A waterproof cover has a first cover portion made of a waterproof material for removable connection to and covering a part of a device that has a recording portion for performing recording on a recording medium that is dischargeable from the device. A second cover portion is made of a flexible waterproof material for covering the device and for removable connection to the first cover portion to form an opening portion through which the recording medium passes when discharged from the device. Connecting members removably connect the second cover portion to the first cover portion. Positioning members position the second cover portion relative to the first cover portion prior to connection of the second cover portion to the first cover portion by the connecting member.
