DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a centralized transmitter, a fixed display receiver, and a wireless call system using the same.

[0002]

2. Description of the Related Art Conventionally, in restaurants and the like,
When a button on the transmitter attached to each table or room is operated, a wireless signal is transmitted as a call signal, the receiver receives it, displays the table number, etc., so that waitresses and waiters can respond quickly. The wireless call system has been adopted.

FIG. 7 shows a configuration of a conventional wireless call system. The illustrated system is a weak system using a weak radio wave whose practical range of the radio wave is about 15 m, and each button of the centralized transmitter 110 and the desktop transmitter 1
20 and each of the display windows of the display unit 100 are one-to-one.
(Or multiple to one), and the numbers are fixedly displayed in each display window.

In this case, two display units 100 (# 1 and # 2) each having eight display windows are provided, and a total of 16 display units are provided.
Can be displayed on the display window. A notification unit 101 is connected to the display unit 100 to notify that a call has been made by a sound such as “ping-pong”. In this system, the display units 100 (# 1, # 2) are used as transmitters in addition to the desktop transmitter 120.
A centralized transmitter 110 (# 1, # 2) is provided for each. In the centralized transmitter 110, when a button corresponding to each of the display windows of the display unit 100 is operated, a control signal specifying the window is transmitted, and the corresponding display window can be turned on or off.

[0005] That is, when calling from the centralized transmitter 110, when any button of the centralized transmitter 110 is operated, the antenna 102 receives the lighting control signal transmitted from the centralized transmitter 110. Each display unit 100
The ID code corresponding to each button of the centralized transmitter 110 included in the call signal is determined, the blinking display of the display window corresponding to the ID code is started, and the notification unit 101 outputs a notification sound. If a blinking display is made when a call is made, the caller can be identified at a glance even if other display windows are lit. This blinking display switches to a lighting display after a predetermined time has elapsed.

In the figure, button 1 of centralized transmitter 110 (# 1)
The number "5" is displayed on the display window corresponding to the ID code of 11a, and the number "12" is displayed on the display window corresponding to the ID code of the button 111b of the centralized transmitter 110 (# 2).
Then, when the response to the calling source is completed, as shown in FIG. 8, the mode switch SW100 on the back side of the centralized transmitter 110 is switched from on to off, and then the button is operated. A light-off control signal including an ID code is transmitted, and the display is turned off (erased). The display on the display window can be automatically deleted after a predetermined time has elapsed. In FIG. 8, reference numeral 112 denotes a mounting bracket for mounting the centralized transmitter 110 on a wall or the like.

FIG. 9 is a time chart showing the above operation. When the button of the centralized transmitter 110 is operated while the mode changeover switch SW100 is on the “lighting” side, the display unit 100 corresponding to the ID code of the button is operated.
When the button of the centralized transmitter 110 is operated in a state where the display window is turned on and the mode changeover switch SW100 is set to the "light-out" side, the display window of the display unit 100 corresponding to the ID code of the button is turned off I do.

If the mode switch SW100 is turned off when the button of the centralized transmitter 110 is operated while the display window of the display unit 100 is turned off, the display window is kept turned off. I do. Conversely, with the display window of the display unit 100 turned on, the centralized transmitter 1 whose mode changeover switch SW100 is set to the “lit” side
When the button 10 is operated, the display window is kept lit.

Next, FIG. 10 shows another configuration of a conventional wireless call system. Here, a low-power system in which the practical reach of radio waves is about 40 m is shown.
The display receiver 200 has eight display windows 201. When a lighting control signal is transmitted by a button operation of the centralized transmitter 210, the display receiver 200 receives the signal and determines an ID code included in the lighting control signal. Then, the number corresponding to the ID code is displayed from the upper left display window 201 in the order in which the call was made, and a notification sound such as “ping-pong” is output. That is, in this system, two of the display receivers are used.
The 00 display window 201 is composed of a 7-segment display or the like, and is configured to variably display numbers.

In the centralized transmitter 210, a number button 211,
A lighting control signal or a light-off control signal is transmitted by a combination of operations of the call button 212 or the delete button 213. For example, to display the number “25” on the display window 201 of the display receiver 200, “2” and “5”
Is operated, then the call button 212 is operated. Then, a lighting control signal including an ID code for displaying the number “25” is transmitted.

In the figure, the number "2" called first,
A state in which the next called number “12” and the last called number “25” are displayed on the display window 201 in this order is shown. In addition, a dot "." Is attached to the display so that the first call can be easily understood. 7 and FIG.
The wireless call system shown in (1) is used for a variety of purposes, such as a call from a customer in a restaurant or the like, a notification of a change in cash from a cash register, a notification of a lack of parts in a production line of a factory, and the like.

[0012]

However, the wireless call system shown in FIG. 7 has an advantage that the display is fixed on the display unit 100 so that the visibility is excellent, and the display control is simple, so that the cost can be reduced. However, in order to switch the display window on and off by operating the centralized transmitter 110, before operating the button, the mode control switch SW100 must be operated to set the mode according to the control signal to be transmitted. Operation was troublesome. In particular, when it is attached to a wall or the like by the attachment fitting 112, it cannot be removed one by one.

