ABSTRACT:
There is provided a recording apparatus capable of bringing a delivery tray to an open state automatically when a sheet material is conveyed without the need for a solenoid to open the delivery tray, and preventing the delivery tray from opening inadvertently except during recording. The recording apparatus includes a delay mechanism having plural ring members rotatable with some delay in sync with a delivery roller, and a control mechanism having plural link members, and plural elastic members. Plural cam portions rotatable together with the plural ring members, and a phase control unit for controlling the phases of the plural cam portions are provided in the delay mechanism. One link member of the control mechanism is connected to a delivery tray. When the phases of the plural cam portions match, the delivery tray is opened through the control mechanism by a drive of the delivery roller.
