Concerning the feeding and positioning of the recording head tbll In the above-described configuration, when the storage container 2 is loaded and the loading section 76 is locked, the motor 12 (driven by the magnetic sheet) 1
rotates, and the recording head 14 records or reproduces information.

In order to cause the recording head 14 to step between tracks, the electromagnet 44 intermittently attracts the suction blade 34, and the pawl drive lever 31 is rotated clockwise. Due to this rotation V), as described above, the head control member 21 is moved to the right of the X axis by the feed pawl 36 by the amount p described above. When the attraction of the electromagnet 44 stops, the control section paulownia 21 is activated by the spring 22.

By adjusting , it is possible to determine the feed amount suitable for the track pitch and to distribute the above component force, thereby increasing the degree of freedom in the configuration of the device tJt. In the above example, two sets of feed claws 36, 37 and position regulating claws 51, 52 are provided, but it is clear that the same effect can be achieved even if one set of each is provided, and the number of these sets is It is determined by the feed amount between tracks and the workability of the ratchet part.・Sara lko・'1! It is of course possible to use other intermittent drive mechanisms in place of the LIa stone '44.

Although the above-mentioned specific example was an example in which the recording tracks were provided concentrically on the magnetic sheet, the present invention can also be applied to a case where the recording tracks are provided in a spiral shape. To do this, a continuous drive device W such as an elastic member or a motor is used instead of the electromagnet 44, and the feed pawls 36, 37, position regulating pawls 51, 52, and pawl drive lever 31 are used ('C Kia Temple)! ! String 2! ! ! Instead of the counter feed pawl 42, a transmission mechanism and clutch means for continuous operation may be provided instead of the counter feed pawl 42.

Regarding the measurement of track length, the track length measuring means described below is a feature of this invention.
Follow the specific example shown in the figure! An example of counting the number of recorded or reproduced tracks in the case where the tracks are arranged in a circular shape on the ICIC seat track will be carried out ten times.

Each time the electromagnet 44 operates and attracts the attraction piece 34, the pawl drive lever 3I rotates counterclockwise as described above, and the drive gear 45 is rotated by the angle β by the counter feed pawl 42, but the storage container 2 Since the V-groove of the counter wind turbine 3 (Fig. 1) provided at Rotate twice. At this time, the reverse rotation of the drive gear 45 is prevented by the blocking claw 48a of the plate spring 48. As described above, the number of recorded tracks can be determined from the relative position between the keypad 3a of the counter windmill 3 and the index 2b engraved on the storage container.

In the above device, is the key in storage container 2? Although the counter pawl portion 3 having #3a is provided, it is also possible to provide an index on the cutter drive shaft 46 and provide a counter means on the main body of the recording or reproducing apparatus. In addition, when recording tracks are provided in a spiral shape, the amount of recorded or reproduced tracks can be determined by providing a counter feed claw 42 (instead, a transmission mechanism and a clutch means for continuous movement). be able to.

In the above device, the head control member 21 and the counter drive gear 45 (and the counter windmill 3) are driven by the common pawl drive lever 31, so the structure is simple and the operation is highly reliable. Furthermore, the inertia of the driving portion can be reduced, the responsiveness of the recording head is good, and the overall size of the apparatus can be reduced.

5I11Note: The power of the head carrier drive spring 15, which is the driving source for feeding the recording head, is stored in the head carrier drive spring 15, which is the drive source for feeding the recording head, when the operation (related to this This is done as follows.

This is the difference. Components shown with the same reference numerals as in each of the pruned figures in Figure 6 are as follows:
Since the structure and operation are basically the same as those described above, detailed explanation thereof will be omitted.

In FIG. 6, 121 is a head control member, and the shaft 1

The follower bin 16 implanted in the head carrier 13 is in contact with the ratchet portion 121b.
The cam lift has 16 follower pins, whereas the cam lift has 16 follower pins.
is decreased so that it moves by exactly l tracks. 122
The spring 125 is a bottle, and the C1 bottle 125 is applied to the head control member 121, and the biasing force of the spring 122 is always applied counterclockwise to the head control member 121 via the bottle 125. Head control member 121
The initial position of is regulated by a regulating portion fixed to the bottle 25 and the housing 80. Reference numeral 136 denotes a feed pawl, which is pivotally supported by one end of the pawl drive lever 31 via 1lII35, and is biased counterclockwise by a spring 1381. The claw portion 136a of the feed claw 136 is capable of engaging with the ratchet of the head control member 121.

On the other hand, ]51 is a position regulating pawl, to which a clockwise biasing force is applied by a spring 153 about a shaft 155, and its pawl portion ]51a can engage with the ratchet portion 121b.

When the magnet 44 attracts the attraction piece 34 provided on the drive lever 3, the drive lever 31 rotates clockwise, and as a result, the counter drive gear 45 is rotated.

Also in the specific example shown in FIG. 6, the head control member 121
Since the cam lift of the C cam section 12]a decreases in response to the clockwise rotation of the head iG control section + A'l 21, the cam lift of the C cam section 12]a decreases. Since the component force of the head gear rear drive spring 15 is applied via the first abin 6, the operating force thereof can be extremely small. Therefore, similarly to the specific example described above, it is possible to reduce the driving force of the rock 44.

When the eject lever 61 is pushed upward on the y-axis in order to prevent the number of magnetic sheet mosquito storage containers 2 from increasing, the force of the spring 5 is stored, and the eject lever 61 is
