A recording device includes a recording unit configured to perform recording on a recording target medium, a first conveyance path that is a conveyance path of the recording target medium including an opposite position that faces the recording unit, and conveyance of the recording target medium in a first direction, a second conveyance path being coupled to the first conveyance path at a position downstream of the recording unit in the first direction, the second conveyance path being coupled to the first conveyance path also at a position upstream of the recording unit in the first direction and configured for conveyance of the recording target medium to the first conveyance path with a surface of the recording target medium inverted, and an insertion port configured to enable insertion of a recording target medium as an insertion material to the second conveyance path from outside.

A sheet feed device comprises a first conveyance path and a second conveyance path which are different sheet conveyance paths, and a conveyance path merging section for merging the first conveyance path and the second conveyance path together. At least one of the first conveyance path and the second conveyance path includes an upstream side roller that feeds sheet to downstream side in a conveyance direction. The conveyance path merging section comprises a conveyance roller pair that conveys the sheet fed from the first conveyance path and the second conveyance path through a nip; a variable mechanism that makes an arrangement angle of one roller of the conveyance roller pair to the other roller thereof variable; and a transmission mechanism that transmits a driving force from the upstream side roller provided in one of the first conveyance path and the second conveyance path to the variable mechanism.

For a printing apparatus, a first conveyance speed for a first printing medium is determined according to first print data to be printed on the first printing medium and a second conveyance speed for a second printing medium is determined according to second print data to be printed on the second printing medium that follows the first printing medium along a conveying path. In a case where the second conveyance speed is equal to the first conveyance speed, a conveyance operation of the second printing medium is started before the first printing medium is discharged from the conveying path. In a case where the second conveyance speed is different from the first conveyance speed, the conveyance operation of the second printing medium is started after the first printing medium is discharged from the conveying path.

Provided is a paper sheet replenishing box (paper feed device) for replenishing reserve fund in each circulation-type paper sheet storage unit, wherein paper sheets of each denomination can be replenished from one paper sheet replenishing box in which paper sheets of different denominations having different sizes are accommodated together to a circulation unit of the respective circulation-type paper sheet storage units. The paper sheet replenishing box includes a first tray piece 201 in which a plurality of pieces of first paper sheets P1 are placed in a stacked state, a second tray piece 211 arranged immediately below the first tray piece, on which a plurality of pieces of second paper sheets P2 having a different longitudinal dimension from that of the first paper sheet are placed in a stacked state, and rear-end regulating members 204 and 214 that align front end positions in a transport direction of respective paper sheet bundles to predetermined positions. After all the first paper sheets in a bundle on the first tray piece have been fed by a feed unit 160, an uppermost surface of the second paper sheets in a bundle on the second tray piece becomes a state capable of coming in contact with the feed unit.
