Abstract

PURPOSE:To easily change the contents of talkies and to attain program searching on plural lines by controlling the addresses of a storage circuit to be read out in each line at the time of sending a talkie to search each program, and after completing the writing of a new talkie, sending the new talkie from the line receiving a sending instruction. CONSTITUTION:The talkie sending equipment is constituted of an analog/digital converter(A/D) 50, try state gates(G) 80, 81, a control circuit(CONT) 70, and so on. An analog input from the external is converted into a parallel digital signal by the A/D 50 and inputted to the G 80, 81. In the case of reading out the contents of a memory circuit(MEM) 11, the CONT 70 controls a selection circuit(SEL) 33 when the CONT 70 receives a talkie sending instruction, and the output of the MEM 21 is set up as the address of the MEM 11. Addresses at the time of reading out the MEM 21 are controlled by the CONT 70, the addresses are determined in respective lines and the read output of the MEM 11 is converted into a serial signal and outputted. Thus, the contents of the talkies can easily be changed and an optional program can be searched on plural lines.

It comprises a 5EL33 that selects an address from CNT41 or an address from MEM2]-, and a control circuit (hereinafter referred to as C0NT) 70 that controls the entire embodiment.

Next, the operation of this embodiment will be explained.

For analog input from the outside, input the talkie write instruction to C0NT.
70 is converted into a parallel digital signal by the A/D 50 during reception and input to C80,8]. At this time, ME
If you are sending out a talkie using MII, C0
NT70 opens G80, a digital signal is input to MEMlo, then C0NT70 opens S E L, 32
and selects the output of CNT40 as the address input of MEMIO. The input clock of CNT40 is 1.25
A μs clock is supplied from C0NT70. Then 125. Data can be written to an address that is incremented by 1 for each us. This behavior is
If O is used to send out a talkie, the above operation is performed on the MEMll side.

Next, to read MEMII,
When 0NT70- receives, C0NT70 sends S E L
33 so that the output of MEM21 becomes the address of MEMll. The output of MEM21 is ADD91
is inputted to ``1'', and is written to the same address of MEM21 through 5EL31. MEM21
The address when reading is controlled by C0NT70,
An address is determined for each line. At this time, the read output of MEMII passes through SEL 34,
The P/S 60 converts it into a serial signal and outputs it.

1--When the key transmission is completed, C0NT70 becomes 5EL3.
1 and writes °"0 as data in the MEM 21, and sends out the talkie from the beginning.Also, when the CON T 70 receives an instruction to stop the l/- keys from the outside, the MEM21 E M21's corresponding address is °0''
Keep it.

If the capacity of the MEM2F is prepared in steps 1-7 for the number of lines to be sent out, the two-leg operation can be performed for each line. Furthermore, after the new talkie writing is completed, a new one is sent from the line that received the talkie transmission instruction under the control of C0NT70.
--key can be sent.

〔Effect of the invention〕

As explained above, the present invention converts an external analog signal into a digital signal, has two write memory circuits, stores the currently transmitted talkie, and writes the digital signal in the non-memory circuit. When transmitting a talkie, the address of the memory circuit to be read out is controlled for each line, and a "C cue 7" is performed, and after the new talkie has been written, a new 1-key can be sent from the line that received the talkie transmission instruction. By doing so, it is possible to supply a plurality of lines with talkies that are easy to change and can be cued.
