図面を参照して詳細に説明する。 In a cassette tape recorder, the angle between the magnetic head and the magnetic tape deviates due to precision errors in the cassette tape container, making it impossible to optimize the positional relationship between the magnetic tape and the magnetic head. Standard tape is generally used to adjust the angle of the magnetic head during assembly at the factory. The present invention aims to provide a device in which the angle of a magnetic head is adjusted by rotating an electric motor, and will be described in detail below with reference to the drawings.

A sliding board 3 is slidably attached to the slide board 1 and is slidably displaced to the playing position by a playback operation.
The supporting plate 8 is a magnetic head board on which the magnetic head 9 is fixed, and the support plate 8 is a magnetic head board on which a magnetic head 9 is fixed, and a support plate 8 is provided at its center as a fulcrum for adjusting the height and angle of the magnetic head board 8. adjustment pin 1
0 is set. 11 is a guide pin that guides the magnetic head board 8; 12 is the guide pin 1;
1, and has the function of pressing and biasing the magnetic head board 8 in the direction of the sliding board 1. Reference numeral 13 denotes an adjustment shaft that is provided on the opposite side of the guide pin 11 and screwed onto the sliding board 1. Rotation of the adjustment shaft 13 rotationally displaces the magnetic head board 8. The angle with respect to the magnetic tape can be adjusted. 14 is a first rotation transmission shaft that transmits rotation to the adjustment shaft 13, and is rotatably attached to the support plate 3 and has a first bevel gear 1 on its upper part.
5 is provided. 16 is the first bevel gear 1
5 is provided with a second bevel gear 17 that meshes with the bent portion 1 of the support plate 3, and is a second rotation transmission shaft that transmits rotation to the first rotation transmission shaft 14.
8 and 19, and its axial direction coincides with the sliding direction of the sliding substrate 1. Reference numeral 20 indicates a motor installed on the fixed board 2, and reference numeral 21 indicates a screw 23 attached to the rotating shaft 22 of the motor 20.
This is a connecting member that is fixed to the connecting portion 24 of the second rotation transmitting shaft 16, and is connected to the connecting portion 24 of the second rotation transmission shaft 16 so as to be slidable in the axial direction. Further, the connecting member 21 is formed with an engaging groove 26 in which an engaging pin 25 provided on the connecting portion 24 of the second rotation transmission shaft 16 engages. In this configuration, the electric motor 20 is configured to rotate in the forward and reverse directions based on a correction signal obtained from a detection circuit that detects the angular deviation of the magnetic head 9.

くなり磁気ヘツド９の角度調整動作が完了する。 The present invention is constructed as described above, and the adjustment operation will be explained next. When a playback operation is performed from the stopped state, the sliding board 1 is slid to the playing position and the magnetic head 9 comes into contact with the magnetic tape. At this time, the second rotation transmission shaft 16 that transmits the rotation of the electric motor 20 is slid and displaced within the connecting member 21, resulting in the state shown in FIG. 1. In such a state, when a correction signal is applied to the electric motor 20, the rotating shaft 22 of the electric motor 20 rotates, and the rotation is caused by the coupling member 21 - the second rotation transmission shaft 16 - the second bevel gear 17 - the first The bevel gear 15 is transmitted to the adjustment shaft 13 via the first rotation transmission shaft 14 and causes the adjustment shaft 13 to rotate. When the adjustment shaft 13 rotates, the magnetic head substrate 8 is displaced about the adjustment pin 10, changing the angle of the magnetic head 9.
When the angle of the magnetic head 9 becomes optimal with respect to the magnetic tape, the correction signal to the motor 20 disappears, and the angle adjustment operation of the magnetic head 9 is completed.

本考案は有している。 As explained above, according to the present invention, since the angle of the magnetic head with respect to the magnetic tape can be adjusted by the rotation of the electric motor, the angle between the magnetic tape and the magnetic head can be adjusted depending on the accuracy error of the cassette tape container. Even if it deviates, it can be adjusted to the optimal condition. In addition, since the electric motor for angle adjustment is not mounted on the sliding board but on the fixed board, the sliding board becomes lighter and the sliding movement of the sliding board can be performed smoothly. This invention has.
