Abstract

The mechanism retracts an idler roller and sound head for more convenient loading of magnetic belt in a dictation machine. Dictation machine 1, at A includes cover 2 with control assembly 3 that is slideably mounted within cover 2 for movement as indicated by arrow 4 to load and unload magnetic belt media 5. Machine 1 includes control panel 6 for controlling modes of operation. Scanning assembly 7 includes sound head 8 mounted on pivot assembly 9 that is swingably mounted for movement at 10 and 11 toward and away from belt 5 to enable loading and unloading of such belt. The mechanism moves idler roller 12 and sound head 8 somewhat farther away from roller 13 when pivot assembly 9 is in the upper position to provide greater clearance for movement of belt 5 onto the various rollers during loading.

Idler Roller and Sound Head Retract Mechanism

The mechanism retracts an idler roller and sound head for more convenient loading of magnetic belt in a dictation machine. Dictation machine 1, at A includes cover 2 with control assembly 3 that is slideably mounted within cover 2 for movement as indicated by arrow 4 to load and unload magnetic belt media 5. Machine 1 includes control panel 6 for controlling modes of operation. Scanning assembly 7 includes sound head 8 mounted on pivot assembly 9 that is swingably mounted for movement at 10 and 11 toward and away from belt 5 to enable loading and unloading of such belt. The mechanism moves idler roller 12 and sound head 8 somewhat farther away from roller 13 when pivot assembly 9 is in the upper position to provide greater clearance for movement of belt 5 onto the various rollers during loading. Roller 12 is shown in closed condition at B. Roller 12 has the lower end fixed to slider member 14 that is spring-loaded by spring 15, at D, to the left which moves the lower end of roller 12 farther to the left, as at C, to provide a greater clearance between roller 12 and pad 16 at gap
17. Slider 14 cooperates with cam member 18 mounted on the frame of machine
1. Sound head 8 carries retract bracket 19 engagable with slider 14 to also retract sound head 8 under the influence of spring 15 when pivot assembly 9 is in the raised condition as at A.
