Description

[Detailed Description of the Invention] The present invention relates to a room indicator that is installed at the front desk of a hotel and used to display the status of a guest room.

The room indicator shows the status of each room, i.e. checked in,
It is composed of a part for displaying checked out cleaning in progress and cleaning completion, and a part for inputting completion of cleaning, and the present invention particularly relates to the part for inputting completion of cleaning.

Conventional room indicator input methods for indicating the completion of cleaning can be roughly divided into a block method and an individual method.

For example, the block method provides a cleaning completion switch for each floor or each area, which has the advantage of reducing the number of cleaning completion switches (reducing input effort), but cleaning is completed for that floor or the entire area. 1 cannot be entered, so there is a drawback that even if there is a room where you can check in, you cannot check in to that room with Freon).

Although the individual method has the advantage of being able to check the status of each room, it requires a lot of time and effort to enter the information because it requires pressing the cleaning completion switch for all rooms.

In view of the above, the present invention provides a device that is characterized by being an individual system, but also capable of simple input, which is an advantage of the flock system.

Fig. 1 is a perspective view showing an example of the room indicator of the present invention, and Fig. 2 is an enlarged front view of a part thereof, with guest room number 1.
and check-in, checked-out, cleaning in progress,
A display 2 for indicating that cleaning is complete and a cleaning completion switch 3 that is operated when cleaning is complete are provided corresponding to each guest room.

This room indicator is installed at least at the front desk of the hotel, but if it is installed at the maid station,
The maid can operate the switch herself when the cleaning is completed, and can immediately go to clean by checking out the checkout display on the display 2.

FIG. 3 is a block diagram showing the internal configuration of the indicator of the present invention, and 5 is a front machine installed at the front desk of a hotel for the front desk staff to perform check-in, check-out, and other various front desk operations. The cable 6 is connected to the room indicator according to the present invention.

7 and 8 are plate conversion circuits that convert the serial check-in and check-out signals obtained from the front machine 5 via the cable 6 into parallel signals of the same number as the number of guest rooms; 9 is the conversion circuit 7; Check-in obtained from 8,
This is a memory circuit that stores the status of the guest room in response to a check-out signal, and the stored contents are displayed on the display 2.

Reference numeral 10 denotes a parallel-to-serial conversion circuit that converts the parallel signal from the cleaning completion switch 3 of the room indicator into a serial signal, and its serial output is transmitted to the front machine 5 via the cable 6, and the NOR gate 11 and the delay type flip-flop 13 forming the state storage circuit 12.

The output of this NOR gate 11 is applied to the enable terminal E of the decoder 14.

Furthermore, since the state storage circuit 12 has a binary connection configuration with the flip 70 tube 13 and another delay type flip-flop 15, the state is inverted every time a signal is obtained from the parallel-to-serial conversion circuit 10. Remember.

The outputs of these two 7-lip-flops 13 and 15 are applied to the NOR gate 11 through the gate 16, and these flip-flops 13 and 15 and the gate 16
The signal generating means is configured (・ru.

Reference numeral 17 denotes a timing generation circuit that generates a timing signal, which outputs conversion and address timing for the above-mentioned tray, parallel-to-serial conversion circuits 7, 8, and 10 and decoder 14, and outputs address timing. This is for supplying a periodic reset signal to the 7 lip-flops 13 and 15.

FIG. 4 shows an example of a specific configuration of the storage circuit 9 and the display device 2, and only the portion (1) of the guest room is shown.

The memory circuit 9 includes, for example, a pair of R87 lip-flops 20.
The display 2 consists of a pair of LEDs 22 and 23 that emit light in different colors, for example red and green.

When the checkout is completed, the front machine is operated and the checkout signal CO is obtained from the tray conversion circuit 8, and both flip-flops 20 and 21 are in the reset state.

Therefore, neither of the LEDs 22 and 23 of the display 2 lights up.

When the maid confirms that this indicator 2 is not lit, she goes to clean that guest room, completes the cleaning, and operates the cleaning completion switch 2 corresponding to that guest room.A cleaning completion signal CL is obtained and the flip-flop 21 is set, the green LED 23 lights up, informing the front desk staff that cleaning has been completed and that they can check in.

On the other hand, if check-in is performed in this state, the check-in signal CI is obtained, so the flip-flop 20 is set and the red LED 22 is also lit, indicating to the front desk staff etc. that the guest room is in use. Notify.

This FIG. 4 shows a pair of R-S flips 7 as a memory circuit 9.
Although the explanation was made using a 0-tube, in reality it is made of a semiconductor.
AM will probably be used.

Returning to FIG. 3, if one cleaning completion switch 3 is operated, the parallel-to-serial conversion circuit 10 outputs a signal as shown in FIG. 5A.
One serial signal is obtained per frame.

This signal is applied to the enable terminal of the decoder 14 via the NOR gate 11, and the decoder 14 decodes the timing at which this signal A is obtained, issues a cleaning completion signal CL for the guest room associated with that timing, and stores it. The signal is output to the circuit 9, and the green LED 23 corresponding to the cabin is turned on as explained in FIG.

On the other hand, periodic reset pulses shown in FIGS. 5B and 5C are applied from the timing generation circuit 17 to each of the seven lip-flops 13.15 of the state storage circuit 12, and they are normally in a reset state.

When the parallel-to-serial conversion circuit 10 obtains one signal A, the flip-flop 13 is inverted and its output Q is obtained, but the other flip-flop 15 is in the reset state, so the gate 16 is not opened. , the flip 70 knob 13 is returned to the reset state by the reset signal in the next frame.

Usually, maids clean guest rooms one by one after the maid has checked out, but often they clean one floor or one block at a time.

In such a case, it is sufficient to operate the cleaning operator switch 3 corresponding to each guest room on one floor or one block, but if there are many guest rooms, it is troublesome to perform this operation multiple times.

In such a case, instead of operating all the switches 3 that correspond to those guest rooms, you only need to operate the two switches 3 that correspond to both ends of the consecutive guest rooms, and the guest rooms located between them will be The corresponding green LED lights up.

That is, when the two cleaning completion switches 3, 3 are operated, a signal A having a timing corresponding to each switch 3, 3 is obtained as in the previous case, and this is applied to the state storage circuit 12.

In this case, unlike the previous case, the second pulse arrives before the flip-flop 13 is reset, so the flip-flop 15 is also inverted and its output Q' is also obtained, and the output Q of the flip-flop 13 and Therefore, gate 16 opens,
When the timing signal A of the next frame arrives and the flip-flop 13 is inverted, an enable signal is supplied to the decoder 14.

As a result, all of the corresponding green LEDs 23 of the guest rooms corresponding to the period T during which the gate 16 is open are lit, thereby informing the front desk staff that the cleaning of those guest rooms has been completed.

As is clear from the above explanation, the room indicator of the present invention includes a parallel-to-serial converter that is connected to a cleaning completion switch and outputs a serial signal at a timing corresponding to the operated cleaning completion switch, and a parallel-to-serial converter that outputs a serial signal at a timing corresponding to the operated cleaning completion switch. When a signal is generated at two different timings, a signal generating means generates a serial signal at all timings between these two timings, and the signal is output from the parallel-to-serial converter and the signal generating means. It consists of a display means that displays the state of the guest room corresponding to the timing of the signal, such as a cleaning completion state, so that when cleaning of multiple consecutive guest rooms is completed, the switch corresponding to both ends of the guest rooms is operated. By simply doing this, all of the guest rooms located between them can be cleaned, which is extremely useful as it frees you from the hassle of switch operations and speeds up the process.
