Problems solved by technology

[0014] [14] The requirements of high-speed transfer printers for the deceleration, acceleration, speed and position accuracy of the belt make it difficult for many known drive mechanisms to obtain acceptable performance in the case of high reliability
Similar restrictions are imposed in applications other than high-speed printers, such as drives used in label printers adapted to use labels separated from label sheets

Embodiment Construction

[0034] [34] Reference figure 1 , which schematically illustrates a belt drive suitable for use in a thermal transfer printer according to the present invention. The first shaft 1 and the second shaft 2 support a supply reel 3 and a take-up reel 4, respectively. The supply reel 3 is initially wound with a roll of unused tape, while the take-up reel 4 is initially not carrying any tape. As the tape is used, the used portion of the tape is transferred from the supply reel 3 to the take-up reel 4 . A movable print head 5 is provided which is movable relative to the belt 6 at least in a first direction indicated by arrow 7 . The belt 6 extends from a supply reel 3 around rollers 8 , 9 to a take-up reel 4 . The path followed by the belt 6 between the rollers 8 and 9 passes in front of the print head 5 . When printing starts, the substrate on which the printed pattern is deposited comes into contact with the belt 6 between the rollers 8 and 9 and the belt 6 is inserted between th...

Abstract

A tape drive comprising two motors (12, 13), two tape spool supports on which, spools (3, 4) of tape may be mounted, each spool being drivable by a respective one of said motors, and a controller (14)for controlling the energisation of the motors such that the tape may be transported in at least one direction between spools mounted on the spool supports. The controller is configured to store a plurality of motor control data items, each data item being associated with a respective tension value. The controller is operative to monitor tension.in a tape being transported between spools mountedon the spool supports, read a motor control data item based upon said monitored tension, generate a motor control signal based upon said read motor control data item, and apply said motor control signal to at least one of the motors.

Description

technical field [0001] [1] The present invention relates to a belt drive device. Such a tape drive may form part of a printing apparatus. In particular, such a belt drive may be used in transfer printers, ie printers that use ink carried by a carrier. Background technique [0002] [2] In a transfer printer, a belt that is commonly called a printer belt and that carries ink on one side of it is placed within the printer so that the printhead can contact the other side of the belt so that ink can be transferred from the belt to, for example, Paper or flexible film target substrates. Such printers are used in many applications. Industrial printing applications include thermal transfer label printers and thermal transfer encoders, which print directly onto substrates such as packaging materials made from flexible ink or card. [0003] [3] The ink ribbon is typically delivered to the end user in the form of a roll wound onto a core. The end user pushes the core onto the spoo...
