A drive device to which a recording tape cartridge is loaded, and which can record information in a recording tape and playback information recorded in the recording tape, the recording tape cartridge including:
- a case;
- a reel accommodated in the case, having a reel hub around which the recording tape is wound, and having an engaging portion formed on a bottom of the reel hub;
- a brake member which is non-rotatably provided in the case, which approaches and moves away from the bottom of the reel hub, and which can be located in a rotation locked position where the brake member engages with the engaging portion and a rotation permitted position where the engagement state between the brake member and the engaging portion is released;
- and a reel gear formed on the reel and exposed from a gear opening formed in the case, the drive device comprising:
- a rotating shaft having a drive gear which meshes with the reel gear and rotates the reel;
- an operating member which pushes up the brake member to the rotation permitted position;
- and
- an adjusting mechanism which adjusts a projecting height of the operating member.
A method for manufacturing a drive device to which a recording tape cartridge is loaded, and which can record information in a recording tape and playback information recorded in the recording tape, the recording tape cartridge including:
- a case;
- a reel accommodated in the case, having a reel hub around which the recording tape is wound, and having an engaging portion formed on a bottom of the reel hub;
- a brake member which is non-rotatably provided in the case, which approaches and move away from the bottom of the reel hub, and which can be located in a rotation locked position where the brake member engages with the engaging portion and a rotation permitted position where the engagement state between the brake member and the engaging portion is released;
- and a reel gear formed on the reel and exposed from a gear opening formed in the case, the method comprising:
- forming a rotating shaft having a drive gear which meshes with the reel gear and rotates the reel,
- forming an operating member which pushes up the brake member to the rotation permitted position, and
- forming an adjusting mechanism which adjusts a projecting height of the operating member.
