Abstract
An ink ribbon cassette has a cassette case in which a thermal transfer ink ribbon subjected to a plurality of printing operations on the same surface at the same position. The case is alternately loaded in a thermal printer in a first loading posture and in a second loading posture which is a reversed posture to the first one to change a feed direction of the ribbon in the printer. A count display unit is provided on the case to record the number of times of use of the ribbon and display the number.
Claims8
A multiprinting thermal transfer ink ribbon cassette, comprising:
- a cassette case having a circumferential surface and at least one side surface;
- a thermal transfer ink ribbon stored in said cassette case and subjected to a plurality of printing operations on the same surface at the same position thereof;
- said multiprinting thermal transfer ink ribbon cassette being alternately loadable in a printing apparatus having a thermal head in a first loading posture and in a second loading posture which is a reversed posture with respect to the first loading posture so as to change a feed direction of said thermal transfer ink ribbon in said printing apparatus;
- and
- count displaying means for recording a counted number of times of use of said thermal transfer ink ribbon and for displaying the counted number;
- said count displaying means comprising an operation member extending out from an outer surface of said cassette case, said operation member being manipulable to increase the displayed count;
- and
- said count displaying means further comprising a rotary member rotatably supported about a longitudinal axis thereof in said cassette case, said operation member being fixed coaxially with said rotary member so as to be rotated together with said rotary member;
- said operation member being exposed from at least one of said circumferential surface of said cassette case and said at least one side surface thereof;
- a plurality of consecutive numbers circumferentially marked on at least part of a circumferential surface and at at least part of one end face of said rotary member;
- openings formed in said circumferential surface of said cassette case in said at least one side surface thereof so as to correspond to at least the part of said circumferential surface of said rotary member and at least the part of said one end face thereof;
- and intermittent stopping means for stopping rotation of said rotary member when one of said plurality of numbers is exposed to a corresponding one of said openings.
