Claims

[Claims for Utility Model Registration] A brake member for braking a pair of reel stands fitted to a supply reel and a take-up reel of a tape cassette, a cam plate that is driven when switching modes, and a cam portion of the cam plate. A reel stand brake mechanism comprising: a sliding member that is driven in sliding contact and presses the brake member in the brake release direction; and a solenoid that holds the sliding member in a brake release position; A brake mechanism for a reel stand, wherein a relief portion is provided in a cam portion of the cam plate so that a sliding member does not come into sliding contact with the cam plate.
