Abstract
1,254,639. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORP. 25 June, 1969 [15 July, 1968], No. 32190/69. Heading B6F. An encoding keyboard, comprises a plurality of keys operating a plurality of control members 64, 72 movable from non-select to select position by drive shaft 40 and which have an interlocking device (15) as described in Specification 976,473, one of the keys 60 is interconnected with an auxiliary lever 70 so that it works in opposite direction to the lever key 60, i.e. when key 60 is depressed the lever 70 is raised and when released the lever 70 is depressed. Magnetic reed switches operated by the presence of a pivoted shunt 17 or shunt 92 accurately signal the status of the keyboard. Operation of the auxiliary key 60 causes actuation of control member 64 and the end of a horizontal arm 82 of a transfer link is moved forwardly. An upstanding part 84 co-operatively engages an inclined camming bracket 74 attached to the auxiliary lever 70 which is thereby raised against the pull of bias spring 73. Release of the key lever 60 causes opposite effect and lever 70 is depressed, but this time a dobber 71 engages the actuator 72 which is thereby pushed into engagement with the drive shaft 40 and the appropriate signal is given by the magnetic switch 19.
