Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cassette recorder, and more particularly to an improvement in its tape drive mechanism.

A cassette recorder uses a cassette tape as a recording medium, and is composed of a head mechanism, a tape drive mechanism, an amplifier, etc.

The tape drive mechanism of such a cassette recorder has a play function that sends the tape at a constant speed while keeping it in contact with the head during recording and playback, a fast winding function that sends the tape away from the head at high speed in the forward or reverse direction, and these functions. It has a function to stop the tape from the play or fast-winding state, a function to temporarily stop the tape in the middle of recording or playback, etc. Each of these functions includes tape constant speed drive mechanism, hub drive mechanism,
This is realized by a brake drive mechanism, a head and pinch roller slide mechanism, an operation switching mechanism, etc.

By the way, the operation switching mechanism in the conventional tape drive mechanism is, for example, as shown in FIG.
A plurality of selection switches S1 to S6 are provided to select each operation of playback, fast forward, rewind, stop, and pause, and the corresponding operation mode is selected according to the control signal sent from each selection switch S1 to S6. It was configured to switch to . In addition to these selection switches S1 to S6, an operation switch S7 for ejecting the tape is often provided.

For this reason, the selection switch of the operation switching mechanism becomes narrow and the operation becomes complicated.

The present invention has been devised in view of these points, and its purpose is to provide a cassette recorder with fewer selection switches, excellent operability, and advantageous design.

The present invention, which achieves these objects, includes a plurality of play operation setting means for sending the tape at a predetermined speed while in contact with the head, and sending out control signals for performing play operations such as recording or playback; a plurality of quick-winding operation setting means for sending control signals for causing a fast-winding operation in which the tape is moved away from the tape in the forward or reverse direction at high speed; The present invention is characterized by comprising: a standby state setting means for sending a control signal for setting a play operation standby state in which the play operation is stopped; and a tape ejecting means for ejecting the tape from the play operation standby state.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is an explanatory diagram of the configuration of an operating section showing an embodiment of the present invention, and FIG. 3 is an explanatory diagram showing the positional relationship between the tape TP and the head HD in each operation mode of the present invention.

In FIG. 2, S1 is a recording mode selection switch, S2 is a playback mode selection switch, S3 is a fast forward mode selection switch, S4 is a rewind mode selection switch, S5 is a stop mode selection switch, and S5 is a stop mode selection switch.
7 is a tape ejection operation switch.

Immediately before installing the tape, connect the tape TP and head.
The positional relationship of the HDs is sufficiently far apart as shown in Figure 3a, but immediately after this installation (after completion), a mechanism linked to the installation detects this, and as shown in Figure 3c, , the tape TP is stopped close to the head HD. That is, it is in a standby state for a play operation, which will be described later (in addition, PD in FIG. 3 is pad). In the recording mode, the tape TP is fed at a predetermined speed while contacting the head HD, as shown in Figure 3b, according to the control signals (on/off signals) sent from the selection switches S1 and S2. It will be done. Further, in the reproduction mode, the tape TP is sent at a predetermined speed while contacting the head HD according to a control signal sent only from the selection switch S2. Note that these recording modes and playback modes are referred to as play operations in this specification. In fast forward mode and rewind mode,
According to the control signals sent from the selection switches S3 and S4, the tape TP is moved in the forward direction (towards the winding hub) or in the reverse direction (toward the supply side) while being sufficiently far away from the head HD, as shown in Figure 3a. (toward the hub) at high speed. Note that these fast forward mode and rewind mode are referred to as fast winding operation in this specification.
When the selection switch S5 is operated in these play operation or fast winding operation states, according to the control signal sent from the selection switch S5,
As shown in Figure 3c, the tape TP is close to the head HD, or the tape TP is close to the head HD.
The player stops when lightly touching the button, and enters the play operation standby state. When the tape ejection operation switch S7 is operated in such a play operation standby state, the tape TP is ejected from the head as shown in Figure 3a.
The tape can be moved far enough away from the HD to eject the tape TP.

With this configuration, the conventional temporary stop selection switch can be omitted, and the number of selection switches can be reduced to improve operability. This also increases the degree of freedom in arranging the selection switches and operation switches, which is advantageous from a design standpoint. Furthermore, when performing recording or playback operations, the distance between the tape TP and the head HD is narrow or zero, so the head HD
The time it takes to touch TP will be reduced, and you will always have the convenience of traditional pause mode.

In addition, it is possible to automatically shift to a play operation standby state or to automatically shift to a tape ejection operation in accordance with an end detection signal from a known tape end detection mechanism.

Further, in the above embodiment, an example is shown in which a selection switch and an operation switch are used, but the control signal may be generated by operating a lever. Furthermore, the present invention is characterized by how the control signals are generated, and the mechanism for performing operations based on these control signals is the same as that of the conventional device.

As explained above, according to the present invention, a cassette recorder with excellent operability and advantageous design can be realized.
