Abstract: Operation of a pushbutton or key mechanism by the operation of a single pushbutton or key through circuitry which may include fiber optics signals all keys on the keyboard included in the particular chord. The device may be built in or simply attached to the keyboard instrument. The keys are spring, and string or wire operated to return a key to its inoperative position when the next key is pressed down.
Abstract: An automatic repeat system for magnetic tape recorders and reproducers is disclosed which is provided with an automatic repeat mechanism adapted to set the magnetic tape to its reproducing or rewinding status in response to the resetting of the reproducing lever or rewinding lever to be effected by means of an automatic stop mechanism serving the purpose of resetting the reproducing lever or rewinding lever upon termination of the reproducing or rewinding motion.
Abstract: A transcription mechanism for use with tape players of the type having control members movable between neutral and operative positions, the mechanism including a controller positionable in operative relationship with the control members, a remote foot pedal and a cable interconnecting the controller and the foot pedal.
Abstract: The selection console of the present invention affords a plurality of finger-actuated push buttons which move a short distance to actuate the item-selecting mechanism of a vending machine. The console utilizes a single solenoid to unlock the selector mechanism in response to the energization of the coin accumulator and price mechanism and actuation of a selection price switch. Further, the machine permits the items in the vending machine to be priced at different values without the necessity of separate mechanisms, except for a switch to be actuated by each price bar. Once a price has been selected, the locking mechanism of the console of this invention prohibits one from changing to a different item.
Abstract: A pushbutton assembly has an actuating arm with a body portion and an outer end portion connected to the body portion by a narrowed portion. A pushbutton having a cavity and a slot leading from the rear wall to the cavity is retained on the arm by slipping the arm through the slot until the end portion enters the cavity, then twisting the end portion slightly around the longitudinal axis of the arm. The pushbutton can be released by realignment of the arm end portion with the body portion.
Abstract: In a magnetic recording/reproducing apparatus having a plurality of push-buttons for directing changeover of tape drive modes, a simple and compact mechanism for effecting mode changeover including an idler, a reciprocating member, sliding actuating bars and an alternative-selection mechanism, all operated by the motive force from a motor-driven capstan. The idler is mounted for movement into and out of contact with a wheel mounted for rotation with the capstan and the reciprocating member moves responsive to the movement of the idler. The idler can be carried to a position spaced from the capstan wheel by the movement of the reciprocating member. Actuating bars, one associated with each push-button, are engaged and disengaged with the reciprocating member by an alternative selection mechanism.
Abstract: A push button type tuning device comprising a plurality of tuning coils each being made tunable with any of a plurality of receiving broadcast bands, selection levers any of which is selected and pushed in response to a desired broadcast band by operating each push button secured to a pointed end of each selection lever and tuning cores each being adapted to insert into or draw from any of said coils by the pushed selection lever.
Abstract: A multiple switch in accordance with the present invention comprises a plurality of pushbuttons that are movable between an extended and a depressed position and are biased toward the extended position. The pushbuttons are paired and each pushbutton pair is associated with an individual lockout, a releasing-latching bar (RL bar) that is common to all of the pairs, and an individual releasing-nonlatching and releasing-latching bar (RNRL bar). Each pushbutton interacts with all three members when it is depressed.The lockout permits either pushbutton of the associated pair to be depressed individually but prevents both pushbuttons from being depressed simultaneously. As any pushbutton is depressed, the RL bar acts to release all pushbuttons previously depressed and latches the activated pushbutton in its depressed position.
