Description

[Brief explanation of the drawing]

FIG. 1 is a schematic plan view showing various members arranged on the back side of a main chassis of a tape recorder equipped with an automatic stop device according to an embodiment of the present invention, and FIG. FIG. 3 is a schematic plan view showing only the record lever in FIG. 1 taken out, and FIG. 4 is a schematic plan view showing only the record lever in FIG. A schematic plan view showing only the clever lever taken out, FIG. 5 is a schematic plan view showing only the REW/FF lever taken out from FIG. 1, and FIG.
A schematic plan view showing only the trigger lever in FIG. 1; FIG. 7 is a schematic plan view showing only the click plate in FIG. 1;
FIG. 8 is a schematic plan view showing only the slide plate in FIG. 1, and FIG. 9 is a schematic plan view showing only the slide plate in FIG. 10 schematically shows the record plate of FIG. 2 arranged along the right edge of the back of the main chassis in FIG. 1. A partial plan view, FIG. 11, shows the record lever of FIG. 3, the playfoot lever of FIG. 4, and the REW/REW lever of FIG. FIG. 12 is a schematic plan view showing a state in which the FF lever and the trigger lever shown in FIG. 6 are arranged in an overlapping manner on some members shown in FIG. 11. FIG. 13 is a schematic plan view showing the click plate shown in FIG. 7 placed over some of the members shown in FIG. 12, and the slide plate shown in FIG. FIG. 14 is a schematic plan view showing the state immediately before the state shown in FIG.
A schematic partial plan view mainly showing the movement of the click plate shown in FIG. 7 among the various members mentioned above when the play mode is set in the tape recorder shown in FIG. 1, and FIG. 15 is a partial plan view of the tape recorder shown in FIG. The movements of the various members mentioned above when the play mode is set on the recorder are shown in Fig. 7, which is already shown in Fig. 14.
FIG. 16, a schematic plan view excluding the movement of the click plate shown in the figure, shows the movement of the record plate shown in FIG. 2 among the various members mentioned above when the tape recorder shown in FIG. FIG. 17, which is a schematic partial plan view mainly showing the movement, shows the state of the tape recorder shown in FIG. 1 just before the stop mode setting button is pressed and the record mode is canceled, with the click plate shown in FIG. 7 and the state shown in FIG. 8. FIG. 18 is a schematic plan view of the tape recorder shown in FIG. 1, with the slide plate shown in FIG. 8 being moved to the left to set the fast forward mode. FIG. 19 is a schematic plan view showing the states of the various members mentioned above when the rewind mode is set by moving the slide plate of FIG. 8 to the right in the tape recorder of FIG. 1. FIG. 20 is a schematic plan view showing the states of the various members mentioned above in FIG. A schematic plan view showing the states of the various members described above when the automatic stop (automatic stop) mechanism starts operating, excluding the slide plate in FIG.
FIG. 21 shows the above-mentioned various situations immediately before the auto-shut-off mechanism terminates its operation due to an increase in the tensile force applied to the end of the magnetic recording tape in the tape recorder of FIG. 1 while the play mode is being set, and the play mode is canceled. A schematic plan view showing the state of the members in FIG. 8 excluding the slide plate;
FIG. 2 is a schematic plan view showing the states of the various members described above when the eject mode is set in the tape recorder of FIG. 1, with the slide plate of FIG. 8 excluded. 10... Main chassis (fixed board), 34... Play plate (play mode setting member), 90...

Claims (1)

[Scope of Claim for Utility Model Registration] A tape feed shaft rotatably supported by a fixed substrate of a tape recorder and engaged with a tape feed-out hub around which a magnetic recording tape is wound; a tape end detection lever that rotates due to the tensile force applied to the magnetic recording tape when the magnetic recording tape sent out from the tape reaches its end; and a tape end detection lever that engages with a play mode setting member disposed at a play mode setting position to set the play mode. a play hook member that holds the setting member at the play mode setting position; rotatably supported by the fixed board, starts rotating by the rotation of the tape end detection lever, and is fixed to the flywheel after the rotation starts; The playhook member engages with the play mode setting member by driving the abutment portion that the drive pawl contacts and the abutment portion that abuts the playhook member after the rotation starts and abuts the drive pawl of the flywheel to engage the play mode setting member. and a trigger member having; the drive pawl fixed to the flywheel and the abutting part of the trigger member causing the abutting part of the trigger member to drive the flywheel. An automatic stop device for a tape recorder, comprising a predetermined slope that reduces the amount of rotation of a trigger member required to bring it into contact with a pawl.
