Braking mechanism for document table drive means in a copying apparatus

摘要

Disclosed is an image forming apparatus of shell type which is divided into an upper unit and a lower unit, said upper unit being made rockable with respect to the lower unit and slidably provided with a document tale intended to have a document placed thereon. To the document table, there is connected a driving mechanism which is intended to cause the document table to slide with respect to the upper unit. This driving mechanism is provided with a braking mechanism which is intended to cause a braking force to act on the document table at the time when the upper unit is rocked with respect to the lower unit. The braking force of this braking mechanism acts to prevent the document table from being impulsively allowed to fall when the upper unit has been rocked.
