Abstract
To make a malfunction hard to generate, and to simplify a circuit to perform a sound recording and a reproduction, by sound recording a tone burst wave signal on a business tape as a control signal, and controlling the business tape by the control signal. On completing the transmission of a business message from a caller, a sound detecting circuit 28 detects a nonaudio state, and a timer 27 is started up, and an output signal is outputted to a tone burst wave signal generation circuit 21 for a regulated time. Thereby, the tone burst wave signal is sound-recorded on the terminal part of the business message recorded on a business tape 9 with a business recording and reproducing head 11. By reproducing the business message recorded on the business tape 9 at a high speed, a marker signal generated by the business signal and the tone burst wave signal, is vocalized by a speaker 34 through the business recording and reproducing head. Simultaneously, it passes through the second waveform arranging circuit 35, and is detected with the second detection circuit 37. A queue review mechanism is stopped by the detecting output of the circuit, and the reproduction of the business message can be performed exactly from the head of the message.
Description
This invention relates to the feed mechanism of cylinder-shaped sewing machine, is particularly useful for having the differential amount guiding mechanism of the cylinder-shaped sewing machine of differential feed mechanism of moving forward.
The differential feed mechanism of moving forward of Sewing machines, usually, the main feeding platform of main feeding tooth is installed and the differential feed platform of differential feed tooth is installed, be connected with the differential feed crank with main feeding crank by connecting rod respectively, and main feeding crank and differential feed crank be fixedly mounted on main shaft interlock and the feeding antero posterior axis swung on, utilize the swing of two cranks to move forward and backward.The adjustment of differential feed amount is by chimeric with the differential feed crank, and the slide block that is connected rotationally with connecting-rod head moves realization along the differential feed crank, the differential feed crank is radially extended by the feeding antero posterior axis, and the adjustment of slide position utilizes driving methods such as manual control mechanism or pulse motor to realize.About manual control mechanism, a kind of pattern is to make sliding part be entrenched in the tooth fork place of tooth fork control stick, wherein, sliding part and slide block be rotaryly be connected, tooth fork control stick is rotating connection the (seeing the spy public clear 47-17019 number) with framework, another kind of pattern is to utilize connecting rod to connect control stick and sliding part, wherein, control stick is rotating connection the (seeing special public clear 56-15916 number) with framework.To the former mechanism, represented as 4A figure, owing to the arc track of the slide block 2 that 1 swing of differential feed crank is drawn uses the straight line near this track to be similar to, that is, slide block 2 does reciprocating linear motion in tooth fork 3 when differential feeding crank 1 is swung, owing to departed from desirable arc track, microvibration takes place along differential feed crank 1 in slide block 2, and therefore, both produce abrasion, cause the vibration of Sewing machines, the cloth feeding effect of differential feed tooth is degenerated.Such problem, though a kind of pattern in back makes moderate progress than preceding a kind of pattern, but do not eliminate fully, promptly, represented as 4B figure, slide block 6 is not that the oscillation center C with differential feed crank 7 is the center desirable arc track that draws, but is the center arc track that draws with the b that is rotatably connected of control stick 8 and connecting rod 9, has deviation between the two.
About manual control mechanism, except that above-mentioned pattern, as special public clear 58-1955 number disclosed, though considered that the track of the actual motion that makes slide block is consistent with desirable arc track, but in this mechanism, the pattern represented with 4A figure is the same, owing to come the desirable arc track of approximate representation with straight line, still has the bigger shortcoming of deviation ratio between two tracks.
At above-mentioned problem, for the deviation of the actual motion track that reduces slide block and desirable track as far as possible, this application people proposes earlier as 4C figure represented, the arc track e of the slide block that draws
1, make track e then
