Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is effective for use in reciprocating tape recorders, especially multi-track digital music tape recorders. This is a trend, and research and development of digital recorders for music is progressing.

An example of the conventional tape recorder mentioned above will be explained below with reference to all the drawings.

FIG. 3 is a front view showing a tape running guide section of a conventional tape recorder. In FIG. 3, 1 is a head, 2 is a slit, and 3 is a next tape edge position regulating section provided at the bottom of the head, and the lower edge of the running tape runs in sliding contact therewith. 4 and 5 are tape guides provided on the left and right sides of the head 1, and the guide surfaces are tapered. 8. 9.
10. Reference numeral 11 indicates seven flange portions provided on the guide surface of the tape guide 4.6 to prevent excessive displacement of the tape, 12 indicates a chassis or head mounting plate, and 13 indicates a tape.

The operation of the tape recorder configured as described above will be explained below.

When the tape 13 runs in either the left or right direction, the tapered surfaces 6, 7 of the tape guides 4, 6 always generate a downward force, and the tape 13 runs while sliding against the edge regulating portion 3 of the head 1.

Problems to be Solved by the Invention However, if you try to record back and forth in this state,
Although the dimension from the lower edge of the tape 13 to the recording area can be maintained with high accuracy, the tape is sometimes used with the upper and lower sides changed, and there is no variation in the width of the tape, so it is possible to maintain the dimension as it is. A reciprocating system has been realized for digital audio recorders that require high multi-track positional accuracy since there is a discrepancy between the track position on the tape recorded reciprocally and the track position recorded in a different direction, and the compatibility of the recorded tape has been realized. The problem was that it was very difficult to maintain the

In view of the above-mentioned problems, the present invention provides a reciprocating tape recorder in which the recording or playback position can be correctly obtained even when the tape running direction is changed or the tape is replaced, and is not affected by variations in the tape width dimension. It provides:

Means for Solving the Problems In order to solve the above-mentioned problems, the reciprocating tape recorder of the present invention includes a pair of tape edge position regulating sections above and below the slit portion, which are provided at a slightly larger interval across the tape width for regulating the tape edge position. The apparatus is equipped with a multi-track head having a multi-track head, and a tape running guide means in which the edge position regulating section of the running tape can be switched depending on the running direction of the tape.

Effect of the present invention With the above-described configuration, when the tape is run back and forth, the edge position of the tape, which is automatically regulated according to the running direction, is switched, and recording is performed with high precision at a corresponding predetermined position on the tape based on the edge position. Since it is played back, it is possible to guide the tape running with extremely little track misalignment even when using a multi-track head on extremely narrow tracks of a digital recorder, and it is possible to guide the tape running with extremely little track misalignment, even if there are variations in tape width. It can be recorded at the location.

EMBODIMENT A reciprocating tape recorder according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a front view of the main parts of a reciprocating tape recorder according to a first embodiment of the present invention when traveling in the forward direction. In FIG. 1, reference numerals 14 and 15 are tape edge position regulating parts, and step parts 16 and 16 are provided above and below the slit part 2, vertically symmetrical with the slit 2 and at intervals slightly wider than the tape width.
．． Reference numeral 17 is a tape guide, and flange surfaces for regulating the height of the tape are provided vertically at intervals slightly wider than the tape width.

18.19 is the tape guide surface of tape guide 16.17,
20.21, 22.23 are the flange surfaces of the tape guide 16.17, and 24, 25.26 are recorded on the lower half of the tape by the lower half slits positioned t'' with high precision from the height regulating part 14. The arrow indicates the tape running direction.

Reference numeral 27 denotes a head height switching member, which is in a state of being moved to the right, and at this time the head 1 is in a low first position. Therefore, the edge position regulating portion 14 comes into sliding contact with the upper edge of the tape 13,
The lower edge position regulating section 15 is not working. Instead, the lower edge of tape 13 has tape guides 16.17.
The lower flanges 22 and 23 of the two abut against each other to guide the travel.

FIG. 2 is a front view of the main part of the first embodiment during backward running, and shows the head height switching member moved to the left in conjunction with the switching of the tape running direction. That is, by setting the tape traveling direction in the direction of the arrow in the figure, the head 1 is pushed up, the edge position regulating portion 16 comes into sliding contact with the lower edge of the tape, and the tape guide flange 20.21 comes into sliding contact with the upper edge of the tape. In this state, the tape 13 runs to the right.

28, 29, and 30 indicate tracks recorded by the upper half slit positioned with high precision from the edge position regulating section 16. The tape surface does not necessarily need to be in sliding contact with the tape guide surfaces 18 and 19.

As described above, according to this embodiment, the multi-track head has a pair of tape edge position regulating parts provided at a spacing slightly larger than the tape width to regulate the edge height of the tape running above and below the slit part, and the tape running. A tape guide means is provided to guide the tape running so that the abutment location between the tape edge and the height regulating section can be switched up or down depending on the direction, so even if there is variation in tape width, the tape edge can be accurately moved from the reference tape edge. It is possible to realize a reciprocating tape recorder which can record and reproduce data and which does not cause track position deviation even when the tape is moved vertically.

In the above embodiment, the height of the head is moved between two positions in conjunction with switching the tape running direction, but it can also be done by switching the height of the tape running height regulating members on the left and right sides of the head. It is also possible to switch the longitudinal tilt (t) of either the head or the tape running height regulating member, or to switch the edge regulating position of the tape at the shield portion. Also, instead of the flange surfaces 20, 21, 22, and 23 shown in FIGS. 1 and 2, it is possible to press the tape edge by using a spring-loaded flange surface that contacts with a weak spring force. This can prevent the pressing force on the tape edge from becoming excessive due to variations in relative height deviation.

Effects of the Invention As described above, the present invention has a multi-track head having a pair of tape edge position regulating parts arranged at a slightly larger interval than the tape width for regulating the tape edge position above and below the slit part, and a multi-track head having a pair of tape edge position regulating parts arranged at a slightly larger interval above and below the slit part. By providing a tape running guide means in which the edge position regulation of the running tape can be switched, it is possible to realize a reciprocating tape recorder that can record and reproduce with high precision from the reference tape edge even if the tape width varies. , which is extremely effective in maintaining compatibility.
