Title: Magnetic recording and reproducing device
Inventor: MOMOKI MOTOYASU
IPC: G11B15/00
Filed: 1983-07-26
Abstract: PURPOSE:To detect quickly and accurately tape sag by setting two tape guides containing reflective photosensors in opposition to each other at the outside of the driving path of a magnetic tape and detecting the tape having the sag along the tape guide. CONSTITUTION:Guide members 41 and 42 are set oppositely to each other as shown in the figure at the outside of the driving path of a magnetic tape 1. Therefore, the tape 1 is set along the members 41 and 42 in case the tape 1 has the sag as shown by a broken line at the exit side of a capstan 18 and a pinch roller 19 and outside the tape driving path. This tape sag is immediately detected by the reflective photosensors 43 and 44 which are provided to the members 41 and 42 respectively. Thus the drive of the tape 1 is stopped immediately and hereafter the tape 1 is rewound for a few seconds to get rid of the sag. In such a way, even a small amount of the tape sag can be eliminated quickly. This device prevents the damage of the tape 1 and the recording/reproducing device.

IPC: G11B7/09
Filed: 1995-06-02
Abstract: PURPOSE: To improve the ability of an optical pickup to follow up the focusing and tracking directions of an objective lens and to reduce the energy consumption. CONSTITUTION: In suspensions 15a and 15b for supporting the objective lens 11 of an optical pickup 10, the tracking direction width dimension and the focusing direction thickness dimension on the objective lens supporting side are made small by means of half etching, etc., so as to provide a dimension difference.

Abstract: PURPOSE:To prevent invasion of mold resin to the inside of a projecting part by forming a projecting part along the whole periphery of the face to mount a chip or bond wires, of an electrode, and force-bonding the projecting part to a mold at the time of injection molding. CONSTITUTION:When resin molding is executed by injection after electrodes 91 to 94 of a load frame 9 are mounted on a lower mold 2 with the side to mount a chip or bond wires down, the pressure of resin mold loaded to the electrodes 91 to 94 concentrates on the projecting parts 91a to 94a, and the ends of the projecting parts 91a to 94a are force-bonded strongly to the lower mold 2. As a result, the resin is checked by the projecting parts 91a to 94a, and prevented from invading the inside. Accordingly, the electrodes 91 to 94 faces cease to be contracted by the resin, and chip mounting and wire bonding in the next process can be carried out without hindrance.

Abstract: PURPOSE:To positively detect an end of a paper, by so constituting that, when said paper is set in a hopper, a carrier is moved corresponding to the position where said paper is set, whereby a sensor is always present at a position opposed to said paper. CONSTITUTION:A processor 10 supervises the movement of a carrier 16 to a position of digit designated by a digital switch 25. When the movement is completed, the processor 10 rotates a platen 4 through a line changing control circuit 12. A paper 1a or 1b is accordingly drawn out from a hopper 2 and guided between a sensor 5a or 5b, and the platen 4. The sensor 5 is of a reflecting type. When the paper 1a or 1b passes, the sensor 5 detects an end of the paper by the change of the reflecting stage of light, generating a signal via an input port 17 to the processor 10. The processor 10 controls the line change control circuit 12 on the basis of the detecting signal from the sensor 5 such that the paper 1a or 1b is stopped after it is sent a predetermined distance from the position of the sensor 5a or 5b. Therefore, regardless of the width or setting position of the paper, the end of the paper can be positively detected.
