It is composed of.

Next, the operation of the first embodiment will be described with reference to FIGS.
It will be described with reference to the steps up to 2. FIG. 2 shows a storage state of the storage device 10A. 3 to 7 are flow charts showing the operation of the selecting means 10C, FIG. 8 is a flow chart showing the operation of the detecting means 10D, and FIG. 9 is a flow chart showing the operation of the synthesizing means 10E. It is assumed that they operate separately depending on the specific interrupt processing.
10 shows a display example when there is no video signal, FIG. 11 shows a display example when there is a video signal, and FIG. 12 shows a display example of operation guidance information.

The storage state of the storage means 10A will be described assuming that both the reservation message and the operation guide information can store up to 10 pieces. In FIG. 2, n is the number of reservation messages currently registered, S (1) to S (10) are display start reservation times for messages 1 to 10, and E (1) to
E (10) is the display end reservation time for messages 1 to 10, and M1 (1,1) to M1 (10,4) are numbers 1 to 1.
This is message data No. 0.

One message is divided into units of 10 characters according to the display unit 14. These 10 characters are regarded as 1 data and are formed by a combination of 4 data. M
The first message is formed by 1 (1,1) to M1 (1,4). Here, the first subscript in the parentheses of M1 represents the message number, and the second subscript represents the data number in the message number. Since the number of reservation messages is "9", 1
Data area S (10), E (10) of message 0
And M (10,1) to M (10,4) are blank.

Further, M2 (1,1) to M2 (10,4)
Is message data of the operation guidance information of Nos. 1 to 10. The meaning of the subscript in parentheses of M2 is the same as that of M1. Since the operation guidance information is displayed according to a command from the elevator control device 12, there is no reservation data.

Further, t is the current time read from the clock 10B, a is a flag for deciding whether or not to cut the video signal when the synthesizing means 10E synthesizes the message and the video (when the video signal is not cut, “1”, “0” when cutting, v is a flag indicating whether or not the detecting unit 10D has detected a video signal (“1” when a video signal is detected, “0” when not detecting). , P, i, and j are variables, and k is a message number that is commanded to be displayed by the elevator control device 12 (“0” when there is no display command). Note that D (1) to D (4) are message data to be combined by the combining unit 10E.

Next, the operation of the selection means 10C will be described. First, in FIG. 3, in step 21, n is substituted for the variable i to initialize the variable. Next, at step 22, it is judged whether or not there is a message display command from the elevator control device. If there is no display command (k = 0), the process proceeds to the selection program of step 23, and if there is (k ≠).
0) proceeds to the transfer program 3 in step 24. When step 23 or step 24 is completed, step 22
Return to and repeat the operation.

Details of the selection program of step 23 in FIG. 3 will be described with reference to FIG. First step 31
Substitute "1" for a so as not to cut the video signal with. Next, in step 32, the first message number is set to the variable p.
, And proceed to step 33.

In step 33, "1" is added to the variable i, and in step 34 it is determined whether the variable i is larger than n. If it is larger, proceed to step 35 and set variable i to "1".
Is substituted, and if not larger, the process proceeds to step 36 as it is. Note that steps 33 to 35 are processes for repeating the message numbers from 1 to n.

In step 36, it is determined whether the message with the number represented by the variable i is within the display period. If the current time (t) is between the display start time (S (i)) and the display end time (E (i)), the process proceeds to step 38, and if not, step 3
Proceed to 7. In step 37, the message number stored in the variable p and the message number stored in the variable i are compared. If they match, the operation of the selected program is terminated, and if they do not match, the process returns to step 33 to determine the next message. Note that step 37 is a process for dealing with all messages outside the reservation period, and prevents infinite repetition.

In step 38, it is determined whether a video signal has been detected. When it is detected (v = 1), the process proceeds to the transfer program 1 in step 39, and when it is not detected (v = 0), the process proceeds to the transfer program 2 in step 40. Step 39
Alternatively, when step 40 ends, the selection program ends.

