Abstract
The pinch pressure-adjusting device comprises a pair of pinch roller-supporting members which rotatably hold the paired pinch rollers and whose pivotal shaft is set in parallel with the rotary shafts of said paired pinch rollers; a first urging member, one end of which is fixed to one of the paired pinch roller-supporting members; a second urging member, one end of which is fixed to the other of the paired pinch roller-supporting members; and a movable member which is fixed to the other end of the first urging member and to the other end of the second urging member. The movable member is shifted between a first position in which the movable member is more spaced from one of the paired pinch roller-supporting members than from the other thereof and a second position in which the movable member is more spaced from the other of the paired pinch roller-supporting members than from the one thereof. When the tape travels in a direction from the other of the paired pinch rollers to the one thereof, the movable member takes the first position to cause the first urging member to produce a greater urging force than the second urging member, and, when the tape travels in the opposite direction between the paired pinch rollers, the movable member takes the second position to cause the second urging member to produce a greater urging force than the first urging member.
