Ink ribbon cassette, ink ribbon cartridge, printing device and printing device control method

Abstract

Provided is a printing device for which configuration is simplified and with which the ink ribbon can be appropriately fed in both directions between a supply roll and a take-up roll on which the ink ribbon is wound. The printing device (1) is provided with: a supply roll (4), a take-up roll (5), and a power transmission mechanism (31) for transmitting motive power from a drive source (30) to the supply roll (4) and the take-up roll (5). If the direction in which the take-up roll (5) winds the ink ribbon (3) is called the ribbon winding direction and the direction in which the supply roll (4) winds the ink ribbon (3) is called the ribbon rewinding direction, the power transmission mechanism (31) is provided with: a one-way clutch for transmitting the driving force of the drive source (30) to the take-up roll (5) in the ribbon winding direction and blocking the transmission of the driving force of the drive source (30) to the take-up roll (5) in the ribbon rewinding direction; and a one-way clutch for transmitting the driving force of the drive source (30) to the supply roll (4) in the ribbon rewinding direction and blocking the transmission of the driving force of the drive source (30) to the supply roll (4) in the ribbon winding direction.

Description

technical field [0001] The present invention relates to an ink ribbon holder having a supply roller and a take-up roller on which an ink ribbon is wound, and a printing device having the ink ribbon holder. [0002] Also, the present invention relates to a printing apparatus having a main body portion on which an ink ribbon holder is detachably mounted, and to a frame having an ink ribbon holder and to which the ink ribbon holder is detachably mounted body printing device. Furthermore, the present invention relates to a method of controlling a printing apparatus having an ink ribbon holder and a frame on which the ink ribbon holder is detachably mounted. Background technique [0003] Conventionally, there is known a thermal printing type printing device that transfers ink of a heated ink ribbon to a card conveyed on a card conveyance path to perform printing (for example, refer to Patent Document 1). The printing device described in Patent Document 1 has an ink ribbon holde...

Problems solved by technology

In addition, in this printing device, the ink ribbon holder does not have a cover covering the take-up roller, and the used ink ribbon wound on the take-up roller is exposed to the outside when the ribbon holder is detached from the main body.

[0012] On the other hand, in a thermal printing type printing device such as the printing device described in Patent Document 1, since the ink having the same shape as the image printed on the card is peeled off from the ink ribbon, the ink after printing The tape (used ink ribbon) has peeling traces of ink remaining in the same shape as the image printed on the card
