An anti-stuck driving device comprises: a movable blade, a movable blade driving unit, and a controller. The movable blade driving unit comprises a transmission assembly, a motor configured to drive the transmission assembly, and a connecting element connected between the transmission assembly and the motor. The transmission assembly links the movable blade moving back and forth linearly. The controller connects to the motor. When the movable blade is stuck, the controller controls the motor to drive the connecting element to rotate in reverse to separate the transmission assembly and the connecting element, and release a resistance of the transmission assembly. The present invention also discloses a printer using the anti-stuck driving device with malfunction repairing.

A tape cassette includes: a cassette casing; and a tape roll that is a roll of a tape extending in a lengthwise direction and a widthwise direction. The tape includes: a subject surface exposed in a thickness direction; and a first image provided on the subject surface and indicating first information. The tape roll has: a first end portion located at an inner portion of the tape roll in a radial direction of the tape roll; and a second end portion located at an outer portion of the tape roll in the radial direction. The first information relates to an amount of a portion of the tape which is located on a first-end-portion-side of a reference position in the lengthwise direction. The reference position is located on the first-end-portion-side of the first image in the lengthwise direction on the tape at a particular distance from the first image.
