Abstract

PURPOSE:To prevent missing of opportunity of recording and to prevent accidental erasure of the already recorded part by bringing the tape recorder to the forward reversing/recording play mode from the mode just before when a forward play switch is depressed at the reverse recording pause mode. CONSTITUTION:A present mode memory discriminating means 51 discriminates the content of a present mode memory section 41 and old-mode memory section 42, and when an operation switch 13 for forward play is depressed with the reverse recording pause mode for the memory section 41, a forward play command is inputted to a switch input section 61 to brind the memory section 42 to the stop mode and when the memory section 41 is at the pause mode, a control output section 62 outputs a control signal by which the mechanism 20 is brought into the forward recording play mode. When the memory section 42 is in the reverse recording play mode, the output section 62 applies control to bring the mechanism 20 to the forward reproduction mode. Thus, a troublesome operation for changeover of running direction is eliminated to eliminate the loss of opportunity of recording start and accidental erasure of the already recorded part is avoided.

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, which automatically switches to reverse tape running when the tape has finished running in the normal direction during recording or playback. 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 Bose mode to the reverse side recording play mode, but cannot directly change to the forward side recording play mode.

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

In addition, tape recorders that cannot move from the recording Bose mode on the reverse side to the recording play mode on the forward side, if the running direction immediately before starting recording is the reverse side and you try to start recording immediately, the tape recorder will enter the recording pause mode on the reverse side. Because it does not directly switch to the forward recording play mode, there is a problem that it is necessary to first shift the running direction to the forward rotation side, then change the recording Bose mode on the forward rotation side to the recording play mode. Moreover, in the case of recording FM broadcasts, etc., there was a problem of losing the opportunity to start recording.This invention was made in consideration of the disadvantages of the present invention, and only the start of recording is changed from the reverse recording pause mode to the forward recording play mode. To provide a tape recorder which can switch from reverse recording play mode to reverse recording pause mode after recording starts, and enters forward playback mode without shifting from reverse recording pause mode to forward recording play mode. In order to solve the above problems, the tape recorder of the present invention has a current mode memory section that stores the current operation mode of the mechanism section, and a current mode memory section that stores the current operation mode of the mechanism section, and a memory section that stores the current operation mode of the mechanism section. an old mode memory section for storing an operation mode of a mechanism 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 current 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 The control output section outputs a control signal so that the mechanism section enters the forward recording play mode, and when the old mode memory section is in the reverse recording play mode, the control output section releases the reverse recording pause mode for the mechanism section. and is configured to control the normal rotation playback mode.
It was completed.

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. Judging from the old mode memory section, if the previous operating mode is reverse recording play mode, it will not change to forward recording play mode but will go to forward playback mode, so there is no chance of accidentally erasing the already recorded part. If the previous operation mode is stop mode or pause mode, the mode immediately shifts to forward recording play mode, so there is no need for cumbersome operations at the start of recording, and no opportunity to start recording is lost.

As described above, according to this embodiment, there is a mechanism section that can record and play back in the forward and reverse directions with a tape attached, a control output section that controls this mechanism section, and an operation that operates the mechanism section. A switch section, a switch input section for inputting commands for the operation switch section, a current mode memory section for storing the current operating mode of the mechanism section, and a memory section for storing the operating mode of the mechanism section immediately before shifting to the current operating mode. 1, the current mode memory section is in the reverse recording Bose mode and the forward play switch of the operation switch section is pressed; When a forward play command is input to the input section, when the old mode memory section is in stop or pause mode, the control output section outputs a control signal so that the mechanism section enters the forward recording play mode; When the old mode memory section is in the reverse recording play mode, the control output section controls the mechanism section to be in the normal rotation play mode, so that the operation mode of the current mechanism section is in the reverse recording Bose mode. When the forward play switch is pressed at some point, the operation mode immediately before switching to the current reverse recording pause mode is determined from the old mode memory section, and if the previous operation mode is the reverse recording play mode, forward recording is started. It does not change to play mode, but instead enters forward playback mode, so there is no chance of accidentally erasing the part that has already been recorded, and if the previous operation mode was stop mode or Bose mode, it immediately switches to forward recording play mode. 0'' In addition, if you try to immediately play the forward side during reverse recording Bose mode, there is no need to perform cumbersome operations when starting recording. It is very convenient because it can be switched.In this example, the explanation of starting recording was given using the example of pressing the recording switch in stop mode.
You can also press the recording switch while in Bose 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, A determining means is provided for determining the contents of these memory sections, 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 mode is set to the old mode. When the memory section is in stop mode or pause mode, the control output section outputs a control signal so that the mechanism section is in forward recording play mode, and when the old mode memory section is in reverse recording play mode, the control output section outputs a control signal. By controlling the mechanism so that it is in the forward rotation playback mode, it is possible to move from the reverse recording pause mode to the forward rotation recording play mode to start recording, so there is no need to change the running direction. Even if you press the recording interval without performing any new operations, it does not change to the forward recording play mode, so the part that has already been recorded will not be erased, and the practical effect is that you can directly play the forward side. There is something big about it.
