ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a tape cartridge of a recording and reproducing apparatus, which is installed in and used for the recording and reproducing apparatus provided with a reel for carrying out winding and rewinding of a built-in tape and a recording and reproducing system comprised of a tape cartridge and a recording apparatus.
2. Description of the Related Art
In a conventional recording and reproducing apparatus, in order to wind a tape at a time of recording, to feed out the tape at a time of reproducing, and to carry out a fast rotation as well as rewinding, a capstan motor to drive a capstan into rotation on which a tape is wound and a reel motor to drive into rotation a winding reel as well as a feeding-out reel were needed.
A capstan motor previously provided in a recording and reproducing apparatus becomes comparatively large-sized, and a tape run has been directly badly affected by shaking and rotational ununiformity of a capstan shaft due to the large-size of the motor. So, in order to realize a stable rotation without shaft shaking and rotational ununiformity, a compensating mechanism and the like become necessary. Further, the conventional recording and reproducing apparatus needed an extra reel motor and as a result, the whole apparatus became more large-sized, thereby incurring a problem in terms of the manufacturing costs.
SUMMARY OF THE INVENTION
The present invention is implemented in view of the present situation of the tape run mechanism in the above-mentioned recording and reproducing apparatus and its object is to propose a tape cartridge and its recording and reproducing apparatus, in which the tape cartridge is installed in and used for the recording and reproducing apparatus capable of stably running a tape at a predetermined speed with a small-sized, light weighted arrangement and at a low cost.
According to an aspect of the present invention, there is provided a tape cartridge for use in a recording and reproducing apparatus, which comprises:
a housing incorporating therein a tape;
a tape, a drum, and first and second reels which are all incorporated in the housing;
a tape drive mechanism incorporated in the housing and feeding the tape;
a detecting means incorporated in the housing for detecting a rotation of the reel; and
a converting means incorporated in the housing for converting a signal concerning a rotation detected by the detecting means into a signal concerning a rotation speed.
According to another aspect of the present invention, there is provided a recording and reproducing system formed of a tape cartridge and a recording apparatus, comprising:
a cartridge formed being formed of;
a housing incorporating therein a tape,
a tape, a drum, and first and second reels which are all incorporated in the housing,
a tape drive mechanism incorporated in the housing and feeding the tape,
a detecting means incorporated in the housing for detecting a rotation of the reel, and
a converting means incorporated in the housing for converting a signal concerning a rotation detected by the detecting means into a signal concerning a rotation speed; and
a recording and reproducing apparatus using the tape cartridge being formed of;
a tape cartridge accommodation portion for accommodating therein the tape cartridge,
a means for electrically connecting to the converting means and the tape drive mechanism in the tape cartridge,
a calculation circuit for receiving and accumulating a pulse signal concerning the rotation speed and generating a control pulse signal corresponding to an accumulation value accumulated, the control pulse signal indicating a pulse number at every second, and
an output circuit for outputting the control pulse signal to the tape drive mechanism.
