Next, the second rotating mechanism M12 is rotated at a speed twice the first rotating mechanism M11, and the chuck 13 is horizontally transferred from the point B to a point C. Therefore the horizontal displacement from the point B to the point C can be performed by a complete linear motion.

Filed: 1981-01-21
Abstract: PURPOSE:To facilitate the start of junction recording, by stopping running of a tape when the absence of the RF signal in a reproduced video signal or the synchronizing signal in a reproduced luminance signal is detected. CONSTITUTION:The reproduced video signal taken out from a video head 1 is amplified as an RF signal by a preamplifying circuit 2. This RF signal is separated by a separating circuit 3 and is sent to a regenerative chrominance signal amplifying system 11 and a regenerative luminance signal amplifying system 12. The RF signal from the circuit 2 is applied to an RF signal detecting circuit 6. The demodulation signal of the luminance signal demodulated by a demodulating circuit 4 has the synchronizing signal separated through a synchronizing signal separating circuit 7, and the synchronizing signal is applied to a synchronizing signal detecting circuit 8. A deciding circuit 9 stops running of the tape when the absence of the signal of the circuit 6 or the signal of the circuit 8 is detected. Consequently, accurate junction recording is performed from a part where no video is recorded.

Title: Automatic playing device
Inventor: KAWAGUCHI YUKIHIRO
IPC: G10H1/00
Filed: 1988-01-14
Abstract: PURPOSE:To attain a tempo rate setting with one time of operation by automatically transmitting a sign with a sign generating means, executing prescribed operation when a desired time is passed after this generating timing and setting the new tempo rate. CONSTITUTION:For example, when a tap tempo setting switch 6g is depressed at a time t1, the contents of a register TMCTR at this time point are written to a register TIME and further, a tempo value to correspond to this value is written to a register TMP. As this result, a green lamp G, which is turned on at a time t2, is turned on at a time t'2 according to a new tempo. Thus, the next tempo is set according to a time from a measure line timing, with which a red lamp R is turned on, to the depressing of the tap tempo setting switch 6g. Thus, even during a playing, matching a human sense of tempo, setting can be executed with a single operation.

Abstract: PURPOSE:To accurately adjust tension of a tape and to reduce deterioration of the tape due to friction at the time of fast forwarding and rewinding by setting an auxiliary guide into a position of noncontact with the tape at the time of fast forwarding and rewinding. CONSTITUTION:The tape being sent from a supply reel in a cassette (c) is supplied via various guides and a drum (b) to a take-up reel. That is, the tape being sent from the supply reel is supplied to the drum (b) via an S-guide post (k), the auxiliary guide (j), a tension detecting guide (i), an S-vertical roller (h) and an S-slant post (n). The guide (i) out of them is fitted to the tip of a tension lever (d). Consequently, when the lever (d) is moved, the tension detecting guide (i) is also moved. The guide (j) is positioned inside from a straight line connecting a contact point between the roller (h) and the tape with a contact point between the post (k) and the tape. By this method, since the tape is not brought into contact with the tape at the time of fast forward reproducing, deterioration of the tape is reduced.
