Abstract

PURPOSE:To obtain a recoding standby state where no recorded part remains by controlling the operations of a cassette mechanism and a recording circuit by a microcomputer. CONSTITUTION:When a recording standby key 6 is depressed, the microcomputer MCP 1 controls the cassette mechanism 2 via a mechanism driving circuit 3, and performs the rewinding of a tape. After that, a signal being inputted to the MCP 1 via a rotation detection circuit 5 disappears. Therefore, the MCP 1 stops a rewinding operation, and sets a recording circuit 4 at a recording mute state, then, feeds the tape. And the erasure of the tape is performed by feeding the tape only by constant rotating speed as monitoring an input signal from the circuit 5. The MCP 1 sets the mechanism 2 at a temporary stopping state when the number of input signals from the circuit 5 arrives at a constant quantity, and sets the circuit 4 at a temporary recording standby state.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tape recorder, and in particular, to a recording standby device that can obtain a recording standby state in which recording can be started immediately with a single touch operation. It is related to.

[Conventional technology]

As a conventional recording standby device, for example,
As described in Japanese Patent Publication No. 7-143751, there is a system that after rewinding the tape, fast-forwards a certain amount of the tape, such as the leader tape portion, and then enters a recording standby state.

[Problem to be solved by the invention]

With the above conventional technology, there was no problem when trying to record using a new tape, but when trying to record using a previously recorded tape again, most of the recorded tape , so if you simply rewind the tape, fast forward a certain amount of the tape, and then put it into recording standby, you will not be able to record the part that has already been recorded before the part where recording starts. There was a problem that .

Therefore, if you want to use an already recorded tape to record again, you must rewind the tape, perform an erase operation, erase a certain amount, and then put it into recording standby, which is very time-consuming. .

An object of the present invention is to solve the above-mentioned problems of the prior art, and to solve the problems of the prior art when trying to reuse a recorded tape for recording.
To provide a recording standby device capable of obtaining a recording standby state in which no already recorded part remains in the part before the part where recording is started, without any effort.

[Means to solve the problem]

The above objectives are achieved by a microcomputer controlling the operation of the cassette mechanism and the recording circuit.

[Effect]

A microcomputer controls tape rewinding, and when a rewinding end signal is detected, the tape is run in a recording mute state, and after running a certain amount according to the input of a reel base rotation detection signal, it is placed in a recording standby state. .

〔Example〕

Hereinafter, a simple embodiment of the present invention will be explained with reference to FIG.

In FIG. 1, when the recording standby key 6 is pressed,
The microcomputer 1 controls the cassette mechanism 2 via the mechanism drive circuit 3 to rewind the tape. When the tape rewind is completed, the signal inputted to the microcomputer 1 through the rotation detection circuit 5 disappears. Therefore, the microcomputer 1 stops the rewinding operation, puts the recording time wI4 into a recording mute state, and controls the cassette mechanism 2 to run the tape. In this state, while monitoring the signal input by the rotation detection circuit 5, the tape is run by a predetermined number of rotations, thereby erasing a certain amount from the beginning.

When the signal inputted by the rotation detection circuit 5 reaches a certain amount, the microcomputer 1 activates the cassette mechanism 2.
is put into a temporary stop state, and the recording 4° circuit 4 is put into a temporary recording standby state.

Figure 2 shows the flow of the above operation.

〔Effect of the invention〕

According to the present invention, when attempting to record using a recorded tape again, it is possible to easily create a recording standby state in which no previously recorded portion remains before the portion where recording starts. You can easily get it without spending too much.
