Abstract

908,200. Magnetic sheet recorders; associated working. TOKYO DENKI KAGUKU KOGYO KABUSHIKI KAISHA, and HOSHINO, Y. Sept. 10, 1958 [Sept. 12, 1957], No. 43488/60. Divided out of 889,401. Class 40 (2). Indexing means for the machine described in Specification 889,401 comprise a solenoidoperated pen 52, mounted to traverse the margin I of a record to produce marks P 1 , P 2 , and electrical contacting means 55 to sense means 54 provided in accordance with some or all of the ink markings. Visual marks 35, 35<SP>1</SP> may be provided to indicate the start and finish of the recording, while the means 54 may be used to halt the machine after each of a number of short recordings sharing one sheet or to control the operation of a photographic slide-changer in accordance with associated sound recordings. The means 54 may be foil strips or holes, through which the contact 55 can engage a conductive strip secured to the record pressure plate (Fig. 1, not shown).
