry Occupied By Kosaka 30Min
Any content that indicates that a response is currently being waited for, such as "At 10:00", is sufficient.

Input from the keyboard 2 may be prohibited by blocking the signal from the keyboard 2 by the mode selection circuit 5 so that it does not go to the control unit 7, or by sending the signal to the liquid crystal display device 3. . In short, all inputs on the keyboard 2 may be ignored by the control unit 7.

The lock mechanism 6 operates in response to a signal from the mode selection circuit 5, and even if it is mechanically fixed so that the power switch cannot be moved, it also prevents the power switch from being pressed. Alternatively, it may be something that covers the power switch. Furthermore, one switch is provided in parallel with the normal power switch, and this is linked with the mode setting switch 4, so that the mode specifying switch 4
By setting the above-mentioned parallel switch to 'ON' when the switch is switched to the response waiting mode side B, even if the normal power switch is turned off, the above-mentioned parallel switch will remain active even if the normal power switch is turned off. It is also possible to supply power through the power supply.

In this embodiment, even if the operator is away from the terminal device while waiting for a response, by switching to the response waiting mode, other operators can see at a glance that the operator is currently waiting for a response. Furthermore, even if the keyboard is operated by mistake, no input will be accepted, so there is no risk of an erroneous operation, and the power switch is also locked, preventing erroneous disconnection.

[Effect of idea]

As explained above, according to the present invention, it becomes clear that the display terminal device is in a state of waiting for a response, and the risk of erroneous operation or erroneous power cut-off during that time is prevented.
