Abstract

A tape cartridge or the like which can be pulled out of a cartridge loading section while maintaining a loading posture is to be provided. A tape cartridge is configured to be able to be loaded in and unloaded from a tape printing device. The tape cartridge includes a tab portion which is gripped at least at the time of unloading. The tab portion is arranged at or near a position where pull-out resistance due to unloading is balanced within a plane intersecting with an unloading direction.

First claim

The invention claimed is:

1. A tape cartridge configured to be able to be loaded in and unloaded from a tape printing device, the tape cartridge comprising
a tab portion which is gripped at least at a time of unloading, and
a recessed portion which is provided in a case wall situated on a front side in a direction of the unloading and in which the tab portion sinks,
wherein the tab portion is arranged at or near a position where pull-out resistance due to unloading is balanced within a plane intersecting with the direction of the unloading, and
wherein the tab portion is provided in the recessed portion in such a way as to be able to rise and fall between a rise-up position where the tab portion protrudes from the recessed portion and a fall-down position where the tab portion sinks in the recessed portion.

2. The tape cartridge according to claim 1 , wherein the recessed portion is provided with a rise-up energizing portion which energizes the tab portion toward the rise-up position.

3. The tape cartridge according to claim 1 , wherein the tab portion has a rough portion for slip-proofing.

4. A tape printing device comprising a cartridge loading section in which the tape cartridge according to claim 1 is loaded in an unloadable manner.

5. A tape cartridge configured to be able to be loaded in and unloaded from a tape printing device, the tape cartridge comprising
a tab portion which is gripped at least at a time of unloading, and
a recessed portion which is provided in a case wall situated on a front side in a direction of the unloading and in which the tab portion sinks,
wherein the tab portion is arranged at or near a position where pull-out resistance due to unloading is balanced within a plane intersecting with the direction of the unloading, and
wherein the tab portion is provided in the recessed portion in such a way as to be able to advance and retreat between a gripping position where the tab portion protrudes from the recessed portion and a non-gripping position where the tab portion sinks in the recessed portion.

6. The tape cartridge according to claim 5 , wherein the recessed portion is provided with a protrusion energizing portion which energizes the tab portion toward the gripping position.

7. The tape cartridge according to claim 6 , further comprising a lock mechanism which holds the tab portion at the non-gripping position.