Details of the transfer program 1 in step 39 in FIG. 4 will be described with reference to FIG. First step 5
At 1, the display storage areas D (1) to D (4) are cleared.
Next, at step 52, the message data M1 (i, 1) to M1 (i, 4) having the numbers representing the variable i are displayed in the display storage area D.
(1) to D (4). Then, in step 53, the timer is reset and the process proceeds to step 54. After waiting for a predetermined time to elapse in step 54, the transfer program 1 ends. Note that steps 53 to 54 are processes for displaying character information for a predetermined time.

Details of the transfer program 2 in step 40 in FIG. 4 will be described with reference to FIG. First step 6
At 1, the variable j is substituted with "1". Next, at step 62, the display storage areas D (1) to D (4) are cleared, and the routine proceeds to step 63. In step 63, a part of the message data M1 (i, j) of the message number represented by the variable i is transferred to the display storage area D (1). This gives D (2)
D to (4) are blank areas, and only a part of the data transferred to the area D (1), that is, the data of the number represented by the variable j is displayed.

Next, at step 64, the timer is reset and the routine proceeds to step 65. After waiting for a predetermined time in step 65, the process proceeds to step 66. Note that steps 64 to 65 are processes for displaying character information for a predetermined time.

In step 66, "1" is added to the variable j. Then, in step 67, it is determined whether or not all the messages with the numbers represented by the variable i have been displayed. If the data number represented by the variable j is larger than "4", the transfer program 2 is terminated, and if not, the process proceeds to step 62 to display the next data.

Details of the transfer program 3 in step 24 in FIG. 3 will be described with reference to FIG. First, in step 71, "0" is substituted for a so as to cut the video signal. Next, at step 72, the display storage areas D (1) to D (D)
(4) is cleared and the process proceeds to step 73. Step 7
In 3, message data M2 (k, 1) of the number represented by k
To display memory areas D (1) to D representing M2 (k, 4)
Transfer to (4). This completes the transfer program 3. In the transfer program 3, when the display command from the elevator control device 12 disappears (k = 0), the display of the operation guidance information is immediately erased, and thus the predetermined time does not wait.

Next, the operation of the detecting means 10D will be described. First, in FIG. 8, in step 81, it is determined whether the level of the video signal exceeds a predetermined value. When it exceeds, it proceeds to step 82, and when it does not exceed, it proceeds to step 83. In step 82, "1" is assigned to v to notify that the video signal is detected. In step 83, "0" is substituted for v to notify that the video signal is not detected. When step 82 or step 83 is completed, step 8
Return to 1 and repeat the operation.

Next, the operation of the synthesizing means 10E will be described. First, in FIG. 9, in step 91, it is determined whether or not the video signal is cut. When not cutting, that is, when a is “1”, the process proceeds to step 92, and when cutting is performed, that is, when a is “0”, the process proceeds to step 93.
In step 92, the video signal and the display storage area D (1)-
And D (4). In step 93, the video signal is cut and combined with the display storage areas D (1) to D (4). That is, the data in the display storage areas D (1) to D (4) are displayed as they are. Step 92 or Step 9
When step 3 is completed, the process returns to step 91 and the operation is repeated.

Since the selecting means 10C, the detecting means 10D and the synthesizing means 10E operate as described above, when there is no video signal, character information is displayed on the entire screen as shown in FIG.
When there is a video signal, character information is displayed using only the upper one line as shown in FIG. Also, the elevator control device 1
When there is a message display command from 2, the character information only is displayed on the entire screen as shown in FIG. 12, regardless of the presence or absence of a video signal.

The first embodiment of the present invention, as described above,
An object of the present invention is to prevent the character information and the video information from being overlapped and displayed on the entire display screen in the elevator display 14 which can display both the character information and the video information.
Therefore, a detecting means 10D for detecting the presence / absence of the video signal is provided, and the composition method of the character information and the video information is switched depending on the presence / absence of the video signal.

Example 2. In the first embodiment, when there is a video signal, the upper one line is used as the character information display area to switch and display the messages, but the messages may be horizontally scrolled in the display area.

Example 3. Further, in the above-described first and second embodiments, the upper one line is used as the character information display area when there is a video signal, but the lower one line may be used. Furthermore, a character information display area smaller than the screen may be set and displayed in that area.
