_n-1 is 16 lines x 8 characters = 128 lines, and 7 dot lines are provided between the characters as a space where characters do not connect 128
+ 7 = 135. The electrodes Y _{0 to} Y ₁₅ and the electrodes X _{0 to} X _n-1 are provided so as to intersect with each other, and characters are displayed by selectively emitting light at each of these intersections. In FIG. 4, a black dot (•) is an issue display dot.

An example of the internal configuration of the control unit 6 of each display device 2 is shown in FIG. In this example, it consists of a microcomputer,
In addition to a central processing unit that sequentially reads and decodes a program, a so-called CPU 13, a readable / writable memory RAM 14 used for work and data editing used in various arithmetic processes of the CPU 13, a memory ROM 15 storing a control program,
Input / output port for interfacing with dot type display 7
17 is connected to bus 19. Further, a display code such as a station name or an advertisement display is input to the input port 16 through the terminal 800, and a display code such as caution information is input to the input port 16 through the terminal 801, and the input port 16 is connected to the bus 19. Further, the input / output port 18 is for interface with the display data storage unit 5, and is similarly connected to the bus 19.

FIG. 6 shows an example of the internal configuration of the control unit 10 of the command device 1. This example also consists of a microcomputer, CPU2
0, ROM21, RAM22, and input / output ports 23, 24, 25 are connected by a bus 26. The display code storage unit 9 is connected to the bus 26 through the input / output port 25. In addition, terminals 400, 401 …… 4 ×
× is a terminal for inputting designation of a route to be operated, display switching signal such as station name or advertisement display, getting-off signal signal, door opening / closing signal, direction signal, etc., and each signal is input by driving operation or operation operation. Take bus 26 through port 24.

The route set to explain the display example is shown in FIG.
It is a service route 01 starting from Tokyo and ending at Shizuoka. A display example is shown in FIG. Indicators 2 ₁ and 2 ₂ are for displaying station names,
This is an example in which the next stop is always displayed, but "Thank you for boarding" is displayed while the door is open. Display 2 and ₃ are "next stop" and "on the right" according to the operation. This is the case when the main purpose is cautionary information such as "Turn".

The display data storage unit 5, as shown in FIG. 9, is a pattern memory RO that stores the dot pattern of each character as data.
It is composed of 510 of M1 and 520 of character code memory ROM2 that stores a display character corresponding to the display code as a code. The pattern memory 510 can read the pattern data of the character by the character code as shown in FIG. As shown in FIG. 11, the character code memory 520 corresponds to the display code 000 for displaying Tokyo station, for example, "East" character code 11, "Kyo" character code 04, "Station".
The respective character codes 15 of are stored. FIG. 11A is a character code memory for displaying the station names of the displays 2 ₁ and 2 ₂ , and FIG. 11B is a character code memory for mainly displaying the cautions and advertisements. Areas 521 and 523 are areas for storing the normal display, that is, the content displayed by the display code from the commander 1, and areas 522 and 524 are the areas for storing the content displayed by the processing of the interrupt code generated by a special state. . However, in this embodiment, the normal display and the interrupt display are formed by separating the signal lines, but if the display of each display is the same, the signal lines are not separated and only one is displayed. Can communicate.

An example of the display code storage unit 9 of the command device 1 is shown in FIG. In the case of a bus, when the operating route A01 is set, the display codes 001, 002 ... 005 are sequentially read by the station signal pulse. This display code is converted from the command device 1 into a signal (parallel or serial) determined by the transmission method and sent to each display device. Each display 2 reads the character code memory 520 according to the sent display code, reads the read pattern data of each character code from the pattern memory 510, and displays it on the display unit 7.

[Advantages of Device] As described above, according to this device, the configuration of each display can be made common and the cost can be reduced. Moreover, by changing the stored contents at the same address for the display data memory by the display unit, for example, as shown in FIG.
Even if 002 is supplied to the display unit, the station display unit 2 ₁ receives this display code and displays "Odawara station", but the advertising display unit 2 ₃ displays "Please use ○○ department store". It Therefore, the number of types of display codes stored in the display code storage unit 9 of the command device 1 may be small.

Further, it is not necessary to attach a destination (address) for distinguishing each display device 2 ₁ , 2 ₂ ... to the transfer display code, and it is not necessary to transfer the display code for each different display, that is, in the above example, "Odawara station" Only one display code needs to be transferred once in order to display and "Please use XX department store", and display control can be performed at high speed. Commander 1
Usually, they often perform not only display control but also various other tasks, and in that respect, it is very advantageous to be able to perform display control at high speed. Of course, the same display may be displayed on each display.

When the display device is applied to a vehicle such as a bus as shown by a dotted line in FIG. 1, the boarding / alighting survey device 31 is connected to the signal line 3 and the code (or the code indicating the station in the display code issued from the command device 1 (or All display codes) can be stored, and together with this, a signal indicating the passengers getting on and off at each stop station from the terminal 32 can be input and counted and stored correspondingly. Conventionally, each count value of passengers was stored for each station signal, but if the correspondence relationship between the station signal and the storage of the count value is deviated due to an incorrect station signal, the boarding / alighting survey cannot be used at all. However, as described above, if each count value of passengers is stored in association with the display code of each station, even if an incorrect station signal occurs, the driver corrects the difference between the station display and the reading of the display code storage unit 9. Therefore, the correct boarding / alighting survey result can always be obtained.
