Abstract

PURPOSE:To eliminate the need for troublesome operation and to prevent accidental erasure for the already recorded part by discriminating the operating mode just before the mode is transited to the present reverse recording pause mode from an old-mode memory section and applying control that no mode change takes place when the old mode memory section shows the reverse recording paly mode. CONSTITUTION:When the running direction of a tape is in reversing direction and the stop mode is selected, and when the recording switch 11 is depressed, a recording pause command is inputted from an operation switch section 10 to a switch input section 61, the stop mode is stored in the old-mode memory section 42, the reverse recording mode is stored in the present mode memory section 41 and a control signal is outputted from a control output section 62 so that the reverse recording pause mode is obtained for the mechanism 20. In depressing a forward play switch 13, similarly, the control signal is outputted to bring the mechanism 20 into the forward recording play mode. In depressing the pause switch 12 at the reverse play mode, the control signal is outputted to bring the mechanism 20 into the reverse recording pause mode.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a tape recorder having a mechanism capable of recording and reproducing in the forward and reverse directions with a tape attached thereto.

BACKGROUND OF THE INVENTION In recent years, auto-reverse type tape recorders have been widely used because of their ease of operation, and when the tape has finished running in the forward direction during recording or playback, it automatically switches to running the tape in the reverse direction. However, with conventional auto-reverse tape recorders, when moving from recording pause mode to recording play mode, it is possible to directly move from the reverse recording pause mode to the reverse recording play mode or the forward recording play mode. There are tape recorders that can move from the reverse side recording pause mode to the reverse side recording play mode, but cannot directly change to the forward recording play mode.

Problems to be Solved by the Invention However, in tape recorders that can directly move from the recording pause mode on the reverse side to the recording play mode on the forward side and record on the forward side, recording starts from the forward side and then reaches the reverse side. There was a serious problem in that if the user accidentally pressed the switch for normal recording play after performing a recording pause operation, the previously recorded portion would be erased and a new recording would be made.

In addition, for tape recorders that cannot change from the recording pause mode on the reverse side to the forward recording play mode, if the running direction immediately before starting recording is the reverse side and you try to start recording immediately, you can directly switch from the reverse recording pause mode to the forward recording play mode. There is a problem in that if you do not change to the forward rotation recording play mode, you must first change the running direction to the forward rotation side, then change to the forward rotation side recording Bose mode and change to the recording play mode, which is a cumbersome operation. Furthermore, in the case of recording FM broadcasts, etc., there was a problem of losing the opportunity to start recording.This was done in consideration of the problem of the present invention, and only the start of recording is changed from the reverse recording pause mode to the forward recording play mode. can move,
To provide a tape recorder that does not shift from a reverse recording pause mode to a normal recording play mode when the reverse recording play mode is changed to a reverse recording pause mode after the start of recording.

Means for Solving the Problems In order to solve the above problems, the tape recorder of the present invention includes a current mode memory section that stores the current operating mode of the mechanism section, and a memory section that stores the current operating mode of the mechanism section, and a memory section that stores the current operating mode of the mechanism section. an old mode memory section for storing an operation mode of the current mode memory section, a current mode memory determining means for determining the contents of the current mode memory section, and an old mode memory determining means for determining the contents of the old mode memory section; When the mode memory section is in reverse recording pause mode, when the forward play operation switch is pressed and a forward play command is input to the switch input section, when the old mode memory section is in stop mode or pause mode, the mechanism section is The control output section outputs a control signal so as to be in the transfer recording play mode, and when the old mode memory section is in the reverse recording play mode, the control output section controls the mechanism section so that the mode does not change. It is configured to do so.

According to the above-described structure, when the forward play switch is pressed while the current operation mode of the mechanism section is the inversion recording pause mode, the operation mode immediately before shifting to the current inversion recording pause mode is changed to the old mode. Judging from the memory section, if the previous operating mode is reverse recording play mode, it will not change to forward recording play mode, so there is no chance of accidentally erasing the already recorded part, and if the previous operating mode is stop mode. Alternatively, in the case of the pause mode, since the mode immediately shifts to the forward recording play mode, there is no need for troublesome operations at the time of starting recording, and there is no chance of losing an opportunity to start recording.

The control output section outputs a control signal to enter the recording play mode, and when the old mode memory section is in the reverse recording play mode, the control output section controls the mechanism section so that the mode does not change. If the normal rotation play switch is pressed while the operation mode of the mechanism is in the reverse recording pause mode,
The operating mode immediately before switching to the current reverse recording pause mode is determined from the old mode memory section, and if the immediately preceding operating mode is reverse recording play mode, it will not shift to forward recording play mode, so the previously recorded portion will be erased by mistake. If the previous operation mode is stop mode or pause mode, it will immediately switch to forward recording play mode, so there is no need for complicated operations when starting recording, and you will not lose the opportunity to start recording. do not have.

In addition, in this embodiment, the explanation of starting recording has been given using the case where the recording switch is pressed in the stop mode, but the recording switch may be pressed in the pause mode.

Effects of the Invention As described above, the present invention includes a current mode memory section that stores the current operation mode of the mechanism section, an old mode memory section that stores the operation mode of the mechanism section immediately before shifting to the current operation mode, and a previous mode memory section that stores the operation mode of the mechanism section immediately before shifting to the current operation mode. A determining means is provided for determining the contents of the memory section, and when the current mode memory section is in the reverse recording pause mode, when the forward play operation switch is pressed and the forward play command is input to the switch input section, the old mode memory is The control output section outputs a control signal so that the mechanism section is in the forward recording play mode when the section is in the stream mode or the pause mode, and the control output section outputs a control signal so that the mechanism section is in the forward recording play mode, and when the old mode memory section is in the reverse recording play mode. By controlling the mechanism so that the mode does not change, it is possible to move from the reverse recording pause mode to the forward recording play mode when starting recording, eliminating the troublesome operation of switching the running direction. You will not lose the opportunity to start recording, and even if you accidentally press the forward play switch during the reverse recording pause, you will not be able to switch to forward recording play mode, so you can erase the part that has already been recorded. The practical effect is great because it does not get stored away.