Therefore, the actual centralized transmitter 110 is used exclusively for lighting or for turning off the light. For example, in a restaurant, a display window lit by operating the tabletop transmitter 120 at the guest seat is provided in a kitchen or the like. The centralized transmitter 110 dedicated to turning off the light was operated to delete the light. Therefore, in order to use the display unit 100 for an exit display in which each display window to which a name plate or the like is attached alternately turns on and off, it is necessary to use one display unit 100 in terms of operability. Two centralized transmitters 110 were to be provided.

The display unit 100 can be turned off if a predetermined time has elapsed since the display window was turned on, but it cannot be used for the display of going out. On the other hand, FIG.
In the wireless call system shown in FIG.
In the case of 00, in order to facilitate variable display, the display window 201 is formed of a 7-segment display, which can display only numerals, and is not suitable for in-and-out display. To turn on or off the display window 201 with one centralized transmitter 210, the number button 211 and the call button 212 or the erase button 213
2 or more operations were required.

The present invention has been made in view of such circumstances, and a centralized transmitter, a fixed display receiver, and a centralized transmitter, which can turn on and off each display window alternately with a simple operation. The purpose of the present invention is to provide a wireless call system using the Internet.

If the light is turned off, "departure" can be indicated. Such a system can be configured only by providing one centralized transmitter 3 for one display receiver 1 or additional display 2.

In this case, the mode changeover switch may have a configuration in which the lighting-off alternate mode of the mode changeover switch SW shown in FIG. 3 is replaced with a sequential changeover mode. Accordingly, the mode switch SW can be switched to a one-touch lighting mode and a one-touch extinguishing mode in addition to the sequential switching mode. When switching to the one-touch lighting mode, the centralized transmitter 3 transmits a lighting control signal every time a button is operated. When switching to the one-touch light-off mode, the centralized transmitter 3 transmits a light-off control signal every time a button is operated.

It is preferable that all of the three switchable modes are provided. However, two modes, a sequential switching mode and a one-touch lighting mode, or two sequential switching modes and a one-touch extinguishing mode are provided. You may do so. As described above, in the wireless call system of the present invention, the centralized transmitter 3 capable of transmitting three or more different control signals and the fixed display provided with a plurality of lamps having different lighting colors in each display window 1A (21). Receiver 1 (further,
It can be configured in combination with the additional display 2).

Although the case where the centralized transmitter 3 changes the control signal to be transmitted each time the button is operated has been described above, this may be performed on the fixed display receiver 1 side. . That is, the display may be changed each time a control signal is received for each of the display windows 1A and 21. With such a configuration, for example, a centralized transmitter 3 is installed in a restaurant kitchen or the like, a call from a customer using a tabletop transmitter is lit in red, a call from the kitchen to a completed dish is lit in green, and a dish is lit. When carrying, display control such as turning off the light by another transmitter becomes possible. Also, in a factory or the like, when a shortage of parts is notified from a production line using a table-top transmitter, the lamp flashes. On the other hand, the central transmitter 3 on the warehouse side turns on when parts are ready, and turns off when the parts are received. You can also.

[0048]

As can be understood from the above description, the centralized transmitter according to the first aspect of the present invention has a lighting control signal and a lighting control signal each time the same button is operated in the lighting-light switching mode. Since the signal and the signal are transmitted alternately, the centralized transmitter can be used for an exit display system for alternately displaying the exit / exit by one-touch operation. With one centralized transmitter, two states of the display window can be controlled.
The system configuration becomes compact, and construction can be reduced.

In the sequential switching mode, in the sequential switching mode, a plurality of control signals are cyclically transmitted each time the same button is operated. It can be used for an access display system that switches and displays the information in order. Since one centralized transmitter can sequentially control three or more states of the display window, the system configuration can be made compact and the construction can be reduced.

In the centralized transmitter according to the third aspect, if a one-touch lighting mode is set in addition to the lighting-off alternate mode or the sequential switching mode, a lighting control signal is transmitted each time a button is operated. In the one-touch extinguishing mode, the extinguishing control signal is transmitted each time the button is operated, so that the centralized transmitter can be used only for lighting or extinguishing as in the related art.

In the fixed display receiver according to the fifth aspect, every time three or more different control signals are received for the same display window, the lighting color of the display window is changed and turned off in a cyclic manner. This display receiver can be used in an exit display system or the like for displaying an order by sequentially switching between exit and destination.
Further, since the lighting color changes in order, the display state can be easily identified.

In the wireless call system according to the sixth aspect, since the centralized transmitter according to any one of the first to fourth aspects and the conventional fixed display receiver are combined, this system is integrated with the centralized transmitter. The present invention can be applied to, for example, an entry / exit display system in which the entry / exit is alternately switched and displayed by a one-touch operation of a transmitter. Since the two states of the display window can be controlled with each button of one centralized transmitter, the system configuration is compact and the construction can be reduced.

In the wireless call system according to the seventh aspect, since the centralized transmitter according to the second aspect and the fixed display receiver according to the fifth aspect are configured in combination, this system is provided with a centralized transmitter. The present invention can be applied to a leaving / displaying system and the like, in which a one-touch operation is used to cyclically switch between a leaving and a destination and display the destination. Since three or more states of the display window can be controlled by each button of one centralized transmitter, the system configuration can be made compact and the construction can be reduced.
