伝送線路（７）を通じて直列−並列変換器（６）に送る
。FIG. 2 shows how this transmission is performed in series. First, a sending request (4) is sent from the receiving end (2) to the sending end (1). When the sending request (4) is input, the sending end (+1) sends parallel data to one parallel-to-serial converter (5). This converter (
5) converts the parallel data into serial data and sends it to the serial-parallel converter (6) through the serial transmission line (7).
そしてこの変換器＋６１は直列データを並列データに変
換し、受信端（２）は該並列データを受は収り、処理を
行なう。This converter +61 converts serial data into parallel data, and the receiving end (2) receives and processes the parallel data.

並列の転送速度のビット数倍の速度で１ビツトを転送し
なければならず、そのため伝送線路を高速化しなければ
ならないという欠点があった。In the conventional system + tVi, since the receiving end (2) issues a sending request (4), the transmitting end (41) is configured so that the tll outputs data, so if the transmission line length becomes long, the data will be sent twice as long as the transmission line length. At the same time, the transmission speed of the serial transmission line (7) also increases as the transmission speed of the serial transmission line (7) slows down and the time it takes for the receiving end (2) to issue a sending request (4) and receive the data becomes longer. One bit has to be transferred at a speed that is twice the transfer speed as the number of bits, and therefore the transmission line has to be made faster.

送装置ａを提供することを目的としでいる。This invention was made in order to eliminate all the drawbacks of the conventional ones as described above.One register is provided between the receiving end and the serial-to-parallel converter, and the receiving end requests transmission of this register. and receive the register, and the register is
By using the information that this is empty as a transmission request signal so that the transmitting end makes a transmission request, the time it takes for the receiving end to receive data after issuing a transmission request can be shortened, and the transmission line can be further shortened. It is an object of the present invention to provide a signal transmission device a that does not require high speed.

求する信号である。In FIG. 3, the same reference numerals as in FIG. 2 indicate the same parts. (8) is a register provided between the serial-to-parallel converter (6) and the receiving end (2), when the register (+91 l''ii register) is empty, from the register (8) to the transmitting end (1 )
This is a sending request signal output to. Above register +81
It has the function of temporarily storing the data output from the l'i converter (6) and transmitting the data from the sending request (4) from the receiving end (2), and the register (8)
The sending request value 8 (9) output from the register (8) is a signal requesting sending of data to the sending end (11) when the register (8) becomes empty.

６）で並列化されてレジスタ（８）にだくわえられる。When the receiving end (2) sends a sending request (4) to the register (8) to request data transmission, the register (8) sends the stored data to the receiving end (2). Then, since the register (8) becomes empty, the register (8) outputs the transmission request signal (9). When this transmission request signal (9) is input to the transmitting end (1), the transmitting end sends the parallel data to the parallel-to-serial converter t511. The serialized data here is transmitted through a series transmission line (
7) and enters the series-to-parallel converter (6) via the converter (
The data are parallelized in step 6) and stored in register (8).

送ｏｒ能であるという効果がある。As described above, according to the present invention, when a parallel transmission line is replaced with a serial transmission line, a register is provided between the receiving end and the serial-parallel converter, the receiving end interfaces with this, and the transmitting The transmission request to the end uses the signal when the register becomes empty (Since the configuration has been configured, the data transmission request from the receiving end is responded to once, eliminating the influence of the line length, and the signal is sent to the receiving end. It is possible to receive the next data while processing data, and there is an effect that serial transfer is possible at a slower speed than the bit transfer speed which is twice the number of pits.
