PURPOSE:To attain a small sized counter for recording conveniently the number of recording times, by providing two turning rods in parallel with each other in perpendicular to the turning shaft direction in a cassette, turning both rods in the same phase and stretching a flat belt having a scale between the two turning rods. CONSTITUTION:A recording and reproducing medium 5, a turning rod 6 and a counter strip 8 are provided in the inside of the cassette 4 and the strip 8 is stretched to the two turning rods 6 so as to clip the recording medium 5. One of slide bearings 7 is led to the counter side face, a groove 10 to be connected to a rod 9 is provided at the bottom of the turning rod 6 stored in a bearing, a groove 10 is provided at the tip of the rod 9 and the turning rod 6 and the groove 11 are mated. The rod 9 is inserted to the turning shaft at the loading of the cassette 4 and when recording is performed from the device to the medium 5, the turning rod 6 turns by a prescribed phase angle, and when the rod 9 is turned by a solenoid or a motor, the strip 8 is moved at each time by a prescribed interval and the number of recordings is read from the scale on the strip 8. |
