2. Description of the Related Art Conventionally, as this type of tape cartridge device, a device mounted on a tape printing device described in Japanese Patent Application Laid-Open No. 10-6579 is known. In this tape printing apparatus, an opening / closing lid is provided on the upper surface of the apparatus main body, and a cartridge mounting portion for detachably mounting a tape cartridge is formed in the opening / closing lid. A print head for printing on the tape fed from the tape cartridge, a platen for receiving the print head, and a take-up reel drive shaft for winding the ink ribbon are provided upright at the cartridge mounting portion.

A platen is rotatably supported by a platen holder via a platen shaft. The platen holder is rotatably supported at its upper end by a chassis and at its lower end by a base frame. The platen holder has an arm extending at the tip end thereof engaged with the cam. When the cam rotates in conjunction with the closing of the opening / closing lid, the platen holder rotates and the platen moves to the print head. Abut. On the other hand, the print head is supported by a head holder, and the lower end of the head holder is supported by a base frame.
A pin is provided upright on the upper end surface of the head holder, and a bridging member provided on the upper end surface of the chassis so as to be movable up and down is engaged with the pin. That is, by closing the opening / closing lid, the bridge member is tilted and the engagement hole of the bridge member engages with the pin. As described above, the separation distance between the platen and the print head is appropriately maintained by the base frame between the lower ends, and is appropriately maintained by the bridge member between the upper ends. Thereby, the platen and the print head can be brought into contact with each other with a uniform pressing force in the vertical direction, thereby preventing printing unevenness and skew of the tape and the ink ribbon.
Further, the take-up reel drive shaft has a lower end erected on a base frame, and is supported by the cantilever.

[0004]

In such a conventional tape cartridge device, the distance between the platen and the print head is regulated by a single base frame between the lower ends through respective holders. , Relatively,
Although high accuracy is maintained, there is a problem that the accuracy is reduced between the upper end portions because it is regulated by two members, the chassis and the bridge member. In particular, since the bridge member is attached to the chassis so that it can be turned upside down (rotatable), it has a structure in which high dimensional accuracy is difficult to be obtained due to dimensional crossing or rattling of the rotating portion. Moreover, since the engagement hole of the bridge member and the pin of the head holder are engaged in conjunction with the opening and closing of the opening / closing lid, the pin has to be loosely fitted into the engagement hole. High dimensional accuracy is difficult to obtain. Therefore, it is practically impossible to precisely control the separation distance between the upper end portion of the platen and the print head, which causes uneven printing and skew of the tape and the ink ribbon. Further, in order to have a platen and a print head at both ends, a chassis and a bridge member are required in the cartridge mounting portion, and there has been a problem that the structure is complicated. Similarly, since the take-up reel drive shaft is supported by the base frame in a cantilever manner, when winding a wide ink ribbon or the like, the drive shaft itself tilts, causing wrinkles on the ink ribbon or tilting of the ink ribbon. There were problems such as winding up in a folded state.
