Title: Voice alarm apparatus for car
Inventor: TSUNODA MASAICHI
IPC: B60Q11/00
Filed: 1979-10-03
Abstract: PURPOSE: To provide a simple apparatus which permits information on voice by starting regeneration through the contact of a record disc with a needle by alarm instruction signal and separating the needle from the record disc and returning to the initial position when one generation terminates and releasing self-retention of a motor power feeding circuit.  
     CONSTITUTION: When a needle arm 12 and a return arm 16 are at the initial position shown in the figure, if a record disc 1 is revolved through a belt 4 by a motor 3, a needle 10 is transferred relatively towards the end point from the start point of the groove on the disc 1. During this time, the voice information recorded on the groove is taken-out as mechanical vibration by the needle 10, and the vibration is transmitted from the needle arm 12 to a speaker cone 11 and directly converted to voice. As the needle 10 comes close to end point of the groove 2, the top end of a return arm 16 interlocks with cam threads 26, and the disc 1 is pushed down by the arm 16. Accordingly, the needle 10 is separated from the groove, and then the needle arm 12 is automatically returned to the initial position by a spring 14.

Title: Head device for discharge recording
Inventor: KOMATSU FUMITO
IPC: B41J2/425
Filed: 1989-05-19
Abstract: PURPOSE:To compensate the uneven wear of needle electrodes by a method wherein the resiliency of a projection pressing spring formed integrally with each of the needle electrodes makes the needle electrode protrude outside a head block and abut on a recording medium independently. CONSTITUTION:When a discharge recording head 15 is loaded on a printer to be made to conduct a recording action, the large undulation of a card C is corrected by a lower end surface 15c of a head block body 15A. If the skew cannot be corrected, needle electrode bodies 16b having the habit of protruding independently of each other positively abut on a breaking layer on the top surface of the card C and are pressed into the head block body 15A by the contraction of an intermediate part 16d of a pressing spring 16f. Such a phenomenon independently occurs for every needle electrode body. Therefore, the omission of dots caused by a failure in abutting a needle-form tip end part 16a against the card that may be attributed to a partial undulation of the card C in a recording action or the uneven wear of the needle electrode group can be prevented from occurring.
