Pack holder for postcards and envelopes

摘要

Disclosed is an paper feeding device or a pack holder capable of preventing noise or a misfeeding when printing envelopes or postcards. The pack holder can be adjusted to feed standard size paper or postcards and envelopes. A sliding plate is used when feeding postcards and envelopes so that the last postcard or envelope in the stack can be fed into the machine successfully. The sliding plate allows only one of the two feeding rollers to make contact with a friction pad during the feeding of postcards and envelopes.
