A case of the cartridge is provided with a hole for exposing a free end portion of the coupling to an outside of the cartridge, and a retracted portion provided in downstream of the hole with respect to the mounting direction of the cartridge. When the cartridge is mounted to a main assembly of the printer, the coupling guide enters the retracted portion from which the coupling member has retracted.

摘要： A recording apparatus performs recording on a recording medium by using a tray having a plurality of slots, and includes a reception unit receiving information for specifying a detection position of the recording medium in a slot of the tray from an external apparatus, and a specification unit to specify the detection position. In addition, a control unit controls the recording apparatus so that, in a case where the recording medium is arranged in a first slot and no recording medium is arranged in a second slot, recording processing is performed on the recording medium arranged in the first slot, and recording processing is not performed in association with the second slot. Detection processing to detect a recording medium is not performed for a third slot which is not specified, and detection processing is performed for the first and second slots which are specified.
