Title: Magnetic recording/reproduction head
Inventor: SHIMIZU TOSHIO
IPC: G11B5/187
Filed: 1987-11-13
Abstract: PURPOSE:To prevent complete adherence due to magnetic repulsion force, to improve the durability of a head and a tape and to considerably reduce external noise by covering a part of the surface of the head by means of a superconductive material and providing a tape supporting part. CONSTITUTION:A part of the surface of the magnetic head 1 is covered by the superconductive material 2, and the tape supporting part 3 supporting the magnetic tape 5 is provided. With the Meissner effect of the superconducting material in such constitution, repulsion force occurs lest the magnetic flux of the magnetized tape enters the superconducting material 2 of the head 1. By using it, the tape 5 is held in a non-contacted state with the head surface, and the friction and dirt of the tape can be prevented, whereby durability can be improved. With magnetic shielding due to the minus effect of the superconducting material 2, a magnetic path where a magnetic flux passes on the surface of the head is restricted and the unnecessary magnetic flux is shield, whereby external noise can considerably be reduced.

Abstract: PURPOSE:To copy without giving an influence on a busy communication line even when a communication equipment and a talking equipment are installed distant from each other by activating a copying machine while a communication line is connected to the talking equipment. CONSTITUTION:When an activation command is received in a state that a talking equipment 13 connecting to a talking equipment connection section 9 acquires a communication line 12, and when an original is set on a read section 4 before the talking equipment 13 acquires the communication line 12, a switch of a communication section 7 connects the communication line 12 to a picture communication equipment 11 to transfer the picture communication mode.

Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To detect abnormality in the feeding of film caused by an instantaneous shock in the midst of feeding the film by providing a film feeding means and a shock detecting means detecting the shock in the midst of feeding the film. SOLUTION: A feeding motor 5 is driven through a feeding motor driving device 4, so that the feeding of the film is started. A magnetic information recorder is driven based on a signal outputted from photoreflectors 9 and 10 so as to write magnetic information on the film. In order to examine whether the shock is given to a camera in the midst of recording, a shock detecting device 7 and an acceleration sensor 8 are actuated to measure a shock value A. The measured shock value A is compared with a threshold B. When the value A is smaller than the threshold B (A<=B), it is decided as a situation that trouble is not caused. When the value A is larger than the threshold B (A>=B), it is decided as a situation that the trouble is caused.  By rewinding frames on which magnetic recording is not accurately performed at present, the film is set so that magnetic recording can be performed again and a warning on the effect is displayed by a display device 11.
