Abstract

Mounting holes in print shield 10 fit over L-shaped pins 12 on card holder 14. This prevents accidental dislodging of the print shield 10. The load of spring 18 keeps the mounting pins 20 firmly loaded into the slots 24 on the card holder 14, thus preventing accidental disengagement.

Print Shield

Mounting holes in print shield 10 fit over L-shaped pins 12 on card holder 14. This prevents accidental dislodging of the print shield 10. The load of spring 18 keeps the mounting pins 20 firmly loaded into the slots 24 on the card holder 14, thus preventing accidental disengagement.

When the operator desires to release the card holder 14 for cleaning, print shield replacement, or other reasons this can be accomplished by depressing the tab 16 on the release lever and lifting out the card holder 14. For reinsertion, depressing tab 16 causes the mounting pins 20 to spread apart to accept holder 14 and rotates the tape retractor 22 in a forward direction, to pull the correction tape and the ribbon out of the way and allow a less restricted area in which to insert the card holder 14.

Referring now to Figs. 2a and 2b, a pop-up version is illustrated. An applied force at point 30 rotates lever 32 about point 34 of lever 36 removes card holder 14 from stud 20. Continued force at point 30 pivots the whole assembly about point 38 to the accessible position shown in Fig. 2.

Reassembly of card holder 14 and print shield is accomplished by setting card holder 14 on stud 20 (Fig. 2b). Card holder 14 is guided into position and will stop on stud 40. Continued force on the top of card holder 14 will snap the card holder into stud 40 and return the assembly to the Fig. 2a rest position.
