Abstract

PURPOSE:To operate an A mechanism and a B mechanism individually or simultaneously by placing the two tape driving mechanisms in switching operation and simultaneously operation with a common operation button. CONSTITUTION:When a changeover switch 9 is set to a side A or B, an A control circuit 5 or B control circuit 6 is operated by operating the operation button 8 to operate the A mechanism 1 or B mechanism 2 individually, performing sound recording,reproduction, rewinding, fast forwarding, stopping, etc. Further, the switch 9 is et to C and the A control circuit 5 and B control circuit 6 are operated with the operation button 8; the A mechanism and B mechanism 2 are operated simultaneously to perform simultaneously sound recording, simultaneous reproduction, simultaneous rewinding, simultaneous fast forwarding, simultaneous stopping, etc. Then, a sound recording function is provided to only either of the A control circuit 1 and B control circuit 2 to obtain a dubbing function.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a double cassette tape recorder using an electronically controlled tape drive mechanism.

BACKGROUND OF THE INVENTION In recent years, double cassette tape recorders have become popular as dubbing cassette tape recorders.
The operation button device used to control the mechanism is also changing from a pure mechanical control system to an electronic control system.

A conventional double cassette tape recorder will be described below with reference to the drawings.

3 and 4 show a conventional double cassette tape recorder. In Figure 3, 1 is one tape drive mechanism of a double cassette tape recorder;
Hereafter, this will be referred to as the mu mechanism. 2 is the other tape drive mechanism, hereinafter referred to as the B mechanism. 3 is an operation button device for the B mechanism 1, 4 is an operation button device for the B mechanism 2, and FIG. 3 shows a pure mechanical control system. In addition, in Fig. 4, 1, 2, 3 and 4 are the same as described above, 5 is a circuit for operating and controlling the mechanism 1;
Hereafter, it will be referred to as the system control circuit. Reference numeral 6 denotes a circuit for operating and controlling the B mechanism 2, and is hereinafter referred to as a B control circuit. Figure 4 shows the electronic control system. The above-mentioned operation button devices 3 and 4 are capable of performing recording, playback, rewind, fast forward, stop, etc.

The operation of the double cassette tape recorder configured as described above will be explained below. First, by pressing the operation button device 3 of the system mechanism 1, the system mechanism 1 is operated. The same goes for 2 in B mechanism 2.

Furthermore, it was also possible to simultaneously operate the M mechanism 1 and the B mechanism 2, and simultaneously record and dubbing from the M mechanism 1 to the B mechanism 2 or from the B mechanism 2 to the M mechanism 1.

Problems to be Solved by the Invention However, in the above configuration, the M mechanism 1 and the B mechanism 2 require respective operation button devices 3.4, and two sets of operation buttons for recording, playback, rewind, fast forward, stop, etc. In other words, since at least 10 or more buttons are attached (configured), the mechanism configuration becomes complicated, which increases the cost, and there are problems in that miniaturization is difficult because there are too many operation buttons. .

In view of the above-mentioned problems, the present invention provides a double cassette tape recorder in which two tape drive mechanisms can be operated individually or simultaneously using one set of operation buttons.

Means for Solving the Problems In order to solve the above problems, the double cassette tape recorder of the present invention has a configuration in which the two tape drive mechanisms can be switched and simultaneously operated using a common operation button. .

Operation The present invention has the above-described configuration, and by forming a set of operation buttons, even when it is desired to operate the M mechanism independently or when it is desired to operate the B mechanism independently,
Even when dubbing is desired, one set of operating buttons can operate two tape drive mechanism configurations independently and simultaneously.

EXAMPLE Hereinafter, a double cassette tape recorder according to an example of the present invention will be described with reference to the drawings.

An embodiment of the present invention is shown in FIGS. 1 and 2. FIG. In Figures 1 and 2, 1.2 is five mechanisms, B
Mechanism, 7 is mechanism 1, 8. Carr, 0.
2 =) $□, -Oe0,. --This is a controller that includes an electronically controlled system control circuit 6 and B control circuit 6 for operating the system, and a changeover switch 9 for operating the system mechanism 1 and the B mechanism 2 described above. 8
This is an electronically controlled operation button for operating the main mechanism 1 and the B mechanism 2 individually or simultaneously.

In the double cassette tape recorder configured as described above, when the selector switch 9 is set to M or B, the M control circuit 5 or the B control circuit 6 is operated by operating the operation button 8, and the M mechanism 1 or B is activated. Mechanism 2 can be operated independently.

This allows you to record, play, rewind, fast forward, stop, etc. In addition, the changeover switch 9
When set to C, by operating the operation button 8 in the same manner as described above, the MU control circuit 6 and the B control circuit 6 are operated, and the MU mechanism 1 and the B mechanism 2 are activated.
Can work simultaneously, simultaneous recording, simultaneous playback, simultaneous rewinding,
Various operations such as simultaneous fast forwarding and simultaneous stopping can be executed. Furthermore, by attaching the recording function to only one of the M control circuit 1 and the B control circuit 2 so as to be operable, a dubbing function is made possible.

As described above, according to this embodiment, by providing a changeover switch and a control circuit to a cassette tape recorder having two tape drive mechanisms, it is possible to operate the B mechanism or the B mechanism independently or simultaneously with one set of operation buttons. You can do it like this.

Effects of the Invention As described above, the present invention provides a common operation button for the two tape drive mechanisms, so that the two tape drive mechanisms can be operated and independently record, play, rewind, fast forward, stop, etc. In addition, the dubbing function can be enabled by simultaneously recording, playing, rewinding, fast forwarding, and stopping, or by attaching the recording function to only one of the M control circuit or the B control circuit so that it can operate. Furthermore, since there is only one set of operation buttons, the number of operation buttons can be reduced to 5 to 6 compared to the conventional one, which is advantageous not only for cost reduction but also for simpler design and miniaturization. Furthermore, since the operation button is electronically controlled, it becomes more effective when the operation button is used as a remote control box for remote control operation.
